Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates gaps and steps between the entrance and exit of a railway vehicle and a platform, and facilitates getting on and off with a wheelchair or the like, and is most suitable for use in combination with a platform door. The present invention relates to a getting-on / off assistance device.

[0002]

2. Description of the Related Art When a railway vehicle stops at a straight line, the distance between the platform end and the entrance of the vehicle is relatively short. There was a considerable amount of space between the platform edge and the vehicle entrance at such places, and there was a danger that passengers would fall onto the railroad tracks. In addition, the floor of the vehicle is usually higher than the platform, and this step has hindered getting on and off in a wheelchair.

[0003] As a method of solving such a problem,
For example, the one disclosed in Japanese Patent Application Laid-Open No. 2-212257 discloses that, while the vehicle is stopped, the movable tread moves diagonally upward and rises up to the platform surface, so that the gap between the platform and the entrance of the stopped vehicle is removed. It aims to reduce the number of passengers and prevent passengers from falling, and to eliminate the step between the vehicle floor and the platform. In addition, for example,
Japanese Unexamined Patent Publication No. 7-108926 and Japanese Patent Application Laid-Open No. 7-108927 disclose a step plate that can be moved forward and backward and tiltable between a floor surface of a vehicle and a platform surface, and the step plate moves forward while the vehicle is stopped. To reduce the gap between the platform and the entrance of the stopped vehicle to eliminate the step.

[0004]

According to the method disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-212257, the movable tread plate rises obliquely upward from below the platform, so that the platform needs to be dug deeply, and installation work is required. There was a problem that the cost was very high. In addition, when trying to reduce the level difference between the tip of the movable tread and the vehicle floor when the movable tread advances, the inclination of the movable tread may become steep, which may hinder getting on and off by a wheelchair. JP-A-7-10
No. 8926, Japanese Unexamined Patent Publication No. Hei 7-108927 discloses that a tilting device for tilting a step plate and an advance / retreat drive device for moving the step plate forward / backward are arranged in the same body, and the device configuration is extremely high. It was complicated.

[0005] Further, all of the above-mentioned conventional examples have a function of reducing the gap between the platform and the vehicle and eliminating a step with the floor of the vehicle. It is not necessary to install a home step having a function of reducing the gap and eliminating a step (hereinafter, referred to as a “step and clearance eliminating type home step”) in all places of the platform, and the step is provided in a necessary place. In addition, a home step with a function to reduce only the gap between the platform and the entrance of the stopped vehicle (hereinafter referred to as a “gap-elimination type home step”) is installed in other places. In most cases, it should be good. Therefore, it is desirable to provide a getting-on / off assist device that can easily cope with such a change in specifications. The conventional getting-on / off assistance device cannot sufficiently cope with such a demand.

Further, in recent years, the number of accidents of falling from the station platform has increased, and as a countermeasure, the number of stations having platform doors on the platform has increased. For this reason, it is desired that the above-mentioned getting-on / off assistance device and the home door are integrally formed. In particular, in consideration of safety at the time of getting on and off, it is desirable that when the home door is closed, the step plate (movable tread plate) of the above-mentioned getting on and off assist device is operated to reduce the gap and eliminate a step. The present invention has been made in view of the above circumstances, and it is an object of the present invention to have a relatively simple apparatus configuration, facilitate installation work, and easily respond to a change in apparatus specifications. And a boarding / alighting assistance device that can be integrated with a home door.

As described above, it is slidably mounted in the home step unit. When the vehicle is stopped, it moves forward toward the entrance / exit, and when the vehicle is absent, the step that retreats into the home step unit can be slid into the home step unit. And a first drive mechanism for moving the step forward / backward is provided in the home step unit, and a second drive mechanism for raising / lowering the vehicle side end of the home step unit is provided on the home door. Since it is housed in the door pocket, if the second drive mechanism is removed, it can be used as a gap eliminating type home step as it is, and it is possible to easily cope with a specification change.
