Two contrarily moving slide bars (7,11) are positioned near the lock plate (5). A cog wheel or pinion (2) grips the slide bars diametrically and is pivot mounted in a housing (1) and turns in both circumferential directions by means of a nut (3) and pusher. The slide bar fitting into the cog wheel on the side facing away from the lock plate, or the slide bar attachment (10) fitting into the cog wheel on the toothed (8) side, together with the slide bar, grips round the cog wheel or pinion in a U shape. |
