FR2768805A1 - HANDGUN FOR NEUTRALIZATION PROJECTILES - Google Patents

Abstract

The present invention relates to close defense weapons intended to immobilize an aggressor. The present invention relates more precisely to a handgun provided with an ejection barrel (1) intended to expel neutralization projectiles, the muzzle of said barrel being set back from a protuberance (2) integral with the weapon. The protuberance (2) makes it possible to avoid touching butt firing by leaving a minimum firing distance between the muzzle (1) and a target bearing against the protuberance (2). Neutralization projectiles can be either deployable or deformable. The weapon, thus designed, can effectively neutralize an attacker without causing him irremediable injury.

Description

The technical field of the invention is that of defense weapons

  close quarters intended to immobilize an attacker. The weapons currently available on the market consist of neutralizing gas diffusers, electric shock weapons and weapons intended to launch non-lethal projectiles such as rubber bullets for example. In this last category of weapon capable of expelling deformable projectiles, no means today makes it possible to prevent the shooting with touching point, ie the shooting for which the point

  of the barrel is in contact with the aggressor.

  In this extreme situation which can be encountered during a melee, the projectile comes to impact the aggressor while being always compacted in the barrel and therefore without being able to deform. The bodily effects then generated by this type of impact, associated with the secondary effects of burns linked to the expansion of hot gases at the outlet of the barrel, can be

  extremely dangerous or even lethal.

  A close-range defense weapon capable of launching neutralization projectiles, and which is intended for the general public, must make it possible to neutralize an attacker without causing him irreparable injuries, for the normal use of the weapon in any situation. The expression "normal use" means that the weapon is aimed at the aggressor in a position for which the barrel aims at the part of the body to

achieve.

  The weapon according to the invention meets this need.

  The present invention relates to a handgun intended for firing neutralization projectiles and comprising in particular a barrel, characterized in that the mouth of the ejection barrel is located behind a protuberance secured to the weapon. Said protuberance thus makes it possible to avoid firing at touching point since, in normal use, the target can only come to bear against the protuberance and not against the mouth of said cannon. This protuberance concept is of interest both to revolver-type stock pistols and to new handguns with a handle fitted with a pusher

to fire.

  Advantageously, the protuberance provides a distance of at least 30 mm between the muzzle of the barrel and

  a target coming to bear against the protuberance.

  The protuberance which can, in an extreme situation, serve as a stop for the target, must not be sharp or

blunt.

  Advantageously, the protuberance is constituted by a reamed cylinder similar to a revolver barrel. Indeed, the barrel of ejection of the projectiles being bored in the lower part of the carcass of the weapon, it remains invisible to the eyes of the aggressor and the dissuasive aspect of the weapon will be restored by the barrel

  factitious materializing the protuberance.

  Preferably, several cartridges each containing a neutralization projectile can be loaded into the weapon. The weapon can then

  be used as a repeating weapon.

  According to a preferred embodiment of the invention, the

  cartridges are housed in a monolithic ammunition.

  Preferably, the monolithic ammunition is a rotary magazine. Advantageously, the rotary magazine is made of plastic so that any attempt to extract the cartridges would systematically result in total or partial damage.

of said rotary magazine.

  According to another preferred embodiment of the invention, the cartridges are embedded in the monolithic ammunition so that they cannot be extracted from

  said ammunition with usual commercial tools.

  Preferably, the projectiles have a diameter greater than or equal to 11.6 mm. According to a preferred embodiment of the invention, the projectiles are deformable on impact

  to avoid any deep injury.

  According to another characteristic of the invention, the projectiles are deployable just after leaving the

gun and before impact on the target.

  The length of the protuberance must be such as to prevent a deformable projectile from impacting the target while it is still compacted in the barrel or a deployable projectile from impacting the target.

  target before it has had time to deploy.

