Abstract

The device has a transfer unit driving ammunition bands (9) from ammunition cases to a weapon pivotably mounted on trunnions, where the unit has a rigid channel (10). The unit has a guide (11) pivotably mounted around an axle merged with an axis (2) of the trunnions of the weapon. A ball pivot (15) slightly displaces the channel with respect to the guide, during the pivoting of the guide. A mounting clearance is formed between the channel and the weapon.

Description

Le domaine technique de l'invention est celui des dispositifs d'alimentation d'une arme en munitions solidaires de maillons.The technical field of the invention is that of feeding devices of a munitions weapon secured to links.

De tels dispositifs sont bien connus et ils comportent généralement un ou plusieurs couloirs d'alimentation conduisant les munitions d'une caisse de stockage à l'arme.Such devices are well known and generally include one or more feed corridors driving ammunition from a storage crate to the weapon.

Les armes sont le plus souvent solidaires d'un affût qui permet un pointage de l'arme en site (basculement par rapport à un axe horizontal) et un pointage en gisement (pivotement autour d'un axe vertical).The weapons are most often attached to a lookout which allows a pointing of the weapon in site (tilting with respect to a horizontal axis) and a pointing in bearing (pivoting around a vertical axis).

Un des problèmes rencontrés avec les dispositifs d'alimentation connus est celui de permettre l'alimentation de l'arme quel que soit l'angle de site ou de gisement de celle ci.One of the problems with known feeders is that of allowing the supply of the weapon regardless of the angle of the site or deposit thereof.

Par ailleurs les dispositifs d'alimentation doivent aussi suivre le recul de l'arme lors du tir.In addition, the feeding devices must also follow the recoil of the weapon when firing.

On met en oeuvre habituellement des couloirs articulés qui sont composés de nombreuses pièces permettant d'accompagner les différents mouvements de l'arme.Articulated corridors are usually used which are composed of numerous parts allowing to accompany the different movements of the weapon.

Ces solutions sont complexes et coûteuses à mettre en oeuvre.These solutions are complex and expensive to implement.

Le brevet US-5299487 , qui représente le point de départ pour le préambule de la revendication 1, montre un système d'arme comportant un couloir télescopique entourant en partie l'axe des tourillons. Une telle solution est elle aussi complexe et peut conduire à des efforts de traction excessifs sur les bandes de munitions.The patent US 5299487 , which represents the starting point for the preamble of claim 1, shows a weapon system comprising a telescopic corridor partially surrounding the axis of the trunnions. Such a solution is also complex and can lead to excessive tensile forces on the ammunition strips.

C'est le but de l'invention que de proposer un dispositif d'alimentation permettant de pallier de tels inconvénients.It is the object of the invention to provide a feed device for overcoming such disadvantages.

Ainsi le dispositif selon invention permet d'assurer avec des moyens simples et rustiques l'alimentation de l'arme quel que soit son positionnement en site et/ou en gisement et quelle que soit sa position de recul.Thus, the device according to the invention makes it possible to provide, with simple and rustic means, the supply of the weapon irrespective of its positioning in the site and / or in the field and whatever its position of recoil.

Ainsi l'invention a pour objet un dispositif d'alimentation d'une arme en munitions solidaires de maillons et à partir d'au moins une caisse à munitions, dispositif comprenant au moins un moyen de transfert conduisant les munitions de la caisse à l'arme qui est montée pivotante sur des tourillons, moyen de transfert comprenant au moins un couloir, dispositif caractérisé en ce que le moyen de transfert comprend également un guide comprenant une entrée disposée au-dessus de la ou des caisses et une sortie orientée sensiblement suivant une direction parallèle ou voisine de l'axe de recul de l'arme, guide monté pivotant autour d'un axe confondu avec l'axe des tourillons de l'arme, l'entrée du guide étant délimitée en partie par un galet cylindrique disposé autour de l'axe de pivotement.Thus, the subject of the invention is a device for feeding an ammunition weapon secured to links and from at least one ammunition case, a device comprising at least one transfer means driving the ammunition of the body to the ammunition case. weapon which is pivotally mounted on journals, transfer means comprising at least one corridor, device characterized in that the transfer means also comprises a guide comprising an inlet disposed above the crate or crates and an outlet oriented substantially in a direction parallel or close to the axis of recoil of the weapon, guide pivoted about an axis coincident with the axis of the trunnions of the weapon, the inlet of the guide being delimited in part by a cylindrical roller disposed about the pivot axis.

