ABSTRACT:
A pocketable folding umbrella includes: a slim upper notch secured on an upper portion of a central shaft; a slim lower runner slidably held on the central shaft; a plurality of extremity rib sets respectively radially pivotally secured to two extremity portions of the upper notch and the lower runner, a plurality of flat-side rib sets respectively universally pivotally secured to an upper gradational platform protruding downwardly from the upper notch and a lower gradational platform protruding upwardly from the lower runner, and an umbrella cloth secured with the rib sets, whereby upon folding of the umbrella from an opened state, the flat-side rib sets will be inwardly folded from an outer biased position towards a flat side portion of the upper gradational platform of the upper notch and towards a flat side portion of the lower gradational platform of the lower runner as accompanied with a radially folding of the extremity rib sets on the two extremity portions of the upper notch and the lower runner for greatly minimizing the dimensions of the upper notch and the lower runner for reducing the volume of the folded umbrella for a convenient carrying and storage when stored in a pocket or a handbag.
