Abstract
A slimmed rib assembly for multiple-fold umbrella includes: a flat rib pivotally connected with an inner rib and respectively pivotally secured to an upper notch of an umbrella shaft and a runner slidably held on the umbrella shaft, a middle rib having an U-shaped groove and pivotally connected to the flat rib, and a tail rib pivotally securable to the middle rib, with the inner rib having an U-shaped groove recessed therein; whereby upon closing of the umbrella, the flat rib will be received into the U-shaped grooves respectively formed in the middle rib and in the inner rib to greatly minimize the volume of the rib assembly when folded to thereby provide a slim umbrella for convenient storage and handling.
