ABSTRACT:
A hinged lock key has a bow and a shank from which extend two opposite transverse arms on which the bow is hinged and moves between the working position and folded positions; a snap-fastening connection acting between the bow and the arms keeps the working position stable and enables the folded positions to be reached by overcoming a given force. This key structure is inexpensive to produce.
