Three sets of L holes 12 are drilled. The other side piece 1 of the mounting frame 1
1 is provided with a visible locking side piece 13, which is arranged in parallel on the outside of the side piece 11 and located on the back side of the side piece 11, 2 at both ends and in the middle
m points are connected to the side pieces 11 of the mounting frame 1 by bridging pieces 14.

From the locking side pieces 13 between the bridge pieces 14, white letter-shaped locking claws 15 are respectively protruded from the front side. The release piece 15a at the center of the locking pawl 15 faces the back side of the outer surface of the side piece 11. Also, the stepped portion 15b1 of WJllIII of the release piece 15a. is located behind the back surface of the side piece 11, and the step portion 15b and the side piece 11 form a locking hole 16 that faces the locking hole 12.

The wiring device 8 such as a switch attached to the mounting frame 1 is connected to the fifth
As shown in the figure, the casing includes a body 8a and a cover 8b.
The body 8a and the cover 8b are connected by two metal assembly frames 17. And assembly frame 1
7 has a pair of locking pieces 18 projecting laterally, and by inserting and locking the locking pieces 18 into the pair of locking holes 12 and 16 of the mounting frame 1, the wiring device 8 can be installed. It is detachably attached to frame 1. At this time, the wiring device 8 can be easily attached and detached due to the deflection of the locking claw 15 of the locking side piece 13. In another arrangement #i device 8' shown in FIG. 5, a locking piece 18 is integrally provided from the casing,
The connecting piece 18 allows the wiring device 8 to be attached to the mounting frame 1 in the same manner as the wiring device 8 described above.

After attaching the wiring device J%8 to the mounting frame 1, insert the screw through the long hole 5 of the mounting frame 1. The L opening 19 is screwed onto the mounting piece 4 to fix the mounting frame 1 to the embedded box 3. and,
The plate frame 6 is attached to the mounting frame 1, the screws 7 are hinged to the screw holes 9 of the mounting frame 1, and the plate frame 6 is attached. Then, a decorative plate 26 is attached to the front surface of this plate frame 6 as shown in FIG. The front surface of the plate frame 6 is recessed one step toward the rear side so that the decorative plate 26 can be attached flush to the front surface of the plate frame 6.

In such a conventional example, as described above, the wiring device i4:
The plate frame 6 was attached to the attachment frame 1 to which the decorative plate 26 was attached. Therefore, misalignment between the wiring fixture 8 attached to the mounting frame 1, the plate frame 6, and the decorative plate 26 may occur. In addition, the wiring device i%8 may be installed using a metal installation frame other than the synthetic resin installation frame 1 described above, but in this case, the wiring device 8 is caulked to the metal installation frame. Due to the mounting, the mounting position of #I weapon 8 on the metal mounting frame itself also varies, and the above positional deviation further increases Wt
Become a strawberry. Therefore, as shown in FIG. 6, a gap X is provided between the plate frame 6 and the decorative plate 2G, and this gap X absorbs the positional shift of the wiring device 8. However, when there is a gap X like this, there is a problem that the aesthetic appearance is impaired.

In addition, when removing the wiring fixture 8 attached to the conventional mounting frame 1, insert the driver 51 between the outer surface of the side piece 11 and the release piece 15m of the locking claw 15, and 13 to the outside, and the locking piece 18 of the wiring device 8 was removed from the locking hole 16 to remove it. However, the conventional mounting frame 1
In this case, the release piece 15m abuts along the tapered surface 51a of the driver 51, causing the locking side piece 13 to fall inward as shown in FIG. 8, making it difficult to remove the wiring device 8. Moreover, in this case, there is a risk that too much force will be applied to the driver 51 and the mounting frame 1 will be damaged.

Furthermore, when drilling holes in the construction surface 19 such as plasterboard,
The four corners of the square hole correspond to the shaded part A in Figure 9 of the locking side piece 13 of the mounting frame 1, which may cause problems when storing the drill. However, it is necessary to finish the four corners of the embedded hole into corners by post-processing, or to improve the accuracy of the drilling dimensions, which poses a problem in that the drilling process takes time.

1. Problems to be Solved by the Invention] The specified invention has been provided in view of the above-mentioned problems, and includes forming a plate frame in which a conventional mounting frame and a plate frame are integrated, and a plate frame that is attached to the plate frame. The circumference of the decorative plate
The object of the present invention is to provide a plate frame for a wiring device that does not have a gap in the k section.

In addition, the first related invention aims to provide a plate frame for a wiring device that facilitates the removal of the three wiring members, and the second related invention aims to provide a plate frame for a wiring device that makes it easy to remove the wiring. The purpose of this is to provide a single play frame for wiring devices that does not require any wiring equipment.

Means for Solving the 1WK Problem J In order to achieve the above object, the specified invention has an opening formed in the center through which the front side of the wiring device is inserted, and one side piece protruding from the wiring device. A locking hole is drilled into which the locking piece is inserted and locked, and the other side piece is formed by two inner and outer pieces that run by hand, and the two ends in the longitudinal direction are disposed between these inner and outer pieces. The flexible locking side piece connected to the inner and outer pieces and the inner piece form a locking hole into which the other locking piece protruding from the wiring device is inserted and locked, and the decorative plate The center portion of the front surface is recessed one step toward the rear side so that the storage recess is flush with the front surface, and the shape of the inner peripheral edge of the storage recess is approximately the same as the outer shape of the decorative plate.

