[0016] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0017] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0018] Hereinafter, one embodiment of a passenger conveyor will be described with reference to Figures 1 to 8. Note that in each figure, the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match.

[0019] As shown in Figure 1, the passenger conveyor 1 may include, for example, a structure 2 installed on a main body, a transport section 3 for transporting passengers (people), a pair of balustrade sections 4 (only one is shown in Figure 1) arranged to sandwich the transport section 3 in a first direction D1, a drive section 5 for driving the transport section 3 and the balustrade sections 4, and a processing section 6 for controlling the entire device.

[0020] In each figure, the first direction D1 is the first horizontal direction (also called the "width direction") D1 which is a direction parallel to the horizontal direction, the second direction D2 is the second horizontal direction (also called the "front-to-back direction") D2 which is a direction parallel to the horizontal direction and perpendicular to the first horizontal direction D1, and the third direction D3 is a vertical direction perpendicular to the first horizontal direction D1 and the second horizontal direction D2, and is the up-down direction D3.

[0021] The passenger conveyor 1 according to this embodiment is an escalator with a stepped tread to transport passengers, but is not limited to this configuration. For example, the passenger conveyor 1 may be a moving walkway with a flat tread to transport passengers. In this embodiment, the passenger conveyor 1 is configured to transport passengers diagonally upward, but the passenger conveyor 1 may also be configured to transport passengers diagonally downward.

[0022] The structure 2 may, for example, include machine rooms 2a, 2b arranged at each end in the second horizontal direction D2 as in this embodiment. The machine room 2a arranged at the bottom is referred to as the first machine room 2a, and the machine room 2b arranged at the top is referred to as the second machine room 2b. The structure 2 may also be, for example, a truss structure or a girder structure composed of multiple frame materials.

[0023] The passenger conveyor 1 may, for example, include a floor plate 1a attached to the structure 2 so as to cover the machine rooms 2a, 2b from above, as in this embodiment. As a result, the floor plate 1a constitutes boarding and disembarking sections 1b, 1c arranged at each end of the conveying section 3 in the second lateral direction D2 for getting on and off the conveying section 3.

[0024] In this embodiment, the passenger conveyor 1 is configured to transport passengers diagonally upward, so the first boarding and alighting section 1b located at the bottom becomes the boarding section 1b, and the second boarding and alighting section 1c located at the top becomes the disembarking section 1c. The passenger conveyor 1 may also be configured to transport passengers diagonally downward.

[0025] The transport unit 3 includes an annular running unit 3a that rotates endlessly when driven by a drive unit 5, and a plurality of steps 7 that are rotatably connected to the running unit 3a and have tread surfaces for people to stand on. A pair of running units 3a are provided spaced apart from each other in the first horizontal direction D1 (only one is shown in FIG. 1).

[0026] The conveying section 3 includes a connecting shaft (not shown) connected to each of the pair of running sections 3a, 3a, and the step 7 is rotatably connected to the connecting shaft. As a result, the step 7 is rotatably connected to each of the running sections 3a. Although not particularly limited, the running sections 3a may be, for example, roller chains.

[0027] 2 to 4, the step 7 includes a step body 7a and a guide roller 7b rotatably connected to the step body 7a. The step body 7a includes a tread portion 7c on which a person stands, a riser portion 7d extending in a curved shape from a first edge of the tread portion 7c in the front-rear direction D2, and a connecting portion 7e rotatably connected to the connecting shaft of the conveying unit 3.

[0028] The tread portion 7c has a plurality of ridges 71, 72 arranged in the width direction D1 and extending along the front-rear direction D2. The ridges 71, 72 have first ridges 71 and second ridges 72 arranged alternately in the width direction D1. The end of the first ridge 71 protrudes in a comb-teeth shape from the edge of the tread portion 7c to one side in the front-rear direction D2. The end of the second ridge 72 protrudes in a comb-teeth shape from the edge of the tread portion 7c to the other side in the front-rear direction D2. As a result, when the tread portions 7c, 7c of the steps 7, 7 adjacent to each other in the front-rear direction D2 are flat, the end of the first ridge 71 of the step 7 fits into the gap between the ends of the second ridges 72 of another step 7 adjacent to each other in the front-rear direction D2, and the end of the second ridge 72 of the step 7 fits into the gap between the ends of the first ridges 71 of another step 7 adjacent to each other in the front-rear direction D2.

