TECHNICAL FIELD OF THE INVENTION
The present invention relates to a position adjusting mechanism for a stand-type thin display device, and more particularly to a position adjusting mechanism for keeping a display screen portion horizontal in a large stand-type thin display device having a rotating mechanism.
[0002]
[Prior art]
In recent years, stand-type thin display devices having a display screen such as a liquid crystal display or a plasma display have become widespread. In particular, a demand for a large-sized stand-type thin display device having a display screen section exceeding 30 inches is increasing, and various products for business use or home use are being developed.
[0003]
In such a stand-type thin display device, a display screen portion made of a liquid crystal display or a plasma display, and a main body portion including devices such as an amplifier, a power supply unit, and a drive circuit are combined with a stand portion having legs extending over a horizontal plane. Typically, the supporting structure allows the display screen to stand upright substantially perpendicular to the floor. Further, the stand has a rotation mechanism, and is configured to rotatably support the main body.
[0004]
FIG. 1 is a front view showing an example of the stand type thin display device. In FIG. 1, a thin display device 100 is a console-type thin display device including a display screen section 110, a main body section 120, and a stand section 130. Here, the console type is a thin display device of a type in which a control unit 121 including a power supply unit, a drive circuit, a control circuit, and the like, and an amplifier unit 122 are configured as a main body unit 120 and integrated with the display screen unit 110. Say that.
[0005]
The display screen section 110 has a display screen 111 formed of a liquid crystal display, a plasma display, or the like. The main body unit 120 has a control unit 121 and an amplifier unit 122, is integrated with the display screen unit 110, and is supported by the stand unit 130. The stand 130 includes a stand support 131 and a stand base 132. The stand support 131 includes a rotation mechanism that can support the main body 120 in a freely rotatable manner.
[0006]
Conventionally, as an example of a rotating mechanism of such a stand type thin display device, a rotating mechanism of a television disclosed in Patent Document 1 has been considered. In this rotation mechanism, sliding rollers 7 for supporting the load of the television main body and rolling the television main body are arranged at both side edges of the bottom of the television main body. Is characterized in that it rotates.
[0007]
However, it is difficult to apply the rotation mechanism of the television described in Patent Document 1 to the rotation mechanism of the stand-type thin display device. In the rotating mechanism described in Patent Literature 1, since the television body and the rollers roll and rotate, the television body and the television stand must have a certain width and depth. In addition, there is a problem that a gap is formed between the television body and the television stand, and that the inside of the television stand is visible when the television body is rotated.
[Patent Document 1]
JP-A-08-331485 (FIG. 6).
[0008]
[Problems to be solved by the invention]
As the stand-type thin display device becomes larger, the display screen portion becomes larger and a considerable weight must be supported by the stand portion. At this time, it is necessary to hold the display screen horizontally. In particular, in the case of a large stand-type thin display device, even if the horizontal position is slightly inclined, the difference in height between the left and right ends of the wide display screen portion becomes large, so that the horizontal position is not noticeable to the user's eyes. Appears to be greatly inclined. For example, it is known that in a certain large liquid crystal television, if the horizontal position has an inclination of 20 minutes or more (about 1/3 degree) or more, the inclination is recognized by the user's eyes.
[0009]
In addition, the stand type thin display device is typically configured so that the main body can be rotated manually or automatically with respect to the stand. However, the main body is horizontally rotated so that the main body does not swing right and left during rotation. It is necessary to stabilize the position.
[0010]
However, no matter how precisely the horizontal position of the main body is designed, the dimensions of each part may actually vary slightly, or a slight error may occur in the positioning between the parts during assembly. It is very difficult to manufacture a stand-type thin display device in which the horizontal position of the main body is precisely held as designed.
Therefore, in view of the above problems, the present invention provides a position adjusting mechanism for keeping a display screen horizontal in a stand-type thin display device having a rotating mechanism.
[0011]

The present invention is an apparatus in which a main body is supported by a stand, and a device for adjusting a mounting position of the stand and the main body in a mounting portion between the stand and the main body. Equipment that is available.
[0012]
Further, the present invention is a thin display device including a display screen portion and a stand portion supporting the display screen portion, wherein the stand portion and the display screen portion are attached to each other at the stand portion and the display screen portion. It is an object of the present invention to provide a device having a position adjusting means for adjusting a mounting position of a main body.
[0013]
The mounting of the stand section and the display screen section is temporarily fixed, and after the mounting position is adjusted by the position adjusting means, the stand section and the display screen section are permanently fixed. Further, the position adjusting means is provided with an eccentric member at the mounting portion.
[0014]
The present invention is also a thin display device provided with a display screen section and a stand section supporting the display screen section, and a position adjusting mechanism for adjusting a mounting position of the stand section and the main body section.

