Description

The invention relates to weapons technology, namely to small arms such as a carbine capable of firing pistol cartridges and using a bolt-type shutter.

Prior art

The well-known pistol with a knee-lever shutter P00, invented by G. Luger, which was adopted by the Swiss army in 1900 in caliber 7.65 mm (7.65 × 21 mm Luger) and was further modernized by Luger to type P08 for a more powerful 9 mm caliber. The new P08 pistol was adopted by the army of the German Empire in 1908 as the main weapon and was produced in Germany from 1908 to 1952 (data are widely available on the Internet http://en.wikipedia.org/wiki/Luger_P08_pistol, http: // www .bimbel.de / artikel / artikel-45.html, https://www.google.com/search?q=luger+p08+blueprints&hl=en&newwindow=1&client=firefox&sa=X&rls=org.mozilla:ru:official&prmd=imvns&tbm : = isch & tbo = u & sollrce = univ & ei = RNp0UJHcCMHetAbH3IDIAQ & ved = OCC4QsAQ & biw = 1024 & bih = 425 # q = luger + p08 + blueprints & hl = en & newwindow = l & client =: flretms b & ru = m & r > .r_gc.r_pw.r_qf. & fp = c95fbfefbba31700 & biw = 853 & bih = 380). Later, the company "Mauser" from 1971 to the 80s of the last century resumed production of this pistol, in which locking is carried out by a folding knee-lever bolt (position 1 of Figure 1). After the shot, the pressure inside the barrel bore presses in all directions, which leads, on the one hand, to the movement of the bullet along the barrel and, on the other hand, forces the bolt to move backward (position 2 of FIG. 1). But the shutter is locked due to a biaxially elongated knee-lever pair, until it collides with curved cutouts on the handle (position 3 of FIG. 1). This makes it open, and the remaining energy is enough to fully open the knee-lever shutter to eject the sleeve (position 4 of Figure 1). Now the magazine is empty and a new cartridge is fed when the shutter moves forward. The energy for this forward movement comes from the shutter spring. Thus, the system is again in the initial position 1 (Figure 1) and is ready to fire again. A disadvantage of the known technical solution is the inability to ensure the movement of an elongated barrel for a weapon such as a carbine due to the fact that in order to provide a backward movement of a longer, and therefore heavier barrel, more energy is required than the POS knee-lever shutter due to the energy from a shot cartridge 9 mm caliber, i.e. in this case, the weapon function will not be performed. At the same time, the POS pistol cannot be considered the closest analogue, since the carbine belongs to another class of weapons.

Disclosure of invention

The claimed invention is aimed at solving the problem of creating a hunting carbine based on a pistol, i.e. carbine for a pistol cartridge 9 mm Luger with knee-lever bolt. The carbine has a knee-lever lock and is equipped with an integrated gas engine with a valve for adjusting gas pressure. The gas engine allows the barrel with the slider and the knee-lever bolt to be moved back an additional distance, reaching a distance of 12 mm, sufficient to open the knee-lever bolt. Using a valve with two different openings makes it possible to use a silencer when firing.

To achieve this, when creating such a carbine, the mechanism of the P08 pistol was preserved, but to ensure the movement of the elongated barrel, this mechanism was equipped with an integrated gas engine. When firing a jet of gas with excess energy leaves the gas hole located behind the chamber. After the shot is fired, the bullet begins to move along the barrel. When a bullet passes through a gas hole, gas enters through it into the gas block, which is mounted on the barrel. Under gas pressure, the piston leaves the opening of the gas block, hits a hardened plate fixed in the front of the box, moves the knee-lever lock and the barrel with the slider back by 8 mm during the time when its protrusion (pin) of the extractor leaves its guide holes in the gas block, and the pressure decreases so much that it can no longer press on the piston, because Now gas under pressure exits the gas block through the guide hole. Upon impact, the system has enough power due to an additional impact, which causes the barrel to move backward by an additional 4 mm (Figure 2).

T.O. with a slider stroke of 8 mm, the total backward displacement of the barrel is 12 mm, which is sufficient to open the knee-lever shutter to eject the sleeve and then reload. By supplying the gas chamber with a valve with two different openings (with different diameters), you can adjust the gas pressure inside the system by turning the valve at different angles (for example, 90 or 180 degrees) (for example, using a coin), inserting it into the slot (recess) on the outside surface (end) of the spring retainer, thereby increasing or decreasing the pressure and allowing, in the latter case, to use a silencer with a carbine. The invention allows recharging in automatic mode.

The implementation of the invention

The claimed solution can be implemented as follows. The design of a hunting carbine for a pistol cartridge with a knee-lever bolt uses the standard knee-lever mechanism of the POS pistol. When firing a gas jet with excess energy leaves the gas hole (1) located behind the chamber. After the shot is fired, the bullet (2) begins to move along the barrel (3) (Figure 2). When the bullet passes the gas hole (1), a certain amount of gas pressure enters through the gas hole (1) into the gas block (4), which is mounted on the barrel. The gas block (4) has a piston (5) that exits the hole under gas pressure. The piston (5) hides the hardened plate (8), which is fixed in front of the box (9) (Figure 2).

This will allow the barrel (3) with the slider and the knee-lever bolt to be moved back by 8 mm, until its protrusion (pin) of the extractor (6) leaves its guide hole (7) in the gas block (4) and the pressure can no longer press on it , because now gas under pressure exits the gas block (4) through the guide hole (7).

Now the system has enough additional power due to an additional blow. This causes the barrel to move back an additional 4 mm. T.O. with a slider stroke of 8 mm, the total rearward displacement of the barrel is 12 mm. Thus, now there is enough progress to reliably open the knee-lever shutter for ejecting the sleeve and subsequent reloading.

The claimed solution in the form of a device for a pistol cartridge with a knee-lever shutter can work in two different modes due to the design of the valve (10) (Figure 3) for adjusting the gas pressure inside the system. The valve has two different holes, its position in the system can be changed using the spring retainer (11) (Figs. 4, 5), which is inserted into the valve. Turning the spring retainer 90 degrees closes the system, which leads to a reduction in the pressure in it of firing with a silencer. When rotated 180 degrees, the hole increases, providing more pressure for firing without a silencer and a greater range.

Thus, a hunting carbine for a pistol cartridge with a knee-lever bolt differs in that it is actually equipped with a gas engine, and the standard knee-lever mechanism of the P08 pistol is used as a knee-bolt bolt. In this case, the energy of the gas jet from the shot is used as a gas engine, which enters through the gas hole in the gas block mounted on the barrel, equipped with a piston that exits the hole under gas pressure and strikes the hardened plate fixed in front of the box, shifting the barrel with the slider and the knee-lever lock back to a distance sufficient to open the knee-lever shutter to eject the sleeve and subsequent reloading. The gas hole is provided with a valve with two holes and the ability to rotate the valve to use one of the holes. The valve can be rotated by providing a valve with a slot in which platinum can be inserted to rotate the valve 90 degrees, providing a reduction in gas jet pressure and the possibility of using a silencer, or 180 degrees for using a carbine without a silencer.

Industrial applicability

The device can be used for hunting. It is made by known methods from known materials commonly used for the manufacture of small arms. The tests carried out confirm the achievement of the task, which indicates the compliance of the claimed technical solution with the patentability requirement "industrial applicability".
