Definitions

  • the present invention relates to a structure of an improved chair, particularly to a structure of an improved chair by bending inward the asymmetric edge of the metal-plate to form a fit-rim and then fit the fit-rim into the U-shape fixing slit of the edge-bar having an extended part.
  • a metal-net frame 51 is formed by processing a metal material using a stamping die on a press. And the metal-net frame 51 is welded on the chair 5 using the high-frequency oscillation energy of ultrasonic, as shown in Fig. 7(B).
  • the metal-net frame 51 is fixed on the chair 5 by bending inward the asymmetric edge 52 of the metal-net 51 and then fixing asymmetric edge 52 on the chair 5 by welding on the inside of the chair 5 frame with welding material 53, as shown in Fig. 8(B).
  • the objective of the present invention is to provide a structure of an improved chair, which provides a U-type fixing slit between the extended part of the edge-bar and the principal part which can facilitate fast fitting the metal-plate and welding the metal-plate on the chair-seat firmly with 3-5 welding spots along each side.
  • the another objective of the present invention is to provide a structure of an improved chair which can reduce the usage of the welding material and can reduce the time and cost of welding.
  • the still another objective of the present invention is to provide an operating environment which the environmental pollution can be reduced, the environmental cleanness can be increased, and the temperature can be lower.
  • the still another of the present invention is to provide a structure of an improved chair which the working hour for grinding, milling, and polishing and the grinding media can be reduced.
  • the still another objective of the present invention is to enhance the beauty of the chair and to provide a safe chair that can hide the asymmetric edge after the metal-net frame is cut, wherein by welding the extended part, fit-rim and the principal part together via the holes of the edge-bar, and welding with several welding spots to join the extended part, fit-rim and the principal part together, and then fast polishing the welding material on the holes.
  • the structure of an improved chair can achieve the above-mentioned objectives of the present invention, comprising:
  • a chair the chair composed of tube or prism as the principal holder has front-legs, rear-legs, arm-rests and an extended-bar. There is a fix spot on each front-leg. The fix spot is used to fix the set of the edge-bar of the chair-seat or the extended-bar.
  • a set of edge-bars of chair-back is composed of one upper edge-bar, one lower edge-bar and two side edge-bars by fixing both ends of the upper and lower edge-bars on the rear-legs of the chair.
  • a set of edge-bars of the chair-seat is composed of one front edge-bar, one rear edge-bar and two side edge-bars by fixing the two side edge-bars on the fix spot of the front-leg or by placing two side edge-bars on the extended-bar of the front-legs and fixing the side edge-bars on the front-leg and fixing both ends of the rear edge-bar on the rear-leg.
  • Two metal-plates is die-cast, there are several fit-rims on the metal-plate, the fit-rim matches the frame formed by the edge-bars surround the four sides of the metal-plate and bends inward and is used for fitting into the U-shape fixing slit of each edge-bar.
  • the edge-bar having a principal part and an extended part is die-cast, there is a U-shape fixing slit between the extended part and the principal part, and the extended part has several holes. After the fit-rim of the metal-plate fitted into the U-shape fixing slit, the edge-bars and the metal-plate can be welded or riveted at the several holes of the extended part into a unified connector, which is unable to be dismantled.
  • the structure of an improved chair according to the present invention provides primarily comprising:
  • a chair1 the chair1 composed of tube or prism as the principal holder has front-legs 11, rear-legs 12, arm-rests 13 and an extended-bar 14. There is a fix spot 11 on each front-leg 11.
  • the fix spot 111 is used to fix the set of the edge-bar2 of the chair-seat or the extended-bar 14.
  • a set of edge-bars2 of chair-back is composed of one upper edge-bar2, one lower edge-bar2 and two side edge-bars2 by fixing both ends of the upper and lower edge-bars2 on the rear-legs 12 of the chair.
  • a set of edge-bars2 of the chair-seat is composed of one front edge-bar2, one rear edge-bar2 and two side edge-bars2 by fixing the two side edge-bars2 on the fix spot 11 of the front-leg or by placing two side edge-bars2 on the extended-bar 14 of the front-legs 11 and fixing the side edge-bars2 on the front-leg 11 and fixing both ends of the rear edge-bar2 on the rear-leg 12.
