  Hereinafter, an embodiment according to an elevator apparatus of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic configuration diagram of an elevator apparatus according to the present invention. The elevator apparatus of the present invention is configured such that a car 1 and a counterweight 2 are raised and lowered along a guide rail (not shown). The car 1 and the counterweight 2 are suspended in a hanger manner by the main rope 4 via the hoisting machine 3 and are driven up and down in the hoistway 5.

  FIG. 2 shows a schematic configuration diagram in the car 1. The car 1 includes a side wall plate 6a, a front wall plate 6b, a rear wall plate (not shown), and a door 7 for passengers to enter and exit. The front wall plate 6b has a car as shown in the figure. An inner operation panel 8 is installed.

  FIG. 3 is a cross-sectional view taken along the line AA of the front wall plate 6b on which the operation panel 8 shown in FIG. 2 is installed. The front wall plate 6 b is configured to have a space 9 for accommodating the operation panel 8.

  FIG. 4 is a front perspective view of the in-car operation panel 8 of the present invention. The in-car operation panel 8 includes an upper panel 10 having a display panel for displaying the current floor, an intermediate panel 11 having operation buttons 14 for registering destination floors and opening / closing doors, and a box that cannot be operated by normal operation. A switch box 12 having an operation switch housed therein, a lower panel 13 composed of a design panel for improving the design of the operation panel, and a pair of L-shaped cross sections arranged at the left and right ends of the above 10-13 10 to 13 are integrated by a reinforcing plate 15 having a shape. The reinforcing plate 15 has an L-shaped cross-sectional shape that is short in the horizontal direction shown in FIG. 4 in order to secure an arrangement space for internal devices such as the operation buttons 14 and long in the depth direction in order to secure strength against torsion. By integrating 10 to 13 with the reinforcing plate 15, the in-car operation panel 8 is fixed only by the means for fixing the reinforcing plate 15 and the front wall plate 6b, and it is necessary to fix 10 to 13 individually. Therefore, it is possible to reduce the number of parts and improve workability during installation work.

  FIG. 5 shows a cross-sectional view taken along the line BB of the in-car operation panel 8 shown in FIG. The in-car operation panel 8 mounts operation panel internal devices such as the operation buttons 14, but the internal devices can be fixed by press-fitting a plurality of press stud bolts 16 into the reinforcing plate 15. FIG. 5 shows a method of fixing the button fixing plate 17 with the press-type stud bolt 16 as an example of a method of fixing the operation button 14. In the in-car operation panel 8 of the present invention, the reinforcing plate 15 has a role of integrating 10 to 13, a role of fixing the in-car operation panel 8 to the front wall plate 6b, and a role of fixing the devices inside the operation panel. Since it can be performed at the same time, the number of parts can be reduced, so that the assembly workability can be improved.

  6 is an enlarged view of a press-type stud bolt 16 press-fitting method, FIG. 7 is a compression force generated by the movement of the reinforcing plate during press-fitting of the press-type stud bolt 16, and FIG. 8 is a press-fit of the press type stud bolt 16. 8 shows the distortion of the reinforcing plate, and the upper diagram in FIG. 8 shows the state before press-fitting stud-type bolts and the lower diagram shows the state after press-fitting stud-type bolts. As shown in FIG. 6, the press stud bolt 16 has a prepared hole 18 slightly larger than the outer diameter of the bolt in the reinforcing plate 15, and the press stud bolt is inserted into the pilot hole 18. The part is fixed by being embedded in the reinforcing plate 15 by a press machine. By embedding the head of the press-type stud bolt 16, the plate material moves, and the reinforcing plate 15 has a compressive force 19 in the radial direction of the press-type stud bolt as shown in FIG. To do.

  In the reinforcing plate 15 having an L-shaped cross-sectional shape, the deformation amount is small on the X side where bending is performed and the deformation amount is large on the Y side where bending is not performed as shown in FIG. Therefore, the reinforcing plate 15 is warped in a state where the L-shaped cross-sectional surface in the depth direction is warped. In the in-car operation panel of the present invention, a plurality of press-type stud bolts 16 are press-fitted into the reinforcing plate 15, so that a large warp occurs in the reinforcing plate 15 due to accumulated distortion, and the press-type stud bolt 16 is press-fitted. After that, since the work of correcting the distortion of the reinforcing plate 15 is required, there is a concern that the production workability is deteriorated.

  9 to 11 show an embodiment of the reinforcing plate of the present invention. The upper diagram shows the state before press-fitting the stud stud bolt, and the lower diagram shows the state after press-fitting the stud stud bolt. Show.

