Description

The group of inventions relates to the field of armaments, in particular, to small arms with magazine supply of cartridges and can be used in automatic small arms.

The 5.45 mm Kalashnikov AK-12 assault rifle is known (https://kalashnikov.media/video/weapons/kak-ustroen-avtomat-ak-12, the 5.45 mm AK-12 Kalashnikov assault rifle Operating Instructions 6P70.RE), comprising a barrel with a receiver, a bolt frame with a bolt, a magazine including a housing, a lid, a locking bar, a magazine spring, a feeder. When the cartridges are used up in the magazine, the moving parts are in the front position. To load the magazine, it is necessary to put the translator on the fuse, disconnect the empty magazine, attach the equipped magazine, put the translator on the selected shooting mode, pull the shutter frame with the shutter back to the stop and release. The weapon is ready to fire.

The disadvantage of this sample is the cost of significant time for reloading and firing.

The technical task of the group of inventions is to reduce the readiness for firing of small arms with store feed.

The technical result consists in the possibility of replacing an empty magazine with a full magazine when the moving parts are in an intermediate position.

The task in the first solution is achieved by the fact that the small arms with a magazine feed contains a receiver in which movable parts are located, including a bolt frame with a bolt, and a magazine is installed containing a magazine case, feeder, spring. On the back wall of the feeder, an emphasis is made with the possibility of interaction with the shutter when the cartridges are used up in the magazine.

In the second variant of the solution, the task is achieved in that the small arms with a magazine feed contains a receiver in which moving parts are located, including a shutter frame with a shutter, a shutter delay mechanism that includes a shutter stop, and a magazine containing a magazine case, a feeder, a spring is installed . On the back wall of the feeder, an emphasis is made with the possibility of interaction with the shutter stop when the cartridges are used up in the magazine.

The invention is illustrated by drawings, which depict:

in FIG. 1 - general view of the weapon (moving parts are stopped by the focus of the feeder);

in FIG. 2 - general view of the weapon (stop included, moving parts stopped by shutter stop).

in FIG. 3 - general view of the store;

in FIG. 4 - general view of the feeder.

Small arms contains a magazine 1, consisting of a housing 2, a magazine cover 3, a locking bar 4, a magazine spring 5 and a feeder 6 (Fig. 3).

Inside the case 2 of the magazine there is a feeder 6, a spring 5 of the magazine, a locking bar 4. The feeder 6 has a protrusion 7, which provides a staggered arrangement of cartridges in the magazine, as well as an emphasis 8 made on the rear wall of the feeder 6 (Fig. 4). The stop 8 can be made of any shape, for example, a rectangular shape (Fig. 2). Inside the housing 2 on the rear wall there is an internal groove 9, along which the emphasis 8 of the feeder moves.

The locking plate 4 is installed on the lower end of the spring 5 of the store and its protrusion 10 keeps the cover 3 of the store from moving.

Shop 1 is installed in the window of the receiver 11. In the receiver 11 are movable parts 12, including the shutter frame 13 with the shutter 14.

In the first embodiment, when the last cartridge from the magazine 1 is fed to the dispatch line, the feeder 6 comes to the upper position, and the movable parts 12 are stopped by the emphasis 8 of the feeder 6. The movable parts 12 are in an intermediate position, showing that the cartridges have run out of cartridges (Fig. 1 )

In the second embodiment, the moving parts 12 comprise a shutter delay mechanism 15, including a shutter stop 16. When applying the last cartridge from the magazine 1 to the sending line, the feeder 6 comes to the upper position, and the stop 8 of the feeder 6 interacts with the shutter stop tooth 17 17, raising the shutter stop 16 to the moving line of the moving parts 12, stopping the moving parts 12. The moving parts 12 are in an intermediate position, showing that the magazine 1 ran out of cartridges (Fig. 2).

Before firing, it is necessary to attach an equipped magazine 1 to the weapon, for the reload handle (not shown), the bolt frame 13 with shutter 14 vigorously pull back to the stop and release, the bolt frame 13 with shutter 14 will return to the front position. The work of moving parts and mechanisms of small arms is carried out depending on the selected shooting mode (automatic shooting, etc.).

According to the first option, when the cartridges in magazine 1 are used up, the feeder 6 will rise to its highest position, and the bolt frame 13 with the shutter 14 will stop with the focus 8 of the feeder 6. For further work, holding the movable parts 12 with the reload handle, disconnect the magazine 1. Attach the equipped magazine 1, without reloading weapons. The weapon is ready to fire.

According to the second option, when the cartridges are used up in magazine 1, the feeder 6 rises to its highest position and with its stop 8 raises the shutter stop 16, the shutter frame 13 with the shutter 14 stops while moving forward, being held by the shutter stop 16. For further work, it is necessary to disconnect the magazine 1 by pressing the magazine latch lever (not shown). Attach the equipped magazine 1, press a key (not shown), stop 16 of the shutter will disengage from the shutter 14. The weapon is ready to fire.

Thus, the proposed design can reduce the time of readiness for firing from small arms.
