The second connecting shaft is formed on the lower surface of the movable scaffold. When the second link is rotated in the upward direction by the roller, the first link is operated in the upward direction, and the second connecting shaft pushes the movable scaffold.

The second link further includes a swash plate on the lower surface thereof. The swash plate is configured to be inclined in the direction of the first linking axis in the second link axial direction, and is configured to adjust the height of the movable stepping plate in accordance with the distance to which the shaft is advanced It is a technical feature.

Generally, when you look at the train station, there is a platform where the passengers can wait and board, and a section where the train can enter at 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.

In connection with the above technique, Japanese Unexamined Patent Application Publication No. 10-2005-0110890 (prior art 1) discloses an urban railroad win-and-leave safety footrest. The safety footrest is provided at the bottom of the side end of the platform, And a supporting plate which is provided between the upper and lower plates by means of friction between the driving means and the upper and lower plates by means of friction between the driving means and the lower plate. The lower portion of the groove and the entrance of the train into the ceiling of the platform, A sensor for checking the opening and closing of the door is provided so that the auxiliary footrest is pulled out by the driving means when the train enters and the auxiliary footrest is inserted when the door of the train is closed, By relieving the impact when stepping on the auxiliary footrest, it is possible to prevent the occurrence of a failure, and to allow the auxiliary footrest to come in and out by friction with the rollers By inserting the auxiliary footrest by hand when the driving motor is not working, it is possible to start the train even in the event of a breakdown. Also, the city railway which can easily get on and off by the handicapped using wheelchair, .

The prior art 1 can refer to FIG. 7 of the accompanying drawings. The prior art 1 according to FIG. 7 has a predetermined problem because the footrest is driven by a sliding operation.

For example, since the floor of the platform and the floor of the door of the train are different in height depending on the position of the platform and the abrasion condition of the train wheel, even if a safety footrest is provided in the space between the platform and the train, There is a problem that it is not easy to get up and down.

However, the above-described problems can not be solved by the prior art 1 described above.

Regarding other techniques, a safety footrest for a train is described in Patent Publication No. 10-1100089 (Prior Art 2), which can be referred to Fig. 8 of the accompanying drawings.

Prior Art 2 of FIG. 8 shows a pair of brackets 100 installed on a wall 20 on the side of an iron 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 train 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. [

8 of the accompanying drawings, it is not possible to adjust the height of the footrests as it is not a slide type as in the above-described prior art 1. However, since the length adjuster 400 is configured in the form of a telescope, It can not be raised above a certain height.

8, in the prior art 2, it can be seen that the length adjuster 400 is provided in a state in which the footrest 200 is positioned on a straight line with the upper surface of the railroad platform 10. If the footrest 200 The piston portion 420 of the length adjusting portion 400 may be further exposed from the cylinder portion 410 so that the piston portion 420 and the cylinder portion 410 may be further exposed, There is a problem that the foot plate 200 is not completely folded due to the length of the foot plate 410. Such a problem may cause a secondary accident due to a collision with a train.

Therefore, in relation to the construction of the safety footrest which can easily ride the train by adjusting the height of the safety footrest even if the height of the platform floor and the bottom of the train door are different from each other, Is required.

The shaft 22 may be formed with a roller 23 at one end exposed from the body 21. At this time, the roller 23 is formed at one end of the shaft 22 and is configured to be rotatable in the circumferential direction on its outer surface.

A support member 24 for supporting the platform safety footrest according to the present invention may be provided on the side of the line of the platform 20 along the line side surface of the platform.

The support member 24 may be fastened through the platform 20, the bolt and the nut as shown in the accompanying drawings.

The roller 23 can push the second link according to the forward and backward movement of the shaft 22 so that the movable footrest can be operated. To this end, the present invention includes the movable footrest shaft 31, the movable footrest 32, A second link shaft 33, a second link 34, a first connecting shaft 35, a swash plate 36, a first link 37, and a second connecting shaft 38. [

The movable footrest shaft 31 is formed at a position corresponding to the uppermost surface of the platform 20 among the one side of the support member 24 and can perform a shaft function serving as a reference for the operation of the movable footrest 32. [

That is, the movable footrest 32 may be configured to be rotated about the movable footrest shaft 31.

