  • the carriage is formed of a frame 11 secured to a base plate 12.
  • the frame 11 is constituted by a mechanically welded assembly of bars 33 which form the fork of the carriage 2, assembly which supports the two sockets 5 intended to receive the pins of the cradle.
  • the side bars 33 are assembled laterally on either side of a space intended to receive the cradle of the weapon. These bars thus form two parallel vertical panels 13a and 13b, constituting the fork, and each sleeve 5 extends perpendicular to each panel 13a, 13b towards the outside of the frame 11.
  • the sleeves 5 are supported towards the outside of the frame 11 by other side bars 33 which form support triangles 14a, 14b which extend, parallel to the panels 13a and 13b, from the socket 5 towards the base plate 12.
  • the panels 13a and 13b are also connected by spacers 15 which make it possible to stiffen the frame.
  • This basic structure of hide 2 makes it possible to design a hide that is both light and resistant.
  • the sleeves 5 participate in the stiffening of the assembly and extend on either side of the fork. Between each socket 5 and the base plate 12 extends a space intended to receive the box of a store.
  • armor plates 15a and 15b are fixed to the frame 11 between the panels 13a and 13b of the fork.
  • the figure 2c shows the placement of boxes 8a and 8b between each trunnion 5 and base plate 12.
  • each box is also made in the form of a mechanically welded structure which is fixed by screwing to base plate 12.
  • Each box thus contributes, with a reduced mass, to stiffen the carriage 2 by laterally reinforcing each panel 13a or 13b.
  • the side walls of each box are connected by spacers 16 which contribute to the rigidity of the box and which also make it possible to separate and maintain the ammunition boxes which will be placed in the box (see also figure 1c ).
  • FIG. 2c We represented at the figure 2c an upper cover 17 which is fixed to the box 8a at a lateral articulation 18 and which allows access to the upper part of at least one box once it is placed in the box 8a.
  • the cover 17 gives access to the three boxes which are arranged at the front of the box 8a.
  • the box on the right 8a contains a total of five ammunition boxes, three boxes are introduced into the box 8a by the upper opening of the box 8a, after release of the cover 17, the two other boxes are introduced into the box 8a by the opening rear 9a, as will be described later.
  • the other box 8b does not carry a lid. Indeed this box is smaller in size and contains only two boxes 10 which are introduced into the box 8b through the rear opening 9b. The front part of this left box 8b will be able to receive the electronic control units of the weapon or of the turret. They will be accessible through a side door 30 ( figure 1b ).
  • the 2d figure shows the lookout 2 after fixing armor plates 31 on the side walls of the boxes 8a and 8b.

On the figure 1c , the plates 31 are not fixed to the frame 11.
  • the carriage 2 of the turret comprises two boxes 8a and 8b which are integral with the frame 11, and which are arranged symmetrically on either side of a median plane P ( 2d figure ) perpendicular to the axis 32 of the sockets 5 receiving the pins (therefore also with respect to the axis 32 of the pins).
  • caissons 8a, 8b have an ammunition capacity which is significant, they are shielded and ensure the protection of the ammunition. They also ensure the protection of an operator who would implement the weapon manually or who would reload the magazines from the rear as will be described later.
  • the frame 11 of the turret according to the invention also makes it possible to define a turret whose length of the boxes 8a, 8b is different, and this without changing the frame. Indeed, as we see in figures 2a to 2d , the boxes 8a and 8b can have different lengths to receive more or less boxes 10.
  • the frame 11 therefore makes it possible to give a certain modularity to the architecture of the turret.
  • the figures 4a and 4b show in perspective a box 10 intended to be positioned in one of the boxes 8a or 8b.
  • This body 10 is substantially parallelepipedic and it comprises two front walls 19a and 19b which are parallel to each other.
  • the box 10 also comprises two side walls 20a and 20b which are parallel to each other and which are also perpendicular to the front walls 19a and 19b.
  • the front walls 19a and 19b both have a height which is lower than that of the side walls 20a and 20b. Such an arrangement allows strip 21 of ammunition 22 to exit box 10 above front walls 19a and 19b, while strip 21 is still held transversely by side walls 20a and 20b.
  • the 4d figure thus schematically shows five boxes 10 1 , 10 2 , 10 3 , 10 4 and 10 5 positioned next to each other in a box 8a, and whose strips 21 are connected to each other, allowing the smooth feeding of tear. Closing the lid 17 of the box 8a does not interfere with the progression of the band 21 from one box to another and up to the weapon. Thanks to the access to the internal volume of the box which is given by the lid 17, it is possible thanks to the invention to connect the strip 21 from one box to another by skipping one or more boxes.
  • the body 10 comprises a roller 25 which is positioned at a front wall 19a or 19b.
  • This roller 25 is carried by a pivoting handle 42 comprising two arms 26 which are articulated on the side walls 20a and 20b.
  • Cove 42 formed by the roller 25 and the arms 26 thus form a handle allowing the extraction of the box 10 from the box 8a as well as the transport of the box 10.
  • the handle is folded down, as shown in figure 4a , the axis 27 of the roller bears against a notch 24 of each side wall 20a, 20b and the roller 25 can freely rotate on its axis 27.

  • This plate 29 is more particularly visible to figure 1c and 7 .
  • the configuration of the turret according to the invention makes it possible to receive a relatively large number of ammunition boxes under a light and compact architecture.
  • the box on the right 8a can receive five boxes 10. Three boxes are introduced into the box 8a through its upper opening, after tilting the lid 17. The operator can easily connect the strips to each other to lead the strip 21 of ammunition to a feed star (not shown) of the weapon, star which is located in the vicinity of the socket 5 and which guides the strip to the corridors 7a and 7b (visible at figure 1b ).
  • the boxes 10 1 , 10 2 and 10 3 are held relative to the casing 8a by a locking means which comprises, on the one hand the spacers 16 which pass through the casing 8a and connect its two side walls, and on the other hand the upper cover 17 closing the box 8a.

