ABSTRACT:
The blind has first pairs of planar members 21,22 hinged together at 23, and second pairs at 25,26 hinged together at 27, the members of one pair being connected to the members of the other pair by connectors 28,29 to form a zig-zag array and operating cords 42,43 pass through apertures 40,41 in the members, the cords passing freely through alternate members and physically engaging the other alternate members so that when longitudinal movement is between the cords 42,43 in one direction the first and second members are folded towards one another and the third and fourth members away from one another and when in the opposite direction the first and second members are folded away from one another and the third and fourth members folded towards one another to give two entirely distinct visual appearances. At least some of the members may be translucent to give an effect similar to that of a venetian blind.
