Modes for Carrying Out the Invention

[0009] Embodiment 1. FIG. 1 is a side view showing an escalator in which a railing lighting device of an escalator according to Embodiment 1 is installed. The escalator, which is a passenger conveyor, includes a main frame 1, a pair of railings 2, a pair of moving handrails 3, a pair of railing lighting devices 4, and a plurality of steps 5.

[0010] The main frame 1 is provided across the lower floor 101 and the upper floor 102. A plurality of steps 5 are provided on the main frame 1. The plurality of steps 5 are arranged side by side in an endless manner. By the circulating movement of the plurality of steps 5, the users of the escalator riding on the steps 5 move between the lower floor boarding and alighting opening 103 and the upper floor boarding and alighting opening 104.

[0011] A pair of handrails 2 are supported by the main frame 1. The pair of handrails 2 are arranged apart from each other in the width direction of the main frame 1. Also, the pair of handrails 2 are arranged so as to sandwich the steps 5 in the width direction of the steps 5 when viewed from above. Therefore, the users of the escalator riding on the steps 5 move between the pair of handrails 2. Each handrail 2 is provided across the lower floor boarding and alighting opening 103 and the upper floor boarding and alighting opening 104.

[0012] A pair of moving handrails 3 are provided one by one on each handrail 2. Each moving handrail 3 is provided across the lower floor boarding and alighting opening 103 and the upper floor boarding and alighting opening 104. Each moving handrail 3 circulates in synchronization with the circulating movement of the steps 5.

[0013] A pair of handrail lighting devices 4 are provided one by one on each handrail 2. Each handrail lighting device 4 has a light guide member 401 and a light emitting device 402 that emits light passing through the light guide member 401.

[0014] The light guide member 401 is provided on the handrail 2 across the lower floor boarding and alighting opening 103 and the upper floor boarding and alighting opening 104. In other words, the light guide member 401 is provided on the handrail 2 across the boarding and alighting openings. The shape of the light guide member 401 is a long shape. The light guide member 401 is arranged so as to extend along the forward path side portion of the moving handrail 3.

[0015] The light-emitting device 402 is disposed to face one end portion in the longitudinal direction of the light guide member 401. One end portion in the longitudinal direction of the light guide member 401 is disposed on the lower floor side horizontal portion of the railing 2. Therefore, the light-emitting device 402 is disposed on the lower floor side horizontal portion of the railing 2. The lower floor side horizontal portion of the railing 2 is a portion of the railing 2 that is adjacent to the lower floor side boarding and alighting opening 103 in the width direction of the step 5. Therefore, the light-emitting device 402 is disposed on a portion of the railing 2 that is adjacent to the lower floor side boarding and alighting opening 103 in the width direction of the step 5. The light-emitting device 402 is disposed such that the light emitted from the light-emitting device 402 enters the inside of the light guide member 401 from one end portion in the longitudinal direction of the light guide member 401.

[0016] Note that the light-emitting device 402 may be disposed to face not only one end portion in the longitudinal direction of the light guide member 401 but also the other end portion in the longitudinal direction of the light guide member 401. That is, the light-emitting device 402 may be disposed not only on the lower floor side horizontal portion of the railing 2 but also on the upper floor side horizontal portion of the railing 2. The upper floor side horizontal portion of the railing 2 is a portion of the railing 2 that is adjacent to the upper floor side boarding and alighting opening 104 in the width direction of the step 5. Therefore, the light-emitting device 402 may be disposed on a portion of the railing 2 that is adjacent to the upper floor side boarding and alighting opening 104 in the width direction of the step 5. Further, the light-emitting device 402 may be disposed on both the lower floor side horizontal portion of the railing 2 and the upper floor side horizontal portion of the railing 2.

[0017] Further, the light-emitting device 402 is not limited to the configuration disposed outside the light guide member 401, and may be a configuration disposed inside the light guide member 401. A part of the light that has entered the inside of the light guide member 401 from one end portion in the longitudinal direction of the light guide member 401 is adapted to travel through the light guide member 401 to the other end portion in the longitudinal direction of the light guide member 401.

[0018] FIG. 2 is a configuration diagram showing the railing lighting device 4 of FIG. 1. FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2. The light guide member 401 is formed in a tubular shape. The shape of the inner wall surface of the light guide member 401 is a cylindrical shape. Note that the light guide member 401 is not limited to a tubular shape, and may be other shapes.