Description

Le domaine technique de l'invention est celui des tourelles canon et plus particulièrement des dispositifs d'alimentation en munitions qui sont solidaires de telles tourelles.The technical field of the invention is that of gun turrets and more particularly ammunition feed devices which are integral with such turrets.

D'une façon classique une tourelle canon comprend un affût portant un berceau qui reçoit une arme.Conventionally, a gun turret comprises a carriage carrying a cradle which receives a weapon.

Le berceau est pivotant par rapport à l'affût pour permettre un pointage en site. A cet effet, le berceau comporte des tourillons qui sont montés pivotants dans des douilles solidaires de l'affût.The cradle is pivotable in relation to the carriage to allow pointing in elevation. To this end, the cradle comprises trunnions which are pivotally mounted in sockets integral with the carriage.

L'affût lui-même sera le plus souvent monté pivotant par rapport à une embase solidaire d'un véhicule ou d'une structure. Une telle disposition permet le pointage en gisement de l'arme.The carriage itself will most often be pivotally mounted with respect to a fixed base of a vehicle or of a structure. Such an arrangement allows the aiming in bearing of the weapon.

Le dispositif d'alimentation en munitions comporte, d'une part au moins un magasin à munitions et, d'autre part, au moins un couloir d'alimentation conduisant les munitions du magasin vers l'arme.The ammunition feed device comprises, on the one hand at least one ammunition store and, on the other hand, at least one feed passage leading the ammunition from the store to the weapon.

Le brevet US5299487 décrit une telle tourelle qui a la particularité d'être quadri-tubes et qui comporte donc quatre magasins à munitions, chaque magasin étant dédié à un tube d'arme.The patent US5299487 describes such a turret which has the particularity of being four-tube and which therefore comprises four ammunition magazines, each magazine being dedicated to a weapon tube.

Cette tourelle a une structure compacte, les magasins sont disposés latéralement au berceau et se trouvent sensiblement en dessous des douilles qui reçoivent les tourillons.This turret has a compact structure, the stores are arranged laterally to the cradle and are located substantially below the sockets which receive the pins.

Cette tourelle connue présente cependant l'inconvénient de ne pas permettre un réapprovisionnement simple des magasins en munitions. En particulier les magasins situés le plus en avant de la tourelle ne peuvent être alimentés sous protection des servants.This known turret, however, has the disadvantage of not allowing a simple replenishment of ammunition magazines. In particular, the stores located furthest forward of the turret cannot be supplied under the protection of the servants.

C'est le but de l'invention que de proposer une tourelle dont l'architecture permet de faciliter le réapprovisionnement en munitions d'une façon rapide et protégée.It is the object of the invention to propose a turret whose architecture makes it possible to facilitate the replenishment of ammunition in a rapid and protected manner.

Le brevet US3788189 décrit une tourelle canon conforme au préambule de la revendication 1.The patent US3788189 describes a gun turret according to the preamble of claim 1.

Selon un mode de réalisation, le caisson pourra comporter un couvercle supérieur pouvant être ouvert et permettant de donner accès à la partie supérieure d'au moins une caisse et permettant d'introduire ou de retirer ladite caisse.According to one embodiment, the box may include an upper cover which can be opened and which gives access to the upper part of at least one box and which allows said box to be introduced or removed.

Selon un mode de réalisation, le caisson pourra comporter une porte disposée au niveau de sa partie arrière, porte venant obturer l'ouverture disposée au niveau de l'extrémité arrière du caisson et permettant l'introduction d'au moins une caisse dans le caisson.According to one embodiment, the box may include a door arranged at its rear part, door coming to close the opening arranged at the level of the rear end of the box and allowing the introduction of at least one box in the box .

Le moyen de verrouillage d'au moins une caisse par rapport au caisson pourra comprendre, d'une part des entretoises traversant le caisson et reliant deux parois latérales du caisson et d'autre part le couvercle supérieur fermant le caisson.The means for locking at least one box with respect to the box may comprise, on the one hand, spacers passing through the box and connecting two side walls of the box and, on the other hand, the upper cover closing the box.

Le moyen de verrouillage d'au moins une caisse par rapport au caisson pourra comprendre la porte arrière.The locking means of at least one box relative to the box may include the rear door.

Selon un mode de réalisation, la tourelle pourra comporter au moins un plateau disposé derrière le caisson et permettant de recevoir une caisse avant son introduction dans le caisson.According to one embodiment, the turret may comprise at least one plate arranged behind the box and allowing to receive a box before its introduction into the box.

La caisse pourra avantageusement être rendue solidaire du plateau.The fund can advantageously be made integral with the tray.

Selon d'autres caractéristiques, le caisson pourra être solidaire d'une ossature solidaire d'une plaque de base, ossature comportant des barres latérales disposées de part et d'autre du caisson et portant aussi une douille destinée à recevoir un tourillon.According to other characteristics, the casing may be secured to a framework secured to a base plate, this framework comprising side bars arranged on either side of the casing and also carrying a socket intended to receive a pin.

La tourelle canon pourra comporter deux caissons solidaires de l'ossature, et disposés de façon symétrique de part et d'autre d'un plan médian perpendiculaire à l'axe des douilles.The gun turret may comprise two caissons integral with the framework, and arranged symmetrically on either side of a median plane perpendicular to the axis of the casings.

