ABSTRACT:
A blind having an interior side and an exterior side and having a plurality of elongated slats is disclosed. The slats are made of a flexible and generally resilient polycarbonate material having selected light-transmitting qualities and superior optical clarity. Each slat has a generally V-shaped transverse cross-sectional configuration in which a first portion and a second portion of the slat correspond to the two sides of the V, intersecting at an angle of 90.degree. to 160.degree.. The slats are suspended in parallel relation, the slats being rotatable about their longitudinal axes between an inwardly facing position, in which the upper surfaces of the slats are presented at the interior side of the blind with the first portions of the slats substantially co-planar, and an outwardly facing portion, in which the upper surfaces are presented at the exterior side of the blind and the second portions of the slats are substantially co-planar. The slats are held at a distance from each other such that when the slats are in one of the inwardly facing and outwardly facing positions, the portions of the slats not then co-planar extend sufficiently far toward the slat immediately adjacent thereto as to overlap the immediately adjacent slat, to prevent the passage of light in a direction generally normal to the co-planar portions of the slats without that light being interrupted by the slats.
