Abstract
Abstract A method of manufacturing a support structure, or leg, for a piece of furniture such as a table or the like. A blank of planar sheet material is provided with a rectangular opening adjacent one end and bent about an axis extending through the opening to form the support structure of the invention. The opening is sized such that after bending an edge of a table top is inserted in the opening and supported thereby. A plurality of the support structures, or legs, are attached to the table top to provide necessary support.

Claim 1
Independent Claim
213 words
A method of producing an article of furniture having at least one columnar support structure comprising the steps of: (a) providing a top having generally parallel upper and lower planar surfaces and a predetermined thickness; (b) providing a blank of planar sheet material having a first upper edge and a second lower edge joined by opposed side edges; (c) forming at least one rectangular opening in said blank, said opening including opposed first and second sides disposed parallel to the lower edge, and spaced apart a predetermined distance slightly greater than the thickness of said top; (d) providing an axis on said blank intersecting said opening and normal to the second lower edge, the axis dividing said blank into first and second portions; (e) bending said blank about said axis effecting relative displacement of the first and second portions and said opening therein thereby producing a support structure having a convex side and a concave side; (f) providing said upper and lower sides of said opening with elastomeric pads; and (g) assembling the columnar support structure on one edge of said top whereby the top is inserted into yieldably gripping engagement with said pads in the rectangular opening in the convex side of the support structure and supported on the second side thereof.
