A handrail rail 39 is provided on the upper part of the balustrade 36, and the 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. The skirt guard 44 is provided at the lower side of the balustrade 36, and the step 30 runs 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 skirt guard 44 includes a plurality of skirt guard panels (hereinafter simply referred to as “panels”) 70. The panel 70 is detachably attached to a mounting member (not shown) provided on the upper portion of the truss 12 in a vertical direction. The panel 70 is made of metal, and the surface thereof is coated so that the step 30 can easily move, and the friction coefficient (dynamic friction coefficient) of the surface is set to μ0.

  The handrail belt 38 enters the front skirt guard 40 from the inlet 46 on the upper floor side, and is passed over the handrail drive sprocket 27 through the guide roller group 64, and then the skirt through the guide roller group 66. It moves in the guard 44 and appears outside the front skirt guard 42 from the inlet 48 on the lower floor side. The handrail belt 38 moves in synchronization with the step 30 as the handrail drive sprocket 27 rotates together with the drive sprocket 24. The rotating handrail driving sprocket 27 has a pressing member 68 for pressing the traveling handrail belt 38.

(2) Step 30
Next, the step 30 will be described with reference to FIG. As shown in FIG. 2, the step 30 includes a pair of left and right step frames 303, 303, a cleat surface 304 formed on the upper surface of the step frame 303, and a riser surface formed on the rear surface of the step frame 303. The step frame 303, the cleat surface 304, and the riser surface 305 are integrally formed by aluminum die casting.

  A pair of left and right front wheels 301, 301 are rotatably provided at the front end portion of the step frame 303. A pair of left and right rear wheels 302 and 302 are rotatably provided at the rear end of the step frame 303 and below the riser surface 305.

(3) Structure near the entrance / exit As shown in FIGS. 2 and 3, the vicinity of the entrance / exit on the lower floor side will be described. As shown in FIGS. 2 and 3, the comb-like comb 62 is provided at the front end of the lower floor board 34 as described above. Panels 70 are provided on the left and right sides of the comb 62. A high friction area 72 is provided near the tip of the comb 62, that is, on the upper floor side, as shown in FIG. A plurality of these high friction regions 72 are formed on the panel 70 at intervals along the front-rear direction. The high friction region 72 has a rectangular shape, and is inclined from the vertical direction so that the upper part is closer to the comb 62 and the lower part is away from the comb 62. Further, the upper end portion of the high friction region 72 is provided at a position protruding from the cleat surface 304 of the step 30 that moves horizontally, and the protruding upper end portion extends from a rectangular portion to a semicircular portion. The lower end portion of the rectangular high-friction region 72 also has a semicircular portion extending from the rectangular portion. The friction coefficient of the high friction region 72 is μ2. The high friction area 72 is made of a rubber plate and is attached to the panel 70 with an adhesive.

  There is a low friction region 74 between adjacent high friction regions 72. The low friction region 74 uses the surface of the panel 70 as it is, and the friction coefficient μ1 of the low friction region 74 is the same as the friction coefficient μ0. Then, there is a relationship of μ2> μ1 = μ0.

  In the above description, although explained on the lower floor side, as shown in FIG. 1, a high friction area 72 and a low friction area 74 are also provided in the vicinity of the tip of the comb 60 on the upper floor side.

(4) Effects According to the present embodiment, the high friction regions 72 and the low friction regions 74 are alternately formed, and the high friction regions 72 are formed so as to be inclined so as to approach the comb 62 toward the upper side. As shown in FIG. 3, even if the skirt of the passenger's skirt A riding on the descending step 30 and approaching the entrance / exit is sandwiched between the panel 70 and the step 30, the high friction region 72 and the low friction region 74 Since the high friction region 72 and the low friction region 74 are inclined and the upper end portion of the high friction region 72 protrudes from the step 30, the skirt of the skirt B and the skirt C of FIG. As shown by the hem, it moves obliquely upward and is reliably pushed upward, so that the skirt hem is not sandwiched between the panel 70 and the comb 62.

  Moreover, since the rubber plate is affixed on the panel 70 in the high friction region 72 and the surface of the panel 70 is used as it is in the low friction region 74, there is no protruding portion from the panel 70, and passengers do not collide.

(5) Modified Example In the above embodiment, the high friction region 72 is formed of a rubber plate, but instead, a coating liquid having a friction coefficient μ2 may be applied to the panel 70.

  Moreover, in the said embodiment, although the surface of the panel 70 was used as it is for the low friction area | region 74, it may replace with this and you may paint the coating liquid of friction coefficient (micro | micron | mu) 1.

  Moreover, although the said embodiment demonstrated the escalator 10, it may replace with this and the walk side which moves.

  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.
