Definitions

  • the invention relates to a firearm comprising a housing with a receptacle for several cartridges or for a magazine with cartridges, a barrel unit arranged in the housing, which has a barrel with a muzzle opening and a cartridge chamber arranged at the opposite end, one opposite the housing in the longitudinal direction of the barrel Movable breech that is prestressed in the firing direction by means of a return spring for transporting cartridges from the receptacle or from the magazine into the cartridge chamber or for transporting cartridge cases to an ejection port and a gas braking device arranged in the housing, comprising a cylinder arranged parallel to the barrel, which has a gas extraction opening with connected to the interior of the barrel, and a piston movable within the cylinder and coupled to the breech.
  • the U.S 2002096042 A the U.S 2015276334 A or the U.S 2021116190 A each firearm with a gas brake device, which either dampens the rearward movement of the mass breech or delays the opening of the breech when the shot is fired.
  • a further problem with all weapons currently on the market with a mass breech is that the breech mass is guided on the outside of the weapon, usually on the top of the housing, due to its necessary size and also due to the conventional design in the prior art as a slide . This means that every time a shot is fired, the slide fully disengages, exposing the gun's internal parts directly to the environment. Depending on the field of application of the firearm, dust and dirt can easily get into the weapon and impair its further functionality.
  • the object of the present invention is therefore to further improve the weapon described in AT 519743 A4, so that a firearm is created which is even simpler in construction and has even greater functional reliability.
  • the weight of the weapon should be kept low and the entire locking mechanism should be stored inside the protective housing.
  • the number of parts should be reduced, which also reduces the manufacturing costs.
  • all movements of the locking mechanism should be as linear as possible when the shot is fired and during the reloading process.
  • the breech is arranged in a breech carrier unit, which is located completely inside the housing over the entire movement path during firing and the reloading process, the breech carrier unit holding the breech itself, two connecting sections guided parallel to the barrel in the housing and a coupling portion for coupling to the piston of the gas brake device.
  • the structure of the firearm can be significantly simplified by integrating the gas braking device. All moving parts, such as the bolt carrier unit and the piston, are linearly guided and move entirely within the receiver. Due to the gas brake device, the breech mass can also be designed to be very small and light, which has a positive effect on the overall weight of the weapon.
  • the gas braking device also offers the advantage that larger calibers with more powerful propellant charges can also be used. The resistance of the gas brake device is always adjusted automatically based on the propellant charge present so that the breech is kept closed until the cartridge has left the barrel.
  • the lock carrier unit is designed in one piece.
  • the bolt carrier unit is manufactured as a one-piece component. This also offers advantages for the user when disassembling and cleaning the weapon.
  • the gas extraction opening is arranged in the barrel near the end on the cartridge bearing side.
  • gas is fed from the propellant charge into the cylinder immediately after the shot is fired.
  • gas pressure is built up in the direction of the closure and in the opposite direction against the piston in the cylinder, which means that the effect of the gas braking device is always constant, regardless of the strength of the propellant charge. Pressure and counter-pressure balance out evenly at any possible gas pressure until the cartridge has left the barrel and the bolt can perform its backwards movement.
  • a cover which can be displaced in relation to the housing in the longitudinal direction of the barrel and which is pretensioned in the direction of its closed position by means of a spring, the cover having a driver section which projects inwards into the housing and which is used for the purpose of manual reloading can be coupled to the bolt carrier unit during the movement of the cover against the firing direction, but is decoupled from the bolt carrier unit when the cover is in its closed position.
  • This cover closes the housing above the barrel. During the firing and automatic reloading process, the cover remains closed at all times, which means that no dust or dirt can get inside the housing.
  • the cover can also be used for manual loading of the weapon via a longitudinal guide and a driver section, in that the driver section takes the bolt carrier unit backwards with it when the user pulls it back manually.
  • the driver section can, for example, be an inwardly protruding projection which can be brought into contact with a corresponding stop surface of the bolt carrier unit. Since the cover here also does not correspond to the classic slide that usually forms the majority of the breech mass, the cover can be made correspondingly light, which also has a positive effect on the total weight of the firearm.
  • the return spring is arranged around the barrel and is supported on the one hand on a non-moving part within the housing and on the other hand on the bolt carrier unit. This represents a particularly simple way of arranging the return spring that is required to bias the bolt carrier unit towards the closed position and to move the bolt carrier unit forward again from the rear, disengaged position during the reloading process.
  • the return spring is arranged around a guide rod arranged parallel to the barrel and connected to a non-moving part within the housing and is supported on the one hand on a non-moving part within the housing and on the other hand on the bolt carrier unit.
  • the return spring can also be guided on a corresponding guide rod, for example below the barrel and below the cylinder.
  • a spring is also required to preload the cover.
  • the spring for the cover can be placed on a guide rod and the recoil spring around the barrel, or vice versa.
  • the two required springs can also be placed elsewhere.

  • 2 shows a schematic longitudinal section through a firearm according to the invention in the form of a handgun with a closed breech
  • 3 shows a schematic longitudinal section through the firearm according to FIG Fig. 4
  • the firearm according to the invention shown schematically in an exploded view in FIG. 1 has a housing 1 .
  • a receptacle 2 for a magazine.
  • the trigger 17, the hammer 18 as well as the barrel unit 3 and the bolt carrier unit 12 are arranged in this housing and the upper side of the housing 1 is closed by a cover 15 which can be displaced in the longitudinal direction.
  • the barrel unit 3 comprises the barrel 4 with a front muzzle opening 5 and a cartridge chamber 6 arranged at the opposite end (see FIG. 2).
  • cylinder 9 of the gas braking device and guide rod 16 for return spring 7 are located in barrel unit 3.
  • Bolt carrier unit 12 includes actual breech 8 and a coupling section 14 rigidly connected to it via two connecting sections 13, on which piston 11 of the Gas braking device is fixed.
  • FIGS. 2 to 4 show the individual positions of the bolt carrier unit 12 before the shot is fired and during the reloading process in a schematic longitudinal sectional view.
  • FIG. 2 shows the situation before the shot is fired. A cartridge and a magazine filled with cartridges in the receptacle 2 are not shown.
  • the bolt carrier unit 12 Before the shot is fired, the bolt carrier unit 12 is in the front, closed position.
  • the breech 8 is pretensioned in the firing direction against the cartridge chamber 6 via the return spring 7 which acts on the coupling section 14 of the breech carrier unit 12 .
  • the bullet moves from the chamber 6 into the barrel 4.
  • the gas extraction opening 10 is located immediately adjacent to the chamber 6 and connects the interior of the barrel 4 to the cylinder 9 of the gas brake device.
  • the gas pressure builds up on the one hand in the opposite direction to the firing direction on the breech and on the other hand gas flows through the gas extraction opening 10 into the cylinder 9, whereby the gas pressure also acts in the firing direction on the piston 11, which via the coupling section 14 also acts on the breech 8 acts to keep it closed.
  • the pressure in the cylinder 9 and in the barrel 4 balance each other out, so that the breech 8 remains closed until the bullet leaves the barrel.
  • FIG. 4 shows the rear, disengaged position of the bolt carrier unit 12 .
  • the spent cartridge case has already been ejected and the return spring 7 begins to move the bolt carrier unit 12 back into the forward position, whereby another cartridge is conveyed from the magazine into the cartridge chamber 6, after which the position according to FIG. 2 is reached again.
