Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a structure for fixing a mounting frame for a wiring device to a wall surface.

[Background technology]

Conventionally, when attaching a wiring device to a thick wall such as a gypsum board wall, a mounting frame, which is a portion to which the wiring device is fixed, is first fixed to the wall surface. To fix the mounting frame, conventionally, wall fittings 9 as shown in FIG. 1 have been used. As shown in FIGS. 1 and 2, the wall scissors 9 are as follows:
It has a shape with an opening 9a in the center, and the mounting frame 1 is placed across a hole 5 for mounting a wiring device drilled in the wall 4.
It is designed so that it can be attached from the back side of the wall 4 so as to face it. Projecting pieces 1 are provided on the upper and lower inner peripheral edges of the frame 9b formed around the entire circumference of the opening 9a so as to project into the hole 5 of the wall 4.
0 and 10 are formed. Each protruding piece 10 is provided with a screw hole 11. A metal fixture fixing piece 12 having a pointed end 12a that can be inserted into the peripheral wall of the hole 5 is provided on the side of the lower protruding piece 10 so as to be bendable in the direction in which the pointed end 12a is inserted. A small plate piece 16 extends from one side of the opening 9a via bendable long narrow parts 16a, 16a. When fixing the mounting frame 1, as shown in Fig. 2, first place the wall clip 9 on the back side of the wall 4, pull out the plate piece 16, and hang it on the front side of the wall 4 to secure the wall 4. to pinch. Further, the tip 12a of the metal fitting fixing piece 12 is pushed and bent using a tool (shown in the drawing with chain lines), etc., and inserted into the circumferential wall of the hole 5, thereby temporarily fixing the wall fitting 9 to the wall 4. Then, the screw insertion holes 1a, 1 of the mounting frame 1
The mounting frame 1 is fixed to the wall 4 by inserting screws (not shown) through a and screwing them into each screw hole 11 of the wall fitting 9. However, such a mounting structure requires the work of pulling out the plate piece of the wall fitting and inserting it into the wall, inserting the tip of the fitting fixing piece into the hole, and screwing the mounting frame to the wall fitting. Therefore, there was a problem that the work was time-consuming.

[Purpose of invention]

Therefore, an object of this invention is to provide a fixing structure for a mounting frame that can easily fix the mounting frame to a wall.

[Disclosure of invention]

In order to achieve the above purpose, the inventor completed this invention after extensive study.

This invention has a structure in which a wiring device mounting frame is fixed to a wiring device mounting hole drilled in a wall.
A holding member disposed on the back side of the wall so as to face the mounting frame across the hole, and an outwardly bent spring plate locked between the holding member and the mounting frame, The frame has screw insertion holes at both ends thereof, and has locking holes on both sides of each screw insertion hole for receiving one end of an outwardly bent spring plate, and the holding member holds the screws of the mounting frame. It has a screw hole at a position corresponding to the insertion hole, into which a screw inserted through the screw insertion hole of the mounting frame is screwed, and a locking hole is provided at a position corresponding to the locking hole of the mounting frame. The other end of the spring plate is received in these locking holes, and as the screw rotates, the spring plate is compressed between the mounting frame and the holding member and further bent outward, so that the bent portion thereof is compressed between the mounting frame and the holding member. The gist of the present invention is a fixing structure for a mounting frame, which is characterized in that the mounting frame is fixed to the wall under pressure by coming into contact with the back surface of the wall. Hereinafter, this will be explained in detail based on drawings showing examples thereof.

The fixing structure of the mounting frame according to this invention is similar to the conventional one, as shown in FIG. The wiring device mounting frame 1 is fixed to a wall, and includes locking holes 1b, 1b for receiving one end of a spring plate 8 bent outward.
The mounting frame 1 has an opening 2 inside, into which a wiring device 3 is received and fixed.
As shown in FIG. 4, the fixing structure of the mounting frame 1 according to this invention is such that the mounting frame 1 is fixed on the back side of the wall 4 so as to face the mounting frame 1 across the hole 5 for mounting wiring equipment drilled in the wall 4. A pressing member 6 is provided. This holding member 6 is a plate having an opening 6a in the center for insertion of a wiring device. Further, the holding member 6 has screw holes 6b at positions corresponding to the screw insertion holes 1a, 1a of the mounting frame 1, and screws 7 are inserted into each of the screw holes 6b from the screw insertion holes 1a of the mounting frame 1.
is screwed in. The mounting frame 1 has locking holes 6c at positions corresponding to the locking holes 1b, and the other ends 8a of the spring plates 8 bent outward are received in these locking holes 6c. When fixing the mounting frame 1, first, as shown in FIG. 4, the holding member 6 is inserted from the front side of the wall 4 and placed on the back side of the wall 4. When screws 7 and 7 are rotated, as shown in Figure 5,
The spring plates 8 (only two plates are visible in the figure) are compressed between the mounting frame 1 and the pressing member 6, and are further bent (inflated) outward. Each of the bent portions 8b comes into contact with the back surface of the wall 4, and these bent portions 8b and the mounting frame 1 sandwich the wall. Thereby, the mounting frame 1 is fixed to the wall 4 under pressure.
In this way, the fixing structure of the mounting frame according to this embodiment makes it very easy to fix the mounting frame by simply inserting the combination of the mounting frame, holding member, spring plate, and screw into a hole in the wall and turning the screw. can be done.

In the embodiment, the holding member constituting the fixing structure of the mounting frame according to this invention was a circular plate having an opening in the center for insertion of a wiring device. However, the shape may also be rectangular. Further, it is not necessarily necessary to have an opening as described above in the central portion.

Once the mounting frame is fixed to the wall, a wiring fixture is fixed to the mounting frame either before or after. after that,
A plate or the like is attached to the mounting frame.

[Effect of idea]

As described above, the fixing structure of the mounting frame according to this invention is such that both the mounting frame and the holding member are fixed by rotating the screw that is inserted through the screw insertion hole of the mounting frame and screwed into the screw hole of the holding member. The spring plate that is bent outward is compressed between the two and further bent outward, and the bent part comes into contact with the back surface of the wall, whereby the mounting frame is fixed to the wall under pressure. Since the mounting frame can be fixed simply by rotating the screw, the work of fixing the mounting frame does not require much time and effort, and the work is extremely simple.
