  • Floatable cover capable of partially or fully covering swimming pools
    Patent number: 4122561
    Abstract: An easily removed or installed cover for swimming pools consists in one form of a cover sheet of flexible sheet material capable of assuming an arched configuration having a periphery in the general shape of the pool. An inflatable air tube is dependently attached by an intermediate supporting wall to the underside of the cover sheet perimeter. The exhaust of a low pressure blower is connected to the air tube by a flexible link of buoyant tubing. The tubing extends beneath the cover sheet from one side of the cover to exhaust air into the air tube on the opposite perimeter. A second low pressure air blower is connected by a second tube to the cover sheet to exhaust air underneath the cover. An apron forming an extension of the cover sheet extends over the edge of the pool and includes provisions for securement to the pool structure.
