A balustrade base 30 that holds the glass panel 3 is provided on the lower side of the glass panel 3. The balustrade base 30 is provided on both sides of the step 2 and has a panel-shaped skirt guard 6 continuously provided along the moving direction of the step 2, and a skirt that is provided outside the glass panel 3 and sandwiches the glass panel 3. The exterior member 8 is arranged so as to face the guard 6 and covers the main frame 1. In addition, the balustrade base 30 is provided between the inner deck 7 provided so as to cover between the glass panel 3 and the upper end of the skirt guard 6, and between the outer side of the lower side of the glass panel 3 and the upper end of the exterior member 8. And an outer deck 9 provided so as to cover. Here, as shown in FIG. 2, an inner space K of the balustrade base 30 is defined inside the skirt guard 6, the inner deck 7, the exterior member 8 and the outer deck 9.
In the following description, the width direction of the passenger conveyor 100 is the width direction X, and the direction perpendicular to the outer deck 9, that is, the direction perpendicular to the inclination angle of the passenger conveyor 100 is Y. The width direction X and the vertical direction Y are orthogonal to each other.

As shown in FIG. 2, inside the balustrade base 30, a glass holder 10 that abuts the lower end of the glass panel 3 and supports the glass panel 3 is provided. The glass holder 10 is fixed by bolts 11 so that the height and the width direction can be adjusted. The outer deck 9 is placed and fixed on the glass holder 10, and the lower side portion of the glass panel 3 is placed and held. Usually, the length of the glass holder 10 is about 250 mm, and a plurality of glass holders 10 are attached at a pitch of about 1200 mm in the longitudinal direction of the passenger conveyor 100. When the glass holder 10 is attached to the main frame 1, a piano wire is stretched between the upper and lower ends of the main frame 1, and each glass holder 10 is centered in the height and width directions with respect to the piano wire. Here, each glass holder 10 is aligned in a straight line from the bottom to the top of the inclined portion of the passenger conveyor 100 so that slight bending and distortion of the main frame 1 which is a long object does not affect the performance of the balustrade 40. Are attached so that they are aligned with each other.

Further, a glass retainer 12 is detachably installed on each glass holder 10. As shown in FIGS. 2 and 4, the glass presser 12 has an angled shape with both ends protruding toward the step 2 in the width direction X. Specifically, the glass retainer 12 is provided so as to face the glass panel 3 and extends in the vertical direction Y, and a pair of the retainer 12a provided orthogonal to both ends of the retainer 12a and extending in the width direction X. And a mounting portion 12b. The pressing portion 12a is fixed by sandwiching the lower side portion of the glass panel 3 with the glass holder 10 by screwing the bolt 13. Further, an upper skirt angle 16 having a substantially L-shaped cross section is fixed to the mounting portion 12 b of the glass retainer 12 with a bolt 22. The upper skirt angle 16 is directly installed on the mounting portion 12b of the glass presser 12. Then, the surface of the upper skirt angle 16 on the step 2 side is installed in conformity with the lower skirt angle 15 which is an existing one, and the position of the upper skirt angle 16 in the width direction X can be determined. Further, the upper end portion 6b of the skirt guard 6 is placed on the upper skirt angle 16 and fixed by a flat head screw 23 and a special nut 24. The upper skirt angle 16 is provided in contact with the inner side surface of the skirt guard 6, that is, the side surface facing the internal space K. The mounting position of the special nut 24 can be adjusted in the longitudinal direction of the passenger conveyor 100. As a result, the skirt guard 6 is fixed to the mounting portion 12b of the glass presser 12 via the upper skirt angle 16. A fixing clip 6a is provided on the lower portion of the skirt guard 6 by spot welding. Here, the lower skirt angle 15 having a substantially L-shaped cross section is attached to the main frame 1, and the fixing clip 6a sandwiches the lower skirt angle 15. The skirt guard 6 is arranged with a slight gap 17 secured between it and the step 2.

A clip body 25 is provided on the upper skirt angle 16, and the upper end portion 6b of the skirt guard 6 and the end portion 7a of the inner deck 7 are press-fitted into the clip body 25. Further, the other end portion 7b of the inner deck 7 is fixed to a bracket 26 attached to the pressing portion 12a of the glass pressing member 12 with a pan head screw 27. That is, the inner deck 7 is fixed to the glass retainer 12 via the upper skirt angle 16 and the clip body 25.
Further, the flat head screw 23, the special nut 24, and the pan head screw 27 are provided in the internal space K defined inside the skirt guard 6 and the inner deck 7. Here, the flat head screw 23 and the special nut 24 form a fixing member.

