After assembling the information panel, the functional unit is attached to the mounting bracket using screws or the like.

The conventional information board has a problem in that it takes time to assemble. This is because screwing operations have become very common, such as screwing the mounting bracket to the box and then screwing the frame to the mounting bracket.

[Purpose of invention]

This idea was made in view of these circumstances, and the purpose is to provide an information board that can be assembled in a short time.

[Disclosure of invention]

In order to achieve the above objectives, the inventors conducted repeated research and found that it was possible to fix the functional unit directly to the frame, and to fix the frame directly to the opening of the box body. I discovered this and completed this idea.

That is, this invention is an information board that is equipped with a box body in which a functional unit is housed and a frame that is attached to the front side of the box body. , each of which has a second protruding piece on the back side for attachment to the box body, and the first protruding piece has a gap in front of the operation point for attaching the second protruding piece to the box body. The functional unit is fixed to the frame using the first projecting piece, and the frame is directly fixed to the opening of the box using the second projecting piece. The summary of the information board is as follows. Hereinafter, this invention will be explained in detail based on drawings showing embodiments.

As shown in FIG. 2, the information board according to this invention includes a box 6 embedded in a wall 1 and a frame 7 attached to the front of the box 6.
The box body 6 that houses the functional unit has screw holes 6a for attaching a frame 7 at the periphery of the opening.
The frame 7 is made, for example, by combining four frame members made by extruding a material such as aluminum, and has three first protruding pieces 8 for attaching a functional unit on the inside of both vertical parts. and a second one for attachment to the box body 6 at the back of the protruding piece 8.
One protruding piece 9 (only one is visible in the figure) is provided. In this example,
As shown in FIG. 3, the vertical portion of the frame 7 has a structure in which one end of an inverted U-shaped portion 7b is connected to the middle of the vertical bar of the horizontal L-shaped portion 7a. The tip of the vertical bar of the horizontal L-shaped portion 7a becomes the second protruding piece 9, and the first protruding piece 8 is provided on the side of the inverted U-shaped portion 7b. This is because such a structure has the effect of facilitating molding. As shown in FIGS. 2 and 3, the first protruding piece 8 is provided with a screw hole 8a for fixing the functional unit. In the second protruding piece 9, at a position facing the gap between the adjacent first protruding pieces 8, 8,
A screw insertion hole 9a for attachment to the box body 6 is provided. Insertion of a screw into the screw insertion hole 9a and insertion of a screwdriver into the screw can be performed through the gap between the adjacent projecting pieces 8, 8.

Fit the frame 7 to the front surface of the box body 6, insert the screws 5c into the screw insertion holes 9a of the second protruding piece 9 and the screw holes 6a of the box body 6, as shown in FIG.
A frame 7 is fixed to the front opening of the box body 6. The information board is assembled in this way.

The functional units 10a and 10b have screw insertion holes provided therein and a screw hole 8a of the first protruding piece 8.
It can be directly attached to the frame 7 by inserting screws 8d into the frame 7 (see FIGS. 3 and 4). In this way, in the information panel according to this invention, the functional unit is directly fixed to the frame, and the frame is directly fixed to the opening of the box body, so there is no need for mounting brackets like the following. There are fewer parts. Therefore, since the number of screws to be fixed is reduced, assembly can be completed in a short time, making the assembly work easier.

Note that the number and position of the first protruding pieces and the second protruding pieces are not limited to those in the embodiment, and can be appropriately determined as necessary.

(Effect of the invention) In the information board according to this invention, the frame is provided with the first and second protruding pieces as described above, the functional unit is directly fixed to the frame, and the frame is directly fixed to the opening of the box body. Since it is designed to be fixed, assembly time is extremely short.

In particular, on the inside of the frame, the first protruding piece is provided on the front side close to the mounting surface on the back of the functional unit, and the second protruding piece is provided on the back side near the mounting surface of the box. Easy to perform installation work such as locking operation. In other words, if the functional unit and the box body are attached to the same protruding piece, for example, if the protruding piece is located close to the box body, screws should be attached to the box body with the protruding piece in contact. Since it is possible to perform installation work such as fixing, screwing operations are easy and sufficient installation strength can be ensured, but due to the distance to the functional unit installed on the front of the frame, it is necessary to use long screws to install the functional unit. In addition, problems arise such as the rear surface of the functional unit cannot be brought into contact with the protruding piece, making the installation unstable. Conversely, the same problem naturally occurs when the protruding piece is located only at a position close to the functional unit. In this regard, in this invention, since the protruding pieces are provided separately at positions close to each of the functional unit and the box body, the installation work for both becomes easy and sufficient installation strength can be ensured.

In addition, in order to attach the protruding piece and the box body in close contact with each other, the protruding piece may be slightly deformed by tightening the screws and attached tightly to the surface of the box body, but after that, the same protruding piece When attempting to attach the functional unit to the deformed protruding piece, the back surface of the functional unit cannot be brought into close contact with the deformed protruding piece. However, in this invention, even if the second protruding piece is deformed during the installation work on the box, the first protruding piece is not deformed at all, so the back of the functional unit is attached tightly. If necessary, the first protruding piece can be deformed to some extent by tightening the screw and brought into close contact with the back surface of the functional unit. That is, since the functional unit and the box body are each provided with a dedicated protruding piece, the functional unit and the frame, and the frame and the box body can both be attached accurately and firmly.

Furthermore, the heads of the mounting screws used to attach the second protruding piece to the box fit between the second protruding piece and the first protruding piece, and do not protrude further forward than the first protruding piece. . This is because if you try to attach the functional unit to the front of the protruding piece that has been attached to the box, the heads of the box attachment screws that protrude from the surface of the protruding piece will get in the way, and the functional unit will not fit properly. However, according to this invention, since the surface of the first protruding piece is always flat, the back side of the functional unit can be brought into tight contact with the surface of the first protruding piece, and it can be accurately pressed. And it can be firmly attached.

However, if the first protruding piece and the second protruding piece are provided separately in the front and rear, when trying to insert a screw or the like into the second protruding piece and screwing it into the box, the first protruding piece The protruding piece interferes with work such as screwing. Therefore, in this invention, a gap is provided in a part of the first protruding piece, and from this gap,
By setting the mounting screws on the box body and operating tools such as a screwdriver, the work of attaching it to the box body can be carried out without any problems.
