Description

Le domaine de la présente 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 field of the present 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 separate 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 le partage 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 EP341270 propose des conteneurs entièrement symétriques et comportant des rétreints aménagés à chacune de leurs extrémités. Il est possible de solidariser deux ou plusieurs conteneurs au moyen d'une bague dont la longueur est sensiblement égale au double de la longueur des rétreints.Patent EP341270 proposes containers that are entirely symmetrical and that contain constrictions arranged at each of their ends. It is possible to secure two or more containers by means of a ring whose length is substantially equal to twice the length of the necks.

Cette disposition présente un certain nombre d'inconvénients. Ainsi la réalisation de l'assemblage est compliquée par le fait qu'il est nécessaire de mettre la bague en place sur un des conteneurs avant de positionner le deuxième conteneur dans la bague.This arrangement has a number of drawbacks. Thus the production of the assembly is complicated by the fact that it is necessary to put the ring in place on one of the containers before positioning the second container in the ring.

En effet, la bague ne peut pas être laissée à demeure sur le conteneur car en restant sur le conteneur d'extrémité (côté projectile), elle augmenterait inutilement l'encombrement total du chargement. Elle risquerait en plus d'être détériorée au cours des manipulations.Indeed, the ring cannot be left permanently on the container because by remaining on the end container (projectile side), it would unnecessarily increase the total size of the load. It could also be damaged during handling.

De plus la rigidité de l'assemblage dépend essentiellement de la valeur du serrage de la bague sur les rétreints, ce serrage dépendant lui même de l'amplitude de la déformation de la surface latérale du rétreint par la bague qui porte des renflements.In addition, the rigidity of the assembly essentially depends on the value of the tightening of the ring on the necks, this tightening itself depending on the amplitude of the deformation of the lateral surface of the necking by the ring which carries bulges.

Une telle configuration n'est pas adaptée à des charges dont la masse peut être de l'ordre de la dizaine de DaN (cas des charges pour munitions de char).Such a configuration is not suitable for loads whose mass can be of the order of ten DaN (case of charges for tank ammunition).

Les charges risquent ainsi de ne pas se trouver alignées axialement ce qui peut causer des incidents au moment de l'introduction de l'assemblage dans la chambre surtout si ce dernier est effectué par un chargeur automatique.The loads thus risk not being axially aligned which can cause incidents when the assembly is introduced into the chamber, especially if the latter is carried out by an automatic charger.

C'est le but de la présente invention que de proposer un conteneur pouvant s'assembler facilement et rapidement avec d'autres conteneurs.It is the object of the present invention to provide a container that can be easily and quickly assembled with other containers.

L'invention s'applique ainsi 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 thus applies 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 conteneur, en particulier pour un chargement propulsif, et qui est destiné à être rendu solidaire d'un autre conteneur au niveau d'une de ses faces frontales, ce conteneur est caractérisé en ce que les moyens de solidarisation comportent d'une part une bague disposée sur un rétreint aménagé au niveau d'une extrémité du conteneur, bague susceptible de coulisser suivant une direction axiale pour venir recouvrir un deuxième rétreint aménagé sur l'autre conteneur, et d'autre part des moyens d'accrochage disposés sur l'un et/ou l'autre conteneur au niveau des faces frontales destinées à venir en contact mutuel.Thus the subject of the invention is a container, in particular for a propellant charge, and which is intended to be made integral with another container at one of its front faces, this container is characterized in that the means for securing on the one hand comprise a ring arranged on a constriction arranged at one end of the container, a ring capable of sliding in an axial direction to cover a second constriction fitted on the other container, and on the other hand hooking means arranged on one and / or the other container at the level of the front faces intended to come into mutual contact.

La bague assure l'alignement des conteneurs ainsi que la rigidité à la flexion de l'assemblage. Les moyens d'accrochage assurent la liaison axiale des conteneurs.The ring ensures the alignment of the containers as well as the bending stiffness of the assembly. The attachment means ensure the axial connection of the containers.

La bague améliore également la tenue des moyens d'accrochage en leur évitant toute contrainte de cisaillement.The ring also improves the resistance of the fastening means by preventing them from any shear stress.

Selon une autre caractéristique, la bague peut occuper une première position dans laquelle elle se trouve en retrait relativement à la face frontale considérée du conteneur ainsi qu'une deuxième position dans laquelle elle dépasse de cette face frontale.According to another characteristic, the ring can occupy a first position in which it is set back relative to the front face considered of the container as well as a second position in which it protrudes from this front face.

On évite ainsi les détériorations de la bague qui peut alors être laissée à demeure sur le conteneur.This prevents damage to the ring which can then be left permanently on the container.

Selon une autre caractéristique, des moyens de verrouillage axial de la position de la bague relativement au conteneur sont prévus.According to another characteristic, means for axially locking the position of the ring relative to the container are provided.

