Detailed Description

Embodiments of the present invention (hereinafter, also referred to as "the present embodiments") are described below with reference to the drawings. It is to be noted that the present invention is merely an example, and it is needless to say that the present invention is within the scope of the present invention, which can be easily conceived by those skilled in the art by appropriately changing the gist of the present invention. In order to make the description more clear, the drawings may schematically show the width, thickness, shape, and the like of each part as compared with the actual embodiment, but the drawings are merely exemplary and do not limit the explanation of the present invention. In the present specification and the drawings, the same elements as those described above in the drawings are denoted by the same reference numerals in some cases, and detailed description thereof will be omitted as appropriate. In the following description, the vertical direction and the horizontal direction are not strictly defined, and the vertical direction and the horizontal direction are also defined as the substantially vertical direction and the substantially horizontal direction.

Next, a platform gate device (hereinafter, also simply referred to as a gate device) 100 according to the present embodiment will be described with reference to fig. 1 to 5. Note that although the gate devices provided adjacent to the boarding/alighting passage E are denoted by the reference numerals gate device 100A and gate device 100B in fig. 1 and 2, in the following description, the gate devices 100 will be described only when no particular distinction is necessary. The same applies to the respective configurations and the like included in the gate device 100.

Fig. 1 is a view of the door device according to the present embodiment as viewed from the inside of the station, and is a perspective view showing a state in which the second column member is located at the restricting position. Fig. 2 is a view of the door device according to the present embodiment as viewed from the inside of the station, and is a perspective view showing a state in which the second column member is located at the allowable position. Further, the restricting position in the present embodiment refers to a position of the second column member 20 for restricting the entrance of the passenger into the boarding passage E, and the permitting position refers to a position of the second column member 20 for permitting the entrance of the passenger into the boarding passage E. The restricted position and the allowed position in the present embodiment may be changed according to the number and the position of the doors of the railway vehicle parked near the platform P. That is, the restricted position and the allowed position are not limited to the positions shown in fig. 1 and 2. This point will be described in detail later with reference to fig. 6 to 15.

Fig. 3 is a diagram for illustrating the internal construction of the docking station under the second column member. Fig. 4 is a perspective view illustrating a gate device according to the present embodiment. Fig. 5 is a block diagram showing a gate device structure according to the present embodiment.

The door device 100 is a door provided to secure safety of passengers by preventing the passengers from falling from the platform P onto the rail, and is provided in plurality along one side edge of the rail in the platform P. The platform P is a boarding place provided for passengers to get on and off a railway vehicle (not shown) at a station where the railway vehicle (not shown) such as an electric train or a new mainline running on a track stops.

As shown in fig. 1, 2, and 4, the gate device 100 has a first columnar member 10, a second columnar member 20, a wire 30 as a restricting member, and a folding member 40 as a holding member. As shown in fig. 5, the gate device 100 includes a control unit 110 for controlling the operation of the gate device 100.

Fig. 1 shows a state in which the door apparatus 100A and the door apparatus 100B are arranged side by side on the platform P and the passenger is restricted from entering the boarding/alighting passage E by abutment of the second pillar member 20A of the door apparatus 100A with the second pillar member 20B of the door apparatus 100B. Fig. 2 illustrates a state in which the passenger is allowed to enter the boarding/alighting passage E by separating the second pillar member 20A of the door apparatus 100A and the second pillar member 20B of the door apparatus 100B from each other shown in fig. 1.

The first column member 10 is fixed to the platform P. Further, the first columnar member 10 includes a retractor 15 (see fig. 5) for winding and storing the wire 30 therein. The Retractor 15 may have an ALR (Automatic Locking Retractor) function and may be locked every time the wire 30 is wound or unwound. Further, the first pillar member 10 may be a pillar member standing upright in the vertical direction and having a height to which a person cannot span. Although not shown, the first columnar member 10 may have an opening through which the wire 30 is inserted, and one end side thereof may be connected to the retractor 15 provided inside the first columnar member 10, and the other end side thereof may be led out to the outside of the first columnar member 10.

