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. A crank mechanism is connected to the upper yoke via a cord so that upon cranking of the crank mechanism in one direction, the upper yoke is pulled downwardly to open the umbrella. A clutch assembly is also provided in the crank assembly to lock the crank assembly against the weight of the ribs and cover while allowing a reverse rotation of the crank mechanism under a manually applied force to permit the umbrella to close under the weight of the ribs and cover.
