View Patent ↗A handheld finger activated semi-automatic arm may include a barrel, a trigger, a moveable gun bolt and a trigger reset mechanism. The trigger reset mechanism may use rigid mechanical contact between the trigger and the gun bolt during an earliest portion of the operating cycle. The trigger may be blocked from depression by the gun bolt up to 99% of the operating cycle.
1. A handheld finger activated semi-automatic arm comprising:
a frame;
a chamber face that is supported to the frame and that comprises a barrel;
a trigger that is depressible to fire the arm once per operating cycle;
a gun bolt that is movable rearward and forward with respect to the frame;
a trigger reset mechanism comprising rigid mechanical contact between the trigger and the gun bolt during an earliest 50% of the operating cycle; and,
wherein the trigger is blocked from depression by the rigid mechanical contact between the trigger and the gun bolt up to 99% of the operating cycle.
2. The handheld finger activated semi-automatic arm of claim 1 further comprising:
a safety lock that engages a sear surface on a disconnector to prevent trigger depression.
3. The handheld finger activated semi-automatic arm of claim 1 further comprising:
a striker having an integrated sear surface;
a striker biasing member that biases the striker toward a forward position;
a disconnector having: a first sear surface in contact with the striker sear surface; a second sear surface; and, a pivot that is rearward of the striker sear surface and forward of the disconnector second sear surface;
a safety lock that is adjustable between: a locked condition which prevents the trigger from being depressed and an unlocked condition which permits the trigger to be depressed;
wherein the safety lock contacts the disconnector second sear surface when the safety lock is in the locked condition;
wherein the safety lock is out of contact with the disconnector second sear surface when the safety lock is in the unlocked condition; and,
wherein the arm is operable when the safety lock is in the unlocked condition by depressing the trigger to pivot the disconnector about the disconnector pivot, to move the first disconnector sear surface out of contact with the striker sear surface, to enable the striker biasing member to force the striker to fire the arm.
4. The handheld finger activated semi-automatic arm of claim 1 further comprising:
a striker having an integrated sear surface;
a striker biasing member that biases the striker toward a forward position; and,
wherein when the gun bolt is moving forward the striker compresses the striker biasing member.
5. The handheld finger activated semi-automatic arm of claim 1 further comprising:
a striker having an integrated sear surface at a rearward end;
a striker biasing member that is positioned above or beside the striker from a lengthwise perspective; and,
wherein the striker and striker biasing member are charged only as the gun bolt moves forward toward the chamber face.
