[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling speaker mount used for mounting a speaker on the back side of a ceiling.

[0002]

2. Description of the Related Art In recent years, a ceiling of a building or the like may be formed by combining a plurality of ceiling panels 2 as shown in FIG. On the back surface side of these ceiling panels 2, a large number of support fittings 4 as shown in FIG. 5 may be arranged for reinforcement in order to attach the lighting fixture 6.

When a speaker is mounted in the ceiling having such a structure and a ceiling hole 8 is made between the lighting fixtures 6 in the ceiling panel 2, it is supported at the position of the ceiling hole 8 as shown in FIG. There may be a metal fitting 4. In such a case, as shown in FIG. 6, in order to avoid the support fitting 4, the speaker 10 is provided so as to be displaced from the ceiling hole 8. In addition, 12 is a ceiling speaker mounting tool on which the speaker 10 is mounted. Alternatively, the support fitting 4
It has been performed that cutting is performed at the position of the ceiling hole 8, the speaker 10 is attached to the position of the ceiling hole 8, and instead, the ceiling is reinforced at another place.

[0004]

However, when the mounting position of the speaker 10 is shifted as shown in FIG.
There is a problem that a part of the sound is hidden by the ceiling panel 2, the acoustic characteristics of the speaker are deteriorated, and the loudspeaking cannot be performed well. A speaker panel (not shown) is usually attached to the ceiling hole 8, but in particular, the speaker panel is attached by pulling the speaker panel with an extension spring (not shown) provided on the ceiling speaker attachment 12 side. However, there is also a problem that the speaker panel cannot be attached to the model.

Also, the support fitting 4 is cut to remove the speaker 1.
Reinforcing the ceiling at another place after attaching 0 has been a troublesome work, and there has been a problem that the installation efficiency of the speaker is lowered.

[0006] It is an object of the present invention to provide a ceiling speaker mounting tool capable of efficiently mounting a speaker even when there is a support fitting on the back side of the ceiling where the speaker is mounted.

[0007]

In order to achieve the above object, the first aspect of the present invention forms the ceiling by surrounding the ceiling hole formed in the ceiling on the back surface side of the ceiling. A loudspeaker having a height dimension larger than the height of the supporting bracket of the ceiling plate, which is disposed on the back surface of the ceiling, and a loudspeaker that is coupled to the circumferential wall and that expands toward the ceiling hole. And a top wall for attaching, and means for removing any position of the peripheral wall over the height of the support fitting and the width of the support fitting or more. It is a thing.

The second aspect of the present invention is the same as the first aspect of the present invention.
The removable means has a plurality of slits formed downward from a position corresponding to at least the upper end of the support fitting on the peripheral wall, and these slits have a width dimension of the support fitting in the circumferential direction of the peripheral wall. It is provided at a narrower interval than that. A third aspect of the present invention is the second aspect of the invention, wherein the lower end of each slit is open at the lower end of the peripheral wall.

[0009]

According to the first aspect of the present invention, when the ceiling hole is formed in the ceiling and the supporting metal fitting is located at the position of the ceiling hole, the means for removing the peripheral wall of the ceiling speaker fixture according to the first aspect of the present invention. By this, the place where the supporting metal fitting passes on the peripheral wall is removed by the height dimension and the width dimension or more of the supporting metal fitting, and the ceiling speaker fixture can be arranged on the ceiling hole. And
Attach the speaker to the top wall.

According to the second aspect of the present invention, since the removable means is formed by the slits, it suffices to remove the peripheral wall so as to connect the slits, which facilitates the work. Further, according to the third aspect of the present invention, since the lower end of each slit is open, the work of opening the lower end of the slit is unnecessary, and the work is further facilitated.

[0011]

EXAMPLE A ceiling speaker fixture 14 of this example is used when a ceiling bracket 16 has a circular ceiling hole 18 as in FIG. 5, and a supporting metal fitting 20 is present at that location. It is a thing.

