Abstract

The feeder consists of a magazine containing the bullets, situated parallel to the gun barrel (5), with the bullets (2) lying perpendicular to the barrel and beneath it. The bullets are transferred to the barrel by a mechanism which co-operates with the movement of the breech block (3) and comprises two levers (6,7) controlled by the breech block. During an initial phase, the movement of a lifter (8) perpendicular to the axis of the barrel, lifts the bullet at the end of the magazine and introduces it into a guide and, during a second phase, the lift and the guide are turned through 90 degrees to align the bullet with the barrel. In a third phase the lifter moves towards the barrel and the guide is freed. <IMAGE>

Description

La présente invention concerne un dispositif d'alimentation en munitions pour armes portatives automatiques, dans lequel l'alimentation est commandée par le retour de la culasse et le chargeur renfermant les munitions s'étend parallèlement à l'axe du canon de l'arme, les munitions étant disposées perpendiculairement à l'axe précité et sous celui-ci.The present invention relates to a device supply of ammunition for portable weapons automatic, in which the supply is controlled by the return of the cylinder head and the magazine containing the ammunition extends parallel to the axis of the barrel of the weapon, the ammunition being arranged perpendicular to the aforementioned axis and under it.

L'invention vise notamment un dispositif d'alimentation pour munitions dites "fragiles", telles que les munitions sans douille.The invention relates in particular to a supply device for so-called "fragile" ammunition, such as ammunition without socket.

Dans la plupart des armes portatives, la phase d'alimentation s'effectue lors du retour de la culasse. Cette dernière entraíne la munition de sa position de présentation (sensiblement parallèle à l'axe du canon) à la chambre du canon en poussant (chocs) sur le culot de la munition.In most portable weapons, the phase supply takes place when the cylinder head returns. This last drives the ammunition from its presentation position (substantially parallel to the axis of the barrel) to the chamber of the barrel by pushing (shocks) on the base of the ammunition.

Les munitions sans douille sont trop fragiles pour un tel principe d'alimentation. il faut donc envisager un dispositif d'alimentation approprié qui permette le transfert de la munition en minimisant les efforts qui lui sont appliqués.Ammunition without casing is too fragile for such a feeding principle. we must therefore consider a device appropriate supply that allows the transfer of ammunition by minimizing the forces applied to it.

En outre, ce dispositif d'alimentation doit permettre le transfert d'une munition à partir d'un chargeur longitudinal placé dans l'axe du canon, la munition étant présentée perpendiculairement à l'axe du canon.In addition, this feeding device must allow the transfer of ammunition from a longitudinal magazine placed in the axis of the barrel, the ammunition being presented perpendicular to the axis of the barrel.

Ce choix tire parti des avantages qu'offrent les munitions légères, car il permet d'intégrer des chargeurs à grande capacité (augmentation de la dotation en munitions du fantassin) sans altérer la compacité de l'arme.This choice takes advantage of the advantages offered by light ammunition because it allows to integrate chargers to large capacity (increased endowment of ammunition from infantryman) without altering the compactness of the weapon.

Le brevet FR2257887 dont l'exposé est pris à base du préambule de la revendication 1, décrit une arme à chambre rotative comportant un chargeur longitudinal et dans lequel la munition est introduite dans la chambre perpendiculairement à l'axe du canon. Ce dispositif met en oeuvre un poussoir d'introduction qui exerce un effort sur le culot de la munition. De plus il met en oeuvre une chambre tournante spécifique et ne peut être transposé à une arme dans laquelle la munition doit être introduite dans le canon.Patent FR2257887, the description of which is taken from the preamble of claim 1, describes a weapon with a rotating chamber comprising a longitudinal loader and in which the ammunition is introduced into the chamber perpendicular to the axis of the barrel. This device implements a pusher introduction which exerts an effort on the base of the ammunition. In addition it implements a rotating chamber specific and cannot be transposed to a weapon in which the ammunition must be introduced into the barrel.