The second column member 20 is movably provided on the platform P between an allowable position for allowing passengers to enter the boarding passage E and a restricting position farther from the first column member 10 than the allowable position for restricting passengers from entering the boarding passage E. Here, the boarding/alighting passage E is defined as a passage for passing when a passenger located inside the door device 100 on the platform P moves toward the inside of the railway vehicle when the railway vehicle parks at the station, or moves from the inside of the railway vehicle toward the inside of the door device 100 on the platform P. As shown in fig. 2, the boarding/alighting passage E of the present embodiment is a region in which one side of the first columnar member 10 is adjacent to the opposite side with respect to the second columnar member 20 in a state in which the second columnar member 20 is located at the allowable position.

Like the first pillar member 10, the second pillar member 20 may be a pillar member standing in the vertical direction and having a height to which a person cannot span. In the present embodiment, although the outer shapes of the first columnar member 10 and the second columnar member 20 are substantially the same shape, the present invention is not limited thereto.

Also, as shown in fig. 4, the second column member 20 may have a person detection sensor 21 on a side surface thereof (a surface facing the getting-on/off passage E). The human detection sensor 21 may be, for example, an infrared sensor or a temperature sensor for detecting the presence of a human. When the person detection sensor 21 detects the presence of a person on the getting on/off lane E, the control section 110 stops the operation of the second column member 20 or moves the second column member 20 toward the allowable position. By providing the person detection sensor 21 on the second column member 20 in this way, a person can be prevented from being caught in the door apparatus 100. Further, the present embodiment shows an example in which one, two, and one in total of four human detection sensors 21 are provided above and below in the vertical direction. In this way, by providing the person detection sensors 21 at a plurality of positions in the vertical direction, it is possible to more accurately detect the presence of a person on the getting-on/off passage E. Further, the number or configuration of the human detection sensors 21 is not limited to that shown in fig. 4. Further, the detector is not limited to a detector that detects only a person, and a sensor that can detect an object such as an animal or a wheelchair other than a person may be used.

Also, as shown in fig. 4, the second column member 20 may have a lamp 23. The lamp 23 may blink in blue, for example, during the movement of the second column member 20. Thus, the passenger can visually easily grasp the state in which the second column member 20 is moving, and safety is improved. Also, when a person touches the second column member 20 or a person is on the getting on/off lane E while the second column member 20 is moving, the lamp 23 may blink in red when the person detection sensor 21 described above detects a person. In this way, the station staff or the like can visually recognize the danger by observing the second column member 20, and can prevent the occurrence of an accident.

One end of the wire 30 is provided on the first columnar member 10, and the other end is provided on the second columnar member 20 so as to extend in a parallel direction in the horizontal direction. Specifically, a restricting portion of the wire 30, which has a length corresponding to the distance between the first and second

cylindrical members

10 and 20, extends between the first and second

cylindrical members

10 and 20 to restrict the entrance of passengers into the getting-on/off passage E between the first and second

cylindrical members

10 and 20, and a non-restricting portion connected to the restricting portion is received in the first cylindrical member 10. Further, the restricted portion of the metal wire 30 refers to a portion of the metal wire 30 shown in fig. 1 and the like, and the non-restricted portion of the metal wire 30 refers to a portion that is housed in the first columnar member 10 and is not shown in the drawings for showing the appearance of the gate device 100.

Further, although the present embodiment shows an example in which the gate device 100 has four metal wires 30 arranged side by side at equal intervals in the vertical direction, the number or arrangement of the metal wires 30 is not limited thereto as long as it is possible to restrict the passenger from crossing or passing through.

Further, although the present embodiment shows the wire 30 as a restricting member for restricting the passenger from entering the boarding/alighting passage E, it is not limited to the wire, and may be a rope or the like. The regulating member may be a belt-like member having a predetermined width in the vertical direction. When a band-shaped member having a width substantially equal to the height of the first columnar member 10 and the second columnar member 20 is used as the restricting member, the folding member 40 described later may be omitted. When a belt-like member having a predetermined width in the vertical direction is used as the restricting member, an opening corresponding to the width may be provided in the first columnar member 10, the restricting member may be wound around the retractor 15, and the restricting member may be housed in the first columnar member 10.

The folding member 40 is configured such that one end 41 is provided on the first columnar member 10 and the other end 42 is provided on the second columnar member 20, and is folded between the first columnar member 10 and the second columnar member 20 as the second columnar member 20 moves from the restriction position toward the allowable position. Fig. 2 shows a state in which the folding member 40 is folded, and fig. 1 shows a state in which the folding member 40 is unfolded.

