Description

DISPOSITIF DE CALAGE POUR OBUS ET CASIER A CHARGESSETTING DEVICE FOR OBUS AND LOADED RACK
PROPULSIVES APTE A ACCUEILLIR UN TEL DISPOSITIF PROPULSIVE FIT TO HOST ONE SUCH DEVICE
Le domaine technique de l'invention est celui des dispositifs de calage pour obus ainsi que des casiers à charges propulsives. The technical field of the invention is that of shelling devices for shells as well as lockers with propellant charges.
Afin de transporter des munitions d'artillerie, il est connu de transporter les charges propulsives dans des containers ou magasins comprenant des casiers, dit casiers à charges. Chaque casier peut recevoir un étui ou emballage de charges. Les obus sont disposés par ailleurs dans d'autres casiers d'un magasin à obus. Les dimensions des casiers recevant les obus sont inférieures à celles des casiers recevant les étuis pour charges propulsives.  In order to transport artillery ammunition, it is known to transport the propellant charges in containers or magazines comprising bins, known as charge bins. Each locker can receive a holster or packing of loads. The shells are also placed in other lockers of a shell magazine. The dimensions of the bins receiving the shells are smaller than those of the bins receiving the cases for propelling charges.
Le brevet DE19529914 décrit ainsi un magasin à obus et des moyens facilitant le retrait des obus du magasin. Ces moyens comportent un tiroir qui peut coulisser dans des rainures du magasin grâce à des galets. Les casiers d'un tel magasin ont des dimensions réduites, légèrement supérieures au diamètre de l'obus. Un tel casier ne peut porter des charges propulsives dont les dimensions, quel que soit le calibre, comportent toujours un diamètre bien supérieur au calibre de l'obus.  Patent DE19529914 thus describes a shell magazine and means facilitating the removal of shells from the magazine. These means comprise a drawer which can slide in grooves of the store by means of rollers. The bins of such a store have small dimensions, slightly larger than the diameter of the shell. Such a rack can not carry propelling charges whose dimensions, whatever the caliber, always have a diameter much larger than the caliber of the shell.
Le brevet DE2620930 divulgue par ailleurs un magasin comportant un étage supérieur composé de casiers à charges et un étage inférieur composé de casiers à obus. Comme dans le brevet DE19529914, chaque casier à obus est équipé d'un tiroir permettant l'extraction de l'obus  The patent DE2620930 also discloses a store comprising an upper stage consisting of charge bins and a lower stage consisting of shell bins. As in patent DE19529914, each shell case is equipped with a drawer for extracting the shell
Les besoins opérationnels peuvent nécessiter un emport accru d'obus et il serait alors intéressant de pouvoir mettre des obus en réserve dans les casiers destinés aux charges propulsives .  Operational requirements may require increased shells and it would be interesting to be able to put shells in the lockers for propellant charges.
Il se pose alors un problème d'adaptation des casiers à charges qui sont beaucoup trop spacieux pour recevoir des obus puisque chaque casier est adapté à contenir une ou plusieurs charges propulsives mises en place dans un étui ou emballage . It then poses a problem of adaptation of the load boxes which are much too spacious to receive shell since each rack is adapted to contain one or more propellant charges put in place in a case or packaging.
Les obus n'étant pas calés, ils sont alors mobiles et se heurtent aux parois des casiers à charges, pouvant causer des dégradations au casier mais aussi à l'obus et sa fusée.  The shells are not wedged, they are then mobile and collide with the walls of the lockers with loads, which can cause damage to the locker but also to the shell and its rocket.
L'invention propose de résoudre ce problème de calage en proposant des dispositifs de calage d'obus et des casiers à charges aptes à recevoir de tels dispositifs de calage selon l'invention.  The invention proposes to solve this problem of wedging by proposing shells setting devices and load lockers adapted to receive such rigging devices according to the invention.
