Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a mounting tool for rotatably attaching a subordinate object to a main object, for example, a television in which the television main body and the speaker part are separate. This invention relates to a mounting tool for attaching a TV main body and a speaker unit.

[Conventional technology]

Conventionally, hinges have been used as attachments for rotatably attaching a subordinate item to a main body, but for example, hinges are used to attach the TV body and speaker unit of a TV where the TV body and speaker unit are separate. There was no such thing as a fitting.

[The problem that the idea aims to solve]

However, in conventional audio products such as televisions, the TV main body and the speaker section were integrated, but the base to support the TV needed to be the same size as the TV main body and the speaker section, and the sound In terms of effectiveness, it is necessary to change the direction of the speaker section depending on the size of the room where the TV is installed and the number of people in the room, so it has become popular to have the TV body and the speaker section separate. However, in the case of separate units, the base that supports the TV itself is smaller, and although the direction of the speaker unit can be changed, it requires a new location for the speaker unit, making the living space narrower. Summer. However, in order to improve the acoustic effect, it is unavoidable, so it was considered to hinge the TV body and the speaker unit so that they can rotate freely, but with a hinge, the speaker unit can be fixed in any direction, that is, rotate. The heavy speaker unit swings freely in the direction of rotation and comes into contact with the TV itself, causing damage. Therefore, there has been a demand for a mounting fixture that can freely rotate and restrict the rotation of the TV main body and the speaker section of a television in which the TV main body and the speaker section are separated.

The present invention was devised to meet the above-mentioned demands,
For example, an attempt is made to provide a mounting fixture that allows the speaker section of a TV, in which the TV main body and the speaker section are separate, to be rotatable so that it can be changed in a direction depending on the room, and at the same time to be able to maintain the changed arbitrary direction. The purpose is to

[Means to solve the problem]

In order to achieve the above object, the present invention includes: one mounting part 9 in which a cylindrical hinge attachment part 11 shorter than the length in the width direction is formed on one side of a plate-shaped mounting piece 10; A plate-shaped mounting piece 19 paired with the mounting piece 10 at 9 is provided with a bent step 20 for fitting the mounting piece 10 therein.
0 is provided with a recess 21 for removing the fitting of the mounting piece 10, and a cylindrical butterfly part 22 is provided on one side of the recess 21 at a position that is continuous with and coaxial with the cylindrical part 11. The other mounting part 18
and a cylindrical part 11 for attaching a butterfly in the one mounting part 9.
and the cylindrical part 2 for attaching the butterfly in the other mounting part 18.
2 on the same axis, and the butterfly shaft 12 is prevented from rotating with respect to the butterfly mounting cylindrical portion 22.
and a cylindrical part 11 for attaching a butterfly in the one mounting part 9.
A rotation restrictor made of a friction material such as rubber or synthetic resin, which is installed internally to prevent rotation relative to the butterfly shaft 12 and whose inner diameter surface is set in close contact with the outer surface of the butterfly shaft 12 to restrict rotation relative to the butterfly shaft 12. The present invention aims to provide a fixture consisting of an object 17 and the following.

[Effect]

The speaker section is attached to the TV main body by fixing the mounting piece 19 of the other mounting section 18 configured as described above to, for example, the main television body, and fixing the mounting piece 10 of the mounting section 9 to the secondary speaker section. When the speaker section is held and pushed in any direction, the pivoted mounting section 9 is also rotated together with the speaker section with the cylindrical section 11 as the center of rotation. The rotation restricting object whose rotation is prevented by the cylindrical portion 11 also tries to rotate in the same way. However, the inner diameter surface of this rotation regulating object is brought into close contact with the outer surface of the butterfly shaft to restrict its rotation with respect to the butterfly shaft, and the butterfly shaft is fixed to the mounting portion 9.
Since rotation is prevented with respect to the butterfly mounting cylindrical portion 11, the speaker portion is rotated while generating frictional resistance only on the inner diameter surface of the rotation restricting member and the outer surface of the butterfly shaft. If the pushing movement is stopped when the speaker section is set in an arbitrary direction, the rotation of the speaker section also stops at the same time, and the angle after the displacement of the speaker section can be maintained.

