Abstract
A wind resistant umbrella comprises a fan-like canopy constructed of sheets of metal or synthetic polymeric resins, which is attached to a central supporting rod.
Claims9
A wind resistant umbrella, which comprises;
- A. a canopy, which comprises
- 1. a plurality of independent, elongate sheets assembled together movably in the plane of a vertical stack, each sheet having
- (a) a first end having a first predetermined width;
- (b) a second end having a second predetermined width;
- (c) a sheet body extending between the first and second ends;
- (d) a body upper surface;
- (e) a body lower surface;
- (f) a peripheral edge defining the outer boundary of the body and the first and second ends together, said peripheral edge including a leading edge and a trailing edge, said peripheral leading and trailing edges extending between the first and second ends at opposite outer boundaries of the body;
- and
- (g) an axial line perpendicular to the plane of the vertical stack, passing through a point adjacent to the first ends and distal to the second ends of the assembled sheets;
- said assembled sheets being fixed together along the axial line, in a first position wherein the respective leading edges and trailing edges of the stacked sheets are in substantial vertical alignment;
- a plurality of sheets in the first position being free to pivot around the axial line to a second position wherein the respective leading edges of each sheet adjacent the second ends substantially covers the trailing edge of an adjacent sheet in the stack;
- B. a rod positioned on the axial line, for supporting the canopy, and having
- (a) a first end adjacent to the first ends of the stacked sheets;
- (b) a second end distal to the first ends of the stacked sheets;
- and
- C. means for attaching the rod to the first ends of the stacked sheet assembly, whereby the sheets are movable between the first and second positions;
- and
- D. handle means mounted on one of said sheets, for moving stacked sheets from the first to the second position.