Le guide pourra également comporter un autre galet monté rotatif sur le guide, les deux galets délimitant ainsi l'entrée du guide.The guide may also include another roller rotatably mounted on the guide, the two rollers thus delimiting the entrance of the guide.

Selon une caractéristique de l'invention, le guide pourra comporter au moins une roue d'entraînement des maillons, roue solidaire d'un moyen commandant sa rotation.According to one characteristic of the invention, the guide may comprise at least one drive wheel links, wheel integral with a means controlling its rotation.

Le moyen commandant la rotation de la roue d'entraînement pourra être une manivelle.The means controlling the rotation of the drive wheel may be a crank.

La roue d'entraînement pourra avantageusement être associée à un moyen de verrouillage anti retour.The drive wheel may advantageously be associated with an anti-return locking means.

Le moyen de verrouillage anti retour pourra comporter une dent pivotante qui s'engagera sur des dentures solidaires de la roue d'entraînement, dent maintenue appliquée contre les dentures par un moyen ressort.The anti-return locking means may comprise a pivoting tooth which will engage on teeth secured to the drive wheel, tooth maintained pressed against the teeth by a spring means.

La dent pourra être maintenue à distance de la roue d'entraînement par une béquille.The tooth can be kept away from the drive wheel by a crutch.

Selon un premier mode de réalisation de l'invention, le moyen de transfert pourra comprendre également un couloir rigide qui sera fixé au niveau de la sortie du guide par un moyen rotule et qui sera relié à l'arme avec jeu au niveau d'une glissière fixe, le jeu, l'angle de pivotement du guide ainsi que la rotule étant définis pour autoriser le mouvement de recul de l'arme.According to a first embodiment of the invention, the transfer means may also comprise a rigid corridor which will be fixed at the outlet of the guide by a ball joint means and which will be connected to the weapon with clearance at a fixed slide, the game, the pivot angle of the guide and the ball joint being defined to allow the recoil movement of the weapon.

Selon un deuxième mode de réalisation, le moyen de transfert pourra comprendre un couloir rigide qui est solidaire du guide, couloir qui coiffe une ouverture d'introduction de munitions dans l'arme, et dont la largeur est suffisante pour autoriser le mouvement de recul de l'arme par rapport au couloir.According to a second embodiment, the transfer means may comprise a rigid corridor which is integral with the guide, a corridor which covers an opening for introducing ammunition into the weapon, and whose width is sufficient to allow the recoil movement to the weapon in relation to the corridor.

Dans tous les cas, le couloir rigide comprendra une lame suivant le profil du couloir de son entrée à sa sortie et assurant une butée de positionnement pour les maillons lors de leur progression dans le couloir.In all cases, the rigid corridor will include a blade following the profile of the corridor from its entrance to its exit and providing a positioning stop for the links during their progression in the corridor.

Le dispositif pourra enfin comporter un entonnoir d'introduction solidaire de la partie reculante de l'arme, entonnoir comprenant une languette arrière recevant le culot des munitions et un doigt avant sur lequel viennent en appui les maillons, le doigt avant se trouvant sensiblement dans le prolongement de la lame de guidage du couloir lorsque l'arme est en position de repos avant tir.The device may finally comprise an insertion funnel integral with the retreating part of the weapon, funnel comprising a rear tongue receiving the base of the ammunition and a front finger on which abut the links, the front finger being substantially in the extension of the corridor guide blade when the weapon is in the rest position before firing.

En se reportant aux figures 1 et 2, une arme 1 est montée pivotante sur des tourillons par rapport à un affût 3 formé d'une fourche, elle-même pivotante autour d'un axe 4 vertical par rapport à un socle 5. L'axe 2 des tourillons est représenté en pointillés sur la figure.Referring to figures 1 and 2 , a weapon 1 is pivotally mounted on journals with respect to a carriage 3 formed of a fork, itself pivoting about a vertical axis 4 relative to a base 5. The axis 2 of the pins is shown in dotted lines on the face.

L'arme 1 ne fait pas l'objet de la présente invention et ne sera donc pas décrite en détail. Elle est ici équipée d'un viseur optronique 6.The weapon 1 is not the subject of the present invention and will not be described in detail. It is here equipped with an optronic viewfinder 6.

