設けられていた。2. Description of the Related Art As a countermeasure against an accident in which the hands of an infant or a child are pulled into an elevator car door, for example, the actual construction of Sho 58-
No. 67874 discloses an abnormality detecting device for elevator doors. 5 and 6 show the configuration of this conventional device. As shown in these figures, the elevator car door has two doors, that is, the car first door 1 and the car second door.
When the door 2 is opened, the basket first door 1 and the basket second door 2 move in the direction shown by the arrow in FIG.
It is stored in the shadow of. At this time, if the hands 3 of the infant / child are in contact with the first door 1 of the basket, there is a risk of causing a serious injury accident. In order to prevent such a serious human injury accident, the conventional device has a mechanism as shown in FIG.

きる。That is, for example, the end portion 2a of the second car door 2
Is a movable part, and the switch 4 is turned on when the hand 3 is touched. More specifically, the second basket 2
End 2a of the basket can be rotated inside the second door 2 of the basket,
The second door 2 of the car is provided with a hinge 5. When the first basket door 1 moves in the direction of the arrow in FIG. 6, the hand 3 in contact with the first basket door 1 also moves in the direction of the arrow. When the hand 3 contacts the end portion 2a, the tip of the end portion 2a rotates inside the second basket door 2 and contacts the switch 4. When the tip of the end portion 2a of the second basket door 2 comes into contact with the switch 4 and the switch 4 is turned on, a predetermined abnormality treatment operation is executed in response to this. By providing such a mechanism,
It is possible to prevent the accident in which the hand 3 is retracted from expanding.

Therefore, even if the hand of an infant, child, etc. is in contact with the elevator door, more specifically, the basket door panel covering the surface of the elevator door immediately before the door is opened, the door door will be urged to open the door soon. Since a warning is given, an accident in which a hand or the like is drawn into a gap between the basket door panel and another door or door pocket is effectively prevented. Further, in the present invention, the basket door panel is biased inward at least when the door is opened, and a gap is secured between the basket door panel and another door or door pocket. That is, as described above, the gap between the basket door panel and other doors or door pockets is closed to prevent accidents during the period when the door can be considered to open soon, but at the time when the door is about to open, there is a gap. As a result, the door opening operation becomes smooth.

応じて電磁石１０の励磁動作を制御する手段である。As shown in these drawings, in this embodiment, a car door panel 8 is provided so as to cover the surface of the second car door 2. Inside the basket second door 2, a spring 9 that constantly urges the basket door panel 8 toward the inside of the basket second door 2, and the basket door panel 8 toward the outside of the basket second door 2 in response to excitation. Energizing electromagnet 10 and plunger 11
Is provided. It is preferable that a plurality of springs 9, electromagnets 10 and plungers 11 are provided at appropriate intervals so that the basket door panel 8 is uniformly biased. The control unit 12 is means for controlling the exciting operation of the electromagnet 10 according to the traveling state of the elevator and the opening / closing state of the car door.

ル８と柱７の隙間６は０ｍｍとなる。As shown in this figure, when it can be considered that the elevator car door will soon open (100), the control unit 12 excites the electromagnet 10 (101). Electromagnet 1
In the state before 0 is excited, as shown in FIG. 2, only the urging force of the spring 9 acts, so that a gap 6 is formed between the second basket door 2 and the pillar 7. The gap 6 is, for example, about 5 to 6 mm. When the electromagnet 10 is energized by the controller 12, as shown in FIG. 3, the plunger 10 is responsive to the magnetic flux generated by the electromagnet 10.
Slides, and the basket door panel 8 is biased against the biasing force of the spring 9 toward the outside of the second basket door 2, that is, downward in the figure. Thereby, a gap 13 of about 5 to 6 mm is generated between the basket door panel 8 and the second basket door 2, and the gap 6 between the basket door panel 8 and the pillar 7 is 0 mm.

制御部１２の動作はステップ１００に戻る。After this, when the timing to open the car door is reached (102), the control section 12 releases the excitation of the electromagnet 10 (103). Then, as shown in FIG. 2, the basket door panel 8 is in a state of being biased only by the spring 9, so that the gap 13 between the second basket door 2 and the basket door panel 8 is formed.
Is 0 mm, and the gap 6 between the car door panel 8 and the pillar 7 is 5
It is about 6 mm. After this, when the basket door actually opens,
The operation of the controller 12 returns to step 100.
