Description

Adapter for a holding means, which is intended for fastening a recessed light in an opening, or holding means or recessed light with such an adapter

The invention relates to an adapter or a holding means or a recessed lamp according to the preamble of claim 1, 2, 15, 17 or 22.

A construction worker is set up to install a construction opening of a construction body. In most cases, the built-in body is a wall or ceiling with a built-in opening, in which the recessed luminaire can be recessed. In order to obtain a closure of the edge of the opening, known recessed luminaires in many cases have a collar-like protruding edge part that covers the edge of the opening.

In such cases, in which the body of the building is a suspended ceiling, there are various systems for holding the ceiling, which is mostly composed of flat ceiling elements, and the recessed luminaire. For this purpose, a known system has horizontal support rails which are located in the area of a dividing joint between two ceiling elements and, as a visible system, reach under the two ceiling elements with support legs arranged on both sides or are arranged as a concealed system and z. B. Intervene on the narrow side open recesses of the ceiling elements. Furthermore, it is also possible to hang the ceiling elements on the support rails located above by means of band-shaped fastening elements. The opening in the construction can correspond to the width of the ceiling elements, so that the opening in the construction is formed by omitting a section of a ceiling element. Such a recessed light is described and shown, for example, in DE 195 20 177 AI. Depending on the system or system manufacturer or for the purpose Z The most favorable division of the ceiling dimensions into modules there are module widths of different sizes for the ceiling elements and the spacing of the mounting rails from each other. This leads to installation difficulties of the luminaire, because luminaires of a certain type are manufactured with the same overall width dimension.

When installing a recessed luminaire, in many cases there is a need to adjust the height of the recessed luminaire, which can be an overall adjustment or a partial adjustment in the sense of a tilting movement. In the known configuration specified at the outset, the abutments of the holding means can be continuously adjusted in height. In the known embodiment shown in FIG. 1 from DE-19520177, it is necessary to loosen a clamping screw, to adjust the abutment vertically and then to tighten the clamping screw again. In the known embodiment shown in FIG. 16 of DE-19520177 AI, a vertical adjusting screw is to be rotated, which adjusts the abutment in a vertical guide.

These known designs are difficult to handle and / or complicated and expensive to manufacture.

The invention has for its object to find a solution that allows an adaptation of the holding means and / or the recessed light to Embauoffungen different cross-sectional sizes and / or to different heights of the Embaukorpers.

This object is achieved by the features of claims 1, 2, 15, 17 or 22.

In the configurations according to the invention according to claims 1, 2, 15, 17 or 23, an adapter is provided with a gap-reducing part and / or a spacer part, which adapts m and 7 or transversely to the plane of the installation opening and thus to the cross-sectional dimension of the installation opening and / or about right angled to different constructions or suspensions of the built-in body, the ceiling or the wall.

In the embodiment according to the invention, this enables an adapter which can be connected to the holding means in a position on the outside of the holding means by a holding element and which has a gap-reducing part, the outer side surface of which forms a positioning puddle which lies opposite the edge of the opening thereby ensuring the specified position of the recessed luminaire in the recessed opening, so that the recessed luminaire cannot slip sideways in the recessed opening. The outer surface of the adapter at the level of the installation opening forms a step dimension running in the width direction with the outer surface of the holding means, which corresponds to a large difference between two different installation openings.

The arrangement can be such that, in the smaller installation opening, the holding means with an outer surface as the delimiting surface forms a positioning surface which interacts with the opening edge, which is predetermined by the fact that the outer surface of the holding means takes into account an assembly movement play at the opening edge of the installation opening located. In the case of a larger installation opening, the outer surface of the holding means is at a laterally outward distance from the edge of the installation opening, this difference in width being filled in by the gap-reducing part of the adapter. This is achieved by the fact that the outer surface of the spacer, when the adapter is attached to the middle of the holder, is located on or near the opening edge of the opening and thereby forms the positioning surface, which m connection with the opening edge causes a lateral displacement of the recessed light m of the opening by a stop at the opening edge prevented.

In the variant contained in claim 1, the adapter is suitable for adapting to different or desired altitudes. In this configuration, the upper end of the di- stamped part a stop that interacts for vertical positioning with the body or holding rails holding it.

In the case of both solutions according to claims 1 and 2, it is possible to provide a plurality of adapters which differ from one another in terms of the width dimension of their gap-reducing part or in terms of the height of their spacer portion and thereby enable the desired adjustment in and / or across the plane of the installation opening .

