ABSTRACT:
A support stand is formed from three orthogonally oriented intersecting slat pairs, with the joints at this intersection and also spaced along the support stand being of a special interlocking construction which creates a quite rigid joint in all dimensions of possible movement without the use of any fasteners or adhesive. Although the possible manifestations of products using the basic stand construction are quite varied, the illustrated embodiments include a support rack or "tree", a table, and a lamp.
