SUNSHADE

Abstract

To realize a technique that allows for uniformly exhibiting performance without causing partial degradation of performance even when forming a large-scale sunshade with a large area. A sunshade 76 including a plurality of sunshade units (normal units 66, inverted units 75) having assembled thereto, in alignment in a certain direction, a plurality of sunshade members 50 having a plurality of light-shielding surfaces and a plurality of through-holes three-dimensionally arranged therein, and being structured so that, when observed from a predetermined maximum light-shielding angle, the transmitted light beams are seen to be substantially shielded by respective light-shielding surfaces provided therebehind, with some of the sunshade units being provided at higher positions than other sunshade units in the vertical direction.

Claims

1. A sunshade comprising a plurality of sunshade units having assembled thereto, in alignment in a certain direction, a plurality of sunshade members having a plurality of light-shielding surfaces and a plurality of through-holes three-dimensionally arranged therein, and being structured so that, when observed from a predetermined maximum light-shielding angle, the transmitted light beams are seen to be substantially shielded by respective light-shielding surfaces provided therebehind, wherein some of the sunshade units are provided at higher positions than other sunshade units in the vertical direction.

2. The sunshade according to claim 1, wherein the sunshade units are divided into a plurality of groups, each sunshade unit is supported by separate legs for each group at a position separated from the installation surface by a predetermined distance, and height of some of legs supporting respective groups being different from height of legs supporting other groups.
