A wind resistive umbrella comprising:
- (a) handle means for gripping and manually carrying the umbrella;
- (b) a central staff connected to the handle means on one end and extended to an apex on the other having sufficient structural integrity to maintain its relative shape in a windy environment;
- (c) a plurality of ribs distended radially from said staff near the apex in a pivotal manner, said ribs having an extended end opposite that of the staff;
- (d) a plurality of struts rotatably connected to said ribs in between the apex of the staff and the rib distended end, further said strut having strut sliding means surrounding said staff with the struts pivotally attached between the rib and the sliding means such that when slid upward toward the apex, the ribs extend outwardly as urged by the struts creating an extended framework;
- (e) a canopy covering the framework secured to each of the radially extending ribs of such a size as to be held in tension by the ribs in an open position with the strut sliding means upward relative to the apex, for repelling rain;
- (f) said canopy having an air relieving opening in the center thereof radially adjacent to said central staff and spaced evenly therefrom, allowing air to be relieved from the umbrella when wind gusts create a pressure differential on said canopy inside and outside surface;
- (g) an air escape cover having canopy attaching means overlaying the air relieving opening in said canopy allowing air to escape from the umbrella through the opening while still maintaining the watershedding ability thereof;
- (h) a movable ring slideably encompassing the apex end of said central staff having said cover centrally joined thereupon as part of the attaching means allowing the cover to move upwards under the elevated pressure of the wind creating a plurality of vents between the canopy and the cover equalizing the pressure differential allowing the umbrella to resist the wind;
- (i) a plurality of resilient axial cover support straps having connecting means affixed on one end to said movable ring, and on the other to said ribs and canopy also connecting the ribs, canopy, and said cover periphery to the middle of the strap creating a reinforcement between the cover, canopy, and ribs assisting in structurally maintaining the integrity of shape of the umbrella when subjected to differential pressure on the canopy inside and outside caused by the wind;
- and,
- (j) a plurality of radial canopy support straps having connecting means joined at the intersection of the canopy and the ribs in a continuous circle assisting in structurally maintaining the integrity of a convex shape of the umbrella in the presence of wind.
