ABSTRACT:
An umbrella which has a handle (20), for gripping, attached to a staff (22) and a number of ribs (26) pivotally connected to the staff, each having a strut (28) rotatably joined therebetween. A canopy (32) having an opening (34) in the center covers the ribs, also a cover (36), larger in diameter than the opening, overlays the canopy creating a water shedding shield. A movable ring (38) attaches the cover to the staff allowing vertical movement of the cover. The cover is reinforced with straps (40) and the inside of the canopy is also reinforced with at least a pair of radial straps (46). The umbrella relieves the air inside when the pressure differential between the inside and outside is increased due to the wind billowing the cover upwardly on the ring, exposing a series of vents between the ribs at the interface of the cover to the canopy expelling the air readily thereby protecting the umbrella from turning inside out.
