Description
MITRAILLEUSE MACHINE GUN
Objet de l'invention Object of the invention
[0001] La présente invention se rapporte au système de percussion d'une arme à feu fonctionnant à culasse ouverte. The present invention relates to the percussion system of a gun operating open yoke.
Etat de la technique State of the art
[0002] Pour une mitrailleuse tirant en culasse ouverte ou avec une bande de munitions, l'énergie de percussion est généralement stockée sous forme d'énergie potentielle de compression du ressort récupérateur, sous forme d'énergie cinétique des pièces mobiles, ou dans un ressort pré-comprimé entre le percuteur et le verrou. For a machine gun pulling in an open bolt or with a band of ammunition, the percussion energy is generally stored as a potential energy of compression of the recuperator spring, in the form of kinetic energy of the moving parts, or in a pre-compressed spring between the striker and the lock.
[0003] En effet, dans le cas d'un fonctionnement à culasse ouverte, le tir est déclenché par la libération des pièces mobiles, initialement disposées en position arrière, contrairement à la situation d'un fusil fonctionnant à culasse fermée où le tir est déclenché par la libération d'un chien par la queue de détente, les pièces mobiles étant initialement au repos, à l'avant, culasse verrouillée. Indeed, in the case of an open-head operation, the firing is triggered by the release of the moving parts, initially arranged in the rear position, unlike the situation of a rifle operating with closed yoke where the shot is triggered by the release of a dog by the trigger tail, the moving parts being initially at rest, in the front, bolt locked.
[0004] Par exemple, dans le cas de la mitrailleuse FN Minimi®, le percuteur est actionné par le mouvement vers l'avant des pièces mobiles après verrouillage de la culasse par le verrou. [0005] Néanmoins, la percussion induite par le mouvement de retour des pièces mobile présente l'inconvénient de dépendre du rendement du cycle de fonctionnement de l'arme. Ainsi, en cas de fonctionnement en conditions difficiles (sable, boue), la vitesse des pièces mobiles est ralentie avant d'arriver en position culasse fermée. L'énergie pour percuter peut alors ne plus être suffisante. For example, in the case of the machine gun FN Minimi ® , the firing pin is actuated by the forward movement of the moving parts after locking the cylinder head by the lock. However, the percussion induced by the return movement of the moving parts has the disadvantage of depending on the efficiency of the operating cycle of the weapon. Thus, in case of operation in difficult conditions (sand, mud), the speed of moving parts is slowed down before arriving in closed cylinder head position. The energy to hit may then no longer be sufficient.
Résumé de l'invention Summary of the invention
[0006] Un premier aspect de l'invention se rapporte à une arme à feu, de préférence une mitrailleuse, opérant à culasse ouverte comprenant un mécanisme de commande de tir disposé sous une carcasse dans laquelle coulissent des pièces mobiles déplacées vers l'arrière par récupération de gaz, et vers l'avant par un ressort récupérateur, la récupération des gaz et le ressort récupérateur étant disposés sous l'axe du canon, ladite arme à feu comprenant un chien disposé, en position chargée, au-dessus de l'axe du canon, et la libération dudit chien étant indépendante du mécanisme de commande de tir. [0006] A first aspect of the invention relates to a firearm, preferably a machine gun, operating an open breech comprising a firing control mechanism disposed under a carcass in which displaced moving parts slide. rearward by gas recovery, and forwards by a recuperative spring, the recovery of the gases and the recuperating spring being disposed under the axis of the barrel, said firearm comprising a dog arranged, in a loaded position, to above the axis of the barrel, and the release of said dog being independent of the firing control mechanism.
[0007] De préférence, les pièces mobiles comprennent une came actionnant la libération du chien lors du verrouillage de la culasse. [0007] Preferably, the moving parts comprise a cam actuating the release of the dog during the locking of the cylinder head.
[0008] Avantageusement, une gâchette est disposée de façon à commander la libération du chien lorsque la came déplace ladite gâchette. Advantageously, a trigger is arranged to control the release of the dog when the cam moves said trigger.
[0009] De préférence, le chien comprend une surface de glissement concave orientée vers les pièces mobiles. [0009] Preferably, the dog comprises a concave sliding surface oriented towards the moving parts.
[0010] Avantageusement, la glissière comprend à son extrémité arrière inférieure, une came disposée de façon à prendre appui sur à proximité de l'extrémité inférieure de la surface de glissement lors d'une première section de recul de la glissière. Advantageously, the slide comprises at its lower rear end, a cam arranged to bear on near the lower end of the sliding surface during a first recoil section of the slide.
