By attaching the upright piece 14 to the base 10 in this manner, the other side 14B can be raised in a direction perpendicular to the longitudinal outer peripheral surface 12 of the base 10. Leveling screws 16 as levelers for horizontally installing the base 10 in installation holes formed in the platform are attached to both end portions of the other side 14B of the upright piece 14 in the longitudinal direction.

  As shown in FIG. 3, in the internal space 11 of the base 10, a fixing portion 18 for fixing a fixing screw 30 as a fixing means for fixing the message display portion 20 is erected on the inner bottom surface 13. . The fixing screw 30 is preferably a so-called countersunk screw, and more preferably a hexalobular screw type countersunk in terms of preventing tampering. A female screw hole as a fixing hole 18 </ b> A is formed in the fixing portion 18, and is erected at positions near the corners on the inner bottom surface 13 of the base 10. Further, the inner bottom surface 13 has a plurality of through holes 19 formed therein.

  One of the through holes 19 is provided with a connection plug 17 to which a wiring drawn from the message display unit 20 is electrically connected. The connection plug 17 can be connected to a connection connector (not shown) embedded in the bottom of the recess at the installation target location. A wiring for transmitting a proximity signal transmitted from a train proximity sensor (not shown) is electrically connected to the connection connector. Further, rainwater or the like that has entered the internal space 11 of the base 10 can be discharged to the outside of the base 10 through the through hole 19 in which the connection plug 17 is not provided. Depending on the position of the connection connector (not shown), a through hole 19 for disposing the connection plug 17 can be formed in the side surface of the base 10.

  The message display unit 20 is formed in a rectangular parallelepiped shape that can be accommodated in the internal space 11 of the base 10. The message display part 20 is assembled so that a case part 21 formed in a box shape with an upper surface opening and a lid part 22 covering the upper surface of the case part 21 can be disassembled by screwing. The lid 22 has a frame member 22A and a laminated glass 22B, and the laminated glass 22B is formed in a larger size in the lower glass 22B2 than in the upper glass 22B1.

  The upper glass 22B1 is accommodated on the inner peripheral surface of the frame body 22A in a state of being overlaid on the lower glass 22B2. A caulking 50 is filled between the upper glass 22B1 and the frame 22A. The lower glass 22B2 is placed on the receiving portion 21A formed inside the case portion 21 via the packing 23, and the caulking 50 is filled with the inner peripheral surface of the case portion 21. Thus, the frame member 22A is screwed to the case portion 21 using an assembly screw 26. The assembly screw 26 is preferably a screw that is attached and detached using a hexagon wrench. The height position of the upper surface of the lid portion 22 is adjusted so that the height of the upper surface of the base 10 is the same as the height of the floor surface of the platform.

  Further, a message display body 24 as shown in FIG. 4 is accommodated in the internal space of the case portion 21. In the present embodiment, the message display body 24 includes a plurality of display bodies 24B arranged in a matrix in which LEDs 24A whose blinking state is switched by an LED blinking control unit (not shown) are arranged on the upper surface of the substrate 24C with a required interval S therebetween.

The round can bolt 40 can be screwed into the mounting hole 32 of the frame member 22A, but the round can bolt to the mounting hole 32 is not screwed into the female screw portion as the fixing hole 18A having a diameter smaller than the diameter of the round can bolt 40. The amount of insertion of 40 is also regulated. Therefore, when the message display unit 20 is taken out from the base 10 (lifted), the round can bolt 40 is inserted into the mounting hole 32 as much as possible (screwed as much as possible), and then the round can bolt 40 is pulled up. As shown in FIG. 6, the message display unit 20 can be taken out while being separated from the base 10.

  In particular, the gap between the base 10 and the message display unit 20 is filled with a coking 50 for the purpose of waterproofing. In addition to this, if the message display unit 20 is fixed to the base 10 due to long-term use, the message display unit 20 may not be lifted from the base 10 in some cases. In this regard, according to the relationship between the diameters of the mounting hole 32 and the fixing hole 18A as described above, the circular can bolt 40 is uniformly inserted into the mounting hole 32 even after the tip of the round can bolt 40 contacts the upper end of the fixing portion 18. This is advantageous in that it has an effect of lifting the message display unit 20 from the base 10 along the round cam bolt 40. In such a use form, it is preferable that the round can bolt 40 is screwed into all the mounting holes 32, but the round can bolt 40 is attached only to the two mounting holes 32 at diagonal positions on the upper surface of the message display unit 20. The same effect can be obtained even when it is mounted.

  Thus, since the message display part 20 can be made into the state isolate | separated from the base 10, the base 10 arrange | positioned in the appropriate state in the installation object location of a platform can be left as it is. As a result, the message display unit 20 after maintenance or replacement can be installed in an appropriate state with respect to the floor of the platform simply by re-fixing to the base 10, so that the message display unit 20 can be exchanged extremely. This is advantageous in that it can be performed in a short time. The message display unit 20 and various wirings embedded in the platform need only be inserted the connection plug 17 into the connection connector.
