BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 is a top view schematically showing a landing door opening / closing control device according to Embodiment 1 of the present invention. FIG. 2 is an enlarged side view of the landing door opening / closing control device shown in FIG. 1 as viewed from the landing door side.

As shown in FIGS. 1 and 2, a recess 7 in a three-way frame 6 of an elevator hall, which is a fixed end around the hall door 1, is provided.
, A landing door opening / closing control device 10 is provided. The landing door opening / closing control device 10 includes, as load supply means, an arm 11 that is a movable portion, and an arm base 13 that supports the arm 11 on a shaft 12. The arm 11 is pivotally supported on the arm base 13 by utilizing the principle of leverage at a position shifted from the center in the longitudinal direction, and includes a roller 14 at a long end when viewed from the shaft 12. The roller 14 is supported by the arm 11 so as to rotate with some resistance.

Further, the arm base 13 includes a spring 15 and an electromagnet 16 as a movable part pressing control mechanism. Spring 15
Is provided so as to be connected to the side of the arm 11 where the roller 14 is supported when viewed from the shaft 12.
Is provided on the opposite side of the shaft 15 with respect to the spring 15. In addition, as shown in FIG. 1, when the roller 14 does not press the landing door 1, the spring 15 is in a contracted state. When the arm 11 is not pressing the landing door 1 as shown in FIG. 1, the electromagnet 16 is demagnetized, and the arm 11 is at the position shown in the figure due to the contraction force of the spring 15.

FIG. 3 is a front view schematically showing a configuration around a switch of the landing door opening / closing control device 10. As shown in FIG. FIG.
It is a top view which shows the state which the opening / closing control device 10 of the landing door is operating. FIG. 5 is a circuit diagram schematically showing a configuration of a timer for controlling the energization of the electromagnet.

In FIG. 3, a switch 17 serving as a door unlocking signal generating means is turned on by an operator unlocking the landing door 1 using an unlocking bar 19 for elevator maintenance work, and the switch 17 is turned on. This is a switch for exciting the electromagnet 16 by the generated door unlock signal. In order to demagnetize the electromagnet 16, an operator manually operates the switch 17.
Must be cut.

As shown in FIG. 4, when the electromagnet 16 is excited, the arm 11 is urged by the magnetic attraction force in the direction opposite to the contraction force of the spring 15, and the roller 14 presses the landing door 1. At this time, since the arm 11 is pivotally supported on the arm base 13 using the leverage principle, the roller 14
The landing door 1 is actually pressed by a force greater than the magnetic attraction generated by the electromagnet 16.

As shown in FIG. 5, the electromagnet 16 and the switch 17 are provided with a predetermined time (for example, 5 minutes) after the elevator is switched to the automatic operation mode (mode in which the user can use the elevator). A timer 18 for cutting off the power supply to the electromagnet 16 is provided. Timer 18
Is a timer switch 1 for causing the timer to start accumulating time when the elevator is switched to the automatic operation mode.
8a.

Therefore, when the roller 14 pivotally supported by the tip of the arm 11 presses the landing door 1, even if an operator tries to open and close the landing door 1, the roller 14 having rotational resistance is turned on the landing door 1. Rotate the pressing surface. For this reason, the rotation resistance of the roller 14 becomes a load on the landing door 1 that opens and closes, and it is possible to prevent the landing door 1 from opening and closing rapidly, so that a worker who tries to open and close the landing door 1 during elevator maintenance work. Can be prevented from losing posture.

Also, even if a worker forgets to turn off the switch 17 after maintenance work and the elevator is switched to the automatic operation mode, the timer 18 automatically turns off the switch 17 after a certain period of time. There is no hindrance.