Est également divulguée par la présente, mais ne faisant pas partie de l'invention revendiquée, une caisse à munitions destinée à équiper une telle tourelle canon, caisse sensiblement parallélépipédique et comprenant deux parois frontales parallèles entre elles et deux parois latérales parallèles entre elles et perpendiculaires aux parois frontales, les parois frontales ayant toutes deux une hauteur inférieure à celle des parois latérales pour permettre la sortie de munitions en bandes.Also disclosed herein, but not forming part of the claimed invention, is an ammunition box intended to equip such a gun turret, a substantially parallelepiped box and comprising two front walls parallel to each other and two side walls parallel to each other and perpendicular to the front walls, the front walls both having a height less than that of the side walls to allow the exit of ammunition in strips.

La caisse pourra comporter au moins un rouleau positionné au niveau d'une paroi frontale.The box may include at least one roller positioned at a front wall.

Le rouleau pourra être porté par une anse pivotante articulée sur les parois latérales et formant une poignée d'extraction et de transport de la caisse.The roller can be carried by a pivoting handle articulated on the side walls and forming a handle for extracting and transporting the box.

La caisse pourra comporter un renfoncement au niveau de la partie inférieure d'une paroi frontale, renfoncement délimité à l'avant par un bec solidaire de la face inférieure.The box may include a recess at the level of the lower part of a front wall, a recess delimited at the front by a spout integral with the lower face.

En se reportant aux figures la à 1c, une tourelle canon 1 selon l'invention comprend un affût 2 portant un berceau 3 recevant une arme 4.Referring to figures la to 1c, a gun turret 1 according to the invention comprises a mounting 2 carrying a cradle 3 receiving a weapon 4.

Le berceau 3 comporte des tourillons (non représentés) qui sont montés pivotant dans des douilles 5 de l'affût 2.The cradle 3 has pins (not shown) which are pivotally mounted in sockets 5 of the carriage 2.

Cette tourelle 1 comporte un dispositif d'alimentation en munitions qui comporte ici deux magasins à munitions, un magasin de droite 6a et un magasin de gauche 6b.This turret 1 comprises an ammunition feed device which here comprises two ammunition magazines, a right magazine 6a and a left magazine 6b.

Les magasins 6a et 6b sont disposés latéralement au berceau et chacun en dessous d'une des douilles 5 recevant un tourillon.Magazines 6a and 6b are arranged laterally to the cradle and each below one of sockets 5 receiving a journal.

Le dispositif d'alimentation en munitions comporte aussi deux couloirs d'alimentation 7a et 7b, qui conduisent chacun les munitions d'un des magasins vers l'arme 4.The ammunition feed device also comprises two feed corridors 7a and 7b, which each lead the ammunition from one of the magazines to the weapon 4.

Un couloir de droite 7a conduit les munitions provenant du magasin de droite 6a. Un couloir de gauche 7b conduit les munitions provenant du magasin de gauche 6b. Un capotage arrière 38 couvre les couloirs 7a et 7b. Ce capotage n'est représenté que sur la figure la.A right corridor 7a leads the ammunition from the right magazine 6a. A left corridor 7b leads the ammunition from the left magazine 6b. A rear cowling 38 covers the corridors 7a and 7b. This cowling is shown only in FIG.

L'arme 4 est ici une arme dite de moyen calibre (calibre inférieur à 60mm et supérieur à 12,7 mm). Cette arme est définie de façon à pouvoir tirer deux types de munitions différents, par exemple des munitions explosives et des munitions perforantes. La mécanique de l'arme comporte un moyen d'introduction de munitions permettant d'alimenter l'arme, au choix, avec l'un ou l'autre type de munitions. Une telle arme est connue par exemple par le brevet EP129457 .Weapon 4 is here a so-called medium-caliber weapon (caliber less than 60mm and greater than 12.7 mm). This weapon is defined so that it can fire two different types of ammo, for example explosive ammo and armour-piercing ammo. The mechanics of the weapon comprises a means of introducing ammunition making it possible to supply the weapon, as desired, with one or the other type of ammunition. Such a weapon is known for example from the patent EP129457 .

Elle ne fait pas l'objet de l'invention et il n'est donc pas nécessaire de la décrire en détails. L'invention pourrait tout à fait être réalisée avec une arme comportant deux tubes, chaque tube étant alimenté en munitions à partir d'un magasin distinct.It is not the subject of the invention and it is therefore not necessary to describe it in detail. The invention could very well be carried out with a weapon comprising two tubes, each tube being supplied with ammunition from a separate magazine.

Chaque magasin 6a ou 6b comporte un caisson externe 8a ou 8b qui est solidaire de l'affût 2 et à l'intérieur duquel peut être mis en place au moins une caisse 10 à munitions (voir figure 1b).Each magazine 6a or 6b comprises an outer box 8a or 8b which is integral with the carriage 2 and inside which can be placed at least one ammunition box 10 (see figure 1b ).

Chaque caisson 8a,8b comporte une extrémité arrière qui porte une ouverture (respectivement 9a et 9b) et une extrémité avant fermée (respectivement 23a et 23b).Each box 8a, 8b has a rear end which carries an opening (respectively 9a and 9b) and a closed front end (respectively 23a and 23b).

Des moyens de verrouillage sont prévus qui permettent d'immobiliser chaque caisse 10 par rapport à son caisson 8a ou 8b. Ces moyens de verrouillage seront décrits par la suite.Locking means are provided which make it possible to immobilize each box 10 with respect to its box 8a or 8b. These locking means will be described later.

