A plurality of steps 30 are attached to the pair of left and right step chains 28, 28 at equal intervals. When the motor 20 rotates, the front wheel 301 of the step 30 travels on a guide rail (not shown) fixed to the truss 12, and the rear wheel 302 travels on the guide rail 25 fixed to the truss 12.

  On the left and right sides of the truss 12, a pair of left and right balustrades 36, 36 are erected. A handrail rail 39 is provided above the balustrade 36, and an endless handrail belt 38 moves along the handrail rail 39. A front skirt guard 40 on the upper floor side is provided in the lower front part on the upper floor side of the balustrade 36, and a front skirt guard 42 on the lower floor side is provided in the lower front part on the lower floor side. Inlet portions 46 and 48, which are entrances and exits of the handrail belt 38, protrude from each other.

  A skirt guard 44 is provided at the lower side of the balustrade 36, and the step 30 travels between the pair of left and right skirt guards 44, 44. Operation panels 52 and 56 and speakers 54 and 58 are provided on the inner side surfaces of the skirt guards 44 on the upper and lower floors, respectively.

The lower floor side entrance / exit board 34 is provided on the ceiling surface of the machine room 16 and is provided horizontally. A comb-like comb 60 is provided at the front end of the upper floor board 32, and the step 30 enters the comb 60. A comb-like comb 62 is also provided at the tip of the lower floor board 34.

(2) Structure of Cleaning Device 70 Next, the structure of the cleaning device 70 will be described with reference to FIGS. The pair of left and right cleaning devices 70 includes a fixed shaft 72, a cylindrical member 74, and a cleaning member 76, respectively. The pair of left and right cleaning devices 70 are provided on the pair of left and right handrail belts 38, 38, respectively.

  The fixed shaft 72 is fixed horizontally to the truss 12 using a fixing bracket (not shown). The attachment position is below the traveling path of the handrail belt 38 at the lower part of the balustrade 36. As shown in FIG. 4, the fixed shaft 72 includes a large-diameter portion 78 and a small-diameter portion 80 via a stepped portion 77. The small diameter portion 80 is fitted with an inner ring 82a of a bearing 82 that is movable along the axial direction. The bearing 82 is arranged so as not to move to the large-diameter portion 78 at the position of the stepped portion 77, and conversely, is movable in the small-diameter direction. The small diameter portion 80 is provided with a coiled spring 84, one end of the spring 84 is fixed to one end of the small diameter portion 80, and the other end urges the bearing 82 toward the large diameter portion 78. A pair of left and right pins 88, 88 project from one end of the fixed shaft 72. In FIG. 4, the pair of pins 88 and 88 project vertically from one end of the fixed shaft 72, but the actual pin 88 projects in the front-rear direction. The reason described in FIG. 4 is to make the protruding state of the pin 88 easy to understand.

  In the cylindrical member 74, the outer ring 82b of the bearing 82 is fixed to the inner periphery. The position where the bearing 82 is attached is the center of the cylindrical member 74 in the axial direction. In the circumferential direction of one end of the cylindrical member 74, as shown in FIG. 3, convex portions 90 project at predetermined intervals, and concave portions 92 are provided therebetween, and these concave portions 92 and a pair of pins 88 are engaged. .

  The cleaning member 76 is made of a cylindrical sponge and is fixed to the outer periphery of the cylindrical member 74. On the outer peripheral surface of the cleaning member 76, a plurality of cleaning protrusions 86 protrude at predetermined intervals along the radial direction and the axial direction. The plurality of cleaning convex portions 86 of the cleaning member 76 come into contact with the flat portion of the handrail belt 38.

(3) Operational State of Cleaning Device 70 Next, the operational state of the cleaning device 70 will be described with reference to FIGS. 3 and 4.

  First, as shown in FIG. 4, the spring 84 always presses the bearing 82 against the stepped portion 77, and the pin 88 is positioned in the concave portion 92 between the convex portions 90, 90 of the cylindrical member 74. As shown in FIG. 3, when the handrail belt 38 travels in one direction, the cleaning member 76 of the cleaning device 70 is in contact with the handrail belt 38, so that the cleaning member 76 and the cylindrical member 74 are moved together with the handrail belt 38. Rotate around the fixed shaft 72. As a result, the pin 88 gets over the convex portion 90 against the biasing force of the spring 84, and the pin 88 enters the adjacent concave portion 92 again by the biasing force of the spring 84. Therefore, when the cylindrical member 74 rotates, the cylindrical member 74 vibrates in the axial direction by the height of the convex portion 90. Thereby, the cleaning convex part 86 on the surface of the cleaning member 76 vibrates and cleans the surface of the handrail belt 38.

(4) Effects According to the present embodiment, the cleaning member 76 rotates and vibrates in the axial direction when the handrail belt 38 travels, so that the cleaning convex portion 86 on the surface of the cleaning member 76 becomes the handrail belt. Clean 38 surfaces.

  The cleaning device 70 includes a fixed shaft 72, a cylindrical member 74, a cleaning member 76, and a bearing 82. The number of parts is small, and the cost can be reduced.

  Moreover, the cleaning apparatus 70 should just be attached to the truss 12 of the existing escalator 10, and the cleaning apparatus 70 can be attached later. Also, the attachment position can be attached to each escalator 10 at the position most effective for cleaning.

(5) Modification Example Next, a modification example of the cleaning device 70 of the above embodiment will be described with reference to FIGS. 7 and 8.

  The difference between this modified example and the above embodiment is the structure of the circumferential portion of one end of the cylindrical member 74. In the above embodiment, the protrusions 90 are provided at predetermined intervals. Are provided at predetermined intervals. The pair of pins 88 protruding from the fixed shaft 72 fits into or protrudes from the groove 92, so that the cylindrical member 74 vibrates in the axial direction by the depth of the groove 92.

(6) Other Modifications In the above embodiment, the cleaning projections 86 are provided on the surface of the cleaning member 76 in the radial direction and the axial direction at predetermined intervals. Instead, a ring-shaped surface is provided on the surface of the cleaning member 76. Cleaning ridges may be provided along the axial direction at predetermined intervals.

  Moreover, in the said embodiment, although the cleaning member 76 was made from sponge, it may replace with this and the rubber-made cleaning member 76 may be sufficient. However, in order to prevent the surface of the handrail belt 38 from being damaged, the handrail belt 38 is formed of a softer rubber than the rubber of the handrail belt 38.

  Moreover, in the said embodiment, although the pair of pins 88 protruded in the front-back direction, it may replace with this and may protrude in an up-down direction. Further, the four pins 88 may be protruded in the up / down and front / rear directions every 90 °.

  In the said embodiment, although demonstrated applying to the escalator 10, you may replace with this and may apply to the moving sidewalk.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
