Definitions

  • the present invention relates to a footplate of a gangway provided at a connecting portion of railway cars connected to form a train formation.
  • a gangway is provided at ends of respective cars of a train formation in which railway cars are connected to form a train, so as to enable easy and safe movement of passengers from one car to another.
  • the gangway is composed of a footplate connected at a longitudinal end of a railway car and overlapped with another footplate, and a bellows connected to the longitudinal end of the railway car to cover the gangway at the longitudinal end of the railway car.
  • Such conventional gangway is not especially appropriate for application to the latest railway cars that are required to have superior outer appearance.
  • Japanese Patent No. 3060367 discloses an art that is aimed at solving the problem and to provide improvement of the appearance.
  • the footplate is placed on an end of the adjacent railway car. Rollers are provided at the bottom surface of the footplate that enable the footplate to move in the width direction when one railway car is displaced in the width direction with respect to another railway car.
  • a wide gangway in the width direction can be formed.
  • the disclosure of patent document 2 solves the above-mentioned problem of the footplates.
  • the footplates disclosed here is arranged so that the footplates deform into a parallelogram when the adjacent car bodies are displaced in the width direction, and requires rollers for supporting the footplate structure, so the thickness of the whole footplate structure is relatively large. Therefore, it is applicable to railway cars in European countries having a relatively large distance between the upper surface of the floor of the railway car and the upper surface of the coupler, but since the railway cars in Japan have couplers that have a height higher by approximately 200 mm than the railway cars in Europe, so the distance between the upper surface of the floor of the railway car and the upper surface of the coupler is not large enough to adopt the disclosed footplate structure.
  • the object of the present invention is to provide a footplate that has a relatively small thickness and generates only a small noise, to improve the overall quality of the gangway including the footplate.
  • a footplate provided on a floor of a gangway at a connecting portion between railway cars to enable passengers and the like to move from one car to another, the footplate comprising: a plurality of flat panels disposed in parallel along a longitudinal direction of the railway car that are connected by a connecting member disposed along a width direction of the railway car; wherein the plurality of flat panels are capable of rotating around the connecting member.

  • the plurality of extruded shape members 110 form a floor surface on which crews and the like can walk easily.
  • the length of the extruded shape member 110 is greater than the space between the adjacent cars.
  • the length of the shape member 110 is approximately 700 mm.
  • holes 111 are formed to both side surfaces of the extruded shape member, and the cylindrical portions of bushings 90 , 90 are passed through each of the holes 111 , 111 .