[0019] The light guide member 401 has a light reflection part 403 that reflects light and a light reflection and transmission part 404 that reflects part of the light and transmits part of the light. The light reflection part 403 is arranged in the upper part of the cross section perpendicular to the longitudinal direction in the light guide member 401, and the light reflection and transmission part 404 is arranged in the lower part of the cross section perpendicular to the longitudinal direction in the light guide member 401.

[0020] The light reflection part 403 is composed of a mirror. Note that the light reflection part 403 is not limited to a mirror, and any member that is mirror-finished to reflect light may be used.

[0021] The light reflection and transmission part 404 is composed of a half mirror. Note that the light reflection and transmission part 404 is not limited to a half mirror, and any member that reflects part of the light and transmits part of the light may be used.

[0022] The light emitted from the light emitting device 402 is incident from one end in the longitudinal direction of the light guide member 401 into the inside of the light guide member 401. The light incident from one end in the longitudinal direction of the light guide member 401 into the inside of the light guide member 401 passes through the light guide member 401. Part of the light passing through the light guide member 401 is reflected by the light reflection part 403 and further advances through the light guide member 401 toward the other end in the longitudinal direction of the light guide member 401. Also, part of the light passing through the light guide member 401 is reflected by the light reflection and transmission part 404 and further advances through the light guide member 401 toward the other end in the longitudinal direction of the light guide member 401.

[0023] Part of the light passing through the light guide member 401 passes through the light reflection and transmission part 404 and exits to the outside of the light guide member 401. The light exiting to the outside of the light guide member 401 illuminates the railing 2. The light reflection and transmission part 404 is arranged over the entire longitudinal direction of the light guide member 401. Thereby, the entire railing 2 is illuminated. The light passing through the light reflection and transmission part 404 is uniform over the entire longitudinal direction of the light guide member 401. Therefore, the railing is uniformly illuminated over the entire longitudinal direction.

[0024] The light-emitting device 402 has an LED (LIGHT EMITTING DIODE) and a power supply device that supplies current to the LED. Note that the light-emitting device 402 is not limited to an LED and may be, for example, a fluorescent lamp.

[0025] When current is supplied from the power supply device to the LED, the LED lights up. When the LED lights up, the light-emitting device 402 emits light.

[0026] When the light-emitting device 402 is lit for a long period of time, it is necessary to replace the light-emitting device 402. The light-emitting device 402 is arranged only on the lower floor side horizontal part in the railing 2. Thereby, an operator can replace the light-emitting device 402 by entering the lower floor side boarding and alighting opening 103. As a result, the operator can easily replace the light-emitting device 402.

[0027] As described above, the escalator railing lighting device 4 according to Embodiment 1 includes a light guide member 401 and a light-emitting device 402 that emits light passing through the light guide member 401. The light guide member 401 is provided in the railing 2 across between the lower floor side boarding and alighting opening 103 and the upper floor side boarding and alighting opening 104. Further, the light guide member 401 has a light reflection part 403 that reflects light and a light reflection and transmission part 404 that reflects a part of the light and transmits a part of the light. The light emitted from the light-emitting device 402 is reflected by the light reflection part 403 and the light reflection and transmission part 404 and passes through the light guide member 401. The light passing through the light guide member 401 passes through the light reflection and transmission part 404 and illuminates the railing 2. According to this configuration, the light-emitting device 402 is installed on the railing 2 so that light passes through the light guide member 401. Thereby, the place where the light-emitting device 402 is installed can be made the longitudinal end of the light guide member 401. Therefore, compared with the conventional escalator railing lighting device in which the light-emitting device 402 is installed at a plurality of places across the entire longitudinal direction of the railing 2, the number of places where the light-emitting device 402 is installed can be reduced. As a result, the efficiency of the replacement work of the light-emitting device 402 can be improved.

[0028] In addition, the light reflection and transmission part 404 reflects part of the light and transmits part of the light. Part of the light emitted from the light emitting device 402 is reflected by the light reflection part 403 and the light reflection and transmission part 404, and passes through the light reflection and transmission part 404. According to this configuration, the light passing through the light reflection and transmission part 404 can be made uniform over the entire longitudinal direction of the light guide member 401. Thereby, the light can be uniformly illuminated over the entire longitudinal direction of the railing 2.

[0029] Embodiment 2. FIG. 4 is a cross-sectional view showing a main part of a railing lighting device of an escalator according to Embodiment 2. The railing lighting device 4 of the escalator according to Embodiment 2 further includes a diffusion device 6.