As shown in fig. 4 and the like, the folding member 40 is a corrugated member including a plurality of valley portions 45 protruding in the getting-off direction of the getting-on/off passage E and a plurality of peak portions 47 adjacent to the valley portions 45 and protruding in the getting-on direction. The folding member 40 has a through hole 43 formed between the valley portion 45 and the peak portion 47. The metal wire 30 is inserted through the through hole 43, and is held at a vertical position by the inner peripheral surface of the through hole 43. This enables the distance between the wires 30 to be maintained even when the wires 30 are stretched in the vertical direction. Further, although the folding member 40 is shown as the holding member in the present embodiment, it is not limited thereto as long as the holding member can suppress the distance between the wires 30 to a degree that the passenger can drill when the wires 30 are stretched in the vertical direction. The holding member may be, for example, a wire-shaped member in which a plurality of wires 30 arranged in parallel in the vertical direction extend in the vertical direction so as to be connected to each other. By providing the holding member such as the folding member 40 in this way, the safety of the passenger can be further ensured.

The folding member 40 is preferably lightweight and may be made of, for example, vinyl. The folding member 40 may be a mesh member that is lightweight and can reduce the influence of wind pressure due to passage of railway vehicles or the like. The folding member 40 as the holding member is not necessarily configured, and the door device 100 may be configured to have at least a restriction member such as the wire 30 and to be able to restrict the passenger from entering the boarding/alighting passage E.

The control unit 110 can acquire information on the railway vehicle that stops next to the platform P, and then control the restricting position of the second column member 20 based on the information. Further, the information on the railway vehicle may include the number of vehicles, the number of doors, the door position, and the like of the railway vehicle which is next parked beside the platform P. The information on the railway vehicle may be transmitted to the control unit 110 from a central control room or the like that performs operation management of the railway vehicle in the station or at a place remote from the station.

The operation of the second columnar member 20 in the present embodiment will be described mainly with reference to fig. 3 and 4. Further, fig. 3 shows a cross-sectional view of the internal configuration of the platform P, and shows a side view of the second column member 20 as viewed from the side of the boarding/alighting passage E. Fig. 4 shows the guide shaft 50a, the drive shaft 50b, the support member 60a for supporting the lower surface of the second columnar member 20, and the support member 60b, which are provided in the ground of the platform P, by omitting the illustration of the platform P and the ground structure 70 described later. In fig. 3, illustration of the guide shaft 50a and the drive shaft 50b is omitted.

The drive shaft 50b is a spiral member that is rotatably provided inside the ground of the platform P along the boarding/alighting path E and has a spiral portion formed on the peripheral surface thereof. As shown in fig. 5, the present embodiment uses an actuator 90 for rotationally driving the drive shaft 50 b. The actuator 90 may be built in a fixing member 80 (refer to fig. 4) that is fixed to the platform P by being fitted in a groove formed on the platform P to fix the first column member 10 to the platform P. Further, the actuator 90 may include a servo motor, for example.

Further, the guide shaft 50a is provided inside the ground of the platform P in parallel with the drive shaft 50b and rotatably along the boarding/alighting path E.

Further, the gate device 100 has a support member 60a and a support member 60b fixed to the lower surface of the second column member 20 and supporting the second column member 20. The support member 60a has an insertion hole 61a for insertion of the guide shaft 50 a. The cross-sectional shape of the insertion hole 61a is circular, and the inner circumferential surface of the insertion hole 61a may be configured to be non-contact with the guide shaft 50a or to slide on the guide shaft 50 a.

The support member 60b has an insertion hole 61b for insertion of the drive shaft 50b therethrough and is formed with a spiral groove (engaging portion) for engagement with a spiral portion formed on the drive shaft 50 b. The drive shaft 50b is rotationally driven by the actuator 90, and the support member 60b moves along the drive shaft 50 b. The second cylindrical member 20 moves between the restricting position and the allowing position by the support member 60b moving along the drive shaft 50 b.

