The design provides increased accuracy of shooting barrelless weapons while maintaining the traditional appearance of weapons.

Description

The utility model relates to firearms, namely to self-defense weapons. In a number of countries, the usual short-barreled weapon, i.e. pistols and revolvers. In revolvers, where the barrel is separated from the chamber (drum), there has always been a problem of obturation between them. The simplest solution is to minimize the gap between the drum and the barrel (but this increases the sensitivity to clogging). Modern revolvers often use the following method - the window in the revolver frame is made longer than the drum, which leads to the formation of a gap and guarantees free rotation of the drum even in the event of significant blockages, and the obturation is provided by pressing the drum to the barrel. The pressing force arises when passing with an interference fit the narrowing of the drum chamber located in front of the chamber next immediately in front of the cartridge placement area, i.e. the bullet, coming out of the cartridge, when moving forward due to friction, pulls the drum forward, pressing it to the barrel, eliminating the gap. This design is shown in the book of R. Adam "Personal firearms": Per. from English V. Altova. - M .: Mir, 1995. - 128 p., Pp. 58-59 (a section of the Smith-Wesson revolver is given).

In Russia, citizens are only allowed to use traumatic and gas weapons. Gas, in practice, when using cartridges permitted in the Russian Federation did not justify itself. Traumatic weapons are represented by revolvers and pistols "Makarych", "Naganych" and similar products adapted for the use of cartridges with elastic plastic bullets. Owing to their small calibers, their effectiveness is also extremely low.

In addition, barrelless weapons are permitted in which the limitation of power and, consequently, non-lethality occurs due to the fact that

The internal ballistics of the bullet should flow inside the sleeve. The presence of the barrel as a bullet-accelerating element is prohibited. The most famous representative of this group of products is the "Gun barrelless 4-charging" PB-4-Osa. (See passport ″ Self-defense weapon Complex ″ OCA ″, 1999)

The barrel in conventional firearms not only accelerates the bullet, but as it lengthens it reduces the muzzle pressure, which negatively affects the accuracy of the fire. Therefore, sports, sniper, hunting weapons usually have longer barrels than general army ones.

Attempts are known (to increase the charge) to make barrelless weapons by removing the barrel from the construct of the revolver.

In addition to the damaging effect for self-defense weapons, an important factor is the psychological impact. These samples, such as the Wasp or revolvers with a remote barrel, have a very specific appearance, easily recognizing them as non-lethal weapons, i.e. the psychological factor is reduced. In addition, the absence of a barrel guarantees high muzzle pressure and, as a result, reduced accuracy. Today, technical solutions are proposed for turning the barrel into a false barrel (RF patent No. 2243476, F41C 3/00, 2004), but the essence of this patent is reduced to breaking up the barrel into elements - spiral or flap, between which decompression slots are organized, but this dramatically reduces the rigidity of the barrel and technically significantly increases the complexity of manufacturing.

It is known that on conventional weapons to increase accuracy, the stiffness of the trunks is increased. An example of this is super-thick trunks of sports rifles.

The task to which the proposed utility model is directed is to create a relatively simple design,

increasing the accuracy of shooting barrelless weapons while maintaining the traditional appearance of weapons.

The problem is solved in that the barrelless self-defense weapon, comprising a housing with an ammunition holder, a trigger mechanism, is provided with a guide placed in front of the ammunition holder coaxially with it and installed separately from it with a significant decompression gap, which provides pressure relief from the cartridge into the atmosphere.

The difference between the proposed technical solution and similar solutions is that a guide is installed in front of the chamber, which, unlike the barrel, is not connected and not pressed to the chamber, but is pushed forward from it to form a decompression gap.

The task is the opposite of the problems existing in conventional revolvers described above, where the task is to transfer the pressure from the chamber to the barrel to the maximum for which the drum is pressed against the barrel. The task for turning the revolver into a barrelless weapon is solved by changing the configuration of the frame window to form a significant decompression gap between the drum and the barrel. Thus, pressure is released through this gap, pressure is not transmitted to the barrel, it loses its acceleration function and turns into a guide - “false barrel”, which increases accuracy and maintains its traditional appearance to make it difficult to recognize it as non-lethal. The barrel moves significantly away from the chamber, with the formation of a sufficient decompression gap, the frame configuration does not allow the drum to move and reduce the decompression gap. (The special configuration of the frame window for placing the drum differs from the standard rectangular one in that the drum does not hold onto the barrel due to the significant removal of material from the front upper part of the window, while the unstacked material of the front lower part of the window acts as a stop blocking the drum movement to the side trunk

this emphasis can be made in the form of a fixed sleeve around the axis of the drum or in another way).

In pistols, both automatic and non-automatic, a false barrel is created by separating the barrel from the chamber and installing it in a position coaxial with the chamber with a decompression gap between them. Here, as in conventional weapons, muzzle pressure will exist, it is not significant, but if necessary, its influence can be eliminated by friction of the bullet against the walls of the guide, for which a certain tightness should be ensured between them.

The proposed utility model is illustrated in the drawing, which shows in figure 1 - General view of self-defense weapons with a pistol layout; figure 2 is a General view of a weapon of self-defense with a turret layout.

The weapon (Fig. 1) includes a housing 1 with a chamber 2. A guide - a false barrel 3 is mounted coaxially with the chamber 2, and for the formation of a decompression gap 4 is moved forward from the chamber 2 by the amount of the gap. Trigger hook - 5.

The weapon (figure 2) includes a housing in the form of a frame 6 and a cartridge holder in the form of a drum 7 with a chamber 12, which is mounted on the axis 10. The false barrel (guide) 8, coaxial chamber 12, is separated from the drum 7 by a decompression gap 9. The trigger mechanism is equipped crochet 11.

The size of the gap depends on the caliber and power of the powder charge of the cartridge used. (So, on a 21 mm caliber revolver being prepared for production at the Barnaul cartridge plant, a gap of 5 mm is planned, which is quite decorative with this caliber, and the decompression gap will have an area larger than the caliber’s area, which will ensure effective pressure relief).

The proposed device works as follows: during the firing of a shot, the bullet accelerates inside the cartridge, the sleeve of which serves as the barrel, overcomes the decompression gap 4 and, moving

forward, it enters the coaxially located guide - false barrel 3, the powder gases are discharged through the decompression gap 4 and cease to accelerate the bullet. While the bullet moves inside the guide 3, the pressure is finally released, and when the bullet 3 exits the guide 3, the bullet practically does not have any muzzle pressure harmful to the accuracy of firing.

When the revolving arrangement (figure 2), the window configuration of the frame 6 does not allow the drum 7 to move towards the false barrel - guide 8, thus maintaining a constant value of the decompression gap 9.
