Description

Le domaine technique de l'invention est celui des couloirs permettant le guidage d'une bande de munitions entre un magasin et une arme.The technical field of the invention is that corridors for guiding a strip of ammunition between a store and a weapon.

Les bandes de munitions sont formées de maillons qui sont articulés les uns aux autres, chaque maillon portant une munition.The ammunition strips are formed of links that are articulated to each other, each link carrying a munition.

Ces bandes de munitions sont couramment mises en oeuvre dans les systèmes d'armes de petit calibre (calibre inférieur à 14mm) ou de moyen calibre (calibre compris entre 14mm et 50mm).These ammunition belts are commonly used in small arms systems (caliber less than 14mm) or medium caliber weapons (caliber between 14mm and 50mm).

A titre d'exemple le brevet FR2929699 décrit un type de maillons pouvant constituer une bande de munitions.For example, the patent FR2929699 describes a type of link that can constitute a band of ammunition.

Pour conduire en toute sécurité les munitions du magasin à l'arme, il est également classique de faire passer les bandes de munitions dans des couloirs d'alimentation souples qui assurent la protection et le guidage des bandes tout en autorisant les déplacements de l'arme par rapport à son affut.To safely drive ammunition from the store to the weapon, it is also standard to move the ammunition belts into flexible supply corridors that provide protection and guiding of tapes while allowing movement of the weapon. compared to his hunt.

Les couloirs connus sont généralement des ensembles complexes et coûteux formés de l'assemblage de plusieurs éléments. Chaque élément est par ailleurs lui-même formé de nombreuses pièces qu'il est nécessaire d'assembler (par vissage ou soudure) avant de constituer le couloir.Known corridors are generally complex and expensive assemblies formed by the assembly of several elements. Each element is itself formed of many parts that it is necessary to assemble (by screwing or welding) before forming the corridor.

On connaît par le brevet US3307452 un couloir pour bande de munitions dont chaque élément est formé d'une pièce de tôle unique pliée en forme de C.We know by the patent US3307452 a gangway for ammunition strips, each element of which is formed of a piece of single folded C-shaped sheet metal.

Cet élément présente une structure pliée complexe et par ailleurs la forme ouverte de chaque élément le rend particulièrement déformable, risquant de détériorer le guidage. Il en résulte un risque de blocage de la bande dans le couloir.This element has a complex folded structure and also the open form of each element makes it particularly deformable, risking deterioration of the guide. This results in a risk of blockage of the strip in the corridor.

On connaît aussi par le brevet GB590783 un couloir formé par l'assemblage d'éléments individuels de deux types différents : des barres en forme de C et des cadres fermés. Les éléments sont liées deux à deux par des goupilles et des moyens ressort sont interposés entre deux éléments consécutifs. Là encore ce couloir formé de plusieurs pièces différentes est complexe et coûteux.Also known by the patent GB590783 a corridor formed by the assembly of individual elements of two different types: C-shaped bars and closed frames. The elements are linked two by two by pins and spring means are interposed between two consecutive elements. Here again this corridor formed of several different parts is complex and expensive.

L'invention a pour but de proposer un élément permettant par assemblage avec d'autres éléments de réaliser un couloir de guidage de bandes de munitions, élément qui soit de fabrication facile et peu coûteuse et dont la rigidité assure le guidage fiable de la bande de munitions.The object of the invention is to propose an element which, by assembly with other elements, makes it possible to produce an ammunition strip guide lane, an element which is easy to manufacture and inexpensive and whose rigidity ensures the reliable guiding of the strip of ammunition.