[0029] The rise portion 7d also includes a plurality of third ridges 73 aligned in the width direction D1 and extending along the up-down direction D3. The third ridges 73 are disposed at the same positions in the width direction D1 as the second ridges 72. As a result, when the tread portions 7c, 7c of the steps 7, 7 adjacent to each other in the front-rear direction D2 form a staircase shape, the third ridges 73 of one step 7 fit into the gaps between the ends of the first ridges 71 of another step 7 adjacent to each other in the front-rear direction D2.

[0030] The tread portion 7c may also include a base portion 74 on which a person stands, and a boundary portion (also called a demarcation portion) 75 that is disposed on the periphery and has a color (e.g., yellow) different from the color of the base portion 74. Although not particularly limited, the base portion 74 may be formed of, for example, a metal (e.g., aluminum, steel, stainless steel, etc.), and the boundary portion 75 may be formed of, for example, a hard resin. The boundary portion 75 may be provided on three sides of the periphery of the tread portion 7c, as shown in FIG. 2. Specifically, the boundary portion 75 may be provided on both end edges of the tread portion 7c in the width direction D1 and on one side edge of the tread portion 7c in the front-rear direction D2.

[0031] The step 7 includes a light guide plate 8. For ease of explanation, the light guide plate 8 is hatched in Figs. 3 to 5 and the like. Although not particularly limited, the light guide plate 8 is embedded in the upper end of the rise portion 7d. Furthermore, although not particularly limited, the light guide plate 8 is embedded over the entire width direction D1 of the rise portion 7d.

[0032] The light guide plate 8 is formed of, for example, an acrylic resin having optical transparency. As shown in Fig. 5, the light guide plate 8 has an incident surface 8a constituting a part of the side surface of the step 7 in the width direction D1, a back surface 8b extending from the incident surface 8a toward the center of the step 7 in the width direction D1, and an exit surface 8c facing the back surface 8b.

[0033] The incident surface 8a is formed to be flush with the side surface of the step 7. In this embodiment, the light guide plate 8 is embedded in the entire step 7 in the width direction D1, and therefore has an incident surface 8a at each end in the width direction D1.

[0034] Furthermore, the exit surface 8c constitutes a part of the surface of the rise portion 7d. The exit surface 8c is not particularly limited, but may be located at the upper end of the surface of the rise portion 7d. The exit surface 8c may also include a fourth ridge 76 (see FIG. 3) that is continuous with the third ridge 73 of the rise portion 7d.

[0035] The back surface 8b faces the inside of the step 7. The step 7 is provided with a reflector 81 disposed on the outside of the back surface 8b. The reflector 81 reflects the light propagating through the light guide plate 8. Here, reflecting light includes not only specular reflection of the light but also diffuse reflection of the light. By providing the reflector 81 adjacent to the back surface 8b, the light incident from the entrance surface 8a and propagating through the light guide plate 8 is reflected by the reflector 81 and exits from the exit surface 8c, so that the light guide plate 8 can emit light.

[0036] As shown in FIG. 8, the reflector 81 may include reflective dots 81a that scatter light. When the light propagating through the light guide plate 8 hits the reflective dots 81a, it is diffusely reflected. The reflective dots 81a are printed on the back surface 8b, for example. The density of the reflective dots 81a per unit area may be higher as it is farther away from the incident surface 8a. This increases the amount of light reflected at the center of the width direction D1 of the reflector 81, so that the light incident from the incident surface 8a attenuates as it is farther away from the incident surface 8a, and the center of the width direction D1 of the exit surface 8c is prevented from becoming dark. As a result, the unevenness of light in the width direction D1 of the light guide plate 8 can be reduced.

