According to the claimed device, at least one stiffening rib 2 located inside the housing 1 made of the same polymer is introduced into the shading element (Fig. 1) of the anti-glare screen containing the housing 1 made of a hollow (Fig. 1-9) of a polymer material the material of which the housing 1 is made, with its connection with the inner wall 3 of the opposite sides of the housing 1 (Fig. 1-9). The stiffener 2 is located longitudinally relative to the smallest transverse dimensions of the housing (Fig. 2-9). The housing 1 is provided with a cover 4.

The stiffener 2 can be made of at least two plates (Fig. 3, 4, 7, 9).

The stiffener 2 in cross section can be made zigzag (Fig. 5, 6, 8), while its bends are connected to the inner wall 3 of the housing 1.

In addition, the housing 1 in cross section AA can be made rectangular with beveled (Fig. 3) or rounded corners (Fig. 2).

The housing 1 in cross section AA is made elliptical (Fig. 4, 5).

The housing 1 (Fig. 6, 7) in the indicated cross section can be made rhomboid, one diagonal of which is smaller than the other.

The housing 1 (Fig. 8, 9) in the aforementioned cross-section can be made oval-shaped with sharp angles in the region of the vertices of a long diagonal.

The housing 1 (Fig. 1) may be provided with a cover 4 connected to its wall by a weld or adhesive layer 5.

Case 1 (Fig. 1-9) is made of a polymeric material - polyvinyl chloride (PVC), polyethylene (PE), polystyrene (PS), polypropylene (PP), polycarbonate (PC).

The shading element (Fig. 1-9) of the anti-glare screen works as follows.

Due to the introduction of at least one stiffener 2 located inside the housing 1, made of the same polymer material from which the housing 1 is made, and the connection of the rib 2 with the inner wall 3 of the opposite sides of the housing 1 (Fig. 1-9) is possible with the same wall thickness of the housing 1 significantly (as studies have shown by at least 15%) to increase wind resistance and resistance to shock.

The shading element is formed not by blow molding, as in the closest analogue, but by extrusion of profile (molded) products, therefore it is possible to expand the range of manufactured products, and to obtain parts of any length (without requiring replacement of molds), by changing the extrusion head - arbitrary profiles of parts (Fig. 2-9), various types and sizes required. The housing 1 in cross section AA can be made rectangular with beveled (Fig. 3) or rounded corners (Fig. 2), ellipsoidal (Fig. 4, 5), diamond-shaped (Fig. 6, 7), oval-shaped with sharp corners in the region of the vertices of a long diagonal (Fig. 8, 9), as well as combined or any other form, for example in the form of a dumbbell.

Since the stiffener 2 is not located outside the housing 1, but inside it, it is easy to clean a smooth outer surface. The longitudinal stiffening rib 2 on the outer surface of the wall of the housing 1 counteracts only the bending of the plate (http://www.ekodorsnab.ru/magazin/folder/protivoosleplyayuschie-ekrany/). In the claimed device, because the stiffening rib 2 is located and connected to the inner wall 3 of the housing 1, it both prevents bending and also serves as a kind of shock absorber, which improves shock resistance and wind resistance.

The increase in the number of plates (Fig. 3, 4, 7, 9) for stiffener 2 further improves wind resistance and impact resistance. The implementation of the stiffening ribs 2 in cross section zigzag (Fig. 5, 6, 8) further improves the cushioning properties of the housing 1.

Various means can be used to fasten the shading element to the support, for example, such as in the indicated analogues.

Polymer materials commonly used for molded parts can serve as materials for the extrusion of profile products of the housing 1 together with rib 2 - polyvinyl chloride (PVC), polyethylene (PE), polystyrene (PS), polypropylene (PP), polycarbonate (PC). Since the shading element is made by extrusion of profile (molded) products, it may be necessary to produce a cover 4 connected to the wall of the housing 1 by a weld or adhesive layer 5 (Fig. 1).

The most successfully declared "Shading element of the anti-glare screen" is industrially applicable for the arrangement of unlit roads to protect from the blinding effect of light in the dark during the traffic of oncoming cars.
