RU2369824C1 - Noiseless arms - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention is related to noiseless arms of shooting, grenade-launching and mine-launching types. Arms comprise box, trigger mechanism and four blocks, which are connected by single string to projectile. At the same time front and back blocks are installed in pairs in two carriages with the possibility of displacement along box in opposite directions with the help of power element, based on powder, pneumatic or elastic base.

EFFECT: higher efficiency of arms.

Description

Purpose of the invention

The invention relates to small arms, grenade and mortar weapons.

Prior art

Known silent weapons (patent RU No. 2275577 C1. Silent weapons) containing a bed, trigger mechanism, a combustion chamber, two cylinders and four blocks connected by one bowstring to a projectile.

The lack of prototype

However, the prototype, dispersing each block with a separate piston, is not effective enough. Moreover, the parasitic volume in the form of a combustion chamber perpendicular to the bed further slows down the operation of the device.

Disclosure of invention

In order to eliminate the aforementioned shortcomings, the silent weapon contains a bed, a trigger mechanism, and four blocks connected by one bowstring to a projectile. In this case, the front and rear blocks are mounted in pairs on two carriages with the possibility of moving along the bed in opposite directions with the help of a power element based on a powder, pneumatic or elastic basis. On each of the carriages, two additional blocks can be installed.

The proposed technical solution is illustrated by figa, figb and fig.2, where 1 is a bed, 2 is a block, 3 is a carriage, 4 is a bowstring, 5 is a shell, 6 is a cylinder, 7 is a piston, 8 is a powder or pneumatic charge, 9 - spring, 10 - butt, 11 - bowstop travel limiter and 12 - carriage travel limiter.

The work of invention

The device operates as follows.

When you press the trigger of the carriage 3 (using a charge of 8 or a spring 9 of the expanding pistons 7) they accelerate in opposite directions, pushing the projectile 5 by the string 4, connected with the blocks 2 installed on these carriages. When fired, the projectile’s exit speed is four times that of the carriage. The carriage 3 (together with the piston 7) can be stopped using the stroke limiter of the carriage 12 with a shock absorber, and the stroke limiter of the bowstring 11, also equipped with a shock absorber. In this case, the pistons 7 should not come out of engagement with the cylinder 6.

In the pneumatic version, the device can operate in two ways:

- either excess air pressure between the cylinders 6 is created previously (in this case, the trigger is wound on a bowstring);

- or, as in the case of a powder charge, the trigger mechanism is used.

On figa and 1b shows a silent weapon according to paragraph 2 of the claims, figure 2 - according to paragraph 3 of the claims.

Blocks 2 can be located both horizontally and vertically. When the vertical arrangement of blocks 2 bowstring 4 when fired, stops the stroke limiter bowstring 11.

By doubling the number of blocks 2 on carriages 3, the reduction coefficient of the pulley mechanism increases from four to eight times, i.e. the speed of the projectile 5 compared with the speed of the piston 7 increases eight times. This is important, because the pistons 7 at low speeds to stop easier.

Claims (4)

1. Silent weapon containing a bed, a trigger and four blocks connected by one bowstring with a missile projectile, characterized in that the front and rear blocks are mounted in pairs on two carriages with the possibility of moving along the bed in opposite directions using a power element. 2. The device according to claim 1, characterized in that the power element is made in the form of a cylinder with two pistons and a powder or pneumatic charge located between them. 3. The device according to claim 1, characterized in that the power element is made elastic. 4. The device according to claim 1, characterized in that on each carriage two additional blocks are installed, while all eight blocks are connected by one bowstring to a missile projectile.
