Description

The invention relates to hand-held devices for signaling purposes, automatic triggering of torches, lighting stars, etc., using generated gases, and can be used for self-defense when repelling stray or wild animals with a sound and sound force generated during the combustion of pyroelements installed in a replaceable cartridge.

The level of this technical field is characterized by the design of self-defense weapons described in patent RU 2172460 C1, F41С 3/00, F41А 19/58, 2001, which contains a folding firing cartridge (multi-seat cartridge) with equally distributed channels around the perimeter for functional cartridges, cartridges which serve as a short barrel for firing at a limited flight distance.

The cartridges are adjacent to the support, where the spring-loaded axial electrical contacts are located, connected through an automatic switch having a firing control device, to a magnetoelectric pulse current source, which is driven by a push button.

The disadvantage of the described pistol is the complexity and duration of reloading cartridges, which can be criminally retool.

The described shooting device for industrial production must be licensed as a weapon of limited destruction, and its acquisition is possible only with the registration of permits, which limits the practical use of public products, in particular for scaring stray dogs and wild animals.

The noted drawbacks are eliminated in a manual gas-generating device of impulse action according to patent RU 138470 U1, F41Н 9/10, 2013, which is selected according to the technical nature and the number of matching features as the closest analogue to the proposed device.

Known gas-generating device of pulsed action contains placed in a case having the shape of a bent palm of a person’s hand, a multi-seat cartridge with functional pyroelements, an automatic switch with a power source that interacts with a push button, which are electrically connected.

The pyroelements are inseparably pressed to current-carrying supports, inside of which there are electrical contact contacts with an automatic switch that controls the procedure for initiating pyroelement igniter caps.

The removable disposable cartridge is equipped with dimensional latches in the windows of the end-face copiers of the case, one of which has a push lever designed to remove the used cartridge and replace it with a new one.

Pyroelements during combustion generate gaseous products ejected in the form of forcefully bright glow, accompanied by a sharp sound of high tonality, which together has a shocking, stopping effect on animals.

The inseparable fastening of pyroelements in a removable cartridge excludes the possibility of altering the device into a firing element, that is, as a pyrotechnic, it does not require an acquisition license, which determines the possibility of free civilian use.

The execution of the body in the form of a handle, in the shape of a bent palm of a person’s hand, is necessary to exclude external similarity to shooting weapons.

However, a continuation of the advantages of the known device is its inherent drawback: narrowly-targeted use only as an “anti-dog” for scaring stray dogs and wild animals with pulse-generated light and sound forcephases of the gaseous combustion products of pyroelements.

The kinetic energy of the generated gaseous products is not used.

The technical problem to which the present invention is directed is to expand the technological capabilities of a pulsed gas generating device suitable for universal use both as a local repelling agent and for setting high-altitude signals.

The required technical result is achieved by the fact that in the known manual gas-generating device of pulsed action, the pyroelements of which are permanently installed in the autonomous cells of a multi-seat replaceable cartridge equipped with dimensional latches for fastening in the landing socket of the case, shaped like a bent palm of a human hand, while the pyroelements are adjacent to the contacts at the bottom of the landing jack, which are connected through an automatic switch with a power source equipped with a push button, is turned on I according to the invention on a ledge on the cartridge cells further pyroelectric element mounted with clearance coated obtyuriruyuschey lid functional zvezdki pyrotechnic composition, wherein the cartridge is provided with ribs on the outside and a through central window whose generators are made congruent adjoining surfaces.

Distinctive features of the proposed technical solution informed the device of a new quality in triggering signal and lighting pyrotechnic stars to a height by means of the accumulated energy of gaseous products generated during the combustion of pyroelements, which can also be used autonomously as generators of a local light and sound force against an aggressive attack by animals.

Essentially, the proposed invention is a barrelless firing handheld device of universal application using functionally and structurally different but compatible cartridges.

