Description

Locking parts

technical field

The invention relates to a latch for a linkage attachment to a window, door or the like.

Background technique

For locking windows, doors or the like, link attachments are used, on which locking elements are preset, at least on the closed (i.e. against the frame) sash or door, which engages in a mating in the lock. Normally, the connecting rod attachment is installed on the window or door leaf, and a plurality of locking pieces are usually fixed at corresponding positions on the window or door frame. In general, however, the opposite installation is also possible.

The linkage of the linkage attachment can be pushed in the direction of its longitudinal extension (this usually corresponds to the path of the groove (Falz) between the leaf and the frame) by means of an operating element (eg a window or door handle) , for thereby pushing the respective locking element connected to the link between different longitudinal positions. Such locking elements can be designed, for example, as pins and cooperate with respective associated locking elements to lock the leaf on the frame depending on the longitudinal position of the locking element. The different longitudinal positions of the locking elements differ not only in terms of their position but also in function, i.e. in a certain longitudinal position (e.g. locking position) the locking element cooperates with the locking element The flap that prevents closing is opened, and the flap that allows closing is opened in another longitudinal position (for example a swivel open position or a tilt open position).

In general, an elongated receptacle arranged along the longitudinal axis is provided on each locking part, and the receptacle is used for accommodating the attachment of the connecting rod in different longitudinal positions, which can be adjusted in the direction of the longitudinal axis. Moving, mating locking elements. This elongated receptacle is especially designed and mounted such that each locking element in the receptacle can be pushed between its different longitudinal positions. Thus, said longitudinal axis corresponds substantially to the direction of the displaceability of each locking element.

Transversely to the longitudinal axis, that is to say in a lateral (in particular substantially just perpendicular) direction with respect to the longitudinal axis, the locking element enables access from the elongated receptacle. Such a lateral movement of the locking element occurs when the leaf is closed or opened. The locking element can only be pushed between its longitudinal positions when the leaf is closed and thus arranged along the longitudinal axis. This pushing can take place, for example, via an actuating handle, wherein the handle is connected to the locking element via a linkage.

The elongated receptacle in principle allows the locking element to be moved along the longitudinal axis between its different longitudinal positions, however, it depends on whether the locking element can also be moved transversely to the longitudinal axis for opening or closing the leaf. at each longitudinal position occupied by the locking element. Because the function of the locking element is precisely to hold the locking element in a certain locked longitudinal position in the elongated receptacle, so that the window or door leaf cannot be opened. For this purpose, the elongated receptacle is limited transversely to the longitudinal axis by at least one stop which at least prevents the locking element from being moved out laterally when the locking element is in the locked longitudinal position. Elongated housing.

This elongated receptacle can, for example, have at its longitudinally extending end a U-shape or similar shape defined on three sides and open on a fourth side, wherein the longitudinal axis passes through the open side and the opposite closed side. As a result, the locking element can be moved through the opening side at least between one longitudinal position and another longitudinal position, wherein in one longitudinal position the locking element is located outside the U-shape and can thus be moved transversely to the longitudinal axis , while in the other longitudinal position, the locking element is located within the U-shape and is prevented from moving transversely to the longitudinal axis by the arms of the U-shape. This obstructing arm of the U thus forms the said stop.

In principle, however, other sides of the elongated receptacle need not be defined apart from the stop described. The so-called minimal locking element can also essentially consist of a single stop, for example a wall-shaped projection. As a result, the elongated receptacle is not materially bounded neither over its entire length nor on all its sides. This shows that the original functional definition of the elongated receptacle is that it constitutes an area of the locking element in which the individual locking elements of the link attachment, which are associated with the locking element, can be positioned differently in the direction of the longitudinal axis. to move between vertical positions.

In principle, the locking element can have a plurality of stops which block each locking element in a plurality of different longitudinal positions in order to prevent them from being moved laterally out of the elongated receptacle. In addition, at least one channel part can be provided, which releases the locking element in an otherwise reversed longitudinal position, so that it is moved laterally out of the elongated receptacle (and through which channel part, the locking element reverses Come over also just can even arrive in the elongated accommodation part). In which position on the longitudinal axis each stop or channel section on the latch is preset, which depends inter alia on which side of the leaf or frame the latch should be used and what the window or door should have. the way to open.

For example, for a window that can be swiveled about the vertical side and can be tilted about the lower horizontal side, the latch must lock the locking element on the lower horizontal side in order to both lock and tilt the opening leaf, but the locking element must be released for rotation Open the wings. In contrast, the locking element must lock the locking element on the upper horizontal side or the vertical side of the hinge distal end only for locking in the locked position, but the locking element must be released for pivoting and tilting open. For such a window, the locking element is thus in particular displaceable between a locked position, a swiveled open position and a tilted open position. The stop of the associated locking part is thus mounted such that the locking element is locked or released correspondingly for a lateral movement depending on the longitudinal position.

