In this embodiment, the upper frame 21 and the lower frame whose longitudinal direction is the left-right direction. The main body is constituted by 22, and two support members 7 having a longitudinal direction as a longitudinal direction are installed between the upper frame 21 and the lower frame 22.

  The support member 7 has a substantially U-shape with a planar cross section opened rearward, and is provided from the upper end edge toward the rear, and is provided below the horizontal piece 71a and the rear end of the horizontal piece 71a. A substantially fixed L-shaped upper fixing portion 71 made of 71b is provided. Further, a flat plate-like lower fixing portion 72 extending rearward is provided at the lower end edge. A fixing hole 71 c is formed in the vertical piece 71 b of the upper fixing portion 71.

  A plurality of fixing holes 21a are formed in the upper frame 21 of the panel fixing portion 2 in the left-right direction, and the fixing holes 71a of the upper fixing portion 71 of the support member 7 are communicated with the desired fixing holes 21a. By fixing a fixing tool (not shown), the support member 7 can be fixed at any desired position in the left-right direction of the upper frame 21.

The fixing member 72 (not shown) is fixed by communicating the fixing hole 72a of the lower fixing portion 72 of the support member 7 with the desired fixing hole of the frame 22, so that the support member 7 can be arbitrarily fixed in the left-right direction of the lower frame 21. Can be fixed at a desired position.

  A support fixing part for supporting and fixing the display panel P is provided on the front surface of the support member 7, and a supported fixing part supported and fixed on the support fixing part is provided on the back surface of the display panel P. In some cases, the relative positions of the supported fixing portions differ depending on the display panel P. In the display panel P of the present embodiment, a total of four supported vertical portions, two in the horizontal direction and two in the vertical direction. A supported fixing portion is provided, and the interval between the upper and lower supported fixing portions is constant regardless of the display panel P, and the interval between the left and right supported fixing portions is different depending on the display panel P. As the supported fixing portion, a protruding portion 26 is formed in which the diameter of the protruding base is smaller than the prepared hole and the diameter of the protruding tip is smaller than the upper hole and larger than the prepared hole.

  In addition, as shown in FIG. 5, so-called saddle holes 25 formed by connecting a large diameter upper hole and a small diameter lower hole are formed at the upper and lower portions of the support member 7 of the panel fixing portion 2 as the support fixing portion. In order to support and fix the display panel P to the panel fixing part 2, the protruding tip part of the protruding part 26 of the display panel P is inserted into the upper hole of the dart hole 25 of the panel fixing part 2 from the front, respectively. By moving the projecting base inserted through the hole into the pilot hole and engaging it, the projecting base is placed and supported on the lower edge of the pilot hole, and the protruding tip is larger than the diameter of the pilot hole Is secured and fixed.

  In this way, the left and right positions of the support fixing portion provided on the front surface of the panel fixing portion 2 can be changed, and various types of panel fixing portions 2 having different positions of the support fixing portions for each display panel P are prepared. There is no need, and one panel fixing part 2 can correspond to different display panels P.

  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. 6, in order to place the display panel P along the wall surface W, the left and right ends of the display panel P are brought close to the wall surface W so that the main arm 31 is moved 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 portion 2. Then, the sub arm 32 is also laid down on the wall surface W. At this time, the sub arm 32 is rotated around the pivot portion 53 of the panel fixing portion 2 by the pivoted support portion 4 at the other side end portion. 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. 7A, 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. 7A, 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. 7B, 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. 7A, the display panel P is positioned on the left side as the distance from the wall surface W of the pivotal support 53 increases.

  Thus, in the display panel support device of the present embodiment, 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 in which 3 is a single member, 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.

  Next, another embodiment of the support member 7 will be described with reference to FIGS. Also in this embodiment, since most of them are the same as those in the above embodiment, the description of the same parts is omitted, and different parts are mainly described.

  The panel fixing unit 2 is mainly composed of the base plate 20 instead of the upper frame 21 and the lower frame 22 as in the above embodiment.

  As shown in FIGS. 9 and 10, the support member 7 has a substantially U-shaped planar cross section that opens forward, and is provided from the upper edge toward the rear to provide a horizontal piece 71 a and a rear end of the horizontal piece 71 a. An upper fixing portion 71 having a substantially inverted L shape composed of a vertical piece 71b continuously provided below is provided, and a fixing hole 72a is formed at the lower end portion.

  The support member 7 can hook and hold the vertical piece 71b from the front of the base plate 20 to any left and right positions of the upper end edge of the pace plate 20.

  The base plate 20 is formed with a plurality of fixing holes 22a in the left and right direction at the lower end, and the fixing tool (not shown) is fixed by connecting the fixing holes 72a of the support member 7 to the desired fixing holes 22a. Thus, as shown in FIGS. 11A and 11B, the support member 7 can be fixed to any desired position in the left-right direction of the base plate 20.

  As shown in FIG. 12, a vertical movement member 8 is fixed to an arbitrary position on the support member 7. The vertical movement member 8 has a substantially box shape that opens rearward. The vertical movement member 8 can be inserted between the both side pieces of the support member 7, and a dart hole 25 is formed in the front surface. And the locking piece 81 of the substantially L shape which bends below in the middle on the left and right both sides protrudes. The support member 7 has a plurality of cutouts 73 formed in the vertical direction at the front end of the side piece.

  The vertically moving member 8 can be installed at any desired height of the support member 7 by inserting the locking piece 81 into a desired notch 73 of the support member 7 and locking it.

  In this way, not only the left and right positions of the support fixing portion provided on the front surface of the base plate 20 can be changed, but the vertical positions can be changed, and it is possible to deal with display panels of various specifications.