[0037] The light guide plate 8 may include a reflective sheet (not shown) on the outside of the back surface 8b, and a diffusion sheet (not shown) on the outside of the exit surface 8c.

[0038] 1, for example, as in this embodiment, the driving unit 5 may include a rotating unit 5a around which a first end of the running unit 3a in the second horizontal direction D2 is wound and which rotates about an axis in the first horizontal direction D1, a supporting unit 5b that supports a second end of the running unit 3a in the second horizontal direction D2, and a driving source 5c that rotates the rotating unit 5a. As a result, the step 7 is reversed by the rotating unit 5a and also reversed by the supporting unit 5b.

[0039] Although not particularly limited, the rotating part 5a may be, for example, a sprocket. Furthermore, although not particularly limited, the support part 5b may be, for example, a guide member that guides the running part 3a to rotate in the reverse direction, or may be, for example, a rotating member (for example, a sprocket) around which the running part 3a is wound and which rotates about an axis in the first horizontal direction D1. Furthermore, although not particularly limited, the driving source 5c may be, for example, a motor.

[0040] 1 and 6, the balustrade section 4 may include, for example, an endlessly rotating circular handrail belt 4a, a balustrade main body section 4b that supports the handrail belt 4a, and a cover section 4c that covers the lower part of the balustrade main body section 4b. Note that, for example, the handrail belt 4a may be driven by the drive section 5, and the running of the handrail belt 4a may be synchronized with the running of the steps 7.

[0041] As shown in Fig. 6, the balustrade main body 4b may include a plurality of interior panels 4d. The plurality of interior panels 4d are arranged in parallel along the direction in which the steps 7 run (hereinafter also referred to as the running direction of the steps 7). The cover portion 4c may include a skirt panel 4e disposed adjacent to the side of the step 7, and a molding 4f connected to an upper portion of the skirt panel 4e. The skirt panel 4e extends along the running direction of the steps 7. The upper portion of the molding 4f is connected to the interior panel 4d.

[0042] The passenger conveyor 1 is equipped with light sources 9A and 9B that emit light toward the side of the step 7. The light sources 9A and 9B extend along the traveling direction of the step 7. Although not particularly limited, the light sources 9A and 9B are arranged inside the skirt panel 4e. In this embodiment, the light sources 9A and 9B are each arranged inside the skirt panel 4e of a pair of balustrades 4. In this embodiment, the light source 9A and the light source 9B are each composed of separate light sources, but the light source 9A and the light source 9B may be composed of a continuous, integrated light source.

[0043] The light sources 9A and 9B are, for example, LEDs. The light source 9A emits, for example, white light, and the light source 9B emits, for example, green light. The light sources 9A and 9B may emit light of different colors or the same color.

[0044] The skirt panel 4e has a passing portion 41 through which the light from the light sources 9A and 9B passes. The passing portion 41 is an opening or a light-transmitting portion having optical transparency. The passing portion 41 is disposed opposite to a side surface of the step 7 and extends along the running direction of the step 7.

[0045] The passing portion 41 is disposed at a height facing the incident surface 8a of the light guide plate 8. This allows the light sources 9A and 9B to irradiate light toward the incident surface 8a of the light guide plate 8 through the passing portion 41. The light irradiated from the light sources 9A and 9B is incident from the incident surface 8a, then reflected by the reflector 81 and emitted from the emission surface 8c. As shown in FIG. 6, when the step 7 runs diagonally upward, the light guide plate 8 at the upper end of the rise portion 7d shines white, improving the design. On the other hand, as shown in FIG. 7, when the step 7 runs horizontally, the green light emitted from the light guide plate 8 leaks out from the gap between the tread portion 7c of the adjacent step 7. This makes it easier for a person standing on the tread portion 7c to properly distinguish between the running steps 7, thereby improving the safety of the feet.

