COUPLING DEVICE FOR ACTUATING A LOCK CYLINDER VIA A KNOB ASSEMBLY

摘要

The invention relates to a coupling device for actuating a lock cylinder via a knob assembly, having two concentric turning parts (2, 1) designed as inner and outer turning parts, the turning parts being guided one into the other, wherein the outer turning part (1) is connected to the key bit and the inner turning part (2) is connected to a knob of the knob assembly, and coupling means work between the inner and outer turning parts (2, 1), the coupling means having locking pins (6) and at least one slider-like release element (4) which takes up different operation positions. According to the invention, the release element (4) carries out one movement in one direction to achieve each operation position, the direction differing from the longitudinal orientation of the turning parts (2, 1). In addition, bores (5) are present in the inner turning part (2) for receiving locking pins (6) which are pretensioned by spring, wherein the release element (4) enables the locking pins (6) to penetrate the inner turning part (2) when in a first operation position, and when in a second operation position, the same inhibits this penetration. The other turning part (1) has a stepping on the inner side thereof, the stepping having a surface running transverse to the penetration direction of the locking pins (6), the surface of which is designed as a locking contour (8).
