Abstract

Abstract In one embodiment, the detachable gun trigger safety device includes a threaded bolt assembly having a longitudinally extending threaded shank and a curved bolt head adapted to receive a portion of the rear housing of a gun trigger guard. The device also includes a mating lock nut threadably received on that shaft and having a front surface adapted to bear against the rear of a gun trigger. The front surface of the nut includes a groove adapted to receive the rearwardmost curved surface of the trigger. The device is designed to span the space between a gun trigger and the rear portion of that gun's trigger guard and wedge the trigger forward to prevent its rearward movement and firing of the gun. The lock nut may include a number of spaced protrusions in its front surface to help resist turning of the nut when tight against the trigger. The nut may be knurled to facilitate turning on the shaft and the shaft may have one or more cotter pins holes transversely therethrough. The bolt head may have a curved central groove flanked by side flanges to assist in seating and retaining the bolt against the rear portion of the gun trigger guard. In another embodiment, the device may be a notched rubber ball, with or without an expansion bolt, or a two-piece expandable slip box.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 73 words
An improved detachable gun trigger safety device, said device comprising, in combination: (a) a gun trigger; (b) a trigger guard disposed around and spaced from the front and rear of said trigger; and, (c) an elastomeric ball which expands in one direction while it compresses in another direction, said ball being wedged between the rear of said trigger and the rear portion of said trigger guard to block rearward movement of said trigger.
Claim 2
Dependent Claim 73 words
An improved detachable gun trigger safety device, said device comprising, in combination: (a) a gun trigger; (b) a trigger guard disposed around and spaced from the front and rear of said trigger; and, (c) an elastomeric ball which expands in one direction while it compresses in another direction, said ball being wedged between the rear of said trigger and the rear portion of said trigger guard to block rearward movement of said trigger.
Claim 3
Dependent Claim 30 words
The improved device of claim 1 wherein said ball is notched at opposite ends, thereby firmly seating against the rear of said trigger and the rear portion of said guard.
Claim 4
Dependent Claim 51 words
The improved device of claim 1 wherein said ball includes a bolt passing transversely therethrough, with a compression plate on one end of said bolt and a nut on the opposite end thereof for compressing said ball transversely while elongating it longitudinally for a tighter fit with said trigger and guard.
Claim 5
Dependent Claim 116 words
An improved gun trigger safety device, said device comprising, in combination: (a) a gun trigger; (b) a trigger guard disposed around and spaced from said trigger; and, (c) a safety component wedged between the rear of said trigger and the adjacent rear portion of said guard, said safety component comprising, in combination, an elongated box with an open end out through which a plate telescopes longitudinally, said box and plate bearing a plurality of transverse holes extending therethrough and spaced along the length thereof, and a bolt disposed in holes aligned in said box and plate to releasably tightly hold said component against the rear of said trigger and the adjacent rear portion of said guard.
Claim 6
Dependent Claim 116 words
An improved gun trigger safety device, said device comprising, in combination: (a) a gun trigger; (b) a trigger guard disposed around and spaced from said trigger; and, (c) a safety component wedged between the rear of said trigger and the adjacent rear portion of said guard, said safety component comprising, in combination, an elongated box with an open end out through which a plate telescopes longitudinally, said box and plate bearing a plurality of transverse holes extending therethrough and spaced along the length thereof, and a bolt disposed in holes aligned in said box and plate to releasably tightly hold said component against the rear of said trigger and the adjacent rear portion of said guard.
Claim 7
Dependent Claim 31 words
The improved device of claim 4 wherein said box and plate are notched at selected ends thereof, thereby securely engaging said rear of said trigger and rear portion of said guard.
