次に、上記のように構成された従来のエレベータの扉
装置の動作を説明する。Next, the operation of the conventional elevator door device configured as described above will be described.
エレベータかご9が昇降するときには、乗場扉3及び

示すように間隙Gが形成されている。When the elevator car 9 moves up and down, the hall door 3 and the elevator car door 11 are fully closed, and the elevator car door 11
The engaging plate 13 and the engaging plate 14 are respectively the engaging elements 8 of the landing door 3.
And away from the engaging element. That is, when the elevator car 9 passes through the landing, the elevator 7, the engager 8, the engage plate 13, and the engage plate 14 can travel without coming into contact with each other. At this time, a gap G is formed between the engagement element 8 and the engagement plate 13 as shown in FIG.
次に、エレベータかご9が乗場に着床すると、駆動機

15 rotates and elevator car door 11 via link mechanism 17
Is opened. At this time, the engagement plate 14 rotates and the engagement plate 1
3, the engaging plate 14 contacts the engaging elements 8 and 7, respectively, and holds them. Then, in this state, the elevator car door 11 moves in the door opening direction, so that the hall door 3 also moves in the door opening direction in conjunction with this.

の係合は解除される。On the contrary, when the door is closed from the open state, the operation is opposite to the above, and the hall door 3 also moves in the door closing direction in conjunction with the movement of the elevator car door 11, and the elevator car door 11 and the hall door 3 When is completely closed, the engagement plate 14 is rotated via the link mechanism 17 to release the engagement between the engagement plate 13 and the engagement element 8 and between the engagement plate 14 and the engagement element 7.

16の出力回転距離、回転速度により制御される。By the way, in order to start the door, after the elevator car door 11 moves through the gap G between the engaging element 8 and the engaging plate 13, the engaging plate 13 contacts the engaging element 8 and the hall door 3 starts to open. At this time, a collision sound is generated when the engagement plate 13 contacts the engagement element 8.
In order to suppress this collision noise and maintain quietness when the door is opened, it is necessary to open the elevator car door 11 at a low speed before and after the collision. On the other hand, when the door is closed, the hall door 3 precedes the elevator car door 11 by the gap G to complete the door closure.
At this time, in order to suppress the noise that the hall door 3 collides with the contact surface of the entrance / exit 2 of the hall, it is necessary to close the door at a low speed from the front by at least the length G before fully closing. Therefore, the opening / closing speed of the elevator car door 11 is an encoder directly connected to the rear shaft end of the drive machine 15 according to the speed patterns shown in FIGS. 8 and 9.
It is controlled by 16 output rotation distance and rotation speed.

開閉ができなかった。[Problems to be Solved by the Invention] Since the conventional elevator door device is configured as described above, the gap G between the engagement plate 13 and the engagement element 8 is preferably narrow in terms of door opening / closing performance. It is desirable to be able to open and close quickly, but
When it becomes narrow, the engagement plate 13, the engagement plate 14 and the engagement element 8, the engagement element 7
May collide with. In addition, there are variations in the installation positions of the engaging elements 7 and 8 on each floor, and the size of the gap G differs depending on each floor. Therefore, in the opening / closing pattern of the door in FIGS. 8 and 9, it is necessary to set the low speed traveling range of C in FIG. 8 and D in FIG. 9 in consideration of the maximum value of the variation in the gap G. .
For this reason, the low-speed traveling range becomes long, the opening and closing time of the door becomes long, and the operating rate of the elevator decreases. On the contrary, when the low-speed travel area is shortened, the collision speed between the engagement plate 13 and the engagement element 8 when the door is opened and the collision speed between the landing door 3 and the contact surface of the doorway 2 of the landing when the door is closed are increased. A collision noise was generated, and it was impossible to open and close the door quietly.

易な駆動装置によって未然に防止するものである。This technique is provided with a drive device for driving the door of the hall just before the fully closed position in the door closing direction and an operation command device for operating the door when abnormal running resistance such as wind pressure acts on the door of the hall. It is designed to drive the doors of the landing hall fully closed against the running resistance, which causes the elevator door operation failure because the hall doors do not fully close due to abnormal running resistance such as wind pressure from the position just before full closing. This is prevented by a simple drive device that drives the landing door, which is in a disengaged state with the car door from immediately before the fully closed position, to the fully closed position.
しかし、この技術は、係合板と係合子が衝突するもの

開閉ができなかった。However, in this technology, the engagement plate and the engagement element collide with each other, and when the door is opened and closed, the collision speed between the landing door and the contact surface of the entrance and exit of the landing is increased, and a collision noise is generated, resulting in a quiet door. I couldn't open or close.

A landing door provided with a predetermined gap and arranged on both sides, and an engaging member projecting from the elevator car door that abuts the engagement plate when the elevator car door is opened and closed; and the engagement plate and the landing door of the elevator car door. A detector for detecting the size of the gap with the engaging element, and the gap between the engaging plate of the elevator car door and the engaging element of the landing door is determined according to the amount detected by the detector. When decreasing, the opening / closing speed of the elevator car door is controlled according to a door opening / closing speed pattern.

Depending on the output of this detector, the minimum noise required to suppress the collision noise between the engagement element and the engagement plate when the door is opened and the collision noise between the landing door and the contact surface of the entrance and exit of the landing when the door is closed. The low-speed running range of the door is obtained for each floor, and the opening / closing speed is controlled according to this door opening / closing speed pattern. As a result, the door can be quietly opened and closed, and the low speed traveling range can be suppressed to the required minimum, so that the opening and closing speed can be increased.

開閉を行なうことができる。[Effects of the Invention] As described above, the elevator door apparatus of the present invention determines the size of the gap between the engagement plate of the elevator car door that is fixed so as to project toward the entrance / exit side of the hall and the engaging element of the hall door. A door that slows the opening / closing speed of the elevator car door when the distance between the engaging plate of the elevator car door and the engaging member of the landing is decreased according to the amount detected by the detector. Since it is controlled by the speed control means according to the opening / closing speed pattern, when the door is opened according to the value of the gap between the engaging member of the hall door and the engaging plate of the elevator car door detected by the detector for each floor. It is possible to set a minimum required low speed traveling range of the door for suppressing the collision sound between the engaging element and the engaging plate and the collision sound between the landing door and the contact surface of the entrance and exit of the landing when the door is closed. Therefore, the door can be opened and closed quietly and quickly.
