WIPO Patent Application WO/2018/079709
Kind Code:

Abstract:
This dimming blind is provided with: a plurality of slats arranged in the vertical direction; and a slat rotation and lift operation part which opens and closes each of the plurality of slats by rotating the slats by a predetermined angle around the horizontal axis, and moves the plurality of slats up and down. At least a portion of the plurality of slats are asymmetric slats each having an asymmetrically bent or curved shape in a cross-section perpendicular to the longitudinal direction of the slats. The asymmetric slats are each provided with a first plate part and a second plate part, wherein the first plate part corresponds to a long side of a cross-sectional shape perpendicular to the longitudinal direction, and the second plate part corresponds to a short side of said cross-sectional shape. When the plurality of slats are folded, the slat rotation and lift operation part lifts the plurality of slats while keeping the first plate part of the asymmetric slat oriented downward.
