Abstract

The invention relates to a ski (2), especially an alpine ski, comprising several layers arranged between a gliding surface and a cover layer, which form at least one sandwich element (7) in conjunction with a core arranged in-between the layers. The ski also comprises a fixing element (54, 55) arranged therein to fix a ski binding (6). The fixing element (54, 55) is arranged in a neutral layer -plane (58)- of the ski (2) when the latter is bent perpendicular to the gliding surface (27).

Description

Ski, especially alpine skiing

The invention relates to a ski, in particular an alpine ski, with a plurality of layers arranged between a tread surface and a cover layer, as defined in claim 1.

From DE 41 12 299 AI a ski with a support device for a ski binding is known. The support device supporting the coupling parts of the ski binding is articulatedly connected to the ski in the central area thereof via an axis extending transversely to the longitudinal direction of the ski, so that pivoting of the support device together with the ski binding around this central axis is made possible. Between the ski and the support device, resilient support elements are arranged in the area in front of the axis and in the area behind the axis, which provide a defined resistance to the pivoting movement of the support device relative to the ski. The disadvantage here is that due to the swiveling movements of the support device for the ski binding caused by loads relative to the ski, roll tendencies or difficulties in maintaining balance for the user can already lead to a fall. Furthermore, the forces to be transmitted by the user to the sports device, in particular the forces acting in the vertical direction, are delayed, making precise control of the ski more difficult.

Furthermore, a ski with a binding support plate is known from DE 21 35 450 A. This binding support plate is connected to the ski by means of bearing devices which are spaced apart from one another in the longitudinal direction of the ski and fixed on the upper side thereof. One of the bearing devices forms an articulated connection between the binding support plate and the ski, and the further storage device forms an articulated and guiding device between the binding support plate and the ski. The disadvantage here is that the bearing devices for the binding support plate attached to the top of the ski cannot withstand the forces occurring during driving, or the desired, unaffected elasticity or deformability of the ski cannot be achieved with large-sized bearing devices.

The present invention has for its object to provide a ski, in particular for the practice of alpine skiing, which has hardly any changes in the characteristic parameters even after the ski binding has been installed and which enables a simplified installation of the ski binding. This object of the invention is achieved by the features of claim 1. The surprising advantage resulting from the features of the characterizing part of claim 1 lies in the fact that the structure of the ski for assembling the ski binding remains completely unchanged and therefore the parameters which are considered the most favorable by the manufacturer, such as the bending characteristic, the bending stiffness distribution and the Breaking strength, secured even after the binding assembly. For the installation of the ski binding on the ski, any mechanical processing of the ski body, such as, for example, machining operations by drilling holes in the ski body, or chemical processing, such as, for example, gluing, is unnecessary. The mechanical processing has so far repeatedly caused a change in the characteristic values, for example the flexibility of the ski, which can be clearly recognized and registered using suitable measuring means. These disadvantageous effects are now largely eliminated by the claimed training. The support of the ski binding in the neutral zone or in the neutral layer of the ski, which is defined in the ski which is considered to be a composite body in the case of bending stresses directed perpendicular to the running surface, now enables a highly stable cross member to accommodate the ski binding in the construction of the ski without integrating it thereby negatively influencing the bending stiffness or the flexibility of the ski. The arrangement of the anchoring elements in the neutral layer of the ski keeps the tensile and compressive stresses of the anchoring elements to a minimum. As a result, the tensioning of the anchoring elements in the ski body or the forces acting on the ski body when the ski is bent are absolutely minimized and the multi-layer ski structure is optimally protected against its dissolution. The length of the neutral fibers or the neutral layer remains constant even when the ski is subjected to bending stresses, whereas if the ski binding is fixed on the top of the ski, the upper fibers are compressed or shortened when the ski is bent, and the lower fibers are stretched or elongated . When the ski is deflected, tensile stresses in the lower and compressive stresses in the upper cross-sectional area of the ski occur, whereas these oppositely directed force components are advantageously eliminated in the neutral layer. The stresses take on the value 0 directly in the neutral layer or on the corresponding zero line in the force diagram, which means that there is an absolutely force-free state. In narrow areas around the neutral layer or around the neutral plane, the tensile and compressive stresses are very low, which advantageously uses the best possible binding assembly position in terms of tensionlessness and freedom from forces. An embodiment according to claim 2 and / or 3 is advantageous, since this ensures that the ski binding is secured against tearing out, without having any significant influence on the ski parameters.

An embodiment according to claim 4 is also advantageous, since the surface pressure in the ski body can thereby be greatly reduced and the stress on the individual components is particularly low.

With the design according to claim 5, it is possible to assume individual mounting positions of the ski binding relative to the ski.

Due to the design according to claim 6, the components of the ski, which essentially influence the properties of the ski composite construction, which are usually arranged near the edge zones thereof, are completely unaffected by the anchoring elements integrated in the ski body or by their geometry or theirs Dimensions not changed.

According to the advantageous embodiment variant according to one or more of claims 7 to 9, a highly stable support element can be used for the ski binding, which has no influence on the natural flex of the ski due to the corresponding mounting on the ski. In addition, this configuration eliminates the need for complex compensation mechanisms in the ski binding to compensate for the movements of the binding body of the ski binding caused by the bending of the ski.

Due to the design according to claim 10, the anchoring element or

Anchoring position, a bending characteristic that is adapted to the ski body and optimally supplementing or influencing the bending characteristic of the ski body can be achieved.

An embodiment according to claim 11 is also advantageous since the surface pressure inside the ski body is thereby particularly low and relatively thin-walled anchoring elements can thus be used.

According to an embodiment as described in claim 12, a high-strength connection between the ski and the support element is possible, the components required for this being able to be produced relatively simply and inexpensively. In this case, an embodiment according to claim 13 proves to be advantageous, since the ski binding is thereby reliably held even with very high forces and undesired positional deviations are excluded.

According to an advantageous further development according to claim 14, different relative positions of the ski binding with respect to the ski can be assumed in a simple manner.

However, an embodiment according to claim 15 is also advantageous, since as a result the usual waistline or the usual course of the width of the ski can be maintained and the relatively far apart support points of the ski binding on the ski result in favorable force relationships.

According to claim 16, the width of the ski is not changed by the installation of the ski binding or the support element for the ski binding. In addition, abrupt variations in width, with reference to a top view of the ski, are avoided and harmoniously extending boundary edges of the ski body that increase the overall visual impression are achieved.

In the embodiment according to claim 17, the anchoring element can be embedded in the core of the ski in a simple manner.

An embodiment according to claim 18 is possible, since by fixing the anchoring elements in the relatively solid and large-volume core of the ski body, a reliable and highly stable fixing of the anchoring elements in the ski body is achieved.

The advantageous embodiments according to one or more of claims 19 to 21 enable the ski binding or the supporting element for the ski binding to be reliably fixed on the ski, with a releasable connection being provided on the one hand via the connecting elements and also the preload between the parts to be connected in easily regulated and can also be changed at a later date.

The embodiment according to claim 22 is also advantageous, since this results in an elevated contact position of the foot or the shoe of the user, which enables strong inclinations when cornering with the sports equipment without the shoe Touch the surface.

However, an embodiment according to claim 23 is also advantageous since the deformation movements of the ski caused by driving through undulating terrain are made possible without hindrance and stiffenings in areas, especially in the binding assembly area of the ski, are therefore avoided.

An embodiment according to claim 24 is also advantageous, since it enables the support element to be mounted very easily on the ski, and the construction of a highly stable and reliable connecting device for the two support element parts is possible due to the high-strength design thereof.

Due to the advantageous developments according to one or more of claims 25 to 29, the mounting of the support element on the ski can be carried out easily and in a short time. In addition, all parts relevant to the connection of the support element to the ski are effectively assigned to the two support element parts, which have high strength, which means that a correspondingly high connecting force can be applied.

Due to the advantageous further development according to one or more of claims 30 to 32, the guide device is formed between the two large-area support element parts, as a result of which the surface pressure between the guide parts of the guide track is very low and wear phenomena are thereby excluded even during hard and long-term operation. The decoupling of the longitudinal guide device from the joint arrangement, i.e. the joint arrangement and the guide device are separated from one another in terms of area, and also enables larger joint and guide parts.

The advantageous embodiment according to claim 33 prevents tension and changes in the safety-relevant trigger values between the coupling parts of the ski binding that hold the shoe when the ski is deformed or bent.

However, an embodiment according to claim 34 is also advantageous, since in this way both jaw bodies of the ski binding can be fixed immovably on this one support element part and the longitudinal compensation required for the unimpeded bending of the ski can take place directly between the two support element parts in an end region thereof . However, a further development according to one or more of claims 35 to 37 is also advantageous, since this enables the ski binding or the support element for the ski binding to be fixed quickly and easily. In addition, the support element or the ski binding can be released from the ski particularly easily at any time and without great effort.

With the advantageous embodiment according to one or more of claims 38 to 41, a particularly simple and largely automated fastening process of the ski binding or of the support element for the ski binding on the ski is achieved.

Due to the advantageous embodiment according to one or more of claims 42 to 50, a system for mounting a binding or a support element on a ski is created, which has a high reliability and significantly shortens the assembly process of the ski binding on the ski, thus also disassembly at any time the same without the use of tools.

Further advantageous developments are described in claims 51 to 53, because in this way the harmonious course of the characteristic curve of the flexural rigidity distribution of the ski is retained despite the high-strength anchoring elements.

In the advantageous embodiment according to claim 54, the anchoring element is formed in one piece in the ski body and, due to the preferably metallic material, has good preconditions for mounting the support element or for mounting the ski binding.