Ainsi, l'invention porte sur un dispositif de calage à l'horizontale pour un obus destiné à être positionné dans un casier à charges propulsives, dispositif comportant un auget destiné à être placé dans le casier, auget comportant des surfaces de soutien destinées à soutenir l'obus et des surfaces d'appui comportant des montants destinés à être en contact avec des parois latérales du casier de manière à interdire tout mouvement transversal du dispositif relativement au casier, les surfaces de soutien étant par ailleurs disposées dans le casier de manière à positionner l'axe longitudinal de l'obus à une distance R d'une partie supérieure du casier sensiblement égale au rayon de l'obus de manière à interdire les mouvements transversaux ascendant de l'obus, dispositif comportant un moyen de blocage longitudinal de l'obus apte à pivoter entre une position de blocage où il prend appui sur l'ogive de l'obus et une position ouverte où il est à distance de l'obus, 1 'auget comportant un moyen d'arrêt destiné à coopérer avec une interface d'arrêt solidaire du casier.  Thus, the invention relates to a horizontal setting device for a shell intended to be positioned in a propulsive container, device comprising a bucket for placing in the bin, bucket having support surfaces for supporting the shell and bearing surfaces comprising uprights intended to be in contact with the side walls of the rack so as to prohibit any transverse movement of the device relative to the rack, the support surfaces being also arranged in the rack so as to positioning the longitudinal axis of the shell at a distance R from an upper part of the rack substantially equal to the radius of the shell so as to prohibit the upward transverse movements of the shell, a device comprising a longitudinal locking means of the shell; shell capable of pivoting between a blocking position where it is supported on the shell of the shell and an open position where it is remote from the shell , The bucket 1 having a stop means for cooperating with a stop interface secured to the rack.
Avantageusement, les surfaces de soutien forment un angle relativement l'une à l'autre et sont aptes à être tangentes chacune avec une génératrice distincte de l'obus. Avantageusement, les surfaces de soutien forment un profil semi cylindrique destiné à correspondre avec un profil de l'obus. Advantageously, the support surfaces form an angle relatively to one another and are able to be tangent each with a generator separate from the shell. Advantageously, the support surfaces form a semi-cylindrical profile intended to correspond with a profile of the shell.
Avantageusement, les surfaces d'appui comportent un revêtement antifriction de manière à permettre le glissement aisé de l'obus.  Advantageously, the bearing surfaces comprise an anti-friction coating so as to allow easy sliding of the shell.
Avantageusement, le moyen de blocage comporte un levier dont une première extrémité comporte une fourche prenant appui sur l'ogive en au moins deux points de celle-ci diamétralement opposés lorsque le moyen de blocage est en position de blocage.  Advantageously, the locking means comprises a lever whose first end comprises a fork bearing on the ogive at at least two points thereof diametrically opposed when the locking means is in the locking position.
Avantageusement, le dispositif comporte un verrou apte à verrouiller le levier en position de blocage.  Advantageously, the device comprises a lock adapted to lock the lever in the locking position.
Avantageusement, la seconde extrémité du levier est orientée vers le bas du dispositif et comporte un axe de pivotement transversal au dispositif.  Advantageously, the second end of the lever is oriented towards the bottom of the device and has a pivot axis transverse to the device.
Avantageusement, le centre de gravité du levier est décalé par rapport à un plan vertical passant par l'axe de pivotement du levier de manière à permettre de provoquer un pivotement du levier par gravité.  Advantageously, the center of gravity of the lever is offset relative to a vertical plane passing through the axis of pivoting of the lever so as to cause a pivoting of the lever by gravity.
Avantageusement, l'auget comporte un arrêtoir destiné à interférer avec l'arrière de l'obus.  Advantageously, the bucket has a stop for interfering with the rear of the shell.
L'invention porte également sur un container de charges propulsives comportant au moins un casier à charges propulsives destiné à recevoir un dispositif de calage d'obus, container caractérisé en ce que chaque casier comporte au moins une interface d'arrêt destinée à coopérer avec un moyen d'arrêt porté par l'auget de manière à empêcher la translation longitudinale du dispositif de calage relativement au casier.  The invention also relates to a container of propellant charges comprising at least one propellant charge rack for receiving a shell setting device, container characterized in that each rack comprises at least one stop interface intended to cooperate with a stop means carried by the trough so as to prevent the longitudinal translation of the wedging device relative to the rack.
Avantageusement, l'interface d'arrêt pourra comporter au moins un bossage cylindrique solidaire d'une paroi latérale du casier. L'invention sera mieux comprise à la lecture de la description suivante, description faite à la lumière des dessins en annexe, dessins dans lesquels : Advantageously, the stop interface may comprise at least one cylindrical boss integral with a side wall of the rack. The invention will be better understood on reading the following description, a description given in the light of the appended drawings, in which:
La figure 1 représente une vue de trois quarts d'un dispositif de calage selon l'invention.  Figure 1 shows a three-quarter view of a wedging device according to the invention.
