In the wheelchair user mode, the door opening time is extended as compared with the normal mode, and the raising / lowering acceleration and raising / lowering speed of the car 5 are kept low in order to increase the landing accuracy of the car 5.

  Next, FIG. 2 is a plan view showing the elevator apparatus when the car 5 of FIG. 1 is landed on the landing floor. FIG. 3 is a side view showing the car 5 and the landing 17 shown in FIG. In the figure, a car operation panel 15 is provided in the car 5.

  The car operation panel 15 includes a car operation panel 15a for general passengers and a car operation panel 15b for wheelchair users. The general passenger car operation panel 15a is provided with a plurality of general passenger car operation buttons 16a which are car side operation buttons. The car operation panel 15b for wheelchair users is provided with a plurality of car side operation buttons 16b for wheelchair users, which are car side operation buttons.

  The wheelchair user's car operation panel 15b is provided mainly for the purpose of being operated by a wheelchair user, and is disposed at a position lower than the general passenger's car operation panel 15a.

  The hall 17 includes a hall entrance 18, an entrance frame (three-sided frame) 19 fixed to both sides and the upper part of the hall entrance 18, a hall operation panel 20 disposed in the vicinity of the hall entrance 18, and a hall that opens and closes the hall entrance 18. Door 21 is provided. The entrance / exit frame 19 has a pair of vertical frames 19a extending vertically and an upper frame 19b provided horizontally between the upper ends of the vertical frames.

  The hall operation panel 20 includes a general passenger hall operation panel 20a and a wheelchair user hall operation panel 20b. The general passenger landing operation panel 20a is provided with a plurality of general passenger landing side operation buttons 22a which are landing side operation buttons. The wheelchair user landing operation panel 20b is provided with a plurality of wheelchair user landing side operation buttons 22b which are landing side operation buttons.

  The wheelchair user landing operation panel 20b is provided mainly for the purpose of being operated by a wheelchair user, similarly to the wheelchair user car operation panel 15b, and is lower than the general passenger landing operation panel 20a. Placed in position.

  The operation of the general passenger car side operation button 16a, the wheelchair user car side operation button 16b, the general passenger landing side operation button 22a, or the wheelchair user landing side operation button 22b is input to the control device 6. Call registration is performed.

  The landing door 21 is engaged with the car door 11 when the car 5 reaches the landing floor. As a result, the landing door 21 is opened and closed in conjunction with the car door 11.

  Between the car door 11 and the landing door 21, a multi-beam sensor (wheelchair user detection sensor) 27 for determining whether a passenger passing through the car doorway 10 and the landing doorway 18 is a wheelchair user. Is arranged. The multi-beam sensor 27 is attached to the car door 11.

  In addition, the multi-beam sensor 27 includes a high-frequency sensor unit 27a and a low-frequency sensor unit 27b in order to determine the height of a passenger entering the car 5.

  The high-frequency sensor unit 27a is for determining whether or not the height of a passenger entering the car 5 is equal to or higher than a predetermined reference height (for example, a height at which a general adult user's neck is positioned). Is. When the passenger passing through the car entrance 10 and the landing entrance 18 is a wheelchair user, the high-frequency sensor unit 27a is arranged so as not to detect the passenger. That is, when the wheelchair user passes through the car doorway 10 and the landing doorway 18, the high-frequency sensor unit 27a does not detect a passenger, and only the low-frequency sensor unit 27b detects a passenger. Signals from the high frequency sensor unit 27 a and the low frequency sensor unit 27 b are input to the control device 6.

  The control device 6 allows a passenger to be controlled by a wheelchair user mode by input from the wheelchair user-side operation button 16b, the wheelchair user landing-side operation button 22b, and the multi-beam sensor 27. When determined, the control mode is switched from the normal mode to the wheelchair user mode. That is, after the wheelchair user landing side operation button 22b is operated, the control device 6 detects only the low-frequency sensor unit 27b, and only when the wheelchair user's car side operation button 16b is operated. In addition, the control mode is switched from the normal mode to the wheelchair user mode.

  Further, the control device 6 does not require the passenger to control in the wheelchair user mode by input from the wheelchair user-side operation button 16b, the wheelchair user landing-side operation button 22b, and the multi-beam sensor 27. If the passenger is determined to be a passenger, the normal mode is maintained. Furthermore, when the high-frequency sensor unit 27a and the low-frequency sensor unit 27b detect a passenger, the control device 6 opens the car door 11 and the landing door 21.

  Next, the operation will be described. FIG. 4 is a flowchart showing a control mode selection operation performed by the control device 6 of FIG. In the figure, when the hall operation panel 20 is operated and hall call registration is performed, it is determined whether or not the call registration is due to the wheelchair user landing side operation button 22b (step S1).