Les figures 2a à 2d permettent de mieux comprendre l'architecture de la tourelle selon l'invention, la figure 2a montrant une première étape de réalisation de l'affût 2 et les figures 2b et 2c des étapes successives permettant de réaliser l'affût 2 complet tel que montré à la figure 2d.The figures 2a to 2d allow a better understanding of the architecture of the turret according to the invention, the figure 2a showing a first stage of realization of the carriage 2 and the figure 2b and 2c successive steps making it possible to produce the complete carriage 2 as shown in 2d figure .

Sur la figure 2a l'affût est formé d'une ossature 11 solidaire d'un plaque de base 12. L'ossature 11 est constituée par un assemblage mécanosoudé de barres 33 qui forment la fourche de l'affût 2, assemblage qui supporte les deux douilles 5 destinées à recevoir les tourillons du berceau.On the figure 2a the carriage is formed of a frame 11 secured to a base plate 12. The frame 11 is constituted by a mechanically welded assembly of bars 33 which form the fork of the carriage 2, assembly which supports the two sockets 5 intended to receive the pins of the cradle.

On voit sur la figure 2a que les barres latérales 33 sont assemblées latéralement de part et d'autre d'un espace destiné à recevoir le berceau de l'arme. Ces barres forment ainsi deux panneaux verticaux 13a et 13b parallèles, constituant la fourche, et chaque douille 5 s'étend perpendiculairement à chaque panneau 13a,13b vers l'extérieur de l'ossature 11. Les douilles 5 sont supportées vers l'extérieur de l'ossature 11 par d'autres barres latérales 33 qui forment des triangles support 14a, 14b qui s'étendent, parallèlement aux panneaux 13a et 13b, de la douille 5 vers la plaque de base 12.We see on the figure 2a that the side bars 33 are assembled laterally on either side of a space intended to receive the cradle of the weapon. These bars thus form two parallel vertical panels 13a and 13b, constituting the fork, and each sleeve 5 extends perpendicular to each panel 13a, 13b towards the outside of the frame 11. The sleeves 5 are supported towards the outside of the frame 11 by other side bars 33 which form support triangles 14a, 14b which extend, parallel to the panels 13a and 13b, from the socket 5 towards the base plate 12.

Les panneaux 13a et 13b sont par ailleurs reliés par des entretoises 15 qui permettent de rigidifier l'ossature.The panels 13a and 13b are also connected by spacers 15 which make it possible to stiffen the frame.

Cette structure de base de l'affût 2 permet de concevoir un affût à la fois léger et résistant. Les douilles 5 participent à la rigidification de l'ensemble et s'étendent de part et d'autre de la fourche. Entre chaque douille 5 et la plaque de base 12 s'étend un espace destiné à recevoir le caisson d'un magasin.This basic structure of hide 2 makes it possible to design a hide that is both light and resistant. The sleeves 5 participate in the stiffening of the assembly and extend on either side of the fork. Between each socket 5 and the base plate 12 extends a space intended to receive the box of a store.

Comme on le voit à la figure 2b, des plaques de blindage 15a et 15b sont fixées à l'ossature 11 entre les panneaux 13a et 13b de la fourche.As we see at the figure 2b , armor plates 15a and 15b are fixed to the frame 11 between the panels 13a and 13b of the fork.

La figure 2c montre la mise en place des caissons 8a et 8b entre chaque tourillon 5 et la plaque de base 12. On remarque que chaque caisson est également réalisé sous la forme d'une structure mécanosoudée qui est fixée par vissage à la plaque de base 12. Chaque caisson contribue ainsi, avec une masse réduite, à rigidifier l'affût 2 en renforçant latéralement chaque panneau 13a ou 13b. Les parois latérales de chaque caisson sont reliées par des entretoises 16 qui contribuent à la rigidité du caisson et qui permettent également de séparer et maintenir les caisses à munitions qui seront disposées dans le caisson (voir aussi figure 1c).The figure 2c shows the placement of boxes 8a and 8b between each trunnion 5 and base plate 12. Note that each box is also made in the form of a mechanically welded structure which is fixed by screwing to base plate 12. Each box thus contributes, with a reduced mass, to stiffen the carriage 2 by laterally reinforcing each panel 13a or 13b. The side walls of each box are connected by spacers 16 which contribute to the rigidity of the box and which also make it possible to separate and maintain the ammunition boxes which will be placed in the box (see also figure 1c ).

On a représenté à la figure 2c un couvercle supérieur 17 qui est fixé au caisson 8a au niveau d'une articulation latérale 18 et qui permet de donner accès à la partie supérieure d'au moins une caisse une fois qu'elle est mise en place dans le caisson 8a. Ici le couvercle 17 donne accès aux trois caisses qui sont disposées à l'avant du caisson 8a. Le caisson de droite 8a contient en tout cinq caisses à munitions, trois caisses sont introduites dans le caisson 8a par l'ouverture supérieure du caisson 8a, après dégagement du couvercle 17, les deux autres caisses sont introduites dans le caisson 8a par l'ouverture arrière 9a, comme cela sera décrit par la suite.We represented at the figure 2c an upper cover 17 which is fixed to the box 8a at a lateral articulation 18 and which allows access to the upper part of at least one box once it is placed in the box 8a. Here the cover 17 gives access to the three boxes which are arranged at the front of the box 8a. The box on the right 8a contains a total of five ammunition boxes, three boxes are introduced into the box 8a by the upper opening of the box 8a, after release of the cover 17, the two other boxes are introduced into the box 8a by the opening rear 9a, as will be described later.