Features are contained in the subclaims which lead to simple configurations of small or space-saving and inexpensive to manufacture construction methods and which further simplify and improve the width and / or height adjustment. For height adjustment, it is possible to adjust the spacer to the desired height by reaching the desired installation height. Reaching can be simplified and facilitated in that e.g. there are material tapering on the spacer formed by notches, by cutting, simplifying.

In the embodiment according to the invention, the height is adjusted in m steps with little effort simply by repositioning the adapter. This configuration is also characterized by particular simplicity and easy-to-use construction.

If the adapter is detachable, it is possible to

Reconstruct the luminaire so that it fits the corresponding smaller opening.

In the case of elongated luminaires such as fluorescent tubes, it is possible to arrange the adapters on one or both sides with respect to the vertical long-medium plane of the recessed luminaire. In both cases, the advantages described above can be achieved. In the case of a one-sided arrangement, there is a somewhat laterally offset arrangement of the recessed light in the opening in the recess, but this is irrelevant if a central arrangement is not absolutely necessary. On the other hand, if the adapters are arranged on both sides, there is an arrangement for the recessed luminaire centered in the associated mounting opening.

When installing a recessed luminaire, ensure that the recessed luminaire is securely connected to the edge of the recessed opening, as loosening in the fastening can result in noise from vibrations or rattling of the recessed luminaire. Loosening in the attachment can occur due to long-term effects and material loss.

The invention is further based on the object to find em means or to design a recessed light so that loosening in the attachment is prevented or harmless.

This object is achieved by the features of claim 22,

In this configuration according to the invention, a spring element is arranged as an elastically effective clamping part between the support sections of the holding means and the embau opening edge, which can be elastically bendable or elastically compressible and is preferably connected or connectable to the associated support section by a quick-locking connection or plug connection. As a result, the attachment is carried out with a clamping effect that elastically compensates for the loosening described in the attachment and acts with a permanent prestress on the edge of the installation opening. As a result, loosenings in the fastening that are difficult to avoid are not only prevented or rendered harmless, but vibrations and rattling noises are also avoided in the desired manner. The invention and further advantages which can be achieved by means of preferred exemplary embodiments and drawings are explained in more detail below. It shows

The main parts of the E construction light 1 are a base part 2, a light distributor 3 attached to it, which is formed here by a diffuser (opal disc or perforated plate), a reflector 4 without a so-called grid or a reflector 4 with a grid, holding means 5 for detachable holding the emba luminaire 1 in an emba opening 6 of a body 7 receiving the emba luminaire 1, e edge part 8 for the closure of the emba luminaire 1 at the edge of the emba opening 6, e operating device 9 and associated components for the electrical power supply of the emba luminaire 1 and one or two sockets 10 for at least one lamp 11. In technical terms, the distributor 3 and / or the reflector 4 is also referred to as light carrier optics.

In the case of the present embodiment, in which the emba luminaire 1 has an elongated design which is set up for one or two straight tubes as lamps 11, the base part 2 is formed by a plate or profile, in particular made of metal, for example sheet steel, and thus by the profiling stabilized. In the present exemplary embodiment, the profile has a U-shaped cross section with an approximately horizontal web 2a and legs 2b, 2c bent laterally therefrom. In the end rich the legs are laterally protruding projections are provided, which are formed here by rounded bends in the form of beads 2d.

The present light distributor 3, which has two curved rare reflectors 3a, is connected to the base part 2 by a releasable latching device 12. Locking springs can be used for this purpose, each of which engages behind a locking edge. In the present embodiment, snap springs 13 in the form of rod or leaf springs with latching noses 14 are formed on both outer sides of the rare reflectors 3a in the axial end regions, which engage behind the lateral projections or the beads 2d in an elastically locking manner and because of rounded or oblique insertion and export sections are elastically bendable over the beads 2d, the light distributor 3 being pulled elastically or resiliently against the edge of the installation opening 6 with its preferably embossed edge part 8 due to the rounded or inclined design surfaces.

The holding means 5 are formed by four support legs 16 which are identical to one another but are arranged on both sides with respect to the vertical longitudinal center plane 15 of the construction light 1 and are arranged opposite one another, in the case of an elongated construction light 1 four pieces in the end regions thereof. The support legs 16 bridge an existing construction gap between the edge of the construction opening and the construction light, wherein they are supported in the region of the edge.

