Abstract (en)
A locking mechanism for the door of a safe or the like has a bolt strap (1) operated by a thrower (2) and a keyless combination lock (4) whose bolt (5) pivots a lever (8) to block retraction of the strap (1) and thrower (2). The lever (8) is also connected through a rod (11) to a shutter for blocking the entrance to a separate key lock (not shown). In order to relieve the force acting inwards on the bolt (5) when it is thrown there is provided a spring (19) connected at one end (23) to the lever (8) and at its other end (17A) to another pivoted lever (17), the arrangement being such that the spring (19) goes overcentre to apply a force to the bolt (5) in the same sense as its throwing movement whenever the latter is thrown. <IMAGE>