L'autre caisson 8b ne porte pas de couvercle. En effet ce caisson est de taille plus réduite et ne renferme que deux caisses 10 qui sont introduites dans le caisson 8b par l'ouverture arrière 9b. La partie avant de ce caisson de gauche 8b pourra recevoir les boîtiers électroniques de commande de l'arme ou de la tourelle. Ils seront accessibles au travers d'une porte latérale 30 (figure 1b).The other box 8b does not carry a lid. Indeed this box is smaller in size and contains only two boxes 10 which are introduced into the box 8b through the rear opening 9b. The front part of this left box 8b will be able to receive the electronic control units of the weapon or of the turret. They will be accessible through a side door 30 ( figure 1b ).

La figure 2d montre l'affût 2 après fixation de plaques de blindage 31 sur les parois latérales des caissons 8a et 8b. Ces plaques 31 complètent la structure des caissons 8a,8b et assurent la protection des magasins à munitions contre les impacts balistiques. Sur la figure 1c, les plaques 31 ne sont pas fixées à l'ossature 11.The 2d figure shows the lookout 2 after fixing armor plates 31 on the side walls of the boxes 8a and 8b. These plates 31 complete the structure of the boxes 8a, 8b and ensure the protection of the ammunition magazines against ballistic impacts. On the figure 1c , the plates 31 are not fixed to the frame 11.

Ainsi, à l'issue du montage, l'affût 2 de la tourelle comporte deux caissons 8a et 8b qui sont solidaires de l'ossature 11, et qui sont disposés de façon symétrique de part et d'autre d'un plan médian P (figure 2d) perpendiculaire à l'axe 32 des douilles 5 recevant les tourillons (donc aussi par rapport à l'axe 32 des tourillons).Thus, at the end of the assembly, the carriage 2 of the turret comprises two boxes 8a and 8b which are integral with the frame 11, and which are arranged symmetrically on either side of a median plane P ( 2d figure ) perpendicular to the axis 32 of the sockets 5 receiving the pins (therefore also with respect to the axis 32 of the pins).

Ces caissons 8a,8b ont une capacité en munitions qui est importante, ils sont blindés et assurent la protection des munitions. Ils assurent aussi la protection d'un opérateur qui mettrait en œuvre l'arme manuellement ou qui procèderait au rechargement des magasins par l'arrière comme cela sera décrit par la suite.These caissons 8a, 8b have an ammunition capacity which is significant, they are shielded and ensure the protection of the ammunition. They also ensure the protection of an operator who would implement the weapon manually or who would reload the magazines from the rear as will be described later.

L'ossature 11 de la tourelle selon l'invention permet par ailleurs de définir une tourelle dont la longueur des caissons 8a,8b est différente, et ce sans pour autant changer l'ossature. En effet, comme on le voit aux figures 2a à 2d, les caissons 8a et 8b peuvent avoir des longueurs différentes pour recevoir plus ou moins de caisses 10. L'ossature 11 permet donc de donner une certaine modularité à l'architecture de la tourelle.The frame 11 of the turret according to the invention also makes it possible to define a turret whose length of the boxes 8a, 8b is different, and this without changing the frame. Indeed, as we see in figures 2a to 2d , the boxes 8a and 8b can have different lengths to receive more or less boxes 10. The frame 11 therefore makes it possible to give a certain modularity to the architecture of the turret.

Les figures 4a et 4b montrent en perspective une caisse 10 destinée à être positionnée dans un des caissons 8a ou 8b.The figures 4a and 4b show in perspective a box 10 intended to be positioned in one of the boxes 8a or 8b.

Cette caisse 10 est sensiblement parallélépipédique et elle comprend deux parois frontales 19a et 19b qui sont parallèles entre elles. La caisse 10 comporte aussi deux parois latérales 20a et 20b qui sont parallèles entre elles et qui sont aussi perpendiculaires aux parois frontales 19a et 19b.This body 10 is substantially parallelepipedic and it comprises two front walls 19a and 19b which are parallel to each other. The box 10 also comprises two side walls 20a and 20b which are parallel to each other and which are also perpendicular to the front walls 19a and 19b.

Comme on le voit sur les figures 4a et 4b, les parois frontales 19a et 19b ont toutes deux une hauteur qui est inférieure à celle des parois latérales 20a et 20b. Une telle disposition permet à la bande 21 de munitions 22 de sortir de la caisse 10 au-dessus des parois frontales 19a et 19b, alors que la bande 21 se trouve toujours maintenue transversalement par les parois latérales 20a et 20b.As seen on the figures 4a and 4b , the front walls 19a and 19b both have a height which is lower than that of the side walls 20a and 20b. Such an arrangement allows strip 21 of ammunition 22 to exit box 10 above front walls 19a and 19b, while strip 21 is still held transversely by side walls 20a and 20b.

