ABSTRACT:
A guided cord system for a slatted blind assembly having a plurality of slats interposed between a movable bottom rail and a fixed headrail. The system has at least one lift cord that extends from an end of the bottom rail around a turning point fixed to a frame structure and positioned near the end of the bottom rail opposite the plurality of slats. The lift cord then extends to a guide means associated with the headrail and then back to the bottom rail to which it is connected to form an operating loop. The blind is retracted when the cord moves in one direction and extended when moved in the opposite direction.
