Description
Le secteur technique de la présente invention est celuiThe technical sector of the present invention is that
des dispositifs permettant de séparer automatiquement les maillons, par exemple les maillons des munitions de 25 mm après le tir des munitions correspondantes. devices for automatically separating the links, for example the links of 25 mm ammunition after firing of the corresponding ammunition.
Les maillons sont reliés entre eux de façon connue par un système de collerettes et de rainures complémentaires. Chaque maillon est constitué de deux pièces semi-cylindriques reliées entre elles de façon fixe. La première pièce, la pièce de maintien, porte des collerettes et la seconde pièce, 10 la calotte, porte des rainures. Deux maillons consécutifs sont reliés en engageant les collerettes de la pièce de maintien du premier maillon dans les rainures de la calotte du second maillon. Une fois les munitions engagées dans les maillons, ceux-ci sont virtuellement inséparables. The links are connected together in a known manner by a system of flanges and complementary grooves. Each link consists of two semi-cylindrical parts connected to each other in a fixed manner. The first part, the retaining part, carries flanges and the second part, the cap, carries grooves. Two consecutive links are connected by engaging the flanges of the holding part of the first link in the grooves of the cap of the second link. Once the ammunition is engaged in the links, they are virtually inseparable.
Le comportement des maillons ne pose aucun problème lorsque l'arme est montée sur un afft. Par contre, si l'arme est montée dans une tourelle les maillons doivent bien souvent être évacués à l'extérieur étant donné le peu de place disponible dans cette tourelle. The behavior of the links poses no problem when the weapon is mounted on a mount. On the other hand, if the weapon is assembled in a turret the links must very often be evacuated outside given the little space available in this turret.
Actuellement, aucun dispositif ne permet de séparer automatiquement les maillons de 25 mm après le tir. Les maillons ressortent de l'arme après le tir toujours en bande et liés entre eux. Ils sont guidés vers l'extérieur de la tourelle par des couloirs souples et leur déplacement 25 automatique se fait grâce à la poussée exercée par l'arme. Currently, no device allows the 25 mm links to be automatically separated after firing. The links emerge from the weapon after firing, always in a band and linked together. They are guided towards the outside of the turret by flexible corridors and their automatic displacement is effected by the thrust exerted by the weapon.
A l'extérieur, les maillons sortent par deux sorties d'éjection, une haute et une basse. Les maillons sortant par l'éjection haute de l'arme se séparent naturellement lors de leur chute sous l'effet de la pesanteur. Les maillons sortant 30 par l'éjection basse restent en bande. Outside, the links exit through two ejection outlets, a high and a low. The links exiting by the high ejection of the weapon naturally separate when they fall under the effect of gravity. The outgoing links 30 by the low ejection remain in band.
Les maillons sortant de l'éjection basse restent liés entre eux, ce qui rend leur stockage après le tir difficile car volumineux. Cela nécessite donc l'éjection des bandes de maillons à l'extérieur du véhicule. Les maillons en bande 35 finissent par s'agglomérer en boule sur le toit du véhicule et se décrochent en fonction des secousses provoquées par les obstacles rencontrés par le véhicule. Cette façon de faire pose un problème et aucune solution n'a été proposée à ce jour. De plus, le ou les servants de la tourelle ne sont jamais en mesure d'intervenir manuellement pour séparer ces maillons. C'est le but de l'invention que de remédier à ces 5 inconvénients en proposant un dispositif passif, simple, robuste et fiable, permettant de séparer deux maillons consécutifs d'une chaîne sortant d'une arme après le tir des munitions. L'invention a donc pour objet un dispositif de séparation 10 des maillons d'une chaîne de maillons à munitions sortant d'une arme après le tir, caractérisé en ce qu'il est constitué par un moyen élastique solidaire de l'arme et placé à proximité de la sortie de la chaîne, apte à faire pivoter chaque maillon par rapport au suivant de façon à provoquer le 15 désaccouplement de leur charnière de liaison. The links coming out of the low ejection remain linked together, which makes their storage after firing difficult because of their size. This therefore requires the ejection of the link strips from the outside of the vehicle. The strip links 35 end up agglomerating in a ball on the roof of the vehicle and fall off according to the tremors caused by the obstacles encountered by the vehicle. This way of doing things poses a problem and no solution has been proposed to date. In addition, the turret (s) are never able to intervene manually to separate these links. It is the object of the invention to remedy these 5 drawbacks by proposing a passive, simple, robust and reliable device, making it possible to separate two consecutive links from a chain coming out of a weapon after the ammunition has been fired. The invention therefore relates to a device 10 for separating the links of a chain of ammunition links leaving a weapon after firing, characterized in that it is constituted by an elastic means secured to the weapon and placed near the outlet of the chain, able to rotate each link relative to the next so as to cause the uncoupling of their connecting hinge.
