Abstract
Abstract The invention is directed to a lounge of sturdy construction having special merit as a safe reliable sea lounge and is characterized by the provision of an inflatable generally flat central platform which is buoyant and substantially rigid when inflated and which is surrounded with a plurality of separate inflatable peripheral compartments rising above the platform when inflated. The invention is further characterized by the arrangement of the peripheral compartments which provide a buoyancy distribution that will impart complete stability to the lounge when in use in the water and yet will enable the lounge to be easily mounted by a person in the water. The invention is further characterized by the provision of a back and sides to support a person on the lounge in a comfortable reclining position with his weight properly oriented on the lounge.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
An inflatable lounge comprising an inflatable generally flat platform, said platform having upper and lower panels, when said platform is inflated and maintained in substantially parallel relation by a plurality of inflatable air compartments disposed in spaced relation within said platform joined to said upper and lower panels whereby the volume of air contained in said platform and said plurality of air compartments disposed therein, is maximized for greater buoyancy and rigidity, and a plurality of separate peripheral compartments completely surrounding said central platform when inflated, and means for inflating said central platform, said plurality of air components disposed within said platform and said peripheral compartments surrounding said platform.
Claim 2
Dependent Claim
109 words
An inflatable lounge comprising an inflatable generally flat platform, said platform having upper and lower panels, when said platform is inflated and maintained in substantially parallel relation by a plurality of inflatable air compartments disposed in spaced relation within said platform joined to said upper and lower panels whereby the volume of air contained in said platform and said plurality of air compartments disposed therein, is maximized for greater buoyancy and rigidity, and a plurality of separate peripheral compartments completely surrounding said central platform when inflated, and means for inflating said central platform, said plurality of air components disposed within said platform and said peripheral compartments surrounding said platform.
Claim 3
Dependent Claim
30 words