Each of the mutually identical support legs 16 is part of a holding device 21 which has a support bracket 24 with an approximately horizontal support leg 24a attached to the base part and an approximately vertical support leg 24b, abutment 25 for the edge of the opening opening at the lower end of the support leg 24b 6 protrudes outwards, which is formed by a preferably integrally bent abutment leg 24c of the support leg 24b. Above the abutment 25 is em Holding part 26 m of an upright sliding guide 27 is mounted approximately vertically displaceably on the support leg 24b and has the shape of a holding leg 26a projecting outward from the sliding guide 27. The holding part 26 can be freely displaced in the sliding guide 27 between a lower fastening position and an upper release position and can be locked in the lower region of the sliding guide 27 by a locking device generally designated 28. The sliding guide 27 can be formed in that the holding part 26 surrounds an upright slot of the support leg 24b in the region of its guide end 26b or encompasses the support leg 24b, which is preferably made of flat aterial material, and is guided on the support leg 24b.

The arrangement can be such that be one in

Fig. 1 right counterclockwise upward rotation of the holding part 26, this automatically clamps in the sliding guide 27. Such a clamp connection can be formed by the effective length a (FIG. 4) of the holding part 26 being a multiple of an approximately vertical support or handle gripping distance b in the region of the sliding guide 27, e.g. is about 4 to 10 times as large. Due to the torque exerted by the weight of the lamp 1 on the body 7 holding part 26, a tilting inevitably takes place in the region of the sliding guide 27, whereby a clamping connection 30 (FIG. 4) is formed, which is then when the holding part 26 em Spring part is under permanent clamping tension. This clamp connection 30 can thus form the locking device 28 or contribute to its effectiveness.

However, it is also possible to design the locking device 28 independently of a previously described clamping action.

In the upper area of the support bracket 26b, the sliding guide 27 has an inward-facing sliding guide section 27a, which extends in the area of an inwardly extending transverse section 24d of the support bracket 24b. This is it to possible, the holding part 26 a m Fig. 3 shown on the right

To move assembly position in which it is so far inward with respect to its mounting position and preferably protrudes upwards that the insertion opening 6 is located within its cross-sectional area during insertion and does not interfere with the installation.

A push rod 29 is used to move the holding part 26 between its fastening position and its release position. It engages in the area of the locking device 28 at the guide end 26b of the holding part 26 and extends downwards in its use position on the inside of the upright support leg 24b. The length of the push rod 29 is dimensioned so large that its lower end can be gripped comfortably in the release position of the holding part 26, preferably in the lower region of the support leg 26b. Preferably, the push rod 29 is dimensioned so long that in the release position of the holding part 26 its lower end projects beyond the abutment 25 downwards and can thus be gripped in a manner that is easy to handle in order to pull the holding part 26 into its fastening position.

3, both push rods 29 are in their position of use, but on the right in the release position and on the left in the holding position of the holding part 26.

Two support legs 16 arranged on both sides of the base part 2 are assigned a common support part 17 which extends approximately horizontally and transversely to the longitudinal plane 15 and is detachably connected at its ends to the associated support legs 16. A detachable fastening device, preferably m in the form of a latching device 18, is used for this purpose, which is integrated in particular in a plug-in socket. In the present embodiment, the support part has a U-shaped cross section with a support part web, which can be left out in the central area, and support part legs 17a angled upward therefrom, between which the approximately horizontal connecting section 24a can be inserted in the form of a pin. About the sales b Dungsabschmtt 24a is in the socket e formed in this way, vertically elastically resilient latching element 18a, which m snaps into a latching recess 18b, preferably on the upper side of the connecting section 24a. This latching can be designed in such a way that it can be overprinted with a certain amount of force for releasing the connection by pulling out the connecting section 24a. The latching device 18 at the other end of the support part 17 is designed and arranged in mirror image. The transverse section 24d is preferably connected to the connecting section 24a by an approximately vertical leg section 24g. The transition between the support leg 24b and the transverse section 24d is preferably rounded, the rounded section 24h extending to the central region of the transverse section 24d or also somewhat further.

The support bracket 24 is a stamped / bent part, which is preferably made in one piece. 8 shows the support angle as an elongated strip. The support bracket 24 has an upright central slot 32 forming the sliding guide 27, which begins at a distance from the abutment 25 and extends continuously to the transverse section 24d and preferably also the leg section 24g. A slit extension 32a can be provided in the area of the transverse section 24d, which possibly extends to the area of the curve 24h.