The ceiling speaker mount 14 has a relatively thin thickness so that it can be cut with a tool such as a nipper, and is made of metal or synthetic resin, and as shown in FIG. As a peripheral wall having a square upper wall 22 and extending downward from the periphery thereof, for example, a side wall 24,
It has 26, 28 and 30. The width of the upper wall 16 is larger than the width of the support fitting 20 and the diameter of the ceiling hole 18, and a circular through hole 32 is formed in this. A speaker 38 is arranged on the upper wall 16 so as to be able to make a loud sound through the through hole 32.

Each of the side walls 24, 26, 28, 30 has a height dimension slightly larger than that of the support fitting 20, and these side walls 24, 26, 28, 30 have a height in the thickness direction. Slits 34 penetrating through are formed respectively. Each slit 34 is formed downward from a position above the upper end of the support fitting 20, for example, from the upper ends of the side walls 24, 26, 28, 30.
The lower end of 4 is located slightly above the lower ends of the side walls 24, 26, 28, 30 and can be easily cut from the lower ends of the side walls 24, 26, 28, 30 to the slits 34 with a tool such as a nipper. It is the distance that can cut to the lower end.

Further, each slit 34 has a side wall 24, 2
They are arranged at predetermined intervals along the circumferential direction of 6, 28, 30 and, for example, along the edge direction of the upper wall 22. These intervals are also shorter than the widthwise dimension of the support fitting 20, for example, an interval at which the upper ends of the slits 34 can be easily cut with a tool such as a nipper.

The ceiling speaker mount 14 having such a structure
When a ceiling hole 18 is formed in the ceiling panel 16 and the support fitting 20 is present at that location, the ceiling hole 18
Place the ceiling speaker fixture 14 on top of the support bracket 2
The part of the side wall where 0 contacts is removed using the slit 34.

For example, assuming that the support metal fittings 20 are in contact with substantially the central portions of the side walls 24, 28 facing each other, first, the support metal fittings 20 are located at the central portions of the side wall 24 at a distance greater than the width dimension of the support metal fitting 20. The lower end of the one slit 34 and the lower end of the side wall 24 are shown in FIG.
Cut as shown in. Then, the upper ends of the two slits 34 thus cut are cut as indicated by a chain line c. As a result, an opening as shown by reference numeral 36 in FIG. 1B is formed in the side wall 24. Similarly, the opening 36 is formed in the side wall 28.

Then, as shown in FIG. 1B, the ceiling hole 1 is formed so that the support fitting 20 passes between the openings 36.
The ceiling speaker fixture 14 is placed on the upper part 8. Then, the speaker 38 is arranged on the upper wall 22 of the ceiling speaker fixture 14.

The upper wall 22 of the ceiling speaker fixture 14
The upper ends of the tension springs 40, 40 are previously coupled to the inner surface of the ceiling speaker 18, and the ceiling speaker mount 14 is mounted on the ceiling hole 18.
When the is arranged, the lower ends of the tension springs 40, 40 are
It is pulled out from the ceiling hole 18. Then, while pulling these tension springs 40, 40 further downward,
The lower ends of the tension springs 40, 40 are engaged with the speaker panel 42. Next, when the tensioned state of the tension springs 40, 40 is released, the tension springs 40, 40 are compressed, and the speaker panel 42 is attached to the ceiling hole 18 by the spring force at that time.

Instead of forming a plurality of slits 34,
It is also conceivable to form the opening 36 as described above in the center of the side walls 24 and 28 in advance. However, in this case, for example, when the ceiling hole 18 is formed, if the supporting metal fitting 20 is not located at the center of the ceiling hole 18 but at a position biased to one side as shown in FIG. 2, the supporting metal fitting 20 does not pass between the openings 36. . On the other hand, in the case where a plurality of slits 34 are provided as in the ceiling speaker fixture 14, it can be dealt with by changing the position of the slit 34 to be cut as shown in FIG.

