Abstract

The device (5) has links (M1, M2) pivotingly mounted with respect to each other at an angle, where each link has side clamps (2) and a middle clamp (1). The middle clamp pivots in grooves of the side clamps. The links are placed in a position relative to the device such that the links are rotated by gravity exerting on the link (M1) to ensure unlocking and disengaging of the link (M1). Elastic plates (10) ensure the swinging of the link and the fins (11) guide and maintain the link (M2) during the swinging of the link (M1).

Description

Le domaine technique de l'invention est celui des dispositifs d'alimentation d'une arme en munitions et en particulier celui des dispositifs permettant de séparer les maillons les uns des autres à la sortie de l'arme après le tir de la munition.The technical field of the invention is that of devices for feeding an ammunition weapon and in particular that of devices for separating the links from each other at the exit of the weapon after firing the ammunition.

Les munitions tirées par les armes de moyen calibre (calibre compris entre 20mm et 50mm) sont généralement assemblées sur des chaînes ou bandes de maillons. Ces bandes permettent de faciliter l'introduction des munitions dans l'arme. Les munitions sont stockées en magasin avec leur bande. La bande permet de les conduire à l'arme en suivant des couloirs d'alimentation. Le système d'alimentation de l'arme amène ainsi les munitions les unes après les autres en regard de la chambre de l'arme où la munition correctement positionnée est extraite de sa bande pour être tirée.Ammunition fired by medium-caliber weapons (caliber between 20mm and 50mm) is usually assembled on chains or bands of links. These bands make it easier to introduce ammunition into the weapon. Ammunition is stored in stores with their band. The band allows them to be driven to the gun by following feeding lanes. The weapon's feeding system thus brings the ammunition one after the other opposite the chamber of the weapon where the correctly positioned ammunition is extracted from its band to be fired.

La munition peut être extraite de son maillon à l'entrée dans l'arme et être ensuite prise en charge par l'arme pour être mise en place dans la chambre. La bande sort ensuite de l'arme débarrassée des munitions.The ammunition can be extracted from its link at the entrance to the weapon and then be taken over by the weapon to be put in place in the room. The band then leaves the weapon cleared of ammunition.

Dans certains systèmes d'armes, notamment les systèmes montés sur tourelle et pour lesquels il existe un problème d'encombrement à l'intérieur de la tourelle, il est nécessaire d'évacuer les bandes de maillons à l'extérieur de la tourelle ou bien de les stocker dans la tourelle avec un volume le plus réduit possible.In some weapon systems, such as turret mounted systems where there is a congestion problem inside the turret, it is necessary to evacuate the link strips outside the turret or store them in the turret with as little volume as possible.

Cependant les bandes de maillons toujours liés entre eux s'agglomèrent et forment des blocs solidaires de la tourelle et qui peuvent gêner la mise en oeuvre de cette dernière.However, the bands of links still interconnected agglomerate and form blocks integral with the turret and which can hinder the implementation of the latter.

On a donc cherché à mettre au point des dispositifs permettant d'assurer une séparation des différents maillons de la bande à la sortie de l'arme ou de la tourelle.It has therefore sought to develop devices to ensure a separation of different links of the band at the exit of the weapon or turret.

Bien entendu une solution pour un dispositif de séparation de maillons va être spécifique d'une architecture de bande de maillons.Of course, a solution for a link separation device will be specific to a link band architecture.

L'invention vise plus particulièrement un dispositif qui est destiné à séparer des maillons d'une bande dans laquelle les maillons sont montés pivotant angulairement les uns par rapport aux autres, une position de pivotement relatif d'un premier maillon par rapport au maillon qui le suit permettant le décrochage du premier maillon.The invention more particularly relates to a device which is intended to separate links of a strip in which the links are mounted to pivot angularly relative to each other, a relative pivoting position of a first link with the link that follows the stall of the first link.

Une telle structure de bande de maillons est bien connue de l'Homme du Métier et décrite notamment dans la norme OTAN: STANAG n° 4173 pour les munitions au calibre 25 x 137 mm.Such a link band structure is well known to those skilled in the art and described in particular in NATO standard: STANAG No. 4173 for ammunition at 25 x 137 mm.

La figure la montre ainsi deux maillons M1, M2 d'une telle bande séparés l'un de l'autre tandis que la figure 1b montre ces maillons assemblés.The figure thus shows two links M1, M2 of such a strip separated from one another while the figure 1b shows these assembled links.