  According to a first embodiment of the invention, the weapon has the form of a revolver and comprises an apparent upper barrel constituting the protuberance, and a barrel for ejecting the neutralization projectiles bored in the carcass of the weapon and placed under the upper barrel, parallel to it and back from it. Advantageously, the barrel constituting the

protuberance is blind.

  According to a second embodiment of the invention, the handgun comprises a handle which is provided in its upper part with a member for triggering the firing, and the lower part of which comprises

the ejection barrel.

  Advantageously, the member for triggering the firing is a pusher which slides in translation and moves outward a linear magazine engaged in an opening located in the lower part of the handle. The weapon according to the invention has the advantage of being able to effectively neutralize an aggressor without injuring it irreversibly, by avoiding, by

  normal use, shooting at close range.

  Unlike other close defense methods in force on the market such as gas diffusers, this type of weapon can be used several meters from the aggressor to avoid hand-to-hand combat. In addition, it cannot be transformed into an offensive weapon with the use of usual commercial tools. These two advantages give the weapon a non-dangerous aspect perfectly adapted to the demand of the great

public.

  Finally, the great maneuverability of the weapon due to its lightness, associated with a very simple implementation, allows rapid intervention, therefore effective, against the aggressor.

  A detailed description of the mode is given below

  preferred embodiment of the two variants of the invention

  mentioned above, with reference to Figures 1 and 2.

  FIG. 1 represents a view in longitudinal section comprising an auxiliary partial section of a handgun according to the invention in the position of

  rest and including a stick and a trigger.

  Figure 2 is a partial sectional view of a handgun according to the invention comprising a handle and a pusher, in the last position preceding

the shot.

  Referring to FIG. 1 relating to a preferred embodiment of the first variant, the handgun comprises a barrel 1 for ejecting the neutralizing projectiles and a blind upper barrel 2, a rotary magazine 3 coming to be fixed on tear. The ejection barrel 1 is bored in the carcass 4 of the weapon and is located under the upper barrel 2, parallel to it and back from it. The upper barrel 2 constitutes a passive protuberance for the weapon. The rotary magazine 3 is a cylindrical monolithic piece of plastic material having a circular front face and a circular rear face. The magazine 3 presents itself externally as a barrel and has six cylindrical chambers whose axes are parallel to its axis of rotation 6. Said chambers 5 dig right through the monolithic part and are arranged so that their circular sections are regularly spaced around of a circle. In each chamber 5 is securely embedded by overmolding a cartridge having a neutralization projectile so that these cartridges cannot be dislodged with conventional commercial tools without damaging the plastic magazine 3. Between the upper barrel 2 and the ejection barrel 1 is hollowed out, in the carcass 4 of the weapon, a parallel cylindrical channel 7 which comprises the cylindrical part 8 to 12 and a spring 13 ensuring the maintenance

  and centering the rotary magazine 3.

  The circular front face of the rotary magazine 3 has a conical recess in its center. When the weapon is devoid of its magazine 3, the conical end 12 of the cylindrical piece housed in the channel located between the two barrels 1, 2 projects into the space of the carcass 4 reserved for the location of said magazine 3. To insert magazine 3 into the weapon,

  the user must remove from the space reserved for said store 3 the conical end 12 by translating by the head 11 the cylindrical part in its channel 7.

  Once the magazine 3 is in place, the user releases the head 11, and by the return effect due to the spring 13 which relaxes, the conical end 12 is fitted into the conical recess of the circular front face of the magazine 3. The rotary magazine 3 has six rounded recesses arranged on its external cylindrical surface. One of these recesses into which the lobe of the part 14 penetrates is shown in partial section offset in FIG. 1. These recesses are regularly spaced and are placed in the middle of two successive chambers. At rest, the rounded part of a part 14 is inserted into one of the recesses so that the magazine 3 can no longer rotate around its axis of rotation 6. In FIG. 1, the part 14 partially inserted in one of the recesses belongs to a plane located behind the cutting plane. A striker 15 is positioned opposite the chamber which will be in continuity with the ejection barrel 1. A trigger 16 will make it possible to trigger the firing by actuating a weight 17 for striking the striker 15. Finally, a rotation lever 18 will rotate the store 3 around its axis 6 during a

pressure on the trigger 16.