Further, although fig. 4 shows the guide shaft 50a having the spiral portion formed on the circumferential surface, it is not limited thereto, and the spiral portion may not be formed at a portion of the guide shaft 50a within the moving range of the second cylindrical member 20. That is, the cross-sectional shape of the portion of the guide shaft 50a within the range in which the second cylindrical member 20 moves may be circular without irregularities or the like.

In the guide shaft 50A, a portion in the moving range of the second cylindrical member 20 (corresponding to the second cylindrical member 20A of fig. 1 and the like) that abuts the second cylindrical member 20 (corresponding to the second cylindrical member 20B of fig. 1 and the like) shown in fig. 4 to restrict the entrance of passengers into the boarding/alighting passage E may be formed with a spiral portion on the peripheral surface of the guide shaft 50A. Further, the guide shaft 50A may function as a drive shaft of the second cylindrical member 20 (corresponding to the second cylindrical member 20A of fig. 1 and the like).

The drive shaft 50b may be a shaft member whose section is circular in shape and whose portion that is not within the moving range of the second cylindrical member 20 (corresponding to the second cylindrical member 20A of fig. 1 or the like) for restricting the entrance of passengers into the boarding passage E forms a spiral portion. The drive shaft 50b can function as a drive shaft of the second cylindrical member 20 (corresponding to the second cylindrical member 20A of fig. 1 and the like).

Further, the drive shaft 50b may be configured to be freely rotatable when the actuator 90 loses power. By adopting such a configuration, when the actuator 90 loses power, the second column member 20 can be moved by manually pushing it, so that safety in emergency or the like can be ensured.

In order to stably and smoothly move the support member 60a, the support member 60a may include wheels 62a that rotate on a ground structure 70, which will be described later. Likewise, the support member 60b may also have wheels 62 b. Further, as shown in fig. 4, three

wheels

62a, 62b are provided along the moving direction of the second column member 20 in the present embodiment, respectively. However, the number of the

wheels

62a and 62b is not limited to this, and not only the wheels but also a rotating body such as a wheel that rotates on the ground structure 70 may be used.

As shown in fig. 3, a groove P1 having a rectangular cross-sectional shape is formed in the platform P along the boarding/alighting passage E, and the floor structure 70 is installed in the groove P1. As shown in fig. 3, the ground structure 70 includes a first ground structure 71 and a second ground structure 72, the first ground structure 71 being provided so as to contact the side surface P11 and the bottom surface P12 formed by the groove P1, and the second ground structure 72 being provided on the first ground structure 71, being in contact with the wheel 24 provided on the lower surface of the second columnar member 20, and serving as a tunnel member for the tunnel of the second columnar member 20.

The cross-sectional shape of the first floor structure 71 may be a shape having a space along the shape of the

support members

60a and 60 b. As shown in fig. 3, in the present embodiment, the first ground structure 71 has a shape having a slope on which the wheel 62a of the support member 60a and the wheel 62b of the support member 60b move.

In addition, in order to improve maintenance performance, the first floor structure 71 may be detachably attached to the platform P by bolts or the like. The second floor structure 72 may be detachably attached to the first floor structure 71 by bolts or the like at the station P so as to cover the guide shaft 50a and the drive shaft 50 b.

Next, an example of the arrangement and operation of the door apparatus 100 will be described with reference to fig. 6 to 15. Fig. 6 to 15 are plan views of an example of the door device as viewed from the upper side in the vertical direction in a state where the railway vehicle is parked near the platform. In fig. 6 to 15, the side where the gate device 100A is provided is the front side, and the side where the gate device 100B is provided with respect to the gate device 100A is the rear side. In fig. 6 to 15, a door provided in the railway vehicle for passengers to get on and off is shown by a broken line.

Further, the gate device 100D has a first columnar member 10D, a second columnar member 20D, a wire 30D, and a folding member 40D.

Fig. 6 shows a state in which the second pillar member 20A and the second pillar member 20B1 are located at the restricting positions to restrict the passenger from entering the boarding/alighting path E1 (see fig. 9 and the like). Fig. 6 shows a state in which the second pillar member 20B2 and the second pillar member 20C1 are located at the restricting positions and the passenger is restricted from entering the boarding/alighting passage E3 (see fig. 9 and the like). Fig. 6 shows a state in which the second pillar member 20C2 and the second pillar member 20D are located at the restricting position to restrict the passenger from entering the boarding/alighting path E2 (see fig. 9 and the like).

