Description

The utility model relates to hand-held portable firearms and is intended for use by civilians for self-defense by firing traumatic elements or giving sound and light signals (flashes when fired).

State of the art

The creation of civilian weapons for self-defense requires the fulfillment of a number of requirements. The specific energy limit (the ratio between energy and the cross-sectional area of the bullet) must be maintained in order to exclude the possibility of causing serious bodily harm. In this case, the total energy level should be sufficient to achieve the effect of the stopping action of the weapon. The stopping effect is characterized by the ability to transfer a certain amount of kinetic energy to an obstacle with a minimum penetration depth. The action of self-defense weapons should not lead to serious bodily harm or injury, and the weapon itself should exclude the possibility of its criminal use for its intended purpose.

Civil self-defense weapons are known - the so-called "gas" weapons: gas pistols or revolvers and cartridges for them.

The appearance, dimensions, design of the main mechanisms and the caliber of the cartridges used for such weapons are usually consistent with military ones, that is, they are copies of military weapons by design. The cartridges for such weapons do not contain bullets, and the shell equipment consists of a mixture of smoke powder and any active substance. Cartridge shells are equipped with shock-ignition capsules. In order to prevent the use of live ammunition in such weapons, various constructive methods are used. For example, these problems are solved by manufacturing the barrel and other parts from a material that has a known lower strength, which can lead to rupture of the barrel from the pressure of the powder gases when fired by a live cartridge. To establish the possibility of criminal use also shift the axis of the chamber

and the barrel channel or install in the barrel channel a solid jumper (without completely blocking the bore) made of hard alloy or cermet. Nevertheless, the possibility of the criminal use of such weapons with the use of live ammunition is not excluded. Widely known cases of alteration of such weapons, due to its availability.

Known weapons of self-defense (see RF patent No. 2079087 Cl, F 41 C 3/00, 05/10/1997) containing a barrel or trunks made in the form of cartridges.

This device has a significant drawback - the presence of a bulky trigger mechanism. The large dimensions and mass of the trigger mechanism are largely determined by the need to perform an additional function, such as the distribution of strikes of the striker (main) in the peripheral strikers, which in turn requires the installation of additional kinematically connected massive parts into the trigger mechanism.

As a prototype, a weapon of self-defense was selected (see RF patent No. 2172460 Cl, F 41 C 3/00, 08/20/2001), containing a housing, a handle, a trigger and a trigger mechanism. This device has disadvantages - difficulty aiming, complex electrical circuitry, large mass, strong recoil (impact on the rear surface of the weapon).

As the closest analogue for the guide, you can choose any weapon, for example, a weapon of self-defense (see RF patent No. 2172460 Cl, P 41 C 3/00, 08/20/2001), containing a guide for the bullet, made in the form of a cartridge case. This device has disadvantages - the small length of the sleeve, which affects the shooting - the difficulty of aiming.

Disclosure of a utility model.

The objective of this utility model is to eliminate the shortcomings of the prototype and create an effective and reliable self-defense weapon that looks similar to a combat one (having a guide for a bullet that looks similar to a barrel), with low recoil, an improved aiming system and the possibility of its criminal use using combat cartridges, as well as after an affordable alteration in domestic conditions.

This problem is solved in that in a self-defense weapon containing a housing, a handle, a trigger and an actuation mechanism, further comprises

magazine for cartridges and a guide for the bullet, in which through its grooves are made through the grooves.

The self-defense weapon may have an actuation mechanism comprising a pulsed magnetoelectric and / or electrochemical current source electrically connected to a switchgear comprising a contact assembly.

Self-defense weapons may have a mechanism for actuating a mechanical type.

Self-defense weapons may include a laser target designator.

Self-defense weapons may contain a laser device to blind the enemy.

Through grooves can be made in a spiral line relative to the axis of the guide

Also claimed is the guide for the bullet, which contains through holes and / or grooves, which in turn have a total surface area, which eliminates the increase in the speed of the bullet when it moves along the guide.

