Abstract
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.
Claims9
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 the firing pin (6) does not interfere with a bullet loaded in the barrel (2), and a forward position, at which the firing pin (6) is in abutment against the bullet loaded in the barrel (2), in order to activate a primer thereof;
- and
- a drive mechanism (5) of the firing pin (6), comprising 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 a user's thumb,
- the drive mechanism (5) comprises, in addition to the trigger (T):
- a drive shaft (8) fixed to the trigger (T) and rotating on rotation axis (Y) thereof,
- 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 thrust cam (9) thereby rotationally pushing the main lever (10) in an opposite way, and
- wherein the rotation of the main lever (10) leads to a corresponding roto-translation of the thrust lever (12), the thrust lever (12) rotationally pushing the snap lever (13) up to cause disengagement thereof from the firing pin (6).
11 more elements
A rifle (100, 200) comprising:
- a main body;
- a barrel (102, 202) and a butt (103, 203), both constrained to the main body;
- a firing pin (6) translatable in a corresponding seat of the main body between a backward position, at which the firing pin (6) does not interfere with a bullet loaded in the barrel, and a forward position, at which the firing pin (6) is in abutment against the bullet loaded in the barrel, in order to activate a primer thereof;
- and
- a drive mechanism (105, 205) of the firing pin (6), comprising a trigger (T) and levers (106, 113, 206, 213) and/or gears (209) and/or elastic elements,
- wherein the trigger (T) is positioned substantially laterally to the barrel (102, 202) or butt (3), in order to be pressed with a user's thumb,
- wherein the drive mechanism (105, 205) comprises, in addition to the trigger (T), a hammer (106, 206) pivoted to the main body and rotating between an initial position, in which the hammer (106, 206) is held by the trigger (T) directly or by the interposition of other elements (113, 213), and a final position contacting and pushing the firing pin (6), wherein the trigger (T) does not hold the hammer (106, 206), and wherein a preloaded spring pushes the hammer (106, 206) with violence towards the firing pin (6);
- the rifle further comprising at least one safety mechanism inhibiting the drive mechanism, wherein the at least one safety mechanism (15) comprises at least one of:
- a safety lever (17) pivoted to the butt (3) and rotating with respect thereto at a back portion thereof, and an elastic element (19) countering rotation of the safety lever (17), wherein in a first position an end (20) of the safety lever engages a snap lever (13) and prevents the rotation thereof, thereby preventing activation of the firing pin (6) and, in a second position, the safety lever (17) does not engage the snap lever (13), thereby allowing the activation of the firing pin (6), switching from the first to the second position being caused by a user's palm as the user grasps the butt (3), by overcoming the force of the countering elastic element (19);
- a safety button (21) at a front and upper portion of the butt (3), where a user's first finger is expected to be placed, movable between an active position, next which the safety button (21) engages the trigger (T) and prevents the rotation thereof, and an inactive position, corresponding to the button pressed towards the butt (3) by the first finger and to disengagement of the trigger (T), which is therefore free to rotate.
