Description

[Detailed Description of the Invention] This invention relates to a device for mounting a control panel to a housing of, for example, an air conditioner.

This type of control panel generally consists of a support board that supports operating members such as switches, and a decorative board that is attached to the front side of this support board. Conventionally, this is done as follows. That is, screw insertion holes are provided at the four corners of the support board, and two screw insertion holes arranged diagonally in the decorative board are drilled, and first, among the screw insertion holes in the support board, the screw insertion holes on the decorative board side are Screw the support board to the casing using the two screw insertion holes on the opposite diagonal, then match the two screw insertion holes on the decorative board to the remaining two screw insertion holes on the support board. After that, the decorative board is fastened together with the support substrate to the housing. However, with this method, the screw insertion holes on the support board side and the screw insertion holes on the decorative board side are often misaligned due to the accumulation of dimensional errors during manufacturing, and the hole positions must be corrected or forced. This involved the troublesome work of having to align the position and then tighten the screws.

In addition, when installing the above-mentioned support board, if you first screw in the screw insertion hole on the same diagonal as the screw insertion hole on the decorative board side, you will not be able to screw in the decorative board later, so attach the support board again. Must be reinstalled.

This invention was devised in view of the above-mentioned drawbacks of the conventional art, and its purpose is to provide a control panel mounting device that is easy to align with the housing and can be implemented with simple work.

Hereinafter, this invention will be described in detail with reference to an embodiment shown in the accompanying drawings.

1 and 2 illustrate a state in which a control panel consisting of a combination of a support substrate 1 and a decorative board 2 is attached to, for example, a housing 3 of an air conditioner. In this embodiment, the casing 3 includes a top plate 5 and a bottom plate 6 that are vertically symmetrically assembled with a side plate 4 in between, and flanges 7 and 8 that are bent at right angles to face each other at their peripheral edges. It's summery.
In this case, the flange 7 on the top plate 5 side is provided with a first attachment hole 9 and a first slit hole 10, while the flange 8 of the bottom plate 6 is provided with a second attachment hole 11. The support substrate 1 is made of a plate member formed so that an operating member 12 such as a rotary switch can be attached to the back side thereof, and has first bent portions at both ends that are compatible with the flanges 7 and 8. 13 and a second bent portion 14 are provided, respectively. The first bent portion 13
It has a bent piece 15 that is bent at a substantially right angle from one end toward the flange 7 side, and this bent piece 15
The end portion of is divided into two parts, one of which is a tongue piece 1 which is bent upward parallel to the flange 7.
6, and the other end is a first locking piece 17 bent downward so that it can be locked in the first slit hole 10. And folded piece 1
5 is provided with a second slit hole 18, and the tongue piece 16 is provided with a first screw insertion hole 19 that matches the first mounting hole 9. The second bent portion 14 is connected to the flange 8 at the other end of the substrate 1.
It consists of a U-shaped body that is bent so as to protrude toward the side, and a second screw insertion hole 21 that matches the second mounting hole 11 is bored in the bottom part, that is, a flat part 20 parallel to the flange 8. Further, a third slit hole 23 is formed in the folded part 22 which is continuous with the flat part 20. The decorative board 2 is
It consists of a plate member formed in a size that covers the front side of the support substrate 1, and the first bent portion 13 of the support substrate 1 is attached to one end side of the plate member.
At the same time, a mounting piece 24 that is fastened together with the flange 7 of the top plate 5 is provided in a row. In this case, the mounting piece 24
is an L-shaped member including a horizontal bent part 25 and a vertical bent part 26, and the horizontal bent part 25 has a second engaging part cut downward so as to engage with the second slit hole 18. A stopper 27 is provided, while
A third screw insertion hole 28 that matches the first screw insertion hole 19 is bored in the vertical bent portion 26 .
Further, on the other end side of this decorative board 2, a third engaging member is formed by bending downward so as to engage in the third slit hole 23 at the end of the horizontally bent bent part 29. A stopper 30 is provided. In this embodiment, the decorative plate 2 is provided with a through hole 3 through which the rotary operation shaft 31 of the operation member 12 is inserted.
2 is drilled.

In this mounting device, the control panel is mounted to the housing 3 in the following manner. It is assumed that the operating member 12 is attached to the back surface of the support substrate 1 in advance.

First, the first locking piece 17 formed on the support substrate 1 is hooked onto the first slit hole 10, and the support substrate 1 is
By attaching the upper part of the board to the flange 7 of the top plate 5, aligning the second screw insertion hole 21 with the second mounting hole 11, and tightening the screw 33, the supporting board 1
The lower part of the base plate 6 is fixed to the flange 8 of the bottom plate 6. next,
The second locking piece 27 and the third locking piece formed on the decorative board 2
Each of the locking pieces 30 is engaged with a second slit hole 18 and a third slit hole 23 formed in the support substrate 1, respectively, and the decorative board 2 is attached to the support substrate 1 so as to be hooked thereon. After that, align the third screw insertion hole 28 and the first screw insertion hole 19 with the first mounting hole 9, and insert the screw 3 into those holes.
4 is inserted and tightened, the upper parts of the decorative board 2 and the support substrate 1 are fastened together with the flange 7 of the top plate 5. In this way, the control panel consisting of the combination of the support substrate 1 and the decorative board 2 can be easily attached using two screws 33 and 34. In that case, as illustrated in FIG. , a suitable cushion material 35 may be interposed between the support substrate 1 and the decorative board 2. According to this, it is possible to effectively prevent slight vibrations of the control panel caused by vibrations generated from a compressor (not shown) installed in the housing 3, etc.

As is clear from the above description of the embodiments, according to this invention, the support substrate and the decorative board that constitute the control panel can be easily attached to the housing with just two screws. In addition, since the support board is temporarily fixed to the casing, the decorative board is hooked to the support board, and both are fastened together to the casing, some dimensional errors may occur during manufacturing. However, it is extremely practical as it allows for easy installation work.
