Description

The invention relates to stores of small arms, namely, box-shaped stores with feeder cartridges.

Known box store with a feeder cartridges, which is equipped with an adapter installed at the front inner wall of the store. The store can be equipped with two types of cartridges: standard cartridges with a bullet protruding from the cartridge case, and, with the adapter installed, shorter shot cartridges (US Patent No. 2,840,944 according to IPC 9 F41A 9/71 patented July 1, 1958).

Known box store with a feeder cartridges, which can be equipped with cartridges of various lengths. In it, in the inner cavity of the store, a stand is fixed that can be rotated and fixed in the selected position, the rack in contact with the nose of the bullet of the cartridge loaded into the magazine (US Patent No. 2,895,248 according to IPC 9 F41A 9/71 patented July 21, 1959).

The disadvantages of these analogues is the need to carry out the readjustment of the store, when replacing the type of equipped cartridges, which requires a certain time and conditions for its implementation.

Known box store, which is used to place cartridges and feed them into the receiver. It consists of a housing, a cover with a retaining plate, a spring and a cartridge feeder. The sides of the store’s case have bends to keep the cartridges from falling out, there is a hook on the front wall and a support ledge on the back, through which the store is attached to the receiver. Inside the housing there is a cartridge feeder with a spring. There is a protrusion on the feeder that provides a staggered arrangement of cartridges in the store (Manual on small arms. 7.62 mm modernized Kalashnikov assault rifle, M .: Military publishing house. 1985, p. 152 - prototype).

The disadvantage of the prototype is that the store is designed to accommodate only one type of ammunition, which narrows the operational characteristics of the weapon.

The objective of the invention is to develop a magazine design for placing cartridges of various lengths, in which when replacing the type of cartridges currently being equipped, the magazine does not need to be re-set, which increases the operational characteristics of the weapon.

According to the invention, the solution to this problem is achieved by the fact that in a small arms store containing a box-shaped case with bends in the upper part for holding cartridges, a cartridge feeder with a protrusion on the upper surface, a spring, a cover and cartridges arranged in two rows in a checkerboard pattern are implemented following technical solutions:

- along the longitudinal axis of symmetry of the magazine case in the front and rear walls along the entire height of the magazine, grooves are made in which the live part of the bullet and the flange of the cartridge case with a long bullet equipped in the magazine are respectively placed;

- in the middle part of the protrusion on the cartridge feeder there is a transverse groove in which a spring-loaded slider is installed with the possibility of moving along the groove and interacting with the cartridge, the side surface of which facing the cartridge is beveled at an acute angle;

- the upper surface of the engine, as well as the part of the cartridge feeder located in the recess in the rear of the magazine, are flush with the protrusion on the upper surface of the cartridge feeder;

- in an unloaded magazine and a magazine equipped with cartridges with a long bullet, the engine is shifted laterally beyond the longitudinal axis of symmetry of the magazine body.

The essence of the invention is illustrated by graphic materials, where:

- figure 1 shows a longitudinal section along the body of the store, equipped with cartridges in a checkerboard pattern;

- figure 2 shows a cross-section of the magazine on the engine, placed in a transverse groove in the protrusion of the feeder;

- figure 3 shows a top view with a partial cut along the side wall of the store;

- figure 4 shows a longitudinal section of a magazine equipped with cartridges with a long bullet;

figure 5 shows a cross-section of the magazine on the engine, placed in a transverse groove in the protrusion of the feeder - the engine is shifted in the transverse direction beyond the longitudinal axis of symmetry of the store;

- figure 6 shows a top view with a partial section along the side wall of the store.

Small arms store contains a box-shaped case 1 with bends 2 in the upper part for holding cartridges. Inside the store placed spring-loaded 3 feeder cartridges 4 with a protrusion on the upper surface 5 and cartridges 6, arranged in two rows in a checkerboard pattern. From the bottom of the magazine is closed by a cover 7. In the middle part of the protrusion on the cartridge feeder there is a transverse groove 8, in which a spring-loaded 9 engine 10 is mounted with the possibility to move along the groove and interact with the cartridge. The side surface of the engine 11 facing the cartridge is beveled at an acute angle . On the longitudinal axis of symmetry of the magazine case in the front and rear walls along the entire height of the magazine, recesses 12 and 13 are made, in which respectively the animated part of the bullet 14 and the flange of the sleeve 15 of the cartridge with a long bullet 16. The upper surface of the engine 17, as well as part of the cartridge feeder, located at the rear of the magazine, flush with a protrusion on the upper surface of the cartridge feeder. In an unloaded magazine and magazine equipped with cartridges with a long bullet, the engine 10 under the action of the spring 9 is displaced in the transverse direction along the groove beyond the longitudinal axis of symmetry of the magazine body. A hook 18 is made on the front wall of the magazine from the outside, and a support ledge 19 is made on the rear wall, through which the magazine is attached to the weapon receiver.

Before the magazine is equipped with a cartridge feeder 4 under the action of the spring 3 is in its highest position, the engine 10 under the action of the spring 9 is displaced in the transverse direction beyond the longitudinal axis of symmetry of the magazine case.

When the magazine is equipped with cartridges 6, the latter is started under the hooks 2 of the magazine and shifted back and to the side wall of the magazine is laid on the lower surface of the feeder. The first cartridge with its lateral surface, acting on the bevel 11 of the engine 10, biases the engine towards the side wall of the magazine, pressing the spring 9. The subsequent cartridges are staggered until the magazine is completely filled. When the magazine is equipped with cartridges 16 with a long bullet, it starts up under the hooks 2 of the magazine and moves back, while the animated part of the bullet 14 and the flange of the sleeve 15 are located in the recesses 12 and 13, made in the front and rear walls of the magazine, respectively. The sleeve of the lower cartridge rests on the protruding part of the cartridge feeder located in the recess of the magazine 13, and on the upper surface of the engine 17.

The proposed design of the store is verified with positive results on a prototype sniper rifle. Technical solutions inherent in the design of the store, eliminated the need for readjustment of the store during the transition from one type of cartridges to another.
