Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
93 words
A multi-purpose, multi-position support structure comprising an essential planar rigid support member, first and second planar base assemblies rigid with said main support member, said first and second base assemblies being disposed at first and second different angles with respect to said main support member and adapted to provide stable support for said main support at different angles with respect to a supporting surface, said second angle being larger than said first angle and being not greater than 45° and the sum of said first and second angles being not greater than 80°.
Claim 2
Dependent Claim
93 words
A multi-purpose, multi-position support structure comprising an essential planar rigid support member, first and second planar base assemblies rigid with said main support member, said first and second base assemblies being disposed at first and second different angles with respect to said main support member and adapted to provide stable support for said main support at different angles with respect to a supporting surface, said second angle being larger than said first angle and being not greater than 45° and the sum of said first and second angles being not greater than 80°.
Claim 3
Dependent Claim
37 words
This structure according to claim 1 wherein the tangent of said first angle is greater than 1/2 of the sine of double the second angle divided by the quantity (2 - cosine of double said second angle).
Claim 4
Dependent Claim
41 words
The structure according to claim 1 wherein one of said base assemblies forms with the adjacent portion of said support member a storage compartment and the other base assembly is interrupted intermediate its ends to provide access to said storage compartment.
