Patent ID: 7662014

Claim:
A joint system for a composite construct composed of at least two polyhedric cells, said joint system securing said two polyhedric cells together, said two polyhedric cells having a plurality of facets and sharing a common facet, said joint system comprising: a key element having a key axis and a key plane, said key axis extending generally perpendicular to said key plane, first, second, and third key joining axes extending generally within said key plane, said key joining axes being arrayed generally radially of said key axis and generally equally angularly spaced from one another around said key axis; a common polyhedra joint element having a common plane generally congruent with said common facet, said common plane extending generally perpendicular to said key plane and including a common joining axis extending generally within said common plane; a first polyhedra joint element having a first polyhedra plane generally congruent with a first facet of a first of said two polyhedric cells, said first polyhedra plane extending generally perpendicular to said key plane and including a first joining axis extending generally within said first polyhedra plane; and a second polyhedra joint element having a second polyhedra plane generally congruent with a second facet of a second of said two polyhedric cells, said second polyhedra plane extending generally perpendicular to said key plane and including a second joining axis extending generally within said second polyhedra plane, said first, second, and third key axis extending generally congruently with said common, first, and second joining axis, respectively.
