Definitions
- the technical field of the invention is that of feeding devices of a munitions weapon secured to links.
- Such devices are well known and generally include one or more feed corridors driving ammunition from a storage crate to the weapon.
- One of the main problems with the feeding devices is that of facilitating the quick reloading of the weapon.
- the known devices are complex because they require moving the empty box to position the full box in the vicinity of the ammunition supply device.
- the device according to the invention makes it possible to ensure a fast reloading of a weapon, reloading can even be done without de-energizing the weapon.
- the device according to the invention also makes it possible to minimize the forces exerted on the ammunition strips.
- the subject of the invention is a device for feeding an ammunition weapon secured to links and from an ammunition box, characterized in that it comprises on the one hand at least two ammunition boxes arranged side-by-side and secured to a side wall of a carriage, and secondly an introduction corridor whose opening is disposed above the boxes and substantially at a plane separating the boxes, each box being moreover slide relative to the wall to pass, after the withdrawal of the other box, from an initial position to a final position which was the one previously occupied by the other box.
- the device may comprise two identical boxes.
- the device may comprise at least one horizontal bar attached to the side wall and on which the boxes are hooked.
- the device comprises two horizontal bars receiving the boxes, each box having hooks fixed at a rear face, hooks for cooperating with the bars.
- the device may comprise a locking means ensuring the locking of the boxes on the bars
- the locking means may include an eccentric mounting of the lower bar relative to its pivot axis.
- the introduction corridor may be pivotally mounted relative to an axis substantially perpendicular to the side wall.
- the ammunition will preferably be arranged in each box so that the first link of the band is disposed at an upper lateral edge and the last link of the band is arranged at the level of the other upper lateral edge, such that so that it is possible to connect the last link of the band of a first box to the first link of the band of a second box.
- a weapon 1 (whose barrel is here truncated and not completely visible) is pivotally mounted on journals with respect to a carriage 3 formed of a fork, itself pivoting around a vertical axis 4 relative to a base 5.
- the axis 2 of the trunnions is shown in dashed lines in the figure.
- the weapon 1 is not the object of the present invention and will not be described in detail. It is here equipped with an optronic viewfinder 6.
- This weapon 1 is a medium caliber weapon (caliber less than or equal to 50 mm). It is fed by ammunition strips.
- An ammunition strip includes links that each hold a munition, the links are hinged to each other. It is conventional to make ammunition of small or medium caliber solidarity links to facilitate the supply of the weapon. The latter then comprises a means of demaillonage (not shown) which allows to separate at the entrance of the weapon ammunition with the links.
- the ammunition is arranged in two boxes 7a and 7b arranged side by side and integral with a side wall 8 of the carriage 3.
- Each box contains a strip 11a or 11b of ammunition 9 (see Figure 3a).
- FIG. 1 shows ammunition 9 integral with links and coming out of the box 7b.
- Figure 3a shows a weapon for which the two ammunition cases 7a and 7b are packed.
- Figure 6 is an enlargement of Figure 3a showing the upper part of the boxes 7a and 7b.
- the munitions 9 are disposed in the box 7b so that the first link Ma of the strip 11b (as well as the first ammunition 9a) are placed at a level first upper lateral edge 12 of the box 7b.
- the same type of arrangement of the ammunition strip is provided in the box 7a.
- FIG. 7 shows that the strip 11b of ammunition is zigzagged to the bottom of the box 7b, while the last link Mb (as well as the last ammunition 9b) of the strip 11b are arranged at the level of the other upper side edge 13.
- the band 11b thus has a vertical part Bv which connects the bottom of the box 7b and the flange 13.
- a hook 24 allows the maintenance of this vertical part Bv during filling of the box.
- the feed device according to the invention also comprises an insertion corridor 10 which is pivotally mounted with respect to an axis substantially perpendicular to the lateral wall, which axis coincides with the axis 2 of the journals of the weapon 1.
- the introduction corridor 10 thus comprises a lower opening 10a (FIG. 2) which is disposed above the boxes 7a and 7b and substantially at the level of a vertical plane separating the two boxes.
