Abstract
A supporting structure of one piece of sheet material constituting a top and several legs depending from that top in one piece has for each of these several legs an angled profile of that one piece of sheet material and in one piece with the top across the entire profile. Such supporting structure may be made of a blank of sheet material forming a pattern having a central portion for the top, first and second portions projecting from a first side of that central portion for first and second legs, third and fourth portions projecting from an opposite second side of the central portion for third and fourth legs, and first and second side panel portions projecting from opposed third and fourth sides of the central portion. These first, second, third and fourth portions are provided, respectively, with lateral ledges of which each is spaced from an adjacent one of the first and second side panel portions by a notch for a butt joint of each of the lateral ledges with an adjacent side panel portion. Angled structures may be formed for legs from the first, second, third and fourth portions of such blank with lateral ledges.
