That is, the movable riser 11 is provided, for example, in a range between the left frame 8 and the right frame 8. For example, a fixed normal riser is provided in a range outside the left frame 8 and the right frame 8. In step 7 in the state shown in FIG. 2, the rear end of the movable riser 11 is, for example, in a position aligned with the rear end of a normal riser.

  FIG. 4 is a second side view of the steps in the first embodiment. FIG. 4 shows the right side of step 7. The right side in FIG. 4 is the front, and the left side in FIG. 4 is the back.

  FIG. 4 shows a state in which a force is applied to the movable riser 11 such that a portion below the rotating shaft 12 moves toward the center side of the tread plate 10. The said force is a force which pushes the lower part of the movable riser 11 forward, for example. The force is against the force that the spring 13 pulls the lower end of the stopper portion 11a downward. In the state shown in FIG. 4, the upper end and the front end of the stopper portion 11 a protrude upward from the tread board 10.

  FIG. 5 is a second top view of the step in the first embodiment. FIG. 5 is a top view of step 7 in the state shown in FIG. The lower side in FIG. 5 is the front, and the upper side in FIG. 5 is the rear. In step 7 in the state shown in FIG. 4, the rear end of the movable riser 11 projects rearward from the rear end of a normal riser.

  FIG. 6 is a side view showing the operation of the movable riser in the first embodiment. FIG. 6 shows the right side of the plurality of moving steps 7.

  As shown in FIG. 6, the step board 10 in step 7 that is moving along the inclined portion of the escalator pushes the lower part of the movable riser 11 in the other step 7 adjacent to the front. That is, when the step 7 is moving on the inclined portion of the escalator, the stopper portion 11 a of the step 7 protrudes upward from the tread board 10.

  As shown in FIG. 6, the step board 10 in step 7 moving in the horizontal part of the escalator pushes forward the stopper part 11 a of another step 7 adjacent to the front. That is, when the step 7 is moving on the horizontal portion of the escalator, the stopper portion 11 a of the step 7 does not protrude upward from the tread plate 10.

  Thus, the movable riser 11 operates as the step 7 moves. The movable riser 11 operates both when the escalator is running up and down.

  FIG. 7 is an enlarged top view of steps in the first embodiment. FIG. 7 shows a part of the tread board 10 and the stopper portion 11a in the state shown in FIGS. The right side in FIG. 7 is the front, and the left side in FIG. 7 is the back.

  As shown in FIG. 7, the tread 10 has a plurality of tread-side cleats 14 formed along the front-rear direction. The plurality of tread board-side cleats 14 are arranged along the left-right direction. The plurality of tread plate-side cleats 14 include those having a relatively long length in the front-rear direction and those having a short length. The plurality of tread board-side cleats 14 are, for example, long and short ones that are arranged alternately.

  As shown in FIG. 7, the stopper portion 11a has a plurality of stopper-side cleats 15 formed along the front-rear direction. The plurality of stopper-side cleats 15 are arranged along the left-right direction. The plurality of stopper-side cleats 15 include those having relatively long and short lengths in the front-rear direction. The plurality of stopper-side cleats 15 are, for example, long ones and short ones arranged alternately.

  As shown in FIG. 7, the long tread-side cleat 14 is adjacent to the short stopper-side cleat 15 in the front-rear direction. The short tread side cleat 14 is adjacent to the long stopper side cleat 15 in the front-rear direction. The long tread side cleat 14 enters the gap between the long stopper side cleats 15 in the left-right direction. The long stopper-side cleat 15 enters a gap between the long tread-side cleats 14 in the left-right direction.

  FIG. 8 is a first enlarged perspective view of steps in the first embodiment. FIG. 9 is a second enlarged perspective view of steps in the first embodiment. FIG. 8 shows a part of the tread board 10 and the stopper portion 11a in the state shown in FIGS. FIG. 9 shows a part of the tread board 10 and the stopper portion 11a in the state shown in FIGS.