Ainsi l'invention a pour objet un élément d'un couloir qui est destiné à guider une bande de munitions formée de maillons portant des munitions entre un magasin et une arme, élément formé d'une seule pièce et comportant des moyens permettant la solidarisation de l'élément avec au moins un autre élément pour constituer un couloir, élément caractérisé en ce qu'il est constitué par une plaque ayant un contour fermé sensiblement rectangulaire comprenant deux côtés longs reliés par deux côtés courts et délimitant un passage pour la bande de munitions, les moyens permettant la solidarisation avec un autre élément comprenant au moins deux paires de languettes s'étendant sensiblement perpendiculairement à la plaque, languettes destinées à s'insérer dans des encoches portées par un élément voisin, une première paire de languettes étant disposée au niveau d'un premier côté long du contour rectangulaire et la deuxième paire de languettes étant disposée au niveau d'un deuxième côté long du contour qui est parallèle au premier côté long.Thus, the subject of the invention is an element of a corridor which is intended to guide a strip of ammunition formed of links bearing ammunition between a magazine and a weapon, an element formed in one piece and comprising means enabling the fastening of the element with at least one other element to constitute a corridor, characterized in that it consists of a plate having a substantially rectangular closed contour comprising two long sides connected by two short sides and delimiting a passage for the ammunition strip , the means for securing with another element comprising at least two pairs of tongues extending substantially perpendicularly to the plate, tongues intended to fit into notches carried by a neighboring element, a first pair of tongues being arranged at the a first long side of the rectangular outline and the second pair of tabs being disposed at a u level of a second long side of the contour which is parallel to the first long side.

Avantageusement, chaque languette pourra comporter un bec formant une butée limitant l'écartement relatif de l'élément par rapport à un élément voisin.Advantageously, each tongue may comprise a beak forming an abutment limiting the relative spacing of the element relative to a neighboring element.

Chaque languette pourra être reliée au côté long du contour considéré par un pied de raccordement formant une surface d'appui pour les maillons de la bande de munitions.Each tongue may be connected to the long side of the contour considered by a connecting leg forming a bearing surface for the links of the ammunition strip.

Avantageusement, la plaque pourra comporter des moyens permettant un guidage transversal de la bande de munitions.Advantageously, the plate may comprise means for transverse guidance of the ammunition strip.

Les moyens permettant le guidage transversal de la bande de munition pourront comprendre deux barrettes s'étendant sensiblement perpendiculairement à la plaque, une première barrette étant disposée au niveau d'un premier côté court du contour et étant destinée à former un guide pour les culots des munitions de la bande, une seconde barrette étant disposée au niveau d'un côté long du contour et étant destinée former une butée pour une partie avant du maillon de la bande.The means for transverse guidance of the ammunition strip may comprise two bars extending substantially perpendicular to the plate, a first strip being disposed at a first short side of the contour and being intended to form a guide for the caps of the ammunition of the strip, a second strip being disposed at a long side of the contour and being intended to form a stop for a front portion of the link of the strip.

Chaque côté long du contour rectangulaire de la plaque pourra comporter un rebord courbe s'écartant d'une partie plane de la plaque.Each long side of the rectangular contour of the plate may comprise a curved rim deviating from a flat portion of the plate.

Chaque élément du couloir pourra être réalisé en tôle découpée et pliée.Each corridor element can be made of sheet metal cut and folded.

Selon un autre mode de réalisation, l'invention vise un élément d'un couloir qui est destiné à guider une bande de munitions formée de maillons portant des munitions entre un magasin et une arme, élément formé d'une seule pièce et comportant des moyens permettant la solidarisation de l'élément avec au moins un autre élément pour constituer un couloir, cet élément étant caractérisé en ce qu'il est constitué par une plaque ayant un contour sensiblement rectangulaire et ouvert comprenant deux côtés longs reliés par deux côtés courts et délimitant un passage pour la bande de munitions, les moyens permettant la solidarisation avec un autre élément comprenant au moins deux paires de languettes s'étendant sensiblement perpendiculairement à la plaque, languettes destinées à s'insérer dans des encoches portées par un élément voisin, une première paire de languettes étant disposée au niveau d'un premier côté long du contour rectangulaire et la deuxième paire de languettes étant disposée au niveau d'un deuxième côté long du contour qui est parallèle au premier côté long.According to another embodiment, the invention relates to an element of a corridor which is intended to guide an ammunition strip formed of links carrying ammunition between a magazine and a weapon, a element formed in one piece and comprising means allowing the element to be secured to at least one other element in order to constitute a corridor, this element being characterized in that it consists of a plate having a substantially rectangular and open contour comprising two long sides connected by two short sides and delimiting a passage for the ammunition strip, the means for securing with another element comprising at least two pairs of tongues extending substantially perpendicularly to the plate, tabs intended to fit into notches carried by a neighboring element, a first pair of tongues being disposed at a first long side of the rectangular contour and the second pair of tongues being disposed at a second long side of the contour which is parallel to the first long side.

