Description

The utility model relates to the field of weapons, namely to stores with an indicator of the availability of cartridges for small arms.

Cases of small arms stores are usually painted in dark brown or black. The opacity of the material of the wall of the case of the store does not allow to determine the quantitative content of cartridges. To control the completeness of filling (stuffing) of domestic stores with cartridges, a hole is made on the back wall of their cases: when fully packed, the cartridge igniter is visible in the specified hole. Many cases of foreign-made stores also have full marks. At the same time, the need for stores with visual (tactile) control of the expenditure of cartridges exists and is especially relevant for units of troops participating in hostilities.

For small automatic weapons, there is a serious, complicated and tedious task of counting the number of cartridges remaining in a magazine installed in a weapon, which can become even more complicated when the user deciding it is under pressure associated with saving his own life.

Therefore, there is a need to develop a system that is capable of providing information on the number of cartridges remaining in a magazine inserted in an automatic small arms loading from a breech. In addition, tactile control of their quantity is necessary in stores taken away and inserted into weapons.

A well-known universal equipment-counter of cartridges for box magazines (patent RU No. 2509283, IPC F41A 9/62, F41A 9/66, published 03/10/2014), comprising a housing, a feeder, a feed spring and a cover made in the form of an elastic-elastic traction from plastic, metal or composite material with scales applied on the draft from both sides, which determine the number of cartridges in the magazine in positions separated and inserted into the weapon. The upper end of the rod is connected to the cartridge feed, or the upper end of the feed spring, or with an intermediate support between the feed and the spring and is located inside the magazine. The lower end of the rod, with a support ring fixed to it with a clamp, is released through a hole in the magazine cover with the possibility of reciprocating movement when compressing or stretching the spring.

The main disadvantage of this technical solution is the possible engagement of the support ring for foreign objects, which can lead to inhibition of traction and the cessation of the supply of cartridges from the magazine. Difficult visual and tactile control of their number in the stores inserted in weapons during the battle.

Known cartridge counter (patent RU No. 2370718, IPC F41A 9/62, published October 20, 2009) containing a cartridge counter, a frame in which a cartridge ejection mechanism is placed, driven by a spring between the base at one end of the frame and the other end of the frame or a loading and outlet for cartridges, and the cartridge counter contains means for determining the distance between the mechanism for pushing cartridges and the base of the magazine for cartridges, made in the form of a magnetoresistor with a linearly changing characteristic and a permanent magnet, captive to the mechanism of ejection of cartridges.

The disadvantage of this technical device is its complexity, the need to change power supplies, replace a standard magazine and handgrip linings, a display that can be substantially damaged during combat operations in difficult operating conditions.

Known counter remaining in the store cartridges for small arms (patent RU No. 2427779, IPC F41A 19/01, published August 27, 2011), comprising a counter housing made shaped like a small arms body, a counter device is stored in the meter housing that maintains its state at the time of power failure, with the installer setting the number of cartridges in the store, the reader, the pulse converter to the visual image and the batteries, a display is displayed on the surface of the case formed by the image signal into a visual transducer pulse on the acquired device power button - power down, the installer amount of cartridges in the magazine and elements of the counter housing to the housing mounting firearms.

The disadvantage of this technical device is its design complexity, low operational reliability in difficult conditions of warfare, the need to change power sources, replace the standard store and the lining of the weapon handle. The shooter should be distracted, observe the display, which significantly distracts attention from monitoring the situation during the battle, the lack of the ability to tactilely determine the number of cartridges left in the store when the electrical part of the device fails.

A well-known store with an indicator of the presence of cartridges for small arms (patent RU No. 2117231, IPC F41A 9/62, published on 08/10/1998), comprising a case of non-magnetic material with windows in the side wall and a spring-loaded feeder equipped with a permanent magnet, the case windows are closed walls, and the outer walls of the windows are made of transparent material, a magnetic powder is placed in the space between the walls, and the rear walls of the windows are made of material contrasting in color with the magnetic powder.

The disadvantage of this device is its complex design, the need for a substantial alteration of the existing store for the AK series assault rifle, and it is difficult to visually and tactilely control their quantity in stores taken away and inserted into weapons.

A well-known store indicating the number of cartridges, consisting of a case with three transparent windows on the side surface, offset relative to each other across the width of the case, and a feeder, on the side surface of which are placed digital signs in three rows, sequentially located along the length of the case (AC USSR No. 2030703, F41C 25/02, F41A 9/62, published 1988). The case of the store is made of glass-filled polyamide, and the windows are made of transparent polymethyl methacrylate (organic glass).

The disadvantage of this design is its complexity, due to the use of two different polymer materials, and the high technological complexity of manufacturing, it is difficult to determine the presence of cartridges in the store in the dark and the impossibility of tactile determination of the presence of cartridges.

As a prototype, a store was selected that provides visual control of the quantity of ammunition (Patent SU No. 5149897, F41A 9/62, published 1992). Structurally, this store consists of a housing having two side, rear and front walls, a feeder with a spring and a locking bar. Visual control of the amount of ammunition is achieved by making recesses (windows) on the inside of the side walls of the case: since the thickness of the wall of the case along the recess is much less and is 0.1-0.5 mm, the case becomes sufficiently transparent over the entire surface of the recess. The walls of the store casing and the recesses (windows) are made of the same polymer material, which is preferably a glass-filled polyamide. On the inner surface of the side walls are longitudinal ribs that ensure the correct movement of the feeder and ammunition. On the outer surface of the side walls of the case there are transverse ribs that strengthen the structure and can serve as guidelines for the quantitative assessment of ammunition in the store.

