When the roller 42c is pushed by the blade 203 moving in the closing direction Dc, the first slider 21A and the first floor door 101A move in the closing direction Dc. That is, the rollers 42 o and 42 c function as a first opening and closing mechanism 10 that opens and closes the first floor door 101 A in accordance with the opening and closing of the car door 201. The first opening and closing mechanism 10 may also be referred to as a first interlocking mechanism that interlocks the car door 201 and the first floor door 101A.

(Second opening and closing mechanism)
FIGS. 3 to 5 are schematic plan views of the floor door opening and closing device 100A, showing the operation of the second opening and closing mechanism 20A. The second opening and closing mechanism 20A for opening and closing the second floor door 102A according to the opening and closing of the first floor door 101A is a moving pulley mechanism, and in addition to the first slider 21A and the second slider 22A, the rope 25A and the rope 25A are wound. And a coupling member 27 for coupling the rope 25A and the first slider 21A. The two fixed ends 25a of the rope 25A are fixed at the fixing portion 26 to the cover plate 104, that is, the building. In addition, although the fixing | fixed part 26 is one in this embodiment, the edge part of rope 25A may be fixed with a building by the separate fixing | fixed part 26, respectively. The two pulleys 241 and 242 are rotatably supported around the rotation centers Ax21 and Ax22, respectively, on a support plate 23 which is a part of the second slider 22A. As apparent from FIG. 1, the rotation centers Ax 21 and Ax 22 are both along the vertical direction (vertical direction, vertical direction, vertical direction in FIGS. 1 and 2), and the support plate 23 faces the vertical direction. It extends along a direction intersecting (perpendicular) with the vertical direction, the opening direction Do, and the closing direction Dc. The coupling member 27 is coupled to the first slider 21A on the opposite side of the fixed end 25a with respect to the pulleys 241 and 242. The cover plate 104 is an example of a fixing portion.

  Since the support plate 23 (second slider 22A) is movable along the rail assembly 103 along the opening direction Do and the closing direction Dc, the pulleys 241 and 242 around which the rope 25A is wound function as a moving pulley. Do. Specifically, in FIG. 3, when the first slider 21A and the coupling member 27 move in the opening direction Do along with the movement of the blade 203 in the opening direction Do, the second opening / closing mechanism 20A as a moving pulley mechanism is The moving amount and moving speed of the pulleys 241 and 242 in the opening direction Do, that is, the moving amount and moving speed of the second slider 22A and the second floor door 102A fixed to the pulleys 241 and 242 are the moving amount of the coupling member 27. And the movement speed of the first slider 21A and the first floor door 101A fixed to the coupling member 27 and the movement speed thereof. Therefore, the first floor door 101A located at the first closed position P1c and the second floor door 102A located at the second closed position P2c in FIG. 3 are different from the first opening / closing mechanism 10 (FIG. 1) and the second opening / closing mechanism 20A.

(The first floor door 101A) and the second open position P2o (the second floor door 102A) are reached. The second opening and closing mechanism 20A may also be referred to as a second interlocking mechanism that interlocks the first floor door 101A and the second floor door 102A.

(Third opening and closing mechanism)
6 to 8 are schematic plan views of the floor door opening and closing device 100A, showing the operation of the third opening and closing mechanism 30. FIG. 9 is a perspective view of part of the floor door opening and closing device 100A.

  The third opening and closing mechanism 30 is, for example, when the second opening and closing mechanism 20A becomes inoperable, for example, the rope 25A is cut or detached, or the pulleys 241 and 242 are broken. As a backup, the second floor door 102A is opened and closed according to the opening and closing of the first floor door 101A. The third opening / closing mechanism 30 is configured of a coupling member 27 and a notch 23 a provided in the support plate 23. Specifically, as shown in FIGS. 1, 3, 5, etc., the support plate 23 accommodates the coupling member 27 and extends a notch 23a (opening) along the relative movement direction of the coupling member 27. Is provided. The end on the closing direction Dc side of the coupling member 27 is the first pressing portion 27c, and the edge on the closing direction Dc side of the cutout 23a is the first receiving portion 23c. As shown in FIG. 3, with the first floor door 101A positioned at the first closed position P1c and the second floor door 102A positioned at the second closed position P2c, the first pressing portion 27c and the first receiving portion There is a gap between it and 23c. On the other hand, the end on the opening direction Do side of the coupling member 27 is the second pressing portion 27o, and the edge on the opening direction Do side of the notch 23a is the second receiving portion 23o. As shown in FIG. 5, with the first floor door 101A positioned at the first open position P1o and the second floor door 102A positioned at the second open position P2o, the second pressing portion 27o and the second receiving portion There is a gap between it and 23o.

