ABSTRACT:
An interlockable element for a structure assembly set includes 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. The first and second axes of rotation are disposed on opposing sides of a generally rectangular quadrilateral of a specified dimension. Each of one pair of diagonally opposite vertices of the quadrilateral are situated internally to each of the A-type connectors and each of the other pair of diagonally opposite vertices of the quadrilateral are situated internally to each of the B-type connectors; and the quadrilateral is generally disposed in a plane that is generally perpendicular to the plane of the body of the interlockable element. The A-type connectors include a pair of rods having protrusions and the B-type connectors include a pair of rods having facing indentations, and the connector pairs of one element are adapted for rotational interlocking engagement with the connector pairs of another like element.
