Abstract

This invention relates to arms. The automatic fire-arms has a barrel, round this there are placed a gas chamber, a gas piston, opposing mainspring andbreech mechanism. To increase the effectiveness of the arms, the opposing mainspring is placed in the spool and interacts with the traction and transfers with its teeth motion to the back end of the lower part of the toothed lever, it turns the lever the upper part of which goes out of the support of the breech mechanism with liberation of the breech mechanism and giving it ability to move back in free way.

Description

The invention relates to the field of armaments, in particular, to the design of submachine guns, pistols, submachine guns and other military weapons, civilian, sports and other.

A well-known submachine gun, which contains a barrel, a barrel (bolt) box, a casing with ventilation holes, a shutter frame, a trigger mechanism with a trigger, a recoil spring, a magazine and aiming devices located on the casing and on the receiver box (see Fig. A.V. Zhuk "Rifles and a machine gun!". M. Voennoe izdatelstvo. 1988, pp. 101-102, fig. 76).

The disadvantage of the well-known automatic pistol is the difficulty in operation, as well as significant recoil. To carry out an operation to cock the bolt frame, the shooter needs to remove his hand from the trigger, open the safety, take the bolt by its cocking handle, cock it and turn his hand to the trigger... During these operations, additional time is lost and aiming conditions change by changing the position of the weapon in space .

The closest technical solution, chosen as a prototype, is a submachine gun, which directly contains a barrel, a receiver, a return spring, a bolt with a striker, a magazine, aiming devices located on a casing that has ventilation holes, and in the area of the muzzle made through slit cuts | see description to the declaratory patent for an invention of Ukraine Z 56918А MIZH 7E41А 3/00,20021.

The disadvantage of the well-known submachine gun is the significant force of recoil, as well as the recoil of the barrel when shooting, which requires a significant weight of the weapon and additional devices, as well as the displacement of the center of mass of the weapon is disturbed due to the weight of the bolt, the bulkiness of the weapon due to lower manufacturability. In addition, it is problematic to shoot from narrow gaps.

The invention is based on the task of improving the effectiveness of the weapon by eliminating the shortcomings of the prototype due to reducing the recoil and weight of the weapon, its bulkiness and reducing the time it takes to bring the weapon to combat use.

The essence of the invention of the proposed solution is to create a new design of automatic firearms, for example, a machine gun, a machine gun or other weapons; the gas distribution channel of the barrel has a gas chamber, a piston, a shutter, which rests with its combat stop on the upper part of the lever, and the lower part of the lever rests on its axis, which is fixed in the shock-trigger box, that is, the method of using gases to eliminate recoil is embodied in such a device when shooting

Such a device in weapons allows you to eliminate recoil when firing, reduce the weight of weapons, bulkiness, improve external balance, increase combat accuracy, the mechanism is simplified, and its manufacturability is increased, its production is cheaper and faster... Lighter, high-quality composite materials are more pleasant.

The essence of the invention is explained by drawings; where: figure 1 shows the general appearance of an automatic weapon (weapon version); in fig. 2 - shows the general view of the weapon; in fig. C - shows the second version of the gas chamber; in fig. 4 - the third version of the camera (appendage); in fig. 5 - half gear on the axis of the lever; in fig. 6 - version of the lower part of the toothed lever where the teeth are located on the lever itself from below; in fig. 7 - the option shown from above - traction through the gear to the half gear; in fig. 8 - receiver; in fig. 9 - the rear part of the thrust.

