b. Patent Claims
Short axis of diamond = 0.44
Long axis of diamond = 0.71
by virtue of which the dome comprises only two types of diamond sections and the edges of the panels are aligned along parallel lines defining a three-eighths sphere, one half sphere, and five-eighths sphere each terminating in a base plane defined by the aforesaid aligned edges of the panels.
2. A geodesic dome comprised of panels arranged in overlapping relation one to another, said panels having inner and outer sheets and spacing means between said inner and outer sheets, said panels in their assembled relationship exhibiting an overall pattern of planar triangular facets which are paired in diamond-shaped sections grouped in geodesic alignment, i.e. with edges of diamond sections lying substantially in planes containing the center of a sphere and whose intersections with said sphere define a spherical icosahedron and with other edges of the diamond sections lying substantially in planes containing the center of said sphere and whose intersections therewith define great circle arcs intersecting on one another in a three-way grid pattern, the chord factors of the edges of the triangular faces of the icosahedron and grid being as follows:
Sides adjacent said acute angles = 0.42
and the other three of said six sections of the group being alternated with the first three sections and having the following chord factors:
Short axis of diamond = 0.38
Remaining sides = 0.33
Sides adjacent said acute angles = 0.42
1. a geodesic dome comprised of panels arranged in overlapping relation to one another, said panels having inner and outer sheets and spacing means between said inner and outer sheets, said panels in their assembled relationship exhibiting an overall pattern of planar triangular facets which are paired in diamond-shaped sections, six diamond sections grouped together with the vertexes of the acute angles at one end of the long axis of each meeting at a common point, three of the six sections of the group having the following chord factors:
3. Chords adjacent the vertexes of the icosahedron = 0.220
4. Chords aligned with and intermediate the first-named chords = 0.329
5. Chords connecting the ends of chords (1) = 0.260
6. Chords having common intersections with chords (1) and (3) = 0.309
7. Chords intersecting adjoining ends of intermediate chords (2) = 0.313
8. Remaining chords = 0.325
By virtue of which the edges of the panels are aligned along parallel lines defining a three-eighths sphere, one half sphere and five-eighths sphere, one half sphere and five-eighths sphere each terminating in a base plane defined by the aforesaid aligned edges of the panels.
