A fitting assembly for doors, windows and the like having a locking bar with an adjustable length. The locking bar comprises a first sub-bar and a second sub-bar movable relative to each other along a longitudinal axis of the locking bar. The sub-rods are movable relative to each other along the longitudinal axis of the locking rod, wherein a toothing is provided on the first sub-rod and a counter-toothing is provided on the second sub-rod. The toothing and the counter toothing are designed to mesh with each other in order to fix the two sub-bars relative to each other according to the desired length of the locking bar. The counter-toothed portion is rotatably mounted on the second sub-rod about a rotational axis between a locking position in which the counter-toothed portion engages the toothed portion and a releasing position in which the counter-toothed portion releases the toothed portion to effect movement of the sub-rods relative to each other.

Description

Accessory assembly

Technical Field

The invention relates to a fitting assembly for doors, windows or the like, having a locking rod with an adjustable length, which comprises a first and a second sub-rod that are movable relative to each other along the longitudinal axis of the locking rod.

Background

Such a fitting assembly can be mounted, for example, on a leaf of a door or window, in particular in a fitting slot on the leaf, so as to interact with a corresponding element on the frame of the door or window to achieve different opening and locking states of the leaf. For example, a handle or other operating element is provided, the operation of which is guided by the drive to the adjustment of the locking lever. The locking bar is therefore usually moved along the respective narrow side of the sector, parallel to the longitudinal axis of the locking bar. A pin, for example, may be provided on the locking lever. The pins engage with respective closing portions fixed to the frame, depending on the position of the locking lever, so as to lock the sector to the frame. One end of the locking lever projects from the sector depending on the position of the locking lever from the corner of the sector and engages in the longitudinal direction with a receiving portion provided on the frame, so that the locking lever itself can also interact with the frame, for example as a so-called lever stop.

The locking bar may also be guided around the corners of the sectors by corner deflectors. When the locking lever is designed as a multi-part lever composed of at least two sub-levers, the individual sub-levers must be reliably couplable or coupled to one another in order for the individual locking elements provided on the locking lever (for example, the pin or the end of the locking lever which is the lever end stop) to be effectively drivingly connected with the driver in a defined manner. Only then can the locking rod reliably transmit the operating stroke from the driver to the respective locking element. Since the locking bar is used for the transmission of the drive movement, the locking bar or at least a part of the locking bar is a drive bar as an accessory component.

In order to enable the fitting assembly to be fitted to windows and doors having different sizes, it is common to produce the locking bar with a margin so that the locking bar can be cut to a desired length. This is not easy to achieve, however, when the locking lever has a special design at its end, for example for coupling the drive on the one hand and as a lever stop on the other hand. Since the locking bar needs to be shortened in the middle area in order not to affect this special structure. In particular in these cases, the following is advantageous: the locking lever is designed as a plurality of parts with at least one first and one second sub-lever, and the first and second sub-levers can be coupled or coupled to each other. As such, for length adjustment of the locking bar, one of the sub-bars may be cut to the end coupled with the other sub-bar.

When the locking lever is designed to be substantially length adjustable so that cutting is not required, more convenient length adjustment is achieved. To this end, the first and second sub-bars may be movable relative to each other along the longitudinal axis of the locking bar and fixable relative to each other according to the desired length of the locking bar. For example, the two sub-rods can first be moved such that the locking rod has the desired length and then telescoped or clamped into each other transversely to the longitudinal axis in order to fix the sub-rods relative to each other. For this fixing of the relative longitudinal arrangement of the two sub-rods, a mutual displacement of the sub-rods is required, which displacement again slides over the set length.

It is therefore more practical that when the sub-rod is only fixed relative to the longitudinal arrangement after movement, the sub-rod itself does not need to be moved for fixation. For example, one toothing can be provided on each of the two sub-rods and a gear wheel can be provided between the sub-rods, wherein the toothing of the two sub-rods meshes with the gear wheel and the toothing and the gear wheel rotate together when the sub-rods are moved relative to one another. By the fixation of the gear wheels, it is then possible to fix the relative longitudinal arrangement of the sub-rods and thus the length of the locking rod. This construction is relatively complicated and costly due to the additional gears required and the tools for gear placement and fixing.

