Publication number: 20040149327Abstract: A windproof umbrella resistant to inversion from the wind and effective in ventilation is disclosed. A frame of the umbrella comprises a hub and upper and lower rings on the shank. A canopy of the umbrella comprises lower, intermediate, and upper canopies all being concentric and in a partial covering relation between any two adjacent ones. Ropes are interconnected between centers at sectors of an upper peripheral edge of the lower canopy and through holes of the upper ring by looping. Hence, lower and upper openings between the overlapped areas of the canopies are formed for air escape when wind caught beneath the canopy assembly applies pressure to an inner surface of the canopy assembly.Type: ApplicationFiled: January 30, 2003Publication date: August 5, 2004Inventor: Ching-Chuan You