The disadvantages of this design are the impossibility of controlling the entire amount of ammunition in the store, making recesses (windows) on the inside of the case wall significantly weaken the structure of the store, which can lead to mechanical destruction of the store if it accidentally falls on a solid foundation (asphalt, concrete, etc. .) and makes this design not satisfying the requirements for service strength, it is difficult to determine the presence of cartridges in the store in the dark and the impossibility of tactile determination of the presence of patras ones.

The technical task of this utility model is to create a design that provides control of the amount of ammunition that is currently in the store docked to the weapon, including in the dark with the possibility of tactile (tactile) determination of the presence of cartridges in the store and possessing the required mechanical strength.

The problem is solved in that in a store with the possibility of tactile determination of the presence of cartridges, comprising a housing having two side, rear and front walls, a feeder with a spring and a locking strip, the housing is made of high-strength polymer material, for example, glass-filled polyamide, characterized in that on the outer surface of the rear wall of the store’s case there are three recesses provided with three spring-loaded marks, and the upper mark is made on a section of the store’s case located below the docking line m gas to the receiver of the weapon, which signals about 7-8 cartridges remaining in the store, and on the bottom of the surface of the back wall of the store’s case there is a pointer mark that signals the store is fully equipped, the middle label indicates the presence of 50% or less of cartridges in the store .

The use of spring-loaded tags on the outer surface of the rear wall of the magazine case allows tactile control of ammunition that is invisible when the magazine is attached to the weapon, i.e. are in the store, not weakening attention to the situation on the battlefield.

In the dark and in conditions where there is no possibility to be distracted from aiming, the presence of cartridges in the store is determined by touch with the hand on the protruding part of the pointer mark.

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

The essence of the utility model is illustrated in the drawing of FIG. one.

As can be seen from FIG. 1, 2, the store of the proposed design consists of a housing 1, a feeder 2, a spring 3 and a locking plate 4, which is fixed to the housing by a cover 5. On the outer surface of the rear wall of the housing 1 along the generatrix there are three recesses 6, 7, 8, in which three marks 9, rigidly fixed to the leaf spring 10, and the leaf spring 10 is fixed motionless on the inner surface of the rear wall of the housing 1 (the mounting points of the leaf spring are not shown conventionally), and the upper mark 9, protruding from the upper recess 8, is made on a section of the housing magazine, located below the line of docking the magazine to the receiver of the weapon and signals the remaining 7 rounds of ammunition in the magazine, and the lower mark 9, protruding from the lower recess 6 located on the outer surface of the rear wall of the magazine’s case indicates a fully equipped magazine, the middle mark 9, protruding from the middle recess 7, located on the outer surface of the rear wall of the store’s case, signals the presence of 50% or less cartridges in the store.

The width of the recesses 6, 7 and 8 can be from 6 to 15 mm, preferably 10-15 mm, i.e. is a value that provides organoleptic (tactile) control of the presence of ammunition 11, and the height of the recesses 6, 7 and 8 is 5 mm, which provides a given service strength store. The thickness of the body wall along the recess is from 0.3 to 1.2 mm, preferably 0.5-0.8 mm, and is determined by technological requirements (with a wall thickness of 0.1-0.4 mm, high-quality molding of the body by injection molding is difficult) . The case of the store is made of high-strength polymer material.

Spring-loaded tags 9 can have risks and move freely in the recesses 6, 7 and 8 when the magazine is empty with cartridges, and can also have an external surface painted with reflective paint. Since the marks 9 are rigidly connected to the leaf spring 10 (can be fixed to the leaf spring using riveting, spot welding), in the initial position, the marks 9 always protrude in the recesses 6, 7, 8 by 4-5 mm, which allows any available organoleptic (tactile) way to control their protruding part.

The lower mark 9 in the lower part of the surface of the rear wall of the magazine case indicates a fully equipped magazine, if when you click on the lower label 9, it does not sink into the magazine 1 of the rear wall of the magazine 1, the middle label 9 indicates the presence of 50% or less cartridges in the magazine if, when you click on the middle mark 9, it does not plunge inside the magazine 1 of the rear wall of the magazine case 1, the upper marker 9 is made on a section of the magazine case 1, located below the line of docking the magazine to the receiver of the weapon, if TII on top label 9, it does not sink inside the rear housing wall 1 store store 1, which signals the remaining cartridges in the store 7-8

This location mark 9 allows for tactile control of cartridges that are in the store.

As experimentally established by the authors, it is preferable to know the presence of cartridges in the store in the amount of 100%, 50%, 75% of the initially loaded in the store 1.

This arrangement of marks 9 allows tactile determination of the number of cartridges remaining in the magazine with an error of 1 cartridge (see Fig. 2). At the same time, the lower mark 9 corresponds to the magazine capacity (availability of 30 rounds), the middle mark 9 corresponds to the presence of 50% rounds, and the lower mark corresponds to the presence of 75% rounds, i.e. 2-3 short bursts remain.

If, when you click on label 9, it does not plunge inside magazine 1, this indicates the presence of cartridges in magazine 1. Label 9 is clearly visible on magazine 1, and by its ability to plunge inside magazine 1, the number of cartridges remaining in the magazine is judged.

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

When shooting, the presence of cartridges in the store is controlled both visually and tactilely.

When conducting military operations (expenditure of cartridges), their presence is determined by touch with a hand pressing on the mark 9 located on the back wall of the store towards the store. If mark 9 is not recessed into the magazine, it means that there are still cartridges, if label 9 is pressed into the magazine, it means that there are no cartridges in the magazine or when the upper label 9 is sunk, less than 7-8 rounds of 11 are left in the magazine.

The technical result of the proposed utility model is to create a simple, reliable universal indicator of the presence of cartridges in box magazines, which allows visual and tactile control of their quantity in the box magazines taken and inserted into weapons.

The device has a minimum weight and can be easily integrated into any box magazine of the machine with a spring feeder cartridges.