  In FIG. 9, the reinforcing plate 15 has a structure in which a hole 20 a for absorbing the movement of the plate material is provided separately from the prepared stud 18 for press-fitting the stud stud bolt 16. That is, the hole 20a is a compression force absorbing hole that absorbs the compression force 19 caused by the movement of the meat generated when the press-type stud bolt 16 is press-fitted by deforming the hole. By absorbing the compression force 19 caused by the movement of the meat generated when the press-type stud bolt 16 is press-fitted, the hole 20a is deformed like Z, but the influence on the shape of the reinforcing plate 15 can be reduced. Thereby, since the distortion correction work after press-fitting the press-type stud bolt 16 is not required, the workability of manufacturing the reinforcing plate 15 can be maintained. Further, in this embodiment, since the holes 20a are added in the plate width direction of the reinforcing plate 15, the influence on the minimum press-fitting interval of the press type stud bolt 16 can be suppressed.

  In FIG. 10, the reinforcing plate 15 has a structure in which two holes 20b are provided in the width direction of the reinforcing plate. That is, the hole 20b is a compression force absorbing hole that absorbs the compression force 19 due to the movement of the meat generated when the press-type stud bolt 16 is press-fitted by deforming the hole. Since the compression force 19 caused by the movement of the meat generated when the press-type stud bolt 16 is press-fitted can be absorbed by the two holes 20b, the distortion reduction effect of the reinforcing plate 15 can be enhanced. This embodiment is effective when the plate width of the reinforcing plate 15 is large, and since the holes 20b are added in the plate width direction of the reinforcing plate 15 as in the case of FIG. The influence on the press-fitting interval can be suppressed.

  In FIG. 11, the reinforcing plate 15 has a structure in which two holes 20 c are provided in the longitudinal direction of the reinforcing plate. That is, the hole 20c is a compression force absorbing hole that absorbs the compression force 19 due to the movement of the meat generated when the press-type stud bolt 16 is press-fitted by deforming the hole. Similarly to the case of FIG. 10, since the compressive force 19 due to the movement of the plate material can be absorbed by the two holes 20 c, the distortion reducing effect of the reinforcing plate 15 can be enhanced. In this embodiment, since the hole 20c is added in the longitudinal direction of the reinforcing plate 15, the minimum press-fitting interval of the press-type stud bolts 16 is increased, but it is effective when the plate width of the reinforcing plate 15 is small.

  If the reinforcing plate 15 is distorted by the press-type stud bolt, it may not be possible to store it in the space 9 for storing the operation panel 8 of the front wall plate 6b constituting the car, or the panels 10, 11, 13 In some cases, the box 12 cannot be attached to the reinforcing plate 15. Thus, when distortion of the reinforcing plate 15 occurs, reworking for correcting the distortion is required. In particular, the reinforcing plate 15 is provided with the panels 10, 11, 13 and the box 12, and the press-type stud bolt 16 is provided on the short side surface of the L-shaped cross section. Even if the distortion due to the operation panel 8 is slight, if a plurality of press-type stud bolts 16 are provided on the reinforcing plate 15 having almost the same length as the longitudinal direction of the operation panel 8, a very large distortion is caused and the L-shaped cross-section Since the other surface is long in the depth direction in order to ensure strength against torsion, it is very difficult to correct the distortion. However, by providing the compression force absorbing hole, this work can be omitted and the assembly efficiency can be greatly increased.

  In the present embodiment, the compression force absorbing holes 20a to 20c are rectangular, and the long sides thereof are provided so as to face the prepared hole 18 for press-fitting a stud stud bolt. In such a configuration, the holes 20a to 20c are likely to be deformed by the compressive force 19 caused by the movement of meat generated when the press-type stud bolt 16 is press-fitted into the prepared hole 18. That is, the compression force 19 can be absorbed well, and a space for providing the compression force absorption holes 20a to 20c can be reduced as compared with other shapes. However, even if other shapes have different effects, the distortion of the reinforcing plate 15 can be reduced.

  Thus, a plurality of press-type stud bolts 16 are provided on the short side surface of the L-shaped cross-section reinforcing plate 15 to attach the panels 10, 11, 13 and the box 12, and the other surface of the L-shaped cross-section is in the depth direction. In the elevator car operation panel and elevator device, which has a structure with a very long length in the longitudinal direction to ensure the strength against torsion, the press die without the need to readjust the distortion Providing stud bolts can improve production work efficiency and is very effective. And since the hole for press-type stud bolt press-fit and the hole provided separately from it can also be provided simultaneously by press work etc., it is also possible to prevent the drilling operation from newly increasing.

  As explained above, the reinforcing plate has a role to integrate and reinforce each part of the operation panel such as the upper panel, intermediate panel, switch box, lower panel, etc. The press-type stud bolt that has been press-fitted can be used to simultaneously fix the operation panel and other equipment inside the operation panel, and the number of parts can be reduced, so that the assembly workability can be improved. Further, when the operation panel is installed in the elevator car, it can be fixed to the operation panel box using the reinforcing plate. And since the added hole absorbs the distortion caused by the movement of the plate material during press-type stud bolt press-fitting, there is no need to correct the distortion of the reinforcing plate after press-type stud bolt press-fit. The improvement of workability of board production can be expected.