[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The position adjusting mechanism of the present invention is typically used in a stand support section of a stand type thin display device as shown in FIG. 2 to 7 are configuration examples of each part of the stand-type thin display device shown in FIG. 1, and in each drawing, the same reference numerals denote the same components. .
[0017]
Hereinafter, an embodiment of the position adjusting mechanism of the present invention will be described. FIG. 2 is a diagram showing a frame structure for supporting a display screen unit and a main body of a stand-type thin display device including the position adjusting mechanism of the present embodiment.
[0018]
As shown in FIG. 2, in the stand-type thin display device, the rotating unit 210 of the stand unit rotatably supports the aluminum frame 230 via the mounting angle 220.
The position adjusting mechanism of the present embodiment positions and fixes the rotation unit 210 and the mounting angle 220 fixed thereto to the aluminum frame 230.
[0019]
FIGS. 3, 4, and 5 are a rear view, a side view, and a top view, respectively, showing the rotary unit 210 and the mounting angle 220 of the stand unit shown in FIG. 2 in an enlarged manner.
3 to 5, the mounting angle 220 has a positioning pin 310, fixing holes 321-326, and position adjusting holes 331-332. The positioning pin 310 engages with a boss 231 (see FIG. 2) from the front panel (plastic) penetrating the aluminum frame 230 to determine an approximate position at which the mounting angle 220 is mounted to the aluminum frame 230. It is. The fixing holes 321 to 326 are for inserting screws, and the position adjusting holes 331 to 332 are for finely adjusting the mounting position of the mounting angle 220 and the aluminum frame 230 as described later.
[0020]
Next, the attachment of the rotating unit 210 and the attachment angle 220 to the aluminum frame 230 will be described. FIG. 6 is a top view in a state where the rotating unit 210, the mounting angle 220, and the aluminum frame 230 are mounted.
[0021]
First, each positioning pin 310 of the mounting angle 220 is inserted into each boss 231 from the front panel (plastic) penetrating the aluminum frame 230 to position the mounting position. Next, the fixing holes 321 are screwed. At this time, the fixing hole 321 is screwed to the extent that the angle 220 can be slightly rotated with respect to the aluminum frame 230 by attaching the screw of the fixing hole 321 to the center. Subsequently, the other fixing holes 322 to 326 are temporarily screwed. At this time, the thin display device is temporarily fixed with a torque that does not naturally tilt due to its own weight.
[0022]
Next, the mounting positions of the rotating unit 210, the mounting angle 220, and the aluminum frame 230 are finely adjusted. FIG. 7 is a rear view of the rotation unit and the mounting angle similar to FIG. 3, but shows a state where the eccentric cam 341 is inserted into the position adjustment hole 331.
[0023]
In the present embodiment, the screw head of the eccentric cam 341 has an oval shape. Therefore, as the eccentric cam 341 is rotated, the diameter of the screw head in the vertical direction changes. In FIG. 7, when the eccentric cam 341 is rotated to the right, the diameter increases in the vertical direction, so that the upper inner wall of the position adjustment hole 331 is pushed upward by the eccentric cam 341.
[0024]
When it is desired to adjust the position in the opposite direction, the eccentric cam 341 is loaded into the position adjusting hole 332 and the eccentric cam 341 lowers the inner wall of the position adjusting hole 332 by rotating the eccentric cam 341 to the left. It can be pushed down in the direction.
[0025]
At this time, as described above, the mounting angle is slightly rotated around the screwing of the fixing hole 321 as an axis. Therefore, while the eccentric cam 341 is being rotated, by finely adjusting the mounting position between the rotating unit 210 and the mounting angle 220 and the aluminum frame 230, the position is adjusted so that the display screen and the main body of the thin display device are horizontal. Can be fine-tuned.
After fine adjustment of the mounting position, the fixing holes 322 to 326 temporarily screwed may be permanently screwed, and the rotating unit 210 and the mounting angle 220 and the aluminum frame 230 may be permanently fixed.
[0026]
In addition, the eccentric cam 341 can be formed in various shapes as long as it is asymmetric with respect to the rotation center. For example, a shape such as an ellipse or an eccentric circle can also function as a position adjustment mechanism similar to the above.
[0027]
Note that the installation positions of the fixing holes 321 to 326 and the position adjustment holes 331 to 332 on the mounting angle 220 shown in FIGS. 3 and 7 are only one embodiment, and other various embodiments may be used. You can think.
[0028]
As described above, as an embodiment of the position adjusting mechanism of the present invention, an example in which the position adjusting mechanism is used in a stand supporting portion of a stand-type thin display device has been described in detail. However, the position adjusting mechanism of the present invention is applicable to all devices supported by the stand. Is considered possible.
In addition, the position adjusting mechanism of the present invention is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the gist of the present invention.
[0029]
【The invention's effect】
As described above, according to the position adjusting mechanism of the present invention, it is possible to perform fine position adjustment for keeping the display screen horizontal in a stand-type thin display device having a rotating mechanism.
