[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic diagram showing the configuration of an escalator according to embodiment 1. In the figure, a truss 11 is installed between an upper floor and a lower floor of a building.

[0010] A plurality of steps 12 are supported on the truss 11. The plurality of steps 12 are connected together in an endless manner. In FIG. 1, only four of the plurality of steps 12 are shown.

[0011] The multiple steps 12 circulate along a travel route. The travel route includes an outbound route and a return route. The outbound route is a section where each step 12 picks up and transports passengers. The return route is a section where each step 12 returns from the end point of the outbound route to the start point of the outbound route.

[0012] A pair of balustrades 13 are erected on the truss 11. An endless moving handrail 14 is provided on each balustrade 13. Each moving handrail 14 circulates in synchronization with the movement of the multiple steps 12.

[0013] Fig. 2 is a perspective view showing the vicinity of the entrance / exit point of the escalator in Fig. 1. Each balustrade 13 has balustrade glass 15, a deck board 16, a skirt guard 17, a plurality of balustrade posts (not shown), and a handrail guide rail (not shown).

[0014] The balustrade glass 15 is supported by a plurality of balustrade posts. The plurality of balustrade posts are erected on the truss 11 at intervals in the direction of movement of the step 12. The handrail guide rail is fixed to the balustrade glass 15 and guides the movement of the moving handrail 14.

[0015] The deck board 16 is arranged continuously at the lower end of the balustrade glass 15 from the upper entrance to the lower entrance.

[0016] The skirt guard 17 is disposed continuously from the upper entrance to the lower entrance on the step 12 side of the deck board 16. The skirt guard 17 faces the side of each step 12 on the outward path.

[0017] The skirt guard 17 is constructed by joining multiple skirt guard segments together along the forward path. Each skirt guard segment is made of, for example, hot-dip galvanized steel sheet. A gap is maintained between the skirt guard 17 and the side of the step 12.

[0018] Figure 3 is a perspective view showing a portion of the escalator in Figure 2. A pair of drive rails 18 and a pair of follower rails (not shown) are provided on the truss 11. A plurality of steps 12 circulate while being guided by the pair of drive rails 18 and the pair of follower rails.

[0019] Each drive rail 18 has an outgoing portion 18a and a returning portion 18b. Of the outgoing portions 18a of the pair of drive rails 18, only one outgoing portion 18a is shown in Figure 3.

[0020] The steps 12 are connected to each other via a pair of endless step chains 19. In FIG. 3, only one of the pair of step chains 19 is shown. is shown.

[0021] Each step chain 19 is provided with a plurality of chain rollers 20 and a plurality of drive rollers 21. When the plurality of steps 12 circulates, each chain roller 20 and each drive roller 21 moves while being guided by the corresponding drive rail 18. Each drive roller 21 is connected to the corresponding step 12.

[0022] Each step 12 has a frame 22, a tread 23, a riser 24, a step shaft 25, and a pair of follower rollers 26. In Fig. 3, only one follower roller 26 of the pair of follower rollers 26 is shown.

[0023] The step 23 is provided on the upper part of the frame 22 when the step 12 is positioned in the forward direction. The step 23 also serves as a platform for passengers to board when the step 12 moves in the forward direction. The riser 24 is provided on the lower end of the frame 22.

[0024] The step shaft 25 is provided on the frame 22 along the width direction of the step 12. The width direction of the step 12 is perpendicular to the vertical direction and perpendicular to the direction in which the step 12 moves.

[0025] A driving roller 21 is rotatably attached to each end of the step shaft 25. As a result, the step shaft 25 is connected to a pair of step chains 19.

[0026] The guide auxiliary device 30 has a plurality of step-side magnet bodies 31 and a plurality of balustrade-side permanent magnets 32. The guide auxiliary device 30 also suppresses displacement of the step 12 in the width direction of the step 12, and prevents the step 12 from contacting the skirt guard 17.

[0027] A plurality of step-side magnet bodies 31 are provided on the guided steps. The guided step is at least one of the plurality of steps 12. In the first embodiment, all of the steps 12 are guided steps. A pair of left and right step-side magnet bodies 31 are provided on each step 12. Each step-side magnet body 31 faces the skirt guard 17. Each step-side magnet body 31 generates a magnetic force toward the skirt guard 17.

[0028] Each balustrade-side permanent magnet 32 is provided on a corresponding skirt guard 17. Although only some of the skirt guards 17 are shown in Figure 3, multiple balustrade-side permanent magnets 32 are provided continuously along the movement trajectory of the step-side magnetic body 31 on the outward path.

