ABSTRACT:
A latching system comprises a notched post assembly, a post gripping assembly and a handle assembly, and, in preferred embodiments, a lock assembly associated with the handle assembly, wherein the notched post assembly is comprised of an elongated post formed at one end with at least two opposing, axially extending rows of notches or teeth and alternately disposed smooth surfaces and the post gripping assembly comprises a channel for accepting the notched end of the post and comprises movable cam elements which cooperate with the notches of the post to effect the primary latching function of the system; and wherein the unlatching of the post from the channel is accomplished by rotating the post to disengage the notches and the cam elements. A pick-resisting improvement to the cylinder lock assembly includes facial piece defined with a plurality of knobs protruding partly into the key entry passage of the lock assembly.
