Description

Verrou de chargeur Magazine lock
Objet de l'invention Object of the invention
[0001] La présente invention se rapporte à dispositif de verrouillage et de libération d'un chargeur d'une arme à feu, de préférence de type pistolet. The present invention relates to a device for locking and releasing a magazine of a firearm, preferably of the pistol type.
Etat de la technique State of the art
[0002] Les armes à feu automatiques et semi-automatiques alimentées par chargeur comprennent des moyens verrouillant le chargeur lors de l'utilisation de l'arme. Dans le cas de carabine ou de fusil d'assaut, le chargeur est généralement disposé dans un puit de chargeur disposé en avant du pontet dans le cas de carabines classiques de type FN FNC ou AK47 ou en arrière dans le cas d'arme de type bullpup. Dans ce cas, la commande de verrou de chargeur est généralement disposé dans la carcasse et nécessite de déplacer les mains pour changer de chargeur. [0002] Magazine-fed automatic and semi-automatic firearms include means for locking the magazine during use of the weapon. In the case of a rifle or an assault rifle, the magazine is generally arranged in a magazine well arranged in front of the trigger guard in the case of conventional rifles of the FN FNC or AK47 type or behind in the case of a weapon of the type bullpup. In this case, the magazine lock control is generally arranged in the carcass and requires moving the hands to change the magazine.
[0003] Dans le cas des armes de poings semi-automatiques de type pistolet, le chargeur est généralement disposé dans la poignée elle-même et elle est verrouillée au moyen d'un bouton poussoir qui peut être déplacé en translation perpendiculaire à la poignée et à l'axe du canon pour déverrouiller le chargeur. Ce verrou de chargeur est disposé à proximité de la position normale du pouce lors du tir, de façon à permettre une éjection aisée du chargeur vide en fin de séquence de tir, et un rechargement sans modifier la position de tir de la main en prise sur la poignée. [0003] In the case of pistol-type semi-automatic handguns, the magazine is generally arranged in the handle itself and it is locked by means of a push button which can be moved in translation perpendicular to the handle and to the barrel axis to unlock the magazine. This magazine lock is placed close to the normal position of the thumb during firing, so as to allow easy ejection of the empty magazine at the end of the firing sequence, and reloading without modifying the firing position of the hand in grip on the the handle.
[0004] La rapidité de changement de chargeur est encore améliorée par la présence sur la planche de chargeur d'une protubérance actionnant un arrêtoir de culasse (ou de glissière) maintenant la glissière et/ou la culasse en arrière après le tir de la dernière cartouche. L'arrêt de la culasse en arrière a pour effet d'indiquer au tireur qu'il n'a plus de cartouche, et simplifie le rechargement, la culasse étant en position pour recharger une nouvelle cartouche d'un nouveau chargeur. [0004] The speed of magazine change is further improved by the presence on the magazine board of a protuberance actuating a breech (or slide) retainer holding the slide and/or the breech back after firing the last cartridge. Stopping the bolt backwards has the effect of indicating to the shooter that he no longer has a cartridge, and simplifies reloading, the bolt being in position to reload a new cartridge from a new magazine.
[0005] Néanmoins, ce type de verrou de chargeur présente au moins deux inconvénients. D'une part, la position et le type de mouvement par simple pression du pouce peut induire une libération du chargeur intempestive en raison d'un faux mouvement du tireur, et d'autre part, la position du pouce doit être adaptée à la préhension droitière ou gauchère du tireur. [0005] Nevertheless, this type of charger lock has at least two drawbacks. On the one hand, the position and the type of movement by simple pressure of the thumb can induce an untimely release of the magazine due to a false movement of the shooter, and on the other hand, the position of the thumb must be adapted to the right or left handed grip of the shooter.
[0006] Un des objectifs de la présente invention est donc de proposer un verrou de chargeur réduisant la probabilité de libération non désirée du chargeur. Selon des modes préférés de l'invention le mécanisme de verrou de chargeur doit permettre une utilisation ambidextre de l'arme concernée. [0006] One of the objectives of the present invention is therefore to provide a magazine lock that reduces the probability of unwanted release of the magazine. According to preferred embodiments of the invention, the magazine lock mechanism must allow ambidextrous use of the weapon concerned.
[0007] Idéalement, les dispositifs ambidextres doivent permettre une libération par un côté, sans induire de mouvement de l'autre côté. En effet, le bouton d'activation peut se trouver sous la paume ou sous l'index de la face opposée, ce qui pourrait induire une friction empêchant une libération aisée du verrou. [0007] Ideally, ambidextrous devices should allow release from one side, without inducing movement on the other side. Indeed, the activation button may be under the palm or under the index finger of the opposite face, which could induce friction preventing easy release of the lock.