On voit que chaque maillon comporte un étrier médian 1 et deux étriers latéraux 2. Chaque étrier a une forme partiellement cylindrique de façon à recevoir une munition. L'étrier médian 1 du maillon M2 comporte des bourrelets circulaires 3 qui coopèrent avec des rainures circulaires 4 portées par les étriers latéraux 2 du maillon M1.We see that each link comprises a median stirrup 1 and two side stirrups 2. Each stirrup has a partially cylindrical shape to receive a munition. The median stirrup 1 of the link M2 comprises circular beads 3 which cooperate with circular grooves 4 carried by the lateral stirrups 2 of the link M1.

Ainsi, comme on le voit sur la figure 1b lorsque les maillons M1 et M2 sont assemblés, l'étrier médian de l'un se positionne entre les étriers latéraux de l'autre et un pivotement relatif de M1 par rapport à M2 est possible par la coopération des bourrelets 3 avec les rainures 4.So, as we see on the figure 1b when the links M1 and M2 are assembled, the middle stirrup of one is positioned between the lateral stirrups of the other and a relative pivoting of M1 with respect to M2 is possible by the cooperation of the beads 3 with the grooves 4.

On forme ainsi des bandes de maillons ayant une souplesse permettant la conduite des munitions dans les couloirs de l'arme.Thus bands of links are formed with a flexibility to conduct the ammunition in the corridors of the weapon.

Lorsque les munitions sont mises en place sur la bande elles n'empêchent pas les maillons de pivoter les uns par rapport aux autres, mais elles jouent le rôle de charnière et de lien entre les étriers latéraux d'un maillon et l'étrier médian d'un maillon suivant et ce quelle que soit la courbure de la bande de munitions.When the ammunition is placed on the band they do not prevent the links from pivoting relative to each other, but they act as a hinge and link between the side stirrups of a link and the median stirrup. a next link and this regardless of the curvature of the ammunition strip.

Par contre, lorsque les munitions sont retirées, il devient possible de séparer les maillons après les avoir fait pivoter jusqu'à ce qu'ils aient atteint une position angulaire correcte l'un par rapport à l'autre, permettant ainsi le démontage de la bande.On the other hand, when the ammunition is removed, it becomes possible to separate the links after having pivoted them until they have reached a correct angular position with respect to each other, thus allowing the disassembly of the bandaged.

On a proposé dans le brevet FR2849498 un dispositif de séparation de maillons dans lequel une languette élastique est disposée en dessous de la sortie de la bande hors de la tourelle. Cette languette a pour objet, en guidant vers le haut le maillon sortant, de le faire pivoter par rapport au maillon suivant ce qui permet de séparer les maillons les uns des autres.It has been proposed in the patent FR-2849498 a link separating device in which an elastic tongue is disposed below the exit of the strip from the turret. This tongue is intended, by guiding upwards the outgoing link, to rotate it relative to the next link which allows to separate the links from each other.

Ce dispositif est destiné à assurer la désolidarisation des maillons pour un système d'arme qui comporte une alimentation de deux types de munitions différents (munitions perforantes et munitions explosives). Ces systèmes d'armes sont bien connus et comportent deux couloirs d'alimentation distincts. Les maillons sortent alors suivant deux sorties d'éjection différentes.This device is intended to ensure the separation of the links for a weapon system which comprises a supply of two different types of ammunition (piercing ammunition and explosive ordnance). These weapons systems are well known and have two distinct supply corridors. The links then come out according to two different ejection outlets.

Le brevet FR-2849498 montre schématiquement ces deux sorties des maillons. Les maillons qui sortent en partie basse sont orientés avec leurs étriers latéraux et médians ouverts vers le haut. Ils ne peuvent pivoter naturellement par l'action de la gravité et des moyens spécifiques tels que décrits par FR-2849498 doivent être prévus pour séparer les maillons.The patent FR-2849498 schematically shows these two outputs of the links. The links that come out in the lower part are oriented with their side and median stirrups open upwards. They can not rotate naturally by the action of gravity and specific means as described by FR-2849498 must be provided to separate the links.

