Description

L'invention a pour objet un dispositif d'alimentation d'une arme en munitions, spécialement adaptée à des munitions fragiles.The subject of the invention is a device for supplying a weapon with ammunition, specially adapted for fragile munitions.

Pour l'alimentation en munitions d'une arme telle qu'un canon, comprenant un tube monté sur une masse oscillante articulée sur un affût, on doit utiliser, pour obtenir une cadence de tir élevée, un couloir de chargement dans lequel la munition est amenée automatiquement depuis une réserve jusqu'à la culasse de l'arme. Le couloir de chargement comprend donc des organes de guidage entre lesquels la munition est poussée par des moyens de transport automatique. Ainsi, lorsque la munition doit se déplacer parallèlement à son axe, ce déplacement est provoqué généralement par des plateaux à alvéoles. En revanche, un déplacement le lang de l'axe est effectué par un refouloir comprenant un poussoir qui prend appui sur la munition et qui se déplace le long d'une direction parallèle à l'axe de celle-ci.To supply ammunition to a weapon such as a barrel, comprising a tube mounted on an oscillating mass articulated on a mount, one must use, to obtain a high rate of fire, a loading lane in which the ammunition is automatically brought from a reserve to the breech of the weapon. The loading corridor therefore comprises guide members between which the ammunition is pushed by means of automatic transport. Thus, when the ammunition must move parallel to its axis, this movement is generally caused by trays with cells. On the other hand, a displacement the lang of the axis is carried out by a repressor comprising a pusher which bears on the ammunition and which moves along a direction parallel to the axis of the latter.

Le couloir de chargement est constitué généralement de plusieurs parties, par exemple une partie solidaire de la machine oscillante et une partie fixe montée sur l'affût et qui peut être constituée d'un magasin comportant une série d'emplacements de munitions formant une chaine fermée, associés à une suite de plateaux à alvéoles.The loading corridor generally consists of several parts, for example an integral part of the oscillating machine and a fixed part mounted on the carriage and which can consist of a magazine comprising a series of ammunition locations forming a closed chain , associated with a series of cell trays.

Bien que les différentes parties du couloir de chargement soient munies d'organes de guidage des munitions, il est difficile de caler correctement celles-ci dans le couloir de chargement ou le magasin dt les chocs auxquels sont soumises les munitions lorsque l'arme est montée par exemple sur un véhicule blindé peuvent entrainer une détenoration du couloir de chargement et même des munitions lorsque celles-ci sont fragiles. Or c'est le cas précisément, d'une munition comportant un obus associé à une douille en matière combustible assez peu résistante et qui doit toujours être bien supportée sur toute sa longueur pour que l'obus reste solidaire de la douille combustible.Although the different parts of the loading lane are equipped with ammunition guiding members, it is difficult to correctly wedge them in the loading lane or the shock store to which the ammunition is subjected when the weapon is mounted for example on an armored vehicle can cause a detenoration of the loading lane and even ammunition when these are fragile. However, this is precisely the case with ammunition comprising a shell associated with a socket of combustible material that is not very resistant and which must always be well supported over its entire length so that the shell remains integral with the combustible socket.

On a déjà proposé (D E-A-2.153.327 ou FR-A-2.443.041) de protéger la munition en la plaçant dans un conteneur tubulaire muni ,le long de sa périphérie,d'organes d'appui qui maintiennent la munition dans l'axe du conteneur. En outre, dans le document FR-A-2.443.041, par exemple, le conteneur est constitué de deux tubes coulissant télescopiquement l'un dans l'autre; le tube interne peut . ainsi former un pont entre le magasin et la culasse, pour le chargement de la munition et, lorsqu'il est rétracté à l'intérieur du tube externe, libérer l'espace nécessaire pour le recul de la culasse. D'autre part, les plots de calage sont constitués par des plaques fixées à l'extrémité de lames flexibles dont l'autre extrémité est solidaire du tube interne, celui-ci étant muni d'un orifice pour le passage de la plaque et de sa lame flexible. Ainsi, lorsque le tube interne est rentré à l'intérieur du tube externe, celui-ci pousse vers l'intérieur les plots de calage qui s'appuient sur le projectile. En revanche, lorsque le tube externe est sorti, les lames flexibles qui échappent au tube externe écartent les plots de calage vers l'extérieur en libérant la munition qui peut ainsi coulisser pour le chargement du canon.It has already been proposed (D EA-2,153,327 or FR-A-2,443,041) to protect the ammunition by placing it in a tubular container provided, along its periphery, with supporting members which hold the ammunition in the axis of the container. In addition, in the document FR-A-2,443,041, for example, the container consists of two tubes sliding telescopically one inside the other; the inner tube can. thus form a bridge between the magazine and the breech, for the loading of the ammunition and, when it is retracted inside the external tube, to free the space necessary for the retreat of the cylinder head. On the other hand, the wedging pads are constituted by plates fixed to the end of flexible blades, the other end of which is integral with the internal tube, the latter being provided with an orifice for the passage of the plate and of its flexible blade. Thus, when the internal tube has returned to the interior of the external tube, the latter pushes inward the wedging pads which are supported on the projectile. On the other hand, when the external tube is out, the flexible blades which escape from the external tube spread the wedging studs outwards, releasing the ammunition which can thus slide for loading the barrel.

Un tel dispositif est envisageable lorsque le magasin se trouve à proximité du canon de façon que la distance parcourue par la munition sans appui ne soit pas trop importante. Ceci implique que le magasin soit monté sur la masse oscillante solidaire du canon et orientable avec lui autour de l'axe des tourillons.Such a device is possible when the magazine is near the barrel so that the distance traveled by the munition without support is not too great. This implies that the magazine is mounted on the oscillating mass integral with the barrel and orientable with it around the axis of the trunnions.