En se reportant à la figure 1, un système d'arme 1 de moyen calibre (compris entre 14mm et 50mm) comporte une arme 2 qui a un tube 3 et dont le berceau 2a est monté oscillant sur des tourillons 4 d'axe 5. Le système d'arme 1 comporte aussi un magasin de munitions 6 qui est solidaire d'une tourelle (non représentée) qui porte aussi le berceau 2a par l'intermédiaire d'une fourche non représentée.Referring to the figure 1 a weapon system 1 of medium caliber (between 14mm and 50mm) comprises a weapon 2 which has a tube 3 and whose cradle 2a is pivotally mounted on pins 4 of axis 5. The weapon system 1 comprises also an ammunition store 6 which is secured to a turret (not shown) which also carries the cradle 2a via a not shown fork.

Cette représentation est très schématique et a pour seul but de positionner un couloir de guidage 7 selon l'invention.

The strip 8 is wound in the magazine 6. This strip of ammunition is not subject of the invention and need not be described in detail. Patent applications FR2929699 and FR1357412 describe examples of links forming a strip of ammunition.

Le couloir de guidage 7 selon l'invention est formé de l'assemblage d'éléments individuels 11 tous identiques les uns aux autres.The guide corridor 7 according to the invention is formed of the assembly of individual elements 11 all identical to each other.

La figure 2 montre en perspective un de ces éléments individuels 11.The figure 2 shows in perspective one of these individual elements 11.

L'élément 11 est constitué par un élément formé d'une seule pièce qui est une plaque 11a sensiblement plane ayant un contour fermé sensiblement rectangulaire comprenant deux côtés longs 11b et 11c qui sont reliés par deux côtés courts 11d et 11e. Le contour fermé délimite un passage 13 pour la bande de munitions.The element 11 is constituted by a one-piece element which is a substantially planar plate 11a having a substantially rectangular closed contour comprising two long sides 11b and 11c which are connected by two short sides 11d and 11e. The closed contour delimits a passage 13 for the ammunition strip.

La réalisation de l'élément 11 sous la forme d'un contour fermé permet d'obtenir une forte rigidité de cet élément et réduit ses déformations de flexion en réponse à un effort F parallèle au plan de la plaque 11a. Il en résulte un guidage des bandes de munitions sans risque de blocage comme suite à une déformation des éléments 11 du couloir.The embodiment of the element 11 in the form of a closed contour makes it possible to obtain a high rigidity of this element and reduces its flexural deformations in response to a force F parallel to the plane of the plate 11a. This results in a guide of the ammunition strips without risk of blockage as a result of deformation of the elements 11 of the corridor.

Comme on le voit sur la figure 2 la plaque 11a forme une surface plane et chaque côté long 11b et 11c du contour rectangulaire de la plaque comporte un rebord courbe 14 qui s'écarte sensiblement de la partie plane de la plaque 11a. Une telle disposition permet d'augmenter la rigidité en flexion de la plaque 11a en réponse à l'effort F. Elle évite aussi les angles vifs pouvant blesser les utilisateurs lors de la mise en place des couloirs.As we see on the figure 2 the plate 11a forms a flat surface and each long side 11b and 11c of the rectangular contour of the plate has a curved flange 14 which substantially deviates from the flat portion of the plate 11a. Such an arrangement makes it possible to increase the bending rigidity of the plate 11a in response to the force F. It also avoids the sharp angles that can injure the users during the installation of the corridors.

