ABSTRACT:
A gun trigger mechanism that helps prevent accidental discharge of a gun, including a spring-loaded hammer retainable in a fully-cocked position, from which it may be fired, or a half-cocked position, at which it may be loaded and unloaded, but not fired, by engagement between a trigger sear and a hammer sear or a half-cocked notch, respectively, preferably including an interlock, hidden within the gun's frame, a trigger spring biasing the interlock towards a locked position, where it provides a blocking interface between the hammer and the gun's frame. A hammer blocking arm, on the interlock swinging end, rides generally between and against two frame shoulders when the hammer is near a firing position and the trigger is not being pulled. The hammer blocking arm and the swinging end of the interlock are moved down and forward, away from the frame shoulders when the trigger is pulled. A hammer shoulder mounted on a lower end of the hammer must move toward and between the frame shoulders for the hammer to reach the firing position. Unless the trigger is pulled, the gun cannot be fired. As the hammer is biased to an at-rest position, away from the firing position, the interlock is biased upward to its locking position. In its normal, uncocked state, the hammer cannot be fired by accidental bumping of the hammer. Alternatively, it is also preferable that removal of the hidden interlock prevents safe and normal operation of the trigger.
