  • the present invention relates to a long gun intended for firing ammunition with strong impulse.
  • the present invention proposes to provide a weapon using this technique of shock absorbing systems which produce a constant force during a given stroke, the length of which is a function of the pulse to be damped, these shock absorbing systems being used in combination with safety systems, and other damping systems, making it possible to launch relatively large caliber projectiles (for example up to at least 80 mm) using an individual long gun.
  • the subject of this invention is therefore a rechargeable, single-barrel weapon, making it possible to use a whole range of ammunition of varying masses, speeds and effects, generally operating with the same impulse, this weapon being designed so as to present a large recoil stroke, for example greater than 600 mm.
  • the shoulder safety plate is mounted on a shoulder plate provided in the stock and which is lined with an energy-absorbing material and / or means which also ensure its implementation. conform to the shooter's morphology.
  • the maneuvering part of the movable breech is connected to the shock absorber system, this connection being designed so as to lock or unlock the breech, by displacement of the barrel once the muzzle has returned to the battery.
  • a recuperative spring acting on the barrel to ensure automatic reloading of the weapon when the breech is released after returning to the battery, by the forward movement of the barrel resulting from the return energy from the muzzle.
  • the recoil damping system is preferably of the cylindrical friction type acting in the reverse direction and free in the opposite direction, this system can include a friction damping cylinder, ensuring braking, sliding on a guide rod , the backward movement being ensured by a helical spring bearing on the damping cylinder and on the stick, this spring being positioned on the guide rod.
  • this recoil damping system comprises a fixed cylinder mounted on a movable rod connected to the cylinder head, a return means, for example of the pneumatic type, ensuring the return towards the front of the rod driving the cylinder head.
  • the percussion mechanism is constituted by a floating striker with spring return located in the movable cylinder head, this striker being actuated by a hammer provided with a spring, this hammer being able to engage in a double exhaust system connected to the trigger, said hammer articulated on the cradle being locked in the armed position by a cam controlled by the shoulder safety plate.
  • the weapon is of the automatic loading type and it comprises a magazine provided with several ammunitions, this magazine being positioned at the rear of the weapon, at the location where occurs the recoil of the barrel-breech assembly, which assembly can retreat through an opening provided in the magazine, the supply of the firing chamber by a new cartridge occurring when the barrel is returned to the battery, after extraction and ejection of the empty case.
  • the weapon is provided with a sighting system which comprises a clear sight with projected reticle, a laser rangefinder, a goniometer, preferably with variation of magnetic flux and a computer comprising a memory in which the ballistic data of the ammunition is introduced, the firing line being started by action on said contactor.
  • the weapon uses ammunition each provided with a ballistic identification code, for example a bar code with optical reading, the information of which is transmitted to said computer during aiming operations.
  • a ballistic identification code for example a bar code with optical reading
  • the weapon object of the present invention essentially comprises a barrel 1 closed by a movable bolt 2 provided with locking pins 3, this movable bolt being controlled by an operating part 4 with rectilinear movement acting on a stud 5 moving on a helical ramp 6 to communicate a rotational movement limited to the movable breech 2, this movement being obtained by the displacement of the barrel.
  • the assembly formed by the barrel 1, the movable breech 2 and the operating part 4 can slide on a cradle 7 secured to the butt 8, pads such as 9 facilitating this sliding.
  • the weapon is provided with a recoil damping mechanism which in the embodiment illustrated in FIG. 1, is of the known type, cylindrical with friction.
  • a recoil damping mechanism which in the embodiment illustrated in FIG. 1, is of the known type, cylindrical with friction.
  • this damping mechanism essentially comprises a damping cylinder 10, ensuring braking, which can slide on a guide rod 11, a helical spring 12, mounted on the guide rod 11 and pressing on the damping cylinder 10 and on a ring fixed 13 secured to the butt 8 to ensure the return to the battery.
  • the operating part 4 of the movable breech 2 is connected to the rod 11 of the shock absorber (FIG. 1), the connection being made so that the actuation of the barrel causes the movable breech to be locked or unlocked.
  • This function can also be performed in the manner illustrated in FIG. 2 using a recuperator spring 16 acting on a latch 17, 17 ′ which can immobilize the barrel-breech assembly on the cradle 7 as will be described. below.
  • a magazine 18 containing a certain number of cartridge-filled ammunition (three in the 'exemplary embodiment shown), these munitions being held by a spring 20.
  • the barrel assembly 1, breech 2 can retreat through the magazine 18 as will be seen below -after during the description of the operation of the weapon.
  • an identification means can be provided defining the type of ammunition contained in the magazine, this identification means possibly consisting of a code preferably a bar code that can be read optically.
  • the butt 8 is preferably made of a composite material and it serves as a support for the cradle 7 as described above, and for the sighting system which will be described below with reference to FIG. 3; it contains in addition the safety and percussion mechanism shown in detail in FIG. 2 and described below.
  • This stock 8 comprises a shoulder plate 21 which is lined with a shock absorbing material and preferably with a material which is moreover susceptible to automatically adapt to the shooter's morphology.
  • This shoulder plate 21 further comprises a movable safety plate 22 which is designed so as to lock the percussion mechanism when at rest the weapon is not shouldered, the shooter having to firmly press the weapon on his shoulder, by pushing in the safety plate 22, to release the percussion mechanism as will now be described.
