Abstract
A conventional umbrella has three hooks mounted upon each of its downwardly extending ribs. The first hook is located at the bottom of the rib. The second hook is located at the connection point of the rib and one of the elongated struts used to open and close the umbrella. The third hook is located on the same rib intermediate the first and second hooks. A flexible cable is attached to the first hook, passes or extends through the second and third hooks and is then attached to the center pole of the umbrella.
