Abstract:
An interlockable element for a structure assembly set, comprising:an at least partially planar body and a 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 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; and wherein said connector pairs are adapted for rotational interlocking engagement with said connector pairs of another said element.