  The operation of the weapon follows the steps

following.

  The user engages the rotary plastic magazine 3 provided with cartridges in the space of the carcass 4 of the weapon reserved for this purpose. To do this, it proceeds as described above. Once the magazine 3 has been inserted into the weapon, the part 14 is partially housed in one of the six peripheral recesses of the magazine 3 so as to block it around its axis of rotation 6. This position of the magazine 3 corresponds to

  aligning a chamber with the ejection barrel 1.

  Pressing the trigger 16 will generate a triple action: first, the part 14 blocking the magazine 3 will pivot to release said magazine 3 about its axis of rotation 6. Then the rotation lever 18 is set in motion and goes cause a rotation of a sixth of a turn of the magazine 3 around its axis 6 so as to bring the next chamber in front of the ejection barrel 1. Finally, the striking weight 17 of the striker 15 is moved until causing the percussion of the cartridge. Once fired, the user releases the trigger 16 to its rest position. The weapon is again ready for a new shot. When the six cartridges have been used, the user removes the plastic magazine 3 and discards it. It can replace it with another store

full.

  Referring to FIG. 2 relating to a preferred embodiment of the second variant, the handgun comprises a handle 20 including a linear magazine for cartridges and the constituent parts of the triggering mechanism for shooting, an elongated monobloc part 21 , a member 22 for triggering the firing and a

  ejection gun 23 of the projectiles of neutralization.

  The handle 20 is constituted by an elongated body slightly curved to facilitate a good grip of the weapon with the hand, and has an upper part including the pusher 22 and a lower part

including the ejection barrel 23.

  Said upper part is connected to said lower part by means of an elongated monobloc piece 21 starting at the end of the upper part located beyond the pusher 22 and ending

  on the external lateral surface 24 of the barrel 23.

  The one-piece elongated piece 21 has a straight segment 25 perpendicular to the axis of the barrel 23 and located in front of the mouth of said barrel 23 relative to the handle 20. The one-piece elongated piece 21 constitutes by this segment 25 a protuberance avoiding firing touching toe. The pusher 22 is an elongated part having in particular a slightly curved front face 26 to prevent the finger which will actuate it from sliding, and a rounded rear recess 27. A pressure on the pusher 22 causes said pusher 22 to translate in a parallel direction to the axis of the barrel 23. The thin mixed lines in FIG. 2

  materialize the position of the pusher 22 at rest.

  The rounded rear recess 27 of the pusher 22 receives the rounded part of an elongated rotary part 29 bearing against a part 30 secured to the striking weight 31. The translation of the pusher 22 will induce a linear displacement of the rounded part of the elongated part 29, said part 29 performing at the same time a rotation about its axis. This rotation will in turn induce the rotation of the counterweight 31 by means of the part 30 which is integral with it. When the pusher 22 continues to be depressed, the rotating elongate part 29 ends up losing contact with the counterweight 31 which, immediately, pivots around its axis in the opposite direction, undergoing a sudden acceleration due to the pushing of a part 32 moved by a spring 33 which relaxes. The striker 34 being integral with the counterweight 31 strikes the cartridge located in front of the barrel 23. The fine mixed lines in FIG. 2 materialize said striker 34 in the percussion position. The linear plastic magazine comprising the cartridges provided with their neutralization projectile is introduced into the weapon by an opening 28 located in the lower part of the handle 20. The magazine comes

in abutment against a spring.

  On each shot, by means of a lever (not shown), the end of which is housed in the groove, the magazine is translated towards the outside of the handle 20 by a length corresponding to the spacing between two cartridges of the store. After a number of shots, the plastic magazine emptied of its cartridges is expelled from the weapon. It is then discarded to be replaced by a

charger full.
