10 is a sectional view showing a state in which the cover is pulled up, FIG. 3 is a sectional view showing a state in which the cover of an elevator equipment box according to an embodiment of the present invention is pulled up, and FIG. It is equivalent.

Incidentally, since the front view showing the elevator equipment box of one embodiment of the present invention is the same as FIG. 4, the drawing is omitted. Further, in the drawings, the same reference numerals and the same symbols indicate the same or corresponding parts, so a redundant explanation will be omitted here.

In the figure, (18) is an elastic body made of a spring wire protruding from the back edge of the cover (6), and one end is connected to the cover (6).
and the guide piece (10), and is attached together with the guide piece (10) by a nut (11), and the other end is bent into a substantially doglegged shape along the inner side surface of the case body (2). Furthermore, its tip is extended and curved into a substantially U-shape. The upper inclined part (12a) of the curving shape serves as a pressing part for the pin (9), and the approximately U-shaped curved part serves as a receiving part for the pin (9). That is, in the configuration of this embodiment, a substantially U-shaped curved portion (18c) is attached to the tip of the elastic body (12) of the conventional example, and the string (13) for preventing the cover (6) from falling off is eliminated. It is something. (19) is a driver. The configuration of this embodiment other than those described above is the same as that of the conventional one shown in FIGS. 4 to 6, so a description thereof will be omitted.

Next, the operation of the elevator equipment box of this embodiment configured as described above will be explained.

When installing the cover (6), first attach the guide piece (10).
The pin (9) is aligned with the groove (10b) of the elastic body (18), and the pin (9) is brought into contact with the outside of the curved portion (18c) of the elastic body (18). Next, press the cover (6) toward the case body (2). As the cover (6) is pressed toward the case body (2), the pin (9) pushes the outside of the curved portion (18c) of the elastic body (18) to the left in FIG. (
18) Move inside. From this, like the conventional example,
The groove (10b) of the guide piece (10) moves while being guided by the pin (9). At the same time, the lower inclined part (18b) of the elastic body (18) is pushed by the pin (9) to the left in FIG.
, the upper slope (18a) engages with the pin (9). At this time, this pin (9) is pulled in the direction of the cover (6) by the elastic force of the elastic body (18), so that the cover (6) is attached to the surface of the wall (1) or the case body (2). Close contact with the opening.

On the other hand, when removing the cover (6), simply pull the cover (6) as it is, and the cover (6) will be removed from the groove (10) of the guide piece (10).

The elastic body (18) is pushed to the left by the pin (9), and when it passes through the approximately doglegged bending point, it is immediately hooked onto the curved portion (18c), as shown in FIG. Here, use a screwdriver (19) etc. to attach the elastic body (18) to the case body (2).
) or to the left in FIG. 2, the elastic body (18) comes off the pin (9) and the cover (6) separates from the case body (2).

In use, even if the pin (9) comes off from the upper inclined part (18a) of the elastic body (18) and the cover (6) floats due to contact with a passenger or loosening of the elastic body (18),
Since the pin (9) is hooked to the curved portion (18c) of the elastic body (18), the cover (6) will not move any further and will not separate from the case body (2).

In this way, the elevator equipment box of this embodiment has a pin (9) that protrudes from the inner side wall of the case body (2) and a pin (9) that protrudes from the back surface of the cover (6) that covers the opening of the case body. a guide piece (10) that fits with the pin (9) to regulate the position of the cover (6); and a guide piece (10) that protrudes from the back surface of the cover (6) and engages with the pin (9). a curved portion (18c) that holds the cover (6) on the case body (2) and receives the pin (9) to prevent it from falling off.
It is composed of an elastic body (18) having a.

Therefore, according to this embodiment, when removing the cover (6) during installation or inspection of the stored equipment, the cover (6) is removed until the pin (9) is hooked to the receiving part (18c) of the elastic body (18). The cover (6) can be removed simply by pulling out the cover (6) and pushing the elastic body (18) hooked to the pin (9) from the outside with a screwdriver (19), making the work easier. Become. Also, in the analogy, the pin (9) is an elastic body (18)
Even if the elastic body (18) comes off the upper slope part (18a) of the
Since the cover (6) is hooked to the curved portion (18c) of the cover (6), it is possible to prevent the cover (6) from falling off.

Furthermore, in this embodiment, the number of parts can be reduced because the string (13) for preventing falling off is not used as in the conventional case.
The cost is reduced, and since the cover (6) is not suspended, the wall (1) is not damaged by its shaking.

Incidentally, although the present embodiment has been explained using a display panel in a hall as an example, it is clear that the present invention can be applied to other hall buttons, in-car operation panels, etc.

In addition, in the above embodiment, the cover (6) and the guide piece (1
0) is integrally molded from a plastic material, and the elastic body (18) is attached by insert molding the end portion, thereby reducing the assembly cost and also making it possible to eliminate the nut (11).

[Effects of the Invention] As described above, the elevator equipment box of the present invention includes a pin protruding from the inner side wall of the case body, and a pin provided on the back surface of the cover covering the opening of the case body, which is fitted into the pin. a guide piece that guides the position of the cover; and a guide piece that is disposed on the back side of the cover and engages with the pin to hold the cover to the case body and to hold the cover and the case body together. It is composed of an elastic body having a receiving part that engages with the pin when it is undone to prevent it from falling off, so when removing the cover during installation or inspecting the stored equipment, the pin will not fit into the elastic body. The cover can be removed simply by pulling the cover out to the position where it is latched to the receiving part and pushing the elastic body latched to the pin from the outside with a screwdriver or the like, making the work easier. Further, even if the pin comes off from the suppressing part of the elastic body, it is hooked to the receiving part of the elastic body, so that the cover can be prevented from falling off. Furthermore, since no strings are used to prevent the cover from falling off, the number of parts can be reduced, reducing costs, and since the cover does not need to be hung, there is no chance of damaging the wall.
