Abstract
Abstract A building construction in which a basic unit of twelve elements is fabricated into a rectangular paraellelepiped to define a structurally rigid module requiring no additional structural members. A plurality of modules in the form of rectangular parellelepipeds can be assembled together in side-by-side and/or stacked relationship to form a building of substantially any desired size. Each of the twelve elements of each module has at least two legs joining the legs of adjacent elements at right angles to form a closed parallelepiped.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
210 words
In a building construction, at least two abutting modules; each module comprising a six sided structurally rigid unit consisting of 12 elements, each of said elements having a first leg and a second leg joined to said first let at an angle of 90* with respect thereto, each leg having two opposite ends and a free edge, said elements being joined at the ends thereof to form a rectangular parallelepiped having eight joints formed of three of said elements, the leg ends at each joint being oriented to define a joint comprised of three intersecting edges with each edge extending from the point of intersection in a direction away from the interior of said parallelepiped and with the free edges of the four legs on each side of each module extending in an outward direction away from the interior of said parallepiped, the free edges on the four outwardly directed legs on each side of each module being in coplanar relation, said free edges on one side of one module being in abutting, edge-to edge relation with the free edges on a side of the second module, whereby the respective opposed and outwardly directed legs on the abutting sides of the two modules are in coplanar relation with each other.
Claim 2
Dependent Claim
210 words
In a building construction, at least two abutting modules; each module comprising a six sided structurally rigid unit consisting of 12 elements, each of said elements having a first leg and a second leg joined to said first let at an angle of 90* with respect thereto, each leg having two opposite ends and a free edge, said elements being joined at the ends thereof to form a rectangular parallelepiped having eight joints formed of three of said elements, the leg ends at each joint being oriented to define a joint comprised of three intersecting edges with each edge extending from the point of intersection in a direction away from the interior of said parallelepiped and with the free edges of the four legs on each side of each module extending in an outward direction away from the interior of said parallepiped, the free edges on the four outwardly directed legs on each side of each module being in coplanar relation, said free edges on one side of one module being in abutting, edge-to edge relation with the free edges on a side of the second module, whereby the respective opposed and outwardly directed legs on the abutting sides of the two modules are in coplanar relation with each other.
Claim 3
Dependent Claim
210 words
In a building construction, at least two abutting modules; each module comprising a six sided structurally rigid unit consisting of 12 elements, each of said elements having a first leg and a second leg joined to said first let at an angle of 90* with respect thereto, each leg having two opposite ends and a free edge, said elements being joined at the ends thereof to form a rectangular parallelepiped having eight joints formed of three of said elements, the leg ends at each joint being oriented to define a joint comprised of three intersecting edges with each edge extending from the point of intersection in a direction away from the interior of said parallelepiped and with the free edges of the four legs on each side of each module extending in an outward direction away from the interior of said parallepiped, the free edges on the four outwardly directed legs on each side of each module being in coplanar relation, said free edges on one side of one module being in abutting, edge-to edge relation with the free edges on a side of the second module, whereby the respective opposed and outwardly directed legs on the abutting sides of the two modules are in coplanar relation with each other.
Claim 4
