## Abstract

To provide sunshade structure which hardly deteriorates its sun-shading performance even in time zones or seasons which are not time zones or seasons when sunlight is intense. A sunshade 80 including a plurality of sunshade blocks 52 having arranged thereto, in alignment in a certain direction, a plurality of sunshade members having a plurality of light-shielding surfaces and a plurality of gaps three-dimensionally arranged therein, and being structured so that, when observed from a predetermined light-shielding angle, the gaps are seen to be substantially shielded by respective light-shielding surfaces provided therebehind, and the sunshade members being formed by using a plurality of curved circular members 50 produced by curving circular or oval plate materials, arranging the curved circular members 50 such that the respective curved directions are aligned, and coupling the mutual ends with each other.

## Claims

### Claim 1

A sunshade including a plurality of sunshade blocks having arranged thereto, in alignment in a certain direction, a plurality of sunshade, members having a plurality of light-shielding surfaces and a plurality of gaps three-dimensionally arranged therein, and being structured so that, when observed from a predetermined light-shielding angle, the gaps are seen to be substantially shielded by respective light-shielding surfaces provided therebehind, and the sunshade members being formed by using a plurality of curved circular members produced by curving circular or oval plate materials, arranging the curved circular members such that the respective curved directions are aligned, and coupling the mutual ends with each other.

### Claim 2 (depends on 1)

The sunshade according to claim 1 further comprising:
a plurality of sunshade units configured by assembling the sunshade blocks to a frame material with respective curved concave faces being in alignment in a certain direction; and
support structure which supports the sunshade units at a predetermined height from the ground.

### Claim 3 (depends on 1)

The sunshade according to claim 1 further comprising: a plurality of normal units configured by assembling the plurality of sunshade blocks to the frame material with respective curved concave faces being in alignment in a certain direction;
a plurality of inverted units configured by assembling the plurality of sunshade blocks in a reversed manner to the frame material; and
a support structure which supports the respective normal units and inverted units at a predetermined height from the ground,
the normal units and inverted unit being arranged alternatively on the support structure.

### Claim 4 (depends on 2)

The sunshade according to claim 2 further comprising an inclination means for mounting and securing the respective sunshade blocks between the frame material and support structure at a predetermined inclination angle relative to the ground.

### Claim 5 (depends on 3)

The sunshade according to claim 3 further comprising an inclination means for mounting and securing the respective sunshade blocks between the frame material and support structure at a predetermined inclination angle relative to the ground.
