Description

The invention relates to hand-held portable firearms and is intended for use in self-defense for the temporary disabling of manpower by firing a traumatic element.

A device related to self-defense is known according to the patent of the Russian Federation for invention No. 2203466, comprising a self-cocking trigger mechanism, a cartridge feed from the magazine and a cartridge latch when fired, mounted in the housing. The trigger mechanism consists of a base, a striker, a mainspring, a striker with a return spring, a trigger with a return spring and a fuse. Additionally, the trigger mechanism is equipped with a cocking plate. A cocking plate is mounted on the axis of the hammer in contact with it with the possibility of displacement relative to the hammer in a plane passing through the axis of the hammer. The hole for the axis of the hammer in the plate is oval. The axis of the hammer is embedded in the body of the device. The base is mounted with the possibility of rotation around the axis of the drummer. A slot is made at the base, in which a limiter is placed in the form of a pin rigidly fixed in the housing. The latch is made in the form of an incomplete hollow circular cylinder with two bases and a surface equidistant to the surface of the cartridge.

The latch is mounted for rotation relative to the longitudinal axis. The trigger is kinematically connected by rods with a cocking plate and a latch.

The disadvantage of this device is its kinematic complexity.

Closest to the claimed in its technical essence is a self-defense weapon according to the patent of the Russian Federation for invention No. 2172460, containing a holder of cartridges, barrels made in the form of cartridge cases, and a mechanism for actuating. The cartridge cases are made with an electrocapsule, and the actuation mechanism comprises a pulsed magnetoelectric or electrochemical current source electrically connected to a switchgear comprising a contact block.

This device has limited functionality associated with the limited one-time equipping of its ammunition in the form of four cartridges, after the use of which considerable time is required for reloading the device.

The objective of the proposed proposal is to expand the functionality of the device.

This is achieved by the fact that a self-defense weapon using cartridges with an electric capsule, containing a cartridge holder and an actuation mechanism having an electric igniter of cartridges and an electric current source, is characterized in that it is equipped with a magazine with cartridges located in the body shaft, in the upper part of which there is an electric current source and a tray for accommodating an actuation mechanism therein, consisting of a breech block having a channel for installing a cartridge supplied from the magazine and an ejector, and of an electric igniter of cartridges connected to the breech, made of a base having two protrusions interacting with the breech, on which the bottom of the cartridge rests, on the base of the electric igniter of the cartridges there is a contactor rod and a three-arm lever, one arm of which interacts with the contactor rod, and the other - with the contact of the electric current source, while the contactor rod interacts with the cartridge electrocapsule.

The attached illustrations illustrate the essence of the proposal.

7-10 given a sequence diagram of the proposed weapon of self-defense.

The self-defense weapon (Figs. 1 and 2) consists of a casing 1, in which a shaft 2 for a magazine 20 with cartridges 24 is made. In the upper part of the casing 1 there is a tray 3, which serves to house the actuation mechanism consisting of breech 4 and the associated electric igniter cartridges 5. The magazine 20 is held in the shaft 2 by means of a latch 6. The tray 3 has a continuous rear wall 7 (with a half-ring cutout 8 for the strut 40 of the electric igniter 5). Front tray 3 is closed by the front wall 9 (attached inextricably). In the front wall 9, a channel 10 is made for the trigger 11 and a recess under the pinion shaft 12. A gear rack 13 is made on the trigger. It interacts with the pinion shaft 12. A shot is fired through the window 14 of the front wall 9. Through the window 15 of the tray 3, the spent sleeve is removed. Easily removable strap 16 (conventionally shown removed) closes the channel 10 and the recess under the pinion shaft 12, keeping them from shifting. The spring-loaded pusher 17 (the spring is placed in the channel 18 of the housing 1) serves to return the trigger 11 to its original (upper) position after firing. The process 19 of the right wall of the shaft 2 (Fig. 2) serves to interact with the draft of the magazine 20. The removable cover 47 closes the tray 3 from above and carries an electric current source - battery 48. The elastic contact 49 (Fig. 10) is isolated from the housing 1.

