  In the hall door device according to the present embodiment, the maintenance staff is in the car 14, and can perform maintenance and inspection work in the same procedure at any floor hall as follows.

  First, in FIG. 1A, the car 14 is stopped at an elevator hall on an arbitrary floor. When the landing door device 20 is inspected, the landing height H is set so that the maintenance staff in the car 14 can easily remove the header cover 24.

  When the car door panel 16 is opened after stopping the car 14 in such a position, as shown in FIG. 1B, the upper half of the landing door panel 18 and the header cover 24A can be seen in front of the doorway. ing. Header covers 24B and 24C on the left and right sides of the header cover 24A are hidden behind the return panels 35A and 35B.

  Next, the header covers 24A, 24B, and 24C are removed. In that case, first, the central header cover 24A is removed. In the case of this header cover 24 </ b> A, if the maintenance person loosens the screw 48, it can be taken out while supporting it.

  Thus, when the header cover 24A is taken out, it becomes as shown in FIG. The header covers 24B and 24C on both sides can be moved in the direction of the arrow if the screws 49 are loosened. The order of taking out the header covers 24B, 24C may be either.

  When the header cover 24C is taken out, if the header cover 24C is moved to the left, the sliding roller 44 rolls smoothly along the guide edge 21c of the header case 21, so that the maintenance staff can easily place the header bar 24C in the center. It can be moved to the position. Then, it can be taken out by pulling forward while supporting the header cover 24C. The same applies to the removal of the other header cover 24B. If the header case 21 can be inspected without taking it out, the header covers 24B and 24C may be moved and looked into.

  Thus, when the header covers 24A, 24B, and 24C are removed, the interior of the header case 21 is exposed, so that maintenance personnel in the car visually inspect each part of the header case 21.

  The both end sides of the header case 21 may be difficult to see even when viewed from the inside of the car. In this case, in FIG. 1, since the return panels 35A and 35B are of an openable type, if the return panels 35A and 35B are opened, the inspection can be performed through the inspection window 36.

  After the inspection is completed, the header covers 24B and 24C are attached to the header case 21, and then the header cover 24A is attached last.

  As described above, according to the present embodiment, the header covers 24A, 24B, and 24C can be removed from the cage in an easy-to-work posture, and the inside of the header case 21 can be visually inspected. In this way, maintenance and inspection of landing door devices on all floors can be carried out from within the car, and as in the past, a scaffold is built in the pit on the lowest floor, and on the other than the lowest floor, Since work is not performed at high places, it is possible to proceed with maintenance and inspection work safely and efficiently.