Selon une caractéristique de l'invention, le moyen élastique est constitué d'une languette, par exemple en acier à ressort, et d'un support fixé au niveau de la sortie du couloir à maillon de l'arme. According to a characteristic of the invention, the elastic means consists of a tongue, for example made of spring steel, and of a support fixed at the level of the exit from the link corridor of the weapon.
Selon une autre caractéristique de l'invention, le support de la languette comprend un élément élastique tel que des rondelles Belleville. According to another characteristic of the invention, the support of the tongue comprises an elastic element such as Belleville washers.
Selon encore une autre caractéristique, le moyen élastique est fixé à l'arme de telle façon que le maillon 25 sortant libre entame sa rotation par rapport au maillon suivant maintenu dans l'arme. According to yet another characteristic, the elastic means is fixed to the weapon so that the free exiting link 25 begins to rotate relative to the next link held in the weapon.
Selon encore une autre caractéristique de l'invention, le moyen élastique présente une courbure épousant sensiblement la courbure des maillons. According to yet another characteristic of the invention, the elastic means has a curvature substantially matching the curvature of the links.
Un premier avantage du dispositif selon l'invention est de permettre de séparer les maillons de manière continue et passive au fur et à mesure de leur sortie de l'arme, ce qui n'impose aucune manipulation supplémentaire aux opérateurs. A first advantage of the device according to the invention is that it makes it possible to separate the links continuously and passively as they exit the weapon, which does not impose any additional manipulation on the operators.
Un second avantage du dispositif selon l'invention est 35 qu'il permet le stockage des maillons en vrac après utilisation des munitions, ce qui prend moins de place que le stockage des maillons en chaîne. A second advantage of the device according to the invention is that it allows the storage of loose links after use of the ammunition, which takes up less space than the storage of chain links.
D'autres avantages, détails et caractéristiques de l'invention apparaîtront plus clairement à la lecture du complément de description donné ci-après à titre d'illustration en relation avec des dessins sur lesquels: - la figure 1 représente l'alimentation d'une arme par bande de munitions, - la figure 2 est une coupe montrant le dispositif selon l'invention, - la figure 3 montre la fixation du dispositif sur 10 l'arme, une vue en perspective de deux maillons reliés entre eux et dépourvus de munition, et -les figures 4 et 5 montrent le fonctionnement du dispositif selon l'invention. Other advantages, details and characteristics of the invention will appear more clearly on reading the additional description given below by way of illustration in relation to the drawings in which: - Figure 1 shows the supply of a weapon by strip of ammunition, - Figure 2 is a section showing the device according to the invention, - Figure 3 shows the attachment of the device to the weapon, a perspective view of two links connected together and devoid of ammunition , and FIGS. 4 and 5 show the operation of the device according to the invention.
Sur la figure 1, on a représenté une arme 1, par exemple 15 de calibre 25 mm, alimentée par bande de munitions selon deux modes représentés pour des raisons de commodité sur la même figure. Sur la partie supérieure de la figure, la bande de munitions 2 pénètre dans un couloir d'alimentation haut 20 c'est-à-dire que l'ouverture 4 des maillons est dirigée vers le bas. A la sortie de l'arme, comme représenté sur la figure, les maillons se séparent naturellement sous l'effet de la gravité puisque les douilles vides ont été éjectées. On voit également les deux parties constitutives des maillons, 25 la pièce de maintien 10 et la calotte 11. In Figure 1, there is shown a weapon 1, for example 15 of 25 mm caliber, supplied by ammunition strip in two modes shown for convenience in the same figure. In the upper part of the figure, the ammunition strip 2 enters a top feed corridor 20, that is to say that the opening 4 of the links is directed downwards. At the exit of the weapon, as shown in the figure, the links separate naturally under the effect of gravity since the empty casings have been ejected. We also see the two constituent parts of the links, the holding part 10 and the cap 11.