Cependant, dans certains cas, le magasin doit être placé sur l'affût et il est alors écarté de la culasse par une distance relativement importante.However, in some cases, the magazine must be placed on the carriage and it is then moved away from the cylinder head by a relatively large distance.

Pour franchir cette distance, on a déjà proposé, dans le document DE-A-1.938.681, de placer entre le magasin et la culasse un tube télescopique qui, en position rentrée, permet le recul de la culasse et, en position déployée, forme un conduit de liaison par lequel la munition peut passer du magasin jusqu'à la culasse lorsque le canon, bien entendu, est placé en position de chargement.To cross this distance, it has already been proposed, in document DE-A-1,938,681, to place between the magazine and the cylinder head a telescopic tube which, in the retracted position, allows the cylinder head to recede and, in the deployed position, forms a connecting conduit through which the ammunition can pass from the magazine to the breech when the barrel, of course, is placed in the loading position.

Un tel dispositif, cependant, est prévu pour des munitions normales et n'assure pas le maintien de celles-ci lorsqu'elles sont munies d'une douille combustible.Such a device, however, is intended for normal munitions and does not ensure their maintenance when they are provided with a combustible case.

L'invention a pour objet des dispositions perfectionnées permettant sur toue sa Longueur de maintenir la murition/non seulement à l'intérieur du conteneur replié mais également lorsque le conteneur est déplié et pendant le déplacement de la munition par rapport à celui-ci. deuxThe subject of the invention is improved provisions enabling its length to be maintained over all its length / not only inside the folded container but also when the container is unfolded and during the movement of the ammunition relative thereto. of them

Selon l'invention, le conteneur télescopique est muni d'au moins/ rangées de plots de calage écartées l'un de l'autre pour le maintien,res-. pectivement, de la douille et de l'obus et, après déverrouillage, chaque plot est maintenu en position de calage par sa lame flexible et constitue un appui élastique susceptible d'être écarté vers l'extérieur par le passage d'une partie de la munition à section plus grande que celle correspondante à la position de calage, le déverrouillage des plots étant commandé par rangées successives au cours du déplacement de la munition par rapport au tube externe.According to the invention, the telescopic container is provided with at least / rows of wedging studs spaced from one another for holding, res. pectively, from the shell and the shell and, after unlocking, each stud is held in the chocking position by its flexible blade and constitutes an elastic support capable of being spread outwards by the passage of part of the ammunition with a larger section than that corresponding to the chocking position, the unlocking of the studs being controlled by successive rows during the movement of the ammunition relative to the outer tube.

L'invention s'applique en particulier au cas où les munitions placées chacune à l'intérieur d'un conteneur télescopique sont disposées dans un magasin de réserve écarté de la culasse par un espace relativement important. Selon cette caractéristique particulière, le dispositif comprend un conteneur télescopique placé dans l'axe de chargement de la culasse pour former un tube de liaison entre celle-ci et le magasin, ce conteneur étant dépourvu de fond et constitué lui-même par un tube externe et un tube interne sur lequel sont montés des plots de calage de la munition. Celle-ci est poussée par un organe de refoulement depuis le magasin jusqu'à la culasse et guidée de façon continue par les plots du conteneur du magasin puis du tube de liaison qui sont verrouillés et déverrouillés par rangées successives au cours de l'avancement de la munition.The invention applies in particular to the case where the munitions each placed inside a telescopic container are arranged in a reserve magazine spaced from the cylinder head by a relatively large space. According to this particular characteristic, the device comprises a telescopic container placed in the axis of loading of the cylinder head to form a connection tube between the latter and the magazine, this container being devoid of bottom and constituted itself by an external tube. and an internal tube on which are mounted wedges of the ammunition. This is pushed by a delivery device from the magazine to the cylinder head and guided continuously by the studs of the magazine container then of the connecting tube which are locked and unlocked in successive rows during the advancement of ammunition.

De la même façon, d'autres parties du couloir de chargement pourraient être constituées par un conteneur télescopique formant un tube à l'intérieur duquel est guidée la munition en s'appuyant sur les plots de calage. Il est ainsi possible d'écarter les différentes parties du couloir de chargement en laissant des espaces libres pour le passage de pièces mécaniques, ces espaces étantoccupés , au moment du chargement, par le dépliement du tube interne.In the same way, other parts of the loading corridor could be constituted by a telescopic container forming a tube inside which the ammunition is guided by resting on the wedging pads. It is thus possible to separate the different parts of the loading passage, leaving free spaces for the passage of mechanical parts, these spaces being occupied, at the time of loading, by the unfolding of the internal tube.

D'autre part, il pourra être nécessaire de commander le verrouillage et le déverrouillage des plots non seulement par le mouvement du tube interne par rapport au tube externe mais également par le mouvement propre de la munition. A cet effet, dans un mode de réalisation préférentiel, le tube externe est muni, pour chaque plot, d'un orifice et d'une échancrure de sections égales .respectivement,à celles du plot et de la lame flexible et dont la position le long du conteneur calée longitudinalement par rapport au niveau du plot en position repliée d'une distance égale à l'avancement du tube interne en position de déverrouillage, et, pour une partie au moins des plots, l'orifice de passage de ce dernier est fermé par un obturateur mobile dont l'ouverture est commandée,pour une position déterminée de la munition, par le déplacement de celle-ci dans le tube interne.On the other hand, it may be necessary to control the locking and unlocking of the studs not only by the movement of the internal tube relative to the external tube but also by the proper movement of the ammunition. To this end, in a preferred embodiment, the external tube is provided, for each pad, with an orifice and a notch with sections equal .respectively, to those of the pad and of the flexible blade and whose position the along the container wedged longitudinally with respect to the level of the stud in the folded position by a distance equal to the advancement of the internal tube in the unlocked position, and, for at least part of the studs, the orifice for the passage of the latter is closed by a movable shutter, the opening of which is controlled, for a determined position of the ammunition, by the displacement of the latter in the internal tube.