Les maillons qui sortent en partie haute sont orientés avec leurs étriers latéraux et médians ouverts vers le bas. L'effet de la gravité conduit naturellement le maillon sortant à pivoter par rapport au maillon suivant lorsqu'il ne se trouve plus maintenu par le couloir d'alimentation. Ainsi le brevet FR2849498 propose de laisser les maillons se séparer seuls par le simple effet de la gravité. On prévoit généralement un simple couloir de guidage qui permet d'écarter les maillons de l'arme et de les laisser se séparer à distance.The links that come out in the upper part are oriented with their side stirrups and medians open down. The effect of gravity naturally causes the outgoing link to pivot relative to the next link when it is no longer maintained by the feed corridor. So the patent FR-2849498 proposes to let the links separate by the simple effect of gravity. A simple guiding corridor is generally provided which allows the links of the weapon to be separated and to allow them to separate at a distance.

Cependant, cette solution très simple présente des inconvénients.However, this very simple solution has disadvantages.

On constate en effet que le simple détachement naturel des maillons les uns des autres par l'effet de la gravité n'est pas fiable. Des frottements inter maillons existent et diffèrent d'un maillon à l'autre. La séparation n'est donc pas systématique dès la sortie des maillons hors du couloir de guidage. Par ailleurs l'effet des forces de gravité sur les maillons varie en fonction du site de tir de l'arme. Il en résulte un problème au niveau de la fiabilité du démaillonnage lorsqu'on n'utilise que l'effet de la gravité pour séparer les maillons.It can be seen that the simple natural detachment of links from each other by the effect of gravity is not reliable. Inter-link friction exists and differs from one link to another. The separation is not systematic when leaving the links out of the guide corridor. In addition, the effect of gravitational forces on the links varies according to the weapon's firing site. This results in a problem in the reliability of unmaking when only the effect of gravity is used to separate the links.

Enfin, le dispositif connu de FR-2849498 comporte une longueur de couloir importante qui encombre la zone dédiée à l'évacuation des maillons, aussi bien pour l'évacuation partie haute que pour l'évacuation partie basse.Finally, the known device of FR-2849498 has a long corridor length that clutters the area dedicated to the removal of the links, both for the high part evacuation as for the low part evacuation.

Il y a un risque non négligeable de formation d'un groupe de maillons qui vient gêner le démaillonnage ou l'évacuation des maillons. En effet lorsqu'un maillon reste solidaire du maillon suivant, ce dernier ne peut plus pivoter car sa capacité de pivotement se trouve réduite. Il en résulte une sortie des bandes non dissociées en maillons, ce qui provoque un freinage de la sortie de la bande conduisant à un blocage de l'arme.There is a significant risk of formation of a group of links that impede the unmaking or removal of the links. Indeed, when a link remains attached to the next link, the latter can not rotate because its ability to pivot is reduced. This results in an output of the non-dissociated bands in links, which causes a braking of the exit of the strip leading to a blockage of the weapon.

L'invention a pour but de proposer un dispositif de conception simple et peu encombrante qui permette de fiabiliser la séparation des maillons sortant en partie haute, donc qui sont entraînés naturellement par la gravité pour pivoter les uns par rapport aux autres.The object of the invention is to propose a device of simple and space-saving design which makes it possible to make reliable the separation of the links coming out at the top, which are naturally driven by the gravity to pivot relative to one another.

Ainsi, l'invention a pour objet un dispositif de séparation des maillons d'une bande d'emport de munitions, bande sortant d'une arme après tir au travers d'une ouverture de sortie et dans laquelle les maillons sont montés pivotant angulairement les uns par rapport aux autres, chaque maillon comportant deux étriers latéraux et un étrier médian, l'étrier médian du maillon (M1) pouvant pivoter dans des rainures des étriers latéraux du maillon suivant (M2), une position de pivotement relatif d'un premier maillon (M1) par rapport au maillon (M2) qui le suit permettant le décrochage du premier maillon, les maillons étant disposés par ailleurs relativement au dispositif dans une position telle que le pivotement assurant le déverrouillage et le décrochage du premier maillon peut se faire naturellement par l'action de la gravité s'exerçant sur le premier maillon, dispositif caractérisé en ce qu'il comporte des moyens assurant le basculement du premier maillon (M1) ainsi que des moyens assurant le guidage et le maintien du maillon suivant (M2) pendant le basculement du premier maillon (M1).Thus, the subject of the invention is a device for separating the links of an ammunition carrying strip, a strip coming out of a weapon after firing through an exit opening and in which the links are mounted to pivot angularly against the relative to each other, each link having two lateral stirrups and a median stirrup, the median stirrup of the link (M1) being pivotable in grooves of the lateral stirrups of the next link (M2), a relative pivoting position of a first link (M1) relative to the link (M2) that follows allowing the unhooking of the first link, the links being furthermore arranged relative to the device in a position such that the pivoting ensuring the unlocking and unhooking of the first link can be done naturally by the action of gravity exerted on the first link, characterized in that it comprises means ensuring the tilting of the first link (M1) and means for guiding and maintaining the next link (M2) during the tilting of the first link (M1).