In known closures, depending on its longitudinal position, the locking element accommodated in the elongated receptacle can either be moved transversely to the longitudinal axis, or cannot be moved at all. However, in order to expand the function of windows, doors or the like, if the locking member locks the respective locking element in a certain longitudinal position to prevent it from moving laterally out of the elongated housing, it still allows the locking It is desirable for the tightening element to have at least limited lateral movement. This can be advantageous, for example, for achieving a secure tipping position in which the window or door is only tipped open a narrow gap, but the locking element is still held in the elongated receptacle of the closure. Ventilation can, for example, be achieved by means of such a tipped position, while the window or door is still protected, for example, against breakage.

Contents of the invention

It is therefore an object of the present invention to provide a locking element for a link attachment of a window, door or the like, which is suitable for locking the locking element of the link attachment in at least one defined longitudinal position of the locking element. The locking element prevents it from moving laterally out of the elongate receiving portion, while allowing the locking element to carry out limited lateral movement.

This object is achieved by the closure element according to the invention, and in particular by the fact that the closure element comprises a base element and an adjustment element movably supported thereon, wherein the elongated receptacle is arranged on the adjustment element In the above, the stopper is arranged on the adjustment member, and the adjustment member can move between the original position and the offset position relative to the base member transversely to the longitudinal axis, so that the locking element can be locked in the longitudinal position locked by the stopper limited lateral movement.

In other words, the locking part is not designed in one piece as usual, but consists of at least one base part and an adjusting part independent of it. In this case, the base part is designed in particular for fastening the closure to a window, door or the like, for which purpose it can have, for example, holes or other openings or receptacles for the fastening part. The adjustment member is movably supported on the base member, which enables the adjustment member to move between a home position and an offset position. Therein, this movement takes place in a direction transverse to the longitudinal axis, ie in a lateral direction with respect to the longitudinal axis. It is not excluded in this way that this mobility also has other directional components. The adjustment part can be displaced laterally, so that the locking element, which is already in the longitudinal position locked by the stop, can likewise be displaced in the lateral direction. However, the movability of the locking element is limited in this case. In particular, the locking element can be moved exactly together with the adjustment piece, so that its movability is limited on the one hand by the original position and on the other hand by the offset position of the adjustment piece.

In principle, this closure is very similar in size to conventional (in particular one-piece) closures, and the same locking elements of the respective linkage attachment can be used. This has the advantage that a conventional latch can be replaced in a simple manner by the latch according to the invention, thus supplementing the function of the safe tipping position. When the adjusting element of the locking element is in its original position, this locking element can even be designed substantially identically to conventional locking elements in construction. However, a functional distinction is achieved by the two-part design with the movable adjustment element, that is, in at least one defined longitudinal position of the locking element, its mobility transverse to the longitudinal axis is not completely controlled. blocked, but allowed with restrictions.

In order to enable the displaceability of the adjusting part relative to the base part to also enable a limited lateral movement of the locking element, it is especially important that not only the elongated receptacle is designed in the adjusting part, but also that the stop Also designed on the adjustment piece. As a result, the elongated receptacle and the stop are not fixed in position, but can be moved in a defined manner laterally to the longitudinal axis, so that the locking element accommodated in the elongated receptacle can also be moved in the same manner. Movement occurs.

Consequently, the basic locking function of the stop is not eliminated by the displaceability of the adjustment element. Rather, the stop thus continues to block the lateral movement of the locking element out of the elongated receptacle. That is to say, preferably, the locking element can only be moved laterally jointly with the elongated receptacle and the stop, so that the locking element does not leave the elongated receptacle. Furthermore, the lateral mobility of the locking element is limited. Beyond this limit, the window or door cannot be opened.

An undercut can be provided on the elongated receptacle in order to prevent the pin, which is designed as a mushroom head, from leaving the elongated receptacle in its radial direction. Since it is thus no longer possible to release the locking element from the latch by levering the leaf open, such an embodiment increases the security against theft. Since the locking element accommodated in the elongated receptacle does not leave the receptacle when the actuating part is displaced, the locking part according to the invention also maintains this advantage in the deflected position of the actuating part.

In addition to the functional blocking of the locking element against lateral movement out of the elongated receptacle, the stop can also be used as a movement locking point for the adjustment element to move from the initial position into the deflected position. Thus, for example, the adjustment element can be moved from the original position to the offset position by causing the locking element to be pressed laterally against the stop, thereby causing the adjustment element to move out of its original position and towards the offset position. Move in the direction of the shift position. This can be done, for example, by pulling the wings of a window, door or the like. However, it is also possible, for example, that the linkage attachment comprises a mechanism which, when adjusted to the safe tipping position (probably by rotating the handle of the window or door to a defined position), moves the wing of the window, door or similar from the The matching frame moves a gap. This can be achieved, for example, by means of a forcedly controlled shear.