Sur la figure 1, on a représenté schématiquement, en coupe longitudi- nale,la partie arriere d'un tube de canon 11 monté sur un véhicule blindé 1 et muni d'une culasse 12, l'ensemble étant fixé sur une masse oscillante articulée sur le véhicule 1 autour d'un axe horizontal 10 d'orientation en site.In Figure 1, there is shown schematically, in longitudinal section, the rear part of a barrel tube 11 mounted on an armored vehicle 1 and provided with a cylinder head 12, the assembly being fixed on an articulated oscillating mass on the vehicle 1 around a horizontal axis 10 of elevation orientation.

Les munitions sont placées en réserve dans un magasin 2 placé sur l'arrière du véhicule, et qui est représenté schématiquement en coupe sur la figure 3. Dans l'exemple représenté, le magasin, limité par deux parois transversales 21, comprend une série de plateaux à alvéoles 22 disposées par paires sur des axes 23 disposés suivant un plan horizontal. De façon bien connue, les munitions entrainées par les plateaux à alvéoles imbriqués forment une chaine sans fin.The ammunition is placed in reserve in a magazine 2 placed on the rear of the vehicle, and which is shown diagrammatically in section in FIG. 3. In the example shown, the magazine, limited by two transverse walls 21, comprises a series of cell trays 22 arranged in pairs on axes 23 arranged in a horizontal plane. As is well known, the ammunition driven by the nested cell trays form an endless chain.

Dans les magasins de types connus, les deux alvéoles de chaque paire 22 prennent en charge les munitions l'une à la hauteur du plateau de douille et l'autre à la hauteur du sertissage de l'obus. Cette disposition convient parfaitement lorsque les munitions ont une douille métallique et sont très rigides. En revanche, des munitionsplus fragiles/comme celles qui ont une douille combustiblelne peuvent pas être retenues en deux points seulement surtout lorsque le canon est monté sur un véhicule soumis à des accélérations horizontales et verticales. C'est pourquoi chaque munition est placée dans un conteneur tubulaire 3 muni de plots de calage. Ainsi, comme on le voit sur la figure 3, les plateaux à alvéoles 22, symbolisés par des croix sur la figure, s'engageront non pas directement sur les munitions M mais sur la périphérie des conteneurs 3 contenant chacun une munition. Il en résulte évidemment que le diamètre des alvéoles doit être agrandi pour correspondre à celui des conteneurs 3 qui est sensiblement supérieur au diamètre des munitions.In stores of known types, the two cells of each pair 22 take care of the ammunition, one at the level of the shell plate and the other at the height of the crimping of the shell. This arrangement is perfectly suited when the ammunition has a metal case and is very rigid. On the other hand, more fragile munitions / like those which have a combustible case l cannot be retained at two points only especially when the gun is mounted on a vehicle subjected to horizontal and vertical accelerations. This is why each munition is placed in a tubular container 3 provided with wedging pads. So like it can be seen in FIG. 3, the cell trays 22, symbolized by crosses in the figure, will not engage directly on the ammunition M but on the periphery of the containers 3 each containing an ammunition. It obviously follows that the diameter of the cells must be enlarged to correspond to that of the containers 3 which is substantially greater than the diameter of the ammunition.

Selon une autre caractéristique de l'invention, étant donné que le magasin 2 doit être placé en arrière de la cabine, l'espace compris entre la sortie du magasin 2 et la culasse 12 est occupé par un conteneur 4 analogue aux conteneurs 3 placés dans le magasin 2 et qui sert de conduit de guidage de la munition jusque dans la culasse 12. Cependant, pour des raisons mécaniques, la partie arrière du conteneur 4 doit être placée à me certaine distance de la sortie du magasin et c'est pourquoi, pour franchir cet espace tout en maintenant la munition guidée, chaque conteneur 3 est constitué d'untube interne 31 et d'un tube externe 2 coulissant télescopiquement l'un dans l'autre. Il en est de même du conteneur 4 qui est constitué d'un tube interne 41 et d'un tube externe 42 de façon à faire la liaison avec la culasse 12.According to another characteristic of the invention, since the magazine 2 must be placed behind the cabin, the space between the outlet of the magazine 2 and the cylinder head 12 is occupied by a container 4 similar to the containers 3 placed in the magazine 2 and which serves as a conduit for guiding the ammunition as far as the breech 12. However, for mechanical reasons, the rear part of the container 4 must be placed at a certain distance from the outlet of the magazine and that is why, to cross this space while maintaining the guided munition, each container 3 consists of an inner tube 31 and an outer tube 2 telescopically sliding one inside the other. It is the same for the container 4 which consists of an internal tube 41 and an external tube 42 so as to make the connection with the cylinder head 12.

A l'intérieur de chaque conteneur, la munition M est maintenue par une pluralité d'organes de calage constitués de plots 6 répartis autour de la munition et sur toute la longueur de celle-ci. Comme on l'a représenté par exemple sur la figure 1, le diamètre intérieur du tube interne 31 est égal à celui du plateau de douille M1 de la munition M. De la sorte, la munition peut être maintenue suffisamment par deux séries de plots 6 placés dans deux plans transversaux écartés l'un de l'autre de telle sorte que les plots d'une série s'appuient sur l'obus et les plots de l'autre série sur la douille, à proximité du sertissage (figure 4).Inside each container, the munition M is held by a plurality of wedging members made up of studs 6 distributed around the munition and over the entire length of the latter. As shown for example in Figure 1, the inner diameter of the inner tube 31 is equal to that of the socket plate M1 of the ammunition M. In this way, the ammunition can be held sufficiently by two series of studs 6 placed in two transverse planes spaced from each other so that the studs of one series rest on the shell and the studs of the other series on the socket, near the crimping (Figure 4) .

