ABSTRACT:
A swimming pool cover constructed from a flexible impervious material wherein the leading or forward edge thereof is raised above the pool's surface. The above swimming pool cover is adapted with a longitudinal or lateral beaded side edge which is slidably held within a longitudinal open channel or track cut into a slideway member mounted to the deck or longitudinal margins of a swimming pool. The leading or forward edge of the cover is also beaded or thickened so that it may be received and held within a track or channel fixed to a bowed tubular member. Fixed to either end of the bowed tubular member are pivotally mounted legs having rotatably mounted tandem wheels fixed thereto. To prevent the bowed member from "rolling" after the pool cover has been extended, an outwardly extending stop member is fixed to the outer wall of each end of the tubular member for contacting one of the leg members and thereby limit the bowed member's "rolling" action. A link chain is fixed to the lower ends of each of the legs of the tandem wheels to limit leg extension. To prevent the pool cover from being overly stressed and thereby inadvertently damaged during use, a pair of side gores are inserted along each of the forward side edges of the pool cover to permit it to be raised without causing excessive stress on the forward section of the pool cover. A third gore is provided in the central, forward section of the pool cover for draining the extended pool cover of any water which may collect thereon.
