| 摘要 |
A firearm (1), for example a pistol or a rifle, is described, wherein the drive mechanism (5) of the firing pin (6) is controlled by a trigger (T), a key or a button, laterally positioned on the firearm (1) and operable by the hand thumb. The firearm, with respect to the known art, is characterized by a reduced aiming distance (d1), which is the distance between the index finger (f1) and the longitudinal axis (X) of the barrel (2). This leads to a reduced recoil. |

1. Firearm (1) comprising:
a main body (B); a barrel (2) and a butt (3), both constrained to the main body; a firing pin (6) translatable in a corresponding seat of the main body (B) between a backward position, at which it does not interfere with the bullet loaded in the barrel (2), and a forward position, at which it is in abutment against the bullet loaded in the barrel (2), in order to activate the primer thereof; and a drive mechanism (5) of the firing pin (6), comprising in its turn a trigger (T) and levers (10, 12, 13) and/or gears (8, 9) and/or elastic elements (15), wherein the trigger (T) is positioned substantially laterally to the barrel or butt (3), in order to be pressed with the hand thumb, the drive mechanism (5) comprises, in addition to the trigger (T): a drive shaft (8) fixed to the trigger (T) and rotating on its rotation axis a thrust cam (9) fixed to the drive shaft (8), a main lever (10) having a first end hinged to the main body (B) of the firearm, a thrust lever (12) pivoted to the main lever (10) at the second end, and a snap lever (13) pivoted to the main body (B) and pivoted to the thrust lever (12) and provided with means (14) for temporarily retaining the firing pin (6), wherein the rotation of the trigger (T) leads to an equal rotation of the drive shaft (8) and of the thrust cam (9), the latter in its turn rotationally pushing the main lever (10) in the opposite way, and wherein the rotation of the main lever (10) leads to a corresponding roto-translation of the thrust lever (12), the latter in its turn rotationally pushing the snap lever (13) up to cause the disengagement thereof from the firing pin (6). |
