Definitions

  • the present invention relates to an individual shoulder weapon comprising a reversing brake. Capable of assuming multiple roles, it is able to increase the autonomy of the infantry, filling a gap in its equipment.
  • the design allows for a simple weapon that is safe to operate and easy to service. Its effectiveness provides significant fire support to the infantryman.
  • This very handy weapon because of its small size, its lightness and the good position of its center of gravity, is able to launch in tight shot at high initial speeds and with precision explosive projectiles of different types.
  • the unusual performance of this weapon can be compared to a real pocket cannon.
  • the low operating pressures ensure precious firing discretion for the user who can remain fused in infantry units during engagements.
  • the relative lightness of the ammunition in comparison with its caliber and the initial speed of the shell, allows the servant to have the many shots he is able to transport.
  • the characteristics of the weapon allow it to missions very diverse from each other. Its rifled barrel allows it to precisely reach punctual targets at unusual ranges in the firing range, being explosive shells for the infantry.
  • the weapon can be used during the progression of the infantry to execute embrasure shots intended to destroy machine-gun nests, shots to neutralize anti-tank weapons even protected by shields which were posted by the enemy in folds of ground & i i n, or, while the infantry is waiting on its positions, instant fire against enemy helicopters flying at low altitude, as well as attacks on vehicles carrying enemy, as pa the example of ATVs. Against these targets, the shooting of conventional rifles has no effect.
  • the weapon has the faculty to intervene without delay. This speed of implementation, like the reloading facilities and the great maneuverability, contribute to obtaining a good yield. This type of weapon, which was intended to be distributed to the infantry at the rate of a few copies per company, strengthens its firepower and its means of action without reducing its mobility.
  • the reversible brake shoulder gun comprises a frame, a barrel tube integral with a block having a cartridge chamber sliding in the frame and a recoil brake capable of partially absorbing the recoil energy of the tube -canon and the aforementioned block and cause the resetting of the barrel tube and the block.
  • the cartridge chamber is open towards the rear so that it is the cartridge case which alone ensures the closure of the cartridge chamber without requiring a cylinder head.
  • the sleeve is held in position by a mechanism for locking the ammunition which is mounted on the aforementioned block secured to the barrel-tube. In this way, the locking mechanism can be actuated during the movement of the barrel-tube and of the aforementioned block, by contact with means integral with the frame.
  • the ammunition locking mechanism preferably comprises at least one locking pawl pivoted on the aforementioned block and resiliently held normally in the locked position.
  • This original device replacing the cylinder head is preferably used in combination with a socket whose base thickness is reinforced so as to resist the thrust forces in the absence of any cylinder head. Since the weapon operates under low pressures, this reinforcement of the base of the casing is not very substantial and does not weigh it down much.
  • each of the locking pawls is preferably obtained by means of a first cam integral with each locking pawl and capable of cooperating, during the recoil stroke and during the resetting of the barrel tube and of the aforementioned block with a second cam secured to a flap pivotally mounted on the frame and subjected to an elastic return tending to move it in the direction of the aforementioned block.
  • the first and second cams preferably have a parallelogram shape, two faces of which are inclined so as to define wedge-shaped ends. These Extremists - moth-eaten facilitate pivoting each flap at the back and the pivoting of each locking pawl when handing in battery.
  • the shape and arrangement of the cams can be different so that the pivoting of each locking pawl causing the release of the cartridge case takes place on the contrary during the recoil movement.
  • the percussion mechanism is advantageously mounted on the aforementioned block secured to the barrel tube and it therefore separates from the trigger mechanism carried by the frame during the retraction of the barrel tube and the aforementioned block.
  • the hammer of the percussion mechanism is preferably mounted on the aforementioned block so as to come into contact, during the recoil stroke, with a stop secured to the frame which thus causes its rearming.
  • a movable stop controlled by the trigger mechanism is in contact with an oscillating pawl of the percussion mechanism which locks the dog in the armed position.
  • An elastically mounted ejector device for example subjected to the action of a spring, is further provided for ejecting the sleeve.
  • the device without breech of the shoulder gun of the invention which was designed to block the socket, allows the latter to benefit from an automatic ejection while having the merit of allowing further simplification of different mechanical organs. and to provide remarkable ease and speed of loading the ammunition.
  • the shoulder cannon with recoil brake according to the invention constitutes an individual one-shot weapon provided with an automatic ejector of the casing but with manual loading.
  • the type of ammunition used is sealed. Its projectile is of a significant caliber compared to the lightness of the weapon and the relatively high initial speed.
  • the present invention therefore makes it possible to produce a handy, robust individual weapon, of simple manufacture, of easy use and which does not present any particular technical difficulty.
  • the firearm shown comprises a tubular frame 1, open at its two ends, having at its front end a muzzle brake 2.
