Abstract (en)

A safety lock comprises a lock-bolt element (3), which can be controlled by means of a cylinder lock. The actuation of the latter by means of a key sets in rotation a radially extending control member (13), which is received in a radial slit of a ring gear (10) mounted so that it can turn coaxially with respect to the rotor of the cylinder lock. The rotation of the control member (13) impressed by the key then brings about a rotation of the ring gear (10). A mechanical transmission (7), including at least one gear (9) meshing with the ring gear (10), converts the rotation of the ring gear (10) into a rectilinear sliding of the lock bolt (3). In any point of the mechanical transmission (7) a coupling is provided between a driven member and a driving member that affords said members the possibility of a limited relative movement. Consequently, the movement of said driving member is transmitted to said driven member only after said members have reached one of their two relative end positions.
