Abstract
A roller shade assembly includes a drape bar extending adjacent a rotatably supported roller tube to suspend a portion of a flexible shade fabric windingly received by the roller tube. The drape bar includes a fabric-receiving portion that is shaped along at least a portion of its length to be non-linear so that the suspended portion of the shade fabric defines a curve across its width. The fabric-receiving portion of the drape bar may be continuously curved. Alternatively, the fabric-receiving portion may include substantially straight segments each longitudinally misaligned with adjacently located segments.

A roller shade assembly comprising:
- a rotatably supported roller tube that supports a flexible shade fabric for winding of the shade fabric thereon;
- and
- an elongated bar shaped along at least a portion of its length to be non-linear the elongated bar supported to orient the shaped portion at an angle from the horizontal, the elongated bar having a fabric-receiving portion slidingly receiving the flexible shade fabric and suspending a portion of the flexible shade fabric, the fabric-receiving portion located at a horizontal distance from the roller tube.
A drape bar for use with a roller shade assembly for suspending a portion of a flexible shade fabric, the roller shade assembly including a substantially cylindrical roller tube rotatably supported for winding receipt of the shade fabric by the roller tube, the drape bar comprising:
- an elongated fabric-receiving portion shaped along its length to be non-linear, the fabric-receiving portion defining an upper surface for sliding receipt of the flexible shade;
- and
- end portions connected to opposite ends of the fabric-receiving portion, the end portions adapted for mounting the drape bar to a fixed support such that the fabric-receiving portion is oriented at an angle from the horizontal and extends adjacent the roller tube of the roller shade assembly at a horizontal distance from the roller tube.
