  • Patent number: 5896908
    Abstract: An awning extension and retraction apparatus is disclosed. The apparatus is adaptable to being powered by an electrical motor if desired. Left and right support arms are carried by a low position on a supporting wall, and provide telescoping inner and outer support arms. These arms move from a vertical orientation when the awning is retracted, to an angular position when the awning is extended. Hinged left and right rafter arms are carried by an upper position on a supporting wall, and provide an inner rafter arm adjacent to the supporting wall, and an outer rafter arm connected to a roller tube supporting the awning fabric. The inner and outer rafter arms are connected at a mid-point by an elbow joint allowing them to extend from a folded position when the awning is retracted to an extended, locked position when the awning is extended.
