Abstract

A releasable coupling enables two cylindrical cartridges (1a,1b), at least one contg. propellant explosive while the other may include a missile, to be rigidly connected together before loading into a fun barrel. The end of cartridge (1a) carries a resilient plastic ring (12) which is slidable axially forwards to engage a second ring (19) fixed to the matching end of cartridge (1b), outer lip (18) on ring (12) then latching under inward facing flange (20) on ring (19) to lock the cartridges together. The axial movement of ring (12) is restricted by an inner lip (14) thereon engaging a flange (11) on a collar (9) which slidably supports ring (12) on cartridge (1a). The outer surface of ring (12) is so shaped that as the cartridges are loaded into the barrel ring (12) is radially compressed to unhook lip (18) from flange (20), while an inner lip (16) on ring (12) is able to hook onto an outward facing flange (21) on ring (19). Should the cartridges now be withdrawn from the barrel instead of being fired, cartridge (1b) is pulled along behind cartridge (1a) but released therefrom once ring (12) comes clear of the barrel and resumes its original shape. <IMAGE>

Description

Le domaine technique de l'invention est celui des conteneurs pouvant recevoir une charge propulsive et plus particulièrement celui des conteneurs utilisés dans le domaine de l'artillerie de gros calibre ou de char.The technical field of the invention is that of containers capable of receiving a propellant charge and more particularly that of containers used in the field of large caliber or tank artillery.

Afin de régler la portée du tir, il est souvent nécessaire de modifier la quantité de poudre qui est utilisée pour lancer un projectile.In order to adjust the range of the shot, it is often necessary to change the amount of powder that is used to launch a projectile.

On a déjà défini des conteneurs modulaires sensiblement cylindriques et réalisés en matériau combustible. Grâce à leur rigidité, de tels conteneurs sont plus faciles d'emploi que les sachets de poudres traditionnels.Modular cylindrical containers which have been made of combustible material have already been defined. Thanks to their rigidity, such containers are easier to use than traditional powder sachets.

Afin de réduire l'encombrement des munitions à l'intérieur des véhicules blindés, il peut être également nécessaire de les diviser en deux parties distinctes, l'une portant le chargement propulsif principal et l'autre le projectile et éventuellement un chargement propulsif secondaire (on regardera par exemple le brevet GB2136929 qui décrit de telles munitions).In order to reduce the bulk of ammunition inside armored vehicles, it may also be necessary to divide them into two distinct parts, one carrying the main propellant charge and the other the projectile and possibly a secondary propellant charge ( we will look for example at patent GB2136929 which describes such munitions).

Dans tous les cas on pourra se poser le problème de la solidarisation de plusieurs conteneurs.In all cases, the problem of securing several containers may arise.

En effet il peut être utile d'accélérer le chargement en introduisant tous les conteneurs en une seule manoeuvre, par exemple au moyen d'un dispositif de chargement automatique.Indeed it may be useful to speed up the loading by introducing all the containers in a single maneuver, for example by means of an automatic loading device.

Il est alors indispensable d'assurer une solidarisation des conteneurs qui donne une certaine rigidité à l'assemblage.It is therefore essential to secure the containers, which gives a certain rigidity to the assembly.

De plus il peut s'avérer nécessaire de retirer rapidement la charge déjà introduite dans la chambre d'une arme, et ce retrait est rendu plus long et plus délicat par la division de la charge totale en plusieurs fardeaux.In addition it may be necessary to quickly remove the charge already introduced into the chamber of a weapon, and this removal is made longer and more delicate by dividing the total charge into several burdens.

Le brevet FR9101499 décrit un dispositif de liaison de conteneurs qui comporte d'une part une bague coulissante et d'autre part des moyens d'accrochage auto-agrippant disposés sur une face frontale du conteneur.Patent FR9101499 describes a container connecting device which comprises on the one hand a sliding ring and on the other hand hook-and-loop fastening means arranged on a front face of the container.

Un tel dispositif est complexe et coûteux à fabriquer.Such a device is complex and expensive to manufacture.

De plus il peut être nécessaire, en fonction des besoins opérationnels, de lier ou non les conteneurs. Or les moyens proposés par le brevet FR9101499 ne permettent pas un tel choix, la liaison axiale étant dans tous les cas assurée par les moyens d'accrochage.In addition it may be necessary, depending on operational needs, to tie the containers or not. However, the means proposed by patent FR9101499 do not allow such a choice, the axial connection being in all cases provided by the hooking means.

