CA 2045471

A windproof umbrella includes a post (14); a plurality of ribs (18) extending outwardly in a radial direction from the upper end of the post; a lower canopy (20) secured on the ribs (18); a plurality of vent holes (34) therethrough; and an upper canopy (36) positioned on the lower canopy (20) and covering all lower vent holes (34). The upper canopy (36) is smaller than the lower canopy (20). Elastic fastening straps (48) secure the upper canopy (36) to the free end portions of the ribs (18) for permitting the upper canopy to elastically lift up responsive to wind. The upper canopy (36) may include at least one vent hole (76) closer to the free ends of the ribs (18) than the lower vent holes (34). A plurality of slits (44) extending inwardly from the outer edge of the upper canopy (36) may be provided, each slit (44) being in line with one rib (18). A channel forming member (57) may be secured to the lower canopy (20) in surrounding relation to each lower vent hole (44) for further preventing entry of water therethrough.

Un parapluie résistant au vent comprend un manche (14), une pluralité de baleines (18) qui s'étendent radialement vers l'extérieur depuis l'extrémité supérieure du manche, une voilure inférieure (20) attachée aux baleines, une pluralité d'orifices d'aération (34) ménagés dans la voilure, un conduit (57) fixé à la voilure inférieure de façon à entourer chaque orifice inférieur d'aération (34) et à empêcher l'eau d'y pénétrer et une voilure supérieure (36) placée sur la voilure inférieure de façon à couvrir tous les orifices inférieurs d'aération. La voilure inférieure (36) comprend au moins un orifice supérieur d'aération (56) plus proche des extrémités libres des baleines (18) que les orifices inférieurs d'aération (34), un bord extérieur et une pluralité de fentes (44) avec une baleine (18). La voilure inférieure (36) est plus petite que la voilure inférieure (20). Des bretelles élastiques de fixation (48) servent à attacher la voilure supérieure (36) aux extrémités libres des baleines (18).