Les moyens assurant le basculement pourront être constitués par au moins une lame élastique disposée au-dessus de l'ouverture de sortie de la bande, lame qui viendra en appui contre le corps du premier maillon lorsque le maillon suivant se trouvera maintenu par le moyen de guidage.The means ensuring the tilting may be constituted by at least one elastic blade disposed above the exit opening of the strip, which blade will bear against the body of the first link when the next link will be maintained by the guide means.

Les moyens assurant le basculement pourront ainsi être constitués par deux lames élastiques destinées chacune à coopérer avec un étrier latéral du premier maillon.The means ensuring the tilting may thus be constituted by two resilient blades each intended to cooperate with a lateral stirrup of the first link.

Par ailleurs, les moyens assurant le maintien et le guidage des maillons pourront être constitués par au moins deux ailettes sensiblement horizontales et coopérant avec des languettes solidaires du corps du maillon suivant.Furthermore, the means ensuring the maintenance and guidance of the links may be constituted by at least two substantially horizontal fins and cooperating with tabs secured to the body of the next link.

Les ailettes se prolongeront avantageusement vers l'intérieur de l'ouverture de façon à assurer le maintien de deux maillons consécutifs.The fins will advantageously extend towards the inside of the opening so as to ensure the maintenance of two consecutive links.

Le dispositif de séparation des maillons pourra aussi comporter un moyen de séparation constitué par au moins une lame rigide destinée à former une butée pour l'étrier médian du premier maillon.The device for separating the links may also include a separation means consisting of at least one rigid blade intended to form a stop for the median stirrup of the first link.

Avantageusement, le dispositif comportera un déflecteur disposé en dessous de l'ouverture de sortie.Advantageously, the device will comprise a deflector disposed below the outlet opening.

Le déflecteur pourra être constitué par une plaque solidaire d'un couloir de guidage des maillons.The deflector may be constituted by a plate secured to a guide corridor of the links.

L'invention sera mieux comprise à la lecture du descriptif qui va suivre en référence aux dessins annexés et dans lesquels :

  • les figures 1a et 1b montrent en perspective des maillons d'une bande de munitions que l'invention propose de séparer automatiquement,
  • la figure 2 est une vue en perspective montrant la sortie des bandes avec un mode de réalisation d'un dispositif de séparation selon l'invention,
  • les figures 3a, 3b, 3c et 3d montrent différentes phases successives du fonctionnement du dispositif selon invention.
The invention will be better understood on reading the description which will follow with reference to the appended drawings and in which:
  • the Figures 1a and 1b show in perspective links of a strip of ammunition that the invention proposes to separate automatically,
  • the figure 2 is a perspective view showing the exit of the strips with an embodiment of a separation device according to the invention,
  • the Figures 3a, 3b , 3c and 3d show different successive phases of the operation of the device according to the invention.

Les figures 1a et 1b ont été décrites dans le préambule de la présente demande. Elles ont uniquement pour objet de préciser la structure des maillons M1, M2 constitutifs d'une bande de munitions que l'invention cherche à dissocier.The Figures 1a and 1b have been described in the preamble of this application. Their only purpose is to specify the structure of links M1, M2 constituting a strip of ammunition that the invention seeks to dissociate.

La figure 2 montre un mode de réalisation d'un dispositif 5 de séparation des maillons M1, M2 d'une bande. On a représenté sur cette figure une paroi 6 solidaire de l'arme (non représentée) ou bien d'une tourelle. Une ouverture 7 est aménagée dans cette paroi pour permettre la sortie de la bande.The figure 2 shows an embodiment of a device 5 for separating the links M1, M2 of a band. This figure shows a wall 6 integral with the weapon (not shown) or a turret. An opening 7 is arranged in this wall to allow the exit of the strip.

