Publication number: 20150135987Abstract: A railcar includes a side sliding door and entrance peripheral-member surrounding the side entrance. The entrance peripheral-member includes a door pocket post in which outer and inner portions are inwardly of the outer portion in car-width direction coupled to each other. The side sliding door peripheral portion is pressed against an edge portion, extending along the side entrance of the entrance peripheral-member via a rubber seal at the side entrance closed state. In the side entrance open state, the side sliding door is pulled into a door pocket space facing the door pocket post inner portion. A portion projecting inwardly in car-width direction beyond the inner portion and including a tip end contacting the rubber seal provided at at least part of region constituted by portions of upper and lower edges of the side entrance peripheral-member and lateral edge at the edge portion door pocket post side of the entrance peripheral-member.Type: ApplicationFiled: June 11, 2013Publication date: May 21, 2015Inventors: Naoaki Kawakami, Shinichi Okada, Naohiro Yoshida, Kazumasa Inaba, Kenji Waki

Patent number: 8931418Abstract: A bodyshell of a railcar includes side outside plates, end bodyshells, and guiding plates. The side outside plate are located at both end portions of a carbody in a vehicle width direction. The end bodyshell includes an end outside plate and a corner post. The end outside plates are located at both end portions of the carbody in the longitudinal direction. The corner posts are located at four corners of the carbody. The corner post is joined to the adjacent end outside plate and the adjacent side outside plate. The guiding plate is provided at the side outside plate so as to cover the corner post from a vehicle exterior. The guiding plate includes an inclined portion and a joining portion. The inclined portion is provided in front of the corner post and inclined to the rear side toward the side outside plate.Type: GrantFiled: April 21, 2010Date of Patent: January 13, 2015Assignees: West Japan Railway Company, Kawasaki Jukogyo Kabushiki KaishaInventors: Masayasu Matsuoka, Hiroyuki Kido, Taro Hayashi, Makoto Taguchi, Toshiyuki Yamada, Naoaki Kawakami, Yasufumi Minamimoto, Akira Ukita, Masami Hayashida

Patent number: 7926370Abstract: A rotation and extension/retraction link mechanism which realizes a rotary joint having a virtual rotation axis is provided. A rotation and extension/retraction link mechanism 1 is configured so that a first link 5 having a first virtual center line 3 and a second link 9 having a second virtual center line 7 are coupled through a rotation and extension/retraction joint mechanism 11. The rotation and extension/retraction joint mechanism 11 is configured to couple the first link 5 and the second link 9 so that when the second virtual center line 7 rotates relative to the first virtual center line 3 from a state where the first virtual center line 3 entirely overlaps with the second virtual center line 7, while crossing the first virtual center line 3, an intersection between the first virtual center line 3 and the second virtual center line 7 is displaced on the first virtual center line 3 by a predetermined distance corresponding to an angle of the rotation.Type: GrantFiled: December 17, 2004Date of Patent: April 19, 2011Inventors: Ichiro Kawabuchi, Susumu Tachi, Naoaki Kawakami
