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 a guide extending radially a second predetermined distance, said second end including a firing pin, said firing pin assembly further includes a stopper surface on said shaft at a third 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 first spacer sleeve assembly rigidly mounted thereon that in turn coacts with said guide and leg, keeping said spring member biased against said stopper surface and said first spacer sleeve; B) a second spacer sleeve assembly having fifth and sixth ends and longitudinal cutouts extending from said fifth end towards said sixth end a fourth predetermined distance without reaching said sixth end, said fifth end having cooperative dimensions to coact with said first spacer sleeve 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 second spacer sleeve assembly; and D) means for rotating said second spacer sleeve assembly through said through opening so that said guide and leg are selectively brought in alignment with said fifth end thereby restricting the travel of said shaft and in alignment with said cut-outs having unobstructed travel that permits the operation of a pistol.
