(3) Structure of Lighting Device 70 in Inlet Section 46 Next, a structure in which the lighting device 70 penetrates into the inlet section 46 will be described. The lighting device 70 attached along the semicircular portion 36a at the end of the upper floor of the balustrade 36 as described above reaches the inlet portion 46 on the upper floor. At this position, the handrail rail 74 and the handrail belt 38 are upside down.

The inlet portion 46 has a trapezoidal shape protruding from the front skirt guard 40 on the upper floor, and an elliptical inlet opening 102 along the outer diameter of the handrail belt 38 is formed in the front portion thereof. An inlet moving body 104 having a C-shaped vertical cross section, which is larger than the handrail belt and smaller than the inlet opening 102, is arranged on the inner peripheral portion of the inlet opening 102. The inlet moving body 104 is slidable along the handrail rail 74, and the tip end portion of the inlet moving body 104 projects from the inlet opening 102.

The glass plate 72, the handrail rail 74, the handrail rail 74, and the handrail belt 38 penetrate the rail opening 108 and the inlet opening 102, and the handrail belt 38 moves inside the front skirt guard 40. On the other hand, the lighting device 70 fixed to the handrail rail 74 also penetrates the lighting opening 110 and penetrates into the front skirt guard 40.

The inlet portion 48 of the front skirt guard 42 on the lower floor has the same structure as the inlet portion 46, and the lighting device 70 has penetrated into the front skirt guard 42.

In the front skirt guard 40 on the upper floor, the power supply cable 100 extending from the LED substrate 86 arranged in the space 96 of the lighting device 70 is connected to the control unit 50 in the machine room 14 from the inside of the front skirt guard 40. It is wired.

The LED substrate 86 has a predetermined length, and is formed longer than the length of the cover support portion 92 and the cover 84 from the lower floor to the upper floor. Therefore, when the lighting device 70 is inserted into the space 96 and is inserted from the upper floor to the lower floor, a slight length is left over in the LED substrate 86, so that the length is inside the front skirt guard 42 on the lower floor. It is adjusted by the length of a certain LED board 86, or by the length of the LED board 86 inside the front skirt guard 40 on the upper floor. At this time, since the LED board 86 is slidable inside the space 95, the maintenance staff simply pulls and slides the LED board 86 to match the length of the LED board 86 inside the front skirt guard 42 on the lower floor. , The length of the LED board 86 inside the front skirt guard 40 on the upper floor can be easily adjusted.

(4) Effect According to the present embodiment, when the lighting device 70 is attached to the handrail rail 74, the cover support portion 92 is screwed to the lower surface plate 78 of the handrail rail 74 with a screw 93, and then the LED. After arranging the substrate 86, the cover 84 is attached. In this case, since the cover 84 is provided with a pair of left and right claws 90, 90, the cover 84 can be attached only by engaging the pair of left and right flange portions 94, 94 of the cover support portion 92. On the contrary, when removing the cover 84, it is sufficient to first remove the cover 84, remove the LED substrate 86, and then remove the cover support portion 92 from the lower surface plate 78 of the handrail rail 74.

Further, since the lighting device 70 has a structure of being attached to the lower surface plate 78 of the handrail rail 74, the maintenance staff can easily reach the position of the attachment work, and the work can be improved.

Further, since the wiring of the LED board 86 only connects the cable 100 protruding from the end of the LED board 86 to the power supply, the wiring work can be simplified.

Further, since the LED board 86 is provided on the handrail rail 74 from the front skirt guard 42 on the lower floor to the front skirt guard 40 on the upper floor, it is not necessary to adjust the position of the LED 88 even if the position of the LED board 86 shifts. ..

Further, the length of the LED board 86 is determined according to the length of the escalator 10, and the surplus LED board 86 can be hidden in the front skirt guard 40 or the front skirt guard 42, so that installation is easy.

Further, since the lower part of the handrail rail 74 is illuminated by the LED 88 and the LED 88 also emits light along the semicircular portions 36a and 36b of the balustrade 36, the design of the escalator 10 can be enhanced.

Further, the handrail rail 74 can be inserted into the inlet portions 46 and 48 and fixed with the lighting device 70 attached.

Further, even in the existing escalator 10, the lighting device 70 can be easily attached to the rail 74.