Placing functional stars on the ledge of the cartridge cells with a guaranteed gap forms the pyroelement combustion chamber, where the pressure of the accumulated gaseous products of combustion increases, the energy of which is throwing the burning pyrotechnic star to a predetermined height.

When burning functional stars, a gas-aerosol formation is formed that emits in the optical range, possibly colored with different colors of smoke signals, which is a new quality that is not inherent to known analogues.

The jumpers between the cells of the cartridge and its central through window form equidistant arches, which serve as a curved beam, which works mainly in compression, causing not only longitudinal but also transverse reactions in the supports (two other jumpers of the cartridge outside the window), thereby increasing the most bearing strength of the cartridge, stable under dynamic cyclic loading.

Asymmetric dynamic loads on the cartridge during the autonomous functioning of the equipment in its cells are perceived by adjacent contour forces, that is, unilateral deformations are damped in the bridges between the cells caused by the increased pressure of the accumulated gaseous substances formed during the combustion of pyroelements to throw stars, excluding the deformation of the cartridge.

Equipping the cartridge with external stiffeners, by definition, allowed, by increasing the bearing strength, to develop inside the cells the increased pressure of the gaseous products of combustion of pyroelements.

The profile of the through central window in the cartridge provided damping of non-uniform dynamic loads during the pulsed generation of gases accumulated in the cells necessary to achieve a given impulse of the throwing power of the functional star to the distance of autonomous flight, while maintaining the structural integrity and functionality of the cartridge for its intended use.

That is, the cartridge is profiled in such a way that it is suitable for the use of functional (light-sound, lighting, etc.) charges, throwing at a considerable distance.

The proposed device is used for a new purpose, when gas-generating pyroelements serve as a propellant for additional functional stars.

Moreover, the device according to the invention is suitable for use without alterations, as an “anti-dog” like a prototype when a cartridge with three pyroelements is installed without additional equipment in the cells. Thus, the proposed device is a universal starting tool for various pyrotechnic charges, local or high-altitude action, which expands the technological capabilities of its application.

The essence of the proposed manual gas-generating pulsed device is illustrated by drawings, which have a purely illustrative purpose and do not limit the scope of the claims of the totality of the essential features of the formula.

The drawings show:

in FIG. 1 - general view of the device (without cover);

in FIG. 2 is a view along arrow A in FIG. one;

in FIG. 3 is an embodiment of the anti-dog device.

In the plastic case 1 (Fig. 1 and 3), made in the shape of a bent palm of a person’s hand, which is equipped in the working end with a seat socket 2 for a replaceable multi-seat cartridge 3, there are two (Fig. 1) molded pyroelements 4 or three pyroelements 4 in the cartridge 5 (FIG. 3) generating gaseous combustion products upon initiation.

In the cartridge 3, between the two cylindrical cells 6, at the bottom of which pyroelements 4 are pressed in, a through window 7 is made, the profile of which is congruent to the adjacent surfaces of the cartridge 3: arc from the side of the cylindrical cells 6 and rectilinear parallel to the generators of the cartridge 3 (Fig. 2). Thus, between the central window 7 and the cells 6 are formed arched jumpers 8, tightened in buttress - supporting jumpers 9.

In the device of FIG. 3, free-flowing gaseous products of combustion of pyroelements 4 in the form of a short-focus force produce local light and sound action, and according to FIG. 1 - gaseous combustion products accumulate in a closed combustion chamber 10, where the pressure rises.

The combustion chamber 10 is formed under a functional pyrotechnic star 11 mounted on the ledge 12 of the cell 6, with a guaranteed clearance relative to the pyroelement 4.

The sprocket 11, made of a lighting or signal (smoke-generating color) pyrotechnic compositions, is covered with an obturating lid 13 fixed in cell 6.

Around the perimeter of the cartridge 3, reinforcing ribs 14 are made.

The pyroelements 4 are based on spring-loaded autonomous electrical contacts 15, which are connected to an automatic switch 16 having a program for connecting to a power source 17, actuated by the button 18 from the push button 19.

