Description

FIELD OF TECHNOLOGY

SUBSTANCE: invention relates to firearms, to devices for feeding cartridges when firing from automatic double-barreled weapons with horizontal barrels.

LEVEL OF TECHNOLOGY

Known standard magazine for the AK-74, designed for 30 rounds.

The standard store is a prototype.

Criticism of the prototype

Manual reloading of a standard magazine is carried out one cartridge at a time while overcoming the increasing resistance of the power spring, which leads to a cost of time and effort.

During long-term storage of a loaded standard magazine, periodic recharging is required to relieve the tension of the compressed power spring.

When using a standard magazine with a double-barreled Kalashnikov assault rifle (RF patent No. 2619975) or a double-barreled Kalashnikov machine gun (RF patent No. 2687334), it is required to attach two magazines, one for each barrel, which increases the time to bring the weapon into combat state.

DISCLOSURE OF THE INVENTION

The magazine-case for a double-barreled Kalashnikov machine gun consists of a channel for loading cartridges of the right barrel Fig. 1 item 3 and the channel for loading cartridges of the left barrel FIG. 1 item 6. located on the common rear wall of FIG. 2 p. 11, at some distance from each other horizontally. This distance is determined by the distance between the barrels of the Kalashnikov double-barreled machine gun. In the middle between the channels for loading the cartridges is the compartment of the cartridge feeding mechanism FIG. 1 p. 5.

The pencil case is straight FIG. 2 (side view).

In the upper part of each channel for loading cartridges there are standard heads (as in the prototype magazine) for attaching to the barrels of FIG. 1 p. 2.

The cartridges in the channels are arranged in a "checkerboard" order. FIG. 1 item 7, as in a standard prototype store, and are fed upward by the pusher FIG. 1 p. 8.

At the front, the magazine-case is closed by a flat, completely sliding down front cover Fig. 1 item 1, which is fixed in the closed state by the latch of FIG. 1 p. 9.

The cartridge feeding mechanism consists of a tension force spring FIG. 3 of item 13 connected to the movable block of FIG. 3, item 14, through which the flexible cable of FIG. 3. item 15, the upper end of which is fixed on the upper wall of the pencil case magazine FIG. 4 p. 22, and the lower one is thrown over the fixed blocks of FIG. 3, item 17 and is connected to the handle for tensioning the spring of FIG. 3 item 16 and FIG. 4 p. 16.

After tensioning the power spring, the hooks of FIG. 4 item 18 of the tensioning knob FIG. 4 p. 16; are installed in the hooks of FIG. 3 p. 20 pushers FIG. 3 p. 8, which, when firing, alternately moves up the cartridges into the right and left barrels.

Compression Springs FIG. 3 p. 12 do not participate in feeding cartridges into the barrels, but serve to press the cartridges in each of the channels to the roundings in the standard head FIG. 3 p. 2 after the magazine-pencil case is fully charged and, thus, prevent them from falling out before the tension of the power spring (for example, when the magazine is turned over with the front cover removed).

The use of the movable block makes it possible to move the pushers of FIG. 3 p. 8 upwards equal to the doubled elongation of the power spring of FIG. 3 p. 13.

TECHNICAL RESULT

The use of a pencil case magazine reduces the time to bring a double-barreled weapon into a combat state (reload time), since it requires only one magazine to be connected, and not two consecutively - to the right and left barrel.

The time for equipping the magazine with cartridges is reduced, since the cartridges are not inserted into the channels one by one, but are installed in 5-10 pieces and at the same time you do not have to overcome the resistance of the power spring as in the prototype magazine.

The magazine-case loaded with cartridges can be stored for a long time without the risk of "fatigue" of the power spring, since it is cocked just before use.

The increase in the number of cartridges in the store, from 30 for each barrel, depends on the use of the weapon as portable or stationary. When using a weapon as a portable one, an increase of up to 50 rounds for each barrel is sufficient. In stationary weapons, the magazine can be large and large capacity, limited by the permissible degree of elongation of the power spring.

CARRYING OUT THE INVENTION

The dimensions of the magazine-case depend on the specified number of cartridges of 30, 50, 60 and more, on the distance between the barrels of the Kalashnikov double-barreled machine gun, and the permissible tension of the power spring.

The pencil case magazine is made as follows.

From a U-shaped, for example, metal, profile, two channels are made for feeding cartridges. A slot is cut in one of the side walls of each profile. FIG. 4 p. 21, along which the pusher hook of the corresponding channel will move. The slot does not reach the upper and lower end of the U-shaped profile wall.

At the top of each profile, the standard head of FIG. 1 p. 2 for connecting to the trunks. The formation of the channel for feeding the cartridges is complete.

Both channels for feeding cartridges are installed on the flat back wall of the case, so that the walls of the profiles with slots face each other inside the case. The profiles must be parallel to each other, the top edges of the standard heads are aligned horizontally, after which the channels are attached to the back wall, for example, by spot welding.

To the resulting channels for feeding cartridges and the rear wall, the upper wall of the magazine-case with pre-installed fixed blocks is rigidly attached.

