Description

L'invention a pour objet un fusil automatique, à ca­non basculant ou non, fonctionnant par emprunt de gaz.The subject of the invention is an automatic rifle, with a tilting barrel or not, operating by borrowing gas.

La réalisation de fusils fonctionnant par emprunt de gaz est connue en soi et a été développée par de nombreux fabri­cants.The production of gas-operated rifles is known per se and has been developed by many manufacturers.

Le but recherché selon l'invention résidait dans la conception d'un nouveau fusil fonctionnant par emprunt de gaz en utilisant l'énergie de ceux-ci pour atuoriser l'avancée du canon et simultanément l'extraction de la cartouche tirée et l'intro­duction d'une nouvelle cartouche à partir du tube magasin.The aim sought after according to the invention resided in the design of a new rifle operating by borrowing gas by using the energy of these to atuorise the advance of the barrel and simultaneously the extraction of the fired cartridge and the introduction a new cartridge from the magazine tube.

Avec cette nouvelle conception de fusil un autre but était d'obtenir une réduction de sa longueur d'une manière ap­préciable.With this new rifle design another goal was to achieve a substantial reduction in its length.

Ces buts sont atteints et le fusil proposé selon l'invention est d'une grande fiabilité et rapidité de fonction­nement, chargement et déchargement. En outre, l'arme est plus courte d'environ 7 à 10 centimètres eu égard aux fusils similai­res fonctionnant par emprunt de gaz. Egalement, le fusil obtenu selon l'invention présente une esthétique nouvelle ce qui lui confère un attrait particulier.These aims are achieved and the rifle proposed according to the invention is of great reliability and speed of operation, loading and unloading. In addition, the weapon is shorter by approximately 7 to 10 centimeters compared to similar rifles operating by borrowing gas. Also, the rifle obtained according to the invention has a new aesthetic which gives it a particular appeal.

Selon une première caractéristique de l'invention, le canon est monté avec une capacité de déplacement vers l'avant par rapport au tube magasin ; la partie avant dudit canon rece­vant dans sa partie inférieure un fourreau constituant intérieu­rement une chambre d'expansion des gaz en communication avec le canon ; ledit tube magasin présentant un prolongement s'enga­geant partiellement dans le fourreau sans obturer l'ouverture de passage des gaz ; un piston coulissant dans ledit fourreau sous la poussée des gaz et agissant à l'encontre du ressort de récu­pération du canon par l'intermédiaire d'un moyen en vue du dé­verrouillage du canon et son déplacement par rapport au tube magasin ; ledit moyen étant assujetti à un couple de tringles coulissant le long du tube magasin et de la bascule pour autori­ser l'armement du chien de percussion et la remontée du moyen élévateur de cartouches dans le tube canon.According to a first characteristic of the invention, the barrel is mounted with a capacity of displacement forwards with respect to the magazine tube; the front part of said barrel receiving in its lower part a sheath internally constituting a gas expansion chamber in communication with the barrel; said store tube having an extension partially engaging in the sheath without closing the gas passage opening; a piston sliding in said sheath under the thrust of the gases and acting against the recovery spring of the barrel by means of a means for unlocking the barrel and its displacement relative to the magazine tube; said means being subject to a pair of rods sliding along the magazine tube and the rocker to authorize the arming of the hammer hammer and the ascent of the cartridge lifting means in the barrel tube.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These characteristics and others will emerge clearly from the following description.

On fait référence à un canon basculant selon une pre­mière réalisation.Reference is made to a tilting barrel according to a first embodiment.

Le fusil comprend une carcasse profilée (1) formant bascule à son extrémité avant et agencée à l'arrière pour la fixation de manière classique de la crosse (2). On a illustré schématiquement la clé (3) d'ouverture du canon, la queue de détente (4), l'extracteur (5), le chien (6), les autres moyens connus en soi tels que la détente, la gâchette, la culasse et autres moyens principaux utilisés généralement, n'étant pas il­ lustrés pour la clarté des dessins.The rifle comprises a profiled carcass (1) forming a rocker at its front end and arranged at the rear for fixing in a conventional manner the stock (2). The key (3) for opening the barrel, the trigger tail (4), the extractor (5), the hammer (6), the other means known per se, such as the trigger, the trigger, have been illustrated diagrammatically. the cylinder head and other main means generally used, not being glossy for clarity of designs.