A comparative analysis of the proposed solution with the prototype and other technical solutions in the art shows that it contains a magazine for cartridges and a guide for the bullet, in which through grooves are made along its axis. Performing weapons with a magazine allowed to increase the ammunition load of weapons. The implementation of the guide for the bullet, in which through the grooves are made along its axis, made it possible to increase the accuracy of aiming, while the bullet does not accelerate, but only stabilizes when it is flying, which makes it possible to use this self-defense system as barrelless. The whole set of features allows you to create an effective weapon of self-defense, while completely eliminating the possibility of direct criminal use of this means of self-defense. At the same time, a general energy level is achieved to achieve a stopping action, but the specific energy limitation is also preserved.

In the claimed guide for the bullet, through holes and / or grooves are made, which have a total surface area that eliminates the increase in the speed of the bullet when it moves along the guide, which allows the use of this invention in barrelless weapon systems and eliminates the possibility of criminal use of such weapons.

A brief description of the drawings. Figure 1 presents a General view of the weapon of self-defense.

Self-defense weapons consist of the following main components and parts:

1. Case;

2. Guide for the bullet;

3. The handle;

4. Shop;

5. Cartridge;

6. Groove;

7. Trigger (trigger);

8. Pulse generator

9. Contact node;

10. Laser target designator (LC).

An embodiment of a utility model.

This embodiment is only a special case of the device.

The weapon consists of a housing 1, a guide for a bullet 2, a handle 3, in which there is a magazine 4 with cartridges 5 (the cartridges of which serve as mini-barrels of this self-defense weapon). A through groove 6 is made on the guide for the bullet 2, which can be parallel or helical (made in a spiral) relative to the axis of the guide 2. Instead of a through groove 6 on the guide for the bullet 2, through holes (not shown) can be made. Their number (the total surface area of the grooves and / or holes) is selected from the condition under which the increase in the velocity of the bullet when it moves along the guide 2 is excluded. In the housing 1 there is a driving mechanism, which can be mechanical, electrical or mixed type. In this weapon, an electric type driving mechanism is used. It consists of a trigger 7, which is connected to a pulse generator of electric current 8, the pulse from which is supplied to the contact node 9, which in turn initiates an electric igniter cartridge 5. In front of the weapon of self-defense, under the guide 2, a laser designator 10, which facilitates aiming, especially in the dark. In addition, LC 10 can be combined with a laser device to blind the enemy.

The actuation mechanism may be of a mechanical type. In this case, instead of the contact node 9 there will be a striker connected to the trigger 7 by means of mechanical connection. In this case, cartridges 5 with an impact igniter capsule will be used.

The weapon works as follows. In the handle 3, a magazine 4 is inserted with cartridges 5 consisting of a cartridge case with an electric igniter or shock capsule-igniter, a propelling charge and a missile body (pyrotechnic signal element, rubber bullet, light-sound element), and press the start key 7. Before shooting, you can turn on if necessary laser target designator 10. In the dark, the LC 10 is a convenient means of conducting targeted shooting.

The production of the shot is as follows. When you press the start key 7, the movement from the key is transmitted to a pulsed electric current generator 8. A working pulse is issued to trigger the electric igniter of the first cartridge with standard electrical resistance. A shot is taking place. A bullet accelerating in a sleeve continues to move along the guide 2. Since through grooves and / or holes are made in the guide 2, then the bullet does not accelerate when moving along it (as it should have happened in the barrel), but only stabilizes its direction and the shot is more accurate than in other barrelless self-defense systems. After the shot, the spent cartridge is extracted, and a new cartridge is fed into its place from the magazine 4.

To produce the next shot, the start key 5 is returned to its original position and pressed again.

With subsequent presses, the remaining cartridges are triggered alternately.

To reload weapons, separate magazine 4 and insert a new one. Industrial applicability.

The implementation of the weapon with a guide for the bullet in which through grooves and / or holes are made allowed to create an effective self-defense weapon that looks similar to a combat one, with low recoil, an improved aiming system and the possibility of its criminal use (the possibility of increasing the damaging factor).
