Description

The invention relates to the current model of weapons, driven by compressed gas, while the appearance of the model corresponds to the appearance of a real small arms, such as a Kalashnikov assault rifle, and coincides with it in overall dimensions.

From US patent No. 5476087 F41B 11/06 (analogue), a technical solution is known under the name "Model of a weapon with a mechanism for automatically feeding a bullet," running on gas and copying the appearance of a combat pistol.

The specified model contains a barrel, a receiver (frame), a bolt, a trigger, a trigger, a separate automatic unit inserted into the handle of a gun. The detachable unit is made with two sealed compartments, one of which serves as a magazine for placing and supplying bullets with a spring-loaded feeder, and the other compartment serves as a reservoir for liquefied or compressed gas. The detachable unit further comprises a valve system with a seal and a controller that controls the flow of gas, together providing a cut-off of a portion of the gas, the ejection of a bullet through the bore, moving the shutter and other intermediate parts.

Gas recharging and magazine equipment bullets (balls) is carried out when removing the unit from the product. After loading the magazine with bullets, the block is installed in the same place in the pistol grip and fixed. The bullet is fed into the barrel channel by a spring-loaded bullet feeder, which raises the bullet to the top of the magazine, and sequentially moves the shutter under the action of a portion of compressed gas controlled by the controller, sends the bullet to the barrel channel. When the trigger is exposed to a trigger, a bullet leaves the bore channel under the action of another portion of gas - a shot occurs.

The disadvantages of the known model of weapons are:

- increased consumption of compressed gas, complexity and unreliability in operation due to the cost of a portion of gas to move significant masses and the presence of a large number of intermediate parts;

- the possibility of a random shot in the process of equipping the store with bullets.

From the patent information, the invention is known, registered under the name "Gas Ballistic Multiply Charged Weapon", copying the appearance of the combat machine, patent RU No. 2154792 C1 F41B 11/02 (prototype).

The known model of weapons according to patent RU No. 2154792 contains a barrel with a receiver, a trigger, a casing, a detachable unit, referred to as a "detachable store", which contains a housing with two compartments and a spring-loaded trigger fixed to the housing. One of the compartments - the drive - contains a bullet feed mechanism, including a spring-loaded feeder. Another compartment contains a valve system with seals, a gas reservoir (can), a mechanism for preloading and tipping the can in the form of a screw and a needle.

According to the invention according to the patent RU No. 2154792 for charging with gas and equipment of the detachable unit of the "detachable store" it must be disassembled, separating the housing from the casing. The gas tank (spray can) is installed in the housing, tighten the screw to the needle and pierce the membrane of the spray can. The feeder of the bullet feed mechanism is forcibly lowered to overcome the force of the spring, and through the outlet, which is also loading, load bullets (balls) into the drive. Then the feeder is released, which, under the action of the spring, compresses the bullets (balls) to the top of the drive. The equipped block is installed in the casing, fixed with a latch and the casing is inserted into the receiver window. The product is ready to fire.

This technical solution was used in the design of the product "valve gas cylinder unit", manufactured and sold as a separate unit by the manufacturer.

The disadvantages of the technical solution (prototype) identified in practice during its operation are:

- the danger of an accidental shot, spontaneous ejection of bullets (balls) when equipping and reloading a magazine (storage), is higher than that of an analogue, see US Pat. , located on the body of the detachable unit;

- contamination of the sealing elements of the valve system when the detachable unit is outside the weapon, which leads to gas leakage during operation of the product, lower initial bullet speed, shot instability.

The invention is aimed at eliminating the identified disadvantages of the prototype and improving the reliability of the mechanisms and products as a whole.

The objective of the invention is to create a model of weapons that provides a technical result (a number of results):

- the exception of spontaneous bullet departure when the magazine / magazine is equipped due to the drive being detachable and independent of the gas device;

- prevention of contamination of the valve system due to the placement of the gas-balloon device in a separate housing, mounted on the product itself (weapon model);

- prevention of gas leakage and ensuring a reliable bullet escape due to the forced pressing of the drive through the seal to the breech of the barrel and contacting the drive with the breech on the conical surfaces;

- prevention of gas leakage when the tank with gas (canister) is punctured due to the preliminary regulation and speed of puncture of the canister membrane using a lever mechanism.

To achieve this goal, a model of small arms, made in the form of gas-balloon weapons, contains essential features similar to the prototype:

- trunk;

- receiver;

- trigger;

- trigger;

- a casing in which the magazine is fixed, including a bullet drive with a feed mechanism;

- gas-balloon device, comprising a valve system, a tank with gas;

- the mechanism of preloading and tipping the tank;

and new distinctive salient features:

- the aforementioned bullet drive with a feed mechanism made detachable and secured in the casing with the possibility of forced compression to the breech of the barrel and contact with it;

- gas-balloon device is made in the form of a single assembly placed in a housing fixed in the receiver with the possibility of rotation and interaction with the casing and bullet storage. In addition, the body of the gas-balloon device is fixed in the receiver by means of spring-loaded pins, is spring-loaded relative to the receiver and is equipped with an o-ring, which compresses the bullet accumulator to the breech of the barrel;

- the bullet magazine is in contact with the breech on the conical surfaces and secured in the casing with a spring-loaded latch;

- the mechanism of preloading and tipping the tank is made in the form of a base equipped with an adjustment element and installed in the body of the gas-balloon device with the possibility of fixed movement.
