Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a speaker mounting bracket used to prevent deformation of the mounting board or speaker frame due to tightening of mounting screws when mounting the speaker on the mounting board.

Most of the conventional mounting brackets of this type have the shapes as shown in FIGS. 1 and 2, and other conventional mounting brackets are also similar in principle. That is, the front part A and the back part B are formed to have almost the same area, and the front part A has a through hole D through which the mounting screw C is passed.
, and a spiral threaded portion E matching the thread shape of a mounting screw C (generally a tapping screw) is formed on the back surface B at a position corresponding to the through hole D described above. The front part A and the back part B are connected in parallel by a connecting part F, and generally these three parts A, B, and F look like a U-shape, so they are called U-shaped metal fittings. There is. The role of this U-shaped bracket is to clamp the mounting board H to which the speaker G is attached between the front part A and the back part B, and to insert the mounting board H into the mounting hole I drilled in order to pass the mounting screw C through the mounting board H. The role of this is to strengthen the connection part F from becoming weak, and to position the connection part F from the inner diameter part J of the opening formed in the mounting board H, and to position the mounting hole I from the inner diameter part J, so that the mounting screw C is These two functions are to ensure that the threaded portion E of the back surface B is in the position where it passes. In FIG. 2, K is a speaker frame, L is a mounting surface of the frame K, La is a through hole for a mounting screw C formed in the mounting surface L, M is a diaphragm, and N is an edge.

Here, the speaker G is a recessed car stereo speaker, and vertical parts O are formed on both sides of the mounting surface L so that it can be installed in places where the space below is narrow, such as a rear tray. Some devices are configured so that the speaker G can be lifted from the front surface of the mounting board H when the speaker G is mounted. however,
If there is a gap between the mounting surface L, where the head of the mounting screw C is located, and the mounting board H, as in the speaker G with this structure, tightening the mounting screw C will cause
The mounting board H is pushed up to the back side of the mounting surface L, and is deformed together with the front part A and the back part B, which are supposed to be reinforced, so that it becomes weakened and may separate from the mounting board H together with the mounting hardware. or,
The mounting surface L of the speaker frame K may also be deformed, and when the speaker frame K is deformed, there is a drawback that malfunctions of the speaker G, such as bumps and scratches, are likely to occur.

Furthermore, there are other means for attaching the speaker frame to the mounting board, such as that shown in Japanese Utility Model Publication No. 44-31110. The above-mentioned conventional technology connects a front part with a through hole and a back part with a screw hole through a connecting part, extends substantially vertically from one end of the front part, and has a locking groove. It was a mounting bracket with an integrally formed extension part. Then, the mounting hole drilled in the speaker frame and the mounting bracket are integrally fixed with screws. Further, the locking protrusion of the annular cover with the net stretched thereon is fitted into the locking groove of the extension portion to be fixed.

However, in the above-mentioned prior art mounting bracket, the integral extension portion having the locking groove is for locking the cover, not for mounting the speaker frame. Additionally, since the speaker frame is attached directly to the mounting bracket using screws as shown in Figure 2, tightening the mounting screws may deform the speaker frame, front section, and rear section. This has the disadvantage that it can cause problems.

Therefore, the present invention aims to solve the above-mentioned drawbacks, and the front part having a through hole for the mounting screw and the back part having a threaded part into which the screw is screwed are connected in parallel by a connecting part, In the speaker mounting bracket configured to clamp the speaker mounting board between the front part and the back part, the front part has the height to the back of the mounting surface of the speaker frame in the peripheral part corresponding to the connecting part. By integrally forming vertical ribs that have at least the same height and a shape that surrounds the through hole in plan view, the fixing effect is further strengthened without deforming the mounting bracket or the speaker frame. The purpose is to provide mounting hardware for speakers.

