Abstract

A water-cooled lounging pad having circular top and bottom sheets of flexible plastic material to be lain upon by a person obtaining a suntan, a heat seal joining the top and bottom sheets at their peripheries to form a flattened circular waterproof closure capable of retaining a body of water therein, and valve means in one of the sheets formed for slectively admitting a desired quantity of water into the enclosure and for retaining the body of water in the enclosure and for discharging desired quantities of water from the enclosure, the diameter of the pad is 7 feet 6 inches and it is 10 to 15 inches high at the center. The material is white ultraviolet-stablized vinyl sheet of 20 mil thickness substantially opaque to sunlight. The method provides a circular peripheral seal from a fixed work station by supporting the vinyl sheets on a table rotatable about a central axis.

Claims

1. A water-cooled lounging pad, comprising

a circular top sheet of solar heat reflective flexible plastic material adapted to be lain upon by a person obtaining a suntan,

a circular bottom sheet of flexible plastic material substantially coextensive with said top sheet,

a heat seal joining said top and bottom sheets at their peripheries to form a flattened circular waterproof enclosure capable of retaining a body of water therein, and

valve means in one of said sheets formed for selectively admitting a desired quantity of water into said enclosure and for retaining said body of water in said enclosure and for retaining said body of water in said enclosure and for discharging desired quantities of water from said enclosure, said top sheet being of substantially white color for reflection of the sun'"'"'s rays so as to avoid solar heating of said body of water whereby said body of water exerts a cooling effect on the portions of the body of said person in contact with said top sheet.

2. A water-cooled lounging pad as described in claim 1, and wherein said top sheet also is substantially opaque to passage of sunlight therethrough so as further to avoid solar heating of said body of water.

3. A water-cooled lounging pad as described in claim 2, and wherein said bottom sheet is also of substantially white color and substantially opaque to passage of sunlight therethrough whereby inversion of said water-cooled lounging pad also provides a water-cooled upper lounging surface.

4. A water-cooled lounging pad as described in claim 1 and wherein said heat seal is provided at confronting faces of said circular top and bottom sheets at their peripheries.

5. A water-cooled lounging pad as described in claim 1, and wherein said flexible plastic material of said top sheet comprises ultraviolet-stabilized vinyl.
