Abstract

 1. Cartridge for barrelless weapons, containing a sleeve, a primer, a powder charge and a bullet, characterized in that the sleeve is made of collapsible and consists of two parts: a reusable part, which ensures the strength of the sleeve, and a disposable part that combines the primer , a powder charge and a bullet and fully or partially placed in the reusable part of the sleeve with the possibility of axial fixation. ! 2. The cartridge according to claim 1, characterized in that the disposable part of the sleeve is made of a polymeric material and has an acceleration section for communicating the forward movement of the pool and rifling for imparting rotational movement to the pool.

Description

The utility model relates to cartridges for barrelless self-defense weapons.

Known traumatic cartridge for barrelless self-defense weapons, containing a sleeve of polymer material, an additional housing, a powder charge, an igniter capsule and a bullet with a metal core (patent for PM No. 57444 of May 17, 2006).

Also known is a traumatic cartridge for barrelless weapons containing a sleeve, an igniter, a powder charge and a traumatic element in the form of an elastic bullet with a metal core (patent RU No. 2179700 dated April 13, 2001).

A common disadvantage of both cartridges is their high cost, due, in particular, to the complexity and high complexity of the manufacture of liners. The cartridge case for barrelless weapons, in addition to its main function - combining the capsule, gunpowder and bullet into one assembly, also serves as a disposable barrel. It should have the necessary strength and provide directional flight of the bullet.

The purpose of the utility model is to reduce the cost of the cartridge.

This goal is achieved by the fact that in a cartridge for barrelless weapons containing a sleeve, an igniter capsule, a powder charge and a bullet, the cartridge case is collapsible and consists of two parts: a reusable part that provides the strength of the cartridge case and a disposable unit that combines the igniter capsule into a single unit , a powder charge and a bullet and placed in a reusable part of the sleeve with the possibility of axial fixation. The disposable portion of the sleeve is made of polymeric material and has an acceleration section for communicating the forward movement of the bullet and grooves for imparting rotational motion to the bullet.

With this design, the cost of the cartridge is reduced due to the exclusion from its composition of an expensive disposable sleeve that performs the functions of the barrel in terms of ensuring the strength of the sleeve. In the proposed solution, the strength of the sleeve is provided by its metal reusable part, and the combination of the cartridge components into one and giving the bullet directional movement provides a cheap polymer disposable part of the sleeve. The disposable portion of the sleeve may be housed in the reusable portion in whole or in part. The reusable part of the sleeve can be made in the form of one part or at least two parts. An individual number may be marked on the reusable part of the sleeve. The igniter capsule may be an impact or electric type. The reusable part of the sleeve is made of non-ferrous metal or stainless steel if used in an electric cartridge. The disposable part of the sleeve can be combined into one whole throwable equipment for various purposes, for example, signal, noise, light and sound, etc.

The figure shows a sectional view of a General view of the cartridge for barrelless weapons of 18x45 caliber as an embodiment of the utility model.

The cartridge sleeve consists of a durable reusable part 1 and a polymer disposable part 2, in which an electric capsule 3, a powder charge 4 and a bullet 5 are mounted. The reusable part 1 and the disposable part 2 are interconnected by a thread (not shown), which ensures their mutual axial fixation.

The user of the barrelless weapon acquires the minimum required number of reusable parts 1 and cheap disposable parts 2. Inserts the disposable part 2 into the reusable part 1 and twists them all the way, while providing electrical contact between the reusable part 1 and the electrocapsule 3 (not shown). The cartridge is ready to fire from all existing models of barrelless weapons.

The single-shot shooting part 2 is removed from the reusable part 1 and replaced with a new one. The resource of the reusable part of the sleeve must be at least the resource of the weapon itself.

The utility model can significantly reduce the cost of a shot from barrelless self-defense weapons.
