Description

[Detailed Description of the Invention] This invention relates to a speaker support for installing a speaker in an embedded manner by opening a mounting hole in the ceiling.

As this type of support device, the Utility Model Publication No. 58-1989, which is related to the applicant's application, is
There is a device described in Japanese Patent No. 19894, which includes a support having a slanted surface at both ends of the upper surface, a flange portion in contact with a vertical surface and a lower surface of the ceiling, and a fixture that is screwed so as to be slidable along the slanted surface. It consists of a fixture and a flange that sandwich and fix the ceiling board, but recent ceiling boards are made of relatively thin materials such as plywood and metal plates, as well as soundproofing,
There are thick ones for heat insulation purposes, and because the difference in thickness between the two is large, it is impossible to make them adaptable to any ceiling, and this idea solves the above problem. The main purpose is

An embodiment of this invention will be described with reference to the attached drawings. A mounting hole 2 of a required diameter is formed in a ceiling plate 1, a support is provided across the mounting hole 2, and the upper half of both legs 4, 4 of a frame 3 is inclined downwardly. Part 5, 5
A long hole 6 for vertical adjustment is bored in this part, and a clamping piece 7 is bent along the lower surface of the ceiling plate 1 at the lower end of both legs 4, 4, and a mounting hole 8 is bored therein. A pair of locking pieces 9 are formed by cutting a portion inward.

A separate fastening piece 12 is superimposed on the inclined part 5 of the support frame 3, and the fastening piece 12 has a screw hole 10 that matches the elongated hole 6, and both sides of the inclined part 5 are held on both sides. A bent edge 11 is formed, and the tightening is performed at a horizontal bending line 13 near the lower end of the piece 12.
form.

In the figure, the bending line 13 is formed by drilling six small holes arranged in the horizontal direction so that the bending can be done along the line connecting the small holes, and the tightening is done from the long hole 6 of the inclined part 5 to the screw hole 10 of the piece 12. Insert butterfly screw 14 into.

In addition, 15 is a reinforcing ridge formed by pressing out a part of the piece 12 for tightening, 16 is a speaker, 17 is a hanging ring formed on the speaker frame, and 18 is a hanging bullet hooked to the hanging ring. Then, the bent portions 19 at both ends are engaged and supported by the hooking pieces 9 of the support frame 3.

Reference numeral 20 denotes a decorative frame that covers the speaker frame and the clamping pieces 7 of the support frame 3 exposed on the ceiling surface.

The present invention is constructed as described above, and the butterfly screw 14 is screwed into the screw hole 10 of the piece 12 through the long hole 6 of the support frame inclined part 5, and is temporarily fixed. Insert the support frame 3 into the hole 2, align the clamping pieces 7 at the lower ends of both legs along the lower surface of the ceiling plate, and adjust the tightening by sliding the pieces 12. By tightening the screw 14, the ceiling board 1 is held between the clamping piece 7 and the lower end of the clamping piece 12.

At this time, tighten the piece 12 with the butterfly screw 14 as shown in Figure 6.
As the lower end is tightened to the inclined part 5, the lower end rotates downward and inward, so it can be firmly fixed by biting into the ceiling board. In contrast to the method of strongly clamping and fixing with butterfly screws, the work is difficult and strong tightening is not easy.
With the present invention, it can be firmly tightened just by tightening the butterfly screw, making the work simple and easy.

Next, if the ceiling board is particularly thick, the lower end of the piece 12 will not be able to completely press the periphery of the ceiling position mounting hole 2, but in this case, the tightener should be tightened closer to the lower end of the piece 12, as shown in Figure 7. Bend using the bending line 13, press the presser piece 12/stitch,
Hold the top surface of the ceiling board with the intervening piece 12' and tighten it with the butterfly screw 14.

In this case as well, the effect of tightening by the presser piece 1z is the same as in the case described above.

When tightening the casing, the bent edges 11 on both sides of the mold not only reinforce the pieces 12, but also tighten with the butterfly screws 14 to prevent rotation of time, and the tightening has the effect of making the work stable and reliable. be.

The bending portion 19 of the bullet 18 connected to the speaker 16 is hooked to the hook 9 of the support frame 3 attached to the ceiling plate as described above, and the speaker is supported in the same manner as in the conventional art.

For tightening, the bending line 13 on the lower surface of the piece 12 is arranged not only by arranging the above-mentioned "/" lines, but also by arranging horizontal long holes, or by arranging the bent edge 11 and reinforcing protrusions as shown in Fig. 8A and B. 15 can be divided into 11.11' and 15, 15' at the part corresponding to the bending line, and the part where the bending line 11.11' and the reinforcing protrusions 15, 15' are missing can be used as the bending line 13. For tightening, the bending line 13 can be formed by carving a concave line on the piece 12 or the like.

As described above, according to the present invention, regardless of the thickness of the ceiling board,
In addition, the butterfly screw allows for firm fixation by simply tightening the piece 12 to the inclined portion 5, which facilitates difficult work toward the ceiling surface, and has the effect of preventing loosening over a long period of time.
