Description

 The invention 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).

 The creation of civilian weapons for self-defense requires the fulfillment of a number of requirements. The specific energy limit (the ratio between the 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 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 or injury, and the weapon itself should exclude the possibility of its criminal use for its intended purpose.

 The civilian self-defense weapon, the so-called gas weapon, is known: 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 by 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.

 Known weapons of self-defense (see RF patent 2079087 C1, 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 self-defense weapon was selected (see RF patent 2172460 Cl, F 41 C 3/00, 08/20/2001), containing a cartridge holder with sockets, barrels made in the form of cartridge cases with an electric igniter, and an actuating mechanism containing a pulse a magnetoelectric and / or electrochemical current source electrically connected to a switchgear comprising a block of contact nodes.

 This device has disadvantages - difficulty aiming, complex electrical circuitry, large mass, strong recoil (impact on the rear surface of the weapon).

 The objective of the present invention is to eliminate the disadvantages of the prototype and the creation of an effective and reliable weapon of self-defense, eliminating the possibility of direct criminal use with 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 with sockets, barrels made in the form of cartridge cases with an electric igniter and an actuation mechanism containing a pulsed magnetoelectric and / or electrochemical current source electrically connected to a switchgear containing a unit contact nodes. The contact nodes of the unit are floating, a laser pointer is built into the weapon body, and a through hole is located in the cartridge holder located in its middle part between the sockets of the cartridge holder.

 In the bottom part of the body of the weapon of self-defense (in the handle), an LED can be located showing the degree of discharge of the electrochemical current source.

 A light guide may be located in the through hole of the cartridge holder.

 A comparative analysis of the proposed solution with the prototype and other technical solutions in this technical field shows that the claimed solution is different in that the contact nodes of the unit are floating, a laser pointer is built into the weapon body, and a through hole is located in the cartridge holder located in its middle part between cartridge holder sockets. The implementation of the floating contact nodes made it possible to ensure the perfect alignment of the electric bangers of the contact node and the cartridge capsule, to reduce recoil and, as a result, the impact on the body of self-defense weapons, which in turn made it possible to place a laser pointer in it for easy aiming. 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 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 weapon of self-defense, 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 or electronic device) that provides a given shot sequence and indexing of the fired barrel.

An embodiment of the invention
This embodiment is only a special case of the device.

 The weapon consists of a cartridge holder with sockets (cassettes) 2, pivotally connected to the housing 1. In the sockets of the cartridge holder 2 are mounted cartridges with an electric igniter (not shown), the cartridges of which serve as barrels of this self-defense weapon.

 The cartridge holder 4 is located along the axis of the cartridge between its sockets. In the closed position, the cartridge is fixed on the housing by the latch 3. The rod-contactor is installed between the start key 5 and the microswitch (ESC) 7.

 The LC 9 switch is located on the left side of the case. The laser beam passes through the hole in the cartridge located in its middle part between the sockets of the cartridge holder. In the dark, the LC 8 is a convenient means of conducting targeted shooting. The discharge rate of the power source depends to the greatest extent on the frequency and duration of turning on the LC, you can monitor its discharge level by the indicator of discharge of the power source 11.

 An electric current source, a power source 10, is installed in the bottom of the self-defense weapon case. An electrochemical power source 10, for example, a Blik-2 battery, is used as an electric current source. It is possible to use a pulsed magnetoelectric current source, in which case the laser pointer will turn on for a short time just before the shot. It is most effective to use a pulsed magnetoelectric and electrochemical power source at the same time. In this case, the battery will be responsible only for the operation of the laser target indicator, and the pulsed magnetoelectric power source - for the issuance of a working pulse for the operation of the electric igniter. Cartridge sleeves are held in the slots of the cartridge holder and are pressed to the contacts 6 by the cartridge retainer 4. The contact block is made in the form of a separate assembly. Each of the contacts is a contact node 12, made in the form of a spring-loaded T-sleeve in cross section, with a Central hole for contact 6, which is fixed in the housing using a split washer. The contact node 12 is movably fixed in the housing 1, which makes it as if floating. The execution of the contact nodes floating ensures the ideal alignment of the electric drills of the contact node and the capsule of cartridges, as well as reduces the impact of recoil on the housing. Fire control in self-defense weapons (switching channels and the supply of working pulses) is carried out by an electronic system.

 The weapon works as follows. Insert one or more cartridges consisting of a cartridge case with an electric igniter, a propellant charge and a throwable body (pyrotechnic signal element, rubber bullet, light and sound element) into the cartridge holder with nests 2 weapons, and press the start key 4. Before shooting, if necessary, turn on the laser target 8, for this purpose the LC 9 switch is located on the left side of the case. The laser beam passes through the hole in the cartridge located in its middle part between the sockets of the cartridge holder. In the dark, the LC 8 is a convenient means of conducting targeted shooting. The discharge level of the power source can be determined by indicator 11.

 Cartridge sleeves are held in the slots of the cartridge holder and are pressed against the floating contacts 6 by the cartridge retainer 4.

 The production of the shot is as follows. When you press the start key 4, the movement from the key through the rod-contactor is transmitted to the microswitch (ESC) 7. The electrical circuits of all four channels are interrogated by a safe current, and then a working pulse is generated to trigger the electric igniter of the first cartridge with standard electrical resistance. The channel polling procedure takes no more than 10 μs. A shot is taking place. If there is no cartridge in any socket or the cartridge is defective (open, short circuit), then the working impulse is supplied to the next working cartridge. Such a scheme provides a guaranteed shot if at least one serviceable cartridge is installed in the gun.

 To produce the next shot, the start key 5 is returned to its original position and pressed again. Microswitch 7 repeats the channel survey and sends a working pulse to the cartridge with normal electrical resistance. 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 execution of the barrel in the form of a cartridge case with an electric igniter, the use of an electric current source and floating contacts for actuation made it possible to create an effective self-defense weapon, with low recoil, an improved aiming system and the exclusion of the possibility of its criminal use (the possibility of increasing the damaging factor).
