ABSTRACT:
A covering for an architectural opening in the form of a Venetian blind includes a plurality of supporting ladders for horizontally disposed but vertically spaced slats with the ladders including vertically extending spaced guide cords and interconnecting rungs at vertically spaced locations along the guide cords. The rungs support associated slats in a horizontal orientation and the slats are connected to the rungs so that when the guide cords are shifted vertically relative to each other causing the rungs to tilt, the slats are positively moved between a horizontal disposition and a substantially vertical disposition in which a light blocking seal between the slats is established.