Ces moyens de verrouillage pourront comprendre au moins deux lames élastiques, solidaires du conteneur au niveau de génératrices du rétreint portant la bague et régulièrement réparties angulairement relativement au conteneur, ces lames étant susceptibles de venir former une butée immobilisant la bague dans sa deuxième position.These locking means may comprise at least two elastic blades, integral with the container at the level of generators of the constriction carrying the ring and regularly distributed angularly relative to the container, these blades being capable of coming to form a stop immobilizing the ring in its second position.

De façon avantageuse, la bague comporte des lumières dans lesquelles viennent les lames élastiques lorsque la bague est dans sa première position.Advantageously, the ring has openings in which the elastic blades come when the ring is in its first position.

Selon un mode particulier de réalisation, les moyens d'accrochage comprennent des éléments auto-agrippant.According to a particular embodiment, the attachment means comprise hook-and-loop elements.

Le conteneur selon l'invention pourra être de type modulaire, dans ce cas il présente un rétreint à chacune de ses extrémités, les rétreints étant de longueurs différentes et la bague étant disposée sur le rétreint le plus long.The container according to the invention may be of the modular type, in this case it has a constriction at each of its ends, the constrictions being of different lengths and the ring being disposed on the longest constriction.

Dans ce dernier cas il sera avantageux de prévoir un élément auto-agrippant disposé sur une face frontale et un deuxième élément auto-agrippant de type complémentaire disposé sur la deuxième face frontale.In the latter case, it will be advantageous to provide a self-gripping element arranged on a front face and a second self-gripping element of complementary type disposed on the second front face.

Le conteneur selon l'invention pourra aussi constituer le conteneur de base ou bien le conteneur porte-projectile d'un chargement en au moins deux fardeaux.The container according to the invention may also constitute the basic container or else the projectile-carrying container for a load in at least two loads.

L'invention sera mieux comprise à la lecture de la description de modes particuliers de réalisation, description faite en référence aux dessins annexés dans lesquels:The invention will be better understood on reading the description of particular embodiments, description made with reference to the accompanying drawings in which:

Les figures 1 et 2 représentent les extrémités relatives de deux conteneurs selon l'invention avant et après leur solidarisation.Figures 1 and 2 show the relative ends of two containers according to the invention before and after their joining.

La figure 3 représente un conteneur de type modulaire selon l'invention.FIG. 3 represents a modular type container according to the invention.

La figure 4 représente un chargement en deux fardeaux comprenant un conteneur de base et un conteneur porte projectile selon l'invention.FIG. 4 represents a load in two bundles comprising a basic container and a projectile container according to the invention.

En se reportant à la figure 1, une extrémité d'un conteneur 1 selon l'invention est représentée schématiquement et partiellement. Ce conteneur est réalisé de façon connue en un matériau combustible tel de la nitrocellulose ou bien du carton, il contient une charge propulsive en grain ou en sticks non représentée ici, ainsi qu'éventuellement une ou plusieurs compositions d'allumage.Referring to Figure 1, one end of a container 1 according to the invention is shown schematically and partially. This container is produced in a known manner from a combustible material such as nitrocellulose or else cardboard, it contains a propellant charge in grain or in sticks not shown here, as well as possibly one or more ignition compositions.

Un rétreint 5 est aménagé au niveau de cette extrémité et il porte une bague 2 réalisée également en un matériau combustible. Pour faciliter la description la bague est représentée coupée sur la moitié gauche de cette figure 1.A constriction 5 is arranged at this end and it carries a ring 2 also made of a combustible material. To facilitate the description, the ring is shown cut on the left half of this figure 1.

Le diamètre externe de la bague est sensiblement égal à celui du conteneur lui-même.The outer diameter of the ring is substantially equal to that of the container itself.

Un certain nombre de lames élastiques 9, réalisées par exemple en acier à ressort, sont rendues solidaires du conteneur par exemple par rivetage au niveau de génératrices du rétreint 5.A certain number of elastic blades 9, made for example of spring steel, are made integral with the container for example by riveting at the level of generatrices of the constriction 5.

Ces lames sont régulièrement réparties angulairement relativement au conteneur et elles viennent dans des lumières 10 réalisées sur la bague 2.These blades are regularly distributed angularly relative to the container and they come in slots 10 made on the ring 2.

La bague peut coulisser relativement au conteneur 1 suivant la direction axiale XX′. L'élasticité des lames 9 maintient la bague dans sa première position telle que représentée sur la figure 1, c'est à dire en butée sur l'épaulement 7 qui sépare le rétreint 5 du corps du conteneur 1.The ring can slide relative to the container 1 in the axial direction XX ′. The elasticity of the blades 9 keeps the ring in its first position such that represented in FIG. 1, that is to say in abutment on the shoulder 7 which separates the constriction 5 from the body of the container 1.

