ABSTRACT:
In a blind of the type having a plurality of parallel slats, said slats being simultaneously tiltable to any desired angle to adjust the amount of light admitted through said blinds, an improvement including a flexible tension means, such as a guy wire, along the length of the blind, perpendicular to the slats, and between a headrail and a basebar. The guy wire is tensioned such that the slats are supported and such that their edges are coplanar with each other. Means in the form of a ratchet are provided for maintaining proper guy wire tautness. The blind may be positioned in any orientation and yet continue to function as intended without sagging or drooping. A universal means is provided for adjusting the angle to which the slats are tilted. In this way, a blind positioned at an angle, such as on a ceiling, is as readily adjustable as a blind positioned on a vertical wall.
