Description

[Detailed description of the invention] This invention relates to a speaker mounting device that houses the speaker in a cylindrical case and fixes the mounting tool on the outside of the case at an arbitrary angle to the case.The mounting tool is attached to the case with bolts. When fixing,
It is an object of the present invention to provide a speaker mounting device that eliminates misalignment between a screw hole of a tightening member and a bolt insertion hole of a case, and allows easy and accurate angle adjustment of a mounting tool.

As shown in Figure 1, the speaker mounting device is a speaker b attached to a cylindrical case a.
A mounting tool f that screws a tightening member c to the rear end d, aligns the legs e and e of the tightening member along the inside of case a, and fastens it to the outside of case a.
A case in which the leg e of the case a and the tightening member c are tightened with a bolt or nut g has been in practical use for some time. However, this structure has the drawback that alignment of the leg piece e through which the bolt g is inserted and the bolt insertion hole of the case a and the fixture f is troublesome and time-consuming, and it takes time to tighten.
Also, after loosening the bolt to adjust the direction of the speaker and adjusting the case 1 to the required angle, when tightening the bolt, the nut will spin idle and cannot be tightened, so it is necessary to fix the nut to the leg piece e. Become.

This invention is aimed at solving the above-mentioned drawbacks, and an embodiment thereof will be described with reference to the attached drawings from FIG. 2 onwards.

Bolt insertion holes 2, 2 and engagement holes 3, 3 are provided on both sides of a cylindrical case 1 made of synthetic resin or the like, and a metal fastening member 4 has leg pieces 5, 5 formed at both ends along the inside of the case 1. A projecting piece 6 that fits into the engagement hole 3 is formed outwardly by cutting and bending on the leg pieces 5, 5 of the case 1. A screw hole 7 is provided in the leg piece 5 that matches the bolt insertion hole 2, and the free ends of both leg pieces 5, 5 are pressed and bent inward to insert the tightening member 4 into the case 1, and the protrusion piece 6 is engaged. The rear end of the speaker 8, which has been previously housed in the case 1, is fitted into the matching hole 3, the pressure of the leg pieces 5, 5 is released, and the tightening member 4 is fixed in the case 1. The tightening member 4 is screwed 9.

In this state, the screw holes 7 of the leg pieces 5, 5 and the bolt insertion holes 2 of the case 1 are aligned, so insert the headed bolt 12 into the bolt insertion holes 11, 11 provided in the shaped fitting 10. The case 1 is screwed through the bolt insertion hole 2 into the screw hole 7 of the leg piece 5, and the angle between the case 1 and the fixture 10 is adjusted appropriately and tightened and fixed.

In the figure, reference numeral 13 indicates a fixing piece of the lid obtained by bending the end of the leg piece 5, and reference numeral 14 indicates the lid.

As described above, according to this invention, the tightening member 4
The bolt insertion hole 2 of the case 1 and the screw hole 7 of the tightening member 4 match when the protrusion 6 provided in the case 1 is fitted into the engagement hole 3 of the case 1. The bolt 12 can be easily screwed into the screw hole 7 of the tightening member 4 without any trouble, and the tightening work of the fixture 10 can be performed easily and quickly. In addition, since a screw hole 7 is directly cut into the leg piece 5 of the tightening member 4, when loosening or tightening the bolt 12 in order to adjust the angle between the case 1 and the mounting tool 10 on site, it is easy to tighten the bolt 12 like a nut. Since the nut does not turn idly, it can be tightened securely and firmly.

In addition, a nut may be welded to the leg piece 5 for the screw hole 7 of the leg piece 5 in the above embodiment, if necessary.
