BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator digital indicator mounting device used when replacing an existing analog indicator with a digital indicator.

[0002]

2. Description of the Related Art Conventionally, many analog indicators have been installed on elevator halls. However, in recent years, various thin digital indicators having excellent design have been developed. The renewal of replacing the indicator has been started.

FIGS. 7A and 7B are views for explaining a schematic configuration of an analog indicator. FIG. 7A is a front view, and FIG. 7B is a partial sectional side view. As shown in FIG. 7, the analog indicator includes a display unit 2 that displays the floor position of the car to be operated in an analog manner, a storage box 5 provided in a recess of the landing wall 1, and a storage box 5. The stored electrical components 3 and the wiring cords 4, the screws 6 for fastening the upper part of the display unit 2 to the screw fixing parts 5a of the storage box 5, and the lower parts of the display unit 2 for screw fixing parts 5b of the storage box 5 And a screw 7 which is fastened and fixed to the shaft. The display unit 2 is attached at a position that covers the storage box 5, and a display area 2a that indicates the floor position of the car is provided on the front surface of the display unit 2.

FIG. 6 is an explanatory view of the prior art showing a state in which the existing analog indicator is replaced with a digital indicator 10. FIG. 6 (a) is a front view and FIG. 6 (b).
Is a partial cross-sectional side view, FIG. 4C is a top view, and FIG. 4D is a bottom view. As shown in FIG. 6, the new digital indicator 10 is mounted on the front surface of a frame 11 attached to the storage box 5 for the analog indicator. That is, first, the fastening of the screws 6 and 7 of the analog indicator is released, the display unit 2, the electric components 3, the wiring cord 4 and the like are removed, and then the frame 11 is fastened to the screw fixing units 5 a and 5 b of the storage box 5. Fix it. At this time, the wiring code 14 of the newly installed digital indicator 10 is inserted into the storage box 5.
Keep it inside. In a state where the digital indicator 10 is put on the frame 11, the upper ends of both the digital indicators 10 and 11 are connected to each other with a screw 12, and both the digital indicators 10 and 11 are connected.
The digital indicators 10 are fastened and fixed to the frame 11 by connecting the lower ends of the 11 with screws 13. By doing so, there is no need to remove the storage box 5 for the analog indicator, so that the replacement work for the digital indicator 10 can be performed relatively easily.

[0005]

In the prior art as shown in FIG. 6, the heads of the screws 12, 13 are exposed at the upper end and the lower end of the newly installed digital indicator 10, but the design is improved. From the viewpoint, a mounting structure in which such screws are not exposed is desired. In the related art, the digital indicator 10 is attached to the frame 11 in addition to the screws 6 and 7 for fastening and fixing the frame 11 to the storage box 5.
Since the screws 12 and 13 for fastening and fixing the screws are required, the work of fastening these screws is complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide an elevator which can easily replace an existing analog indicator with a new digital indicator and is suitable for improving design. It is to provide a digital indicator mounting device.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a storage box provided in a recess in a landing wall, in which electric parts and wiring cords are stored.
An existing analog indicator, which is arranged at a position covering the storage box and fixed to the storage box with a screw, displays an analog display of the floor position of the operated car, a digital indicator In the elevator digital indicator mounting device used when replacing the digital indicator, the digital indicator having a frame disposed on the back side of the digital indicator and fixed to the screw fixing portion of the storage box, and a locking hook Hook engaging means capable of connecting the indicator and the frame body, and spring engaging means having a pressing spring and capable of connecting the digital indicator and the frame body are provided.

When the digital indicator mounting device having such a configuration is used, when replacing an existing analog indicator with a new digital indicator, the digital indicator is mounted on a frame fastened and fixed to a screw fixing portion of a storage box of the analog indicator. In this state, the upper and lower portions of the frame and the digital indicator may be connected by hook engaging means and spring engaging means. At this time, the flexibility of the locking hook and the elasticity of the pressing spring are used. The digital indicator can snap into the frame. Therefore, the mounting work of the digital indicator can be easily performed, and the design is improved because the screws are not exposed to the outside.
