Description

The utility model relates to hand-held portable firearms and is intended for civilians for self-defense through the use of traumatic elements of non-lethal action for firing.

The proposed utility model is a comprehensive technical solution for the design of hand weapons and cartridgeless cartridge for it, connected by a common inventive concept of joint functioning and application.

The prior art is characterized by a pistol described in US Pat. No. 6,234,058 B1, F41A 9/17, 2001, comprising a vertically interlocked barrel and a removable magazine magazine loaded with a mechanism to the overload window, adjacent to which a swing shutter with a lodgement located in the handle adjoins, equipped with an expansion chamber for the accumulation of powder gases during firing.

The trigger kinematically, through the lever-cam mechanism, is connected with the striker of the hammer.

To increase shooting mobility, the magazine, equipped with a set of cartridges, is interchangeable, which, when installed on the barrel, is mechanically fixed by a housing latch.

The disadvantage of this compact pistol is the design complexity with precision precision actuators, which increases consumer value and limits serial production.

The short life of the gun is determined by low functional reliability due to mechanical wear by friction during dynamic loading of mating parts, resulting in backlash and gaps, which cause a noticeable decrease in firing accuracy, when jamming and failures.

The noted shortcomings were eliminated in self-defense weapons according to the patent RU 2172460 C1, F41C 3/00, F41A 19/58, 2001, which was selected as the closest analogue to the proposed one according to the technical nature and the number of matching features.

The well-known self-defense weapon (pistol) includes a handle pivotally connected to each other and a folding cartridge holder for four cartridges, the cartridge cases of which serve as trunks.

Cartridge propellant igniters are adjacent to spring-mounted electrical contacts mounted in floating supports connected to a switching power supply via an electronic firing control unit located in the handle.

The push button is mechanically rigidly connected to an electric current source supplying the electronic firing control unit and a laser target indicator emitting through the central waveguide in the cassette holder.

The advantage of the well-known weapon is the impossibility of direct criminal use, since the electric ignition cartridges are not on sale, and the live ammunition of small arms is equipped with shock-ignition capsules.

The weapon design is equipped with a switchgear, switching of which provides a given sequence of shots and indexing of the fired barrel, which expands the technological capabilities of firing.

However, the disadvantage of the known weapons is a large error of shooting due to the varied spread of the trajectory of the bullet from a priori differently offset from the aiming axis of the trunks.

In addition, combat readiness and mobility of shooting are limited by the inevitable manual extraction of spent cartridges and the relatively small capacity of the store.

The design of the traumatic cartridges is a sleeve, in the flange of which there is an igniter that acts upon initiating a propellant powder charge adjacent to the striking element, mainly of an elastic material (reinforced) having an aerodynamic shape, which are placed flush inside the sleeve or having a free acceleration section for the missile item described in patents RU No. 2179700, 2348892, 2453797, 2271512.

A common drawback of these cartridges for use in self-defense weapons is the presence of a cartridge case that must be manually removed after reloading for reloading, both with a single shot and with serial shooting from a cartridge, which limits the rate of fire and mobility of combat readiness.

More perfect is the design of a sleeveless artillery cartridge for a grenade launcher, described in patent RU No. 2282130, F42D 5/02, 2006, containing a warhead with leading protrusions for spiral rifles of the weapon barrel, additionally performing the functions of a means of obturation of gaseous products of combustion of a propellant charge, and it tied shank, made under the diameter of the barrel prechamber.

A combustion chamber filled with a propellant powder charge interacting with a central igniter capsule mounted in the bottom diaphragm equipped with outlet openings for powder gases distributed around the perimeter is made in the shank.

When fired, the shank, which acts as a powder cartridge case, flies with the grenade, thereby eliminating the limiting case extraction process.

By technical nature, the described grenade is the closest analogue to the proposed sleeveless cartridge for self-defense weapons.

The disadvantage of the described design is the unsuitability for using shellless ammunition in self-defense weapons, the purpose of which is the non-lethal action of the striking element.

The technical problem to which this real utility model is directed is to eliminate the noted drawbacks in order to increase the efficiency and accuracy of firing a simple-design pistol with cartridgeless cartridges from a high-capacity magazine, while reducing the consumer cost of self-defense weapons and cartridges for them.

At the same time, a concomitant problem that is comprehensively solved within the framework of the proposed self-defense weapon is the creation of a cartridgeless cartridge suitable for automatic firing from an advanced pistol.

The required technical result is achieved by the fact that in the well-known self-defense weapon, which includes a magazine with cartridges equipped with an igniter of a propellant powder charge, loading and initiation mechanisms connected via an electronic fire control unit with a power source, and a push button, at the suggestion of the authors, a magazine with a series cartridge-free cartridges loaded with a spring recharger, equipped with a slide gate mounted on the rod of the loading mechanism, made preferably in the form the core of the electromagnet, and positioned adjacent to the initiation mechanism, a coaxial trunk parallel to that locked to the magazine.

Distinctive features of the proposed technical solution provided an increase in the accuracy of fire and functional reliability of the pistol with sleeveless cartridges of non-lethal action, when it is used for its intended purpose and the capacity of the ammunition store is increased.

The execution of the loading mechanism in the form of a slide gate mounted on the core of the electromagnet is the simplest two-position quick-acting device for the unit-based supply of cartridges from the magazine to the line of fire, reliable in long-term operation.

The slide gate provides a piece grip of the cartridge, which in its lateral movement is cut off from a number of cartridges in the magazine.

Mounting the shutter on the core of the electromagnet, which operates in a two-position cycle, makes it possible to compactly store the magazine above the barrel.

The electromagnetic drive of the mechanical piece feed of cartridges to the line of fire is simply and reliably adapted in the structural diagram of the gun.