La demande de brevet EP599683 publiée le 01/06/94 et bénéficiant de la date de priorité du 24/11/92 décrit aussi un système d'alimentation en munition pour une arme à chambre rotative. Ce dispositif ne permet pas non plus l'introduction d'une munition dans le canon d'une arme.Patent application EP599683 published on 06/01/94 and benefiting from the priority date of 24/11/92 described also an ammunition supply system for a handgun rotary chamber. This device also does not allow the introduction of ammunition into the barrel of a weapon.

L'invention a donc pour objet un dispositif d'alimentation en munitions pour arme portative automatique dans lequel l'alimentation est commandée par le retour de la culasse et le chargeur renfermant les munitions s'étend parallèlement à l'axe du canon de l'arme, les munitions étant disposées perpendiculairement à l'axe précité et sous celui-ci, dispositif comprenant un mécanisme coopérant avec le déplacement de la culasse pour :

  • pendant une première phase prélever une munition située à une extrémité du chargeur et la déplacer suivant une direction perpendiculaire à l'axe du canon pour l'introduire en même temps dans un guide,
  • pendant une deuxième phase faire tourner le guide de 90° pour disposer la munition dans l'axe du canon,
The invention therefore relates to a device for supplying ammunition for an automatic portable weapon in which the supply is controlled by the return of the breech and the magazine containing the ammunition extends parallel to the axis of the barrel of the weapon, the ammunition being arranged perpendicular to the aforementioned axis and under it, device comprising a mechanism cooperating with the movement of the breech for:
  • during a first phase take a piece of ammunition located at one end of the magazine and move it in a direction perpendicular to the axis of the barrel to introduce it at the same time into a guide,
  • during a second phase rotate the guide 90 ° to place the ammunition in the axis of the barrel,

ce dispositif est caractérisé en ce que le mécanisme comprend deux leviers commandés par le recul de la culasse et permettant de prélever et déplacer la munition avec un élévateur, l'élévateur permettant l'introduction de la munition dans le guide au cours de la première phase et étant conformé de façon à tourner avec le guide et la munition au cours de la deuxième phase, mécanisme permettant également pendant une troisième phase de déplacer l'élévateur vers le canon pour introduire la munition dans ce dernier et la libérer en même temps du guide.this device is characterized in that the mechanism includes two levers controlled by the recoil of the cylinder head and allowing to take and move the ammunition with a elevator, the elevator allowing the introduction of the ammunition in the guide during the first phase and being shaped so as to rotate with the guide and the ammunition at during the second phase, mechanism also allowing during a third phase to move the elevator towards the gun to introduce the ammunition into the latter and the release the guide at the same time.

Le dispositif d'alimentation permet ainsi lors du recul de la culasse de prélever les munitions du chargeur à partir de leur position perpendiculaire au canon, en les élevant vers le haut, ensuite de leur faire subir une rotation de 90° pour les présenter en regard du canon et enfin de les pousser successivement dans le canon.The feeding device thus allows when reversing of the breech to take the magazine ammunition from from their position perpendicular to the barrel, raising them up, then rotate them 90 ° to present them next to the barrel and finally to push them successively in the barrel.

Pendant toute l'opération, aucun choc n'est appliqué contre les munitions, de sorte que celles-ci ne risquent pas d'être abímées et le fonctionnement automatique de l'arme ne risque pas d'être perturbé.During the whole operation, no shock is applied against ammunition, so that it does not risk to be damaged and the automatic functioning of the weapon does not risk of being disturbed.

