ABSTRACT:
A device for joining tubular members of any cross section is disclosed. Typically, two parallel tubes are joined by a transverse tube. A rod is centered inside the transverse tube by a washer disposed at each end of the transverse tube. The rod may be threaded directly to one of the parallel tubes or to a reinforcing sleeve placed inside one of the parallel tubes. The other end of the rod has a small protuberance or head that is passed through an aperture in the wall of the other parallel tube. A wedge provided with a longitudinal slot, open at the thinner end of the wedge, is forced to engage with the head of the rod. The slot of the wedge is of a width slightly greater than the diameter of the rod such that the slot is easily engaged by the rod. The rod is subjected to tension stress and the transverse tube is subjected to compression stress. A rigid structure is provided having a smooth external joint, the fastening means being wholly disposed within the tubular members. The present invention has particular utility with reference to the joining of tubular bed frame members.
