That is, the first floor door 101A is movably supported by the rail assembly 103 via the first slider 21A, and the second floor door 102A is movably supported by the rail assembly 103 via the second slider 22A. Yes. The rail assembly 103 is fixed to a cover plate 104 that is fixed to the building and does not move relative to the floor. The rail assembly 103 does not need to be shared by the first slider 21A and the second slider 22A, and may be provided separately by the first slider 21A and the second slider 22A. Note that both the first slider 21A and the second slider 22A can also be referred to as door hangers.

(First lock mechanism)
A first locking mechanism 40 is provided on the first slider 21A. The first lock mechanism 40 includes a lock arm 41 (latch) supported by the first slider 21A so as to be rotatable about the rotation center Ax1, and two rollers 42o and 42c provided on the lock arm 41. Yes. The claw at the tip of the lock arm 41 is engaged with the hook 105 fixed to the building in the first locked state P41 shown in FIG. In the first locked state P41, the first slider 21A and hence the first floor door 101A cannot move from the first closed position P1c in the opening direction Do. Further, when the lock arm 41 rotates around the rotation center Ax1 in the direction of the curved arrow (clockwise direction) in FIG. 1, the engagement between the hook at the tip of the lock arm 41 and the hook 105 is released, and the first lock mechanism 40 In the first unlocked state (not shown), the first slider 21A and thus the first floor door 101A can move in the opening direction Do from the first closed position P1c. That is, the first locking mechanism 40 is in the first locked state P41 that locks the first slider 21A and the first floor door 101A to the first closed position P1c, and to the first closed position P1c of the first slider 21A and the first floor door 101A.

The door machine 204 drives the car door 201 to open and close. The car door 202 opens and closes in conjunction with the car door 201. The blade 203 extending in the vertical direction is fixed to the car door 201 and moves in the opening direction Do and the closing direction Dc in conjunction with the car door 201. When the car 200 arrives at the floor, the blade 203 is positioned between the two rollers 42o and 42c. When the car door 201 moves from the closed position shown in FIG. 2 in the opening direction Do, the blade 203 moves the roller 42o of the first lock mechanism 40 around the rotation center Ax1 in the direction of the curved arrow (clockwise direction) in FIG. Thereby, the first lock mechanism 40 shifts from the first lock state P41 to the first unlock state. On the other hand, when the car door 201 moves from the open position (not shown) in the closing direction Dc, the blade 203 pushes the roller 42c of the first lock mechanism 40, whereby the claw of the lock arm 41 gets over the hook 105 and Engage with the hook 105 and enter the first locked state P4l. That is, the first lock mechanism 40 enters the first locked state P4l in which the first floor door 101A is locked at the first closed position P1c by the movement of the car door 201 to the closed position, and the first lock mechanism 40 is moved by the movement from the closed position of the car door 201. It will be in the 1st unlocked state which cancels | releases the lock | rock to the 1st closed position P1c of 101 A of doors.

(First opening / closing mechanism)
When the roller 42o is pushed by the blade 203 moving in the opening direction Do, the first slider 21A and the first floor door 101A move in the opening direction Do. 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 42o and 42c function as the first opening / closing mechanism 10 that opens and closes the first floor door 101A according to the opening / closing of the car door 201. The first opening / closing mechanism 10 can also be referred to as a first interlocking mechanism that interlocks the car door 201 and the first floor door 101A.

(Second opening / closing mechanism)
3 to 5 are schematic plan views of the floor door opening / closing device 100A, and are diagrams illustrating the operation of the second opening / closing mechanism 20A. The second opening / closing mechanism 20A that opens and closes the second floor door 102A in response to opening and closing of the first floor door 101A is a moving pulley mechanism, and the rope 25A and the rope 25A are wound in addition to the first slider 21A and the second slider 22A. Two pulleys 241 and 242 and a connecting member 27 that connects the rope 25A and the first slider 21A. The two fixed ends 25 a of the rope 25 </ b> A are fixed to the cover plate 104, that is, the building at the fixing portion 26. In addition, although the fixing | fixed part 26 is one in this embodiment, the edge part of rope 25A may be fixed to a building by the separate fixing | fixed part 26, respectively. The two pulleys 241 and 242 are supported by the support plate 23 which is a part of the second slider 22A so as to be rotatable around the rotation centers Ax21 and Ax22, respectively. As is clear from FIG. 1, the rotation centers Ax21 and Ax22 are all along the vertical direction (the vertical direction, the vertical direction, the vertical direction in FIGS. 1 and 2), and the support plate 23 faces the vertical direction. It extends along a direction intersecting (orthogonal) with the vertical direction, an opening direction Do, and a 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 fixed part.