[0029] Each balustrade-side permanent magnet 32 generates a repulsive force against the step-side magnetic body 31. That is, each step-side magnetic body 31 and each balustrade-side permanent magnet 32 are installed so that the same poles face each other. The steps 12 receive repulsive forces of equal strength from both sides in the width direction of the steps 12, thereby preventing each step 12 from coming into contact with the pair of left and right skirt guards 17.

[0030] In addition, each balustrade-side permanent magnet 32 is fixed to the surface of the skirt guard 17 opposite to the surface facing the side of each step 12, i.e., to the back surface of the skirt guard 17 when viewed from above the step 12.

[0031] 4 is a side view of the step 12 as viewed along the arrow IV in FIG. 3. A holder 27 is provided on the frame 22 of each step 12. A step shaft 25 passes through the pair of holders 27. The pair of holders 27 sandwich and hold the step shaft 25. Each step-side magnetic body 31 is attached to the holder 27 on the guided step.

[0032] Fig. 5 is a cross-sectional view of the step-side magnetic body 31 of Fig. 4. The step-side magnetic body 31 has a guide pad 33 made of resin and a step-side permanent magnet .

[0033] The step-side permanent magnets 34 are insert-molded into the guide pads 33. Neodymium magnets are used as the step-side permanent magnets 34 and the balustrade-side permanent magnets 32.

[0034] The guide pad 33 has a pad body 33a and a protrusion 33b. The pad body 33a covers the entire step-side permanent magnet 34. The protrusion 33b protrudes from the pad body 33a.

[0035] Fig. 6 is a perspective view showing holder 27 of Fig. 4. Holder 27 has a base portion 27a and a magnetic body mounting portion 27b. Base portion 27a is a portion of holder 27 that holds step shaft 25. Step-side magnetic body 31 is mounted in magnetic body mounting portion 27b by fitting protrusion 33b into magnetic body mounting portion 27b.

[0036] 7 is a plan view showing the step 12 of FIG. 4. Each step-side magnetic body 31 protrudes from the end face of the step 12 in the width direction. In FIG. 7, the protrusion amount of each step-side magnetic body 31 from the step 12 is shown as being large, but the actual protrusion amount is small. As a result, the width dimension W1 of the step 12 including the left and right step-side magnetic bodies 31 is larger than the width dimension W0 of the step 12 excluding the left and right step-side magnetic bodies 31.

[0037] In this passenger conveyor, each step 12 is provided with a step-side magnet body 31, and each skirt guard 17 is provided with a plurality of balustrade-side permanent magnets 32. This prevents each step 12 from coming into contact with each skirt guard 17. This prevents the generation of abnormal noise and damage to each skirt guard 17.

[0038] Furthermore, wear on the guide parts that guide the movement of each step 12 can be suppressed, reducing the frequency of replacement of the guide parts and improving maintainability.

[0039] Furthermore, in each step-side magnet body 31, the step-side permanent magnet 34 is insert-molded into the resin guide pad 33. Therefore, even if the step 12 is subjected to a force greater than expected and swings significantly in the width direction, the resin guide pad 33 will come into contact with the skirt guard 17. This makes it possible to more reliably prevent damage to parts due to contact between the step 12 and the skirt guard 17.

[0040] Furthermore, each balustrade-side permanent magnet 32 is provided on the surface of the skirt guard 17 opposite to the surface facing the side of each step 12. This prevents the gap between each step 12 and the skirt guard 17 from increasing, and also prevents a deterioration in the design.

[0041] Furthermore, each step-side magnet body 31 is attached to a holder 27 on the corresponding step 12. This allows each step-side magnet body 31 to be easily attached to the corresponding step 12. Furthermore, the step-side magnet body 31 can be easily attached to an existing step 12.

[0042] Further, the guide pad 33 is provided with a protrusion 33b. Further, the holder 27 is provided with a magnetic body mounting portion 27b. The step-side magnetic body 31 is mounted to the holder 27 by fitting the protrusion 33b into the magnetic body mounting portion 27b. This makes it easier to attach the step-side magnetic body 31 to an existing step 12.

[0043] The balustrade-side permanent magnets 32 may be provided continuously or intermittently along the movement trajectory of the step-side magnet body 31 on the outward journey. When the balustrade-side permanent magnets 32 are provided intermittently, it is desirable to provide a balustrade-side permanent magnet 32 at a pair of fastening portions located at both ends of each skirt guard segment and at the intermediate portion of each skirt guard segment. This is because the pair of fastening portions and the intermediate portion of each skirt guard segment tend to protrude toward the step 12 and are often close to the side of the step 12.

[0044] Furthermore, all steps 12 do not necessarily have to be guided steps; for example, guided steps and steps not provided with step-side magnetic bodies 31 may be arranged alternately.

[0045] Furthermore, in the first embodiment, an escalator is shown as the passenger conveyor, but the passenger conveyor may be a moving walkway. [Explanation of symbols]