[0011] De préférence, la glissière comprend à son extrémité arrière supérieure, une came disposée de façon à prendre appui sur la surface de glissement lors d'une seconde section de recul de la glissière. Preferably, the slide comprises at its upper rear end, a cam arranged to bear on the sliding surface during a second recoil section of the slide.

[0019] La présente invention concerne un mécanisme 1 de chien adapté aux armes à feu opérant à culasse ouverte, en mode automatique ou semi-automatique. Dans une telle arme, le chargement par bande par le haut de la carcasse oblige le concepteur à placer la récupération des gaz et le ressort récupérateur sous l'axe du canon 5 plutôt que au-dessus de celui-ci. The present invention relates to a dog mechanism 1 adapted to open-head firearms operating in automatic or semi-automatic mode. In such a weapon, the loading by band from the top of the carcass forces the designer to place the recovery of gases and the recuperator spring under the axis of the barrel 5 rather than above it.
[0020] La conséquence de ce positionnement est qu'il est difficile de placer un mécanisme de chien intégré à la sous-garde, celle-ci étant séparée du percuteur par les ressort récupérateur et le bas des pièces mobiles dans la prolongation du piston de récupération des gaz. The consequence of this positioning is that it is difficult to place a dog mechanism integrated in the guard, the latter being separated from the striker by the recuperator spring and the bottom of the moving parts in the extension of the piston of gas recovery.
[0021] La présente invention tire parti du fait que lors du fonctionnement à culasse ouverte, le déclenchement du tir (début de cycle) n'est pas lié à la percussion d'une cartouche dans la chambre 4, mais à la libération des pièces mobiles 2. Dans ces conditions, il n'est plus nécessaire d'intégrer le mécanisme de chien dans la sous-garde, en lien mécanique avec le mécanisme de détente. The present invention takes advantage of the fact that during operation with open breech, the firing trigger (beginning of cycle) is not related to the percussion of a cartridge in the chamber 4, but the release of the parts 2. Under these conditions, it is no longer necessary to integrate the dog mechanism in the sub-guard, in mechanical connection with the trigger mechanism.
[0022] Au contraire, dans la présente invention, la libération du chien 14 est intégralement contrôlée par le mouvement de la glissière 7, ce qui assure une synchronisation optimale entre le verrouillage de la culasse par le verrou 8 et la percussion. On the contrary, in the present invention, the release of the dog 14 is integrally controlled by the movement of the slide 7, which ensures optimum synchronization between the locking of the bolt by the bolt 8 and the percussion.
[0023] Le mécanisme de chien 1 n'étant plus lié au mécanisme de détente 3, il est alors possible de positionner le mécanisme de chien 1 au-dessus de l'axe du canon plutôt que en-dessous de cet axe. The dog mechanism 1 is no longer linked to the trigger mechanism 3, it is then possible to position the dog mechanism 1 above the axis of the barrel rather than below this axis.
[0024] La figure 1 montre un exemple de mitrailleuse selon l'invention, sans la carcasse, pour montrer les éléments de celle-ci. On y voit un mécanisme de chien 1 disposé au-dessus de l'axe du canon 5 et fonctionnant de façon totalement autonome. En particulier, aucun mécanisme ne lie le mécanisme de chien 1 au mécanisme de détente 3. Figure 1 shows an example of a machine gun according to the invention, without the carcass, to show the elements thereof. It shows a dog mechanism 1 disposed above the axis of the barrel 5 and operating completely autonomously. In particular, no mechanism links the dog mechanism 1 to the trigger mechanism 3.
[0025] Les figures 2 à 7 montrent des vues détaillées des différents éléments du mécanisme de percussion lors d'un cycle de la mitrailleuse. A la figure 1, les pièces mobiles sont au repos en attente d'un tir. Dans cette position, le mécanisme de chien 1 est pratiquement hors du chemin de la glissière 7 et permet son libre mouvement vers l'avant, tel que représenté à la figure 3. Figures 2 to 7 show detailed views of the various elements of the percussion mechanism during a cycle of the machine gun. In Figure 1, the moving parts are at rest waiting for a shot. In this position, the dog mechanism 1 is virtually out of the path of the slide 7 and allows its free movement forward, as shown in Figure 3.
[0026] La figure 4 montre la fin du mouvement de la glissière 7 vers l'avant, à l'instant du verrouillage. A cet instant, la came 10 pousse la gâchette 13 vers l'avant, ce qui libère le chien 14 qui se met à tourner autour de son axe sous l'effet du ressort de chien 16. Figure 4 shows the end of the movement of the slide 7 forward, at the moment of locking. At this moment, the cam 10 pushes the trigger 13 forward, which releases the dog 14 which starts to rotate about its axis under the effect of the dog spring 16.