[0030] The diffusion device 6 is provided inside the light guide member 401. The diffusion device 6 diffuses light. In FIG. 4, one diffusion device 6 is shown, but a plurality of diffusion devices 6 are arranged side by side at intervals in the longitudinal direction of the light guide member 401 in the light guide member 401.

[0031] The light emitted from the light emitting device 402 is diffused by the diffusion device 6. The light diffused by the diffusion device 6 passes through the light reflection and transmission part 404 and illuminates the railing 2.

[0032] Each diffusion device 6 has a blower device 601 that generates wind, a strip 602 arranged adjacent to the blower device 601 in the longitudinal direction of the light guide member 401, and a rotating shaft 603 that supports the strip 602.

[0033] FIG. 5 is a block diagram showing the blower device 601 of FIG. 4. The blower device 601 has a fan 604 and a drive device 605 that rotates the fan 604.

[0034] The fan 604 is made of a material through which light passes. When the fan 604 rotates, wind flowing in the longitudinal direction of the light guide member 401 is generated inside the light guide member 401.

[0035] The strip 602 has a metallic luster. The strip 602 is fluttered by the wind generated by the blower device 601. The light emitted from the light-emitting device 402 passes through the light guide member 401 and is diffusely reflected by hitting the fluttering strip 602.

[0036] The smaller the incident angle of the light incident on the light reflection and transmission part 404, the larger the amount of light transmitted through the light reflection and transmission part 404. The incident angle of the light incident on the light reflection and transmission part 404 is the angle between the plane perpendicular to the light reflection and transmission part 404 and the straight line along the traveling direction of the light when viewed from the direction perpendicular to the traveling direction of the light. When the light is diffusely reflected by the strip 602, the amount of light transmitted through the light reflection and transmission part 404 increases.

[0037] The driving of the driving device 605 is controlled by the control panel 7 of the escalator. The control panel 7 of the escalator controls the movement of the step 5.

[0038] FIG. 6 is a diagram showing a state in which the direction of the wind generated by the blower device 601 in FIG. 4 is switched. As shown in FIGS. 4 and 6, the blower device 601 is configured to switch the direction of the wind generated corresponding to the moving direction of the step 5. Specifically, the blower device 601 generates a wind flowing in a direction corresponding to the moving direction of the step 5.

[0039] The rotating shaft 603 is rotatably attached to the side wall of the light guide member 401. Thereby, when the direction of the wind generated by the blower device 601 is switched, the direction in which the strip 602 flutters changes corresponding to the switching of the wind.

[0040] Other configurations of the handrail lighting device 4 of the escalator according to Embodiment 2 are the same as those of the handrail lighting device 4 of the escalator according to Embodiment 1.

[0041] As described above, the handrail lighting device 4 according to the second embodiment includes a diffusion device 6. The diffusion device 6 is provided on the light guide member 401. Further, the diffusion device 6 diffuses light. The light emitted from the light emitting device 402 is diffused by the diffusion device 6 and transmitted through the light reflection and transmission portion 404. According to this configuration, the light reflection and transmission portion 404 can be more surely transmitted through the light passing through the light guide member 401 to illuminate the handrail 2.

[0042] Further, the diffusion device 6 has a blower device 601 and a strip 602. The blower device 601 generates wind. The strip 602 has a metallic luster. Further, the strip 602 is swayed by the wind generated by the blower device 601. The light emitted from the light emitting device 402 is diffused by hitting the swaying strip 602. According to this configuration, the light passing through the light guide member 401 can be more surely diffused.

[0043] Further, the blower device 601 switches the direction of the generated wind corresponding to the moving direction of the step 5. According to this configuration, by visually observing the direction in which the strip 602 sways by the user of the escalator, the user of the escalator can recognize the moving direction of the step 5. Therefore, the moving direction of the step 5 can be notified to the user of the escalator. Note that the light emitting device 402 may be configured to switch the color of the emitted light to different colors corresponding to the moving direction of the step 5. In this case, for example, when the escalator is running upward, the light emitting device 402 may emit red light, and when the escalator is running downward, the light emitting device 402 may emit green light. With this configuration, the moving direction of the step 5 can be more clearly notified to the user of the escalator.

[0044] In each of the embodiments, the handrail lighting device of the passenger conveyor has been described by taking the handrail lighting device of the escalator as an example. However, the handrail lighting device of the passenger conveyor is not limited to the handrail lighting device of the escalator, and may be, for example, a handrail lighting device of a moving walkway.
