ABSTRACT:
A folding umbrella having a telescopic stem which is connected to a crown at the top and at the bottom to a handle pivotally supporting a radius hand-grip, ribs and stretchers are provided for extending or collapsing the roof of the umbrella, a runner is slidable along the stem for actuating the ribs and stretchers through interposed links and auxiliary links, a lever is co-operative between the radius hand-grip and an elongated runner slide which is slidably arranged within the runner and around the stem and which carries at the upper end a notch member to which the struts, pivoted to the links or stretchers, are pivotally connected. The umbrella, while held in one hand, can be conveniently extended to convenient length, opened and closed by manipulating the radius hand-grip with the thumb and/or fingers in a direction transverse to the stem and also can be conveniently collapsed to reduce the length and retained in locked position by pushing the handle toward the crown while the top of the stem is supported or propped against any object.