Chaque plot 6 est fixé à l'extrémité d'une lame flexible 61 placée le long de la paroi extérieure du tube interne 31, sur laquelle elle est encastrée à son autre extrémité. En outre, le plot '6 pénètre vers l'intérieur du conteneur 3 par un orifice 34 ménagé sur la paroi du tube interne 31.Each stud 6 is fixed to the end of a flexible blade 61 placed along the outer wall of the internal tube 31, on which it is embedded at its other end. In addition, the stud 6 penetrates towards the interior of the container 3 through an orifice 34 formed on the wall of the internal tube 31.

Lorsque la lame 61 se trouve le long de la paroi du tube 31, le plot 6 dépasse vers l'extérieur du tube 31 d'une hauteur e correspondant à l'intervalle existant entre les parois des tubes 31 et 32 et vient donc s'appuyer contre la paroi intérieure du tube 32 qui le verrouille dans cette position. La hauteur totale h du plot 6 est déterminée, en fonction de la position du plot le long de la munition, pour que celui-ci pénètre vers l'intérieur du tube 31 sur une distance qui, dans ce plan, correspond à la différence de diamètre entre la munition et le tube 31. Ainsi, lorsque les deux tubes sont repliés l'un dans l'autre, les plots 6 sont verrouillés et assurent le calage de la munition, celui-ci étant obtenu dans de bonnes de conditions si l'on dispose dans chaque plan d'appui/trois plots centrés dans des plans axiaux angulairement écartés de 120°. Dans ces plans axiaux sont centrés trois fentes 35 ménagées dans la paroi du tube externe 32, l'une de ces fentes étant représentée sur la figure 6. Ces fentes permettent de déverrouiller les plots 6 pour certaines positions relatives des tubes 31 et 32, comme on va le voir en se référant à la figure 11 qui représente les étapes successives de l'avancement d'une munition d'un conteneur 3 du magasin jusqu'au conteneur 4. Pour simplifier, on a représenté uniquement sur la figure 11 les postions relatives des tubes internes et externes du conteneur 3 et des plots qui sont placés dans le plan de la figure.When the blade 61 is located along the wall of the tube 31, the stud 6 protrudes towards the outside of the tube 31 by a height e corresponding to the interval existing between the walls of the tubes 31 and 32 and therefore comes s' press against the inner wall of the tube 32 which locks it in this position. The total height h of the stud 6 is determined, as a function of the position of the stud along the munition, so that it penetrates towards the inside of the tube 31 over a distance which, in this plane, corresponds to the difference in diameter between the ammunition and the tube 31. Thus, when the two tubes are folded one inside the other, the studs 6 are locked and ensure the timing of the munition, the latter being obtained in good conditions if there are in each support plane / three studs centered in axial planes angularly spaced by 120 °. In these axial planes are centered three slots 35 formed in the wall of the external tube 32, one of these slots being shown in FIG. 6. These slots allow the studs 6 to be unlocked for certain relative positions of the tubes 31 and 32, as we will see it with reference to FIG. 11 which represents the successive stages of advancing an ammunition from a container 3 from the store to the container 4. For simplicity, the positions are shown only in FIG. 11 relative internal and external tubes of the container 3 and the pads which are placed in the plane of the figure.

La figure lla correspond à la figure 4, les plots 62 et 63étant verrouillés. En effet, comme on le voit sur les figures 4 et 6, si la fente 35 s'étend en face des plots 62, ceux-ci ont cependant, dans cette position, une largeur supérieure à celle de la fente et restent verrouillés. Par ailleurs, les plots 63 sont placés devant une partie pleine du tube externe 32.Figure lla corresponds to Figure 4, the pads 62 and 63 being locked. In fact, as can be seen in FIGS. 4 and 6, if the slot 35 extends opposite the studs 62, the latter, however, in this position, have a width greater than that of the slot and remain locked. Furthermore, the studs 63 are placed in front of a solid part of the external tube 32.

L'allongement du conteneur télescopique est produit par l'organe de déplacement de la munition qui s'appuie sur celle-ci et provoque en même temps l'avancement du tube interne 81. Cet organe de déplacement peut être constitué de façon classique par un refouloir 5 comprenant une chaine sans fin munie d'une butée 51 qui se déplace suivant une direction parallèle à. l'axe 30 de la munition M en prenant appui sur le plateau de douille Ml. A cet effet la butée 51 coulisse dans deux fentes superposées 33 ménagées dans un plan axial sur les tubes 31 et 32 (figure 4).The elongation of the telescopic container is produced by the displacement member of the ammunition which is supported thereon and at the same time causes the advancement of the internal tube 81. This displacement member can be constituted in a conventional manner by a repressor 5 comprising an endless chain provided with a stop 51 which moves in a direction parallel to. the axis 30 of the munition M taking support on the socket plate Ml. To this end, the stop 51 slides in two superimposed slots 33 formed in an axial plane on the tubes 31 and 32 (Figure 4).

