Definitions
- the present invention relates to the field of firearms, in particular so-called “reduced lethality” launchers, and in particular to that of suitable ammunition and magazines, suitable for this type of launcher.
- the disclosure relates more specifically to a simplification of weapons compatible with low-power ammunition, in order to avoid as many moving parts as possible.
- a typical ammunition consists of a casing housing a projectile (such as a bullet) and a pyrotechnic charge, as well as a primer for igniting the thruster.
- the propellant located behind the bullet, is ignited, creating a combustion reaction, the gases generated from which allow the bullet to be thrown out of the barrel of the weapon.
- the weapon comprises a barrel in which chambers are hollowed out to contain the individual ammunition.
- the chambers are brought in turn by rotation in front of an independent barrel, thus making it possible to fire several shots successively.
- the mechanical operation of the revolver induces a certain number of movements of moving parts. Indeed, when you press the trigger, a lever pushes the hammer back, which compresses a spring located in the stock. At the same time, another lever pushes a notch at the rear of the barrel which allows it to rotate a fraction of a turn so as to place the next chamber facing the barrel and which, at the end of the movement, engages the locking of the barrel ensuring precise alignment with the barrel. Then, the trigger at the end of the stroke releases the hammer, the spring relaxes and pushes the hammer forward until the striker comes to meet the primer of the ammunition.
- the revolver therefore has the advantage of being a handgun with a magazine (barrel in this case) which can include several ammunition to fire several shots before having to reload.
- the classic revolver requires the use of several moving parts, operated entirely by the shooter's finger on the trigger. The sequence of movements of the various moving parts can be uncomfortable and represent a potentially annoying delay in firing.
- the present invention aims to overcome the drawbacks of the state of the art. It aims in particular to provide a weapon comprising the fewest moving parts, leading to an essentially electrical operation.
- One of the objectives of the present invention is therefore to simplify the design of the weapon as much as possible, in order also to simplify its manufacture and its maintenance.
- Another objective is to have a magazine which acts as a barrel, the magazine having in fact the function of a barrel, making it possible to have a more compact weapon.
- the magazine can also offer the possibility of firing several shots in succession without having to reload the weapon.
- the present invention also makes it possible to avoid having a combustion chamber in the launcher, the latter forming part of the casing, which allows the charger to be used with any type of device making it possible to enable primer. More specifically, this can be achieved by a launcher having a handgun design, but also a launcher with a simple straight shaft, similar to a flashlight shaft for example.
- the present invention also aims to provide a launcher with a removable magazine, which can be separated from the gripping part of the launcher.
- the ammunition can therefore be loaded beforehand in the magazine, before placing it on the gripping part of the launcher.
- Another objective is to allow manual locking of the ammunition in the barrel, making it possible to avoid having an insertion mechanism in the chamber.
- the invention is also particularly suitable for so-called reduced-lethality launchers. Summary of the invention
- the present invention discloses an ammunition, intended to cooperate with a barrel comprising first fixing means, the ammunition comprising a socket housing a projectile as well as an electrically primed primer, said socket comprising second fixing means capable of locking, in use, said ammunition in said barrel on the first fixing means.
- the invention comprises at least one or a suitable combination of the following characteristics: the electric ignition primer comprises a resistive bridge having a low resistance before its use and high after its use; the ammunition comprises a pyrotechnic charge producing, in use, a kinetic energy of the projectile relative to the impact surface of less than 100 Joules/cm 2 , preferably less than 50 J/cm 2 , typically of the order of 30 /cm 2 ; - the ammunition comprises a pyrotechnic charge producing a kinetic energy of projection relative to the impact surface of at least 7 J/cm 2 preferably at least 15 J/cm 2 .
- a second aspect of the invention relates to a barrel intended to cooperate with the electrically primed ammunition, comprising first fixing means allowing, in use, the locking of the ammunition inside the barrel by cooperation of the first means fixing and second fixing means.
- the locking of the ammunition in the barrel is preferably of the bayonet connection type.
- the barrel is preloaded with the ammunition.
- the locking of the ammunition in the barrel is preferably of the bayonet connection type.
- the first barrel fixing means are of the female type and the second sleeve fixing means are of the male type.
