PREVIOUS TECHNOLOGY

A known system of automatic sleeveless weapons (RU 2122170, IPC F41A 9/28, F41A 5/00, F41C 3/14, publ. 11/20/1998, S. Tsvetkov), which includes a barrel, bolt, bolt frame with a gas piston, return mechanism and receiver. A distinctive feature of the system is the presence of a revolving drum in it with several chambers and blades on its surface and a tube for removing unburned particles of a propellant charge of ammunition. The camora, which is in the upper position, has the ability to perform the function of a chamber. The output tube of unburned particles of the propellant charge is located in front of the receiver with the possibility of combining with the front of the chamber of the turret drum when sending the ammunition into this chamber. The axis of the drum is the gas piston rod. Due to the presence of several chambers of the revolving drum, one of which is involved in the shot, while the others are cooled, and the enhanced ventilation provided by the blades of the revolving drum, the author believes, the danger of self-ignition of shellless ammunition is eliminated.

Disadvantages:

- the use of only sleeveless cartridges;

- cartridges are placed in the drum by horizontal shift, which creates additional friction, and the horizontal shift itself can lead to skew of the cartridge;

- complex trigger mechanism;

- There is no connection between the trigger and the trigger.

OBJECT OF THE INVENTION

The objective of the invention is the creation of a compact machine for paratroopers, tankers, rifle and special units with an almost twofold decrease in parameters in length and thickness relative to the AK-74 without reducing the barrel length, more reliable, with reduced recoil, better accuracy of fire in automatic mode, with an increased magazine capacity to 100 rounds, reducing the weight of the machine without a magazine, bringing the portable ammunition to 400 rounds without increasing the total weight of the equipment and strengthening the armor protection of the soldier.

The indicated goal in the proposed weapon for reducing weight is achieved due to the original design of the automatic gearbox and trigger mechanism, by placing the ramrod in the hollow rod, replacing the pencil case with accessories with a brush extended by the size of the cleaning ring, lack of stock, handle, heavy bolt frame, the possibility of manufacturing a receiver from shockproof plastic.

The reduction of the length of the machine is achieved by moving most of the trigger mechanism under the barrel of the machine, using the mechanism for moving cartridges into the barrel chamber in the form of an open-chamber drum, which is part of the chamber and accepts cartridges vertically, reducing the length of the barrel without reducing its threaded portion by length the middle part of the drum, which is the chamber.

The reduction of the machine in width is achieved due to the absence of a folding butt and the fact that the protruding part of the bolt does not extend beyond the cylindrical receiver and is reduced in size due to the absence of heavy mechanisms, rubbing parts and reinforced springs.

Reducing recoil during firing was decided by the direction of the powder gases in the gas tube and the movement of the piston with the rod towards the muzzle of the barrel, the use of a multi-purpose magazine with increased capacity, where the magazine serves as a heavy butt - “anvil”, as well as the use of a spring-loaded mechanism for moving ammunition.

The use of the mechanism for moving cartridges from the magazine to the chamber in the form of a drum with open chambers, where the drum is part of the chamber and is designed to receive cartridges from the magazine vertically, makes the weapon more reliable, because skew cartridges and their friction during horizontal shift.

Placing a gas tube under the barrel, placing on the piston rod located under the barrel, a drum, a bolt, a shock spring, a hook frame for the trigger mechanism, and a shock absorber spring prevents the barrel from lifting upward during automatic firing and makes the machine more balanced.

A multifunctional high-capacity store is made in the form of a box, inside of which are holders with cartridges, it serves as a stock, and in the manufacture of a store’s box from composite bulletproof fabrics or materials, it also functions as armor plates on body armor.

When transferring four spare stores on the fighter’s body in the form of armored plates, the transportable ammunition is increased to 400 rounds, and the weight of the armor is reduced due to the use of “boxed” armor, the upper layer of which significantly reduces the kinetic force of the bullet due to amortization, as well as the increased armor protection due to clips and ammunition.

SUMMARY OF THE INVENTION

The barrel 1 in the rear part has a chamber 35 for the cone, barrel sleeve and bullet barrel, as well as an opening 36 connecting the barrel with a gas pipe 5 located under the barrel 1 and directed towards the barrel barrel 1.

A piston 8 is placed in the gas tube 5, connected to the rod 7, which passes through the rear wall of the gas tube 5, is the hammer and the axis of the shock spring 19, the shock spring 15, the rod frame 9, the shutter 14, the drum 13 and is made in the form of a tube passing to the rod. The rod 7 moves freely along the barrel 1 inside the receiver 2, 3 and has attachment points to the piston 8, to the rear wall of the gas tube 5, to the frame 9, moving along the grooves 45 of the rectangular receiver 2, and also mates with the Central hole 40 of the drum 13 .

