Description

Objet de l'inventionObject of the invention

La présente invention se rapporte à dispositif de sécurité de détente d'une arme à feu, en particulier d'un pistolet.The present invention relates to a trigger safety device for a firearm, in particular a pistol.

Etat de la techniqueState of the art

Il est connu dans le domaine des armes à feu de proposer une sécurité bloquant la queue de détente lorsque l'arme n'est pas utilisée. Dans le cas des armes de poings, où l'arme est tenue à une seule main, les risques de chute sont importants, en particulier en condition de combat. De ce fait, il est utile de sécuriser la queue de détente contre les risques de tir accidentels, même lorsque la sécurité n'est pas engagée. En effet, lorsque la sécurité n'est pas engagée, le risque de tir accidentel en cas de chute n'est pas négligeable.It is known in the field of firearms to offer a safety that blocks the trigger when the weapon is not in use. In the case of handguns, where the weapon is held with one hand, the risk of falling is significant, particularly in combat conditions. Therefore, it is useful to secure the trigger tail against the risk of accidental firing, even when the safety is not engaged. Indeed, when safety is not engaged, the risk of accidental shooting in the event of a fall is not negligible.

Le document brevet WO 2015/157753 décrit un système de sécurité dans lequel une queue de détente en deux parties permet de bloquer celle-ci en absence de pression du doigt sur la partie interne de la queue de détente. Ce dispositif présente néanmoins l'inconvénient d'avoir deux surfaces d'appuis sur le doigt du tireur, avec des risques de pinçage et d'encrassement important du dispositif. L'encrassement est d'autant plus important que les deux pièces de la queue de détente sont directement accessibles de l'extérieur. En cas de blocage entre les deux parties de la queue de détente, l'actionnement de celle-ci est rendu impossible. Un autre système de sécurité de détente d'une arme à feu est connu du document US 2017/299305 A1 .The patent document WO 2015/157753 describes a safety system in which a two-part trigger tail allows it to be blocked in the absence of finger pressure on the internal part of the trigger tail. This device nevertheless has the disadvantage of having two supporting surfaces on the shooter's finger, with risks of pinching and significant contamination of the device. Clogging is all the more significant as the two parts of the trigger tail are directly accessible from the outside. In the event of blockage between the two parts of the trigger tail, it becomes impossible to actuate it. Another trigger safety system for a firearm is known from the document US 2017/299305 A1 .

Description détaillée de l'inventionDetailed description of the invention

La présente description décrit essentiellement un exemple d'arme implémentant l'ensemble des aspects de la présente invention. L'homme du métier comprendra aisément que les différents aspects de l'invention, bien qu'utilisable séparément, présentent des synergies qui apparaîtront clairement au vus de cet exemple et des quelques variantes décrites.The present description essentially describes an example of a weapon implementing all aspects of the present invention. Those skilled in the art will easily understand that the different aspects of the invention, although usable separately, present synergies which will clearly appear in view of this example and the few variants described.

Un solide est dit équilibré lors de sa rotation autour d'un axe fixe si son centre de masse est sur l'axe de rotation et, de préférence si son axe de rotation est un axe principal d'inertie pour ce solide.A solid is said to be balanced during its rotation around a fixed axis if its center of mass is on the axis of rotation and, preferably if its axis of rotation is a main axis of inertia for this solid.

Par carcasse, nous entendons dans la présente description l'élément servant à la préhension et comprenant les éléments de fixation des différents éléments compris dans la partie inférieure de l'arme, ainsi que les éléments de fixation des pièces mobiles. Il peut s'agir d'une carcasse classique ou d'une carcasse intégrant un châssis distinct, amovible ou non du reste de la carcasse.By carcass, we mean in this description the element used for gripping and comprising the fixing elements of the different elements included in the lower part of the weapon, as well as the fixing elements of the parts mobile. It may be a classic carcass or a carcass incorporating a separate chassis, removable or not from the rest of the carcass.

