Note that the irradiation devices 8 may be arranged at both ends of the balustrade section 7 in the first lateral direction D1, for example, as in the present embodiment; It may be arranged only at one end of D1.

The balustrade section 7 may include, for example, an annular handrail belt 9 that rotates endlessly and a balustrade body section 10 that supports the handrail belt 9, as in the present embodiment. Note that, for example, the handrail belt 9 may be driven by the drive unit 5, and the handrail belt 9 may run in synchronization with the running in step 3b.

For example, the handrail belt 9 includes, as in the present embodiment, a circular arc portion 9a disposed at an end in the first lateral direction D1, and a first straight portion extending from the upper end of the circular arc portion 9a along the first lateral direction D1. 9b, and a second linear portion 9c extending from the lower end of the arcuate portion 9a in the first horizontal direction D1. Note that the arc portion 9a may extend in a semicircular arc shape when viewed in the second lateral direction D2, for example, as in the present embodiment.

For example, as in the present embodiment, the balustrade body part 10 includes a belt guide part 10a that guides the handrail belt 9, a guide support part 10b that supports the belt guide part 10a, a part of the handrail belt 9, and a guide support part. It may also include a parapet cover part 10c that covers the lower end part of the parapet cover part 10b.

For example, as in the present embodiment, the guide support portion 10b includes a first support plate 10d disposed at an end in the first horizontal direction D1, and a second support plate 10e connected to the first support plate 10d. You may be prepared. The first support plate 10d and the second support plate 10e may be made of different materials, for example. Although not particularly limited, the first support plate 10d may be made of, for example, metal (for example, stainless steel) or hard resin, and the second support plate 10e may be made of, for example, glass. You can.

As shown in FIGS. 2 and 3, the irradiation device 8 includes, for example, a light source 11 that irradiates the handrail belt 9 with ultraviolet rays, a device cover portion 12 that covers the light source 11 and the handrail belt 9, and a device cover portion 12 that covers the floor plate. It may also include a cover support part 13 supported by 1a.

The light source 11 is not particularly limited, but may be, for example, an LED or a lamp. Further, the number of light sources 11 is not particularly limited. In addition, the light source 11 may be fixed to the balustrade main body part 10 (for example, 1st support plate 10d of the guide support part 10b) by the fixing means 15 which is not shown in figure, for example.

The device cover section 12 may include a cover body 14 that covers the entire light source 11 and a part of the handrail belt 9, for example, as in the present embodiment. The cover body 14 may be fixed to the balustrade body 10 by, for example, a fixing means 15 (not shown). Thereby, the cover body 14 is fixed to the balustrade main body part 10, so the device cover part 12 is attached to the balustrade main body part 10.

Note that the configuration of the fixing means 15 is not particularly limited. For example, the fixing means 15 may fix the light source 11 to the first support plate 10d by connecting the light source 11 and the first support plate 10d. Further, for example, the fixing means 15 may fix the cover body 14 to the first support plate 10d by connecting the cover body 14 and the first support plate 10d.

For example, as in the present embodiment, the cover body 14 includes a pair of side covers 14a, 14a that cover the light source 11 and the handrail belt 9 from the second lateral direction D2, and a pair of side covers 14a, 14a that cover the light source 11 and the handrail belt 9 from the first lateral direction D1. It may be provided with a circumferential cover 14b that covers, and a pair of end covers 14c, 14c (see FIGS. 6 and 7) that cover between the side cover 14a and the circumferential cover 14b and the parapet 7.

Thereby, for example, leakage of ultraviolet rays emitted from the light source 11 to the outside of the irradiation device 8 can be suppressed. Note that the cover body 14 is not particularly limited, but may be made of, for example, a metal that can block ultraviolet rays (eg, stainless steel, etc.), a hard resin, or the like.

The cover body 14 may be arranged to cover the entire first support plate 10d and the entire fixing means 15, for example, as in the present embodiment. Thereby, the first support plate 10d and the fixing means 15 can be prevented from being visually recognized from the outside of the irradiation device 8.

