Abstract
The umbrella frame is provided with a movable yoke at the upper end and a stationary yoke at an intermediate point. Ribs are pivotally mounted on the movable yoke and struts are pivotally mounted on the fixed yoke while being pivotally mounted to intermediate points on the ribs. A downward movement of the upper yoke causes the ribs to splay outwardly so as to open the umbrella. An articulated lever and link arrangement is connected to one rib and strut unit so that actuation of the lever causes the upper yoke to be pulled downwardly to open the umbrella. Passage of the lever by a bottom dead center position effects locking of the movable yoke in the lowered position.
