Abstract
A locking system for a pistol firing pin integrated within the firing mechanism of a semiautomatic pistol is composed fundamentally of a single part, called a tilting lock (1). The tilting lock (1) is duly housed in a slot (9) located in the lower part of bolt (10) and rotates about a shaft (8) fixed to the bolt itself (10). The lock (1) engages a notch (12) in firing pin (11) by the action of a spring (17) inserted in the slot (9) of bolt (10) and is disabled only at the instant of firing by the action of the projection (16) formed in the shoulder (15) of the arm (14) of the pistol's trigger (13).
Claims6
A locking system for a firing pin integrated into the firing mechanism of a semi-automatic pistol having a firing pin (11), a bolt (10), a trigger (13) and a trigger arm (14), said locking system comprising a lock (1) rotatably mounted in a slot (9) in a lower part of said bolt (10) about a shaft (8) that is perpendicular to a longitudinal axis of said pistol such that said lock (1) can turn freely about said shaft (8), said lock (1) having an upper contour formed by an arc of a circle (2) concentric with a hole (3) intended for passage of said shaft (8) therethrough, formed by a first straight line (21) tangent to said arc of the circle (2) on one end of said arc, and formed by a second straight line (23) tangent to said arc of the circle (2) on the opposite end of said arc, thus forming two convergent straight lines, which define the upper contour of an upper larger arm (4) of said lock (1) and a lower smaller arm (6) of said lock (1), respectively.
