ABSTRACT:
A garden umbrella with a partial top canopy covering the central area of the umbrella and located on the upper side of the canopy ribs, and an underside outer canopy secured to the underside of the canopy ribs and covering at least the outer ring portion of the canopy ribs not covered by such partial top canopy. The underside outer canopy has canopy rib sleeves formed on its top side and adapted for receiving therein the middle and end tip portions of the canopy ribs. The partial top canopy is secured at its outer ends to the upper side of the canopy ribs and the canopy sleeves such that a deep vent is formed between the partial top canopy and the underside outer canopy for venting wind through the space between the two canopies. In one embodiment, the underside outer canopy has a general ring shape with an opening in the center for further venting of wind and updrafts through the center of the umbrella. Also, the connection of the partial top canopy and the underside canopy respectively on top of and under the canopy ribs and the rib sleeves provides a double canopy link extending around the unbrella thereby stabilizing the ribs from unwanted shifting from side to side in response to wind pressures.
