The mounting piece mounted on the opening edge of the embedding hole formed for embedding the wiring device is protruded from the outer side surface of each mounting piece in a direction orthogonal to the side surface of each mounting piece. The pivot piece for pivotally coupling the pivot piece of the piano handle of the piano handle switch may be formed on the mounting piece.

[Operation] According to the present invention, as described above, each set of locking holes uses one of the locking holes adjacent to the other set of locking holes.
Even when individual wiring devices are mounted, the wiring device can be mounted at the center of the decorative plate frame.

Embodiment 1 FIGS. 1 to 5 show an embodiment of the present invention. As shown in FIG. 1, the mounting frame 1 of this embodiment has a rectangular shape, and has an opening formed at the center to expose the operation surfaces of the two wiring devices 2 (having a length of approximately two ends in the direction of both ends). 46 mm), ear pieces 11 are formed on both ends, respectively, and fixing holes 10 for screwing the mounting frame 1 to the wall surface of the ear pieces 11, and the wiring device 2 together with the mounting frame 1 are embedded in the wall surface. A screw hole 20 for fixing the plate 3 (see FIG. 4) to be used, and a mounting hole 21 for attaching a clamp are formed. And then
Plate-shaped mounting pieces 12 are vertically provided from both side pieces of the mounting frame 1. The mounting piece 12 includes a wiring device 2 in the opening of the mounting frame 1.
The locking holes 13a and 13b are formed in such a manner that a pair of locking claws 23a (or 23b) formed respectively on both side surfaces of the body of the wiring device 2 are respectively removably locked in a state where the two are fitted. A set is drilled. That is, in FIG.
a and 13b constitute one set, and the wiring device 2 is inserted into the opening of the mounting frame 1.
When two of them are fitted, these pairs of locking holes 13a and 13b make a pair of locking claws of the corresponding wiring device 2 23a (or 23b).
It is drilled at a position where it can be locked. However, the mounting frame 1 shown in FIG. 1 is made of synthetic resin, and the above configuration also includes the conventional synthetic resin mounting frame 1.

The features of the present embodiment will be described below. In the case of the present embodiment, the locking holes 13b are formed symmetrically with respect to the center line of the mounting frame 1 in the direction in which the wiring devices 2 are continuously provided, and the intervals are set to the locking claws 23a (or 23b). That is, the locking hole 13b is formed to be longer than the locking hole 13a, and the dimension L1 between the locking holes 13b is matched with the dimension L3 between the locking claws 23a (or 23b) of the wiring device 2. When one wiring device 2 is attached using the locking hole 13b, the wiring device 2 is attached to the wiring device 2 of the mounting frame 1.

When attaching the two wiring devices 2 to the mounting frame 2,
Can be attached in series.

By the way, in the case of FIG. 1, the mounting frame 1 made of synthetic resin is shown, but it goes without saying that it may be made of metal as shown in the conventional example of FIG. 10 (b). The decorative plate frame 4 has a square frame shape shown in FIG.
A round frame or a rectangular frame shown in FIG. 3 can be used, and can be designed to match the room in which the wiring device 2 is installed. FIG. 4 shows a cross section when a piano handle switch is buried in a wall using the mounting frame 1 of the present embodiment. In addition, the piano handle switch is a push button switch 25 in which when the push button handle 24 is pressed, the internal reversing mechanism is reversed and the contact is switched, and one end is pivotally mounted on the outer surface of the push button switch 25. When the other end is pressed in a piano touch manner, it functions as a piano handle 26 for pressing the push button handle 24 of the push button switch 25. FIG. 5 is a front view of a case where two piano handle switches are mounted on a wall surface using a decorative plate frame 4 having a round frame, a rectangular frame, and a square frame.

Embodiment 2 FIGS. 6 to 8 show another embodiment of the present invention. The present embodiment particularly relates to an improvement of a mounting frame 1 in which a piano handle switch is mounted as a wiring device 2.

By the way, when the piano handle switch is mounted on the wall using the mounting frame 1 of the first embodiment or the conventional mounting frame 1, there are the following problems. That is,
In the piano handle switch, the width of the piano handle 26 is made larger than the width of the mounting frame 2 in order to match the width dimension of the piano handle 26 with the opening dimension of the decorative plate frame 4. The piano handle 26 is pivotally attached to the push button switch 25 as shown in FIG. 12 so that the piano handle 26a can be touched by the piano. For this reason, the push button switch 25
(A in FIG. 12 (a)) between the pivotal support piece 26a pivoted at the position and the portion where the piano handle 26 presses the push button handle 24.
l3) is shortened, and the stroke (S in FIG. 12 (b)) when the piano handle 26 is pressed is increased, and in this case, the end opposite to the pressed portion jumps greatly (the amount of this jump). (Indicated by l1 in FIG. 12 (b)), there is a problem that the operation feeling is deteriorated, and when the piano handle 26 is not pressed, the amount of protrusion from the decorative plate frame 4 on the pressing portion side also increases (protrudes). The amount is indicated by l2 in FIG. 12 (a)), and there was a problem that the appearance was impaired.

