ABSTRACT:
A swimming pool cover includes a plurality of sheets arranged in accordion fashion with one of the sheets being attached to the wall of the pool. Hollow rigid pipes are provided for the sheets whereby the sheets may float when the pipes are filled with air. When the pipes are filled with water, the sheets sink and assume an accordion type arrangement thereby permitting use of the pool.