- the introduction corridor 10 is thus substantially equidistant from each ammunition box 7a, 7b and it is possible to supply the weapon indifferently from one or other of the boxes 7a, 7b. Due to this positioning of the corridor 10 substantially at the vertical plane separating the boxes, the forces exerted on the ammunition strips are equivalent regardless of the box that provides the supply. The passage from one box to another is therefore smooth and without the need to stop shooting.
- the pivoting capacity of the passage 10 with respect to the axis 2 facilitates the guiding of the ammunition of a box towards the weapon and the coaxiality of the pivoting of the passage 10 with respect to the pivoting of the weapon on its trunnions makes it possible to ensure the supply of the weapon regardless of the orientation of it in site on its trunnions.
- Figure 2 shows the weapon ammunition cases removed.
- the side wall 8 of the carriage 3 carries two horizontal bars 15a and 15b for receiving the boxes 7a, 7b.
- the upper bar 15a is fixed while the lower bar 15b can move relative to the wall 8 by means of a locking means 18 comprising an eccentric actuated by a crank 19 (there are in fact two cranks 19, one on each side of the wall 8).
- Figure 4 shows more precisely the attachment mode of the boxes 7a, 7b on the bars 15a, 15b and the locking means 18 ensuring the locking of the boxes on the bars.
- each box 7a or 7b has at a rear face 16a, 16b hooks 17 and 17 '.
- Each box thus has two upper hooks 17 capping the upper bar 15a and two lower hooks 17 'which are open upwards and are therefore positioned below the lower bar 15b.
- These hooks 17 ' are intended to allow the locking of the boxes.
- the profiles of the hooks are chosen so as to surround the bars about 180 °.
- the crank 19 allows to manually control a pivoting of the lower bar 15b.
- the lower bar 15b is pivotally mounted relative to an axis 21 integral with the wall 8.
- the bar 15b is mounted eccentrically with respect to the axis 21.
- the pivoting of the bar 15b with respect to the axis 21 is controlled by the crank 19.
- the device is shown in the locked position in FIG. 5a. Pivoting in the DV direction will move the device to its unlocked position shown in Figure 5b. The reverse pivoting (arrow V) moves it from the unlocked position of Figure 5b to that of Figure 5a.
- each box 7a, 7b can also slide by relative to the wall 8, on the bars 15a, 15b, to indifferently occupy one or the other position of each box.
- Figure 3a shows the weapon 1 in an initial position in which it is equipped with two ammunition crates 7a and 7b loaded. As seen previously with reference to FIG. 6, it can be seen that the ammunition strip 11a of the box 7a is connected to the ammunition strip 11b of the box 7b.
- Figure 3b shows the weapon after withdrawal of the box 7a.
- the ammunition is taken from the box 7b.
- the locking means being released, it is then possible to slide the box 7b on the bar 15a in the direction D to move the box 7b from its initial position to a final position which was the one previously occupied by the box 7a.
- the weapon is then found in a configuration identical to that shown in Figure 3a: two ammunition boxes side by side each containing a strip of ammunition.
- the two strips being integral and forming only one continuous strip of ammunition 9 distributed between the two boxes.
- the two boxes are locked using the blocking means 18.
- the invention is implemented here with a medium-caliber weapon (caliber between 20 mm and 50 mm). It could of course be implemented with small weapons

Description
Le domaine technique de l'invention est celui des dispositifs d'alimentation d'une arme en munitions solidaires de maillons.The technical field of the invention is that of feeding devices of a munitions weapon secured to links.
De tels dispositifs sont bien connus et ils comportent généralement un ou plusieurs couloirs d'alimentation conduisant les munitions d'une caisse de stockage à l'arme.Such devices are well known and generally include one or more feed corridors driving ammunition from a storage crate to the weapon.
Un des principaux problèmes rencontrés avec les dispositifs d'alimentation est celui de faciliter le rechargement rapide de l'arme.One of the main problems with the feeding devices is that of facilitating the quick reloading of the weapon.
Il est connu de prévoir plusieurs caisses de munitions cependant il est généralement nécessaire d'arrêter le tir ou de désalimenter l'arme pour permettre la mise en place d'une nouvelle caisse.It is known to provide several cases of ammunition however it is usually necessary to stop shooting or de-energize the weapon to allow the establishment of a new box.

