Description

  The present invention relates to a stand, and more particularly, to a stand that can support supported parts having different positions of the center of gravity.

  In recent years, research and development of thin displays such as liquid crystal displays and plasma displays have progressed, and products with larger and thinner displays have been developed.

  However, as the display becomes larger and thinner, the risk of falling increases, and the technology related to the structure of the stand for supporting the display for preventing the falling has become important.

  As a proposal regarding a display stand, a proposal has been made to prevent a fall by providing a stable leg on the stand. Further, Patent Document 1 discloses that a stable leg can be easily stored in the stand when the stable leg is not used. Proposals have been made to stabilize the video display device when in use, and not to detract from aesthetics when not in use.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing an example of an overview of a display device 10 according to the present embodiment. FIG. 1 shows a display device 10, a display device 11, and a stand 12.

  The display device 10 is a thin display device such as a liquid crystal display or a plasma display, and has a function of displaying an image. The video information displayed on the display device 10 may be generated by a video generation unit or input from the outside. As the video generation unit, for example, a graphic board for drawing a graphic, a DVD player for reproducing video content, and the like can be considered. The display device 10 is a supported body supported by a stand 12.

  The display device 11 is an image display unit that displays an image on the display device 10, and displays image information output from the display device 10 toward the front of the display device 10.

  The stand 12 is provided below the display device 11 and supports the display device 11 vertically from below.

  FIG. 2 is a side view showing an example of the display device and its center of gravity position in the present embodiment. FIG. 2 shows a set a21, a set b22, a display device 23, a stand 24, a gravity center position a25, a display device 26, a stand 27, and a gravity center position b28. In the following description, it is assumed that the direction in which the display device 10 performs display (left direction in FIG. 2) is the front direction, and the opposite direction (right direction in FIG. 2) is the rear direction.

Here, the display device 23 of the set a21 and the display device 26 of the set b22 have the same external shape, but have different internal structures, and have different center-of-gravity positions in the front-rear direction.

The set a <b> 21 is a set of display devices when the center of gravity position a <b> 25 of the display device 23 is present vertically above the center position with respect to the front-rear direction of the stand 24.

  The set b22 is a set of display devices in the case where the center of gravity position b28 of the display device 26 is present in a vertically upward direction at a position ahead of the center of the stand 27 in the front-rear direction.

  Regarding the set a21, an angle between a straight line passing through the gravity center position a25 and vertically downward and a straight line passing through the gravity center position a25 and the front end of the stand 24, or a straight line passing through the important position a25 and the rear end of the stand 24. Each of the angles is 10 °. As described above, in order to stabilize the display device, the angle is desirably a certain angle or more, and if the angle is less than the angle, sufficient stability cannot be obtained. In the present embodiment, the angle of 10 ° is exemplified as a sufficient angle for stabilizing the display device. However, this is merely an example and the present invention is not limited to this. Normally, in this way, the positional relationship between the position of the center of gravity of the display device and the grounding portion of the stand is very important in the design of the display device.

  In the set b22, the angle in the rear end direction is 10 ° or more, but the angle in the front end direction is less than 10 °. In this case, since the forward angle is less than 10 °, the display device 26 tends to fall forward.

  For example, when the position of the center of gravity of the display device changes from set a21 to set b22 due to a design change inside the display device, the angles are conventionally 10 ° or more (an area where the installation area can be stabilized). So the stand was redesigned.