The push rod 29 is arranged on the inside of the associated support leg 24b of the holding means 5 and is pivotably connected to the holding part 26 by means of a hinge 41 with a hinge axis 41a in the existing plane, which extends vertically and in the longitudinal direction of the mounting luminaire 1 Joint axis 41a in the form of a connecting leg 40 is formed. Here, the push rod 29 can be pivoted between a horizontal clamping position directed towards one or towards the silk side and a downward loose position. In the approximately horizontal clamping position, the holding part 26 is by a clamping device 42, for example in the form of a cam arrangement, jammed on the support leg 24b, which automatically functions when the push rod 29 is swiveled up. The hinge 41 is suitable because of a hook-shaped configuration of the invention, leg 40, also the pivoting of the holding part 26 in its pushing mde upward position according _ä ß Fig. 3 aware afford right, namely a rotation about a horizontal and m the longitudinal direction of the lamp 1 extending axis of rotation.

In order to stabilize the holding part 26 in its release position, it is advantageous to provide a releasable connecting device, preferably in the form of a hooking device 51, between the push rod 29 and the support leg 26b, which prevents the holding part 26 of the sliding guide 27 from swiveling out and sliding down unintentionally. This can be done through a

Holding lug 52 in one part and a holding edge on the other part are formed, the release position of the holding lug 52 engaging behind the holding edge 53 in a form-fitting manner. In the present embodiment, the holding lug 52 is provided on the outer side of the push rod and is preferably formed by a cut-out and nose-bent tongue 54 which has a rounded or oblique flank 55 on the upper side in order to hook into its release position when the holding part 26 is moved with an obstacle in the way. The holding edge 53 is preferably formed by the lower edge 32c. The upper edge 32d of the slot can serve as a stop for limiting the movement of the holding part 26 m in its release position.

As can be seen from FIG. 3, the push rod 29 is angled through an acute angle W, preferably from approximately 10 to 15 ° in its central region, such that the lower shaft region 29a projects from the support leg 24b in the use position of the push rod 29. In the released position of the associated holding part 26 and the closed position of the hooking device 51, the shaft region 29a bears against the support leg 24b, the upper shaft region 29b diverging obliquely inwards (Fig. 3, right) and the holding part 26 m of a stop position in which it is inscribed _above resembled the edge of the mounting hole 6 inside ver ^¬ sets.

It is advantageous to use the above-described holding devices 21 m in connection with a holder of the base part 2 (FIG. 3) that can be swiveled up and down on the support parts 31. In such a configuration, the holding part 2 by two Ge ^¬ joints 61 is connected to the supporting parts 31st On the other L _ä long side is a releasable connecting device 57 for Hal ^¬ th of the base part 2 of the raised position m vorgese ^¬ hen, which are preferably attached by a latching device with egg ^¬ ner on YEARS _ö ring mount 31 spring 62 is formed having a latching edge on the base part 2, here the associated bead 2d elastically grips. Such an Embauleuch ^¬ te 1 is not only easy to install, but also a ^¬ electrical connection. For this purpose, the base part can be swung easily 2, wherein the fact befindli ^¬ che Betriebsgerat 9 reaches taken into a convenient accessible position, m the electrical connection work can be handling boyfriend ^¬ Lich carried _above leads. Then the base part is swiveled up and locked.

It is advantageous to assign a width adjustment device 65 to each holding part 5 or support leg 16, which enables the width of the construction light 1 to be adapted to a different width of the opening 6.

In the embodiment of Fig. 9, are versenen in the same or comparable parts have the same reference numeral, only a left-hand holding device 21 shown by the Embauleuchte 1 with a nozzle leg 16 and described, the ge ^¬ gen _ü berliegende, arranged in mirror image Holding device 21 or support leg 16 is formed in mirror image. This configuration is suitable, inter alia, for a so-called suspended ceiling 7, consisting of rows of ceiling elements 7a, which they reach under in the area of the dividing joints. the support rails 67 and suspension ropes 68 or corresponding elements are suspended from a support ceiling, not shown. The support rails 67 have the cross-sectional shape of an upturned T, and they therefore have a vertical web 67a, from the lower end of which support legs 67b protrude on both sides, which engage under the ceiling elements 7a from below. This is a visible suspension system.

