Abstract: A retractable awning includes a frame structure, roll bar, and a lead bar supported in cantilever fashion by a series of extendable arms that extend from the frame structure. An awning sheet is connected between the roll bar and the lead bar. When the lead bar is extended outwardly from the roll bar, the sheet awning is unrolled and supplied from the roll bar. Conversely, when the awning is retracted, the lead bar retracts towards the roll bar and in the process, the sheet awning is rolled onto the roll bar. The frame structure, roll bar and lead bar are split into at least two sections with each pair of sections including a coupler for connecting the two sections together.

Abstract: In an awning such as a house trailer or recreational vehicle awning, plural ribs are disposed against the underside of the awning. The ribs run transversely from the wall to the tube which supports the outboard end of the awning; this tube is horizontal, and parallel to the wall. The ribs are flexible, and slightly longer than the distance from the wall to the tube. When the ribs are put into place they acquire an upward bow, which crowns the surface of the awning. This encourages water runoff, decreases wind flapping, and improves appearance. Each rib has two parts for length adjustment. One part has an integral clamp to hold the other part in a fixed position; when the clamp is loosened the two parts can slide relatively. To hold the ribs in position various means may be used, including rib end pockets on the awning, straps, and fingers on one rib end mating with holes in the tube surface.