En se référant aux dessins, le canon (7) est monté avec une capacité de coulissement par des rainures appropriées (8) le long du tube magasin (9) monté à pivotement sur le tou­rillon (10) en bout de la bascule. Le tube magasin est agencé pour recevoir intérieurement plusieurs cartouches (11) mainte­nues en position par un cran d'arrêt approprié (12) à l'encontre d'un ressort (13) de détente disposé au fond dudit magasin.Referring to the drawings, the barrel (7) is mounted with a sliding capacity by appropriate grooves (8) along the magazine tube (9) pivotally mounted on the pin (10) at the end of the rocker. The magazine tube is arranged to internally receive several cartridges (11) held in position by a suitable stop notch (12) against a detent spring (13) disposed at the bottom of said magazine.

A l'avant du canon est fixé dans sa partie inférieure un fourreau (14) présentant une portée (15) de raccordement et de communication avec l'intérieur du canon pour le passage des gaz. En outre, le tube magasin en avant se prolonge directement ou indirectement par un moyen tubulaire rapporté pour s'engager partiellement dans l'alésage intérieur dudit fourreau jusqu'à venir sensiblement tangenter, sans toutefois l'obturer, l'ouver­ture (16) de passage des gaz du canon à la chambre d'expansion des gaz dudit fourreau en position initiale. A l'intérieur de ce fourreau coulisse un piston (17) situé à proximité de l'ouvertu­re de passage des gaz et au-delà de celle-ci et se déplaçant pour venir en regard de la face de fond (14-1) avant du four­reau. La tige (18) du piston traverse la partie avant de prolon­gement du tube magasin et est associée à son extrémité selon une première réalisation à un moyen réalisé sous la forme d'un élé­ment rapporté (19) constituant un anneau ou collier susceptible de coulisser en étant guidé le long du tube magasin. Autour de la tige du piston est disposé le ressort de récupération (20) du canon qui est maintenu en position par l'extrémité (9-1) du tube magasin et une face d'appui (19-1) intérieure de l'anneau (19).At the front of the barrel is fixed in its lower part a sleeve (14) having a bearing surface (15) for connection and communication with the interior of the barrel for the passage of gases. In addition, the front store tube is extended directly or indirectly by an insert tubular means for partially engaging in the internal bore of said sheath until it comes to substantially tangent, without however closing it, the opening (16) of passage of gases from the barrel to the gas expansion chamber of said sheath in the initial position. Inside this sleeve slides a piston (17) located near the gas passage opening and beyond it and moving to come opposite the bottom face (14-1) before scabbard. The rod (18) of the piston passes through the front part of the extension of the magazine tube and is associated at its end according to a first embodiment with a means produced in the form of an attached element (19) constituting a ring or collar capable of sliding in being guided along the magazine tube. Around the piston rod is arranged the recovery spring (20) of the barrel which is held in position by the end (9-1) of the magazine tube and an internal bearing face (19-1) of the ring. (19).

L'introduction des gaz dans la chambre d'expansion selon la flêche F agit en poussée sur le piston provoquant ainsi par le déplacement de l'anneau sur le tube magasin, le sollici­tation en compression dudit ressort (20). Pour permettre le dé­placement de l'anneau (19), il est prévu sur les faces en regard du tube magasin, des rainures (21) de guidage d'une certaine longueur agissant comme limiteur de déplacement. On a illustré aux figures 9, 10 et 11 le déplacement du canon après le tir. En position de déplacement maximum du canon, la cartouche tirée est automatiquement éjectée. Il est prévu en outre une ouverture (14-2) arrière pour l'échappement des gaz restant lors du retour du piston.The introduction of gases into the expansion chamber according to arrow F acts on the piston pushing thus causing by the displacement of the ring on the magazine tube, the compression stress of said spring (20). To allow the movement of the ring (19), there are provided on the opposite faces of the magazine tube, grooves (21) of guide of a certain length acting as a displacement limiter. We illustrated Figures 9, 10 and 11 the displacement of the barrel after firing. In the maximum displacement position of the barrel, the fired cartridge is automatically ejected. A rear opening (14-2) is also provided for the escape of the gases remaining during the return of the piston.