Cette arme 1 est une arme de moyen calibre (calibre inférieur ou égal à 50 mm). Elle est alimentée par des bandes de munitions. Une bande de munitions comprend des maillons qui maintiennent chacun une munition, les maillons sont liés les uns aux autres de façon articulée. Il est classique de rendre ainsi des munitions de petit ou moyen calibre solidaires de maillons pour faciliter l'alimentation de l'arme. Cette dernière comprend alors un moyen de démaillonage (non représenté) qui permet de désolidariser à l'entrée de l'arme les munitions d'avec les maillons.This weapon 1 is a medium caliber weapon (caliber less than or equal to 50 mm). It is fed by ammunition strips. An ammunition strip includes links that each hold a munition, the links are hinged to each other. It is conventional to make ammunition of small or medium caliber solidarity links to facilitate the supply of the weapon. The latter then comprises a means of demaillonage (not shown) which allows to separate at the entrance of the weapon ammunition with the links.

Les munitions sont disposées dans deux caisses 7a et 7b placées côte à côte et solidaires d'une paroi latérale 8 de l'affût 3. Chaque caisse renferme une bande de munitions 9 et les deux bandes sont liées l'une à l'autre entre chaque caisse.The ammunition is arranged in two boxes 7a and 7b placed side by side and integral with a side wall 8 of the carriage 3. Each box contains a band of ammunition 9 and the two bands are linked to each other between each case.

A cet effet, les munitions sont disposées dans la caisse 7b de telle sorte que le premier maillon de la bande soit placé au niveau d'un premier bord latéral supérieur de la caisse 7b alors que le dernier maillon de la bande est disposé au niveau de l'autre bord latéral supérieur de cette caisse.For this purpose, the ammunition is disposed in the box 7b so that the first link of the band is placed at a first upper lateral edge of the box 7b while the last link of the strip is disposed at the other side of the upper side of the box.

Il est ainsi possible de raccorder le dernier maillon de la bande de la caisse 7a avec le premier maillon de la bande de la caisse 7b (voir figure 3 - repère L montrant la liaison entre les bandes).It is thus possible to connect the last link of the strip of the box 7a with the first link of the strip of the box 7b (see figure 3 - mark L showing the connection between the bands).

Ce raccordement est réalisé d'une façon classique à l'aide d'un outil approprié. Ainsi après mise en place sur l'arme des deux caisses 7a et 7b, les deux bandes de chaque caisse ne forment plus qu'une seule bande continue de munitions 9 réparties entre les deux caisses 7a et 7b.This connection is made in a conventional manner using a suitable tool. Thus, after placing the two boxes 7a and 7b on the weapon, the two strips of each box form a single continuous band of ammunition 9 distributed between the two boxes 7a and 7b.

Le dispositif d'alimentation selon un premier mode de réalisation de l'invention comprend au moins un moyen de transfert conduisant les munitions 9 de la caisse 7a ou 7b à l'arme 1 montée pivotante sur ses tourillons.The feed device according to a first embodiment of the invention comprises at least one transfer means driving the ammunition 9 of the box 7a or 7b to the weapon 1 pivotally mounted on its trunnions.

Ce moyen de transfert comprend au moins un couloir 10 ainsi qu'un guide 11 qui comprend une entrée 11a disposée au-dessus des caisses 7a, 7b et une sortie 11b orientée sensiblement suivant une direction parallèle ou voisine de celle de l'axe de recul R de l'arme 1 (voir également la figure 3):This transfer means comprises at least one corridor 10 and a guide 11 which comprises an inlet 11a disposed above the boxes 7a, 7b and an outlet 11b oriented substantially in a direction parallel to or close to that of the recoil axis R of the weapon 1 (see also figure 3 ):

Conformément à une caractéristique essentielle de l'invention, le guide 11 est monté pivotant autour d'un axe 12 qui est confondu avec l'axe 2 des tourillons de l'arme 1.According to an essential characteristic of the invention, the guide 11 is pivotally mounted about an axis 12 which coincides with the axis 2 of the journals of the weapon 1.

La position de l'axe 2 a été repérée sur la figure 3. La figure 6 montre plus précisément le mode de fixation de l'axe 12 au niveau d'un tourillon 36 de l'arme. Cet axe autour duquel bascule le guide 11 est solidaire d'une cage 13 vissée à la paroi 8 de l'affût 3. La cage 13 permet de positionner l'axe 12 dans le prolongement de l'axe 2 des tourillons.The position of axis 2 has been identified on the figure 3 . The figure 6 shows more precisely the mode of attachment of the axis 12 at a trunnion 36 of the weapon. This axis around which tilts the guide 11 is secured to a cage 13 screwed to the wall 8 of the carriage 3. The cage 13 is used to position the axis 12 in the extension of the axis 2 of the journals.