La face frontale 3 du conteneur porte dans le mode particulier de réalisation qui est décrit ici un moyen d'accrochage 4 qui sera par exemple un papier adhésif.The front face 3 of the container carries in the particular embodiment which is described here an attachment means 4 which will be for example an adhesive paper.

La bague 2 et les moyens d'accrochage 4 constituent des moyens permettant la solidarisation de ce premier conteneur avec un autre conteneur semblable ou non au premier.The ring 2 and the hooking means 4 constitute means allowing the first container to be secured with another container similar or not to the first.

Dans sa première position représentée figure 1, la bague se trouve en retrait relativement à la face frontale 4 du conteneur 1, une telle disposition présente l'avantage d'empêcher les détériorations de la bague consécutivement aux manipulations du conteneur.In its first position shown in FIG. 1, the ring is set back relative to the front face 4 of the container 1, such an arrangement has the advantage of preventing damage to the ring following handling of the container.

La figure 2 montre le conteneur 1 précédent assemblé à un autre conteneur 1a par l'intermédiaire des moyens de solidarisation décrits précédemment.FIG. 2 shows the previous container 1 assembled with another container 1a by means of the fastening means described above.

La bague occupe une deuxième position dans laquelle elle dépasse de la face frontale 3 (représentée en pointillés).The ring occupies a second position in which it protrudes from the front face 3 (shown in dotted lines).

Elle vient ainsi recouvrir un deuxième rétreint aménagé sur l'autre conteneur 1a et vient en butée sur un épaulement 8 de ce dernier.It thus covers a second constriction arranged on the other container 1a and abuts on a shoulder 8 of the latter.

La face frontale 3 du conteneur 1 est en contact avec la face frontale du conteneur 1a, les moyens d'accrochage se trouvent entre ces deux faces et assurent la liaison axiale des deux conteneurs.The front face 3 of the container 1 is in contact with the front face of the container 1a, the attachment means are located between these two faces and ensure the axial connection of the two containers.

Il est alors possible d'extraire l'ensemble constitué par les deux conteneurs de la chambre d'une arme.It is then possible to extract the assembly constituted by the two containers from the chamber of a weapon.

La bague en étant en contact avec les rétreints des deux conteneurs assure la rigidité à la flexion de l'assemblage et améliore également la tenue des moyens d'accrochage en leur évitant toute contrainte de cisaillement.The ring being in contact with the constrictions of the two containers ensures the bending rigidity of the assembly and also improves the resistance of the fastening means by preventing them from any shear stress.

La bague ne participe pas directement à l'accrochage axial des conteneurs, on évite ainsi les défauts d'alignement qui se rencontrent dans le système selon l'état de la technique dans lequel une bague réalise des déformations ponctuelles des rétreints.The ring does not directly participate in the axial attachment of the containers, this avoids misalignments which are encountered in the system according to the state of the art in which a ring achieves punctual deformations of the constrictions.

Dans la deuxième position de bague représentée figure 2, les lames élastiques 9 viennent en appui sur la face arrière 11 de la bague. Les lames assurent ainsi un verrouillage axial de la bague dans sa deuxième position ce qui fiabilise l'assemblage.In the second ring position shown in Figure 2, the elastic blades 9 come to bear on the rear face 11 of the ring. The blades thus ensure an axial locking of the ring in its second position which makes the assembly more reliable.

De préférence les dimensions des éléments constitutifs des conteneurs et des moyens de solidarisation seront choisies de telle sorte que la bague vienne en appui sur l'épaulement 8 du deuxième conteneur 1a quand les lames 9 sont elles mêmes en appui sur la face arrière 11 de la bague. Ainsi la bague est totalement immobilisée axialement.Preferably, the dimensions of the components of the containers and of the fastening means will be chosen so that the ring comes to bear on the shoulder 8 of the second container 1a when the blades 9 are themselves in support on the rear face 11 of the Ring. Thus the ring is completely immobilized axially.

Pratiquement on constate qu'il est nécessaire que le rétreint porté par le conteneur 1a soit plus court que celui portant la bague.In practice, it is found that it is necessary for the necking carried by the container 1a to be shorter than that carrying the ring.

Il serait possible de remplacer les lames élastiques par une légère conicité relative de la bague et du rétreint porté par le deuxième conteneur 1a.It would be possible to replace the elastic blades by a slight relative taper of the ring and the constriction carried by the second container 1a.

Suivant une variante de réalisation, les moyens d'accrochage peuvent comprendre un papier adhésif porté par le deuxième conteneur 1a, le premier conteneur ne portant que la bague.According to an alternative embodiment, the attachment means may comprise an adhesive paper carried by the second container 1a, the first container carrying only the ring.

