Description

 The invention relates to small arms.

 Known submachine gun "Cedar" containing a receiver with a barrel, bolt, receiver cover, return mechanism, trigger mechanism, butt (see Encyclopedia of modern weapons and armored vehicles, t.2, p.317, 318, ed. Polygon ACT, 1997, St. Petersburg).

The disadvantages of the submachine gun "Cedar" are:
- when firing from this submachine gun, only the 9x18 PM cartridge is used. For firing of high-power cartridges 9x18 PMM, it is necessary to modify the barrel chamber (spiral grooves) to reduce the speed of moving parts;
- lack of reliability of the trigger mechanism of the submachine gun, which uses the tipping of the trigger dead center.

 The closest in technical essence and the achieved result to the claimed invention is a 5.45 mm Kalashnikov assault rifle shortened AKS74U (see V.I. Murakhovsky, S.L. Fedoseev. Infantry weapons. P.184, published by Arsenal-press, 1992 ., Moscow), containing a barrel connected by a pin to the receiver, a frame with a handle, a bolt, a trigger mechanism with a translator, a return mechanism, an aiming device, a butt, a magazine latch located in the receiver for installing the magazine.

The disadvantages of the machine AKS74U are:
- use for shooting a powerful cartridge, unsafe when used in urban environments;
- the complexity of the device engine automation;
- the complexity of the device for fixing the butt in the stowed position.

 The objective of the proposed invention is the creation of a submachine gun, providing a technical result, which consists in increasing the reliability of operation, improving operating conditions and improving manufacturability.

 This technical result in a submachine gun containing a barrel connected via a pin to the receiver, a frame with a handle, a bolt, a trigger mechanism with a translator, a return mechanism, an aiming device, a butt, a magazine latch located in the receiver, is achieved by that the frame and the shutter are made as a single unit in the form of a single shutter part, on which inclined platforms are made that interact with the sleeve when reflected, a bevel is made on the shutter handle with the possibility of interaction with revodchikom, the stem pin is formed with a protruding head at the end of which formed a cone and the annular groove, locking the butt in the receiver recess is formed on the receiver width for installation therein store.

 The submachine gun is equipped with an adapter, which is installed in the cutout of the receiver.

 The sighting device is equipped with an aiming pad made with a dividing protrusion, while in the sighting pad there is an aiming bar made with two successive distance scales. The distance scales are made on two types of cartridges with different initial bullet speeds.

The invention is illustrated by drawings, where figure 1 shows a General view of the submachine gun with auger magazine; figure 2 is a General view of the submachine gun with a box magazine; figure 3 - aa in figure 1; figure 4 is a front view of the frame; figure 5 - BB in figure 4; figure 6 - In figure 2; in FIG. 7 - D in figure 2;
In FIG. 8 - D in FIG. 7; Fig.9 is a bottom view of the receiver (the store is not shown).

 The submachine gun contains a receiver 1 with a barrel 2, interconnected by a pin 3, butt 4, receiver cover 5, receiver 6, front sight 7. In the guides of the receiver 1 there is a shutter 8 with inclined platforms 9, 10 on the upper protrusion and inclined platforms 11, 12 on the side surface. The bevel 13 is made on the handle 14 of the shutter 8. In the receiver 1 there is a return mechanism 15, a trigger mechanism consisting of a trigger 16, a self-timer 17, a trigger 18, whispered 19. In the lower part of the receiver 1 there is a fire control handle 20, safety bracket 21 with latch 22 magazine. An interpreter 23 is located on the wall of the receiver 1. On the receiver 1 there is an aiming block 24, on which a dividing protrusion 25 is made. An aiming plate 26 is placed in the aiming block 24, having two successive distance scales 27 and 28.

 In the receiver 1, a cutout 29 is made in which a screw magazine 30 can be installed using the magazine latch 22 and magazine pin 31 or an adapter 32 using magazine magazine latch 22 and magazine pin 31 in the case of a box magazine 33.

 A protruding head 34 with a cone 35 and an annular groove 36 is made on the pin 3 of the barrel 2.

 In the shutter 8 there is a socket 37 for accommodating the bottom of the sleeve, a cylindrical channel 38 for accommodating the striker 39 and a longitudinal groove 40 in which the ejector 42 is located on the axis 41.

 To load the submachine gun, it is necessary to install the magazine 30 in the cutout 29 of the receiver 1 using the magazine latch 22 and the magazine pin 31 or the magazine 33 in the adapter 32 installed in the notch 29 of the receiver using the magazine latch 22 and the magazine pin 31, transfer the butt 4 in the combat position, removing it from the annular groove 36 on the pin 3 of the barrel, put the translator 23 in the firing position (automatic or single), put the clamp of the aiming plate 26 at the required distance of the scale 27 or 28, corresponding to the applied to the cartridge. Then it is necessary to take the shutter 8 to its extreme rear position, while the spring of the return mechanism 15 is compressed, and release the shutter. The shutter 8 under the action of the spring moves to its extreme forward position, sending the cartridge from the magazine 30 or 33 to the barrel 2. The submachine gun is ready to fire.

 To fire a shot, press the trigger 18. In this case, the trigger 16 hits the hammer 39, which breaks the cartridge capsule. A shot is taking place.

 After the shot, the shutter 8, rolling into the rear position, removes and reflects the sleeve, cocks the trigger 16 and compresses the spring of the return mechanism 15. The sleeve, interacting with the inclined platforms 9, 10, 11 and 12 of the shutter 8, is displayed in the extraction window of the cover 5 of the receiver 1 . In the forward position, the shutter 8 is returned by the spring of the return mechanism 15, sending another cartridge from the magazine 30 or 33 into the barrel. After the shooting, the translator 23 is set to the upper position, while it stands opposite the bevel 13 of the handle 14 of the shutter 8. In the case of a falling submachine gun on the butt 4, the bevel handle 13 presses the translator 23 against the receiver 1, preventing bending and breakage of the translator 23.

 When folding the butt 4 in the stowed position, its upper rod slides along the cone 35 of the pin 3 and pops into the annular groove 36, fixing the butt.

 Thus, the proposed design of the submachine gun provides increased reliability, improved operating conditions and increased manufacturability.
