  As shown in FIG. 3, the roller actuator 12 is attached to the upper end portion of the shaft portion 15 on the upper side of the guide roller 11. The roller actuator 12 applies a rotational driving force to the shaft portion 15 of the guide roller 11 in accordance with a drive command from the control panel 6. In addition, the roller actuator 12 can rotate the guide roller 11 in any direction.

Next, the arrangement of the guide rollers 11 and the configuration in the vicinity of the guide rollers 11 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a plan view of an essential part of an escalator in which the passenger conveyor safety device according to Embodiment 1 of the present invention is used. FIG. 5 is a side view of an essential part of an escalator in which the passenger conveyor safety device according to Embodiment 1 of the present invention is used.

  As shown in FIGS. 4 and 5, a safety line 16 is provided on the riser side edge of the adjacent step 7 on the upper surface of the step 7. Safety lines 16 are also provided on both side edges of the upper surface of step 7. These safety lines 16 are generally formed of a yellow material. Thereby, a dangerous position is displayed with respect to the passenger who got on the upper surface of Step 7.

  As shown in FIGS. 4 and 5, a plurality of notches 17 are provided on the side surface of the skirt guard 8 on the step 7 side corresponding to each of the guide rollers 11. These notches 17 have the longitudinal direction of the escalator 1 in the traveling direction. The height of the cutout portion 17 is slightly higher than the thickness of the main body portion 14 of the guide roller 11.

  And the guide roller 11 is arrange | positioned inside the skirt guard 8 in the state which exposed the step 7 side of the main-body part 14 from the notch part 17 of the skirt guard 8 to the step 7 side. As a result, the outer peripheral surface on the step 7 side of the guide roller 11 does not come into contact with the step 7 but is arranged close to the edge on the skirt guard 8 side of the upper surface of the step 7.

  Inside the skirt guard 8, each of the upper and lower shaft portions 15 of the guide roller 11 is supported by the end portion of the support 18 on the skirt guard 8 side. The shaft portions 15 of these guide rollers 11 are movable along the support 18 in the horizontal direction and in the direction perpendicular to the traveling direction of the escalator 1.

  Inside these supports 18, a support plate 19 is accommodated on the side opposite to the skirt guard 8 side of the shaft portion 15 of the guide roller 11 so as to be movable in the horizontal direction and in the direction perpendicular to the traveling direction of the escalator 1. Further, inside the support 18, the adjustment spring 20 is accommodated in the horizontal direction and in the direction perpendicular to the traveling direction of the escalator 1, in a manner that can be expanded and contracted, on the opposite side of the support plate 19 from the shaft 15 side of the guide roller 11.

  Then, on the outside of the end of the support 18 opposite to the skirt guard 8 side, the pushing plate 21 is fixed to the end of the adjustment spring 20 opposite to the support plate 19 side. In the first embodiment, one pushing plate 21 is provided for the three guide rollers 11. That is, the end of the six adjustment springs 20 provided on the top and bottom of the three guide rollers 11 on the opposite side to the support plate 19 side is fixed to one pushing plate 21.

  And the skirt guard approach detection switch 22 is arrange | positioned adjacent to the center of the side opposite to the adjustment spring 20 side of the pushing board 21. FIG.

  Here, consider a case where an object such as a sandal 23 or boots worn by a passenger approaches the skirt guard 8. In this case, objects such as sandals 23 and boots are in contact with the outer peripheral surface of the guide roller 11 on the step 7 side. Further, when an object such as a sandal 23 or boots moves to the skirt guard 8 side, the guide roller 11 is pushed into the skirt guard 8. That is, the shaft portion 15 of the guide roller 11 moves to the outside of the escalator 1.

  Following this movement, the support plate 19 moves to the outside of the escalator 1. And the adjustment spring 20 is pushed in the outer side of the escalator 1 by this movement. Then, the adjustment spring 20 pushes the pushing plate 21 to the outside of the escalator 1 using the restoring force.

  By this pushing, the pushing plate 21 moves to the outside of the escalator 1. With this movement, the skirt guard approach detection switch 22 is pressed. By such pressing, the control panel 6 detects that an object such as a sandal 23 or boots is approaching the skirt guard 8.