La cage 13 porte également un galet 14 cylindrique rotatif qui assure un guidage des bandes de munitions.The cage 13 also carries a rotating cylindrical roller 14 which guards the ammunition strips.

Le couloir 10 du moyen de transfert est ici un couloir rigide qui est fixé au niveau de la sortie 11b du guide 11 par un moyen rotule 15 (représenté schématiquement sur les figures). Ce moyen rotule est conçu de façon à autoriser un léger débattement angulaire du couloir 10 par rapport au guide 11, débattement autour d'un axe 16 perpendiculaire au plan de la figure 3 et disposé sensiblement au niveau de la jonction entre le rebord supérieur de la sortie 11b du guide 11 et le rebord supérieur du couloir 10.The corridor 10 of the transfer means is here a rigid corridor which is fixed at the outlet 11b of the guide 11 by a ball joint means 15 (shown schematically in the figures). This ball joint means is designed to allow a slight angular displacement of the passage 10 relative to the guide 11, deflection about an axis 16 perpendicular to the plane of the figure 3 and disposed substantially at the junction between the upper rim of the outlet 11b of the guide 11 and the upper rim of the passageway 10.

La flèche P sur la figure 3 schématise ce débattement.The arrow P on the figure 3 schematizes this movement.

Le couloir 10 est fixé sur l'arme par des moyens (non représentés, tels que des vis). Le couloir coiffe ainsi une ouverture d'introduction des munitions dans l'arme. Il est classique de réaliser ainsi une telle liaison d'un couloir souple sur une arme. Avec ce mode de réalisation de l'invention le couloir n'est pas souple mais rigide et on donnera à la liaison couloir/arme un léger jeu (de l'ordre de 1 mm) qui permettra de compenser les désalignements qui n'auront pas pu être absorbés par le pivotement du guide 11 et par la rotule 15.The corridor 10 is fixed on the weapon by means (not shown, such as screws). The corridor thus caps an opening for introducing ammunition into the weapon. It is conventional to thus achieve such a connection of a flexible corridor on a weapon. With this embodiment of the invention the corridor is not flexible but rigid and will give the link corridor / weapon a slight clearance (of the order of 1 mm) which will compensate for misalignments that will not could be absorbed by the pivoting of the guide 11 and by the patella 15.

Les figures 4a à 4d montrent plus précisément la structure du guide 11.The Figures 4a to 4d show more precisely the structure of the guide 11.

Celui ci est un boîtier en tôle pliée comportant une paroi externe 11c et des joues latérales (seule la joue avant 11d est visible sur les figures). La partie inférieure du guide 11 reçoit l'axe de pivotement 12. On voit sur les figures qu'un galet cylindrique 17 rotatif est disposé autour de cet axe 12 pour assurer un guidage des bandes de munitions 9. Un autre galet 18 est également monté rotatif sur le boîtier. Les deux galets 17 et 18 délimitent l'entrée 11a du guide 11.This is a folded sheet metal casing having an outer wall 11c and side cheeks (only the front cheek 11d is visible in the figures). The lower part of the guide 11 receives the pivot axis 12. It can be seen in the figures that a rotating cylindrical roller 17 is arranged around this axis 12 to provide guidance for the ammunition strips 9. Another roller 18 is also mounted rotating on the housing. The two rollers 17 and 18 define the inlet 11a of the guide 11.

Le guide 11 comporte également une roue 19 d'entraînement des maillons. De telles roues sont classiques dans les dispositifs d'entraînement de munitions en bandes. Elles comportent différents bras délimitant des alvéoles recevant les munitions 9 (ici une seule munition est représentée avec un seul maillon). La roue 19 est solidaire d'un moyen 20 permettant de commander sa rotation.The guide 11 also comprises a wheel 19 for driving the links. Such wheels are conventional in strip ammunition training devices. They comprise different arms delimiting cells receiving ammunition 9 (here only one ammunition is represented with a single link). The wheel 19 is secured to a means 20 for controlling its rotation.

Ce moyen 20 est constitué par une manivelle qui entraîne directement l'axe de la roue 19.This means 20 is constituted by a crank which directly drives the axis of the wheel 19.

La roue d'entraînement 19 est par ailleurs associée à un moyen 21 assurant un verrouillage anti retour de la roue 19.The drive wheel 19 is also associated with a means 21 providing an anti-return lock of the wheel 19.

Ce moyen de verrouillage anti retour comporte une dent 22 qui est pivotante sur un axe 23 et qui s'engage sur des dentures 24 solidaires de la roue d'entraînement 19.This anti-return locking means comprises a tooth 22 which is pivotable on an axis 23 and which engages teeth 24 secured to the drive wheel 19.

