Abstract

PURPOSE:To prevent unnecessary contact with a lever and improve safety by providing a switch main body having an operation lever at the outside, with the tip of this operation lever protruded at the recessed position lower than the wall surface. CONSTITUTION:A switch device is fitted at the recessed position on the surface of a concrete panel 33 according to the shape of a fitting frame plate 37. The protruded height of the operation lever 43 of a switch main body 40 is set to the same or lower position than the concrete surface 33A, for example. Such an accident that the operation lever 43 is unnecessarily operated or the switch is broken can be thereby prevented even if baggages are moved in face contact with the concrete surface 33A.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) This invention relates to a wall switch device installed on a wall of a building or the like.

(Prior Art) A switch device placed on a wall of a building has conventionally been attached by a method as shown in FIG.

11 is a floor for forming concrete panels;
An electrical box 12 is placed on this upper surface with its opening facing down. The electrical box 12 has concrete 13
A conduit 14 disposed in is connected. concrete 1
3 is poured and hardened, the floor 11 is removed and the floor 11 is removed.
) will be in the usage state as shown below. In order to dispose the switch body 20 in the electrical box 12, the frame plate 17 is attached using the protruding pieces 15, 16 so as to close the box opening. Then, install the frame plate 1
A switch main body 2° is disposed in the central penetrating portion of the switch 7, and the switch main body 20 is fixed to the frame plate 17 using the flange 21 of the switch main body 20. Also, at this time, the switch body 20
A decorative board 22 surrounding the periphery is also attached. In addition, 24 is a top coat painted on the surface of the concrete 13.

(Problems to be Solved by the Invention) According to the wall switch device described above, the operation lever 23 of the switch protrudes from the wall surface. For this,
For example, if this switch device is located in a location such as a warehouse where transportation vehicles pass through, the switch may be damaged by contact. The same thing can be said about the places where luggage is taken in and taken out. Furthermore, damage may occur not only in warehouses, but also in general buildings, homes, etc., and accidents such as power being turned off or turned off due to unnecessary contact may occur.

Therefore, an object of the present invention is to provide a wall switch device in which the operating lever of the switch is located in a recessed area from the wall surface, thereby preventing unnecessary contact with the lever and improving safety. .

[Structure of the Invention] (Means for Solving the Problems) The present invention provides that the main body is installed with the opening facing the surface of the wall, and the main body is buried inside the wall, and the opening faces the surface of the wall. The surface includes an electrical box set in a recessed position relative to the surface of the wall, and is arranged so as to close an opening in the recessed position of the electrical box, and is provided on the inner edge of the opening by screw means. The mounting piece, which is attached to a protruding piece with a peripheral edge rising from the recessed position to the surface of the wall, is attached to the frame plate, and the attachment piece is attached to the frame plate and is attached to the electrical box. The switch body has a wire connection terminal on the inside and an operating lever on the outside, and the tip of the operating lever projects at least in a recessed position lower than the surface of the wall.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which an electrical box 32 is buried in a concrete panel 33 with its opening facing the wall surface of the panel. In this case, the opening of the electrical box 32 is recessed below the wall surface of the concrete panel 33. Electrical box 3
A conduit 34 is connected to the hole in the side wall of 2, and this conduit 3
An electric wire 50 can be introduced into the box through 4.

A frame plate 37 is attached to the opening of the electrical box 32 so as to close the opening. In this attachment, the frame plate 37 is attached to protruding pieces 35 and 36 formed to protrude inside the opening of the electrical box 32 using screws or the like. Furthermore, during installation, the peripheral edge of the frame plate 37 is attached to the surface 3 of the concrete panel 33.
3A and the opening surface of the electrical box 32. The switch body 40 is disposed passing through the frame plate 37, and the flange 41 is attached to the frame plate 41 with screws or the like. In this case, the decorative plate 4 covering the periphery of the switch body 20
4 can also be installed.

As mentioned above, the switch device of the present invention is mounted on the frame plate 3.
Due to the shape of 7, it is installed in a recessed position from the surface of the concrete panel 33. The protruding height of the operating lever 43 of the switch body 40 is regulated so as to be, for example, at the same level as the concrete surface 33A or at a position recessed from this.

Therefore, even if the cargo moves so as to come into surface contact with the concrete surface, there will be no accident such as unnecessary operation of the -43 or damage to the switch. Although the above embodiment describes the case where the electrical box 32 is buried in the concrete panel 33, the present invention is not limited to this, and can be similarly applied to a normal board wall.

Furthermore, a manufacturing example of the wall switch device of the present invention will be explained with reference to FIG. That is, as shown in FIG. 2(a), the electrical box 32 and the mounting frame board 37 are placed face down on the floor 31. In this case, the vinyl sheet 60 is attached to the outer surface of the frame board 37, and the concrete 3
3, the saucer-like attachment is designed to prevent concrete milk from entering the internal space of the frame plate 37. When the concrete panel is used after the concrete 33 has hardened, the vinyl sheet 60 is attached to close the central opening of the frame board 37, as shown in FIG. Therefore, it is possible to prevent artifacts from entering the electrical box 32 when the panel is moved. Further, although the outer surface of the concrete panel is sometimes sprayed with paint or coated with a top coat of the wall, it is possible to prevent unnecessary substances from getting into the electrical box 32 during this work. Note that when attaching the switch body 40 to the frame plate 37, the vinyl sheet 60 can be easily removed. In the above embodiment, the frame plate 37 is mounted as shown in FIG. 3(a).
As shown in FIG. 3, the peripheral edge is in an upright shape, but the frame plate 37A may be attached in such a manner that the flange 37a further extends to the peripheral edge, as shown in FIG. 3(b).

[Effects of the Invention] As explained above, the present invention provides a switch for use on a wall surface in which the operating lever of the switch is located in a recessed area from the surface of the wall, preventing unnecessary contact with the lever and improving safety. A switch device can be provided.
