  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. The escalator 1 has a plurality of steps 4 that circulate between an entrance 2 on the lower floor and an entrance 3 on the upper floor. The escalator 1 can change the moving direction of the step 4 from the lower floor to the upper floor or from the upper floor to the lower floor. Here, the escalator 1 gets off from the entrance 2 on the lower floor where the step 4 is the landing side. The case of moving to the entrance / exit 3 on the upper floor which is the field side will be described.

  A boarding board 5 is provided at each of the entrances 2 and 3 on the upper and lower floors, and a comb 6 is provided at the front end of the boarding board 5.

  The step 4 includes a hollow support frame 7, a tread plate 8 fixed to the support frame 7, a pair of front wheels 9 attached to the support frame 7, and a pair of rear wheels 10 attached to the support frame 7. I have. The tread board 8 is a part on which the escalator user puts his / her foot. The tread board 8 is formed in an elongated shape in the front-rear direction, which is a direction along the moving direction of the step 4, and is slidably engaged with the comb 6. A groove 11 is formed.

  The step 4 is provided with a movable body 12 located on the rear end side in the moving direction of the step 4. As shown in FIG. 3, the movable body 12 is formed by a plurality of protrusions 13 and a connecting portion 14 that connects the plurality of protrusions 13. The plurality of protrusions 13 are disposed through the opening 15 formed on the bottom side of the groove 11 and on the rear end side in the moving direction of the step 4. The movable body 12 is provided so as to be movable between a protruding position where the tip of the protrusion 13 protrudes upward from the tread board 8 and a storage position where the tip of the protrusion 13 enters below the tread board 8. .

  Specifically, the storage position means that the tip of the protrusion 13 enters below the bottom surface of the groove 11 as shown by a solid line in FIGS. This is a position where interference with the comb 6 can be prevented when passing.

  Inside the support frame 7, an electric cylinder 16 that is an actuator for moving the movable body 12 between a protruding position and a storage position, and a control device 17 that controls the electric cylinder 16 are provided. The control device 17 is based on a control signal transmitted from a main control device (not shown) that controls the operation of the escalator 1, and a boarding / exiting plate in which a step 4 that circulates is provided at the boarding gate 2 on the landing side. When the lower side of 5 is passed, the electric cylinder 16 is driven to move the movable body 12 to the protruding position.

  When the movable body 12 moves to the protruding position, as shown in FIG. 3, the dimension “H” from the upper surface of the tread plate 8 to the tip of the protrusion 13 becomes several mm.

  The movable body 12 is moved to the projecting position after the step 4 passes the lower side of the boarding board 5 at the entrance 2 and then moves horizontally, and then the stage 4 obliquely moves toward the entrance 3 at the landing. This is done so that the movement ends before the movement starts.

  Note that when the step that has finished the oblique movement starts horizontal movement on the landing side, the electric cylinder 16 is driven in the reverse direction, and the movable body 12 moves to the storage position.

  The escalator 1 is provided with skirt guard panels 18 on both sides in a direction orthogonal to the moving direction of the steps 4. A speaker 19 is provided at a position near the entrances 2 and 3 in the skirt guard panel 18. From the speaker 19 at the boarding / exit gate 2 on the landing side, an announcement regarding the footrest position on the step board 8 of the step 4 is made, for example, “Please stand at a position where there is no step”.

  The skirt guard panel 18 is provided with a changeover switch 20 that is located in the vicinity of the landing entrance 2 on the landing side and can be switched between a first changeover position and a second changeover position. This change-over switch 20 switches the range in which the movable body 12 is positioned at the protruding position, and when switched to the first switching position, as described above, the range in which the movable body 12 is positioned at the protruding position is A range in which the step 4 horizontally moves on the platform 2 side of the landing and a range in which the step 4 moves obliquely toward the platform 3 on the landing. Moreover, when switching to the 2nd switching position, the range in which the movable body 12 is located in a protrusion position can be made into the range which the step 4 moves horizontally on the boarding / exiting gate 2 side of a landing.

  In such a configuration, when the escalator 1 is in operation, the step 4 moves horizontally for a certain section after passing under the boarding board 5 of the boarding entrance 2 and then toward the boarding board 3 on the landing side. To move diagonally.

  The electric cylinder 16 is driven after the step 4 passes the lower side of the boarding board 5 of the boarding gate 2 on the landing side, and the movable body 12 located at the accommodation position shown by the solid line in FIG. It moves toward the protruding position shown, and the tip of the protruding portion 13 protrudes upward from the upper surface of the tread plate 8 as shown by a two-dot chain line in FIGS. This moving operation is performed while the step 4 is moving horizontally.