With the training according to claim 55, the usual outline shape of the ski is hardly changed and a harmonious appearance is created. In addition, in the case of skis with little waists, hooking between the support element parts or between the legs of the two support element parts of a pair of skis is excluded, which enables undisturbed driving.

Furthermore, a training is possible, as described in claims 56 and / or 57, since this also allows the articulation points to be assigned to the relatively large and dimensionally stable parts of the support element and the legs for mounting the ski binding or the support plate for the ski binding are fixed in motion with the Ski can be connected. The joint as well as the joint and guide device can then in the end regions of the plate part between this and with the Ski firmly connected legs can be formed.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

As an introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally etc. refer to the figure described and illustrated immediately and are to be transferred to the new position in the event of a change of position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

1 to 4 show an embodiment of a sports device 1 according to the invention, in particular a ski 2, with a support element 3 mounted thereon, which supports coupling parts 4, 5 of a ski binding 6 for releasable connection to a shoe of a user.

The sports device 1 or the ski 2 is formed from a sandwich element 7, which consists of several interconnected layers, approximately the central position of the multilayer sandwich element 7 represents a core 8 which has comparatively large cross-sectional dimensions in relation to the layers surrounding it. The core 8 preferably consists of wood, in particular of a plurality of lamellae 9, 10 which are glued to one another and thus connected to form a one-piece component and which are preferably formed from hardwood.

The support element 3, which is essentially U-shaped in cross section, is in this case of multiple parts, preferably of two parts, a first support element part 11, which is essentially L-shaped in cross section, via a connecting device 12 with a further support element part 13, which is also essentially L-shaped in cross section Above mentioned one-piece support element 3 can be connected, so that overall the substantially U-shaped cross-sectional shape of the support element 3 is formed.

The U-shape of the support element 3, which is related to cross-sectional planes, is present in this embodiment at least in end regions 14, 15 thereof, whereas the cross section of the support element 3 in an intermediate region 16 essentially corresponds to the cross section of a plate-like component. Accordingly, at least in the end regions 14, 15 of the support element 3, two legs 17, 18; 19, 20, which are spaced from one another approximately in accordance with the width of the ski 2, in the direction of the ski 2 arranged below a support surface 21 on the support element 3 for the foot of the user.

The legs 17, 18 assigned to the front end region 14 and spaced apart from one another by approximately the width of the ski 2 have bearing devices 22, 23 in an end region facing away from the support surface 21 for the foot of the user, by means of which the support element 3 also supports the sports device 1, in particular can be connected to the ski 2. Likewise, the legs 19, 20 of the support element 3, which are assigned to the end region 15 of the support element 3 and are likewise spaced from one another approximately in the width of the ski 2, have bearing devices 24, 25 in their lower end regions facing away from the support surface 21 for connection to the sports device 1, especially with the ski 2.

The substantially rectangular in plan view of the sports device 1 and oriented in its longitudinal extent essentially parallel to a longitudinal direction - arrow 26 - of the ski 2 and essentially parallel to a running surface 27 of the ski

Tread surface 28 aligned support surface 21 on the support element 3 thus has in this embodiment in the corner regions one in the direction of the underlying - lü ¬

The sports device 1 directed legs 17 to 20, which define the support surface 21 at a distance 29 above an upper side 30 of the ski 2. On an underside 31 of a substantially flat central plate part 32, which forms the support surface 21, of the support element 3, which is assembled via the connecting device 12 to form a one-piece component, a leg 17 to 20 is formed in each of the four corner regions, which leg is essentially at right angles from the The underside 31 of the plate part 32 protrude and is connected to the ski 2 in its end region facing the running surface 27 via a respective bearing device 22 to 25. The underside 31 of the central plate part 32 of the support element 3 is by a corresponding arrangement of the bearing devices 22 to 25 in the legs 17 to 20 and / or by a corresponding choice of the connection points with the ski 2, based on the vertical direction and / or by a corresponding choice of the length of the legs 17 to 20 is arranged at a distance 33 above the top 30 of the ski 2, so that between the support element 3, in particular between the central plate part 32 receiving the legs 17 and 20 and the top 30 of the ski 2 Free space 34 is formed, which allows the relative movements between the ski 2 and the support element 3, which will be explained in more detail below. The free space 34 between the bottom 31 of the support element 3 and the top 30 of the ski 2 is given over the entire length and width of the plate part 32 between this and the top 30 of the ski 2.

At least in the end regions 14, 15, the support element 3 is thus essentially U-shaped in cross section, the plate part 32 forming the support surface 21 for the foot of the user and, in the corner regions, the legs 17 to 20 preferably in one piece in accordance with the preceding description are molded.

Here, as already described above, the support element 3 is of multi-part design and has at least two support element parts 11, 13 with an L-shaped cross section, which can be assembled to form the one-piece support element 3 via the connecting device 12.

A separating and / or joining area 35 between the two cross-sectionally L-shaped support element parts 11, 13 runs in the longitudinal direction - arrow 26 - of the ski 2 and essentially parallel to the running surface 27. In the separating and / or joining area 35, the support element parts 1 1, 13 can be optionally assembled or separated from one another via the connecting device 12 to form the one-piece support element 3. Preferred are arrow 26 facing each other and in the longitudinal direction - Running leg plates 36, 37 of the support member parts 11, 13 additionally positively connected to each other. The mutually facing leg plates 36, 37 of each substantially L-shaped support element part 1 1, 13 thus form the substantially flat, multi-part plate part 32 of the support element 3 in the assembled state. For the positive connection of the two support element parts 11, 13, corresponding recesses 38, 39 are provided in the mutually facing longitudinal edge regions of each leg plate 36, 37, which enable a mutual positive connection.

In the simplest case, the leg plates 36, 37 of each support element part 11, 13 are flattened up to half the plate thickness, so that the flattened, mutually associated side areas of each support element part 11, 13 can be assembled and, in total, a substantially continuous, uniform thickness of the plate part 32 preserved. The flattened, mutually facing longitudinal edge regions of the two support element parts 11, 13 thus result in a simple fold connection which is secured against loosening by means of suitable fastening means 40, in particular by means of screws 41.

The form-fitting connection between the two support element parts 11, 13 oriented in the longitudinal direction - arrow 26 - of the ski 2 in the separating and / or joining area 35 in between can also be formed by a tongue and groove connection, as is shown schematically in FIG. 2 . For this purpose, the indentations 38 of the horizontally oriented leg plate 36 are designed such that a spring 42 is formed in the longitudinal edge region facing the other support element 13. This spring 42 is dimensioned such that it can positively engage in a groove 43 assigned to it in the leg plate 37 of the other support element part 13. The groove 43 is thus formed by the indentation 39 in the support element part 13. The mutually corresponding tongue 42 and groove 43 of the support element parts 11, 13 are connected to one another via the fastening means 40, in particular via the screws 41, in such a way that a relative movement between the two support element parts 11, 13 is prevented.

Of course, it is also possible to connect the support element parts 11, 13 to one another without the use of independent fastening means 40. Here, the support element parts 11, 13 are preferably non-detachably coupled to one another via snap connections. Such snap connections are known from the prior art and can for example be arranged in the longitudinal edge region of the support element part 11. Fende locking bar with an essentially circular cross-sectional shape and formed by a recess formed in the longitudinal edge region of the further support element part 13 with a substantially opposite, pan-shaped cross-sectional shape. Both support element parts 11, 13 are to be fed to one another for mounting the support element 3 or the ski binding 6 on the ski 2 and to be permanently connected to one another by applying a corresponding pretensioning force. By applying or exceeding this pretensioning force, the locking bar then jumps over into the locking recess, as a result of which the snap connection between the two support element parts 11, 13 is established. Such a snap connection is particularly in the case of materials with a sufficient modulus of elasticity, in particular in the case of

Plastics or fiber-reinforced plastics or composite materials, possible in a simple manner.

The support element parts 11, 13 are thus connected by the non-positive and / or positive connection via the connecting device 12, which comprises fastening means 40 and / or positive connections, to the one-piece support element 3, which overall has a high dimensional stability. The support element 3, which is two-part by the two support element parts 11, 13 but is combined to form a one-piece component via the connecting device 12, has in particular high torsional and flexural rigidity, all of which usually act on the support element 3

Torsion and bending forces, such as can occur when driving with the sports device 1, withstand. Due to the high torsional and bending stiffness of the support element 3, the coupling parts 4, 5 of the ski binding 6 remain completely unchanged in their relative position or relative position to one another under all operating conditions that occur during driving operation, so that the pretensioning of the coupling parts 4, 5 of the ski binding 6 onto the Shoe remains unchanged due to the absolutely bending and torsionally rigid or deformation-stable support element 3.

The support element 3 is coupled to the ski 2 in the end region 14 via an articulated connection 44. This articulated connection 44 between the support element 3 and the ski 2 in the front end region 14 relating to the direction of travel of the sports device 1 comprises the bearing devices 22, 23, in particular borehole-like recesses 45, 46 with a circular cross section in the legs 17, 18 and with these recesses 45 , 46 corresponding bearing journals 47, 48. These bearing journals 47, 48 are connected to the sports device 1 or to the ski 2 in a fixed manner and have an essentially circular cross section, the diameter of which corresponds essentially to the diameter of the associated recesses 45, 46, so - that a joint connection 44 between the support element 3 and the ski 2 that is as free of play as possible is ensured.

