  The panel fixing portion 2 is fixed to a flat display panel P such as a liquid crystal television or a plasma television, and is a member separate from the display panel P or formed integrally with the display panel P. In this embodiment, as shown in FIGS. 2 to 4, the panel fixing member 2 a is separate from the display panel P. The display panel P is a display such as the above-described liquid crystal television, plasma television, or computer output screen, and is preferably a so-called thin display panel. There are various things.

  The panel fixing member 2a is a member in which the front surface is fixed to the back surface of the display panel P and the pivot portion 53 is fixed to the back surface. In the present embodiment, the upper frame 21 made of a square member having a substantially rectangular cross section and A lower frame 22 and a left frame 23 and a right frame 24, which have a substantially U-shaped cross section and have increased strength, are framed in a substantially rectangular shape.

  A support fixing portion for supporting and fixing the display panel P is provided on the front surface of the panel fixing member 2a, and a supported fixing portion supported and fixed on the support fixing portion is provided on the back surface of the display panel P. .

The

  Although not described in detail, the symbol KP in the drawing is a decorative panel, the symbol R is a rack, and the symbol L is a lever for restricting the pivoting portion 4 in the pivoting portion 5.

  The operation of the above-described display panel support device will be described.

  As shown in FIG. 5, in order to place the display panel P in the retracted state along the wall surface W, the main arm 31 is moved to the wall surface W by bringing both left and right ends of the display panel P close to the wall surface W. The display panel P also becomes parallel to the wall surface W at the same time as it is laid on the side (that is, the angle between the wall surface W and the lateral direction of the main arm 31 is reduced). The pivoted portion 4 at the end rotates around the pivoted portion 51 of the main plate 12, and the pivoted portion 4 at the other side end rotates around the pivoted portion 53 of the panel fixing member 2a. The sub arm 32 is also laid down against the wall surface W. At this time, in the sub arm 32, the pivotally supported portion 4 at the other side end rotates around the pivot 53 of the panel fixing member 2a. The pivotally supported portion 4 of the part rotates around the pivotal support portion 52 of the roller 61 and moves the guide rail 62 together with the roller 61. Eventually, the main arm 31 and the sub arm 32 are parallel to the wall surface W, and the display panel P is also parallel to the wall surface W, so that the display panel P is stored along the wall surface W via the main arm 31 and the sub arm 32. . Of course, the display panel P may be used even in the housed state (for example, when the display panel P is a television, the television is watched).

  Next, as shown in FIG. 6A, in order to make the display panel P project from the wall surface W in parallel with the wall surface W, the left and right side edges of the display panel P are equidistant from the wall surface W. What is necessary is just to position it. The horizontal position of the display panel P at this time is determined by the main arm 31. This is because the pivotally supported portions 4 at both side ends of the main arm 31 are pivotally supported by a pivotal portion 51 fixed to the wall surface W side and a pivotal portion 53 fixed to the display panel P side, Depending on the distance from the wall surface W of the display panel P (here, the pivot portion 53), the main arm 31 rotates about the pivoted portion 4 pivotally supported by the pivot portion 51 on the wall surface W side. The angle formed is determined, and the position is determined so that the display panel P rotates around the pivotal support portion 53 on the display panel P side and is parallel to the wall surface W. At this time, when the position of the sub arm 32 relative to the wall surface W of the display panel P is determined, the position of the pivotally supported portion 4 pivotally supported by the pivotal support portion 53 on the display panel P side is determined. The pivotal support 52 moves along with the roller 61 in the guide rail 62 to determine the position. For this reason, the position of the pivot portion 52 that pivotally supports the pivoted portion 4 on the wall surface W side of the sub arm 32 varies in the left-right direction according to the distance from the wall surface W of the display panel P. In FIG. 6A, as the display panel P moves away from the wall surface W, the roller 61 is positioned on the left side and the display panel P is positioned on the left side. The state in which the roller 61 is positioned at the left side end of the stroke in the guide rail 62 is the state in which the display panel P is farthest from the wall surface W.

  Next, in order to tilt the display panel P with respect to the wall surface W, for example, as shown in FIG. 6B, the right side end of the display panel P is positioned forward of the left side end, The display panel P is tilted so as to make an angle of 30 ° with respect to the wall surface W, or the left side edge of the display panel P is positioned forward of the right side edge as shown in FIG. P can be inclined with respect to the wall surface W at 30 °. In any case, the pivotal support portion 53 on the display panel P side is located in front of the housed state. Further, from this state, the tilt of the display panel P can be changed without changing the distance from the wall surface W of the pivot 53, or the distance from the wall W of the pivot 53 can be changed while the display panel P is tilted. The distance from the wall surface W of the panel P and the inclination with respect to the wall surface W can be set independently. Also in this case, as described in the description of FIG. 6A, the display panel P is positioned on the left side as the distance from the wall surface W of the pivotal support portion 53 becomes longer.

  As described above, in the display panel support device, there is left-right asymmetry in which the horizontal position of the display panel P changes depending on the distance from the wall surface W of the display panel P. Since the fixing to the base plate 11 is arbitrary in the lateral direction, the distance from the wall surface W of the display panel P can be achieved by reversing the left and right positions of the main plate 12, the main arm 31, the sub plate 13, and the sub arm 32. The change in the position of the display panel P in the left-right direction according to the direction is reversed left and right, so that the user can select the one that is easier to use.

  In the display panel support device of the present invention, the connecting member 3 is composed of two members, the main arm 31 (first connecting member) and the sub arm 32 (second connecting member). As in the conventional example composed of two members, the rotation operation of the display panel P does not become unstable. Moreover, since the connection member 3 consists of two members, since the load concerning one member is halved compared with a prior art example, possibility that it will be damaged is very low. Even if any one of the connecting members 3 is broken, the display panel P can be supported by the other connecting member 3, and there is no risk of the display panel P falling, and the appearance is safe. improves.

  Further, when the display panel P is installed on the one wall surface W of the corner portion of the room so that the display panel P is almost in contact with the adjacent wall surface W, the adjacent wall surface W is close even if the display panel P is viewed in the stored state. Although it is difficult to see, if the display panel P moves in a direction away from the adjacent wall surface W when the display panel P protrudes from the one wall surface W, the distance from the adjacent wall surface W becomes longer and displayed. The panel P becomes easy to see.
