Description

The invention relates to personal small-sized weapons of secretive wearing, designed for silent and flameless firing of special cartridges in the conditions of covert attack and defense, as well as for firing ordinary unitary cartridges in combat, police and official use and limited use in civilian traffic, for example, for shooting rubber bullets or gas cartridges for self-defense.

Known personal small-sized weapons designed for silent and flameless firing with special cartridges SP-3, SP-4, etc., for example, SMEs, S-4M "THUNDER", LDCs, PSS, etc. / Ardashev A.N. Fedoseev S.L. Illustrated guide "Special, unusual, exotic weapons." - M .: AST. Astrel. 2001 /.

Weapons designed for firing with special SP-3 rounds are exclusively single-shot or double-shot, since the problem of automatic reloading has not yet been solved with the SP-3 fired cartridge case that increases significantly in length, but for firing with special SP-4 rounds there is a multi-shot self-loading weapon.

Known self-loading pistol PSS for silent and flameless firing with special cartridges SP-4. Since the action of the PSS pistol automatics is based on the principle of using the recoil of a free shutter, the specific noise of the shutter operation during reloading is inevitably superimposed on the sounds of strikes of the striker on the cartridge caps, which is undesirable in the face of a covert attack and defense. In addition, the overall dimensions of weapons of this design during shots vary significantly, which makes problematic shooting in cramped conditions, for example from pockets. In addition, as in other pistol systems, delays in firing are possible, requiring time to eliminate them: sticking a cartridge when it is being fed from the magazine, not ejecting the spent cartridge case and misfiring the cartridge.

The aim of the invention is the creation of fail-safe multi-charge self-cocking weapons of covert carrying and miniature sizes, designed for silent and flameless firing of special cartridges in conditions of covert attack and defense, as well as for firing with conventional unitary cartridges in combat, police and official use and limited use in civilian traffic for firing with rubber bullets or gas cartridges for self-defense, which has increased safety in handling.

SUMMARY OF THE INVENTION To achieve this goal, the shutter function is performed by a barrel-free chamber, which has the ability to move perpendicular to the axis of the barrel and occupy a position along the same axis as the next magazine cartridge. When reloading, the feeder pushes the next cartridge from the magazine into the chamber, displacing the spent sleeve from it through the windows in the rear wall of the gun frame and trigger trigger, and the shutter-chamber with the next cartridge returns to the position along one axis with the barrel. At the same time, the cock is cocked and at the final point of advancement of the shutter-chamber and cocking of the trigger, the trigger is pulled and a shot is fired. Repeated shots can be fired the next time you press the shutter button, which plays the role of a trigger.

The reliability of the weapon is ensured by the fact that the entire operation of the pistol mechanism is based only on the impact of the shooter's finger on the trigger and the impossibility of delays in firing due to the sticking of the cartridge when feeding it to the chamber or because of the removal of the spent sleeve, since the chamber of the chamber is exactly along the same axis as the next cartridge being fed and the fired cartridge case will be forced out by him unconditionally.

When a cartridge misfires, it is pushed out like a fired cartridge case from the chamber by the next cartridge supplied from the magazine with the next pressing the shutter-release button.

Compared to the MSS pistol in the invention, the noise level of the mechanism will be significantly reduced due to the absence of sounds of the free shutter during reloading, which is important in the face of a covert attack and defense.

The overall dimensions of the invention are approximately one third smaller than the prototype comparable in terms of parameters due to the lack of a free shutter, and moving the chamber shutter when reloading perpendicular to the axis of the barrel does not change the dimensions of the weapon during shots and allows shooting in cramped conditions.

Increased safety in the handling of weapons is ensured by the fact that the cartridge enters the shutter-chamber at the moment the trigger is pressed, the rest of the time there is a fired cartridge case.

The invention is illustrated and illustrated by the following drawings. In Fig. 1, a weapon is shown before pressing the trigger, in Fig. 2 is a view of the weapon from the side of the trigger, in Fig. 3 is an SP-4 cartridge with an reinforcing bandage, in Fig. 4 is a PM cartridge with a guide sleeve on the pool, figure 5 shows the weapon at the time of completion of the filing of the cartridge from the store in the shutter chamber and the removal of the shot sleeve PM and the guide sleeve of the bullet from it, figure 6 - weapon immediately before the shot.

The weapon consists of a barrel 1, a casing 2, a shutter-chamber 3, which has the ability to move perpendicular to the axis of the barrel under the influence of the cocking-trigger lever 4 in the grooves 5, frame 6, the release button 7 with a return spring 8, the cartridge feeder 9, acting as a leaf spring , the trigger 10 with the cocking lever 11 on its axis, the leaf spring 12 of the trigger, the retainer of the cartridge 13, magazine 14 with cartridges 15, the latch of the magazine 16, the covers, cheeks 17.

The weapon works as follows. Before equipping the magazine, the barrel of each SP-4 cartridge must be equipped with a reinforcing bandage to prevent destruction during firing, and if unitary cartridges with a cylindrical sleeve without collars, for example PM, are used, the bullet of each cartridge is equipped with a guide sleeve for optimal stability and gas breakthrough. An option would be to equip a pistol with a shutter-chamber with special cartridges with a completely cylindrical sleeve in a silent execution or with a bullet that matches the diameter of the outer diameter unit sleeve thermometer.

In the operation of the mechanism of the pistol with a shutter-chamber, three points must be distinguished. At the initial moment of pressing the trigger with a finger, having a figured groove 18, in which there is an end finger of the cocking-release lever 4, its opposite shoulder moves the shutter-chamber to a position along the same axis as the next cartridge supplied in the magazine. At the end point of the shoulder stroke of the trigger, the spring-loaded dog-hook 19 captures from the inside the cocking lever 11 of the trigger 10.

At the next moment of the release of the release key, its appendage 20 acts on the cartridge feeder 9, the opposite end of which pushes the next cartridge 15 from the magazine 14 into the chamber of the shutter-chamber, displacing the spent sleeve together with the spent guide sleeve 21, if unitary cartridges are used, or a spent sleeve equipped with a reinforcing bandage, if the cartridges SP-4, out through the windows 22 and 23 in the rear wall of the frame 6 and the trigger 10. The spring-loaded latch 13 holds in the shutter-chamber in the required places cartridge.

At the final moment of descent, the cocking-trigger lever 4 moves the shutter-chamber to a position coaxial to the bore, entraining the cocking lever 11 with the dog-hook 19, thereby cocking the trigger pressing on the leaf spring 12. Simultaneously, the shoot 20 of the trigger pulls spring feeder cartridges 9, based on the limit stop 24 of the casing 2, to prevent obstruction of the return stroke of the shutter-chamber and playing the role of an additional return spring. The shoulder of the cocking trigger lever together with the shutter-chamber comes to the end point of its movement, the cocking cocking lever breaks from the dog-hook, the hammer strikes the cartridge capsule with a quick shot, and under the action of the return spring 6 and the spring feeder of the cartridges 9, the trigger key returns to the initial position and the next time you press it, the next shot can be fired, the number of which depends on the caliber of the ammunition used and the capacity of the store.

Note. In figures 1, 2, 5, 6, the weapon is depicted with the right cheek lid removed and in partial section, and in figure 1 the guide sleeve on the next cartridge pool in the magazine is shown in section for clarity.