  That is, the skirt guard approach detection switch 22 functions as a skirt guard approach detection device that detects an object approaching the skirt guard 8 by detecting the pressure applied to the guide roller 11.

Next, the roller actuator driving switch 13 will be described with reference to FIG.
FIG. 6 is a front view for explaining the roller actuator driving switch used in the passenger conveyor safety device according to Embodiment 1 of the present invention.
As shown in FIG. 6, the roller actuator driving switch 13 is a circular wall-embedded switch. On the upper center side of the surface of the roller actuator driving switch 13, “drive” is indicated. When the passenger himself depresses the roller actuator driving switch 13, the depressing information flows to the control panel 6.

  Here, before explaining the operation of the safety device of the present embodiment, the sandals 23 and boots worn by the passengers on the escalator 1 not using the safety device of the present embodiment will be described with reference to FIGS. The situation when an object is pinched will be described.

  FIG. 7 is a main part front view for illustrating a situation immediately before sandals or the like are sandwiched by an escalator that does not use the passenger conveyor safety device according to Embodiment 1 of the present invention. FIG. 8 is a front view of an essential part for explaining a situation immediately after a sandal or the like is sandwiched by an escalator that does not use the passenger conveyor safety device according to Embodiment 1 of the present invention.

  FIG. 9 is a plan view of a main part for explaining the sandwiching direction of sandals or the like when the escalator that does not use the passenger conveyor safety device according to Embodiment 1 of the present invention is in an ascending operation. FIG. 10 is a plan view of a main part for explaining the sandwiching direction of sandals or the like when the escalator that does not use the passenger conveyor safety device according to Embodiment 1 of the present invention is in the descending operation.

  As shown in FIG. 7, when an object such as a sandal 23 or boots worn by a passenger is pressed against the skirt guard 8 from step 7, a frictional force is generated between the skirt guard 8 and an object such as the sandal 23 or boots. . Due to this frictional force, the contact portion of the object such as the sandal 23 or the boots with the skirt guard 8 tends to stay on the spot.

  However, the foot of the passenger on step 7 moves in the direction of travel of the escalator 1. As a result, the vicinity of the skirt guard 8 of an object such as a sandal 23 or boots is pulled and stretched. Thereby, the thickness in the vicinity of the skirt guard 8 of objects such as the sandals 23 and the boots becomes thin.

  As shown in FIG. 8, the vicinity of the skirt guard 8 of an object such as a thin sandal 23 or boots is caught in the gap between the step 7 and the skirt guard 8. As a result, the vicinity of the skirt guard 8 of an object such as a thin sandal 23 or boots is sandwiched between the gaps between the step 7 and the skirt guard 8.

  As described above, the contact portion of the object such as the sandal 23 or the boots with the skirt guard 8 tries to stay on the spot. However, the foot of the passenger on step 7 moves in the direction of travel of the escalator 1. Accordingly, as shown in FIGS. 9 and 10, when viewed from the passenger on step 7, the sandwiched direction of the objects such as the sandals 23 and the boots is generated in the direction opposite to the traveling direction of the escalator 1.

  Here, when the escalator 1 is in an uphill driving, even if the contact portion of the object such as the sandals 23 or the boots with the skirt guard 8 stays on the spot, the step 7 on which the passenger is placed rises. For this reason, the stretched portion of the object such as the sandals 23 or the boots near the skirt guard 8 increases the amount of biting into the gap between the step 7 and the skirt guard 8 as the step 7 rises.

Next, with reference to FIG. 11 and FIG. 12, a situation in which the escalator 1 using the safety device of the present embodiment prevents objects such as sandals 23 and boots from being pinched will be described.
FIG. 11 is a main part plan view for explaining a situation in which sandals or the like are prevented from being caught when the escalator using the passenger conveyor safety device according to Embodiment 1 of the present invention is in an ascending operation. FIG. 12 is a plan view of relevant parts for explaining a situation in which sandals and the like are prevented from being caught when the escalator that does not use the passenger conveyor safety device according to Embodiment 1 of the present invention is in the descending operation.