In the rear end region 15, which is distanced from the front end region 14 in the longitudinal direction - arrow 26 - of the ski 2, the support element 3 is connected in an articulated manner to the sports device 1 or with the ski 2 via a joint and guide device 49 and in the longitudinal direction - arrow 26 - The ski 2 is relatively movable, in particular translationally displaceable and movable. This joint and guide device 49 between the support element 3 and the ski 2 in the rear or further end region 15 relating to the direction of travel also comprises recesses 50, 51, which in particular as elongated holes in the longitudinal direction - arrow 26 - of the ski 2 the legs 19, 20 are formed, the width of which essentially corresponds to a diameter of bearing pins 52, 53 which are fixedly connected to the ski 2 and have a circular cross section. The slot-shaped recesses 50, 51 in the legs 19, 20 form in cooperation with the bearing pins 52, 53 fixedly connected to the ski 2, the joint and guide device 49, which both a rotational movement between the ski 2 and the support element 3 as well enables a translatory movement of the ski 2 relative to the support element 3 or relative to the legs 19, 20.

The journals 47, 48 are formed at the ends of an anchoring element 54 integrated in the ski body, which is aligned essentially parallel to the tread 27 or to the tread surface 28 and essentially transversely to the longitudinal direction - arrow 26 - of the ski 2 approximately over its entire length Width runs. The further rear bearing journals 52, 53, which are related to the direction of travel, are also formed at the ends of an anchoring element 55 of the same type, integrated in the ski body, which is also aligned essentially parallel to the running surface 27 or to the running surface 28 and also essentially transversely to Longitudinal direction - arrow 26 - of the ski 2 runs. The anchoring elements 54, 55, which are integrated in the ski body and spaced apart in the longitudinal direction - arrow 26 - of the ski 2 form via the bearing pins 47, 48; 52, 53 pivot axes 56, 57, which are aligned essentially parallel to the running surface 27 and transversely to the longitudinal direction - arrow 26 - of the ski 2 and in the two longitudinally - arrow 26 - of the ski 2 spaced-apart connection areas of the ski 2 with the Support element 3 each allow a rotational relative movement when the ski 2 is bent or bent, as is inevitably countered when driving through undulating terrain or when cornering due to the waist and / or the pretension height of the ski 2 ben is. The support element 3 with the coupling parts 4, 5 of the ski binding 6 fastened thereon does not influence the flexural rigidity or the flexibility of the ski 2, since the articulated connection 44 and the joint and guide device 49 between the support element 3 and the ski 2 enable the ski to work freely Ski body allowed. The natural flex of the ski 2 is thus retained and the ski binding 6 mounted on the support element 3 has no negative influence on the bending characteristic value provided by the manufacturer of the ski 2 or on the bending stiffness distribution of the sports device 1 which the manufacturer considers the most favorable.

The two pivot axes 56, 57 formed by the anchoring elements 54, 55 run absolutely parallel to one another when projecting onto a horizontal plane as well as when projecting onto a vertical vertical plane running transversely to the longitudinal direction - arrow 26 - of the ski 2. The anchoring elements 54, 55 integrated in the ski 2 for connecting the ski 2 to the support element 3 are arranged in a plane 58 oriented essentially parallel to the running surface 27 or to the running surface 28 and, under certain conditions, connect several in the longitudinal direction - arrow 26 - Center of gravity 59, 60 spaced apart from one another in relation to several cross-sectional sections of the ski 2 spaced apart from one another. The anchoring elements 54, 55 or the pivot axes 56, 57 are in any case arranged in the neutral fiber or in the neutral layer of the sports device 1 or the ski body, that is, the pivot axes 56, 57 and the anchoring elements 54, 55 are arranged in those areas in the ski body in which the tensile and compressive stresses which occur in the event of a load or in the event of deflection or deflection cancel each other out and become zero. The neutral fiber or neutral zone of the ski 2 largely untouched by tensile and compressive forces depends in particular on the elasticity modules of the individual layers of the ski 2 and on their thickness and shape or geometry, but normally runs in the area of the core 8 and thereby parallel to the running surface 27 and in the longitudinal direction - arrow 26 - of the ski 2. The neutral fiber or the neutral zone of the ski 2 is represented by the plane 58 and mostly runs parallel to the running surface 27 in approximately half the thickness of the ski 2 Especially in the case of a homogeneous, uniform ski body, this plane 58 connects all the focal points 59, 60 of the ski 2 running in the longitudinal direction - arrow 26 - in the individual cross-sectional sections of the ski 2. The swivel axes 56, 57 lie in plane 58 or in the neutral one Zone of the multi-layer ski body in particular and are aligned transversely to the longitudinal direction - arrow 26 - of the ski 2. In the exemplary embodiment shown, the neutral zone or the plane 58 of the ski body runs through the core 8, in particular through the hardwood core of the ski 2 Anchoring elements 54, 55 thus penetrate the core 8 in the transverse direction of the ski 2 and are thereby firmly connected to it or held there under pretension, so that displacements between the anchoring elements 54, 55 and the ski 2 are prevented. The anchoring element 54, 55 preferably extends continuously across the entire width of the ski 2 and forms the bearing pins 47, 48 at both ends; 52, 53 out. The preferably metallic anchoring elements 54, 55 penetrate the core 8, in particular the hardwood core, in this case through bores 61, 62. The core 8, which is essentially rigid and absolutely free from pulling out, integrates the anchoring elements 54, 55 and the pivot axes 56 formed by them , 57 absolutely tear-proof and high-strength held in the ski 2 or extremely rigid and unrelentingly fixed. The pull-out strength or the absolutely fixed fixation of the anchoring elements 54, 55 in the ski body can be increased by projections 63, 64 projecting like wings. The anchoring elements 54, 55 can be formed by bolt-like elements 65, 66 with a circular cross-section, the plate-like projections 63, 64 projecting radially from the lateral surfaces of the elements 65, 66. The plate-like projections 63, 64 can continuously taper in thickness with increasing distance from the central, bolt-like element 65, 66, so that cutting-like longitudinal edges are formed in the regions distanced from the central element 65, 66. The projections 63, 64 thus have an approximately triangular or cutting blade-like cross-sectional shape.

Several projections 63, 64 can also be arranged distributed over the circumference of the bolt-like elements 65, 66. However, two protrusions 63, 64 are preferably provided for each element 65, 66, the flat sides of which are oriented essentially parallel to the running surface 27 or parallel to the plane 58, so that the relatively high, perpendicular to the plane 58 or essentially perpendicular to the running surface 27 Forces can be safely absorbed and a deviation of the central, bolt-shaped elements 65, 66 in the ski body from the intended position is excluded. The projections 63, 64 on the anchoring elements 54, 55 result in a higher contact surface of the same in the ski body, so that a deviation, for example a lowering of the same in the ski body or a rotational movement of the same about the pivot axes 56, 57 is avoided. The diameter of the bearing pins 47, 48; arranged at the end regions of the anchoring elements 54, 55; 52, 53 is approximately 4 mm to 14 mm and preferably consists of a high-strength metallic material, for example of steel or also of metal alloys, such as, for example, Titanal. The wing-like projections 63, 64 of the anchoring elements 54, 55 in the ski body each run in level 58 or in the neutral fiber of sports equipment 1 or ski 2. Likewise, the pivot axes 56, 57 of the anchoring elements 54, 55 lie exactly in level 58 or in the neutral fibers of the ski structure and are transverse to the longitudinal direction - arrow 26 - the ski 2 aligned.

The sandwich element 7, which is made up of several layers and forms the sports device 1 or the ski 2, comprises, in addition to the essentially centrally arranged core layer or next to the core 8, in particular made of wood, further layers at least partially surrounding it. In particular, the sandwich element 7 has an upper flange 67 arranged in the upper edge regions of the ski body and a lower flange 68 assigned to the tread 27 or the tread surface 28. At least one upper flange 67 and at least one lower flange 68 are provided near the edge zones of the ski cut, these layers of ski 2 being made of materials of high strength and rigidity. Elastic inserts made of plastic or foam are preferably arranged between the core 8 and the upper and lower chords 67, 68. If necessary, a filler 69, in particular made of plastic or foam, can also be arranged between the core 8 and the supporting straps, which has a higher elasticity compared to the core 8 or a lower resistance under pressure loads and thus also a damping function in the body can take over. This composite of the core 8, the upper and lower chords 67, 68 and the filler 69 is surrounded on the one hand by the tread covering 28 and on the other hand by a shell 70 which has a high mechanical strength. The supporting straps and the core 8 and the filler 69 can optionally be surrounded by two shells, the outer shell 70 being hard and the inner shell being comparatively soft. As is known per se, the longitudinal edge regions of the shell 70 are supported directly on the running edges 71, 72 which delimit the tread surface 28 and which are preferably made of steel, as a result of which optimal power transmission is achieved.