  When step 7 is moving on the horizontal portion of the escalator, the stopper-side cleat 15 does not protrude from the upper end of the tread board-side cleat 14 as shown in FIG. On the other hand, when the step 7 is moving along the inclined portion of the escalator, the upper end of the stopper side cleat 15 protrudes from the upper end of the tread plate side cleat 14 as shown in FIG.

  In the first embodiment, the frame 8 supports the tread board 10 from below. The movable riser 11 has a stopper portion 11 a adjacent to the end portion of the tread plate 10 in the front-rear direction, is supported by the frame 8 via the rotation shaft 12 along the left-right direction, and rotates around the rotation shaft 12. The stopper portion 11a projects upward from the tread board 10. If the stopper portion 11a of step 7 protrudes upward, for example, the carry bag or the like placed in step 7 is prevented from sliding down. That is, step 7 in the first embodiment is a passenger conveyor step having a sliding prevention function. For this reason, according to the first embodiment, it is possible to prevent slipping of luggage or the like placed on the tread board 10 without restricting the standing position of the passenger on the tread board 10. As a result, passenger comfort and safety of the passenger conveyor can be improved.

  In the first embodiment, when the movable riser 11 is rotated so that the portion below the rotation shaft 12 moves toward the center of the tread 10 viewed from the left-right direction, the stopper portion 11 a is more than the tread 10. Is also projected upward. That is, for example, when the step 7 is moving on the inclined portion of the escalator, the stopper portion 11a protrudes upward when the lower portion of the movable riser 11 is pushed by the adjacent step 7. For this reason, according to Embodiment 1, the stopper part 11a can be protruded upwards with the driving | operation of a passenger conveyor, without requiring separate motive power.

  In the first embodiment, when the movable riser 11 is rotated so that the portion above the rotating shaft 12 moves toward the center of the tread viewed from the left-right direction, the stopper portion 11a is above the tread 10 It will be in a state where it does not protrude. That is, for example, when the step 7 is moving on the horizontal portion of the escalator, the stopper portion 11a is retracted downward when the upper portion of the movable riser 11 is pushed by the adjacent step 7. For this reason, according to Embodiment 1, the stopper part 11a can be accommodated with the driving | operation of a passenger conveyor, without requiring separate motive power.

  In the first embodiment, one end of the spring 13 is attached to the movable riser 11, the other end is attached to the frame 8, and the upper part of the rotating shaft 12 is directed toward the center side of the tread 10 viewed from the left-right direction. A force is applied to the movable riser 11 so as to move. That is, the spring 13 forcibly accommodates the stopper portion 11a downward in the horizontal portion of the escalator. For this reason, according to Embodiment 1, it can prevent reliably that the stopper part 11a which protruded upwards rather than the tread board 10 interferes with the comb of the entrance / exit.

  In the first embodiment, at least a part of the tread-side cleat 14 enters the gap between the stopper-side cleats 15. At least a part of the stopper-side cleat 15 enters a gap between the tread board-side cleats 14. For this reason, according to Embodiment 1, the opening part of the stopper part 11a and the tread board 10 which protruded upwards rather than the tread board 10 does not become large. As a result, it is possible to make it difficult for objects to be caught between the stopper portion 11a and the rear end of the tread board 10.

  In the first embodiment, the stopper portion 11a is formed of a material having elasticity, for example. In this case, it is possible to make the stopper portion 11a difficult to break. Moreover, in this case, it is possible to easily remove the object sandwiched between the stopper portion 11a and the rear end of the tread board 10.

  In Embodiment 1, the stopper part 11a exhibits a color different from the tread board 10, for example. In this case, by making the stopper portion 11a stand out, it is possible to alert the passengers not to go.

  In the state where the stopper portion 11a protrudes upward from the step board 10, the angle formed by the front end of the stopper side cleat 15 with respect to the upper end of the step board side cleat 14 is, for example, a right angle as shown in FIG. The angle may be an acute angle or an obtuse angle. When the angle is an acute angle, for example, it is possible to further prevent the luggage placed on the tread board 10 from sliding down. When the said angle is an obtuse angle, a passenger can make it difficult to hit the stopper part 11a, for example.