The elongated receptacle is designed in the adjustment part, which means in particular that this space, which is intended to accommodate the mating locking element in different longitudinal positions, is at least partially in the region of the adjustment part, ie approximately also On the same plane as the (flat) adjustment piece. However, this does not rule out in principle that the elongated receptacle is also partially embodied in the base part.

According to a preferred embodiment, further stops are designed on the base part. By means of such a further stop, it is possible to lock the locking element in other longitudinal positions in order to prevent it from moving laterally out of the elongated receptacle. In contrast to the described (displaceable) stop which is embodied on the adjustment part and is thus displaceable together with the adjustment part, this other stop is formed on the base part. This other stop is thus fixed (immobile) and cannot likewise be displaced when the adjustment element is displaced. Thus, such other stops can be used, for example, to ensure the locking position of the locking element, in which the window or door leaf is to be locked in the closed position and the locking element is to be locked thereby against its lateral Move in the opening direction on the longitudinal axis.

According to a further development, said (movable) stop is preset on the first end of the elongated housing relative to the longitudinal axis, and the other (immobile) stop is preset on the elongated housing. on the second end of the head, the second end being on the opposite side of the first end. In this case, it is advantageous if the position of the stop corresponds to the different longitudinal positions of the associated locking elements. As a result, the locking element can be moved approximately along the longitudinal axis between a locking position for locking the window or door leaf and a safety tipping position for secure tipping of the leaf. Thus, the elongated receptacle formed in the closure extends along the interval defined by this locked position and the tipped position, wherein, at one end of this extension, a (movable) stop is mounted on the safety In the region of the tipping position, and at the opposite other end of this extension, a (immobile) further stop is mounted in the region of the locking position of the locking element.

Further defined longitudinal positions of the locking element can be preset between the locking position and the safe tipping position, such as a swivel open position and/or a tipping open position in which the locking element must be able to move laterally Leaving the elongated receptacle so that the leaf can be swiveled open, the locking element must also be able to move out laterally in the tilted open position (at least when the locking element is located on the distal side of the leaf or frame's tilting axis) Elongated housing.

Thus, according to an advantageous further development, the elongate receptacle is further delimited in a direction transverse to the longitudinal axis by at least one channel portion which releases the locking element for its lateral movement out of the elongate Nabu. Thus, this channel section can be defined precisely in such a way that no obstacles are provided in the region of the channel section which would prevent the lateral movement of the locking element out of the elongated receptacle (or conversely, laterally into the elongated receptacle). This channel portion can thus be formed, for example, by interrupting an otherwise continuous structure. Such a channel section can also simply be a free space, in particular a free space adjoining the adjacent stop.

In this case, the channel section is in particular designed between said (movable) stop and the (immovable) other stop. In particular, such an arrangement is suitably adapted to the sequence of the longitudinal positions of the associated locking elements from the locking position via the swivel open position and/or the tipping open position to the safety tipping position. Since the elongated receptacle is also formed in the adjustment part, preferably the channel section is formed on the adjustment part. Just as the elongated receptacle can also be partially formed on the base part, the channel section can also be partially formed on the base part. It is important here that neither the adjusting part nor the base part blocks the lateral movement of the respective locking element out of the elongated receptacle in the region of the channel part.

According to a preferred embodiment, the base part is arranged substantially in a first plane and the adjustment part is arranged substantially in a second plane, wherein the first plane and the second plane are parallel to said longitudinal axis, And towards the direction of the movability of the adjustment part, and the first plane and the second plane adjoin each other, so that the flat side of the adjustment part (lower, facing the leaf or frame provided with the locking part) rests against the base On the flat side (upper, facing away from the leaf or frame) of the seat part. These described planes are not (infinitely thin) planes in the mathematical sense, but flat spatial regions with a certain thickness. Preferably, the base part and the adjustment part are substantially flat.

The base part is arranged substantially in the first plane and the adjustment part is arranged substantially in the second plane, which also means that the flat extension of the base part or the adjustment part is substantially in the first plane or the second plane Inner extension. However, this does not exclude that certain parts of the base part or of the adjustment part extend out of the respective plane and, for example, also extend into the respective other plane, as long as the respective (flat) basic structure, in particular the majority of the structure , are set in their respective planes.

In this exemplary embodiment, the base part and the adjustment part each have flat sides, with which they bear against each other. Thus, the contact surface of the two flat sides can correspond exactly to the interface between the first plane and the second plane. Because the direction of the adjuster's mobility is parallel to these planes, when the adjuster is moved between its original position and the offset position, it does not move out of the second plane, but moves within the second plane . Nor can the base part and the adjustment part be pressed together perpendicular to these planes or separated from each other. More often than not, the flat side of the adjustment part slides advantageously on the flat side of the base part, so that a certain guidance of the adjustment part on the base part is thereby produced.

