Abstract:
A locking mechanism having an enclosed striker assembly, comprising:A) a firing pin assembly having a shaft with first and second ends, said first end having a leg extending radially outwardly a first predetermined distance and said second end including a firing pin, said firing pin assembly further includes a stopper surface on said shaft at a second predetermined distance from said second end and a spring member receiving said shaft therethrough, and said spring member includes third and fourth ends, said third end coacts against said stopper surface and said fourth end includes a bushing rigidly mounted thereon that in turn coacts with said leg keeping said spring member biased against said stopper surface and said leg; B) a spacer sleeve assembly having fifth and sixth ends and a longitudinal stepped notch extending from said fifth end towards said sixth end a predetermined distance without reaching said sixth end, said stepped notch includes an end edge closest to said sixth end and a stepped edge located at a third predetermined distance from said end edge, said fifth end having cooperative dimensions to coact with said bushing and selectively causing said spring member to compress, and said sixth end including a protrusion with a unique shape axially mounted thereon; C) a keyed plate assembly having inner and outer walls and a central through opening, said inner wall including at least two cutouts with mating cooperative characteristics to receive said protrusion in at least two angular positions of said spacer sleeve assembly; and D) means for rotating said spacer sleeve assembly through said through opening so that said leg is selectively brought in alignment with said stepped edge thereby restricting the travel of said shaft and in alignment with said end edge having unobstructed travel that permits the operation of a pistol.
