  • Patent number: 5150136
    Abstract: Disclosed herein is a structure adapted to connect eye-glass parts to each other and comprising a small plate integrally extending from a main body of one eyeglass part which is made of a hardly solderable metal such as pure titanium or Ni-Ti base alloy. A connecting member made of an easily solderable metal has side walls and a cross section of U-shape defining a channel for receiving the small plate which has such constricted regions as formed at both sides surfaces of the small plate. The side walls of the connecting member are folded onto the inserted small plate such that inner surface material of said member are pressed into the constricted regions so as to be secured to said small plate. To the connecting member unseparably wound around the small plate, any other eyeglass part can be soldered or welded.
