Patent ID: 7954296

Claim:
A joint for connecting node sets of tetrahedral structures comprising: a pair of nodes, each said node having first, second, and third faces which oppose fourth, fifth and sixth faces respectively, one of the nodes is a left handed node and the other is a right handed node; at least first, second, and third holes on the corresponding first, second, and third faces of each of the nodes extend therethrough creating first, second and third pathways to the opposing fourth, fifth, and sixth faces; wherein the axes of the pathways of said left handed node correspond to a left handed ruling line of a hyperboloid of revolution of one sheet whose curvature is such that the longitudinal axes of said pathways are mutually orthogonal and such that said first, second, and third pathways are aligned in first, second, and third directions so to not intersect; wherein the axes of the pathways of said right handed node correspond to a right handed ruling line of a hyperboloid of revolution of one sheet whose curvature is such that the longitudinal axes of said pathways are mutually orthogonal and such that said first, second, and third pathways are aligned in first, second, and third directions so to not intersect; and wherein said first hole on said first face of said left handed node and said first hole on said first face of said right handed node are directly aligned with one another and said first surfaces adjoin creating a matching line of interface between said surfaces.
