Description

The utility model relates to firearms, namely to box magazines located in the handle of a gun.

A well-known gun (Patent RU No. 2079086, IPC F41C 3/00, F41A 9/61, published 05/10/1997), to increase the reliability of the store and sending the cartridge into the chamber, to improve the operating conditions of the gun on the inner side surfaces of its frame are spring longitudinal guides, one end of which is rigidly fixed to the frame, and the curved part of them is directed inside the frame, forming a narrowing, and is located between the barrel and the bends of the store. A swinging two-arm lever is installed on the feeder of the store on the axis, the small shoulder of which is directed towards the front wall of the store. The distance from the front wall of the store to the center of the swing axis of the lever is less than the distance from the front wall of the store to the bends of the store.

The main disadvantage of such a gun is that it provides for the use of only a special cartridge of stopping action of a fixed caliber, equipped with a non-metal bullet in the form of a ball of rather considerable size with a diameter of 16.5 mm and a small powder charge.

In the well-known designs of stores located in the handle of the weapon, to ensure guaranteed pressing of the supplied cartridge (cartridge with a protruding edge) to the bends of the case of the store, the following types of feeders are used:

- a floating feeder, the change in the position of the feeding platform in which is provided by bevels on the protrusion entering the store’s spring, for example, Walter R1 of Germany, automatic pistol NKMR5 A2 (Schutzenwaffen heute (1945-1985). DDR, Berlin, 1990, pr. . 1, p. 126, 140);

- a feeder with forced preloading of its front part, where the guaranteed compression of the cartridges is ensured by the action of a coil of spring on the lower ledge in the front part of the feeder, for example, a Swiss gun model SiG-Squer Ρ 200 and Ρ 225 (Schutzenwaffen heute (1945-1985). DDR, Berlin , 1990, book 1, p. 370) ";

- a swinging feeder, the magazine spring is in contact with the feeder in the center of the platform, for example, a Berhardt-Luger automatic pistol, (A. A. Blagonravova et al. “Material of automatic small arms”, part 1, Military Commissariat of the People’s Defense of the USSR, Moscow, 1940 c. p. 74.).

The well-known special-purpose pistol OTs-27 "Berdysh", developed by I.Ya. Stechkin, the main feature of which is that it is equipped with interchangeable barrels for various caliber cartridges. The gun is available in three versions, allowing the use of four varieties of cartridges - 9 × 18 PM and PMM, 9 mm 9 × 19 Parabellum and a cartridge of 7.62 mm 7.62 × 25 TT. Replacing the barrel and magazine allows you to use all of the listed cartridges (7.62 × 25 mm TT, 9 × 18 mm PM, 9 × 18 mm PMM, 9 × 19 mm Parabellum) in one sample (Small arms of Russia / F.K. Babak; edited by L.E. Golod. - M .: ACT; St. Petersburg: Polygon, 2005, pp. 83-84., As well as Revolvers and pistols: Encyclopedia of modern handguns / A.B. Zhuk. - M .: Onyx Publishing House LLC; Mir and Education Publishing House LLC, 2006, pp. 316-317).

The disadvantage of this design is the need to have different stores for different types of cartridges.

An analysis of the pistol cartridges used in pistols with their supply from the magazine located in the handle showed that all of them are mainly made with a protruding edge, which simplifies the supply and retraction of the cartridge into the chamber, and their bullets protrude relative to the cartridge case and have a pointed conical-spherical form. Examples of pistols are: Browning automatic pistol, Colt automatic pistol, BORHARDT-Luger automatic pistol, Mauser automatic pistol, Tokarev automatic pistol and others. The description of which is reflected in the Material of Automatic Small Arms, 4.1, Military Commissariat of the USSR Defense Commissariat, Moscow, 1940 respectively ss. 53, 61, 68, 76.

One of the problems of developing a pistol with the possibility of using interchangeable barrels for the use of various 9 mm cartridges: 9 × 18, 9 × 19 or 9 × 21 is the development of a magazine for each type of cartridge to ensure reliable supply of cartridges with a conical-spherical nose design that meets the standard in the form of a small arms bullet with a protruding rim located in the handle of the gun, followed by chambering the cartridge into the chamber.

All of the above analogs have cartridge magazines that use cartridges with a protruding rim, located in the handle, while a magazine is developed for each cartridge. In them, the guaranteed preload of the cartridges is provided by changing the position of the feeder in direct contact with the spring.

This does not eliminate the possible jamming of cartridges when moving them up to the flaps of the store, which can lead to a delay when firing in the form of a cartridge pass or sticking it.

A well-known small arms store (Patent SU No. 436221, IPC F41A 9/61, F41C 7/00, published 20.12.1999)., Containing a box-shaped housing, lever feeder, feeder spring and cover, with execution in the upper part of the rear wall of the store body longitudinal cutouts separating it from the side walls of the store.

According to the commonality of design features, a close analogue is the 9 mm Makarov system pistol, in particular a magazine that supplies cartridges and consists of a housing, a feeder, a feeder spring and a cover (Manual on a shooting case, M .: Military Publishing House. 1985, pp. 550-552 .). The store feeder is flat, having the ability to pump slightly under the action of a spring, depending on the angle of the last cartridge lying on the feeder, while the taper of the cartridges is negligible. The diameter of the sleeve is insignificant 10 mm with a diameter of the bullet of 9.2 mm, which determines a small range of tilt angles of the feeder from the highest to the lowest positions, however, the small diameter of the cartridge and the absence of sudden changes in the cartridge when moving from the cartridge to the pool determines a small angle of elevation to direct the cartridge into the barrel chamber.