Selon une version avantageuse de l'invention, la culasse comporte sur l'un de ses côtés, une rainure dans laquelle est engagé un doigt solidaire d'une partie du mécanisme d'alimentation, cette rainure comportant une première partie s'étendant à partir de l'arrière de la culasse parallèlement à la direction de déplacement de la culasse, une deuxième partie formant une rampe montante et une troisième partie s'étendant parallèlement à la direction de déplacement de la culasse vers l'avant de celle-ci. According to an advantageous version of the invention, the cylinder head has on one of its sides a groove in which is engaged a finger secured to part of the mechanism feed, this groove comprising a first part extending from the rear of the cylinder head in parallel to the direction of movement of the bolt, a second part forming a rising ramp and a third part extending parallel to the direction of travel of the breech forward of it.

Cette rainure commande successivement l'élévation de l'élévateur perpendiculairement à la direction de déplacement de la culasse, la rotation de 90° de l'élévateur et du guide, puis le déplacement de l'élévateur en direction du canon.This groove controls successively the elevation of the elevator perpendicular to the direction of movement of the bolt, the rotation of 90 ° of the elevator and guide, then the displacement of the elevator towards the barrel.

Selon une particularité de l'invention, ledit doigt est porté par l'extrémité d'un premier levier relié de façon pivotante à une partie fixe de l'arme, l'autre extrémité de ce levier étant reliée de façon articulée à un second levier lui-même relié de façon pivotante d'une part à un organe monté en rotation dans une partie de l'arme, ledit organe comportant un guide pour positionner et transporter la munition et d'autre part, le levier étant d'autre part articulé à l'élévateur de la munition.According to a feature of the invention, said finger is carried by the end of a first lever pivotally connected to a fixed part of the weapon, the other end of this lever being connected so articulated with a second lever which is itself connected pivoting on the one hand to a member rotatably mounted in part of the weapon, said member comprising a guide to position and transport the ammunition and other on the other hand, the lever being articulated at the ammunition elevator.

De préférence, ledit organe est monté en rotation dans une empreinte formée dans le boítier de l'arme.Preferably, said member is mounted in rotation in an imprint formed in the housing of tear.

Selon une autre particularité de l'invention, ledit organe est une pièce plate de forme sensiblement circulaire, guidée en rotation dans une empreinte de forme complémentaire.According to another feature of the invention, said member is a flat piece of substantially shaped circular, guided in rotation in a footprint of complementary form.

De préférence, ledit organe comporte sur l'une de ses faces, une rainure dans laquelle est engagé l'élévateur.Preferably, said member comprises on one of its faces, a groove in which is engaged the elevator.

Cette rainure permet de guider le coulissement de l'élévateur.This groove guides the sliding of the elevator.

De préférence également ledit organe porte un guide présentant une goulotte pour la réception d'une munition et s'étendant parallèlement à la rainure dans laquelle est engagé l'élévateur.Preferably also said member carries a guide with a chute for receiving a ammunition and extending parallel to the groove in which is engaged the elevator.

Selon une autre particularité de l'invention, l'élévateur comprend une partie rectiligne engagée dans la rainure dudit organe pour pouvoir coulisser dans celle-ci, cette partie rectiligne comportant à son extrémité inférieure, un talon s'étendant vers la goulotte portée par ledit organe, ledit talon pouvant venir en prise sous une munition pour la déplacer dans la goulotte dudit organe lors de l'élévation dudit élévateur.According to another feature of the invention, the elevator comprises a rectilinear part engaged in the groove of said member to be able to slide in this one, this rectilinear part comprising at its lower end, a heel extending towards the chute carried by said member, said heel being capable of engage under ammunition to move it around the chute of said organ during the elevation of said elevator.

Le transporteur-guide 9 porte un guide 10 présentant une goulotte pour la réception d'une munition 2 et s'étendant parallèlement à la rainure 21 dans laquelle est engagé l'élévateur 8. Guide carrier 9 carries guide 10 having a chute for receiving an ammunition 2 and extending parallel to the groove 21 in which is engaged the elevator 8.