According to a further development of this embodiment, a further stop, for example the further stop described, is designed on the base part and extends in the second plane. The base part, which is arranged substantially in the first plane, therefore protrudes into the second plane via this further stop. Such an arrangement is advantageous if the adjusting part with the elongated receptacle and the (movable) stop is arranged in the second plane in order to be able to limit the The elongated receptacle, the other stop which is formed on the base part and thus does not move, must therefore also lie at least partially in the second plane. By extending in the second plane, the (immobile) further stop can also interact with the adjustment element, eg be used as a stop to limit the displaceability of the adjustment element.

On the basis of this development, optionally or additionally, the base part has at least one connecting element extending in the second plane for movably supporting the adjustment part on the base part, and /Or the adjustment part can have at least one connecting element extending in the first plane for displaceably supporting the adjustment part on the base part. In order to keep the flat side of the adjustment part abutting against the flat side of the base part, connecting elements can also be provided, which are designed on the base part and/or the adjustment part and extend in the plane of the respective other part . Here, they can cooperate with the respective other part, so that the adjustment part is movably supported on the base part, that is: on the one hand, it prevents the adjustment part from being loosened unintentionally from the base part, and on the other hand Movement of the adjustment member relative to the base member is enabled and preferably also defines a path and length of mobility.

According to an advantageous embodiment, the base part has at least one connecting projection, in particular in the form of a pin, and the adjustment part has at least one connecting rail, in particular in the form of an elongated hole. Alternatively, the exact opposite can be done, ie the base part has at least connecting rails, in particular in the form of slotted holes, and the adjusting part has at least connecting projections, in particular in the form of pins. In particular, the connection projection can be the above-mentioned connection element.

In this case, the connecting lug and the connecting rail are preferably designed in such a way that the connecting lug engages in the connecting rail, or that the connecting lug interacts with the connecting rail in some other way, which is suitable for connecting the base part and the adjusting part are connected to each other (in particular not separately) and/or are adapted to define the movability of the adjustment part relative to the base part. This can be realized particularly easily if the connecting projection is a pin which engages in a connecting track designed as an elongated hole. A corresponding deflection movement sequence of the adjustment element can be defined via the length and path of the elongated hole. In particular, two or more mating pairs consisting of connecting protrusions and connecting rails are preset on the locking part, thereby improving the support stability of the adjusting part on the base part.

According to a preferred embodiment, the adjustment element can be moved obliquely to the longitudinal axis. In other words, the (not necessarily straight) path of the displaceability of the adjustment element includes a directional component in the direction of the longitudinal axis. Thus, at least this adjusting element is not only movable perpendicularly to the longitudinal axis.

If the adjusting element is also moved in the direction of the longitudinal axis when it is moved from its original position into the deflected position, the elongated receptacle is thus also moved relative to the locking element accommodated therein, wherein The locking element remains in its longitudinal position. In this way, for example, one end of the elongated receptacle can be moved towards the locking element, so that the locking element is accommodated so-called deeper in the elongated receptacle and is thus very well secured therein. . This is particularly advantageous if, in a longitudinal position of the locking element that can leave the elongated receptacle laterally (for example, a swivel open position or a tipping open position) and the locking element is locked by the described (movable) stop The stroke between the closed longitudinal position (for example, dumping position) is so small that the locking element in this longitudinal position cannot be locked by the described (movable) stop over its entire longitudinal extension. By moving the adjusting part also in the direction of the longitudinal axis, the stop can be moved so-called further in front of the locking element, so that the locking element is locked particularly securely.

With regard to the oblique displaceability of the adjustment part, it is preferred that the direction of the displaceability of the adjustment part relative to the base part forms an angle of less than 90°, especially less than 60°, preferably less than 60°, with the said longitudinal axis. 40°-50°, especially preferably 45°. In particular, the adjustment element can be moved only at this angle, ie this displaceability has a straight path. Here, an angle of 45° is particularly advantageous if the movement of the adjustment part relative to the base part is caused by a force originating from the locking element and acting in the direction of the side. Because at an angle of 45°, a component of movement parallel to the said longitudinal axis can be obtained equally well both when the adjusting element is moved from the initial position into the deflected position and vice versa.

Irrespective of the specific path and/or angle of the movability of the adjustment element, preferably a (movable) stop is preset on the first end of the elongated housing relative to the longitudinal axis and the adjustment When the member is moved laterally into the deflected position, it also moves in the direction of the second end of the elongated receptacle, which is located on the opposite side of the first end. The movement of the adjusting element in this direction is such that the locking element locked by the (movable) stop moves further in the elongated receptacle in the direction of the first end and is therefore particularly securely locked. Locking, wherein said locking element does not change its longitudinal position when the adjusting member is moved. In this case, the first end of the elongated receptacle forms a stop for the locking element remaining in its longitudinal position and thus limits the displaceability of the adjustment element.

Furthermore, it is advantageous if positioning means, in particular mechanical and/or magnetic positioning means, are provided between the adjustment part and the base part to secure the adjustment part in the original position and/or in the deflected position. Such a positioning element can advantageously be such that a certain force threshold must first be exceeded before the adjustment element can be moved out of its original and/or deflected position. Alternatively or additionally, the positioning element can be used, by engaging the adjusting element in each position, for example due to an attractive or repulsive force, so that the adjusting element reaches the original position and/or the deflected position particularly reliably. A positioning element of this type helps to prevent an incorrect operation or an undesired (for example due to wind) closing of the leaf and thus increases the operating reliability of the closure.

