Definitions

  • the invention relates to a handgun with a barrel fixed in use, a breech carrier and a breech head.
  • the breech head is fixed by a lock when it is fired and opened with a delay when the weapon is opened by the opening movement of the breech carrier.
  • a gas cylinder connected to the interior of the barrel has a gas piston which acts in an opening manner on the closure carrier.
  • Such a weapon is, for example, the small submachine gun sold by the applicant for the cartridge 4.6 x 30 mm.
  • Positional designations used in these documents are always related to the weapon held horizontally in the normal firing position, the firing direction being "forward".
  • the gas piston acts briefly on the breech holder with a short rod which is connected in one piece to it. This pushes it backwards, detaches it from the rod / gas piston component and pushes it on.
  • the gas piston which never leaves its gas cylinder, now returns to its original position through the action of a spring.
  • the closure carrier unlocks the closure head via a cam surface and the closure opens. The powder gases that have penetrated the gas cylinder are pushed back into the barrel.
  • Gas pressure loaders are also known (assault rifle 44), in which on the one hand the gas piston acts to the rear and on the other hand the powder gases are expelled from the gas piston to the front.
  • the reloading activity can be influenced by adjusting the corresponding nozzle and thus the rate of fire in the continuous fire can be adjusted.
  • recoil amplifiers which are similar to gas cylinders, are also known, particularly with machine guns.
  • the gas piston is formed by the barrel, which is pushed backwards by the escaping powder gases as well as by the recoil.
  • the recoil amplifier should act on the locked unit of lock and barrel accelerating and strengthening.
  • a recoil amplifier would be conceivable for ground locks, but in general it makes no sense, especially for small arms.
  • the recoil is generally too strong in the case of normal ordnance ammunition (for rifles or pistols) in order to permit a closure with a normal weight and / or normal closing spring. If mass locks are used, special braking mechanisms are used to reduce and delay the recoil.
  • gas pressure loaders are therefore used ("Desert Eagle” from IMI - EP 0 143 454). Compared to a locked recoil loader, this also has the advantage that the barrel can be installed rigidly and immovably, which increases the precision.
  • the gas piston is, among other things, firmly attached to the breech carrier.
  • gas piston is understood in the narrower sense only to mean that component which is actually located within the gas cylinder before the shot.
  • the breech holder is thus ready to fire on the gas cylinder.
  • a one-piece component made of gas piston and connecting rod is also considered a "gas cylinder” if the connecting rod is firmly attached to the closure carrier, ie the gas cylinder is not seated directly on the closure carrier.
  • the connecting feature is the fact that when the gas pistons are fired, they not only run back inside the gas cylinder, but also completely move out of the gas cylinder and move away from the gas cylinder with the breech carrier.
  • the gas cylinder and the gas piston make it possible to determine exactly when the weapon begins to open; in addition, that the opening always takes place with the necessary emphasis, which otherwise would not always be guaranteed with the relatively long, but overall weak cartridge.
  • This training also has the already mentioned "Desert Eagle” pistol, but there the gas piston acts as a recoil amplifier, while in the invention the breech carrier serves as a linkage, the weapon according to the invention cannot open by recoil alone, however high it may be.
  • the closure carrier with two opposite recesses into which - in the ready-to-fire state - pawls which are attached to the closure head fall.
  • the two opposite pawls can be very small, so that an excessively wide carriage is not required for a pistol, for example.
  • the pawls and, if appropriate, the breech carrier the weapon can be “tailor-made” for each cartridge, so to speak, without the need for fundamental changes to the structure.
  • the breech carrier is arranged around the barrel when the weapon is ready to fire, and the gas piston is attached to a vertical transverse wall of the breech carrier (claim 2).
  • the breech carrier extends to the front of the gas cylinder so that the gas piston can be made as short and light as possible. It proves particularly expedient to design the handgun as a pistol and the breech carrier as a carriage (claim 3).
  • the gas piston is located in the area of the barrel, that is to say at a point surrounded by the carriage, and so far forward that the ejection or tracking of the cartridge is not hindered.