Disclosure of Invention

The invention aims to provide a fitting component for doors and windows and the like. The locking lever of the fitting assembly is designed in a particularly simple manner to be adjustable in length and can be reliably fixed over a set length.

This object is achieved by a fitting assembly having the features of claim 1. Advantageous embodiments of the invention emerge from the dependent claims, the following description and the figures.

According to the invention, the fitting assembly comprises a length-adjustable locking lever having a first sub-lever and a second sub-lever. The first and second sub-bars are movable relative to each other along a longitudinal axis of the locking bar. By means of this displacement of the two partial rods, in particular their mutual circumferential overlap is changed. To adjust the length of the locking bar, the sub-bars are moved successively, parallel to the longitudinal axis, toward and away from each other until the desired length is assumed. To secure the locking bar over this length, the sub-bars may be secured in their relative longitudinal arrangement which is then presented. For this purpose, a toothing is provided on the first sub-bar of the locking lever, while a counter-toothing is provided on the second sub-bar of the locking lever.

The toothing and the counter toothing are designed to mesh with one another, so that the two sub-bars are fixed relative to one another according to the desired length of the locking bar. In other words, by mutually engaging the teeth on the first sub-rod and the counter-teeth on the second sub-rod, the two sub-rods are at least temporarily prevented from moving further relative to each other along the longitudinal axis. A renewed movement of the sub-rods (for example, in order to correct a wrongly set locking rod length) may thus, but not completely, be excluded. However, for this purpose, the toothing between the toothing and the counter toothing must first be pushed apart again.

One main aspect of the invention is that the counter-toothing on the second sub-rod is movably arranged. In particular, the counter toothing is rotatable about a rotational axis between a locking position and a release position. In the locked position, the counter-teeth engage with the teeth. In the release position, the teeth are released from the teeth to effect movement of the sub-rods relative to each other. This rotatable arrangement of the teeth on the second bar provides: it will be said for the teeth that they are rotated inwards to engage with the teeth so that the two sub-rods are reliably fixed relative to each other. Since the fixing of the sub-rods in the defined longitudinal arrangement is thus achieved by the rotation of the teeth, no further movement of the sub-rods relative to one another is necessary for the fixing after the sub-rods have been moved to the desired length. This contributes to a simplified length adjustment operation. In particular, the counter toothing or such an element on which the counter toothing is arranged can be turned by hand. Alternatively or additionally, a tool engagement element (for example in the form of an internal hexagonal socket or an internal hexagonal splined socket (Torx)) can also be provided on the counter toothing in order to be able to rotate the counter toothing by means of a tool engaged in the tool engagement element, which can be particularly useful if the rotation of the counter toothing is relatively laborious.

According to an advantageous embodiment, the teeth will be arranged rotatably about a rotational axis, which is at least substantially perpendicular to the longitudinal axis of the locking lever. Thereby, the counter-teeth can be brought into contact with the teeth on the first sub-lever about the axis of rotation in a rotational direction substantially perpendicular to the longitudinal axis of the locking lever. This perpendicular engagement prevents the first sub-lever from moving more in the longitudinal direction than is necessary for an exactly adapted engagement when adjusted to the locking position.

The teeth and counter-teeth can be staggered transversely to the longitudinal axis in this way, as a result of which the sub-rod is locked in a form-fitting manner (formschl ü ssig) in relation to the longitudinal direction.

