Abstract
Description
L'invention concerne un dispositif de tir comprenant une arme à feu et sa munition.The invention relates to a firing device comprising a firearm and its ammunition.
Plus particulièrement l'invention porte sur une arme à feu semi-automatique et sa munition destinée à lancer un projectile à létalité réduite, projectile devant être propulsé à basse pression pour ne pas se briser.More particularly, the invention relates to a semi-automatic firearm and its ammunition for launching a projectile reduced lethal projectile to be propelled at low pressure to not break.
Les systèmes de propulsion pyrotechnique nécessitant une combustion à haute pression pour fournir un cycle balistique régulier, ce projectile de par sa fragilité, ne peut être propulsé directement comme dans une munition de petit calibre classique.Pyrotechnic propulsion systems requiring high-pressure combustion to provide a regular ballistic cycle, this projectile by its fragility, can not be propelled directly as in a conventional small caliber ammunition.
Usuellement, une arme à feu comporte un canon avec une chambre, un mécanisme d'extraction, d'éjection et d'alimentation.Usually, a firearm includes a barrel with a chamber, an extraction, ejection and feeding mechanism.
La présente invention propose un dispositif de tir comprenant une arme à feu avec un canon sans chambre, et sans mécanisme d'extraction ni d'éjection, l'extraction n'étant pas nécessaire et l'éjection étant assurée par les munitions présentes dans le chargeur.The present invention provides a firing device comprising a firearm with a chamberless barrel, and without extraction or ejection mechanism, the extraction being unnecessary and the ejection being provided by the ammunition present in the barrel. charger.
Usuellement, dans une arme à feu semi-automatique, la munition est sortie du chargeur et est alimentée dans l'arme.Usually, in a semi-automatic firearm, the ammunition is removed from the magazine and is fed into the weapon.
Dans le cadre de la présente invention, la munition ne quitte pas le chargeur pendant la phase d'alimentation et il n'y a pas de cycle d'alimentation proprement dit.In the context of the present invention, the ammunition does not leave the charger during the supply phase and there is no power cycle itself.
A cette fin l'invention propose un dispositif de tir comprenant une arme à feu et sa munition, l'arme à feu comprenant une carcasse, un canon, un chargeur, un mécanisme de mise à feu et la munition comprenant une ou plusieurs cartouches chacune sous forme d'une douille avec un projectile et une charge propulsive, le dispositif étant caractérisé en ce que l'arme à feu comprend des moyens pour amener une cartouche dans le chargeur devant l'entrée du canon et en appui contre un élément d'appui de la carcasse qui comprend le mécanisme de mise à feu et que le canon est coulissant dans la carcasse entre au moins une position avancée pour la mise en place et l'éjection d'une cartouche et une position de tir reculée dans laquelle le canon vient en butée sous l'action d'un ressort de rappel contre la partie avant de la douille de la cartouche qui se trouve devant l'entrée du canon, et en ce que chaque cartouche est pourvue de moyens de propulsion pour, après avoir actionné le mécanisme de mise à feu, projeter la douille et le canon vers l'avant pour déplacer le canon vers sa position avancée, la douille de la munition étant dotée de protubérances extérieures permettant d'activer une partie du mécanisme de l'arme à feu.For this purpose, the invention provides a firing device comprising a firearm and its ammunition, the firearm comprising a carcass, a barrel, a magazine, a firing mechanism and the ammunition comprising one or more cartridges each. in the form of a socket with a projectile and a propellant charge, the device being characterized in that the firearm comprises means for bringing a cartridge into the magazine in front of the entry of the barrel and bearing against an element of carcass support that includes the firing mechanism and that the barrel is slidable in the carcass between at least one advanced position for the emplacement and ejection of a cartridge and a retracted firing position in which the barrel abuts under the action of a return spring against the front portion of the cartridge sleeve which is in front of the barrel entrance, and in that each cartridge is provided with propulsion means for, after having actuated l firing mechanism, projecting the bushing and barrel forward to move the barrel to its forward position, the ammunition socket being provided with external protuberances for activating part of the firearm mechanism .
Avec un dispositif de tir selon l'invention, la douille de la cartouche forme pour ainsi dire un prolongement du canon de l'arme à feu et remplit en sorte la fonction de la chambre de canon dans une arme classique ainsi qu'une partie du canon.With a firing device according to the invention, the sleeve of the cartridge forms, so to speak, an extension of the barrel of the firearm and thus fills the function of the barrel chamber in a conventional weapon as well as a part of the barrel.
De cette manière on évite que la cartouche doive être alimentée dans le canon et extraite du canon après le tir.In this way it is avoided that the cartridge must be fed into the barrel and extracted from the barrel after firing.
On n'a donc plus besoin de mécanisme d'alimentation et d'extraction comme dans le cas des armes connues.There is no longer a need for power and extraction mechanisms as in the case of known weapons.
La munition est réalisée de manière à supporter les pressions qui résultent de la mise à feu de la charge propulsive.The ammunition is made to withstand the pressures that result from the firing of the propellant charge.
L'invention porte également sur une arme à feu et sur la munition pouvant être utilisées dans un dispositif de tir selon l'invention.The invention also relates to a firearm and ammunition that can be used in a firing device according to the invention.

L'utilisation et le fonctionnement du dispositif de tir sont simples et sont illustrés comme suit au moyen des dessins 10 à 19.The use and operation of the firing device are simple and are illustrated as follows by means of drawings 10-19.
