Abstract

FIELD: mechanics.

SUBSTANCE: device contains convex elements, one of the surfaces of which is spherical and leans upon the protected surface. Convex elements are made of elastic material and connected between each other by connection straps that form ribs at the outer side and grooves at the side facing the protected surface.

Description

The invention relates to protective equipment and can be used in the defense industry to create protective equipment for people and equipment from the action of mechanical weapons.

Known protective structure containing external and internal protective bags, between which there is a gasket made of foamed plastic material, which is made in the form of a tape with fixed folds placed with a constant step from the side of the protected object, and placed in series in two outer shells, and the inner protective bag consists of a rigid material adjacent to the gasket and a subsequent elastic material with a higher density than that of the gasket (RF patent No. 2034228, F41H 1/02).

The disadvantages of this design are also the complexity of the design and the limited time for stretching the shock pulse.

Also known is the armor containing individual plates mounted with their spherical supports on the armor plate, in which the plates are pivotally relative to each other with the possibility of relative movement and rotation, each plate being made in the form of a regular hexagon, and a layer of elastic material is placed between the plates and the armor plate ( RF patent No. 20111140, P41H 5/02).

The disadvantage of armor is also the limited time for stretching the shock pulse.

The closest in technical essence is a body armor containing a bib made of aluminum lining and ceramic lining, equipped with reflective elements, the outer surface of the ceramic lining made in staggered cells in the form of a concave hemisphere in which the reflective elements are fixed, the latter being made with on the one hand in the form of a convex hemisphere, and on the other - in the form of a cone, and fixing materials are placed between the cells and reflective elements. The radius of the concave hemisphere of the lining is greater than the radius of the convex hemisphere of the reflecting element (RF patent No. 2015489, F41H 1/00).

The disadvantages of body armor are the complexity of the design and the limited time for stretching the shock pulse.

The problem to which the invention is directed, is to increase the reliability of protection and stretching the shock pulse in time.

The essence of the invention lies in the fact that the protective device against mechanical damaging means contains convex elements, one of the surfaces of which has a spherical shape and is supported on the surface to be protected. Convex elements are made of elastic material and are interconnected by jumpers forming ribs from the side facing outward and grooves from the side facing the surface to be protected.

The technical result is achieved in that the protective device includes fragments made of an elastic material in the form of a sheet, consisting of convex elements delimited around the perimeter from the inside by a groove, and from the outside, by a rib and attached to the body of the equipment, and put on in protective clothing in the form vest on a substrate of material providing free sliding of vest fragments.

Figure 1 shows a fragment of a protective device, figure 2 is a section A - A in figure 1, figure 3 is a moment of impact, figure 4 is a fragment of protective clothing, figure 5 is a section B - B figure 4.

The protective device contains fragments 1, consisting of convex elements 2, interconnected by jumpers with the formation of grooves 3 from the side facing the surface to be protected, and ribs 4 facing outward. Elements 2 on one side have a convex spherical part, which rests on the protected surface 5. When used in protective clothing, fragments 6 include convex hollow elements 7 connected by jumpers to form ribs 8 in the outward part and grooves 9 in the part facing the protected surface, and the substrate 10.

The protective device operates as follows. At the time of striking with a mechanical striking means 11, one of the elements 2 of the fragments 1, the element 2, leaning on the convex part on the protected surface 5 of the object’s body, bends, bends or breaks out along the groove line 3 and moves with the striking means 11 on the surface 5 of the object’s body, which destabilizes the damaging means 11 and stretches the shock pulse in time.

When using a protective device in protective clothing at the time the striking agent strikes one of the elements 7, which make up the fragments 6, due to the elasticity of the material in the region of the ribs 8, the elements 7 tilt and destabilize the striking means and move with it along the surface of the substrate 10, entrain other elements 7, which create resistance and stretch the shock pulse in time, which allows you to protect the object from damage.

Convex elements can be made both solid and hollow from elastic materials.

The technical result of using the invention is to increase the reliability of the protection of the object.
