Abstract

Locking mechanism of a hand firearm consisting of a breech block (1) with a longitudinally slidingly arranged firing pin (33) and provided on its upper side with a carrier (2) having a stepped through hole (3), inside which a return spring (5) is arranged on a guide bar (4), and further with a single arm transmission lever (37), which is swingingly arranged in the carrier (2) and the free end of which is adapted for an engagement with a cross trip (47) provided in a cutoff case (7). The locking mechanism has got the single arm transmission lever (37) provided with a cylindrical crossbar (38), which is swingingly and slidingly arranged in an oval cross seat (40) in the carrier (2) and which is provided with a back supporting surface (41) and a front supporting surface (42) for an engagement with the cylindrical crossbar (38) of the single arm transmission lever (37), wherein the free end (43) of the single arm transmission lever (37) is provided with a cross stop (44) overlapping on both sides and having an engagement surface (45) for an engagement with a stop surface (46) of the cross trip (47), and a locking clearance (X) exists between the engagement surface (45) and the stop surface (46).

Claims (3)

1. Locking mechanism of a hand firearm consisting of a breech block (1) with a longitudinally slidingly arranged firing pin (33) and provided on its upper side with a carrier (2) having a stepped through hole (3), inside which a return spring (5) is arranged, and further with a single arm transmission lever (37), which is arranged in the carrier (2) and the free end of which is adapted for an engagement with a cross trip (47) provided in a cutoff case (7), characterised in that the single arm transmission lever (37) is provided with a cylindrical crossbar (38), which is swingingly and slidingly arranged in an oval cross seat (40) in the carrier (2) and which is provided with a back supporting surface (41) and a front supporting surface (42) for an engagement with the cylindrical crossbar (38) of the single arm transmission lever (37), wherein the free end (43) of the single arm transmission lever (37) is provided with a cross stop (44) overlapping on both sides and having an engagement surface (45) for an engagement with a stop surface (46) of the cross trip (47), and a locking clearance (X) exists between the engagement surface (45) and the stop surface (46).
2. Locking mechanism of a hand firearm according to claim 1, characterised in that the overlapping cross stop (44) of the single arm transmission lever (37) is further provided with a control surface (48) for an engagement with a nose (49) of a single arm release lever (50) for catching the hammer (55) by its catch protrusion (54).
3. Locking mechanism of a hand firearm according to claim 1, characterised in that the single arm transmission lever (37) is provided with a firing element (59) arranged in a limited sliding way, having an end intended for an engagement with the firing pin (33) and the opposite end for an engagement with the striking surface (58) of the hammer (55).