La dent 22 est maintenue appliquée contre les dentures 24 par un moyen ressort 25 (représenté schématiquement sur les figures 4c et 4d).The tooth 22 is held against the teeth 24 by a spring means 25 (shown schematically on the Figures 4c and 4d ).

Par ailleurs la dent 22 peut être maintenue à distance de la roue d'entraînement 19 par une béquille 26 articulée sur un axe 27.Furthermore, the tooth 22 can be kept at a distance from the drive wheel 19 by a stand 26 articulated on an axis 27.

Le fonctionnement du guide 11 est le suivant.The operation of the guide 11 is as follows.

Les munitions 9 en bandes provenant d'une caisse 7a ou 7b sont introduites dans le guide par l'entrée 11a. Lorsque la première munition est positionnée dans une des alvéoles de la roue 19 on actionne la manivelle 20. La roue 19 tourne et la bande de munitions est entraînée et peut suivre le guide 11 puis le couloir 10 jusqu'à l'arme. Le chargement initial de celle ci se trouve donc facilité. Il n'est pas nécessaire de démonter le couloir 10 et le guide 11 pour pouvoir amener une bande de munitions jusqu'à l'arme.The ammunition 9 in strips from a box 7a or 7b are introduced into the guide by the inlet 11a. When the first munition is positioned in one of the cells of the wheel 19 is actuated the crank 20. The wheel 19 rotates and the ammunition strip is driven and can follow the guide 11 and the corridor 10 to the weapon. The initial loading of this one is thus facilitated. It is not necessary to disassemble the corridor 10 and the guide 11 to be able to bring a band of ammunition to the weapon.

Le moyen de verrouillage anti retour 21 sécurise l'opération d'alimentation. En effet le mouvement de la roue 19 n'est possible que dans un seul sens. Si on stoppe ou relâche la manivelle 20, la masse de la bande de munition ne peut pas entraîner celle ci en arrière.The anti-return locking means 21 secures the feeding operation. Indeed the movement of the wheel 19 is only possible in one direction. If we stop or release the crank 20, the mass of the ammunition strip can not drive it back.

Lorsqu'on souhaite au contraire retirer une bande de munitions engagée dans une arme, il suffit de basculer avec le doigt le moyen anti retour 21 contre l'action du ressort de rappel 25 (flèche B sur la figure 4c). On peut ainsi dégager la dent 23 de la denture 24 de la roue 19. On positionne alors la béquille 26 dans une encoche de la dent 22 ce qui empêche sont retour vers la roue 19. La roue 19 est alors totalement débrayée et il devient possible de la faire tourner dans les deux sens.When, on the contrary, it is desired to remove a strip of ammunition engaged in a weapon, it suffices to tip the anti-return means 21 against the action of the return spring 25 (arrow B on the figure 4c ). It is thus possible to disengage the tooth 23 from the toothing 24 of the wheel 19. The jack 26 is then positioned in a notch of the tooth 22, which prevents its return to the wheel 19. The wheel 19 is then completely disengaged and it becomes possible to turn it in both directions.

On basculera ensuite la béquille 26 pour remettre en place le moyen anti retour 21.The stand 26 will then be tilted to replace the anti-return means 21.

Comme cela est plus particulièrement visible sur la figure 5, le couloir rigide 10 est formé d'une tôle pliée qui délimite un couloir de passage pour la bande de munitions 9.As this is particularly visible on the figure 5 , the rigid corridor 10 is formed of a folded sheet which delimits a passage corridor for the ammunition strip 9.

Le couloir 10 est fermé par un couvercle qui est retiré sur ces figures. La figure 5 montre également partiellement le guide 11 avec la tôle 11c retirée (la rotule 15 n'est pas représentée sur cette figure). On voit sur cette figure que le couloir 10 et le guide 11 comportent chacun une lame 29 ou 28 qui est fixée sur la tôle de fond du guide ou du couloir.The corridor 10 is closed by a cover which is removed in these figures. The figure 5 also partially shows the guide 11 with the sheet 11c removed (the ball joint 15 is not shown in this figure). It can be seen in this figure that the corridor 10 and the guide 11 each comprise a blade 29 or 28 which is fixed on the bottom plate of the guide or the corridor.

Ces lames sont dans le prolongement l'une de l'autre et elles suivent chacune le profil du guide et du couloir.These blades are in the extension of each other and they follow each the profile of the guide and the corridor.