The sports device 1 is therefore comparable to a rod made of composite material. The position and orientation of the neutral fibers - represented by plane 58 - is determined by the different elasticity modules of the individual layers and by the cross-sectional geometry of the ski 2. In the exemplary embodiment shown, the individual elasticity modules and geometries of the individual layers of the ski body are designed such that the center of gravity 59, 60 lies in the plane 58 or in the neutral fiber of the ski body. Of course, however, it is also possible for the center of gravity 59, 60 to be dependent on the individual elasticity modules and geometries of the individual layers or layers of the composite material lie next to the plane 58 or next to the neutral fibers of the ski body. Due to the cross-sectional halves of the ski body, which are generally symmetrical with respect to a vertical axis 73, in particular with the z-axis, the centroids 59, 60 always lie on this vertical axis 73. The previous descriptions refer to the effects of force perpendicular to the running surface 27 or to the top 30 of the ski 2, if the ski 2 is held in the shovel and end area. '

4 shows the course of tension of the ski 2 when it is bent about a horizontal axis directed transversely to the longitudinal direction - arrow 26. The stress curve is shown here in a highly simplified and schematic manner and exemplifies one of many possible stress curves. This diagram with the stress curve in the individual layers of ski 2 clearly shows the jumps at the individual material limits of the composite material. If the ski 2 bends, i.e. when the ski 2 is loaded perpendicular to the surface 30, the lower flange 68 acts as a tension belt and the upper flange 67 acts as a compression belt, with some of the tensile and compressive forces that occur being symbolized in part by arrows 74, 75 for the tensile forces and by arrows 76, 77 for the compressive forces. In the neutral fiber - plane 58 - the oppositely directed tensile and compressive forces cancel each other out and a tension zero line 78, which defines the neutral fibers or plane 58, is formed. The anchoring element 54, 55 for mounting the dimensionally stable support element 3 is arranged precisely at this tension zero line 78 or in the neutral fiber - plane 58. The direction of arrows 74 to 77 in particular provides information about the tensile or pressure conditions in the ski body and their length provides information about the amount or the magnitude of the forces.

As can be seen above all from FIGS. 2 and 3, the legs 17 to 20 of the support element 3 are inserted in recesses 79 to 82 in the sports device 1 or in the ski 2. These recesses 79 to 82 are arranged in the region of side cheeks 83, 84, the free space formed by the recesses 79 to 82 essentially corresponding to the volume of the legs 17 to 20 of the support element 3 to be inserted or inserted therein. Outer surfaces 85 to 88 facing away from one another on the legs 17 to 20 are largely flat with the side surfaces 89, 90 formed by the side cheeks 83, 84, so that a largely stepless transition between the legs 17 to 20 of the support element 3 and the side surfaces 89 , 90 is formed on the side cheeks 83, 84. Thus, the width of the sports device 1 is not increased even by attaching the support member 3 and individual Protrusions on the side cheeks 83, 84, which could cause the pair of skis to get caught when skiing, are excluded, since the side surfaces 89, 90 of the side cheeks 83, 84 are designed to be consistently flat or without substantial protrusions. The inclination of the outer surfaces 85 to 88 of the legs 17 to 20 of the support element 3 is adapted to the inclination of the side surfaces 89, 90 on the side cheeks 83, 84 of the ski 2, whereby generally two outer surfaces 85, 86; 87, 88 run diverging from one another and a theoretical line of intersection thereof is formed in the vertical direction above the running surface 27. Inner surfaces 91 to 94 of the legs 17 to 20 are absolutely perpendicular to the pivot axes 56, 57 and are as free from play as possible on inner boundary surfaces 95 to 98 of the

Recesses 79 to 82. In relation to the cross-sectional area of the support element 3, the outer surfaces 85 to 88 and the inner surfaces 91 to 94 of the legs 17 to 20 therefore run at an angle to one another, the inner surfaces 91 to 94 being perpendicular to the pivot axes 56, 57 and a theoretical intersection above the upper page 30 of the ski 2 is formed.

The recesses 79 to 82 or the corresponding indentations in the ski body, when projected onto a vertical plane pointing in the longitudinal direction - arrow 26 - have lateral boundary surfaces 99 to 102, with a theoretical crossing line of the lateral boundary surfaces 99, 100;

101, 102 in relation to a vertical direction lies below the pivot axes 56, 57 or below the anchoring elements 54, 55. The recesses 79 to 82 are thus continuously expanding starting from the tread 27 in the direction of the upper side 30, so that in relation to the longitudinal direction - arrow 26 - free spaces between the legs 17 to 20 and the inner boundary surfaces 99 to 102 of the recesses 79 to 82 are formed are, the relative movements between the ski 2 and the legs 17 to 20 of the support member 20 allow. In order to avoid icing of the free spaces between the legs 17 to 20 and the inner boundary surfaces 99 to 102 of the recesses 79 to 82, they can be filled with an elastic filler 103, e.g. a foam-like filler, which is a certain

Resilience behavior and is comparatively easy to deform. Likewise, the remaining free spaces between the bearing pins 52, 53 and the recesses 50, 51 in the legs 19, 20 can be filled with an elastic filler 104 in order to prevent ice and snow from being stored.

The injection of the filler 103, 104 into the remaining free spaces of the recesses 79 to 82 is preferably carried out after the mounting process of the support element 3 on the ski 2.

The anchoring elements 54, 55 can either be integrated directly in the manufacture of the sandwich element 7 or inserted between the individual layers, or they can also be fixed in the ski body after the manufacture of the ski 2. For this purpose, the bolt-like anchoring elements 54, 55 are to be pressed or driven into the through bores 61, 62 in the ski 2. Especially when the anchoring elements 54, 55 are subsequently inserted into the ski body, they have the radially protruding projections 63, 64, with which the pull-out strength of the anchoring elements 54, 55 is increased, since these projections 63, 64 are about the Cut through holes 61, 62 and anchor accordingly.

After the anchoring elements 54, 55 are fixed in the ski body, the support element 3 can be attached to the ski 2 in a simple manner. For this purpose, only the two halves of the support element 3 or the support element parts 11, 13 are on the bearing pins 47, 48; 52, 53 and to connect the two support element parts 1 1, 13 via the connecting device 12 to the one-piece support element 3. After activating the connecting device 12, the support element parts 11, 13 or the legs 17 to 20 slide off the bearing pins 47, 48; 52, 53 excluded.

The inner surfaces 91 to 94 of the legs 17 to 20 preferably lie against the comparatively hard, lateral boundary surfaces of the core 8 and / or the upper flange 67 and / or the lower flange 68 with as little play as possible.

5, 6 a further training variant of the sports device 1 or the ski 2 according to the invention is shown, the same reference numerals being used for parts already described above. The embodiment according to FIGS. 5, 6 can optionally represent an independent, inventive design of the sports device 1 or the ski 2.

Here, the support element 3 is formed in one piece and in turn is mounted in the recesses 79 to 82 in the ski body via the legs 17 to 20 formed in the corner regions of the plate part 32. The support element 3 is preferably formed by an extruded or continuously cast profile with a U-shaped cross section, on which the central region 16 of the support element 3 is reworked to form the four legs 17 to 20. In particular, those protruding from the central plate part 32 Legs removed in the central region 16 of the profile, so that the relatively narrow legs 17 to 20 are formed in the end regions 14, 15. The one-piece, one-piece support element 3 is in turn coupled to the ski 2 via the joint connection 44 and via the joint and guide device 49. The anchoring elements 54, 55 of the articulated connection 44 and the articulation and guide device 49, which are firmly connected to or integrated in the sports device 1, are formed by hollow cylindrical bearing bushes 105, 106. A longitudinal central axis of the bearing bushes 105, 106 runs essentially parallel to the running surface 27 and transversely to the longitudinal direction - arrow 26 - of the ski 2. These bearing bushes 105, 106 extend between the boundary surfaces 95, 96 shown in FIGS. 2 and 3; 97, 98 of the recesses 79, 80; 81, 82. The end faces of the hollow cylindrical bearing bushes 105, 106 preferably close flat with the boundary surfaces 95, 96; 97, 98, so that the recesses 79 to 82 machined into the ski body, with the support element 3 removed, do not detach from the various bearing parts between the support element 3 and the

Ski 2 are penetrated or do not protrude into them. The distance between adjacent legs 17, 18; 19, 20 is again chosen such that it is flat and as free from play as possible at the boundary surfaces 95, 96; 97, 98 of the recesses 79 to 82 are present. The bearing bushes 105, 106 representing the anchoring elements 54, 55 are fixed rigidly and immovably in the ski body. The deviation-resistant positioning of the bearing bushes 105, 106 can in turn be increased by the projections 63, 64 projecting radially from the lateral surface.

To mount the support element 3 or the ski binding 6 on the sports device 1, only the support element 3 with the legs 17 to 20 is to be inserted into the recesses 79 to 82 and the connection is to be completed by means of two bearing bolts 107, 108. The cross-sectional shape of the bearing bolts 107, 108 is chosen such that they can be inserted into the bearing bushes 105, 106 with as little play as possible. A length of the bearing bolts 107, 108 is selected such that it is greater than the length of the bearing bushes 105, 106, in particular the length of the bearing bolts 107, 108 is chosen to be approximately twice the thickness 109 of the legs 17 to 20, so that the Legs 17 to 20 are at least partially penetrated by the bearing bolts 107, 108. The bearing bolts 107, 108 in turn form the bearing pins 47, 48; 52, 53, the diameter of which essentially corresponds to a diameter of the recesses 45, 46; 50, 51 in the legs 17 to 20 corresponds.

The bearing bolts 107, 108 are known from any of the prior art Secured against arbitrary falling out of the bearing bushes 105, 106 after the mounting of the support element 3. For example, it is possible to glue the bearing bolts 107, 108 in the bearing bushes 105, 106 or to press the bearing bolts 107, 108 into the bearing bushes 105, 106 by means of a corresponding fit and thus prevent them from falling out.

The central longitudinal central axis of the bearing bolts 107, 108 forms the pivot axes 56, 57 between the support element 3 and the ski 2. The pivot axes 56, 57 in turn lie on the neutral fibers - plane 58 - of the ski 2, so that the anchoring elements 54, 55 are largely stress-free embedded. The neutral fiber - plane 58 - runs, in relation to the cross section of the ski 2, again approximately in the center area and parallel to the running surface 27.