Par ailleurs, l'anneau (19) et le tube magasin sont agencés avec une découpe formant encoche (19-2) profilée formant ensemble le siège d'un verrou (22) basculant dont l'axe (23) est solidaire du canon. Ainsi qu'il apparaît aux dessins, en posi­tion repos, le verrou (22) est bloqué en position et ne se libè­re que lors du déplacement vers l'avant de l'anneau après le tir se dégageant également de la partie formant encoche du tube ma­gasin.Furthermore, the ring (19) and the magazine tube are arranged with a cutout forming a notch (19-2) profiled together forming the seat of a tilting bolt (22) whose axis (23) is integral with the barrel. As it appears in the drawings, in the rest position, the latch (22) is locked in position and is released only when the ring moves forwards after the shot also emerges from the notch portion of the tube store.

Selon une autre disposition caractéristique de l'in­vention, il est prévu une paire de tringles (24) (25), l'une étant fixée à l'anneau (19) coulissant le long du tube magasin et l'autre coulissant le long de la bascule pour autoriser l'ar­mement du chien (6) de percussion après le tir du premier coup et permettre la remontée du moyen élévateur (26) de cartouche dans le tube canon. Ces dispositions sont en particulier illus­trées aux figures 4 à 8 des dessins. Plus précisément, la trin­gle (24) associée à l'anneau (19) présente en bout d'extrémité une encoche (24-1) susceptible de s'ajuster dans une forme com­plémentaire (25-1) établie à l'extrémité avant et opposée de la seconde tringle (25) lors de la fermeture du canon, les deux tringles étant ainsi étroitement associées dans leur mouvement lors du fonctionnement de tir du fusil.According to another characteristic arrangement of the invention, there is provided a pair of rods (24) (25), one being fixed to the ring (19) sliding along the magazine tube and the other sliding along the rocker to authorize the hammer of the hammer (6) percussion after the firing of the first shot and allow the ascent of the lifting means (26) of cartridge in the barrel tube. These provisions are in particular illustrated in Figures 4 to 8 of the drawings. More specifically, the rod (24) associated with the ring (19) has at the end of a notch (24-1) capable of fitting into a complementary shape (25-1) established at the front end and opposite the second rod (25) when closing the barrel, the two rods being thus closely associated in their movement during the firing operation of the rifle.

La tringle (25) est agencée avec sur sa longueur une réduction de section définissant une face de butée (25-2) contre laquelle viendra en appui un doigt (27) disposé en débordement sur le chien de percussion (6) provoquant en bout de course, à l'encontre d'un ressort de rappel (28) son basculement et arme­ment. Pendant la période d'avancée de la tringle (25) (figure 5), le chien est maintenu en position par la gachette assujettie à la détente non illustrées aux dessins. Tant que la tringle (25) n'est pas revenue en arrière, le chien ne peut être percu­té. La tringle (25) arme le chien de percussion pour les coups supplémentairés mais lors du premier tir, le chien est armé par le basculement de l'élévateur, ainsi qu'il sera précisé par la suite.The rod (25) is arranged with a reduction in section along its length defining a stop face (25-2) against which will come to bear a finger (27) disposed in overflow on the percussion hammer (6) causing at the end of stroke, against a return spring (28) tilting and arming. During the period of advance of the rod (25) (Figure 5), the dog is held in position by the trigger subject to the trigger not shown in the drawings. As long as the rod (25) has not gone back, the dog cannot be struck. The rod (25) arms the hammer percussion for additional shots but during the first shot, the dog is armed by the tilting of the elevator, as will be specified later.

La tringle (25) comprend, en outre, dans sa partie arrière, un talon supérieur (25-3) formant éjecteur. Lorsque la tringle (25) se situe en bout de course avant, elle provoque l'éjection de la cartouche tirée retenue par l'extracteur.The rod (25) further comprises, in its rear part, an upper heel (25-3) forming an ejector. When the rod (25) is at the front end of travel, it causes the ejection of the drawn cartridge retained by the extractor.

