<p>PURPOSE:To provide a mounting press fitting for wall plate that can increase the strength of the metal mold of a part on which a folded piece is stamped out and worked to improve durability. CONSTITUTION:A thin metal plate is stamped out and worked to form the main body 3a of a mounting fitting 3 for wall plate into a square frame shape. A pair of protruded pieces 7a, 9a are protruded in an integrated manner to the inside from the inner ends of side frame parts 6a, 6b forming the main body 3a. V-shape protruded pieces 7b, 9b are extended from the protruded pieces 7a, 9a so that they are opposed to one another along the side frame parts 6a, 6b, and the folded pieces 7, 9 are formed into nearly triangular frames by means of the protruded pieces 7b, 9b. The folded pieces 7, 9, when lifted, are deformed in a pantograph way. In this structure, the size and the area of a triangular vacancy A surrounded by the protruded pieces 7b, 9b extended in nearly V-shape can be increased compared with a conventional case.</p> |