For absolutely tear-proof fastening of the anchoring elements 54, 55 or the bearing bushes 105, 106, this can be provided in the outer casing area with projections 63, 64 in the manner of thread turns, so that the bearing bushes 105, 106 into the ski body or into the through bore 61, 62 can be screwed into the ski body and are thus positively connected to the ski 2. A screw connection of the anchoring elements 54, 55 or the bearing bushes 105, 106 is preferably used for skis 2 with wooden cores. The bearing bushes 105, 106 with the threads arranged on the outer jacket allow, in particular, retrofitting of the anchoring elements 54, 55 in the ski body, namely after the through bores 61, 62 have been machined essentially parallel to the running surface 27 and transversely to the longitudinal direction - arrow 26 - of the ski 2 .

Through a detachable connection of the bearing bolts 107, 108 to the bearing bushes 105, 106, it is possible in a simple manner to arrange a wide variety of support elements 3 with different ski bindings 6 quickly and without tools on a specific ski 2 or to carry out a corresponding exchange without problems.

FIG. 7 shows another embodiment variant of the sports device 1 or ski 2 according to the invention with the anchoring elements 54, 55 designed to connect the ski 2 to the support element 3 within the ski body. In the exemplary embodiment shown, the same reference numerals are used for parts which have already been described above, the previous explanations correspondingly valid for the same parts. The cross-sectional view through the sports device 1 or the ski 2 with the integral support element 3 fixed thereon for holding the ski binding is a sectional view through the bearing points on the ski 2 in the end regions 14, 15 of the support element 3, ie the anchoring elements 54 and 55 largely identical in each case in the end region 14 and in the end region 15 of the support element 3 integrated in the ski body. In the following description, only the front anchoring element 54 is referred to

Here, the anchoring element 54 consists of a piston-cylinder arrangement, at least one cylinder 110 being formed with two pistons 111, 112 guided therein. The cylinder 110 is designed in particular as a hollow cylinder 1 13 or as a sliding bush 1 14 for the pistons 111, 1 12. The cylindrical pistons 111, 112 are aligned in the sliding bush 1 14 in such a way that their longitudinal central axes 115, 116 form the pivot axis 56 and lie in the neutral fibers - plane 58 - of the ski body. The two pistons 111, 112 are axially adjustable with respect to their longitudinal central axes 115, 116 in the sliding bush 114, i.e. the pistons 11 1, 112 are guided by the sliding bush 114 in such a way that they can be moved towards one another and apart from one another in the direction of their longitudinal central axes 115, 1 16, but are held as immovably as possible in the other spatial directions.

At least the end regions of the two pistons 111, 112 which face away from one another have a circular cross section and form the bearing journals 47, 48 for the support element 3. The pistons 111, 112 preferably have a circular outline throughout, based on their cross section. Of course, however, it is also possible to cross-section the facing end regions, i.e. the regions following the bearing journals 47, 48, e.g. to be rectangular and accordingly to provide rectangular guide bores 117, 118 in the sliding bush 114.

The mutually facing end regions of the bolt-like pistons 11 1, 1 12 guided in the sliding bush 1 14 preferably have heads 1 19, 120 which prevent the pistons 1 11, 112 from falling out of the sliding bush 114. A cross-sectional dimension of the heads 119, 120 at the mutually facing ends of the pistons 111, 112 is chosen to be larger than a diameter of the bearing pins 47, 48 in the end regions distant therefrom. A corresponding guide recess 121 is assigned to the heads 1 19, 120 in the central region of the sliding bush 114, an extension 122, 123 being formed in each case at the transition from the guide recess 121 into the two guide bores 117, 118, which detects the movement of the pistons 111, 112 from the Sliding bush 114 limited in cooperation with the heads 119, 120 formed thereon.

The pistons 111, 112 are pushed under the action of a spring-elastic pretensioning device 124, in particular a compression spring 125, in the initial or rest state of the anchoring element 54 into their greatest possible distance from one another. The elastic prestressing device 124 thus causes the two pistons 11 1, 112 to be displaced into the most distant position, in which case the bearing pins 47, 48 protrude from the end regions 126, 127 of the sliding bush 114 or the bearing pins 47, 48 the end regions 126, Tower over 127.

In particular, the anchoring element 54 forms a releasable connection device 128 between the ski binding or the support element 3 for the ski binding and the ski 2, which can be activated and / or deactivated without tools. This connection device 128, which can only be operated manually, is designed in the manner of a preferably lockable snap lock, which enables an immediate and largely automatic connection of the ski binding to the ski 2 as well as a corresponding disassembly thereof.

The sliding bush 114 is preferably formed in two parts, the parting plane preferably being formed in the central region or in the region of the central guide recess 121, in order to be able to insert the two pistons 111, 112 with the heads 119, 120 into the sliding bush parts and around the pretensioning device 124 to be able to attach between the two heads 119, 120. The two parts of the sliding bush 114 are then connected via a connecting device, e.g. via a threaded arrangement 129, assembled to form a one-piece sliding bush 1 14. Of course, it is also possible to connect the connecting device by any other positive connections or by non-positive connections, e.g. by gluing, by welding or by a corresponding press and / or shrink fit between the two sliding bush parts.

The anchoring element 54, which comprises the pistons 111, 112, the sliding bush 114 and the spring-elastic pretensioning device 124, is integrated in the ski body in such a way that it cannot be pulled out, its end regions 126, 127 at least a partial area of the boundary surfaces 95, 96 of the recesses 79, 80 or indentations in the ski body form for inserting the legs 17, 18 of the support element 3. The anchoring element 54 is embedded between the individual layers of the ski 2, in particular, this is arranged between the upper flange 67 and the lower flange 68 and is partially enclosed by the filler 69 of the ski 2. The absolutely deviation-resistant mounting of the anchoring element 54 in the ski body can optionally be increased by the projections 63, 64 designed in accordance with the preceding descriptions or figures. Such an embedding of the anchoring element 54 in the ski body preferably takes place directly during the manufacture of the sports device 1 or the ski 2.

In addition, it is also possible to provide a threaded arrangement 130 on the outer jacket of the anchoring element 54. This thread arrangement 130 has a relatively large pitch and relatively high thread flanks in order to be able to subsequently insert the anchoring element 54 into an already manufactured ski 2. In this case, a through bore 61 connecting them is provided between mutually opposite recesses 79, 80, into which the anchoring element 54 with the threaded arrangement 130 can be screwed in in a simple manner and is thereby anchored in the ski body in a manner which prevents it from being torn out.

To connect the support element 3 to the ski 2 via the anchoring element 54, the recesses 45, 46 are arranged in the legs 17, 18 with a cross section corresponding to the bearing journal 47, 48. These recesses 45, 46 can be designed as a blind hole or as a through hole in the legs 17, 18.

To mount the support element 3 on the ski 2, only the pistons 111, 112 have to be pushed into the sliding bush 114 against the action of the elastic pretensioning device 124, so that the bearing pins 47, 48 are at least flat with the end regions 126, 127 of the sliding bush 114. Thereupon, the supporting element 3 with the legs 17, 18 can be inserted into the recesses 79, 80, and if the guide bores 117, 118 overlap or are aligned with the recesses 45, 46, the pistons 111, 112 are in particular by the elastic pretensioning device 124 by the compression spring 125, moved apart so that the bearing bolts 47, 48 engage in the recesses 45, 46 and produce the articulated connection 44 and also the articulation and guide device 49 in the rear end region of the support element 3.

The support element 3 can be coupled to the ski 2 in a simple manner by means of such anchoring element 54 and is connected to the ski in a high-strength manner. For the automatic or tool-free coupling of the support element 3 to the ski 2, link paths 131, 132 can be provided on the legs 17, 18, which enable the support element 3 to be snapped onto the ski 2 automatically and without hindrance. These slide tracks 131, 132 are formed by beveled planes on the legs 17, 18, the pistons 11 1, 112 automatically into the when the support element 3 is placed on the ski 2 and when a pressing force acting in the vertical direction is applied to the ski 2 Drive the sliding bush 114 and then, when it overlaps with the recesses 45, 46, protrude again from the sliding bush 114 and engage in the recesses 45, 46. Such an anchoring element 54 or such a design of the support element 3 thus enables the support element 3 with the ski binding to be mounted on the ski 2 without any tools. Accordingly, any support elements 3 with any ski bindings can be clicked onto a specific ski 2 in a simple manner or clipped on.

For a possible disassembly of the support element 3 from the ski 2, the recesses 46 can be provided as through holes through which the pistons 111, 1 12 or the bearing pins 47, 48 by pushing back into the sliding bush 114 out of engagement with the legs 17, 18 of the support element 3 can be brought. The support element 3 can therefore be uncoupled at any time if required by pushing the pistons 111, 112 or the bearing journals 47, 48 into the sliding bush 114 using suitable means. The recesses 45, 46 for mounting the support element 3 on the ski 2 can then preferably be optionally closed with a stopper 133 in order to prevent the ingress of ice or snow.

In addition, it is also possible to design the pistons 111, 112 without the heads 119, 120 if the recesses 45, 46 in the legs 17, 18 are designed as blind holes through which the extension movement of the pistons 111, 112 from the sliding bush 114 is limited. In particular, it is also possible with such a design to limit the pistons 1 1 1, 1 12 by means of plugs 133 which can be screwed into the recesses 45, 46 from outside in the extension movement from the sliding bush 114. Such plugs 133 are preferably screwed into the legs 17, 18 and hold the pistons 11 1, 112 in such a way that on the one hand they engage in the recesses 45, 46 and on the other hand they are also guided in the sliding bush 114. By removing the plugs 133 from the legs 17, 18, at least one piston 111, 1 12 can then be removed, and thereby the support element 3 can also be detached from the ski 2.

