Patent abstract
The umbrella is constructed with a frame that allows one rib to be manually lifted in order to open the umbrella and allows a manually applied force to be placed on the cover between two adjacent ribs in order to close the umbrella. Mechanical cranks and the like are eliminated. In one embodiment, rods are added to the struts to weight and maintain the lower movable yoke in the open condition of the umbrella. In another embodiment, the tension in the cover maintains the upper movable yoke in the open condition of the umbrella.