Therefore, in the present embodiment, as shown in FIG.
A mounting piece 14 to be mounted on the opening edge of an embedding hole (see FIG. 8 (b)) 30 formed for embedding the mounting member is extended outward from both mounting pieces 12 and Piano handle 26 on table 14
A pivotal connection portion 15 for pivotally connecting the pivotal support piece 26a is formed. As shown in FIG. 8, the pivot portion 15 has an insertion hole 16 into which the pivot piece 26a of the piano handle 26 is inserted, and a substantially L-shaped contact piece 17 that contacts the base of the pivot piece 26a. The pivotal support piece 26a inserted into the insertion hole 16 is attached to the mounting frame 1 by engaging its claw with a ridge 18 formed on the inner surface outside the insertion hole 16, and the piano handle 26 is pivot piece 26a and abutment piece 1
It rotates about the contact point with 7 as a fulcrum. Here, the pivot portion 15 formed at the center is formed in such a size that the pivot portions 26a on the center side of the two piano handles 26 are pivoted together. 8, from the right end of the piano handle 26, that is, from the lower surface near the pressing end of the piano handle 26,
A pair of retaining pieces 26b for suspending the push button switch 25 are provided vertically, and the retaining pieces 26b are inserted into insertion grooves 28 formed in the body 27 of the push button switch 25, and the piano handle 26 is pressed. The operation end side is also attached to the push button switch 25. The retaining piece 26b has a claw formed at the tip of the retaining groove 26b.
8 to prevent it from slipping out
It can be moved up and down within 28. Therefore, the piano handle
When the pushing operation end of the pushing button 26 is pushed, the piano handle 26 rotates around the contact point between the pivot piece 26a and the contact piece 17, and pushes the push button handle 24 of the push button switch 25. If the piano handle 26 is pivotally supported on the mounting frame 2 in this manner, the distance between the pivotal support portion of the piano handle 26 and the portion pressing the push button handle 24 can be increased,
The stroke of the pressing operation end can be reduced, and at this time, the amount of bouncing of the pivot handle 26a of the piano handle 26 can be reduced, so that the operation feeling of the piano handle switch can be improved and the piano handle 26 can be pressed. If not, the amount of protrusion from the decorative plate frame 4 on the pressing operation end side is also small, and the appearance can be improved. When the mounting piece 14 is protruded outward from the mounting piece 12 as described above, the mounting piece 14 is mounted on the opening edge of the embedding hole 30 formed for embedding the piano handle switch in a wall or the like. The pieces 14 are placed in a manner of climbing up, so that there is also an effect that the mounting frame 1 can be prevented from being deformed when the mounting frame 1 is fixed with fixing screws.

[Effect of the invention]

A pair of locking claws are respectively protruded from both sides of the body at predetermined intervals corresponding to both end directions of the mounting piece, and the two wiring devices are fitted in the opening portions. Each of the locking claws protruding from the body is locked separately.
The two locking holes are drilled in the longitudinal direction of the mounting piece, and the center line bisecting the opening of the wiring device in both ends is aligned with the center line bisecting the opening in both ends. With the wiring device fitted in the opening, the locking claw of the wiring device can be locked in two locking holes at the center of the four locking holes. The length of the mounting piece in the direction of both ends of the mounting hole is set, and the distance between opposing side edges of two adjacent locking holes of the four locking holes is determined by the distance of the device of the wiring device. Since the distance between the opposing side edges of the pair of locking claws projecting from the body is matched, the pair of locking claws of the wiring device are locked in the two locking holes located at the center side and fixed. , One wiring device can be placed in the center of the opening, so that the decorative plate frame It can be attached to the central, there is the advantage that can be attached may look good in the case of mounting one wiring accessories.

In particular, in a mounting frame for mounting a piano handle switch as the wiring device, a mounting piece mounted on an opening edge of an embedding hole formed for embedding the wiring device is positioned outside of each of the mounting pieces. A projecting portion is provided from the side surface in a direction perpendicular to the side surface of each mounting piece, and a pivoting portion for pivotally attaching the pivotal support piece of the piano handle of the piano handle switch is formed on the mounting piece. The distance between the pivoting part of the switch and the part pressing the push button handle of the piano handle switch can be lengthened, so that the stroke of the piano handle can be reduced, the operational feeling can be improved, and the makeup of the piano handle can be improved. There is also an advantage that the amount of protrusion from the plate frame can be reduced, and thus the appearance can be improved.
