Abstract
Abstract A buoyant structure adapted to be supported on a solid supporting surface and to float on water with an occupant therein has an elongate buoyant upper portion with a generally horizontal concave upper surface adapted to support an occupant thereon with the buoyant structure being proportioned for stability while supporting the occupant. Support portions in the form of legs depend from the upper portion for engaging the solid surface for supporting the upper portion and the occupant thereon in a position above the solid surface. A back portion extends upwardly and rearwardly from a rearward end of the upper portion and arm portions extend upwardly from opposite sides of the upper portion adjacent the rearward end thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
A buoyant structure adapted for support on a solid surface as a lounge chair, and to float on water with an occupant therein as a boat comprising: a. an elongate deck portion having a forward end and a recessed concave upper surface extending from adjacent said forward end and longitudinally of said deck portion said concave upper surface providing leg- and seat-supporting portions, for a person; b. a back portion inclined rearwardly and upwardly from the deck portion, said back portion having a recessed concave upper and forward surface merging at its lower end with the concave upper surface of the back portion providing back support for a person therein; c. a support leg depending from the deck portion and generally tapering downwardly therefrom; d. spaced support legs depending from the seat portion of the deck portion and generally tapering downwardly therefrom; e. said deck portion, back portion and support legs all being of substantially rigid buoyant material wherein the support legs contribute to the buoyancy and the center of buoyancy is substantially under the seat-supporting portion.
Claim 2
Dependent Claim
177 words
A buoyant structure adapted for support on a solid surface as a lounge chair, and to float on water with an occupant therein as a boat comprising: a. an elongate deck portion having a forward end and a recessed concave upper surface extending from adjacent said forward end and longitudinally of said deck portion said concave upper surface providing leg- and seat-supporting portions, for a person; b. a back portion inclined rearwardly and upwardly from the deck portion, said back portion having a recessed concave upper and forward surface merging at its lower end with the concave upper surface of the back portion providing back support for a person therein; c. a support leg depending from the deck portion and generally tapering downwardly therefrom; d. spaced support legs depending from the seat portion of the deck portion and generally tapering downwardly therefrom; e. said deck portion, back portion and support legs all being of substantially rigid buoyant material wherein the support legs contribute to the buoyancy and the center of buoyancy is substantially under the seat-supporting portion.
Claim 3
Dependent Claim
30 words
A buoyant structure as set forth in claim 1 wherein: a. the deck portion, back portion and supporting legs are all an integral monolithic structure of lightweight synthetic resin foam;
Claim 4
Dependent Claim
45 words
A buoyant structure as set forth in claim 1 wherein: a. arm portions are on and extend upwardly from the deck portion at sides of concave the seat-supporting surface said arm portion extending forwardly of the back portion at sides of the concave surface thereof;
Claim 5
Dependent Claim
59 words
A buoyant structure as set forth in claim 3 wherein: a. said concave supporting surface of the deck portion and the back portion and inner surfaces of the arm portions all merge in smooth transition curves; b. the deck, back and arm portions and the supporting legs are all an integral monolithic structure of rigid lightweight synthetic resin foam.
