Abstract

PURPOSE:To prevent a surface plate from being removed by devilment by providing the first engaging piece for pressing a pin in a case side and the second engaging piece engaged with the pin and displaced in a non-engaging position relating to the pin pressed elastically deformed by artificial operation. CONSTITUTION:A surface plate 3 is pulled to a case 1 by engaging the first engaging piece 6 with a pin 4 and mounted to the case 1 by fitting the pin 4 into a fitting hole 7a. When the mounted surface plate 3 is pried opened by devilment, engagement of the first engaging piece 6 with the pin 4 is released. However, engagement of the pin 4 with the second engaging piece 7 is held, so that the surface plate 3 can not be removed only by operation of prying the surface plate 3 opened. In this way, obstruction of utilizing an elevator, generated by removing the surface plate 3 by devilment, can be decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to the structure of an elevator equipment box including a 1-position indicator, 5-hall buttons, and the like.

[Prior Art] Figs. 5 to 8 show a conventional elevator equipment box as shown in, for example, Japanese Utility Model Application No. 59-78362.

In the figure, ) is a case that is fixed to the wall (2) of the building in a buried state, with side (la), bottom (], b), and bottom (lb)
) is formed. (3)
is a top plate placed to cover the open part (1c) and has a 5 display body (
3a).

The push button (3bl) has a recess (3c) on the back edge.(4) stands up from the side wall a) and is attached to the case (
1) A pin located inside the top plate (3) with its longitudinal axis parallel to the surface of the top plate (3);
is a guide plate facing the side surface (1a) with the base (
A guide groove (5b) is formed which extends from the tip (5a) to the tip, opens at the tip edge, and fits into the pin (4). (
6) is an L-shaped engagement piece made of a linear spring; one end of the L shape is fixed to the base (5a) of the guide plate (5), and the curved part of the L crosses the length of the guide groove (5b). The base (5
A first oblique side (6a) is located near a), and a second oblique side (6b) connected to the first oblique side is formed.

The conventional elevator equipment box is constructed as described above, and when attaching the top plate (3) to the case (1), the guide plate (
A pin (4), the tip of which is inserted into the case (5), is disposed within the wide opening of the guide groove (5b). When the top plate (3) is pushed into the case from this state, the second slope (6b) of the engagement piece (6) is pressed and bent by the pin (4), and then the L-shaped curved part Pass through the pin (4)
is pressed by the first slope (6a). As a result, the top plate (3) is pulled toward the case (1) by the engagement piece (6) via the pin (4), and is attached to the case (1). In addition, when removing the attached top plate (3), pry it open through the recess (3c) as shown in Figure 6, and relatively displace the pin (4) to the outside of the first slope (6a) to guide it. The plate (5) is pulled out into the case (1).

[Problem to be solved by the invention] The conventional elevator equipment box as described above has two front plates (3)
The heads of the mounting screws are not exposed on the surface to improve the appearance. but.

Since the top plate (3) is held only by the spring force of the engagement piece (5), the top plate (3) is easily removed by mischief, which poses a problem that does not interfere with the use of the elevator.

This invention was made to solve this problem, and the object is to obtain an instrument box for a nilevator that requires release of the second engagement in order to remove the top plate.

[Means for Solving the Problems] In the elevator equipment box according to this invention, a first engaging piece presses a pin on the case side, and a pin that engages with the pin and is elastically deformed when pressed by human operation. On the other hand, a second engagement piece is provided that is displaced to a non-engagement position.

[Operation] When the top plate of the elevator equipment box configured as described above is pried open, the holding by the first engagement piece is released. However, the engagement by the second engagement piece continues, and by elastically deforming the second engagement piece, the top plate can be removed.

[Example] Figures 1 to 4 are diagrams showing an example of this invention.
The same reference numerals as in FIGS. 8 to 8 indicate corresponding parts.

(5c) is an operation hole consisting of a through hole provided in the guide plate (5), (6) is a first engagement piece similar to the engagement piece (6) in FIGS. 5 to 8, and (7) is made of elastic plate material, and one side has a top plate (3
) Fixed on the back side and facing the guide plate (5), the guide plate (5)
A second engagement piece disposed on the opposite surface (1a) of the pin (4), which is formed corresponding to the guide groove (5b) of the guide piece (5).
) and is provided with a fitting hole (7a) extending in the longitudinal direction of the guide groove (5b).

In the elevator equipment box configured as described above, the first engagement piece (6) engages with the pin (4) and the top plate (3)
is attracted to the wooce (1), and the pin (4) is fitted into the fitting hole (7a), so that the top plate (3) is attached to the case (1). When removing the first top plate (3), the following operation is performed. That is, when the top plate (3) is pried open through the recess (3c), the pin (4) moves into the guide groove (5b).
), the first engaging piece (6) is bent and the engagement with the pin (4) is released. Next, the second engagement piece (7) is pressed by a rod-shaped tool through the operation hole (5c).

As a result, the second engaging piece (7) is bent in the direction in which the tip of the pin (4) is removed from the fitting hole (7a), resulting in the state shown in FIG. 4. and.

From the state shown in FIG. 4, the guide plate (5) is pushed out from the case and the top plate (3) is removed.

Furthermore, when the attached top plate (3) is pried open by mischief, the engagement between the pin (4) and the first engagement piece (6) is released. However, the pin (4) and the second engagement piece (7)
Since the engagement of the top plate (3) is maintained, it is impossible to remove the top plate (3) by simply prying the top plate (3) open. Therefore, it is possible to reduce the number of problems caused by elevator use caused by the first top plate (3) being removed by mischief.

[Effects of the invention] As explained above, in this invention, although the engagement by the first engagement piece is released when the top plate is pried open, the engagement by the second engagement piece is continued. It is something. For this reason, it is difficult to remove the top plate when the top plate is tampered with, and there is an effect of reducing troubles in using the elevator caused by the removal of the top plate.
