ABSTRACT:
A modular element is disclosed which includes a plurality of rib pairs protruding from a surface of a base. Each rib pair includes first and second ribs which extend longitudinally parallel to each other and which are transversely spaced to define therebetween a first groove. Similarly, the rib pairs also longitudinally extend parallel to each other with adjacent rib pairs defining therebetween a second groove. Various relationships among the transverse widths of the first and second ribs, the rib pairs, and the first and second grooves are disclosed to permit mating modular elements to have a plurality of orientations with respect to each other in face-to-face contact. Likewise, relationships among the transverse height of the base, and the transverse height of the modular element, and the transverse widths of the first and second ribs, rib pairs, and first and second grooves are also disclosed to permit mating modular elements to have a plurality of orientations in end-to-face contact. Intermediate and interconnecting elements for such matable modular elements are also disclosed, as are a plurality of rib designs providing for either a disconnectable fit, a semi-permanent locking fit, or a permanent locking fit of mating modular elements.