Suivant une autre variante, les moyens d'accrochage peuvent avantageusement être constitué par des élèments auto agrippants (par exemple du type Velcro (Marque déposée)), un élément étant disposé sur la face frontale du conteneur 1 et un élément du type complémentaire étant disposé sur la face frontale du conteneur 1a.According to another variant, the attachment means can advantageously be constituted by self-gripping elements (for example of the Velcro type (registered trademark)), an element being disposed on the front face of the container 1 and an element of the complementary type being disposed on the front face of the container 1a.

Dans tous les cas les moyens d'accrochage présenteront de préférence une forme en couronne de façon à laisser dégagé l'axe du conteneur. Celà dans le but de faciliter la transmission de l'allumage d'un conteneur à l'autre.In all cases, the attachment means will preferably have a crown shape so as to leave the axis of the container free. This in order to facilitate the transmission of ignition from one container to another.

La figure 3 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 totalements identiques.FIG. 3 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.

Il présente ainsi un rétreint à chacune de ses extrémités, les rétreints 5 et 6 sont de longueurs différentes et la bague 2 (représentée en coupe, les lames n'étant pas figurées) est disposée sur le rétreint 5 le plus long.It thus has a constriction at each of its ends, the constrictions 5 and 6 are of different lengths and the ring 2 (shown in section, the blades not being shown) is disposed on the longest constriction 5.

Les faces frontales 3a, 3b portent des éléments d'accrochage 4a, 4b autoagrippants. L'élément autoagrippant 4a étant du type complémentaire de l'élément 4b.The front faces 3a, 3b carry hooking elements 4a, 4b hook and loop. The hook-and-loop element 4a being of the type complementary to the element 4b.

Il est alors possible d'assembler plusieurs conteneurs 1 de façon à réaliser des charges d'une puissance donnée. Un tel conteneur est particulièrement adapté à l'artillerie de campagne.It is then possible to assemble several containers 1 so as to carry out loads of a given power. Such a container is particularly suitable for field artillery.

La figure 4 représente deux conteneurs selon l'invention constituant un chargement en deux fardeaux, par exemple pour véhicule blindé. Ce chargement comprend un conteneur de base 12 (représenté en demi coupe) qui porte un culot 14, par exemple métallique, un tube allumeur 15 et qui contient une charge propulsive 17.FIG. 4 represents two containers according to the invention constituting a load in two bundles, for example for an armored vehicle. This load comprises a base container 12 (shown in half section) which carries a base 14, for example metallic, an igniter tube 15 and which contains a propellant charge 17.

Il comprend également un conteneur porte-projectile 13 qui contient ici une charge propulsive (non représentée) et éventuellement une composition d'allumage de cette dernière et sur lequel est disposé un projectile 16 de type connu (explosif, flèche ou autre).It also includes a projectile container 13 which here contains a propellant charge (not shown) and optionally an ignition composition of the latter and on which is disposed a projectile 16 of known type (explosive, arrow or other).

En fonction des besoins balistiques, il serait possible également de définir un conteneur porte projectile ne comprennant pas de charge propulsive.Depending on ballistic needs, it would also be possible to define a projectile container that does not include a propellant charge.

Dans ce mode particulier de réalisation, le conteneur de base 12 porte la bague 2 sur un rétreint 5 ainsi qu'un élément d'accrochage autoagrippant 4a sur la face frontale 3a (les moyens de verrouillage axial de la bague sont du type décrit précédemment et ne sont pas représentés ici pour simplifier la figure).In this particular embodiment, the base container 12 carries the ring 2 on a constriction 5 as well as a hook-and-loop fastening element 4a on the front face 3a (the means of axial locking of the ring are of the type described above and are not shown here to simplify the figure).

Le conteneur porte projectile 13 présente un rétreint 6 (de préférence plus court que le rétreint 5 du conteneur de base) et il porte un élément d'accrochage autoagrippant 4b, de type complémentaire de l'élément 4a, sur sa face frontale 3b.The projectile container 13 has a constriction 6 (preferably shorter than the constriction 5 of the base container) and it carries a hook-and-loop fastening element 4b, of the type complementary to the element 4a, on its front face 3b.

Suivant un autre mode de réalisation (non représenté ici), il est possible de prévoir un conteneur porte projectile sur lequel est disposé la bague, le conteneur de base portant un rétreint court et un élément auto agrippant.According to another embodiment (not shown here), it is possible to provide a projectile container on which the ring is arranged, the basic container carrying a short neck and a self-gripping element.

Suivant d'autres modes de réalisation il est possible de remplacer les éléments autoagrippants par une ou plusieurs feuilles adhésives disposées sur l'un et/ou l'autre des deux conteneurs.According to other embodiments, it is possible to replace the hook-and-loop elements with one or more adhesive sheets placed on one and / or the other of the two containers.
