Abstract:
A trigger lock (1) for use on a firearm having a trigger and a trigger guard, with the firing of said firearm being initiated by the rearward movement of said trigger, said lock comprising:a plurality of pins (2) cooperating to prevent initiation of movement by said trigger, with one or more of said pins being movable between a first and a second spaced apart position, wherein in said second position said trigger movement is restricted by having one of said pins placed against a position on the rear portion of said trigger and another of said pins placed in a spaced apart relationship and against a position on the inside of said trigger guard and behind said trigger, a means (3) for moving and holding one or more of said pins in said spaced apart relationship so as to resist the rearward movement of said trigger, a means (4) for locking said pins (2) in said spaced apart relationship, wherein said means (3) for moving and holding one or more said pins in said spaced apart relationship comprising: a first base (10) configured to have a top (12), an adjoining upper side (14), an adjoining ledge (16) and an adjoining lower side (18) surface, said upper side surface having an elongated groove (20), said first base (10) further having a cavity (22) configured so as to have a top opening (24) through said ledge (16) surface and a side opening (17) through said lower side (18) surface, a latch plate (30) having a top (32), a side (34) and a bottom (36) surface, said side surface (34) having a finger (38) configured to fit within said elongated groove (20) so that said plate side (34) is slidably mounted on said first base upper side (14), a portion of said plate bottom (36) surface having a toothed section (40), a keeper plate (50) having a top (52), a side (54) and a bottom (56) surface, said side (54) surface having an arm (58) extending from said side (54), a portion of said top (52) surface having a toothed section (60) configured to mesh with said plate toothed section (40) so as to restrict relative motion between said keeper (50) and latch (30) plates, said keeper plate (50) configured so as to fit within said cavity (22) and to be movable between a locked and an unlocked position, wherein, when in said locked position, said keeper plate toothed section (60) extends through said cavity top opening (24) in order to mesh with said latch plate toothed section (40), a means (70), configured to fit between said keeper plate arm (58) and an adjoining wall of said cavity (22), for biasing said keeper plate (50) for motion between said locked and unlocked positions, a second base (80) having a top (82), an adjoining side (84) surface and an opposite side (86) surface, said adjoining side surface (84) configured so as mate with said first base upper side (14), ledge (16) and lower side (18) surfaces to hold said latch plate finger (38) within said elongated groove (20) and to hold said keeper plate (50) within said cavity (22), said adjoining side (84) and opposite side (86) surfaces having extending there between a passage (88) that provides access through said side opening (17) to said cavity (22) and said keeper plate (50), and wherein said passage (88) configured to allow for said locking means (4) to exert a force upon said keeper plate (50) so as to move said plate to its locked position.
