DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an appliance mounting device with a simple structure for attaching appliances such as outlets and switches to a panel.

(Prior Art) Conventionally, as an instrument mounting device, a mounting frame is brought into contact with the inner surface of the peripheral edge of a window hole formed in a panel, and an instrument mounting frame is brought into contact with the outer surface of the peripheral edge of the window hole. pre-attached to the device mounting frame by pinching the peripheral edge of the window hole with the
Alternatively, various proposals have been made in which a device that has been attached later is attached to the panel. For example, in the method disclosed in Japanese Utility Model Application Publication No. 52-52100, a wire spring is provided on the mounting frame that is inserted into the inside through the window hole of the panel, and the wire spring is used to temporarily fix the mounting frame during the insertion. Next, the instrument mounting frame is brought into contact with the outer surface of the peripheral edge of the window hole, and the screw is tightened to clamp the peripheral edge of the window hole between the mounting frame and the instrument mounting frame, and the instrument is mounted.

Further, in the method disclosed in Japanese Utility Model Application Publication No. 51-153491, an adhesive layer is provided on the mounting frame and the mounting frame is temporarily fixed inside the window hole by adhesion.

Furthermore, in the device disclosed in Japanese Patent Application Laid-Open No. 55-122410, biting teeth that can bite into the end face of the window hole are provided on the upper and lower pieces of the frame, and after the frame is brought into contact with the inside of the window hole,
A screwdriver is used to deform the biting teeth so that they bite into the end face of the window hole.

Furthermore, the one published in Utility Model Publication No. 38-21042 is
The mounting frame is formed by a holding frame and a device mounting frame having a screw hole for a wiring device mounting plate, and the holding frame has two pairs of elongated tongue pieces in the middle part on both sides, and the device mounting frame is formed by a holding frame. A recess is provided at a position corresponding to the elongated tongue piece, and the holding frame is brought into contact with the inner peripheral edge of the window hole, and the instrument mounting frame is brought into contact with the inner surface of the window hole, so that the elongated tongue piece is attached to the instrument mounting frame. It is bent and attached to a wall surface through a recess. That is,
In this device, the mounting frame as an alternative to a switch box is composed of two parts: a holding frame and an instrument mounting frame.

(Problems to be Solved by the Invention) The method disclosed in Japanese Utility Model Application Publication No. 52-52100 uses a wire spring, which not only requires extra material, but also requires processing to bend the wire spring into a predetermined shape. There was also the problem that it was necessary and expensive.

The product shown in Japanese Utility Model Application Publication No. 51-153491 does not necessarily have a surface condition on the inside of the periphery of the window that allows for good adhesion, so temporary fixing may not be effective and there is often a problem with the product falling off. Ta.

The device disclosed in Japanese Unexamined Patent Publication No. 122410/1983 uses a screwdriver to deform the upper and lower two biting teeth and is attached, making the attachment operation cumbersome. In addition, the window hole in the panel only needs to be formed with an opening size that allows the installation of the device mounting frame that holds the device, and generally the dimensional accuracy is low, and this type of panel has a cutting tooth at the top that bites into the top edge of the window hole. There may be cases where it is not possible to do so, and temporary fixing may not be effective. moreover,
Since this device has a complicated shape for the driver insertion opening, etc., even if these are integrally molded with the frame, there is a problem that the mold becomes complicated and expensive.

What is shown in Japanese Utility Model Publication No. 38-21042 is a mounting frame that replaces a switch box and is formed of two parts: a holding frame and a device mounting frame.
There are a large number of parts, and installation to the panel is also troublesome.

In addition, in this case, the holding frame as a mounting frame and the instrument mounting frame must be firmly fixed to the panel with elongated tongue pieces. Therefore, four elongated tongue pieces are required, and both Since it has to be bent and fixed to prevent it from falling off, there are disadvantages such as the structure becomes complicated and the installation operation becomes troublesome.

The present invention aims to solve the problems of each of the above-mentioned conventional techniques, and has a simple structure, can be provided at low cost, and can securely temporarily fix the mounting frame by preventing it from shifting or falling. It is an object of the present invention to provide an instrument mounting device that allows easy and reliable mounting of an instrument mounting frame holding an instrument mounting frame.

[Structure of the Invention] (Means for Solving the Problems) The instrument mounting device of the present invention includes a pair of arm portions each having a screw hole and facing each other, and a connection connected to the ends of the arm portions. part, a protrusion provided on the arm part and locked to the end face of the window hole in the direction in which the window hole is intended to fall when it comes into contact with the inner surface of the peripheral edge of the window hole inserted inward from the window hole of the panel; and the connecting part; The window has a mounting frame that is temporarily fixed to the panel and includes a protrusion that is bendable toward the outer surface of the peripheral edge of the window hole, and a screw insertion hole that corresponds to the screw hole of the arm part. An instrument mounting frame that holds an instrument that is in contact with the outer surface of the peripheral edge of the hole, and the mounting frame that is inserted through the screw insertion hole of the instrument mounting frame and engaged with the screw hole of the mounting frame to be temporarily fixed. and a screw for clamping and fixing the instrument mounting frame to the peripheral edge of the window hole.

