A retractable blind or shade assembly for covering a polygonal contoured surface area, includes a retractable covering member (2, 16, 36, 37, 55), a movable member (3, 39, 60') and at least one cord member (9, 43, 44, 58). At least one cord member (9, 43, 44, 58) is provided between its terminal ends with a looped connection (10, 10') adapted to engage the movable member (3, 39, 60') upon a predetermined amount of relative movement between the movable member (3, 39, 60') and the one cord member (9, 43, 44, 58) in one direction, while otherwise relative movement between the movable member (3, 39, 60') and the cord member (9, 43, 44, 58) is independent of one another. The assembly enables the engagement of a further element without obstruction to being guided through openings or around deflecting surfaces and pulley wheels, such as are often part of a blind or shade structure.
