  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows an overall configuration of an elevator apparatus according to an embodiment of the present invention. In the elevator apparatus according to this embodiment, a wheelchair operator panel 4 is installed on the inner wall surface of the car 12. The wheelchair operation panel 4 is provided in the same operation panel as the in-car operation panel for the healthy person, or is provided independently of the in-car operation panel for the healthy person. On the floor 5 of the car 12, a plurality of small pressure detection elements, that is, pressure sensors 9, are uniformly arranged on one surface. The pressure sensor 9 is connected to the pressure distribution analyzing means 8 and further connected to the in-car user determining means 6. Further, the pressure distribution analyzing means 8 is also connected to the door opening extension calculating means 7. The in-car user determining means 6 and the door opening extension calculating means 7 are connected to the elevator control panel 1 via the tail cord 2, respectively. The load of the wheelchair user and the wheelchair 10 that has entered the car 12 is transmitted to the pressure distribution analysis means 8 by the pressure signals measured by the plurality of pressure sensors 9 provided on the floor 5 via the wheels 11 of the wheelchair 10. Input and detected as pressure distribution on the floor.

  FIG. 2 shows the pressure distribution with respect to the wheelchair user when the wheelchair user gets into the car 12 and the pressure sensors 9 arranged on the floor 5 and the plurality of pressure sensors 9 via the wheels 11 of the wheelchair 10 under the load of the wheelchair 10. . As shown in FIG. 2, the pressure distribution on the floor 5 is high near the center of the wheel 11, and the pressure decreases as the distance from the center of the wheel 11 increases. Here, the load on the floor 5 of the wheel 11 is detected as a pressure distribution peculiar to the wheel, such as a shape (arc shape) that is elongated and has a curvature R as viewed from the surface of the floor 5 according to the shape of the wheel 11. . Thereby, the presence / absence of the wheel 11 of the wheelchair 10 in the car 12 is detected. In the present embodiment, a plurality of pressure sensors 9 are evenly provided on the floor 5, and the pressure received from the wheels 11 can be detected more accurately. Based on this pressure distribution information, the in-car user judging means 6 discriminates whether the wheelchair user or the user of the transportation cart gets into the car, and sends this judgment result to the control panel 1. The control panel changes the door opening time and opening / closing speed based on this.

  FIG. 3 shows a wheel contact portion and a wheel locus on the floor surface of the elevator apparatus according to the present embodiment. As shown in FIG. 3, the pressure distribution analysis means 8 continuously monitors the movement locus of the pressure distribution from the time when the detected object having the wheels 11, that is, the load of the wheelchair user and the wheelchair 10 is detected. When the destination floor is registered by the wheelchair operator panel 4 and the door is opened after landing on the destination floor, the door opening extension calculating means 7 uses the movement trajectory by the initial movement of the wheelchair or the transport carriage to get off the car 12. The travel time is predicted from the travel direction and speed, and the distance to the door, and the optimal door opening extension time is calculated. The calculation result is transmitted to the control panel 1 to change the opening time of the door 3.

  FIG. 4 shows a floor pressure detection and operation control flow of the elevator apparatus in the present embodiment. Wheelchair-only operation is effective when the wheelchair or transfer cart is judged and the wheelchair user or transfer cart user operates the wheelchair operator panel 4, and the door opening extension and door opening / closing speed are normal. Will be slower. Further, the door opening extension time is set to a time optimized by the predicted movement time of the detected object, that is, the wheelchair or the carriage for transportation. On the other hand, when there is no detection of the wheelchair or the carriage for transportation by the pressure sensor 9 installed on the floor 5 of the car 12, that is, when the elevator user is only a healthy person, even if the wheelchair operator panel 4 is operated, the wheelchair operation panel 4 is dedicated. Driving will not be effective.

  As described above, when a wheelchair or a carriage for carriage gets into the elevator car by the elevator apparatus in this embodiment, the wheel shape and the continuous linear shape are detected by the pressure distribution detection by the pressure sensor on the car floor surface. By detecting the movement trajectory, it is possible to determine whether the wheelchair or the carriage for carriage has entered, and only by operating the wheelchair operation panel, the door open extension function is enabled. A decrease in operating efficiency can be prevented. In addition, by continuously monitoring the pressure distribution on the floor in the car, it is possible to predict the time from the moving direction and speed of the wheelchair or transport carriage to the door arrival, and to optimize the door opening time. It is possible to improve convenience for wheelchair users or transport cart users.
