  • Patent number: 3979850
    Abstract: There is disclosed a handgun intended for one-time use for launching a projectile. The gun is stored in a condition wherein a handle of the gun is folded to cover the trigger. A releasable locking member locks the handle in its folded position. In its folded position, the handle biases a pair of knobs inwardly to prevent actuation of the trigger, while a portion of the trigger engages the firing pin to prevent movement of the firing pin. In the stored condition of the handgun, the firing pin is uncocked and is unable to be moved into a cocked position. The locking member has a guide portion which is slidable within a bore containing the firing pin and its biasing spring. The guide portion acts as an abutment and a guide for the rear end of the spring. In one embodiment of the invention, the locking member is cammed inwardly by the handle as the handle is unfolded, to automatically cock the firing pin spring.