Elles ont pour fonction d'assurer une butée de positionnement pour les maillons lors de leur progression dans le couloir 10 et le guide 11.Their function is to ensure a positioning stop for the links during their progression in the corridor 10 and the guide 11.

On a représenté ainsi sur la figure 5 un maillon 30 portant une munition 9. Le maillon est en contact avec la lame 29 et la munition est en contact avec une tôle latérale du couloir 10. Le guidage de la bande de munitions est ainsi parfaitement assuré le long de la courbure du couloir 10.This is represented on the figure 5 a link 30 carrying a munition 9. The link is in contact with the blade 29 and the munition is in contact with a side plate of the corridor 10. The guidance of the ammunition strip is thus perfectly ensured along the curvature of the corridor 10 .

Le fonctionnement de ce premier mode de réalisation du dispositif d'alimentation au cours du tir va maintenant être décrit en référence aux figures 7a à 7c.The operation of this first embodiment of the feeding device during shooting will now be described with reference to Figures 7a to 7c .

Avant tir l'arme et son système d'alimentation se trouvent dans les positions représentées à la figure 7a. Lors du tir l'arme 1 recule (flèche R), la position de recul maximal est représentée à la figure 7b.Before firing the weapon and its power system are in the positions represented in the figure 7a . When firing the weapon 1 moves back (arrow R), the maximum recoil position is represented at the figure 7b .

Le mouvement de recul R entraîne une traction de la bande de munitions qui se communique au guide 11. Ce dernier pivote alors autour de son axe 12 (figure 7b - flèche P1). L'amplitude du pivotement reste la même quel que soit l'angle de site car l'axe 12 de pivotement du guide est confondu avec l'axe 2 des tourillons.The recoil movement R causes a pull of the ammunition strip that communicates with the guide 11. The latter then pivots about its axis 12 ( figure 7b - arrow P1). The amplitude of the pivot remains the same regardless of the elevation angle because the axis 12 of pivoting of the guide coincides with the axis 2 of the journals.

Lors du pivotement du guide la rotule 15 autorise le débattement du couloir rigide 10 par rapport au guide 11 (flèche P2).During pivoting of the guide, the ball joint 15 allows the clearance of the rigid passage 10 with respect to the guide 11 (arrow P2).

Le jeu de montage entre le couloir rigide et l'arme va absorber les désalignements résiduels entre le couloir et l'arme. Dans tous les cas les munitions restent guidées par la lame 29 dans le couloir 10.The mounting clearance between the rigid corridor and the weapon will absorb residual misalignments between the corridor and the weapon. In all cases the ammunition remains guided by the blade 29 in the corridor 10.

Bien entendu l'Homme du Métier définira le dispositif d'alimentation de telle sorte que l'angle de pivotement du guide, le jeu de montage couloir/arme ainsi que le débattement autorisé par la rotule sont suffisants pour autoriser le mouvement de recul de l'arme.Of course the skilled person will define the feeding device so that the pivot angle of the guide, the mounting kit corridor / weapon and the clearance authorized by the patella are sufficient to allow the recoil of the weapon.

Après le recul maximal, l'arme 1 revient en batterie (flèche CR), la position de contre recul maximal est représentée à la figure 7c.After the maximum recoil, the weapon 1 comes back in battery (arrow CR), the position of maximum recoil is represented at the Figure 7c .

Le mouvement de contre recul CR provoque via la bande de munitions un basculement du guide 11 autour de son axe 12 dans un sens inverse à celui observé lors du recul (figure 7c - flèche P3). Là encore l'amplitude du pivotement reste la même quel que soit l'angle de site car l'axe 12 de pivotement du guide est confondu avec l'axe 2 des tourillons.The recoil movement CR causes via the ammunition strip a tilting of the guide 11 around its axis 12 in a direction opposite to that observed during the recoil ( Figure 7c - arrow P3). Again the amplitude of the pivot remains the same regardless of the elevation angle because the pivot axis 12 of the guide coincides with the axis 2 of the journals.

Lors de ce pivotement du guide la rotule 15 autorise encore un léger débattement du couloir rigide 10 par rapport au guide 11 (flèche P4).During this pivoting of the guide the patella 15 still allows a slight movement of the rigid passage 10 relative to the guide 11 (arrow P4).

Là encore, le jeu de montage entre le couloir rigide et l'arme absorbera les désalignements résiduels entre le couloir et l'arme. Dans tous les cas les munitions restent guidées par la lame 29 dans le couloir 10.Again, the mounting clearance between the rigid corridor and the weapon will absorb residual misalignments between the corridor and the weapon. In all cases the ammunition remains guided by the blade 29 in the corridor 10.