La présente invention concerne un dispositif de sécurité bloquant la queue de détente 3 d'une arme à feu, en particulier un pistolet, empêchant le mouvement de la queue de détente 3 en absence de pression sur celle-ci. Contrairement à l'art antérieur ledit dispositif est intégré dans une cavité à l'intérieur de la queue de détente 3. La queue de détente 3 est avantageusement fixée rotative sur un axe 6 à l'extrémité inférieure d'un levier de détente 4 disposé dans la cavité à l'intérieur de la queue de détente 3. La queue de détente 3 peut alors basculer d'une position de repos où elle s'appuie par une surface avant 11 de sa cavité sur le levier de détente 4 à une position de tir où la queue de détente 3 prend appui par une surface arrière 10 de sa cavité sur le levier de détente 4.The present invention relates to a safety device blocking the trigger tail 3 of a firearm, in particular a pistol, preventing the movement of the trigger tail 3 in the absence of pressure thereon. Unlike the prior art, said device is integrated in a cavity inside the trigger tail 3. The trigger tail 3 is advantageously fixed rotatably on an axis 6 at the lower end of a trigger lever 4 arranged in the cavity inside the trigger tail 3. The trigger tail 3 can then switch from a rest position where it rests via a front surface 11 of its cavity on the trigger lever 4 to a position shooting where the trigger tail 3 is supported by a rear surface 10 of its cavity on the trigger lever 4.

Dans la position de tir, la pression sur la queue de détente 3 applique un couple sur le levier de détente 4 entre l'axe de queue de détente 6 et la surface arrière 10 de la queue de détente, induisant une rotation du levier de détente autour de son axe 7, induisant une translation de la tige de mise à feu 8 déclenchant le déplacement de la gâchette 9 de percuteur 18, libérant celui-ci et déclenchant le tir.In the firing position, pressure on the trigger tail 3 applies a torque to the trigger lever 4 between the trigger tail axis 6 and the rear surface 10 of the trigger tail, inducing rotation of the trigger lever around its axis 7, inducing a translation of the firing rod 8 triggering the movement of the trigger 9 of striker 18, releasing the latter and triggering the shot.

La queue de détente est solidaire d'une surface de blocage 2 qui, lorsque la queue de détente est au repos, peut prendre appui sur une surface 1 de la carcasse, empêchant la rotation du levier de détente 4. Les surfaces d'appui 1,2 sont disposées de façon à ce que seule une rotation de la queue de détente 3 par rapport au levier de détente 4 permette de débloquer ce dernier.The trigger tail is secured to a blocking surface 2 which, when the trigger tail is at rest, can rest on a surface 1 of the carcass, preventing the rotation of the trigger lever 4. The support surfaces 1 , 2 are arranged so that only a rotation of the trigger tail 3 relative to the trigger lever 4 makes it possible to unlock the latter.

L'avantage d'une telle disposition est de protéger au moins partiellement le dispositif de sécurité de l'encrassement d'éviter tout pincement de la peau du tireur et d'améliorer l'ergonomie du tir en ne devant appuyer que sur une seule surface d'appui.The advantage of such an arrangement is to at least partially protect the safety device from contamination, to avoid any pinching of the shooter's skin and to improve the ergonomics of shooting by only having to press on a single surface. support.

Avantageusement, la queue de détente est maintenue en position de repos par des moyens élastiques, tel que, de préférence, un ressort 5 ou une lame ressort (non représenté).Advantageously, the trigger tail is held in the rest position by elastic means, such as, preferably, a spring 5 or a leaf spring (not shown).

Avantageusement, de façon à éviter que l'inertie de la queue de détente 3 n'induise une rotation de celle-ci lors d'une chute, la queue de détente est équilibrée sur son axe. (i.e. son centre de masse est sur son axe de rotation 6 et de préférence l'axe de rotation 6 est un axe principal d'inertie de la queue de gâchette 3).Advantageously, in order to prevent the inertia of the trigger tail 3 from inducing rotation thereof during a fall, the trigger tail is balanced on its axis. (i.e. its center of mass is on its axis of rotation 6 and preferably the axis of rotation 6 is a main axis of inertia of the trigger tail 3).

De préférence, la carcasse est formée d'un support 20 en matière plastique et d'un châssis 17 métallique auquel les parties essentielles du mécanisme de la carcasse sont fixées (rails de glissière, mécanisme de mise à feu, sécurités,.... ), la surface d'appui 1 de la carcasse étant solidaire du châssis 17 plutôt que du support plastique, les contraintes dimensionnelles étant mieux contrôlées sur le châssis.Preferably, the carcass is formed of a support 20 made of plastic material and a metal frame 17 to which the essential parts of the carcass mechanism are fixed (slide rails, firing mechanism, safety devices, etc.). ), there support surface 1 of the carcass being integral with the chassis 17 rather than the plastic support, the dimensional constraints being better controlled on the chassis.

Avantageusement, la queue de détente comprend sur sa face avant une encoche 13 coopérant avec un coulisseau 14 permettant de bloquer le mouvement de rotation de la queue de détente, (sécurité de blocage de la queue de détente).Advantageously, the trigger tail comprises on its front face a notch 13 cooperating with a slide 14 making it possible to block the rotational movement of the trigger tail (safety for blocking the trigger tail).
