Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
In a set of building units, a plurality of interfitting units, each of said units comprising a first U-shaped member having first and second legs and a base all in a first common plane, a second U-shaped member having the same dimensions as the first U-shaped member and having first and second legs and a base in a second common plane parallel to and spaced from said first common plane, a connecting element extending in a direction transverse to said common planes and between the free ends of the first leg of said first U-shaped member and the second leg of said second Ushaped member, the longitudinal axis of said base of said first U-shaped member extending transversely to the longitudinal axis of the base of said second U-shaped member in said respective parallel common planes, and the base of said first U-shaped member and the first leg of said second U-shaped member lying in a plane transverse to said parallel common planes.
Claim 2
Dependent Claim
163 words
In a set of building units, a plurality of interfitting units, each of said units comprising a first U-shaped member having first and second legs and a base all in a first common plane, a second U-shaped member having the same dimensions as the first U-shaped member and having first and second legs and a base in a second common plane parallel to and spaced from said first common plane, a connecting element extending in a direction transverse to said common planes and between the free ends of the first leg of said first U-shaped member and the second leg of said second Ushaped member, the longitudinal axis of said base of said first U-shaped member extending transversely to the longitudinal axis of the base of said second U-shaped member in said respective parallel common planes, and the base of said first U-shaped member and the first leg of said second U-shaped member lying in a plane transverse to said parallel common planes.
Claim 3
Dependent Claim
46 words
A set of building units as in claim 1 wherein the legs of each U-shaped member are spaced from each other a distance equal to the cross-sectional dimension of said legs whereby the U-shaped portion of one unit is positionable between the legs of another unit.
Claim 4
Dependent Claim
23 words
A set of building units as in claim 1 wherein the legs of said first and second U-shaped members are square in cross-section.
Claim 5
Dependent Claim
29 words
A set of building units as in claim 3 wherein the connecting element of each unit is square in cross-section and equal to the cross-sectional dimension of said legs.
Claim 6
Dependent Claim
21 words
A set of building units as in claim 1 wherein the exterior dimensions of each of said units form a cube.