Il peut être également nécessaire de retirer rapidement de la chambre les conteneurs notamment pour remplacer le conteneur portant le système d'allumage (par exemple en cas de défaillance du système d'allumage). Il est nécessaire alors de faciliter une désolidarisation rapide des conteneurs lors de leur retrait de la chambre.It may also be necessary to quickly remove the containers from the chamber, in particular to replace the container carrying the ignition system (for example in the event of failure of the ignition system). It is therefore necessary to facilitate rapid separation of the containers when they are removed from the chamber.

Enfin, les moyens proposés sont de mise en oeuvre délicate. En effet, pour que la bague puisse coulisser il est nécessaire que le positionnement radial des deux conteneurs soit correct. Or les moyens d'accrochage sont actifs quelle que soit la position radiale relative des deux conteneurs. Il en résulte une difficulté pour positionner, puis rendre solidaire les deux conteneurs.Finally, the means proposed are delicate to implement. Indeed, for the ring to slide it is necessary that the radial positioning of the two containers is correct. However, the attachment means are active whatever the relative radial position of the two containers. This results in a difficulty in positioning and then making the two containers integral.

Le brevet FR1291315 décrit un accouplement détachable pour des cartouches explosives dont la désolidarisation s'effectue grâce à un fil ou un cordon qui permet de comprimer manuellement un anneau élastique interne.The patent FR1291315 describes a detachable coupling for explosive cartridges, the separation of which is effected by means of a wire or a cord which makes it possible to manually compress an internal elastic ring.

Un tel dispositif n'est pas satisfaisant du point de vue opérationnel car la désolidarisation des cartouches nécessite un élément supplémentaire extérieur à la cartouche (fil ou cordon). De plus, une telle désolidarisation n'est pas rapide.Such a device is not satisfactory from an operational point of view because the separation of the cartridges requires an additional element external to the cartridge (wire or cord). In addition, such a separation is not rapid.

C'est le but de la présente invention que de proposer un dispositif de liaison de conteneurs qui ne présente pas de tels inconvénients.It is the object of the present invention to provide a container connecting device which does not have such drawbacks.

L'invention propose ainsi un dispositif de liaison de conteneurs qui est simple et bon marché. Ce dispositif permet d'assurer une liaison facile de deux conteneurs avant leur introduction dans la chambre d'une arme et une désolidarisation rapide des conteneurs sans utiliser un élément supplémentaire, lorsqu'il est nécessaire de les retirer de la chambre.The invention thus provides a container connection device which is simple and inexpensive. This device ensures easy connection of two containers before their introduction into the chamber of a weapon and rapid separation of the containers without using an additional element, when it is necessary to remove them from the chamber.

L'invention a également pour objet un conteneur pouvant être rendu solidaire d'un autre conteneur au niveau d'une de ses faces frontales, au moyen d'un tel dispositif de liaison.The invention also relates to a container which can be made integral with another container at one of its front faces, by means of such a connecting device.

L'invention peut s'appliquer aussi bien à la réalisation de charges modulaires que de chargements en au moins deux fardeaux, l'un portant la charge principale et son tube allumeur et l'autre le projectile (et éventuellement, mais non obligatoirement, une charge secondaire).The invention can be applied as well to the realization of modular loads as of loads in at least two loads, one carrying the main load and its igniter tube and the other the projectile (and possibly, but not necessarily, a secondary charge).

Ainsi l'invention a pour objet un dispositif permettant de solidariser deux conteneurs au niveau de leurs faces frontales et comprenant une bague montée de façon coulissante au niveau d'un premier rétreint aménagé sur un premier conteneur et pouvant coulisser pour venir recouvrir partiellement un deuxième rétreint aménagé sur un deuxième conteneur, l'extrémité avant de la bague comportant un bec annulaire qui assure un accrochage axial de la bague sur le deuxième conteneur lorsqu'elle vient recouvrir le deuxième rétreint, le bec coopérant avec un redent circulaire porté par un anneau solidaire du deuxième rétreint, dispositif caractérisé en ce qu'il comporte des premiers moyens assurant le décrochage de l'extrémité avant de la bague d'avec le deuxième conteneur lorsque les deux conteneurs sont mis en place dans une chambre d'une arme, moyens qui comprennent un diamètre externe de la bague supérieur au diamètre externe du conteneur, la bague étant susceptible de se déformer radialement, lorsqu'elle est mise dans la chambre de l'arme, de façon à adopter un diamètre sensiblement égal à celui du conteneur, cette déformation provoquant le décrochage du bec annulaire de la bague d'avec le redent circulaire de l'anneau du deuxième conteneur lorsque les deux conteneurs sont en place dans la chambre de l'arme.Thus, the subject of the invention is a device making it possible to secure two containers at their front faces and comprising a ring mounted in a sliding manner at the level of a first constriction arranged on a first container and which can slide to partially cover a second constriction fitted on a second container, the front end of the ring comprising an annular spout which ensures an axial attachment of the ring on the second container when it comes to cover the second constriction, the spout cooperating with a circular redent carried by a solid ring of the second constriction, a device characterized in that it comprises first means ensuring the detachment of the front end of the ring from the second container when the two containers are placed in a chamber of a weapon, means which include an outer diameter of the ring greater than the outer diameter of the container, the ring being susceptible e to deform radially, when it is placed in the chamber of the weapon, so as to adopt a diameter substantially equal to that of the container, this deformation causing the annular beak of the ring to come off with the circular redent of the ring of the second container when the two containers are in place in the chamber of the weapon.