Résumé de l'invention Summary of the invention
[0008] La présente invention concerne un mécanisme de déverrouillage de chargeur de pistolet comprenant au moins un bouton de commande disposé sur le flanc d'une poignée dans laquelle peut être inséré un chargeur, chaque bouton de commande étant fixé à une extrémité d'un levier de commande commandant translation d'une came de verrou disposée à l'avant ou à l'arrière de la poignée ladite came de verrou comprenant un verrou, coopérant en utilisation avec une surface d'arrêt disposée sur la surface avant ou arrière du chargeur pour verrouiller ou déverrouiller ledit chargeur, au moins un ressort maintenant la came de verrou en position de verrouillage du chargeur en absence de pression exercée sur le bouton de commande.

Description détaillée de l'invention Detailed description of the invention
[0022] La présente invention concerne un mécanisme de déverrouillage de chargeur, en particulier un mécanisme de déverrouillage de chargeur intégré à un pistolet semi-automatique. Cette invention représente une alternative au verrou décrit dans la demande PCT/EP2020/054624 du même demandeur. Cette demande concerne les formes de réalisation des figures 3 à 7. The present invention relates to a magazine release mechanism, in particular a magazine release mechanism integrated into a semi-automatic pistol. This invention represents an alternative to the lock described in application PCT/EP2020/054624 by the same applicant. This application relates to the embodiments of Figures 3 to 7.
[0023] Tel que représenté aux figures 1 et 2, la commande de verrou de chargeur 2 est disposée sur le flanc de la poignée 1. Tel que représenté sur ces figures, la commande de déverrouillage est obtenue en déplaçant cette commande 2 du haut vers le bas, et non par pression latérale sur un bouton poussoir. Ceci permet d'éviter qu'une pression mal contrôlée du pouce ne déverrouille le chargeur 3, malgré une position de la commande 2 à une position normalement occupée par le pouce du tireur lors de l'utilisation de l'arme. As shown in Figures 1 and 2, the loader lock control 2 is arranged on the side of the handle 1. As shown in these figures, the unlocking control is obtained by moving this control 2 from top to the bottom, and not by side pressure on a push button. This makes it possible to prevent poorly controlled thumb pressure from unlocking the magazine 3, despite a position of the control 2 in a position normally occupied by the shooter's thumb when using the weapon.
[0024] Tel que représenté aux figures 3 et 4, les boutons de commandes[0024] As shown in Figures 3 and 4, the control buttons
2,9 sont disposés aux bouts de deux leviers 4,5. Ces leviers permettent non seulement de positionner les boutons de commandes 2,9 à l'endroit permettant la meilleure ergonomie (distance entre l'arrière de la poignée et la dernière phalange du pouce), mais aussi d'augmenter la course nécessaire au déverrouillage du chargeur. Une course plus longue réduit les probabilités de déverrouillage non-désirés, tandis qu'une course plus courte améliore la facilité d'emploi. Des leviers équivalents 4,5 sont également présent dans le dispositif de l’invention représenté aux figures 8 et 9. 2.9 are arranged at the ends of two levers 4.5. These levers not only make it possible to position the control buttons 2.9 in the place allowing the best ergonomics (distance between the back of the handle and the last phalanx of the thumb), but also to increase the stroke necessary to unlock the charger. A longer stroke reduces the chances of unwanted unlocks, while a longer stroke short improves ease of use. Equivalent levers 4.5 are also present in the device of the invention shown in Figures 8 and 9.
[0025] Bien entendu, un seul levier et bouton de commande pourrait suffire à déverrouiller le chargeur et présenterait à lui seul l'avantage du mouvement de haut en bas, et la détermination d'une course de commande adéquate. Néanmoins, dans ce cas, l'arme ne pourrait être facilement adaptée à tous les tireurs et il faudrait des dispositifs spécifiques pour les "droitiers" et pour les "gauchers". Aussi, avantageusement, le verrou selon l'invention comprend un bouton de commande de chaque côté de la poignée. [0025] Of course, a single lever and control button could be sufficient to unlock the charger and would alone have the advantage of movement from top to bottom, and the determination of an adequate control stroke. Nevertheless, in this case, the weapon could not be easily adapted to all shooters and specific devices would be needed for "right-handers" and for "left-handers". Also, advantageously, the lock according to the invention comprises a control button on each side of the handle.
[0026] Comme on le voit aux figures 6 et 7, dans l’alternative de la demande PCT/EP2020/054624, le déverrouillage proprement dit est obtenu par la rotation d'une came 8 tournant autour d'un axe 11 . Cette came 8 comprend une surface d'arrêt 13 coopérant avec une surface d'arrêt 15 correspondante sur la face arrière du chargeur 3. As seen in Figures 6 and 7, in the alternative of application PCT / EP2020 / 054624, the actual unlocking is obtained by the rotation of a cam 8 rotating around an axis 11. This cam 8 comprises a stop surface 13 cooperating with a corresponding stop surface 15 on the rear face of the magazine 3.