Comme on le voit également à la figure 2, la plaque 11a comporte aussi deux paires 15a, 15b de languettes 16 qui s'étendent sensiblement perpendiculairement à la plaque 11a.As we also see at figure 2 the plate 11a also has two pairs 15a, 15b of tabs 16 which extend substantially perpendicular to the plate 11a.

Une première paire 15a de languettes 16 est disposée au niveau d'un premier côté long 11b du contour rectangulaire et la deuxième paire 15b de languettes 16 est disposée au niveau d'un deuxième côté long 11c du contour qui est parallèle au premier côté long.A first pair 15a of tabs 16 is disposed at a first long side 11b of the rectangular contour and the second pair 15b of tabs 16 is disposed at a second long side 11c of the contour which is parallel to the first long side.

Chaque languette 16 est reliée au côté long 11b ou 11c du contour considéré par un pied de raccordement 17 élargi qui est destiné à former une surface d'appui pour les maillons 9 de la bande de munitions.Each tongue 16 is connected to the long side 11b or 11c of the contour considered by an enlarged connecting leg 17 which is intended to form a bearing surface for the links 9 of the ammunition strip.

La figure 3 montre une munition 10 solidaire d'un maillon 9. On remarque que le maillon 9 est guidé longitudinalement par les quatre portées formées par les pieds de raccordement 17.The figure 3 shows a munition 10 integral with a link 9. Note that the link 9 is guided longitudinally by the four spans formed by the connecting feet 17.

Il est facile de maitriser lors de la fabrication des éléments 11 les écartements entre les pieds de raccordement 17 des deux paires de languettes 16. Le jeu entre le maillon et chaque élément du couloir est donc aisément maîtrisable.It is easy to master during the manufacture of elements 11 the spacings between the connecting feet 17 of the two pairs of tongues 16. The clearance between the link and each element of the corridor is easily controllable.

On remarque sur la figure 2 que chaque pied de raccordement 17 comporte une encoche 18.We notice on the figure 2 each connecting leg 17 has a notch 18.

Les languettes 16 d'un élément 11 donné sont destinées à s'insérer dans les encoches 18 qui sont portées par un élément 11 voisin.The tabs 16 of a given element 11 are intended to fit into the notches 18 which are carried by a neighboring element 11.

Languettes 16 et encoches 18 constituent ainsi des moyens permettant la solidarisation d'un élément 11 avec un ou deux éléments voisins. Chaque languette 16 enfin comporte un bec 19 qui est replié à angle droit par rapport à la languette 16. Le bec 19 forme une butée qui permet de limiter l'écartement relatif d'un élément 11 par rapport à un élément voisin.Tabs 16 and notches 18 thus constitute means for securing an element 11 with one or two neighboring elements. Each tab 16 finally has a spout 19 which is folded at right angles to the tongue 16. The spout 19 forms a stop which limits the relative spacing of an element 11 relative to a neighboring element.

Si on considère en particulier la figure 5 qui montre l'assemblage de plusieurs éléments 11 (ici cinq éléments) pour former un couloir 7, on voit que chaque languette 16 est engagée dans une encoche 18 d'un élément voisin. Cet assemblage autorise l'écartement et le rapprochement des éléments 11 les uns des autres jusqu'à mise en butée d'un ou de plusieurs becs 19 contre la plaque 11a d'un élément voisin. En particulier sur la figure 5 on remarque que l'élément 11 situé le plus à droite a une languette 16 supérieure dont le bec 19 est en butée contre l'élément 11 voisin alors que la languette 16 inférieure n'est pas en butée. Il y a un pivotement relatif possible de ces éléments 11 les uns par rapport aux autres, ce qui permet au couloir de suivre des parcours courbes.If we consider in particular the figure 5 which shows the assembly of several elements 11 (here five elements) to form a corridor 7, we see that each tab 16 is engaged in a notch 18 of a neighboring element. This assembly allows the spacing and approximation of the elements 11 from each other until abutment of one or more nozzles 19 against the plate 11a of a neighboring element. In particular on the figure 5 it is noted that the element 11 located at the rightmost has an upper tongue 16 whose spout 19 abuts against the adjacent element 11 while the lower tongue 16 is not in abutment. There is a possible relative pivoting of these elements 11 relative to each other, which allows the corridor to follow curved paths.

