As shown in FIG. 2, the notch portion 70 is preferably formed at the center in the width direction of the first surface plate 42. As shown in FIGS. 5 and 6, the first back member 52 on the back side of the first surface plate 42 is also formed with a notch 53 at a location overlapping the notch 70 in the vertical direction.

  As shown in FIGS. 5 and 6, the boarding / alighting plate 40 is provided with a rod-like member 72 that straddles the notch 70. Therefore, as shown in FIG. 6, the rod-like member 72 appears in the notch 70 in plan view. In this embodiment, the rod-shaped member 72 extends in the width direction of the boarding / alighting plate 40. The cross-sectional shape of the rod-like member 72 in the front-rear direction may be a polygon such as a quadrangle, but is a circle in this embodiment.

  The rod-like member 72 is fixed to the first surface plate 42 or the first back member 52 by welding or the like. In the present embodiment, as shown in FIGS. 5 and 6, the first back member 52 is extended to locations on both sides in the width direction of the notch 70, and a rod-like member 72 is formed on the lower surface of the extended portion. It is fixed.

  The cutout portion 70 of the first surface plate 42 is closed by a lid 74 covered from above. As shown in FIG. 5, when the cutout portion 70 is closed by the lid 74, the upper surface of the lid 74 and the upper surface of the first surface plate 42 form the same plane. This plane is the user's walking surface. Further, when the cutout portion 70 is closed by the lid 74, the end portion 73 of the lid 74 outside the escalator (in the direction of arrow D in FIGS. 5 and 6) and the edge metal 65 that is an adjacent member of the lid 74, A slight gap 79 is formed between them.

  As shown in FIG. 5, a holding portion 75 that holds the rod-like member 72 by being fitted to the rod-like member 72 is provided on the back side of the lid 74. When the cutout portion 70 is closed by the lid 74, the holding portion 75 holds the rod-shaped member 72. In the present embodiment, the holding portion 75 holds the rod-like member 72 with the rod-like member 72 extending in the width direction of the boarding / alighting plate 40 sandwiched from both sides in the front-rear direction.

  The cross-sectional shape of the holding part 75 in the front-rear direction is substantially C-shaped. Further, as described above, the rod-shaped member 72 is a rod-shaped member having a circular cross-sectional shape in the front-rear direction. Therefore, the lid 74 is rotatable with the rod-shaped member 72 as the rotation axis while holding the rod-shaped member 72 with the holding portion 75.

  The holding portion 75 is provided so as to protrude downward near the center of the lid 74 in the front-rear direction. An inclined surface 76 is provided on the back side of the lid 74 so that the lid 74 becomes thicker in the vertical direction from the end 73 of the lid 74 outside the escalator toward the holding portion 75. The inclined surface 76 is inclined with respect to the upper surface of the lid 74.

  The holding portion 75 and the inclined surface 76 having the above characteristics may be provided at one place of the lid 74 (for example, a portion from one end to the other end of the lid 74 in the width direction) or in the width direction of the lid 74. It may be provided at a plurality of locations (for example, both side portions of the lid 74 in the width direction).

  The material of the lid 74 is, for example, resin or aluminum. The material of the lid 74 is preferably the same as the material of the first surface plate 42.

  As shown in FIGS. 5 and 6, a protrusion 78 projecting downward from the lid 74 is provided on the edge metal 65 outside the escalator from the lid 74. The protrusion 78 prevents the escalator outer portion of the lid 74 from falling down by hitting the lower surface of the escalator outer portion of the lid 74. As shown in FIG. 5, it is desirable that the protrusion 78 has already hit the lid 74 when the lid 74 closes the notch 70.

  The protrusion 78 is provided at a place other than the center of the lid 74 in the width direction. For example, as shown in FIGS. 5 and 6, two protrusions 78 are provided at locations on both sides of the lid 74 in the width direction.

  Note that the projection 78 that hits the lower surface of the lid 74 may be present outside the escalator below the rod-like member 72 under the lid 74, and not the edge metal 65 but the lower surface or the first back surface of the first surface plate 42. It may be fixed to the member 52.

  In addition, the protrusion which hits the lower surface of the lid | cover 74 in this way is not provided in the place of the step 20 side (arrow E side in FIG. 5, FIG. 6) from the rod-shaped member 72. FIG.

  The lid 74 may be designed such that the portion outside the escalator with respect to the rod-shaped member 72 serving as the rotation shaft is heavier than the portion on the step 20 side with respect to the rod-shaped member 72. For example, as shown in FIG. 5, the portion outside the escalator from the rod-shaped member 72 serving as the rotation shaft is designed to be longer in the front-rear direction or thicker in the vertical direction than the portion on the step 20 side from the rod-shaped member 72. It may be heavier. Accordingly, even if there is no protrusion that prevents the portion on the step 20 side of the lid 74 from descending from the rod-like member 72, the portion on the step 20 side of the lid 74 from the rod-like member 72 is light so that it is difficult to fall downward.

  The notched portion 70 and the lid 74 having the above characteristics are provided on both the upper floor boarding board 40 and the lower floor board 40.

6). How to Remove the Boarding / Exiting Plate 40 The method for removing the boarding / exiting plate 40 will be described using an example in which the handrail belt attaching / detaching tool 80 shown in FIG. As shown in FIG. 7, the handrail belt attaching / detaching tool 80 has a hook-shaped hook portion 81. The handrail belt attaching / detaching tool 80 is a tool used for attaching / detaching the handrail belt 24 at the time of installation or maintenance inspection of the escalator 1.