Selon une autre disposition, la tringle (25) présente dans sa partie inférieure arrière un ergot (29) susceptible de coopérer avec l'élévateur (26) comme illustré aux figures 6 à 8 montrant les différentes phases lors du déplacement de la trin­gle (25).According to another arrangement, the rod (25) has in its rear lower part a lug (29) capable of cooperating with the elevator (26) as illustrated in FIGS. 6 to 8 showing the different phases during the displacement of the rod (25 ).

L'élévateur (26) comprend un levier de chargement (26-­1) articulé dans sa partie arrière sur un axe (26-2) et se pro­longeant avec une partie externe formant came (26-3) également articulée sur ledit axe à l'encontre d'un moyen élastique de rappel (30) dont une extrémité (30-1) est fixée au levier de chargement. L'élévateur est sollicité en mouvement par le dépla­cement de la tringle (25) dans les conditions suivantes.The elevator (26) comprises a loading lever (26-1) articulated in its rear part on an axis (26-2) and extending with an external part forming a cam (26-3) also articulated on said axis to the 'against an elastic return means (30), one end (30-1) is fixed to the loading lever. The elevator is stressed in movement by the displacement of the rod (25) under the following conditions.

En position initiale, la tringle (25) se trouve en retrait de l'élévateur. Suite au mouvement d'entraînement donné par le levier (24) lors du déplacement du piston (17) dans la chambre d'expansion des gaz, la tringle (25) se déplace vers l'avant de sorte que l'ergot (29) vienne en appui sur la came (26-3) qui s'efface par basculement à l'encontre du moyen élas­tique de rappel (30) précité qui est comprimé. L'ergot (29) se situant devant la came (26-3), celle-ci revient en position par l'effet de détente du ressort. Lors du retour de la tringle (25) dans sa position initiale, l'ergot (29) va venir en butée une nouvelle fois sur la came (26-3) mais de l'autre côté de celle-­ci. Ladite came ne pouvant basculer en sens inverse, l'action de l'ergot (29) va provoquer le basculement de l'élévateur (26) par rapport à son axe d'articulation et autoriser ainsi le charge­ ment d'une nouvelle cartouche dans le canon du fusil, lors du retour en position initiale de celui-ci, figures 13 et 14.In the initial position, the rod (25) is set back from the elevator. Following the driving movement given by the lever (24) during the displacement of the piston (17) in the gas expansion chamber, the rod (25) moves forward so that the lug (29) comes to bear on the cam (26-3) which disappears by tilting against the aforementioned elastic return means (30) which is compressed. The lug (29) being located in front of the cam (26-3), the latter returns to position by the rebound effect of the spring. When the rod (25) returns to its initial position, the lug (29) will again come into abutment on the cam (26-3) but on the other side of the latter. Said cam can not tilt in the opposite direction, the action of the lug (29) will cause the tilting of the elevator (26) relative to its axis of articulation and thus authorize the load ment of a new cartridge in the rifle barrel, when returning to its initial position, Figures 13 and 14.

En se référant aux figures 2, 15 et 16, le moyen élé­vateur assure une seconde fonction dans le cas du canon bascu­lant.Referring to Figures 2, 15 and 16, the lifting means performs a second function in the case of the tilting barrel.

L'extrémité avant (26-4) du levier de chargement (26) prend sensiblement appui sur la partie métallique (35), en soi connue, associée au devant-bois du canon (36). Lors de l'ouver­ture du fusil le levier de chargement est ainsi basculé par rap­port à son axe d'articulation (26-2) et subit un mouvement de pivotement. L'extrémité (6-1) du chien (6) qui est en contact avec ledit levier de chargement (26) est ainsi basculé par rap­port à son axe d'articulation, à l'encontre de son ressort de rappel et ainsi armé.The front end (26-4) of the loading lever (26) is substantially supported on the metal part (35), known per se, associated with the front of the barrel (36). When the rifle opens, the loading lever is thus tilted relative to its articulation axis (26-2) and undergoes a pivoting movement. The end (6-1) of the dog (6) which is in contact with said loading lever (26) is thus tilted relative to its axis of articulation, against its return spring and thus armed.