  In such a configuration, when the first floor door 101A positioned at the first closed position P1c in FIG. 3 moves in the opening direction Do by the operation of the first opening / closing mechanism 10 (FIG. 1), the second floor door In a state where 102A can not be interlocked with the first floor door 101A by the second opening / closing mechanism 20A, only the first floor door 101A moves in the opening direction Do, and the second floor door 102A stays at the second closed position P2c. In this case, as shown in FIG. 6, the first floor door 101A is moved to the first intermediate position P1 m2, and the second pressing portion 27o of the coupling member 27 and the second receiving portion 23o of the notch 23a are in contact with each other. At this point, the pressing of the second receiving portion 23o by the second pressing portion 27o is started, and thereafter, the second floor door 102A follows the first floor door 101A. When the first floor door 101A moves in the opening direction Do and reaches the first opening position P1o, the second floor door 102A also moves in the opening direction Do, and the second opening position P2o by the second opening and closing mechanism 20A shown in FIG. A second open position P2o1 slightly closer to the closing direction Dc than the second opening position P2o1 is reached.

  On the other hand, when the first floor door 101A positioned at the first open position P1o in FIG. 7 is moved in the closing direction Dc by the operation of the first opening / closing mechanism 10 (FIG. 1), the second floor door 102A is the second opening / closing mechanism 20A. Thus, in a state where it can not be interlocked with the first floor door 101A, only the first floor door 101A moves in the closing direction Dc, and the second floor door 102A stays at the second open position P2o1. In this case, as shown in FIG. 8, the first floor door 101A is moved to the first intermediate position P1 m3, and the first pressing portion 27c of the coupling member 27 and the first receiving portion 23c of the notch 23a are in contact with each other. At the time, the pressing of the first receiving portion 23c by the first pressing portion 27c is started, and thereafter, the second floor door 102A follows the first floor door 101A. The second floor door 102A that follows the first floor door 101A moved in the closing direction Dc by the third opening / closing mechanism 30 hits the support arm 106 shown in FIG. 9 before the first floor door 101A reaches the first closed position P1c. Thus, the second closed position P2c is reached. Thereafter, the first floor door 101A moves in the closing direction Dc to reach the first closed position P1c, and is in the state shown in FIG. The support arm 106 is an example of a stopper.

  As described above, in the state of FIG. 3, a gap is provided between the first pressing portion 27c and the first receiving portion 23c, and in the state of FIG. 5, the second pressing portion 27o and the second receiving portion 23o. There is a gap between the In other words, since the coupling member 27 and the support plate 23 move relative to each other, the size (length) of the notch 23 a does not interfere with the coupling member 27 that moves relative to the support plate 23. It is set larger (longer) than the relative movement range (length) of the coupling member 27 in the above. With such a configuration, during normal operation (normal operation) of the second opening / closing mechanism 20A, interference between the first pressing portion 27c and the first receiving portion 23c and between the second pressing portion 27o and the second receiving portion 23o Interference can be suppressed, and application of tension to the rope 25A by these interference can be suppressed. The third opening and closing mechanism 30 is also referred to as a third interlocking mechanism that interlocks the first floor door 101A and the second floor door 102A, and can also be referred to as a backup interlocking mechanism or a failsafe interlocking mechanism.

(Second lock mechanism)

  FIG. 14 is a block diagram of the abnormality determining device 70 of the floor door opening and closing device 100B2. Based on the detection results of the first sensor 71 and the second sensor 72, the abnormality determination device 70 detects an abnormal state of the second opening / closing mechanism 20B, that is, a state in which the second floor door 102B is not interlocked with the first floor door 101B. In addition, control of each part corresponding to the abnormal condition can be executed.

  The first sensor 71 can detect at least one of the first lock state P41 and the first unlock state P4u of the first lock mechanism 40. In the present embodiment, the first sensor 71 is fixed to a building such as the cover plate 104, for example, and conduction is secured by the lock arm 41 in the first locked state P4l, and conducted by the lock arm 41 in the first unlocked state P4u. Can be configured as a contact-type electrical switch that is released. However, the first sensor 71 is not limited to this, and may be, for example, a non-contact sensor or the like.