Comme indiqué, notamment sur les figures 8 et 10, l'élévateur 8 comprend une partie rectiligne 22 engagée dans la rainure 21 du transporteur-guide 9 pour pouvoir coulisser dans celle-ci. Cette partie rectiligne 22 comporte à son extrémité inférieure, un talon 23 s'étendant vers la goulotte du guide 10 porté par le transporteur-guide 9.As indicated, in particular in FIGS. 8 and 10, the elevator 8 comprises a rectilinear part 22 engaged in the groove 21 of the guide conveyor 9 for be able to slide in it. This straight part 22 has at its lower end a heel 23 extending towards the chute of the guide 10 carried by the guide carrier 9.

Comme montré par la figure 3, le talon 23 de l'élévateur peut venir en prise sous une munition 2 pour la déplacer dans la goulotte du guide 10 lors de l'élévation de l'élévateur 8.As shown in Figure 3, the heel 23 of the elevator can engage under ammunition 2 to move it in the chute of guide 10 when the elevation of the elevator 8.

Le premier levier 6 s'étend dans sa position initiale (voir figure 11) au-dessus du second levier 7. Ce levier 6 présente une forme générale arquée. Le second levier 7 a une forme sensiblement droite.The first lever 6 extends in its position initial (see figure 11) above the second lever 7. This lever 6 has a generally arcuate shape. The second lever 7 has a substantially straight shape.

Le premier levier 6 est relié au second levier 7 et ce dernier est relié à l'élévateur 8 par des pivots 15, 19 engagés dans des rainures 24, 25 permettant une certaine translation dans la direction d'allongement du second levier 7.The first lever 6 is connected to the second lever 7 and the latter is connected to the elevator 8 by pivots 15, 19 engaged in grooves 24, 25 allowing a some translation in the direction of elongation of the second lever 7.

Par ailleurs, une butée est prévue pour bloquer en rotation le transporteur-guide 9 portant le guide 10 en forme de goulotte pendant la phase initiale d'élévation de l'élévateur 8 et une seconde butée est prévue pour bloquer à nouveau en rotation le transporteur-guide précité, après rotation de celui-ci de 90° à partir de la position initiale (représentée sur la figure 11), pendant la phase de déplacement de l'élévateur 8 vers le canon 5.In addition, a stop is provided to block in rotation the guide conveyor 9 carrying the guide 10 chute-shaped during the initial phase elevation of elevator 8 and a second stop is designed to block the rotation again aforementioned guide carrier, after rotation thereof 90 ° from the initial position (shown on Figure 11), during the displacement phase of the elevator 8 towards the barrel 5.

Les butées précitées sont formées dans l'empreinte 20 ménagée dans le boítier 14 de l'arme.The abovementioned stops are formed in the imprint 20 formed in the housing 14 of the weapon.

Comme indiqué sur la figure 15, l'empreinte 20 comporte une partie sensiblement circulaire mais présentant deux rayons R1, R2 légèrement différents, dans laquelle vient se loger le transporteur-guide 9 rotatif. Cette partie sensiblement circulaire débouche vers le bas dans une rainure 26 dans laquelle est engagé l'élévateur 8 lors de la phase d'élévation verticale. Cette partie sensiblement circulaire débouche d'autre part dans une seconde rainure 27 située à 90° de la précédente dans laquelle s'engage l'élévateur 8 pendant sa phase de déplacement vers le canon 5.As indicated in FIG. 15, the cavity 20 comprises a substantially circular part but having two slightly different radii R 1 , R 2 , in which the rotary guide-carrier 9 is housed. This substantially circular part opens downward into a groove 26 in which the elevator 8 is engaged during the vertical elevation phase. This substantially circular part also opens into a second groove 27 located 90 ° from the previous one in which the elevator 8 engages during its phase of movement towards the barrel 5.

L'élévateur 8 est dégagé de ces rainures 26, 27 entre les deux phases ci-dessus pour permettre la rotation de 90° du transporteur-guide 9.The elevator 8 is released from these grooves 26, 27 between the two phases above to allow the 90 ° rotation of the guide conveyor 9.