La figure 2 représente une vue de détail en coupe longitudinale du dispositif selon l'invention en position de blocage .  FIG. 2 represents a detail view in longitudinal section of the device according to the invention in the locked position.
La figure 3 représente une vue de détail en coupe longitudinale du dispositif selon l'invention en position ouverte .  Figure 3 shows a detail view in longitudinal section of the device according to the invention in the open position.
La figure 4 représente une vue partielle d'un container selon l'invention équipé de casiers.  Figure 4 shows a partial view of a container according to the invention equipped with bins.
La figure 5 représente une autre vue partielle d'un container selon l'invention équipé de casiers et montrant un casier renfermant une charge et un casier renfermant un obus.  Figure 5 shows another partial view of a container according to the invention equipped with bins and showing a rack containing a load and a locker containing a shell.
Selon la figure 1, un dispositif de calage 1 selon l'invention comporte un auget 2 destiné à porter un obus 100. According to Figure 1, a wedging device 1 according to the invention comprises a bucket 2 for carrying a shell 100.
Cet auget 2 est réalisé par exemple en tôle pliée, et il comporte un profil en forme de M (le profil en M est mieux vu à la figure 4), profil qui s'étend sensiblement sur toute la longueur de l'obus 100.  This bucket 2 is made for example of folded sheet, and has a profile in the form of M (the profile in M is best seen in Figure 4), which profile extends substantially over the entire length of the shell 100.
Des surfaces de soutien 3 reçoivent l'obus 100 pour le soutenir et le caler latéralement en formant un V sous l'obus 100. Ces surfaces de soutien 3 forment ainsi un angle relativement l'une à l'autre et sont aptes à être tangentes chacune avec une génératrice distincte de l'obus 100  Supporting surfaces 3 receive the shell 100 to support it and wedge laterally forming a V under the shell 100. These support surfaces 3 thus form an angle relatively to one another and are able to be tangent each with a generator separate from the shell 100
(tangentes T visibles à la figure 4) . Les surfaces de soutien 3 sont recouvertes d'un revêtement anti friction qui pourra comporter par exemple des plaques de polytétrafluoroéthylène haute densité afin de permettre une manipulation (introduction/extraction) longitudinale de l'obus 100 aisée par l'utilisateur. Le dispositif de calage 1 comporte des surfaces d'appui 4 comportant des montants verticaux 4 s 'étendant sur toute la longueur de l'auget 2. Les surfaces d'appui 4 sont destinées à interférer par leurs parties planes latérales (branches du M) et verticales et par leur tranche inférieure avec les parois d'un casier comme nous allons le voir plus loin à la figure 4. (Tangents T visible in Figure 4). The support surfaces 3 are covered with an anti-friction coating which may comprise, for example, high density polytetrafluoroethylene plates in order to allow longitudinal manipulation (insertion / extraction) of the shell 100 by the user. The wedging device 1 comprises bearing surfaces 4 comprising vertical uprights 4 extending over the entire length of the bucket 2. The bearing surfaces 4 are intended to interfere with their lateral plane portions (branches of the M). and vertical and their lower edge with the walls of a locker as we will see later in Figure 4.
La partie avant AV du dispositif 1 comporte un moyen de blocage 5, destiné à empêcher la translation de l'obus 100 vers l'avant AV du dispositif 1. Le moyen de blocage 5 visible à la figure 1 comporte un levier 6.  The front part AV of the device 1 comprises a blocking means 5, intended to prevent the translation of the shell 100 towards the front AV of the device 1. The blocking means 5 visible in FIG. 1 comprises a lever 6.
Le levier 6 comporte à sa première extrémité une fourche 7 apte à correspondre avec l'ogive de l'obus 100 fournissant une zone d'appui semi circulaire offrant au moins deux points d'appui diamétralement opposés par rapport à l'axe longitudinal 101 de l'obus 100.  The lever 6 comprises at its first end a fork 7 adapted to correspond with the ogive of the shell 100 providing a semi-circular bearing zone providing at least two diametrically opposite bearing points relative to the longitudinal axis 101 of the shell 100.
Le moyen de blocage 5 pourra être situé à une distance D réduite de l'ogive (figure 2), l'essentiel étant qu'il puisse arrêter l'obus 100 lors d'une éventuelle translation longitudinale de celui-ci sans prendre appui sur la fusée 200 de l'obus 100.  The locking means 5 may be situated at a reduced distance D from the nose (FIG. 2), the essential point being that it can stop the shell 100 during a possible longitudinal translation thereof without relying on the rocket 200 of the shell 100.