- the ammunition case protrudes from the barrel and is only partially lined by the barrel.
- a third aspect of the invention relates to a loader assembly comprising a plurality of barrels according to the invention, each barrel allowing the loading of an ammunition, the ammunition being lockable in the barrel using the first fixing means and second fixing means.
- the charger assembly comprises five barrels allowing the loading and unloading of five rounds of ammunition.
- a fourth aspect of the invention relates to a launcher comprising a removable magazine assembly that can be separated from the weapon.
- the launcher comprises a gripping part with orifices making it possible to accommodate, in use, the casing protruding from the magazine when the magazine is inserted on the gripping part.
- the sleeve part being located in one of the orifices when the charger is inserted on the gripping part is not held by this orifice, a clearance of between 0.3 and 5 mm being provided between the sleeve and the orifice, preferably between 0.8 and 3 mm, particularly preferably 1 mm.
- the launcher of the invention is a reduced lethality launcher.
- Figure 1 shows a three-dimensional view of an example of a launcher according to the present invention comprising the charger.
- Figure 2 shows a three-dimensional view of an example of a launcher according to the present invention with the charger disconnected from the launcher.
- Figure 3 shows a three-dimensional view of an example of a charger according to the invention, comprising five guns.
- Figure 4 shows a rear view of the charger of Figure 3, the charger being empty.
- Figure 5 shows a three-dimensional view of an example of ammunition according to the present invention.
- Figure 6 shows another three-dimensional view of the ammunition of Figure 5.
- Figure 7 shows a three-dimensional view of the charger of the figures
- Figure 8 shows a sectional view of an example of a launcher according to the present invention.
- socket 6 prehensible part of the launcher
- the present invention discloses a launcher 1 whose number of so-called “moving” parts has been considerably reduced.
- the launcher of the invention is shown generally in Figures 1 and 2, with a handgun appearance. However, its design can be totally different as explained below in more detail.
- weapon with reduced lethality we mean launchers with reduced probabilities of sustaining serious injuries.
- This reduced lethality can be obtained by the use of specific projectiles with low penetration (plastic projectile, rubber, breakable envelope comprising shot that disintegrates on impact, etc.) and/or density with reduced kinetic energy (ie the kinetic energy relative to the impact surface is less than 100 joules/cm 2 , preferably less than 50 joules/cm 2 , typically of the order of 30 joules/cm 2 ).
- projectiles can nevertheless be incapacitating, causing pain and/or a recoil effect sufficient to dissuade an attacker from continuing his action. They also allow in the case of certain projectiles to “mark” the target by means of easily identifiable dyes.
- the launcher 1 comprises a charger 2.
- This charger 2 is removable, and can therefore be detached from a gripping part 6 of the launcher
- the charger 2 has the specificity of also having the gun function. Indeed, as illustrated in Figures 3 and 4, the charger 2 comprises cylindrical holes 3 acting as guns. The ammunition 4 is therefore loaded beforehand into the various guns 3, before placing the charger assembly 2 on the launcher 1.
- These guns can be simple bores in the magazine, or comprise an internal sleeve acting as a barrel, for example in the case of a plastic magazine comprising a metal sleeve.
- the charger can also be molded in one piece.
- the charger 2 is fixed on the gripping part 6 of the launcher 1, namely the "active" part being capable of injecting the priming energy (electric current) to the ammunition 4 present in the barrel 3
- This gripping part 6 can have very different designs. It is represented here in the form of a handgun with a butt, a trigger tail 12 and all the firing trigger device in order to transmit the priming energy at the appropriate time. However, it can have a different design, with a straight handle like that of a flashlight. Indeed, in the case of the present invention, the launcher 1 must no longer include a combustion chamber 9 because the latter is part of the casing 5 and ammunition 4 assembly in itself. This aspect allows great freedom in terms of the type of launcher 1. In fact, the gripping part 6 must comprise only the firing trigger device making it possible to transmit the priming energy at the appropriate time.
- the figures represent a charger 2 with five barrels 3, but these could be of different numbers. It is also possible to have a magazine 2 with a single barrel 3. Having a removable magazine 2 makes it possible to interchange the type of magazine 2 (with the advantage of having an ammunition caliber that can vary from one charger to another, the electrical contacts on the charger 2 being located in the same places in order to be compatible with the gripping part 6). Each barrel 3 can be loaded and unloaded multiple times.
