Telescopic louvered cover with flexible plastic element

Abstract

Telescopic louvered cover, comprising a flexible plastic element (2) to which at least three identical, mutually displaceable louvers (1) are attached, each louver (1) being made of a single piece of spring steel made of stainless steel with a thickness of 0.3 to 0.5 mm and a rectangular shape, forming a protective surface (a) of the louver (1) from above, wherein one of the longitudinal sides of the louver (1) is bent twice in the direction of the flexible plastic element (2) and the protective surface (a) of the louver (1) transitions by a first fold into an auxiliary surface (c) of the louver (1), which transitions by a second fold into a connecting surface (d) of the louver (1),wherein the protective surface (a) of the lamella (1) has an angle (α) of less than 180° with the auxiliary surface (c) of the lamella (1) and the connecting surface (d) of the lamella (1) has an angle (β) of less than 180° with the auxiliary surface (c) of the lamella (1) and on the other longitudinal side of the lamella the protective surface of the lamella (1) is terminated with a cutting edge which is formed by bending the longitudinal edge of the lamella (1) in the direction of the attachment at an angle (β) of less than 180° to the protective surface.