According to a further advantageous embodiment, the sub-bars have an at least approximately rectangular cross section, the longer sides of which form the flat sides of the first sub-bar, and the shorter sides of which form the narrow sides of the first sub-bar. In particular, the cross section is related to the longitudinal axis of the locking bar so as to orient the flat side and the narrow side of the first sub-bar perpendicular to the longitudinal axis. Wherein the toothing is designed on at least one narrow side of the first bar. The narrow side of the first bar is relatively well treated due to its small thickness, so that the teeth are easily arranged there. For a reliable engagement of the toothing with the toothing on the narrow side, the axis of rotation of the toothing is preferably oriented perpendicular to the flat side of the first bar.

Preferably, teeth are provided on both narrow sides. In this manner, the pair of teeth provided on the second sub-rod may be engaged with the teeth optionally on one side or the other of the first sub-rod. Furthermore, the counter toothing can also be designed to engage with the toothing simultaneously on two mutually opposite narrow sides of the first bar when turned into the locking position. By means of this double-sided engagement with the toothing of the first partial rod, a particularly stable fixing of the two partial rods relative to one another is achieved. Since the first sub-rod cannot be retracted (e.g. due to play) and thus a disengagement from the engagement of the teeth takes place.

It is also preferred that the first sub-rod has a base aligned with the second sub-rod and an end section offset parallel thereto. The tip section is connected to the base by a step and provided with teeth thereon. By the base of the first sub-rod being aligned with the second sub-rod is meant that the base extends at least substantially in the same direction (preferably with at least substantially the same cross-section) as the elongation of the second sub-rod. Wherein the distance between the base of the first sub-rod and the second sub-rod may be variable due to the length adjustability of the locking rod. In this case, the base is preferably designed as a main part of the first sub-rod. In particular, the extension and longitudinal axis of the locking bar is defined by this aligned arrangement of the base of the first sub-bar and the second sub-bar.

Said end section of the first sub-rod is offset parallel with respect to the base, but is connected to said base. For this purpose, a step is provided between the base and the end section, which step can be designed as a right-angled step or as a ramp in the manner of a ramp, or else can form a transition between the base and the end section. Preferably, the cross section of the first sub-rod in this case remains at least approximately constant, so that the base and the end section (irrespective of the toothing) have the same cross section. In order to form such a layer, the first partial rod can, for example, be bent or bent twice in succession in mutually opposite directions, wherein the deflection angles in both cases are of the same size such that the base and the end section run parallel to one another.

This parallel offset end section achieves an overlap of the first sub-rod with the second sub-rod, while the other aspects of the two sub-rods are aligned with one another and in this way form a substantially overall linearly extending locking rod. Means may be provided in said overlapping area so that the two sub-bars are fixed relative to each other. In particular, for this purpose, a toothing is provided on the end section of the first partial rod. Furthermore, the partial rods can have means in the region of the overlap, by means of which the partial rods can be coupled or at least guided movably relative to one another, as long as the toothing is not yet locked in movable engagement with the toothing.

It is also advantageous if the fitting assembly is designed such that the counter toothing is blocked in the locking position. In other words, in an embodiment in which the locking position is reached at the latest, the toothing is automatically protected against disengagement from the locking position by the detent mechanism. This protection may, but need not, be in an irreversible manner. In principle, this can be: the protection in the locking position represents only a mechanically critical way, which can be overcome again with sufficient force, so that the toothing can also be released again from the locking position after the locking position has been engaged.

For example, the counter toothing can be provided on an element (for example, a tooth cassette described below) which is rotatably arranged on the second sub-lever, wherein the stop mechanism can be provided between this element and the second sub-lever. The latching means can comprise, for example, a latching recess (e.g. a latching groove) on one side and a resilient latching tongue or a latching element which engages in the latching recess (in particular pretensioned) in the latching position on the other side. In this case, the stop notch can be provided on the element comprising the counter toothing, while the stop element is provided on the second sub-rod. Or vice versa, the stop element is provided on an element comprising the counter toothing, while the stop notch is provided on the second sub-rod. When the element is designed as a tooth box, the stop mechanism can act in particular between the flat side of the second bar and the bottom side of the tooth box oriented to the flat side.

