  The interlock 20 includes a movable piece 20a and a fixed piece 20b. The movable piece 20a is provided on one front end side of the door hanger 13. The fixed piece 20b is provided on the other front end side of the door hanger 13. The movable piece 20a and the fixed piece 20b maintain the pair of landing doors 4 in a closed state.

  For example, the operating body 21 is an unlocking lever. For example, the operating body 21 is provided on one door pocket side of the hall door 4.

  The frame 22 is formed in a square shape. The frame 22 is provided on the front end side of one lower part of the hall door 4. The stopper 23 is provided so as to be vertically movable with respect to the frame 22. The stopper 23 includes a knob 23a. The knob 23a is provided on the hoistway 1 side at the center of the stopper 23.

  The latch 24 is provided on the frame 22. The latch 24 is provided on one front end side of the hall door 4 with respect to the stopper 23. The latch 24 is rotatably provided with respect to the frame 22 with the upper portion as a fulcrum. The lower part of the latch 24 keeps the stopper 23 arranged above the hole 12 of the groove 10 of the landing sill 9. One side of the spring 25 is fixed to the frame 22. The other side of the spring 25 is fixed to the lower portion of the latch 24. The spring 25 pulls the lower portion of the latch 24 toward the stopper 23.

  One side of the first wire 26 is connected to the movable piece 20a of the interlock 20. The other side of the first wire 26 is connected to the operating body 21. One side of the second wire 27 is connected to the operating body 21. The other side of the second wire 27 is connected to the upper portion of the latch 24.

  When the car door 5 (not shown in FIG. 2) starts to open during normal operation of the elevator, the movable piece 20a of the interlock 20 is released from the fixed piece 20b. As a result, the hall door 4 is released from the closed state. After that, the hall door 4 follows the car door 5 and opens. At this time, the lower part of the hall door 4 is guided to the groove 10 of the hall threshold 9.

Next, a procedure for inspecting the elevator will be described with reference to FIGS. 3 and 4.
3 and 4 are front views of the elevator door device according to Embodiment 1 of the present invention when viewed from the hoistway side.

  As shown in FIG. 3, when the operator operates the operating body 21 using a special piece (not shown) from the side of the hall 2 (not shown in FIG. 3) during inspection of the elevator, the first wire 26 is pulled. The movable piece 20a of the interlock 20 is released from the fixed piece 20b by being pulled by the first wire 26. As a result, the hall door 4 is released from the closed state.

  At this time, the operating body 21 also pulls the second wire 27. The latch 24 is rotated by being pulled by the second wire 27 with the upper portion as a fulcrum. As a result, the lower portion of the latch 24 is disengaged from the stopper 23. Therefore, the stopper 23 is released from the state in which it is arranged above the hole 12 of the groove 10 of the hall threshold 9.

  At this time, as shown in FIG. 4, the stopper 23 moves downward due to its own weight. At this time, the stopper 23 smoothly moves along a guide (not shown) of the frame 22. As a result, the lower portion of the stopper 23 enters the hole 12 of the groove 10 of the hall sill 9. At this time, the upper portion of the stopper 23 is caught on the upper edge of the frame 22. Therefore, the stopper 23 stops moving in the vertical direction.

  When an operator tries to open the hall door 4 in this state, the lower portion of the stopper 23 comes into contact with the rear edge portion of the hole 12 of the groove 10 of the hall sill 9. As a result, the landing door 4 does not open beyond a preset width. For example, the width at this time is set to 100 mm to 200 mm.

  In this state, the operator confirms the position of the car 3 from the hall 2 side. When the position of the car 3 is appropriate, the operator pulls up the stopper 23 by holding the knob 23a from the landing 2 side. As a result, the stopper 23 is caught on the lower portion of the latch 24. At this time, the operator reconfirms the position of the car 3 from the side of the hall 2. After that, the worker further opens the landing door 4. After that, the worker gets on the car 3.

  According to the first embodiment described above, the stopper 23 prevents the landing door 4 from opening beyond the preset width when the elevator is inspected. Therefore, the position of the car 3 can be confirmed by an appropriate method before getting on the car 3.

  Further, when the stopper 23 is released from the state of being disposed above the hole 12 of the groove 10 of the hall sill 9, the stopper 23 enters the hole 12 of the groove 10 of the hall sill 9 by its own weight. Therefore, the position of the car 3 can be confirmed by an appropriate method with a simple configuration.

  Further, the release of the stopper 23 is interlocked with the operation of the operating body 21 when releasing the latch 24. Therefore, the position of the car 3 can be confirmed by an appropriate method without requiring the operator to perform a special operation.

  The position of the stopper 23 may be determined according to the position of the hole 12 of the groove 10 of the hall sill 9, for example, when a plurality of holes 12 are formed in the groove 10 of the hall sill 9, a plurality of holes 12 are formed. The position of the stopper 23 may be determined according to the position of any one of the holes 12. At this time, the position of the stopper 23 may be determined according to the width when the hall door 4 is opened.

  Further, when the operating body 21 directly moves the movable piece 20a of the interlock 20, the first wire 26 is unnecessary. Also in this case, pulling the latch 24 with the second wire 27 can prevent the hall door 4 from opening beyond a preset width.

  Note that the control device 8 may be used to notify the notification device 6 of information that prompts confirmation of the position of the elevator car 3 according to the operation of the operation body 21. In this case, it is possible to encourage the worker to perform the work in a more appropriate procedure.

  Further, the control device 8 may be used to turn on the lighting device 7 in accordance with the operation of the operating body 21. In this case, the position of the car 3 can be confirmed more reliably.

  Further, the control device 8 may be used to notify the information for prompting the confirmation of the position of the car 3 and to turn on the lighting device 7. In this case, not only can the operator be prompted to perform work in a more appropriate procedure, but also the position of the car 3 can be confirmed more reliably.

  Further, the stopper 23 and the like may be applied to the single-sided landing door 4. Also in this case, the position of the car 3 can be confirmed by an appropriate method before getting on the car 3.