Avantageusement, le dispositif comporte des deuxièmes moyens assurant l'accrochage d'une partie interne de la bague avec le deuxième conteneur lorsque les deux conteneurs se trouvent dans la chambre de l'arme.Advantageously, the device comprises second means ensuring the attachment of an internal part of the ring with the second container when the two containers are in the chamber of the weapon.

Préférentiellement, les deuxièmes moyens d'accrochage de la partie interne de la bague comportent un repli aménagé sur la surface interne de cette dernière et susceptible de venir en butée sur une collerette portée par l'anneau solidaire du deuxième rétreint.Preferably, the second attachment means of the internal part of the ring comprise a fold arranged on the internal surface of the latter and capable of coming into abutment on a flange carried by the ring secured to the second constriction.

La bague comportera, au niveau d'une partie arrière, un épaulement destiné à coopérer avec un collet aménagé sur le premier rétreint afin de réaliser une butée axiale et sera réalisée en une matière plastique du type Polyoxyméthylène ou Polyéthylène Haute densité ou polyamide.The ring will include, at a rear part, a shoulder intended to cooperate with a collar arranged on the first constriction in order to produce an axial stop and will be made of a plastic material of the Polyoxymethylene or High Density Polyethylene or polyamide type.

Le collet fera partie d'une sous-bague solidaire du premier rétreint, sous-bague sur laquelle la bague est montée de façon coulissante.The collar will be part of a sub-ring integral with the first neck, sub-ring on which the ring is slidably mounted.

La sous-bague et/ou l'anneau seront réalisée en une matière plastique du type Polyéthylène Haute densité ou polyamide.The sub-ring and / or the ring will be made of a plastic material of the High Density Polyethylene or polyamide type.

Selon un deuxième mode de réalisation, la sous-bague comportera une butée annulaire permettant la liaison axiale de la bague avec la sous-bague dans sa position avancée, l'épaulement de la bague étant positionné entre la butée et le collet annulaire.According to a second embodiment, the sub-ring will include an annular stop allowing the axial connection of the ring with the sub-ring in its advanced position, the shoulder of the ring being positioned between the stop and the annular collar.

En variante, le repli et la collerette comporteront chacun une portée conique, les deux portées coniques étant complémentaires et destinées à coopérer.As a variant, the fold and the flange will each have a conical bearing, the two conical bearing being complementary and intended to cooperate.

L'invention a également pour objet un conteneur, en particulier pour un chargement propulsif, destiné à être rendu solidaire d'un deuxième conteneur au niveau d'une de ses faces frontales par un dispositif de solidarisation, conteneur caractérisé en ce qu'il comporte au moins un rétreint aménagé au voisinage de la face frontale, rétreint destiné à recevoir une bague de diamètre externe supérieur au diamètre externe du conteneur et qui est susceptible de se déformer radialement de façon à adopter un diamètre sensiblement égal à celui du conteneur, la bague étant montée coulissante au niveau du rétreint, I'extrémité avant de la bague comportant un bec annulaire destiné à coopérer avec un redent circulaire aménagé sur un anneau.The invention also relates to a container, in particular for a propellant charge, intended to be made integral with a second container at one of its front faces by a securing device, container characterized in that it comprises at least one constriction arranged in the vicinity of the front face, constriction intended to receive a ring of external diameter greater than the external diameter of the container and which is liable to deform radially so as to adopt a diameter substantially equal to that of the container, the ring being slidably mounted at the constriction, the front end of the ring comprising an annular spout intended to cooperate with a circular step arranged on a ring.

Le rétreint comportera une sous-bague destinée à recevoir la bague, sous-bague comportant un collet annulaire destiné à coopérer avec un épaulement de la bague.The constriction will include a sub-ring intended to receive the ring, sub-ring comprising an annular collar intended to cooperate with a shoulder of the ring.