Le magasin 2 est muni d'un refouloir unique 5 dvec lequel doivent coin- cider les fentes 33 des tubes en arrivant dans la position de coulissement. C'est pourquoi le tube interne 31 est guidé longitudinalement sur letube externe 32 et celui-ci est fermé par un fond 36 qui porte deux tétons de guidage 37 coulissant dans une rainure fermée 26 ménagée sur le fond 21du magasin 2 et empêchant les conteneurs 3 de tourner sur eux-mêmes.The magazine 2 is provided with a single repressor 5 dvec which must wedge the slots 33 of the tubes when arriving in the sliding position. This is why the inner tube 31 is guided longitudinally on the outer tube 32 and the latter is closed by a bottom 36 which carries two guide pins 37 sliding in a closed groove 26 formed on the bottom 21 of the magazine 2 and preventing the containers 3 to turn on themselves.

Le refouloir 5 provoque l'avancement de la munition M au moyen de la butée 51 qui s'appuie sur le plateau de douille M1 et il entraine en même temps le tube interne 31 grâce à une butée éclipsable 311 représentée sur la figure 6. Lorsque le refouloir pousse la munition M, le plateau de douille Ml s'appuie sur la butée 311 qui est montée pivotante sur le tube inter-ne 31 de façon à basculer et à libérer le tube 31 lorsqu'elle renc,ontre une cale 321 fixée sur le tube externe 32. Au même instant, une butée 310 fixée sur le tube 31 et coulissant dans une fente 320 du tube 32 est arrêtée par le fond de la fente 320 et bloque le tube 31 dans cette position représentée sur la figure 11b qui assure la continuité avec le conteneur 4.The repressor 5 causes the ammunition M to advance by means of the stop 51 which rests on the socket plate M1 and at the same time drives the internal tube 31 thanks to an eclipsable stop 311 shown in FIG. 6. When the repeller pushes the ammunition M, the cartridge tray the ML rests on the stop 311 which is pivotally mounted on the tube i n t e r-ne 3 1 so as to tilt and release the tube 31 when it encounters, there is a wedge 321 fixed on the external tube 32 At the same instant, a stop 310 fixed on the tube 31 and sliding in a slot 320 of the tube 32 is stopped by the bottom of the slot 320 and blocks the tube 31 in this position shown in FIG. 11b which ensures continuity with the container 4.

Dans cette position, chaque plot 62 se trouve placé en face d'un orifice 38 disposé à l'extrémité de la fente 35 et de section régale à celle du plot ; celui-ci n'est alors plus verrouillé et peut s'écarter vers l'extérieur en opposant la résistance élastique de la lame 61. En même temps le plot 63 placé sur l'arrière et de largeur inférieure à celle de la fente 35 vient se placer en face de la partie arrière de celle-ci et est donc également déverrouillée. Ainsi danscette position, la munition est soutenuedefaçon élastique par les deux séries de plots 62 et 63. Lorsque le refouloir 5 continue à faire avancer la munition, celle-ci coulisse le long des plots qui, maintenus par les lames élastiques 61, peuvent s'écarter au passage du sertissage et du plateau de douille Ml. La munition continue à avancer en pénétrant à l'intérieur du tube interne 41 du conteneur 4 et, dans la position d, vient s'appuyer sur des plots 64 placés à l'arrière du conteneur 4 pour prendre en charge la douille M3. Dans cette position, les plots 64 sont verrouillés, les deux tubes 41 et 42 du conteneur 4 étant repliés l'un dans l'autre.In this position, each pad 62 is placed in front of an orifice 38 disposed at the end of the slot 35 and of section equal to that of the pad; it is then no longer locked and can move outwards by opposing the elastic resistance of the blade 61. At the same time the stud 63 placed on the rear and of width less than that of the slot 35 comes stand in front of the rear part of it and is therefore also unlocked. Thus in this position, the munition is supported in an elastic manner by the two series of studs 62 and 63. When the repressor 5 continues to advance the munition, the latter slides along the studs which, maintained by the elastic blades 61, can move aside from the crimping and the Ml socket plate. The munition continues to advance while penetrating inside the internal tube 41 of the container 4 and, in position d, comes to rest on studs 64 placed at the rear of the container 4 to take charge of the socket M3. In this position, the studs 64 are locked, the two tubes 41 and 42 of the container 4 being folded one inside the other.

Le plateau de douille Ml passe alors sur les plots 62 qui, étant déverrouillés, s'écartent pour le laisser passer et la munition pénètre complètement dans le conteneur 4, dans la position (e). Ainsi, grâce aux dispositions selon l'invention, la munition est sortie du magasin tout en restant guidée par des plots élastiques à l'intérieur d'un conduit tubulaire continu.The socket plate M1 then passes over the studs 62 which, being unlocked, move apart to let it pass and the ammunition completely penetrates into the container 4, in position (e). Thus, by virtue of the arrangements according to the invention, the ammunition leaves the store while remaining guided by elastic studs inside a continuous tubular conduit.

Le conteneur 4 représenté sur la figure 7 est muni de la même façon de plots élastiques de calage de la munition. Cependant, étant donné que le conteneur 4 assure la liaison avec la culasse 12 du canon, il est indispensable qu'au moment du déchargement, la nunition se trouve placée exactement dans l'axe (13) du tube. Or, lorsque la munition est maintenue par des plots élastiques, les accélérations verticales auquel est soumis le véhicule pourraient entrainer un léger déplacement de l'axe de la munition. C'est pourquoi l'on préfère utiliser les moyens de verrouillage représentés sur les figures 8, 9, 10.The container 4 shown in FIG. 7 is likewise provided with elastic studs for wedging the ammunition. However, since the container 4 provides the connection with the breech 12 of the barrel, it is essential that at the time of unloading, the munition is placed exactly in the axis (13) of the tube. However, when the ammunition is held by elastic studs, the vertical accelerations to which the vehicle is subjected could cause a slight displacement of the axis of the ammunition. This is why it is preferred to use the locking means shown in FIGS. 8, 9, 10.

