Abstract

Abstract A building of geodesic type and comprised of four sub-assembly hexagonal units, one of which units constitutes a roof and the other three are disposed in tripod fashion to support the roof and together therewith constitute a generally hemispherical space capturing structure. The upper portions of the spaces between the three wall hexagonal units are closed by isosceles preformed panels which will ordinarily be flat and trapezoid in form and identical with each other, while all the hexagonal units are also identical with each other and each composed of six identical triangular panels. The triangular panels are isosceles and apices of the six triangles in each unit are at a common point removed from the common plane of the bases of the triangles so that the units are dished. All the panels are peripherally bevelled for ease and stability of interconnection and the building is completely prefabricated. From the foregoing it will be evident that the building is constructed from elements of only two basic shapes, namely, an isosceles triangle and an isosceles trapezoid, all the triangles being also identical.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 111 words
A geodesic type building having a self-supporting shell, said shell comprising: an equilateral hexagonal roof sub-assembly unit having the peripheral edges thereof horizontal, and three hexagonal wall sub-assembly units in upstanding tripod arrangement, the lowermost edges thereof being coplanar and horizontal and together defining the base plane of the building, and the upper edges thereof being secured to alternate edges of said roof sub-assembly unit; and three trapezoidal panels each having one edge secured to an edge of said roof sub-assembly unit between two of said wall subassemblies and having two opposing edges secured to adjacent edges of said two wall sub-assembly units; all of said units being of identical planform.
Claim 2
Dependent Claim 111 words
A geodesic type building having a self-supporting shell, said shell comprising: an equilateral hexagonal roof sub-assembly unit having the peripheral edges thereof horizontal, and three hexagonal wall sub-assembly units in upstanding tripod arrangement, the lowermost edges thereof being coplanar and horizontal and together defining the base plane of the building, and the upper edges thereof being secured to alternate edges of said roof sub-assembly unit; and three trapezoidal panels each having one edge secured to an edge of said roof sub-assembly unit between two of said wall subassemblies and having two opposing edges secured to adjacent edges of said two wall sub-assembly units; all of said units being of identical planform.
Claim 3
Dependent Claim 11 words
A building according to claim 1 wherein said units are identical.
Claim 4
Dependent Claim 17 words
A building according to claim 1 wherein each of said units consists of six identical triangular panels.
Claim 5
Dependent Claim 50 words
A building according to claim 3 wherein each unit is dished, the outside edges of each unit being in a common plane and the apices of the triangular of each unit being of a common point removed from said plane, the totality of said points lying in a projected hemisphere.
Claim 6
Dependent Claim 20 words
A building according to claim 3 wherein each triangular panel is isosceles with the base slightly shorter than the sides.
Claim 7
Dependent Claim 45 words
A building according to claim 1 wherein the trapezoid panels are identical isosceles trapezoids with the longest sides disposed downwardly as a header for a wall opening of a width dimension greater than the length dimension of the base of one of said triangular panels.
Claim 8
Dependent Claim 59 words
A building according to claim 1 wherein each of said units consists of six identical isosceles triangular panels with the apices thereof at a common point and the bases of the triangles constituting said edges of said units, and the perpendiculars of said triangular panels subtending angles of 30* at the center of said base plane of the building.
