Abstract

A shade (10) includes slats (20) that are arranged in an up and down direction. One or more slat(s) (21) forming a part of the slats, which is located above in the up and down direction, includes a transparent portion that enables visible light to transmit through the slat. A traveling direction of light transmitting through the transparent portion is bent.

First claim

The invention claimed is:

1. A shade comprising a plurality of slats that are arranged in an up and down direction, wherein at least one first slat of the plurality of slats, which is located in an upper portion of the shade, includes transparent first portions extending in a first direction that is in nonparallel with respect to an up-and-down direction, second portions arranged alternately with the first portions in a second direction that is in nonparallel with respect to the first direction, and a base portion supporting the first portions and the second portions, wherein the base portion is integrally formed with the first portions, wherein the first portions enable visible light to transmit through the at least one first slat, and the at least one first slat bends upward a traveling direction of the light transmitting through the transparent first portions, wherein each second portion includes a resin material and a heat absorbing agent dispersed in the resin material, wherein the second portions have a different refractive index from that of the first portions, wherein the at least one first slat has a curved shape, and the second direction extends along a curved plate surface of the at least one first slat, and wherein a width along the second direction of the second portions decreases away from a convex surface side of the curved slat toward a concave surface side of the curved slat.

2. The shade according to claim 1 , wherein at least one of the first portions or at least one of the second portions are colored.

3. The shade according to claim 1 , wherein the at least one first slat includes a unit prism that bends a traveling direction of the light by reflection or refraction.

4. The shade according to claim 1 , wherein an inclination of the at least one first slat located in the upper portion of the shade is operable independently from an inclination of at least one second slat located in a different portion of the shade.

5. The shade according to claim 2 , wherein
an inclination of the at least one first slat located in the upper portion of the shade is operable independently from an inclination of at least one second slat located in a different portion of the shade.

6. The shade according to claim 3 , wherein
an inclination of the at least one first slat located in the upper portion of the shade is operable independently from an inclination of at least one second slat located in a different portion of the shade.

7. The shade according to claim 4 , wherein the different portion of the shade is a lower portion of the shade.

8. The shade according to claim 1 , wherein the at least one first slat includes a substrate layer, and a light control layer supported on the substrate layer, wherein the substrate layer and the light control layer extend along a plate surface of the at least one first slat.

9. The shade according to claim 8 , wherein the transparent portion that enables visible light to transmit through the at least one first slat, and bends a traveling direction of the visible light transmitting through the transparent portion, enables the visible light to transmit through the at least one first slat in a thickness direction thereof.

10. The shade according to claim 1 , wherein at least one second slat of the plurality of slats, which is located in another portion of the shade spaced away from the at least one first slat, includes an opaque portion that shields light from passing through the at least one second slat.

11. The shade according to claim 1 , wherein at least one of the second portions includes a substantially planar bottom surface with opposing first and second ends, a first side surface projecting at a first acute angle from the first end, the first acute angle having a first slope, and a second side surface projecting at a second acute angle from the second end, wherein the second side surface has a second slope that is different from the first slope, and wherein the first side surface and the second side surface meet to define an obtuse angle.