With the module width M of the ceiling elements 7a, i.e. the center distance between one of the adjacent parting lines 66 is the smallest module width of several larger module widths that have become common practice. The module width M can e.g. Amount to 300 mm. As can be seen from FIG. 9, the built-in lamp 1 is designed such that the dimension d measured over the outer surfaces of the support legs 24b is adapted to the inner distance e of adjacent support rails 67, taking into account a build-in clearance, so that the built-in lamp 1 with the support legs 16 can be removed from below between the support rails 67. The inner distance e can also be the dimension of an opening 6 in which there are no support rails 67, as shown in FIGS. 1 and 3.

In the arrangement according to FIG. 10, in which a larger module width Ml or installation opening width is provided, for example a module width M of 312 mm, the width of the adaptation light 65 is associated with the adapter luminaire 65 with an adapter 71, which has a connecting device 72 for connecting the Adapters 71 to the holding means 5 and e spacer 73, which extends from a base part 74 of the adapter 71 pin-shaped upward and preferably has a rectangular or square horizontal cross-sectional shape. In the fastened position, the spacer 73 is located on the outside of the holding means 5, here on the support leg 24b, it preferably resting on the outside thereof. The width f of the spacer 73 is dimensioned so large that it takes into account the The construction game already mentioned fills the distance between the outer surface of the support leg 24b and the associated support leg 67b. As a result, the Embauleleuchte 1 is adapted to the next larger module width Ml.

The spacer 73 can perform two basic functions. For a width adjustment it is a reducing part 73a for the installation gap.

The exemplary embodiment according to FIG. 11, in which the same or comparable parts are provided with the same reference numerals, shows, for example, an opposite holding means 5 or support leg 16, an invisible support rod system being provided for hanging the ceiling elements 7a, in which the support rails 67 are located in the area of the dividing joints 66 are located above the ceiling elements 7a, which can have a box-shaped hollow cross section. In this embodiment, the ceiling elements 7a are suspended from the support rails 67 by means of thin support elements 68a, the support elements 68a being fastened to the narrow end faces of the ceiling elements 7a or engaging behind the undercuts provided thereon.

In this arrangement, the E luminaire 1 is adapted to an even larger module width M2 in that the adapter 71 with respect to the holding part 5 carrying it in a rotated position, e.g. is arranged here rotated by 180 °. The adapter 71 thus enables adaptation to a plurality of module widths here to three module widths M, Ml and M2. In this embodiment, either the outer surface of the holding means 5 or the support leg 24b or the spacer 73 of the support rail 67 or the edge of the installation opening 6 is arranged on or nearby.

The adapter 71 and its attachment to the associated holding means 5 are described in detail below. The connecting device 72 is preferably a plug-in connection with the adapter 71 and the plug-in connection points associated with the holding means 5, which can optionally be connected to one another in the sense of a plug-in socket. In the case of the present embodiment, the base part 74 is designed in a socket-shaped manner with a web part 74a and angled peripheral legs 74b in a C-shape such that it can be pushed onto the pin-shaped abutment leg 24c with little movement play or with a self-locking tension. The spacer 73 extends upwards from the upper side of the base part 74, it being arranged off-center both in the longitudinal direction and in the transverse direction of the mounting light 1, and is thus removed from the effective range of the holding part 26.

Because of its eccentric arrangement m of the transverse direction of the construction light 1, there are different adaptation dimensions g, gl between the side 74c, 74d of the base part 74 facing the holding means 5 and the side of the spacer 73 facing away from this side, the outer surface of which is a delimitation and positioning surface 73a in that it prevents displacement of the recessed light 1 of the opening 6 by a stop action. The installation dimension of the built-in lamp 1 results from the sum of the dimensions d + g or gl or d + gl or 2gl. The respective opposite holding means 5 is correspondingly designed and arranged in mirror image, so that no additional description is required.

. On the end faces of the base part facing the longitudinal direction of the emba luminaire 1, upward-facing lugs or angle pieces 75 are integrally formed, which result in hook-like formations and, on the one hand, to facilitate assembly when the adapter 71 is attached to the abutment leg 24c and / or to provide additional support for the associated ceiling element 7a can serve.

