Description

The utility model relates to military accessories and is designed to simplify the process of equipping magazines with Kalashnikov assault rifles (AK) in caliber 5.45×39 mm.

As you know, during exercises or during direct combat, a shooter belonging to the armed forces of the Russian Federation needs to monitor the number of cartridges and, if necessary, replenish them in a timely manner, which is especially important when pre-equipped magazines are used up.

Currently, AK magazines in caliber 5.45×39 mm (AK-74, AK-74M, AKSU, AK-12, etc.) are equipped either manually or using special devices manufactured by the military industry.

So, the standard accelerator of equipment is an adapter and a clip attached to it, into which cartridges must be inserted in advance.

It is also known device [US Patent No. 4,574,511, publ. 03/11/1986], containing a hollow body and a spring-loaded handle for sending cartridges pre-installed on a special platform into the store.

Known accelerator equipment [US Patent No. 4,689,909, publ. 09/01/1987], which is a nozzle with a rod that sinks the ammunition into the magazine.

Known accelerator equipment [US Patent No. 4,879,829, publ. 11/14/1989], containing a hopper for stacking cartridges from the tray in a strictly defined position (bullet up) and a rammer that rotates due to the presence of a handle.

Also known accelerator equipment [US Patent No. 6,754,987 B1, publ. 06/29/2004], containing a hollow body, a clip for pre-installation of cartridges into it and a pusher that advances them towards the store.

Known accelerator equipment [US Patent No. 7,059,077 B2, publ. 06/13/2006], representing a platform with grooves for laying the magazine and cartridges with a moving slider.

A device for equipping stores is known [US Patent No. 7,805,874 B2, publ. 5.10.2010], having a body attached to the magazine and designed to fit into it clips with pre-installed cartridges that can be displaced by the pusher.

Also known accelerator equipment [US Patent No. 8,931,199 B1, publ. 01/13/2015], containing a body in which the cartridges are placed from the tray in one position, and a pusher that advances the ammunition into the magazine.

A common disadvantage of these devices is the requirement from the user to independently position the cartridge in front of the equipment, which is comparable in time to the usual manual delivery of ammunition to the store and may be difficult in direct combat operations, when fine motor skills of the fingers can be impaired under stress.

The accelerator "AK-47 ELITE MAGAZINE LOADER" (https://magpump.com/products/rifle-magazine-loaders/ak-47-elite-magazine-loader) is the closest in terms of the level of technology to the claimed device. prototype. This device contains a massive body with the possibility of fixing on the table, a removable hopper and a control handle, when pressed, the cartridge is moved and loaded into the magazine.

The disadvantage of the described device is the inability to fold the hopper, as well as use the accelerator, holding it in your hands, since the design of the body provides for location strictly on a flat and hard surface, which is not always possible to find in the field, which makes the operation of this device, as well as its transportation, inconvenient.

The objective of the utility model is to create an easy-to-handle and user-friendly device that allows loading AK magazines in caliber 5.45×39 mm without prior orientation of the cartridges.

EFFECT: simplification of the process of equipping stores of Kalashnikov assault rifles (AK) in caliber 5.45 × 39 mm is achieved by creating a device, which is represented by a body made of two symmetrical parts 1 and 2, each of which contains a figured protrusion 3 for positioning the cartridge, a chute 4 for the rod 5 of the pusher 6, recesses 7 for stop springs 8 and 9, as well as mounting grooves 10 for the cartridge receiver 11.

When assembled, the case opens with a hole that exactly repeats the receiver shaft, and contains a ledge 12 for a hook, and an annular lock 13 with a slider 14, located on the opposite side, are designed to fix the support protrusion of the AK magazine.

