<p>A ring (2) turns at a set point in a cylindrical unit (1), and has protrusions (3) on its inside periphery, in the bolting assembly for a door, or lid on a case. A sliding bar (4) in the cylinder has a concave groove (5) with sides forming saw-toothed guides (7, 8) with offset teeth. Sliding grooves (6) connected to a guide, and closed at the other end, are formed to run axially on the bar, with the protrusions engaging them. A magnet (9) at the other end of the bar has the bar stressed towards it by a spring (11) on the cylindrical unit.</p> |
