ABSTRACT:
The tension members in a collapsible umbrella are each provided at the opposite ends with upwardly bent loops that are pivotally connected to a stay and an inner end of a joint member so that when the umbrella is turned inside out by a gust of wind, the tension members are caused to bend downwardly and be stably received within the struts to avoid displacement of the joint members. The downward bending of the tension members place same under considerable tension for urging the joint members upwardly when the umbrella slider is pulled downwardly, thereby restoring the umbrella to its original condition. The joint members are further provided with curved upper portions for permitting the umbrella ribs to cluster more closely around the umbrella shaft for storage.
