Abstract
Abstract A fabric rollup awning for use on travel trailers, mobile homes, residential patios and terraces, and commercial and industrial applications for quick shade from the sun. A pocket at the upper edge of the fabric molding contains a 1/4 -inch nylon cord which is slid through the conventional trailer molding attached to the sidewall of the structure. A front bar roller has a spherical groove which slidably receives a nylon cord located in a pocket attached to the front portion of the fabric awning. Two-piece telescoping spring-loaded rafters extend from the upper end of the fabric awning to the front bar roller and support the same; and uprights are pivotally attached to the ends of the roller and support the same either from the sidewall of the trailer or building or from the ground. Roller end assemblies upon the front bar roller incorporate spring-loaded hexagonal trunnions and ratchet means is associated therewith for rolling the front bar roller up or down.
