Description

[Detailed Description of the Invention] This invention relates to a support for attaching a speaker to a wall surface or the like, and particularly to a structure of a support that allows the mounting angle of the speaker to be made variable.

Conventionally, many speaker supports that allow you to change the mounting angle of the speaker combine two adjustment mechanisms, horizontal and vertical, to change the mounting direction of the speaker three-dimensionally. Usually, the mounting fixture used for this purpose is of a different structure, and it takes time and effort to operate the adjustment mechanisms in two places, which is extremely troublesome and has the drawbacks of high cost due to the large number of parts. .

The purpose of this invention is to engage a U-shaped fixing member with a position adjusting member that is approximately cylindrical and has a horizontal slit on its circumferential surface, and to insert the fixing member into the slit from the outside of the fixing member. By passing the bolt through the cylindrical body within the position adjustment member and fixing it, it is possible to adjust the speaker direction over a wide range of angles, and
It is an object of the present invention to provide a speaker support that can reliably support a speaker with sufficient strength.

An example of this invention will be explained in detail below based on the drawings.

Reference numeral 1 denotes a mounting piece having a mounting hole 2 to be fixed to a back plate of a speaker box, etc., and a substantially cylindrical position adjustment member 4 integrally attached to this through a connecting member 3.

The position adjustment member 4 has a cylindrical opening with both openings facing up and down, and has a slit 5 in the horizontal direction on its circumferential surface.

6 is a U-shaped fixing member that is fixed to a mounting surface such as a wall or ceiling through a mounting hole 7 in the center, and has a bolt hole 8 in the center of both ends.
, 8 are drilled.

Reference numeral 9 denotes a bolt, which is inserted through the slit 5 of the position adjustment member 4 from one bolt hole of the U-shaped fixing member 6, through which the cylindrical body 10 fitted into the member is inserted, and further into the slit 5.
And the bolt hole 8 is tightened and fixed by a wing nut 11.

The width of both ends of the U-shaped fixing member 6 is such that the cylindrical body 10 into which the cylindrical part of the position adjustment member 4 is fitted has approximately the same length as the inner diameter of the cylindrical part, and the outer diameter is the width of the slit 5. The inner diameter is larger than the thread diameter of the bolt 9.

Furthermore, if the speaker to be mounted is pillar-shaped and elongated, and if the angle of the speaker is changed in the vertical direction, one end will hit the wall of the mounting surface and the speaker cannot be moved any further, an extendable tool 12 as shown in FIG. 2 is used.

That is, this extendable tool 12 has two U-shaped rods 13 a
, 13b are placed one on top of the other, and the fixing bolts and nuts 15 are adjusted and fixed in the long holes 14 formed in the outer U-shaped member 13b.

Furthermore, one side is provided with a mounting hole 16 to be fixed to the mounting surface, and the other side is provided with a hole 7 that communicates with and connects with the mounting hole 7 of the fixing member 6.

In the speaker support of the present invention having the above structure, in order to change the direction of the speaker, the wing nut 11 is slightly loosened, the angle is set, and then the wing nut 11 is tightened again.

That is, at this time, the cylindrical body 10 always passes through the center of the position adjustment member 4 and is at the diameter position of its inner diameter, so that even if the wing nut 11 is strongly tightened, the cylindrical position adjustment member 4 will not be distorted, and the slit will not be distorted. 5 is fixed at two locations in the diametrical direction together with the U-shaped fixing member 6, with its position being reliably regulated.

Therefore, in the present invention, the strength of the direction adjustment mechanism, which is easily deformed due to lack of strength as seen in the past, is reinforced, and at the same time it also serves as a support, and the cylindrical position adjustment member has a cylindrical shape. It has sufficient mechanical strength as a movable connecting means, prevents deformation, cracking, and breakage around the slit, and allows for wide-angle directional adjustment with a single tightening operation using a single bolt. This has the effect of ensuring speaker support.
