Abstract

An automatic submachine gun for exploiting recoil, comprises: a stock (2); a fixed barrel (4); a grip (3) provided with an extractable butt (20); a bolt (6) sliding in direction parallel to the longitudinal axis of the barrel (4) inside the stock (2) for locking the breech of the barrel (4); a device for recovering the recoil kinetic energy of the bolt (6); a hammer (22) swinging in opposition and through the action of a spring actuator element (23) between a cocked position and an uncocked position; a trigger assembly for the hammer (22) comprising in turn a swinging trigger (21) pivoted on the stock (2) and operatively connected to a sear lever (26), an opposing lever (28) of the hammer (22) for single shot fire actuatable by the sear lever (26), and an opposing lever (29) of the hammer (22) for continuous burst fire actuatable by the sear lever (26); a manual fire mode selector (34) connected to a rotating shaft (35) having a cam means (36) interacting with said opposing lever of the hammer for single shot fire (28) and with said opposing lever of the hammer for burst fire (29); an extractable magazine (8) for loading cartridge ammunition in a cartridge chamber of the barrel (4); a firing pin (37) for the ammunition actuatable by the hammer (22) and sliding in a direction parallel to the longitudinal axis of the barrel (4) in a seat provided in the bolt (6); the hammer (22) being configured and disposed so as to interact with the bolt in such a way as to absorb a significant fraction of the recoil kinetic energy of the bolt (6) for the attainment of the cocked position.

IPC Classes  ?

• F41A 9/55 - Fixed guiding means, mounted on, or near, the cartridge chamber
• F41A 9/70 - Arrangements thereon for discharging, e.g. cartridge followers or discharge throats
• F41A 17/72 - Firing-pin safeties, i.e. means for preventing movement of slidably-mounted strikers trigger-operated, i.e. the movement of the trigger bringing a firing-pin safety into inoperative position during the firing
• F41A 19/12 - Sears; Sear mountings
• F41A 19/14 - Hammers, i.e. pivotably-mounted striker elements; Hammer mountings
• F41A 19/33 - Arrangements for the selection of automatic or semi-automatic fire
• F41A 21/34 - Flash dampers
• F41C 23/04 - Folding or telescopic stocks or stock parts
• F41G 1/02 - Foresights
• F41A 3/54 - Bolt locks of the unlocked type, i.e. being inertia operated
• F41A 5/02 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock recoil-operated
• F41A 11/00 - Assembly or disassembly features; Modular concepts; Articulated or collapsible guns
• F41A 15/14 - Cartridge extractors, i.e. devices for pulling cartridges or cartridge cases at least partially out of the cartridge chamber; Cartridge ejectors, i.e. devices for throwing the extracted cartridges or cartridge cases free of the gun for bolt-action guns the ejector being mounted on, or within, the bolt
• F41A 19/27 - Mechanical firing mechanisms having only slidably-mounted striker elements, i.e. percussion or firing pins the percussion or firing pin being movable relative to the breech-block
• F41A 9/69 - Box magazines having a cartridge follower characterised by multiple-row or zigzag arrangement of cartridges
• F41A 5/08 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock recoil-operated having an accelerator lever acting on the breech-block or bolt during the opening movement
• F41A 5/10 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock recoil-operated having a movable inertia weight
