Abstract
Abstract A building having a roof constructed of a plurality of initially flat, side by side, hinged together roof sections. Beneath the roof are two opposing end walls each constructed of a like plurality of wall panels that are hinged together. Each wall panel is further hinged to a corresponding roof section. The hinge lines are arranged so that every set of two roof sections and corresponding two wall panels has hinge lines that originate from a common point. The angle between the hinge axes connecting corresponding sets of roof sections and wall panels is other than 180* and such that the sum of the angles between the hinge axes of a given set of two wall panels equals the sum of the angles between the hinge axes of a corresponding set of two roof sections. When lifting the roof the panels pivot downwardly with respect to the roof sections into relative angular inclination with each other. Simultaneously there with the roof sections are pivoted out of their common plane into relative angular positions. The relative angularity is a function of the relative positioning of the hinge axes and can be varied as desired to construct buildings having a wide variety of shapes and sizes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
156 words
A method for constructing side and roof portions of a building comprising the steps: providing a pair of coplanar first and second panels; providing a pair of coplanar third and fourth panels above said first and second panels; pivotally connecting all four panels on four axes, each axis intersecting the other three axes at a common point of intersection, one axis connecting the first and second panels, a second axis connecting said third and fourth panels, a third axis connecting said first and third panels, and fourth axis connecting said second and fourth panels, the sun of the angles between the axes of pivotal intersection Being substantially less than 360*; and lifting said third and fourth panels, causing said first and second panels to pivot upwardly relative to said one axis and said third and fourth panels to pivot downwardly relative to the second axis; whereby said panels become rigidly inclined with respect to connecting panels.
Claim 2
Independent Claim
156 words
A method for constructing side and roof portions of a building comprising the steps: providing a pair of coplanar first and second panels; providing a pair of coplanar third and fourth panels above said first and second panels; pivotally connecting all four panels on four axes, each axis intersecting the other three axes at a common point of intersection, one axis connecting the first and second panels, a second axis connecting said third and fourth panels, a third axis connecting said first and third panels, and fourth axis connecting said second and fourth panels, the sun of the angles between the axes of pivotal intersection Being substantially less than 360*; and lifting said third and fourth panels, causing said first and second panels to pivot upwardly relative to said one axis and said third and fourth panels to pivot downwardly relative to the second axis; whereby said panels become rigidly inclined with respect to connecting panels.
Claim 3
Dependent Claim
24 words
The method of claim 1, the angles of intersection between said second axis and said third and fourth axes being substantially equal and acute.
Claim 4
Dependent Claim
36 words
The method of claim 1, said first and second panels having parallel side edges that extend perpendicular to intersecting base edges, said first and second panels forming a stable support for said third and fourth panels.
Claim 5
Dependent Claim
92 words
The method of claim 1 and further comprising the steps: providing a fifth panel coplanar with said first and second panels; providing a sixth panel coplanar with said third and fourth panels; and, pivotally connecting said fifth and sixth panels on a fifth axis that intersects said third axis, pivotally connecting said fifth panel with said first panel on a sixth axis, pivotally connecting said sixth panel with said third panel on a seventh axis, said sixth and seventh axes intersecting said fifth and third axes at a common point of intersection.
Claim 6
Independent Claim
159 words
A method for constructing a roofed building comprising the steps of hingeably connecting a number of flat end panels to construct two opposing end walls for the building, each end wall having a pair of panels; placing a pair of flat roof sections over the panels; hingeably connecting the roof sections to construct a roof for the building, hingeably connecting an end wall to each end of the roof with the hinge axes between any pair of corresponding panels and sections intersecting at a common point, the sum of the angles between hinge axes which meet at a common point being substantially less than 360*; and thereafter erecting the building by lifting the roof sections, allowing the wall panels to pivot gravitationally downwardly with respect to the sections and causing the sections and panels to become rigidly inclined with respect to its pair; then supporting the panels on the ground to form a stable support for the roof sections.
