Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
An inner tube-type recreation vehicle for supporting a person thereon, comprising: an inflatable torus-shaped tube having a central opening therethrough; a disc-shaped seat constructed of semi-rigid material for positioning in and substantially enclosing the central aperture for support of at least a portion of the person thereon; said seat having a periphery of sufficient diameter to prevent the supported person from projecting one or more of his limbs through the central opening and a plurality of angularly spaced holes formed therethrough adjacent the periphery; and a plurality of strap assemblies having straps adapted to be looped about spaced sections of the tube, and each strap having ends with complementary hook means affixed to the strap ends and adapted to oppositely extend about a section of the seat periphery and into a respective seat hole with the hook means meshing with each other to enclose the section of the seat periphery and secure the seat to the inner tube at the desired elevation.
Claim 2
Dependent Claim
162 words
An inner tube-type recreation vehicle for supporting a person thereon, comprising: an inflatable torus-shaped tube having a central opening therethrough; a disc-shaped seat constructed of semi-rigid material for positioning in and substantially enclosing the central aperture for support of at least a portion of the person thereon; said seat having a periphery of sufficient diameter to prevent the supported person from projecting one or more of his limbs through the central opening and a plurality of angularly spaced holes formed therethrough adjacent the periphery; and a plurality of strap assemblies having straps adapted to be looped about spaced sections of the tube, and each strap having ends with complementary hook means affixed to the strap ends and adapted to oppositely extend about a section of the seat periphery and into a respective seat hole with the hook means meshing with each other to enclose the section of the seat periphery and secure the seat to the inner tube at the desired elevation.
Claim 3
Dependent Claim
32 words
The recreation vehicle as defined in claim 1 wherein each of the hook means includes at least one hook finger that extends through the seat hole and about the seat periphery section.
Claim 4
Dependent Claim
51 words
The recreation vehicle as defined in claim 1 wherein at least one of the hook means has at least two hook fingers that are spaced apart a distance sufficient to receive a hook finger of the other hook means therebetween to form an interlock to enclose the seat periphery section therein.
Claim 5
Dependent Claim
