Abstract
Abstract The invention provides a molded plastic furniture article joint component, e.g. of ABS, shaped as a tee with e.g. with a 90 degree angle between the arms thereof, wherein the bores of the two arms and single leg are mutually open to one another at the common juncture of the arms and leg, wherein the outer end portions of the arms are serrated and wherein the outer end portion of the leg is provided with a plurality of longitudinal serrations so sized and tapered that there is no need for a separate operation to form a trough between the smooth and serrated portions of the leg. Usually, the plastic joint component is plated to exteriorly appear as bright metal, such as nickel-chrome, chrome or brass. The components are used with like ones to assemble e.g. tables, etageres, and the like.

Claim 1
Independent Claim
322 words
A molded joint component for tubular frame furniture such as for joining two tubular metal stretchers which approach one another at an angle in a horizontal plane with a tubular metal leg, said joint component comprising: an integral tubular molding of acrylonitrile-butadiene-styrene plastic material bearing an exterior bright metallic plating throughout and having the shape of a folded tee wherein two arms of the tee join one another in a horizontal plane and a leg depends from their juncture, the bores of the arms and leg intersecting and intercommunicating at said juncture; each arm and said leg having a smooth portion at said juncture and leading toward the three respective free ends; each arm and said leg having a serrated portion axially outwardly of the smooth portion thereof, near the three respective free ends; means defining an axially outwardly facing, circumferentially extending radial shoulder on each arm and said leg bordering the axially outer extent of the three respective smooth portions; the serrations and shoulders being disposed to permit the respective arms and leg to be forced into the bores of tubular frame elements to be joined to the extent where the elements abut the respective sholders and are interiorly gripped by the respective serrations; the serrations on said leg being constituted by a plurality of angularly spaced, longitudinally extending flutes which collectively extend from the free end of the leg to the shoulder and gradually increase in outer diameter from the free end to the shoulder; the collective outer diameter of the flutes at the shoulder on said leg being smaller than the outer diameter of said shoulder and the arms meeting one another at a right angle and the integral tubular molding further including a horizontal flange extending between the arms at their juncture, whereby a shelf may be supported upon incorporation of the joint component with like others and tubular metal stretchers and legs to constitute tubular frame furniture.