The rod 7 hits the lower part of the trigger 18, passing through the Central hole 40 of the drum 13. The trigger 18, made in the form of the letter "T", through the axis 17 passing through the center of the perpendicular, is pivotally attached to the frame with a fork 16, moving horizontally with the drum 13 in the grooves 46 of the rear plug 10 and the receiver 3 due to the connection with the left cylinder 37 of the drum 13 using a frame with a fork 16 placed between two washers 41, 42 of this cylinder 37, so that the rotation of the trigger 18 is prevented when the drum 13 is rotated. Trigger 18 with the bottom part of the slot 47 of the tube 11 of the rear plug 10 and is supported by a cut of the left cylinder 37 of the drum 13 with a return spring 12, which holds it 18 in a vertical position. The upper right end of the trigger 18 is striking, and the left, when the striker hits the capsule, acts on the locking mechanism 20 of the drum 13, not allowing the latter to move backward under the influence of powder gases when fired.

The shock spring 15 prevents the shutter 14 from moving together with the rod 7.

The gas pipe 5 is attached to the barrel 1 of the machine due to the protrusion 36, the semicircle 30 and is fixed by the trigger box 6.

The shutter 14 is inserted into the machine through the figured window 31 of the receiver 2 and is fixed by the rod 7, which is the axis of the shutter 14.

The rear cap 10 and the magazine 4 are attached to the machine with a latch 29.

The ramrod 66 is inserted into the hollow rod 7 through the front end of the gas tube 5 and is fixed by the hooks of the holder 30. Due to the absence of complex mechanisms in the machine, there is no need for a pencil case with accessories and the presence of a brush extended by a cleaning ring that can be stored in the unloading box is enough vest or in the back of the store.

The feed mechanism of the cartridges 13, hereinafter the drum 13, is a drum with several open chambers 44 located in a cylindrical receiver 2, which prevents the cartridges from falling out of the open chambers when the drum rotates and has two rectangular windows 33, 34 in the lower part for receiving cartridges and sideways for ejecting cartridges. The rectangular windows 33 and 34 in the marching state are closed by a sliding plug 27. The drum 13 is part of the chamber and is designed to receive cartridges from the magazine 4 into the drum 13 vertically, as well as to supply part of the cartridges to the chamber of the barrel 35 by rotating the drum 13 around its own axis and longitudinal movement along this axis.

The drum 13 is a stepped cylindrical part, consisting of three cylinders 37, 38, 39 of different diameters and lengths. The axial hole is made along the axis of the part — the central channel 40, by which the drum 13 mates with the axis in the form of a rod 7 and a tube 11 of the rear plug 10. In the working position, the drum 13 freely rotates on this axis, and also moves along the axis in the longitudinal direction. The middle cylinder 38 has a larger diameter with respect to the adjacent 37, 39, and on its outer surface along the entire length there are open longitudinal grooves forming chambers 44. The chambers 44 are located along the axis 40 of the drum 13, and their internal volume allows the cartridges to be freely located in them and do not go beyond the circumference of the middle cylinder 38. In this case, the length of the middle cylinder 38 is less than the cartridge so that the bullet and part of the sleeve extend beyond the cylinder 38 for placement in the chamber 35 of the barrel 1.

The right cylinder 39 is located in a circular holder 49 and on the outside has channels of a curved shape 43, providing rotation of the drum 13 by the angle necessary to change one chamber 44 to another. The channels 43 have a complex geometric shape, which allows not only to provide a change of the chambers 44, but also to introduce and withdraw the bullet and part of the sleeve into the chamber 35 of the barrel 1 and from it due to interfacing with the fixed lock 48 during horizontal movement along the axis. Curved channels 43 are connected between The number and size of chambers 44 and curved channels 43 may vary depending on the caliber of the cartridges used. The number of chambers 44 cannot be less than four:

- the first to receive cartridges from the magazine 4;

- second intermediate;

- the third is in a combat position and is part of the chamber 35;

- the fourth for the ejection of cartridges or axial cartridges.

The left cylinder 37 has a smooth surface on which there are two flat washers 41, 42 of a larger diameter than the cylinder 37. The washer 42 is located close to the middle cylinder 38 and partially overlaps the chambers 44, being an emphasis for cartridges. The washer 41 is located at some distance from the flat washer 42 and is designed to hold the forks of the frame 16 of the trigger 18.