Another feature of the proposed complex technical solution is that a sleeveless cartridge for self-defense weapons, comprising a housing equipped with an obturation means, a propellant propellant combustion chamber adjacent to the igniter, and outlet openings distributed along the end face, is characterized in that the obturation means is made in the form calibrated shell of the housing made of antifriction material, in which there are reversible channels of the outlet openings communicating with the combustion chamber ring membrane.

The implementation of a cartridgeless case increased the rate of fire of the weapon, eliminating the manual extraction of spent cartridges, while increasing the capacity of the store.

The execution of the shell of the cartridge housing of anti-friction molding material reduced the tribodynamic loads of the internal ballistics to achieve the required cartridge parameters and is the simplest technological design of the obturation tool when firing cartridge-free cartridges of non-lethal action.

Reversible channels of the housing that connects the combustion chamber to the outlet openings are designed to form reactive thrust for a cartridgeless cartridge that provides a given cartridge flight speed and its kinetics.

The annular membrane at the outlet openings creates a conditionally sealed volume of the combustion chamber in service circulation, which serves to increase the pressure in the combustion chamber and then burns with hot gaseous products of combustion of the propellant charge, thrown through the coaxial outlet openings of the housing, which ensures the compactness of the functional cartridgeless cartridges.

The proposed modernization of the cartridgeless cartridge is aimed at minimizing the volume and mass of structural elements to increase the ammunition load of the store and compatibility with the simplest design of the gun with increased firing efficiency.

Therefore, each essential feature is necessary, and their combination in a stable relationship is sufficient to achieve the novelty of a quality that is not inherent in the signs of disunity, that is, the technical problem posed in the utility model is not solved by the sum of the effects, but by a new super-effect of the sum of the attributes.

The essence of the proposed group of utility models is illustrated by the drawing, which has a purely illustrative purpose and does not limit the amount of claims of the aggregate of essential features of the independent claims.

The drawing schematically shows: in FIG. 1 - a gun for self-defense; in FIG. 2 - cartridgeless cartridge; in FIG. 3 is a view A in FIG. 2 (without membrane).

The proposed non-lethal weapon (self-defense pistol) includes (Fig. 1) a parallel rigidly interlocked barrel 1 and above it a magazine 2 under sleeveless cartridges 3.

Magazine 2 in the gun is installed between the spring-loaded rammer 4 and the bolt 5 through a longitudinal window and is fixed with a latch (not shown conditionally).

A longitudinal row of six cartridges 3 is loaded with a spring-loaded rammer 4, therefore, its extreme cartridge 3 is placed inside a coaxially mounted slide gate 5.

Used in the proposed pistol cartridges 3 are made sleeveless (Fig. 2).

In the housing 6 of the cartridge 3, a combustion chamber 7 is made, filled with a propellant powder charge 8, to which a central igniter 9 (electrical or mechanical action) is adjacent.

The combustion chamber 7 by means of reversed channels 10 distributed around the perimeter communicates with the outlet openings 11 (Fig. 3), closed by an annular membrane 12.

The housing 6 of the cartridge 3 is externally coated with a polymer shell 13 (Fig. 2), obtained by casting directly onto the housing 6 in a detachable form from a material with a low coefficient of friction (polyamide, polycarbonate, etc.).

The shutter 5, which performs the functions of a sliding loading mechanism, is mounted on the core 15 of the electromagnet 16 mounted in the handle 14, carrying out the piece supply of cartridges 3 to the line of fire.

An independent power source 17 (pulse battery) is installed in the handle 14, which is connected through the electronic fire control board 18 to the initiating mechanism 19, coaxial to the barrel 1, and with a laser target indicator 20 located on the front end of the magazine 2, additionally serving as a support for the spring-loaded rammer 4.

A pressure bar 21 cooperates with the control board 18.

The gun operates as follows.

From the finger moving the hand holding the gun, the pressure bar 21 mechanically acts on the board 18, connecting it to a power source 17, which supplies energy to the laser 20, which forms a sharply directed light beam of radiation in the visible range of the spectrum, and to the electromagnet 16.

An electromotive force is induced in the winding of the electromagnet 16 when electric power is applied, as a result of which the core 15 retracts and moves the shutter 5, positioning it on the line of fire, in contact with the initiating mechanism 19, in particular the electric one, which supplies a pulse to the electric igniter 9 of cartridge 3.

When the electric igniter 9 is activated, a force of fire is formed, which ignites the powder charge 8 in the combustion chamber 7.

The gaseous combustion products of the powder charge 8, with a sharp increase in pressure, dynamically move along the reversing channels 10 to the outlet openings 11, where the membrane 12 is burned and jet-blown into the conditionally sealed volume of the shutter 5, forming a traction force for accelerated movement along the barrel 1 at a speed that ensures the flight of cartridge 3 to a distance of 10 m

The spring-loaded core 5, when the electromagnet 16 is de-energized, returns to its original position, where the next cartridge 3 of the magazine 2 with a rammer 4 is fed into the slide gate 5.

The kinetic energy of the shot of cartridge 3 is enough to stop the action and create pain shock without causing injuries incompatible with life.

By pressing the key 21 again, the cycle of operation of the actuating elements is repeated.

A comparative analysis of the proposed technical solution with identified analogues of the prior art, from which a comprehensive utility model does not explicitly follow for small arms specialists, showed that it is unknown, and taking into account the possibility of industrial serial production of self-defense weapons for firing cartridgeless cartridges in existing production, it can be concluded that the conditions of patentability are met.

Tests of the prototype pistol when shooting with cartridgeless cartridges of the proposed design showed the functional reliability of the weapon and cartridges, achieving the required flight speed and accuracy of the battle, good rate of fire and mobile reloading, which allows recommending self-defense weapons for serial production for delivery to customers.