L'armement du chien pour les autres tirs s'effectue de la manière qui est exposée précédemment.The arming of the dog for other shots is carried out in the manner described above.

Une autre réalisation du mécanisme de verrouillage du canon en vue de son chargement est illustrée aux figures 17, 18, 19, 20, 21, 22, le piston (32) assurant la même fonction que le piston (17) dans la mise en oeuvre précédente, comprend directe­ment ou d'une manière rapportée un corps intermédiaire tubulaire (32-1) de petit diamètre introduit dans le prolongement avant du tube magasin (9), une extrémité avant (32-2) coopérant à l'inté­rieur du fourreau sous la poussée des gaz, et une partie arrière établie sous la forme d'un manchon cylindrique (32-3) s'ajustant à coulissement dans le tube magasin. A l'intérieur du piston est monté un axe (33) à position fixe, solidarisé par sa partie avant (33-1) par vissage et de manière démontable à la face avant extérieure du fourreau. L'extrémité arrière dudit axe pré­sente une portée (33-2) de plus grande section s'ajustant à l'intérieur de la partie manchon (32-3) du piston. Le ressort de récupération (20) du canon est monté autour de corps intermé­diaire du piston et vient en appui contre la face extérieure du regard du manchon, et le fond (9-1) du tube magasin.Another embodiment of the barrel locking mechanism for loading is illustrated in Figures 17, 18, 19, 20, 21, 22, the piston (32) performing the same function as the piston (17) in the implementation previous, includes directly or in a reported manner a tubular intermediate body (32-1) of small diameter inserted in the front extension of the magazine tube (9), a front end (32-2) cooperating inside the sheath under the thrust of the gases, and a rear part established in the form of a cylindrical sleeve (32-3) slidingly adjusting in the magazine tube. Inside the piston is mounted a pin (33) in a fixed position, secured by its front part (33-1) by screwing and detachably to the outer front face of the sheath. The rear end of said axis has a bearing surface (33-2) of larger section fitting inside the sleeve part (32-3) of the piston. The recovery spring (20) of the barrel is mounted around the intermediate body of the piston and bears against the outside face of the manhole cover, and the bottom (9-1) of the magazine tube.

Par ailleurs, il est prévu un moyen de verrouillage du canon. Ce moyen est constitué par un doigt (34) disposé sur la portée arrière (33-2) dudit axe radialement vers l'extérieur s'ajustant et coopérant dans une fente (32-4) établie sur le manchon du piston. Cette fente est diposée angulairement par rapport à l'axe longitudinal du piston. Il est en outre réalisé sur le tube magasin en regard de la fente précitée, une rainure (21) de guidage d'une certaine longueur agissant comme limiteur de déplacement du doigt (34). Cette rainure présente une échan­crure (21-1) en forme de baïonnette servant de moyen de logement et de verrouillage du doigt (34).Furthermore, a locking means is provided. from the barrel. This means consists of a finger (34) disposed on the rear bearing surface (33-2) of said axis radially outwardly adjusting and cooperating in a slot (32-4) established on the sleeve of the piston. This slot is disposed angularly relative to the longitudinal axis of the piston. It is also produced on the magazine tube opposite the aforementioned slot, a groove (21) for guiding a certain length acting as a movement limitation of the finger (34). This groove has a notch (21-1) in the form of a bayonet serving as a means of housing and locking the finger (34).

Le fonctionnement est le suivant. Lors du tir sous l'action de poussée de gaz, le piston (32) est soumis à un dé­placement vers l'avant. Par l'effet de la fente (32-4) jouant un rôle de came, le doigt (34) est basculé angulairement de quel­ques degrés permettant ainsi son échappement de l'échancrure ou encoche (21-1) établie sur le tube magasin. Le doigt (34) peut alors coulisser d'une manière contrôlée et limitée en butée par le fond de la rainure autorisant ainsi le déplacement de l'en­semble canon-fourreau. Sous l'effet inverse de détente du res­sort de récupération du canon, et du retour du piston, le doigt (34) revient progressivement en position inverse ; en bout de la rainure (21), le doigt se déplace angulairement sous l'action finale de détente du ressort et se verrouille dans l'échancrure (21-1) bloquant en position le canon.The operation is as follows. When fired under the thrust of gas action, the piston (32) is subjected to a forward movement. By the effect of the slot (32-4) acting as a cam, the finger (34) is tilted angularly by a few degrees thereby allowing it to escape from the notch or notch (21-1) established on the magazine tube. The finger (34) can then slide in a controlled and limited manner in abutment by the bottom of the groove thus authorizing the displacement of the barrel-barrel assembly. Under the opposite effect of expansion of the recovery spring of the barrel, and the return of the piston, the finger (34) gradually returns to the reverse position; at the end of the groove (21), the finger moves angularly under the final action of relaxation of the spring and locks in the notch (21-1) blocking the barrel in position.

