Patent number: 8689703Abstract: A weld-joining structure between an outer panel and an attachment is achieved, which is advantageous in terms of appearance, workability, and cost. To weld-join the outer panel and the attachments including, such as frame members and opening frames and opening frame members, which is a reinforcement or an interior or exterior member for use in the outer panel, the outer panel and the attachment placed on the outer panel are weld-joined by laser welding at overlapping portions of the outer panel and the attachment. The laser welding is performed along a polishing mark formed in one direction on an externally exposed-side surface of the outer panel and the attachment.Type: GrantFiled: November 30, 2006Date of Patent: April 8, 2014Assignee: The Kinki Sharyo Co., Ltd.Inventors: Hiroji Harada, Yoshinori Kono, Tomonori Sumikawa, Hiroshi Yonetani, Yasuhiro Tanaka, Eiichi Kato

Patent number: 8297202Abstract: To join vertically and horizontally arranged frame members to the interior face of an outer panel, the horizontal frame members are disposed on the outer panel so as to take precedence over the vertical frame members and are weld-joined to the outer panel. The vertical frame members are placed on the horizontal frame members from the interior side and are weld-joined to the horizontal frame members. The vertical frame member includes a standard-width frame member and a wide-width frame member having a width greater than the width of the standard-width frame member. The vertical frame members are joined to and in contact with the outer panel at a reduced number of points, so that the appearance of the outer panel is maintained in a good condition. With this configuration, a low cost vertical and horizontal frame structure is achieved, which has sufficiently high joint strength that provides the required strength of the outer panel.Type: GrantFiled: December 6, 2006Date of Patent: October 30, 2012Assignee: The Kinki Sharyo Co., Ltd.Inventors: Yoshinori Kono, Tomonori Sumikawa, Hiroshi Yonetani, Eiichi Kato

Patent number: 8240255Abstract: A body frame structure having practically sufficient strength is provided. The body frame structure has a simple structure that can be obtained by simple joining operation. Vertically and horizontally arranged first and second frame members are weld-joined to an outer panel with an end portion of the second frame member facing a side surface of the first frame member. The first frame member is placed in a straddling manner on the outer panel and the end portion of the second frame member weld-joined to the outer panel and is weld-joined to both the second frame member and the outer panel. In this manner, even when the vertically and horizontally arranged first and second frame members are laser-welded to the outer panel, the joint strength can be improved without using a joint plate.Type: GrantFiled: November 30, 2006Date of Patent: August 14, 2012Assignee: The Kinki Sharyo Co., Ltd.Inventors: Hiroji Harada, Tomonori Sumikawa, Yasuhiro Tanaka, Eiichi Kato
