ABSTRACT:
A self-contained tensioned roller shade system that can be easily installed in an opening, such as a window or a skylight. The roller shade system comprises a free-standing frame, a roller tube rotatably mounted between first and second side channels of the frame adjacent a first end of the frame, and a shade fabric is windingly received around the roller tube. A tensioning cord is operatively coupled between the roller tube and a second fabric end opposite the first fabric end, and is windingly received about the roller tube. A pulley is operatively coupled to the frame adjacent the second frame end and windingly receives the tensioning cord. The tensioning cord is adapted to bias the second fabric end toward the second frame end, the second fabric end of the shade fabric adapted to move between the first and second frame ends as the roller tube is rotated.
