Description

 The invention is intended to be used as a means of personal self-defense against attack, while the effect of the weapon on the offender is based on the creation of toxic substances such as tear reagents around attacking a gas cloud. The weapon can be used as a civilian product, as well as a one-time personal defense self-defense weapon when loaded with an appropriate cartridge.

 The invention is the result of work on the creation of a small-sized firing device of a single use, portable design, disguised as a handle. A device of this type has a simple design, reliable in operation, convenient to use, safe to use, has small dimensions.

 A number of different designs of self-defense means are known, combined with various objects: knives, handles, umbrellas, canes, etc.

 So, the gas gun according to the application of Germany N 3310155 is a structure built into the glove. A gas pistol is characterized in that for the production of two shots two descents are provided and the upper and lower sides of the body are connected by means of grooves, the strikers are sent to the grooves. The drummer of the first descent fuse is a hook spring.

 Personal firearms combined with a pocket knife are also known.

 A known device for self-defense is a closed container for liquid, in which there is a chamber for a device that activates the liquid. A nozzle is installed on the front of the fluid container. The container is filled with non-toxic liquid. A plug is installed on the front of the nozzle to prevent fluid from escaping from the container until a certain point. The activating device for heating the liquid, compressing it and removing the plug is a cartridge placed in the chamber. When the cartridge is triggered, a high-speed jet of liquid is ejected from the self-defense device, directed by the defenders towards the attacker. The cartridge is filled with black powder.

 Known small arms in the form of a fountain pen contains a Central cylindrical element with a channel that occupies at least part of the length of the element. The first end element has a threaded part, which can be connected to the first end of the Central element. The first end element has a chamber to accommodate one cartridge and the barrel part located in the center of this element. The second end element is located at the second end of the Central element and is movably connected to it. The second end element has a central through channel, inside of which a central shaft is fixed. At the first end of the central shaft is the drummer. The central shaft enters the channel of the central element. The tool contains a device for translating the Central shaft and the second end element in a stress state relative to the Central element. A writing element is placed inside the central shaft. The second end element has an intermediate part and a tip connected to the thread with the intermediate part. The intermediate part and the tip can be rotated relative to each other to translate the writing element in the first or second open position.

 Other devices of a similar purpose are also known (personal protection weapons, batons for police, hand guns with tear gas, weapons for self-defense).

 All of the above devices are combined and have design complexity and are inconvenient to operate.

 Self-defense weapons are also known, having the form of a hollow cylinder with a central hole in the rear wall. At the front end of the cylinder, a guide rod with a longitudinal-axial hole and a keyway is firmly fixed. On the rod is a hammer, moving in the longitudinal direction under the action of an elastic coil spring. A centrally located axis is welded to the rear wall of the striker, the rear end of which passes through the hole in the transverse wall of the cylinder, and to the front wall of the strikers with a rigidly attached longitudinal key. The hammer comes into the longitudinal-axial hole of the guide rails, and the key in the keyway recess. At the front end of the cylinder, a drum rotatable around an axis is movably fixed with a trigger in which there is a central hole with a recess for the keys. In the normal position, the trigger mechanism prevents progressive movement of the striker along the inner lumen of the cylinder. A holder with a piston is placed inside the drum in front of the trigger mechanism, and a tear gas charge is in front of it. When the drum is rotated around the cylinder, the longitudinal hole and the keyway of the trigger mechanism are set exactly against the longitudinal hole and the keyway of the guide cylinder, the hammer is released and strikes the piston, igniting it. As a result, the tear substance is ejected forward with force. The design provides a device for transferring the drum from a safety position to a combat platoon.

 The analogue has the following disadvantages: complexity of construction, inconvenience of cocking, the possibility of disruption of the hammer during cocking and arming, the inconvenience of descent.

 A device [2] comprising a body, a barrel, a striker with a longitudinally axial blind hole for placing a combat spring and communicating with it perpendicularly located through a hole for installing a cock, which is installed with the ability longitudinal movement in the groove of the shutter body. In it, the fixation of the cock is carried out by a latch located in the longitudinal-axial hole of the striker and spring-loaded with a combat spring, i.e. by the platoon, the force of the mainspring is perceived through the clamp.

The disadvantages of the prototype in relation to the requirements are as follows:
the possibility of a spontaneous shot when cocking the drummer due to the lack of fuse;
the possibility of losing the latch during disassembly due to its small dimensions;
the possibility of incorrect placement of the latch during assembly, which leads to additional disassembly;
design complexity;
large range of parts.

