Patent ID: 7740044

Claim:
An awning assembly adapted to be mounted at a structure, the awning assembly comprising: a primary roller having an internal cavity within at least a portion of the primary roller, an opening between the internal cavity and an exterior of the primary roller and a first arresting element, the primary roller adapted to rotate around its longitudinal axis in a first direction and in a second direction opposite to the first direction; a first awning material having a first end and a second end, the first awning material being attached adjacent its first end to the primary roller and wherein the second end is mounted to the structure, the first awning material also being adapted to be unwound from the primary roller when the primary roller is rotated in the first direction and wound onto the primary roller when the primary roller is rotated in the second direction; a secondary roller mounted within the internal cavity of the primary roller substantially coaxially with the primary roller for rotation within the internal cavity around the longitudinal axis of the second roller in the first direction independently of the primary roller and in the second direction selectively independently of the primary roller and together with the primary roller; a second awning material having a respective first end and a respective second end, the second awning material being attached adjacent its first end to the secondary roller, the second end of the second awning material extending through the opening in the primary roller between the internal cavity and the exterior of the primary roller, the second awning material adapted to be unwound from the secondary roller when the secondary roller is rotated in the first direction and wound onto the secondary roller when the secondary roller is rotated in the second direction; a second arresting element attached adjacent the second end of the second awning material and adapted to engage the first arresting element of the primary roller, whereby, upon engagement of the first and second arresting elements, rotation of the secondary roller in the second direction causes the primary roller to rotate in the second direction together with the secondary roller; wherein the first arresting element comprises a shoulder that projects inwardly of the exterior of the primary roller towards an exterior of the secondary roller to form an arresting space between the shoulder and an outermost wrap of the second awning material when the second awning material is wound onto the secondary roller to the maximum extent of the second awning material; and wherein the arresting space between the shoulder and the outermost wrap of the second awning material becomes smaller as the second awning material is wound onto the secondary roller and the shoulder and outermost wrap of the second awning material prevent the passage of the second arresting element.
