Description

The proposed utility model relates to pyrotechnic devices and can be used to send distress signals or alerts to hunters, fishermen, tourists, etc.

Currently existing pyrotechnic signaling devices designed to be launched by hand, according to the method of triggering a signal (signal flare or sprocket) can be divided into the following types:

- reusable, using the bore with the chamber for trigger direction, increasing the height of the signal, having trigger-type trigger mechanisms in which special signal cartridges of the caliber are used. This type includes signal pistols (rocket launchers) and hunting smooth-bore weapons;

- reusable barrelless, in which the direction of movement of the signal is specified by the cartridge sleeve (for example, the Osa self-defense weapon) or by a sleeve mounted on the muzzle of the barrel, into which a super-caliber pyrotechnic element ("gas" revolvers and pistols) is installed. In the first case, the signal is initiated by electric start, in the second - by the flame of a shot of an empty (noise) cartridge;

- disposable, in which the case combines both a sleeve and a barrel and a starting device. To initiate a signal in such devices, a grater capsule, an igniter, is used. An example of such a device is a military disposable rocket launcher.

The closest technical solution of the claimed utility model is the "Signal rifle cartridge" (patent RU 2171444, the Bulletin "Inventions. Utility models" No. 21, part 1, 2001). The cartridge consists of a sleeve, an igniter capsule, an expelling charge of gunpowder, a wad and a star from a pyrotechnic composition.

All of the above types of pyrotechnic signaling devices have the following disadvantages:

- large sizes and weight;

- restrictions on circulation in accordance with the Law on Weapons.

The technical result obtained by the implementation of the claimed utility model is expressed in a decrease in dimensions, mass and in improving the safety of use, which allows to remove the restriction on the turnover of pyrotechnic means, i.e. classify this launching device as household goods freely sold to the public, the handling of which does not require special knowledge and skills, and use in compliance with the requirements of the attached instructions for use ensures the safety of people and the absence of damage to property and the environment outside hazardous areas.

The specified technical result is achieved in that the starting device is a cylindrical body with a cap, inside the body there is a percussion mechanism containing a spring, a striker with a central battle striker and a cocking button that is attached to the striker and moves freely in a longitudinal groove made on the body and having two additional approaches — a groove located at an angle to the longitudinal groove. In the front of the case, on the inner diameter, a thread is made and a seat is formed for attaching a threaded cartridge. The body and cap are made of high-strength polymer material, which does not allow the device to be used for firing live ammunition using a barrel - nozzle. There is a spring clip on the cap for easy mounting of the pyrotechnic signal device over the edge of a pocket or bag.

The starting device is designed to initiate a signal threaded cartridge, which contains a two-stage sleeve, inside of which are located an igniter capsule, a pyrotechnic element and gaskets. The pyrotechnic element can be installed in a sleeve on a cardboard ring. On the small diameter of the sleeve from the outside, a connecting thread is made for attaching the cartridge to the starting device. The sleeve of a two-stage form can be made of metal or high-strength polymer material.

The essence of the utility model is illustrated in Figure 1.

Figure 1 shows a drawing of a pyrotechnic signal device and a signal threaded cartridge.

The inventive starting device contains the following structural parts (see figure 1): housing 1, cap 2 and a signal threaded cartridge 3. On the housing 1 there is a longitudinal groove 4 with a first groove-approach 5 and a second groove-approach 6. Inside the housing 1 is located percussion mechanism comprising a striker 7 with a striker 8

and a spring 9, while a cocking button 10 is attached to the drummer 7. In the front part inside the housing 1, a partition 11 is made with an opening 12 for the output of the hammer 8. The cap 2 is equipped with a spring clip 13.

The signal threaded cartridge 3 consists of a sleeve 14 of a two-stage shape, inside of which are located an igniter capsule 15, a pyrotechnic element 16 and gaskets 17.

To start the signal, the cocking button 10 of the starting device is installed in the first groove - inlet 5 on the safety cock for safety, then screw the signal cartridge 3 on the seat in front of the housing 1, to the partition 11. The shock mechanism is cocked by moving the cocking button 10 from the safety first the groove — approach 5 into the combat second groove — approach 6, compressing the spring 9. Then, the cocking button 10 is removed from the second groove — approach 6 into the longitudinal groove 4 and under the action of the spring 9, the hammer 7 begins to move forward the firing pin 8, in contact with the cartridge 3, breaks the igniter capsule 15. When the igniter capsule 15 is activated, the powder charge of the pyrotechnic element 16 ignites. Under the influence of the pressure of the powder gases, the pyrotechnic element 16 starts to move, and after departure from the sleeve 14 lights up and rises to a predetermined height providing signal creation. The combustion of the pyrotechnic element 16 at a height eliminates the risk of ignition of flammable objects on the ground.

The reduction in size and weight of the launch device is achieved through the use of polymeric materials and the simplification of the design.

Design features such as the absence of a barrel, the presence of an internal thread for attaching a signal threaded cartridge, and the use of a central combat striker allow the launching device to be used only for its intended purpose - to supply signals in the form of a rocket (asterisk) takeoff to a height of about 40 meters.

Thus, the proposed starting device and a signal threaded cartridge can be used for distress and warning. The use of cartridges confirmed their high reliability and compliance with safety requirements when using them.
