description ι

The invention relates to a lock cylinder fastening device for fastening lock cylinders, in particular in furniture parts, according to the preamble of the claim

Known fastenings of locking cylinders are e.g. by screwing on by means of a flange on the outer cylinder ^ according to DE-OS 19 12 164 ,. wherein the lock cylinder is to be inserted from the rear of the furniture part.

Lock cylinders to be inserted into the furniture part from the front are known, for example, from DE-OS 15 53 621, in which the front surface has a collar to stop against the furniture part and the Outer cylinder has a thread on which the lock cylinder against the furniture part by means of a nut can be braced.

This has the advantage that the possibly unclean hole in the furniture part is covered, but the disadvantage of complex assembly.

On this basis, the invention is based on the object of creating a lock cylinder fastening device, for a lock cylinder that is inserted from the front of the furniture part into its bore or cut-out.

ti ■ * *

bar and that from the back of the furniture part by means of a captive rotary actuation in the hole or cutout can be fastened. Included the attachment should be independent of the thickness or wall thickness of the furniture part.

This object is achieved by the features of the characterizing part of claim 1. This has the advantage that the fastening element is integrated into the lock cylinder Part is that by adjusting means, e.g. a Screw can be moved into the locking position and vice versa.

The further claims relate to advantageous configurations of the article according to claim 1.

Two exemplary embodiments are shown in the drawings. It shows

1 shows the first exemplary embodiment in side view, partly in the cut,

FIG. 2 is a view according to FIG. 1,

3 shows the second embodiment in side view, partly in the cut,

FIG. 4 shows a view a according to FIG. 3i

The attachment according to the invention extends to the actual outer cylinder 1 and its operation 2, which is why the representation of the inner cylinder can be straightened out.

There is a recess in the outer cylinder 1 and the bottom 2 3, 4 worked out for the fastening element, which according to the first exemplary embodiment is a leaf spring 5 is. This leaf spring 5 has on the one hand an angled pressure surface 6 from which Guide arms 7 extend into recesses 8 in 3oden 2. The leaf spring has at its other end a claw 9, which can also be turned up on the side. In a threaded hole in the bottom 2 is a Adjusting screw 10 is arranged, which acts against the pressure surface 6 of the leaf spring 5.

If the adjusting screw 10 is now screwed in, the leaf spring 5 moves in the recesses 3, 4 and is guided to the outside via the slope 3a. The claw 9 penetrates the material of the lock cylinder surrounding furniture part and braced it in the recess of the Mönel part.

After loosening the adjusting screw 10 k => nn the locking cylinder be pressed out of its recess, the leaf spring 5 being returned to its outlet will.

According to the second embodiment, the fastening element is a wedge 11, which in corresponding Recesses 12, 13 in the outer cylinder and its bottom 2 is displaceably arranged. A threaded sleeve 14 is formed on the wedge 11, through which a threaded pin 15 passes is. The threaded pin 15 is immovable but rotatable in the recesses 12, 13 in the longitudinal direction arranged so that the wedge 11 is displaced when the threaded pin 15 is rotated.

When it is moved, the wedge 11 rises above the slope 12a of the recess 12 to the outside and clamps the lock cylinder in the recess of the furniture part. The wedge preferably has 11 Longitudinal profiles 16 which claw into the wall of the recess in the furniture part. The threaded pin 15 is accessible via an opening 17 in the base 2.

By tensioning the lock cylinder in the recess of the furniture part by means of the leaf spring 5 or the wedge 11, the lock cylinder attachment is independent of the respective thickness or wall thickness of the furniture part.
