Next, the procedure of the repair work to the elevator hall display device as described above will be described.
First, parts other than the box 2 are removed from the elevator hall display device before the repair as shown in FIG. 13, and the inside of the box 2 is exposed to the hall side as shown in FIGS. Thereafter, as shown in FIGS. 16 and 17, the first clasp 11 is fastened to the stud bolts 7 and 8, and the second clasp 19 is fastened to the stud bolts 15 and 16. Here, the length dimension C between the center of the hole 11a and the center of the hole 19a is measured.

  Further, as shown in FIG. 18, after the stud bolts 25 and 26 are inserted into the pair of long holes 14e, nuts 29 and 30 are screwed into the stud bolts 25 and 26, whereby the second mounting metal. 22 is connected to the first attachment 14. Here, the first and second mounting brackets are such that the length dimension between the center of the countersink 14a and the center of the countersink 22a is equal to the length dimension C between the center of the hole 11a and the center of the hole 19a. 14, 22 is slid to adjust the length. As a result, the first and second attachments 14 and 22 can be attached in the box 2.

  Further, as shown in FIG. 10, the dimension K between the center of the countersink 4a and the center of the countersink 4b of the decorative plate 4 is measured. Then, as shown in FIG. 2, the first and second attachments 14 and 22 are attached to the first and second clasps 11 and 19. The position of the slide nut 23 is set such that the dimension between the center of the screw hole 14b and the center of the slide nut 23 is equal to the dimension K between the center of the countersink 4a and the center of the countersink 4b of the decorative plate 4. . Thereby, the decorative board 4 can be attached to the first and second attachments 14 and 22.

  Next, as shown in FIG. 20, the decorative plate 4 is attached to the first and second attachments 14 and 22. Here, countersunk screws 47 and 48 are screwed into the pair of screw holes 14b. Further, a countersunk screw 49 is inserted into the countersunk hole 4 b, and the countersunk screw 49 is screwed to the slide nut 23. Further, the holding metal fitting 39 at the lower part of the decorative plate 4 is engaged with the pin 24 of the second mounting bracket 22.

  Then, after the stud bolts 31 to 36 are inserted into a plurality of holes (not shown) provided in the display base 5, nuts 50 to 55 are screwed to the stud bolts 31 to 36, thereby displaying. The vessel base 5 is fastened to the decorative plate 4.

  As shown in FIG. 21, the control line 56 coming out of the box 2 passes through the first control line through hole 14c, the second control line through hole 4c, and the third control line provided in the display base. The new hall indicator 6 is connected through the hole 5b. Then, the new hall indicator 6 is fitted into the mounting frame 5a, and the repair of the elevator to the hall display device shown in FIG. 1 is completed.

  In the elevator hall display device as described above, the first and second mounting brackets 14 and 22 are slidably connected to each other and can be expanded and contracted in the longitudinal direction of the box 2. , 22 can correspond to the length of the box 2.

  In addition, by making the same first and second attachments 14 and 22 correspond to existing boxes having different lengths, the construction period can be shortened and the repair cost can be reduced.

  Furthermore, since the lower part of the decorative board 4 is fixed to the second mounting metal 22 by the holding metal fitting 39 and the new hall indicator 6 is fitted into the attachment frame 5a, the surfaces of the decorative board 4 and the new hall indicator 6 are displayed. Thus, the design can be improved without exposing the mounting bracket such as screws.

  In the first embodiment, the first and second attachments 14 and 22 are slidable and extendable by the long hole 14e and the stud bolts 25 and 26. However, the sliding by the long hole and the insertion portion is possible. It is not limited to movement, and the attachment member only needs to expand and contract in the longitudinal direction of the box.
