The present invention relates to a channel latch for mounting in a door or window sash, comprising a cuff for attaching the channel latch to a fold of the door or window sash and operable by pivoting out of a plane of the cuff lever, which at least one by the pivoting the lever is a translational movement exporting, is coupled from a locking position into an unlocked position and back convertible locking element.

A canister with the aforementioned features is made DE 20 2006 008 969 U1 known. Can-hangers are used in particular for fixing fixed leaf double-leaf door or window systems. To actuate the locking elements, a lever pivotally mounted in the lock housing of the can latch has to be pivoted out of the plane of the cuff. At the DE 20 2006 008 969 U1 previously known Kantriegel the lever is coupled via a coupling device with the locking elements. The manufacture of the channel bolt is complicated by the provided between the lever and the coupling means second actuating mechanism. In addition, the forend forms a wall of the lock body and must be elaborately welded to the other walls of the lock body.

Object of the present invention is therefore to solve the problems described with reference to the prior art, at least partially, and in particular to provide a can bar, the production of which is simple and easy to do.

This object is achieved by a canister with the features of the independent claim. Advantageous developments of the can crucible are specified in the dependent claims and in the description, wherein features of advantageous developments in a technologically meaningful manner are combined with each other.

The problem is solved in particular by a channel latch with the features mentioned, wherein the lever is rotatably connected to a pinion arranged on its pivot axis, wherein teeth of the pinion engage in recesses on the translationally movable locking element, so that the rotation of the pivotal movement of the lever driven pinion drives the at least one locking element translationally.

The invention thus provides that the conversion of the pivotal movement of the lever in the translational movement of the at least one locking element via a pinion whose axis of rotation coincides with the pivot axis of the lever and which engages directly in recesses on the locking element. Between the lever and locking element in particular only the pinion is provided, which can be easily arranged in the lock body during manufacture.

In particular, the lever is pivotally mounted so that its pivot axis is aligned parallel to the plane of the forend, so that the lever is swung out of the plane of the forend when actuated. In the locked position In particular, a locking rod connected to the locking element is moved over a lower or upper end face of the window or door leaf and can engage in a correspondingly provided recess. In the unlocked position, the locking rod is pulled into the door leaf. To the locking element so provided for the particular purpose lock rods can be attached.

The teeth of the pinion are adapted in their cross-section in particular to the recesses in the locking element and vice versa, so that the offset by the lever in rotation pinion translates the locking element by continuous engagement of adjacent teeth in adjacent recesses of the locking element.

In one embodiment of the channel bolt is provided that the forend is attached to a front wall of a lock body, wherein in the lock body, the lever is rotatably mounted together with the pinion and the at least one locking element is mounted translationally movable. It is preferred that the lock body consists of at least one injection molded part, to which the forend can be attached. The forend can, for example, be attached to the front wall of the lock body by means of countersunk blind rivets. The forend is therefore not directly part of the lock body. In particular, projections or recesses are formed on the lock body itself or on a cover closing the lock body, in or between which the lock element can be moved translationally and in or on which the pinion is rotatably mounted.

In a further embodiment of the channel latch is provided that a spring element at all times acts on an actuating region of the lever with respect to the pivot axis eccentric region, so that the lever is biased either in the unlocked position or in the locking position and thus prevents unintentional actuation of the locking element. As long as the eccentric region of the lever has not exceeded a maximum deflection in the direction of the spring element, the spring element ensures that the lever always returns to its starting position. If, on the other hand, when the levers are moved against the spring force beyond the maximum deflection of the eccentric region in the direction of the spring element, then the spring element urges the lever such that the lever reaches the target position.

In order to enable a particularly simple manufacture of the channel bolt, it is provided that the lock body is designed so that for assembly the pinion can be inserted in a predetermined position in the lock body and the lever is laterally mounted on the pinion, wherein the lever through a gap is pivotable between the front wall of the lock body and a side wall mounted as a lid on the lock body, wherein the gap corresponds to an opening arranged asymmetrically in the forend. In particular, the pinion can initially be inserted into a circular exception or into a mounting position formed by projections. Subsequently, the lever is inserted into the pinion, wherein the lever in the adjacent to the side wall gap of the front wall of the front wall can be swung out. The forend has, in a region corresponding to the gap, an opening, which is thus formed in particular asymmetrically with respect to a central longitudinal axis of the forend. Only after the lever has been inserted into the pinion, the forend can be attached to the front wall of the lock body. It can thus be achieved that the pinion and the lever are first placed without tools in the lock body, wherein the positional fixing is achieved by the lid, which is then screwed, for example, to the lock body and thus forms a side wall of the lock body. In particular projections and recesses may be formed on the cover, which fix the lever and / or the pinion in their position in the lock body. For example, an axle may be formed on the cover about which the lever is pivoted and about which the pinion rotates.