- the charger assembly 2 acts as a barrel 3, the launcher is more compact, namely shorter since the ammunition 4 is already inserted in the barrel 3.
- the weapon of the present invention does not include both a barrel and a magazine, but indeed a magazine acting as a barrel, the barrel 3 thus being completely integrated into the removable magazine 2.
- barrels 3 include locking elements 11.
- the present invention also relates to ammunition 4, having the specificity of having several functions. Indeed, each ammunition 4 is intended to carry the projectile 8, but also to lock it in the barrel 3. These ammunition also have the particularity of comprising an electric primer as described for example in US patent document 10,415,944. As illustrated in Figures 5 and 6, the ammunition 4 of the invention comprises a case 5 housing a projectile 8 as well as a primer 7 comprising a charge primary, and possibly a secondary charge, making it possible to project the projectile 8 out of the barrel 3 of the launcher 1 during firing.
- the ammunition 1 also comprises a combustion chamber 9 being included inside the casing 5, having the particularity that, when the ammunition 4 is inserted into the barrel 3, the casing 5 and in particular the part of the casing comprising the combustion chamber 9 is only partially lined by the barrel 3.
- the sleeve 5 protrudes from the barrel 3 and therefore from the magazine 2.
- Orifices 13 are provided in the gripping part 6 of the launcher 1 (see Figure 2) in order to accommodate the casing parts 5 projecting from the barrel 3 when the magazine 2 is inserted on the gripping part 6. However, the casing parts 5 being located in the orifices 13 when the magazine 2 is inserted on the gripping part 6 are not held by these orifices 13.
- the sleeve 5 comprises, on its outer surface, fastening means
- each barrel 3 comprises first means of fixings 11 allowing to cooperate with second fixing means 10 included on the sleeve 5 of the ammunition 4.
- the fixing of the ammunition 4 in the barrel 3 is preferably a bayonet type connection, namely a connection made by a "push-turn" movement, via lugs 10 penetrating into an L-shaped slot/recess 11. It is this type of fixing means which is shown in the figures, for which the first fixing means 11 are therefore female-type fastening means, and the second fastening means 10 are male-type fastening means.
- any suitable type of fixing can be used.
- screwing may be possible.
- a groove can be made in the ammunition 4, and a spring in the barrel 3, so that the ammunition 4 is clipped using the groove in the barrel 3 by pushing the spring.
- the ammunition of the present invention is therefore not smooth due to the presence of the fixing elements 10.
- the sleeve is preferably made of plastic material, with the polymer projectile.
- the locking of the ammunition 4 in each barrel 3 is done manually. In this way, the extraction of casings 5 after firing is facilitated.
- the ammunition 4 lockable in the barrel 3 makes it possible to simplify the mechanism of the semi-automatic launcher, because there is no need for an insertion mechanism in the barrel 3. In fact, since the magazine 2 acts as the barrel 3, the ammunition 4 is locked directly manually in the barrel 3.
- the socket 5 of the ammunition 4 has a geometry such that it overflows from the barrel 3 when it is inserted and locked therein. In this way, gripping of the ammunition 4 by the user is facilitated.
- the charger 2 with several barrels 3 has the advantage of semi-automatic launchers. Moreover, as the magazine 2 is removable, the user can have some in stock in his pocket, with the ammunition 3 already placed in the magazine 2. The principle of locking the ammunition 4 makes it possible to prepare the loading in advance without risk of losing ammo 4.
- 1 of the present invention preferably has a 100% electrical use, with the exception of the firing trigger mechanism.
- each barrel 3 comprising the ammunition 4 will be used in turn during firing.
- the launcher comprises a device configured to execute the steps of a securing method:
- the electrical element allowing the ammunition to be primed has low heat resistance so that ignition of the primary charge destroys it.
- the detection of an infinite resistance on the priming circuit makes it possible to determine that the loaded ammunition has already been used and needs to be replaced. This characteristic is particularly useful in the case of multiple ammunition placed in a circuit provided for sequential ignition of different cartridges loaded simultaneously.
