Description

The invention relates to the design of stores for small arms, namely, for pistols.

A well-known magazine for a TT pistol of 7.62 mm caliber, having a box-shaped case, a magazine cover, a feeder spring and a cartridge feed with a hook. The case of the store and the feeder spring have an increased length, allowing you to equip the store with a large number of rounds / UA patent No. 66592, IPC F41A 0009/61, publ. 2003 /. The magazine is designed for use in pistols with an internal button-operated magazine latch, as in a TT pistol, and is not suitable for use in pistols with an external magazine latch on a handle, as in a PM pistol.

Known adopted as a prototype full-time gun shop PM, which consists of a housing, a feeder with a feed spring and a cover. The case of the store connects all its parts. The upper edges of the side walls of the housing are bent inward to hold the cartridges and the feeder, as well as to guide the cartridges when they are fed into the chamber by the shutter. The case has windows in the side walls to reduce the weight of the magazine and to determine the number of cartridges in the magazine, at the bottom there are curved outward edges of the housing for the magazine cover, a protrusion for the magazine latch, a cutout for easy passage of the left bend of the magazine cover and a gutter for the tooth to pass. The feeder serves to feed the cartridges. It has two bent ends that direct its movement in the store. On one of the bent ends of the feeder on the left side there is a tooth to turn on the slide stop for the exhaustion of all cartridges from the magazine. The feeder spring serves to feed up the feeder with cartridges when firing. The lower end of the spring is bent to lock the magazine cover. The latter has an opening for the bent lower end of the feeder spring and bends, with which the cover is worn on the lower edges of the side walls of the store bent outward (technical publication Makarov Pistol PM, O. Alekseev, F. Mikhailov TT, Makarov, PSM).

Due to the design features of the external magazine latch, a higher-capacity magazine cannot be used in the PM pistol, since when a large-capacity magazine is installed, there is no access to the latch and it cannot be removed to remove the magazine. The standard external latch itself for a standard ordinary magazine is not always convenient for replacing the magazine in its design, which reduces the reliability of the gun and its rate of fire.

An object of the invention is to increase the magazine capacity for cartridges while achieving greater convenience in removing it from the gun and installation.

The stated technical problem is solved in that a magazine for a Makarov pistol (PM) of 9 mm caliber, containing a rectangular case, having left and right side walls with windows made in them and with upper edges bent inward, and on the left side wall there is a passage for passage the tooth of the feeder, housed in the housing together with the spring, on the back wall of which there is a protrusion for the latch, and a cover in the lower part of the housing with bends for its fastening on the edges of the housing bent outward and an opening for fixing the cover to the bottom the bent end of the feeder spring, according to the invention, the case of the proposed store is made elongated, and the feeder spring with a large number of turns for an increased number of cartridges, while the body is equipped with a latch retraction mechanism made in the form of a stop bracket mounted on the store case and a lever with a spring mounted on an abutment bracket using an axis.

The technical task is also directed to the fact that the magazine case is elongated to accommodate from 9 to 20 or more cartridges with a corresponding increase in the number of turns of the feeder spring.

The solution of the technical problem is achieved by increasing the length of the protruding part of the store casing in accordance with the required number of cartridges - from 9 to 20 or more, with a corresponding increase in the number of turns of the feed spring. At the same time, by supplying the magazine with a latch retraction mechanism, which has a simple structure, it becomes possible to install a magazine of any length in a simple and convenient way and remove it from the handle of the gun without changing the design of the Makarov pistol itself (PM).

The invention is illustrated by drawings, where in FIG. 1 is a left side view of a magazine not charged with cartridges; in FIG. 2 is a view A of FIG. 1 unloaded ammunition store; in FIG. 3 - shows a left view of a magazine loaded with cartridges; in FIG. 4 - a PM pistol is shown with a 16 round magazine inserted in it with a sectional view of the latch retraction mechanism; in FIG. 5 is an enlarged sectional view of a latch retraction mechanism; in FIG. 6 is an enlarged sectional view of the latch retraction mechanism at the time of release of the latch by the lever for pulling the magazine out of the handle of the gun; in FIG. 7 - presents a magazine for 12 rounds with an increased long case L1; in FIG. 8 - 16 rounds with an increased long housing L2; in FIG. 9 - 20 rounds with an increased long body L3.

A magazine for a Makarov pistol (PM) of 9 mm caliber contains a rectangular housing 1 having left and right side walls 2 and 3, respectively (see Figs. 1 and 2). In each side wall 2 and 3, windows 4 are made to reduce weight and determine the number of cartridges 5 in the magazine (see Fig. 3). In the housing 1 is also placed a feeder 6 together with a spring 7 for feeding cartridges 5 into the chamber of the gun when firing. On the left side wall 2 below the window 4 there is a groove 8 for passage of the tooth 9 along it. The latter is made on one of the bent ends 10 of the feeder 6 and serves to turn on the shutter delay for expending all cartridges from the magazine. The bent ends 10 play the role of the guides of the feeder 6 when it moves in the housing 1. On the rear wall 11 in the middle or lower part of the housing 1, depending on the capacity of the magazine, a protrusion 12 is made to fix the magazine in the handle of the gun using the latch 13 (see Fig. . 4, 5 and 6), which is mounted in the handle of the gun with a screw 14. The upper edges 15 of the side walls 2 and 3 are bent inward to hold the feeder 6 with cartridges 5 in the housing 1, as well as to guide the cartridges 5 when they are fed into the chamber pistol shutter. In the lower part of the housing 1 (see Fig. 1) there is a cover 16 on which there are bends 17, with which it is put on the lower edges 18 of the side walls 2 and 3 bent outward. In addition, in the cover 16 there is an opening 19 for fixing it with the lower bent end 20 of the spring 7 of the feeder 6. For free passage of the left bend 17 of the cover 16 when putting it on the case of the magazine 1, a cutout 21 is provided on the left side wall 2.

