Description

L'invention concerne un dispositif pour le freinage de la glissière d'une arme à feu dans laquelle ce freinage est, plus spécialement obtenu par la mise en mouvement vers l'arrière du canon de l'arme simultanément avec la glissière.The invention relates to a device for braking the slide of a firearm in which this braking is, more especially obtained by setting in motion towards the rear of the barrel of the weapon simultaneously with the slide.

Il s'agit donc d'un principe de fonctionnement où le canon n'est ni fixé dans la carcasse (ce qui est le cas dans le principe du "blow back"), ni solidaire de la culasse (ce qui est le cas, dans les premiers millimètres de recul, dans le principe du court recul du canon).It is therefore a principle of operation where the barrel is neither fixed in the carcass (which is the case in the principle of "blow back"), nor integral with the breech (which is the case, in the first millimeters of recoil, in principle of the short recoil of the barrel).

Le premier principe de fonctionnement exige un poids de glissière plus important d'où une arme à poids élevé, la deuxième possibilité exige un dispositif de verrouillage de la glissière au canon pouvant solidariser la glissière au canon au début du recul de la glissière pour libérer la glissière du canon après un temps très réduit, ce dispositif présentant une construction plus complexe. De plus son fonctionnement pour certains types de cartouches oblige à concevoir une glissière d'une masse tellement faible que la réalisation devient inaccessible.The first operating principle requires a greater slide weight, hence a high-weight weapon, the second possibility requires a locking device for the barrel slide which can secure the slide to the barrel at the start of the recoil of the slide to release the barrel slide after a very short time, this device having a more complex construction. In addition, its operation for certain types of cartridges makes it necessary to design a slide with a mass so small that production becomes inaccessible.

L'invention vise un dispositif de freinage de la glissière d'une arme par exemple un pistolet dont le but est de pallier lesdits désavantages.The invention relates to a device for braking the slide of a weapon, for example a pistol, the aim of which is to overcome said disadvantages.

Conformément à l'invention, ce but est atteint par un dispositif pour le freinage d'une glissière d'une arme à feu, du type comprenant une carcasse portant une glissière mobile supportant un canon mobile et un percuteur, le dispositif d'actionnement dudit percuteur étant constitué par une chaîne cinématique comprenant une détente pivotant dans la carcasse, caractérisé en ce qu'entre la glissière et le canon est engagé un levier articulé dans la carcasse, ce levier comprenant vers l'avant une butée venant en contact avec une surface de la glissière pendant une partie seulement du recul de cette glissière, ce recul causant un pivotement du levier jusqu'à ce que ce dernier ne soit plus en contact avec la surface, ce levier comprenant également vers l'arrière une butée venant en contact avec une surface du canon de sorte que pendant le pivotement susdit, le canon suit la glissière, mais à une vitesse moindre donnée par le rapport du levier L2/L1.According to the invention, this object is achieved by a device for braking a slide of a firearm, of the type comprising a carcass carrying a movable slide supporting a movable barrel and a striker, the actuation device of said striker being constituted by a kinematic chain comprising a pivoting rebound in the carcass, characterized in that between the slide and the barrel is engaged a lever articulated in the carcass, this lever comprising forward a stop coming into contact with a surface of the slide during only part of the recoil of this slide, this recoil causing the lever to pivot until the latter is no longer in contact with the surface, this lever also comprising towards the rear a stop coming into contact with a surface of the barrel so that during the above-mentioned pivoting, the barrel follows the slide, but at a lower speed given by the ratio of the lever L2 / L1.

Pour plus de clarté, un exemple de réalisation d'un dispositif selon l'invention est décrit ci-après à titre illustratif et non restrictif, en se référant aux dessins annexés dans lesquels :

