Description

[Detailed description of the invention] The present invention relates to a structure for mounting a speaker on a wall, and it is possible to attach the metal fitting fixed to the speaker to the metal fitting fixed to the wall very easily and with great strength. An object of the present invention is to provide a wall-mounting structure for a speaker, which allows the mounting posture of the speaker to be easily changed.

For example, to fix a speaker to a wall, a speaker mounting structure is sometimes used in which mounting fittings are fixed to the wall and the speaker, respectively, and both fittings are tightened and fixed using bolts and nuts.

However, in this type of conventional speaker mounting structure, bolt insertion holes must be drilled at predetermined positions in each of the wall fixing bracket and the speaker fixing bracket, and the bolts must be inserted with both bolt insertion holes aligned. It is very troublesome to align the two metal fittings and insert the bolt, and the speaker has to be supported by hand until the bolt is inserted, which causes fatigue in the arms.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

Fig. 1 is a side view of an embodiment of a speaker to which the speaker wall mounting structure of the present invention is applied, and Figs.
A perspective view and an exploded perspective view of the main part of the figure are shown.

In FIG. 1, a speaker 1 is mounted on a wall 2 of a conference room or a hallway, for example, so as to be inclined downward at an angle θ.

Wall fixing fittings 3 and 4 are fixed to the wall surface 2 at two locations, a fitting 5 fixed to the bottom of the speaker 1 is fixed to the fitting 4, and a fitting 6 fixed to the top of the speaker 1 is connected to the fitting 7 via a connecting fitting 7. 6, the speaker 1 is attached to the wall surface 2.

The lower metal fitting 4 fixed to the wall surface 2 has a U-shape like the upper metal fitting 3, and as shown in FIGS. 2 and 3, it has a plate-shaped base 40 that is fixed in contact with the wall surface 2, It is generally composed of a pair of plate-shaped legs 41 and 42 which are bent at both ends of the base 40 and face each other with a predetermined distance apart.

Screw holes 41a and 42a are formed approximately in the center of the leg portions 41 and 42, and a flat washer 43, a chrysanthemum washer 44, a locking member 45, a sponge washer 46, etc. are inserted into these holes 41a and 42a. The bolt 47 that has been removed is temporarily tightened.

The locking member 45 is for fixing the metal fitting 5 around the bolt 47 when the metal fitting 5 is assembled to the metal fitting 4, and has a shape in which claws 45 b and 45 C are bent at both ends of a rectangular plate material. It is.

The speaker fixing bracket 5 fixed to the bottom of the speaker 1 is
Like the metal fitting 6 fixed to the top surface of the speaker 1, it has a U-shape.

The speaker fixing bracket 5 has a plate-shaped base 50 that is fixed by matching with the bottom surface of the speaker 1, and a space slightly larger than the distance between the legs 41 and 42 of the wall fixing bracket 4 at both ends of the base 50. A pair of plate-shaped legs 51 bent at a distance.
It is roughly composed of 52.

A U-shaped notch groove 51a is provided at the tip end edge of the leg portion 51.52.
52a, and rectangular locking holes 51b, 51C are formed on both sides of the cutout grooves 51a, 52a.
and 52b, 52C are perforations.

The notch grooves 51a and 52a are sized to engage with the threaded portion of the bolt 47, and the distance between the locking holes 51b and 51C and the distance between the locking holes 52b and 52C are such that the bolt 47 can be fitted into the grooves. The locking claw 45b of the locking member 45.

The spacing is approximately the same as the spacing between 45C and 45C.

Next, the operation of attaching the speaker 1 to the wall surface 2 will be explained.

First, one end of the connecting fitting 7 is temporarily fixed to the upper wall fixing fitting 3 by bolting.

Further, a locking member 45 and necessary washers 43, 44, 46 are temporarily fixed with bolts 47 to the screw holes 41a, 42a of the respective legs 41, 42 of the lower wall fixture 4.

Then, the sponge washer 46 is pressed against the head side of the bolt 47, and the leg portion 51 of the metal fitting 5 is placed between the metal fitting 4 and the locking member 45.
Leave a gap slightly larger than the plate thickness of ゜52.

