Abstract: A joint for use in forming a three-dimensional framed spatial structure for interior use and construction comprising three identical shaped surfaces or wings resembling the corner of a cube, each of the three identical shaped surfaces (4, 5 & 6) comprised of two different segments: the first an L-shaped segment with one hole at the intersection (23) and two holes on each arm of the "L" (26 & 27); the second segment comprising a sector of a circle whose arc measures ninety degrees (4) with a hole in the center (32) to permit attachments. These two different segments are connected on the inside surface (surface A) by a forty-five degree angle and on the outside (surface B) by a ninety-degree angle. Multiple connections and attachments can be made through the four predetermined holes (23, 26, 27, 32) located on each of the three identical shaped surfaces (4, 5, 6).