Hereinafter, the present invention will be explained based on the embodiments shown in the drawings. Figures 3 and 4 are perspective views showing different embodiments of the mounting bracket according to the present invention, and Figures 5 and 6 are perspective views showing the same mounting bracket. FIG. 7 is a cross-sectional view of a different embodiment showing an example of how the metal fittings are used. In the drawing, the metal fitting main body 1 has a U-shape in which a front part 2 and a back part 3 of the same size are connected in parallel by a connecting part 4, and the distance between the double-sided parts 2 and 3 is equal to the thickness of the mounting board 5. They are set the same.
The front part 2 is formed with a through hole 7 through which the mounting screw 6 passes, and the back part 3 is formed with a threaded part 8 at a position corresponding to the through hole 7 into which the mounting screw (generally a tapping screw) 6 is screwed. ing. Further, an integral vertical rib 9 is formed on the surface of the front part 2 at a peripheral portion corresponding to the connecting part 4 at a height at least equal to or higher than the height to the back surface of the mounting surface 12 of the speaker frame 11. This vertical rib 9 has a shape in plan view of the through hole 7.
The vertical rib 9 is formed in a shape that surrounds the vertical rib 9, so that the vertical rib 9 does not bend even when the mounting screw 6 is tightened. . A cylindrical shape is best for the surrounding shape as it minimizes the deformation of the vertical ribs 9 themselves, but from a practical standpoint of processing accuracy when integrally molding and simplifying the installation process, it is best to use a cylindrical shape as shown in Fig. 3. When the vertical rib 9 is made into a "U" shape to surround the through hole 7 as shown in FIG. The through hole 7 is surrounded by a square triangular U-shape.

The mounting board 5 has an opening for mounting the speaker 10, and 5a is the inner peripheral surface of the opening. Reference numeral 13 designates mounting holes for mounting screws 6 formed in the mounting board 5. In addition, a through hole 14 for the mounting screw 6 is formed in the mounting surface 12 of the speaker frame 11, and upright portions 15 and 16 are provided on the inside and outside of the mounting surface 12, respectively, for holding the mounting surface 12 at a predetermined height. is formed, and the inner upright portion 15 is provided with a stepped portion 15a. 1
7 is a diaphragm, and 18 is an edge.

Next, a speaker 10 using the above-mentioned metal fitting body 1 will be described.
The installation will be explained with reference to FIG.

First, the mounting board 5 is clamped between the front part 2 and the back part 3 of the metal fitting main body 1, and the connecting part 4 is brought into contact with the inner circumferential surface 5a as in the conventional example to position it up to the mounting hole 13. The through hole 7 and threaded portion 8 of the fitting body 1 are made to correspond to the mounting hole 13. Next, the speaker 10 is mounted on the mounting board 5, and set so that the mounting surface 12 of the speaker frame 11 and the inner and outer upright portions 15, 16 fit into the vertical ribs 9 of the metal fitting body 1, and the mounting surface 12 is inserted through the mounting surface 12. The hole 14 is aligned with the through hole 7 of the front part 2. With this, the vertical rib 9
The upper surface of is in contact with the back surface of the mounting surface 12, and the stepped portion 15a
and the lower end of the outer upright portion 16 abut against the front surface of the mounting board 5, respectively.

Therefore, both through-holes 1 on the mounting surface 12 and the front part 2
4, 7 and the mounting hole 13 of the mounting board 5, and screw it into the threaded part 8 of the back part 3 and tighten it, a vertical rib 9 will be formed between the front part 2 and the mounting surface 12. Since the ribs 9 are interposed between the front part 2 and the back part 3, the mounting board 5 is evenly clamped to the mounting board 5, thereby preventing damage to the mounting board 5 and reinforcing the speaker 10. It can be fixed to the mounting board 5.

FIG. 6 shows the state of use when using the metal fitting main body 1 in which the height of the vertical ribs 9 formed on the front part 2 is higher than the height of the mounting surface 12; An elastic body 19 is interposed between the connecting portion 4 side of the speaker frame 11 and the stepped portion 15a of the speaker frame 11, and other points are the same as those shown in FIG.

As mentioned above, the present invention has a through hole 7 for the mounting screw 6.
A front part 2 having a screw part 2 and a rear part 3 having a screw part 8 to which the screw is screwed are connected in parallel by a connecting part 4, and a speaker mounting board 5 is clamped between the front part 2 and the rear part 3. In the speaker mounting bracket configured as shown in FIG.
A vertical rib 9 having a height at least the same as the height to the back surface of the mounting surface 12 of the speaker frame 11 and having a shape that surrounds the through hole 7 in plan view is integrally formed in a peripheral portion corresponding to the vertical rib 9. This is what I did.

Therefore, even when the mounting screws 6 are tightened, the fixing effect can be further strengthened without deforming the mounting bracket 4 or the speaker frame 11. Furthermore, the mounting bracket can be easily molded in one piece, and the installation process is also simple. Become something.
