ABSTRACT:
A trigger lock for firearms wherein a pair of discs loosely connected together by a flexible band are adapted to be positioned one on each side of the trigger guard of a firearm. When pushed towards each other, a pair of tapered spring detent arms fixed to the internal face of the first of said discs engage in a pair of apertures in the second of said discs from which they may be disengaged by finger pressure. A central hocking pin positioned centrally on the second of said discs engages with a central tumblered locking receptacle positioned centrally on the internal face of the first of said discs and locks into place therein. The external face of the first of said discs carries a circularly arranged set of numbers, e.g. 1 through 8, and a knob mounted on the outer end of the central locking receptacle. The knob carries an indicating pointer and when rotated to a preset two-numbered combination causes the tumblers within such central locking receptacle to disengage from the locking grooves on the locking pin freeing such pin to be withdrawn when the tapered detent arms are also disengaged, thus allowing removal of the trigger lock assembly from the firearm.