Selon une autre caractéristique, le conteneur comporte au moins un rétreint aménagé au voisinage de la face frontale, rétreint destiné à recevoir un anneau présentant un redent circulaire destiné à coopérer avec un bec annulaire aménagé sur une bague portée par le deuxième conteneur.According to another characteristic, the container comprises at least one constriction arranged in the vicinity of the front face, constricted intended to receive a ring having a circular redent intended to cooperate with an annular spout arranged on a ring carried by the second container.

En se reportant à la figure 1, un premier conteneur la est destiné à être rendu solidaire d'un deuxième conteneur 1b au niveau de sa face frontale 2a. Cette dernière sera alors en contact avec la face frontale 2b du deuxième conteneur.Referring to Figure 1, a first container 1a is intended to be made integral with a second container 1b at its front face 2a. The latter will then be in contact with the front face 2b of the second container.

Chaque conteneur comporte une enveloppe cylindrique 3a, 3b réalisée en un matériau combustible tel de la nitrocellulose, du carton ou un mélange carton/nitrocellulose.Each container comprises a cylindrical envelope 3a, 3b made of a combustible material such as nitrocellulose, cardboard or a cardboard / nitrocellulose mixture.

Les enveloppes sont fermées par des bouchons d'extrémité 4a, 4b qui sont également réalisés en un matériau combustible. Les bouchons sont rendus solidaires des enveloppes par collage au niveau des portées cylindriques 5a, 5b.The envelopes are closed by end caps 4a, 4b which are also made of a combustible material. The caps are made integral with the envelopes by gluing at the level of the cylindrical surfaces 5a, 5b.

Les conteneurs 1a et 1b sont représentés ici de façon partielle. Ils sont destinés à recevoir une charge propulsive en grains ou en sticks (non représentée).The containers 1a and 1b are shown here partially. They are intended to receive a propellant charge in grains or sticks (not shown).

Le conteneur 1b porte à son autre extrémité un projectile (non représenté) qui sera rendu solidaire de l'enveloppe 3b par une bague de liaison (par exemple semblable à celle décrite par le brevet FR8712484).The container 1b carries at its other end a projectile (not shown) which will be made integral with the casing 3b by a connecting ring (for example similar to that described by patent FR8712484).

Le conteneur la porte à son autre extrémité un culot (non représenté) doté d'un tube allumeur (voir par exemple le brevet FR9101499 qui montre la fixation d'un tel culot sur l'enveloppe).The container carries at its other end a base (not shown) provided with an igniter tube (see for example patent FR9101499 which shows the fixing of such a base on the envelope).

Il serait possible également de fixer le projectile sur le conteneur 1a et 1e culot sur le conteneur 1b.It would also be possible to fix the projectile on the container 1a and the base on the container 1b.

Le bouchon 4b porte une cuvette 6 à profil tronconique qui est placé au centre de la face frontale 2b.The stopper 4b carries a cup 6 with a frustoconical profile which is placed in the center of the front face 2b.

Le bouchon porte un renflement 7 à profil tronconique qui est placé au centre de la face frontale 2a.The stopper carries a bulge 7 with a frustoconical profile which is placed in the center of the front face 2a.

Les profils tronconiques de la cuvette 6 et du renflement 7 sont complémentaires et sont destinés à coopérer l'un avec l'autre pour permettre un positionnement radial relatif des deux conteneurs avant leur assemblage.The frustoconical profiles of the bowl 6 and the bulge 7 are complementary and are intended to cooperate with each other to allow relative radial positioning of the two containers before their assembly.

Des ouvertures axiales 22a et 22b sont aménagées au niveau des faces frontales 2a et 2b des conteneurs. Ces ouvertures permettent de faciliter la transmission de flamme d'un conteneur à un autre lors de la mise à feu de la charge propulsive. Elles sont obstruées, d'une façon connue, par exemple au moyen de feuilles combustibles (non représentées).Axial openings 22a and 22b are arranged at the front faces 2a and 2b of the containers. These openings facilitate the transmission of flame from one container to another when igniting the propellant charge. They are obstructed, in a known manner, for example by means of combustible sheets (not shown).

Les bouchons d'extrémité 4a et 4b portent chacun un rétreint 8a, 8b dont le diamètre maximal D1 est inférieur de l'ordre de 10 mm au diamètre externe D2 du conteneur, le diamètre D2 du conteneur correspondant sensiblement au diamètre interne d'une chambre d'une arme dans laquelle il sera mis en place.The end plugs 4a and 4b each carry a constriction 8a, 8b, the maximum diameter D1 of which is less by the order of 10 mm than the external diameter D2 of the container, the diameter D2 of the container corresponding substantially to the internal diameter of a chamber. of a weapon in which it will be placed.

