Abstract
Pool covers embodying the invention are formed of a very dense mesh material which ensures substantially one hundred percent shade while allowing water to pass uniformly through the cover and which is adequately strong to support the weight of an adult. The pool cover is formed of plastic fibers which are interwoven to form a dense mesh which is then subjected to a pressure and heat cycle to ensure that the resultant material has the requisite properties for allowing water to pass through at a desired rate (e.g., 0.1 to 5 gallons per square foot per minute) while blocking light (e.g., 100% shade). Thus, a self-filtering safety pool cover is formed which allows for water to pass through uniformly across its surface while blocking sunlight.
Claims7
A pool cover comprising:
- a sheet of plastic material formed of plastic fibers which are interwoven, with a first set of fibers lying in a first direction having a first density and a second set of fibers, lying in a second density, lying in a second direction, generally perpendicular to the first direction, said first and second set of fibers forming a high density mesh pattern enabling water to pass through the pool cover while blocking light from passing through the cover, at approximately 100% shade as defined in the ASTM standard whereby water can not accumulate on top of the pool cover and light is blocked to prevent the growth of algae in the water within the pool.
The pool cover as claimed in claim, 1 wherein the fibers are forming the pool cover are subjected to a pressure cycle and heat to modify the characteristics of the material to allow water to pass through the material while blocking light.