Il est ainsi possible de relier différentes caisses 10 les unes aux autres en reliant entre elles les différentes bandes 21 qui sont contenues dans chaque caisse. La figure 4d montre ainsi schématiquement cinq caisses 101, 102, 103, 104 et 105 positionnées les unes à côté des autres dans un caisson 8a, et dont les bandes 21 sont reliées les unes aux autres, permettant l'alimentation sans heurt de l'arme. La fermeture du couvercle 17 du caisson 8a ne gêne pas la progression de la bande 21 d'une caisse à l'autre et jusqu'à l'arme. Grâce à l'accès au volume interne du caisson qui est donné par le couvercle 17, il est possible grâce à l'invention de raccorder la bande 21 d'une caisse à l'autre en sautant une ou plusieurs caisses. Inversement, il est aussi possible de réaliser un recomplètement partiel d'une caisse 10, directement par la partie supérieure des caisses, sans retirer une caisse. Ceci est plus particulièrement intéressant lorsqu'une caisse se trouve détruite. Il est possible alors de raccorder la bande de munitions d'une caisse à la suivante en évitant la caisse détruite. Il est possible aussi de remplacer la caisse détruite par une nouvelle caisse et de relier cette dernière à la bande de munitions, en amont et en aval de cette nouvelle caisse.It is thus possible to connect different cases 10 to each other by connecting together the different strips 21 which are contained in each case. The 4d figure thus schematically shows five boxes 10 1 , 10 2 , 10 3 , 10 4 and 10 5 positioned next to each other in a box 8a, and whose strips 21 are connected to each other, allowing the smooth feeding of tear. Closing the lid 17 of the box 8a does not interfere with the progression of the band 21 from one box to another and up to the weapon. Thanks to the access to the internal volume of the box which is given by the lid 17, it is possible thanks to the invention to connect the strip 21 from one box to another by skipping one or more boxes. Conversely, it is also possible to carry out a partial replenishment of a box 10, directly from the upper part of the boxes, without removing a box. This is particularly interesting when a crate is destroyed. It is then possible to connect the strip of ammunition from one crate to the next, avoiding the destroyed crate. It is also possible to replace the destroyed crate with a new crate and connect the latter to the ammunition strip, upstream and downstream of this new crate.

Comme on le voit aussi sur les figures 4a et 4b, la caisse 10 comporte un rouleau 25 qui est positionné au niveau d'une paroi frontale 19a ou 19b. Ce rouleau 25 est porté par une anse 42 pivotante comportant deux bras 26 qui sont articulés sur les parois latérales 20a et 20b. L'anse 42 formée par le rouleau 25 et les bras 26 forme ainsi une poignée permettant l'extraction de la caisse 10 hors du caisson 8a ainsi que le transport de la caisse 10. Lorsque l'anse est rabattue, comme montré à la figure 4a, l'axe 27 du rouleau est en appui contre une échancrure 24 de chaque paroi latérale 20a,20b et le rouleau 25 peut librement tourner sur son axe 27. On pourra prévoir un montage du rouleau 25 sur roulement à aiguilles pour faciliter ce pivotement. Le rouleau 25 permet de guider la bande 21 entre une caisse et sa voisine tout en réduisant les frottements. Ainsi, comme on le voit sur les figures 4d et 5, la bande glisse sans aspérités d'une caisse 10 à l'autre.As we also see on the figures 4a and 4b , the body 10 comprises a roller 25 which is positioned at a front wall 19a or 19b. This roller 25 is carried by a pivoting handle 42 comprising two arms 26 which are articulated on the side walls 20a and 20b. Cove 42 formed by the roller 25 and the arms 26 thus form a handle allowing the extraction of the box 10 from the box 8a as well as the transport of the box 10. When the handle is folded down, as shown in figure 4a , the axis 27 of the roller bears against a notch 24 of each side wall 20a, 20b and the roller 25 can freely rotate on its axis 27. It is possible to provide a mounting of the roller 25 on a needle bearing to facilitate this pivoting. The roller 25 makes it possible to guide the strip 21 between a crate and its neighbor while reducing friction. Thus, as seen in the 4d figures and 5 , the strip slides smoothly from one box 10 to another.

La caisse 10 comporte également un renfoncement 34 au niveau de la partie inférieure d'une paroi frontale 19a.The body 10 also includes a recess 34 at the level of the lower part of a front wall 19a.

Ce renfoncement 34 est plus clairement visible à la figure 4c. Il est délimité à l'avant par un bec 35 solidaire de la face inférieure. Ce bec 35 permet de faciliter l'extraction manuelle d'une caisse par l'ouverture arrière 9a ou 9b.This recess 34 is more clearly visible at the figure 4c . It is delimited at the front by a spout 35 secured to the underside. This spout 35 facilitates the manual extraction of a box through the rear opening 9a or 9b.

Comme on le voit aux figures 1b et 1c, chaque caisson 8a et 8b comporte une porte 28 qui est disposée au niveau de sa partie arrière. La porte 28 vient obturer l'ouverture 9a ou 9b que le caisson 8a ou 8b comporte au niveau de son extrémité arrière.As we see at figure 1b and 1 C , each box 8a and 8b comprises a door 28 which is arranged at its rear part. The door 28 closes the opening 9a or 9b that the box 8a or 8b has at its rear end.

Par ailleurs, la tourelle comporte au moins un plateau 29 qui est disposé derrière le caisson 8a ou 8b. Ce plateau 29 permet de recevoir une caisse 10 avant son introduction dans le caisson 8a ou 8b. Ce plateau 29 est plus particulièrement visible aux figures 1c et 7.Furthermore, the turret comprises at least one plate 29 which is arranged behind the box 8a or 8b. This plate 29 makes it possible to receive a box 10 before its introduction into the box 8a or 8b. This plate 29 is more particularly visible to figure 1c and 7 .

Ainsi la configuration de la tourelle selon l'invention permet de recevoir un nombre relativement important de caisses à munitions sous une architecture légère et compacte.Thus the configuration of the turret according to the invention makes it possible to receive a relatively large number of ammunition boxes under a light and compact architecture.

