Description

FIELD OF TECHNOLOGY TO WHICH THE UTILITY MODEL RELATES

The technical solution relates to the field of military equipment, namely to the element of ensuring combat functioning and storing ammunition, which is the cartridge box of an automatic small arms weapon (for example, a machine gun).

According to GOST 28653-90 of 2008, automatic small arms are small arms with fully automated reloading. As an element to ensure the functioning of automatic small arms, a cartridge box and a cartridge strip are used for firing and storing ammunition (cartridges). According to GOST 28653-90 of 2008, a machine gun cartridge box is a box for placing small arms cartridges loaded into a cartridge belt fed from it when firing at a machine gun. A machine gun cartridge belt is a belt with sockets for placing small arms cartridges or cartridges connected to each other by flexible links (GOST 28653-90 of 2008).

BACKGROUND OF THE ART

In 1961, the Kalashnikov machine gun - PK - was adopted into service by the USSR. According to the Manual of the Ministry of Defense of 1971, this machine gun is designed for prone shooting from a bipod and firing from a rest (https://nastavleniya.ru/PK/pk12.html, date of access 07/31/2023, Manual on small arms 7.62 mm machine gun Kalashnikov (PK, PKS, PKB, PKM and PKT, 1971). Standing shooting is provided only in case of shooting from cover. For example, from a window. However, in modern combat the machine gun is used in the Petrov stance (https://www.youtube. com/watch?v=V_tcuL-wCLM&t=278s, “Weapon holding exercise according to Petrov’s method”, 2013, see according to timing 4:15, access date 07/31/2023) Including on the go.

A compact cartridge box for a machine gun with 100 rounds of ammunition is known (https://nastavleniya.ru/PK/pk6.htm, access date 06/05/2023, Manual on small arms 7.62 mm Kalashnikov machine gun (PK, PKS, PKB and PKT), 1971, pages 86-87), containing a metal body, a unit for attaching the box to the machine gun bracket, made on the surface of the box, which in the installed state is oriented essentially upward; a hinged cover, which is formed in the surface of the housing, which in the installed state is oriented substantially upward; lid locking unit containing a clasp and a wrap. The known box is attached to the machine gun bracket before firing. It has a handle for carrying the box and a hinged lid that is secured with a clasp and wrap. The cover has: two hooks, a protrusion and a latch for attaching the box to the machine gun bracket; a flap valve that closes the window for the passage of the tape; a rounded protrusion to guide the movement of the tape when shooting. In this case, the known cartridge box is designed in such a way that its upper side in the installed state is located essentially horizontally close to the lower surface of the weapon; and the front side is located in a plane perpendicular to the direction of the weapon barrel.

Firing a machine gun with a well-known cartridge box installed in a standing position is only possible if the shooter is tall and has great physical strength. Moreover, due to the heavy load on the shooter’s outstretched front arm, the duration of shooting while standing is very limited. The reason for this is, on the one hand, the large distance from the end of the butt to the section of the fore-end that is not blocked by the installed cartridge box, and on the other hand, the peculiarities of balancing the mass of the machine gun: the mass of the cartridge box with the tape is shifted close to the fore-end. The weight of a loaded cartridge box is up to 30; from the weight of the machine gun, which is why this arrangement leads to an imbalance of the machine gun, which is not sufficiently suitable for shooting while standing.

Thus, it is acceptable for a shooter with a height of about 175 cm to hold his front hand in the position shown in Fig. 1-2 - place in front of the bracket for attaching the cartridge box. It is not possible to place it closer to the butt, since there is a window and a cartridge feed mechanism there.

With a standard cartridge box installed, this position of the front hand is impossible, since the side dimensions of the cartridge box protrude beyond the dimensions of the gun, resting on the forearm and preventing an acceptable position of the front hand close to the cartridge box. Figures 3 and 4 show the optimal position of the hand with the box installed, however, they show that such a position is impossible, since the body of the cartridge box does not leave room for placing the forearm and holding the weapon by the forearm close to the machine gun bracket for the cartridge box. For this reason, shooters of average height are forced to work without a cartridge box, using a short belt, or installing a special handle for hand-held shooting. The handle restricts movement (does not allow you to move the front hand along the fore-end), is unsafe to use and makes it difficult to shift the weapon to change hands.

Thus, the main disadvantage of the known device is the narrow range of possibilities for using the device in a standing position using a cartridge box: the required anthropometric data of the shooter, the possible positions of the front hand on the forearm are limited, in addition, due to the location of the center of mass of the machine gun close to the front hand, the time is reduced , during which the shooter can physically fire.

UTILITY MODEL DISCLOSURE

The challenge faced by the developers of the disclosed technical solution was to reduce the above-mentioned limitations.

This problem was solved by creating a cartridge box for a machine gun containing

frame;

connection point between the cartridge box and the weapon bracket, connected to the upper side of the cartridge box.

In this case, the cartridge box differs in that the connection unit is connected to the upper side by means of an extension made in such a way that the upper side of the body in the installed position of the box is located at an angle of 30° to 50° to the direction of the weapon barrel.

The technical result achieved by the disclosed solution is to provide a wider range of possible grip positions of the front hand on the forend of a machine gun while improving the balance of the weapon for standing shooting.

To a higher degree, the technical result is achieved in the embodiment of the cartridge box, characterized in that the extension is made in such a way that the site of the connection unit is offset relative to the perpendicular to the center of the upper side of the cartridge box to the front side of the cartridge box.