  • la figure 1 représente, très sommairement le dispositif selon l'invention;
  • les figures 2 et 3 sont des vues semblables à celle de la figure 1, le dispositif selon l'invention se trouvant dans deux autres positions caractéristiques;
  • la figure 4 représente en coupe longitudinale partielle une arme, en l'occurrence un pistolet, dans laquelle le dispositif selon l'invention est appliqué, l'arme étant représentée en position armée;
  • la figure 5 représente à plus grande échelle une coupe selon la ligne V-V de la figure 4;
  • les figures 6 et 7 représentent des vues semblables à celle de la figure 4 pour deux autres positions caractéristiques de l'arme.
For greater clarity, an exemplary embodiment of a device according to the invention is described below by way of illustration and without limitation, with reference to the appended drawings in which:
  • Figure 1 shows, very briefly the device according to the invention;
  • Figures 2 and 3 are views similar to that of Figure 1, the device according to the invention being in two other characteristic positions;
  • FIG. 4 shows a partial longitudinal section of a weapon, in this case a pistol, in which the device according to the invention is applied, the weapon being shown in the armed position;
  • Figure 5 shows on a larger scale a section along the line VV of Figure 4;
  • Figures 6 and 7 show views similar to that of Figure 4 for two other characteristic positions of the weapon.

Dans les figures 1 à 3 est représenté d'une manière schématique le dispositif selon l'invention, lequel est substantiellement constitué par un levier 1 articulé autour d'un axe 2, ledit levier 1 étant engagé entre la glissière 3 et le canon 4 d'une arme.In Figures 1 to 3 is shown schematically the device according to the invention, which is substantially constituted by a lever 1 articulated around an axis 2, said lever 1 being engaged between the slide 3 and the barrel 4 d 'a weapon.

Dans la figure 1, l'arme se trouve en position de repos. La glissière 3 a été amenée en butée contre la tranche arrière du canon 4 sous l'effet d'un ressort 7. Le mouvement conjoint vers l'avant, sous l'effet du ressort de rappel 10 et des inerties de la glissière 3 et du canon 4, a été stoppé par le relèvement du levier 1 qui se trouve finalement immobilisé par sa butée 6 en appui sur la surface 5 de la glissière 3 d'une part et par sa butée 9 en appui sur la surface 8 du canon 4 d'autre part. Dans le canon 4 se trouve la balle 11.In Figure 1, the weapon is in the rest position. The slide 3 was brought into abutment against the rear edge of the barrel 4 under the effect of a spring 7. The joint movement forward, under the effect of the return spring 10 and the inertia of the slide 3 and barrel 4, was stopped by raising the lever 1 which is finally immobilized by its stop 6 bearing on the surface 5 of the slide 3 on the one hand and by its stop 9 bearing on the surface 8 of the barrel 4 on the other hand. In the barrel 4 is the bullet 11.

La butée 6 se trouve à une distance L1 de l'axe 2 tandis que la butée 9 se trouve à une distance L2, de cet axe.The stop 6 is at a distance L1 from the axis 2 while the stop 9 is at a distance L2 from this axis.

Au moment du tir la glissière 3 est assujettie, d'une manière traditionnelle, à une force de recul F exercée par la pression. Selon l'invention, la glissière 3 transmet cet effort via la surface 5 sur la butée 6 du levier 1.When firing the slide 3 is subject, in a traditional manner, to a recoil force F exerted by pressure. According to the invention, the slide 3 transmits this force via the surface 5 on the stop 6 of the lever 1.

Ce dernier, en pivotant autour de son axe d'articulation 2, pousse avec sa butée 9 contre la surface 8 du canon 4 entraînant ainsi ce canon 4 également vers l'arrière.The latter, by pivoting about its hinge axis 2, pushes with its stop 9 against the surface 8 of the barrel 4 thus causing this barrel 4 also backwards.

De ce qui précède il résulte que le recul de la glissière 3 est freiné non seulement par la masse propre de la glissière 3 mais également par la masse du canon 4.From the above it follows that the recoil of the slide 3 is braked not only by the mass of the slide 3 but also by the mass of the barrel 4.

Ce canon opère son mouvement vers l'arrière dès le début du recul mais à une vitesse plus faible que la glissière, donnée théoriquement par le rapport L2/L1.This gun operates its movement backwards from the start of the recoil but at a lower speed than the slide, theoretically given by the L2 / L1 ratio.

De plus, dans le cas d'armes utilisant des cartouches avec collet, la glissière est également freinée par la poussée vers l'avant de la résultante des pressions régnant dans la chambre.In addition, in the case of weapons using cartridges with a collar, the slide is also braked by the forward thrust of the result of the pressures prevailing in the chamber.