Comme on peut le voir aux figures 3b et 4d, le caisson de droite 8a peut recevoir cinq caisses 10. Trois caisses sont introduites dans le caisson 8a par son ouverture supérieure, après basculement du couvercle 17. L'opérateur peut aisément raccorder les bandes les unes aux autres pour conduire la bande 21 de munitions vers une étoile d'alimentation (non représentée) de l'arme, étoile qui se situe au voisinage de la douille 5 et qui guide la bande vers les couloirs 7a et 7b (visibles à la figure 1b).As can be seen at figure 3b and 4d , the box on the right 8a can receive five boxes 10. Three boxes are introduced into the box 8a through its upper opening, after tilting the lid 17. The operator can easily connect the strips to each other to lead the strip 21 of ammunition to a feed star (not shown) of the weapon, star which is located in the vicinity of the socket 5 and which guides the strip to the corridors 7a and 7b (visible at figure 1b ).

Les caisses 101, 102 et 103 sont maintenues par rapport au caisson 8a par un moyen de verrouillage qui comprend, d'une part les entretoises 16 qui traversent le caisson 8a et relient ses deux parois latérales, et d'autre part le couvercle supérieur 17 fermant le caisson 8a.The boxes 10 1 , 10 2 and 10 3 are held relative to the casing 8a by a locking means which comprises, on the one hand the spacers 16 which pass through the casing 8a and connect its two side walls, and on the other hand the upper cover 17 closing the box 8a.

Comme on le voit plus particulièrement sur la figure 6, le couvercle 17 comporte ainsi des rebords 17a et 17b qui viennent bloquer les bords supérieurs des parois latérales 20a,20b de chaque caisse. La figure 6 est une vue partielle qui montre en coupe transversale la partie haute du caisson de droite 8a. La coupe est réalisée au niveau d'un rouleau 25 d'une caisse 10. On voit donc sur cette figure que le couvercle 17 a une section en U et comporte des rebords avant 17a et arrière 17b qui viennent en appui contre les bords supérieurs des parois latérales 20a et 20b de la caisse 10. Grâce à ces rebords avant 17a et arrière 17b, le couvercle 17 assure bien ainsi une immobilisation des caisses 10 suivant une direction verticale. On voit aussi sur la figure 6 la charnière 18 du couvercle 17.As we see more particularly on the figure 6 , the cover 17 thus comprises flanges 17a and 17b which block the upper edges of the side walls 20a, 20b of each box. The figure 6 is a partial view which shows in cross section the upper part of the right box 8a. The cut is made at the level of a roller 25 of a box 10. It can therefore be seen in this figure that the cover 17 has a U-shaped section and comprises front 17a and rear 17b edges which bear against the upper edges of the side walls 20a and 20b of the box 10. Thanks to these front 17a and rear 17b edges, the cover 17 thus ensures that the boxes 10 are immobilized in a vertical direction. We also see on the figure 6 the hinge 18 of the cover 17.

Le couvercle 17 est bloqué en position fermée par des grenouillères 40. Il y a deux grenouillères de verrouillage 40 qui sont aussi visibles sur la figure 3b. Le couvercle 17 porte une poignée 39 permettant son ouverture et qui n'est représentée qu'à la figure 1c. On voit à la figure 6 que le couvercle 17 délimite un volume interne 41 au-dessus des caisses 10. Ce volume permet le déplacement de la bande 21 de munitions sans gêne, d'une caisse à sa voisine, et jusqu'aux couloirs d'alimentation 7a ou 7b de l'arme.The cover 17 is locked in the closed position by toggles 40. There are two locking toggles 40 which are also visible on the figure 3b . The cover 17 carries a handle 39 enabling it to be opened and which is only shown at figure 1c . We see at the figure 6 that the cover 17 delimits an internal volume 41 above the boxes 10. This volume allows the movement of the strip 21 of ammunition without hindrance, from one box to its neighbor, and up to the supply corridors 7a or 7b of tear.

L'ouverture arrière 9a du caisson 8a permet l'introduction dans le caisson 8a de deux autres caisses 104 et 105. Ces caisses sont mises en place par un opérateur situé à l'arrière de la tourelle et qui est donc protégé par les blindages 15a,15b,31 de cette dernière.The rear opening 9a of box 8a allows the introduction into box 8a of two other boxes 10 4 and 10 5 . These boxes are put in place by an operator located at the rear of the turret and who is therefore protected by the shields 15a, 15b, 31 of the latter.

Comme on le voit à la figure 5, les bandes 21 de munitions 22 qui sont dans chaque caisse 10 sont reliées les unes aux autres. Les liaisons sont réalisées après mise en place des caisses 10 dans le caisson considéré. Pour ce qui concerne le caisson de droite 8a, les bandes sont reliées au travers de l'ouverture supérieure du caisson 8a avant fermeture du couvercle 17.As we see at the figure 5 , the bands 21 of ammunition 22 which are in each box 10 are connected to each other. The connections are made after the boxes 10 have been placed in the box in question. As regards the box on the right 8a, the strips are connected through the upper opening of the box 8a before closing the cover 17.

Après mise en place des différentes caisses 10, il y a donc opérationnellement une bande de munitions 21 unique qui relie toutes les caisses 10. Lorsque l'on souhaite réapprovisionner le magasin 6a, on peut extraire une ou plusieurs caisses 10 du caisson 8a après avoir ouvert le couvercle 17.After setting up the various boxes 10, there is therefore operationally a single ammunition strip 21 which connects all the boxes 10. When it is desired to restock the store 6a, one or more boxes 10 can be extracted from the box 8a after open the lid 17.