La seconde extrémité du levier 6 comporte une liaison pivot 8 permettant au moyen de blocage 5 de pivoter entre une position de blocage et une position ouverte. La position ouverte, représentée à la figure 3, permet de dégager le moyen de blocage 5 de la trajectoire longitudinale de l'obus 100 glissant sur les surfaces de soutien 3.  The second end of the lever 6 comprises a pivot connection 8 allowing the locking means 5 to pivot between a locking position and an open position. The open position, represented in FIG. 3, makes it possible to disengage the locking means 5 from the longitudinal trajectory of the shell 100 sliding on the support surfaces 3.
Un bouton de blocage 9 formant butée permet de verrouiller le moyen de blocage 5 en position de blocage.  A locking button 9 forming a stop locks the locking means 5 in the locking position.
On notera à la figure 2 que le levier 6 comporte une masselotte 10 qui décale le centre de gravité du levier d'un plan vertical passant par l'axe de la liaison pivot 8, produisant ainsi un couple de pivotement. Ainsi, selon la figure 3, lorsque le bouton de blocage 9 est actionné, ce couple engendre le pivotement du levier 6 vers le bas ce qui dégage le moyen de blocage 5 de la trajectoire longitudinale d'extraction de l'obus 100 vers l'avant AV. It will be noted in Figure 2 that the lever 6 comprises a feeder 10 which shifts the center of gravity of the lever of a vertical plane passing through the axis of the pivot connection 8, thereby producing a pivoting torque. Thus, according to FIG. 3, when the locking button 9 is actuated, this torque generates the pivoting of the lever 6 downwards which releases the blocking means 5 from the longitudinal trajectory of the extraction of the shell 100 towards the before AV.
Selon un mode de réalisation évident pour l'Homme du Métier mais non représenté, le levier 5 pourrait ne pas comporter de masselotte 10. Il sera alors nécessaire de faire basculer manuellement le levier 6 pour extraire l'obus.  According to an embodiment which is obvious to a person skilled in the art but not shown, the lever 5 may not include a flyweight 10. It will then be necessary to manually tilt the lever 6 to extract the shell.
Afin de bloquer la translation longitudinale de l'obus In order to block the longitudinal translation of the shell
100 vers l'arrière AR du dispositif 1, l'auget 2 pourra comporter un arrêtoir 12 destiné à interférer avec la face arrière de l'obus 100 (figure 1) . 100 to the rear AR of the device 1, the bucket 2 may include a retainer 12 for interfering with the rear face of the shell 100 (Figure 1).
Selon la figure 4, un container 15 ou magasin 15 de charges comporte des casiers 11 à charges propulsives contigus .  According to FIG. 4, a container 15 or load store 15 comprises bins 11 with contiguous propellant charges.
On a représenté un casier 11 contenant un dispositif de calage 1 selon l'invention.  There is shown a rack 11 containing a wedging device 1 according to the invention.
Pour des facilités de représentation, seul un casier à charge 11 est représenté équipé d'un tel dispositif de calage 1, mais il est évident pour l'Homme du Métier que chaque casier à charge 11 peut contenir un dispositif 1 selon 1 ' invention .  For ease of representation, only a load bin 11 is shown equipped with such a wedging device 1, but it is obvious to those skilled in the art that each load bin 11 may contain a device 1 according to the invention.
On note à cette figure 4 que les montants verticaux 4 forment des surfaces d'appui 4 qui interfèrent latéralement avec les parois latérales 16 du casier à charge 11. La tranche de chacun de ces montants 4 est en appui sur la paroi inférieure du casier 11. De cette manière, les montants verticaux 4 empêchent toutes translations transversales ou horizontales de l'auget 2 (flèche H) et tout mouvement de l'auget 2 vers le bas relativement au casier 11 (flèche V) .  It is noted in this FIG. 4 that the vertical uprights 4 form bearing surfaces 4 which interfere laterally with the side walls 16 of the load rack 11. The edge of each of these uprights 4 bears against the bottom wall of the rack 11 In this way, the uprights 4 prevent any transverse or horizontal translations of the bucket 2 (arrow H) and any movement of the bucket 2 downwards relative to the rack 11 (arrow V).