Cette seconde réalisation du mécanisme de verrouilla­ge du canon est facile à réaliser au niveau de la fabrication des pièces et permet le changement aisé du canon puisqu'il suf­fit de desserrer la vis de fixation de l'axe (33).This second embodiment of the barrel locking mechanism is easy to produce in the manufacture of parts and allows the barrel to be changed easily since it suffices to loosen the fixing screw of the axle (33).

Il y a lieu en outre de penser que le manchon (32) est associé à la tringle (25) décrite précédemment. La liaison s'effectue par vis ou autrement.There is also reason to think that the sleeve (32) is associated with the rod (25) described above. The connection is made by screw or otherwise.

Les dispositions de l'invention sont applicables éga­lement au fusil automatique à canon non basculant. On a illustré à la figure 23, la variante de réalisation qui comprend outre les différents mécanismes décrits précédemment, une pièce sup­ plémentaire (31) mobile et déplaçable par rapport au tube maga­sin. Cette pièce assure la fonction d'un poussoir avec deux flasques latéraux (31-1)(31-2) munis d'une ouverture pour le coulissement sur le tube magasin. Le flasque latéral (31-1) est disposé par rapport à l'anneau (19) en lui servant de moyen de butée arrière. Le flasque latéral (31-2) est destiné à venir en appui contre la face en regard du fourreau (14). Le poussoir est fixé à la partie devant bois.The provisions of the invention are also applicable to the automatic rifle with a non-tilting barrel. Illustrated in Figure 23, the alternative embodiment which comprises in addition to the various mechanisms described above, a sup movable (31) movable and movable relative to the magazine tube. This part performs the function of a plunger with two lateral flanges (31-1) (31-2) provided with an opening for sliding on the magazine tube. The lateral flange (31-1) is disposed relative to the ring (19) by serving as a rear stop means. The lateral flange (31-2) is intended to bear against the opposite face of the sheath (14). The pusher is attached to the front part of the wood.

Pour assurer l'armement manuel, le tireur agit direc­tement sur l'élément poussoir (31) qui déplace ainsi l'anneau (19) vers l'avant assurant ainsi le déverrouillage du canon par échappement du verrou. Par son flasque avant (31-2) le poussoir vient en butée contre le fourreau (14) solidaire du canon per­mettant le déplacement de l'ensemble et l'introduction d'une cartouche nouvelle dans le canon. Le remplissage du tube magasin s'effectue par le dessous du fusil de manière classique.To ensure manual arming, the shooter acts directly on the pusher element (31) which thus displaces the ring (19) forwards, thus ensuring the unlocking of the barrel by escaping the lock. By its front flange (31-2) the pusher abuts against the sheath (14) integral with the barrel allowing the movement of the assembly and the introduction of a new cartridge into the barrel. The filling of the magazine tube is carried out from below the rifle in a conventional manner.

En variante de la figure 23, le mécanisme de ver­rouillage du canon peut être semblable à celui illustré aux fi­gures 17 à 22 de la Demande, tel qu'illustré figure 24.As a variant of FIG. 23, the locking mechanism of the barrel can be similar to that illustrated in FIGS. 17 to 22 of the Application, as illustrated in FIG. 24.

Les avantages ressortent bien de l'invention. On sou­ligne la fiabilité de fonctionnement du fusil, son faible encom­brement.The advantages emerge clearly from the invention. The reliability of the rifle's operation and its small size are emphasized.