Si l'approvisionnement doit être effectué sous le feu de l'ennemi, il est possible d'ouvrir la porte arrière 28 pour accéder aux deux caisses 104 et 105 qui sont extractibles par l'arrière du caisson 8a. On opérera un tel rechargement avant que toute la bande 21 ait été consommée. Il est alors aisé de récupérer par l'ouverture arrière 9a l'extrémité de la bande 21 pour la rattacher à la bande des munitions contenues dans les nouvelles caisses.If the supply has to be carried out under enemy fire, it is possible to open the rear door 28 to access the two boxes 10 4 and 10 5 which can be extracted from the rear of the box 8a. Such a reloading will be carried out before the entire band 21 has been consumed. It is then easy to recover through the rear opening 9a the end of the strip 21 to attach it to the strip of ammunition contained in the new cases.

Les caisses arrières 104 et 105 sont immobilisées axialement par l'appui de la caisse 104 sur la caisse 103 et l'appui de la porte 28 sur la caisse 105, porte qui forme ainsi une partie des moyens de verrouillage de ces caisses.The rear boxes 10 4 and 10 5 are immobilized axially by the support of the box 10 4 on the box 10 3 and the support of the door 28 on the box 10 5 , door which thus forms part of the locking means of these boxes.

Par ailleurs la porte 28 (voir la figure 7) comportera un ou deux verrous 36, par exemple des verrous comportant chacun une tige 36a poussée par un ressort 36b et qui s'engage dans un collier 37 (ou un perçage) porté par une paroi du caisson 8a ou 8b. Les caisses 104 et 105 sont immobilisées transversalement par les parois latérales du caisson 8a ou 8b.In addition door 28 (see the figure 7 ) will comprise one or two latches 36, for example latches each comprising a rod 36a pushed by a spring 36b and which engages in a collar 37 (or a bore) carried by a wall of the box 8a or 8b. The boxes 10 4 and 10 5 are immobilized transversely by the side walls of the box 8a or 8b.

Elles sont enfin immobilisées verticalement grâce à deux rails guides 34 (voir la figure 7) qui sont solidaires de chacune des parois latérales du caisson 8a ou 8b. Ces rails 34 forment un moyen de guidage pour les bords supérieurs des parois latérales 20a et 20b de la caisse 10 lorsqu'elle est introduite par l'ouverture arrière 9a ou 9b.They are finally immobilized vertically thanks to two guide rails 34 (see the figure 7 ) which are integral with each of the side walls of the box 8a or 8b. These rails 34 form a guide means for the upper edges of the side walls 20a and 20b of the box 10 when it is introduced through the rear opening 9a or 9b.

Le caisson de gauche 8b ne renferme que deux caisses et il est donc toujours alimenté par l'ouverture arrière 9b fermée par une porte.The left box 8b contains only two boxes and it is therefore always supplied by the rear opening 9b closed by a door.

A titre d'alimentation complémentaire, il est possible de prévoir une sixième caisse (non représentée mais notée 106) pour le caisson 8a (ou une troisième caisse pour le caisson 8b), caisse supplémentaire qui restera positionnée sur le plateau arrière 29 et qui pourra être coiffée d'un couvercle de protection (non représenté).As an additional power supply, it is possible to provide a sixth box (not shown but denoted 10 6 ) for the box 8a (or a third box for the box 8b), an additional box which will remain positioned on the rear plate 29 and which may be topped with a protective cover (not shown).

La porte 28 reste alors ouverte et on prévoira un moyen de verrouillage de cette caisse supplémentaire par rapport au plateau, par exemple une grenouillère s'engageant dans le bec 35 de la partie inférieure de la caisse 106.The door 28 then remains open and a means of locking this additional box with respect to the plate will be provided, for example a latch engaging in the spout 35 of the lower part of the box 10 6 .

Différentes variantes sont possibles sans sortir du cadre de l'invention.Different variants are possible without departing from the scope of the invention.

On pourra ainsi définir une tourelle dans laquelle les deux caissons 8a et 8b comportent chacun un couvercle et un certain nombre de caisses qui peuvent être mises en place par l'ouverture supérieure du caisson. D'autres caisses étant par ailleurs mises en place par l'ouverture arrière.It will thus be possible to define a turret in which the two boxes 8a and 8b each comprise a cover and a certain number of boxes which can be put in place through the upper opening of the box. Other crates are also put in place through the rear opening.

On pourra également concevoir une tourelle allégée dans laquelle chaque caisson 8a et 8b ne comporte qu'une ouverture arrière. Les caisses sont alors toujours mises en place par l'arrière de la tourelle. Ce mode de réalisation ne comprend qu'un nombre limité de caisses, trois au maximum par caisson.It is also possible to design a lightened turret in which each box 8a and 8b has only one rear opening. The crates are then always put in place from the rear of the turret. This embodiment only comprises a limited number of boxes, three at most per box.

Dans la tourelle selon l'invention, les douilles 5 recevant les tourillons de l'arme s'étendent au-dessus des caissons 8a et 8b recevant les munitions. Les tourillons pourront avantageusement s'étendre jusqu'à l'extrémité externe des douilles et on pourra fixer un organe (par exemple un moyen de visée) à l'extrémité des tourillons. Le moyen de visée suivra alors les mouvements de pointage de l'arme. Il sera avantageux de prévoir un dispositif de fixation amovible de ce moyen de visée, par exemple un arbre cannelé retenu pas un écrou vissé.In the turret according to the invention, the sockets 5 receiving the pins of the weapon extend above the boxes 8a and 8b receiving the ammunition. The trunnions may advantageously extend to the outer end of the sockets and a member (for example a sighting means) may be fixed to the end of the trunnions. The aiming means will then follow the aiming movements of the weapon. It will be advantageous to provide a removable fixing device for this sighting means, for example a splined shaft retained by a screwed nut.
