20130152820 | BODYSHELL STRUCTURE OF RAILCAR - The present invention is a bodyshell structure of a railcar, the bodyshell structure including a plurality of side window opening portions formed on a side bodyshell along a railcar longitudinal direction, and the side window opening portions include a plurality of large window opening portions arranged on a railcar-longitudinal-direction center portion of the side bodyshell and a plurality of small window opening portions arranged on both railcar-longitudinal-direction sides of the large window opening portions and each having a smaller opening area than the large window opening portion. | 06-20-2013 |
20130213259 | FLOOR STRUCTURE OF RAILCAR - Provided is a floor structure of a railcar in which thickness of a heat insulating material can be reduced while having predetermined heat resistance. The floor structure of the railcar includes a underframe having a pair of side sills extending in a railcar longitudinal direction and a cross beam arranged between the side sills and extending in a railcar width direction, a structural floor provided on an upper surface of the underframe, and a first heat insulating material arranged on a lower side of the structural floor via an air layer for the structural floor. | 08-22-2013 |
20130220169 | UNDERFRAME STRUCTURE OF RAILCAR - An underframe structure of a railcar capable of reducing a deformation amount of a cross beam supporting an underfloor equipment upon underfloor fire. The underframe structure of the railcar includes an underframe having a pair of side sills extending in a railcar longitudinal direction and a cross beam arranged between the side sills and extending in a railcar width direction, a structural floor provided on an upper surface of the underframe, and an underfloor equipment suspended down in a center part in the railcar width direction of the cross beam. The underframe structure includes a passenger cabin floor provided on an upper side of the structural floor, the passenger cabin floor forming a lower surface of a passenger cabin S, and floor receiving members supporting the passenger cabin floor and extending in the railcar longitudinal direction between the structural floor and the passenger cabin floor. | 08-29-2013 |
20130233200 | CRASH ENERGY ABSORBER OF RAILCAR - A crash energy absorber is provided at a front portion of a carbody of a railcar and configured to crush by a load from a front side to absorb crash energy. The crash energy absorber includes: a main absorbing portion extending in a front-rear direction; and a pair of sub absorbing portions respectively provided at upper and lower sides of the main absorbing portion. Each of the pair of sub absorbing portions is formed integrally with the main absorbing portion via breakable portions each extending in the front-rear direction. | 09-12-2013 |
20130239847 | OBSTACLE DEFLECTOR OF RAILCAR - An obstacle deflector provided at a front portion of an underframe of a carbody of a railcar includes an obstacle deflecting plate configured to protect the carbody from an obstacle on a railway track when the railcar is traveling. The obstacle deflecting plate includes a main plate portion provided to receive the obstacle by a surface thereof and having a curved shape that is convex toward a front side in a traveling direction in plan view and a sub plate portion projecting toward a rear side from the main plate portion and is continuously provided along the main plate portion so as to extend from a convex, curved front end portion of the main plate portion toward a pair of left and right side portions of the main plate portion, the left and right side portions being located at the rear side in the traveling direction. | 09-19-2013 |
20150203129 | RAILCAR - A railcar according to the present invention includes: an underframe including an end beam at its railcar-longitudinal-direction end portion; side bodyshells; a roof bodyshell; side outside plates respectively arranged at both railcar-width-direction end portions of the railcar and constituting the side bodyshells; corner posts extending from the end beam toward the roof bodyshell; and intermediate coupling members each configured to couple the side outside plate and the corner post, the stiffness of the intermediate coupling member in a railcar longitudinal direction being lower than the stiffness of the intermediate coupling member in a vertical direction. | 07-23-2015 |
20160137272 | DOUBLE-SHELL TANK AND LIQUEFIED GAS CARRIER SHIP - A horizontal type cylindrical double-shell tank includes an inner shell and an outer shell. The inner shell includes an inner shell main part storing a liquefied gas and an inner shell dome protruding from the inner shell main part. The outer shell forms a vacuum space between the inner shell and the outer shell, and includes an outer shell main part surrounding the inner shell main part and an outer shell dome surrounding the inner shell dome. The inner shell dome is provided with an inner shell manhole. The outer shell dome is provided with an outer shell manhole at a position corresponding to a position of the inner shell manhole. | 05-19-2016 |