A pusher is inserted into each channel for feeding cartridges.

In each channel, under the pusher, one retaining spring is inserted.

The bottom wall of the case is inserted into the grooves, fixing the retaining springs.

The lower end of the power spring is attached to the lower wall of the case. FIG. 4 p. 13.

Attached to the upper end of the power spring is the movable block of FIG. 4 p. 14.

A cable is passed through the fixed blocks on the upper wall with a tensioning handle attached to it. FIG. 4, item 16, then the cable is passed through the movable block and is rigidly attached to the top wall of the store FIG. 4 p. 22.

WORK DESCRIPTION

Charging the pencil case magazine.

In the initial state, the magazine-pencil case is discharged, it is in a horizontal position with the front cover up.

The cartridge feeders in both channels are in any position. The power spring is not stretched.

We move the front cover of the pencil case store towards the bottom wall, remove the cover.

We shift both pushers to the bottom of the pencil case store. We install cartridges in groups of 5-10 pieces, bullets up, in one channel, starting from the lower part of the channel to the upper part of Fig. 5 p. 2.

We press on the hook of the pusher Fig. 5 item 20 in the direction of the lower wall of the magazine-case, compressing the supporting spring of FIG. 5 p. 12, and insert the last few cartridges through the standard head.

Alternatively, the last few cartridges are inserted through the top of the standard head of FIG. 5 p. 2, overcoming the slight resistance of the supporting spring of FIG. 5 p. 12,

The support spring FIG. 5, item 12, with the channel completely filled with cartridges, does not allow cartridges to spill out when the magazine is turned over, if the power spring of FIG. 5 p. 13 is not stretched.

Install the cartridges in the second channel in the same way.

We push the front cover of the pencil case store until it is completely closed.

The pencil case magazine is ready for long-term storage without tension of the power spring.

Bringing to combat mode

The pencil case store pre-filled with cartridges is placed horizontally. We move the front cover completely, grab the handle for tensioning the power spring with two fingers. Fig. 5 p. 16 and pull it towards the bottom wall of the pencil case store.

The tensioning handle pulls the cable with it. FIG. 5 p. 15, the force through the fixed blocks FIG. 5, item 17 is transmitted to the mobile unit of FIG. 5 item 14, connected to the upper end of the power spring. Power spring FIG. 5 p. 13 is stretched.

Tensioning Handle Hooks FIG. 6 item 18 are inserted into the hooks of FIG. 6 p. 20 pushers; right and left channels for feeding cartridges.

The power spring is stretched and brought into a firing position.

We insert and completely slide the front cover of the pencil case store.

The pencil case magazine is now in combat mode.

A pencil case magazine is inserted into a double-barreled machine gun. The Kalashnikov double-barreled machine gun is ready for battle.

The work of the store-pencil case when shooting

Initial position. The pencil case magazine is not connected.

In a double-barreled machine gun, the bolt of the left barrel is in the extreme forward position. The bolt of the right barrel is in the rearmost position. We move the bolt carrier of the left barrel to the rearmost position by pulling the handle in the usual way, while the firing mechanism of the left barrel is cocked, and the bolt carrier of the right barrel moves to the forward position.

We connect the magazine-pencil case to the machine gun.

Move the bolt carrier of the right barrel back. In this case, a cartridge is sent to the left barrel from the pencil case magazine, and the firing mechanism of the right barrel is cocked.

When the trigger is pulled, a shot is fired from the left barrel, then simultaneously:

- the bolt carrier of the left barrel moves back,

- cable FIG. 6 p. 15 under the action of the power spring pulls up the handle FIG. 6 p. 16, in the middle, the hook of the pusher of the bore of the right barrel Fig. 6 item 20 and the hook of FIG. 6, item 18 remain stationary, the handle of FIG. 6 p. 16 acts as a lever and lifts up the hook and hook of the left channel,

- cartridges in the left channel move upward under the action of the pusher,

- the bolt carrier of the right barrel sends the cartridge from the magazine to the right barrel and takes the extreme forward position.

The machine gun is ready to fire from the right barrel.

When fired from the right barrel, the handle hook and the hook of the left channel pusher remain stationary, and the handle of Fig. 6, p. 16, acting as a lever, moves the hook and hook of the right channel upward, and after firing from the right barrel and retreating the right channel shutter back, it moves up cartridges of the right channel.

Whether the fire is fired with single shots, dosed portions, or bursts in automatic mode depends on the position of the interpreters of the type of fire on the double-barreled machine gun.

Similarly, cartridges are fed from the pencil case magazine, if in the initial state in the extreme forward position there is the bolt of the right barrel.

After full consumption of the cartridges, the parts of the canister magazine are in the position shown in FIG. 7.

Version of the store-pencil case

When manufacturing a pencil case magazine with two power springs instead of one and two movable blocks, it becomes possible to use the magazine in a single-barrel AK. At the end of firing from one channel, the magazine is disconnected and installed again with the second channel.
