Pistol

The device has a mechanical drive for transposition of the self-defense facilities from the concealed state to the active position for repulsion of an outer attack, mechanical tie-rod with movable components fitted on it, one end of the tie-rod is connected to the object being transposed, the other - to the power drive providing transposition of the tie-rod relative to the movable components fitted on it. At a tension of the tie-rod the movable components are subjected to a squeezing force and form a rigid structure, as a result, the self-defense facility connected to the tie-rod is transposed. The device for attachment has an appliance for mechanical squeezing of the body or a part of the body that can change the degree of body squeezing. In the traveling position the degree of mechanical squeezing is minimal. When the self-defense facilities are brought to the fighting position the degree of mechanical squeezing of the body or a part of the body is enhanced, and the device for attachment is tightly fixed on the body, for example, on the arm.

The recoil-checking mechanism for weapon shooting off a propellant charge is featured by production of force of counter-action directed forward simultaneously with absorption of the recoil force directed backward after initiation of the translational motion of the propellant charge. The counter-action force directed forward is produced by imparting forward motion to the first mass at a shot by the propellant charge and essentially by simultaneous imparting of backward motion to the second mass for absorption of the recoil force. In one of the mechanisms the weapon barrel may serve as the first mass, gases from detonation of the propellant charge in the shell are fed to the reaction bulk between the barrel and the breech. These gases move the barrel forward overcoming the action transferring the spring force and transferring the counter-action force directed forward to the weapon frame. Practically simultaneously the recoil from detonation of the shell together with the gases in the reaction bulk move the breech backward, opposite the spring absorbing the energy.

The holster of the short-barreled weapon has a casing, side walls, a through duct is made in one of the walls, fixture for holding the weapon by the trigger bow made in the form of a key fastened by the upper end to the holster side wall at an angle to the vertical, providing a reliable holding of the bow in the holster, sliding of the weapon on the key flange at placement of the weapon in the holster space and removal of the key flange from the bow at pressing of the key by a finger, and the fixture for fastening the holster to the belt a toothed disk with an inner engagement fixed on the holster, engageable with a toothed sector with the aid of a movable joint installed on a plate fastened on the belt, and fixed, for example, with the id of a lock screw on the toothed disk in the position corresponding to the anatomical parameters of the owner.

The firing device of all modifications has components for holding the projectile, details forming the cavity for discharge of the projectile. In the first modification the cavity has such a shape at which in cross section a figure is formed with a relation of the diameter of the circumference inscribed in it and the length of the line connecting two most removed points of the perimeter making up a value less than 0.8. The other modifications has components forming a cavity, whose axis represents a curved line including at least three lugs the height even of one of them exceeds 0.15 of the diameter of the circumference inscribed in the figure formed on the plane of the cross section of the inner surface of the cavity including even one lug positioned at an angle to the axis of the cavity, its height exceeds 0.15 of the diameter of the circumference inscribed in the figure formed on the plane of the cross section by the inner surface of the plane of the cross section by the inner surface of the plane including even one lug positioned at an angle of not less than 20 deg. to the axis of the plane having a lug of variable width, having non-parallel lugs, having lugs shifted relative to one another along the cavity.

The invention is pertaining to a hand-operated fire small arms and is intended for boosting action of a bullet for a single and automatic fire by standard cartridges, or cartridges with a boosted power, either by silent cartridges, or pulsed jet direct-flow bullets with a standard cartridge, a primer and a powder charge. The aiming device in the pistol is mounted on the mobile barrel for more accurate sighting, at the entry into the cartridge housing there is a deflector, which at a loading excludes a loss or a skew of the cartridge. In the lower part of the cartridge housing the barrel has an elongated bulge, in the middle of which there is a cartridge window for a cartridge passing from the magazine into the barrel housing, and on the end of the bulge there are an ejector and a knock-out tool. Instead of the bulge the barrel may have a plank with a limited motion, the design of which matches to a dilatational bulge for charging a cartridge and discharge of the barrel. The shock-trigger gear with an open trigger ix mounted inside a frame and an under=barrel box, and the trigger - inside a staple, a part of which is spring-loaded. Between the handle and its casing there are return springs for reduction of a recoil force. In the handle a plug-in one-two- box magazine is installed, the upper single-row section of which is placed inside the frame, along which two battle rods of the is shock-trigger gear are passing, and the lower two-row section is intended for increasing the number of cartridges. Changing positions of a two-lever safety catch of a trigger, the toggle of fire, the stoppers of the barrel, the middle safety catch of the hammer, the middle catch of the magazine may be realized by any hand. The invention also differs from its analogs by two methods of a short-time coupling of a mobile barrel with a breech-block, which is constantly connected to a frame since in the barrel cartridge-chamber a cavity (backlash) is formed between a circular outer surface and an inner surface of a cartridge and the barrel cartridge-chamber, which at a shot due to a high-pressure of the powder gases a cartridge wall fills and for a short time joins the barrel and a breech-block. On the side walls of the barrel breech housing there may be symmetrical cross-section flutes, which are coupled with the elastic semi-rings placed in the deep grooves of the breech-block for fixation of the mobile barrel. At a shot, at the high pressure in cohesion of the grooves and the semi-rings the grate friction forces are formed, which hinder compression of the semi-rings and for a short time join the barrel and the breech-block. The invention allows to reduce a recoil force and to increase accuracy of fire.

Proposed firearms includes cartridge retaining units and pat with cavity for escape of filler to be thrown. According to first version, cavity located at distance of 40 mm from entrance has shape at which elementary fragments of its inner surface are located at distance from center of cavity by more than elementary fragments of cartridge retaining surface. According to second version, total length of sections of cavity at said geometry is lesser than total length of sections where fragments of surface are in maximum contact with rubber bullet, i.e. they are located at lesser distance from center of cavity as compared with fragments of cartridge retaining cavity. According to third version, total length of sections of escape cavity whose fragments of surfaces are in maximum interaction with element to be thrown is limited. Minimum length is equal to 0.15 recoil of breech mechanism and maximum length is equal to recoil. Fourth and fifth versions are characterized by availability of holes in walls of escape cavity at distance of 500 from entrance. Holes in fourth version have oblong shape and holes in fifth version occupy area no less than 10% of inner surface of section of cavity.