In the following, the present invention will be further described by way of embodiment only with reference to the accompanying drawings.

Description of drawings

FIG. 1 shows a schematic view of an exemplary embodiment of a closure according to the invention.

Figures 2A to 2E show the embodiment shown in Figure 1 with locking elements provided, showing the adjustment of the locking element and the locking elements in different positions.

FIGS. 3A to 3C exemplarily show a simplified further embodiment of a locking element equipped with a locking element, wherein the adjusting element and locking element of the locking element are shown in different positions.

Detailed ways

The locking part 11 shown in FIG. 1 comprises a substantially flat base part 13 and a likewise substantially flat adjustment part 15 adjoining it. The base part 13 and the adjustment part 15 have an elongated structure extending along the longitudinal axis L, and substantially the same outer contour along the respective surrounding narrow sides 17, 17', so that the base part 13 and the adjustment part 15 The original positions of the adjustment members 15 shown in FIG. 1 are aligned with each other. Therein, the base part 13 is arranged substantially in a first plane (the lower plane according to the orientation in FIG. )middle. These two planes adjoin each other in the region of the interface 19 between the (upper) flat side of the base part 13 and the (lower) flat side of the adjustment part 15 .

In the center of the adjusting part 15 is provided an elongated receiving part 21, which is suitable for accommodating a locking element 23 in the form of a mushroom head pin matched with the locking part 11 (see FIGS. 2A to 2E), wherein the locking element 23 can be positioned at Inside the elongated receptacle 21 occupy different defined longitudinal positions, which differ from their position along the longitudinal axis L. As shown in FIG. For this purpose, this elongated receptacle 21 is generally designed in the form of an elongated hole in the adjusting part 15 .

This elongated receptacle 21 is not closed peripherally, but is open towards one side in the middle region. In this central region, the elongated receptacle 21 is thus delimited by a section via which the locking element 23 can be moved into or out of the elongated receptacle 21 transversely to the longitudinal axis L, if the locking element is located in the corresponding (central ) in the longitudinal position. In this respect, said portion constitutes the channel portion 25 . In the illustrated embodiment, depending on its length and position, the channel part 25 is unclamped in two different defined longitudinal positions, namely: a swivel open position and a pour open position, see FIGS. 2B and 2C . The element 23 is used to move it laterally out of the elongated receptacle 21 (as will be explained below). In this respect, at least functionally, this channel part 25 can also be regarded as a double channel part 25 or as two channel parts 25 directly following one another.

In the direction of the longitudinal axis L, the two sides of the channel part 25 are connected with stops 27, 29, which, like the channel part 25, define the elongated housing part 21 on the same side, but unlike the channel part 25, These stops prevent the locking element 23 from being moved laterally (in this lateral direction) out of the elongated receptacle 21 . The two stops 27 , 29 are arranged at the opposite ends 31 , 33 of the elongated receptacle 21 with respect to the longitudinal axis L. As shown in FIG. Wherein, the stopper 27 is designed on the adjustment member 15 and is located at the first end 31 of the elongated receiving portion 21, on the contrary, the other stopper 29 is designed on the base member 13 and is located at the elongated receiving portion 21 at the second end 33 .

The stop 27 on the adjustment part 15 is basically arranged on the second plane described, which also includes the rest of the adjustment part 15 as much as possible, while the other stop 29 on the base part 13 is from as far as possible. Starting from the first plane, possibly including the rest of the base part 13 , extends into the second plane. In this way, the further stop 29 can laterally delimit the elongated receptacle 21 which is substantially designed in the adjustment piece 15 (and thus in the second plane).

As at least visible on the other stop 29 of FIG. 1 , the stops 27 , 29 have an undercut 35 facing the elongated receptacle 21 . Corresponding undercuts are also designed on opposite sides of the elongated receptacle and at its border in the longitudinal direction in the region of the two ends 31 , 33 . In the longitudinal position, that is to say in the position where the locking element is located in the region of the first end 31 or the second end 33 of the elongate receiving part 21 and is prevented from moving laterally by the respective stops 27, 29, Due to its mushroom shape, the locking element 23 , which is designed as a mushroom pin, engages the adjacent undercut 35 from behind and is thus secured particularly securely. In particular, the locking element 23 is then unable to leave the elongated receptacle 21 axially relative to its mushroom shape. This increases the fracture resistance of the closure element 11 .

