Definitions

  • the invention relates to a firearm, comprising a carcass carrying a movable slide supporting a movable barrel; a striker, the actuating device of said striker being constituted by a kinematic chain comprising a pivoting trigger in the carcass; and a lever engaged between the slide and the barrel and articulated in the carcass, this lever comprising a first stop intended to come into contact with a surface of the slide and a second stop intended to come into contact with a surface of the barrel.
  • the braking of the slide is more especially obtained by setting in motion towards the rear of the barrel of the weapon simultaneously with the slide.
  • 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.
  • its operation for certain types of cartridges makes it necessary to design a slide with a mass so small that the production becomes inaccessible.
  • a firearm according to the first paragraph and comprising a lever mounted between the slide and the barrel is described in GB-A-240.880.
  • the first stop intended to come into contact with a surface of the slide is located on the side of the lever directed towards the rear end of the slide while the second stop, intended to come into contact with the surface of the barrel is located on the side of the lever directed towards the front end of the slide.
  • the invention relates to a firearm, for example a pistol, provided with a device for braking the slide, the aim of which is to overcome said disadvantages.
  • this object is achieved by the fact that the first stop is intended to come into contact with a surface of the slide during only part of the recoil of this slide, this recoil causing pivoting of the lever until that the latter is no longer in contact with the surface, this first stop being directed towards the front end of the slide, while the second stop is located on the rear side of the lever and directed towards the rear end of the slide, so that during the above-mentioned pivoting, the barrel follows the slide, but at a lower speed given by the ratio of the lever, the lever thus forming braking means of the slide.
  • US-A-2,921,503 relates to a weapon in which the slide is braked, but the braking is not obtained by a lever but by friction.
  • US-A-2,705,847 relates to a firearm in which the slide is not braked, this weapon therefore not comprising a lever ensuring braking.
  • 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.
  • the stop 6 is at a distance L1 from the axis 2 while the stop 9 is at a distance L2 from this axis.
  • the slide 3 When firing the slide 3 is subjected, 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.
  • 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.
  • the slide is also braked by the forward thrust of the result of the pressures prevailing in the chamber.
  • FIGS. 4 to 7 is shown a weapon, more especially a pistol applying the device as illustrated in FIGS. 1 to 3.
  • This pistol is substantially constituted by a carcass 12 carrying the slide 3 itself supporting the barrel 4 as well as the striker 13.
  • 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 inter alia the trigger 16 which can tilt around an axis 17.
  • 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.
  • the device according to the invention constituted by the lever 1 which is articulated on the axis 2 housed in the carcass 12.
  • 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.
  • 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.
  • 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 hammer 14 so that it is driven against the striker 13 (see fig. 6).
  • 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.
  • 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.
