Embodiment Construction

[0022] Referring now to FIG. 1, a pool cover 1 is seen in cross section. The pool cover is shown as floating on the water 2 within a swimming pool 3 or other small body of water. Although the present application is directed to a swimming pool cover, it could also be used for other pools such as fishponds, or decorative pools.

[0023] The pool cover includes a plastic upper film 5 and a plastic lower film 8. The two films are joined together to form air pockets 10 which contain air therein so that the cover will float on the water. Sealed land areas 11 are formed between the air pockets where the films maybe sealed to each other.

[0024] The films are generally made of essentially transparent plastic films such as vinyl or olefin, e.g., polyethylene and polypropylene, or acetate films. Films may contain a small amount of tint for cosmetic purposes, such as a light blue tint. The film may also include infrared absorbent material 15 in order to provide heat to the water. Light absorbing ...

Abstract

A swimming pool cover which retards algae growth. Two films are sealed together so as to create air pockets which allow the pool cover to float on the surface of the water. One or both of the films contains a material which prevents the passage of light in those wavelengths which are necessary for algae growth, especially 350-500 nm and 600-700 nm. The material may either be a dye which has a color associated with that wavelength or may be a transparent material which removes those wavelengths of light. The remaining wavelengths of light are allowed to pass through the cover in order to heat the water but not cause algae growth. Additionally, the cover can be made by mixing light absorbing material into the plastic before making the film for the pool cover or may be made by applying a layer of light absorbing material to the film.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates generally to solar cover for covering a swimming pool and more particularly to a floating solar cover for a pool which blocks radiation necessary for algae growth. The invention further relates to a method for making a floating solar cover for a pool which blocks radiation necessary for algae growth. [0003] 2. Description of the Background [0004] Swimming pools are enjoyed in many homes as a source of recreation and as a form of exercise. However, unless a pool heater is provided or a structure built around the pool, it is difficult to utilize the pool in seasons other than summer. In order to extend the usable time of the pool, swimming pool covers have been developed to prevent the loss of heat when not in use. In particular, one type of pool cover involves a plastic device with air pockets which cause the cover to float on the surface. The air pockets then act as insulation and prevent evap...