Further, in the first related invention, in the configuration of the above-mentioned specific invention, the locking side piece is arranged in parallel with the inner piece so that the front edge of the locking side piece faces the back side of the outer surface of the inner piece. In the second related invention, the rear corner of the locking side piece is chamfered.

(Function) In the specified invention, as mentioned above, by integrating the conventional mounting frame and the plate frame, the positional deviation of the #l appliance is minimized, and the decorative plate is mounted flush on the front surface. The central part of the storage recess is moved one step toward the back side, and the shape of the inner peripheral edge of the storage recess is made substantially the same as the outer shape of the decorative plate, so that no gap is formed at the peripheral edge of the decorative plate.

In addition, in the first related invention, the wiring device is installed by arranging the locking side piece in parallel with the inner piece so that the front edge of the locking side piece faces the back side of the outer surface of the inner piece. When removing, the front edge of the locking side piece will come into contact with the taper of the driver inserted between the inner piece and the locking side piece, preventing the locking side piece from falling inward. This makes it possible to easily remove the wiring equipment.

Furthermore, in the second related invention, by chamfering the corners on the back side of the locking side piece, the mounting frame can be attached to the embedding hole even if precision is required for drilling the embedding hole. This is what I did.

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

This embodiment is a combination of a conventional general insulating material mounting frame and a plate frame made of insulating material, and parts having the same functions as the conventional ones are given the same numbers. .

In Fig. 1, a rectangular plate frame 21 is formed by integrating each member with an insulating material, and three standardized wiring devices each having the size of one module are attached to the center of the plate frame 21. A possible opening 2 is provided. The upper and lower parts of the r140 part 2 are provided with elongated holes 5 for attaching the plate frame 21 to the embedded box.

Three pairs of locking holes 12 are formed in one side piece 22 of the plate frame 21, similar to one side piece of a conventional mounting frame. In addition, the other side piece 23 has two inner pieces 23 that are hand-hammered.
a and an outer piece 23b, and these inner and outer pieces 23a,
A flexible locking side piece 24 is provided between the locking side piece 23&, and the locking side piece 24 and the inner piece 23m form a locking hole substantially similar to the locking hole on the other side of the conventional mounting frame. A stop hole 16 is formed.

On the back side of the locking hole 16 of the locking side piece 24, as shown in FIG.
As shown in FIG. 2, an id portion 41 is formed. This side part 41 is formed on the tapered surface 43 formed on the inner surface of the back side of the locking hole 16 of the locking side piece 24, and on the inside of the pair of locking holes 16 that hold one wiring device 8. The locking piece 18 of the wiring device 8 inserted from the back side along the back side portion of the rib 42 and the tapered surface 43 is inserted into the locking hole 16. I'm here to guide you. Note that the front side portion of the rib 42 functions to position the locking piece 18 inserted into the locking hole 16.

The locking side piece 24 of this embodiment is not provided with the conventional white letter type locking pawl, but is formed into a rectangular flat plate, and the front edge of this locking side piece 24 is connected to the inner side. 23a facing the back side of the outer surface, and the edge of the front side is connected to the locking hole 16.
as close as possible. In other words, if the front edge of the locking side piece 24 is brought as close as possible to the locking hole 16, the locking side piece 24 will not fall inward along the tapered surface 51a of the driver 51, and The wiring fixture 8 can be easily removed even with a small force, and the risk of damaging the plate frame 21 is reduced. Further, the corner portion on the back side of this locking side piece 24 is obliquely cut out and chamfered as shown in FIG. 1(c). In other words, this chamfering prevents the locking side piece 24 of the chamfered portion from coming into contact with the corner of the embedding hole drilled to attach the wiring device 8 to the construction surface 19.

This improves the ease with which the plate frame 21 can be stored in the embedded hole, and also eliminates the need for hole processing such as finishing the corners of the embedded hole into corners, reducing the drilling time.
Improves workability.

It is. By the way, the connecting portions of the locking side piece 24 to the plate frame 21 at both ends are made to be as far away from the connecting piece 46 as possible, and the distance A shown in FIG. 1(a) is made as wide as possible. In other words, if this interval A is widened, the deflection of the locking side piece 24 will increase, and the locking side piece 24 will bend when the wiring device J%8 is attached or detached.
The wiring device 8 can be smoothly attached and detached by the bending of 4. However, if the deflection of the locking side piece 24 is increased as described above, it becomes easier to attach and detach the wiring device 8, but when the wiring device 8 attached to the plate frame 21 is pushed from the front side, the locking side piece 24 The engagement side piece 24 tilts so that the back side of the wiring device 8 opens outward, and there is a risk that the wiring device 8 may fall off from the plate frame 21. Therefore, in this embodiment, FIG.
), the locking side piece 2 is attached to the back surface of the locking IF hole 16