On a représenté sur la figure 2 par les lettres H et B le haut (H) et le bas (B). On voit donc sur cette figure que les maillons M sortent de l'ouverture 7 orientés avec leurs étriers 2 ouverts vers le bas B. Dans cette orientation la force de gravité a pour effet de provoquer le pivotement naturel d'un premier maillon M1 par rapport au maillon suivant M2 lorsqu'il n'est plus maintenu. Par ailleurs suivant le montage d'arme mis en oeuvre ici ce sont les étriers latéraux 2 d'un maillon M qui sortent les premiers.We have shown on the figure 2 by the letters H and B the top (H) and the bottom (B). It can thus be seen in this figure that the links M exit from the opening 7 oriented with their stirrups 2 open towards the bottom B. In this orientation the force of gravity has the effect of causing the natural pivoting of a first link M1 relative to at the next link M2 when it is no longer maintained. Moreover, according to the weapon assembly used here, the lateral stirrups 2 of a link M come out first.

Le dispositif 5 selon l'invention comprend un support 8 qui est fixé par exemple par des vis 9 à la paroi 6. Ce support 8 porte deux lames élastiques 10 qui sont fixées au support 8 au-dessus de l'ouverture 7 de sortie de la bande. Ces lames élastiques sont réalisées en acier à ressort. Elles comportent une partie sensiblement horizontale 10a qui est prolongée par une partie inclinée 10b.The device 5 according to the invention comprises a support 8 which is fixed for example by screws 9 to the wall 6. This support 8 carries two resilient blades 10 which are fixed to the support 8 above the opening 7 of the outlet. the band. These resilient blades are made of spring steel. They comprise a substantially horizontal portion 10a which is extended by an inclined portion 10b.

Les lames 10a, 10b sont ici solidaires l'une de l'autre et réalisées par la découpe d'une feuille unique. Il serait bien entendu possible de prévoir deux lames distinctes.The blades 10a, 10b are here secured to one another and made by cutting a single sheet. It would of course be possible to provide two separate blades.

Les lames 10 sont destinées à venir en appui contre le corps du maillon M lors de sa sortie hors de l'ouverture 7 et plus particulièrement contre le profil externe des étriers latéraux 2 du maillon M.The blades 10 are intended to bear against the body of the link M when it leaves the opening 7 and more particularly against the outer profile of the side stirrups 2 of the link M.

Ainsi, chaque lame élastique 10 coopère avec un étrier latéral 2 du maillon.Thus, each elastic blade 10 cooperates with a lateral stirrup 2 of the link.

Le support 8 comporte également deux ailettes 11 sensiblement horizontales qui coopèrent avec des languettes 12 solidaires du corps du maillon (voir aussi les figures 1a et 1b qui montrent ces languettes). Les ailettes 11 assurent le maintien et le guidage des maillons M lors de leur sortie de l'ouverture 7.The support 8 also comprises two substantially horizontal fins 11 which cooperate with tabs 12 integral with the body of the link (see also FIGS. Figures 1a and 1b which show these tabs). The fins 11 maintain and guide the links M when they leave the opening 7.

Ces ailettes 11 sont fixées, par exemple par des vis 13, au niveau de prolongements latéraux 14 du support 8.These fins 11 are fixed, for example by screws 13, at lateral extensions 14 of the support 8.

Les lames élastiques 10 constituent des moyens qui assurent le basculement d'un premier maillon M1 sortant de l'ouverture 7. Par ailleurs les ailettes 11 constituent des moyens qui assurent le guidage et le maintien du maillon suivant M2 pendant le basculement du premier maillon M1.The resilient blades 10 constitute means which ensure the tilting of a first link M1 coming out of the opening 7. Furthermore the fins 11 constitute means which ensure the guidance and the maintenance of the following link M2 during the tilting of the first link M1 .

Le fait de maintenir un deuxième maillon pendant que l'on exerce sur les étriers latéraux du maillon précédant un couple de pivotement fiabilise la séparation des maillons quel que soit l'angle de pointage de l'arme. L'effort élastique exercé par les lames 10 complète en effet l'effet naturel de la gravité et permet de vaincre les frottements qui sont variables d'un maillon à l'autre.Holding a second link while exerting on the lateral brackets of the link preceding a pivoting torque makes reliable the separation of the links regardless of the angle of pointing of the weapon. The elastic force exerted by the blades 10 indeed completes the natural effect of gravity and overcomes the friction that is variable from one link to the other.