[0027] La figure 5 représente les premiers instants après percussion, au début du recul des pièces mobiles 2. A cet instant, la glissière 7 reculant, la came 11 pousse sur la surface de glissement 15 commençant à comprimer le ressort de chien. Notons que le point de contact 18 entre la glissière 7 et le chien 14 est le plus éloigné possible de l'axe de rotation du chien, de façon réduire le choc subi par le chien 14, et donc son usure et sa fatigue, réduisant ainsi le risque de rupture à long terme. La présence de la came arrondie 11 permet de réduire encore l'usure et la fatigue. Figure 5 shows the first moments after percussion at the beginning of the recoil of the moving parts 2. At this time, the slide 7 retreating, the cam 11 pushes on the sliding surface 15 beginning to compress the dog spring. Note that the point of contact 18 between the slide 7 and the dog 14 is the furthest possible from the axis of rotation of the dog, so as to reduce the shock suffered by the dog 14, and therefore its wear and fatigue, thus reducing the risk of long-term disruption. The presence of the rounded cam 11 further reduces wear and fatigue.
[0028] La figure 6 représente la suite du cycle, avec les pièces mobiles à une première position intermédiaire. On y observe que le percuteur s'est effacé de la glissière 7. Dans cette phase de recul, le verrou 4 reste encore fixé à la chambre 4 tandis que la glissière 7 recule déjà vers l'arrière. Figure 6 shows the continuation of the cycle, with the moving parts at a first intermediate position. It is observed that the striker has cleared the slide 7. In this recoil phase, the latch 4 is still attached to the chamber 4 while the slide 7 is already backward.
[0029] La figure 7 représente la suite du cycle, les pièces mobiles 2 étant dans une seconde position intermédiaire. A cette position, la glissière 7 pousse sur la surface de glissement via une seconde came 9 disposée cette fois dans la partie supérieure de la glissière. En effet, à cette position, la distance entre l'axe du chien et la came 9 est suffisamment élevée pour que l'accélération du chien soit limitée. Figure 7 shows the continuation of the cycle, the moving parts 2 being in a second intermediate position. In this position, the slide 7 pushes on the sliding surface via a second cam 9, this time arranged in the upper part of the slideway. Indeed, at this position, the distance between the axis of the dog and the cam 9 is high enough for the acceleration of the dog is limited.
[0030] La dynamique de relevage du chien est optimisée par l'adoption d'une surface de glissement 15 du chien au contact avec la glissière 7 concave. Cette forme permet en effet, combinée à la présence d'une came 11 dans la partie inférieure de l'arrière de la glissière 7, de prendre d'abord appui sur une surface de la glissière opposée à la position du chien, ce qui augmente le bras de levier de relevage et réduit le choc associé à celui-ci. La courbure de cette surface, sans point anguleux rend aussi ce mouvement plus continu et évite des chocs pouvant induire une fatigue du matériau. The raising dynamics of the dog is optimized by the adoption of a sliding surface 15 of the dog in contact with the concave slide 7. This shape makes it possible, combined with the presence of a cam 11 in the lower part of the rear of the slide 7, to first bear on a surface of the slide opposite to the position of the dog, which increases the lift lever arm and reduces the shock associated with it. The curvature of this surface, without angular point also makes this movement more continuous and avoids shocks that can induce fatigue of the material.
[0031] La fin du mouvement de relevage du chien est assurée par une came 9 située sur la face supérieure de la glissière 7. Cette came 9 est en retrait par rapport à la came inférieure 11 de façon à ce que la came 11 agisse en début de relevage, et la came 9 en fin de relevage. The end of the raising movement of the dog is provided by a cam 9 located on the upper face of the slide 7. This cam 9 is set back from the lower cam 11 so that the cam 11 acts at the beginning of raising, and the cam 9 at the end of lifting.
[0032] Notons que le positionnement du mécanisme de chien dans la partie supérieur de l'arme permet non seulement de s'affranchir du problème de l'encombrement du ressort récupérateur et des pièces mobiles dans le cas d'un chargement par le dessus, mais aussi permet de réduire l'encombrement de la sous- garde, ce qui permet le design de sous-garde plus compacte. Note that the positioning of the dog mechanism in the upper part of the weapon allows not only to overcome the problem of congestion recovery spring and moving parts in the case of a load from above, but also reduces the clutter of the under guard, allowing the design of more compact sub-guard.
