Lock, especially lever lock

The invention relates to a lock, in particular a lever lock with a movable rotating part that guides the lock into its release or locking position and with a housing that serves to attach it to an object such as a door. The rotating part is rotatably mounted in the housing.

Such locks are used in many different ways. They have a simple structure and are used to lock doors, especially locker doors, windows, etc. One disadvantage is that such locks are difficult to operate due to their small size, and another is that they have a relatively simple appearance. Another disadvantage is that such locks are often not customizable. In particular, with locker locks it is often necessary that access is limited to one or a few people. Due to the small size of locks of this type, customization is often only possible via

Small and simple, i.e. insecure, or very expensive cylinder locks with corresponding keys are possible. In addition to the cost or insecurity of the lock, this has the disadvantage that the number of people authorized to access the lock cannot be expanded at will and, if necessary, restricted.

The object of the invention is therefore to design a lock of the type mentioned at the beginning in such a way that it is easy to operate and easy to change in appearance and at the same time enables the installation of freely customizable locking parts, such as number combination locks, particularly with regard to the space required for installation.

This is achieved according to the invention in that the rotating part has a trough-like recess from which a handle protrudes for operating it, which serves to accommodate a number combination lock as a locking part, which optionally blocks or releases the rotation of the rotating part.

A particularly advantageous embodiment offers a conditional individualization of the lock. In addition to the

A further so-called master lock is attached to the combination lock, which can be used to bypass or modify the function of the aforementioned combination lock. Such a master lock is preferably also located in the handle of the rotating part. However, an arrangement outside the handle is also possible.

Preferably, the function of the combination lock is activated by operating the master lock, which can be used as a cylinder or

Buse · Mentzel· · «Ludewig !.**. · *···· ·

Chip card lock can be modified in one or more of the following ways.

1. The master lock can be used to easily bypass the combination lock
serve, ie the transfer of the lock from its release to the closed position or vice versa, i.e. the release or blocking of the rotating part, can also be triggered without operating the number combination lock by operating the other lock alone.

2. By operating the master lock, the number combination
reset, which should then release the rotation of the rotating part. In this simple way, authorized bodies can control the circle of people authorized to access the system or, if necessary, restrict it.

3. Decoding the aforementioned combination lock. By pressing
of the master lock, a mechanism is set in motion that allows the individual number rings to be adjusted using the combination lock until the respective number is set that enables the rotation. In this way, authorized persons can check the coding of the combination lock if necessary.

Preferably, the function of the combination lock can be modified by operating the master lock in all of the ways mentioned above. The desired type of modification could be selected, for example, by setting a master key.

For the joint solution, including the first-mentioned object of the invention, it is therefore particularly advantageous to attach the rotating part to the housing by clipping it on. This enables a quick and simple connection between the rotating part and the housing. In addition, other rotating parts can easily be used depending on their appearance, which in turn can be attached by clipping them on.

Advantageously, the clip-on connection is designed as a snap-in connection, where the catches of the rotating part slide into the counter catches of the housing when the handle is rotated, so that it is ensured that a secure hold between the two parts is guaranteed during opening and closing.

To simplify assembly and save material, it is particularly advantageous if the handle is made in one piece with the turned part. Although this requires the use of a rather complicated tool, it helps to reduce costs in the long term due to the material savings and easier assembly mentioned above, as well as the reduced susceptibility to damage or deliberate destruction.

In a special embodiment of the invention, the rotating part is made of plastic and the housing is made of injection-molded zinc. This can significantly reduce manufacturing costs. It is advisable for the rotating part to have a hole for a locking part so that the lock can also be locked.

Advantageously, the handle provided on the rotating part has a widening at its free end in order to facilitate the operation of the lock, since a user's hand can be prevented from slipping.

It is recommended that the locking part arranged in the handle slides in its release position in a guide track on the housing to ensure that the rotating part is movable in order to block the movement of the rotating part.

In a further, special embodiment of the invention, the rigid housing part is provided with a recessed grip for moving the door equipped with the lock. The recessed grip, which is fixed to the door, allows the door to be opened and closed easily if the lock is in its open position, since the user can easily reach the door via the lock.

In a further embodiment, the housing is divided into individual sections, which allows the housing to be quickly converted or modified, and in this way the user can achieve or reach the optimal shape.

In a particular embodiment of the invention, the rotating bowl is of such a size that it takes up at least one third, but no more than two thirds of the surface of the housing. In this way, safe operation is achieved, since the corresponding handle can be made relatively large.

In the drawings, the subject matter of the invention is shown in several embodiments, namely:

to clarify the clip-on feature.

The lock 10 shown in Fig. 1 has a housing 11 and a rotating part 12 as well as a combination lock 30. The rotating part 29 is designed as a recess or bowl 29 from which the handle 28 rises. The embodiment shown in Fig. 1 has further advantageous details. The separating joints 36 which separate the individual parts of the divisible housing 11 from one another are clearly visible. The design of the housing as a part consisting of several sub-units enables the housing to be easily converted or customer-specific changes to be made.

Also visible in Fig. 1 is the recessed handle 31, which is used for convenient opening, e.g., a locker door.

The release lever 32, which in this particularly advantageous embodiment shown in Fig. 1 is mounted above the number combination lock 30 in the handle 28, serves for an additional unlocking, which is necessary after setting the appropriate number combinations on the number combination lock 30 in order to move the rotating part 12.

Fig. 2 shows a similar lock, which, however, has as a further feature an additional, so-called master lock 30' in the area of the handle 28. As already described, such a design is suitable for enabling a conditional and, in particular, controllable individualization of the lock.

Fig. 3 shows a further embodiment of the lock according to the invention, which here shows a master lock designed as a chip card lock, which has to be attached outside the handle 28 due to its dimensions. In this embodiment, the function of the number combination lock 30 is modified by inserting the chip card 34 into the slot 33 depending on the programming.

Fig. 4 shows the side view of a lock according to the invention installed in, for example, a door 21. The housing 11 is secured in an opening through the door 21 by means of a nut 19 screwed onto the thread 20. The bolt 17 is clearly visible, which is transferred from a closed position to a released position or vice versa when the door 21 is locked or opened. The rotating part located above the door in Fig. 4 is designed to be clipped on in this embodiment, with the holder being provided by a locking mechanism with catches 14 on the rotating part and counter catches 15 on the housing 11. The catches 14 are engaged behind the housing in such a way that they can slide along the counter catches 15 when the rotating part 12 rotates.

As mentioned, the handle 28 is connected in one piece to the rotating part 12. Of course, another multi-part design is also conceivable, which

For example, it allows the handle to be easily replaced in order to accommodate customer-specific design ideas.

The embodiments shown and described here are intended to merely illustrate possible designs of the lock according to the invention and are not intended to limit them in any way. In particular, many variations are conceivable with regard to the special technology and the locking mechanisms.
