发明名称 Detachable gun trigger safety device
摘要 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.
