[0009] Embodiment 1 A passenger conveyor according to Embodiment 1 will be described. Fig. 1 is a side view schematically showing the configuration of the passenger conveyor according to this embodiment. In this embodiment, an escalator 100 is exemplified as the passenger conveyor.

[0010] As shown in Figure 1, the escalator 100 has a truss 11 installed between an upper floor and a lower floor. A plurality of steps 12 are supported on the truss 11. A pair of endless step chains 13 are arranged on both sides of the steps 12 in the width direction. The steps 12 are endlessly connected by the pair of step chains 13.

[0011] At the end of the truss 11 on the upper floor side, there are provided a drive unit 14, a pair of upper sprockets 15, a drive chain 16, a brake 17, and a brake unit 18 for use in case of breakage of the drive chain. The drive unit 14 has a motor that drives the escalator 100. The pair of upper sprockets 15 are configured to rotate by the driving force of the drive unit 14. The drive chain 16 is configured to transmit the driving force of the drive unit 14 to the upper sprockets 15.

[0012] The brake device 17 is configured to brake the drive device 14. The drive chain break brake device 18 is configured to prevent rotation of the upper sprocket 15 when the drive chain 16 breaks.

[0013] A pair of lower sprockets 19 are provided at the end of the truss 11 on the lower floor side. Step chains 13 are wound between the pair of upper sprockets 15 and the pair of lower sprockets 19, respectively.

[0014] A pair of balustrades 20 are provided above the truss 11, facing each other with a plurality of steps 12 in between. A pair of endless handrails 22 that move together with the plurality of steps 12 are provided on the peripheries of the pair of balustrades 20, respectively.

[0015] The driving force of the driving device 14 is transmitted to the plurality of steps 12 via the upper sprocket 15 and the step chain 13. The plurality of steps 12 move in a circular manner by the driving force of the driving device 14.

[0016] The movement path of the multiple steps 12 includes an outbound path, an upper floor reversing section, a return path, and a lower floor reversing section. The outbound path is a path along which passengers are transported using the steps 12. The return path is a path along which the steps 12 move in the opposite direction to the outbound path. The upper floor reversing section is located between one end of the outbound path and one end of the return path. The lower floor reversing section is located between the other end of the outbound path and the other end of the return path. The movement direction of the steps 12 reverses at each of the upper floor reversing section and the lower floor reversing section. Boarding and alighting entrances are provided at both ends of the movement path of the steps 12, specifically at both ends of the outbound path.

[0017] 2 is a plan view showing the configuration of the upper floor entrance of the passenger conveyor according to this embodiment. The up-down direction in FIG. 2 represents the movement direction of the step 12. The left-right direction in FIG. 2 represents the width direction of the step 12.

[0018] As shown in Figure 2, a boarding / alighting platform 30 is fixedly provided at the boarding / alighting entrance. The boarding / alighting platform 30 is disposed generally horizontally. A comb plate 40 is provided at the end of the boarding / alighting platform 30 on the step 12 side. The boarding / alighting entrance on the lower floor side has the same configuration as the boarding / alighting entrance on the upper floor side.

[0019] Fig. 3 is an enlarged plan view showing a part of the comb plate and steps in the passenger conveyor according to this embodiment. The up-down direction in Fig. 3 represents the movement direction of the steps 12. The left-right direction in Fig. 3 represents the width direction of the steps 12. Fig. 4 is a cross-sectional view showing the IV-IV cross section in Fig. 3.

[0020] As shown in Figures 3 and 4, a plurality of grooves 12a are formed on the top surface of the step 12. Each groove 12a extends along the movement direction of the step 12. The extension direction of each groove 12a is perpendicular to the width direction of the step 12. Each groove 12a has a uniform cross-sectional shape with a bottom surface and a pair of side wall surfaces. A cleat 12b with a convex cross-sectional shape is formed between two adjacent grooves 12a.

[0021] The comb plate 40 has a comb plate body 41 and a plurality of comb teeth 42. The comb plate body 41 has a plate-like shape and is fixed to the boarding and disembarking plate 30. Each comb tooth 42 protrudes from the comb plate body 41 along the movement direction of the step 12. Each comb tooth 42 is inserted into a corresponding one of the plurality of grooves 12a.

[0022] A light source 50 is provided below the board 30. The light source 50 is fixed to the underside of the board 30. The light source 50 is provided in a position that does not interfere with the movement of the step 12. The light source 50 may be provided below the comb plate body 41.

