Hereinafter, an escalator 1 which is a passenger conveyor according to an embodiment of the present invention will be described with reference to FIGS. 1 to 9.

(1) Structure of Escalator 1 The structure of the escalator 1 will be described with reference to FIGS. 1 to 3.

As shown in FIG. 1, support angles 3 are provided at the front and rear ends of the truss 2 of the escalator 1. The pair of front and rear support angles 3 are respectively mounted on a frame 102 notched in the floor surface 101 of the upper floor of the building 100 and a frame 103 notched in the floor surface 101 of the lower floor of the building. Has been passed. The support angle 3 is covered with the mortar 104 and adjusted to the same height as the floor surface 101.

As shown in FIG. 1, a pair of left and right balustrades 8 and 8 are provided on the truss 2, and a plurality of steps 4 are arranged between the pair of left and right balustrades 8 and 8 so as to be movable in the front-rear direction. There is. A handrail belt 5 that moves in synchronization with the steps 4 is provided at the upper end of the balustrade 8. A machine room 6 is provided at an end portion on the upper floor side of the truss 2, and inside the machine room 6, a drive device and a control device (not shown) for moving the steps 4 and the handrail belt 5 are provided. ing.

As shown in FIG. 3, mounting members 7 are provided on the left and right sides of the upper portion of the truss 2 located on the upper surface of the machine room 6. As shown in FIG. 2, a boarding/alighting board 9 and a boarding/alighting board 10 are mounted on the pair of left and right mounting members 7, 7 in order from the step 4 side.

(2) Boarding board 10
Next, the structure of the boarding/alighting board 10 placed apart from the step 4 will be described. The boarding/alighting board 10 is first removed by a maintenance staff at the time of inspection.

As shown in FIG. 4, the boarding/alighting plate 10 has a rectangular substrate 12 made of a metal plate, and as shown in FIG. 5, the front wall 14 is downward from the step 4 side of the substrate 12, that is, from the front end portion of the substrate 12. The rear wall 15 is bent downward from the side opposite to the step 4 side, that is, from the rear end of the substrate 12. As shown in FIG. 9, the right side of the front wall 14 of the substrate 12 in the drawing is formed in a triangular shape so that the vertical dimension becomes shorter toward the right side, and the left side is also formed similarly although not shown. As shown in FIGS. 4 to 6, a plurality of (for example, three) reinforcing ribs 26 extending in the left-right direction are formed on the lower surface of the substrate 12.

As shown in FIG. 4, reinforcing members 16 and 16 are fixed to the left and right sides of the front wall 14 by bolts (not shown). Since the pair of left and right reinforcing members 16 and 16 are symmetrical, only the right side will be described. As shown in FIGS. 5 and 6, the reinforcing member 16 is formed by bending a metal plate, and includes a fixing portion 18 fixed to the front wall 14 by a bolt (not shown), and the fixing portion 18. The upper surface portion 20 is formed by bending the upper end forward, and the contact portion 22 is formed by bending the front end portion of the upper surface portion 20 downward. As shown in FIG. 9, a right end portion of the upper surface portion 20 and the contact portion 22 in the drawing is cut out by a cutout portion 23, and is formed to be shorter than the fixed portion 18. Similarly to the front wall 14, the fixing portion 18 of the reinforcing member 16 is also formed in a triangular shape so that the height decreases toward the right side.

The upper surface portion 20 of the reinforcing member 16 and the substrate 12 are formed on the same surface, and the decorative plate 24 is fixed thereon. The surface of the decorative plate 24 is engraved with irregularities for preventing passengers from slipping, and letters and numbers. The front end portion of the decorative plate 24 covers the upper surface portion 20 of the reinforcing member 16 partway, and the remaining upper surface portion 20 and the contact portion 22 are exposed.

As shown in FIGS. 4 and 7, support members 28 formed by bending a metal plate are attached in the front-rear direction on the lower surface of the substrate 12 and on both the left and right sides of the reinforcing rib 26. The height of the support member 28 is higher than that of the front wall 14 of the substrate 12, the fixed portion 18 and the contact portion 22 of the reinforcing member 16. This is because the pair of left and right support members 28, 28 are mounted on the pair of left and right mounting members 7, 7 provided on the upper portion of the truss 2.

Through holes 38 and 40 are opened in the center of the rear part of the decorative plate 24 and the substrate 12, as shown in FIG. A pulling screw 30 made of a flat screw is inserted into the through holes 38 and 40. A screw receiving portion 32 having a recess formed by bending a metal plate is fixed to the lower surface of the substrate 12 on which the lifting screw 30 is provided by bolts 34, 34. A screw hole 36 is provided at the bottom of the recess of the screw receiving portion 32. Then, the pulling-up screw 30 inserted from above the boarding/alighting plate 10 penetrates the through hole 38 of the decorative plate 24 and the through hole 40 of the substrate 12, and the two nuts 42 and 44 are provided in the screw receiving portion 32. It is attached and screwed into the screw hole 36.

The boarding/alighting board 10 on the lower floor side has the same structure as the upper floor side.

(3) Method for Removing Boarding Board 10 Next, a method for removing the boarding board 10 will be described. As shown in FIG. 6, when one maintenance worker removes the boarding/alighting plate 10, the maintenance screw 30 is loosened with a screwdriver or the like and removed from the screw hole 36. The pull-up screw 30 projects upward until the nuts 42 and 44 come into contact with the edge of the through hole 40. A jig 46 for pulling up the screw is attached to this protruding portion, and a maintenance person holds the pulling jig 46 and pulls up the rear part of the boarding/alighting board 10.

As shown in FIG. 3, the maintenance staff pulls up the rear part of the boarding/alighting board 10 with the lifting jig 46, and then drags the boarding/alighting board 10 toward the rear opposite to the step 4. At this time, as shown in FIG. 6, the decorative plate 24 is covered only up to the middle of the upper surface portion 20 of the reinforcing member 16, and the abutting portion 22 of the reinforcing member 16 is placed on the mounting member 7 when it is inclined. It abuts on the upper surface and shifts from this part as the starting point. Further, as shown in FIG. 9, the left and right ends of the front wall 14 of the substrate 12 and the fixing portion 18 of the reinforcing member 16 are formed in a triangular shape, so that the mounting member 7 and other members are slid rearward. be able to. Further, as shown in FIG. 6, the upper surface portion 20 and the abutting portion 22 are notched at the left and right ends by the notch portions 23, so that even at this position, they do not come into contact with other members on the left and right sides.

(4) Effect According to the present embodiment, even if one maintenance person holds the lifting screw 30 and pulls up the rear portion of the boarding/alighting board 10 and pulls it, the front end portion of the decorative plate 24 of the boarding/alighting board 10 is not damaged.

(5) Modification Example In the above embodiment, the upper floor and the lower floor are configured of two boarding plates, but the number of boarding boards is not limited to this, and three or more boarding plates are provided. It may be composed of the boarding/alighting board.

Although the above embodiment has been described by applying it to the escalator 1, it may be applied to a moving sidewalk instead.

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 their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the scope equivalent thereto.
