"Lockable rotating handle"

The present innovation relates to a lockable rotary handle, consisting of a rosette and a hand lever rotatably mounted therein, with a inside the hand lever in a recess of the Rosette insertable, axially displaceable locking bolt actuatable by means of a commercially available half construction cylinder (profile half cylinder) is arranged.

Rotary handles of the generic type are known per se.

In the known rotary handle is an actuating mechanism for the locking bolt is provided, which is triggered via the lock bit of the construction cylinder.

Such a construction allows the inclusion of a lockable rotary handle in a locking system, but it is disadvantageous however, that the dimensions of the hand lever still have to be relatively large in order to control the actuation mechanism for the locking bolt accommodate.

The present innovation is based on the task of creating a lockable To design rotary handle of the generic type so that the hand lever can be made comparatively small, i.e. that

Schneider, Brakel

the dimensions of the hand lever ultimately only through the inclusion of the building cylinder are determined.

This object is achieved according to the invention by the following features:

a) The locking bolt is in alignment with the construction cylinder, b) the locking pin can be inserted into the recess of the rosette against the action of a spring,

c) the construction cylinder is guided axially displaceably in the hand lever,

d) a lock is provided in the hand lever, which when pushed in Locking bolt engages in that recess of the building cylinder in which the lock bit is arranged.

This construction ensures that the hand lever only must have the dimensions that it needs for the recording of the building cylinder needed anyway. The locking pin is actuated by axially displacing the construction cylinder, the locking pin is in Introduced the recess of the rosette, the lock ensures the fixation of the building cylinder within the hand lever, so that the secured rotary position between hand lever and rosette only by actuation the key of the building cylinder can be picked up again. By operating the key and thus also the lock bit that is, only the locking mechanism engaging in the corresponding recess of the building cylinder is disengaged, so that now through the Spring action of the locking pin can be brought out of engagement with the recess of the rosette. The building cylinder also shifts in the process within the hand lever by the appropriate amount.

Further features of the innovation are the subject of subclaims.

In the accompanying drawings are exemplary embodiments of the innovation which are described in more detail below.

In the hand lever 2 there is an axially displaceable locking pin 3, which can be introduced into a recess 5 of the rosette 1 against the action of a spring 4.

The locking bolt 4 is in alignment with half a building cylinder 6, which is also referred to as a profile half-cylinder.

Oer building cylinder 6 is axially displaceable within the hand lever 2 as well as the locking bolt 3.

In Figure 3 it is shown that the locking pin 3 is in a recess 5 of the rosette 1 is inserted.

In this operative position of the locking pin 3, a locking spring 7 engages into that recess 8 of the building cylinder 6 in which the locking bit 9 of the building cylinder 6 is also arranged. The one acting as a lock Spring 7 prevents the building cylinder 6 from being put back, i.e. the position of the locking pin 3 in relation to the rosette 1 is correct secured. Only when the construction cylinder 6 is actuated by means of the associated key can the lock bit 6 the locking spring 7 can be pressed out of the recess 8. This results in free axial movement of the building cylinder 6 and thus also the locking pin 5 allows. Due to the spring 4 is the Locking pin 3 moved out of recess 5 of rosette 1 with axial displacement of building cylinder 6.

In Figure 1 the locking pin 3 is shown in its rest position, i.e. that the locking pin 3 is disengaged from the recess 5 of the rosette 1. The building cylinder 6 is by the appropriate amount compared to his Position in Figure 3 extended from the hand lever 2. In this position, further displacement of the building cylinder 6 is prevented by a locking pin 10 which can be moved within an elongated hole 11 of an insert part 12 inserted into the hand lever 2.

A complete pulling out of the building cylinder 6 from the hand lever 2 is therefore not possible.

In Figures 2, 6, 7 and 8 is an embodiment of the innovation shown, in which a U-shaped leg spring 14 is provided as a locking mechanism. One leg 14a is provided to secure the operative position of the locking pin 3, while the other spring leg 14b is provided to prevent the building cylinder 6 from being pulled out of the hand lever 2 completely.

With spring legs 14a and 14b grip at different heights into that recess 8 of the building cylinder 6, which in turn the lock bit 9 is provided. By actuating the lock bit 9 Both spring legs 14 a and 14 b can be disengaged, so that there is the possibility of excluding the With the spring leg 14b, if necessary, the building cylinder 6 can also be pulled completely out of the hand lever 2. However, as already mentioned, this is only possible if the building cylinder 6 is actuated by means of a key becomes what under normal circumstances only an authorized person can do is.

In the figures 9 to 13 a particularly advantageous embodiment of the innovation is shown.

In this exemplary embodiment, the displacement path of the building cylinder 6 is analogous to the exemplary embodiment according to FIGS 6 to 8 limited by a leg spring 14 with two spring legs 14a and 14b. Here is the spring leg 14b, which is the complete Pulling out of the building cylinder 6 from the hand lever 2 prevented, designed so that it does not get out of the by actuation of the key bit 9 Recess 8 of the building cylinder 6 can be excluded. One full constant removal of the building cylinder 6 from the hand lever 2 is so not possible despite actuation of the key bit 9.

In order to still be able to remove the construction cylinder 6 from the hand lever 2 in the event of repairs or other assembly work that may become necessary without dismantling the entire rotary handle, the hand lever 2 a bore 15 is provided through which a pin 16 can be inserted. The spring leg 14b can be removed from the recess by means of the pin 16

of the building cylinder 6 are levered out, so that now the removal of the building cylinder 6 from the hand lever 2 is possible.

In the exemplary embodiment of the innovation according to FIGS. 9 to 13 the locking pin 3 is arranged in a housing 17 which is screwed into the hand lever 2 and which also accommodates the spring 4. the Leg spring 14 is attached in hand lever 2 so that it cannot rotate.

This construction makes it possible to replace the building cylinder 6 without changing the position of the other functional parts such as locking pin 3, spring 4 and the leg spring 14 acting as a locking mechanism can change.

Common to all the exemplary embodiments is the construction principle, that the locking pin 3 by axial displacement of the building cylinder 6 is operated.