Les dispositifs connus sont complexes car ils imposent de déplacer la caisse vide pour positionner la caisse pleine au voisinage du dispositif d'alimentation en munitions.The known devices are complex because they require moving the empty box to position the full box in the vicinity of the ammunition supply device.
Le tir doit le plus souvent être interrompu lors de ce déplacement des caisses à munitions afin d'éviter des efforts excessifs au niveau des bandes de munitions.Most of the shot must be stopped when moving the ammunition boxes to avoid excessive straining of the ammunition bands.
C'est le but de l'invention que de proposer un dispositif d'alimentation permettant de pallier de tels inconvénients.It is the object of the invention to provide a feed device for overcoming such disadvantages.
Ainsi le dispositif selon invention permet d'assurer un rechargement rapide d'une arme, le rechargement pouvant même être réalisé sans désalimenter l'arme.Thus the device according to the invention makes it possible to ensure a fast reloading of a weapon, reloading can even be done without de-energizing the weapon.
Le dispositif selon l'invention permet par ailleurs de minimiser les efforts exercés sur les bandes de munitions.The device according to the invention also makes it possible to minimize the forces exerted on the ammunition strips.
Ainsi l'invention a pour objet un dispositif d'alimentation d'une arme en munitions solidaires de maillons et à partir d'une caisse à munition, dispositif caractérisé en ce qu'il comprend d'une part au moins deux caisses à munitions disposées côte à côte et solidaires d'une paroi latérale d'un affût, et d'autre part un couloir d'introduction dont une ouverture est disposée au-dessus des caisses et sensiblement au niveau d'un plan séparant les caisses, chaque caisse pouvant par ailleurs coulisser par rapport à la paroi pour passer, après le retrait de l'autre caisse, d'une position initiale à une position finale qui était celle occupée précédemment par l'autre caisse.Thus, the subject of the invention is a device for feeding an ammunition weapon secured to links and from an ammunition box, characterized in that it comprises on the one hand at least two ammunition boxes arranged side-by-side and secured to a side wall of a carriage, and secondly an introduction corridor whose opening is disposed above the boxes and substantially at a plane separating the boxes, each box being moreover slide relative to the wall to pass, after the withdrawal of the other box, from an initial position to a final position which was the one previously occupied by the other box.
Le dispositif pourra comprendre deux caisses identiques.The device may comprise two identical boxes.
Le dispositif pourra comporter au moins une barre horizontale fixée à la paroi latérale et sur laquelle s'accrochent les caisses.The device may comprise at least one horizontal bar attached to the side wall and on which the boxes are hooked.
Avantageusement, le dispositif comporte deux barres horizontales recevant les caisses, chaque caisse comportant des crochets fixés au niveau d'une face arrière, crochets destinés à coopérer avec les barres.Advantageously, the device comprises two horizontal bars receiving the boxes, each box having hooks fixed at a rear face, hooks for cooperating with the bars.
Le dispositif pourra comporter un moyen de blocage assurant le verrouillage des caisses sur les barresThe device may comprise a locking means ensuring the locking of the boxes on the bars
Le moyen de blocage pourra notamment comporter un montage excentré de la barre inférieure par rapport à son axe de pivotement.The locking means may include an eccentric mounting of the lower bar relative to its pivot axis.
Avantageusement, le couloir d'introduction pourra être monté pivotant par rapport à un axe sensiblement perpendiculaire à la paroi latérale.Advantageously, the introduction corridor may be pivotally mounted relative to an axis substantially perpendicular to the side wall.
Les munitions seront de préférence disposées dans chaque caisse de telles sorte que le premier maillon de la bande soit disposé au niveau d'un bord latéral supérieur et le dernier maillon de la bande soit disposé au niveau de l'autre bord latéral supérieur, de telle sorte qu'il soit possible de raccorder le dernier maillon de la bande d'une première caisse au premier maillon de la bande d'une deuxième caisse.The ammunition will preferably be arranged in each box so that the first link of the band is disposed at an upper lateral edge and the last link of the band is arranged at the level of the other upper lateral edge, such that so that it is possible to connect the last link of the band of a first box to the first link of the band of a second box.

