Abstract:
A handcuff design is provided, including a handcuff strand having ratchet teeth with openings formed therein, a ratchet button comprising teeth configured to interface with the openings formed in the handcuff strand, a universal handcuff key receptacle configured to receive a universal handcuff key, a pawl arrangement including a rotatable pawl element configured to be moved in a direction away from the handcuff strand by the universal handcuff key, the pawl arrangement including a spring mechanism, and a lock bar configured to impede movement of the pawl arrangement unless moved to an unlocked position. Unlocking the handcuff requires digitally actuating a first of the pair of ratchet buttons concurrently with digitally actuating a second of the pair of ratchet buttons while simultaneously employing the universal handcuff key, thereby releasing the ratchet teeth of the handcuff strand.