Furthermore, it is possible for the anchoring elements 54, 55 to be integrated into the ski body. Bearing bushes 105, 106 - as can be seen in particular from FIG. 6 - to form, which preferably opposite recesses 79, 80; 81, 82 via their inner guide hole, which is designed to receive and hold a preferably continuous bearing pin 107, 108 or also to receive two pistons 111, 112. The support element 3 is then placed on the sports device 1 such that the recesses 45, 46; 50, 51 are aligned with the inner bearing bores of the bearing bushes 105, 106, whereupon the bearing bolts 107, 108 can be inserted and connect the support element 3 to the ski 2 in an articulated manner. At least one of the mutually opposite recesses 45, 46; 50, 51 can be formed as a blind hole-like recess that limits at least one axial displacement movement of the bearing bolts 107, 108. After the bearing bolt 107, 108 has been inserted, the recess 46; 51 can be closed with the plug 133 or the plug 133 can be inserted into the recess 46; 51 are screwed in, so that falling out of the bearing pin 107, 108 is excluded. The bearing bolts 107, 108 are preferably fixed largely immovably in the axial direction by screwing or inserting the plug 133.

Regardless of the design shown, it is of course also possible to assign the pistons 11, 112 to the legs 17, 18 and to make them extendable and retractable from them, and therefore to extend and retract the legs 17, 18

Bearing journals 47, 48 to be assigned to a corresponding sliding bushing 114, which is integrated in the ski body and can optionally also be formed as a blind hole-like recess. Such a training would represent an equivalent training to the previously described embodiment.

The preceding description is not limited to the design of the anchoring element 54 in the front end region of the support element 3, but can of course also be transferred in a corresponding manner to the anchoring element 55 assigned to the rear end region by assigning corresponding reference numerals.

8 and 9 show a further embodiment variant of the sports device 1 or of the support element 3, which is connected to the ski 2 and supports the ski binding 6, in the manner according to the invention. Here, the same reference numerals are used for parts already described above, and previous descriptions are analogously applicable to the same parts with the same reference numerals.

Here, the support element 3 is essentially over its entire longitudinal extent in cross-section essentially U-shaped, that is, the leg plates projecting from the central plate part 32 essentially at right angles extend continuously over the entire length of the plate part 32 forming the support surface 21 for the ski binding 6 or for the foot of the user Legs 17, 18 projecting from sides of the plate part 32; 19, 20 thus also extend over the central region 16 of the supporting element 3. In the mounting region of the supporting element 3 on the ski 2, the shape of the legs 17, 18; 19, 20 corresponding, continuous recesses 79, 80; 81, 82 arranged, in which the legs 17, 18; 19, 20 of the support element 3 can be used such that the outer surfaces 85, 86; 87, 88 terminate essentially steplessly or flush with the side surfaces 89, 90 of the side cheeks 83, 84. Front ends 134, 135 of the support element 3 preferably form an acute angle with the support surface 21, ie the end surface regions of the support element 3 in the end regions 14, 15 extend, starting from the running surface 27, in the direction of the support surface 21, or are conical at Side view - according to Figure 8 - V-shaped boundary edges of the legs 17, 18; 19, 20 based on the longitudinal direction - arrow 26 - of the ski 2 is formed. The recesses 79, 80; 81, 82 in the longitudinal side areas of the ski 2 are selected larger than the surface dimensions of the continuous legs 17, 18; 19, 20, so that between the boundary edges of the legs 17, 18; 19, 20 and the boundary edges of the recesses 79, 80; 81, 82 a free space is formed, which allows a largely unhindered deformation of the ski 2 with respect to the support element 3. Thus, in particular between the front ends 134, 135 and the boundary surfaces 99, 100 and also between the running surface 27 facing longitudinal edges 136, 137 of the legs 17, 18; 19, 20 and the lower boundary surface of the recesses 79, 80; 81, 82 open spaces

138, 139 are formed which, when the ski 2 is deformed, permit a largely free mobility with respect to the rigid support element 3 and therefore in particular represent a compensation margin.

Of course, it is also possible to fill the free spaces 138, 139 with a filler which has a comparatively easy deformability and prevents ice and snow from becoming stuck in the free spaces 138, 139. Transversely to the longitudinal direction - arrow 26 - of the ski 2, the support element 3 is largely immovable relative to the ski 2. This can be achieved, in particular, by the inner surfaces 91 to 94 resting against the boundary surfaces 95 to 98 of the recesses 79 to 82 to a large extent without play. The support element 3 with the ski binding 6 is supported on the ski 2 via the anchoring elements 54, 55 integrated in the ski body, or is connected to the ski 2 via these. The bolt-like elements 65, 66 assigned to the end regions 14, 15 are preferably integrated into the ski body during the manufacture of the ski 2. A longitudinal extension of the bolt-like elements 65, 66 corresponds approximately to the width of the ski 2 in the assembly area for the ski binding 6, so that the bearing pins 47, 48; 52, 53 into the recesses 79, 80; 81, 82 protrude or protrude beyond the boundary surfaces 95 to 98 of the recesses 79 to 82. The bearing pin 47, 48; 52, 53 are corresponding recesses 45, 46; 50, 51 assigned in the legs 17 to 20. The recesses 45, 46; 50, 51 are worked into the leg plates in a slot-like manner starting from the boundary edges of the legs 17 to 20. Longitudinal central axes 140, 141 of the slots 45, 46; 50, 51 run essentially at right angles to one another when viewing a side region of the support element 3.

50 runs e.g. the longitudinal central axis 140 of the recesses 45, 46 is essentially parallel to the running surface 27, whereas the longitudinal central axis 141 of the further slot-shaped recesses 50, 51 is oriented essentially perpendicular to the running surface 27 or perpendicular to the support surface 21. The dimensions of the slot-shaped recesses 45, 46 are selected such that the support element 3 is guided on the ski 2 with as little play as possible in the vertical direction via the bolt-shaped element 65, but is relatively displaceable in the longitudinal direction - arrow 26 - of the ski 2. The dimensions of the further slot-shaped recesses 50, 51 in the end region 15 are selected such that the support element 3 is fixed immovably in relation to the longitudinal direction - arrow 26 - of the ski 2. The support element 3 is supported via the recesses 45, 46; 50, 51 with respect to a vertical direction each rigidly on the bearing journal 47, 48; 52, 53 from.

The slot-shaped recesses 45, 46; 50, 51 are preferably worked into the legs 17 to 20 of the essentially U-shaped profile by means of a separate machining process, the recesses 45, 46 extending from the front end 134 of the support element 3 in the longitudinal direction of the support element 3 into the legs 17, 18 incorporated or milled. The slot-shaped recesses 50,

51 in the end region 15 of the support element 3 are machined or milled into the legs 19, 20 starting from the longitudinal edges 136, 137 perpendicular to the support surface 21. Due to the previously described design of the support element 3 and the recesses 45, 46; 50, 51 is this in a simple manner via the bearing pins 47, 48; 52, 53 mountable on ski 2. To mount the support element 3 with the ski binding 6 on the ski 2, the end region 14 must first be put into active connection with the ski 2 and then the end region 15 must be put into active connection with the bolt-shaped element 66. For this purpose, only the journals 47, 48 are inserted into the recesses 45, 46 and subsequently the recesses 50, 51 are brought into engagement with the journals 52, 53 or the end region 15 is placed on the bearing journals 52, 53.

For secure connection of the support element 3 to the ski 2, at least one recess 50, 51 is assigned a locking element 142 which can be operated by the user of the sports device 1 and which optionally blocks an opening 143 of the recesses 50, 51. When the blocking element 142 is deactivated, the opening 143 of the recesses 50, 51 is released, as a result of which the bearing pins 52, 53 can be inserted into the recesses 50, 51 or removed therefrom. The blocking element 142 can subsequently be activated by the user of the sports device 1, as a result of which the opening 143 is closed and a separation of the support element 3 from the bearing pins 52, 53 is prevented. When the blocking element 142 is activated, the end region 15 of the support element 3 is connected in an articulated manner to the sports device 2, translatory movements between the end region 15 of the support element 3 and the ski 2 being largely prevented.

In the exemplary embodiment shown, the locking member 142 is formed by a locking bolt 144 which can be displaced in the longitudinal direction - according to arrow 26. The locking bolt 144, which can be displaced by a user 145 of the user of the sports device 1, can be displaced in a guide bore 146 in at least one leg 19, 20 of the support element 3 in the longitudinal direction of the support element 3. The locking bolt 144 of the locking member 142 is preferably pushed via a spring-elastic pretensioning device 147 into that end position in which lifting of the support element 3 from the ski 2 is prevented. This spring-elastic pretensioning device 147, which is preferably formed by a compression spring 148, is used to hold the locking bolt 144 in the end position in the rest or normal state in which the opening 143 of the slot-shaped recess 50, 51 is closed. When the locking bolt 144 is moved by means of the handle 145 counter to the force of the pretensioning device 147, the end region of the locking bolt 144 facing away from the compression spring 148 is removed from the recess 50, 51, as a result of which the opening 143 of the recess 50, 51 is completely released and the support element 3 be lifted off the trunnions 52, 53 can. Thereupon, the bearing devices 22, 23 in the front end region 14 of the support element 3 can also be released and the support element together with the ski binding 6 can be removed from the ski 2.

A possible displacement path of the locking bolt 144 is selected to be at least the same size as a protrusion of the locking bolt 144 from the guide bore 146 receiving the compression spring 148 in relation to the locking position of the locking member 142. The longitudinal axis of the guide bore 146 is essentially perpendicular to the longitudinal central axis 141 of the recess 50, 51 .

