Footplate of gangway and railway car

Abstract

The invention provides a thin footplate of superior quality while suppressing noise caused by the footplate. A footplate 10 is formed by connecting extruded shape members 110 arranged in parallel along the width direction of a railway car by a pipe 80, with the upper surface of the extruded shape members 110 used as the walking surface. Adjacent extruded shape members 110 contact each other via bushings 90. Both ends of the pipe 80 are pulled via draft springs 50 and 50 disposed in V-shape onto the underframe. A slip stopper 120 is adhered to the upper surface of the extruded shape members 110. Bottom surfaces of the extruded shape members contact the upper surface of the underframe via sliding members 70. When the railway car passes a curve or the like that causes relative displacement of the cars, the footplate 10 is slid easily. When one of the railway cars is subjected to rolling, each extruded shape member gradually rotates (rolls) along the width direction of the railway car so that crews and the like can easily walk on the footplate.

Description

[0001] The present application is based on and claims priority of Japanese patent application No. 2004-337333 filed on Nov. 22, 2004, the entire contents of which are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a footplate of a gangway provided at a connecting portion of railway cars connected to form a train formation. [0004] 2. Description of the Related Art [0005] 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. [0006] Generally, as disclosed in Japanese Utility Model Publication No. 50-43848 (patent document 1), 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 longitudin...

AI Technical Summary

Benefits of technology

[0014] 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.

Problems solved by technology

Such conventional gangway is not especially appropriate for application to the latest railway cars that are required to have superior outer appearance.

Therefore, in comparison to the passenger cabin with improved interior and exterior design, the design of the gangway has not been improved for a long time.

Especially, according to the gangway disclosed in patent document 1 in which the plates provided at ends of railway cars are overlapped with one another, the vibration and the displacement of railway cars during movement of the train causes noise to be generated from the footplates.

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.