On voit que le dispositif d'alimentation selon ce mode de réalisation de l'invention permet d'assurer l'alimentation en munitions d'une arme à l'aide d'un couloir rigide. La fabrication est donc très simplifiée et le coût est réduit.It can be seen that the feed device according to this embodiment of the invention makes it possible to ensure the supply of ammunition of a weapon using a rigid corridor. Manufacturing is therefore very simplified and the cost is reduced.

Il est cependant possible d'associer le guide pivotant selon l'invention avec un couloir souple de type connu. L'avantage qui en résulte est une limitation de la déformation du couloir lors du fonctionnement de l'arme car le recul est pris par la rotation.It is however possible to associate the pivoting guide according to the invention with a flexible corridor of known type. The advantage that results is a limitation of the deformation of the corridor during the operation of the weapon because the recoil is taken by the rotation.

Par ailleurs le moyen d'entraînement incorporé au guide 11 permet d'assurer la conduite de la bande de munitions jusqu'à l'arme sans qu'il soit nécessaire de démonter les couloirs d'alimentation.Furthermore, the drive means incorporated in the guide 11 makes it possible to drive the ammunition strip to the weapon without the need to dismantle the feed passages.

Les figures 8, 9a, 9b, 9c et 10 montrent un deuxième mode de réalisation de l'invention. Ce mode diffère du précédent en ce que le guide 11 et le couloir rigide 10 forment une seule et même pièce rigide 110 en tôle pliée et soudée.The figures 8 , 9a , 9b , 9c and 10 show a second embodiment of the invention. This mode differs from the previous one in that the guide 11 and the rigid passage 10 form a single rigid piece 110 folded and welded sheet.

D'une façon analogue à la figure 5, la figure 8 montre ainsi l'ensemble guide/couloir 110 couvercle retiré.In a similar way to figure 5 , the figure 8 thus shows the entire guide / corridor 110 cover removed.

On voit que ce guide /couloir comporte une lame 29 unique qui est fixée sur la tôle de fond et qui permet d'assurer une butée de positionnement pour les maillons lors de leur progression dans le guide/couloir.We see that this guide / corridor has a single blade 29 which is fixed on the bottom plate and which ensures a positioning stop for the links during their progression in the guide / corridor.

Tout le descriptif précédent relatif à la structure des moyens d'entraînement des munitions à l'intérieur du guide reste valable pour ce mode de réalisation (description des figures 4a à 4d).All the preceding description relating to the structure of the ammunition drive means within the guide remains valid for this embodiment (description of the Figures 4a to 4d ).

Comme cela est plus particulièrement visible à la figure 9a, le guide/couloir rigide 110 comporte une extrémité évasée qui vient coiffer l'arme 1 au niveau d'une ouverture 31 permettant l'introduction des munitions dans celle ci. Cette extrémité du couloir n'est pas solidaire de l'arme qui peut donc librement coulisser par rapport au couloir.As this is particularly visible in the figure 9a , the rigid guide / corridor 110 has a flared end which caps the weapon 1 at an opening 31 for the introduction of the ammunition therein. This end of the corridor is not secured to the weapon which can therefore freely slide relative to the corridor.

Afin de fiabiliser l'introduction des munitions dans l'arme, cette dernière comporte au niveau de l'ouverture 31 un entonnoir d'introduction 34 qui comprend une languette arrière 32 recevant le culot des munitions 9 et un doigt avant 33 sur lequel viennent en appui les maillons. L'entonnoir 34 est fixé à l'arme par des verrous d'attache rapide 35 (voir figure 10).In order to make the introduction of the ammunition into the weapon more reliable, the latter comprises, at the level of the opening 31, an introductory funnel 34 which comprises a rear tongue 32 receiving the base of the ammunition 9 and a front finger 33 on which come support the links. The funnel 34 is attached to the weapon by quick-release locks 35 (see FIG. figure 10 ).

L'entonnoir 34 est défini de telle sorte que le doigt avant 33 se trouve sensiblement dans le prolongement de la lame de guidage 28 du couloir 110 lorsque l'arme est en position de repos avant tir (figure 9a).The funnel 34 is defined so that the front finger 33 is substantially in the extension of the guide blade 28 of the lane 110 when the weapon is in the rest position before firing ( figure 9a ).