Magazine 20 (FIGS. 3 and 4) consists of a thin-walled housing 21, in which a feeder 22 is placed, which is pressed by a spring 23. The cartridges 24 are held from being prematurely pushed by the feeder 22 upwards with a latch 25, which is designed as a spring-loaded (using a torsion spring 26) two-arm lever and mounted outside the housing 21 with the possibility of swinging around the axis 27. In the initial position of the store (outside the arms), the spring-loaded (using the spring 28) rod 29 extends with its upper end under the lower shoulder 30 of the latch 25 and prevents it from turning outside the store along d the action of the cartridge 24, pressed against the latch 25 by the feeder 22. Detachable bottom of the store (not indicated) of conventional design.

The breech 4 (figure 5) has a channel 31 for installing the cartridge, is equipped with an ejector 32, made in the form of a two-feather torsion spring mounted on the axis 33 of the breech. At the front end of the breech 4, a groove 34 is made for the transverse dowel of the gear shaft 12, so that the breech 4 and the gear shaft 12 rotate as a unit. The shoulder 35 at the front end of the channel 31 serves to stop the barrel of the cartridge 24, protecting the cartridge from falling forward (in the direction of fire). The wings 36 and 37 of the breech are used to hold the next cartridge in the store when the breech is in extreme positions (Fig.7-10).

The electric igniter 5 (Fig.6) consists of a base 38, on which the bottom of the cartridge 24 rests, and on the base 38 there are two protrusions 39 for connecting to the breech 4. The stand 40 is also integral with the base 38 and carries a three-arm lever 41 mounted it can rotate on the axis 42, and a spring-loaded (spring 43) contactor rod 44 is supported on the long arm of the lever 41. The lever 41 and the contactor 44 are isolated from the base 38 of the electric igniter and, therefore, from the weapon body 1. The lower arm of the lever 41 starting position It also relies on an isolated thrust axis 45, which receives the force of the spring 43. The upper inclined protrusion 46 of the lever 41 serves to interact with the elastic contact 49 when the breech 4 is rotated to the firing position.

The operation of the mechanism is as follows. First, in the usual way, the magazine 20 is equipped with cartridges 24 (by inserting them under the latch 25 and recessed into the magazine case). Then, the equipped magazine is inserted into the shaft 2 until it is secured with a latch 6. In this case, the appendage 19 of the right wall of the shaft 2 drowns the draft 29 of the magazine and brings its end out from under the lower shoulder 30 of the latch 25. The latch 25 (spring-loaded with a weak spring 26) ceases to impede the progress of the next cartridge 24 up. This advancement is limited to wing 36 of breech 4 (FIG. 7). When you press the trigger 11, the gear rack 13 begins to rotate the pinion shaft 12 and the breech 4 and the electric igniter 5 connected to it clockwise (if you look against the direction of fire). When the channel 31 of the breech 4 passes over the magazine 20 (Fig. 8), the cartridge 24 moves upward, pushing the latch 25 and twisting the ejection spring 32 of the breech 4. When the breech 4 approaches the leftmost position (Fig. 9), the upper inclined lever protrusion 46 41 of the electric igniter 5 presses on the elastic contact 49 (Fig.6 section AA, on which the arrow conditionally shows the direction of the pressure force of the elastic contact 49 on the protrusion 46). The lever 41 rotates and sends the spring-loaded contactor rod 44 forward, the end of the rod touches the central electrode of the cartridge 24 cartridge, the circuit closes and a shot is fired. When releasing the trigger 11, the spring-loaded pusher 17 returns it to the upper position, while the breech 4 and the electric igniter 5 are rotated counterclockwise (figure 10) to the extreme position. As soon as the breech channel 31 is opposite the window 15 of the housing 1, the spent sleeve 50 is thrown out by the ejecting spring 32. When you press the trigger 11 again, all actions are repeated until all cartridges in the magazine are used up. An empty magazine 20 can be quickly replaced by a spare one.

Tests of the prototype showed effective and reliable operation of the design of the proposed device.