The movement of the drum 13 back is carried out by powder gases, and forward by a return spring 12.

Magazine increased capacity 4 is made in the form of a box, inside of which are located clips 55 with cartridges. For fastening to the machine, the magazine 4 has grooves 53 and in the front part a vertical U-shaped grip 52 from lateral rolling. The window 50 is closed by a plate 51, which moves when the magazine 4 is mounted on the machine due to the interface with the edge of the profile 67 of the machine.

The capsule 54 is pivotally attached below to the wall of the magazine 4 and the first clip 55 is placed therein.

The cage 55 consists of a pusher cartridges 59 with two spring-loaded rollers 56 and a spring 60. The height of the cage 55 in the side walls has vertical slots 57, which in the lower part have a horizontal extension 58 for inserting the rollers 56 into them and fixing the spring 60 in a compressed state.

When the rollers 56 are removed from the horizontal grooves 58 by interfacing with the guide grooves 61 of the magazine 4, the spring 60 is straightened and, acting on the pusher 59, pushes the cartridges out of the holder 55. This is prevented by the plug 51 of the window 50 of the magazine 4 when closed and the plug 51 the cartridges through the window 50 enter the lower chamber 44 of the drum 13.

The holder 55 is designed to be placed in two rows of 20-25 rounds.

HOUSES EMISSION MECHANISM

The ejection mechanism of the sleeves involves the rotation of the drum 13 clockwise, the presence of a rectangular window 33 in the cylindrical receiver 3 to the right and a spring-loaded hook 28 that exits the working part into the window 33 and is mounted on the receiver 3. When the drum 13 is fed to the barrel 1, the return spring 12 hook 28 grabs the sleeve over the edge. With further advancement of the drum 13 forward, the puck 42 hits the edge of the sleeve, which throws it out of the machine.

DESCENT MECHANISM

The trigger mechanism is located according to the bullpup scheme and consists of a body 6 with hooks 63, a profile 64 for attaching to the bracket 32 of the machine, a security bracket 62 of the trigger 21, sear 23, the fuse 24, hook 21, oval 22, axles 26 and springs 25 .

When you press the tail of the trigger 21, the oval 22 raises the front end of the sear 23 upward, thereby lowering the rear end of the sear 23 down, leading it out of the hook with the frame 9 of the rod 7. The trigger 6 is inserted into the machine by inserting the profile 64 into the grooves of the barrel bracket 32 box 2 and is fixed to the machine due to the hooks 63 for the protrusions 65 of the barrel 1.

The rector

The fuse has a minimum of three positions:

1) the 1st position, when the sear 23 is blocked and the firing of a shot is impossible;

2) the 2nd position, when the right end of the sear 23 can rise up so much that it is sufficient to withdraw its left end from the hook with the frame 9 of the rod 7 and produce a shot, and while holding the trigger 21 - continuous firing;

3) the 3rd position, when the sear 23 is not limited by the fuse 24 and when you press the trigger 21, it acts on the oval 22, removing the sear 23 from the hook with the frame 9 of the rod 7, sufficient for firing a shot. With further action on the trigger 21 and moving it to the extreme left position, it disengages from the oval 22 and ceases to act on the sear 23, which, under the influence of its spring 25, returns to the hook for the frame 9 of the rod 7. Returning to the initial state, the trigger the hook 21 raises the left edge of the oval 22 until the oval 22 ceases to mate with the radius part of the hook 21 and enters the hook with the working surface with its front part.

AUTOMATIC OPERATION PROCEDURE

Shop 4 with its grooves 53 is inserted into the rectangular profile 67 of the receiver 2, 3 and is fastened forward to the machine and fixed on it against lateral rolling by entering the U-shaped front 52 of the magazine 4 into the bracket 32 of the receiver. From an arbitrary exit store 4 of the grooves of the machine holds the latch 29 of the back cover 10.

When the magazine 4 moves along the profile 67 of the receiver 2, 3, the profile 67 of the front edge comes into contact with the plate 51 of the window 50 of the magazine 4, shifts it back, opening the window 50, and releases the cartridges in the holder 55. The holder 55, which is located in the capsule 54 of the store 4 is brought into a fighting position, since the rollers 56 are brought out of the horizontal slots 58 by pressure on them of the vertical guide grooves 61 of the capsule 54.

Then, the plug 27 rises up, opening the windows 33 and 34, as a result of which the upper cartridge rises under the pressure of the spring 60 of the yoke 55 and through the window 34 enters the lower chamber 44 of the drum 13.