  In the escalator 1 using the safety device according to the present embodiment, when a passenger's foot approaches the skirt guard 8 on the step 7, objects such as sandals 23 and boots worn by the passenger are located on the step 7 side of the guide roller 11. Contact the outer peripheral surface. A frictional force is generated between the guide roller 11 and an object such as a sandal 23 or boots.

  In this state, when the passenger's foot on the step 7 moves in the traveling direction of the escalator 1, the guide roller 11 moves the outer peripheral surface on the step 7 side in the traveling direction of the escalator 1 using the friction force as a driving force. Rotate to. Such rotation reduces the frictional force between the guide roller 11 and an object such as a sandal 23 or boots.

  Therefore, normally, the vicinity of the skirt guard 8 of an object such as the sandal 23 or the boots is not stretched by pulling. For this reason, normally, the vicinity of the skirt guard 8 of an object such as the sandal 23 or the boots is not sandwiched between the step 7 and the skirt guard 8. However, it is also conceivable that the vicinity of the skirt guard 8 of an object such as a sandal 23 or boots is sandwiched between the step 7 and the skirt guard 8 due to an unexpected situation.

  Therefore, in the safety device of the present embodiment, the roller actuator 12 positively rotates the guide roller 11 so that the rotational movement direction of the outer peripheral surface on the step 7 side of the guide roller 11 becomes the movement direction of the escalator 1. The rotational speed of the guide roller 11 at this time can be set as appropriate.

  Specifically, as shown in FIG. 11, when the passenger conveyor is in ascending operation, the roller actuator 12 attached to the right guide roller 11 as viewed from above rotates the corresponding guide roller 11 in the clockwise direction. . On the other hand, the roller actuator 12 attached to the left guide roller 11 as viewed from above rotates the corresponding guide roller 11 in the counterclockwise direction.

  On the other hand, as shown in FIG. 12, when the passenger conveyor is in the descending operation, the roller actuator 12 attached to the right guide roller 11 as viewed from above rotates the corresponding guide roller 11 in the direction opposite to the clockwise direction. . In contrast, the roller actuator 12 attached to the left guide roller 11 as viewed from above rotates the corresponding guide roller 11 in the clockwise direction.

  For this reason, in an unexpected situation, objects such as sandals 23 and boots sandwiched between the gap between the step 7 and the skirt guard 8 are pushed out from the gap between the step 7 and the skirt guard 8. That is, the sandwiched sandals 23 and boots are actively removed by the rotational drive of the guide roller 11 by the roller actuator 12.

Next, the operation of the safety device will be described with reference to FIG. 13 focusing on the software processing in the control panel 6.
FIG. 13 is a flowchart for explaining the operation of the passenger conveyor safety device according to Embodiment 1 of the present invention.
First, in step S1, the control panel 6 determines whether or not the skirt guard approach detection switch 22 detects the approach of an object such as a sandal 23 or a boot to the skirt guard 8. When the approach of the object such as the sandals 23 or the boots to the skirt guard 8 is detected, the process proceeds to step S2.

  In step S2, the control panel 6 determines that the passenger is in a dangerous state, causes the announcement device 10 to issue a warning message for approaching the skirt guard 8, and proceeds to step S3. In step S3, the control panel 6 determines whether or not the operating direction of the escalator 1 is a downward direction. When the driving direction of the escalator 1 is the downward direction, the process proceeds to step S4.

  In step S4, the control panel 6 sets the rotation direction of the guide roller 11 by the right roller actuator 12 as viewed from above to be counterclockwise, that is, counterclockwise. Further, the control panel 6 sets the rotation direction of the guide roller 11 by the left roller actuator 12 when viewed from above to be clockwise, that is, clockwise, and proceeds to step S5. In step S5, the control panel 6 causes the roller actuators 12 on both sides to continuously drive the guide roller 11 in the set rotation direction for a predetermined time, and the operation ends.

  On the other hand, when the driving direction of the escalator 1 is the upward direction in step S3, the process proceeds to step S6. In step S6, the control panel 6 sets the rotation direction of the right roller actuator 12 as viewed from above in the clockwise direction, that is, in the clockwise direction. Further, the control panel 6 sets the rotation direction of the left roller actuator 12 as viewed from above to be counterclockwise, that is, the counterclockwise direction, and proceeds to step S5. In step S5, the control panel 6 causes the roller actuators 12 on both sides to continuously drive the guide roller 11 in the set rotation direction for a predetermined time, and the operation ends.