[0046] From the above, the passenger conveyor 1, as in this embodiment, Step 7: Run light sources 9A and 9B that irradiate light toward the side surfaces of the step 7 in the first horizontal direction D1; The step 7 includes a tread portion 7c on which a person stands, a rise portion 7d extending in a curved shape from a first edge of the tread portion 7c in a second horizontal direction D2 perpendicular to the first horizontal direction D1, and a light guiding portion (in this embodiment, a light guiding plate) 8 extending in the first horizontal direction D1. The light guide portion (in this embodiment, a light guide plate) 8 includes an incident surface 8a that constitutes a part of the side surface of the step 7 and into which light from the light sources 9A and 9B is incident, and an exit surface 8c that constitutes a part of at least one surface of the tread portion 7c and the rise portion 7d and that emits the light incident from the incident surface 8a. This configuration is preferred.

[0047] According to this configuration, the light sources 9A and 9B irradiate light from outside the step 7 toward the side surface of the step 7, so there is no need to place the light sources 9A and 9B inside the step 7. Furthermore, by making the light irradiated from the light sources 9A and 9B incident on the entrance surface 8a of the light guide plate 8, the light is emitted from the exit surface 8c of the light guide plate 8, so that the light can be irradiated from the step 7.

[0048] In addition, in the passenger conveyor 1, as in this embodiment, The exit surface 8c is disposed at the upper end of the surface of the rise portion 7d. This configuration is preferred.

[0049] With this configuration, when the steps 7 run diagonally upward, the exit surface 8c located at the upper end of the rise portion 7d lights up, improving the design, and when the steps 7 run horizontally, light leaks out through the gap between the tread portions 7c of adjacent steps 7, making it easier to properly distinguish between the running steps 7, thereby improving footing safety.

[0050] In addition, in the passenger conveyor 1, as in this embodiment, The step 7 is provided with a reflector 81 arranged on the outer side of a surface (in this embodiment, a back surface) 8b facing the emission surface 8c, and reflects light propagating through the light guide section (in this embodiment, a light guide plate) 8; The reflector 81 includes a plurality of reflecting portions (in this embodiment, reflecting dots) 81a that reflect light. The density per unit area of ​​the reflective portion (in this embodiment, the reflective dot) 81a becomes higher as it is farther away from the incident surface 8a. This configuration is preferred.

[0051] According to such a configuration, it is possible to prevent the central portion of the light guide plate 8 in the width direction D1 from becoming dark, and therefore it is possible to reduce unevenness in light in the width direction D1 of the light guide plate 8.

[0052] The passenger conveyor 1 is not limited to the configuration of the embodiment described above, nor is it limited to the above-mentioned effects. Furthermore, the passenger conveyor 1 can be modified in various ways without departing from the spirit of the present invention. For example, it is possible to select one or more of the configurations and methods of the various modified examples described below and adopt them in the configurations and methods of the embodiment described above.

[0053] (A) In the passenger conveyor 1 according to the above embodiment, the exit surface 8c is arranged at the upper end of the surface of the riser 7d. However, the passenger conveyor 1 is not limited to such a configuration. For example, the exit surface 8c may be arranged at a place other than the upper end of the surface of the riser 7d.

[0054] As shown in Fig. 9, the exit surface 8c may be arranged at the lower end of the surface of the riser 7d. With this arrangement, when the steps 7 run diagonally upward, the light emitted from the exit surface 8c is reflected by the end surface of the tread portion 7c of the adjacent step 7, causing the riser 7d of the step 7 to shine, improving the design. The exit surface 8c may be arranged at the center of the surface of the riser 7d in the up-down direction D3.