En se reportant à la figure 1, une arme 1 (dont le canon est ici tronqué et n'est pas totalement visible) est montée pivotante sur des tourillons par rapport à un affût 3 formé d'une fourche, elle-même pivotante autour d'un axe 4 vertical par rapport à un socle 5. L'axe 2 des tourillons est représenté en pointillés sur la figure.Referring to FIG. 1, a weapon 1 (whose barrel is here truncated and not completely visible) is pivotally mounted on journals with respect to a
L'arme 1 ne fait pas l'objet de la présente invention et ne sera donc pas décrite en détails. Elle est ici équipée d'un viseur optronique 6.The
Cette arme 1 est une arme de moyen calibre (calibre inférieur ou égal à 50 mm). Elle est alimentée par des bandes de munitions. Une bande de munitions comprend des maillons qui maintiennent chacun une munition, les maillons sont liés les uns aux autres de façon articulée. Il est classique de rendre ainsi des munitions de petit ou moyen calibre solidaires de maillons pour faciliter l'alimentation de l'arme. Cette dernière comprend alors un moyen de démaillonage (non représenté) qui permet de désolidariser à l'entrée de l'arme les munitions d'avec les maillons.This
Les munitions sont disposées dans deux caisses 7a et 7b disposées côte à côte et solidaires d'une paroi latérale 8 de l'affût 3. Chaque caisse renferme une bande 11a ou 11b de munitions 9 (voir figure 3a).The ammunition is arranged in two
On voit ainsi sur la figure 1 des munitions 9 solidaires de maillons et qui sortent de la caisse 7b.Thus, FIG. 1 shows
La figure 3a montre une arme pour laquelle les deux caisses à munitions 7a et 7b sont garnies. La figure 6 est un agrandissement de la figure 3a montrant la partie supérieure des caisses 7a et 7b.Figure 3a shows a weapon for which the two
On voit sur cette figure, ainsi que sur la figure 7, que les munitions 9 sont disposées dans la caisse 7b de telle sorte que le premier maillon Ma de la bande 11b (ainsi que la première munition 9a) soient placés au niveau d'un premier bord latéral supérieur 12 de la caisse 7b. Bien entendu un même type de disposition de la bande de munition est prévu dans la caisse 7a.It can be seen in this figure, as well as in FIG. 7, that the
On voit sur la figure 7 que la bande 11b de munitions est lovée en zigzag jusqu'au fond de la caisse 7b, alors que le dernier maillon Mb (ainsi que la dernière munition 9b) de la bande 11b sont disposés au niveau de l'autre bord latéral supérieur 13.FIG. 7 shows that the
La bande 11b comporte ainsi une partie verticale Bv qui relie le fond de la caisse 7b et le rebord 13. Un crochet 24 permet le maintien de cette partie verticale Bv lors du remplissage de la caisse.The
Lors de l'alimentation de l'arme la bande 11b se décrochera naturellement du crochet 24 par simple pivotement.When feeding the weapon the
Il est ainsi possible de raccorder le dernier maillon de la bande 11a de la caisse 7a avec le premier maillon de la bande 11b de la caisse 7b (raccordement repéré en 14 sur la figure 6).It is thus possible to connect the last link of the
Ce raccordement est réalisé d'une façon classique à l'aide d'un outil approprié. Ainsi après mise en place sur l'arme des deux caisses 7a et 7b, les deux bandes 11a et 11b ne forment plus qu'une seule bande continue de munitions 9 réparties entre les deux caisses 7a et 7b.This connection is made in a conventional manner using a suitable tool. Thus, after placing the two
Le dispositif d'alimentation selon invention comprend également un couloir d'introduction 10 qui est monté pivotant par rapport à un axe sensiblement perpendiculaire à la paroi latérale, axe qui est confondu avec l'axe 2 des tourillons de l'arme 1.The feed device according to the invention also comprises an