On pourra également prévoir un jeu entre les languettes 16 et les encoches 18 qui autorisera un pivotement d'un élément 11 par rapport à ses voisins autour d'un axe perpendiculaire au plan de la plaque 11a. On autorise ainsi une torsion limitée du couloir 7, ce qui peut être utile pour certains types de montages d'armes.It will also be possible to provide a clearance between the tongues 16 and the notches 18 which will allow pivoting of an element 11 relative to its neighbors around an axis perpendicular to the plane of the plate 11a. This allows a limited torsion of the corridor 7, which may be useful for certain types of weapons mounting.

La figure 4 montre le même assemblage de cinq éléments 11 suivant un autre angle de vision. En considérant les deux éléments 11 situés les plus à gauche, on peut voir sur la figure 4 les engagements des languettes 16 dans les encoches 18. On remarque aussi sur cette figure 4 que les pieds de raccordement 17 des différentes languettes se situent après montage sensiblement dans le prolongement les uns des autres. Le guidage des maillons 9 de la bande de munitions se fait donc de façon continue tout le long du couloir 7 malgré les pivotements relatifs des éléments 11 les uns par rapport aux autres.The figure 4 shows the same assembly of five elements 11 according to another angle of vision. Considering the two elements 11 located furthest to the left, we can see on the figure 4 the commitments of the tabs 16 in the notches 18. Note also on this figure 4 that the connecting feet 17 of the various tabs are located after mounting substantially in the extension of each other. The guidance of the links 9 of the ammunition strip is therefore continuous along the entire corridor 7 despite the relative pivoting elements 11 relative to each other.

En se reportant à la figure 2, la plaque 11 comporte aussi d'autres moyens permettant un guidage transversal de la bande de munitions.Referring to the figure 2 , the plate 11 also comprises other means for transverse guidance of the ammunition strip.

Ces moyens de guidage comprennent deux barrettes 20 et 21 qui s'étendent sensiblement perpendiculairement à la plaque 11a.These guide means comprise two bars 20 and 21 which extend substantially perpendicular to the plate 11a.

Une première barrette 20 est disposée au niveau d'un premier côté court 11d du contour et elle est destinée à former un guide transversal pour les culots 10a des munitions 10 de la bande. Les culots 10a des munitions sont en appui (ou en regard) contre un rebord 20a de cette première barrette disposé du côté de l'ouverture 13.A first bar 20 is disposed at a first short side 11d of the contour and is intended to form a transverse guide for the pellets 10a of the ammunition 10 of the strip. The pellets 10a of the ammunition are supported (or facing) against a flange 20a of this first bar disposed on the side of the opening 13.

Comme on le voit sur la figure 5, les premières barrettes 20 sont suffisamment longues pour que le culot 10a de la munition soit toujours en appui (ou en regard) contre une barrette 20 au cours de sa progression dans le couloir 7.As we see on the figure 5 , the first bars 20 are sufficiently long so that the base 10a of the ammunition is always in support (or facing) against a bar 20 during its progression in the corridor 7.

Une seconde barrette 21 est disposée au niveau du second côté long 11c du contour de l'élément 11 et elle est destinée à former une butée pour une partie avant 9a du maillon 9.A second bar 21 is disposed at the second long side 11c of the contour of the element 11 and is intended to form a stop for a front portion 9a of the link 9.

La seconde barrette 21 empêche donc le déplacement transversal de la bande de munitions qui reste positionnée entre la première barrette 20 et la seconde barrette 21. Les deux barrettes assurent donc ainsi un positionnement transversal des munitions qui ne se positionnent pas en travers dans le couloir 7.The second bar 21 thus prevents the transverse displacement of the ammunition strip which remains positioned between the first bar 20 and the second bar 21. The two bars thus provide a transverse positioning of the ammunition which does not position crosswise in the corridor 7 .

