Abstract
An improved rib linkage joint for an umbrella where the rib linkage includes an inner rib and an inner linking spoke, both hingedly connected to a middle joint, that middle joint being fixed to one end of a middle rib. The inner rib, the inner linking spoke and the middle joint is each in the form of a strut having a U-shaped cross section with the slots thereof facing upward. A flexible middle linking spoke has one end hooked on a pin fixed between the strut side walls of the inner linking spoke adjacent the middle joint. This structure allows easier assembly of the rib linkage joint initially, as well as enhances compactness of the rib linkage when the umbrella is collapsed.