Further, at least a portion of the cover body 14 may be configured to be detachable from the balustrade main body 10, for example. Specifically, for example, each of the covers 14a to 14c may be configured to be detachable from the balustrade main body 10. Thereby, for example, by removing at least a portion of the cover body 14 from the balustrade main body part 10, the inside of the irradiation device 8 (for example, the light source 11, etc.) can be easily checked.

Further, for example, as in the present embodiment, the device cover portion 12 is disposed upwardly away from the floor plate 1a, whereas the cover support portion 13 is disposed downwardly from the device cover portion 12 to the floor plate 1a. It may also be configured such that it extends to. Thereby, the device cover part 12 is supported by the floor plate 1a via the cover support part 13. Therefore, for example, the device cover section 12 can be securely fixed to the parapet section 7.

As a result, even when a downward force is applied to the device cover portion 12, the device cover portion 12 is prevented from shifting relative to the balustrade portion 7 or the device cover portion 12 is prevented from coming off the balustrade portion 7. I can do it. Note that there are cases where a downward force is applied to the device cover portion 12, for example, when a passenger leans on the device cover portion 12 from above, or when luggage is placed on the device cover portion 12.

Further, since the circumferential cover 14b is arranged along the handrail belt 9, the circumferential cover 14b extends in an arc shape when viewed in the second lateral direction D2. Thereby, for example, it is possible to prevent luggage from being placed on the device cover portion 12, that is, on the peripheral cover 14b. Moreover, for example, it is possible to suppress the cover body 14 from increasing in size when viewed in the second lateral direction D2.

Note that when checking the inside of the machine room 2a (see FIG. 1), the floor plate 1a is removed from the structure 2 (see FIG. 1). On the other hand, the cover support part 13 may be configured to be able to change the length extending downward from the device cover part 12, for example, as in the present embodiment. Thereby, by changing the length of the cover support part 13 extending from the device cover part 12, the cover support part 13 can be separated from the floor plate 1a.

Therefore, for example, the floor plate 1a can be easily attached to and detached from the structure 2. Note that the configuration of the cover support section 13 is not particularly limited, but the length of the cover support section 13 extending from the device cover section 12 may be changed by, for example, the screw mechanism 13a as in the present embodiment. good.

By the way, as shown in FIGS. 2 to 5, for example, the balustrade cover part 10c is provided with the balustrade entrance 10f at the end in the first lateral direction D1 through which the handrail belt 9 enters and exits, whereas the device cover The cover body 14 of the portion 12 may cover the parapet entrance 10f. This prevents the parapet entrance 10f from being exposed. Therefore, for example, it is possible to prevent the parapet entrance 10f from being visible from the outside of the irradiation device 8, and it is also possible to prevent passengers from approaching or touching the parapet entrance 10f, for example. .

Although not particularly limited, the gap between the cover body 14 and the parapet cover part 10c may be, for example, 20 mm or less at maximum, and preferably 5 mm or less at maximum, and, for example, the gap between the cover body 14 and More preferably, the balustrade cover portions 10c are in contact with each other. Note that FIGS. 4(a) and 5(a) show the case where the irradiation device 8 is provided, and FIG. 4(b) and FIG. 5(b) show the case where the irradiation device 8 is not provided.

Further, the device cover part 12 includes a device entrance 16a (see also FIGS. 6 and 7) through which the handrail belt 9 enters and exits, and the cover body 14 continuously extends from the device entrance 16a to the parapet entrance 10f, for example. It may be arranged so as to cover it. Thereby, the cover body 14 continuously covers the handrail belt 9 from the parapet entrance 10f to the device entrance 16a.

Therefore, the device cover portion 12 has only one exposed entrance/exit (device entrance/exit) 16a. On the other hand, since the parapet entrance 10f is covered by the cover body 14, the parapet entrance 10f is not exposed. This can prevent the number of exposed entrances and exits from increasing due to the irradiation device 8 being attached to the parapet 7.