Du point de vue fabrication, les éléments 11 sont réalisés par découpe laser ou poinçonnage dans une plaque d'acier inoxydable de 1 à 2 mm d'épaisseur. La figure 6 montre le profil de découpe qui est réalisé sur chaque plaque. Chaque élément est donc réalisé d'une seule pièce ce qui est particulièrement économique.From the manufacturing point of view, the elements 11 are made by laser cutting or punching in a stainless steel plate 1 to 2 mm thick. The figure 6 shows the cutting profile that is made on each plate. Each element is made in one piece which is particularly economical.

Après découpe, tous les plis sont d'abord réalisés à l'aide d'un outil adapté (plieuse, outil d'emboutissage...).After cutting, all the folds are first made using a suitable tool (folder, stamping tool ...).

Le montage se fait en plaçant les languettes 16 de la seconde paire 15b d'un élément 11 en position dans les encoches 18 d'un autre élément 11 de couloir. On appuie ensuite sur les languettes 16 de la première paire 15a pour les placer par déformation élastique dans les encoches 18 correspondantes de l'autre élément de couloir.The assembly is done by placing the tongues 16 of the second pair 15b of an element 11 in position in the notches 18 of another corridor element 11. Then press the tabs 16 of the first pair 15a to place them by elastic deformation in the corresponding notches 18 of the other corridor element.

On assemble ainsi les éléments les uns aux autres jusqu'à former un couloir 7 ayant la longueur souhaitée.The elements are thus assembled together to form a corridor 7 having the desired length.

L'invention a été décrite dans une application au guidage d'une bande de munition de moyen calibre (20mm). Elle est bien entendu applicable pour réaliser des couloirs de guidage de bandes de munitions d'autres calibres, en particulier de petit calibre (inférieur à 14mm, par exemple 12,7 mm ou 7, 62mm) .The invention has been described in an application for guiding a medium-caliber ammunition strip (20mm). It is of course applicable to make ammunition strip guide corridors of other calibers, especially small caliber (less than 14mm, for example 12.7 mm or 7, 62mm).

Les figures 7a et 7b montrent en perspective un élément de couloir selon deux autres modes de réalisation de l'invention.The Figures 7a and 7b show in perspective a corridor element according to two other embodiments of the invention.

Ces modes de réalisation diffèrent du précédent en ce que la plaque 11a a un contour sensiblement rectangulaire qui est ouvert et non plus fermé.These embodiments differ from the preceding in that the plate 11a has a substantially rectangular contour which is open and no longer closed.

Ainsi, selon la figure 7a, une ouverture 22 est pratiquée au niveau du côté long supérieur 11b et entre les languettes 16 de la première paire 15a de languettes.So, according to the figure 7a an opening 22 is made at the upper long side 11b and between the tongues 16 of the first pair 15a of tabs.

Selon la figure 7b, l'ouverture 22 est pratiquée entre une languette 16 de la première paire 15a et le côté court 11e de la plaque 11a.According to figure 7b the opening 22 is made between a tongue 16 of the first pair 15a and the short side 11e of the plate 11a.

L'ouverture 22 diminue sensiblement la rigidité de l'élément mais elle autorise par contre une légère déformation par torsion de la plaque 11a autour d'une direction parallèle aux côtés longs 11b et 11c, ce qui donne au couloir réalisé une flexibilité en torsion. Par ailleurs l'ouverture 22 permet de faciliter le guidage d'une bande de munitions, avec un outil, au travers du couloir lors du chargement initial de l'arme.The opening 22 substantially reduces the rigidity of the element but it allows against a slight deformation by torsion of the plate 11a around a direction parallel to the long sides 11b and 11c, which gives the corridor made flexibility in torsion. In addition, the opening 22 makes it easier to guide an ammunition strip, with a tool, through the passageway during the initial loading of the weapon.