Le support 8 comporte enfin une lame rigide 15, disposée entre les lames élastiques 10, et qui est destinée à former une butée pour l'étrier médian du maillon 1. Cette lame en acier comporte elle aussi une partie inclinée. La valeur de l'angle d'inclinaison de cette lame est choisie en fonction des caractéristiques géométriques des maillons. Le but recherché est que l'étrier médian du maillon arrive en butée sur cette lame lorsqu'il a déjà pivoté par rapport aux étriers latéraux du maillon suivant. La lame 15 forme ainsi un moyen de séparation qui donne une impulsion fiabilisant la désolidarisation des maillons. On maîtrise ainsi l'instant de séparation des maillons qui suit le cycle de tir de l'arme.The support 8 finally comprises a rigid blade 15, disposed between the elastic blades 10, and which is intended to form a stop for the middle stirrup of the link 1. This steel blade also has an inclined portion. The value of the angle of inclination of this blade is chosen according to the geometrical characteristics of the links. The aim is that the median stirrup of the link reaches abutment on this blade when it has already pivoted relative to the side stirrups of the next link. The blade 15 thus forms a separation means which gives a reliable impulse the separation of the links. This controls the moment of separation of the links following the firing cycle of the weapon.

Le fonctionnement de l'invention va maintenant être décrit en référence aux figures 3a à 3d.The operation of the invention will now be described with reference to Figures 3a to 3d .

Ces figures sont très schématiques car elles ont pour simple objet d'expliciter le fonctionnement.These figures are very schematic because their only purpose is to explain the operation.

La figure 3a montre le dispositif seul avant la mise en place d'une bande de maillons. On a représenté également sur cette figure un couloir souple 16 qui permet de guider les bandes de maillons. Le couloir souple 16 porte des rails de guidage 19 sur lesquels glissent les languettes 12 des différents maillons. Le couloir 16 est relié à la paroi 6 au niveau de sa partie supérieure par une articulation 17. La partie basse du couloir 16 est libre et vient en appui sur la paroi 6.The figure 3a shows the device alone before setting up a band of links. There is also shown in this figure a flexible corridor 16 which guides the links strips. The flexible corridor 16 carries guide rails 19 on which slide the tongues 12 of the various links. The corridor 16 is connected to the wall 6 at its upper part by a hinge 17. lower part of the corridor 16 is free and bears on the wall 6.

Lors d'un changement d'alimentation le couloir 16 pivote sur l'articulation 17 et sa partie basse s'éloigne de la paroi 6.During a change of power the corridor 16 pivots on the articulation 17 and its lower part moves away from the wall 6.

Suivant une autre caractéristique de l'invention on a fixé un déflecteur 18 en dessous de l'ouverture de sortie 7. Ce déflecteur permet de guider les maillons dans leur chute et permet en particulier d'éviter que les maillons ne tombent sur le démaillonneur du couloir bas (lorsqu'on met en oeuvre une arme à double alimentation comme décrit dans le brevet FR-2849998 ).According to another characteristic of the invention, a deflector 18 has been fixed below the outlet opening 7. This deflector makes it possible to guide the links in their fall and, in particular, makes it possible to prevent the links from falling on the unblocker of the door. low corridor (when implementing a dual-feed weapon as described in the patent FR-2849998 ).

Ce déflecteur 18 pourrait être solidaire de la paroi 6. Il est cependant plus avantageux de le fixer au couloir 16 comme cela est représenté sur les figures. En effet dans ce cas (et toujours dans le cadre de la mise en oeuvre d'une arme à double alimentation), lorsque le couloir haut est inactif, la mécanique de l'arme commande le pivotement du couloir 16 vers l'intérieur de la tourelle. Le déflecteur 18 est alors lui aussi entraîné vers l'intérieur de la tourelle.This deflector 18 could be integral with the wall 6. It is however more advantageous to fix it to the corridor 16 as shown in the figures. Indeed in this case (and always in the context of the implementation of a double-feed weapon), when the high corridor is inactive, the mechanics of the weapon controls the pivoting of the corridor 16 towards the interior of the turret. The deflector 18 is then also driven towards the inside of the turret.

Ainsi, il ne risque pas de créer un obstacle pour les maillons notamment ceux provenant du couloir bas (non représenté). En effet ces derniers sont orientés avec leurs étriers ouverts vers le haut. Ils sont séparés à l'aide d'un dispositif démaillonneur distinct (et non décrit ici) qui les pousse vers le haut. Ces maillons risqueraient de rebondir sur le déflecteur 18 puis de revenir sur le démaillonneur bas entraînant un bourrage de maillons.Thus, it is not likely to create an obstacle for the links including those from the low corridor (not shown). Indeed these are oriented with their stirrups open up. They are separated using a separate unmounting device (not described here) that pushes them upward. These links could bounce on the deflector 18 and then return to the bottom unstacker causing a link jam.