[0027] Selon l’invention, la came tournante 8 a été remplacée par une came en translation 17, se déplaçant selon un mouvement représenté par une double flèche sur la figure 9 (les parties cachées de la came de verrou 17 ont été représentées en pointillé) According to the invention, the rotating cam 8 has been replaced by a cam in translation 17, moving according to a movement represented by a double arrow in Figure 9 (the hidden parts of the lock cam 17 have been represented in dotted)
[0028] Dans le cas d'un mécanisme en rotation et non ambidextre, comprenant un seul bouton de commande 2,9 et un seul levier 4,5, la rotation de la came de verrou 8 peut être simplement obtenue en rendant le levier 4,5 solidaire de ladite came de verrou 8. Dans ce cas, un unique ressort 6,12 agissant soit sur la came 8, soit sous le levier 4,5 suffit à ramener le verrou en position verrouillée après chargement. [0028] In the case of a rotating and non-ambidextrous mechanism, comprising a single control button 2.9 and a single lever 4.5, the rotation of the lock cam 8 can be simply obtained by making the lever 4 5 integral with said lock cam 8. In this case, a single spring 6.12 acting either on the cam 8 or under the lever 4.5 is sufficient to return the lock to the locked position after loading.
[0029] Dans le cas d'un mécanisme ambidextre, si les deux leviers 4,5 sont solidaires de la came 8, les deux boutons de commandes 2,9 se déplaceront solidairement. Ce mouvement solidaire peut poser des problèmes de fiabilité dans le cas où le bouton côté paume de la main du tireur se trouve à la base de l'index, ou sous une partie de la paume exerçant une forte pression sur le bouton correspondant. En effet, dans ce cas, la pression de la paume ou de la base de l'index pourrait empêcher le mouvement de déverrouillage, ou, pire de retour du verrou en position de verrouillage. Dans ce cas, il pourrait être compliqué de replacer un nouveau chargeur de façon fiable. Aussi, de façon avantageuse les deux leviers de commandes 4,5 actionnent la came de verrou par simple appui d'un ergot de levier de commande 10, sur un ergot 7 de came de verrou correspondant sur la came de verrou 8. In the case of an ambidextrous mechanism, if the two levers 4.5 are integral with the cam 8, the two control buttons 2.9 will move together. This united movement can pose reliability problems in the case where the button on the palm side of the shooter's hand is located at the base of the index finger, or under a part of the palm exerting strong pressure on the corresponding button. Indeed, in this case, the pressure of the palm or the base of the index could prevent the unlocking movement, or, worse, the return of the lock to the locking position. In this case, it could be complicated to replace a new charger reliably. Also, advantageously the two control levers 4.5 actuate the lock cam by simple pressing of a control lever lug 10, on a corresponding lock cam lug 7 on the lock cam 8.
[0030] Dans le cas du verrou 17 se déplaçant en translation, une surface[0030] In the case of the lock 17 moving in translation, a surface
18 solidaire de chaque levier de commande 4,5 actionne le verrou 17 en prenant appui sur un ergot 19 situé sur ledit verrou 17. En absence de pression sur les leviers de commande 16, le verrou 17 est maintenu en position par un ressort 22, et chaque levier de commande est maintenu indépendamment l’un de l’autre par des ressorts 20,21. 18 integral with each control lever 4.5 actuates the lock 17 by pressing on a lug 19 located on said lock 17. In the absence of pressure on the control levers 16, the lock 17 is held in position by a spring 22, and each control lever is held independently of one another by springs 20.21.
[0031] L'homme du métier comprendra aisément que si l'ergonomie idéale est bien obtenue en plaçant la came de verrou 17 à l'arrière de la poignée 1 (longueur des leviers sensiblement égale à la longueur d'un pouce), ce dispositif pourrait être transposé de façon symétrique à l'avant de la poignée. [0031] Those skilled in the art will easily understand that if the ideal ergonomics are indeed obtained by placing the lock cam 17 at the rear of the handle 1 (length of the levers substantially equal to the length of a thumb), this device could be transposed symmetrically to the front of the handle.
[0032] Dans de nombreux pistolets semi-automatiques récents, la fonction de guidage des pièces mobiles en générale, et de la glissière en particulier est découplée de la fonction de préhension de l’arme par l’utilisation d’un châssis métallique comprenant des rails sur lesquels coulisse la glissière lors du cycle de l’arme. Une carcasse comprenant la poignée supporte ce châssis. Cette poignée comprend un puit de chargeur dans lequel est inséré le chargeur. Avantageusement, la came de verrou 17 est guidée par un logement ménagé dans une partie 23 du châssis et non dans la carcasse, de façon à améliorer le positionnement de la tête du chargeur (et de ce fait, le positionnement de la cartouche à charger) par rapport à la glissière pour éviter les problèmes de rechargement lors du cycle de l’arme. [0032] In many recent semi-automatic pistols, the function of guiding the moving parts in general, and of the slide in particular, is decoupled from the gripping function of the weapon by the use of a metal frame comprising rails on which the slide slides during the cycle of the weapon. A carcass comprising the handle supports this frame. This grip includes a magazine well into which the magazine is inserted. Advantageously, the lock cam 17 is guided by a housing provided in a part 23 of the frame and not in the carcass, so as to improve the positioning of the head of the magazine (and therefore the positioning of the cartridge to be loaded) relative to the slide to avoid reloading issues when cycling the weapon.