A hard packing 14 is inserted between the glass panel 3 and the outer deck 9. Further, the soft packing 28 is also inserted between the glass panel 3 and the inner deck 7 so as to cover the fixed portion of the pan head screw 27.

A guide rail 20 fixed to the main frame 1 is provided below the glass retainer 12. A resin roller 21 that rolls and moves is arranged on the guide rail 20. The guide rail 20 guides the movement of the resin roller 21, and thereby the movement of the step 2.

When the passenger conveyor 100 is repaired, as shown in FIG. 3, the skirt guard 6, the inner deck 7, the glass retainer 12 and the glass panel 3 are removed and replaced with new ones. The existing members for the exterior member 8, the outer deck 9, the glass holder 10, and the lower skirt angle 15 are used as they are.

As described above, when the passenger conveyor 100 is refurbished, the glass panel 3, the glass retainer 12, the upper skirt angle 16, the skirt guard 6 and the inner deck 7 are removed and replaced with new ones, and the guard rail 5 on the glass panel 3 is replaced. Also replace the moving handrail 4. Therefore, as the exterior member 8, the outer deck 9, the glass holder 10, and the lower skirt angle 15, existing ones are used as they are. Here, the glass holder 10 serves as a mounting base for the design parts of the balustrade 40. Further, the outer deck 9 may be caulked with the adjacent building interior. Further, the lower skirt angle 15 serves as a reference for securing the gap 17 with the step 2. Therefore, the existing ones can be used as they are without exchanging these constituent articles, so that the time required for the repair work can be significantly reduced.
Further, since the existing glass holder 10 is used without being removed from the passenger conveyor 100, it is not necessary to perform a complicated centering operation for the glass holder 10.

Further, in the passenger conveyor 100, the skirt guard 6 and the inner deck 7 are fixed while being placed on the upper skirt angle 16. As a result, the skirt guard 6 and the inner deck 7 are attached to the glass presser 12 whose height dimension has already been adjusted via the upper skirt angle 16, so that position adjustment such as centering work during repair work is performed. Time is reduced.

When the skirt guard 6 and the inner deck 7 are attached to the upper skirt angle 16 from the step 2 side as in the passenger conveyor 200 according to the conventional example shown in FIG. 5, the skirt guard 6 and the inner deck 7 are located at predetermined positions. It is necessary to temporarily place the tape on the upper skirt angle 16 and then fix it to the upper skirt angle 16. In this case, the upper skirt angles 16 must be individually matched and punched and tapped from the large number of flat holes provided in the skirt guard 6 and the inner deck 7. On the other hand, in the passenger conveyor 100 according to this embodiment, by mounting the skirt guard 6 and the inner deck 7 on the upper skirt angle 16, the positions of the skirt guard 6 and the inner deck 7 with respect to the upper skirt angle 16 can be adjusted. It will be easier. Therefore, when fixing the skirt guard 6 and the inner deck 7 to the upper skirt angle 16, it is not necessary to perform flat screw fixing by physical matching as in the conventional passenger conveyor 200.

Further, a fixing member for fixing the skirt guard 6 and the inner deck 7, that is, a flat head screw 23, a special nut 24 and a pan head screw 27 are arranged in the internal space K defined inside the skirt guard 6 and the inner deck 7. As a result, the flat head screws 18 and 19 unlike the passenger conveyor 200 according to the conventional example shown in FIG. 5 are not provided. Therefore, there is no need for on-site transfer drilling work, and there is no risk that cutting chips will fall onto the guide rail 20 and damage the resin roller 21 and the guide rail 20, or worsen the riding comfort. Further, there is no risk that the flat head screws that fix the inner deck 7 will loosen and project to the passenger side, and the safety of the passenger conveyor 100 can be further improved. Further, since a lot of drilling work and tapping work for attaching the flat head screws are unnecessary, it is possible to shorten the time for the repair work.

If the outer deck 9 is found to be damaged by prior field survey, the outer deck 9 may be repaired or partly replaced, or the outer deck 9 may be replaced with a new one. Conceivable. Since the outer deck 9 is simply bolted onto the glass holder 10, it is considered that there will be no significant increase in the repair work time unless there is caulking finish or the like with the adjacent building interior. Be done.