The guide bore 146 is preferably machined from the end 135 in the longitudinal direction of the support element 3 in the legs 19, 20 and crosses the slot-shaped recess 50, 51. The locking bolt 144 is against the handle 145, which can preferably be screwed to the locking bolt 144, against Falling out of the guide bore 146, which runs essentially parallel to the running surface 27, the handle 145 protrudes radially from the locking bolt 144 and the displacement path of the locking bolt 144 is defined for the handle 145 via a slot-like guide track 149. The longitudinal extent of the guideway 149 runs parallel to the longitudinal central axis of the guide bore 146 for the locking bolt 144. In the end regions of the guideway 149 for the handle 145, as indicated schematically, a branch in the guideway 149 running perpendicular to the displacement path of the locking bolt 144 can be used be provided, which allows the locking bolt 144 to be fixed at the respective position of the branch by reaching behind with the handle 145. In particular, by radially rotating the locking bolt 144 at the respective positions at which such a locking lug or branch is formed in the guideway 149, a hooking of the handle 145 with this locking lug is possible, as a result of which the locking bolt 144 is held in the respective position. When the handle 145 is pivoted back into the guideway 149 again, the locking bolt 144 is automatically pushed into the locking position via the pretensioning device 147. In this locking position of the locking bolt 144, a locking lug or a branch can also be provided in the guideway 149, which prevents the locking bolt 144 from being moved automatically against the spring force into the release position of the locking member 142. The combined, translational and rotary movement of the locking bolt 144 via the handle 145, which is predefined via the guide track 149, can be implemented with or without the action of a pretensioning device 147. The adjustment movements of the locking member 142 are similar to the adjustment movements of the breech of firearms.

The preceding description thus again forms a releasable connecting device 128 between a ski binding 6 or between a support element 3 for a ski binding 6 and a ski 2, which can also be activated and deactivated in a very short time by any user or layperson, and thereby the usual one , to be carried out by experts to assemble the binding using screw connections.

The two anchoring elements 54, 55 are in turn each arranged in the neutral zone or in the neutral layer - plane 58 - of the ski body, which is formed in the ski body under bending stresses directed perpendicular to the running surface 27. The anchoring elements 54, 55 can in turn be provided with projections 63, 64 for highly rigid fixing in the ski body, which extend essentially parallel to the running surface 27.

The support element 3 is preferably formed from an extruded profile made of aluminum, aluminum alloys, plastics or fiber-reinforced plastics with high bending strength and torsional rigidity. A locking member 142 is preferably assigned to each side cheek 83, 84 of the ski 2, which connects the support element 3 on each longitudinal side to the bearing pins 52, 53 so that it cannot be lifted off and thereby increases the torsional rigidity of the support element 3 or the entire sports device 1.

As can be seen in particular from FIG. 9, the indentations or the recesses 79 to 82 for the legs 17 to 20 of the support element 3 can be limited directly by the material of the hard outer shell 70, i.e. the recesses 79 to 82 in the ski body are already formed during the manufacture of the ski 2 by a one-piece shell 70 with corresponding indentations in the mounting area for the support element 3, thereby providing a ski structure which is uniformly covered by the shell 70 and which prevents liquids from penetrating into the Avoids chikers reliably.

Of course, it is also possible to achieve optimal water tightness for recesses 79 to 82 machined into the ski body after the manufacture of the ski 2 by subsequently coating their surfaces with a waterproof and / or elastic coating, such as lacquer. 10 shows another embodiment variant of an anchoring element 54, which is designed for the subsequent fixing of the same in the ski body and is used, for example, to hold a support element according to FIG. 8 on a ski. This bolt-shaped element 65 has in the central area on its outer circumference the threaded arrangement 129 and in the end areas related to its longitudinal direction a bearing journal 47, 48 is formed with a circular cross-section. In the front ends of the bolt-shaped element 65, blind-hole-like latching elements 150 with a polygonal cross-section can be formed, via which the bolt-shaped element 65 can be connected to a corresponding tool and can be rotated, wherein the latching element 150 can absorb a relatively high mechanical torque. The latching element 150 can have, for example, a square or hexagonal cross section, and the tool can be formed, for example, by an Allen key, via which the corresponding torque can be transmitted to the bolt-shaped element 65. The bolt-shaped element 65 can thus be coupled with a corresponding tool via this latching element 150 and screwed into a correspondingly prepared through hole in the ski body via the thread arrangement 129. The through hole extends from one side cheek of the ski to the opposite side cheek and runs essentially parallel to the tread and transversely to the longitudinal direction of the ski. A diameter of this through hole is selected such that the threaded arrangement 129 of the bolt-shaped element 65 engages in the ski body and, after screwing, holds it in the ski body in such a way that it cannot be pulled out.

FIG. 11 shows a further embodiment variant of a largely fully automatic connection device 128 between the ski binding or the support element 3 for the ski binding and the ski 2. In addition, a further embodiment of the locking member 142 on the connection device 128 to prevent the support element 3 from being detached arbitrarily from the ski 2 shown. Here, the locking member 142 includes a pawl 151 which is pivotally mounted about an axis 152 which runs parallel to the pivot axis 57 of the bearing pin 52. In the locked position of the locking device, the locking pawl 151 engages behind the surface area of the bearing pin 52 assigned to the opening 143 of the recess 45. This pivotally mounted locking pawl 151 is preferably in the normal state via the pretensioning device 147, which is preferably formed by a compression spring 148 the locking position is pushed, in which the bearing pin 52 is engaged behind by the locking lug 153 of the pawl 151 and thereby fixes the support element 3 immovably relative to the bearing pin 52, but rotatory movements around the bearing pin 52 or around the pivot axis 57. The pawl 151 is preferably provided with the handle 145, which allows a comfortable pivoting of the pawl 151 against the action of the pretensioning device 147 about the axis 152, the locking lug 153 then being moved out of the region of the recess 50 and thus the support element 3 from Ski 2 releases.

The angle enclosed by the locking lug 153 between its boundary edges is preferably less than 90 ° or the locking lug 153 is formed at an acute angle, so that when the pawl 151 hits the bearing journal 52, the latter is automatically pivoted counterclockwise, for example, and after complete insertion of the Bearing pin 52 in the recess 50, the pawl 151 springs back automatically and thus the locking member 142 is automatically placed in the locked state. The formation of such a pivotable pawl 151 with an acute-angled locking lug 153 which engages behind the bearing pin 52 in the locked state thus enables the support element 3 to be fully automatically locked onto the ski 2, the support element 3 simply being clicked onto the ski 2. This fully automatic "click-in system" for the support element 3 with the ski binding for fixing on the ski 2 can of course also be used in all of the exemplary embodiments described above.

In the locked state of the locking member 142, a locking edge 154 of the locking lug 153 engaging behind the bearing pin 52 extends essentially at right angles to the longitudinal central axis 141 of the slot-shaped recess 50 and thus blocks the opening 143 thereof.

If necessary, the handle 145 or the pivotable pawl 151 can also be assigned locking means which preclude unintentional pivoting of the pawl when the sports device 1 is in operation.

The pivot axes of the axis 152 and the pivot axis 57 of the bearing pin 52 lie approximately on the longitudinal central axis 141 of the recess 50 or in the extension thereof.

12 and 13 show a further exemplary embodiment of the ski 2 according to the invention or of the sports device 1 according to the invention, the same reference numerals being used for parts already described above. Here, the support element 3 is also formed in several parts, in particular in two parts, the separating and / or joining area 35 running transversely to the longitudinal direction - arrow 26 - of the ski 2 or of the support element 3 approximately in the central area 16 thereof. The support element parts 11, 13 thus formed are in turn positively connected to one another in the separating and / or joining area 35 via a connecting device 12, in particular via a telescopic guide arrangement 155, and thus form the support element 3. The guide arrangement 155 enables a relative displacement of the two support element parts 11 , 13 in the longitudinal direction - arrow 26 - to each other and apart. In the other spatial directions, the two support element parts 11, 13 are fixed immovably to one another via the guide arrangement 155. The guide arrangement 155 formed in the exemplary embodiment shown in the central region 16 of the support element 3 between the two support element parts 11, 13 can be formed by any guide designs known from the prior art between two profile parts. For example, the support element part 11 can be designed such that it at least partially encompasses the support element part 13 on the outside and thus the support element part 13 can be pushed into and out of the support element part 11. Furthermore, as shown schematically, the support element part 13 at the end area facing the support element part 11 can have a guide extension 156 with a circular or polygonal cross section, which can be inserted into a corresponding guide recess 157 in the second support element part 11 with a corresponding cross section. The coupling parts 4, 5 of the ski binding 6 are each supported in a longitudinal guide device 158, 159 in the two end regions 14, 15 of the support element 3, which are related to the longitudinal direction - arrow 26 - of the ski 2.

The longitudinal guide devices 158, 159 hold the coupling parts 4, 5 on the support element 3 and thereby allow an adjustment thereof in the longitudinal direction - arrow 26 - of the ski 2 relative to the support element parts 11 and 13. In particular, the coupling part 4 is on the support element part via the longitudinal guide device 158 11 stored and optionally in the longitudinal direction - arrow 26 - adjustable relative to this. Analogously to this, the coupling part 5 is mounted on the support element part 13 via the longitudinal guide device 159 and can be adjusted in the longitudinal direction relative to the support element part 13 - according to arrow 26 - guided by the longitudinal guide device 159. The longitudinal guide devices 158, 159 thus allow the coupling parts 4, 5 to be adjusted in the longitudinal direction - according to arrow 26. In the other spatial directions, the coupling parts 4, 5 are largely immovably fixed. The coupling part 4, which is embodied in particular as a toe of a safety ski binding, is connected via a connecting member 160 to that in particular as an automatic heel unit of a safety ski binding trained coupling part 5 connected. The connecting member 160 connecting the two coupling parts 4, 5 can be formed, for example, by a connecting rod or a connecting band in a rigid or flexible design. However, the connecting element 160 is in particular designed to be strain-resistant, so that the coupling parts 4, 5 which are connected to one another via the connecting element 160 are held at the distance from one another determined by the connecting element 160. Optionally, the connecting member 160 can be made length-adjustable via an adjusting and / or locking device 161 in order to be able to change the distance between the coupling parts 4, 5 and thus to be able to adapt the ski binding 6 to different shoe sizes in a simple manner.