Le rétreint 8a du conteneur la porte une sous-bague 9 fixée par exemple par collage. Cette sous-bague est réalisée en matière plastique par exemple du type Polyéthylène Haute densité ou polyamide.The constriction 8a of the container carries it a sub-ring 9 fixed for example by gluing. This sub-ring is made of plastic, for example of the high density polyethylene or polyamide type.

La sous-bague 9 porte sur sa surface cylindrique externe 10 un collet annulaire 11.The sub-ring 9 carries on its external cylindrical surface 10 an annular collar 11.

Une bague 12 est montée de façon coulissante sur la sous-bague 9. Elle est également réalisée en matière plastique du type Polyoxyméthylène ou Polyéthylène Haute densité ou polyamide. Elle comporte un épaulement 14 aménagé au niveau d'une partie arrière 13 et un repli 16 au niveau d'une surface interne et du côté d'une extrémité avant 15.A ring 12 is slidably mounted on the sub-ring 9. It is also made of plastic material of the polyoxymethylene or high density polyethylene or polyamide type. It has a shoulder 14 arranged at a rear part 13 and a fold 16 at an internal surface and on the side of a front end 15.

L'épaulement 14 et le repli 16 ont un diamètre supérieur au diamètre externe 10 de la sous-bague 9, ce qui autorise le coulissement de la bague sur la sous-bague.The shoulder 14 and the fold 16 have a diameter greater than the external diameter 10 of the sub-ring 9, which allows the sliding of the ring on the sub-ring.

L'épaulement 14 est destiné à venir en butée sur le collet annulaire 11 de façon à limiter le déplacement axial de la bague 12 par rapport à la sous-bague 9.The shoulder 14 is intended to abut on the annular collar 11 so as to limit the axial displacement of the ring 12 relative to the sub-ring 9.

Du point de vue montage, la bague 12 est mise en place par élasticité sur la sous-bague avant de coller cette dernière sur le rétreint 8a. Ainsi la bague 12 ne peut plus être séparée du conteneur 1a, ce qui évite sa perte et simplifie la logistique. On pourra prévoir, afin de faciliter la mise en place de la bague sur la sous-bague, un chanfrein de montage sur la face arrière de l'épaulement 14 de la bague et sur la face avant du collet annulaire 11 de la sous-bague.From the mounting point of view, the ring 12 is put in place by elasticity on the sub-ring before gluing the latter on the neck 8a. Thus the ring 12 can no longer be separated from the container 1a, which avoids its loss and simplifies the logistics. In order to facilitate the positioning of the ring on the sub-ring, provision may be made for a mounting chamfer on the rear face of the shoulder 14 of the ring and on the front face of the annular collar 11 of the sub-ring. .

La bague 12 comporte un bourrelet externe 17 de diamètre D3 qui est supérieur au diamètre D2 du conteneur de l'ordre de 2 à 3 mm.The ring 12 comprises an outer bead 17 of diameter D3 which is greater than the diameter D2 of the container of the order of 2 to 3 mm.

La bague comporte également, au niveau de son extrémité avant 15, un bec annulaire 18.The ring also includes, at its front end 15, an annular spout 18.

Le conteneur 1b porte sur son rétreint 8b un anneau 19 fixé par exemple par collage. Cet anneau est lui aussi réalisé en matière plastique par exemple du type Polyéthylène Haute densité ou polyamide.The container 1b carries on its neck 8b a ring 19 fixed for example by gluing. This ring is also made of plastic, for example of the high density polyethylene or polyamide type.

L'anneau 19 porte un redent circulaire 20 destiné à coopérer avec le bec annulaire 18 de la bague 12. Il comporte également une collerette 21 destinée à coopérer avec le repli 16 de la bague 12.The ring 19 carries a circular redent 20 intended to cooperate with the annular spout 18 of the ring 12. It also includes a flange 21 intended to cooperate with the fold 16 of the ring 12.

La figure 2 représente les deux conteneurs 1a et 1b assemblés par la bague 12.FIG. 2 represents the two containers 1a and 1b assembled by the ring 12.

Les deux conteneurs ont été mis en contact l'un avec l'autre au niveau de leurs faces frontales 2a, 2b. La cuvette 6 et le renflement 7 assurent alors l'alignement des conteneurs et constituent ainsi des moyens assurant un bon positionnement radial des deux conteneurs.The two containers were brought into contact with each other at their end faces 2a, 2b. The bowl 6 and the bulge 7 then ensure the alignment of the containers and thus constitute means ensuring good radial positioning of the two containers.