The second link shaft 33 is configured on one side of the support member 24 on the opposite side from which the movable footrest shaft 31 is configured to perform an axis function as a reference for the operation of the second link 34, can do.

Meanwhile, although not shown in the accompanying drawings, the platform safety footrest according to the present invention may include a detection sensor for detecting entry of a train.

Such a sensor is sufficient for applying a sensor for achieving the object of train detection, and may be constituted by a sensor device such as an infrared sensor, an object detection sensor, or a camera device.

However, if the safety footrest 30 is operated by detecting the entry of the train, the safety footrest 30 may be damaged by collision with the train, or a secondary accident may occur due to the breakage of the train,

(a) When the train is detected by the detection sensor, the safety footrest 30 is operated at a time when the train is stopped by applying a predetermined time (configuration is made so that the detection value is outputted after a predetermined time after the train is detected) (For example, 30 seconds to 1 minute) until the train enters and stops,

(b) Rather than detecting the arrival of a train, it can be configured to sense a stop after the train has entered (a train is detected but a detected value is output if there is no movement).

For this purpose, it can be configured to be linked to a system for notifying the existing train entry.

Hereinafter, an operation of the platform safety footrest according to the present invention will be described with reference to FIGS. 2 to 5 of the accompanying drawings.

2 to 4 show that the movable footrest is operated in the footrest safety footrest according to the present invention.

And FIG. 5 is a front view and a side view, respectively, of the operation of the safety footrest in the landing safety footrest according to the present invention.

FIG. 2 of the accompanying drawings shows a case where a train stops on a straight line (straight line). In this case, it can be seen that the movable footrest 32 is positioned on a straight line with the floor surface of the landing platform.

3 shows a case where a train stops on a curved line (curved line) and the floor of the door of the train is located higher than the height of the landing floor. In this case, So that the end of the movable footrest 32 can be elevated to the bottom of the door of the train.

4, the train 23 stops at a curved line (curved line), and the bottom of the door of the train is located lower than the height of the landing floor. In this case, The end of the movable footrest 32 can be lowered and adjusted so as to be adjacent to the floor of the door of the train by pushing it less than when stopped on a straight line.

The operation of the movable footrest 32 may be enabled by adjusting the height at which the second link 34 can be pivoted when the roller 23 is pushed by the configuration of the swash plate 36 as described above.

The reason why the height of the movable footrest 32 should be adjustable is as follows. (A) Although the railway line of the landing area may be formed as a straight line, it may be formed of a curved line. (B) the height of the floor of the platform may differ from the floor height of the train door due to wear of the train wheels.

The height adjustment of the movable footrest 32 can be performed through a sensing sensor, which is installed on the side of the landing side of the platform, outputs an output beam such as an infrared ray in a radial form, The height of the floor of the door of the train can be determined by receiving the output beam.

To this end, it is preferable that the detection sensor is installed on the uppermost side of the line side of the platform, and it is possible to determine how high or low the floor of the door of the train is based on the position of the detection sensor And the operation of the shaft 22 can be controlled.

The height of the floor of the door of the train is determined according to the sensor value, and the control of the shaft 22 can be performed through the control device provided in the body 21 described above.

The height of the movable footrest 32 can be automatically operated in association with a server (not shown in the drawing) of the landing platform 20 that manages train information entering the landing platform 20 according to other design conditions For example, the type of the train entering the time according to the information of the server, the interval between the train and the landing platform 20, and the difference in floor height between the train and the landing platform 20, And such a control device can be configured inside the body 21. [0050]

Further, depending on the design conditions, it is possible to further protect the passenger from the landing 20 or the current flowing in the train by further including an insulating plate on the upper surface of the movable footrest 32, which is shown in FIG. 6 of the accompanying drawings.

6 is a view showing that an insulating plate is attached to a movable footrest of a pedestrian safety footrest according to the present invention.

At this time, on the surface of the insulating plate, plural irregularities (not shown) may be repeated in a predetermined pattern in order to prevent slipping.

1 to 6 are merely the main points of the present invention. As various designs can be made within the technical scope of the present invention, the present invention is limited to the configurations of Figs. 1 to 6 It is self-evident.
