ABSTRACT:
A table base construction includes a plurality of leg assemblies, a central attachment assembly integrating each of the leg assemblies, a vertical standard assembly mounted on the central attachment assembly, and a support plate assembly mounted on the vertical standard assembly. The leg assemblies include a plurality of elongated strips that are interconnected by machine screws in an overlayed construction.
The central attachment assembly centrally connects each of the leg at its inner end in juxtaposed radial relation. The central attachment assembly includes a column washer and an attachment washer. The legs are affixed at their inner ends to the attachment washer by attachment screws extending through the aligned bores in the leg assemblies and the column washer and engaged in threaded bores in the attachment washer. When the leg assemblies are so connected, free edges at the inner ends of the leg assemblies form a non-circular opening.
The vertical standard assembly includes a hollow column supported between the attachment washer and the support plate assembly. A tension rod is affixed to the support plate assembly and extends through the hollow column. The rod includes a portion having a non-circular outer surface that is complementary to the non-circular opening, to prevent rotation of the support plate assembly bearing a table top relative to the leg assemblies. The rod is threadedly engaged at its end with a nut that is tightened against the leg assemblies to tension the rod.