In this way, the lower wall fixture 4 with the necessary parts temporarily assembled is fixed to a predetermined position on the wall surface 2 together with the upper wall fixture 3 using predetermined anchor bolts (not shown).

Next, bolt insertion holes are formed in the bottom and top surfaces of the speaker 1, respectively, and the metal fittings 5 and 6 are bolted and fixed, respectively.

Next, the speaker 1 is lifted and the metal fitting 5 is assembled to the metal fitting 4 so that the legs 51 and 52 of the metal fitting 5 on the bottom of the speaker 1 straddle the legs 41 and 42 of the metal fitting 4.

At this time, the notch grooves 51a and 52a are engaged with the corresponding threaded portions of the bolts 47, respectively.

As a result, the weight of the speaker 1 is supported by the metal fitting 4 via the bolt 47, and the subsequent work can be carried out easily.

Next, the upper part of the speaker 1 is held, and the metal fitting 6 on the upper surface side is temporarily fixed to the other end side of the connecting metal fitting 7 by tightening bolts.

Note that the bolt insertion hole on the other end side of the connecting fitting 7 is a long hole 7a.
By changing the bolt insertion point,
The tilt of the speaker 1 can be changed at will.

After the speaker 1 is temporarily held in this way, the inclination of the speaker 1 is adjusted to a desired angle, and then all the temporarily fastened bolts including the bolt 47 are tightened.

In that case, for the bolt 47, the locking hole 51 of the metal fitting 5
The locking claws 45 b and 45 C of the locking member 45 are inserted and locked into the locking members 45 b and 51 C and 52 b and 52 C, and then tightened.

Therefore, the locking member 45 is fixed in the locked state as the bolt 47 is tightened.

As a result, the metal fitting 5 is firmly fixed to the metal fitting 4 in a state where it is prevented from rotating around the axis of the bolt 47.

In addition, since the locking member 45 is pressed into contact with the legs 41 and 42 of the metal fitting 4 while holding the sponge washer 46 between them, the locking member 45 may have poor contact due to the unevenness of the metal surface. This ensures a secure fixation.

In this way, the metal fitting 5 is temporarily assembled to the metal fitting 4 by simply engaging the notched grooves 51a and 52a with the temporarily fastened bolts 47. Compared to a structure in which the metal fittings 4 and 5 are inserted through each other, the fittings 4 and 5 can be aligned easily and easily, and therefore the assembly work is extremely simple.

Furthermore, the metal fittings 4 and 5 are fixed using the locking claws 45 of the locking member 45.
b, 45C to the locking holes 51b, 51c and 52
b, 52C, the fixed state is stronger compared to the case where bolts and nuts are simply tightened from both sides, and the fixation is particularly strong against external vibrations applied to the speaker 1 or moments around the bolt 47. It is strong against loads and can maintain its installation without looseness for a long period of time.

In the above embodiments, the upper surface of the speaker 1 is not limited to the metal fittings 3, 6.7, but may also be supported by a string-like body suspended from the ceiling, or The upper part of the speaker 1 may be supported from the front side by a support member, and in either case, the speaker 1
The speaker 1 is fixed without play due to the strong connection of the metal fitting 5 on the bottom surface side to the metal fitting 4.

As mentioned above, the wall mounting structure of the speaker according to the present invention is
Straddle the legs of the speaker fixing bracket fixed to the speaker over the legs of the wall fixing bracket fixed to the wall, and at that time, engage the notched grooves in the legs of the speaker fixing bracket with the bolts temporarily fastened to the wall fixing bracket. Because of this structure, the speaker fixing bracket can be easily temporarily assembled to the wall fixing bracket, and since the weight of the speaker is supported by the wall fixing bracket in this state, the speaker can be easily supported by hand. This makes it extremely easy to tighten the bolts, and when tightening the bolts,
Since the bolt is fitted in advance and the claw of the locking member is locked into the locking hole of the speaker fixing bracket and tightened, the speaker fixing bracket can be securely fixed to the wall fixture without play. In addition, the installation posture of the speaker fixing bracket relative to the wall fixing bracket can be easily adjusted by slightly loosening the bolt, so it has the advantage of being applicable to various wall surfaces.
