Abstract
An umbrella comprises a cover having open and closed positions. A hollow pole supports the cover. An operative wind-up assembly for selectively opening and closing the cover includes a mechanism mounted on the pole. A cable extends from the wind-up mechanism through the inside of the pole for activating the cover. Part of the wind-up mechanism includes a rotatable handle with an interiorly positioned spool. One end of the cable is attached around the spool for winding the cable when the handle is rotated to cause opening of the cover.
