Abstract

An awning assembly which is particularly suited for recreational vehicles includes a pair of telescoping support arm assemblies and a pair of folding rafter arm assemblies. A roller is rotatably supported by the support arm assemblies, and an awning is wound and unwound on the roller. Each of the telescoping support arm assemblies includes inner and outer telescoping arms and a cable which is connected to the arms and to the roller for extending the telescoping arms when the roller unwinds the awning. Each of the folding rafter arm assemblies includes a pair of pivotally connected rafter arms, a latch pin for locking the rafter arms in an extended position, and a latch release which enables the rafter arms to pivot when the awning is wound up.