OPTIONS FOR IMPLEMENTATION OF THE UTILITY MODEL

In accordance with the disclosed technical solution, the cartridge box 1 contains a housing 2. The housing 2 in a preferred embodiment is made in the form of a box made of sheet metal. In a preferred embodiment, the housing 2 contains a hinged cover, which is made in the surface of the cartridge box 1, which in the installed state of the cartridge box 1 is oriented laterally with respect to the direction of the machine gun barrel. Housing 2 is designed to accommodate a cartridge belt (not shown) and contains a window for feeding the tape into the feed mechanism of the cartridge belt of a weapon (for example, a machine gun). In a preferred embodiment, the window for feeding the tape of the cartridge box 1 is equipped with a valve 9.

In accordance with the disclosed technical solution, the cartridge box 1 contains a connection unit 3 of the cartridge box 1 with the weapon bracket, connected to the upper side 4 of the cartridge box 1. By the upper side 4 of the cartridge box 1 it is necessary to understand the side which (or the center of which) in the installed state is located closer to the weapon than the other sides (or their centers). Moreover, in accordance with the technically disclosed solution, the connection node 3 is connected to the upper side 4 by means of an extension 5, made in such a way that the upper side 4 of the body 2 in the installed position of the box 1 is located at an angle of 30° to 50° to the direction of the weapon barrel. In the most preferred embodiment of the technical solution, the upper side of the housing 2 in the installed position of the box 1 is located at an angle from 38° to 42° to the direction of the weapon barrel; this angle, on the one hand, ensures unhindered exit of the cartridge belt from box 1, on the other hand, it ensures the lowest height of the weapon, and on the third, it allows the shooter to keep the hand of the front hand close to the weapon bracket for the cartridge box 1, providing, due to the inclination of the cartridge box 1, sufficient space for the forearms of the shooter's front hand near the machine gun bracket.

The extension cord 5 in various embodiments of the technical solution can be made in various forms. In the embodiment presented in Fig. 7, it is made in the form of two curved metal plates located essentially perpendicular to the upper side 4 of the box 1 and permanently connected to the cartridge box 1 and to the connection unit 3 of the cartridge box 1 with the weapon bracket. The shape of the extension 5 is determined by the required position of the cartridge box 1 relative to the weapon bracket: the angle of inclination of the cartridge box 1 relative to the weapon barrel, the distance from the weapon bracket and the displacement of the box relative to the connection node 3. Specific forms of execution of the extension 5 can be developed by a specialist in the field of technology, taking into account the given required position of the cartridge box on the basis of known principles and rules for the manufacture of relevant parts.

To ensure a more convenient positioning of the shooter's front hand close to the weapon bracket and, accordingly, the connection node 3, in some embodiments of the disclosed technical solution, the connection point of the extension 5 with the box 1 is offset from the center of the upper side 4 of the cartridge box 1 to the front side 6 of the cartridge box 1 By the front side 6 of the cartridge box 1 it is necessary to understand the side different from the top side 4 and located in the installed state of the cartridge box 1 closer to the end of the weapon barrel. This offset allows the body 2 of the cartridge box 1 to be moved rearward, giving the shooter more room for the front hand. Also thanks to this, a taller shooter can move his front hand either close to the bracket for quickly tracking the sight behind the target, or position it further along the forearm for more accurate aimed shooting.

In some embodiments, the extension 5 is designed in such a way that the platform 10 of the connection node 3 is offset relative to the perpendicular to the center of the upper side 4 of the cartridge box 1 to the front side 6 of the cartridge box 1. By platform 10 here we must understand the plastic by which the hooks 7 are connected to each other and latch 8 nodes 3 connections.

For the same purposes, in some embodiments of the disclosed technical solution, the junction of the extension 5 with the box 1 is offset from the center of the top side 4 of the cartridge box 1 to the front side 6 of the cartridge box 1. In such embodiments, the extension 5 may be located at an angle other than 90° in relation to the top side 4 of box 1.

The length of the extension 5 is determined by the angle of its location relative to the upper side 4 of the box 1 and the distance by which it is necessary to remove the body 2 from the weapon bracket in order to ensure unhindered installation of the cartridge box 1 on the weapon. In fact, this distance is determined by the specific angle of the upper side of the body 2 in the installed position of the box 1 to the direction of the weapon barrel, the shape of the upper side 4, and the offset of the junction of the extension 5 with the box 1 relative to the center of the upper side 4 of the cartridge box 1 to the front side 6 of the cartridge box 1.

In the preferred embodiment of the disclosed technical solution, the connection node 3 is designed to be connected to the machine gun bracket and includes at least hooks 7 and a latch 8. Such a design of the connection node, subject to the appropriate dimensions of its elements, can be made to be connected to the Kalashnikov machine gun bracket , for example, models PC, PKM, PKMN, PKS, PKB, PKT or its other modifications.

Both due to the location of the upper side 4 of the body 2 at an angle, and due to the displacement of the junction of the extension 5 with the box 1 relative to the center of the upper side 4 of the cartridge box 1, the center of mass of the cartridge box 1 in the installed position is shifted (relative to the known analogue) from the forend closer to the butt weapons. Since the mass of the cartridge box with the belt is up to 30% of the mass of the machine gun, such a displacement significantly improves the balance of the machine gun, shifting the center of mass of the machine gun from the outstretched front hand to the shooter’s body. This makes it easier to shoot from a standing position and increases the amount of time you can shoot while standing before fatigue sets in.

This technical solution has been described in detail with reference to individual variants of its implementation, but it is obvious that it can be implemented in various variants without going beyond the stated scope of legal protection determined by the formula of the utility model.