[0023] The light source 50 is configured to emit light toward the plurality of comb teeth 42. In Fig. 4, an example of the direction of emission of light from the light source 50 is indicated by a dashed arrow. It is desirable that the emission direction of light from the light source 50 be downward rather than horizontal.

[0024] In this embodiment, the light source 50 is turned on when the operation mode of the escalator 100 is set to maintenance mode, and is turned off when the operation mode of the escalator 100 is set to a mode other than maintenance mode.

[0025] The light source 50 in this embodiment is a linear light source that extends linearly in the width direction of the step 12. The linear light source is configured, for example, by arranging a plurality of point light sources in a line. The width of the light source 50 in the width direction of the step 12 is wider than the distance between the comb teeth 42 located at both ends in the width direction of the step 12. This allows the light source 50 to irradiate all of the comb teeth 42 with light in a direction along the extension direction of the groove 12a in a plan view.

[0026] Next, a method for checking whether or not the comb teeth 42 are damaged in the passenger conveyor according to this embodiment will be described. Fig. 5 is a diagram showing a state in which a comb tooth is missing due to damage in the passenger conveyor according to this embodiment. In Fig. 5, among the multiple comb teeth 42, comb tooth 42-1 that is missing due to damage is represented by a two-dot chain line.

[0027] When a maintenance worker sets the operation mode of escalator 100 to the maintenance mode, light source 50 is turned on. As a result, light is emitted from light source 50 toward the plurality of comb teeth 42.

[0028] A portion of the light emitted from the light source 50 is blocked by each comb tooth 42. A portion of the remaining light passes through the gaps between the comb teeth 42 and the grooves 12a and leaks out of the comb plate 40 along each groove 12a.

[0029] When the comb tooth 42-1 is damaged, less light is blocked by the comb tooth 42-1. Therefore, the amount of light leaking from the comb tooth 42-1 is greater than that from the undamaged comb tooth 42. Therefore, the bottom and side wall surfaces of the groove 12a corresponding to the comb tooth 42-1 that are located outside the comb plate 40 are illuminated more brightly by the leaked light than the other grooves 12a. In FIG. 5, an example of the area of ​​the groove 12a corresponding to the comb tooth 42-1 that is illuminated more brightly by the leaked light than the other grooves 12a is indicated by dot hatching.

[0030] A maintenance worker can recognize that the comb tooth 42-1 is damaged by the difference in brightness of the grooves 12a caused by the difference in the amount of light leakage. Therefore, according to this embodiment, it is easy to visually check whether or not each comb tooth 42 is damaged.

[0031] As described above, the escalator 100 according to this embodiment includes steps 12, boarding and alighting plates 30, and comb plate 40. The steps 12 are configured to move in a circular manner. The boarding and alighting plates 30 are provided at both ends of the path of movement of the steps 12. The comb plate 40 is provided at the end of the boarding and alighting plate 30 on the step 12 side. Here, the escalator 100 is an example of a passenger conveyor.

[0032] A plurality of grooves 12a are formed on the upper surface of the step 12. The comb plate 40 has a plate-shaped comb plate body 41 and a plurality of comb teeth 42. The comb plate body 41 is fixed to the boarding / disembarking plate 30. Each of the plurality of comb teeth 42 protrudes from the comb plate body 41. Each of the plurality of comb teeth 42 is inserted into a corresponding one of the plurality of grooves 12a.

[0033] The escalator 100 further includes a light source 50. The light source 50 is provided below the boarding and alighting plate 30 or below the comb plate body 41. The light source 50 is configured to irradiate light toward the plurality of comb teeth 42.

[0034] According to this configuration, the amount of light leaking into each groove 12a can be varied depending on whether or not each comb tooth 42 is damaged. Therefore, a maintenance worker can easily visually check whether or not the comb tooth 42 is damaged.

[0035] In the escalator 100 according to this embodiment, the light source 50 is a linear light source extending in the width direction of the step 12.

[0036] According to this configuration, the plurality of comb teeth 42 can be irradiated with light in a direction along the extension direction of the grooves 12a in a plan view. Therefore, even if any of the plurality of comb teeth 42 is damaged, the range of the grooves 12a illuminated by the leaked light will be approximately the same in the extension direction of the grooves 12a. Therefore, even if any of the comb teeth 42 is damaged, the damage to the comb teeth 42 can be easily found by visual inspection by a maintenance worker.

[0037] In the above embodiment, the escalator 100 is taken as an example of the passenger conveyor, but the passenger conveyor may be a moving walkway. [Explanation of symbols]