In this case, the store 1 is made elongated, and the spring 7 of the feeder 6 with a large number of turns.

In addition, the housing 1 is equipped with a mechanism 22 for retracting the latch 13 from the protrusion 12 (see Fig. 4, 5 and 6), made in the form of a bracket-stop 23 mounted on the housing 1 of the magazine, and a lever 24 with a spring 25 mounted on a bracket - emphasis 23 using the axis 26.

The mechanism 22 of the withdrawal of the latch 13 from the protrusion 12 is designed to remove the magazine from the handle of the gun.

The case 1 of the store can be made elongated to accommodate a larger number of cartridges 5, namely, from 9 to 20 or more cartridges with a corresponding increase in the number of turns of the spring 7 of the feeder 6 (see Fig. 7, 8 and 9), which can be estimated by the ratios of the lengths L1, L2 and L3 of the protruding part of the magazine case 1 beyond the limits of the handle of the gun, that is, L1 <L2 <L3.

Shop for Makarov pistol (PM) caliber 9 mm operates as follows.

At the stage of assembly of the Makarov pistol magazine (PM), they use case 1 of a given capacity for a larger number of rounds, namely, from 9 to 20 or more rounds. In this case, the longitudinal dimensions of the store’s body increase due to the part of the body 1 protruding beyond the boundaries of the pistol grip, that is, L3> L2> L1. The longitudinal dimensions of the part of the store’s case, located directly in the handle of the gun are preserved: L = const.

In addition, the feeder 6, the cover 16, as well as the configuration of the upper bent edges 15 of the housing 1 for holding cartridges 5 with the feeder 6 and the bent lower edges 18 of the housing 1 for installing the cover 16 are stored, as in the currently used Makarov pistol magazine (PM ) caliber 9 mm.

In the process of assembling a store of increased capacity for a Makarov pistol (PM) of 9 mm caliber, a feeder 6 is inserted into the bottom housing 1 from the bottom 1, after the feeder 6 is installed together with the compressed spring 7 of the entire feeder into the housing 1, on the edges 18 of the housing 1 bent from the bottom with the help of bends 17 the cover 16 is put on and fixed by the bent end 20 of the spring 7 of the feeder 6 by installing it in the hole 19 of the cover 16.

When the magazine is equipped with an increased capacity for a Makarov pistol (PM) of 9 mm caliber, cartridges 5 are installed under the upper bent edges 15 of the housing 1, while the feeder 6 is shifted down, overcoming the resistance of the spring 7. The number of cartridges is set in the magazine in accordance with its design capacity.

When firing, the Makarov pistol shutter (PM) performs longitudinal reciprocating movements, while moving forward, it engages the cartridge 5, held by the upper curved edges 15 of the magazine case 1 and moves it forward. In this case, the cartridge is released from under the upper bent edges 15 of the housing 1 and is sent by the pistol shutter to the barrel chamber. After the shot, the pistol shutter, due to the recoil from the shot, moves back together with the cartridge case 5 being shot, while the cartridge case is thrown out, and the shutter, moving back to the stop under the action of the shutter return spring, moves forward, while capturing the next cartridge 5 from under the top bent edges 15 of the housing 1 of the store, which had previously been lifted by the feeder 6 with the spring 7 upward under the upper bent edges 15 of the housing 1.

The process is resumed and repeated many times until all 5 rounds from the magazine are used up.

When installing a magazine in a Makarov pistol (PM), the shooter pushes the magazine into the handle of the gun. In this case, the protrusion 12 on the rear wall 11 of the magazine lifts the latch 13 of the magazine and, when the magazine slides all the way, the latch 13 of the magazine engages in the protrusion 12 on the rear wall 11 of the magazine, and thus, the magazine is fixed in the handle.

When removing the magazine from the gun, the shooter presses the lever 24 of the retraction mechanism of the latch 22, overcoming the resistance of the spring 25. The lever 24 thus removes the latch 13 of the magazine from the protrusion 12 on the rear wall 11 of the magazine, the magazine is released and can be removed by the arrow from the gun.

The invention allows the use of a Makarov pistol (PM) with an increased cartridge capacity in a magazine. Also, the presence of the mechanism 22 of the retraction of the latch allows you to achieve greater convenience in removing the magazine in which the cartridges ran out, this reduces the time to replace the magazine and increase the combat rate of fire of the weapon. Also, an enlarged magazine with a large number of rounds lowers the overall center of gravity of the gun, which improves aiming, stabilizes the position of the gun when firing by reducing the recoil effect and reduces the tossing of the gun barrel during firing.

Thus, the invention allows to increase the magazine capacity for cartridges when it is convenient to remove it from the gun and mount without changing the design of the Makarov pistol itself (PM).
