Furthermore, a predetermined gap is formed between the upper end of the upper insertion portion 23b and the lower end of the clip body 35A.

Further, as shown in FIG. 3, the gap closing plate 24 is fixed to the back surface of the cover body 23 so as to extend from one side edge of the cover body 23 in the moving direction of the step 3 in the moving direction of the step 3. Has been. At this time, the gap closing plate 24 has a size from the upper insertion portion 23b to the lower insertion portion 23c. The gap closing plate 24 is fitted in the fitting recess 31 a of the cover position fixing plate 31.
Each gap closing plate 24 of the illumination cover 22 is fitted into each fitting recess 31 a of the cover position fixing plate 31, and the illumination cover 22 is arranged in the moving direction of the steps 3. That is, the position of each lighting cover 22 in the moving direction of the step 3 is determined by the arrangement position of the cover position fixing plate 31. At this time, a predetermined gap 34 is formed between adjacent cover main bodies 23.

  Further, in the adjacent cover main body 23, the part of the gap closing plate 24 that extends from one side edge in the moving direction of the step 3 in one cover main body 23 is in the moving direction of the step 3 in the other cover main body 23. It is covered on the other edge side. That is, the gap closing plate 24 is disposed across the back surfaces of the adjacent cover main bodies 23, and the gap 34 between the adjacent cover main bodies 23 is covered with the gap closing plate 24. At this time, the surfaces of the intermediate portion 23a of the cover main body 23, the skirt guard unit 5 and the side wall portion 11b of the inner deck unit 11 are substantially flush.

  And the light emitted from the lamp | ramp 37 of the skirt illuminating device 21 comprised in this way illuminates the step 3 through the illumination cover 22 which covers the irradiation opening 16. FIG. Moreover, the light which permeate | transmitted the illumination cover 22 turns into light light gentle to a passenger's eyes.

  Next, advantages obtained by disposing the predetermined gap 34 between the cover main bodies 23 of the adjacent illumination covers 22 and closing the predetermined gap 34 with the gap closing plate 24 will be described.

The predetermined gap 34 is determined in consideration of the length in the moving direction of the step 3 in the cover main body 23 of the illumination cover 22, the magnitude of the surrounding temperature change, and the linear expansion coefficient of the cover main body 23.
For example, when methacrylic resin is used as the material of the lighting cover 22, the coefficient of linear expansion is 7 × 10 ⁻⁵ [1 / deg]. Further, it is assumed that the length of the cover 3 in the moving direction of the step 3 is 1000 [mm] and the maximum change in the ambient temperature is 40 [deg]. At this time, the maximum expansion / contraction amount of the cover main body 23 due to thermal contraction or thermal expansion is about 1000 × 40 × 7 × 10 ⁻⁵ ≈about 3 mm. The adjacent illumination covers 22 are arranged with a predetermined gap 34 between the cover main bodies 23 larger than the maximum expansion / contraction amount of each cover main body 23.

  Here, when the ambient temperature of the cover main body 23 rises, each of the lighting covers 22 is thermally expanded. If the cover main body 23 is thermally expanded after being arranged without a gap, the end surfaces of the adjacent cover main bodies 23 are brought into close contact with each other in a pressed state, causing a problem that the illumination cover 22 cannot be removed. Further, when the ambient temperature of the cover main body 23 is lowered, the lighting cover 22 is thermally contracted. If the cover bodies 23 adjacent to each other are thermally contracted after being arranged without a gap, a gap is generated between the adjacent cover bodies 23. At this time, when the gap closing plate 24 is not attached to the cover main body, the light of the lamp 37 is directly irradiated to the passenger from the gap, which causes a problem that the passenger who feels dazzling feels uncomfortable. Further, there arises a problem that dust enters the skirt guard 4 through a gap between the adjacent cover main bodies 23.

  However, in the present embodiment, since the predetermined gap 34 is provided between the cover main bodies 23 of the adjacent illumination covers 22, it is possible to prevent the illumination cover 22 from being removed. Moreover, since the gap closing plate 24 is disposed in the cover main body 23 so as to close the predetermined gap 34 between the adjacent cover main bodies 23, the light from the lamp 37 cannot leak directly to the step 3. To be prevented. That is, it is possible to prevent the passenger from being uncomfortable with the light of the lamp 37 being directly irradiated to the passenger. Further, it is possible to prevent dust from entering the skirt guard 4 beforehand.

  The gap closing plate 24 also thermally contracts and expands due to a change in ambient temperature, but the length in the step 3 direction is short and the amount of contraction and expansion of the gap closing plate 24 is small. It suffices that the gap between the closing plate 24 is slightly open. Therefore, even if a force is applied in the moving direction of the step 3 of the lighting cover 22, the lighting cover 22 is hardly moved in the moving direction of the step 3.

Next, a method for attaching / detaching the skirt guard 4, the lighting cover 22, and the inner deck 10 will be described.
First, a method for attaching and detaching the skirt guard 4 will be described with reference to FIG.
The skirt guard 4 is attached / detached in a state in which the configuration of the skirt lighting device 21 such as the lighting case 28 and the lamp 37 excluding the lighting cover 22 is disposed in advance, and the inner deck 10 is removed.