Fig. 7 shows a state in which a railway vehicle 200 having one door 210 provided in front of the vehicle according to the first embodiment is parked near a platform P. Thus, when the railway vehicle 200 having the single door 210 at the front thereof is parked at the platform side, only the passengers can enter the boarding/alighting passage E1. That is, at least the second column member 20A or the second column member 20B1 can be moved from the restricted position to the permitted position. The example of fig. 7 shows a state in which a passenger riding in the railway vehicle 200 can get off the door 210 and get on the railway vehicle 200 from the door 210 by moving only the second column member 20A to the allowable position.

Fig. 8 shows a state in which a railway vehicle 300 having one door 310 at the front and one door 320 at the rear of the vehicle of the first embodiment is parked near a platform P. When the railway vehicle 300 is parked at the platform P, passengers can enter the boarding/alighting passage E1 and the boarding/alighting passage E2. That is, at least the second column member 20A or the second column member 20B1 can be moved from the restricted position to the allowable position, and at least the second column member 20C2 or the second column member 20D can be moved from the restricted position to the allowable position. The example of fig. 8 shows a state in which passengers who ride on the railway vehicle 300 can get off the

doors

310 and 320 and passengers on the platform P can get on the railway vehicle 300 from the

doors

310 and 320 by moving the second column member 20A, the second column member 20B1, the second column member 20C2, and the second column member 20D to the allowable positions, respectively.

Fig. 9 shows a state in which a railway vehicle 400 having one door 410 provided at the front of the vehicle, one door 420 provided at the rear, and one door 430 provided therebetween is parked near a platform P in the first embodiment. When the railway vehicle 400 is parked at the platform P, passengers can enter the boarding/alighting passage E1, the boarding/alighting passage E2, and the boarding/alighting passage E3. In addition to the state of the example shown in fig. 8, fig. 9 shows a state in which the second column member 20B2 and the second column member 20C1 are moved to the allowable positions. This enables passengers who are riding on the railway vehicle 400 to get off the railway vehicle from the

doors

410, 420, and 430, and passengers at the platform P to get on the railway vehicle 400 from the

doors

410, 420, and 430.

Fig. 10 shows a state in which a railway vehicle 500 having one door 510 provided at the front of the vehicle, one door 520 provided at the rear thereof, and two

doors

530 and 540 provided therebetween is parked near a platform P in the first embodiment. When the railway vehicle 500 is parked at the platform P, passengers can enter the boarding/alighting passage E1, the boarding/alighting passage E2, and the boarding/alighting passage E3. Further, when the railway vehicle 500 is parked at the platform P, the boarding/alighting passage E3 becomes a passage allowing boarding/alighting from the two

doors

530 and 540, and therefore, the second columnar member 20B2 can be moved toward the first columnar member 10B side and the second columnar member 20C1 can be moved toward the first columnar member 10C side, as compared with the state of the example shown in fig. 9. Further, in the embodiment shown in fig. 10, since the moving amounts of the second column member 20B2 and the second column member 20C1 when moving from the restricted position toward the permitted position are large, the moving amounts of the other second column members 20 are also increased accordingly, and the width of the boarding/alighting passage E is increased. In contrast, in the example shown in fig. 9, since the moving amounts of the second column member 20B2 and the second column member 20C1 when moving from the restricted position toward the permitted position are small, the moving amounts of the other second column members 20 are also made small by that amount.

As described above, in the first embodiment, the passenger can get on or off the railway vehicle by using the minimum movement amount and the minimum power according to the number and the position of the doors of the railway vehicle. As shown in fig. 10, by forming one entrance lane for a plurality of doors of the railway vehicle, that is, by widening the width of the entrance lane, passengers can get on and off the railway vehicle without increasing the number of door devices 100 provided on the platform P. As a result, the cost and time required for installing the gate device 100 at the station P can be reduced.

Fig. 11 and 12 show a second embodiment in which the

gate devices

100A, 100B, and 100C are provided on the platform P. The second embodiment shows an example of a railway vehicle having four doors which enables passengers to get on and off by fewer door devices 100 than the first embodiment.