According to a preferred embodiment, the fitting assembly comprises a tooth box rotatably mounted on the second bar, the tooth box having at least one side wall on which the counter-teeth are provided. The counter toothing is therefore not provided directly on the second bar as an integral component, but on a side wall of an element provided substantially separately from the second bar, which element is referred to here as a tooth box, but does not necessarily have to be box-shaped. The rotatability of the toothing can be achieved in a simple manner by the toothed rack being rotatably mounted on the second bar, so that the axis of rotation of the toothing corresponds to the axis of rotation of the toothed rack. At this time, the tooth box has a release position and a lock position, which correspond to the release position or the lock position of the tooth portion. Although in this embodiment the pair of teeth is not provided directly on the second sub-rod, but on the tooth box, preferably the teeth are provided directly on the first sub-rod as an integral component of the first sub-rod, so that the fitting assembly does not need to comprise an additional, separate element for the teeth.

According to an advantageous development, the side wall of the tooth box extends parallel to the longitudinal axis in the locked position between the end remote from the axis of rotation and the end close to the axis of rotation and has a guide bevel at the end close to the axis of rotation. The guide ramp is designed to rest on the toothing parallel to its longitudinal axis in the release position and not to engage with the toothing. By orienting the side walls parallel to the longitudinal axis in the locked position, the counter teeth can be positively engaged with teeth provided on the first bar and preferably also oriented parallel to the longitudinal axis. In this case, the side wall extends along the longitudinal axis between two ends which are at different distances from the axis of rotation of the tooth box or of the counter-tooth. Thereby, the two ends of the side wall move with different radii when rotating around the rotation axis. In particular, when the end close to the rotational axis is arranged at least approximately at the level of the rotational axis in the axial direction, a rotation of the tooth cassette about the rotational axis out of the locking position corresponds approximately to a rotation of the side wall away from the longitudinal axis, so that the first sub-lever is thereby released for displacement.

Due to the small radius of the end of the side wall close to the rotational axis, the tooth box again comes into contact with the first sub-lever (in particular with its toothing) via this end close to the rotational axis, so that the rotational mobility of the tooth box in the release direction is limited. In the above-described embodiment, therefore, a guide bevel is provided on this end, which guide bevel is preferably designed to be oriented parallel to the longitudinal axis when it strikes the first bar or toothing. This position may correspond exactly to the release position.

By providing such a guide ramp, it is not only avoided that the end of the side wall close to the rotational axis engages between the teeth of the toothing in the release position (for example by means of a corner) and thus interferes with the relative movability of the sub-rods, but it can advantageously serve at the same time to provide a defined surface on which the first sub-rod can be guided to slide along during the movement in the release position.

According to an advantageous embodiment, the tooth box has two parallel side walls, the inner sides of which are provided with counter teeth and between which the first sub-rod is guided or fixed movably along the longitudinal axis depending on the rotational position of the tooth box. The tooth boxes can thus be placed on both sides of the first bar by their side walls.

In this way, a reliable guidance of the first bar in the direction of the longitudinal axis on the second bar can be achieved in the release position of the tooth magazine, since the first bar is prevented by the side wall from being detached from the tooth magazine transversely to the longitudinal axis. Preferably, the side wall in the release position rests at least approximately on both sides against the first bar, so that the first bar in the tooth box can be guided axially movably with no or only little play. To this end, the side walls may each have a leading bevel, as described above for the single side wall.

In the locked position, a particularly secure fastening of the relative longitudinal arrangement of the two sub-rods is achieved by the meshing of the counter-toothing on both sides of the first sub-rod on the inside of the side surface of the tooth box with the toothing preferably also on both sides of the first sub-rod.

