Patent number: 6598612Abstract: An easily deployed ridge pole is used, in combination with standard awning deployment hardware, to change the shape of the canopy fabric of an extended retractable awning. The ridge pole engages the underside of the awning fabric to impart a Mansard shape to the canopy. This shape incorporates first and second planes of canopy fabric wherein the plane closest to the RV has a less steep pitch than the plane furthest from the RV. The shape has airfoil qualities which stabilize the effects of high wind velocities on the awning. The shape also provides room under the relatively flat plane for doors under the awning to open without engaging the awning fabric. The ridge pole is supported by struts which in some embodiments provide foundations for fabric stabilizing clamps that are affixed to loose edges of canopy fabric.Type: GrantFiled: November 21, 2000Date of Patent: July 29, 2003Inventor: James R.
