Abstract
A complex, load bearing structure which is formed from a series of steel links of a standard design which are joined to one another end to end. Each link has a ball portion on an end of an elongate central portion and a socket portion on the other end of the elongate central portion. The ball portion has a spherical or part-spherical outer surface and the socket portion has a part-spherical inner surface, and the ball portion and socket portion are so sized that the ball portion will fit snugly within the socket portion of a similar link for limited universal movement of the link and the similar link relative to one another. When the link and the similar link have been positioned in a proper relationship to one another, they are joined together by welding, soldering or adhesively. Preferably, each link is made integrally, in a single piece, from a steel tube which is copper plated on its exterior.
