The coupling member 24 is constructed between the pair of side members 22 and 22 and between the side members 22 and 22 and the intermediate member 23 connected to each other.
[0012]
More specifically, as shown in FIG. 2, each side member 22 is formed of a hard synthetic resin in a substantially U-shape as a whole, and a connecting boss 222 is provided at the tip of one free end 221. A boss hole 224 into which the boss 222 can be inserted and connected is formed at the distal end of the other free end 223, and the decorative plate 3 is fitted inside the vertically long base end 225. A stepped portion 226 is formed.
[0013]
Locking holes 227 of locking portions 241 formed at both ends of the coupling member 24 shown in FIG. 3 are formed at the inner corner where the base end portion 225 intersects with the free end portion 221 and the free end portion 223. In particular, the overhanging length a of the free end 221 excluding the boss 222 is substantially ½ of the wiring device mounting interval b (see FIG. 1).
[0014]
Further, as shown in FIG. 4, the intermediate member 23 is formed substantially in an I shape by a synthetic resin, and at the upper and lower ends of the vertically long base end portion 231, the same boss 232 as the boss 222 is provided at one end. The other end has the same boss hole 233 as the boss hole 224, and the length c excluding the boss 232 is substantially equal to the wiring device mounting interval b (see FIG. 1). It is formed symmetrically.
[0015]
Further, step portions 235 and 235 for fitting the decorative plate 3 flush with each other are formed on both side ends of the base end portion 231 of the intermediate member 23, and the base end portion 231 and the lateral members 234 and 234 Locking holes 238 of locking portions 241 formed at both ends of the coupling member 24 are formed at the respective inner corners where the crossings intersect.
[0016]
As shown in FIG. 1A, the boss hole 233 and the boss 232 of the intermediate member 23 facing each other are connected to the boss 222 and the boss hole 224 of the side members 22 and 22, respectively, and arranged opposite to each other. Locking portions 241 and 241 bent at both ends of the coupling member 24 are locked in the locking holes 227 and 238, and the side member 22, the intermediate member 23, and the side member 22 are sequentially connected to each other as shown in FIG. The plate frame 2 is formed as shown in FIG.
[0017]
As shown in FIG. 5, the plate frame 2 configured in this way is attached to a wiring device mounting box or a hollow wall mounting frame (not shown) disposed along the back side of the wall surface by a set screw 42. Wiring fixture mounting frames 4 and 4 to which the wiring fixture 5 is previously attached are respectively attached, and the insertion screw holes 41 of these wiring fixture mounting frames 4 are formed at the centers of the coupling members 24 forming the plate frame 2. The mounting screw 51 inserted through the hole 26 is screwed to place and fix the plate frame 2 on the surface (not shown) of the wall surface.
[0018]
Then, the decorative plates 3 formed individually corresponding to the respective mounting windows 21 are mounted on the two mounting windows 21 to which the respective wiring apparatus mounting frames 4 (wiring apparatuses 5) are respectively mounted (see FIG. 6). ).
[0019]
At this time, as shown in FIG. 7, engaging protrusions 32 projecting from the back surface of the decorative plate 3 are engaged with engaging recesses 25 formed at both ends of the coupling member 24 forming each mounting window 21. Thus, the decorative plate 3 can be attached and detached reliably and easily.
[0020]
In the present embodiment, since one decorative plate 3 is mounted on one mounting window 21 formed on the plate frame 2, only several types of decorative plates 3 are prepared in advance. For example, FIG. As shown in FIG. 2, the plurality of mounting windows 21 can be adapted to the type and arrangement of the wiring device 5, and a plurality of mounting windows 21 formed on the plate frame 2 are covered with a single decorative plate 3. Unlike the decorative plate 3 (see FIG. 9), it is not necessary to prepare many kinds of plates, which is very economical.
[0021]
10 is different from the above embodiment in that the plate frame 2 having one mounting window 21 is formed using only the pair of side members 22 and 22 without using the intermediate member 23. Thus, in this embodiment, the plate frame 2 having one mounting window 21 can be formed using only the pair of side members 22 and 22.
[0022]
FIG. 11 shows a different embodiment of the present invention, and the overall configuration is substantially the same as that of the previous embodiment, but the side members 22, 22 and the intermediate member 23 are connected to the locking hole 227 at the tip. The base end of the coupling member 24 having the locking portion 241 is integrally formed of synthetic resin.
[0023]
Therefore, the work for forming the plate frame 2 is easier than in the embodiment using the separate coupling member 24, and the number of parts is small, which is advantageous in terms of manufacturing and management.
[0024]
12 to 15 show still another embodiment of the present invention. The embodiment shown in FIG. 12 is the embodiment shown in FIGS. 1 to 8, and the embodiment shown in FIG. 11, each of the side members 22 has substantially the same configuration.
