ABSTRACT:
A round rim umbrella where the rim members and their connecting hinges form a hoop without pointed projections with a center shaft construction involving a center rod within a hollow shaft and a sliding member fixed to the center rod through a slot in the hollow shaft. The strut structure is such as to allow the canopy to fold upward so that two bare rim pivotal connections act as tips of a walking stick without damage to the fabric of the umbrella.