L'ouverture 22 est de préférence réalisée au niveau du côté long 11b qui ne porte pas la seconde barrette de guidage 21. Ainsi la déformation en torsion de la plaque 11a ne perturbera pas le guidage de la bande de munitions qui est réalisé au niveau du côté long 11c.The opening 22 is preferably made at the long side 11b which does not bear the second guide bar 21. Thus the torsional deformation of the plate 11a does not will not interfere with the guidance of the ammunition strip which is made at the long side 11c.

La plaque 11a présente par ailleurs toutes les caractéristiques structurelles décrites précédemment en référence aux figures 2 à 6. Chaque plaque 11a est ainsi rendue solidaire de sa voisine par deux paires 15a,15b de languettes 16 qui s'étendent perpendiculairement à la plaque 11a et qui s'insèrent dans des encoches 18 portées par une plaque 11a voisine. Il est donc tout à fait possible pour décrire les caractéristiques de ces deux modes de réalisation de considérer également les figures 2 à 6 en leur adjoignant une ouverture 22 telle que décrite en référence aux figures 7a et 7b.The plate 11a also has all the structural characteristics described above with reference to the Figures 2 to 6 . Each plate 11a is thus secured to its neighbor by two pairs 15a, 15b of tabs 16 which extend perpendicularly to the plate 11a and which are inserted in notches 18 carried by a plate 11a neighbor. It is therefore quite possible to describe the characteristics of these two embodiments to also consider the Figures 2 to 6 by adding to them an opening 22 as described with reference to Figures 7a and 7b .

Là encore les plaques 11a pourront être réalisées par découpe laser ou par poinçonnage. L'ouverture 22 donne une certaine capacité de déformation en torsion de la plaque.Again plates 11a may be made by laser cutting or punching. The opening 22 gives a certain torsional deformation capacity of the plate.

Afin de limiter la déformation en flexion de la plaque comme suite à un effort F parallèle au plan de la plaque (voir figure 2) et donc pour permettre un guidage des bandes de munitions par les barrettes 20 et 21 en évitant le blocage des bandes de munitions, on pourra donner à la plaque 11a une épaisseur supérieure à celle adoptée pour le mode de réalisation précédent.In order to limit the bending deformation of the plate as a result of a force F parallel to the plane of the plate (see figure 2 ) and thus to allow a guide of the ammunition strips by the bars 20 and 21 avoiding the blocking ammunition strips, we can give the plate 11a a thickness greater than that adopted for the previous embodiment.

On pourra également prolonger les rebords courbes 14 pour réaliser un rebord courbe qui suivra, de façon continue (sauf au niveau de l'ouverture 22), tout le bord externe de la plaque 11a. Dans ce cas la plaque 11a sera par exemple emboutie après découpe pour former le rebord.It will also be possible to extend the curved flanges 14 to produce a curved flange which will follow, in a continuous manner (except at the level of the opening 22), the entire external edge of the plate 11a. In this case the plate 11a will for example be stamped after cutting to form the flange.

A titre de variante il serait possible de définir un élément 11 ayant la forme d'un contour fermé (ou ouvert) mais sur lequel les moyens de solidarisation entre éléments auraient une autre forme que les languettes pliées. Par exemple on pourrait définir des moyens de solidarisation rapportés tels que des anneaux de liaison oblongs fixés dans des perçages de deux éléments voisins. Un tel mode de réalisation permettrait de conserver la rigidité assurée par la forme fermée. Il est cependant moins intéressant économiquement car, en multipliant les pièces, on augmentera les coûts de fabrication et d'assemblage du couloir.As a variant it would be possible to define an element 11 in the form of a closed (or open) contour but on which the means for securing between elements would have a shape other than the folded tabs. For example one could define reported securing means such as oblong connection rings fixed in holes of two neighboring elements. Such an embodiment would maintain the rigidity provided by the closed form. However, it is less economically interesting because, by multiplying the parts, we will increase the costs of manufacturing and assembly of the corridor.