At least one coupling part 4 or 5 can be fixed immovably via the adjusting and / or locking device 161 relative to the respective support element part 11 or 13. In the exemplary embodiment shown, the coupling part 4 or the front jaw is optionally fixed with the support element part 11 in its relative position to the support element part 11 via the adjusting and / or locking device 161. The adjusting and / or locking device 161 has an actuating element 162, by means of which the coupling part 4 can be fixed in relative positions to the support element part 11 in relation to the longitudinal direction - arrow 26 - so that it is fixed immovably at the respectively desired position when the locking device is activated. The coupling part 5 is motionally connected to the coupling part 4 via the connecting member 160 and remains freely floating in the longitudinal guide device 159. Via the adjustment and / or locking device 161, the user of the sports device 1 can thus change the relative position of the entire ski binding 6 relative to the ski 2 or to the support element 3, the distance between the two coupling parts 4, 5 corresponding to the shoe size being determined by the expansion-resistant connecting member 160 remains unchanged. The actuating member 162 interacts with a locking pin or the like, which, when the actuating member 162 is adjusted, optionally connects the coupling part 4 to the supporting element 3 or its longitudinal guide device 158 in a manner fixed against movement.

The support element part 11 comprises the legs 17, 18 which are directed from the support surface 21 in the direction of the underlying ski 2 and which are spaced from one another at a distance corresponding to the width of the ski 2. The end regions of the legs 17, 18 facing the ski 2 are articulated to the ski 2 via the bearing devices 22, 23. The articulated connection 44 in the end region 14 of the supporting element part 11 with the ski 2 comprises connecting elements in the exemplary embodiment shown 163, which are formed in particular by a pair of fastening screws 164, 165 which can be screwed into the anchoring element 54 or 55 integrated into the ski body.

The anchoring element 54, 55 extends continuously between the two side surfaces 89, 90 of the side cheeks 83, 84 of the ski 2. Accordingly, the ends of the anchoring elements 54, 55 are flush with the side surfaces 89, 90 of the ski 2. The legs 17, 18 lie with their inner surfaces 91, 92 over the full area on the side cheeks 83, 84 and on the end faces of the anchoring element 54, 55. To produce the articulated connection 44 between the support element part 11 and the ski 2, the connecting elements 163, in particular the fastening screws 164, 165, each penetrate one leg 17, 18 via the recesses 45, 46 and are rigid with the end regions of the anchoring element 54, 55 and secure against tearing connected. The fastening screws 164, 165 screwed or screwed in over the side cheeks 83, 84 of the ski 2 transversely to the longitudinal direction - arrow 26 - and essentially parallel to the running surface 27 into the two anchoring elements 54, 55 spaced apart in the longitudinal direction - arrow 26 - form the journals 47, 48 for the articulated mounting of the support element part 11. The fastening screws 164, 165 are fixed against rotation after the fastening of the support element part 11 and, as said, form in one

Screw head facing shaft part, the journal 47, 48 from. The shaft part of the fastening screws 164, 165 preferably has a larger diameter than the threaded section of the fastening screws 164, 165 facing away from the screw head. The screw heads of the fastening screws 164, 165, in cooperation with the threads, allow the legs 17, 18 to fit snugly on the side faces 89, 90 of the ski 2 and prevent the legs 17, 18 from sliding off the bearing pins 47, 48.

In the front end region 14 of the support element 3, the legs 17, 18 form a pair of legs and in the rear end region 15, which is related to the direction of travel - arrow 26 - the legs 19, 20 likewise form a pair of legs, each extending to the underlying ski 2 and when the support element 3 is in place, bear directly against the side cheeks 83, 84. The anchoring elements 54, 55 assigned to the pairs of legs and integrated in the ski 2 each lie in the neutral zone or in the neutral layer - plane 58 - of the ski 2 if it is subject to bending stresses directed perpendicular to the running surface 27. Furthermore, the anchoring elements 54, 55 are arranged on a common anchoring layer 166 integrated in the sandwich element 7. This plate-shaped anchoring layer 166, which receives or connects the anchoring elements 54, 55, is oriented with its two large flat sides essentially parallel to the running surface 27. A longitudinal extension of the anchoring layer 166 runs parallel to the longitudinal direction - arrow 26 - approximately over the entire length of the support element 3 or over the entire binding assembly area of the ski 2. The anchoring layer 166 is in the neutral layer or in the neutral fiber plane 58 - The ski 2 arranged. The neutral layer of the ski 2 - plane 58 - runs parallel to the tread 27 over the entire length of the ski 2, which is considered to be a composite material, and is oriented essentially parallel to the tread 27 of the ski 2, provided that the latter is subjected to bending stresses directed perpendicular to the tread 27.

A difference to the exemplary embodiments described above is that the two pairs of legs or respectively the legs 17, 18 and the legs 19, 20 in the two distal end regions 14, 15 each have a joint connection 44 on the side cheeks 83, 84 are connected to the ski 2 in an articulated manner and the longitudinal compensation device required for free shapability of the ski 2 is formed directly on the support element 3, in that it comprises at least two support element parts 11, 13 which can be displaced relative to one another via a guide arrangement 155 directed in the longitudinal direction - arrow 26 to stand by each other. The guide arrangement 155 acting in the longitudinal direction - arrow 26 - is thus realized via at least two support element parts 11, 13, the two support element parts 11, 13 each being articulated with the ski 2 via a joint connection 44 each with a cross-section to the longitudinal direction - arrow 26 and pivot axes 56, 57 aligned essentially parallel to the running surface 27 are connected to the ski 2.

Instead of arranging the guide arrangement 155 in the central region 16 of the support element 3, it is also possible to arrange both coupling parts 4, 5 of the ski binding 6 on only one support element part 11 and thus to provide the guide arrangement 155, for example in the end region 15 of the support element 3. In this case, the connecting member 160 can then be omitted and the two coupling parts 4, 5 can be held directly on the one supporting element part 11 or carried by the latter. The longitudinal compensation via the guide arrangement 155 can then be carried out by the relative displacement of the support element part 13 relative to the support element part 11, for example in the rear end region 15 of the support element part 13. If necessary, it is also possible to reinforce the bearing devices 22 to 25 via support cams 167 to 170. These support cams 167 to 170 protrude from the inner surfaces 91 to 94 of the legs 17 to 20 or from the underside 31 of the support element 3 and form a linear support surface on the upper side 30 of the ski 2. An additional support cam 167 to 170 is therefore provided Support of the support element part 13 is achieved on the top 30 or on the upper cover layer or shell 70 of the ski 2. The linear contact surfaces between the ski 2 and the support cams 167 to 170 arranged on the support element 3 are achieved by support bodies with an arcuate outer surface, the surface of the ski 2 or the top layer of the ski 2 tangential to the outer surfaces of these support cams

167 to 170 runs. The contact surface is arranged essentially vertically above the pivot axes 56, 57. The support cams 167 to 170 result in a direct, low-loss power transmission from the support element 3 to the running edges 71, 72 of the ski 2, since these transmit the force effect directly to the running edges 71, 72 via the legs of the shell 70. Impairments of the articulated connection 44 between the support element 3 and the ski 2 are negligible with appropriate dimensioning or with correspondingly soft support cams 167 to 170, but nevertheless result in a stabilization of the connecting device between the support element 3 and the ski 2 as well as an instantaneous introduction of force into the ski 2 and vice versa.

The anchoring elements 54, 55 have a cross-section, i.e. viewed transversely to the longitudinal direction - arrow 26 - of the ski 2, a polygonal, e.g. square cross-section, but can also assume circular or any other cross-sectional shape. The anchoring elements 54, 55 can in turn in the core 8 of the

Skis 2, which can be made of wood or other core building materials, are integrated or the anchoring layer 166 receiving the anchoring elements 54, 55 is fixed in the ski core.

If necessary, the plate-shaped anchoring layer 166 passes through the block-like anchoring elements 54, 55 via slot-shaped openings with a corresponding cross-section arranged in them, so that the distance between the two anchoring elements 54, 55 from one another can be adjusted by simply shifting them on the reinforcing layer 166 before embedding different lengths of support elements 3 can.

In summary, it can be stated that the support element 3 for the Ski binding 6 is supported in each of its end regions 14, 15 on the anchoring elements 54, 55 or anchoring layers 166 integrated in the ski body and arranged in the neutral zone - plane 58 - thereof, or is connected to them. Furthermore, the support element 3 for receiving a plurality of coupling parts 4, 5 of the ski binding 6 in the decentralized regions, approximately corresponding to the length of the shoe, is fastened to the side cheeks 83, 84 by the ski 2.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the sports device 1, this or its components have been partially shown to scale and / or enlarged and / or reduced.

The object on which the independent inventive solutions are based can be found in the description.

Above all, the individual, in FIGS. 1, 2, 3, 4; 5, 6; 7; 8, 9; 10; 11; 12, 13 shown form the subject of independent, inventive solutions. The relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