Pour assurer un meilleur guidage de la munition le conteneur 4 est muni de quatre séries de plots écartées les unes des autres.To ensure better guidance of the munition, the container 4 is provided with four series of studs spaced from one another.

En effet, aux deux rangées de plots 62 et 63 s'appuyant respectivement sur l'obus M4 et sur la partie avant de la douille M3 doivent s'ajouter d'une part à l'arrière du conteneur, les plots 64 qui prennent en charge la douille M3 à l'arrivée de celle-ci dans le conteneur et d'autre part, à l'avant de celui-ci, des plots 65 qui guident la partie arrière de la douille lorsque la munition quitte le conteneur 4 pour pénétrer complètement dans la culasse 12.Indeed, to the two rows of studs 62 and 63 resting respectively on the shell M4 and on the front part of the socket M3 must be added on the one hand to the rear of the container, the studs 64 which take into account loads the socket M3 on arrival of the latter in the container and on the other hand, at the front thereof, studs 65 which guide the rear part of the socket when the ammunition leaves the container 4 to penetrate completely in the cylinder head 12.

Dans la position de la figure 12a, qui correspond à la figure 11e, la munition M est placée entièrement à l'intérieur du conteneur 4, celui-ci étant replié. La munition est alors supportée par les plots 62, 63, 64 tous verrouillés.In the position of Figure 12a, which corresponds to Figure 11e, the ammunition M is placed entirely inside the container 4, the latter being folded. The ammunition is then supported by the pads 62, 63, 64 all locked.

de guidage Les plots placés à la partie supérieure du conteneurlet qui, par conséquent ne supportent pas le poids de la munition, fonctionnent de la même façon que ceux du conteneur 3, c'est à dire sont déverrouillés lorsque le plot, par l'avancement du tube interne, arrive devant un orifice de largeur supérieure pratiquée dans le tube externe. En revanche, pour le verrouillage des plots placés à la partie inférieure et qui supporte le poids de la munition, on utilise une disposition différente représentée sur les figures 8, 9 et 10.guide The studs placed at the top of the containerlet which, consequently do not support the weight of the ammunition, function in the same way as those of the container 3, that is to say are unlocked when the stud, by advancement of the inner tube, arrives at an orifice of greater width made in the outer tube. On the other hand, for the locking of the studs placed at the bottom and which supports the weight of the ammunition, a different arrangement is used, shown in Figures 8, 9 and 10.

Comme dans le cas du conteneur 3 au début du chargement, le tube interne 41, s'avance, en même temps que la munition, d'une longueur 1 déterminée par la longueur d'une fente longitudinale 420 pratiquée sur l'arrière du tube externe 42 et dans laquelle couliss une butée 410 solidaire du tube interne 41. Dans cette position, tous les plots du conteneur 4 viennent se placer devant des orifices 46 ménagés dans le tube externe 42 et qui permettent donc aux plots 6 de s'écarter vers l'extérieur. Cependant, pour maintenir le plot verrouillé, chaque orifice 46 est fermé par un obturateur 7 placé à l'extrémité d'un bras 71 articulé autour d'un pivot 72 centré sur un axepassant par le plan médian du plot 6 correspondant et monté sur un support 73 solidaire du tube externe 42 du conteneur 4.As in the case of the container 3 at the start of loading, the internal tube 41, advances, at the same time as the ammunition, by a length 1 determined by the length of a longitudinal slot 420 formed on the rear of the tube external 42 and in which slides a stop 410 integral with the internal tube 41. In this position, all the pads of the container 4 are placed in front of orifices 46 formed in the external tube 42 and which therefore allow the pads 6 to move towards outside. However, to keep the stud locked, each orifice 46 is closed by a shutter 7 placed at the end of an arm 71 articulated around a pivot 72 centered on an axis passing through the median plane of the corresponding stud 6 and mounted on a support 73 secured to the outer tube 42 of the container 4.

Le bras de support 71 est prolongé par un bras de commande 74, l'ensemble formant un levier coudé, de telle sorte que le bras 74 s'étende vers l'axe du conteneur pour s'interposer sur le passage de la butée 53 du refouloir 52 associé au conteneur 4. Ainsi, comme on l'a représenté sur la figure 9, lorsque la butée 53 s'avance dans le sens de la flèche, elle pousse sur le bras 74 qui commande le pivotement du bras 71 et l'ouverture de la fenêtre 46 permettant le déverrouillage du plot 6 correspondant.The support arm 71 is extended by a control arm 74, the assembly forming a bent lever, so that the arm 74 extends towards the axis of the container to interpose on the passage of the stop 53 of the repressor 52 associated with the container 4. Thus, as shown in FIG. 9, when the stop 53 advances in the direction of the arrow, it pushes on the arm 74 which controls the pivoting of the arm 71 and the opening of the window 46 allowing the unlocking of the corresponding stud 6.

de guidage , Les étapes du fonctionnement du conteneur 4 sont schématisées sur la figure 12. Au début de l'avancement de la munition, celle-ci, au moyen d'une butée éclipsable, entraine avec elle le tube interne 41 jusqu'à ce que celui-ci vienne en butée dans la position de la figure 12. Le tube interne 41 fait alors la liaison avec la culasse 12 et, comme on l'a indiqué, tous les plots supérieurs sont déverrouillés, réalisant un appui élastique de la munition tout le long de sa génératrice supérieure. Et il en est de même des plots 64 placés à l'arrière du tube interne 41 et des plots 62 placés à l'avant et qui viennent tous se placer devant des orifices du tube externe 42 permettant leur déverrouillage comme on l'a décrit pour le conteneur 3. En revanche, dans le milieu du conteneur 4, seul le plot supérieur 63 est déverrouillé, car les deux plots inférieurs sont placés devant des ouvertures 46 qui restent fermées par les obturateurs 7.The stages of operation of the container 4 are shown diagrammatically on the Figure 12. At the beginning of the advancement of the ammunition, the latter, by means of an eclipsable stop, drives with it the internal tube 41 until the latter comes into abutment in the position of Figure 12 The internal tube 41 then makes the connection with the breech 12 and, as indicated, all of the upper studs are unlocked, providing elastic support for the ammunition all along its upper generatrix. And it is the same for the studs 64 placed at the rear of the internal tube 41 and the studs 62 placed at the front and which all come to be placed in front of the orifices of the external tube 42 allowing them to be unlocked as has been described for the container 3. On the other hand, in the middle of the container 4, only the upper stud 63 is unlocked, since the two lower studs are placed in front of openings 46 which remain closed by the shutters 7.

