Description

The present invention relates to a thin light emitting block that is installed on a platform of a station and emits light.

On the platform of the station, a thread line for blinking is embedded in the longitudinal direction along the track of the platform, for example, as a device for calling attention to prevent falling on the track.

Patent Document 1 discloses a platform tile in which an LED light emitter is embedded. The thread line that crosses from one end of the tile to the other end is composed of a plurality of LED light emitters arranged at predetermined intervals. By exchanging the platform tiles of Patent Document 1 with the tiles arranged on the existing platform, a thread line composed of LED light emitters can be newly installed on the platform.

It is composed of a plurality of vertical frame portions, the base portion is composed of two block pieces, and at least one block piece of the two block pieces is the flat plate portion to which the horizontal frame portion is fixed. It is solidified with a solidified body so as to surround the horizontal frame portion and the vertical frame portion, and is characterized in that the back surface portion of the bottom portion of the groove portion and the back surface portion of the two block pieces are flush with each other. And.

The thin light emitting block according to the present invention can be made thinner while maintaining the strength of the main body by connecting the left and right block pieces by the chassis portion integrated with the skeleton portion. In addition, the back surface of the chassis and the back surface of the block piece can be flush with each other, and by providing a power supply hole at the bottom of the groove of the chassis, it is easy to wire the power line to the lower part of the platform.

FIG. 4 is a perspective view showing a state in which a block piece portion of the thin light emitting block 1 adopting a different chassis portion 3'of the second embodiment is transmitted. The difference from the thin light emitting block 1 of the first embodiment is that the flat plate portion 3e'in which the width substantially matches the lateral width of the block piece portion 2b without providing the horizontal frame portion 3b'and the vertical frame portion 3c on the block piece portion 2b side. Is adopted.

The structure other than the flat plate portion 3e'is the same as that of the thin light emitting block 1 of the first embodiment, and by adopting the flat plate portion 3e', the fixing work of the horizontal frame portion 3b'and the vertical frame portion 3c becomes unnecessary and the cost is reduced. Leads to.

Further, a plurality of holes 3j are formed at predetermined intervals on the surface of the flat plate portion 3e'. These hole portions 3j realize weight reduction and cost reduction while maintaining the strength of the flat plate portion 3e'. Further, when the solidified body is solidified so as to surround the flat plate portion 3e', the solidified body is solidified even in the hole portion 3j, which has the effect of increasing the adhesiveness between the flat plate portion 3e'and the block piece portion 2b.

A plurality of holes 3j are appropriately bored in the flat plate portion 3e on the block piece portion 2a side or the flat plate portion 3e of the thin light emitting block 1 of the first embodiment so as not to weaken the strength of the plate material. May be good.

The same reference numerals as those in the first embodiment indicate the same members and the same parts.

In this way, the plurality of thread line portions 4 of the thin light emitting block 1 are connected in parallel in a string of beads, and the plurality of thread line portions 4 are connected so as to be linear.

Normally, the tip tile T having the non-slip portion S is arranged on the track side of the end portion E of the platform P with respect to the thin light emitting block 1. Then, a thin light emitting block 1 is adjacent to the inside of the tip tile T, and passengers stand by or move to the side opposite to the line side of the protrusion 2d, which is the inner line of the thin light emitting block 1.

In addition to the thin light emitting block 1 that can be replaced with the existing block for the blind, the thin light emitting block 1 in which the block for the blind and the tip tile T are connected and integrated may be used, and the existing block for the blind and the tip tile T may be combined. It can also be replaced with the integrated thin light emitting block 1.

Regarding the connection procedure of the power supply control device C, it is possible to take in the power supply line D from the power supply control device C from below the thin light emitting block 1. When taking in the power line D from below the thin light emitting block 1, first, of the existing blocks for blind people to be replaced, the block for blind people at the end is removed, and the lower part is hollow and becomes a base K made of concrete or the like. On the other hand, a through hole H having a diameter of about 5 cm is drilled using a drill or the like.

Subsequently, a cylindrical protective tube G having a diameter of about 2 cm is attached to the power supply hole at the bottom 3f of the chassis main body 3a from the outside, and the protective tube G is installed so as to be inserted into the through hole H. A power line D is internally provided in the protective tube G, and the thread line portion 4 is horizontally connected in a string connection via the connector portion and the connector receiving portion, and the connector receiving portion of the thin light emitting block 1 at the end is connected. The other end of the power supply line D extending through the power line D is connected to the power supply control device C installed outside.

By controlling the power supply of the power supply control device C, the light emitting unit 4a of the connected thread line unit 4 can be controlled to turn on and off in synchronization, and the through hole H can be formed in the base portion K. The power line D with respect to the thread line portion 4 can be easily wired by using the space under the platform P.

When a train interlocking device is connected to the power control device C and a train approach signal is input, the thread line portion 4 of the thin light emitting block 1 is controlled to blink for a predetermined time, or an emergency battery is built into the power control device C. Further, when the power supply to the power supply control device C is stopped, the thread line unit 4 can be continuously turned on to illuminate the feet by using the emergency battery.

Further, in addition to the power supply line D, a signal line can also be wired from the power supply control device C to the thin light emitting block 1, and a clock unit including an IC or the like having a clock function is internally provided in the thread line unit 4. It can also have a function of controlling the lighting timing of the delay.

It is also possible to make the adjacent thin light emitting block 1 blink while shifting, and by blinking while shifting, the blinking control is sequentially performed so that the light from the lit light emitting unit 4a moves in the direction in which the train enters. You can also let it.

In the delay lighting control that blinks while shifting in this way, for example, the thin light emitting block 1 shown in FIG. 5 has a synchronized clock unit, and the first thin light emitting block 1 has an IC having a clock function at a light emitting timing of 0 seconds. The adjacent second thin light emitting block 1 has a clock function IC having a light emission timing of 0.25 seconds, and the adjacent third thin light emitting block 1 has a clock function IC having a light emission timing of 0.5 seconds. Then, in the adjacent fourth thin light emitting block 1, the IC having a clock function lights at a light emitting timing of 0.75 seconds for about 200 msec.

By repeating this in a predetermined cycle, for example, in a cycle of 1 second, it is possible to turn on the light from the light emitting unit 4a of the first to fourth thin light emitting blocks 1 so as to move sequentially. When laying a large number of thin light emitting blocks 1, the light emitting timing is finely adjusted, and a plurality of sets of the first to fourth thin light emitting blocks 1 are arranged.