It is possible within the scope of the invention to design the adapter 71 in such a way that further intermediate positions in the existing range and thus further adaptation measures g to be realized. For this purpose, for example, pressure points can be formed in the area of the adjustment path of the guide 76 formed by the gripping of the abutment leg 24c, which can be manually overprinted with a small amount of force and thus result in traceable pressure points for setting the respectively desired adaptation dimension g. In the embodiment according to FIG. 14, in the area of the guide channel predetermined by the C-shape, at least one, in particular rounded, knob 77 is arranged on the guide channel wall, here in the end area of the surrounding leg 74b, which has a recess or one in the abutment leg 24c at one or more desired pressure points. Calotte (not shown) is assigned, which the knob 77 is able to snap into and can be overprinted by a certain amount of manual effort due to its rounded shape. In this way, desired adaptation positions of the adapter 71 in the region of its displacement path can be set, this setting being secured against undesired displacement due to the elastically overprintable pressure point.

A further adjustment position or intermediate position can also be achieved by at least one stop for the displacement, which can be bent or broken away, if necessary, and thus can optionally be deactivated. In the embodiment according to FIG. 13, such a stop 78 is formed by a stop leg 78a which projects from the web part 74a m and which can be bent or removed due to a bending or predetermined breaking point 81. In the embodiment according to FIG. 13, the stop 78 is arranged in the region of a recess 82 in the web 74a, the bending or

The predetermined breaking point 81 is arranged in the foot region of the angular leg 78a.

The adapter 71 consists of solid or preferably elastically bendable material, in particular plastic, which may be an injection molded part that, despite its relatively difficult design, can be produced easily and quickly. It is advantageous to assign a level adjustment device 85 to each support 16, which allows adjustment in the case of level differences of the body or the ceiling 7 in a stepless or em- or multi-stage manner. In a first embodiment, an em or multi-stage adaptation device 85 is provided. In this embodiment, one or more end sections 24k (FIG. 4) of the abutment leg 24c are connected to the rest of the abutment leg 24c by one or more material weakenings 86, so that the end section 24k can be bent up using a suitable tool, for example pliers. The material monitoring 86 can be formed by a groove 86a. In the case of such a level correction, the abutment 25 abuts the body 7 with the end section 24k.

In the adapter 71, the level adjustment device 85 is formed in that the spacer 73, which is designed in particular in the form of a pin, extends upwards as a high-spacer part 73b and consists of a material that can be cut off manually with scissors or cut off with pliers, in particular plastic. Material weaknesses 87 or predetermined breaking points are preferably provided at certain, in particular the same, height spacings from one another, here in the form of ring notches, which facilitate the lengthening both in terms of dimensions and in terms of force. The adapter 81 thus fulfills a width and / or level adjustment.

15 and 16, in which the same or comparable parts are also provided with the same reference numerals, the level adjustment device 85 is provided by an adapter 71 m in the form of a pin-shaped plug element 91, which is 25 m above the abutment which may be present a plug-in opening 92 of the support leg 24b can be inserted to such an extent that it projects beyond the support leg 24b and can thus cooperate with the support rail 67 as an abutment by engaging under the support rail 67 or engaging the end faces of the adjacent ceiling element 7a.

An advantageous embodiment of such a level adjustment device 85 is formed by a vertical row of holes 75 in the support leg 24b, whose hole e the plug element of corresponding cross-sectional shape and / or size and length can be inserted. In the present embodiment, the holes 92 of the row of holes merge into one another, so that the shape of a toothed slot results, to which the shape of the plug element 91 is adapted, the form-fitting mounting of the associated plug element 74 being ensured. The plug-in element 91 is preferably adapted to the shape of two mutually adjacent holes 92, including the free space between them.

In the event that small levels are to be adjustable, it is advantageous to provide, in addition to the first row of holes 92a, a second row of holes 92b, the holes 92 of which are preferably offset by half in height with respect to the holes in the first row of holes.

17 to 21, in which the same or comparable parts are provided with the same reference numerals, the adapter 71 is formed by an e-shaped or two-armed or by an angular or U-shaped spring element 95, the width of which is denoted by h and which is punched and bent from a flat strip 96 as a starting material. The spring element 95 is preferably made of spring steel and is made in one piece. It has a base web 97, from which one or two mutually opposite spring legs 98 extend divergently in a U-shape with bent ends.