  If the approach of the object such as the sandals 23 or the boots to the skirt guard 8 is not detected in step S1, the process proceeds to step S7. In step S7, the control panel 6 determines whether or not the roller actuator driving switch 13 is pressed. If the roller actuator drive switch 13 is not pressed, the operation is terminated.

  On the other hand, for example, when the roller actuator driving switch 13 is pressed by the operation of a passenger who notices that an object such as the sandal 23 or the boots is caught, the operations in steps S3 to S6 are performed. That is, the control panel 6 rotates the guide roller 11 by determining the operation direction of the escalator 1, setting and driving the rotation direction of the roller actuator 12, and the operation ends.

  In the above operation, only the guide roller 11 corresponding to the skirt guard approach detection switch 22 that detects an object such as the sandals 23 or boots may be rotationally driven. Alternatively, only the guide roller 11 in the vicinity of the pressed roller actuator driving switch 13 may be rotationally driven. In these cases, the guide roller 11 is rotationally driven only at a position where there is a high possibility that an object such as the sandals 23 or boots is pinched, and power consumption can be reduced.

  According to the first embodiment described above, the guide roller 11 is close to the edge of the skirt guard 8 on the upper surface of the step 7 so that the rotational movement direction of the outer peripheral surface on the step 7 side is the traveling direction of the escalator 1. Arranged. For this reason, even if the passenger approaches the skirt guard 8 and enters the step 7, the object such as the sandal 23 or the boots worn by the passenger contacts the guide roller 11. And the outer peripheral surface of the guide roller 11 which contacted objects, such as the sandal 23 and a boot, rotates in the advancing direction of the escalator 1. FIG. Thereby, it can prevent that objects, such as the sandal 23 and a boots, are pinched | interposed into the clearance gap between the step 7 and the skirt guard 8. FIG.

  Further, the roller actuator 12 drives the guide roller 11 so that the outer peripheral surface on the step 7 side of the guide roller 11 rotates in the traveling direction of the escalator 1. For this reason, it is possible to prevent the sandals 23, boots and the like from being caught in the gap between the skirt guard 8 and the step 7 more positively.

  Further, when the skirt guard approach detection switch 22 detects an object such as a sandal 23 or boots, the announcement device 10 alerts the approach to the skirt guard 8 by voice. For this reason, a passenger approaching the skirt guard 8 can be alerted. The skirt guard approach detection switch 22 detects an object approaching the skirt guard 8 by detecting the pressure applied to the guide roller 11. For this reason, it is possible to detect objects such as sandals 23 and boots that are close to the skirt guard 8 with a simple configuration.

  The roller actuator 12 drives the guide roller 11 continuously for a predetermined time after the skirt guard 8 approach detection device detects an object. For this reason, the guide roller 11 can be rotationally driven only when necessary. Thereby, the power consumption by the drive of the guide roller 11 can be reduced.

  Further, a roller actuator driving switch 13 for driving the roller actuator 12 is provided. For this reason, the action which a passenger removes the sandal 23, a boots, etc. which were pinched | interposed into the clearance gap between the step 7 and the skirt guard 8 can be assisted.

  A plurality of guide rollers 11 are arranged side by side in the traveling direction of the escalator 1. Specifically, the guide roller 11 is arranged from the landing point of the escalator 1 to the landing point. For this reason, the position which prevents that objects, such as the sandal 23 and a boots, are pinched | interposed into the clearance gap between the step 7 and the skirt guard 8 can be increased.

  Moreover, the guide roller 11 is provided in the escalator 1 which raises. For this reason, when the escalator 1 where the sandals 23 and the boots are easy to bite into the gap between the skirt guard 8 and the step 7 is prevented, an object such as the sandals 23 and the boots is not caught in the gap between the step 7 and the skirt guard 8. can do.

  Further, the roller actuator 12 is provided for each guide roller 11. For this reason, the guide roller 11 that cannot be rotationally driven when the roller actuator 12 fails can be minimized.
