Claims
- 1. A rectangular elevated floor plate comprising:
- (A) a top panel,
- (B) a polygonal tessellation pattern of concentric rows of ribs attached and orthogonally projecting from said panel,
- (C) a peripheral rib attached and orthogonally projecting from along the edges of said panel,
- (D) a plurality of ejector pin bosses integrally attached to one of the sides of at least some of the polygons in said tessellation pattern;
- all of said tessellation pattern ribs and bosses being of the same depth projecting orthogonally the same distance from the same side of said panel, and the thickness of said ribs in each said row inwardly from said base ribs to the center of said plate being thicker with the thickest ribs being at the center of said plate, and the thickness and depth of said peripheral ribs being different from said adjacent pattern ribs.
- 2. A floor plate according to claim 1 wherein said rectangular plate is square.
- 3. A floor plate according to claim 1 wherein said panel is uniform and solid.
- 4. A floor plate according to claim 1 wherein said panel is perforated.
- 5. A floor plate accroding to claim 4 wherein the perforations in said panel are slots.
- 6. A floor plate according to claim 5 wherein said slotted plate is thicker than a uniform solid plate.
- 7. A floor plate according to claim 1 wherein said tessellation pattern of ribs and said top panel are integral.
- 8. A floor plate according to claim 1 wherein said polygons are alternate octagons and squares.
- 9. A floor plate according to claim 8 wherein alternate sides of said octagons have ratio of lengths of one to the square-root-of-two, and said squares have sides equal to the length of said octagon sides of the square-root-of-two.
- 10. A floor plate according to claim 1 wherein the sides of said ribs and bosses all have an included angle taper away from their bases in said panel of at least about 1.degree..
- 11. A floor plate according to claim 10 wherein said taper has an included angle of about 3.degree..
- 12. A floor plate according to claim 1 wherein said thickness of said ribs in the said rows inwardly from said base ribs increase in equal steps up from about 20% to about 50% thicker at the center of said plate.
- 13. A floor plate according to claim 12 wherein the increase in thickness of said ribs is about 30%.
- 14. A floor plate according to claim 1 wherein the symmetry of said ejector pin bosses is at least 180.degree. in the plate.
- 15. A floor plate according to claim 1 including adjustable vertical supports for each corner of said plate.