The contacts 15 are placed inside the flat springs 20 (Fig. 2), mounted on the bottom plate (not shown conditionally), electrically connected to the automatic switch 16.

On the overall ends of the cartridges 3 and 5, spring latches 21 are made, kinematically locked when installed in the windows 22 of the housing 1 located behind the wedge copiers 23, compressing the cantilever latches 21 when the cartridges 3, 5 are fed into the seat 2 until the pyroelements 4 stop in the electrical contacts 15 .

In this case, the flat springs 20 are loaded, which are deflected completely into the carrier plate, which ensures the power closure of the cartridges 3, 5 in the seat 2 and the gapless contact of the pyroelements 4 to the corresponding spring-loaded electrical contacts 15.

Above one of the windows 22 (top in the drawing) of the copier 23, a push lever 24 is mounted on the housing 1 for opening the structural elements of the device when removing cartridges 3, 5 with used pyroelements 4 from the slot 2.

The device operates as follows.

When you press with your finger the hand holding the device on the key 19, the power source 17 is connected to the switch 16, which automatically initiates one of the three contacts 15.

The current pulse from the electrical contact 15 is transmitted to the adjacent pyroelement 4, initiating its igniter sensitive to thermal energy, igniting the pyrotechnic equipment of the pyroelement 4.

During the combustion of the pyroelement 4, gaseous products are generated, which in the open cartridge 5 form a functional luminous force, which is accompanied by a sharp loud sound, and in the cartridge 3 they accumulate in the combustion chamber 10, where the pressure rises.

Hot combustion products accumulated in the combustion chamber 10 ignite the pyrotechnic star 11, which is thrown by a force pulse from the gas pressure in the combustion chamber 10 from the guide cell 6 to a height of 70 m, where a gas-aerosol formation is formed that emits in the optical range, which serves to illuminate or as a colored smoke signal, clearly visible and distinguishable from a distance.

After spending the pyroelements 4, the fingers press the lever 24, disengaging the end latch 21 from the mesh with the window 22, which slides along the wedge copy 23, pushing the cartridge 3 or 5 out of the landing socket 2 of the housing 1.

Having grabbed the edge of the cartridge 3, 5 protruding beyond the end of the housing 1, it is removed from slot 2, where a new equipped cartridge 3 or 5 is inserted, depending on the intended use.

A new cartridge 3, 5 is fed into the seat 2, compressing the leaf springs 20 and closing the spring-loaded electrical contacts 15, while the cantilevered latches 21, sliding along the copiers 23, deviate to the center of the cartridges 3, 5.

When the latches 21 reach the windows 22 in the copiers 21, they spring open and kinematically close the cartridge 3 or 5 in the housing 1 - the device is ready to continue to work as intended.

The device can function in a single start or in a queue with the successive operation of all pyroelements 4, after which the cartridge 3, 5 is replaced by a new one.

The proposed manual gas-generating device is universal in functioning as an “anti-dog” or for setting a high-altitude luminous cloud or colored smoke signal, depending on the configuration of the pyrotechnic stars 11.

The installation in the cells of the cartridge 3 of additional stars 11 of a functional pyrotechnic composition under the obturation lids 13 is aimed at accumulating in the combustion chamber 10 the gaseous products of combustion of the pyroelements 4 to obtain a propelling pulse capable of raising the burning star 11 to a predetermined height, where it forms a luminous gas-aerosol formation emitting into optical range, or colored smoke cloud.

Comparison of the proposed technical solution with the closest prior art analogues did not reveal an identical match of the totality of the essential features of the invention.

The proposed differences of a manual gas-generating device are not obvious to a specialist in self-defense weapon technology, which does not directly follow from the statement of a technical problem.

The manufacture of the proposed universal multifunctional device can be carried out in series at the existing pyrotechnic production, to equip customers.

From the foregoing, we can conclude that the invention meets the conditions of patentability.