  When attaching the skirt guard 4, first, each of the skirt guards 5 is arranged so that the first stud bolt 5a protrudes opposite to the step 3 side. Then, the first stud bolt 5a is inserted into the slit hole formed in the skirt guard support 26 and the plate member 27, and the lower edge portion side of the skirt guard unit 5 is fixed to the main frame 2 (not shown). . Further, the first nut 15 a is tightened from the tip of the first stud bolt 5 a, and the upper edge side of the skirt guard unit 5 is supported by the skirt guard support body 26. The first nut 15a can be easily tightened by inserting the spanner 41 into the opening 29d.

  When the skirt guard 4 is removed, the fixing of the main frame 2 and the lower edge side of each skirt guard 5 is released in advance. Furthermore, the spanner 41 is put in the open part 29d, and the first nut 15a is loosened. Since the first stud bolts 5a are inserted into the split holes opened at the upper edges of the skirt guard support 26 and the plate-like member 27, the skirt guards 5 are pulled out upward in sequence. The guard 4 can be removed.

  Stored inside the skirt guard 4 are a handrail guide with frequent maintenance and inspection, a driving device (not shown) for moving the moving handrail 9, and the like. As described above, the first stud bolt 5a protruding from the back surface of the skirt guard unit 5 is inserted into the standing portion 26b of the skirt guard support 26 and the split hole of the plate member 27. Each of the single units 5 can be attached and detached without removing the configuration of the skirt illumination device 21 other than the illumination cover 22. Therefore, it is possible to easily perform maintenance and inspection of devices and parts arranged inside the skirt guard 4 such as a handrail guide and a driving device for moving the moving handrail 9.

Next, the attachment / detachment of the illumination cover 22 will be described with reference to FIG.
First, a method for attaching the illumination cover 22 will be described.
Before the lighting cover 22 is attached, the other configurations of the skirt lighting device 21 such as the lighting case 28 and the lamp 37 described above are arranged in advance.

  Then, the cover main body 23 is arranged in a direction in which the lower insertion portion 23 c faces downward and the convex side is exposed to the irradiation port 16. Then, the gap closing plate 24 attached to the back surface of the cover main body 23 is inserted into the fitting recess 31 a from above and slid downward, and the lower insertion portion 23 c is inserted into the lower insertion space portion 32. At this time, the cover position fixing plate 31 is fixed in advance to the upper side 29b with screws 39 so that the adjacent illumination covers 22 are disposed with a predetermined gap 34 therebetween. Even after the cover main body 23 is disposed, the cover position fixing plate 31 and the cover main body 23 can be moved in the major axis direction of the insertion hole 31b formed in an ellipse by loosening the screw 39. That is, the predetermined gap 34 can be adjusted even after the cover body 23 is disposed.

Then, the lighting cover 22 is sequentially installed with a predetermined gap 34 between the adjacent cover main bodies 23 so as to be continuous from the entrance side to the exit side, whereby the installation of the illumination cover 22 is completed.
The illumination cover 22 can be easily removed by simply pulling it upward when the inner deck 10 is not disposed.

Next, the removal of the inner deck 10 will be described with reference to FIG.
The inner deck 10 is attached and detached with the illumination cover 22 attached.
First, when the inner deck 10 is attached, the edge portion of the top plate portion 11a of the inner deck unit 11 is aligned with the inner deck support member 12, and the insertion groove portion 35a of the clip body 35A attached to the side wall portion 11b and the illumination case 28 are mounted. The inner deck unit 11 is pushed downward so that the mounting portion 30 is fitted. The inner decks 11 are sequentially attached so as to be continuous from the entrance side to the exit side. Furthermore, the edge of the inner deck unit 11 opposite to the side wall portion 11b is fixed to the inner deck support member 12 with the screws 17, whereby the mounting of the inner deck 10 is completed.

  To remove the inner deck 10, first, the screws 17 screwed into the respective inner deck units 11 are removed. And the one end side of the rectangular parallelepiped resin block 42 is applied to the lower edge part of the side wall part 11b from the downward direction according to the inclination part 23d of the cover main body 23. FIG. Furthermore, the insertion state between the insertion groove portion 35a of the clip body 35A and the attachment portion 30 can be released by hitting the other end of the resin block 42 from below with a hammer 43 or the like. That is, the inner deck unit 11 can be removed. All the inner decks 11 are similarly removed, and the removal of the inner deck 10 is completed.

  Thus, since the upper edge of the inclined part 23d of the cover body 23 is disposed in the vicinity of the lower edge part of the side wall part 11b, the attachment part 30 is closely inserted into the insertion groove part 35a of the clip body 35A. Even when it is difficult to come off, the inner deck 10 can be easily removed using the resin block 42 and the hammer 43. In addition, the inclined portion 23d of the illumination cover 22 is exposed to the step 3 side and is inclined downward from the upper insertion portion 23b toward the intermediate portion 23a, and therefore, between the upper insertion portion 23b and the intermediate portion 23a.