Le couloir d'introduction 10 comporte ainsi une ouverture inférieure 10a (figure 2) qui est disposée au-dessus des caisses 7a et 7b et sensiblement au niveau d'un plan vertical séparant les deux caisses. Le couloir d'introduction 10 se trouve ainsi sensiblement à égale distance de chaque caisse à munition 7a, 7b et il est possible d'alimenter l'arme indifféremment à partir de l'une ou de l'autre des caisses 7a,7b. Du fait de ce positionnement du couloir 10 sensiblement au niveau du plan vertical séparant les caisses, les efforts exercés sur les bandes de munitions sont équivalents quelle que soit la caisse qui assure l'alimentation. Le passage d'une caisse à l'autre se fait donc sans heurts et sans qu'il soit nécessaire d'arrêter le tir.The
Par ailleurs la capacité de pivotement du couloir 10 par rapport à l'axe 2 facilite le guidage des munitions d'une caisse vers l'arme et la coaxialité du pivotement du couloir 10 par rapport au pivotement de l'arme sur ses tourillons permet d'assurer l'alimentation de l'arme quelle que soit l'orientation de celle ci en site sur ses tourillons.Moreover, the pivoting capacity of the
La figure 2 montre l'arme les caisses à munitions retirées. On voit que la paroi latérale 8 de l'affût 3 porte deux barres horizontales 15a et 15b destinées à recevoir les caisses 7a,7b.Figure 2 shows the weapon ammunition cases removed. We see that the
La barre supérieure 15a est fixe alors que la barre inférieure 15b peut se déplacer par rapport à la paroi 8 à l'aide d'un moyen de blocage 18 comprenant un excentrique actionné par une manivelle 19 (il y a en fait deux manivelles 19, une de chaque côté de la paroi 8).The
La figure 4 montre plus précisément le mode d'accrochage des caisses 7a, 7b sur les barres 15a, 15b ainsi que le moyen de blocage 18 assurant le verrouillage des caisses sur les barres.Figure 4 shows more precisely the attachment mode of the
On voit que chaque caisse 7a ou 7b comporte au niveau d'une face arrière 16a, 16b des crochets 17 et 17'. Chaque caisse comporte ainsi deux crochets supérieurs 17 coiffant la barre supérieure 15a et deux crochets inférieurs 17' qui sont ouverts vers le haut et sont donc positionnés en dessous de la barre inférieure 15b. Ces crochets 17' sont destinés à permettre le verrouillage des caisses. Les profils des crochets sont choisis de façon à entourer les barres sur environ 180°.We see that each
La manivelle 19 permet de commander manuellement un pivotement de la barre inférieure 15b.The
Comme cela est plus particulièrement visible aux figures 5a et 5b, la barre inférieure 15b est montée pivotante par rapport à un axe 21 solidaire de la paroi 8. La barre 15b est montée d'une façon excentrée par rapport à l'axe 21. On a représenté par la droite δ la ligne joignant dans le plan des figures l'axe 21 et l'axe de la barre cylindrique 15b. Le pivotement de la barre 15b par rapport à l'axe 21 est commandé par la manivelle 19.As is more particularly visible in Figures 5a and 5b, the
Le dispositif est représenté en position verrouillée sur la figure 5a. Un pivotement suivant la direction DV fait passer le dispositif à sa position déverrouillée représentée à la figure 5b. Le pivotement inverse (flèche V) le fait passer de la position déverrouillée de la figure 5b à celle de la figure 5a.The device is shown in the locked position in FIG. 5a. Pivoting in the DV direction will move the device to its unlocked position shown in Figure 5b. The reverse pivoting (arrow V) moves it from the unlocked position of Figure 5b to that of Figure 5a.