Il en est de même des plots 65 placés à l'avant du tube 41 et qui, dans la position b, restent verrouillés par la paroi du tube extenne 42.The same is true of the studs 65 placed at the front of the tube 41 and which, in position b, remain locked by the wall of the external tube 42.

Ainsi, lorsque le refouloir 53 continue à repousser la munition M, le tube interne 41 restant bloqué, la munition coulisse le long de l'ensemble des plots et le plateau de douille M1 passe sur les plots 64 qui, maintenus par les lames élastiques, s'écartent pour le laisser passer.Thus, when the repressor 53 continues to repel the ammunition M, the internal tube 41 remaining blocked, the ammunition slides along all of the studs and the socket plate M1 passes over the studs 64 which, held by the elastic blades, move aside to let it pass.

Les plots 65 qui sont placés à l'avant du tube interne 41 restent verrouillés pendant la plus grande partie du déplacement de la munition à l'intérieur du tube 41. Leur position est déterminée de telle sorte que, au moment où le projectile pénètre dans le tube du canon, c'est à dire sensiblement dans la positionner la partie antérieure de la douille M3 s'appuie sur les plots verrouillés 65 qui maintiennent ainsi l'alignement de la munition dans l'axe du tube et permettent sa pénétration. Dans cette position, les plots 63 se trouvent à proximité de la partie arrière de la douille. La butée 53 du refouloir 52 commande alors le pivotement des obturateurs 7 et l'ouverture des orifices 46 en s'appuyant sur le levier 74. Les plots inférieurs 63 sont alors déverrouillés et la position relative de la butée 53 et du plateau de douille M1 par rapport au plot 63 au moment du déverrouillage est déterminé par la longueur du bras 71.The studs 65 which are placed at the front of the internal tube 41 remain locked during most of the movement of the ammunition inside the tube 41. Their position is determined so that, at the moment when the projectile enters the barrel tube, that is to say substantially in the position the front part of the socket M3 rests on the locked studs 65 which thus maintain the alignment of the ammunition in the axis of the tube and allow its penetration. In this position, the studs 63 are located near the rear part of the socket. The stop 53 of the repressor 52 then controls the pivoting of the shutters 7 and the opening of the orifices 46 by pressing on the lever 74. The lower studs 63 are then unlocked and the relative position of the stop 53 and of the socket plate M1 relative to the stud 63 at the time of unlocking is determined by the length of the arm 71.

Les plots 63 ainsi déverrouillés s'écartent donc pour laisser passer le plateau de douille M1 et le refouloir introduit alors la munition dans le tube 11 du canon.The pads 63 thus unlocked therefore move apart to allow the bushing plate M1 to pass and the repressor then introduces the ammunition into the tube 11 of the barrel.

Au moment où le plateau de douille Ml arrive à proximité des plots verrouillés 65, la butée 53 du refouloir vient se bloquer sur le fond 411 de la fente 412 ménagée dans le tube interne 41 pour le passage de la butée 53 du refouloir. Le tube interne 41 avance alors d'une distance 1' et les plots 65 viennent se placer en face d'orifices 54 placés à l'extrémité du tube externe 42. Ils sont alors déverrouillés et peuvent donc s'écarter pour laisser passer le plateau de douille M1 au moment où celui-ci pénètre dans la culasse 13.When the socket plate Ml arrives near the locked studs 65, the stop 53 of the repressor comes to lock on the bottom 411 of the slot 412 formed in the internal tube 41 for the passage of the stop 53 of the repressor. The internal tube 41 then advances by a distance 1 ′ and the studs 65 are placed in front of orifices 54 placed at the end of the outer tube 42. They are then unlocked and can therefore move apart to allow the bushing plate M1 to pass when it enters the cylinder head 13 .

Ainsi, pendant tout son déplacement à l'intérieur du tube continu formé par le conteneur 4, la munition est toujours guidée et le deverrouillage des plots 63 interdit à la munition de s'incliner par rapport à l'axe du conteneur et permet donc son introduction dans le tube 11 du canon sans risque de désalignement.Thus, throughout its movement inside the continuous tube formed by the container 4, the ammunition is always guided and the unlocking of the studs 63 prevents the ammunition from tilting relative to the axis of the container and therefore allows its introduction into the tube 11 of the barrel without risk of misalignment.

On a donc assuré le maintien de la munition non seulement à l'intérieur du magasin mais également de façon continue, pendant tout son déplacement depuis le magasin jusqu'au tube du canon.It was therefore ensured that the ammunition was maintained not only inside the magazine but also continuously, throughout its movement from the magazine to the barrel tube.