The disadvantage of this design is the applicability of this store only in a Makarov pistol. The use of another type of ammunition, including 9 mm, can lead to delays in firing and reduce the reliability of the weapon. In addition, delays can occur due to the sticking of the cartridge when it is sent from the store to the chamber. The fact is that the shutter captures the cartridge for the upper part of the bottom of the cartridge case, while the force of retraction creates a moment relative to the center of mass of the cartridge, which tends to overturn the cartridge.

The technical task of this utility model is to create a multifunctional magazine design that provides the opportunity to equip the magazine with 9 × 18 mm PM, 9 × 18 mm PMM, 9 × 19 Parabellum and 9 × 21 mm cartridges with guaranteed delivery of various types of 9 mm cartridges with a protruding edge to the sending line with pressing the cartridge to the flaps of the store, followed by sending the cartridge to the chamber.

The problem is solved in that in a store containing a housing, a feeder, a feed spring and a cover, a spring-loaded longitudinal guide mounted on the cover of the store is installed on the inner surface of the rear wall of the store housing, and a spring-loaded swinging profiled lever is installed on the feeder, the small arm of which is directed to the store feeder, and the profiled surface is directed to the inner surface of the back wall of the store, which provides a change in the length of the upper plane of the feeder, in depending on the type of cartridge used.

The use of a spring-loaded guide on the inner surface of the rear wall of the magazine case and a spring-loaded element of the upper feeder plane allows the magazine to be equipped with 9 mm cartridges of various lengths (9 × 18 or 9 × 19 or 9 × 21 mm), which will ensure reliable feeding of cartridges into the magazine sending line in the magazine located in the handle and subsequent dispatch from the store to the cartridge chamber.

Guaranteed preload of cartridges is provided by changing the position of the feeder, which is in direct contact with the spring.

This eliminates the possible jamming of cartridges when moving them up to the flaps of the store, which will not lead to a delay when firing in the form of a cartridge pass or sticking it.

The proposed technical solution provides (in relation to the requirements of the development of a pistol magazine for various types of 9 mm cartridges) the following:

- ensure that each upper cartridge is pressed against the bends of the magazine case, due to the pressing of cartridges to each other as the cartridges are used up, which will be ensured by the capabilities of the spring;

- the exception of wedging cartridges when feeding cartridges up due to the fixed position of the feeder;

- Ensure reliable chambering of the cartridge into the chamber of the barrel;

- multifunctionality of weapons will be ensured through the use of a wider range of ammunition when replacing the gun barrel, using a single store;

- simplifies the design of weapons with the introduction of a multifunctional store.

Therefore, the claimed utility model meets the requirements of novelty.

The essence of the utility model is illustrated in the drawings of FIG. 1, FIG. 2.

As can be seen from FIG. 1 store of the proposed design consists of a housing 1, a feeder 2, a feed spring 3 of the magazine cover 4. On the inner surface of the rear wall of the magazine housing 1, a spring-loaded longitudinal guide 5 is installed, and a spring-loaded swinging profiled lever 6 is mounted on the axis 2, the small shoulder of which is directed to the feeder 2 store 1, and the profiled surface is directed to the inner surface of the rear wall of the store 1, which provides a change in the length of the upper plane of the feeder 2, depending on spolzuemogo cartridge. Between the inner surface of the rear wall of the housing 1 of the store and the spring-loaded longitudinal guide 5 there are two springs 7 made in the form of curved plates, the curved parts of which are turned in opposite directions. The implementation of the longitudinal guide 5 spring-loaded springs 7 due to the need for contact with the guide 5 as the sleeve and its flange. The spring-loaded longitudinal guide 5 abuts the lower end against the ledge 8, made integral with the cover of the store 4.

To equip the magazine with cartridges, hold the case 1 of the magazine with your left hand, insert the cartridges 9 one after the other with the right hand, pressing with your thumb until the cartridge protrudes beyond the upper curved edges of the side walls of the magazine case 1, push the cartridge close to the capsule to the spring-loaded longitudinal guide 5 of the housing 1 of the store. In this case, two springs 7 are compressed, made in the form of a curved plate, the curved part of which is facing in opposite directions. The longitudinal guide 5 spring-loaded by springs 7 provides the necessary contact of the cartridge capsule with the longitudinal guide 5, tight compression of the cartridges in the magazine case 1 and the prevention of wedging of the cartridges when feeding the cartridges up due to the fixed position of the feeder 2.

In FIG. 2 shows the location of the elements of the store when equipped with its various types of 9 mm caliber cartridges: 9 × 21, 9 × 19 and 9 × 18.

When using the proposed store, the positive effect compared to the prototype is expressed in the multifunctionality of using different types of cartridges of 9 mm caliber, with the introduction of a single pistol magazine, improving the reliability of the store, increasing the reliability of the cartridge being sent into the barrel chamber, in the exclusion of delays in the form of a pass or sticking of the cartridge when sending it with moving parts, in improving the operating conditions of the gun and simplifying the design of the gun.

The proposed design of the store can be implemented in almost all samples of domestic small arms.

The technical result of the proposed utility model is to create a simple, reliable universal box magazine, allowing the magazine to be equipped with 9 mm cartridges of various lengths (9 × 18 or 9 × 19 or 9 × 21), which will ensure reliable supply of cartridges in the magazine for delivery and subsequent sending the cartridge from the store to the chamber.