On voit que le pivotement de la barre dans le sens de verrouillage V permet d'abaisser la barre 15b, donc de l'appliquer contre les crochets 17' et d'assurer ainsi le verrouillage de la caisse 7a ou 7b par rapport à la paroi 8.It can be seen that the pivoting of the bar in the locking direction V makes it possible to lower the
Comme cela est visible sur la figure 5a, lors du mouvement de verrouillage la direction δ a dépassé la direction verticale A passant par l'axe 21 et forme un angle α avec cette dernière. Ainsi toute accélération verticale reçue par la caisse 7a ou 7b n'entraînera qu'une confirmation du verrouillage. Les caisses se trouvent ainsi solidement accrochées à la paroi 8.As can be seen in FIG. 5a, during the locking movement the direction δ has exceeded the vertical direction A passing through the
Selon une caractéristique essentielle de l'invention, chaque caisse 7a, 7b pourra par ailleurs coulisser par rapport à la paroi 8, sur les barres 15a, 15b, pour occuper indifféremment l'une ou l'autre position de chaque caisse.According to an essential characteristic of the invention, each
Il est alors possible après le retrait d'une caisse à munitions de faire passer la caisse restante à la position qui était occupée par la précédente.It is then possible after withdrawal of an ammunition box to move the remaining cash to the position that was occupied by the previous one.
Une telle disposition permet de réapprovisionner facilement l'arme en munitions sans désalimenter l'arme.Such an arrangement makes it easy to replenish the weapon in ammunition without de-energizing the weapon.
Ce mode de mise en oeuvre va être décrit en référence aux figures 3a, 3b et 3c.This embodiment will be described with reference to Figures 3a, 3b and 3c.
La figure 3a montre l'arme 1 dans une position initiale dans laquelle elle est équipée de deux caisses à munitions 7a et 7b chargées. On voit, comme cela a été décrit précédemment en référence à la figure 6, que la bande 11a de munitions de la caisse 7a est reliée à la bande 11b de munitions de la caisse 7b.Figure 3a shows the
Ainsi, lorsque la caisse 7a est vide, les munitions sont sans interruption prélevées dans la caisse 7b. Le couloir d'introduction étant positionné sensiblement au-dessus du plan de séparation des deux caisses 7a, 7b, le passage d'une caisse à l'autre se fait sans difficultés.Thus, when the
Il est donc possible de retirer la caisse 7a sans qu'il soit nécessaire de désolidariser la bande de munitions et l'arme. On libère cependant le moyen de blocage 18 pour permettre le démontage de la caisse vide.It is therefore possible to remove the
La figure 3b montre l'arme après retrait de la caisse 7a. Les munitions sont prélevées dans la caisse 7b. Le moyen de blocage étant libéré, il est alors possible de faire coulisser la caisse 7b sur la barre 15a suivant la direction D pour faire passer cette caisse 7b de sa position initiale à une position finale qui était celle occupée précédemment par la caisse 7a.Figure 3b shows the weapon after withdrawal of the
Ce déplacement là encore se fait sans qu'il soit nécessaire de désolidariser la bande de munitions et l'arme. La position finale est celle représentée à la figure 3c.This movement again is done without the need to separate the ammunition strip and the weapon. The final position is that shown in Figure 3c.
Il est alors possible de positionner une nouvelle caisse à munitions. Comme cela a déjà été précisé précédemment, le dernier maillon de la bande 11b de munitions est disposé au niveau d'un bord latéral supérieur 13 de la caisse 7b.It is then possible to position a new ammunition box. As already mentioned above, the last link of the
Après mise en place d'une nouvelle caisse de munitions il est donc possible de raccorder le dernier maillon de la bande 11b de la caisse 7b avec le premier maillon de la bande 11 de la nouvelle caisse 7 (non représentée).After setting up a new ammunition box it is possible to connect the last link of the
L'arme se retrouve alors dans une configuration identique à celle représentée à la figure 3a : deux caisses à munitions côte à côte renfermant chacune une bande de munitions. Les deux bandes étant solidaires et ne formant plus qu'une seule bande continue de munitions 9 réparties entre les deux caisses. Après ce rechargement de l'arme on verrouille les deux caisses à l'aide du moyen de blocage 18.The weapon is then found in a configuration identical to that shown in Figure 3a: two ammunition boxes side by side each containing a strip of ammunition. The two strips being integral and forming only one continuous strip of
L'invention est mise en oeuvre ici avec une arme de moyen calibre (calibre compris entre 20mm et 50 mm). Elle pourrait bien entendu être mise en oeuvre avec des armes de petitThe invention is implemented here with a medium-caliber weapon (caliber between 20 mm and 50 mm). It could of course be implemented with small weapons
