ABSTRACT:
An article combined with other parts which assemble into an item of furniture, the article constituting a spacer of extruded aluminum having a cylindrical bore therethrough and, as seen in cross-section, grooves outboard of such bore which are right angles to each other. Bores of aligned spacers receive posts and outboard legs therein define grooves which receive vertical panels with horizontal members between spacers, such horizontal members having openings which are aligned with the bores to receive vertical pipe. The vertical pipe thereby aligns the spacers, horizontal members and indirectly the vertical members. In one embodiment, L-shaped portions formed in the extruded spaces opposite the legs define further grooves which permit the use of connecting clips between adjacent shelves. Additional spacers having further grooves to provide midway and central aligned supports for larger shelves are also disclosed.