Une fois les deux conteneurs positionnés l'un par rapport à l'autre, on fait coulisser la bague 12 sur la sous-bague 9 de façon à l'amener en contact avec l'anneau 19. Un léger forcement permet d'accrocher le bec annulaire 18 au redent circulaire 20, ce qui permet d'assurer la solidarisation des deux conteneurs.Once the two containers have been positioned relative to each other, the ring 12 is slid over the sub-ring 9 so as to bring it into contact with the ring 19. A slight forcing makes it possible to hang the annular spout 18 with circular redent 20, which ensures the securing of the two containers.

L'épaulement 14 de la bague 12 se retrouve alors en butée contre le collet annulaire 11 de la sous-bague 9. Le collet 11 assure ainsi l'immobilisation axiale des conteneurs 1A et 1b lorsque le bec 18 de la bague 12 est accroché au redent circulaire 20 de l'anneau 19.The shoulder 14 of the ring 12 is then found in abutment against the annular collar 11 of the sub-ring 9. The collar 11 thus ensures the axial immobilization of the containers 1A and 1b when the spout 18 of the ring 12 is hooked to the circular redent 20 of the ring 19.

Les dimensions de la bague, de la sous-bague et de l'anneau seront définies de telle sorte que cette immobilisation axiale puisse être réalisée. Ainsi, lorsque les conteneurs sont en contact au niveau de leurs faces frontales et que le bec 18 se trouve accroché au redent 20, l'épaulement 14 est en butée contre le collet 11.The dimensions of the ring, the sub-ring and the ring will be defined so that this axial immobilization can be achieved. Thus, when the containers are in contact at their front faces and the spout 18 is hooked to the redent 20, the shoulder 14 is in abutment against the collar 11.

La collerette 21 présente un diamètre externe sensiblement inférieur au diamètre externe 10 de la sous-bague 9 afin de ne pas interférer avec le repli 16 lors de la translation de la bague 12.The flange 21 has an external diameter substantially smaller than the external diameter 10 of the sub-ring 9 so as not to interfere with the fold 16 during the translation of the ring 12.

Le matériau constitutif de la bague, de la sous-bague et de l'anneau se fragmente lors de la mise à feu de la charge propulsive sous l'effet de la pression des gaz. Afin de faciliter la fragmentation on pourra prévoir des zones de fragilisation, obtenues par exemple par des échauffements localisés ou des usinages.The material of the ring, the sub-ring and the ring fragments when the propellant charge is ignited under the effect of the gas pressure. In order to facilitate fragmentation, it is possible to provide zones of embrittlement, obtained for example by localized heating or machining.

L'emploi de matières plastiques pour réaliser bague, sous-bague et anneau permet de définir des conteneurs dont la liaison est extrêmement rigide.The use of plastics to produce rings, sub-rings and rings makes it possible to define containers whose connection is extremely rigid.

La figure 3 représente les deux conteneurs 1a et 1b assemblés par la bague 12 et mis en place à l'intérieur d'un tube 23 d'une arme.FIG. 3 represents the two containers 1a and 1b assembled by the ring 12 and placed inside a tube 23 of a weapon.

Lors du chargement des deux conteneurs 1a et 1b à l'intérieur d'une chambre 24 du tube 23 suivant la flèche C, la bague 12, qui présente en position repos un diamètre D3 supérieur au diamètre D2 des conteneurs, se déforme radialement de manière élastique afin d'adopter le diamètre interne de la chambre 24.When loading the two containers 1a and 1b inside a chamber 24 of the tube 23 along arrow C, the ring 12, which in the rest position has a diameter D3 greater than the diameter D2 of the containers, deforms radially elastic in order to adopt the internal diameter of the chamber 24.

La déformation de la bague entraîne le décrochement du bec 18 d'avec le redent circulaire 20 puis un léger recul de la bague par rapport aux conteneurs jusqu'à ce que le repli 16 vienne sensiblement en butée contre la collerette 21.The deformation of the ring causes the spout 18 to unhook from the circular redent 20 and then a slight recoil of the ring relative to the containers until the fold 16 comes substantially into abutment against the flange 21.

Les dimensions de la bague seront définies de telle sorte que la déformation de celle-ci par diminution de son diamètre externe D3 puisse assurer la libération de l'accrochage du bec 18 d'avec le redent 20 et l'avancée du repli 16 au voisinage de la collerette 21.The dimensions of the ring will be defined so that the deformation of the latter by reduction of its external diameter D3 can ensure the release of the attachment of the spout 18 from the redent 20 and the advancement of the fold 16 in the vicinity of the collar 21.

