Abstract

A retractable awning assembly includes a spring-biased roller assembly, a flexible canopy having an inner edge for connection to a wall and an outer edge secured to the roller assembly, and a pair of arm assemblies supporting opposite ends of the roller assembly and operable to move the roller assembly between a stored position adjacent the wall and a sheltered position spaced from the wall. Each arm assembly has an extendable support arm, a pneumatic cylinder operably connected to the support arm for extending and retracting the support arm, and an extendable rafter arm including a pair of parallel pneumatic cylinders for extending and retracting the rafter arm. The support arm has a pair of laterally spaced apart wheels which are rotatable about a generally horizontal axis, an upper end operably connected to the roller assembly and a lower end pivotably securable to the wall. The rafter arm has an upper end pivotably securable to the wall and a lower end pivotally connected to the support arm. The awning assembly also includes a pair of laterally spaced apart ramps for each support arm and a pneumatic control system for selectively supplying and exhausting pressurized fluid to and from the pneumatic cylinders of the support arms and the pairs of pneumatic cylinders of the rafter arms to move the roller assembly between the stored position and the sheltered position. The ramps are securable to the wall and have engagement surfaces adapted to cooperate with the wheels of the support arms to pivot the support arms about their lower ends when the support arms are extended while in the stored position.
