Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a wiring device mounting stand used for attaching wiring devices such as switches and outlets to indoor walls and the like.

[Prior art] CryILf”d(d)j+1 Sofuhikinol+Small-1M9;↓
There is a table. To attach this type of outlet 1 to an indoor wall or the like, a wiring device mounting frame 2 as shown in FIGS. 5(a) and 5(b) has conventionally been used. The wiring device mounting frame shown in the figure is the one previously filed by the applicants of the present application (Utility Application No. 158241/1982).In other words, the conventional wiring device mounting frame 2 shown in the figure is mounted in the center. A hole 3 is drilled, and three sets of locking parts 6 and 7 for attaching an outlet are formed on the side walls 4 and 5, and when the outlet 1 is inserted into the central mounting hole 3, the locking parts 6 are , 7 are engaged with the engaging portions 8.9 of the outlet 1 for attachment. This wiring equipment mounting frame 2 is screwed to a box 112 arranged on an indoor wall, and a plate edge frame (not shown) is attached to the outer periphery of the side wall of the wiring equipment mounting frame 2 with mounting screws. A decorative plate (not shown) that can be attached to this plate edge frame covers the top surface to form an indoor outlet.

[Problems to be Solved by the Invention] However, in the conventional example as described above, in order to form an indoor outlet, the mounting frame 2. A total of three parts are required: the edge frame and the decorative plate (not shown), and four screws must be tightened to assemble them. Therefore, the number of parts is large and the installation work is complicated. It had the following drawback. Further, as shown in FIG. 5(a), in the conventional mounting frame, only the top and bottom ends contact the wall surface 111a, and the left and right ends are floating when the box 111 is in contact with the wall surface 111a.
Since it is screwed into the box, there are drawbacks such as distortion inward of the box and uneven surface of the wiring device.

The present invention has been made to solve the above-mentioned problems, and its purpose is to reduce the number of parts and facilitate installation work.
Moreover, it is an object of the present invention to provide a wiring equipment mounting base that can be constructed in a stable wiring equipment mounting state.

[Means for Solving the Problems] In order to solve the above-mentioned problems and achieve the object of the invention, the present invention provides a plate mounting frame body having a wiring device mounting portion;
It has a configuration that includes an outer plate that has a border frame portion and a decorative plate portion and is detachably attached to the plate attachment frame.

Here, as a means for attaching the external plate to the above-mentioned attachment frame, for example, engaging protrusions 15 and 26 are formed on each member, and the engagement can be carried out with one touch.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of the external plate, and FIG. 2 shows the structure of the mounting frame.

In FIG. 1, reference numeral 11 indicates an outer plate made of synthetic resin. The outer plate 11 has a peripheral portion formed as an edge frame portion 12, and this edge frame portion 12
A continuous upper surface portion is formed as a decorative plate portion 13. The edge frame portion 12 is for covering up the area around the buried portion of the box 112 in the indoor wall 111, and the decorative plate portion 13 is for covering up a mounting frame body 14, which will be described later. In this way, the external plate ll mainly forms the exterior of the indoor outlet. Furthermore, elastically deflectable engagement protrusions 15 are formed at 4 positions on the inner surface of the external play 11. A central hole 16 is formed in the center of the external plate 11 to expose the operating surface of the wiring device.

On the other hand, in FIG. 2, reference numeral 14 indicates a plate mounting frame. This plate mounting frame 14 has a wiring equipment mounting hole 17 formed in the center as a wiring equipment mounting part, and a locking part 20 for attaching an outlet to the side wall 18.19.
21 is formed, for example, as shown in FIGS. 4(a) and (b).
It is possible to attach three outlets 101 as shown in the figure. That is, the locking portions 20 and 21 have the structure shown in FIG.
As shown in C), a locking projection 22.23 is formed that projects inward, and a locking gap 24.25 is formed above the locking projection 22.23 in the drawing.
is formed. Incidentally, one of the locking portions 20 can be elastically bent outward, so that A −j l−te 7Lr+] (
gl ) L#云1-+1y JF Sok 1 To install 1, while engaging the locking protrusion 23 in the engagement hole 8,
One of the locking portions 20 is bent outward to engage the corresponding engagement hole 9 with the locking protrusion 22. In addition, in order to attach the electrical outlet 101 shown in FIG. 4(b), one of the locking portions 20 is bent outward while the engaging projection piece 102 is engaged with the locking gap 25. Engagement protrusion piece 1
03 into the locking gap 24.

Furthermore, engagement protrusions 26, which engage with the engagement protrusions 15 formed on the external plate 11, are formed at four predetermined locations on the plate attachment frame 14. FIG. 3 is an enlarged sectional view showing the shape of these engaging protrusions 26. These engaging protruding pieces 15' and 26 are external pieces)
11 to the plate mounting frame 14. According to the engagement of the engaging protruding pieces 15 and 26 that can be elastically bent to each other in this way,
This has the effect that easy and reliable attachment is possible with one touch, and there is little risk of the engaging protrusion pieces 15, 26 breaking.

Further, the plate mounting frame 14 is formed with dimensions such that the side walls 18 and 19 are in contact with the indoor wall surface 111a as shown in FIG. 2(c).

Therefore, bending and deformation during installation on indoor walls is prevented.
Wiring equipment can be installed stably.

It goes without saying that the above-mentioned dimensions may be appropriately changed in design depending on the size of the box 112 embedded in the indoor wall.

In FIG. 2, 31 is a long hole for screwing to the box 112 embedded in the interior wall 111, and 32 is a locking hole for attaching to the panel wall.

The wiring equipment mount having the above-described configuration can form an indoor outlet in the following manner. The work described below is an example of work performed as part of the house construction process.

First, the plate attachment frame 14 is attached and fixed to an indoor wall, etc.
Wiring devices such as an outlet t and a lot are attached to the plate attachment frame 14. At this time, in order to prevent deformation of the retaining protruding piece 26, it is desirable that the base of the retaining protruding piece 26φ is in contact with the indoor wall surface 111a.Such work is generally done during electrical work before pasting wallpaper. It is carried out on the occasion of

Next, after finishing the interior work such as gluing wallpaper, the external plate 11 is attached to the plate attachment frame 14. This work can be easily done in one go. In this way, the edges of the wallpaper are also covered by the external play) 11, making it possible to form an indoor outlet without spoiling the aesthetics of the room.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the gist of the invention. As a means for attaching to the latch, it is also possible to use a method generally used as this type of attaching means, such as engagement between a retaining protrusion and a latch portion.

[Effects of the Invention] As is clear from the above description, according to the present invention, since the outer plate is formed by integrating the edge frame and the decorative plate, the number of parts is reduced.

It is easy to install and has an aesthetic effect of having a smooth and clean appearance.

Furthermore, if the dimensions of the plate mounting frame are set so that the side walls of the plate mounting frame come into contact with the indoor wall surface, it is possible to prevent the plate mounting frame from bending and deforming, so the wiring equipment can be mounted in a stable state. Can be done.
