ABSTRACT:
An umbrella that folds in a radial manner and has a canopy supported by a shaft that has its vertical projection located outwardly from the fabric cover. The umbrella shaft extends from its vertical position to an almost horizontal position towards the center of the canopy, forming in effect one of the support ribs. The fabric cover is secured to the shaft by snaps, or a hook and loop fastener. Both ends of the fabric panel are attached to the shaft in a looped manner. The opening of the fabric is looped under the shaft to prevent water entry. Located at the end of the horizontal shaft is a vertical pin representing the center of the umbrella to which a plate pivotally attaches. A plurality of support ribs are pivotally connected to the plate and made of flexible material to prevent breakage during windy conditions. The folding mechanism allows for radial folding of all support ribs to be aligned with the supporting shaft.