  Therefore, when the escalator user who has ridden on the escalator 1 from the landing entrance 2 on the landing side puts his / her leg across the two steps 4 that are moving horizontally, the protrusion 13 that moves to the protruding position is the bottom of the foot. Therefore, the escalator user can be surely noticed that the foot is straddling the two steps 4. Thereby, it is possible to prompt the escalator user to move the foot placed on the two steps 4 onto one of the steps 4.

  In this way, when the escalator user moves his / her foot straddling the two front and rear steps 4 onto one of the steps 4, the step 4 starts to move obliquely and the two front and rear steps Even if there is a step between the four, it is possible to prevent an accident that the escalator user falls due to the occurrence of the step.

  In addition, at the entrance / exit 2 on the landing side, an announcement regarding the foot placement position on the step 4 is made from the speaker 19, for example, “Please stand at a position where there is no step”. Attention is paid to the loading position, and the foot 13 is further noticed by the protrusion 13 and the escalator user puts the foot on the two steps 4 on either one of the steps 4. Can be further encouraged to move to.

  By switching the changeover switch 20 and switching the changeover switch 20 to the first changeover position, the range in which the movable body 12 is located at the protruding position, the range in which the step 4 horizontally moves on the landing side, and the step 4 It can be set as the range which moves diagonally toward the entrance / exit 3 on the landing side. Further, by switching the changeover switch 20 to the second switching position, the range in which the movable body 12 is located at the protruding position can be set as the range in which the step 4 moves horizontally on the landing side.

  The original action of the movable body 12 is to prevent the escalator user from stepping on the two steps 4 positioned back and forth when the escalator user gets on the escalator 1. The range to be performed may be a range in which the step 4 moves horizontally on the landing side. However, the escalator user who walks on the step 4 of the escalator 1 by the changeover switch 20 is switched to the first switching position and the movable body 12 is positioned in the protruding position even in the range where the step 4 moves obliquely. Slip on the top can be prevented.

(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same component as the component demonstrated in 1st Embodiment, and the overlapping description is abbreviate | omitted.

  In the second embodiment, a control device 17a is provided instead of the control device 17, and an electric cylinder 16, a load detection unit 21, and a buzzer 22 serving as a notification unit are connected to the control device 17a. Has been.

  The load detection unit 21 detects a load acting on the movable body 12. The load acting on the movable body 12 is, for example, a load that acts when the escalator user is stepping on the movable body 12 moved to the protruding position.

  Similarly to the control device 17 of the first embodiment, the control device 17a is a step 4 that circulates and moves based on a control signal transmitted from a main control device (not shown) that controls the operation of the escalator 1. , The electric cylinder 16 is driven and the movable body 12 is moved to the protruding position when it passes under the boarding board 5 provided at the boarding gate 2 on the landing side. Further, the control device 17a is provided with a duration determination unit 23 for determining that the load acting on the movable body 12 has continued for a certain period of time.

  Based on the determination result of the duration determination unit 23, the buzzer 22 generates a buzzer sound when a set fixed time has elapsed and notifies that the set fixed time has elapsed.

  In such a configuration, in the second embodiment, as in the first embodiment, the electric cylinder 16 is driven after the step 4 passes under the boarding board 5 of the boarding gate 2 on the landing side. The movable body 12 located at the accommodation position moves toward the protruding position.

  Therefore, when the escalator user who has ridden on the escalator 1 from the landing entrance 2 on the landing side puts his / her leg across the two steps 4 that are moving horizontally, the protrusion 13 that moves to the protruding position is the bottom of the foot. Therefore, the escalator user can surely notice that his / her feet are placed across the two steps 4. Thereby, it is possible to prompt the escalator user to move the foot placed on the two steps 4 onto one of the steps 4.

  In this way, when the escalator user moves his / her foot straddling the two front and rear steps 4 onto one step 4, the step 4 starts to move obliquely and the two front and rear steps 4 Even if there is a step between them, it is possible to prevent the occurrence of an accident in which the escalator user falls due to the occurrence of the step.

  Further, when the load acting on the movable body 12 is detected by the load detection unit 21 and the duration determination unit 23 determines that the load continues for a set time, the two steps 4 are displayed. This means that an escalator user who puts his / her foot on does not move his / her foot to one step 4 side.

  In such a case, the buzzer 22 is sounded based on the determination result in the duration determination unit 23 to urge the escalator user to move the foot to one of the steps 4.

  As a result, since the escalator user has placed his / her feet on the two front and rear steps 4, the occurrence of an accident in which the escalator user falls due to a step formed between the two front and rear steps 4 is further prevented. Can do.
