DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. Here, parts that are the same as or equivalent to those of the prior art are denoted by the same reference numerals, and detailed description thereof is omitted.
As in the example shown in FIG. 7, the movable home gate device 10 according to the embodiment of the present invention shown in FIG. 1 has a pedestal portion 14 a of the fence 14 that receives the load of the movable home gate device 10. It is fixed to the base member 20 installed on the floor 12b of the platform 12 via an insulating member 28.
In addition, as shown in FIGS. 2 and 3, the insulating member 28 has an outer shape that protrudes outward from the outer edge portions of the pedestal portion 14 a and the base member 20 in plan view. .

And according to embodiment of this invention, between the base part 14a of the fence 14 of the movable home gate apparatus 10, and the base member 20 installed in the floor part 12b of the platform 12, the insulating member 28 is provided. By interposing, the movable home gate device 10 and the platform 12 can be electrically insulated.
In addition, since the insulating member 28 has an outer shape that protrudes outward from any outer edge portion of the pedestal portion 14a and the base member 20 in plan view, the outer edge portion of the insulating member 28 adheres to the dust 26. It functions as a soot to prevent deposition. Therefore, as shown in FIG. 4, the base portion 14 a and the base member 20 installed on the floor portion 12 b of the platform 12 are in electrical contact via the dust 26 by the outer edge portion 28 a of the insulating member 28. Thus, the adhesion and accumulation of dust 26 around the insulating member can be avoided.

In addition, if dust 26 adheres and the amount of accumulation increases, the base 14a and the base member 20 installed on the floor 12b of the platform 12 may be in electrical contact via the dust 26. However, it takes a long time to reach that state. For this reason, before falling into such itself, the opportunity that dust 26 is removed by cleaning will increase. Moreover, the chance that the dust 26 is naturally removed by the wind due to the passage of the train or the like increases.
Therefore, according to the embodiment of the present invention, the dust 26 adheres to and accumulates on the platform 12 to prevent the movable home gate device 10 and the platform 12 from being in a conductive state as much as possible. It becomes possible to ensure insulation more reliably.

In the example shown in FIGS. 1 to 4, the insulating member 28 is an insulating resin plate that is rectangular in plan view and has a certain thickness. However, it is also possible to use a deformed insulating member 28 as illustrated in FIG.
The application examples shown in FIGS. 5A to 5E show an example in which one of the end portion or the intermediate portion in the thickness direction of the insulating member 28 has a shape protruding outward with respect to the other. It is a thing.

FIG. 5B shows the outer edge portion 28a of the insulating member 28 formed in a step shape in which the upper half of the thickness direction protrudes outward from the lower end portion. FIG. 5C shows a case where the lower half is chamfered so that the upper half of the outer edge portion 28a of the insulating member 28 protrudes outward from the lower half. FIG. 5D shows a rectangular round shape so that the intermediate portion in the thickness direction of the outer edge portion 28a of the insulating member 28 protrudes outward from the upper and lower end portions. FIG. 5E shows a case where the chamfered shape is provided vertically so that an intermediate portion in the thickness direction of the outer edge portion 28a of the insulating member 28 protrudes outward from the upper and lower end portions.
By forming the outer edge portion 28a of the insulating member 28 as in these application examples, it becomes difficult for dust to adhere to and accumulate on the outer edge portion 28a of the insulating member 28, or dust attached to and accumulated on the outer edge portion 28a. It can be easily removed by wind or the like.

Moreover, the application example of FIG.5 (f)-(h) has the shape where the outer edge part 28a of the insulating member 28 covers the outer edge part of the base part 14a and the base member 20, or both. Specifically, in FIG. 5F, the outer edge portion 28 a of the insulating member 28 is bent in an L shape toward the lower side so as to cover the outer edge portion of the base member 20. In FIG. 5G, the outer edge portion 28a of the insulating member 28 is bent in an L shape toward the upper side so as to cover the outer edge portion of the pedestal portion 14a. In FIG. 5H, the outer edge portion 28a of the insulating member 28 is bent in a T shape upward and downward so as to cover the outer edge portion of the base portion 14a and the base member 20.
Further, by forming the outer edge portion 28a of the insulating member 28 as in these application examples, even if dust 26 adheres to and accumulates on the outer edge portion 28a of the insulating member 28, the base portion 14a and the base portion 20 material are formed. It is possible to reliably avoid electrical contact through the dust 26 by the outer edge portion 28 a of the insulating member 28.

In addition, the part which has the external shape which protrudes outside the outer edge part of any of the base part 14a and the base member 20 of the insulating member 28 is supposed to be provided in the part where adhesion and accumulation of dust 26 are assumed. It ’s fine. Further, if necessary, the insulating member 28 may be provided so as to cover a part or the entire periphery of the outer edge portion in a plan view.
Further, the protrusion amount of the outer edge portion 28a of the insulating member 28 with respect to the outer edge portions of the pedestal portion 14a and the base member 20 takes into consideration the degree of adhesion and accumulation of dust 26 and the fact that the protruding portion does not become an obstacle. It is determined as appropriate.

  In addition, as described above, at least a part of the insulating member 28 has not only a form having an outer shape protruding outside the outer edge portions of the pedestal portion 14a and the base member 20 in plan view, but also the insulating member. 28 may have an outer shape that fits inside the outer edge portion of any of the pedestal portion 14a and the base member 20 in plan view. In this case, a groove corresponding to the thickness of the insulating member 28 is formed between the base portion 14a and the outer edge portion of the base member 20, and this groove exhibits a function of preventing loss of insulation.

In other words, the insulating member 28 according to the present invention is a mode in which the outer edge portion forms a step regardless of whether the outer edge portion of the base portion 14a and the base member 20 protrudes or is immersed. By being formed, the shape continuity of the surfaces constituting the pedestal portion 14 a and the outer edge portion of the base member 20 is divided by the insulating member 28. At locations (ridges or grooves) divided in shape by the insulating member 28, the continuity of the dust 26 adhering to and accumulating on the outer edge portions of the pedestal portion 14a and the base member 20 is cut off, and the pedestal portion 14a and the platform 12 are separated. To prevent the occurrence of a situation in which the base member 20 installed on the floor portion 12b is in electrical contact via the dust 26, or to ensure time allowance to reach such a state. Is possible.