〔Example〕

An embodiment of the present invention will be described based on the accompanying drawings. FIG. 1A is a reference perspective view showing a state in which the mounting fixture of the present invention is attached to, for example, a TV 1 main body and a speaker unit 2 that are separated, and is placed on a TV base 3 in the form of a casing. Attachments 8 made of metal or synthetic resin are attached to the side plate 4 or back plate 5 of the television body 1 installed in the TV body 1 and the side plate 6 or back plate 7 of the speaker unit 2, so that the speaker unit 2 can be freely rotated to the television body 1. It is installed so that rotation can be controlled.
Moreover, what is shown in FIG. One piece is attached. Details of the fixture 8 are shown in FIGS. 2 and below. That is,
The reference numeral 9 in the figure is one of the attachment parts made of metal, synthetic resin, etc., and as an example of the attachment part 9, the reference numeral 10 in the figure is a plate-shaped attachment piece. At the center of one side, a cylindrical part 11 for attaching a butterfly, which is shorter than the length in the width direction, is integrally formed eccentrically. A shaft hole 13 is formed on the inner surface of the cylindrical portion 11 and is large enough to pass through a cylindrical butterfly shaft 12 made of metal or synthetic resin. Division 15 has been established. Then, the butterfly shaft 12 is fitted into the expanded portion 15 and attached to the inner surface.
Rubber with a shaft hole 16 large enough to be in close contact with the
Alternatively, a cylindrical rotation regulating member 17 made of synthetic resin is installed inside. Further, the reference numeral 18 in the figure is the other mounting part that is paired with the one mounting part 8, and an example of the mounting part 18 is a plate-shaped mounting piece 19 made of metal, synthetic resin, or the like. The mounting piece 10 is located approximately in the center of the
A bent step 20 is formed in order to fit into the bent step 20, and a recess 21 for unfitting one of the mounting pieces 10 is provided approximately in the center of the bent step 20, and the above-mentioned A cylindrical part 1 for attaching a butterfly provided in the center of the mounting piece 10
The other butterfly attaching cylindrical part 22 positioned on the same straight line as 1 is integrally formed, and a shaft hole 23 of a size that can penetrate the butterfly shaft 12 is formed on the inner surface of the cylindrical part 22. 23. An enlarged portion 2 is formed at one end of the butterfly shaft 12 in order to embed a polygonal anti-rotation piece 24 having an outer diameter larger than the outer diameter of the butterfly shaft 12 formed at one end of the butterfly shaft 12.
5, and the other end is provided with an enlarged portion 27 large enough to accommodate a spring 26 for inserting the butterfly shaft 12 in order to adjust the pivoting force when the butterfly shaft 12 is mounted. There is.

One mounting piece 1 of the mounting fixture 8 configured as described above
0 to, for example, the side plate 6 or back plate 7 of the speaker unit 2, an opening 28 is formed in the mounting piece 10, and the side plate 6 or back plate 7 of the speaker unit 2 is brought into contact with the mounting piece 10. Then, it is fixed through the opening 28 with screws 29 or the like, and the other mounting piece 20 is similarly fixed to the side plate 4 or the back plate 5 of the television main body 1. The cylindrical portion 1 of the one mounting piece 10 is
1 on the same straight line as the other cylindrical part 22,
Injection is made from the tip of the enlarged part 25 opened at one end of the other cylindrical part 22 so as to fit the rotation prevention piece 24 provided at the base end of the butterfly shaft 12, and the butterfly is passed through between the cylindrical parts 22 and 22. A spring 26 is placed on the tip of the butterfly shaft 12 to lock the shaft 12, a washer 30 is placed on the tip of the butterfly shaft 12 to prevent the spring 26 from coming off, and a nut 32 is attached to the threaded portion 31 formed on the tip of the butterfly shaft 12.
It is screwed on. By attaching the TV main body 1 and the speaker section 2 in this way, the speaker section 2 is supported by the mounting bracket 8, and when the speaker section is held and pushed in any direction, the mounting section 9, which is pivoted, is also supported by the mounting tool 8. The speaker section 2 is rotated about the cylindrical section 11 as the center of rotation, but during this rotation, the rotation restricting member 17, which is prevented from rotating by the cylindrical section 11, also tries to rotate. However, the inner diameter surface of this rotation regulating member 17 is brought into close contact with the outer surface of the butterfly shaft 12 to restrict its rotation with respect to the butterfly shaft 12, and the butterfly shaft 12 is attached to the butterfly mounting cylindrical portion 11 of the mounting portion 9. On the other hand, since rotation is prevented, the speaker section is rotated while generating frictional resistance only on the inner diameter surface of the rotation restricting member 17 and the outer surface of the butterfly shaft 12. If the speaker part is set in an arbitrary direction and the pushing is stopped, the rotation of the speaker part will also stop at the same time, but since the inner diameter surface of the rotation restricting member 17 and the butterfly shaft 12 are in close contact with each other, this rotation restricting member The angle of the speaker section after displacement can be maintained by the elastic resistance and frictional resistance of 11.

Furthermore, another embodiment shown in FIG. 4 is one in which one of the mounting parts 9 of the fixture 8 of the present invention is fixed to the lighting fixture 33, and the other mounting part 18 is fixed to the back of the top plate of the desk 34, for example. If it is attached to the lower surface of an upright shelf 35, the lighting fixture 33 can be supported and displaced as shown by the imaginary line in the figure, and can also be used as a fixture 8 that can maintain a desired lighting direction.

[Effect of idea]

As mentioned above, according to the present invention, the other mounting piece attached to the side plate or back plate of the main TV body is screwed to the one mounting piece attached to the side plate or back plate of the secondary speaker unit. The speaker part can be rotated freely, so when installed in a room, the angle of the speaker part can be adjusted according to the size of the room and the number of people. Since the inner surface of the object and the outer surface of the butterfly shaft are in close contact, rotation is restricted and the angle after angle adjustment is maintained. Furthermore, since one mounting part attached to the TV body supports the other mounting part attached to the speaker part, there is no need for a base to support the speaker part, and all you need is a base to support the TV body, so it is small. It can be installed anywhere. Further, since the rotation regulating object is prevented from rotating with respect to the butterfly mounting cylindrical part, the rotation regulating object does not rotate at the same time as the butterfly shaft rotates, and the rotation regulating object itself is prevented from being twisted or the like. It won't twist or tear. Further, the bent step portion 20 formed on the mounting portion 9 allows the mounting pieces 10 and 19 to be flush with each other when they are fitted together.
When removing the fitting, the fitting can be easily released by inserting a finger or the like into the recess 21 formed in the stepped portion 20 and pulling it.
