ABSTRACT:
The handcuff assembly includes a bow pivotally connected to a cheek plate frame assembly which includes a unitized frame that is die stamped from a single metal plate and which is overmolded with a polymer overmold. The unitized frame has interlocking tabs on folded side plates of a base frame. A removable lockset assembly for locking a pawl relative to ratchet teeth on the bow and including a slideable lock bar is received in the base frame. A key receiving structure on each side of the lockset assembly is provided for receiving a key and enabling the key to turned in one direction only for first unlocking a double-lock, which prevents movement of the bow in either direction and for secondly, completely unlocking the handcuff by moving the pawl away from the bow and against a spring mechanism. Beveled lock slots and keyways are provided in opposite flat side walls of the base frame for facilitating insertion of a handcuff key into the lockset assembly in the base frame. An easily deflectable detent is provided on a lockset housing for releaseably locking the lockset assembly within the base frame of the cheek plate assembly.