Specifically, if the irradiation device 8 is not attached to the balustrade part 7 at one end of the first lateral direction D1 of the balustrade device 4, the exposed entrance is one of the balustrade entrances 10f, and the irradiation When the device 8 is attached to the parapet 7, the exposed doorway is one of the device doorways 16a.

Further, the cover body 14 may cover the entire arc portion 9a of the handrail belt 9, for example, as in this embodiment. Thereby, the cover body 14 is arranged so as to continuously cover the handrail belt 9 from the handrail entrance 10f to at least the upper end of the arc portion 9a.

Therefore, for example, the device entrance 16a can be prevented from being hidden by the parapet 7 for passengers who are transported on step 3b (see FIG. 1). Passengers can easily see the device entrance/exit 16a. As a result, for example, passengers can be prevented from getting caught by the handrail belt 9 up to the device entrance/exit 16a, and therefore, for example, passengers can be prevented from touching the device entrance/exit 16a.

As shown in FIGS. 6 and 7, for example, the device cover section 12 includes a movable body 16 that is movable with respect to the cover body 14, and the movable body 16 is provided with a device entrance/exit 16a inside. It may be a configuration. The irradiation device 8 also includes, for example, an elastic section 17 that applies an elastic restoring force to the movable body 16 and a detection section 18 that detects movement of the movable body 16 with respect to the cover body 14, as in the present embodiment. may be provided.

The movable body 16 may include, for example, as in the present embodiment, a cylindrical portion 16b having an apparatus entrance/exit 16a therein, and a flange portion 16c protruding outward from the cylindrical portion 16b. Note that the movable body 16 may be made of, for example, an elastic material (eg, rubber), although it is not particularly limited. In the movable body 16, for example, the first straight portion 9b of the handrail belt 9 may be arranged inside the cylindrical portion 16b, as in the present embodiment.

The elastic portion 17 is not particularly limited, but may be, for example, a helical spring as in the present embodiment, or may be, for example, rubber. In addition, the elastic part 17 may be fixed to the 1st support plate 10d of the balustrade main body part 10 by the fixing means 15, for example like this embodiment.

The detection unit 18 is not particularly limited, but may be, for example, a contact sensor as in this embodiment, or may be a variety of sensors such as a photoelectric sensor. In addition, the detection part 18 may be fixed to the 1st support plate 10d of the balustrade main body part 10 by the fixing means 15, for example like this embodiment.

Thereby, when no external force is applied to the movable body 16, the movable body 16 is located at the reference position by the elastic portion 17. If a passenger's hand hits the movable body 16 while the passenger is caught by the handrail belt 9, force is applied to the movable body 16, so that the movable body 16 responds to the elastic restoring force of the elastic portion 17. On the contrary, it moves relative to the cover body 14. Therefore, for example, the impact applied to the hand from the movable body 16 can be reduced.

Further, for example, when the movable body 16 moves relative to the cover body 14 by a distance equal to or greater than the set distance, the detection unit 18 detects the movement of the movable body 16 with respect to the cover body 14 . As a result, it is possible to detect that a force is applied to the movable body 16, so that, for example, it is possible to detect that a passenger's hand has hit the movable body 16 when the passenger is caught by the handrail belt 9. .

Note that when a hand hits the movable body 16, the speed of travel of the handrail belt 9 and the step 3b (see FIG. 1) may be changed by the processing device 6 (see FIG. 1), for example. Specifically, the running of the handrail belt 9 and the step 3b may be stopped (the running speed may be set to zero), or the running speed may be reduced.

Further, when a hand hits the movable body 16, an output unit (not shown) may output information by the processing device 6, for example. Specifically, for example, an audio unit (eg, a buzzer, etc.) may output an alarm sound, or, for example, a display unit (eg, an indicator light, etc.) may output an alarm display.