For a tooth box with two parallel side walls, it is further preferred that the side walls of the tooth box are arranged offset from one another along the longitudinal axis of the locking lever in the locked position. This offset arrangement achieves: the two side walls, on which the counter-toothing is respectively provided, are rotated outwards (or inwards) in mutually opposite directions transverse to the longitudinal axis when turning from the locking position to the release position (or vice versa). For this purpose, the rotary shaft can be arranged in particular in the region of the axial overlap of the side walls offset from one another, or in the region between the side walls in the axial direction when the side walls are offset from one another such that the side walls do not overlap in the axial direction.

In principle, it is further advantageous if the side walls of the tooth boxes (in particular at least taking into account the pairs of teeth arranged thereon) are axially symmetrical to one another with respect to the axis of rotation. In this way, the orientation of the tooth box need not be taken into account when mounting it. Furthermore, the toothed box can interact with the toothing of the first sub-rod equally reliably on both sides by the toothing.

According to a further advantageous embodiment, the tooth boxes can be designed to be circumferentially closed. When the tooth box has two side walls as described above, these two side walls can be connected, for example, by an upper wall pointing away from the second sub-bar and by a lower wall pointing to the sub-bar, so that a circumferentially closed structure is formed. The first sub-rod (in particular the end section of the first sub-rod) can be accommodated in the structure axially movably. The tooth boxes can, however, in principle also be closed circumferentially in other ways, so that there is an axis parallel to the longitudinal axis. The axis is completely surrounded in the circumferential direction by the tooth box, but the tooth box is preferably open on both sides in the axial direction.

The tooth box thus formed has the advantages that: the first partial rod, which is partially accommodated in the tooth box and is surrounded by the tooth box in the circumferential direction, cannot be removed from the tooth box in the radial direction, but rather it can be removed only in the axial direction. Preferably, in this case, the tooth box bears snugly against the first sub-rod, so that the locking lever in the tooth box is only axially movable (irrespective of the remaining clearance). In this way, the first sub-lever is not only laterally prevented from being detached from the tooth box by the side walls of the tooth box, but the first sub-lever can also advantageously not be released from the second sub-lever in the direction of the axis of rotation. The first sub-rod is thereby coupled by the toothed box to the second sub-rod in an axially displaceable manner already before the length of the locking rod is fixed.

In principle, the tooth box need not be closed circumferentially around the first sub-rod. This is also possible, for example: the tooth box has said side walls, the first sub-bar being accommodated between the side walls and being fixable as a result of the rotation of the tooth box relative to the second sub-bar into the locking position. The tooth box can be provided with an opening, in particular in a direction away from the second partial rod (in particular parallel to the flat side of the second partial rod), so that the first partial rod can not only be introduced into the tooth box along the longitudinal axis of the locking lever, but also (similar to the tooth box known to be rigidly connected to the second partial rod) can be inserted into the tooth box transversely to the longitudinal axis of the locking lever in a direction toward the second partial rod.

Furthermore, the toothed box is advantageously pretensioned in the locking position. In order to move the first sub-lever relative to the second sub-lever, the tooth boxes must first be pivoted against the prestress into the release position and held in the release position. Otherwise, the tooth box will be prestressed back into the locking position and thereby fix the length of the locking bar. In this way it can be ensured that it does not lead to an unexpected change in the length of the locking lever, for example when mounting the fitting assembly, which may occur due to gravity. Thus, the prestressing contributes to a simple mounting.

According to an advantageous embodiment, the tooth magazine in the release position projects from the rest of the fitting assembly transversely to the longitudinal axis by means of at least one corner, whereas it does not project in the locking position. In particular, the fitting assembly is designed to be placed into a fitting groove on a sash portion of a door or window. For a precisely adapted fitting of the fitting assembly, the width of the fitting assembly advantageously corresponds to the width of the fitting groove. When the tooth box protrudes from the rest of the fitting assembly through the corner, it may result in the fitting assembly in this state not being able to be placed into the fitting groove. It is therefore precluded that the fitting assembly is placed into the fitting groove before the length of the locking bar is fixed by rotating the tooth box into the locking position. The possibility of adjusting the tooth magazine into the release position when the fitting assembly is inserted into the fitting groove can also be excluded conversely. The length of the locking bar is reliably fixed in this manner as long as the fitting assembly is prevented from being in the fitting groove.

