Claim 1
Independent Claim
62 words
A substantially rectangular panel hinged across diagonally opposite corners, and including as a part thereof elevating supports extending downwardly from said opposite corners and the remaining corners on said panel, said panel being divided into triangular panels along a hinge line, and said elevating supports at said opposite corners being attached to only one of said triangular panels adjacent said hinge line.
Claim 2
Dependent Claim
62 words
A substantially rectangular panel hinged across diagonally opposite corners, and including as a part thereof elevating supports extending downwardly from said opposite corners and the remaining corners on said panel, said panel being divided into triangular panels along a hinge line, and said elevating supports at said opposite corners being attached to only one of said triangular panels adjacent said hinge line.
Claim 3
Dependent Claim
17 words