In this embodiment, the connecting device 72 is formed by one or two shoulder gripping lugs 99 which grip the associated support leg 24a in the fastening position, preferably in adapted cutouts 101 in the horizontal support leg 24a. In the present embodiment the rear gripping lugs 79 protrude from the outside contact side 102 of the base web 97, whereby they are directed towards one another. The cutouts 101 are dimensioned larger with sufficient movement play than the rear gripping lugs 99, so that the latter can be inserted into the cutouts 101, engaging behind their inner edges 101a. The free ends of the rear gripping lugs 99 are preferably bent outwards at an angle or rounded, as a result of which insertion slants result. The connecting device 72 snaps into place by manually compressing the spring legs 98, the base web 97 being bent and the rear engaging lugs 99 being spaced apart from one another and thus the cutouts 101 can be inserted. When the spring legs 98 are released, they spring back and the rear gripping lugs 99 automatically snap behind the inner edges 101a em.

A plurality of rows, here two rows R, cutouts 101 are preferably provided, so that the spring element 95 can optionally be fitted to one or the other row. The assembly or disassembly can be carried out quickly and easily due to the existing quick-connect or plug-in connection. Due to the one-piece design, the spring element 95 can also be produced quickly and inexpensively in a simple manner. The rear gripping lugs 99 are preferably designed as tongues which are cut out and bent out by U-shaped incisions 103. In the area of the apex 104 between the base web 97 and the spring legs 98, cutouts 105 are preferably arranged which facilitate the bending and shaping in the apex 104. The spring legs 98 are each fork-shaped divided by an elongated slot 106 arranged in the middle or off-center, which extends to the vicinity of the associated apex 104. The longitudinal slots 106 diverge to their free outlet hm, preferably by an angle W of approximately 2 °.

This adapter 71 is also designed as a spacer 73 or reducing part 73a for adapting the width of the construction light 1 to Different internal distances e or corresponding dimensions of the installation opening 6 can be carried out. The split spring legs 98 allow additional width adjustments. If the spacer 73 or the spring element 95 has space overall in the construction opening gap, then its entire width can serve as a spacer, the outer side 98al of which forms a stop or boundary surface for the associated construction opening edge. This can be done when mounting the spring element 95 both in the first and in the second row of the cuts 103. If, on the other hand, the mounting gap between the installation opening edge or the associated support rail 67 is smaller, then the outer spring leg parts 98a are located under the associated ceiling part 7a or the support rail 67, while the inner spring leg parts 98b with their outer sides 98bl oil the spacer 73. By a central or external central arrangement of the longitudinal slots 106 with respect to the connecting device 72 on the one hand or by a central or eccentric arrangement of the connecting device 72 and the alignment of the longitudinal slots 106 with respect to the width h of the spring element 95, on the other hand, a step change in the installation width of the mounting light can be achieved 1 in that the adapter 71 or the spacer 73 is mounted by turning in the respective suitable arrangement, in which the outer sides 98al, 98bl of the outer or inner spring legs 98a, 98b have different width dimensions with respect to the inner distance e.

The spring element 95 can also serve a completely different purpose, namely that of integrating a clamping action m as a spring-elastic buffer or tensioning part into the fastening device of the construction light 1. The fastening is improved by this clamping action. The elastic clamping effect also exerts its holding function when the attachment yields due to long-term effects or material shrinkage. In this way, vibrations or rattling noises caused by loose fastening are avoided. HZ

In the embodiment according to FIG. 19, the spring element 95 is arranged essentially completely between the horizontal support leg 26a and the ceiling part 7a, no lateral centering or locking in the installation opening 6 being required, or the vertical support leg 26b being on or near of the installation opening edge. The spring element 95 only fulfills a spring or clamping function and no distance function.

In the arrangement according to FIG. 20, the spring leg parts 98a are located under the cover part 7a, while the inner spring leg parts 98b form spacer parts 73, which are located on or m near the edge of the construction opening and form boundary surfaces with their outer sides 98bl. As already in the arrangement according to FIG. 19, the spring part 95 can also be located in the outer or inner row R here.

The arrangement according to FIG. 21 shows the spring element 95 in the first fastening row R and a basic position according to FIG. 20, the outer spring leg parts 98a being arranged in a clamping manner under the mounting rail 67 and the inner spring leg parts 98b forming spacer parts 73.

The base web 97 is preferably somewhat concavely curved with respect to its contact side 102 or the blades 104 are bent out. As a result, the spring element 95 rests with spring tension on the support leg 24a, and a firm or clamping snap fit is achieved.