La figure 4 représente les deux conteneurs 1a et 1b lors de la phase de déchargement.Figure 4 shows the two containers 1a and 1b during the unloading phase.

Il peut s'avérer nécessaire de retirer rapidement la charge déjà introduite dans la chambre d'une arme. Ce déchargement s'effectue alors de la manière suivante:
   - On retire le conteneur la suivant la flèche DC, ce qui amène le collet 11 de la sous-bague 9 en butée contre l'épaulement 14 de la bague. Le repli 16 de la bague étant en appui contre la collerette 21 de l'anneau 19, le conteneur 1b est donc solidarisé axialement et entraîné à la suite du conteneur 1a.It may be necessary to quickly remove the charge already introduced into the chamber of a weapon. This unloading is then carried out as follows:
- The container is removed along the arrow DC, which brings the collar 11 of the sub-ring 9 into abutment against the shoulder 14 of the ring. The fold 16 of the ring being in abutment against the collar 21 of the ring 19, the container 1b is therefore secured axially and driven following the container 1a.

Ainsi les deux conteneurs peuvent être retirés ensemble en une seule opération.Thus the two containers can be removed together in a single operation.

La figure 5 représente les deux conteneurs 1a et 1b en fin de phase de déchargement.FIG. 5 represents the two containers 1a and 1b at the end of the unloading phase.

A la sortie du tube 23, lorsque l'effort de traction sur le conteneur la cesse, le conteneur 1b de part son inertie continue son mouvement vers le conteneur la, libérant ainsi la bague 12 qui reprend sa position haute initiale grâce à son élasticité rémanente en libérant le repli 16 de la collerette 21. Celà permet une désolidarisation automatique des deux conteneurs sans nécessiter d'intervention manuelle.At the outlet of the tube 23, when the tensile force on the container ceases, the container 1b due to its inertia continues its movement towards the container 1a, thus releasing the ring 12 which returns to its initial high position thanks to its remanent elasticity by releasing the fold 16 of the flange 21. This allows an automatic separation of the two containers without requiring manual intervention.

Les deux conteneurs sont ainsi retirés de la chambre du tube de l'arme en une seule opération et se retrouvent non solidaires l'un de l'autre, ce qui permet une manoeuvre plus rapide par exemple en cas d'échange d'un seul des conteneurs ou de remise en position de stockage suite à une non utilisation.The two containers are thus removed from the barrel chamber of the weapon in a single operation and are found not integral with each other, which allows faster maneuvering, for example in the event of a single exchange. containers or return to storage position after non-use.

La figure 6 représente un conteneur de type modulaire selon l'invention. Ce conteneur, réalisé en matériau combustible est destiné à être assemblé avec d'autres conteneurs qui lui sont totalement identiques afin de constituer un chargement propulsif d'artillerie.FIG. 6 represents a modular type container according to the invention. This container, made of combustible material, is intended to be assembled with other containers which are completely identical to it in order to constitute a propellant artillery charge.

Il est constitué d'une enveloppe combustible 3, fermée à une extrémité par un bouchon 4a qui porte un premier rétreint 8a et à l'autre extrémité par un bouchon 4b portant un deuxième rétreint 8b.It consists of a combustible envelope 3, closed at one end by a plug 4a which carries a first constriction 8a and at the other end by a plug 4b carrying a second constriction 8b.

Le premier rétreint 8a porte une sous-bague 9 et une bague 12. Le deuxième rétreint 8b porte un anneau 19.The first constriction 8a carries a sub-ring 9 and a ring 12. The second constriction 8b carries a ring 19.

Il serait évidemment possible de définir un conteneur modulaire dont les faces frontales comporteraient des moyens de positionnement radial constitués par une cuvette ou un renflement.It would obviously be possible to define a modular container, the front faces of which would include radial positioning means constituted by a bowl or a bulge.

L'enveloppe serait alors fermée à ses extrémités par des bouchons 4a, 4b du type de ceux représentés à la figure 1.The envelope would then be closed at its ends by plugs 4a, 4b of the type of those shown in FIG. 1.

Dans le mode de réalisation des conteneurs précédemment décrit, l'enveloppe cylindrique était fermée par deux bouchons combustibles portant un rétreint . Il sera possible à titre de variante de réaliser au moins un bouchon d'une seule et même pièce avec l'enveloppe. On procède pour celà à une mise en forme de l'enveloppe dans un moule approprié. On évite ainsi une opération délicate de fixation par collage du bouchon sur l'enveloppe.In the embodiment of the containers described above, the cylindrical envelope was closed by two combustible plugs carrying a constriction. As a variant, it will be possible to produce at least one stopper in one and the same piece with the envelope. For this, the envelope is shaped in an appropriate mold. This avoids a delicate operation of fixing by gluing the plug on the envelope.

