- the worm 1311 is engaged with the lower gear of the first gear 1320
- the upper gear of the first gear 1320 is engaged with the upper gear of the second gear 1330
- the lower gear of the second gear 1330 is engaged.
- Third gear ⁇ engages with the upper gear of 340.
- the lower gear of the third gear 1340 is used as an output gear.
- the first gear 1320 is configured as a torque limiter gear for reducing rotation.
- FIG. 15 is an enlarged sectional view showing the structure of the first gear 1320 in detail.
- the first gear 1320 includes a gear base 1321, an upper gear 1322, a lower gear 1323, a spring 1324, and a friction material 1325.
- the upper gear 1322 is fixed to and integrated with the gear base 1321, and the lower gear 1323 is rotatably held on the shaft portion of the gear base 1321.
- the spring 1324 is a spring made of ordinary metal or the like, and always presses the upper gear 1322 and the lower gear 1323.
- the friction material 1325 is made of a material such as felt, is fixed to the gear base 1321 by an adhesive or the like, and is integrated therewith.
- the gear base 1321 of the first gear 1320 and the lower gear 1323 are frictionally slid by the friction material 1325 as described above.
- a static friction force acts between the friction material 1325 and the lower gear 1323, and the rotation of the worm 1311 is directly changed to the gear base 1321 and the upper It is transmitted to the gear 1322.
- the rotating unit even when the rotating unit is stopped, the user may manually apply an excessive rotating load. Even in such a case, since the rotational load input from the lower gear of the third gear 1340 is reduced by the first gear 1320, the configuration is such that no excessive load is applied to each member.
- the friction coefficient between the gear base 1321 of the first gear 1320 and the lower gear 1323 can be adjusted. Is possible.
- the coefficient of friction can be adjusted by selecting the material of the friction material 1325 as a matter of course.
- the stand-type thin display device of the present embodiment has a position sensor 1350 in the rotating mechanism.
- the position sensor 1350 can be used to detect the current rotational position by detecting the inner wall of the rotating unit.
- the stand-type thin display device of the present embodiment when installed in a house or the like, it does not rotate due to wind pressure or the like, but generates a rotational torque enough to rotate when a user applies a light rotational load. It is preferable to provide a rotating mechanism having the above. For example, it is preferable to design so that the friction material 1325 and the lower gear 1323 slide with a load of about 1.5 kg. As described above, as one embodiment of the present invention, a stand type thin display device
- the torque limiting gear need not be the first gear 1320.
- the second gear 1330 or the third gear 1340 can also be configured as a torque limiter gear similar to the above.
- a configuration may be employed in which two or more torque limiter gears are provided in the rotation mechanism.
- the position adjustment mechanism, the rotary bearing mechanism, and the rotation reduction mechanism of the thin display device according to the present invention have been described in detail with reference to specific embodiments.
- the thin display device according to the present invention is not limited thereto. Not something.
- Those skilled in the art can make various changes and improvements to the configurations and functions of the invention according to each of the above embodiments or other embodiments without departing from the spirit of the invention.
- the position adjusting mechanism of the thin display device of the present invention in the stand type thin display device having the rotating mechanism, it is possible to perform fine position adjustment for keeping the display screen horizontal. It becomes possible.
- the rotary bearing mechanism of the thin display device of the present invention even in a stand-type thin display device in which the center of gravity of the display screen and the main body is separated from the center of rotation of the rotary mechanism of the stand, stable and smooth Rotation becomes possible.
- each member of the stand portion is protected even when an excessive rotation load or an unnatural rotation load is applied to the rotation of the stand portion.
- the thin display device of the present invention includes a liquid crystal display and a plasma display. It can be used for a stand-type thin display device having a display screen such as a screen or an EL display.