According to another advantageous embodiment, the tooth box is designed to be pressed into the locking position by the fitting groove by placing the fitting assembly into the fitting groove of the door window. In this embodiment, it is therefore possible to hold the tooth magazine in the release position before the fitting assembly is inserted into the fitting groove. By the insertion process itself, the tooth box is rotated into the locking position by interacting with the fitting groove, so that the fitting assembly can be completely inserted into the fitting groove and locked again by the fitting groove against rotation into the release position. In this way, a convenient and automatic length fixing of the locking bar is achieved when the fitting is inserted.

According to a possible refinement of the above-described embodiment, the tooth box is designed at least approximately in the shape of a cuboid and has a chamfer at the corner of the cuboid shape. For example, the corner refers to the above-described corner protruding from the accessory module according to the position of the tooth box. The beveling may for example be of the type designed as a fillet or a chamfer. Furthermore, the bevelling may interact with the fitting groove, in particular as a sliding ramp, as explained in connection with the following embodiments.

According to a further embodiment, in principle independently of the cuboid design with beveled corners, the tooth box can have a sliding ramp which is designed to come into contact with the window or door outside the fitting groove when the fitting component is inserted into the fitting groove and the tooth box is in the release position and thereby guide the insertion movement into a rotation which rotates the tooth box into the locking position. As mentioned above, the sliding slope refers to a rounded or chamfered corner of the tooth box.

In particular, when the tooth box is in the release position, the sliding ramp projects from the other part of the fitting assembly transversely to the longitudinal axis of the locking lever and is therefore in contact with the door or window (in particular on the rim that delimits the fitting groove to its side) when the fitting assembly is placed into the fitting groove. However, this does not block or hinder the insertion of the fitting component into the fitting groove, but rather the impact causes the toothed box to rotate into a locking position in which the fitting component fits into the fitting groove, so that the length of the locking bar is automatically fixed by the insertion of the fitting component. In this case, the provision of the slide slope on the tooth box has the advantages of: in order to achieve such an automatic length fixing, no additional elements need to be provided.

Detailed Description

An exemplary embodiment of a fitting assembly 11 according to the present invention is shown in perspective in fig. 1. The fitting assembly 11 is not shown in its entirety, but only a section which illustrates the length adjustability according to the invention. The fitting assembly 11 comprises a locking rod 13 for transmitting the operating stroke of the driver, not shown, to a different locking element, also not shown. Furthermore, the fitting assembly 11 has a sleeve track 15, which sleeve track 15 covers the locking lever 13 when the fitting assembly 11 is placed into the fitting groove of the door or window.

By having the locking bar 13 comprising a first sub-bar 17 and a second sub-bar 19, and the first and second sub-bars 17, 19 being movable relative to each other along the longitudinal axis L of the locking bar 13, the length of the locking bar 13 is made adjustable. The two sub-rods 17, 19 are designed as elongated and flat rods. The second sub-rod 19 extends linearly along the longitudinal axis L, while the first sub-rod 17 extends only in a corresponding manner through the base 21 aligned with the second sub-rod 19. In contrast, by bending the first sub-rod 17 twice in respectively opposite directions in the region of the step 25, the end section 23 of the first sub-rod 17 is offset parallel to the base 21 and is connected to the base 21 by the step 25. The parallel offset end section 23 can thus axially overlap the second bar 19 as shown. As can be seen from a comparison of fig. 1 and 2, this axial overlap is variable due to the relative movability of the two sub-rods 17, 19.