  • gas piston requires a forward-facing extension with a smaller diameter, which closes the degassing opening when the gun is in the position ready to fire.
  • This extension automatically ensures with its conical transition to the actual gas piston that this "threads" into the gas cylinder every time the weapon is closed, even if it happens after a long time
  • a closure carrier with a pin has been found to be particularly useful, which pushes between the pawls in a ready-to-fire state and only allows them to slide out of the recesses when the closure carrier has moved a little to the rear from the closure head (claim 6).
  • the pin allows, depending on its design (conical or cylindrical) that the recoil participates to a greater or lesser extent in the loading process.
  • FIG. 1 is a vertical (a) and a horizontal (b) cross section through a pistol closure according to the invention, in a ready-to-fire condition,
  • Fig. 2 shows the closure of Fig. 1 shortly before unlocking or shortly after locking, vertically (a) and horizontally (b)
  • Fig. 3 shows the unlocked closure immediately before opening or immediately after closing before locking, vertically (a) and horizontally (b) cut
  • Fig.4 essential parts of the closure.
  • the breech or slide 1 of a gun is shown in two representations; in the upper (index a) each in central elevation and in the lower (index b) each in horizontal section. Details that are not essential here are omitted. In all figures, the left direction corresponds to the forward direction.
  • the carriage 1 has a substantially cuboid, elongated housing 3, the elevation of which - in the firing position of the pistol and viewed from the front - is slightly narrower in the horizontal direction than in the vertical direction.
  • the housing 3 is open on its underside and has a continuous web on both sides of this opening, which web runs in a groove of a handle (not shown). Otherwise, the housing 3 is closed all round, with the exception of a front opening 5, which serves to receive and pass a barrel 7.
  • This run passes through a vertical partition 9 integral with the breech housing 3, in such a way that the core axis of the barrel 7 passes through the partition 9 above its center.
  • the rear barrel end 7 is fastened in a sleeve 11, from which it is firmly surrounded.
  • the cuff 11 or the barrel 7 is - at least when the weapon is assembled - fastened in the handle of the weapon (not shown).
  • the carriage 1 is provided with a longitudinal groove 13, via which it is guided on the sleeve 11.
  • the barrel 7 is closed to the rear by a closure head 15, which in turn is connected to the housing 3 so as to be longitudinally movable.
  • the longitudinal movement of the closure head 15 is limited by a stop piece 27 fastened in the housing 3, which engages in a groove in the closure head 15.
  • the closure head 15 On its outside, the closure head 15 carries two opposite Pawls 17, the front of which is pivotable on
  • Locking head 15 are articulated.
  • the weapon In the position shown in FIG. 1, the weapon is immediately before the shot. If the cartridge 19 located in the barrel 7 is ignited, the recoil acts on the breech head 15. But this is based on the pawls 17 on the sleeve 11 and thus against the handle, so it remains closed.
  • the pawls 17 cannot pivot because their outer sections rest in a recess 21 in the housing 3 and their inside rests on a thickening 23 of a pin 25 connected to the housing 3.
  • the pin 25 is slimmer in the region of its front end 29.
  • the housing 3 After the shot, the housing 3 initially moves back until its stop piece 27 strikes against the rear end of the groove in the closure head 15. The housing 3 has also withdrawn the pin 25 firmly connected to it (FIG. 2). The slim pin end 29 then moves under the pawls 17, and the front ends of the recesses 21 press the pawls 17 towards the axis of the soul until they abut against the slim pin end 29 (FIG. 3). The housing 3 can now take the closure head 15 (no longer supported against the sleeve 11) with its further return, namely with the aid of the stop piece 27.
  • the recoil acting on the handle and the housing 3 will in practice not always move the housing 3 backwards into the open position (reloading position), ie initially over the entire movement distance granted by the stop piece 27 relative to the closure head 15 and then together with the locking head 15 to the reload position.
  • a strong closing spring acts on the housing 3 and presses it against the closure head 15.