  • This percussion mechanism ( Figure 2) consists of a floating striker 23 provided with a spring 24 located in the movable cylinder head 2.
  • This striker is actuated by a hammer 25 articulated on the cradle 7 via a pin 26 and returned by a spring 27.
  • the end of the hammer is engaged with a dual exhaust system 28, 28 'provided with a return spring 29 and oscillating around an axis 30.
  • the dual exhaust system 28, 28 ' is connected to the trigger 31 of the weapon by means of a button cable 32.
  • the hammer 25 articulated on the cradle 7 is locked in the armed position using a cam 33 actuated by the movable safety plate 22.
  • the movable safety plate is connected to the trigger, by means of a cam and a cable, the connection being such that the trigger, devoid of pivot axis, uses this cam as pivot axis, so that this trigger is erased and inoperative in the rest position when the shooter does not support the weapon and that it is in the active position when the weapon is supported, the cam then serving as an axis pivot to trigger.
  • FIG. 3 shows by way of nonlimiting example a sighting system with which the weapon can be provided.
  • the aim of the weapon is therefore ensured here by a simplified firing line comprising a clear sight with projected reticle 34, a laser rangefinder 35 with goniometer, preferably with variation of magnetic flux and a computer 36 comprising a microprocessor, a clock and a memory into which ammunition ballistic data are entered.
  • the firing line is started by an actuator 37 provided on the front handle 14 of the weapon held by the shooter's left hand.
  • One can also provide a code reader 37 which ensures the optical reading of the code, for example a bar code, displayed on the cases of the cartridges 19, so as to produce the information relating to the corresponding ballistics of the ammunition and to transmit it to the computer 36.
  • the shooter exerts traction on the breech assembly, the operating part remaining fixed, which has the effect of rotating the movable breech and disengaging the locking pins 3.
  • the barrel can advance freely, by releasing the location of the magazine 18. This magazine is introduced into the weapon and a reverse maneuver on the barrel closes the breech after introduction of a cartridge into the chamber of the barrel 1 (this operating phase is illustrated by FIG. 1 ).
  • the shooter then presses the shoulder of the weapon against his shoulder.
  • the shoulder plate 21 then conforms to its morphology and by pushing the shoulder safety plate 22, the shooter unlocks the hammer 25 (or activates the trigger according to the variant described above) before actuating the striker 23.
  • This unlocking is achieved by the displacement of the cam 33 during the insertion of the safety plate 22 by the shooter's shoulder (see FIG. 2), and in the variant this unlocking is obtained by the cam on which the trigger is pressed, this cam itself serving as an axis of rotation.
  • the shooter aims at the target and once the aim is achieved, he presses the actuator 37 of the front handle 14 in order to control the firing sequence.
  • the aiming of the target makes it possible to measure the distance using the laser rangefinder 35 harmonized with the viewfinder 34, the girometer recording the angular displacements, the data thus introduced into the computer 36 defining the speed and the distance of the target.
  • the actuator 37 is produced so as to act on a safety bolt of the striker.
  • the code reader 37 introduces into the computer 36 the ballistic data of the ammunition and this computer displays the point to be aimed by movement of the reticle of the viewfinder controlled by the button 38. The shooter reposition the reticle on the target and he can then pull the trigger 31. The hammer 25 is released from the chin 28 of the double exhaust system and it then strikes the striker 23 which sets the ammunition fire.
  • the barrel-breech assembly At the end of the race, the barrel-breech assembly returns towards the front under the action of the recuperator system, the barrel, by inertia, starts again forward, thus controlling the opening of the breech by a traction which causes the rotation of the cylinder head thanks to the helical ramp 6, and its stall.
  • the barrel returns in battery to return the breech to the locked position, with new ammunition in place in the chamber ( Figure 1), the breech being immobilized by the friction damping system.
  • the hammer 25 remains attached to the chin 28 'of the double exhaust system.
  • the double exhaust system 28, 28 ′ swings around its axis 30 while retaining the hammer by its other end, or chuck 28, which makes it possible to fire during a new action on trigger, as explained above.
  • the invention provides a rechargeable multi-purpose multi-purpose weapon, multi-ammunition capable of firing projectiles with large impulse (of the order of 100 Ns), with a large recoil stroke.
  • This weapon is also modular thanks to its interchangeable elements: magazine, barrel-breech system, and cradle and stock assembly. Thus, a simple change of barrel allows the use of different caliber ammunition with the same weapon.
  • This weapon is further characterized by great job security since it can only operate after support by the shooter and the aiming operation completely carried out.
  • the weapon according to the present invention can fire ammunition with limited recoil energy of the type described for example in the patent application filed by the present owner on the same day as the present application and entitled: "ammunition for cannon, mortar and the like. limited recoil energy ".
  • It may also preferably include a shoulder plate produced in application of the provisions described and claimed in the patent application filed on the same day as the present application and entitled "energy absorption device and adaptation to the morphology”.
  • this weapon can be fitted with an improved scope as described in the patent application filed on the same day as the present application by the holder and entitled: "improvements made to riflescopes, in particular for individual weapons”.
