Abstract:
A hinged lock key comprising a bow and a shank, in which the bow is hinged with respect to the shank and moves between a working position in which a longitudinal plane of the bow is substantially parallel to a longitudinal plane of the shank and a folded position in which the longitudinal plane of the bow is substantially perpendicular to the longitudinal plane of the shank, and in which a snap-fastening connection is provided which keeps the working position stable and enables the folded position to be reached when the shank is positioned in a lock by overcoming a given force, wherein two opposite transverse arms, on which the bow is hinged, extend from the shank and in that the snap-fastening connection acts between the bow and arms and wherein the bow includes a rigid core which is hinged on the arms and is embedded in an elastic casing to apply a resistive force against the rigid core during rotation of the shank relative to the bow.
