Abstract:
1. An interlockable element for a structure assembly set, comprising: an at least partially planar body and at least one connector edge having associated therewith a first A-type and B-type connector pair disposed about a first axis of rotation and a second A-type and B-type connector pair disposed about a second axis of rotation; wherein for said at least one connector edge the first and second axes of rotation are disposed on opposing sides of a generally rectangular quadrilateral of a specified dimension, with each of one pair of diagonally opposite vertices of the quadrilateral situated internally to each of said A-type connectors and each of the other pair of diagonally opposite vertices of the quadrilateral situated internally to each of said B-type connectors; wherein the quadrilateral is generally disposed in a plane that is generally perpendicular to the plane of said at least partially planar body; wherein each A-type connector includes a first pair of rods that extend from the at least one connector edge, with each rod of the first pair of rods including a protrusion on the side of the rod of the first pair of rods that faces away from the other rod of the first pair of rods and each B-type connector includes a second pair of rods that extend from the at least one connector edge, with each rod of the second pair of rods including an indentation in the side of the rod of the second pair of rods that faces the other rod of the second pair of rods; and wherein said connector pairs are adapted for rotational interlocking engagement with said connector pairs of another said element.