 The aim of the invention is to provide a safe and easy-to-use portable firing device for protection against criminals.

 This goal is achieved by introducing the following design features that are different from the prototype.

 The cock is equipped with a recess in the size of the diameter of the mainspring, the depth of the recess is greater than the size of one coil of the mainspring. The housing is equipped with an outer annular groove with the possibility of placing a fuse in it. The fuse is made in the form of an open ring equipped with bevels along the line of the connector ring. The end face of the safety ring is in contact with the cock when the hammer striker is drowned relative to the shutter mirror. When the striker protrudes relative to the shutter mirror, the cock is partially located in the ring connector.

 These symptoms are significant.

 In the patent, information and technical literature, no analogues of such novelty were found.

 Figure 1 shows the position of the hammer during the descent in the operational position "fire", the striker protrudes relative to the shutter mirror; figure 2 the position of the cock during the descent of the hammer in the operating position "fire", the cock is partially located in the connector of the ring.

 Self-defense weapons consist of a body 1, a bolt 2, a barrel 3, a hammer 4, a cock 5, a combat spring 6, a safety ring 7, a retainer 8, a cap 9, a pin 10, a cover 11.

 The barrel 3 is equipped with a chamber "a" and a channel "b", the outer surface of the barrel is threaded for fixing in the housing (hard locking), a groove (undercut) "c" to accommodate the latch 8 and the groove "i". The housing 1 is a cylindrical part with a stepped through hole in the internal thread on both sides, a longitudinal groove "d" with a profile recess for the possibility of movement of the cock 5, an outer groove "e" to accommodate the ring fuse 7 and holes for the pins 10. Step through hole provides for the placement of component parts. The shutter 2 is made in the form of a cylindrical plate part with an opening for the striker striker and is fixedly mounted using a press fit and pins 10.

 The drummer 4 is provided with a longitudinally axial blind hole "f" formed from the front part of the striker "g" and a through hole for the cock, crossing the blind hole and perpendicular to the blind hole. The cock 5 in order to ensure the strength characteristics is made of an elongated cross section and provided with a recess "h" to accommodate the mainspring, the width of the recess is made in the size of the blind hole of the striker and in the diameter of the mainspring, and the depth should ensure that the coil is not out of the recess of the mainspring and be larger the size of one coil of the combat spring, which will ensure reliable fixation of the cock in the weapon. For the convenience of cocking, the end of the cock protruding from the housing is allowed to be designed as a head or other element of an acceptable shape. The cap 9 is provided for fixing the mainspring in the housing.

 The fuse 7 is made in the form of an open ring equipped with bevels "m" along the line of the connector rings for ease of removal of the cock from the "fire" to the "fuse" position. The ring is installed on the housing in the annular groove due to elastic deformation, while the bevels along the connector line of the ring should be facing towards the cocker.

 The latch 8 is provided for the convenience of fixing the weapon on clothes and is made in the form of a leaf angular spring equipped with a hole “k” for fixing on the barrel with a bend “l” for fixing on the body.

 The proposed weapon works as follows.

 To load a weapon, it is necessary to turn the barrel out of the housing by acting on the retainer 8, insert the charge and screw it all the way, while the safety ring must be rotated to the "fuse" position with the cock rest in the ring end.

 To produce a charge, it is necessary to cock the drummer before placing it on the cocking platoon after turning the cocked drummer, while the mainspring is compressed. The safety ring must be turned to the "fire" position. For the operation to be triggered, it is necessary to remove the cock from the platoon with your finger. An uncontrolled striker under the action of the mainspring punches the cartridge capsule, the charge is triggered from an ejection in the direction of the barrel. In the tilt position of the capsule, the cocker is partially located in the longitudinal connector of the ring, which corresponds to the “fire” position, while the protrusion of the hammer behind the shutter mirror is determined.

 The proposed weapon, put in the "fuse" position by turning the ring to the withdrawal of the ring connector relative to the groove in the housing to move the cock, eliminates the charge when the hammer is cocked and its breakdown (descent) due to the limitation of the cock on the end face of the safety ring.

 The proposed design is simple to manufacture, the housing is made in the form of a tube and the shutter in the form of a plate, the details are made by turning and milling using standard equipment. The range of parts has been reduced, the proposed weapon has 11 parts.

 When using the proposed weapons, the positive effect is expressed in improving operating conditions by eliminating the involuntary actuation of the charge during cocking, in simplifying the design, reducing the range of parts, ease of assembly and disassembly.
