Patent number: 5601034Abstract: A rolling stock fitting structure has laminated panels, each formed by sandwiching a core member between a pair of face plates, and channel members are placed between the face plates around the periphery of the panels and possibly in the interior thereof to provide structural strength. The laminated panels, which may be shaped to conform to a particular design, are joined and welded together to form a rolling stock body. The channels are provided with holding members for holding equipment, so that the load of the equipment on the holding member can be distributed through the channel member to the laminated panel, thereby securing the equipment reliably.Type: GrantFiled: September 20, 1994Date of Patent: February 11, 1997Assignee: Hitachi, Ltd.Inventors: Takashi Tao, Yasuo Ishimaru, Morishige Hattori, Keiji Ohmura, Hideshi Ohba

Patent number: 5188039Abstract: This invention relates to a method of fixing an inside panel of a car, and its fixing structure. In a structure for fixing an inside panel by employing an interior decoration material to form a passenger room of a car, the present invention relates to a method and a structure for fixing an inside panel of a car, particularly suitable for a railway car. An inside frame which is press-formed is fixed to frames of a car, and an inside panel is fixed to the inside frame through fasteners. Since the inside panel is fixed to the press-formed inside frame, surface uneveness does not occur on the inside panel even if any unevenness exists on the frames of the car. A cushion material is attached to the inside frame at the joint portion of two inside panels along the joint portion. The inside panel has a decoration sheet bonded to its surface, and this decoration sheet is bent back at the edge portions of the inside panel. Therefore, the appearance of the joint portion can be improved.Type: GrantFiled: August 29, 1991Date of Patent: February 23, 1993Assignee: Hitachi, Ltd.Inventors: Keiji Ohmura, Sumio Okuno, Kentaro Masai, Hideshi Ooba, Senzoo Hida, Seiichi Okamoto

Patent number: 5113769Abstract: A car body for high speed railway rolling stock and a method of fabricating the same wherein, in order to prevent a variation of external pressures produced when the rolling stock travels at high speeds from being propagated into the interior of the car body, the car body is of an air-type construction. The car body has a reduced weight and is capable of withstanding a variation of the external pressures by the provision of a construction in which the underframe of the car body includes a curved surface having at least one radius of curvature extending across a width of the car body.Type: GrantFiled: June 6, 1989Date of Patent: May 19, 1992Assignee: Hitachi, Ltd.Inventors: Sumio Okuno, Michifumi Takeichi, Keiji Ohmura, Msato Okazaki, Hitoshi Tsuruda, Hiroyuki Yamada, Morishige Hattori, Kenji Kimura

Patent number: 5109777Abstract: A car body for railway rolling stock wherein a plurality of outside plates forming the car body are joined to frame members of the car body by spot welding. The outside plates are produced of a ferrous material except for stainless steel and a film or coating is provided on an outside surface of the outside plates. By virtue of the joining of the outside plates to the frame members and the joining of the outside plates to each other by spot welding, less input heat is required as compared with a continuous welding; therefore, outside plate distortion can be reduced and time and labor for manufacturing of the car body can be reduced. Moreover, since the outside plates are produced of a ferrous material, the painting of the outside surfaces of the outside plates can easily be accomplished.Type: GrantFiled: August 9, 1990Date of Patent: May 5, 1992Assignee: Hitachi, Ltd.Inventors: Keiji Ohmura, Sumio Okuno, Michifumi Takeichi, Kentarou Masai, Seiichi Okamoto, Masatake Nakamura
