US Patent 8028352 Pool covering apparatus

A pool covering apparatus includes a tube that forms a continuous loop. The tube is positionable around a perimeter edge of the pool. A flexible panel is attached to the tube and covers an area bounded by the tube. The panel covers the pool when the tube is positioned around the pool. The panel has an area dimension greater than an area dimension bounded by the tube. A lift assembly is attached to the tube and the panel. The lift assembly lifts the cover above a plane of the tube.