  • This muzzle brake 2 is either machined in the frame, or attached to it.
  • this frame 1 On the lower part of this frame 1 are fixed a handle 3, a shoulder pad 4 and a handle 5 enclosing a part of the detent mechanism and incidentally a folding grip handle 71.
  • the upper part of this frame 1 carries the fixed assembly 6 of a recoil brake, the movable part 7 of which is rigidly fixed to a block 8 enclosing the cartridge chamber screwed onto the rear end of a rifled barrel tube 9 slidably mounted inside the tubular frame 1.
  • the fixed assembly 6 of the recoil brake is fitted into two collars 69 of the frame 1 of the weapon.
  • a front cap 6a, and a rear socket 6b, both screwed onto the body 6 of the brake make the latter integral with the frame 1.
  • the recoil brake is removably mounted on the frame.
  • the barrel tube 9 is entirely housed in the frame 1 which effectively guarantees it against impact and which simultaneously constitutes thermal protection for the user.
  • the block 8 includes a rear extension 10 containing the percussion mechanism which moves with the barrel tube during the retreat after the start of the shot.
  • the handle 5 has on its rear face a security keeper 12 pivoted at 13 on the frame 1 and provided with a spout 14 cooperating with a part 15 of the expansion mechanism.
  • the front edge of the handle supports a trigger 16 pivoted on the handle at 17 and acting on an arm of a V-shaped lever 18 articulated by its center 19 on the frame.
  • the other arm of this lever 18 acts on a transmission rod . 20 bearing the part 15.
  • a manual locking consisting of a semicircular milled axis 21 pivoted in the housing of the handle and actuated by a safety lever 22.
  • this safety is locked, as illustrated in FIG. 4, any rotation of the lever 18 is prohibited.
  • the safety device 21 must be removed and the keeper 12 must also be pressed, this which causes the spout 14 which forms part thereof to be erased, and thus frees the part 15 integral with the transmission rod.
  • the handle 5, trigger 16, the lever 18, 'as well as the keeper 12 constitute an assembly removably mounted and retained on the frame 1 by means of two semicircular milled axes 23, the heads of which have slots screws accessible from outside the frame 1.
  • the shoulder plate 4 is also removably fixed using two semi-circular milled axes with slotted heads 24, 25 on the frame 1.
  • the transmission rod 20 slides in bearings 26, 27 integral with the frame 1 and its rear end, emerging from the frame 1 is constituted by a stop 28.
  • This rod 20 and this stop 28 are subjected to an elastic return action, here a spring 29 stretched between the stop 28 and the frame 1, intended to hold this rod 20 against the lever 18.
  • This stop comprises a transverse bore 28a passing through.
  • a damper 11, fixed on the frame 1, serves as support and protection, when the weapon is placed vertically on the ground.
  • the percussion mechanism comprises an oscillating pawl 34 pivoted on the extension 10 of the block 8 and subjected to the action a return spring 35.
  • the pawl 34 In the armed position, illustrated in FIG. 5, the pawl 34 is held in abutment against a pin 36 secured to the extension 10 and its end 37, having a beak, is engaged under the end 38 of the dog 39, pivoted on the extension 10 at 40, and the maintains in this armed position against the action of at least one spring 41.
  • the percussion head 39a of the dog 39 comes, by pivoting under the action of the spring 41, when its end 38 is released from the pawl 37, strike directly the primer 42 of a munition 43 introduced into the cartridge chamber 65, the rear end of larger diameter receives the rear edge of a socket 43a of an ammunition.
  • An ejector 50 subjected to the action of an ejection spring 51 comprises an ejection finger 52 housed in a countersink on the rear face of the block 8 which cooperates with part of the periphery of the sleeve 43a.
  • This ejector 50 is provided with a manual ejection ring 53.
  • the stroke of the ejector 50 is limited by a stop 60 fixed in the block 8 and the end of which is engaged in a longitudinal groove 61 of the ejector 50 (fig. 9).
  • the ammunition housed in the cartridge chamber of block 8 is normally maintained in the start position of the blow by two locking pawls 55 pivoted on block 8, the rear part of which has nozzles 56 coming into contact with the rear edge of the casing 43a.
  • Each locking pawl 55 is articulated on two sockets 54 driven into the block 8 and is subjected to the action of a spring plunger 57 tending to keep it in the locked position.
  • the upper front end 58 of the locking pawls 55 constitutes a manual unlocking member.
  • Two stops 67 limit the travel of the locking pawls 55 before loading the ammunition.
  • the weapon is equipped with an automatic opening device of the locking pawls 55, which opening takes place during the return in battery of the barrel after the departure of the shot.
  • This automatic opening device comprises a cam 59, integral with the lower arm of each locking pawl 55, having the shape of a parallelogram.
