Thereafter, the plate is fitted into the mounting frame by engaging the engagement piece of the plate with the engagement portion. and,
Even if the mounting opening is small and the engagement part of the mounting frame faces the mounting surface, the plate surface of the engagement part bulges out to the front side and a recess is formed on the back side, so the engagement piece of the plate can be engaged with the recessed part on the back of the engaging part, and the plate can be attached.

(Example) An embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a mounting frame, and this mounting frame 1 includes a main body part 2 formed of metal into an elongated rectangular plate shape, an elongated rectangular instrument mounting opening 3 formed in the middle part of the plate surface of this main body part 2, and this An opening 4 in a mounting surface 4 of a structure etc. is located at both ends of the instrument mounting opening 3.
A pair of fastener mounting holes 7, 7. These fixing tool mounting holes 7
, 7 are provided with mounting holes 8.8 formed for plate mounting.

This mounting frame 1 includes an engagement piece 10 that engages with an engagement hole (not shown) provided on one side of a device 9 such as an outlet, and an engagement hole (not shown) provided on the other side of the device 9. ) Three sets of instrument fixing means 1 equipped with a caulking operation part 11 to be engaged with the
2 are provided.

Then, a notch 30 is provided at the middle part of the edge at the end of the main body 2 outside the fixing tool mounting hole 7 of the mounting frame 1, and in this notch 30, the plate surface faces the front side, and a concave portion bulges on the back side. 13 is provided.

This engaging portion 14 is located at the top of the mounting frame 1 in FIG.

Two notches 30 are formed at the lower end. When attaching the mounting frame 1 to the mounting portion 6 of the mounting surface 4, this engaging portion 14 is provided so that even if the upper and lower ends of the main body portion 2 face the mounting surface 4, there is no gap between the recessed portion 13 and the mounting surface 4. formed to occur.

Reference numeral 15 denotes a plate, which is made of, for example, synthetic resin, and has a window hole 16 in its middle portion through which the instrument 9 is exposed. This plate 15 has four locking pieces 17 on the back surface that engage with the engaging portions 14 of the mounting frame 1.
It is formed to fit into the

This locking piece 17 has a tip shaped like a hook, and is configured to elastically engage with the engaging portion 14 and to be released from the engagement by pushing the plate 15 outward.

Reference numeral 18 denotes a fixing screw, and the fixing screw 18 is inserted into the fastener mounting hole 7 of the mounting frame 1 and screwed into the mounting portion 6 of the wiring box 5, thereby fixing the mounting frame 1 to the mounting surface 4.

Reference numeral 19 denotes an electric wire wired in the wiring box 5 and connected to the appliance 9.

Next, the operation of this embodiment will be explained. To attach the mounting frame 1 to the mounting surface 4, connect the electric wire 19 wired to the wiring box 5 to the fixture 9 attached to the mounting frame 1, insert the mounting screw 1B into the fastener mounting hole 7, and then attach the wiring box 5 to the mounting frame 1. The mounting frame 1 is mounted on the mounting surface 4 by screwing into the mounting portion 6 of the mounting frame 1 .

Next, the plate 15 is directly fitted into the mounting frame 1 by engaging the locking piece 17 of the plate 15 with the engaging portion 14 of the mounting frame 1.

At this time, since the engaging portion 14 of the mounting frame 1 bulges out the plate surface of the main body portion 2 toward the front side and forms the recessed portion 13 on the back side, the tip of the locking piece portion 17 of the plate 15 is engaged. Since it fits into the recess 13 on the back surface of the joint part 14, even if the opening 40 of the mounting surface 4 is small and the engaging part 14 of the mounting frame 1 faces the mounting surface 4, the locking piece 17 of the plate 15 will not fit into the mounting frame. It can be engaged with the first engaging portion 14 .

By the way, in order to be able to directly attach the plate 15 to the mounting frame 1, dimensional accuracy is required especially in the upper and lower directions of the vertically long main body part 2 shown in FIG. It is necessary to deal with errors.

The material width required for manufacturing the mounting frame is the main body part 2 of this mounting frame 1.
Although the dimensions are in the upper and lower directions, there are naturally variations in the dimensions in the material width, and the device fixing means 1 processed in the press process.
2 and the fastener attachment holes 7.7, etc., the parallelism etc. of the engaging portion 14 do not precisely match, and furthermore, variations in the dimensions of the material may be added.

In this state, not only is there a possibility that the plate 15 cannot be attached to the attachment frame 1 in a normal position, but even if it is attached, problems such as the instrument 9 being attached at an angle occur.

Therefore, in order to eliminate such problems, in the pressing process in the manufacturing process of the mounting frame 1, a notch 30 is provided at the middle of the edge at the upper and lower ends of the main body 2, and at this notch 30, By providing the engaging portion 14, the dimensional accuracy between the cutout portions 30 can be improved, and the parallelism etc. of the instrument fixing means 12 and the engaging portion 14 can be matched.

Although the present invention has been described with respect to the above embodiments, the present invention is not limited thereto. For example, the mounting frame may be attached directly to the mounting surface.

[Effects of the Invention] As detailed above, the present invention is for mounting a plate by fitting it into a mounting frame, and the mounting frame has a plate surface bulging toward the front side and a recessed portion on the back side at both ends of the main body. Since the plate is provided with a locking piece that engages with the engaging part, the opening in the mounting surface is small, and the mounting frame can be mounted with the engaging part facing the mounting surface. The plate can be attached to the mounting frame even if the

In addition, the engagement part of the mounting frame is provided with a notch in the middle of the edges at both ends of the main body, and is formed at this notch, so that it can be attached to a metal mounting frame that is generally used for attaching instruments. Since only machining is required, the structure is simple and easy to manufacture, and the dimensional accuracy of the engaging portion can be high, making it possible to securely attach the plate.
