The objective of this technical solution is to simplify the design of the cartridge and expand its functionality. The indicated problem for a traumatic cartridge for a self-defense weapon is solved in that it contains a sleeve, a powder charge, an igniter capsule and a traumatic element made in the form of a bullet, while a hole is made in the bottom of the bullet, the powder charge and an igniter capsule are made in the form of a blank cartridge, which is located at the bottom of the sleeve with its bottom part, and the muzzle and / or housing of the empty cartridge are partially or completely placed in the hole of the bullet.

Description

The technical solution relates to cartridges for handguns of self-defense (non-lethal weapons), which are intended for use by civilians for self-defense by firing traumatic elements to repel an attack due to pain, causing a shock condition.

State of the art

Known cartridge for firearms (RU 2103646 C1, F 42 B5 / 02, 01/27/1998), containing a sleeve compressed at the front end, an igniter capsule, a propelling charge and a missile body - a bullet.

The disadvantages of this cartridge is that the bullets are metal and are designed for penetrating wounds.

As the closest analogue, a traumatic cartridge was chosen for a barrelless weapon containing a sleeve with screw protrusions on the inner side of the wall from the cut side, an ignition element, obturation means, a powder (throwing) charge and a traumatic deforming shock element in the chamber of the sleeve (see patent RF No. 2079087 C1, F 41 C 3/00, 05/10/1997).

This cartridge has the following significant disadvantages - the complexity of the design, the possibility of alteration of the cartridge in order to increase the weight of gunpowder and insufficient stopping effect.

Disclosure of a technical solution.

The objective of this technical solution is to simplify the design of the cartridge and expand its functionality.

The technical result is to simplify the design of the cartridge, expanding its functionality and eliminating the possibility of direct criminal use and causing grievous bodily harm at a distance of 1.0 m and guaranteeing a stop (pain) effect at a distance of up to 20 m.

The indicated problem for a traumatic cartridge for a self-defense weapon is solved in that it contains a sleeve, a powder charge, an igniter capsule and a traumatic element made in the form of a bullet, while a hole is made in the bottom of the bullet, the powder charge and an igniter capsule are made in the form of a blank cartridge, which is located at the bottom of the sleeve with its bottom part, and the muzzle and / or housing of the empty cartridge are partially or completely placed in the hole of the bullet.

The bullet may be made of metal or a metal alloy with the possibility of covering its outer surface with elastic material.

Grooves, like Revelli grooves, can be made on the surface of a bullet hole.

The grooves can be made in a spiral line relative to the axis of the cartridge to give the bullet rotational motion.

On the inner surface of the liner can be made protrusions preventing the departure of the drink until the moment the force pressure is reached.

An additional powder charge may be located in the bullet hole.

The igniter capsule may be electric.

The cartridge sleeve may be made of a polymeric material.

The cartridge sleeve can be placed in an additional housing with the possibility of fixation from mutual axial movement

A comparative analysis of the proposed solution with the prototype and other technical solutions in this technical field shows that the claimed solution differs in the use of a blank cartridge for throwing a bullet and the metal bullet with the possibility of covering it with elastic material, which significantly simplified the design of the traumatic cartridge, since it does not require special the igniter capsule with a powder charge, and the forcing pressure is created by pressing the blank cartridge sleeve to the inner surface spine hole formed in the pool. Using

a single cartridge with an electric or shock igniter capsule has expanded the functionality of the cartridge.

In order to exclude the possibility of overloading the cartridge, the sleeve is made of polymer material, which will become worthless when trying to reload the cartridge.

A brief description of the drawings.

Figure 1 presents a General view of the traumatic cartridge.

An embodiment of a technical solution.

The design of the traumatic cartridge for self-defense weapons (Fig. 1) includes a sleeve (1) made of polymer material, a blank cartridge (2), with an electric igniter capsule (3), a powder charge (4) placed in a blank cartridge and a traumatic element (bullet) (5), which can be covered with elastic materials (6), for example, rubber, which serves to reduce the likelihood of causing serious bodily harm. On the sleeve (1) can be made protrusions (7) to prevent overloading of the cartridge, as well as to ensure the creation of the necessary pressure in the hole (8) of the bullet. To eliminate the possibility of destruction, the cartridge sleeve (1) can be placed in an additional housing (9) with the possibility of fixation from mutual axial movement, for example, by means of protrusions (10).

The cartridge sleeve (1) simultaneously serves as a barrel and must withstand a pressure of more than three times the pressure of the powder gases during firing, for which it is made of high-strength polymer.

The traumatic element (bullet) (5) is made of metal or a metal alloy. Outside, it is covered with hard rubber (6), which repeats the shape of a bullet. Grooves (11) can be made on the surface of the bullet hole (8), for example, in a spiral. They serve to create the necessary pressure forcing inside the cartridge case during the initiation of a blank cartridge (2).

An additional powder charge may be located in the hole (8) to increase the range of the bullet.

Traumatic cartridge works as follows. When an electric igniter capsule (3) is activated (there may be an impact type of action) from an external pulsed current source, an incandescent bridge (not shown) ignites a sample of the powder charge (4) in the housing of the empty cartridge (2). Upon reaching a critical value of the pressure of the powder gases, the blank cartridge (2) opens and the powder gases break out into the cavity in the pool, where, interacting with the inner surface of the bullet and the grooves (11) they give the pool (5) the necessary acceleration and rotation. The blank cartridge (2) is pressed into the bottom of the cartridge case (1) and remains inside. Thus, the bullet can reach (5) with the necessary parameters.

The caliber of the bullet, its mass, kinetic energy are selected in such a way as to exclude the infliction of grievous bodily harm at a distance of 1.0 m and guarantee a stopping (pain) effect at a distance of up to 20 m. The average speed of a bullet of a traumatic cartridge when firing at a distance of 1 m from the cut of the sleeve is (120 ± 10) m / s and is provided by the selection of a blank cartridge.

Industrial applicability.

This cartridge with the claimed bullet was tested and excluded the infliction of grievous bodily harm at a distance of 1.0 m and guarantee a stopping effect at a distance of up to 20 m.The implementation of the cartridge case with a blank cartridge allowed it to be used as a self-defense weapon, eliminating the possibility of its criminal use.