On va maintenant décrire en référence aux figures 11 à 15, le fonctionnement du dispositif d'alimentation détaillé ci-dessus.We will now describe with reference to Figures 11 to 15, the operation of the device power supply detailed above.

A l'ouverture, la culasse 3 recule sous l'effet du coup de feu, et entraíne en rotation, par sa rampe 11 en forme de "S" inversé, les leviers 6, 7 de commande du mécanisme d'alimentation.At the opening, the cylinder head 3 moves back under the effect of the shot, and drives in rotation, by its ramp 11 in the form of an inverted "S", the levers 6, 7 for controlling the feeding mechanism.

L'alimentation s'effectue en trois phases successives:
   Phase 1 (voir figure 12): Translation verticale de la munition 2 sur une distance "a"The feeding takes place in three successive phases:
Phase 1 (see Figure 12): Vertical translation of ammunition 2 over a distance "a"

Poussée par l'élévateur 8, la munition 2 est extraite du chargeur et est engagée dans la goulotte 10 du transporteur-guide 9. Le transporteur-guide 9 est immobilisé en rotation, bloqué par l'élévateur 8 en butée dans l'empreinte 26 du boítier 14.
   Phase 2 (voir figure 13): Rotation de 90° de la munition 2Pushed by the elevator 8, the ammunition 2 is extracted from the magazine and is engaged in the chute 10 of the guide transporter 9. The guide transporter 9 is immobilized in rotation, blocked by the elevator 8 abutting in the cavity 26 housing 14.
Phase 2 (see figure 13): Rotation of ammunition 2 by 90 °

L'élévateur 8 n'étant plus en butée dans l'empreinte 26 du boítier 14, l'ensemble transporteur-guide 9/élévateur 8/munition 2 est libéré et tourne, permettant de positionner la munition 2 dans l'axe du canon 5.The elevator 8 is no longer in abutment in the imprint 26 of the housing 14, the carrier-guide assembly 9 / elevator 8 / ammunition 2 is released and turns, to position the ammunition 2 in the axis of the canon 5.

La munition 2 est maintenue fixe entre la goulotte 10 du transporteur-guide 9 et l'élévateur 8.
   Phase 3 (voir figure 14): Translation horizontale de la munition 2 sur un distance "b"The ammunition 2 is kept fixed between the chute 10 of the guide conveyor 9 and the elevator 8.
Phase 3 (see Figure 14): Horizontal translation of ammunition 2 over a distance "b"

Poussée par l'élévateur 8, la munition 2 est libérée de la goulotte 10 du transporteur-guide 9 et est introduite dans le canon 5. Le transporteur-guide 10 est à nouveau immobilisé en rotation, bloqué par l'élévateur 8 en butée dans l'empreinte 27 du boítier 14.Pushed by the elevator 8, the ammunition 2 is released from the chute 10 of the guide conveyor 9 and is introduced into the barrel 5. The guide conveyor 10 is again immobilized in rotation, blocked by the elevator 8 in abutment in the imprint 27 of the housing 14.

A la fermeture, la culasse 3, ramenée en position avant, commande le mouvement inverse des éléments du mécanisme d'alimentation qui retrouvent leur position initiale.When closing, the cylinder head 3, brought back in forward position, controls the reverse movement of elements of the feeding mechanism which regain their initial position.

Un dispositif de retenue de la colonne de munitions du chargeur, effaçable au retour du mécanisme d'alimentation, évite l'interférence mécanique (choc) entre l'élévateur et les munitions suivantes du chargeur.A column retaining device magazine ammunition, erasable on return of the mechanism power supply, avoids mechanical interference (shock) between the elevator and the following munitions of the charger.

Bien entendu l'invention n'est pas limitée à l'exemple que l'on vient de décrire et on peut apporter à celui-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the example that we just described and we can bring to this one many modifications without leaving the part of the invention.
