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

  As shown in FIG. 11, in order to bring the display panel P into the storage state along the wall surface W, the left and right side 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 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. 12A, in order to make the display panel P protrude from the wall surface W in parallel with the wall surface W, the left and right ends 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 pivoted support portion 4 pivotally supported by the pivot 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. 12A, 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. 12B, the right side edge of the display panel P is positioned forward of the left side edge, 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. 12A, 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 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 consisting of one 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.

  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.

  The operation of the lock means 7 will be described. When the rotation of the main arm 31 and the sub arm 32 with respect to the display panel P is not locked, as shown in FIG. 5, when the tip of the lever L is raised, the lever L rotates counterclockwise in the figure. The other end of the second link member 75 descends, the second link member 75 rotates clockwise, and the bent portion rises obliquely upward to the left. When the other end of the first link member 74 rises diagonally to the left, the holding member 73 is constrained so as to move up and down in the bracket B. Therefore, the first link member 74 is connected to the holding member 73 by a pin 74a. One end of one link member 74 rises, and the holding member 73 and the panel-side engagement member 72 rise. As a result, the engagement between the arm-side engagement member 71 and the panel-side engagement member 72 is released, and the main arm 31 and the sub-arm 32 can be rotated with respect to the display panel P.

  When locking the rotation of the main arm 31 and the sub arm 32 relative to the display panel P, as shown in FIG. 6, when the tip of the lever L is lowered, the lever L rotates clockwise in the figure. The other end of the second link member 75 rises, the second link member 75 rotates counterclockwise, and the bent portion descends diagonally downward to the right. When the other end of the first link member 74 descends diagonally to the right, one end of the first link member 74 connected to the holding member 73 by a pin 74a is lowered, and the holding member 73 and the panel-side meshing member 72 are moved. Descends. As a result, the arm-side engagement member 71 and the panel-side engagement member 72 are engaged with each other, and the rotation of the main arm 31 and the sub arm 32 with respect to the display panel P is locked.

  Thus, in the present invention, the locking means 7 locks the rotation of the main arm 31 and the sub arm 32 with respect to the display panel P, and the display panel moves unexpectedly, or the display panel moves vigorously, and the wall, furniture, It is prevented from colliding with people.

  Further, in order to prevent the lever L from moving unexpectedly and releasing the lock, a self-locking means for automatically locking may be provided. In the case of this embodiment, as shown in FIGS. 5 and 6, the biasing means 8 formed of a coil spring is biased so that the gripping portion side is biased downward relative to the portion pivotally supported by the support member 76 of the lever L. May be provided on the back surface of the panel fixing member 2a, or although not shown, a heavy object serving as a weight may be provided closer to the gripping portion than a portion pivotally supported by the support member 76 of the lever L. This prevents the lock from being inadvertently released.

  Further, in the present embodiment, by providing the friction member 9 including the arm side friction member 91 and the panel side friction member 92 as described above, the pivoting portion 4 is rotated with respect to the pivot portion 53, that is, the main arm 31 and The rotation of the sub arm 32 with respect to the display panel P is regulated by the frictional force, and can be easily prevented from moving at this pivotal support portion.

  Thereby, for example, due to the weight of the display panel P applied to the main arm 31 and the sub-arm 32 due to the unevenness of the wall surface, the force applied by the wind or the earthquake, or the force applied by the user or something, it is against the intention. It can be prevented that the display panel moves or the display panel moves vigorously and collides with a wall surface, furniture, or a person.

  Further, even if a force exceeding the static friction force between the arm side friction member 91 and the panel side friction member 92 is applied, the braking force due to the dynamic friction acts and the movement can be kept small. Moreover, since it starts to move when the static frictional force is exceeded, it is possible to prevent people from colliding and getting injured.

  Further, in this embodiment, since the biasing means 90 for maintaining the pressure contact force constant is provided between the arm side friction member 91 and the panel side friction member 92, the arm side friction member 91 and Even if the panel side friction member 92 is worn, a constant pressure contact force can be maintained.

  In addition, one panel side friction member 92 can be brought into pressure contact with both the arm side friction members 91 of the main arm 31 and the sub arm 32, and it is not necessary to attach the two friction members 9 to the panel side, so that the installation work is easy. It becomes.

  Further, the pressure contact force between the arm side friction member 91 and the panel side friction member 92 can be adjusted by changing the position of the nut 94b screwed to the bolt 94a.