  When removing the boarding / alighting plate 40, first, the operator inserts the tip of the hook portion 81 of the handrail belt attaching / detaching tool 80 into the gap 79 (see FIG. 5) between the end portion 73 of the lid escalator 73 and the rim 65. And gently lift the outer part of the escalator of the lid 74 (FIG. 8A). Next, the operator inserts the tip of the hook portion 81 of the handrail belt attaching / detaching tool 80 into the notch 70 while sliding the inclined surface 76 on the back side of the lid 74 (FIG. 8B). . Then, the lid 74 rotates around the rod-shaped member 72 as a rotation axis, and the portion of the lid 74 outside the escalator is lifted.

  Next, the operator grasps the raised portion of the lid 74 and removes the lid 74 from the rod-shaped member 72 (FIG. 8C). Then, the rod-like member 72 appears in the cutout portion 70 of the first surface plate 42 in plan view.

  Next, the worker hooks the hook portion 81 of the handrail belt attaching / detaching tool 80 on the rod-like member 72 (FIG. 8D). Then, the operator lifts the first surface plate 42 by pulling the rod-shaped member 72 with the handrail belt attaching / detaching tool 80 (FIG. 8E), and removes the first surface plate 42.

  After removing the first surface plate 42, the operator removes the second surface plate 44 and the third surface plate 46 by hand. The operator can grasp the portion of the second surface plate 44 on the first surface plate 42 side by removing the first surface plate 42, so that the second surface plate 44 can be removed without using a tool or the like. . Similarly, the operator can remove the third surface plate 46 without using a tool or the like.

  In addition, when an operator removes the 1st surface plate 42, the 2nd surface plate 44, and the 3rd surface plate 46, naturally the 1st back member 52, the 2nd back member 54, and the 3rd back member fixed to them. 56 is also removed.

  The operator can perform the above-described work using another tool such as a driver instead of the handrail belt attaching / detaching tool 80. For example, the operator may put the driver in the gap 79 and lift the portion of the lid 74 outside the escalator using the driver as it is, and remove the lid 74 from the rod-shaped member 72. Then, after removing the lid 74 from the rod-shaped member 72, the operator may remove the first surface plate 42 by holding the rod-shaped member 72 with pliers and pulling it up.

7). Effect In the present embodiment, as described above, the notch portion 70 is formed in the first surface plate 42 of the boarding / alighting plate 40, and the rod-like member 72 is provided across the notch portion 70. Therefore, one operator can hook the tool on the rod-like member 72 to pull up the first surface plate 42 and remove the first surface plate 42. This work can be performed not by a dedicated tool but by a common tool used for maintenance and inspection of the escalator 1, such as a handrail belt attaching / detaching tool 80 or pliers.

  Here, since the notch 70 is formed in the center of the first surface plate 42 in the width direction, the boarding / alighting plate 40 can be easily removed by one operator.

  In addition, since the lid 74 that closes the notch portion 70 has the holding portion 75 and the holding portion 75 holds the rod-shaped member 72, the lid 74 is difficult to come off. Further, the operator can easily lift the portion of the lid 74 outside the escalator by rotating the lid 74 with the rod-shaped member 72 as the rotation axis, and can easily lift the lid 74 by grasping the lifted portion. Can be removed.

  In addition, since there is a projection 78 that hits the lid 74 at a location outside the escalator below the rod-like member 72 under the lid 74, the user may step on that portion by stepping on the portion of the lid 74 outside the escalator. Can be prevented. Further, since the gap 79 is formed between the end portion 73 of the lid 74 outside the escalator and the edge metal 65 adjacent to the lid 74 in a state where the cutout portion 70 is closed by the lid 74, the operator However, it is easy to start removing the lid 74 by inserting a tool into the gap 79.

  In addition, since the inclined surface 76 is provided on the lower surface of the lid 74 so that the lid 74 becomes thicker from the end portion 73 on the outer side of the escalator toward the holding portion 75, the operator moves the tool along the inclined surface 76. The lid 74 can be easily opened while sliding.

8). Modification Examples Various modifications, substitutions, omissions, and the like can be made to the above embodiments without departing from the spirit of the invention.

  FIG. 9 shows a boarding board 140 according to a modified example. In FIG. 9, the same parts as those in the above embodiment are given the same reference numerals as those in the above embodiment. The first surface plate 142 of the boarding / alighting plate 140 does not have the notch 70 at the end of the first surface plate 42 in the above embodiment, but instead has a through-hole 170 that penetrates the first surface plate 142 up and down. Is formed. It is desirable that the through hole 170 is also formed in the center of the first surface plate 142 in the width direction. The through-hole 170 is formed, for example, at a location outside the escalator from the center in the front-rear direction of the first surface plate 142. The through-hole 170 is closed by a lid 74 having the same structure and material as in the above embodiment (FIG. 9 shows a state where the lid 74 is removed). When the through hole 170 is closed by the lid 74, a slight gap is formed between the end portion 73 (see FIG. 8 and the like) of the lid 74 on the escalator and the first surface plate 142 that is an adjacent member of the lid 74. It is formed.

  In this modification, the same rod-like member 72 as that in the above embodiment is provided across the through hole 170. The lid 74 is attached to the first surface plate 142 by holding the rod-like member 72 with the holding portion 75. If the cross-sectional shape of the rod-shaped member 72 is circular, the lid 74 can be rotated about the rod-shaped member 72 as a rotation axis.

  A protrusion 178 is provided at a location outside the escalator from the rod-shaped member 72 of the through hole 170. The protrusion 178 is fixed to the lower surface of the first surface plate 142. Like the projection 78 in the above-described embodiment, the projection 178 hits the lower surface of the portion of the lid 74 outside the escalator, thereby preventing the portion of the lid 74 outside the escalator from falling down.

  The boarding board 140 of this modified example can also be removed by one operator by hooking a tool on the rod-like member 72 to pull up the first surface board 142 and removing the boarding board 140.
