Description

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

 The creation of civilian weapons for self-defense requires the fulfillment of a number of requirements. First, the specific energy restriction (the ratio between energy and bullet cross-sectional area) must be maintained. This value should be less than or equal to 0.5 J / mm, since with a larger value it can cause serious bodily harm. In this case, the overall energy level should be quite high (~ 100 J), otherwise the effect of the stopping action of the weapon will not be achieved. The stopping action 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, mutilation, 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 used cartridges of 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 cartridge case equipment consists of a mixture of smoke powder and any active substance. Cartridge sleeves are equipped with shock-ignition capsules. In order to prevent the use of live ammunition in such weapons, various design 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 a rupture of the barrel from the pressure of the powder gases when fired with a live cartridge. To establish the possibility of criminal use, the axis of the chamber and the bore is also shifted, or a strong bridge (without completely blocking the bore) is made of a hard alloy or cermet in the bore. Nevertheless, the possibility of the criminal use of such weapons with the use of live ammunition is not excluded. Cases of alteration of such weapons due to its availability are widely known.

 Weapons are also known whose cartridges are powered by electric current. Basically, such constructive solutions are used in large-caliber weapons, mounted mainly on aircraft and ships. For example, aviation cartridges for signal cartridges and cartridges of various kinds of interference.

 In portable small arms, electrical methods for engaging cartridges have not been used.

 A known solution to the use of the electric method of firing in small arms (see US patent N 3854231, F 41 C 19/12, 12/17/1974). The patent describes a weapon that uses cartridges consisting of a large number of consecutively located and sequentially fired charges.

 In this case, the electric method was applied in order to ensure consistent ejection of charges, which would be extremely difficult to implement with the use of percussion igniter caps.

 A device was selected as a prototype (see RF patent N 2079087 C1, F 41 C 3/00, 05/10/1997), from which a self-defense weapon containing a barrel or trunks made in the form of cartridge cases is known.

 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) over the peripheral strikers, which in turn requires the installation of additional, kinematically connected massive parts into the trigger mechanism.

 The objective of the present invention is the creation of an effective and reliable weapon of self-defense, eliminating the possibility of direct criminal use with the use of live ammunition, as well as after an affordable alteration in domestic conditions.

 This problem is solved in that in a self-defense weapon containing an ammunition holder, the barrels are made in the form of cartridge cases with an electric igniter, and the actuation mechanism contains a pulsed magnetoelectric or electrochemical current source electrically connected to a switchgear containing a contact block.

 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 a barrel made in the form of a cartridge sleeve with an electric igniter and an actuation mechanism. This made it possible to completely exclude 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 effect, but the specific energy limitation is also preserved. The total speed of the bullet cannot be increased to more than 150 m / s (the speed of the bullet for causing serious bodily harm should be 180-200 m / s). In addition, electric igniters are not commercially available, and strict production is carried out during their production.

 In the declared self-defense weapon, the implementation of the actuation mechanism with a source of electric current eliminates the possibility of its criminal use, since all live ammunition of small arms are equipped with shock-ignition capsules.

 To ensure a shot with a special cartridge, the weapon is equipped with a switchgear (switching mechanism), providing a given sequence of shots and indexing of the fired barrel.

 In FIG. 1 shows a general view of self-defense weapons.

 In FIG. 2 is a front view.

 In FIG. 3 shows an embodiment of a weapon with one cartridge case.

 The weapon consists of four cartridge sleeves 1 with an electric igniter 2 installed in the housing 3. An electric current source 5 and a switchgear (switching mechanism) 6 are installed in the handle 4. A mechanical magnetoelectric pulse generator is used as an electric current source. It is possible to use other current sources, for example, electrochemical (batteries). Cartridge sleeves are held in the housings and pressed to the contacts 7 by spring elements. The contact block is made in the form of a separate assembly, which is fixedly mounted in the handle. The switching mechanism is controlled by a start key via the rod, while the current generator button is also controlled by the start key.

 The weapon works as follows. One or more cartridges consisting of a cartridge case with an electric igniter, a propellant charge and a missile body (signal pyrotechnic element, rubber bullet, light-sound element) are inserted into the weapon body, and the shutter button is pressed.

 When pressed, the pusher of the switchgear moves (that is, the (channels) of contacts in the contact group are switched) and the button of the current generator moves, which is triggered by the further movement of the key. The current pulse passes through the switch to the corresponding contact and electric igniter. The cartridge fires.

 Subsequent presses will alternately trigger the remaining cartridges.

 The work of self-defense weapons, when the cartridge is made with one socket, occurs similarly.

 The execution of the barrel in the form of a cartridge case with an electric igniter and the use of an electric current source to drive into action made it possible to create an effective weapon of self-defense, excluding the possibility of its criminal use for its intended purpose (the possibility of increasing the damaging factor).

Claims (1)

 Self-defense weapon containing a cartridge holder, barrels made in the form of cartridge cases and an actuation mechanism, characterized in that the cartridge cases are electrically ignited, and the actuation mechanism comprises a pulsed magnetoelectric or electrochemical current source electrically connected to a switchgear, containing the contact block.