Il sera également possible de réaliser des bouchons en matière plastique et formant une seule et même pièce avec l'anneau ou la sous-bague. Il suffit pour définir cette variante de reprendre les figures déjà décrites et de considérer sur ces figures que bouchon et anneau ou bouchon et sous-bague constituent une seule et même pièce.It will also be possible to make plastic plugs and forming a single piece with the ring or the sub-ring. To define this variant, it suffices to use the figures already described and to consider in these figures that the plug and ring or the plug and sub-ring constitute a single piece.

Afin de faciliter la fragmentation de tels bouchons en matière plastique, on pourra prévoir sur ces derniers des zones de fragilisation, obtenues par exemple par des échauffements localisés ou par des usinages.In order to facilitate the fragmentation of such plastic plugs, weakening zones may be provided on the latter, obtained for example by localized heating or by machining.

La figure 7 représente deux conteneurs selon un deuxième mode de réalisation.Figure 7 shows two containers according to a second embodiment.

Dans ce mode de réalisation, la sous bague 9 présente sur sa surface cylindrique externe 10 et à proximité du collet 11, une butée annulaire 25.In this embodiment, the sub-ring 9 has on its external cylindrical surface 10 and near the collar 11, an annular stop 25.

La butée 25 permet le maintien axial de la bague 12 lorsque celle-ci est en position avancée, l'épaulement 14 de la bague étant venu se loger entre le collet 11 et la butée 25.The stop 25 allows the axial retention of the ring 12 when the latter is in the advanced position, the shoulder 14 of the ring having come to be received between the collar 11 and the stop 25.

La butée 25 présente un chanfrein à sa partie arrière qui facilite le passage de la bague 12. La bague peut également porter un chanfrein complémentaire (non représentée) sur la partie avant de l'épaulement 14.The stop 25 has a chamfer at its rear part which facilitates the passage of the ring 12. The ring can also carry a complementary chamfer (not shown) on the front part of the shoulder 14.

Un tel mode de réalisation présente l'avantage de pouvoir être utilisé dans un dispositif de chargement automatique sans nécessiter l'assemblage préalable des deux conteneurs, seul est nécessaire la translation de la bague 12 en position avancée. En effet, la bague étant dans sa position avancée, le conteneur la est mis en place dans le chargement automatique suivi du conteneur 1b. La bague 12 ne pouvant pas reculer grâce à la butée 25, le conteneur 1b vient se solidariser automatiquement au conteneur la par accrochage du bec 18 de la bague 12 sur le redent 20 de l'anneau 19.Such an embodiment has the advantage of being able to be used in an automatic loading device without requiring the prior assembly of the two containers, only the translation of the ring 12 in the advanced position is necessary. Indeed, the ring being in its advanced position, the container la is put in place in the automatic loading followed by the container 1b. The ring 12 being unable to move back thanks to the stop 25, the container 1b is automatically joined to the container by hooking the spout 18 of the ring 12 on the redent 20 of the ring 19.

La collerette 21 de l'anneau 19 présente, dans ce deuxième mode de réalisation, une portée conique 26 complémentaire d'une portée conique 27 réalisée au niveau arrière du repli 16 de la bague 12.The collar 21 of the ring 19 has, in this second embodiment, a conical bearing 26 complementary to a conical bearing 27 produced at the rear level of the fold 16 of the ring 12.

Les deux portées coniques complémentaires 26 et 27 améliorent la tenue mécanique de la liaison repli 16/collerette 21 lors du retrait des conteneurs. Elles permettent de maintenir la liaison lors du retrait tant que l'effort de traction est effectif.The two complementary conical bearing surfaces 26 and 27 improve the mechanical strength of the fold back link 16 / flange 21 when the containers are removed. They allow the connection to be maintained during removal as long as the tractive effort is effective.

Bien entendu, en variante, il est possible de prévoir pour le premier mode de réalisation, une collerette 21 et un repli 16 présentant chacun une portée conique complémentaire 26, 27, comme il est également possible de ne prévoir aucune portée conique pour le deuxième mode de réalisation de l'invention.Of course, as a variant, it is possible to provide for the first embodiment, a flange 21 and a fold 16 each having a complementary conical bearing 26, 27, as it is also possible to provide no conical bearing for the second mode for carrying out the invention.
