<p>A lever (19) of a lock is hinged at one of its extremities to a transverse pin (18) carried by a rotary shaft (13) for controlling a locking bolt (16). The free extremity (22) opposite to the lever (19) co-operates with a lock (23) pivotally mounted on a transverse pin (24). In the locking position of the lock (23), the latter holds the lever (19) nested in a housing (21) of the base of the lock assembly. Unlocking of the lock (23) by rotation of the key (28) causes, due to the action of a return spring (30), pivoting motion of the lock (28) and the release as well as the withdrawal of the free and (22) from the housing (21).</p> |
