ABSTRACT:
A folding umbrella of the type in which a lower section closes upon an upper section, as both these sections close upon the umbrella rod, and wherein this closing movement is automatically achieved, i.e. is the result of articulating or pivotal movement of the umbrella ribs, rather than being movement that must be manually imparted.