Pendant l'introduction de la munition dans la culasse 12, le conteneur 4 doit évidemment être placé dans l'axe du canon mais s'il reste dans cette position pendant le tir, il doit être reculé par rapport à la culasse d'une distance correspondant au recul du canon causé par le tir. Ceci ne présente pas un grave inconvénient étant donné que l'on peut régler la distance 1 d'avancement du tube interne pour tenir compte de cette distance supplémentaire due au recul et assurer le guidage de la munition jusque dans la culasse, comme on l'a représenté sur la figure 12. Cependant, pour éviter d'avoir à reculer le conteneur et par conséquent diminuer l'allongement du tube télescopique, on peut placer le conteneur 4 sur un bâti pivotant lui permettant de s'écarter de l'axe du canon en dehors des périodes de chargement. A cet effet, on utilise par exemple la disposition représentée sur les figures 1 et 2 qui comprend avantageusement deux conteneurs 4a et 4b placés respectivementde part et d'autre du plan de symétrie B passant par l'axel10 du canon.During the introduction of the ammunition into the breech 12, the container 4 must obviously be placed in the axis of the barrel but if it remains in this position during the firing, it must be moved back with respect to the breech corresponding to the retreat of the barrel caused by the shooting. This does not present a serious drawback given that the distance 1 of advancement of the internal tube can be adjusted to take account of this additional distance due to recoil and to guide the ammunition as far as the breech, as is the case. shown in Figure 12. However, to avoid having to move the container back and therefore reduce the elongation of the telescopic tube, the container 4 can be placed on a pivoting frame allowing it to move away from the axis of the barrel outside loading periods. For this purpose, use is made, for example, of the arrangement shown in FIGS. 1 and 2 which advantageously comprises two containers 4a and 4b placed respectively on either side of the plane of symmetry B passing through the axel10 of the barrel.

Chacun des conteneurs 4a et 4b, associé à un refouloir 52, est monté sur un berceau 8 articulé autour d'un axe 80 sur un support fixe 81 et dont le basculement peut être commandé par un vérin 82 dont le corps et la tige sont articulés respectivement sur le berceau 8 et le support 81. Les deux axes 80 sont disposés symétriquement de part et d'autre du plan vertical de symétrie P de l'affût de telle sorte que, en position repliée des vérins 82, les deux conteneurs 4a et 4b soient alignés avec deux conteneurs 3a et 3b placés respectivement dans deux plateaux 24 et 25 du magasin 2 et que, par extension du vérin 82, l'un ou l'autre des conteneurs 4a et 4b vienne se centrer sur l'axe 13 du canon.Each of the containers 4a and 4b, associated with a repressor 52, is mounted on a cradle 8 articulated around an axis 80 on a fixed support 81 and the tilting of which can be controlled by a jack 82 whose body and rod are articulated respectively on the cradle 8 and the support 81. The two axes 80 are arranged symmetrically on either side of the vertical plane of symmetry P of the mount so that, in the folded position of the jacks 82, the two containers 4a and 4b are aligned with two containers 3a and 3b placed respectively in two trays 24 and 25 of the magazine 2 and that, by extension of the jack 82, one or the other of the containers 4a and 4b comes to center on the axis 13 of the cannon.

Ainsi, l'un des conteneurs, par exemple 4a peut être chargé d'une munition venant du conteneur 3a correspondant pendant que l'autre conteneur 4b introduit dans le tube la munition qu'il contient.Thus, one of the containers, for example 4a can be loaded with a muni tion from the corresponding container 3a while the other container 4b introduces into the tube the ammunition it contains.

De ce fait, la cadence de tir peut être augmentée. D'autre part, on peut aussi charger des deux côtés du magasin 2 deux types différents de munitions introduites dans le canon respectivement par les deux paires de conteneurs3a, 4a et 3b, 4b dont les caractéristiques, notamment les dimensions et la disposition des plots, peuvent être adaptées, éventuellement, à la forme de la munition.As a result, the rate of fire can be increased. On the other hand, it is also possible to load on two sides of the magazine 2 two different types of ammunition introduced into the barrel respectively by the two pairs of containers 3a, 4a and 3b, 4b whose characteristics, in particular the dimensions and the arrangement of the pads, can be adapted, if necessary, to the shape of the ammunition.

Cette possibilité d'effectuer le chargement des conteneurs 4a et 4b en dehors de l'axe 13 du tube permet également, comme on l'a représenté sur les figures 1 et 2, de placer dans le plan de symétrie P un conteneur télescopique supplémentaire 4c porté par un châssis 83 monté coulissant verticalement sur l'affût entre une position basse sur le plancher de l'affût et une position haute pour laquelle le conteneur 4c vient s'aligner avec l'axe 13 du canon. De la sorte, lorsque les deux conteneurs 4a et 4b sont écartés de part et d'autre du plan P, il est possible de faire monter très rapidement en position haute le châssis 83 pour placer le conteneur 4c sur l'axe 13 du tube et charger dans celui-ci une munition spéciale gardée en réserve, par exemple un obus fumigène.This possibility of loading the containers 4a and 4b outside the axis 13 of the tube also makes it possible, as shown in FIGS. 1 and 2, to place in the plane of symmetry P an additional telescopic container 4c carried by a frame 83 mounted vertically sliding on the carriage between a low position on the floor of the carriage and a high position for which the container 4c is aligned with the axis 13 of the barrel. In this way, when the two containers 4a and 4b are spaced on either side of the plane P, it is possible to very quickly raise the frame 83 to the high position in order to place the container 4c on the axis 13 of the tube and load in it a special ammunition kept in reserve, for example a smoke shell.

On voit que les dispositions revendiquées s'adaptent à différents types de chargement et, d'une façon générale, l'invention ne se limite évidemment pas aux modes de réalisation décrits, d'autres variantes pouvant être imaginées.We see that the claimed arrangements adapt to different types of loading and, in general, the invention is obviously not limited to the embodiments described, other variants can be imagined.
