BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an appliance device, such as a switch or an outlet, in which a plate is directly attached to a mounting frame provided with an appliance body.

0003

[Prior Art] For example, in wiring devices,
As described in Publication No. 238412, etc., a mounting frame to which a switch or outlet is attached is screwed to a recessed box that is embedded and fixed on a wall surface, etc., and a plate mounting frame is screwed to this mounting frame. The plate is fixed in place, and the plate can be attached to this plate attachment frame with a single touch.

[0004] The plate is attached by engaging an engaging portion at the tip of a locking leg protruding from the middle portion of the back surface of the plate with a locking portion of the plate mounting frame.

[0005]

[Problems to be Solved by the Invention] As mentioned above, conventionally,
A plate mounting frame was required to attach the plate to the mounting frame.

This is because the mounting positional relationship between the mounting frame and the plate that is directly mounted to the mounting frame in a one-touch manner changes.

In other words, in addition to the mounting position relationship when the back surface of the mounting frame and the back surface of the peripheral edge of the plate are joined to the same wall surface, for example, when wallpaper is pasted on the wall surface, the location of the embedded box is Because the wallpaper is cut, the back side of the mounting frame is directly connected to the wall surface, but the back side of the mounting frame and the back side of the peripheral edge of the plate are on the same side of the wall surface, where the back side of the peripheral edge of the plate is connected to the wallpaper. There is a relationship between the mounting positions when not joined. If the mounting positional relationship between the mounting frame and the plate changes in this way, even if you try to mount the plate directly to the mounting frame with a one-touch method, the change in the mounting positional relationship cannot be absorbed, so the locking legs of the plate will not fit into the mounting frame. It may not be possible to engage the plate, or a gap may be created between the plate and the wall surface, causing rattling.

[0008] The present invention has been made in view of the above points, and allows the plate to be directly attached to the mounting frame in a one-touch manner, and also absorbs changes in the mounting positional relationship between the mounting frame and the plate. , it is an object of the present invention to provide an instrument device that can reliably attach a plate to a mounting frame.

[Configuration of the invention]

0010

[Means for Solving the Problems] The present invention includes a mounting frame including an instrument main body and a locking portion, and an elastic locking leg protruding from the middle part of the back surface, and the tip of the locking leg is provided with a mounting frame provided with a locking portion. and a plate provided with an engaging portion that engages with the locking portion of the mounting frame so that the engaging position thereof can be adjusted.

[0011]

[Operation] In the present invention, the engagement portion of the elastic locking leg protruding from the middle portion of the back surface of the plate engages with the locking portion of the mounting frame, so that the plate can be directly mounted in a one-touch manner. Moreover, even if the mounting position of the plate is different from the mounting frame,
Since the engaging position of the engaging part with respect to the locking part is adjustable, the plate can be reliably mounted on the mounting frame by absorbing changes in the attachment position at the engaging part of the locking leg.

It is formed into a substantially rectangular frame shape made of synthetic resin, and has a window hole 22 in the center of the front surface into which a handle for operating the switch 4 is fitted, and an edge portion that protrudes from the front side toward the back side and joins to the wall surface. 23 is formed. An elastic locking leg 24 is formed protruding from the middle part of the back surface of the plate 21 in correspondence with the position of each locking claw 15 of the mounting frame 1. As shown in FIG. 2, an engaging portion 25 is formed with respect to the locking pawl 15 so that the engaging position can be adjusted. This engaging portion 25 has step portions 26 and 27 formed along the protruding direction of the locking leg 24 so that the locking claw 15 can be engaged with the step portions 26 and 27 .

Next, the operation of this embodiment will be explained.

First of all, as shown in FIG. 1, if the mounting surface of the mounting frame 1 and the plate 21 are the same, and when installing the instrument device in a built-in box (not shown) embedded in the wall surface 31, the mounting surface of the mounting frame 1 is The back surfaces of both ends are joined to the wall surface 31, and screws are screwed into the embedded box through the through holes 11 at the upper and lower parts of the mounting frame 1, and tightened and fixed.

Next, the plate 21 is attached to the attachment frame 1 with one touch. In this case, the plate 21 is attached from the front of the mounting frame 1, and each locking leg 24 protruding from the middle part of the back surface of the plate 21 engages with the locking claw 15 while being elastically displaced toward the outer end. At this time, the step portion 27 on the tip side of the locking leg 24 once engages with the locking pawl 15, but there is still a gap between the edge 23 of the plate 21 and the wall surface 31. Then, by further pressing the plate 21 against the mounting frame 1, the edge 23 of the plate 21 comes into contact with the wall surface 31, and the stepped portion 26 engages with the locking pawl 15.

In this attached state of the plate 21, the gap between the plate 21 and the wall surface 31 is small, and the plate 21 is prevented from shaking.

Furthermore, as shown in FIG. 2, wallpaper 32 is pasted on the wall surface 31, and the embedded box part of this wallpaper 32 is cut, and the mounting frame 1 is directly joined to the wall surface 31, but the plate 21 is When the edge 23 of the plate 21 is joined to the wallpaper 32, the step 27 on the tip side of the locking leg 24 is connected to the locking claw 15.

At this time, as shown in FIG. 4, when the mounting frame 1 and the edge 23 of the plate 21 are joined to the same wall surface 31, the base side of the inclined surface portion 41 of the locking leg 24 is locked. It is pressed into contact with the claw 15 and held in an engaged state. Further, as shown in FIG. 5, when the mounting frame 1 is joined to the wall surface 31 and the edge 23 of the plate 21 is joined to the wallpaper 32,
The tip side of the inclined surface portion 41 of the locking leg 24 is pressed against the locking pawl 15 and is held in an engaged state.

In this attached state of the plate 21, the elasticity of the locking legs 24 allows the plate 21 to be attached to the wall surface 31 or the wallpaper 32.
A biasing force acts in the direction of the plate 21 and the wall surface 31.
There is no gap between the plate 21 and the plate 21, thereby preventing the plate 21 from shaking.

Therefore, in this embodiment as well, FIG.
As shown in FIG. 5, the plate 21 is
Even if the mounting positional relationship of the plate 2 is different, the change in the mounting positional relationship is absorbed by the engagement part 25 of the locking leg 24, and the plate 2
