Abstract
Abstract A reflective device is disclosed which forms an enclosure, the self supporting walls of the device being provided with a highly reflective surface which will reflect and spread light rays, particularly those of the ultraviolet spectrum. The enclosure is made of a plurality of panels that are hingedly and flexibly interconnected in such a way that in the preferred embodiment the device assumes the form of an inverted frustum. Panels adjust semi-automatically to a multiplicity of different angles, providing optimum reflection on a person or persons within the enclosure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A device for reflecting light rays comprising a plurality of walls, each having a flat reflective surface and a configuration including at least a base edge, the majority of said walls being flexibly interconnected by a hinge fastener located adjacent the base edge and a flexible member spaced therefrom to assume the shape of an inverted frustum, said hinge allowing substantial angular movement whereby the wall surfaces assume different angles of repose as they are moved closer to or further from the center of the frustum.
Claim 2
Independent Claim
86 words
A device for reflecting light rays comprising a plurality of walls, each having a flat reflective surface and a configuration including at least a base edge, the majority of said walls being flexibly interconnected by a hinge fastener located adjacent the base edge and a flexible member spaced therefrom to assume the shape of an inverted frustum, said hinge allowing substantial angular movement whereby the wall surfaces assume different angles of repose as they are moved closer to or further from the center of the frustum.
Claim 3
Dependent Claim
23 words
A device as in claim 1 wherein each wall defines a base edge extending between two side edges to form a quadrilateral shape.
Claim 4
Dependent Claim
20 words
A device as in claim 1 wherein the walls are trapezoidal shape with the shortest side forming the base edge.
Claim 5
Dependent Claim
28 words
A device as in claim 1 wherein the hinge fastener comprises a hinge that has a major pivotal axis that allows freedom of movement perpendicular to the axis.
Claim 6
Dependent Claim
24 words
A device as in claim 1 wherein the flexible interconnecting means at the junction of one pair of adjacent walls comprises slip joint hinges.
Claim 7
Dependent Claim
13 words
A device as in claim 1 wherein said walls comprise an even number.
Claim 8
Dependent Claim
19 words
A device as in claim 1 wherein each of said walls comprise aluminum foil bonded to relatively stiff board.
Claim 9
Dependent Claim
22 words
A device as in claim 4 or 5 wherein the interconnecting means provides a space between adjacent side edges of the walls.
Claim 10
Dependent Claim
38 words
A device as in claim 4 wherein said hinge fastener has plates that are placed on one face of adjacent walls and on the opposite face at the next wall junction whereby an accordion folding system is provided.
Claim 11
Independent Claim
108 words
A device for reflecting and directing light rays for aesthetic and medical purposes comprising a plurality of flat, reflective, trapezoidal shaped panels, flexibly interconnected to form an enclosure in the shape of an inverted frustum, means connecting the majority of lower portion of said panels by a fastener means, said fastener means allowing substantial angular movement of said panels but resistant to compression or spreading of panel spacing at this point, means connecting the upper portion of the majority of said panels, said means being flexible couplings that allow movement of the panels in all planes and change of panel spacing at the upper portion within pre-determined limits.
Claim 12
Independent Claim