Cette situation se poursuit jusque dans la position où l'extrémité libre du levier 1 est basculée en dessous de la glissière 3, voir figure 2, après quoi le freinage de la glissière 3 continue sous l'influence seulement de la masse de la glissière 3 et l'effort croissant développé par le ressort 7. La masse du canon 4 est devenue sans effet à ce moment sur le freinage de la glissière 3. Cette situation est illustrée schématiquement dans la figure 3.This situation continues until the position where the free end of the lever 1 is tilted below the slide 3, see FIG. 2, after which the braking of the slide 3 continues under the influence only of the mass of the slide 3 and the increasing force developed by the spring 7. The mass of the barrel 4 became ineffective at this time on the braking of the slide 3. This situation is illustrated diagrammatically in FIG. 3.

Dans les figures 4 à 7 est représenté une arme, plus spécialement un pistolet appliquant le dispositif tel qu'illustré dans les figures 1 à 3.In FIGS. 4 to 7 is shown a weapon, more specifically a pistol applying the device as illustrated in FIGS. 1 to 3.

Ce pistolet est substantiellement constitué par une carcasse 12 portant la glissière 3 supportant elle-même le canon 4 ainsi que le percuteur 13.This pistol is substantially constituted by a carcass 12 carrying the slide 3 itself supporting the barrel 4 as well as the striker 13.

Un chien 14 pivotant dans la carcasse 12 peut venir heurter ledit percuteur 13 sous l'effet d'un ressort, non représenté sur les dessins, à l'intervention d'une chaîne cinématique schématisée en 15 comprenant entre autre la détente 16 pouvant basculer autour d'un axe 17.A dog 14 pivoting in the carcass 12 can strike said striker 13 under the effect of a spring, not shown in the drawings, by means of a kinematic chain shown schematically in 15 comprising, among other things, the trigger 16 which can tilt around an axis 17.

Le canon 4 présente un talon 18 dans lequel est pratiqué un trou borgne 19 logeant un ressort 20 dont l'extrémité arrière s'appuie sur la carcasse 12.The barrel 4 has a heel 18 in which a blind hole 19 is made, housing a spring 20, the rear end of which rests on the carcass 12.

Devant le talon 18 est situé le dispositif selon l'invention constitué par le levier 1 qui est articulé sur l'axe 2 logé dans la carcasse 12.In front of the heel 18 is located the device according to the invention constituted by the lever 1 which is articulated on the axis 2 housed in the carcass 12.

Ledit levier 1 est substantiellement constitué par un élément en forme de U dont la partie centrale 21 constitue, vers l'arrière, la butée 9 en contact avec la surface 8 du talon 18 du canon 4 tandis que les ailes 22 et 23 du levier 1 constituent, ensemble, vers l'avant, la butée 6 en contact avec la surface 5 de la glissière, en l'occurrence des nervures internes 24, 25 de la glissière 3.Said lever 1 is substantially constituted by a U-shaped element whose central part 21 constitutes, towards the rear, the stop 9 in contact with the surface 8 of the heel 18 of the barrel 4 while the wings 22 and 23 of the lever 1 together constitute, towards the front, the stop 6 in contact with the surface 5 of the slide, in this case internal ribs 24, 25 of the slide 3.

Le fonctionnement de l'arme telle que représentée dans les figures 4 à 7 est simple et comme suit.The operation of the weapon as shown in Figures 4 to 7 is simple and as follows.

Après introduction du chargeur 26 dans la crosse 27 de l'arme, une munition 11 est amenée dans la chambre du canon 4 par une manoeuvre manuelle connue en soi de la glissière 3, laquelle a également pour effet d'armer le chien 12 tel que représenté à la figure 4.After insertion of the magazine 26 into the stock 27 of the weapon, a munition 11 is brought into the barrel chamber 4 by a manual operation known per se from the slide 3, which also has the effect of arming the dog 12 such as shown in figure 4.

L'arme ainsi préparée est prête au tir. Le mouvement de la détente 16 dans le sens de la flêche F1 à pour effet, via la chaîne cinématique 15, de libérer le chien 14 de sorte qu'il est entraîné contre le percuteur 13 (voir fig. 6).The weapon thus prepared is ready to fire. The movement of the trigger 16 in the direction of the arrow F1 has the effect, via the kinematic chain 15, of releasing the dog 14 so that it is driven against the striker 13 (see fig. 6).