(Function) In the present invention, a mounting frame having a mounting frame having a screw hole in the arm portion is inserted into a window hole of a panel, and is brought into contact with the inner surface of the peripheral edge of the window hole. Then, the protrusion is engaged with the end surface of the window hole, and the protruding piece provided on the connecting portion is bent toward the outer surface of the peripheral edge of the window hole. At this time, in the present invention, since the protrusion locks (places or bites into) the end face of the mounting frame in the direction in which it is about to fall, it is reliably prevented from falling or shifting in the direction in which it is about to fall. In addition, by bending toward the outer surface of the peripheral edge of the window hole provided in the connecting part, this projecting piece is locked to the end surface of the window hole and further to the outer surface, so that it prevents lateral positional displacement and the inner side of the window hole. Falling due to falling down is reliably prevented. Moreover, the operation is simple, since the only operations required are locking the protrusion and bending the protrusion, and even if a screwdriver or the like is used to lock the protrusion, it is sufficient to simply hit the protrusion. In this way, after temporarily fixing the mounting frame to the inside of the panel, place the instrument mounting frame, which has screw insertion holes corresponding to the screw holes in the mounting frame and holds the instrument, against the outer surface of the window hole periphery, and then screw the Insert it into the screw insertion hole of the instrument mounting frame,
By engaging with the screw holes of the mounting frame, the instrument mounting frame and the mounting frame are fixed to each other by sandwiching the panel.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a mounting frame that is inserted into the inside of the window hole 3 of the panel 2 and comes into contact with the inner surface of the peripheral edge of the window hole 3. It has a connecting part 21 connected to the end of the part 20, has a through hole 4 in the middle part, and is formed into a rectangular shape. A pair of protrusions 6 having screw holes 5 are provided on the arm portions 20, 20 of the mounting frame 1. Further, the mounting frame 1 is provided with an end face (of the peripheral edge of the window hole 3 of the panel 2) in the direction in which the mounting frame 1 is about to fall ( A protrusion 7 that is engaged with the lower end surface (in FIG. 4) and an elongated plate-shaped protrusion 8 that can be bent on the outer surface of the peripheral edge are integrally provided on the inner surface of the connecting portion 21. . The protruding piece 8 has two small diameter portions in the middle in order to facilitate bending. Reference numeral 9 denotes a device mounting frame, which holds the wiring device 10 and has a screw insertion hole 12 corresponding to the screw hole 5 of the mounting frame 1. The device attachment frame 9 may be formed by fixing a pair of legs to both ends of the wiring device 10. Reference numeral 11 denotes a screw, and this screw 11 is inserted through the screw insertion hole 12 of the instrument mounting frame 9 and engaged with the screw hole 5 of the mounting frame 1 to connect the temporarily fastened mounting frame 1 and the instrument mounting frame 9 to the window hole 3. It is clamped and fixed to the peripheral edge.

Next, the operation of this embodiment will be explained. Insert the mounting frame inside the window hole 3 with the protrusion 7 facing down,
It comes into contact with the inner surface of the peripheral edge of the window hole 3. Next, protrusion 7
If necessary, use a tool such as a driver or a hammer to hit the protrusion 7 from above to lock the protrusion 7 to the end surface of the peripheral edge of the window hole 3. This locking may be done by simply placing the protrusion 7 on the end surface without biting into it. Next, the projecting piece 8 is bent to the outer surface of the peripheral edge of the window hole 3, and the peripheral edge of the window hole 3 is sandwiched between the projecting piece 8 and the first fixture. Therefore, the movement of the mounting frame 1 in the direction in which it is about to fall, in the direction crossing this, and in the direction in which it is about to fall into the inside of the window hole is restricted by the protrusion 7 and the protrusion piece 9, respectively, and the mounting frame 1 is in a temporarily fixed state. is maintained. Note that the connecting portion 21 provided with the protruding piece 8
Although it is somewhat weak against the force directed toward the opposite side, it is not enough to cause the protrusion 7 to bite or the peripheral edge of the protrusion 8 to be pinched, and to cause the protrusion to shift or fall. Naturally, force in this direction is not applied, or even if it is applied, it is weak. Next, wiring equipment 10
The instrument mounting frame 9 fitted with the instrument mounting frame 9 is brought into contact with the outer peripheral edge of the window hole 3, and the screw 11 is inserted into the screw hole 5 through the screw insertion hole 12 and tightened, thereby creating a space between the mounting frame 1 and the instrument mounting frame 9. The peripheral edge of the window hole 3 is held between the two, and the installation is completed. Therefore, when temporarily fixing the mounting frame 1, unlike the case where an adhesive layer is provided, movement in substantially all directions is restricted by the projections 7 and the protrusions 8 as described above. Because it is done,
The temporarily fixed state is reliably maintained. Moreover, the projecting piece 8 and the protrusion 7 are integrally provided on the mounting frame 1, and the shape thereof can be simplified, so that the structure can be provided with a simple structure and at a low cost.

Moreover, the shape of the mounting frame may be U-shaped.

[Effects of the Invention] As detailed above, the present invention is a device in which the peripheral edge of a window hole of a panel is held between a mounting frame and an instrument mounting frame holding an instrument, and the present invention is a device that is inserted into the inside of the window hole. It is attached to the arm part of the mounting frame with a protrusion that is latched to the end face of the window hole in the direction in which it will fall when the mounting frame comes into contact with the inner surface of the window hole, and a protrusion provided on the connecting part. By temporarily fixing the frame to the panel and reliably preventing the frame from falling or shifting, it is possible to securely and easily temporarily fix the frame to the window hole. Therefore, the mounting frame and the entire device can be provided at low cost. In addition, even if the dimensional accuracy of the window hole is low, it can be installed using the protrusions and protrusions.
By being able to securely temporarily fasten the mounting frame, the installation work of the instrument mounting frame holding the instrument into the window hole is as easy as the installation to the switch box, and
This can be done reliably.
