Description

The utility model relates to the field of defensive structures and is designed to protect personnel from the impact of hand grenades, grenades from various types of grenade launchers dropped from UAVs.

Currently, various designs of protective barriers are known.

Known anti-grenade and anti-bullet protective device (patent RU No. 2122702 dated 11/27/1998), containing deviating elements in the form of metal shock-absorbing grids installed in front of the protected object, while metal shock-absorbing grids, for example armored or chain-link grids, each of which is made with a different cell size, are located with a decrease in the size of the cells as the grids approach the protected object and are made in the form of curtains installed in a free, untensioned state at an angle to each other at a distance between them greater than the length of a grenade, and their distance from the wall of the protected object is 1-15 grenade lengths, and the curtain most distant from the protected object is made with a cell size of not more than the caliber of a grenade, and the curtain closest to the protected object - with a mesh size of not more than the caliber of a bullet.

The disadvantages of this device are the complexity of the design, which makes it difficult to use in the field and the presence of unmasking properties.

It is also known layered flexible armor, described in the utility model certificate to the patent of the Russian Federation No. 0002864 dated September 16, 1996, consisting of successively arranged layers of fabric based on high-modulus fiber, in which the thickness of the outer layers of the fabric and the number of weaves per unit length of the warp and weft threads is less than that of the underlying layers, and all layers are connected by stitching threads.

The disadvantages of this armor is that it is impossible to conduct surveillance through the armor and, accordingly, inflicting a retaliatory defeat on the enemy is difficult.

Also known anti-grenade barrier (patent RU No. 123132 dated 20.12.12) having at least one screen made of a metal mesh with a cell size of 25×25 mm, while the mesh is coated with hydrophobic properties. Fluorepoxy varnish is applied as a coating with hydrophobic properties. The coating thickness is 2-15 microns. The mesh screen is 2.5×1.5 m in size and can be mounted on the walls of the building by means of mounting modules providing a gap between the mesh and the building of 1 m. The mesh screen is fixed on a metal frame.

The disadvantage of this device is the use of metal frames made of metal mesh, manufactured for a specific object and, accordingly, the difficulty of adapting to another object, in addition, metal frames reduce the mobility of this device.

The closest in technical essence to the claimed invention is a protective camouflage screen (patent RU No. 2476810 dated February 27, 2013), consisting of a flexible coating placed on a transformable collapsible frame, having a layered structure, the upper layer of which is freely, without fixing, laid on the lower layer, made of a camouflage material, and the lower one is made of strips of wire woven metal mesh fastened together by means of flexible loops, edged around the entire perimeter with a flexible and durable material, while the metal mesh is made with a clear cell size of not more than 30 mm from a wire with a thickness of at least 2.5 mm and a mass of at least 0.0030 kgf ² /m ² .

The disadvantage of this device is the complexity of the design that determines the duration of the deployment time, the use of a metal mesh that does not fully ensure the concealment of the object in the IR and RL ranges.

The objective of the utility model is to create an anti-grenade protective device that neutralizes or minimizes the threat of damage to personnel from the fragmentation action of grenades.

The technical result of the claimed utility model is to eliminate the disadvantages inherent in existing anti-grenade protection devices, in particular, to increase the mobility of the anti-grenade protective device through the use of a collapsible frame and the use of lightweight and no less reliable synthetic materials.

The required technical result is achieved by the fact that the anti-grenade protective device consists of a flexible coating placed on a transformable collapsible frame, having the structure of a woven mesh with a cell that prevents the penetration of various types of grenades, both hand-held and fired from various grenade launchers, the frame elements and connecting elements are made of high-strength carbon fiber tubes inserted through loops along the edges of the woven mesh of aramid material, which creates an elastic web by moving and by fixing the connecting elements on the vertical elements of the frame, the frames are connected to each other in the upper part at sharp angles that contribute to the rolling or throwing of ammunition from the grid, in the lower part the frame is fixed in the ground, the mesh canvas is painted with an actual camouflage pattern.

The essence of the invention is illustrated by the drawing, where in Fig. 1 and FIG. 2 shows collapsible frames covered with woven mesh.

On FIG. 3 shows the layout of the anti-grenade protective device,

Where:

1 - upper connecting elements;

2 - frame elements;

3 - woven mesh;

4 - lower adjustable connecting elements;

5 - fixings in the ground.

The invention works as follows: the anti-grenade protective device is first brought into working position, for which the elements of the device are removed from the storage and transportation system. The upper horizontal elements of the frame (2) are threaded through the loops of the woven mesh (3), inserted and rigidly fixed in the upper connecting elements (1). Threaded through the loops of the side planes of the woven mesh (3), the vertical frame elements (2) are also inserted and rigidly fastened in the upper connecting elements (1). In the lower part, lower adjustable connecting elements (4) are put on them, into which, after passing through the loops of a woven mesh (3), the lower horizontal elements of the frame (4) are inserted and rigidly fixed. With the help of adjustable connecting elements (4) the woven mesh (3) is tensioned. The end surfaces are assembled in the same way. After that, the structure is placed over a shelter, such as a trench, and fixed in the ground with the help of fastening to the ground (5). It is necessary to adapt the woven mesh fabric (3) to the conditions of the terrain, additionally coloring it with a current camouflage pattern. The anti-grenade protective device is ready for operation.

Upon detection of those covered by anti-grenade protective devices, and attacking the occupied positions with hand grenades, VOG grenades, as well as grenades dropped from UAVs, when the woven mesh (3) hits the canvas, the ammunition is thrown to the side due to its own elasticity. A woven mesh (3) with a cell smaller than the grenades used prevents the grenades from entering the shelter and, after the grenade body breaks, prevents the personnel in the shelter from being hit by shrapnel. This is achieved through the use of para-aramid fibers, from which the braided mesh cord (3) is made, forming an ultra-strong material five times the strength of steel.

The use of this anti-grenade protective device, first of all, has a psychological impact on the enemy when deciding on the use of destruction devices. Having discovered the use of an anti-grenade protective device by personnel to protect against the damaging effects of grenades, the enemy realizes that he cannot guarantee an effective defeat. This forces him to use any other more powerful means of destruction, if available, or to test the effectiveness of the device with unpredictable consequences for himself.

Anti-grenade protective devices can be combined with each other to protect extended objects and used as a means of camouflage through the use of an up-to-date camouflage pattern and the absence of metal elements for detection by enemy radars. The mesh structure of the protective fabric and the ability to detach the end elements of the anti-grenade protective device allows the use of small arms without leaving the shelter.
