Description

La présente invention concerne un ressort de chien pour pistolets et similaires, ainsi que des pistolets équipés de ce ressort.The present invention relates to a dog spring for pistols and the like, as well as to pistols equipped with this spring.

Dans la plupart des pistolets connus, le ressort de chien est hélicoïdal et est inséré dans un logement prévu à cet effet dans la carcasse, parallèlement au logement du chargeur. Ce ressort agit sur le mécanisme d'armement à l'intervention d'une tige montée coaxialement audit ressort.In most known pistols, the dog spring is helical and is inserted into a housing provided for this purpose in the carcass, parallel to the housing of the magazine. This spring acts on the arming mechanism by means of a rod mounted coaxially with said spring.

Cette disposition connue complique le montage de l'arme, tout en en augmentant le coût et le poids. En outre, elle interdit la réalisation d'une crosse courte, souvent désirable pour des armes de poche.This known arrangement complicates the mounting of the weapon, while increasing its cost and weight. In addition, it prohibits the making of a short stock, often desirable for pocket weapons.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Ce but est atteint, conformément à l'invention, par un ressort constitué par un fil enroulé sous forme d'au moins une hélice se prolongeant de part et d'autre par un brin, l'un de ces brins étant destiné à prendre appui sur le chien et l'autre sur une partie de la carcasse de l'arme.This object is achieved, in accordance with the invention, by a spring constituted by a wire wound in the form of at least one helix extending on either side by a strand, one of these strands being intended to bear. on the dog and the other on a part of the carcass of the weapon.

Ce ressort est destiné à être monté dans l'arme de sorte que sa partie hélicoïdale soit enfilée autour d'un axe parallèle à l'axe du chien, l'extrémité au moins d'un desdits brins venant prendre appui sur le chien et l'autre brin sur la carcasse de l'arme.This spring is intended to be mounted in the weapon so that its helical part is threaded around an axis parallel to the axis of the dog, the end at least of one of said strands coming to bear on the dog and the other strand on the carcass of the weapon.

Dans une forme préférée de l'invention, ledit fil est enroulé sous forme de deux hélices coaxiales dont deux extrémités sont réunies par un brin de fil substantiellement en forme de U et dont les deux autres extrémités se prolongent chacune par un brin libre.In a preferred form of the invention, said wire is wound in the form of two coaxial helices, two ends of which are joined by a strand of wire substantially U-shaped and the two other ends of which each extend by a free strand.

Pour plus de clarté, une forme de réalisation de l'invention est décrite plus en détail ci-après, sans aucun caractère restrictif, référence étant faite aux dessins annexés, dans lesquels :

  • la figure 1 est une vue de face d'un ressort de chien selon l'invention; et
  • la figure 2 est une vue schématique d'un pistolet équipé du chien selon la figure 1.
For greater clarity, an embodiment of the invention is described in more detail below, without any restrictive character, reference being made to the appended drawings, in which:
  • Figure 1 is a front view of a dog spring according to the invention; and
  • FIG. 2 is a schematic view of a pistol equipped with the hammer according to FIG. 1.

Comme représenté, un ressort 1 selon l'invention est réalisé, dans cet exemple, par un fil enroulé sous forme de deux hélices coaxiales 2 et 3 réunies par un brin de fil 4 en forme de U et se prolongeant chacune par un brin libre en forme de L, respectivement 5 et 6.As shown, a spring 1 according to the invention is produced, in this example, by a wire wound in the form of two coaxial helices 2 and 3 joined by a strand of wire 4 in the shape of a U and each extending by a free strand in L shape, respectively 5 and 6.

A la figure 2 ont été représentés quelques éléments d'un pistolet automatique afin d'illustrer le montage du ressort selon la figure 1.In FIG. 2 are shown some elements of an automatic pistol in order to illustrate the mounting of the spring according to FIG. 1.

L'arme représentée comporte une carcasse 7 dont la partie crosse forme un logement pour un chargeur 8.The weapon shown comprises a carcass 7, the butt portion of which forms a housing for a magazine 8.

Sur cette carcasse est pivotée un chien 9, autour de l'axe 10.On this carcass is pivoted a dog 9, around the axis 10.

Le ressort 1 est monté de manière telle que ses hélices 2 et 3 entourent un axe 11, porté par la carcasse 7 et s'étendant parallèlement à l'axe 10 du chien 9. Le brin 4 vient prendre appui sur ce dernier, tandis que les branches 5 et 6 viennent s'appuyer sur la carcasse 7, plus particulièrement sur la branche externe de la partie crosse de cette dernière.The spring 1 is mounted in such a way that its propellers 2 and 3 surround an axis 11, carried by the carcass 7 and extending parallel to the axis 10 of the dog 9. The strand 4 comes to bear on the latter, while the branches 5 and 6 come to bear on the carcass 7, more particularly on the external branch of the butt portion of the latter.

La figure 2 montre clairement la simplification obtenue par rapport aux dispositions classiques mentionnées ci-avant.Figure 2 clearly shows the simplification obtained compared to the conventional arrangements mentioned above.

Comme le ressort 1 agit directement sur le chien, sans élément intermédiaire, une accélération plus rapide de ce dernier est obtenue, lors de l'actionnement de la détente 12, de par la masse relativement faible du ressort 1.As the spring 1 acts directly on the dog, without an intermediate element, a faster acceleration of the latter is obtained, when the trigger 12 is actuated, by the relatively small mass of the spring 1.

On voit également que l'utilisation d'un ressort selon l'invention permet de réaliser aisément une arme à crosse courte, vu le faible encombrement dudit ressort.It can also be seen that the use of a spring according to the invention makes it possible to easily produce a short stock weapon, given the small size of said spring.

Il est évident que des modifications de forme peuvent être apportées au ressort susdécrit, au prorata de la morphologie de l'arme à équiper.It is obvious that modifications of form can be made to the above-mentioned spring, in proportion to the morphology of the weapon to be equipped.
