FIREARM COMPRISING A SKELETON FRAME DESIGNED TO ACCEPT A CARTRIDGE ACTING AS A GUN BARREL
Firearm comprising a trigger, a sear lever, a firing pin and a grip acting as a butt. The firearm has, as an extension of the grip (4), a skeleton frame (5) designed to accept, removably, a cartridge (6) that is able to act as a gun barrel and, conversely, the cartridge/gun barrel (6) and the skeleton frame (5) have complementary angular-indexing and locking arrangements of the 1/4-turn type.
The safety device for a firearm firing pin system comprises a firing pin (1) secured to a trigger release (2). Said device comprises a removable independent element (5) that can be engaged: - in an arrangement (6) of part of the weapon in order to deliberately block the firing pin (1) and the trigger release (2) in a position in which said firing pin (1) is either armed or not armed, removal of said element (5) allowing the firing pin (1) and the trigger release (2) to be released in order to fire a shot and/or in order to load the weapon; - in another arrangement (8) of part of the weapon in order to collaborate with the firing pin system (1), by means of complementary coupling means, in order to arm the firing pin (1).
F41A 3/72 - Operating handles or levers; Mounting thereof in breech-blocks or bolts
F41A 17/30 - Multiple safeties, i.e. safeties acting on at least one element of the firing mechanism and at least one other element of the gun, e.g. the moving barrel

F41A 17/64 - Firing-pin safeties, i.e. means for preventing movement of slidably-mounted strikers
A linear repeating firearm, with assisted ejection, comprising: means capable of recovering the energy resulting from the pressure exerted when firing a round of ammunition (7) with a view to moving a mobile assembly (4) against an elastic return member and comprising a stopper, a latch and a striker cooperating with a hammer (5) controlled by a trigger (6), locking means (11) at the rear of the mobile assembly (4), in the compressed position of the return spring (10), after each shot, a manually actuatable unlocking assembly (12) capable of acting on the locking means (11) to release the mobile assembly (4) and allow the assisted return of said assembly (4) with a view to reloading.
F41A 5/18 - Mechanisms or systems operated by propellant charge energy for automatically opening the lock gas-operated
F41A 17/32 - Multiple safeties, i.e. safeties acting on at least one element of the firing mechanism and at least one other element of the gun, e.g. the moving barrel the other element being the breech-block or bolt
F41A 3/26 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks semi-automatically or automatically operated, e.g. having a slidable bolt-carrier and a rotatable bolt
6.
LARGE-CALIBRE FIREARM ROUND FOR FIRING A PROJECTILE
The round comprises a case (1) of cylindrical overall shape, one end (1a) of which is open while the opposite end is closed and exhibits a coaxial chamber (1b) intended to accommodate a propulsive cartridge (2) containing wadding (3), the projectile (4) being housed in a cup (5) fitted from the open end (1a) of said case (1). According to the invention, the case (1) has at least one means (6) capable, firstly, of holding back the wadding (3) upon percussion of the cartridge (2) so that said wadding (3) does not come into contact with the bottom (5a) of the cup (5) so that it is subjected directly to the pressure of the gases, and secondly to keep the wadding (3) inside the case (1).
The device comprises a system of linkages (8) and (9) which are connected to the moving gear of a receiver and able to be moved linearly in a back and forth motion parallel to a barrel (4). According to the invention, the device comprises a connecting piece (6) fastened to the system of linkages (8) and (9) and mounted with the ability to move linearly, guided on a rod (7) mounted parallel to and underneath the barrel (4), said piece (6) being secured, through an aperture (5a) formed under a fixed forestock (5) to an operating member (10) that partially hugs the cross section of said forestock (5) and is mounted with the ability to move in order at the same time to move the system of linkages (8) and (9) and, therefore, the moving gear of the receiver, said forestock (5) remaining conventional and stationary and performing the function of protecting the system of linkages.
