Description

{SAFETY FOOTHOLD FOR TRAIN PLATFORM}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pedestrian safety footrest which can prevent accidents and falls due to a passenger's foot drop in a space separated between a train and a platform.

Such a platform safety footrest is configured so that when the train is opened, the train is opened and then the train door is closed so that the train can be released. When the platform safety door is closed, the safety footrest can be returned to its original position without improving the structure of the train platform And is configured so as not to interfere with the entry / departure of the train.

Generally, when you look at the train station, there is a platform where the passengers can wait and board, and a line section where the train runs on one side of the platform.

These railway stations are equipped with (a) a platform where only a platform and a train entry section are provided, (b) a platform door for safety is installed in the platform, but a space where the space between the platform and the platform is widely formed (c) It can be classified as a place where the landing door is installed, and the space of separation between the landing area and the train entry area is narrow.

(B) There is a platform and a platform door for safety. However, there is a reason why the space where the space between the platform and the entrance of the train is wide is opened periodically. However, There is inevitably a wider spacing space to enter together.

However, since there is a space between the landing area and the train entry area as described above, there is a possibility that the occupant who is walking and boarding may be injured by a foot drop accident. A user who is aboard a vehicle accompanied by a tool such as a cap or wheelchair, There is a problem that it is difficult to ride without assistance.

As described above, in order to solve the inconvenience of the space between the landing platform and the train, a safety flooring technology for use in a space between the platform and the train has been developed.

Regarding the above technique, Japanese Patent Application No. 10-1100089 discloses a safety footrest for a train, which can be referred to FIG. 5 of the accompanying drawings.

5 includes a pair of brackets 100 installed on a wall 20 on the railway side of a train platform 10 and having a through hole 110 formed thereon, A supporting portion 210 provided between the bracket 100 and positioned between the railway platform 10 and the train 30 to support a passenger and a rotation hole 220 communicating with the through hole 110 are formed A rotating shaft (300) fitted in the pair of through holes (110) and the rotating hole (220) so that the footrest (200) is rotated; And the upper end is installed on the lower surface of the foot plate 200 and the lower end is installed on the wall 20 on the railway side of the train platform 10 so that the length thereof is adjusted to approach the entrance of the train 30, And a length adjusting part 400 for lowering the support part 210 when the door 30 is not yet opened and spaced from the entrance of the train 30. [

The above technique is formed on the side of a railroad entrance line of the landing platform as shown in FIG. 5 of the accompanying drawings, and protrudes directly on the side surface, which may interfere with entry of a train.

In other words, the gap between the platform and the line is predetermined. To apply the above technique safely, there is a danger that the structure of the platform should be partially improved, or otherwise the device may collide with the train during entry, It is necessary to utilize the empty space of the platform in order not to obstruct it, or to apply the structure in a line that does not improve the structure of the platform, which does not reflect this point at all.

Therefore, it is required to develop a technique that can easily ride on a train by driving a safety footrest as a structure that does not affect entry or advancement of a train in the event of emergency.