  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. To do. Specifically, in FIG. 3, when the first slider 21 </ b> A and the coupling member 27 move in the opening direction Do as the blade 203 moves in the opening direction Do, the second opening / closing mechanism 20 </ b> A as the 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 moving speed, that is, the moving amount and moving speed of the first slider 21 </ b> A and the first floor door 101 </ b> A fixed to the coupling member 27. Therefore, in FIG. 3, 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 are connected to the first opening / closing mechanism 10 (FIG. 1) and the second opening / closing mechanism 20A. The first opening position P1o shown in FIG. 5 passes through the first intermediate position P1m1 (first floor door 101A) and the second intermediate position P2m (second floor door 102A) shown in FIG. Reach the (first floor door 101A) and the second open position P2o (second floor door 102A). The second opening / closing mechanism 20A can also be referred to as a second interlocking mechanism that interlocks the first floor door 101A and the second floor door 102A.

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

  For example, when the second opening / closing mechanism 20A becomes inoperable, such as when the rope 25A is cut or disconnected, or the pulleys 241 and 242 are broken, the third opening / closing mechanism 30 is 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 by 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 along the relative movement direction of the coupling member 27 (opening). Is provided. The end of the coupling member 27 on the closing direction Dc side is the first pressing portion 27c, and the edge of the notch 23a on the closing direction Dc side is the first receiving portion 23c. As shown in FIG. 3, in a state where the first floor door 101A is positioned at the first closed position P1c and the second floor door 102A is positioned at the second closed position P2c, the first push portion 27c and the first receiving portion It faces 23c with a gap. 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, in the state where the first floor door 101A is located at the first open position P1o and the second floor door 102A is located at the second open position P2o, the second push portion 27o and the second receiving portion. It faces 23o with a gap.

  In such a configuration, when the first floor door 101A located 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 cannot 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 remains in the second closed position P2c. In this case, as shown in FIG. 6, the first floor door 101A moves to the first intermediate position P1m2, and the second pressing portion 27o of the coupling member 27 and the second receiving portion 23o of the notch 23a come into contact with each other. At that time, the second pressing portion 27o starts to press the second receiving portion 23o, 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 to reach 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 / closing mechanism 20A shown in FIG. It reaches the second open position P2o1 slightly further away in the closing direction Dc side.

  On the other hand, when the first floor door 101A located 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 moved to the second opening / closing mechanism 20A. Thus, in a state where it cannot 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 remains at the second open position P2o1. In this case, as shown in FIG. 8, the first floor door 101A moves to the first intermediate position P1m3, and the first pressing portion 27c of the coupling member 27 and the first receiving portion 23c of the notch 23a come into contact with each other. At the time, the first pressing portion 27c starts to press the first receiving portion 23c, and thereafter, the second floor door 102A follows the first floor door 101A. The second floor door 102A following 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, reaches the first closing position P1c, and enters 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 are provided. There is a gap between them. 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. Is set larger (longer) than the relative movement range (length) of the coupling member 27 at. With such a configuration, during the normal operation (normal operation) of the second opening / closing mechanism 20A, the interference between the first pressing portion 27c and the first receiving portion 23c and the contact between the second pressing portion 27o and the second receiving portion 23o. Interference can be suppressed, and tension applied to the rope 25A due to these interferences can be suppressed. The third opening / closing mechanism 30 may be referred to as a third interlocking mechanism that interlocks the first floor door 101A and the second floor door 102A, and may also be referred to as a backup interlocking mechanism or a failsafe interlocking mechanism.

(Second locking mechanism)

The second unlocked state is released to release the lock. Specifically, the second lock mechanism 50A includes a first pressing portion 27c as an end portion in the closing direction Dc of the coupling member 27 and an edge in the closing direction Dc of the support plate 23 facing each other with a gap in FIG. And a first receiving part 23c as a part. When the first lock mechanism 40 is in the first locked state, the coupling member 27 remains in the position (closed position) in FIG. 3, so that the first pressing portion 27 c moves the first receiving portion 23 c in the opening direction Do. As a result, the movement of the second slider 22A and the second floor door 102A in the opening direction Do is suppressed.