  At this time, if the call registration is based on the general passenger landing side operation button 22a, the passenger is determined to be a passenger who does not need to be controlled in the wheelchair user mode, and the control in the normal mode is maintained.

  On the other hand, if the call registration is based on the wheelchair user landing side operation button 22b, it is determined from the multi-beam sensor 27 whether or not the height of the passenger entering the car 5 is equal to or higher than a predetermined reference height. (Step S2).

  Here, when the passenger boarding the car 5 is a general passenger (adult healthy person), it is considered that the passenger height is equal to or higher than a predetermined reference height, that is, the high frequency sensor unit 27a and the low frequency range. The passenger is detected by both of the sensor units 27b, it is determined that the passenger does not need the control in the wheelchair user mode, and the control in the normal mode is maintained.

  On the other hand, if a passenger is detected only by the low-frequency sensor unit 27b, it is next determined whether or not destination floor registration is performed by operating the wheelchair user-side operation button 16b (step S3). .

  At this time, if the destination floor registration is not performed by the operation of the wheelchair user-side operation button 16b and the destination floor registration is performed by the general passenger landing-side operation button 22a, the passenger is in the wheelchair user mode. It is determined that the passenger does not need control, and control in the normal mode is maintained. Even when the destination floor registration itself is not performed, the control in the normal mode is maintained.

  However, when the destination floor registration is performed by the operation of the wheelchair user-side operation button 16b, the passenger is determined as the passenger who needs the wheelchair user mode, and the control mode is changed from the normal mode to the wheelchair user mode. Can be switched.

  When the control mode is switched from the normal mode to the wheelchair user mode, the vertical acceleration and the vertical speed of the car 5 are suppressed to a low level, so that the floor surface of the car 5 and the floor surface of the landing 17 are landed on the landing floor. The passengers can get on and off safely by reducing the difference in level and extending the door opening time.

  In such an elevator apparatus, the control device 6 responds to inputs from the wheelchair user's car side operation button 16b, the wheelchair user's landing side operation button 22b, and the multi-beam sensor 27, that is, the passenger uses the wheelchair. Since the control mode is switched from the normal mode to the passenger mode only when it is determined that the control in the passenger mode is necessary, the operation of the car 5 and the door opening / closing control are appropriately performed, and the operation efficiency of the elevator apparatus is deteriorated. Can be prevented.

  Further, the control device 6 determines whether the passenger is a passenger who needs to be controlled in the wheelchair user mode based on the signal from the multi-beam sensor 27 whether the passenger's height is equal to or higher than the reference height. Since it judges, control by the mode for wheelchair users is performed even when a passenger is not only a wheelchair user but a child, and a passenger's safety can be improved.

  Furthermore, since the multi-beam sensor 27 is attached to the car doorway 10, that is, the car door 11, it is not necessary to provide it at each landing 17, and it is possible to prevent the cost of the elevator apparatus from increasing.

Embodiment 2. FIG.

That is, the multi-beam sensor 27 is attached to the vertical frame 19 a of the entrance / exit frame 19. Other configurations and operations are the same as those in the first embodiment.

  In such an elevator apparatus, since the multi-beam sensor 27 is provided in the entrance / exit frame 19, when a wheelchair user gets into the car 5, a door closing operation starts in front of him, and the car door 11 and the landing door It is possible to reduce the possibility that a problem such as being caught between the doors 21 occurs. Moreover, when a passenger runs into the car 5 and tries to get in, the door closing operation starts in front of the user and the possibility of occurrence of a problem that the passenger collides with the landing door 21 can be reduced.

  Further, since the multi-beam sensor 27 is attached to the vertical frame 19 a of the entrance / exit frame 19, repair work can be performed at the landing 17 even if a malfunction such as a failure occurs in the multi-beam sensor 27, and maintenance of the multi-beam sensor 27 is performed. Can be improved.

  In the second embodiment, the multi-beam sensor 27 is attached only to the landing entrance 18, that is, the vertical frame 19 a of the entrance / exit frame 19. However, the wheelchair user detection sensor is provided at both the car entrance and the entrance / exit. May be.

  In the first and second embodiments, the multi-beam sensor 27 is used as the wheelchair user detection sensor. However, the wheelchair user detection sensor is configured such that the control device 6 detects the car operation panel, the landing operation panel, and the wheelchair user. The control mode may be switched according to information from the sensor, and the sensor is not limited to the multi-beam sensor, and any sensor that can detect a wheelchair user may be used.
