Description

The present invention relates to a lock with a lock housing, a face plate, a latch, at least one latch, an operable via a door handle follower and a lock cylinder receptacle.
For door locks, there are standardized dimensions such as the so-called backset, which refers to the distance from the center of the door handle and the keyhole to the outer edge of the lock and which is one of the most important dimensions of locks.
For different mandrel sizes each own lock housing and different mechanical components are needed so far, which is relatively expensive and correspondingly expensive. In addition, in the previously known locks of the type mentioned in the production relatively inflexible and associated with a high storage requirements. In addition, in the usual motor locks the motor is either integrated with the above-mentioned disadvantages in the housing or it is mounted a separate motor module above or below the castle, which requires additional recesses in the door and makes retrofitting almost impossible.
The WO 03/027422 A1 discloses, for example, a lock with a closing module and a drive module, wherein the closing module and the drive module are variably interchangeable. The two modules are screwed together and provided with an additional housing cover. The invention has for its object to provide a lock of the type mentioned, with which the aforementioned disadvantages are eliminated. In this case, the lock with rational production as possible and the lowest possible storage requirements by a variable function, execution and / or retrofitting in particular also be flexibly adaptable to different requirements.
The object is achieved by a lock with the features of claim 1. Preferred embodiments of the lock according to the invention will become apparent from the dependent claims, the present description and the drawings.
The lock according to the invention comprises a lock housing, a cuff, a latch, at least one latch, a handle nut which can be actuated via a door handle and a lock cylinder receptacle. The lock is modular and divided into a forehead, the bolt and the at least one trap comprehensive locking module and the follower and the lock cylinder recording comprehensive drive module.
Due to this design, the lock with rational prefabrication and lower storage requirements is more flexible adaptable to different requirements. For a particular adaptation or retrofitting of the castle essential components of the castle can remain unchanged. For example, different combinations of closing and drive modules (eg electromechanical, mechanical, etc.) but also different mandrel dimensions can be realized by replacing simple sheet metal parts, for example on the drive module, without the other module must be changed.
The closing module and the drive module suitably comprise mateable lock housing parts. If, for example, the backset is to be adjusted or varied, then, for example, the lock housing part of the presser nut and the lock cylinder comprising the drive module can be adapted accordingly. The lock housing part of the closing module remains unchanged in this case.

The closing module and the drive module can be effectively coupled to each other by a plug connection.

As already mentioned, for example, the backset of the lock can be varied by a different combination of closing module and drive module.

In addition, by a different equipping at least one of the lock modules, for example, a purely mechanical lock, an electromechanical lock or a motor lock can be realized. By an appropriate combination of locking module and drive module can thus be realized in particular a purely mechanical lock, an electromechanical lock or a motor lock. For the realization of a motor lock, the drive module preferably comprises a motor unit.

According to a further expedient embodiment of the lock according to the invention, the drive module may comprise a split, electromechanically coupleable follower. With such a fitting or retrofitting of the drive module, it is possible to decouple the pusher of a lock side of the opening mechanism, whereby the access can be controlled in a secure area. This can be done by an access control such as an electronic access control system. In case of authorized access, the two halves of the follower can be electromagnetically triggered and coupled together, so that the lock can also be actuated via the outer handle.

According to a preferred practical embodiment of the lock according to the invention, the closing module comprises a cross latch with two latching elements arranged on opposite sides of the latch.

It is particularly advantageous if the lock also includes an auxiliary trap. In this case, the latch elements of the cross latch with the auxiliary latch are preferably operatively connected such that the latch only then in its locking position is movable when after simultaneous operation of the trapping elements of the cross latch and the auxiliary latch, the latch elements of the cross latch were moved to its locking position, wherein the auxiliary latch remains actuated.

The split arrangement of a cross latch with two mutually opposite sides of the bolt arranged latch elements allows centering of the lock against a strike plate and thus a safe exclusion and intervention of the bolt in the recess of the strike plate in question. In this case, the latch elements can pivot out of the lock into the relevant recess in the strike plate, so that they respectively bear against one of the mutually opposite inner sides of the recess. The bolt can thus freely engage in the strike plate. A possibly existing inclination of the striker against the lock, for example, due to a delay of the door can be compensated due to the distance between the latch elements.

In certain cases, it is also advantageous if a panic lock for an escape and rescue route can be realized by an appropriate combination of closing module and drive module. It can be ensured in particular by the relevant panic function that with the depression of a handle such as a door handle or the like, the bolt and the traps are pulled back into the lock, whereby the previously closed door is released immediately.

The Fig. 1 and 2 show a schematic representation of an exemplary embodiment of a lock 10 according to the invention for a door or a window.

The lock 10 comprises a lock housing 12, a forend 14, a latch 16, at least one latch 18, a presser foot 20 which can be actuated via a door handle and a lock cylinder receptacle 22.

The lock 10 has a modular design and is divided into a lock module 14, the latch 16 and the at least one latch 18 comprehensive closing module 24 and the follower 20 and the lock cylinder receiving 22 comprehensive drive module 26.

As based on the Fig. 1 and 2 1, the closing module 24 and the drive module 26 can comprise lock housing parts 12 ', 12 "that can be joined together in an appropriate manner. The closing module 24 and the drive module 26 can be effectively coupled to one another, for example, by a plug connection.

The separation into a closing module 24 and a drive module 26 allows for rational prefabrication and storage of the castle 10. In addition, different backset variants and different locks such as a. By a combination of different locking and drive modules 24, 26 and by a different equipping of the modules purely mechanical lock, an electromechanical lock or a motor lock can be realized.

Thus, by a different combination of closing module 24 and drive module 26, for example, the backset of the lock 10 can be varied, for example by replacing simple sheet metal parts of the two modules 24, 26. The other module or housing part thus remains unchanged.

As already mentioned, by a corresponding combination of closing module 24 and drive module 26, for example, a purely mechanical lock or an electromechanical lock can be realized.

The drive module 26 may comprise, for example, a split, electromechanically coupleable follower 20. In particular, this makes it possible to decouple the pusher of a lock side from the opening mechanism, whereby access to a secured area can be controlled. This can be done by an access control such as an electronic access control system. With legitimate access, the two halves of the follower 20 are electromagnetically coupled together, so that the lock 10 can also be operated via the outer handle.

For realizing a motor lock, the drive module 26 may, for example, also comprise a motor unit or be equipped with such a motor unit.

The closing module 24 may, for example, comprise a cross latch with two latching elements 18 ₁ , 18 ₂ arranged on opposite sides of the latch 16.

As based on the Fig. 1 and 2 can be seen, the closing module 24 may also include an auxiliary latch 28. The latch elements 18 ₁ , 18 _{2 of} the cross latch with the auxiliary latch 28, for example, be operatively connected such that the latch 16 is only movable into its locking position when after simultaneous operation of the latch elements 18 ₁ , 18 _{2 of} the cross latch and the auxiliary latch 28 the Trap elements 18 ₁ , 18 _{2 of} the cross latch were moved to its locking position, the auxiliary latch 28 remains actuated.

By a corresponding combination of closing module 24 and drive module 26, for example, a panic lock for an escape and rescue route be feasible. It can be ensured in particular by a corresponding panic function that all locking elements and traps are pulled back into the lock 10 by pressing a handle such as a door handle, so that the previously locked door is released immediately.
