Description

The present invention relates to the field of small arms, namely to pistols, providing the possibility of firing cartridges with rubber (elastic) bullets of traumatic action, and is intended for use mainly as a weapon of self-defense.

Currently, the world is widely developed means of active individual protection of citizens from attack. One of the types of active defense protective equipment includes pistols chambered for traumatic action, firing rubber bullets that have enough energy to exert only a certain traumatic, but not fatal, effect on the attacker (D. Kochetkov. Traumatic weapon market: model overview, www. arsenalnov.ru).

Typically, such pistols are created by finalizing the design of existing combat pistols for a new, less powerful in relation to combat, traumatic cartridge with a rubber bullet (see, for example, patents for a utility model of the Russian Federation No. 65199, 2007; 65636, 2007; patent for the invention of the Russian Federation No. 2325610, 2007, etc.).

The design of the domestic self-loading pistol for the traumatic cartridge "Leader-TT" (www.sniper-m.ru/news20060606.php), based on the Tokarev pistol (TT), which was previously armed with the army, is known.

The gun was upgraded to a new 10 mm cartridge with two rubber bullets that have an effective effect on the attacker. The gun is equipped with a fixed barrel simulator. The gun is large enough, the magazine capacity is 8-10 rounds (patent for utility model of the Russian Federation No. 65199, 2007).

The disadvantage of this gun is overestimated weight and size characteristics, limited operating life, the relatively complicated design of the slide delay, and its refinement to the gun under the traumatic cartridge is long and expensive (see utility model of the Russian Federation No. 72752, 2008).

Known gun chambered for traumatic action T10 firm Grand Power, presented in the application PCT SK 00/00021 (03.10.2000), publ. WO 01/51871 (07/19/2001), Russian Federation application 2002121164/02 (03.10.2000). The pistol was created on the basis of the combat K100 to provide the possibility of firing traumatic cartridges.

The gun contains a plastic frame (case), in which a bolt that is movable during firing, a barrel fixedly mounted on the frame, a trigger mechanism with a return spring and a fuse, a two-row magazine for 17 rounds of 10 × 22T caliber are mounted on a steel insert.

The T10 pistol has high firing accuracy, durability, comfortable recoil.

However, when shooting from this pistol with traumatic cartridges, a large percentage of delays in the operation of the automatics was revealed due to sticking and distortions when feeding cartridges into the barrel.

Known semi-automatic pistol, made according to the classical Browning scheme, using the recoil energy for reloading weapons, the Austrian company Styer Mannlicher Gmbh (its American branch "Styer Arms, inc" produces the same-name pistols (www.gewehr.ru)). This gun, taken as a prototype of the proposed one, contains a housing in which all the elements of the gun are located: a movable barrel with a chamber, a kinematically connected reciprocating sliding shutter, a cartridge feeding device for the chamber and extraction, a trigger mechanism, and return systems shutter and lock the barrel, the store in the handle. The barrel locking system includes a locking stop on the upper inner surface of the shutter, protrusions in the breech of the barrel: a control protrusion on its outer upper surface, front and rear protrusions restricting the movement of the barrel, made on its outer lower surface and in contact with beveled supporting surfaces with restrictive stops, fixed in the case. The shutter return system includes a return spring mounted on the guide rod.

The well-known gun is reliable, has great operational strength, modern design, compact.

The disadvantage of this pistol is the impossibility of using it as a civilian weapon, namely as a pistol with the possibility of firing traumatic ammunition with a rubber bullet.

The task to which the technical solution is directed is to expand the arsenal of non-lethal active defense means, namely the creation of a pistol under a traumatic action cartridge, using cartridges with throwable equipment from elastic material, such as rubber, which immobilizes the offender, but does not cause him death.

The technical result of the claimed is to ensure reliable operation of the pistol automatic when firing a rubber bullet, reducing the likelihood of delays when feeding a cartridge into the barrel by maintaining the barrel’s mobility relative to the body, the algorithm of the movement of all moving parts and maintaining the cartridge supply path, as well as simplifying the adaptation of the combat pistol to the self-defense gun .

The specified technical result is achieved by the fact that the gun contains a housing in which the barrel with a chamber is movably placed, a reciprocating sliding shutter kinematically associated with it, a cartridge feeding device into the chamber and extraction, a shutter return system, a barrel locking system including a stop on the upper inner shutter surfaces, protrusions in the breech of the barrel: control - on the outer upper surface, front and rear, restricting the movement of the barrel, made on its outer lower turn and contacting the beveled supporting surfaces with the corresponding surfaces of the restrictive and installation stops of the body, in which, according to the proposal, the barrel is self-braking with the possibility of adjustable axial braking by means of a support, inclined to the muzzle hole, made along the upper outer surface of the barrel control protrusion, in the form of a cut .

The gun is characterized in that the supporting platform, inclined to the muzzle hole on the control protrusion of the barrel in the form of a slice, is made at an angle of 4-83 ° to the axis of the barrel.

The gun is characterized in that the beveled supporting surfaces of the projections of the barrel on its outer lower surface and the mounting stop, restricting the movement of the barrel, are made at an angle of 10-80 ° to the vertical.

The specified indicated values of the angles of inclination of the surface of the support platform and the beveled surfaces of the projections of the barrel and the mounting stop of the body are obtained experimentally and are optimal.

According to the applicant, the above signs are significant, because, despite the well-known implementation of the barrel locking system in the form of kinematically interacting protrusions and control and restrictive stops, made in various ways in the shutter, barrel and body, the proposed invention is a solution to the design problem, which allowed to change the main the function of the control protrusion of the barrel - locking - on the function of reducing the speed of movement - braking - and take the barrel back, which ensures optimal cartridge feed path; the approach of the axis of the barrel channel to the handle made in the housing, which reduces the tipping moment acting on the gun during firing, ensures the operation of the gun automation, eliminating delays in use (sticking, skew cartridge), guaranteeing reliability and safety of the gun.

