Abstract:
1. An umbrella with multiple canopy structure, comprising: a shaft; a lower canopy having an opening; an upper canopy having an inner portion and an outer portion, wherein said upper canopy is supported above said lower canopy and over said opening; a first supporting assembly connected to said shaft and said first and second canopies to operably move said first and second canopies between a closed position and an open position, wherein said inner portion of said upper canopy moves with said first supporting assembly; and a second supporting assembly connected to said first supporting assembly within said opening of said lower canopy and connected to said outer portion of said upper canopy for operably and manually moving said outer portion of said upper canopy between a concave position and a convex position while said lower canopy and said inner portion of said upper canopy are retained concavely and such that said outer portion of said upper canopy covers said opening when in said concave position to restrict air passage through said opening and such that said outer portion of said upper canopy exposes said opening when in said convex position to permit air passage through said opening, wherein said second supporting assembly is adapted to retain said upper canopy in said convex position until manually reverted back to said concave position; wherein said first supporting assembly includes: a plurality of first ribs each having an inner end and an outer end, said inner end of said first ribs being retained along an upper end of said shaft and said outer end of said first ribs being retained adjacent a first peripheral edge of said lower canopy; a plurality of stretchers each having an inner end and an outer end, said outer end of said stretchers being pivotally connected to said first ribs between said inner and outer ends of said first ribs; and a runner movable along said shaft, said inner end of said stretchers being pivotally connected to said runner, wherein said operable movement of said runner causes said stretchers and said first ribs to move and thus adjust said lower canopy between said closed position and said open position; wherein said second supporting assembly includes: a plurality of second ribs each having an inner end and an outer end, said inner end of said second ribs being retained upon said first ribs between said inner and outer ends of said first ribs and said outer end of said second ribs being retained along a second peripheral edge of said upper canopy; wherein said inner portion of said upper canopy retains a shape of said first ribs and wherein said outer portion of said canopy retains a shape of said second ribs, wherein said second ribs adjust from said concave position to said convex position.