[0055] 10, the light emitting surface 8c may be disposed on the end surface of the second edge of the tread portion 7c in the second horizontal direction D2. With this configuration, when the steps 7 run horizontally, light leaks out from the gap between the tread portions 7c of adjacent steps 7, making it easier to distinguish between the running steps 7, improving footing safety. When the steps 7 run diagonally upward, the light emitted from the light emitting surface 8c is reflected by the lower end of the surface of the rise portion 7d of the adjacent step 7, causing the rise portion 7d of the step 7 to shine, improving the design.

[0056] Furthermore, when the light guide plate 8 is positioned in the position shown in Figure 9 (similar to when it is positioned in the position shown in Figure 10), as shown in Figure 11, the passenger conveyor 1 may be configured to have a skirt panel 4e arranged close to the side of the step 7, the skirt panel 4e having a passing portion 41 through which light from the light source 9C passes, the passing portion 41 extending along the running direction of the step 7 and arranged so as to overlap with the step 7 over its entire length when viewed in the first lateral direction D1.

[0057] According to such a configuration, it is possible to prevent passengers from viewing the passing portion 41. In addition, since it is possible to prevent light from being directly emitted from the passing portion 41 to the outside, even if the intensity of the light emitted from the light source 9C is increased, for example, passengers are not made uncomfortable.

[0058] 12, the emission surface 8c may be arranged on the upper surface of the tread portion 7c. With such a configuration, it becomes easier to distinguish between steps 7 that are being walked on, improving safety around the feet.

[0059] (B) In addition, in the passenger conveyor 1 according to the above embodiment, the passing section 41 is configured to extend continuously along the running direction of the steps 7. However, the passenger conveyor 1 is not limited to such a configuration. For example, the passing section 41 may be configured to extend intermittently along the running direction of the steps 7.

[0060] (C) In the passenger conveyor 1 according to the embodiment, the step 7 is arranged on the outside of the back surface 8b facing the exit surface 8c, and includes a reflector 81 that reflects the light propagated through the light guide plate 8, and the reflector 81 includes a plurality of reflective dots 81a that reflect the light, and the density of the reflective dots 81a per unit area increases with distance from the entrance surface 8a. However, the passenger conveyor 1 is not limited to such a configuration. For example, the reflector 81 may be formed on the back surface 8b facing the exit surface 8c, and includes a reflector 81 that reflects the light propagated through the light guide plate 8, and the reflector 81 includes a plurality of grooves (not shown) that reflect the light, and the density of the grooves per unit area increases with distance from the entrance surface 8a. The grooves are formed, for example, by laser processing. The density of the reflective dots 81a and the grooves per unit area may be constant in the width direction D1.

[0061] 13, the step 7 may be configured to include a reflector 81 arranged on the outside of the back surface 8b facing the exit surface 8c, which reflects the light propagating through the light guide plate 8, and a colored layer 82 arranged on the outside of the reflector 81 and having a color different from the color of the light irradiated from the light sources 9A to 9C. By making the colored layer 82 the same color as the boundary portion 75 (e.g., yellow), when the light from the light sources 9A to 9C is not irradiated onto the light guide plate 8, the light guide plate 8 can exhibit a function equivalent to that of the boundary portion 75 due to the color of the colored layer 82. On the other hand, by irradiating the light from the light sources 9A to 9C (e.g., green light) onto the light guide plate 8, it becomes easier to distinguish between the steps 7 that are being traveled, thereby improving the safety of the feet.

[0062] (E) In the passenger conveyor 1 according to the above embodiment, the light guide plate 8 is embedded in the entire width direction D1 of the tread portion 7c or the riser portion 7d. However, the passenger conveyor 1 is not limited to such a configuration. For example, the light guide plate 8 may be embedded in a part of the width direction D1 of the tread portion 7c or the riser portion 7d.

[0063] (F) Furthermore, in the passenger conveyor 1 according to the above embodiment, each step 7 is provided with one light guide plate 8, but each step 7 may be provided with multiple light guide plates 8. Furthermore, the passenger conveyor 1 may be provided with multiple light sources 9A-9C. [Explanation of symbols]