  • the pawls 17 and the associated projections on the sleeve 11 and breech head 15 are formed so that the pawls 17 rest when the weapon is closed on a cylindrical part of the pin 25 and thus have no pushing the pin 25 backward effect. Such an effect occurs at most when the housing 3 (and thus the pin 25) has already moved a bit backwards relative to the closure head 15.
  • a recoil amplifier 31 is attached under the barrel 7, which is designed as a gas piston 35 and a gas cylinder 37 and is connected to the barrel interior 7 via a gas channel 39, 45.
  • a gas block 41 with a tight fit is pushed over the barrel 7 and bears on the one hand on a shoulder 33 of the barrel 7 and on the other hand on a spring ring 43.
  • the barrel 7 is provided with a gas extraction bore 39, the position of which will be discussed later.
  • the gas extraction bore 39 is extended by a vertically downward bore 45 in the gas block 41, which opens into the gas cylinder 37, which extends horizontally below and parallel to the core axis.
  • This gas cylinder is open to the rear and has a fine bore 47 on its front.
  • the gas piston 35 has a central, forwardly extending extension 49 which merges in a conical shape into the gas piston body which adjoins the rear.
  • the gas piston 35 sits in the gas cylinder 37 so that its extension 49 extends into the fine bore 47 in the rest position and seals it. Furthermore, the gas piston 35 is provided with a cylindrical outer wall which bears against the inner wall of the gas cylinder 37. The position of these parts ready to fire is shown in FIG. 1.
  • the bore 45 made in the gas block 41 opens out in the region of the transition from Gas piston body to the gas piston attachment 49 in the gas cylinder 37, so that there is always a free space connected to the interior of the barrel 7 around the gas piston 35.
  • the gas piston 35 is fixedly connected to the vertical partition 9 by means of a further spring ring 51.
  • the vertical partition 9 and thus the carriage housing 3 integrally connected to it is accelerated to the rear.
  • the housing 3 takes the pin 25 with it and its slender end 29 reaches the area of the pawls 17 which are pressed inwards by the front ends of the housing recesses 21.
  • the locking head 15 is hereby unlocked and taken away by the stop piece 27.
  • the distance between the inside of the rear housing end 3 and the rear closure head end remains the same, since the pawls 17 slide along the inside of the housing 3 and can therefore only move outwards again when they reach the area of the housing recesses 21.
  • the pawls 17 sit on the transition from the thickening 23 to the slender end 29 of the pin 25.
  • the locking head 15 can therefore only approach the rear end of the housing 3 again when the pawls 17 are in the region of the recesses 21.
  • the closure head 15 is held by the stop piece 27.
  • the gas extraction bore 39 is provided in the barrel 7 at a point which is so far in front of the cartridge chamber or so close to the muzzle that the following is ensured: the breech head 15 only moves significantly away from the rear barrel end when the projectile 7 has left and the gas pressure remaining in the barrel has dropped so far that the cartridge case (cartridge 19) reliably survives its removal without damage.
  • the pistol always moves backwards as a result of the recoil until it is intercepted by the shooter's hand.
  • the housing 3 is first accelerated together with the breech head 15 and moves further back when the shooter's hand has supported the handle (not shown) and thus the barrel 7 and the cartridge case.
  • the cartridge case now holds the closure head 15 and thus allows the thickening 23 of the pin 25 to be pulled out of the space between the two pawls 17. If the recoil is hard enough and the pistol is not is firmly clamped (which is hardly possible), the weapon would have to work without the recoil amplifier 31.
  • the locking distance (the distance of the possible relative movement between the breech head 15 and the housing 3, limited by the stop piece 27) will be chosen so that the recoil is not sufficient to open the weapon.
  • the function of the gun shown is therefore dependent on the recoil amplifier. Nevertheless, the pistol is not a gas pressure charger, but uses a braked ground lock with a recoil booster.
  • This arrangement ensures - as with a gas pressure charger that the closure only opens when that Projectile has left the barrel. While with one