Two parallel elongated holes 37 are formed on the adjustment part 15, which have a straight course at an angle of 45° to the longitudinal axis L and extend almost over the entire width of the adjustment part 15 (transversely to the longitudinal axis L) . These elongated holes 37 form connecting rails in which connecting projections in the form of pins 39 on the base part 13 engage. The pins 39 extend into the adjustment piece 15 via the respective elongated hole 37 , so that they protrude (similarly and to the same extent as the other stops 29 ) into the second plane. The distal end of each pin 39 relative to the base part 13 has an enlarged diameter 41 in the shape of a mushroom head, through which the pin 39 can be non-detachably connected to the respective elongated hole 37 in the form of a rivet. The base part 13 is thus also connected to one another, preferably non-detachably, with the adjustment part 15 by means of the pin 39 interacting with the elongated hole 37 .

Wherein, the adjustment member 15 can move relative to the base member 13 , that is, it can move along a path defined by the cooperation of the pin 39 and the slot 37 . Corresponding to the orientation of the elongated hole 37 , the adjustment element 15 is movable at an angle of 45° to the longitudinal axis L between a home position as shown in FIGS. 1 and 2A to 2D and an offset position as shown in FIG. 2E . As a result, the adjusting element 15 can be displaced transversely to the longitudinal axis L, but wherein it is always also displaced parallel to the longitudinal axis L due to the elongated hole 37 arranged obliquely to the longitudinal axis L. Based on an angle of 45°, this offset transversely and parallel to the longitudinal axis L is the same every time.

Several views of the embodiment shown in FIG. 1 are shown in FIGS. 2A to 2E above a plane perpendicular to the extension of the base part 13 and the adjustment part 15 . Here, the adjustment element 15 is in its original position in FIGS. 2A to 2D , while it is moved in its offset position relative to the base element 13 in FIG. 2E . Furthermore, FIGS. 2A to 2E also differ from each other in the respective longitudinal positions of the locking elements 23 , which are associated with the closure element 11 , are accommodated in the elongated receptacle 21 and are designed perpendicular to the drawing plane. pins, especially mushroom head pins. The locking element 23 is part of a connecting rod attachment, not shown, via which the locking element is drive-connected in order to make it possible to move it (for example in relation to the rotational position of the operating handle) in the shown Move between defined vertical positions.

In particular, the locking element 11 can be fastened to the window frame or the door frame, while the connecting rod attachment is fastened to the window or door leaf. In principle, this arrangement can also be reversed. Wherein, the base part 13 of the locking part 11 is fixed on the frame (or wing leaf). For this purpose, the base part 13 has holes 43 (not shown) perpendicular to its plane of extension for fastening means, such as in particular screws. Along the longitudinal extension of the base part 13 , a total of three holes 43 are provided (see especially FIG. 2E ), which are advantageously evenly spaced apart.

The illustrated embodiment is especially designed to be mounted on the side of the window or door which does not constitute the tilting axis of the window or door leaf, but in particular on the side facing the tilting axis. In general, the locking element 23 is just accommodated in the elongated receiving portion 21 if the leaf and the frame, on which the locking member 11 and the linkage attachment are installed, are in close contact with each other, that is, when the leaf is closed. .

The longitudinal position of the locking element 23 shown in FIG. 2A can be, for example, the locking position of the locking element 23 in which other stops 29 lock the locking element 23 to prevent it from moving laterally out of the length. Shaped container 21. Since the other stop 29 is designed on the base part 13 (see FIG. 1 ), it is stationary, that is to say it is fixed in position relative to the frame (or leaf). As a result, the locking element 23 is locked against lateral movement relative to the longitudinal axis L. As shown in FIG. In this longitudinal position of the locking element 23 , the closed leaf cannot be opened, but is locked by the cooperation of the locking element 23 and the (immobile) further stop 29 . Such a locked position may for example correspond to a downwardly rotated position of a handle of a window or door (not shown).

FIG. 2B differs from FIG. 2A only in the longitudinal position of the locking element 23 , which is, for example, the rotationally open position. The distance (stroke) between the locked position ( FIG. 2A ) and the rotated open position ( FIG. 2B ) can be created, for example, by rotating the handle by 90° in a horizontal direction. In the swivel open position, the locking element 23 is located in the region of the elongated receptacle 21 that is laterally delimited by the channel section 25 . In the rotationally open position of the locking element, the channel part 25 releases the locking element 23 in order to move it laterally out of the elongated receptacle 21 so that the leaf can be (rotated) opened.

FIG. 2C differs from FIGS. 2A and 2B only in that the locking element 23 is in another longitudinal position, namely, for example, in the tip-open position. In FIG. 2C , the locking element 23 is also released by the channel portion 25 in order to be moved laterally out of the elongated receptacle 21 so that the leaf can be (tilted) opened. However, comparing Figures 2A to 2C, it can be seen that the stroke between the dump open position (Figure 2C) and the swivel open position (Figure 2B) is less than that between the swivel open position (Figure 2B) and the locked position (Figure 2A). The itinerary, especially exactly half that. The tipped-open position of the locking element 23 can thus be formed, for example, by turning the handle 45° upwards from the horizontal into a tilted position. This shows the difference from the conventional rotational position of the handle when the leaf is tipped open, in which the handle is generally vertically upwards.