Sur la partie inférieure de la figure, la bande de munition 3 pénètre dans un couloir d'alimentation bas. In the lower part of the figure, the ammunition strip 3 enters a low supply corridor.
L'ouverture 4 des maillons est alors, dans ce cas, dirigée vers le haut. Comme représenté sur la figure, à la sortie 30 basse 5 de l'arme, les maillons ne se séparent pas et restent en chaîne. The opening 4 of the links is then, in this case, directed upwards. As shown in the figure, at the bottom outlet 5 of the weapon, the links do not separate and remain in chain.
La figure 2 montre le dispositif 6 selon l'invention. Le dispositif est fixé sur l'arme 1 au niveau de la sortie basse 5 des maillons. Ce dispositif est constitué d'une languette 35 7, en acier à ressort, montée sur des rondelles Belleville 8, le tout fixé à l'arme 1 par l'intermédiaire d'une vis 9, les rondelles et la vis constituant un support. Figure 2 shows the device 6 according to the invention. The device is attached to the weapon 1 at the lower outlet 5 of the links. This device consists of a tongue 35 7, made of spring steel, mounted on Belleville washers 8, the whole fixed to the weapon 1 by means of a screw 9, the washers and the screw constituting a support.
Sur la figure 3, on voit le dispositif en perspective avec une chaîne 3 de maillons. La chaîne de maillons 3 sort de l'arme 1 par la sortie basse 5. La pièce de maintien 10 de chaque maillon, en sortant de l'arme, vient buter contre la 5 languette 7 et glisser vers le haut, ce qui dégage les collerettes, non représentées mais comme expliqué précédemment, portées par la calotte 11, des rainures complémentaires portées par la pièce de maintien 10 du maillon suivant, dans lesquelles elles sont engagées. Ce mode 10 de liaison entre maillons est bien connu et il n'est pas nécessaire de donner plus de précision. In Figure 3, we see the device in perspective with a chain 3 of links. The chain of links 3 leaves the weapon 1 via the low outlet 5. The holding piece 10 of each link, on leaving the weapon, abuts against the tongue 5 and slides upwards, which releases the flanges, not shown but as explained above, carried by the cap 11, complementary grooves carried by the holding part 10 of the following link, in which they are engaged. This mode of connection between links is well known and it is not necessary to give more precision.
Les figures 4 et 5 montrent le fonctionnement du dispositif selon l'invention. Figures 4 and 5 show the operation of the device according to the invention.
Sur la figure 4, la pièce de maintien 10 approche de la 15 languette 7 en sortant de l'arme 1. La chaîne de maillons, sur cette figure, est toujours complète. In FIG. 4, the holding part 10 approaches the tongue 7 while leaving the weapon 1. The chain of links, in this figure, is always complete.
Sur la figure 5 sont représentées deux positions d'un maillon 12 qui est détaché de la chaîne par le dispositif selon l'invention. On y voit qu'au fur et à mesure de 20 l'avancée de la chaîne, la pièce de maintien 10 entame un pivotement progressif qui permet à la calotte 11 de se dégager de la pièce de maintien du maillon suivant. On a représenté sur cette figure une première position du maillon 12 en 10' et 11' et une seconde position en 10" et 11i. Ce 25 pivotement s'effectue grâce au maintien temporaire du maillon suivant dans l'arme. Ainsi, on provoque par rotation le désaccouplement de la charnière de liaison de deux maillons consécutifs et ainsi de suite. Bien entendu, la forme de la languette 7 et sa courbure sont prévues pour assurer le 30 pivotement d'un maillon avant que le maillon suivant soit libéré. D'autres variantes sont évidemment possibles sans pour autant quitter le cadre de l'invention. In Figure 5 are shown two positions of a link 12 which is detached from the chain by the device according to the invention. It can be seen there that as the chain advances, the retaining piece 10 begins a progressive pivoting which allows the cap 11 to disengage from the retaining piece of the next link. This figure shows a first position of the link 12 in 10 'and 11' and a second position in 10 "and 11i. This pivoting is effected by temporarily holding the next link in the weapon. Thus, it causes by rotation the uncoupling of the connecting hinge of two consecutive links and so on. Of course, the shape of the tongue 7 and its curvature are provided to ensure the pivoting of a link before the next link is released. 'other variants are obviously possible without departing from the scope of the invention.
