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 each having, in alignment in a certain direction, a plurality of sunshade members arranged in a plurality of tiers and 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 of the plurality of light-shielding surfaces provided therebehind, wherein some of the sunshade units are provided at higher positions than other sunshade units of the sunshade units in the vertical direction such that air passing through the plurality of sunshade members arranged in a plurality of tiers of one of said some of the sunshade units is released above or below an adjacent sunshade unit of the other sunshade units without flowing into the plurality of sunshade members of the adjacent sunshade unit and such that cool air which passes the one of said some of the sunshade units flows into the plurality of sunshade members of the adjacent sunshade unit.

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 a height of the legs supporting a first of said plurality of groups being different from a height of the legs supporting another group of said plurality of groups.
