Description

  The present invention allows a flat display such as a liquid crystal display or a plasma display to be manually rotated in the horizontal direction, tilted (tilted or raised) manually in the front-rear direction, or moved up and down manually. The present invention relates to a hinge device for a flat display.

  As a conventional flat display hinge device, there is a display support device (see, for example, Patent Document 1) that can change the orientation (horizontal angle / elevation angle) of a heavy display panel. In addition, there has been a display monitor stand in which the one-way clutch and the torque limiter constituting the friction mechanism create weak friction when the elevating member moves upward, and the display monitor is moved up and down. (For example, see Patent Document 2)

However, any of the above conventional devices can manually and quickly rotate the flat display in the left and right horizontal direction, manually tilt in the front and rear direction (tilt, up and down), or vertically. It was not moved up and down manually.
