Abstract
In a semi-automatic firearm is a simplified firing mechanism that includes a manual safety system and a doubly redundant automatic safety system. The firing mechanism includes a trigger, a trigger bar, a trigger lever, a firing pin safety, spring loaded striker with a firing pin, a sear, a dislocator and a manual safety. When the manual safety is in the safe position the striker is blocked and the trigger bar is disengaged from the sear and the dislocator. If the manual safety is in the firing position, but the trigger has not been fully released after each discharge, the trigger lever cannot move the firing pin safety out of the way of the striker, and the trigger bar cannot move the sear.
Claims21
A fail safe system for a hammerless, semi-automatic firearm, comprising:
- a frame, including a barrel having a breech for receiving a cartridge, a slide longitudinally moveable in a cycle between an at battery position adjacent to the breech and a full recoil position distal to the breech, a reciprocating spring loaded firing mechanism biased for striking the cartridge, and a trigger for releasing the firing mechanism;
- a first automatic safety mechanism operatively connected to the trigger, having a blocking member positioned between the firing mechanism and the breech, the blocking member being biased to a firing mechanism blocking position and moveable to a firing mechanism passing position, the first automatic safety mechanism further having a blocking member connector, operatively associated with the trigger for moving the blocking member to the passing position only when the slide is in the at battery position and only after the trigger has been fully released;
- and
- a second automatic safety mechanism operatively interconnected to the trigger and the firing mechanism, having a first disengagement device for disconnecting the trigger from the firing mechanism when the slide is not in the at battery position, and having a second disengagement device for disconnecting the trigger from the firing mechanism by dislocation after a cycle until the trigger is fully released, whereby the firearm can not be accidentally discharged after a cycle until the trigger is fully released and the cycle is fully completed.

- and

- a frame, including a barrel having a breech for receiving a cartridge, a slide longitudinally moveable in a cycle between an at battery position adjacent to the breech and a full recoil position distal to the breech, a reciprocating spring loaded firing mechanism biased for striking the cartridge, a trigger connected to a trigger bar and a sear operatively interconnecting the trigger bar to the firing mechanism for releasing the firing mechanism when the trigger is depressed;
- a first automatic safety mechanism operatively connected to the trigger, having a blocking member positioned between the firing mechanism and the breech, the blocking member being biased to a firing mechanism blocking position and moveable to a firing mechanism passing position, the first automatic safety mechanism further having a blocking member connector, operatively associated with the trigger for moving the blocking member to the passing position only when the slide is in the at battery position and only after the trigger has been fully released;
- a second automatic safety mechanism operatively interconnected to the trigger and the firing mechanism, having a disengagement device for disconnecting the trigger from the firing mechanism when the slide is not in the at battery position;
- and
- a manually operated safety mechanism operatively interconnected with the firing mechanism and the trigger bar, the manually operated safety mechanism having an external lever for moving the manually operated safety mechanism between a safe and a ready to fire position and having means for rearwardly displacing and blocking forward motion of the firing mechanism and simultaneously disengaging the trigger bar from the sear when the manually operated safety mechanism is in the safe position, whereby the firearm can not be accidentally discharged after a cycle until the trigger is fully released and the cycle is fully completed.