In addition to the above, the proposed design allows for the affordable refinement of a combat pistol for a traumatic one using rubber bullets; the modernization technology is simple, provides reduced costs for the manufacture of both a pistol and interchangeable barrels for combat pistols, that is, to expand the scope of their application.

Figure 1 shows a General view of the gun under the cartridge traumatic action, a longitudinal section (the shutter is in the front position); figure 2 is the same, the shutter in the rear position; figure 3 - node I (figure 1), the shutter and the barrel in the locked position; figure 4 - (node II) the shutter and the barrel is in position when fired.

A pistol for a traumatic action cartridge contains a housing 1, which is the main fixed part of the pistol and in which all its components and parts are located: movably — the barrel 2 with a chamber, a kinematically connected reciprocating sliding bolt 3, a cartridge feeding device 4 into the chamber and extraction, shutter return system 5, barrel locking system 6, magazine 7 in the handle. The shutter return system 5 includes a return spring mounted on a guide rod. The barrel locking system 6 includes an abutment 8, in the form of a front edge of a sleeve ejection window, on the upper inner surface of the shutter and protrusions in the breech of the barrel: a control protrusion 9 on the outer upper surface of the barrel 2, front and rear protrusions 10, 11 (respectively), restricting the movement of the barrel 2, made on its outer lower surface and in contact with the beveled supporting surfaces 12, 13 with the corresponding surfaces of the limit stop 14 and the mounting stop 15, mounted in the housing 1. By means of the protruding pov 10, 11 the barrel is planted on the mounting stop 15, fixed rigidly in the housing under the barrel and providing the ability to move the barrel at the time of the shot on a straight horizontal initial section and bounded at an angle to the vertical down.

The operation of the pistol is provided by the trigger mechanism 16.

The barrel 2 is made self-braking with the possibility of adjustable axial braking by means of a support platform 17 inclined towards the muzzle opening, interacting with a stop 8 and made along the upper outer surface of the control protrusion 9 of the barrel 2 in the form of a cut. Inclined platform 17 - the slice is made at an angle of 4-83 ° to the axis of the barrel 2. If there is an inclined platform on the trunk, the beveled supporting surfaces 12, 13 of the protrusions 10, 11 and the stop 15 are expediently made at an angle of 10-80 ° to the vertical.

The interaction of parts and assemblies of the proposed pistol during firing does not differ from the prototype and in it, as in any pistol that uses the principle of a free shutter, the latter is rolled back when fired by the pressure of the powder gases, the fired sleeve is thrown out, the trigger mechanism is cocked , and on the coast, the bolt captures a new cartridge, sends it to the chamber, and when you press the trigger again, the cycle repeats.

Before the shot, the bolt 3 with the barrel 2 under the action of the return spring of the system 5 is in its extreme forward position. At the time of the shot from the pressure of the powder gases at the bottom of the sleeve, the shutter 3 is thrown back. The barrel 2, carried away by the shutter, also begins to move backward, and the barrel in the rear (breech) is lowered downward at an angle to its longitudinal axis, having a rectilinear section of movement limited by the protrusions 10, 11. The shutter from the very beginning of the movement begins to move away from the reference platform 17, the shutter and the trunk are released. The movement of the barrel stops. The shutter, continuing the rollback, compresses the return spring, throws the sleeve, reaches the extreme rear position. With the reverse stroke, the shutter sends another cartridge into the chamber of the barrel 2 and moves it to the front position. The gun is reloaded and when you press the trigger, the cycle repeats.

Such a design was tested and tested at the test site.

787 shots were made with traumatic ammunition cartridges with a rubber bullet from pistols: “Leader” (manufactured by the Vyatka-Polyansky Molot Machine-Building Plant); T10 ("Grand Power"); from a pistol "Steyr M-A1", equipped with a set of interchangeable barrels of the proposed design. Each of the set of interchangeable shafts had a protrusion 9 with a support platform 17, made in the form of a slice inclined to the axis of the barrel at an angle (from 0 ° to 90 °). The angle interval was 3 °; the bevels of the supporting surfaces of the protrusions 10, 11 and the stop 15 of the proposed design ranged from 10 ° to 80 ° with an interval of 5 °.

The tests were carried out at an ambient temperature of + 1 ° - + 20 ° C.

Tests showed:

- when performing the reference inclined platform 17 of the protrusion 9 under the fragile 0-10 ° there is no movement of the barrel down;

- when performing the reference inclined platform 17 of the protrusion 9 under the angle of 80-90 ° there is a rigid locking of the barrel with a shutter; automation does not work;

- the implementation of the beveled surfaces 12, 13 of the protrusions 10, 11 of the barrel and the stop 15 with the indicated angles provides the required movement of the barrel.

During the experimental firing, there were no delays, the shutter left the gate for missing cartridges, they were poked at the angles of inclination of the platform 17 4-83 °, the inclination of the beveled surfaces 12, 13 of the protrusions 10, 11 and the stop 15 - 10-50 °.

Optimum angles are established that provide the required movement of the barrel with braking, reliable operation of automation, high stopping and traumatic effect: the angle of inclination of the platform is 14-20 ° to the axis of the barrel; bevel angle of surfaces - 30-50 ° to the vertical.

At present, a prototype pistol for a traumatic cartridge is manufactured and tested at the enterprise. Tests have shown that the sample meets the necessary certification requirements, the cost of modernization is low. The design has enhanced functionality: as a civilian weapon of self-defense and, in the presence of interchangeable barrels for combat pistols, as a weapon of law enforcement agencies.

Preparations are underway for certification of the gun described above.
