Abstract

FIELD: trench tools.

SUBSTANCE: invention relates to a wearable trench tool. A small tactical engineering shovel consists of a metal pentagonal blade 18 cm wide and 16 cm high, connected to a double-wing long-lever handle-pencil case 34 cm long with the possibility of fixing the blade in the working and carrying positions, respectively, when the blade forms one straight line with the handle-pencil case and when the canvas is pressed against the surface of the handle-pencil case. The handle-case is made in the form of a hollow cylindrical product, the lower part of which is equipped with a screw cap, with the possibility of storing a mine probe, a small-sized mine grapnel and TNT demolition slabs; it has the possibility of dividing into two halves along the long axis of the cylinder when the screw cap is loosened and removed. At the same time, inside the handle-case, the outer surface of which is made ribbed, there is a mechanism for pliers-nippers, the handles of which are halves of the handle-case, and the mine probe is made of metal with the possibility of extension from the handle-case with the possibility of fixing in the extended position. A hole in the shape of a number eight is made in the centre of the blade, which ensures the passage of the barrel of the assault rifle, and the edges of the front and side faces of the blade are sharpened, and four triangular holes are made in the side corners of the blade, allowing the functions of a nail puller to be realized.

EFFECT: small tactical engineering shovel provides an increase in the protection of the user of the shovel from hitting the head and chest with bullets and shrapnel during combat operations.

Description

The invention relates to a wearable trench tool.

On the defensive, due to the risk of being hit by an enemy (especially by snipers), the possibility of aimed shooting is difficult. To minimize this risk, a small special combined-arms blade has been developed, which is a modernization of an ordinary folding special blade with design changes that increase the engineering tactical and technical properties of the blade.

The closest analogue is a multifunctional sapper shovel (utility model patent RU 144375), which consists of a blade and a handle, characterized in that the blade is in the form of a flat rectangle made of metal with a sharpening at the end, a saw blade for wood, an ax edge, a bolster in the form of a flat rectangle of metal, put on the blade from the side of the handle in the form of a smooth straight circular cylinder of hard material, a sapper probe in the form of a needle with a pointed end on the working side, a sleeve for attaching a removable cap and knees of a sapper probe in the form of a cylinder, a removable cap spherical shape are made in the form of a single structure. The disadvantage of this technical solution is that it does not help to increase the security of personnel from hitting the head and chest with bullets and shrapnel in all types of combat.

The technical task of the claimed invention is to improve the engineering performance characteristics of a small special combined arms blade.

The solution of the technical problem is ensured due to the fact that a small tactical engineering shovel consists of a metal pentagonal blade 18 cm wide and 16 cm high, connected to a double-leaf long-lever handle-pencil case 34 cm long with the possibility of fixing the blade in the working and stowed positions, respectively, when the blade forms one straight line with the handle-pencil case and when the canvas is pressed against the surface of the handle-pencil case, while the handle-pencil case is made in the form of a hollow cylindrical product, the lower part of which is equipped with a screw cap, with the possibility of storing a mine probe, a small-sized mine cat and TNT checkers and with the possibility of splitting into two halves along the long axis of the cylinder when loosening and removing the screw cap, inside the handle of the case, the outer surface of which is ribbed, there is a mechanism for bringing to work the pliers-cutters, the handles of which are halves of the handle-case, and the mine probe is made of metal with the possibility extension from the handle-pencil case with the possibility of fixing in the extended position, while in the center of the blade there is a hole in the shape of the number eight, which ensures the passage of the barrel of the machine gun, the edges of the front and side faces of the blade are sharpened, and four triangular holes are made in the side corners of the blade, allowing to realize nail puller functions.

The achieved technical result consists in increasing the security of the user of the blade from hitting the head and chest with bullets and shrapnel in all types of combat.

The main objectives of the creation and application of the proposed technical solution is to effectively assist personnel in the performance of elementary engineering combined arms tasks (overcoming and arranging engineering barriers, fortification, field equipment of military formations, etc.) while increasing the degree of protection of personnel from frontal high-explosive, fragmentation and bullet lesions (head, chest) in all types of combat.

A small special combined-arms shovel (figure 1) has a height of 50 cm and consists of a multi-purpose pentagonal canvas 18 cm wide and 16 cm high and a double-leaf long-lever handle-pencil case.

Multi-purpose pentagonal canvas is made with the possibility of fixation in the working (figure 1) and transport (figures 2 and 3) positions.

In the side corners of the multi-purpose pentagonal web (figure 1) there are four triangular holes that allow you to implement the functions of a nail puller.

In the center of the multi-purpose pentagonal canvas (figure 1) there is a hole in the shape of the number eight, which provides the passage of the barrel of the machine.

The edges of the front and side faces of the multi-purpose pentagonal blade are sharpened to implement the functions of cutting and sawing small wood formations (thin trunks, branches, etc.), trimming, sanding logs, bayonet and pick-hoe development of soils.

A double-lever long-lever handle-pencil case is a hollow plastic (metal) product, inside of which there is a mechanism for bringing the pliers-nippers to work, is a container for storing a mine probe, small-sized mine cat, explosives (75-gram checkers, etc.). A mine cat is a combination of a small-sized metal, claw-folding tip with a nylon thread (thrown with a probe), which allows you to destroy enemy mines with wire target sensors or shift them to a distance of up to 30 m.

A mine probe (figure 2) is a metal (combined) product that allows you to detect solid objects (mines, etc.) in the ground at a depth of up to 20 cm.

Pliers-nippers (figure 3) is a metal product that allows you to capture and hold objects, cutting high-alloy wire with a diameter of up to 3.0 mm, as well as the simplest shock-mechanical development of rocky and frozen soils.

The handle-pencil case is made in the form of a hollow cylindrical product, the lower part of which is equipped with a screw cap, with the possibility of storing a mine probe, a small-sized mine cat and TNT checkers.

The handle-pencil case is made with the possibility of splitting into two halves along the long axis of the cylinder when the screw cap is loosened and removed. When dividing the handle-pencil case into two halves, these halves are the handles of the pliers-cutters - inside the handle-pencil case there is a mechanism for bringing the pliers-cutters to work.

The mine probe is made of metal, with the possibility of extension from the handle-case with fixation in the extended position - for example, using a cylindrical ring located in the upper part of the handle-case.

For ease of use of the spatula, the outer surface of the handle is ribbed.

A small special combined-arms shovel is located: in the stowed position - on the belt (rear);

in the working position - vertically, with a multi-purpose pentagonal canvas on the chest of the shooter or on the barrel of small arms.