La figure 10 montre une arme à feu 16 comprenant quelques cartouches 1 dans le chargeur 20, dont une cartouche 1 est prête a être tirée et qui se trouve encastrée entre l'élément d'appui 22 et l'entrée 31 du canon 19, le piston 7 étant en appui contre cet élément 22 avec la charge propulsive en face du mécanisme de mise à feu 21.FIG. 10 shows a
Le canon 19 se trouve dans cette situation dans une position reculée de tir dans laquelle le canon 19 vient en butée contre la partie avant 15 de la douille 2 de la cartouche 1 sous l'action du ressort de rappel 27.The
Comme il est indiqué plus en détail dans la figure 12, l'ergot avant 13 fait monter le poussoir 41 qui fait basculer le levier 37 pour éloigner l'extrémité 39 du canon 19.As is shown in more detail in FIG. 12, the
La figure 13 montre que dans cette situation la partie avant de la douille 2 est emboîtée dans la bague 32 de l'entrée 31 du canon 19 et est centrée dans cette bague 32.FIG. 13 shows that in this situation the front part of the
Quand le mécanisme de mise à feu 21 est actionné par la détente 23 pour tirer, la charge propulsive 8 s'amorce et des gaz sous pression vont remplir la chambre haute pression 4.When the
De ce fait, le piston 7 étant en appui, la douille 2 est lancée vers l'avant et emporte le canon 19 dans son mouvement, comme représenté dans la figure 14.As a result, the
Les gaz à haute pression peuvent s'échapper à travers les trous d'évent 10 vers la chambre basse pression 3, pour propulser le projectile 6 via le canon 19 comme dans la figure 14.The high pressure gases can escape through the vent holes 10 to the
L'étanchéité entre le canon 19 et la douille 2 se réalise entre autres par le recouvrement entre le canon 19 et la partie avant 15 de la douille 2 et par le fait que cette partie avant 15 est réalisée en matière plastique qui est poussée contre le canon 19, l'inertie du canon 19 permettant de créer une pression de contact importante entra la partie avant 15 et le canon 19, créant l'étanchéité désirée.The seal between the
Après la sortie du projectile 6, ma douille 2 est arrêtée dans son mouvement par les butées 36, tandis que le canon continue son mouvement vers l'avant, comprimant le ressort de rappel 27, comme indiquée dans la figure 16.After the exit of the
Par le mouvement de la douille 2 vers l'avant, l'ergot 13 est dégagé de la came 43 du poussoir 41, comme représenté dans la figure 15, qui de ce fait ne retient plus le levier basculant 37 qui par conséquent pivote sous l'action du ressort 38 jusqu'à ce que l'extrémité avant 39 touche le canon.By the movement of the
De cette façon le levier basculant 37 sert de butée pour l'épaulement 30 quand le canon 19 recule de son mouvement vers l'avant sous l'action du ressort 27 et arrête le canon 19 dans une position avancée comme représenté dans la figure 17 pour permettre l'éjection de la cartouche 1 tirée.In this way, the rocking
En même temps la came 43 tombe derrière l'ergot avant 13 et empêche le recul de la douille 2 et le piston 7 est déformé par la pression de gaz ce qui permet que le piston 7 reste bloqué dans la douille 2 par frottement et supprime le besoin d'une butée d'arrêt entre la douille 2 et le piston 7.At the same time the
La cartouche vide 1 n'étant plus maintenue par les butées 34, elle est éjectée à travers la fenêtre d'éjection 31 sous l'action du transporteur 33 du chargeur 20 qui pousse les cartouches 1 suivantes vers la sortie 21 du chargeur 20 comme représenté dans les figures 18 et 19.The
Le mouvement de la nouvelle cartouche 1 fera de nouveau monter le poussoir 41 qui de ce fait libérera l'arrêtoir du canon 19 qui pourra reculer pour appuyer la nouvelle cartouche 1 contre l'élément d'appui 22 afin d'obtenir une nouvelle situation de départ, prêt à tirer une nouvelle foi, comme représenté dans la figure 10.The movement of the
Il est clair que l'invention n'est pas seulement limitée à des armes à feu avec une munition destinée à lancer un projectile à létalité réduite, mais peut aussi être appliquée pour d'autres types de munition.It is clear that the invention is not only limited to firearms with a munition for launching a reduced lethal projectile, but can also be applied for other types of ammunition.
Bien que les douilles 2 et les pistons 7 de la cartouche 1 sont fabriqués de préférence en matière plastique, il n'est pas exclu de les fabriquer en d'autres matières.Although the
Une arme à feu selon l'invention peut également être réalisée sous forme d'un fusil, lance grenade, ou d'autres types d'armes.A firearm according to the invention can also be made in the form of a rifle, grenade launcher, or other types of weapons.
Le projectile 6 est de préférence complètement logé dans la chambre basse pression 3 de la cartouche 1, mais peut également dépasser au moins partiellement l'ouverture avant de la chambre basse pression 3 de la cartouche 1.The
L'arrêtoir du canon et le mécanisme de blocage de cet arrêtoir peuvent bien entendu être réalisé d'une autre manière que décrite.The gun stop and the locking mechanism of this stop can of course be realized in another way than described.
L'étanchéité entre une cartouche 1 et le canon 19 peut être réalisée sous d'autres formes que par l'emboîtement de la partie avant 15 de la douille 2 dans l'entrée du canon 6.The seal between a
Il est évident que l'invention n'est nullement limitée à l'exemple décrit ci-avant mais que de nombreuses modifications peuvent être apportées à l'arme et à la munition décrite ci-avant sans sortir du cadre de l'invention telle que définie dans les revendications suivantes.It is obvious that the invention is not limited to the example described above but that many modifications can be made to the weapon and ammunition described above without departing from the scope of the invention as defined in the following claims.