Instead of forming a plurality of slits 34, it is also conceivable to remove the side walls 24 and 28 in advance to form a ceiling speaker mount having an inverted concave side surface. In this case, the problem does not occur even if the support fitting 20 is biased to one side of the ceiling hole 18, but the side wall 26, 30 is mounted on both sides of the support fitting 20 so that the inverted concave ceiling speaker is mounted. You have to place the ingredients. That is, when arranging, the directionality must be considered, and the mounting work is troublesome. On the other hand, in this ceiling speaker fixture 14,
Since the slits 34 are formed in all of the side walls 24, 26, 28, 30, it is possible to cut the slits 34 in any of the side walls, and it is not necessary to consider the directionality, and the work becomes easy.

In the case of an inverted concave ceiling speaker mounting tool, since the speaker 38 is supported only by the two side walls 26, 30, the side walls 26, 30 must be thickened.
Sufficient strength to support the speaker 38 cannot be obtained, and its weight becomes heavy. On the other hand, in the case of this ceiling speaker fixture 14, the four side walls 24, 26, 28,
Since it has 30, each side wall 24, 26, 28, 30
Even if it is not thick, it has sufficient strength to support the speaker 38, and since it is provided with a large number of slits 34, it can be made lightweight.

FIG. 3 shows another embodiment of the ceiling speaker fixture, in which the slit 34a formed in each side wall 24, 26, 28, 30 extends to the lower end of each side wall 24, 26, 28, 30. It is open. Since the lower end of the slit 34 is opened at the lower ends of the side walls 24, 26, 28, 30 in this way, the cutting work of the slit 34a may be performed only at the upper end of each slit 34a as indicated by the symbol d. Work becomes easy. The parts corresponding to the respective constituent elements shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted.

In the above-described embodiment, the ceiling speaker mount has a rectangular upper wall 22 and side walls 24, 26, 28, 30.
Although the flat rectangular parallelepiped shape having the above is shown, the shape of the upper wall can be arbitrary.

In the above embodiment, the slits 34,
34a was made to be able to remove arbitrary positions of the side walls 24, 26, 28, 30. However, instead of the slits 34, 34a, along the height direction of the side walls 24, 26, 28, 30 and the edge direction of the upper wall 22. Thus, a large number of small holes may be formed at intervals narrower than the width of the support fitting, for example, at intervals that can be cut with a tool such as a nipper.

Further, in the above embodiment, the two tension springs 40 are used to mount the speaker panel 42 in the ceiling hole 18, but one tension spring is used on the upper wall 22 of the ceiling speaker mount 14. Alternatively, the both ends of the speaker panel may be pulled out downward from the small holes formed in the upper wall 22 and pulled so as to pass through the ceiling hole 18, and the speaker panels may be coupled to the both ends.

[0026]

As described above, according to the first aspect of the present invention, by the means for removing the peripheral wall formed on the peripheral wall,
Since the place where the supporting metal fitting passes on the peripheral wall can be removed more than the height dimension and the width dimension of the supporting metal fitting, even when the ceiling metal fitting is formed at the place of the ceiling hole when the ceiling hole is formed in the ceiling. The ceiling speaker fixture can be placed on the ceiling hole. Therefore, it is not necessary to dispose the speaker off the ceiling hole, the acoustic characteristics of the speaker are not deteriorated, and the speaker panel can be attached to the ceiling hole by a tension spring provided on the ceiling speaker attachment side. Further, since the work of cutting the support fittings is unnecessary, the work of mounting the speaker becomes easy.

According to the second aspect of the invention, the removable means has a plurality of slits formed downward from the upper end of the peripheral wall, and these slits have a width dimension of the support fitting in the circumferential direction of the peripheral wall. Since the slits are provided at a narrower interval than that, it is only necessary to remove the peripheral wall so as to connect the slits, which facilitates the work.

According to the third aspect of the invention, since the lower end of each slit is opened at the lower end of the peripheral wall, the work of cutting the peripheral wall to open the lower end of the slit is unnecessary, and further work is required. It will be easier.
