Sheet curtain with vertical blind actuating mechanism

In combination, an integral, flexible, translucent yet untransparent, sheet curtain, defining a width and having a substantially straight, top edge section, means for suspending said curtain spacedly over ground by said top edge section thereof, means for biasing said curtain into a generally wavy configuration about its said width, whereby a plurality of first, generally open, vertical pockets are defined successively about said curtain width, each one of said sheet curtain first pockets defining a sheet curtain section base and two generally parallel sheet curtain section side legs, and means for tilting in unisson said sheet curtain section side legs from a first limit position, in which said side legs are generally orthogonal to said curtain section bases and said first pockets are generally open, through an intermediate position, in which said side legs are oblique relative to said curtain section bases and said first pockets are partially closed, to a second limit position, in which said side legs are generally parallel to said curtain section bases and edgewisely abut in successive pairs against one another and said first pocket becomes generally closed;

• wherein said tilting means consists of a number of rigid, polygonal, flat members, each polygonal member being freely engaged into a curtain sheet second, generally closed pocket defined by a pair of adjacent sheet sections from two successive said first pockets, each said second pocket being located at the top edge portion of said curtain far away from the bottom edge portion thereof so that most of said curtain sheet hangs freely beneath said polygonal members, each said second pocket defining top seat means against which edgewisely bears a corresponding said polygonal member, and means for supporting said polygonal member over ground and for pivoting same about a vertical axis;
• wherein said polygonal member includes a few peripheral bores spaced from one another, said supporting means including a plurality of hook members destined to slidingly engage a horizontal track, said horizontal track of the type to be anchored horizontally over a window frame to be concealed by said curtain, each said hook member destined to engage a selected one of said bores from a corresponding one of said polygonal members.
