Description

Folding device for display unit {A FOLDABLE PIVOT DEVICE FOR A LCD SCREEEN}

The present invention relates to a shaft device that can fold the display device, and more particularly to a shaft device that can be positioned horizontally by rotating the display device in the direction of the underlay as necessary through the locking device of the elastic member on the rotary shaft.

The display device is an output device of a computer. Conventionally, the CRT has been used as a video display device. However, in recent years, liquid crystal display devices for displaying an image using liquid crystal have been widely used. This is because the use of the liquid crystal display device can significantly reduce the installation space compared to the conventional CRT, and because the resolution of the image is also higher than the conventional CRT, it has been favored by consumers.

The above-mentioned liquid crystal display device is generally a plate-shaped screen body connected to the base plate via a shaft, and in actual use, the angle of the screen body and the base plate is adjusted so as to be suitable for the user to use.

10 is a perspective view showing a shaft device of a conventional display device. As shown in FIG. 10, the connection structure of the underlay 60 and the screen main body 90 is provided with a position fixing frame 62 on the underlay 60 and the rear surface of the screen main body 90 ( The fixing member 80 is installed in the rear surface, and the elevation angle of the display apparatus is adjusted together with the shaft 70. However, since the design of the position fixing shaft is designed according to the actual use state, it is easy to adjust the elevation angle of the display device, but it is difficult for the display device to be completely rotated in the underlay direction to be horizontal. For this reason, not only does it occupy a lot of space at the time of packaging of a display apparatus, but it also increases the difficulty at the time of carrying, and it is inferior in economic efficiency.

In order to solve the above problems, the inventors of the present invention have devised the present invention with practicality and progress through many studies and improvement measures.

The present invention folds the display device so that it is parallel to the underlay, thereby reducing the packaging volume of the display device and reducing the packaging cost, and also being able to fold the display device to prevent damage caused by shocks during packaging or transportation. The main purpose is to provide.
