Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
305 words
A device for cooling the human body in seated or reclining position comprising a water impervious, flexible base sheet of generally rectangular dimensional configuration and of sufficient length and width to contain the human body thereon; a head portion of said sheet containing pillow means for cushioning the head of the body, said pillow means comprising a flexible, water-impervious material overlying the head portion of said sheet and attached by its side edges thereto to form a compartment, and cushioning means in said compartment for supporting the head of a human body; flexible conduit means attached to and extending along edge portions of said base sheet for directing a plurality of streams of water across the surface of said sheet to form a layer of water on the sheet surface for cooling a human body residing on the sheet, said conduit means comprising a flexible water impervious strip of material sealingly attached at its side edges to edge portions of the base sheet and forming with said base sheet edge portions tubular means for directing water about a major portion of the periphery of the base sheet, and a plurality of openings in said water impervious flexible strip of material facing inwardly of edge portions of the base sheet to direct water in said plurality of streams across the surface of said sheet, said flexible conduit means further including flexible tubular means extending transversely across said base sheet along the lower edge portion of said pillow means and having a plurality of openings therein for directing streams of water across the surface of the base sheet; means for introducing water into said flexible conduit means to supply water through said plurality for openings therein; and one or more openings through the base sheet to permit discharge of excess water from the surface of the sheet.
Claim 2
Independent Claim
305 words
A device for cooling the human body in seated or reclining position comprising a water impervious, flexible base sheet of generally rectangular dimensional configuration and of sufficient length and width to contain the human body thereon; a head portion of said sheet containing pillow means for cushioning the head of the body, said pillow means comprising a flexible, water-impervious material overlying the head portion of said sheet and attached by its side edges thereto to form a compartment, and cushioning means in said compartment for supporting the head of a human body; flexible conduit means attached to and extending along edge portions of said base sheet for directing a plurality of streams of water across the surface of said sheet to form a layer of water on the sheet surface for cooling a human body residing on the sheet, said conduit means comprising a flexible water impervious strip of material sealingly attached at its side edges to edge portions of the base sheet and forming with said base sheet edge portions tubular means for directing water about a major portion of the periphery of the base sheet, and a plurality of openings in said water impervious flexible strip of material facing inwardly of edge portions of the base sheet to direct water in said plurality of streams across the surface of said sheet, said flexible conduit means further including flexible tubular means extending transversely across said base sheet along the lower edge portion of said pillow means and having a plurality of openings therein for directing streams of water across the surface of the base sheet; means for introducing water into said flexible conduit means to supply water through said plurality for openings therein; and one or more openings through the base sheet to permit discharge of excess water from the surface of the sheet.
Claim 3
