Abstract
A liftable window closure, such as a Venetian blind or Roman shade, is lifted and held in place by two or more lifting cords, each of which is wrapped and unwrapped from a section of a spool. The spool is in turn rotated by a single pull cord, which is held in place by a brake mechanism. Each lifting cord is guided onto its spool section by a guide structure directing the cord to a central part of the spool section. A housing extends across the top of the liftable window covering, with the lifting cords extending within the housing and downward through the window covering. In a Venetian blind, a mechanism for tilting the slats extends above the lifting cords, which are held downward by the guide structure.
