Description

The invention relates to weapons technology, automatic small arms systems and can be used in smoothbore guns, in rifled submachine guns and machine guns.

The well-known submachine guns of Sudaev (PPS-42, PPS-43, Shpagina (PPSh-41) [Zhuk AB, Small arms. Revolvers, pistols, rifles, submachine guns, machine guns. - M.: Military Publishing House, 1992. - 735 s. : ill. p. 596-597], which structurally consist of a receiver that is a bearing part, a shutter, a return spring, a trigger, an aiming device, a magazine with cartridges, and the same principle of operation of automation is the return of a free shutter.

The disadvantages of these submachine guns are:

- firing from the rear shutter;

- the presence of the receiver increases the length of the weapon and weight;

- the barrel, bolt and return spring, arranged in series on the same line, increase the length of the weapon, as a result, the barrel length decreases and the tactical and technical characteristics of the weapon deteriorate;

- insufficient accuracy when shooting, since the barrel and butt are not on the same line;

- reliability is lower, since the shutter is located inside the receiver and if foreign bodies get between the shutter and the receiver, it can jam;

- the design does not provide for firing single shots.

Closest to the proposed invention (prototype) is a patent for a utility model "Automatic small arms, MAG-1" [RF Patent for utility model No. 87006, priority 05.02.2009], in which the bearing part is the barrel on which is located an open shutter, fully covering the chamber, the breech of the barrel and the return spring, a handle for holding the weapon is attached to the barrel, in which there is a trigger with an automatic fuse, while the handle is located in the groove of the shutter, the return spring is located wife around the barrel inside the shutter and locks the barrel shutter.

The disadvantage of this design is:

- the return spring of the bolt is located around the barrel, and with intensive shooting the barrel warms up and heats the spring, which loses its elasticity, which ultimately renders the weapon unusable;

- in the trigger mechanism is not provided for firing single shots;

- shooting is carried out from the rear shutter and at the same time the aiming at the target is lost when firing.

The technical result when using the present invention is to increase the accuracy of hitting, reducing the size and weight, increasing the reliability of weapons due to:

- excluded overheating of the return spring, as it is located above the shutter;

- it is possible to fire both single shots and bursts with greater accuracy due to the use of the trigger mechanism;

- increased rigidity due to the installation of the shutter, in the cross section of which a rectangle;

- it is designed for people of right-handed and left-handed people, since the handle for jerking the shutter is located on top of the shutter, the automatic fuse button in the back of the handle is automatically activated by the palm of the hand;

- simplicity of design and manufacturability of weapons.

The technical result is achieved by the fact that the shutter is made in the form of a hollow rectangle with a longitudinal groove at the bottom, the return spring is located above the shutter in the protective casing, and the trigger mechanism is located on the clutch guides between the magazine and the shoulder rest and is located inside the shutter.

Figure 1 shows the barrel 1. In the muzzle of the barrel 1 mounted front sight 2. On the lower plane of the breech of the barrel and the chamber, made in the form of a rectangle, the edges of which are guides for the shutter, fixed base 3, designed to mount the handle for holding on which will be the trigger and the key to remove the fuse. In the breech of the barrel there is an aiming device (rear) 4. A thread 5 is cut on the chamber to connect the barrel 1 to the sleeve 6. The sleeve 6 in cross section is a rectangle and has two guides 7, between which a magazine with cartridges is installed, as well as a trigger mechanism and at the end of the rails, a removable shoulder rest 8 and a shock absorber 9 are attached.

Figure 2 shows the barrel 1, the base of the handle 3, the coupling 6 with the guides 7.

Figure 3 shows the connection of the barrel 1 with the sleeve 6 with the guides 7, having in the lower part of the groove 10 for attaching the lower cover, the base of the handle 3 is shown on the barrel, and the shutter 11 is also shown.

Figure 4 shows the installation on the barrel 1 of the shutter 11, a handle for jerking the shutter 12. Between the barrel 1 and the shutter 11 a return spring 13 is mounted, mounted on the rod 14. The front sight 2, the rear sight 4, the shoulder rest 8, the guides 7 are shown.

Figure 5 shows a section of the handle 15, in which the fuse button and the trigger is located, and which is mounted on the base 3.

Inside the handle 15, there is a fuse key 16 on the axis 17, the trigger 18. The handle includes a rod 19, which is connected to the trigger 18 and located under the shutter 11. An elbow 20 is shown having an axis of rotation 21 with a spring 22. The principle of installation and fixing is shown magazine 23, the lever 24 for fixing the magazine 23 is installed on the bottom cover 25.

Figure 6 shows a section of an automatic small arms - "MAG-3", which shows the barrel 1, front sight 2, rear sight 4, shoulder rest 8, shock absorber 9, shutter 11, magazine 23, a handle for holding 26, which holds the weapon and helps stabilize the weapon during firing, and also allows the arm to be located at a distance from the barrel heating up during firing, cover 27 for protecting the return spring 13 from foreign bodies, trigger mechanism 28.

7 shows a cover 27 for protecting the return spring and a lower cover 25.

On Fig 8 is a General view of the automatic small arms, which shows: barrel 1, front sight 2, rear 4, shoulder rest 8, shutter 11, handle for jerking the shutter 12, handle for holding 15, trigger 18, magazine 23, cover for protection return spring 27.

We take the weapon in our hands by the handles 15 and 26 and insert the magazine 23 with cartridges, which is fixed by the lever 24. For the handle 12, we twist the shutter 11 into the rear extreme position, while the return spring 13 is compressed, and the trigger is cocked in the trigger mechanism 28. When releasing the handle 12 from the action of the return spring 13, the shutter 11 along the guides of the barrel 1, the clutch 6 and the guide plates 7 moves to the front position, while the shutter removes the cartridge from the magazine 23 and sends it to the chamber.

We take the handle 15, while the key 16 is rotated on the axis 17, enters the handle 15, compresses the spring 22, cranks the knee 20 on the axis 21 and releases the rod 19 connecting the trigger 18 with the trigger mechanism 28, while removing the weapon from fuse. When the movement is reported to trigger 18 on ½ of the way, a single shot occurs, with its further movement to the stop, automatic firing occurs.

When firing automatic fire, the trigger mechanism 28 is configured so that the destruction of the capsule occurs earlier by 2-3 mm before the shutter 11 takes its extreme forward position. As a result, the kinetic energy of the forward-moving shutter will be absorbed by the recoil during firing, the shutter will stop and then, due to the pressure of the powder gases, it will begin to roll back to its extreme rear position until it stops due to the shock absorber 9.

When moving backward, the bolt 11 compresses the return spring 13, throws the spent sleeve into the bolt window and in the trigger mechanism 28, the bolt puts the trigger on the cocking.

In the extreme rear position, the shutter 11 abuts against the shock absorber 9 mounted on the shoulder rest 8, gives its kinetic energy to the shock absorber 9 and stops, and then, under the influence of the return spring 13, starts to move forward, removes the cartridge from the magazine 23 and sends it to the chamber.
