Patent ID: 7251964

Claim:
A double locking handcuff comprising: a housing having an interior cavity; a bolt pivotally disposed in the housing interior cavity and having an upper head portion extending into said housing interior cavity and an opposed lower surface; a jaw operably connected to the housing having a generally arcuate outer surface with a geometry configured to cooperatively engage said lower surface of said bolt; a spring disposed in the housing interior cavity and configured for biasing the bolt against the jaw when the jaw is brought into cooperation with the bolt, wherein the spring is laterally shiftable within said interior cavity between a single-lock position allowing the bolt to disengage from the jaw upon the application of a force overcoming the biasing effect of the spring and a double-lock position preventing the bolt from disengaging from the jaw; and a manually depressible cam pivotally attached to said housing, said cam having an outer surface configured for manual engagement and an actuating surface opposed to said cam outer surface for engaging said spring wherein rotation of said cam laterally shifts said spring from the single-lock position to the double-lock position within said housing interior cavity.