In the second embodiment, the gate device 100A has a first pillar member 10A, a second pillar member 20A, a wire 30A, and a folding member 40A. Further, the gate device 100B has a first pillar member 10B, a second pillar member 20B1, a wire 30B1, a folding member 40B1, a second pillar member 20B2, a wire 30B2, and a folding member 40B 2. Further, the gate device 100C has a first pillar member 10C, a second pillar member 20C, a wire 30C, and a folding member 40C.

Fig. 11 shows a state in which the second pillar member 20A and the second pillar member 20B1 are located at the restricting positions to restrict the passenger from entering the boarding/alighting path E1 (see fig. 12 and the like). Fig. 11 shows a state in which the second pillar member 20B2 and the second pillar member 20C are located at the restricting position to restrict the passenger from entering the boarding/alighting path E3 (see fig. 12 and the like).

Fig. 12 shows a state in which a railway vehicle 600 having one door 610 at the front, one door 620 at the rear, and two

doors

630 and 640 provided therebetween is parked near a platform P in the second embodiment. When the railway vehicle 600 is parked at the platform P, passengers can enter the boarding/alighting passage E1 and the boarding/alighting passage E2. Fig. 12 shows a state in which the second column member 20A, the second column member 20B1, the second column member 20B2, and the second column member 20C are moved to the allowable positions. This enables passengers who ride the railway vehicle 600 to get off the

doors

610, 620, 630, and 640, and passengers at the platform P to get on the railway vehicle 600 from the

doors

610, 620, 630, and 640.

Fig. 13 to 15 show a third embodiment in which the

gate devices

100A and 100B are provided on the platform P. In the third embodiment, an example in which passengers can get on and off the railway vehicle by fewer gate devices 100 than the number of the first and second embodiments is shown.

In the third embodiment, the gate device 100A has a first pillar member 10A, a second pillar member 20A, a wire 30A, and a folding member 40A. Further, the gate device 100B has a first columnar member 10B, a second columnar member 20B, a wire 30B, and a folding member 40B.

Fig. 13 shows a state in which a railway vehicle 700 having a single door 730 provided near the center in the vehicle front-rear direction of the third embodiment is parked near a platform P. When the railway vehicle 700 is parked beside the platform P, the passengers can enter the boarding/alighting passage E3. Fig. 13 shows a state where the second column member 20A and the second column member 20B are moved to the allowable positions. This allows the passenger on the railway vehicle 700 to get off the door 730 and allows the passenger on the platform P to get on the railway vehicle 700 through the door 730.

Fig. 14 shows a state where a railway vehicle 800 having one door 820 provided at the rear of the vehicle of the third embodiment is parked near a platform P. When the railway vehicle 800 is parked beside the platform P, passengers can enter the boarding/alighting passage E2. Fig. 14 shows a state in which the second column member 20A and the second column member 20B are moved to the allowable positions. This enables passengers who are seated in the railway vehicle 800 to get off the door 820, and passengers at the platform P to get on the railway vehicle 800 from the door 820.

Fig. 15 shows a state in which a railway vehicle 900 having one door 910 provided at the front and one door 920 provided at the rear and two

doors

930 and 940 provided therebetween is parked near a platform P in the third embodiment. When the railway vehicle 900 is parked beside the platform P, the passengers can enter the boarding/alighting passage E1. Fig. 15 shows a state where the second column member 20A and the second column member 20B are moved to the allowable positions. This enables passengers who are riding in the railway vehicle 900 to get off the railway vehicle 900 through the

doors

910, 920, 930, and 940, and passengers at the platform P to get on the railway vehicle 900 through the

doors

910, 920, 930, and 940.

The third embodiment shown in fig. 13 to 15 shows an example in which passengers can get on and off the railway vehicle by using the minimum movement amount and power according to the number and position of doors of the railway vehicle. The control unit 110 according to the third embodiment may acquire information on the railway vehicle in advance before the arrival of the railway vehicle, and may move the second column member 20 to a position facing the door of the parked railway vehicle in advance. That is, if the next-to-stop railway vehicle is the railway vehicle 700 shown in fig. 13, the second column member 20B of the second column member 20A may be moved to the vicinity of the center of the vehicle in advance, and if the next-to-stop railway vehicle is the railway vehicle 800 shown in fig. 14, the second column member 20A and the second column member 20B may be moved to the rear of the vehicle in advance. This enables the railway vehicle to be parked beside the platform P and then the passengers to be allowed to enter the boarding/alighting passage E in a short time. Further, the wire 30 may be a length that enables the second column member 20 to move according to the number and position of doors of the railway vehicle. That is, the wire 30 may have a length corresponding to the restriction position of the second column member 20 controlled by the control unit 110. For example, in a state where the second columnar member 20A is located at a position closest to the first columnar member 10A, the maximum length of the wire 30B may be a length that enables the second columnar member 20B to abut against the second columnar member 20A. The same applies to the folding member 40A and the folding member 40B.

