ABSTRACT:
A basically metal frame coffee table or stacked shelves or the like employing a plurality of tubes of circular, square or other regular shape joining at intersections by an improved corner member. The improved corner member is preferably die cast in a single piece including a pair of arms which define connectors for two adjoining tubes and an orthogonal opening to receive a leg. The corner member includes an integral support for holding a shelf. The integral support conceals a fastening member employed to hold the leg in place. Each of the arms define at least one recess at a predetermined distance outward from the corner and located in intimate contact relationship with the frame tubing whereby the tubes may be assembled to the corners merely by staking the underside of the frame to deform the tube locally into the recess of the corner member and thereby produce a fixed permanent frame. The legs are secured to the frame by removable fasteners whereby the legs may be removed, stored flat and the entire table may be transported in a flat or "knocked down" condition and easily assembled with one simple tool. In one embodiment the leg tube opening in the corner member is capped to provide an ornamental top. In another embodiment the leg tube opening extends fully through the corner member to provide for continuous upright leg members and for use in stacked tables or shelves.
