Description

[Detailed description of the invention]

[0001]

This invention is used to attach a speaker box for BGM or an announcement for use in a place where people gather, such as a living room or a lobby, to a wall surface of a flat portion of a room, and to be detachable. The present invention relates to a speaker box mounting device that can be detached freely and easily.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, a speaker box mounting device of this type is configured such that a nail (31) formed with a hanging portion (metal) is fastened to a wall surface (11) by tightening or fastening. It is fixed by driving, and is suspended by being fitted into a hole of a suspension fitting (32) on the speaker box side attached to the speaker box (12).

[0003]

Therefore, in the conventional suspension mounting apparatus for a speaker box (12) of this type, when the speaker box (12) is mounted on a flat wall surface (11), the suspension fitting (31) on the speaker box side is used. ) Is the speaker box (12)
It is difficult to fit the holes of the speaker box side bracket (32) into the hanging bracket (31) on the wall (11) side because it is mounted on the back side of the The disadvantage is that the speaker box is not stable even after installation. Also when removing,
Since the position of the hanging bracket (31) is not visible, it has a drawback that it takes time to remove it.

In particular, when the shape of the speaker box is a corner shape in which the rear surface is narrowed, the speaker box is
Poor stability, difficult to attach and remove. Also, compared to the case where one set of such corner-shaped speaker boxes is attached, two sets are arranged side by side on a flat wall back to back, especially by utilizing the acoustic reflection of the wall, and each is driven by parallel driving. In the case of a double speaker box which emits sound uniformly to every corner of a room with a low acoustic radiation output, high efficiency, and broad radiation directivity, there is a remarkable difficulty in installation work. To put it bluntly, it was not an exaggeration to say that there was no peaker mounting device that could be easily attached to and detached from the wall.

In order to solve the problems of the conventional speaker box mounting device, the present invention combines the structure of the mounting brackets on both the flat wall side and the speaker box side. By devising a structure that is easy to put on and take off, not only can one set of speaker boxes be mounted on a flat wall surface, but also two sets can be mounted back to back and one set can be mounted on a corner wall surface. Free, easy and easy installation, suppressing the rise in cost,
An object of the present invention is to provide a speaker box mounting device which can be detached and which can significantly reduce and shorten the time and effort required for attachment and detachment.

[0006]

The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 6 corresponding to the embodiment. The present invention folds at right angles to each other into an L shape. Steps (2) and (2) are provided on both side edges of one bent piece (1a) of a bent wide band-shaped metal plate (1) to form rails (2a) and (2a) in the longitudinal direction. At the same time, the bent spring plate material (3) having the hook portion (3a) formed at the tip is directed outward, and the base portion (3b) is fixed by welding or rivets (3d). The mounting holes (4a), (4a), (4b), and (4b) are drilled, and the other bending piece (1b) is formed on both side edges of the bending piece (1b) in the same manner as the bending piece (1a). Steps (2 '), (2') are provided, and rails are
(2a ') and (2a') are formed, and a bent spring plate material (3 ') having the same shape as the spring plate material (3) on its inner surface and having a hook portion (3a') formed at the tip is formed on the outer surface. As shown in FIG. 4, the mounting bracket (8), which is formed by fixing the base (3b ′) to the base by welding or rivets (3d ′), is attached to the mounting holes (4a), (4b ) Is attached to the wall surface (11) side by set screws (15) and (15). (Note: In this specification, a speaker box refers to a corner-shaped speaker box in which a speaker is housed and wired and wiring is completed, and a speaker case refers to a corner-shaped speaker case body.)

Next, on the speaker box (10) side, a base (6e) is provided on one back surface (6b) of the speaker case (6) along the side of the recess (6d) formed. Then, a U-shaped insertion fitting (5) is placed thereon, and is fixed through the mounting holes (5b) and (5b) through set screws (16) and (16). 11) forming a receiving portion (5a) for fitting and inserting the rails (2a) and (2a ') of the mounting bracket (8) on the side, and a spring plate material (3) of the mounting bracket (8);
At the position corresponding to the concave portion (6d) of the speaker case (6) corresponding to (3 '), a convex portion (7) for engaging with the hook portions (3a) and (3a') is formed,
With this configuration, the rails (2a), (2
a ') into the receiving part (5a) formed in the speaker case (6) in the direction of the arrow, and insert the speaker box (10) and the wall (11).
This is a speaker box mounting device obtained by connecting a mounting bracket (8) mounted on a speaker box.

[0008]

[Function] The present invention is based on such a conventional mounting wall (1
Since the structure of the mounting bracket (8) and the receiving part (5a) on both the 1) side and the speaker box (10) side is modified as described above, first, when mounting, the mounting bracket (8) on the wall (11) using the mounting holes (4a) and (4b) to set screws (15),
(15), and then fix it in place.Next, fix the fitting (5) to the base (6e) on the back (6b) of the speaker case (6) with a set screw (16), etc. Receiving part (5a)
Into the mounting bracket (8) attached to the wall surface (11) in the direction of the arrow, and the projection (7) formed on the speaker case (6).
The hook (3) at the tip of the leaf springs (3) and (3 ') of the mounting bracket (8)
By simply pushing in until a) and (3a ') are fitted, the speaker boxes (10) and (10) can be automatically and firmly attached and fixed to the wall surface (11).

[0009] When removing, by the reverse operation of the above,
The speaker box (10) can be easily detached by sliding the speaker box (10) in the direction opposite to the arrow to release the hooks (3a), (3a ') and the projection (7) and pull out.