Although the example in which the first columnar member 10 is fixed to the platform P is described in the present embodiment, the first columnar member 10 may be provided movably on the platform P as in the case of the second columnar member 20. Further, although the example in which the wire 30 is wound and housed in the first columnar member 10 is described in the present embodiment, the wire 30 may be wound and housed in the second columnar member 20, or may be wound and housed in both the first columnar member 10 and the second columnar member 20.

In the present embodiment, the double door is described, but the present invention is not limited to this, and the door may be a single door. That is, the entrance of the passenger into the boarding/alighting passage E may be restricted by moving the second column member 20 to the restriction position adjacent to the column member fixedly provided on the platform P.

Further, although an example in which the second column member 20 is moved using the drive shaft 50b or the like is described in the present embodiment, it is not limited thereto. For example, a driving mechanism may be provided on the main body of the second column member 20 to move the second column member 20 on a track formed on the platform P.

In the present embodiment, the first columnar member 10A, the first columnar member 10B, the second columnar member 20A, and the second columnar member 20B correspond to the first columnar member, the third columnar member, the fourth columnar member, and the fifth columnar member, respectively.

Next, a modification of the present embodiment will be described with reference to fig. 16. Fig. 16 is a diagram showing an internal structure of the platform under the second column member 20 in the modification. Note that the same reference numerals are used for the same components as those shown in fig. 3, and detailed description thereof is omitted.

Although the above-described embodiment has described the example in which the drive shaft 50b shown in fig. 3 and 4 is driven by the drive source to move the second column member 20 up and down, the driving method of the second column member 20 is not limited to this. In the modification, an example in which the second column member 20 is moved on the platform P by being driven by the motor 190 as a driving source built in the second column member 20 will be described.

The second column member 20 in the modification has a motor 190 and a pinion 191 that rotates with the rotation of the motor 190. The motor 190 is housed in a case for constituting a housing of the second column member 20. The pinion 191 is exposed and disposed below a housing for constituting a housing of the second column member 20. A gear train for transmitting the driving force of the motor 190 to the pinion 191 may be provided between the motor 190 and the pinion 191.

Also, the second column member 20 has a support member 160a and a support member 160b fixed below the second column member 20 and used to support the second column member 20. The support member 160a includes wheels 162a that rotate on a ground structure 170, which will be described later, in order to stably and smoothly move the support member 160 a. The support member 160b also has wheels 162 b. The number and number of wheels 162a and 162b are not limited to those shown in fig. 16. Further, the shape of the support members 160a, 160b is not limited to that shown in fig. 16.

Further, a groove P1 having a rectangular cross-sectional shape is formed in the platform P of the modified example along the boarding/alighting passage E, and the floor structure 170 is formed in the groove P1. The floor structure 170 is provided along the boarding/alighting passage E and has a rack 150 for meshing with a pinion gear 190 of the second column member 20. The rotational driving of the motor 190 rotates the pinion 190 engaged with the rack 150, thereby causing the pinion 190 to perform a relative movement with respect to the rack 150. This causes the second column member 20 to perform relative movement with respect to the rack 150 provided along the getting-on/off passage E.

The above-described configuration enables the second column member 20 in the modification to move on the platform P.

Further, the configuration of the second columnar member 20 in the modification may be applied to the first columnar member 10. That is, the first cylindrical member 10 may also have a motor and a pinion gear that rotates with the rotation of the motor and meshes with the rack 150. With this configuration, it is possible to move not only the second columnar member 20 but also the first columnar member 10 on the platform P. Therefore, the degree of freedom in forming the opening position of the boarding passage E can be improved.
