Abstract
Abstract An inflatable suntanner comprising an upper transparent layer, a middle reflective layer and a bottom layer which are all made of flexible, gas impervious material. The middle layer is bonded to the upper layer at a plurality of upper joints and to the bottom layer at a plurality of lower joints, with the area or size of each upper joint being different from that of each lower joint so as to corrugate those portions of the middle reflective layer interconnecting the upper and lower joints. Accordingly, sunlight passing through the upper transparent layer and incident on the corrugated reflective layer is both evenly and irregularly reflected upon the side not exposed to the sun rays, of a user on the suntainner so as to expedite a homogeneous suntan.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
An inflatable suntanner comprising an upper transparent layer, a middle reflective layer and a bottom layer each of which is made of a flexible, gas impervious material, said middle layer being bonded to said upper layer at a plurality of upper joints to form an upper gas chamber between said upper layer and said middle layer, and bonded to said bottom layer at a plurality of lower joints to form a lower gas chamber between said middle layer and said bottom layer, characterized in that: the size of each of said upper joints is different from that of each of said lower joints so as to corrugate those portions of said middle reflective layer interconnecting said upper and lower joints, whereby sunlight passing through said upper transparent layer and incident on said corrugated reflective layer can be irregularly reflected upon the side of the user not exposed to the sun rays so as to expedite a homogeneous suntan.
Claim 2
Dependent Claim
158 words
An inflatable suntanner comprising an upper transparent layer, a middle reflective layer and a bottom layer each of which is made of a flexible, gas impervious material, said middle layer being bonded to said upper layer at a plurality of upper joints to form an upper gas chamber between said upper layer and said middle layer, and bonded to said bottom layer at a plurality of lower joints to form a lower gas chamber between said middle layer and said bottom layer, characterized in that: the size of each of said upper joints is different from that of each of said lower joints so as to corrugate those portions of said middle reflective layer interconnecting said upper and lower joints, whereby sunlight passing through said upper transparent layer and incident on said corrugated reflective layer can be irregularly reflected upon the side of the user not exposed to the sun rays so as to expedite a homogeneous suntan.
Claim 3
Dependent Claim
18 words
An inflatable suntanner as described in claim 1, wherein said lower joint is larger than said upper joint.
Claim 4
Dependent Claim
19 words
An inflatable suntanner as described in claim 1, wherein said upper gas chamber communicates with said lower gas chamber.
Claim 5
Dependent Claim
21 words
An inflatable suntanner as described in claim 1, wherein said upper gas chamber does not communicate with said lower gas chamber.
Claim 6
Dependent Claim
185 words
An inflatable suntanning support mattress for achieving a substantially even distribution of light rays across the unexposed surface of a body comprising: a first upper transparent layer, a second middle reflective layer and a third bottom layer, each of said layers being made of a flexible, gas impervious material; a plurality of upper joints bonding said first upper layer to said second middle layer to form an upper gas chamber between said upper layer and said middle layer; a plurality of lower joints bonding said third bottom layer to said second middle layer to form a lower gas chamber between siad middle layer and said bottom layer, the size of each of said upper joints being different from that of each of said lower joints so as to form a corrugated surface on the portions of said second middle layer between said upper and lower joints, said corrugated surface thereby randomly reflecting light rays incident thereon in a plurality of directions to impinge against the unexposed surface of a body for achieving a substantially even distribution of light rays across said unexposed surface of body.
