Vertical louver type window drape

Claim 1

In combination with an apparatus for supporting and controlling the rotary and linear movement of a window covering including an elongated horizontal mounting member having a plurality of carriages movably supported thereon, each of said carriages having a rotatable depending supporting member and a vertical louver depending from each supporting member, first control means for effecting linear movement of said carriages and louvers longitudinally of said mounting member and second control means for effecting simultaneous rotary movement of each of Said supporting members and louvers, each about a respective vertical axis, the improvement in said window covering which comprises a unitary flexible drape panel secured to said louvers at spaced intervals at least along the respective top edges thereof to provide alternate generally stiff and generally flexible panel sections with the planar surfaces of said drape panel and louvers being contiguous, said first and second control means being manually operable to selectively move said louvers to open light transmitting position wherein said generally stiff panel sections are arranged in parallel relation normal to the longitudinal axis of the mounting member and spaced from each other longitudinally of the mounting member, with the flexible panel sections between adjacent louvers being disposed alternately on opposite sides of the longitudinal axis of the mounting member in draped configuration, said first and second control means being operable to selectively move said louvers to closed light impeding position wherein said generally stiff panel sections are disposed in overlapping generally co-planar relationship and generally parallel to the longitudinal axis of the mounting member.
