  As shown in FIGS. 3 to 5, the supporting members 100 arranged in parallel are formed of the mounting portion 104 made of steel material having a U-shaped cross section and the upper surface portion 106 provided on the upper portion of the mounting portion 104. It is formed. As shown in FIG. 5, the placement unit 104 includes a side plate 108, an upper plate 110 extending outward from an upper end portion of the side plate 108, and a lower plate 112 extending outward from a lower end of the side plate 108. It consists of A plate-like upper surface portion 106 is fixed to the upper surface of the upper plate 110 by welding. Non-slip irregularities 114 are formed on the upper surface of the upper surface portion 106 by etching.

  As shown in FIG. 3A and FIG. 7, the step board 102 includes a frame-shaped frame member 116 having a rectangular planar shape, a face plate 118 fixed by welding on the surface of the frame member 116, and the frame member 116. It is comprised from the backplate 120 fixed by welding to the back. The frame member 116 is formed of a front frame 122, a rear frame 124, a left frame 126, and a right frame 128. As shown in FIG. 5, the surface plate 118 is formed of two layers of an outer surface plate 130 on which the unevenness 131 is formed by etching and a substrate 132 supporting the outer surface plate 130. Similarly, the back plate 120 is formed of two layers of an outer surface plate 134 and a substrate 136, and the upper surface of the outer surface plate 134 is formed with non-slip unevenness 135 by etching.

  As shown in FIG. 4, a rotary shaft 138 penetrates in the left-right direction through the pair of left and right support members 100 and the tread plate 102. Specifically, as shown in FIGS. 4 and 7, the rotary shaft 138 penetrates the center in the front-rear direction of the left frame 126 and the right frame 128 of the frame member 116 and the center in the vertical direction. Further, in the support member 100 as well, the center of the side plate 108 in the front-rear direction and the center in the vertical direction are penetrated. Thereby, the step board 102 is rotatable between the pair of left and right support members 100.

  As shown in FIG. 5, bolt holes 140 pass through the front and rear portions of the side plate 108 of the right side support member 100, and bolt holes 142 pass through the right frame 128 of the frame member 116 corresponding to this position. The nut 144 is fixed to the inner surface. Similarly, in the support member 100 on the left side, bolt holes 140 pass through the front and rear portions of the side plate 108, and bolt holes 142 and nuts 144 are respectively formed on the front and rear portions of the left frame 126 of the frame member 116 corresponding to this position. It is provided. Then, as shown in FIG. 3, when the tread plate 102 is horizontally disposed between the pair of left and right support members 100, the bolt 146 is screwed into the bolt hole 140, the bolt hole 142, and the nut 144 two each. Then, the rotation of the step board 102 is stopped.

  The other two landing plates 342 and 343 have the same structure as the landing plate 341. Also, on the upper floor side, a plurality of passenger boards 32 having the same structure are provided.

(3) Usage method of the boarding plates 341 to 343 Although the usage method of the boarding plates 341 to 343 will be described, the boarding plate 341 will be described as a representative.

  First, as shown in FIGS. 3A and 3B, the tread plate 102 is fixed between the pair of left and right support members 100 with four bolts 146. At this time, the surface plate 118 is disposed so as to be the upper surface.

  Next, as shown in FIG. 3 (b), the pair of left and right support members 100 are horizontally mounted on the pair of left and right upper frame members 70 constituting the truss 12.

  Next, as shown in FIG. 2, the other landing plates 342 and 343 are similarly placed on the upper frame member 70.

  Thereby, the operation of the escalator 10 is started with the face plate 118 at the top. Then, when the escalator 10 is operated and a passenger passes over the landing plates 341 to 343, the etched portion of the outer surface plate 130 of the face plate 118 is worn or damaged by the shoes and luggage of the passenger. At that time, in order to ensure the safety of the passenger, the worker once removes the board 341 from the upper frame member 70 at the time of inspection and maintenance.

  Next, remove the four bolts 146 from the board 341.

  Next, as shown in FIG. 6, the tread plate 102 is rotated by 180 degrees about the rotation shaft 138, and the back plate 120 is turned to the upper surface.

  Next, the tread plate 102 is again fixed to the pair of left and right support members 100 with four bolts 146.

  Next, as shown in FIG. 3B, the passenger plate 341 is placed on the pair of upper frame members 70 again. As a result, the beautiful back plate 120 with the unevenness 135 not worn away, which has not been used up to now, becomes the top surface, and it is possible to prevent the passenger from falling over.

(4) Effects According to the present embodiment, even if the unevenness of the surface plate 118 is worn or damaged by the operation of the escalator 10, the back plate 120 becomes the upper surface by rotating the tread plate 102 by 180 °. There is no unevenness and the passengers can be prevented from falling. By this, although it was necessary to replace the board itself when it was worn conventionally, in the present embodiment, it is only necessary to rotate the step board 102, and it is possible to achieve a long life.

  Moreover, since the unevenness | corrugation 114 is provided also in the upper surface of the supporting member 100, a passenger does not fall.

  Further, since the lower plate 112 of the support member 100 is not provided with the unevenness, it can be stably placed on the upper frame member 70.

  Moreover, when rotating the step board 102, only the four bolts 146 need to be removed, and the operation is easy.

There is. A plurality of stud bolts 170 are fixed to the opposite surface of the face plate 118 so as to protrude therefrom. The positions at which the stud bolts 170 are provided correspond to the positions of the bolt holes 156 and the bolt holes 166 of the front fixing member 150 and the rear fixing member 160. As shown in FIGS. 8 and 9, a plurality of stud bolts 172 are provided on the opposite surface of the back plate 120. The positions where the stud bolts 172 are provided also correspond to the positions of the bolt holes 156 and the bolt holes 166 of the front fixing member 150 and the positions of the bolt holes and the bolt holes of the rear fixing member 160.

  Further, in the present embodiment, the upper surface portion 106 is attachable to and detachable from the mounting portion 104 of the pair of left and right support members 100. In order to realize this, as shown in FIG. 9, a bolt hole 174 vertically penetrates through the upper plate 110 of the mounting portion 104, and a nut 176 is provided at this position. Then, a stud bolt 178 protrudes from the lower surface of the upper surface portion 106, passes through the bolt hole 174, and is fixed by a nut 176.

  As described above, not only can the tread plate 102 be rotated to use the front plate 118 and the back plate 120 as the landing plate 341 of the present embodiment, but if the front plate 118 is worn, the frame 116 to the front plate 118 Can be removed and replaced with a new face plate 118. Also, the back plate 120 can be replaced similarly. Furthermore, the upper surface portion 106 of the support member 100 can also be replaced. Therefore, the life can be further extended compared to the conventional board.

Modified example

  Although the bolt 146 is used to stop the rotation of the step board 102 relative to the support member 100 in the above embodiment, other fixing means such as a spring-type lever may be used instead.

  Moreover, in the said embodiment, although applied and demonstrated to the escalator 10, it may replace with this and may apply to the moving sidewalk.
