Description

FIELD OF THE INVENTION

The invention relates to shells of remote stun guns (DESHO) and can be used in non-lethal stun guns of remote action for law enforcement services and citizens.

State of the art

A well-known DESHO projectile according to RF patent No. 2275576, containing a solid hollow shell that is not deformable when fired, is inseparably connected to it and made of conductive material with a weighting head on which a fixing device is placed on the target (for example, a needle with a horn). Inside the shell there is a conductor pressed inside. When fired from DESHO, a hollow shell with a current lead flies out of DESHO. At the same time, the end of the current lead fixed to the DESHO pulls the current lead of the hollow shell. During the flight of the projectile, the current lead is pulled out of the shell until the projectile hits the target and secures it to the target. The design of the projectile consists of at least two labor-consuming parts, a shell and a head, which must be performed with high accuracy or using high-tech assembly micro-operations, since the head for integral part is either pressed (precise fittings) into the shell, either welded or soldered to it, or glued with high strength glue to prevent inertial displacement of the head when accelerating the projectile. Due to the necessary precision of manufacture and high-tech operations using expensive equipment and highly qualified specialists, the final price of the projectile is unreasonably high. The hard head and sheath are an additional traumatic factor for the target, in addition to the needle with the horn, due to its hardness and high momentum due to the large mass of the hard shell usually made from a steel tube. As a prototype, a DESO shell was selected according to the patent for a utility model of the Russian Federation No. 105020. The projectile has a weighting head with a needle, which has a rampart and a flexible (easily deformable when the projectile hits the target) shell that protects the conductive line, pressed like an analogue, from loss of deformation (loss of a dense form of laying the current lead). The shell, as a rule, is made of paper having an adhesive surface facing the laying of the current lead and further preventing it from disintegration. When fired from DESHO, a deformable shell with a conductive pressed inside it flies out of DESHO. At the same time, the end of the current lead fixed to the DESHO pulls the current lead out of the sheath. During the flight of the projectile, the current lead is drawn from the shell until the projectile hits the target and secures it to the target. In this design, the shell eliminated the hard shell, which increases the trauma on the target, reduced the mass of the shell and its traumatic impulse.

Disclosure of invention

The invention is aimed at solving the problem of creating a DESHO projectile having the minimum possible trauma when acting on a target, increasing the initial velocity of the projectile, increasing the length of the conductor in the projectile, reducing its cost in connection with a reduced number of parts.

The essence of the invention lies in the fact that the projectile of a remote stun gun contains a device for securing to the target, tightly laying the current lead in the form of an elongated shape, consisting of an axially pressed single-layer frameless coil of an electric wire or a multilayer frameless coil of a laid coil to a coil of wire, a holding element of the said shape from disbanding, the fixing device on the target is fixed directly to said laying of the current lead, or to said element holding the deformation, or on the said element and the said element at the same time, one end of the current path of the said stack is electrically connected to the said device for securing to the target or fixed next to it with a spark gap, and the other end comes out of the end face of the elongated stack opposite to the device of securing to the target.

An additional feature is that the deforming retention element mentioned can be deformable or non-deformable during the shot.

An additional feature is that the deformable said deformation retention element consists of a bonding or cementitious substance.

An additional feature is that in the aforementioned stacking of the current lead, formed from a multilayer frameless coil with the current lead laid in layers round to turn, the end of the current lead fixed to the sleeve of a unitary cartridge, cartridge or barrel leaves the first lower layer of the stack, and the end of the current lead, fixed on the front end of the shell or on the device for fixing on the target, comes out of the last top layer of laying.

An additional feature is that in the aforementioned stacking of the current lead, an axial channel is formed, along the entire length of which or in front of which there is a powder of lead or tungsten alloys or powders of the mentioned metals in a pure state.

An additional feature is that a track of electrically conductive paint or foil is laid on the outer surface of the current lead, or a thin wire is attached.

An additional feature is that the device for securing to the target consists of a needle with a horn, having support areas at the end opposite the tip, in the form of an end bent at an angle of 90 ° with respect to the axis of the needle, or a flattened end, or an annular bend.

An additional feature is that the device for securing to the target consists of a needle with a horn fixed to the supporting disk.

Brief Description of the Drawings:

Figure 1 shows a shell with a deformable shell in the context.

Figure 2 shows a projectile with a deformable deformation retention element in the form of glue or cementitious substance.

Figure 3 shows various types of endings of the device for fixing on the target (needle with a horn).

The implementation of the invention

Figure 1. The DESHO projectile, otherwise referred to as a probe or dart, contains a stacking 1 of the current lead, the dense (compact) shape of which keeps the deduction element from disintegrating in the form of deformable during assembly of the projectile, and when the shell is fired and hits the target 2, and the fixing device on Goal 3 (for example, a needle with a horse). The needle 3 is glued to the sheath and the end of laying 1 with glue 4. The sheath can be made, for example, of stretch film (stretchfilm), and the stretch film tightens and holds the conductor due to the electrostatic interaction of the layers of the stretch film and the wire insulated with fluoroplastic or its copolymers .

In other embodiments, the shell may be made of an elastic polymer coating applied to said stack during or after its manufacture by coating or spraying. In necessary special cases, for example, when an increased impulse is required when acting on a target (very thick leather clothes, rubber clothes, for example, a wetsuit), a deformable weighting material, for example, thin lead foil, can also serve as a sheath that keeps the conductor from laying out.

The stabilization of a projectile fired from a DESO throwing device while flying with the needle forward occurs due to the constant effort of pulling the current lead at the rear end of the projectile directed towards the weapon, but in versions with a form-holding element from disbanding in the form of a shell or polymer spraying, as well as due to aerodynamic stabilization, since as the current lead is pulled out of the shell during the flight of the projectile, the center of gravity of the projectile shifts more and more, and the light rear part of the released shell plays p The role of the aerodynamic stabilizer. The weight of the prototype projectile with a weighting metal head, a holding element for deforming the laying of the paper conductor (paper shell), a steel needle with a horn, and 4.5 m of the length of the conductor laying is 3.45-3.55 g.

The weight of the proposed shell with a paper shell, a steel needle with a horn, and 4.5 m of the length of the current lead laying is 1.8-1.85 g.

The weight of the proposed projectile with a current lead completely extended from the paper sheath (with a total open length of 4.5 m) and a steel needle is 0.25-0.3 g.

Due to the small weight of the projectile, small impulse compared to the prototype, there is also the possibility of increasing its muzzle initial velocity, and, accordingly, the speed of the target. The speed of the prototype projectile weighing 3.5 g is 40-50 m / s, with an impulse of 0.14-0.175 kg⋅m / s. The speed of the proposed projectile with its weight of 1.8 g, with the indicated impulse will be already 75-95 m / s, that is, twice as much as in the prototype projectile. The muzzle energy of the proposed projectile at its above weight and speed will be higher than that of the prototype projectile, however, due to the absence of a metal non-deformable head, trauma to the target will be negligible even with a higher muzzle energy. Increasing the speed of the projectile is of great importance when shooting at a moving target, it allows you to reduce the necessary lead when firing, and at small shooting distances and not give lead. Due to the absence of the head of the proposed projectile, having a length of about 1/6 of the total length of the body of the projectile, the number of conductors in the laying of the proposed projectile can be increased by 20%, which increases the range of the DESO. In the case of the use of the element retaining the form in the form of glue or cement, the number of conductors in the installation is further increased due to the exclusion of the sheath volume. The proposed projectile does not contain a weighting head having a weight of about 49% of the total weight of the prototype projectile and made of non-ferrous metals (lead, brass), respectively, the cost of its manufacture is significantly reduced.