To bring the machine into combat position, it is necessary to remove it from the fuse 24 and by moving the shutter 14 along the grooves of the window 31, move the drum 13 with the cartridge in the lower chamber 44 along the axis, and then rotate the drum 13 around its own axis by pairing the curved channels 43 of the right the cylinder 39 of the drum 13 with a guide lock 48 rotation.

In this case, the chamber 44 with the cartridge is installed in the extreme left position, and the next cartridge occupies the space of the empty lower chamber 44 of the central cylinder 38 of the drum 13.

Then, the bolt 14 is moved forward until it contacts through the shock absorber 15 with the frame 9 of the rod 7, with a further movement of the bolt 14 forward, we compress the mainspring 19 and enter the frame 9 of the rod 7 into engagement with the sear 23 of the trigger 6, bringing the machine into combat position.

After this, the shutter 14 is again shifted back to once again rotate the drum 13, which due to the return spring 12 has taken its original position, and send the bullet and part of the sleeve into the chamber 35 of the barrel 1.

The machine is charged and ready to fire when the fuse is removed 24.

PRODUCTION SHOT

When you press the tail of the trigger 21, the oval 22 raises the front end of the sear 23 up, thereby lowering the rear end of the sear 23 down, removing it from the hook with the frame 9 of the rod 7.

The released shock spring 19, unclenching, pushes the rod 7, which, passing through the Central channel 40 of the drum 13, enters the tube 11 and hits the bottom of the trigger 18. The trigger 18 from the impact of the rod 7 is rotated around the axis 17 of the frame 16 and its right side - strikingly - strikes the cartridge’s capsule, simultaneously acts on the locking mechanism 20 with the left part and, acting on the principle of “rocker arm”, lowers the front part of the locking mechanism 20 downward, locking the drum 13 during firing.

After the shot, the powder gases pushing the bullet through the hole 36 enter the gas tube 5, pushing the piston 8 with the rod 7 in the direction of the muzzle cut to the extreme right position, compressing the shock spring 19 and releasing the trigger 18.

Under the influence of the return spring 12, the trigger 18, resting against a slice of the left cylinder 37 of the drum 13, takes a vertical position, coming out of contact with the capsule and the locking mechanism 20.

Freed from the action of the trigger 18, the locking mechanism 20 rises up due to its spring left side, freeing the drum 13. The drum 13, under the influence of powder gases, moves back to the leftmost position, removing part of the sleeve from the chamber 35, and rotates to the required angle by pairing grooves 43 of the right cylinder 39 of the drum 13 with a fixed lock 48.

Extremely compressed return spring 12, acting through the trigger 18, moves the drum 13 forward from the extreme left position to the extreme right and leads part of the cartridge located in the upper chamber 44 into the chamber 35 of the barrel 1, and the next cartridge from the lower chamber 44 of the drum 13 rises clips 55 of the magazine 4. When the drum 13 moves to the barrel 1 with a return spring 12, the hook 28 captures the sleeve by the edge. With further advancement of the drum 13 forward, the puck 42 hits the edge of the sleeve, which throws it out of the machine.

At this time, the rod 7 with the piston 8 under the influence of powder gases moves to the extreme right position, compressing the shock spring 19.

For single shooting, the fuse 24 is set in such a position that when pulling the trigger 21, he not only lowers the sear 23 through the oval 22, withdrawing it from the hook with the frame 9 of the rod 7, but also with the further translation of the trigger to its leftmost position leaves the hook with the oval 22 and can not act on the sear 23, the left end of which, under the influence of the spring 25, is set to the position ready for engagement with the frame 9 of the rod 7. Next, the shot production process described above. When releasing the trigger 21, he, returning to the initial position, raises the left edge of the oval 22 until the oval 22 ceases to mate with the radius part of the hook 21 and enters the hook with the working surface with its front part, and the machine is ready to fire.

For automatic firing, the fuse is set in a position where the trigger 21 does not come out of the hook with the oval 22. Therefore, when you press the tail of the trigger 21, the oval 22 raises the front end of the sear 23 up, thereby lowering the rear end of the sear 23 down, bringing it out hook with the frame 9 of the rod 7, and holds the sear 23 in this position, allowing the rod 7 to move freely in the machine.

The process is repeated when the trigger 21 is pressed. If the hook 21 is released, the sear 23 rises upward by the spring 25, enters the hook with the frame 9 of the rod 7 and fixes the rod 7 in the extreme right position. The shooting stops, and the machine is put into a combat position, ready for firing shots.
