Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the passenger conveyor 100 has the main frame 1 constructed between the upper floor building beam and the lower floor building beam. The main frame 1 supports the weight of the passenger conveyor 100 itself and the weight of the passenger from below. The passenger conveyor 100 is connected endlessly and circulates between the upper floor and the lower floor in an obliquely upward direction or an obliquely downward direction, and a balustrade part 40 provided on both sides of the step 2 Have The balustrade section 40 includes a glass panel 3 and a moving handrail 4 that is supported by the glass panel 3 and circulates in synchronization with the steps 2. A guard rail 5 that engages the moving handrail 4 and guides the moving handrail 4 is provided on the top of the glass panel 3.

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 located on both sides of the step 2 and is continuously provided along the moving direction of the step 2, and the skirt guard 6 provided outside the glass panel 3 and sandwiching the glass panel 3 with the skirt And an exterior member 8 that is arranged to face the guard 6 and covers the main frame 1. 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 defined as 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 defined as Y. The width direction X and the vertical direction Y are orthogonal to each other.

  As shown in FIG. 2, a glass holder 10 that contacts the lower end of the glass panel 3 and supports the glass panel 3 is provided inside the balustrade base 30. The glass holder 10 is fixed by a bolt 11 so that the height and the width direction can be adjusted. Further, 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 in the longitudinal direction of the passenger conveyor 100 at a pitch of about 1200 mm. 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 reference to the piano line. Here, each glass holder 10 is 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 quality of the balustrade part 40. To be aligned.

  A glass presser 12 is detachably installed on each glass holder 10. As shown in FIGS. 2 and 4, the glass presser 12 has an angle shape in which both end portions protrude to the step 2 side in the width direction X. Specifically, the glass presser 12 is provided so as to face the glass panel 3 and extend in the vertical direction Y, and a pair of pressers 12a extending in the width direction X orthogonal to both ends of the presser 12a. And a mounting portion 12b. The holding part 12a is fixed by sandwiching the lower side part of the glass panel 3 with the glass holder 10 by screwing the bolts 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 presser 12 by a bolt 22. The upper skirt angle 16 is installed as it is on the mounting portion 12 b of the glass presser 12. Then, the position of the upper skirt angle 16 in the width direction X can be determined by setting the surface of the upper skirt angle 16 on the step 2 side so as to match the lower skirt angle 15 that uses the existing one as it is. Further, the upper end portion 6 b of the skirt guard 6 is placed on the upper skirt angle 16 and is fixed by a countersunk 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 inner space K. In addition, the special nut 24 can adjust an attachment position in the longitudinal direction of the passenger conveyor 100. Thereby, the skirt guard 6 is fixed to the mounting portion 12 b of the glass presser 12 via the upper skirt angle 16. A fixing clip 6a is provided at the lower part of the skirt guard 6 by spot welding. Here, a lower skirt angle 15 having a substantially L-shaped cross section is attached to the main frame 1, and the fixing clip 6 a sandwiches the lower skirt angle 15. The skirt guard 6 is arranged in a state where a slight gap 17 is secured between the skirt guard 6 and the step 2.

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

  A guide rail 20 fixed to the main frame 1 is provided below the glass presser 12. A resin roller 21 that rolls and moves is disposed on the guide rail 20. The movement of the resin roller 21 is guided by the guide rail 20, whereby the movement of the step 2 is also guided.

  When repairing the passenger conveyor 100, 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. Further, the exterior members 8, the outer deck 9, the glass holder 10, and the lower skirt angle 15 are assumed to be used as they are.

As described above, when the passenger conveyor 100 is repaired, 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. The moving handrail 4 is also exchanged. Accordingly, the exterior members 8, the outer deck 9, the glass holder 10, and the lower skirt angle 15 are used as they are. Here, the glass holder 10 serves as a mounting base for design parts of the balustrade section 40. Further, there is a possibility that caulking or the like is performed between the outer deck 9 and the adjacent architectural interior. Further, the lower skirt angle 15 is a reference for securing a gap 17 with the step 2. Therefore, since the existing ones can be used as they are without exchanging these components, the time required for the repair work can be greatly reduced.
Further, since the existing glass holder 10 is used without removing it from the passenger conveyor 100, it is not necessary to perform a complicated centering operation for the glass holder 10.

  In the passenger conveyor 100, the skirt guard 6 and the inner deck 7 are fixed in a state of 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 has already been adjusted via the upper skirt angle 16, so that it is necessary to adjust the position of the centering work during the repair work. Time is shortened.

  Further, 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 placed at predetermined positions. It is necessary to secure the upper skirt angle 16 by using a flat head screw after temporarily placing it on the skirt. In this case, the skirt guard 6 and the inner deck 7 must be aligned with the upper skirt angle 16 one by one from a large number of flat holes and drilled and tapped. On the other hand, in the passenger conveyor 100 according to this embodiment, the skirt guard 6 and the inner deck 7 are placed on the upper skirt angle 16 to adjust the positions of the skirt guard 6 and the inner deck 7 with respect to the upper skirt angle 16. It becomes easy. Therefore, when the skirt guard 6 and the inner deck 7 are fixed to the upper skirt angle 16, it is not necessary to perform the flat screw fixing by the actual matching as in the conventional passenger conveyor 200.

  Further, fixing members 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 an internal space K defined inside the skirt guard 6 and the inner deck 7. Thereby, there are no flat screws 18 and 19 like the passenger conveyor 200 according to the conventional example shown in FIG. Accordingly, there is no transfer hole drilling work on site, and there is no possibility that the chips fall on the guide rail 20 to damage the resin roller 21 or the guide rail 20 or deteriorate the riding comfort. Moreover, the flat screw which fixes the inner deck 7 is loosened, and there is no possibility of protruding to the passenger side, and the safety of the passenger conveyor 100 can be further improved. In addition, since a large number of drilling operations and tapping operations for attaching a flat head screw are not required, the time required for repair work can be shortened.

  In addition, if it is determined that the outer deck 9 is damaged by a prior field survey, the outer deck 9 may be repaired or partially replaced, or the outer deck 9 set 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 refurbishment time unless there is a caulking finish between adjacent building interiors. It is done.

  2 steps, 3 glass panel, 4 moving handrail, 6 skirt guard, 7 inner deck, 9 outer deck, 10 glass holder, 12 glass retainer, 16 upper skirt angle, 23 countersunk screw (fixing member), 24 special nut (fixing member) ), 100 passenger conveyor, K interior space.