Suite au départ de la balle 11 et sous l'influence de l'explosion, la glissière 3 est refoulée vers l'arrière, et son mouvement a pour effet que le levier 1 bascule autour de son axe d'articulation 2 par l'effet des nervures 24, 25 excercé sur les ailes 22, 23 dudit levier 1.Following the departure of the ball 11 and under the influence of the explosion, the slide 3 is driven backwards, and its movement has the effect that the lever 1 rocks around its axis of articulation 2 by the effect ribs 24, 25 exerted on the wings 22, 23 of said lever 1.

Etant donné que le levier se situe entre la glissière 3 et le canon 4, ce dernier suit le mouvement de la glissière 3 par le fait que la partie centrale 21 dudit levier 1 bute contre le talon 18 du canon 4.Since the lever is located between the slide 3 and the barrel 4, the latter follows the movement of the slide 3 by the fact that the central part 21 of said lever 1 abuts against the heel 18 of the barrel 4.

Il s'en suit qu'à ce moment la masse du canon 4 ainsi que la poussée agissant vers l'avant dans le cas de cartouches avec collet interviennent complémentairement à la masse de la glissière 3, au freinage de cette dernière, et cela jusqu'à ce que le levier 1 soit basculé dans la position telle que représentée à la figure 7, position dans laquelle l'extrémité libre des ailes 22 et 23 du levier 1 se situe en dessous des nervures 24, 25 de la glissière tandis que l'extrémité libre de la partie 21 du levier 1 reste toujours contre le talon 18 du canon 4 lequel est retenu, par l'autre extrémité arrière dudit talon, contre la carcasse 12 de l'arme, le ressort 20 étant comprimé.It follows that at this time the mass of the barrel 4 as well as the thrust acting forward in the case of cartridges with collar intervene in addition to the mass of the slide 3, when the latter brakes, and this until 'that the lever 1 is tilted into the position as shown in Figure 7, position in which the free end of the wings 22 and 23 of the lever 1 is located below the ribs 24, 25 of the slide while the the free end of the part 21 of the lever 1 always remains against the heel 18 of the barrel 4 which is retained, by the other rear end of said heel, against the carcass 12 of the weapon, the spring 20 being compressed.

La glissière 3 continue seule son mouvement vers l'arrière afin d'éjecter la douille de la munition tirée; de refouler le chien 14; de mettre le ressort, non représenté dans les dessins et en relation avec le chien, sous tension; et de recharger la chambre du canon 4 avec une nouvelle munition 11 provenant du chargeur 26.The slide 3 continues its movement alone towards the rear in order to eject the cartridge case from the fired ammunition; to repress the dog 14; to put the spring, not shown in the drawings and in relation to the dog, under tension; and reload the chamber of the barrel 4 with new ammunition 11 from the magazine 26.

Finalement la glissière 3 est ramenée en contact, vers l'avant, contre le canon par le ressort 7 pour revenir, poussée par le ressort 20, dans la position de la figure 4.Finally the slide 3 is brought back into contact, towards the front, against the barrel by the spring 7 to return, pushed by the spring 20, into the position of FIG. 4.

Pendant ce mouvement vers l'avant de la glissière 3 le levier 1 s'installe de nouveau entre la glissière 3 et le canon 4.During this forward movement of the slide 3 the lever 1 is installed again between the slide 3 and the barrel 4.

Il est évident que le rapport L1/L2 du levier 1 dépend de la munition employée.It is obvious that the ratio L1 / L2 of lever 1 depends on the ammunition used.

Le dispositif selon l'invention est donc d'une construction très simple ce qui procure une grande sécurité de fonctionnement. Ce dispositif présente en outre l'avantage de laisser, à tout instant du cycle cinématique, les pièces en mouvement (canon 4 et glissière 3) parfaitement alignées, ce qui permet une usure minimale et régulière de la glissière 3 et du canon 4 entre eux et par rapport à la carcasse 12.The device according to the invention is therefore of a very simple construction which provides great operating safety. This device also has the advantage of leaving the moving parts (barrel 4 and slide 3) perfectly aligned at all times during the kinematic cycle, which allows minimal and regular wear of the slide 3 and the barrel 4 between them. and relative to the carcass 12.

Il est évident que l'invention n'est nullement limitée à l'exemple de réalisation décrit ci-avant mais que de nombreuses modifications peuvent être apportées au dispositif susdécrit sans pour autant sortir du cadre de l'invention.It is obvious that the invention is in no way limited to the embodiment described above but that numerous modifications can be made to the above-described device without departing from the scope of the invention.
