Abstract

PROBLEM TO BE SOLVED: To solve the problem that a passenger drops between a platform and rolling stock if a step of a getting-on-and-off assist device protruding toward the rolling stock is stored when the passenger is on the step. SOLUTION: A matlike load detection raw material in which electrical conductive parts of opposing printed wiring boards keep a gap by a cushion material to detect a load due to the contact of the electrical conductive parts by the load is provided on an upper face of a part which becomes a stepping face when the step advances toward the place where passengers get on and off to constitute the step so as to eliminate storage operation when detecting the load.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boarding / alighting assisting device for reducing a gap between a platform of a railway vehicle and a platform to prevent the vehicle from falling off when getting on and off.

[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 on the tracks.

[0003] As a method for solving such a problem, a platform assist device is embedded at a position corresponding to the vehicle entrance of the platform. Move forward,
There is a way to act as a bridge between the platform and the vehicle entrance. Hereinafter, the outline will be described with reference to the drawings.
FIG. 4 is a top view showing the positional relationship between the entrance of the vehicle and the getting-on / off assist device on the platform. The boarding / alighting assist device includes a storage unit 2, a step 3, and a drive mechanism for driving the steps, but the drive mechanism is omitted because it is not directly related to the present invention.

[0004] Reference numeral 4 denotes a vehicle, and reference numeral 5 denotes a vehicle-side door. FIG. 5 is a cross-sectional view of FIG.
It is a figure which shows A, and 6 is a floor surface of a vehicle. FIG.
1 have the same functions and the same structures. By the way, there is a possibility that the passenger on the step may fall between the platform and the vehicle if the step is stored in the storage unit when the passenger is on the step.

[0005]

As the simplest method for solving such a problem, there is a method for detecting the presence of a passenger using a light-emitting element and a light-receiving element. The portion surrounded by a dotted line in FIG. A light emitting element, a light receiving element, a mounting member for the light emitting element, a light receiving element, and the like cannot be installed due to restrictions of a vehicle limit and a building limit. So, irradiate light from the ceiling toward step 3,
A method is conceivable in which the presence of the passenger is detected by changing the reflected light depending on the presence or absence of the passenger. However, the method of detecting with light is susceptible to the influence of ambient lighting, the influence of snow and rain, the influence of dirt on the step surface, and the like,
It could not be detected accurately.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem. The present invention has been made so that the upper surface coincides with the platform surface at a position on the platform corresponding to the entrance of a stopped vehicle. A storage unit provided in the storage unit, which is provided toward the entrance when the vehicle is stopped, and is stored in the storage unit when the vehicle is absent. Comrades keep the gap with cushioning material,
The step is provided by providing a mat-shaped load detecting material for detecting the load when the conductive portions come into contact with each other due to the load on the upper surface of a portion that becomes a tread surface when the step advances toward the entrance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. FIG. 1 is an example of a cross-sectional view of a mat-shaped load detecting material used in the present invention. In the figure, reference numerals 11 and 12 denote printed circuit boards, which are arranged so that printed foils serving as conductive portions face each other. 13, elastic cushioning material,
Numeral 14 is a plate for keeping the level. Reference numeral 15 denotes a plate member to receive a load, and polyurethane or the like is used. The plate 16 is generally made of the same material as that of the plate 15, but may be omitted if the plate 14 satisfies the strength, weatherability, and other properties.

The detected load can be freely selected depending on the elastic modulus and the mounting density of the cushion material 13, and it is possible to assume that a child up to about 3 years of age can independently get on and off without a companion. If it is about the body weight, it can be sufficiently detected. The right diagram in FIG. 1 shows a state in which the printed foils of the opposing printed circuit boards come into contact with each other under a load. FIG. 2 is a functional block diagram for detecting a load, and a portion represented by a switch in the figure corresponds to a facing printed foil. FIG.
In step 3 based on the present invention,
17 shows a state where 17 (corresponding to 11 to 16 in FIG. 1) is attached, and is shown so that the inside of the storage section can be seen.

The mat-type load detecting material 17 may be attached by bonding or may be sandwiched between metal plates attached to the left and right of the step. Of course, it is also possible to use the portions of the printed boards 11 and 12 that do not have a foil to screw them. According to the present invention, when there is a passenger on the mat sensor 17, the function of storing the step 3 in the storage unit 2 is cut off, so that the passenger can be prevented from falling. Also, compared to the case of detection using light, it is possible to perform detection with extremely high accuracy without the influence of surrounding illumination, the influence of snow, rain, and the like.

[0010]

According to the present invention, it is possible to accurately detect whether or not a passenger is on a step advancing toward a vehicle. This makes it possible to prevent a problem that the steps are stored in the storage section, and it is possible to prevent a dangerous accident that a passenger falls down.