However, the fitting assembly 11 has means for axially fixing the first and second sub-rods 17, 19 relative to each other such that they can no longer move relative to each other. For this purpose, a toothing 27 is provided on the first bar part 17, which toothing 27 is formed on two narrow flanks 29 of the end section 23 which is rectangular in cross section. Conversely, the flat side 31 of the end section 23 is designed to be flat. For co-operation with the toothing 27 of the first sub-rod 17, a toothing box 33 is provided on the second sub-rod 19. The tooth box 33 is substantially cuboid and has two opposite parallel side walls 35 transverse to the longitudinal axis L. The two opposing parallel side walls 35 are connected by an upper wall 37 and a lower wall 39. By means of the side wall 35 and the upper and lower walls 37, 39, the tooth box circumferentially surrounds the end section 23 relative to the longitudinal extension of the end section 23 of the first sub-rod 17, so that the end section 23 cannot leave the tooth box in the radial direction. The first sub-rod 17 is thus already coupled to the second sub-rod 19 also when the toothed rack 33 is in the release position (see fig. 4), but can also be moved in the axial direction. In the locked position (see fig. 1 to 3), the first bar part 17 is completely fixed to the second bar part 19.

The tooth box 33 and its interaction with the teeth 27 on the end section 23 of the first sub-rod 17 will be further explained below in connection with fig. 3 and 4. The cassette 33 is rotatably mounted on the second sub-lever 19 about a rotational axis D which is perpendicular to the longitudinal axis L of the locking lever 13 and the flat side 31 of the first sub-lever 17. In this way, the tooth box 33 can be rotated between a locking position shown in fig. 3 and a release position shown in fig. 4.

The tooth box 33 has on the inner side of its side wall 35 a pair of teeth 41 corresponding to the teeth 27, which pair of teeth 41 is parallel to the longitudinal axis L and engages with the teeth 27 in the locked position, the teeth 27 being designed on the narrow side 29 of the first sub-rod 17 and parallel to the longitudinal axis L. In this way, the first and second sub-bars 17, 19 are no longer movable relative to each other in the locked position, but are fixed relative to each other, so that the locking bar 13 is fixed over a predetermined length of the locking bar 13.

The two side walls 35 are designed to be substantially axisymmetric with respect to the axis of rotation D and each extend from an end 43 of the respective side wall 35 remote from the axis of rotation to an end 45 close to the axis of rotation. Wherein the pairs of teeth 41 on the inner side of each side wall 35 each extend from an end 43 remote from the axis of rotation through a substantial part of the respective side wall 35 to (but not completely to) an end 45 close to the axis of rotation. This avoids that one tooth of the counter-toothed portion 41 is partly engaged with the toothed portion 27 or vice versa one tooth of the toothed portion 27 is partly engaged with the counter-toothed portion 41 when the counter-toothed portion 41 is swung into the release position of the position shown in fig. 4.

The ends 45 of the side walls 35 close to the axis of rotation each have a guide bevel 47, which guide bevel 47 is parallel to the longitudinal axis L in the release position and bears flat against the toothing 27 and therefore does not engage the toothing 27. Since such guide ramps 47 are provided on both side walls 35, in the release position the end section 23 of the first sub-lever 17 accommodated in the gear box 33 is guided on both sides by the guide ramps 47, so that the end section 23 can essentially only be moved in the axial direction.

As can be seen from a comparison of fig. 3 and 4, the tooth box 33 in the release position projects from the rest of the fitting assembly 11 (in particular from the sleeve rail 15) via diametrically opposite corners 49, unlike in the locking position. Thus, the release position does not occur as long as the fitting assembly 11 is placed into a correspondingly sized fitting slot.

However, the corners 49 may each have a sliding bevel which is designed such that, when the fitting assembly 11 is placed in the fitting groove and the tooth box 33 is also in the release position, the sliding bevel comes into contact outside the fitting groove with the respective window or the respective door and thereby guides the placing movement into a rotation which rotates the tooth box into the locking position. Thus, when the tooth magazine 33 is in the release position, the fitting assembly 11 can also be inserted into the fitting groove, since it is automatically pushed into the locking position during insertion.