L'Homme du Métier dimensionnera les surfaces d'appui 4 et les surfaces de soutien 3 de manière à positionner l'axe longitudinal de l'obus 100 à une distance R de la paroi supérieure du casier 11, distance R qui est sensiblement égale au rayon maximal R de l'obus 100, de manière à interdire les mouvements verticaux ascendant de l'obus 100. Those skilled in the art will dimension the bearing surfaces 4 and the support surfaces 3 so as to position the longitudinal axis of the shell 100 at a distance R from the wall upper bin 11, distance R which is substantially equal to the maximum radius R of the shell 100, so as to prohibit the upward vertical movements of the shell 100.
De cette manière le dispositif de calage 1 permet de compenser l'espace excessif offert par le casier 11 seul et il bloque radialement l'obus 100.  In this way the wedging device 1 makes it possible to compensate for the excessive space offered by the rack 11 alone and it blocks the shell 100 radially.
A la figure 5 un casier à charge 11 de la partie supérieure du container 15 est occupé par une charge propulsive 20 contenue dans son emballage 21. Ce type d'emballage 21 de section octogonale cale verticalement et horizontalement la charge 20 en prenant appui par ses faces supérieure, inférieure et latérales, sur les parois du casier 11. Il est ainsi visible clairement qu'un obus 100 présente un diamètre D nettement inférieur à la largeur L et à la hauteur d'un emballage 21 de charge 20 et nécessite donc un calage adapté qui est réalisé par un dispositif de calage selon l'invention.  In FIG. 5, a load bin 11 of the upper part of the container 15 is occupied by a propellant charge contained in its packaging 21. This type of packaging 21 of octagonal cross-section holds vertically and horizontally the load 20 while being supported by its upper, lower and lateral faces, on the walls of the rack 11. It is thus clearly visible that a shell 100 has a diameter D significantly less than the width L and the height of a load package 20 and therefore requires a adapted wedging which is achieved by a wedging device according to the invention.
Dans le cas où l'auget 2 ne comporte pas d'arrêtoir 12 comme à la figure 1, l'Homme du Métier positionnera le moyen de blocage 5 longitudinalement de manière à ce que la face arrière de l'obus 100 soit en appui sur le fond du casier 11. C'est alors le fond du casier qui limitera la translation longitudinale vers l'arrière de l'obus dans le casier.  In the case where the bucket 2 has no stop 12 as in Figure 1, the skilled person will position the locking means 5 longitudinally so that the rear face of the shell 100 is supported on the bottom of the rack 11. It is then the bottom of the rack which will limit the longitudinal translation towards the rear of the shell in the locker.
Afin d'empêcher d'éventuels mouvements de translation longitudinaux du dispositif 1 par rapport au casier 11, le dispositif 1 comporte un moyen d'arrêt 13 (ici une encoche), visible à la figure 2 qui est destiné à correspondre avec une interface d'arrêt 14 du casier 11 visible à la figure 4 (ici un bossage 14).  In order to prevent any longitudinal translation movements of the device 1 relative to the rack 11, the device 1 comprises a stop means 13 (here a notch), visible in FIG. 2, which is intended to correspond with an interface of FIG. stop 14 of the rack 11 visible in Figure 4 (here a boss 14).
En l'espèce, chaque montant 4 comporte donc au niveau de sa tranche inférieure une encoche 13 apte à correspondre avec un bossage 14 cylindrique solidaire de chaque paroi latérale 16 du casier 11 par vissage, ce qui a pour effet de bloquer la translation du dispositif 1. En introduisant un dispositif 1 selon l'invention dans un casier 11 à charge on constate qu'il est facile de caler un obus 100 dans un tel casier à charge, ce qui permet d'augmenter la capacité d'emport en obus d'un véhicule comportant des casiers à charge. In this case, each upright 4 therefore comprises at its lower edge a notch 13 adapted to correspond with a cylindrical boss 14 secured to each side wall 16 of the rack 11 by screwing, which has the effect of blocking the translation of the device. 1. By introducing a device 1 according to the invention in a rack 11 to load it is found that it is easy to wedge a shell 100 in such a load bin, which allows to increase the carrying capacity in shells of a vehicle with cargo lockers.
Selon un mode de réalisation non représenté, l'auget 2 pourra avoir une forme semi cylindrique qui recevra l'obus au niveau de sa partie de plus grand diamètre.  According to an embodiment not shown, the bucket 2 may have a semi-cylindrical shape that will receive the shell at its larger diameter portion.
