Abstract
Cord guide, such as a pulley, and support therefor, for use with a liftable shade, as a Roman shade or a venetian blind. There is provided a pivotally suspended cord guide support for use with a liftable shade which will suspend the cord guide in a pivotal manner so that the pull cords may be held for operation at a substantial angle with respect to the wall without diminishing their effectiveness in operating the shade. Specifically, the cord guide is supported within a generally conventional clevislike structure which has a specially constructed head end adapted for pivotal support on and by a ceiling or wall attachable bracket. With such pivotal support, the clevis and the cord guide carried thereby, while normally hanging parallel with the wall, can be angled away therefrom to permit greater ease in pulling of the shade cords but without diminishing the accuracy or effectiveness of said cords in the operating of the shade. A lock and guides for the shade cords may also be provided if desired.