By presetting such an oblique swivel position, a vertically upward swivel position is used for an additional defined longitudinal position of the locking element 23 , such as the safety tipping position as shown in FIGS. 2D and 2E . In this case, the travel between the safety tipping position ( FIGS. 2D and 2E ) and the tipping open position corresponds in particular to half the travel between the swivel opening position ( FIG. 2B ) and the locking position ( FIG. 2A ).

Due to the comparatively small stroke, the locking element 23 in the safety tipping position is initially ( FIG. 2D ) not locked over its entire longitudinal extension by the (movable) stop 27 arranged on the adjusting part 15 . In other words, the locking element 23 initially still partially protrudes beyond the stop 27 in the region of the channel section 25 . Nevertheless, the locking element 23 is already blocked by the stop 27 from leaving the elongated receptacle 21 transversely to the longitudinal axis L. As shown in FIG.

If, for example, by pulling the handle of the leaf or operating the mechanism that tilts the leaf away from the frame, the locking element 23 in this position is pushed in the direction of the (movable) stop 27, the locking element 23 is in the A force is applied to the stop 27 in a direction transverse to the longitudinal axis L. As shown in FIG. As a result, the adjustment element 15 is displaced from its original position in the direction of action of the force. Due to the joint action of the pin 39 and the elongated hole 37, the adjusting part 15 is guided on the base part 13, so that it is not only moved in the direction of force action (ie perpendicular to the longitudinal axis L), but also parallel to the The longitudinal axis L is moved so that it is moved obliquely to the longitudinal axis L (ie at an angle of 45° to the longitudinal axis L) as a whole. In this case, the elongated hole 37 is adjusted such that the adjustment element 15 is moved further away from the second end 33 of the elongated receptacle 21 of the (movable) stop 27 than in its initial position in the deflected position. direction to move.

Advantageously, the extent of the displaceability of the adjusting part 15 is limited according to the design of the connecting rail serving as the closed elongated hole 37 . In the offset position, therefore, an in particular maximum movement of the adjustment part 15 relative to the base part 13 takes place.

Because the locking element 23 is preferably not able to change its longitudinal position non-operatedly (but only by operating the handle or at least operating the linkage attachment), when the adjustment member 15 is in the original position ( FIG. 2D ) and deflected During a movement between the positions (FIG. 2E), the locking element 23 remains in the safe tipping position. In this case, however, as a comparison of FIGS. 2D and 2E shows, the locking element 23 in the safety tipping position is displaced laterally together with the adjustment element 15 . In this case, the movement of the locking element 23 is also limited due to the limited movement of the adjustment element 15 .

Despite the lateral movement, the locking element 23 remains in the elongated receptacle 21 so that the locking element 23 remains protected therein. In any case, due to the oblique movement of the adjustment member 15, the locking element 23 is locked relative to the adjustment member 15 in the direction of the longitudinal axis L (ie further in the second position of the elongated receiving portion 21 which is closer to the (movable) stop. The movement occurs in the direction of one end 31). As a result, the locking element 23 is pressed more deeply into the first end 31 of the elongated receptacle 21 so that it is held against the (movable) stop over its entire longitudinal extension and thus in particular securely. 27 lock. At the same time, the first end 31 of the elongated receptacle 21 serves as a stop for the locking element 23 , by which the displaceability of the adjusting part 15 and of the locking element 23 can be additionally limited.

2D and 2E, this two-part embodiment of the locking element 11 with the base element 13 and the adjustment element 15 movably supported thereon enables presetting in the elongated housing 21. A longitudinal position of the locking element 23 is provided in which the locking element 23 can be moved securely, but limited laterally, so that for example a closed window or door can be tilted open a gap. In this case, the size of this gap is defined by the extent of the displaceability of the adjustment part 15 relative to the base part 13 and is very small compared to the customary tipping open position. In this way, it is possible, for example, to realize a ventilation position of the wing leaf which is particularly well protected against breakage.

With regard to the protection against breakage, it is further important to reliably limit the displaceability of the adjusting part 15 and thus also of the locking element 23 so that the said gap cannot be unduly enlarged. Thus, it is possible to combine the already described co-actions used to limit the movability (that is: the co-action of the pin 39 with the elongated hole 37 and the co-action of the first end 31 of the elongate receiving portion 21 with the locking element 23 ) on the basis of other elements are additionally provided, which together serve as a stop and prevent the adjustment part 15 from being moved out of the deflected position.

For example, in the embodiment shown in FIGS. 1 and 2 , a corresponding stop 45 is preset on the side of the elongated receiving portion 21 opposite to the channel portion 25 and the stops 27 , 29 , and this corresponding stop is located on the adjusting part. 15 hits the (immobile) further stop 29 when it reaches the offset position and thereby additionally blocks further movement of the adjusting element 15 . In addition, the first end 31 of the elongated receptacle 21 can have a base 47 which extends from the second plane to a depression 49 in the first plane, which is designed as an indentation for the flat side of the base part 13 . Flat groove, the bottom of which meets the corresponding stop edge 53 of the recess 49 via the stop edge 51 when the offset position is reached.

