Safety devices for firearms
First Claim
1. A safety lock for a firearm having a slide and a striker which is movable relative to the slide to fire a cartridge, the safety lock comprising:
- a lock plate having a non-round bore penetrated by the striker;
a locking element rotatably mounted on the striker to immobilize the striker sufficiently to prevent firing of a cartridge, the locking element having at least one radial projection, a combined outer contour of the at least one radial projection and the striker being complementary to the non-round bore of the lock plate such that the locking element can only pass into the non-round bore when the locking element is positioned in a predetermined angular position; and
at least one pushbutton accessible on the outside of the firearm and operatively coupled to the locking element to rotate the locking element around the striker to unlock the safety lock.

Abstract
Safety devices for firearms have been disclosed. A disclosed safety device comprises a lock plate having a non-round bore penetrated by a striker. Is also includes a locking element rotatably mounted on the striker to immobilize the striker sufficiently to prevent firing of a cartridge. The locking element has at least one radial projection. A combined outer contour of the at least one radial projection and the striker is complementary to the non-round bore of the lock plate such that the locking element can only pass into the non-round bore when the locking element is positioned in a predetermined angular position. The safety device also includes at least one pushbutton accessible on the outside of the firearm and operatively coupled to the locking element to rotate the locking element around the striker to unlock the safety lock.

10. A firearm comprising:
-
a slide;
a safety lock located within the slide, the safety lock having a locked state wherein the safety lock precludes firing of the firearm and an unlocked state wherein the safety lock does not preclude firing of the firearm, the safety lock entering the unlocked state upon entry of a combination; and
a plurality of pushbuttons accessible from external to the slide to enter the combination, wherein no symbols representative of the combination are visible external to the firearm.

11. For use in retrofitting a firearm, a slide comprising:
-
a striker located within the slide;
a safety lock located within the slide, the safety lock having a locked state wherein the safety lock precludes firing movement of the striker and an unlocked state wherein the safety lock does not preclude firing movement of the striker, the safety lock entering the unlocked state upon entry of a combination; and
a plurality of pushbuttons accessible from external to the slide to enter the combination, wherein no symbols representative of the combination are visible external to the slide.

12. A firearm comprising:
-
a slide;
a safety lock located within the slide, the safety lock having a locked state wherein the safety lock precludes firing movement of the striker and an unlocked state wherein the safety lock does not preclude firing movement of the striker, the safety lock including a plurality of counters which place the safety lock in the unlocked state when predetermined values are respectively counted by the counters; and
a plurality of pushbuttons accessible from external to the slide to toggle respective ones of the counters to unlock the safety lock. - View Dependent Claims (13, 14, 15, 16)

17. For use in a firearm having a slide and a striker, a safety lock comprising:
-
a star wheel rotatably mounted within the slide, the star wheel defining a keyhole, the angular position of the keyhole being selected by the angular position of the star wheel;
a locking element rotatably mounted on the striker, the locking element having a projection dimensioned to pass through the keyhole when the projection and keyhole have a same angular position;
a ratchet wheel coupled to the locking element for rotation therewith;
a release lever cooperating with the ratchet wheel to releasably secure the locking element against rotation;
a pushbutton accessible exterior to the slide to rotate the ratchet wheel and the locking element a predetermined distance each time the pushbutton is depressed; and
a reset spring biasing the ratchet wheel and the locking element toward a zero position, wherein the angular position of the star wheel defines a number of times the pushbutton must be depressed to place the locking element in the same angular position as the star wheel. - View Dependent Claims (18, 19, 20, 21)