The proposed weapon contains a barrel 1, around which a gas chamber 2 is located. Gas outlet holes are made in the barrel 1. Between the threads in the bore of the barrel, there is a gas chamber 2, where a piston 4 is located, connected by a rod 5 to other parts. At the end of the rod 5, teeth 6 are made for turning the half-gear 7, which is put on the axis of the lever 8, together with the lever 8 is rigidly fixed on this lever 8 in its lower part. It is possible to transfer motion in a straight line from gear 16 to the half gear down (Fig. 7). The recoil spring 9 is located under the barrel 1 and under the thrust 5 in the breech 17. The shutter 10 can be made in the form of a heel 14, in which the backrest 11 goes further back and up behind the curtain 13, which rests against the ceiling of the receiver 18 when the shutter is closed 10, and in the back of the backrest 11 down in the lowest part to the combat stop 19. All this together is located in the rear part of the shutter 10. On the combat stop 19, a small rear thrust 12 is fixed.

A curtain 13 is made on the right side of the shutter. The pin 14 of the shutter 10 has a shortened cylindrical shape and is adapted to the front part of the shutter 10. In cartridges without a sleeve, the curtain 13 is absent, as well as the sleeve window.

A ring or half-ring 20 is installed in the rear end of the curtain, which determines the more practical operation of the shutter when moving it in the receiver 18.

It is possible to install a semi-ring 20, the weight of which is equal to the weight of the curtain 13. Such a semi-ring 20 is necessary for additional correct (correct) direction of the shutter in the receiver box 18. The rear pull 12 of the rear lower part enters the frame 21 of the shutter box 18, where the upper and middle parts of the lever move 8.

The operation of the firearm is carried out from the initial position, when the parts are in their original position: the rear parts (shutter 10, lever 8) are in the city and wait for the movement of the piston 4. When fired, when the bullet passes the piston 10, parts of the powder gases quickly go to the gas holes C in barrel 1. Gases push piston 4 forward. The piston 4 pulls the rod 5, which with its teeth rotates the half-gear 7, with which the lever 8 turns simultaneously, the upper part of which comes out of the combat stop 19 of the shutter 10, frees it and allows it to move back without hindrance. Under the action of the residual pressure, the powder gases equally continue to press on the piston 4 and the shutter 10 in the opposite direction, which eliminates the backward push - a forward jerk and simultaneously squeezes the return-combat spring 9. During the return movement, the spring 9 is unzipped and pushes the parts to the initial position with the force of the spring 9 thrust 5 and lever 8. Under the action of the energy of the spring 9 through the thrust 5 on the lever 8, the bolt 10 pushes the cartridge 22 out of the magazine 23 and sends it into the chamber 24. The mutual movement of the parts of the weapon creates kinetics to each other, at the same time, forces are also not transmitted to the body of the weapon, which allows you to keep it in a calm state without quenching shocks.

The kinetics and kinematics of the movement of the parts of the weapon are interconnected: the parts move in different directions and maintain a balance between them that does not harm each other. The parts of the moving parts are interconnected with each other, mutually reinforcing, that is, the parts that move in different directions maintain balance among themselves, that is, they perfectly maintain the internal balance of the weapon.

Wear and tear of parts is reduced in the proposed design, as there are no moving parts, they have strength and light weight.

The recoil spring 9 is protected from thermal heating from the barrel 1 by the rod 5 and from gases in the tube 25 of the rod 5 from the side of the piston 4. There is no cocking handle on the bolt, which means a slot on the receiver 18, which does not violate the tightness of the weapon and does not cause snags .

To cock the shutter 10 of the system, the fore-end 17 performs a back-and-forth movement, its stroke is short. The weapon is convenient for both right-handed and left-handed shooting. In addition, the shooter's hand is constantly located at the trigger 26, which allows quick firing. The offered weapon is safe from accidental shots. Weapons are possible when changing any capacity of cartridges. The barrel can be smooth-bore or rifled. Modification of weapons and their parts is possible relative to other types of weapons and their merits.

When shooting with a closed shutter 10, the weapon allows firing with a trigger-shock mechanism. But other smoking is possible with a closed shutter 10. The light shutter 10 with its practicality does not involve a violation of the center of mass of the weapon, does not knock down the sights during single shots and is also made by stamping.

The author has no doubts about the implementation of the proposed weapon. shcha / b OO tu i? 4 I 29318 5 in what i
