The three-legged support is for placing on a base surface and has two legs (1,2) joined to an upper beam (4) and a third leg (3) comprising a V-shaped part, whose upper ends are joined either with the ends of the upper beam or with the upper ends of the outer two legs. The lower angle of the V-shaped part supports against the base surface at a distance from the connecting line between the two other leg support points. |