  The second sensor 72 can detect whether the second floor door 102B is located at the second closed position P2c. In the present embodiment, the second sensor 72 is fixed to a building such as the cover plate 104, for example, and the second slider 62 fixed to the second floor door 102B positioned at the second closed position P2c secures conduction. When the second floor door 102B is separated from the second closed position P2c, the second slider 62 can be configured as a contact-type electrical switch that is de-energized. However, the second sensor 72 is not limited to this, and may be, for example, a noncontact sensor or the like.

  The abnormality determination device 70 includes a control unit 73. The control unit 73 includes an arithmetic processing unit 73a, an output control unit 73b, an elevation control unit 73c, an open / close control unit 73d, and a communication control unit 73e. The arithmetic processing unit 73a determines an abnormality of the second opening and closing mechanism 20B based on the detection results of the first sensor 71 and the second sensor 72. Specifically, when the first lock mechanism 40 is in the first unlock state P4u and the second floor door 102B is positioned at the second closed position P2c, it is determined that the second opening / closing mechanism 20B is abnormal. Do. As described above, when the second opening and closing mechanism 20B is operating normally, in the first unlocking state P4u of the first lock mechanism 40, the second floor door 102B interlocks with the first floor door 101B, and It should move from the two close position P2c. Therefore, based on the detection results (detection signals) of the first sensor 71 and the second sensor 72, the arithmetic processing unit 73a does not perform the second floor door even though the first lock mechanism 40 is in the first unlocked state P4u. It is possible to determine (detect) an abnormal state of the second opening and closing mechanism 20B that the 102B does not move from the second closed position P2c. In addition, you may utilize the time lag (time difference) of the detection result by the 2nd sensor 72 with respect to the detection result by the 1st sensor 71 for abnormality determination. The arithmetic processing unit 73a is an example of the abnormality determination unit.

  The output control unit 73b, such as the display 74 (display output unit) or the speaker 75 (voice output unit), executes a predetermined abnormal output when the arithmetic processing unit 73a determines that the second opening / closing mechanism 20B is abnormal. Control the output unit. Specifically, for example, in the floor or the car 200, the door is opened only on one side, that attention is required when getting on and off, that the opening / closing device is abnormal, urging to get out of the car, The display 74 or the speaker 75 is controlled such that at least one of display output and audio output is performed, such as prohibiting riding. In addition, the output control unit 73b may control an output state (lighting state) of illumination and the like (not illustrated).

  The elevation control unit 73c can control elevation of the car 200 based on the result of the abnormality determination result of the second opening and closing mechanism 20B by the arithmetic processing unit 73a. Specifically, for example, when an abnormality is determined, the lift control unit 73c can control the lift device 81 so that the car 200 does not move from the floor.

  The opening and closing control unit 73d can control the opening and closing of the car door 201 and thus the first floor door 101B based on the result of the abnormality determination of the second opening and closing mechanism 20B by the arithmetic processing unit 73a. Specifically, for example, when an abnormality is determined, the open / close control unit 73d opens the car door 201 once on the premise that the car door 201 is opened at a lower speed than normal or that the car door 201 remains on the floor. The switchgear 82 can be controlled to maintain the open position.

  The communication control unit 73e can control automatic notification and the like based on the result of the abnormality determination of the second opening and closing mechanism 20B by the arithmetic processing unit 73a. Specifically, for example, when an abnormality is determined, the communication control unit 73e transmits a signal indicating that an abnormality has occurred, a signal indicating that maintenance is requested, or the like to the maintenance device or the management device. The communication device 83 can be controlled to do this.

  As described above, in the present embodiment, the arithmetic processing unit 73a can determine the abnormality of the second opening / closing mechanism 20B based on the detection results of the first sensor 71 and the second sensor 72. Therefore, according to the present embodiment, for example, the abnormality determination device 70 can be realized with a relatively simple configuration. Further, according to the present embodiment, for example, the advantages such as the safety can be further improved and the maintenance can be performed more quickly can be obtained.

  Further, as shown in FIG. 1, also in the first embodiment of single opening, by equipping the first sensor 71 and the second sensor 72, it is possible to detect an abnormality of the second opening / closing mechanism 20A. In this case, the second sensor 72 is fixed to a building such as the cover plate 104, for example, and the position of the support plate 23 (second slider 22A) corresponding to the second closed position P2c of the second floor door 102A (FIG. 1) As long as it can be detected.
