Description

The utility model relates to pneumatic weapons that can be used both for shooting bullets and for shooting low-impulse cartridges that are triggered by the impact of a bullet.

The prototype is a multifunctional pneumatic weapon (RU 2231730, IPC F41B11/00, published on 27.06.2004), comprising a housing and a barrel with a bore. An open chamber is mounted in the front part of the housing coaxially with the barrel bore in front of its muzzle. The open chamber is designed with the possibility of alternately feeding low-impulse cartridges (hereinafter referred to as cartridges) into it. The open chamber may contain a mechanism that prevents the cartridge from falling out prematurely.

A disadvantage of the known weapon is its reduced safety indicators. When the muzzle is closed by a low-impulse cartridge, the bullet in the barrel will work as a piston, creating an excess pressure zone in the barrel. That is, the movement of the bullet will cause compression of the gas in the barrel in front of it, which will push the cartridge out of the chamber. In this case, the bullet flying out of the barrel may not hit the center of the cartridge, which will cause an unpredictable trajectory of the charge.

When using an open chamber with a mechanism that prevents the cartridge from falling out prematurely, there is a high probability of the weapon not firing. When the muzzle is closed, the bullet, as it moves along the barrel, compresses the gas in the barrel in front of the bullet. When the pressure in the sections of the barrel before and after the bullet equalizes, the bullet will stop before reaching the cartridge, and the low-impulse cartridge will not be activated.

The objective of the utility model is to improve the operational characteristics of weapons.

The technical result consists in increasing the safety of a multifunctional pneumatic weapon when used together with a low-impulse cartridge by creating a stable, predictable charge trajectory by preventing the possibility of the cartridge shifting relative to the barrel bore at the moment the bullet hits the cartridge cap, while ensuring the operability of the multifunctional pneumatic weapon, in which the bullet moves freely along the barrel bore.

The stated task is solved due to the fact that the multifunctional pneumatic weapon contains a barrel with a bore and is made with the possibility of installing a low-impulse cartridge coaxially to the bore, in which, according to the utility model, the muzzle part of the bore is made with the possibility of compensating for excess pressure and contains a fastening means made with the possibility of forming a detachable connection. The fastening means can be made in the form of a thread. An expansion chamber can be made in the muzzle part of the bore.

For the declared weapon, various types of low-impulse cartridges (hereinafter referred to as cartridges) such as gas, noise, light, for example, threaded cartridges "Signal Hunter", "Thunder", etc. can be used. Also, the declared weapon can be used together with a part that on one side contains a socket for installing a cartridge or charge, and on the other - a means of fastening to form a detachable connection with the declared weapon.

Below we will consider an example of a weapon designed for use with the signal threaded cartridge "Signal Hunter".

The essence of the utility model is explained by the following drawings.

Fig. 1 - partial view of a weapon with an expansion chamber in the muzzle of the barrel bore;

Fig. 2 - partial view of the weapon with a bleed hole in the muzzle of the barrel bore;

Fig. 3 - partial view of the weapon assembled with a cartridge.

The multifunctional pneumatic weapon comprises a barrel 1 with a channel 2 (Fig. 1, 2, 3). The muzzle part of the channel 2 of the barrel on the side of the muzzle cut contains a fastening means for forming a detachable connection with a cartridge 3, which is made in the form of a thread 4. The muzzle part of the channel 2 of the barrel is made with the possibility of compensating for excess pressure.

Fig. 1, 2 show embodiments of the muzzle part of the barrel bore 2 for compensating for excess pressure. Fig. 1 shows an embodiment of the muzzle part of the barrel bore 2 with an expansion chamber 5. Fig. 2 shows an embodiment of the muzzle part of the barrel bore 2 with a bleed hole 6. All the above-mentioned embodiments of the muzzle part of the barrel bore are located before the fastening means.

The threaded cartridge “Hunter’s Signal” for use with the considered version of the declared weapon contains a body 7 with a thread for connection with a barrel 1, a primer 8 and a charge 9 (Fig. 3).

The presence of a means of fastening for connection with a cartridge in the muzzle of channel 2 of the barrel allows the cartridge to be securely fastened coaxially with channel 2 of the barrel and thereby ensure the impact of the bullet in the center of the cartridge and a stable, predictable flight trajectory of the charge.

The implementation of the fastening means in the form of a detachable joint enables the declared weapon to perform the function of both a pneumatic and a signal and/or noise, gas, etc. weapon. The implementation of the fastening means for forming a detachable joint can be made in response to the fastening means provided for by the design of the device with which the declared weapon is supposed to be used, for example, a thread. Nevertheless, the fastening means can be universal and not depend on the fastening means of the cartridge. In particular, the fastening means can be implemented in the form of a flexible shock-absorbing element installed in the muzzle of the barrel, which forms a connection with the cartridge due to friction forces. Such an element can be, for example, a spring or an insert made of an elastic material.

The implementation of the muzzle part of the 2nd barrel channel with the ability to compensate for excess pressure prevents the occurrence of the effect when a bullet with a closed muzzle stops in the barrel before reaching the cartridge.

The design variant of the muzzle part of the channel 2 of the barrel for compensating excess pressure is selected depending on the technological capabilities of production. The volume of the expansion chamber 5 and the diameter of the bleed hole 6 are selected sufficient to prevent the occurrence of the effect when the bullet with a closed muzzle stops in the barrel without reaching the cartridge.

The operation of the declared weapon will be further considered using the example of the execution of the muzzle part of the barrel bore with an expansion chamber 5 (Fig. 2, 3).

The weapon works as follows.

If it is necessary to use the declared multifunctional pneumatic weapon as a signal weapon, the signal cartridge 3 is installed using the threaded connection 4 in the bore 2 of the barrel. Then the trigger (not shown) is pressed and a shot is fired. After that, the bullet (not shown) begins to move along the bore 2 of the barrel, compressing the gas in front of it, part of which goes into the expansion chamber 5, which eliminates the possibility of excess pressure in the bore 2 of the barrel. As a result, the bullet passes freely along the bore of the barrel and strikes the center of the cartridge 3 on the cap 8. The cap 8 is activated, ignited and the charge 9 flies out. For further use of the weapon, it is necessary to disconnect the body 7 of the cartridge from the weapon and remove the bullet from the bore 2 of the barrel. To remove the bullet from the bore 2 of the barrel, the weapon is tilted, directing the muzzle cut downwards until the bullet falls out on its own. The weapon is ready for further use.

The claimed utility model allows for the creation of a safe multifunctional pneumatic weapon, in which the bullet's hit in the center of the cartridge is guaranteed by fixing the cartridge's position relative to the barrel bore by means of a detachable connection, and the bullet has the ability to freely move along the barrel bore and reach the cartridge's cap due to the muzzle part of the barrel bore being made with the ability to compensate for excess pressure.