In a similar manner, further stops can be provided between the base part 13 and the adjustment part 15 , which also help to prevent movement out via the home position in the opposite direction. For this, for example, the bottom 47 can once again be made to interact with the recess 49 via a further stop edge and a further corresponding stop edge (not shown), and/or a (immobile) The other stop 29 cooperates with a further corresponding stop 45' of the adjusting element 15 in its original position (see FIG. 2A ).

In order to enable the adjusting part 15 to be pressed back from the offset position back to the original position again by means of the locking element 23 , a counter stop 55 is provided on the adjusting part 15 , which is located in the elongated receptacle 21 On the side opposite to the front of the stop 27, the locking element 23 presses against this counter-stop when the locking element 23 is pressed in this direction (generally when the window or door is closed). Through the oblique guidance of the pin 39 in the elongated hole 37 , the action of this force causes a corresponding oblique movement of the adjustment element 15 back into its original position until the state shown in FIG. 2D is achieved again. From there, the locking element 23 can again be moved to its other longitudinal position in order to adjust other open or closed positions of the window or door.

In the embodiment shown in FIGS. 1 and 2, holes 57, 59 (see FIG. 2E) are preset on the base member 13 and the adjustment member 15 respectively, and in the original position of the adjustment member 15, these holes are aligned with each other. . Therefore, these holes 57, 59 can be used to fix the adjusting member 15 in its original position by inserting pins or bolts (not shown), so that the locking member 11 can be used as a conventional locking member without It has the function of allowing restricted lateral movement of the protected locking element 23 .

However, the holes 57, 59 can also be designed to accommodate magnetic elements that attract each other as positioning elements, at least as long as no force exceeding this magnetic force acts laterally on the adjustment element 15, these magnetic elements will The adjustment member 15 remains in the original position. In this way, it is possible to prevent the adjusting part 15 from being moved out of the original position unintentionally (ie, for example, when the locking element 23 is not in the safe tipping position ( FIGS. 2D and 2E ) and is not pressed against the adjusting part 15 . In addition, since the adjusting member 15 is engaged in the original position based on the mutual magnetic attraction force of the magnetic elements, such a magnetic element can also ensure that the original position is reliably and completely reached. Alternatively or additionally, the magnetic elements can be provided in such a way that they are mounted such that the offset position of the adjustment element 15 can be secured in a meshing manner.

In the embodiments in FIGS. 3A to 3C , a particularly compact locking element 11 is shown as an example, which despite its small size has a locking mechanism protected in an elongated receptacle 21 of the locking element 11. The described function of the limited lateral mobility of the element 23 . Wherein, elements in FIGS. 3A to 3C correspond to elements in FIGS. 1 and 2 and are marked with the same reference numerals.

According to the exemplary embodiment shown in FIG. 3 , the closure element 11 corresponds substantially to the right part of the exemplary embodiment shown in FIGS. 1 and 2 . In this case, the elongated receptacle 21 is again defined by the region that the locking element 23 can occupy in its different longitudinal positions in the direction of the longitudinal axis L, and the elongated receptacle can thus also be locked. 11 extends outside. In particular, the closure element 11 shown in FIGS. 3A to 3C has no (immobile) further stop 29 . In order to still lock the locking element 23 in the locked position so as to prevent it from moving laterally out of the elongated receptacle 21 , a separate further locking element 61 can be provided (see part shown with spaced lines in FIG. 3A ) , the other locking element 61 has a (fixed) further stop 29 and can be designed in a conventional manner.

Furthermore, the closure 11 shown in FIGS. 3A to 3C is functionally completely equivalent to the closure shown in FIGS. 1 and 2 . The longitudinal position of the locking element 23 shown in FIG. 3A is, for example, the tipped open position, in which the locking element 23 is released by the channel part 25 for lateral removal of the elongated receptacle 21 . 3B and 3C show the secure tipping position of the locking element 23, wherein the adjustment element 15 in FIG. 3B is located in the original position as in FIG. can be pressed (in particular by the locking element 23 ) into the deflected position as shown in FIG. 3C . During this movement obliquely to the longitudinal axis L, the locking element 23 also undergoes a limited movement transversely to the longitudinal axis L relative to the base part 13 .

Since this embodiment has only a single pin 39 and a single elongated hole 37, the pin 39, which should have a circular cross section, is ground flat in the region of the elongated hole 37 towards its two longitudinal sides. (See the dotted lines in FIGS. 3A to 3C ), thereby avoiding possible rotation of the adjusting member 15 around the pin 39 . Since the illustrated exemplary embodiment is understood to be purely exemplary, the rotational locking of the adjustment part 15 relative to the base part 13 can also also be effected by other (guiding) elements and/or in other ways.