The bunker, designed for 30 rounds of caliber 5.45×39 mm, contains fabric side walls 16, fixed by gluing their edges on the support ring 28 (top) and adapter 29 (bottom), made folding (due to the presence of spacers 17 and hangers 18 ) and is attached to the cartridge receiver 11, which contains a diamond-shaped hole 19, stops 8 and 9 and is closed by a protective cover 20 for the protection of the latter. In the folded state of the bunker, the spacers 17 are located in the holes 30 on the support ring 28, in the expanded state - in the holes 31 and 15 (of the support ring 28 and the adapter 29, respectively).

Stops 8 and 9 have pins 21 for movable installation in the recesses 22 of the cartridge receiver 11, as well as guides 23 and 24 under the protrusions 25 of the pusher 6.

The return spring 26 is enclosed along the rod 5 between the parts 1 and 2 of the device body and the handle 27, which ensures the fixation of the pusher 6 in the starting position.

In FIG. 19 shows a diagram of changing the position of the cartridge in the device as the rod 5 moves with the pusher 6 towards the magazine (the pusher 6 is displaced so much that its protrusions 25 change the position of the guides 23 and 24 stops 8 and 9 and the lower cartridge moves under its own weight through the diamond-shaped hole 19 into the body of the device).

In FIG. 20 shows a diagram of changing the position of the cartridge in the device as the rod 5 with the pusher 6 moves towards the magazine (the pusher 6 advances the ammunition, which slides with its shoulders along the figured ledges 3 of parts 1 and 2).

The utility model is used as follows.

To prepare the device for operation, the hopper with its adapter 29 is attached to the cartridge receiver 11 rigidly fixed in the seating grooves 10 to the upper edge of the protective casing 20 and straightened by lifting the support ring 28 up from the body along the shoulders 18 and fixing it in this position with spacers 17, which are removed from the holes 30 and are installed in the holes 31 and 15. In this case, the fabric walls 16 are stretched, which ensures a reliable retention of the cartridges.

Then, a standard magazine for AK is installed in the case in such a way that its hook goes beyond the ledge 12, and the support ledge covers the ring retainer 13 and is pressed by the slider 14.

Next, cartridges are placed in the hopper (the design of the device allows you to use cartridges directly from the pack, removing only the paper layers, the orientation of the bullet and the bottom of the sleeve can be any).

After that, holding the body of the device with the magazine towards him, the user begins to press the handle 27 of the rod 5, thereby shifting the pusher 6, which, moving forward, interacts with the guides 23 and 24 with its protrusions 25, which sets in motion the spring-loaded stops 8 and 9.

Stop 8, slightly turning on its pegs 21 in recesses 22 and protruding into the chamber 11, fixes the upper cartridge, and stop 9, on the contrary, comes flush to the wall, freeing the bottom one.

This ammunition under its own weight is shifted down and falls into the diamond-shaped hole 19, designed for precise orientation of the cartridge with the bottom of the sleeve up.

In this position, the cartridge, under the action of the pusher 6, moves forward, touching with its shoulders the curly ledges 3 of parts 1 and 2 of the body, and eventually goes behind the magazine jaw, which achieves its equipment. After a characteristic click, indicating that the cartridge is in the magazine, the user takes the rod 5 back, which, under the action of the return spring 26, slides along the grooves 4 and finds itself in its original position, while the pusher 6, moving in the opposite direction, changes the position of stops 8 and 9 to starting, which allows you to add a new cartridge from the hopper to the cartridge holder 11.

At the end of the cycle of equipping the store, it is removed, and the hopper is disconnected from the chuck 11 and folded to save space, for which spacers 17 are removed from the holes 31 and 15 and the support ring 28 is shifted to the adapter 29 along the shoulders 18.

The positive effect of the claimed technical solution lies, first of all, in the absence of the need for preliminary orientation of the ammunition before the direct loading of the AK magazine, which significantly saves time, and the folding hopper does not take up much space and is designed for a standard number of cartridges, allowing them to be used directly from cartridge zinc packs.

The utility model can be used in exercises or in direct combat when equipping magazines of Kalashnikov assault rifles (AK) in caliber 5.45 × 39 mm without preliminary orientation of cartridges.