Ainsi les munitions se trouvent amenées progressivement du couloir rigide à l'ouverture 31. Le fonctionnement de ce mode de réalisation au cours du tir va maintenant être décrit en référence aux figures 9a à 9c.Thus the ammunition is brought gradually from the rigid corridor to the opening 31. The operation of this embodiment during the firing will now be described with reference to Figures 9a to 9c .

Avant tir l'arme et son système d'alimentation se trouvent dans les positions représentées à la figure 9a. Lors du tir l'arme 1 recule (flèche R), la position de recul maximal est représentée à la figure 9b.Before firing the weapon and its power system are in the positions represented in the figure 9a . When firing the weapon 1 moves back (arrow R), the maximum recoil position is represented at the figure 9b .

Le mouvement de recul R entraîne une traction de la bande de munitions qui peut de déplacer de façon libre dans l'extrémité évasée du guide/couloir 110. Il n'y a pas ici comme dans le mode de réalisation précédent de pivotement du guide 110 autour de son axe 12.The recoil movement R causes a pull of the ammunition strip which can move freely in the flared end of the guide / corridor 110. There is not here as in the previous embodiment of pivoting guide 110 around its axis 12.

La capacité de pivotement du guide 110 permet néanmoins d'accompagner le pivotement en site de l'arme sur ses tourillons. Ce mouvement se fait sans blocage ni déformation du couloir/guide 110 car l'axe 12 de pivotement du guide est confondu avec l'axe 2 des tourillons.The pivoting capacity of the guide 110 nevertheless allows to accompany the pivoting site of the weapon on its trunnions. This movement is done without blocking or deformation of the corridor / guide 110 because the axis 12 of pivoting of the guide coincides with the axis 2 of the trunnions.

Le recul de l'arme 1 entraîne donc un déplacement de l'entonnoir d'introduction 34 vers l'arrière (figure 9b), les munitions restent guidées par la lame 28 dans le guide/couloir 110 puis par le doigt avant 33 et la languette arrière 32 dans l'entonnoir 34. Elles arrivent donc toujours correctement positionnées à l'arme malgré la rigidité du guide/couloir 110.The recoil of the weapon 1 thus causes a displacement of the insertion funnel 34 towards the rear ( figure 9b ), the ammunition remains guided by the blade 28 in the guide / corridor 110 and by the front finger 33 and the rear tongue 32 in the funnel 34. They always arrive correctly positioned to the weapon despite the rigidity of the guide / corridor 110.

Après le recul maximal, l'arme 1 revient en batterie (flèche CR), la position de contre recul maximal est représentée à la figure 9c.After the maximum recoil, the weapon 1 comes back in battery (arrow CR), the position of maximum recoil is represented at the Figure 9c .

Le mouvement de contre recul de l'arme 1 entraîne un déplacement de l'entonnoir d'introduction 34 vers l'avant (figure 9c), les munitions restent encore guidées par la lame 28 dans le guide/couloir 110 puis par le doigt avant 33 et la languette arrière 32 dans l'entonnoir 34.The recoil movement of the weapon 1 causes the insertion funnel 34 to move forward ( Figure 9c ), the ammunition is still guided by the blade 28 in the guide / corridor 110 and then by the front finger 33 and the rear tongue 32 in the funnel 34.

Ce mode de réalisation présente comme le précédent l'avantage d'assurer l'alimentation en munitions d'une arme à l'aide d'un couloir rigide, donc de fabrication très simplifiée et de coût est réduit.This embodiment has the previous advantage of ensuring the supply of ammunition of a weapon using a rigid corridor, so very simplified manufacturing and cost is reduced.

Il est bien entendu possible de combiner les deux modes de réalisation précédents.It is of course possible to combine the two previous embodiments.

Dans tous les cas, grâce à l'invention, les bandes de munitions sont mieux protégées contre l'humidité qu'avec des couloirs souples. Une telle caractéristique est particulièrement intéressante pour les armes navales. Le couloir étant ainsi composé de très peu de pièces en mouvement, les problèmes de corrosions s'en trouvent réduits considérablement.In any case, thanks to the invention, the ammunition strips are better protected against moisture than with flexible corridors. Such a characteristic is particularly interesting for naval weapons. As the corridor is composed of very few moving parts, corrosion problems are considerably reduced.

L'invention décrit ici pour une arme de moyen calibre (calibre compris entre 20mm et 50mm) pourrait bien entendu être mise en oeuvre avec des armes de petit calibre (calibre compris entre 5,56 et 20mm).The invention described here for a medium caliber weapon (caliber between 20mm and 50mm) could of course be implemented with small arms (caliber between 5.56 and 20mm).