  As described above, in the present embodiment, the third opening / closing is performed by the notch 23a provided in the support plate 23 that supports the pulleys 241 and 242 and the coupling member 27 that couples the rope 25A and the first slider 21A. A mechanism 30 and a second lock mechanism 50A are configured. Therefore, according to the present embodiment, for example, the third opening / closing mechanism 30 and the second lock mechanism 50A are realized with a relatively simple configuration by using the support plate 23 and the coupling member 27 provided close to each other. As a result, the number of parts can be reduced, and the manufacturing cost and labor can be reduced.

  In the present embodiment, the coupling member 27 is provided with a first pressing portion 27c and a second pressing portion 27o. Therefore, according to the present embodiment, for example, in the third opening / closing mechanism 30, the first pressing portion 27c that presses the first receiving portion 23c when the door is closed and the second pressing portion 27o that presses the second receiving portion 23o when the door is open. As compared with the configuration in which the and are separately provided, the number of parts can be reduced, and the manufacturing cost and labor can be reduced.

  Moreover, in this embodiment, the 1st receiving part 23c and the 2nd receiving part 23o can be provided by the notch 23a provided in the support plate 23. FIG. Therefore, according to the present embodiment, for example, the first receiving portion 23c and the second receiving portion 23o are relatively simple compared to the case where the first receiving portion 23c and the second receiving portion 23o are provided by protrusions or the like. It can be realized as a configuration, and as a result, the number of parts can be reduced, and the manufacturing cost and labor can be reduced.

Specifically, when the first locking mechanism 40 is in the first unlocked 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. To do. As described above, when the second opening / closing mechanism 20B is operating normally, in the first unlocked state P4u of the first locking mechanism 40, the second floor door 102B is interlocked with the first floor door 101B, It should move from the two-closed position P2c. Therefore, the arithmetic processing unit 73a is based on the detection results (detection signals) of the first sensor 71 and the second sensor 72, although the first lock mechanism 40 is in the first unlocked state P4u. An abnormal state of the second opening / closing mechanism 20B that the 102B does not move from the second closed position P2c can be determined (detected). For the abnormality determination, a time lag (time difference) of the detection result by the second sensor 72 with respect to the detection result by the first sensor 71 may be used. The arithmetic processing unit 73a is an example of an abnormality determination unit.

  The output control unit 73b, such as the display 74 (display output unit) and the speaker 75 (sound output unit), executes a predetermined abnormality output when the arithmetic processing unit 73a determines abnormality of the second opening / closing mechanism 20B. Control the output section. Specifically, for example, on the floor or in the car 200, the door opens only on one side, needs attention when getting on and off, an abnormality has occurred in the switchgear, prompts the car to get off, The display 74 or the speaker 75 is controlled so that at least one of display output and audio output, such as prohibiting the ride, is executed. Further, the output control unit 73b may control an output state (lighting state) in an illumination (not shown) or the like.

  The raising / lowering control part 73c can control raising / lowering of the cage | basket 200 based on the abnormality determination result of the 2nd opening / closing mechanism 20B by the arithmetic processing part 73a. Specifically, for example, if an abnormality is determined, the lifting control unit 73c can control the lifting device 81 so that the car 200 does not move from the floor.

  The opening / closing control unit 73d can control the opening / closing of the car door 201, and thus the first floor door 101B, based on the abnormality determination result of the second opening / closing mechanism 20B by the arithmetic processing unit 73a. Specifically, for example, when an abnormality is determined, the opening / closing control unit 73d opens the car door 201 once on the assumption that the car door 201 opens at a lower speed than normal or stays on the floor. The opening / closing device 82 can be controlled so as to keep it open.

  The communication control unit 73e can control automatic notification and the like based on the abnormality determination result of the second opening / 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 required, or the like to the maintenance device or the management device. As a result, the communication device 83 can be controlled.

  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, it is possible to obtain an advantage that safety can be further improved and maintenance can be performed more quickly.

  Further, as shown in FIG. 1, also in the first embodiment of the one-side opening, by providing 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). Can be detected.