If the forend is integrally formed with the lock body or the lid, the opening corresponding to the gap is formed correspondingly in this component.

In order to further simplify the mounting of the channel bolt, it can be provided that the lock body is designed so that the spring element designed as a leaf spring in the lock body in a predetermined position can be inserted, wherein the leaf spring is fixed by the particular releasably attachable to the lock body lid , The leaf spring is aligned after assembly so that it biases the lever either in the locking position or the unlocked position.

In particular, it can be provided that a cover which can be detachably attached to the lock body holds the elements inserted or inserted in the lock body in their respective position, wherein the cover forms a side wall of the lock body.

The channel latch 1 shown in the figures is intended for mounting in a door or window sash, wherein the channel latch 1 is fixed with a forend 2 on the door or window sash. The channel latch 1 comprises a lever 3, which is pivotally mounted in a lock body 9. In the region of its pivot axis of the lever 3 is rotatably connected to a teeth 6 having pinion 5. The teeth 6 of the pinion 5 engage in recesses 7 in locking elements 4, wherein the locking elements 4 are mounted translationally movable in the lock body 9. In the lock body 9, a leaf spring 10 is further arranged, which acts on an actuating region 11 of the lever 3 opposite eccentric 12. The lever 3 can be pivoted laterally past a front wall 8 of the lock body 9. The forend 2 has for this purpose a corresponding opening 13 through which the lever 3 passes during pivoting. The opening 13 is asymmetrically formed in the forend 2 with respect to its longitudinal axis.

Like from the Fig. 1 and 4 can be seen, are the locking elements 4, which can be connected to locking rods, in a locking position on the closure body 9 addition. In the locking position, the leaf spring 10 acts on the eccentric portion 12 of the lever 3, that the lever 3 can not be operated inadvertently.

If now the lever 3 is manually pivoted out of the plane of the forend 2 by actuation of the actuation region 11, then the pinion fastened in a rotationally fixed manner to the pivot axis of the lever 3 rotates, wherein the teeth 6 of the pinion 5 engage in the recesses 7 in the locking elements 4, so that they are moved translationally and are drawn into the lock body 9 ( Fig. 2 and 5 ). By the pivotal movement of the lever 3 of the eccentric 12 of the lever 3 counteracts the spring force of the leaf spring 10. After the lever 3 has been pivoted by more than 90 degrees, the spring 10 acts on the eccentric 12, that the lever in his in the Fig. 3 and 6 shown unlocked position is biased. In the unlocked position, the locking elements 4 are retracted into the lock body 9.

Like from the Fig. 7 can be seen, 9 pin-like and plate-like projections are formed on an inner side of the lock body, at or between which the locking elements 4 and the pinion 5 can be inserted. Thus, first, the pinion 5 and the locking elements 4 are inserted into the lock body 9. Subsequently, the lever 8 is attached to the pinion 5, so that the operating portion 11 of the lever 3 is disposed in a corresponding gap formed between the front wall 8 and the lid 14. Subsequently, the leaf spring 10 is attached to provided projections, wherein the leaf spring 10 acts on the eccentric portion 12 of the lever 3.

Subsequently, the faceplate 2 can be fastened to the front wall 8 of the lock body 9, wherein the actuation region 11 of the lever 3 is arranged in an opening 13 of the forend 2 and the lever 3 can thus no longer be removed from the lock body 9. In addition, the opening 13 in the forend 2 is formed so that it corresponds to the gap between the front wall 8 and lid 14, through which the lever 3 is pivoted. Finally, the cover 14 is fastened, for example by means of screws to the lock body 9, whereby the elements arranged in the lock body 9 are additionally held in their respective position.