On a représenté sur la figure 3b une bande de maillons M qui sort de l'ouverture 7 suivant la direction S.We have shown on the figure 3b a band of links M which leaves the opening 7 in the direction S.

Les étriers latéraux 2 du premier maillon M1 viennent en contact avec les parties inclinées 10b des lames élastiques 10.The lateral stirrups 2 of the first link M1 come into contact with the inclined portions 10b of the elastic blades 10.

Ces dernières se déforment ce qui a pour effet de créer une force F qui s'exerce sur les étriers latéraux 2 du premier maillon M1. Dans le même temps le maillon suivant M2 se trouve maintenu par les ailettes 11 qui soutiennent ses languettes 12. Le maillon M2 étant maintenu, la force F crée un couple qui assure le pivotement fiable du maillon M1 par rapport au maillon M2 quels que soient les frottements.The latter are deformed which has the effect of creating a force F which is exerted on the side stirrups 2 of the first link M1. At the same time the following link M2 is held by the fins 11 which support its tongues 12. The link M2 being maintained, the force F creates a torque which ensures the reliable pivoting of the link M1 with respect to the link M2 whatever the friction.

Par ailleurs le maillon M1 est supporté par les ailettes de guidage 11 jusqu'à ce que ses étriers latéraux arrivent sur les lames 10. L'espace entre la fin des ailettes de guidage 11 et les lames élastiques 10 correspond donc sensiblement à la longueur des languettes 12.Moreover, the link M1 is supported by the guide vanes 11 until its lateral stirrups arrive on the blades 10. The space between the end of the guide vanes 11 and the elastic blades 10 therefore corresponds substantially to the length of the blades. tabs 12.

Comme on le voit sur les figures 3a à 3d, les ailettes 11 s'étendent longitudinalement vers l'intérieur de l'ouverture 7 pour prendre le relais des rails de guidage 19 du couloir à maillons 16 et comportent ainsi une partie arrière 11a qui s'engage en dessous des languettes 12 du troisième maillon M3. On assure ainsi constamment un guidage d'au moins deux maillons M consécutifs au niveau de l'ouverture 7. Ceci augmente la rigidité du maintien et assure un guidage fiable de la sortie des maillons.As we see on the Figures 3a to 3d , the fins 11 extend longitudinally inwardly of the opening 7 to take over the guide rails 19 of the link corridor 16 and thus comprise a rear portion 11a which engages below the tongues 12 of the third link M3. This ensures constantly guiding at least two consecutive links M at the opening 7. This increases the rigidity of the maintenance and ensures reliable guidance of the output of the links.

La longueur des ailettes 11 est aussi telle qu'à l'arrêt du tir, les languettes 12 du premier maillon sont encore au moins partiellement en appui sur les ailettes 11.The length of the fins 11 is also such that, when the shot is stopped, the tabs 12 of the first link are at least partially resting on the fins 11.

Dans le cas de couloirs sans rails de guidage 19, couloirs dans lesquels les maillons sont guidés par la structure même du couloir, on pourra adapter la forme d'extrémité des ailettes 11 pour assurer une continuité du guidage des maillons entre le couloir et le dispositif de démaillonnage.In the case of corridors without guide rails 19, corridors in which the links are guided by the structure of the corridor, we can adapt the end shape of the fins 11 to ensure continuity of the guide links between the corridor and the device unmaking.

On a représenté sur la figure 3c le maillon M1 presque totalement pivoté. L'étrier médian 1 du maillon M1 arrive en contact avec la lame rigide 15 alors que les étriers latéraux 2 du maillon M2 sont toujours maintenus par les ailettes 11.We have shown on the figure 3c the link M1 almost completely rotated. The median stirrup 1 of the link M1 comes into contact with the rigid blade 15 while the lateral stirrups 2 of the link M2 are still held by the fins 11.

La lame rigide 15 donne une impulsion qui provoque la séparation du maillon M1 qui chute alors hors de la tourelle (figure 3d). Le cycle de démaillonnage se poursuit ensuite d'une façon identique avec les autres maillons.The rigid blade 15 gives a pulse which causes the separation of the link M1 which then falls out of the turret ( figure 3d ). The destacking cycle then continues in the same way with the other links.
