ABSTRACT:
A plurality of support bars are provided with at least one of the bars being movable relative to another of the bars. A plurality of separate webs of pleated material are provided with the opposite edges of each of the webs being secured to adjacent bars. A plurality of tensioning cords are provided, each of the cords extending between adjacent bars to support an associated web. Each of the tensioning cords is tensioned by spring means. When the blind is in closed position, the bars are spread apart and the webs are flattened to define a plurality of sections. The outer peripheries of the pleats of each section lie generally in a plane, the plane of each of the sections being disposed at an angle to the plane of an adjacent section so that each of the planes defines a chord of a curve.
