There is an effect to become.

  Hereinafter, the best mode for carrying out a thin display device according to the present invention will be described with reference to the drawings.

  1 to 4 show a first example of the best mode for carrying out a thin display device according to the present invention.

  In the first example, like the thin display device according to Patent Document 1, an installation structure in which the display unit 1 is supported by the support base 2 and the stand 3 is configured (see FIG. 1).

  In the display unit 1, a liquid crystal panel, various substrates, and the like are accommodated in a substantially rectangular housing, and a stand 3 is connected to the back surface of the housing.

  The support base 2 is formed in a substantially H shape in a planar shape as shown in FIG. 2 and is divided into a fixed portion 21 on the front side and a movable portion 22 on the rear side. The fixing portion 21 is substantially U-shaped by a side portion 21a that is a large portion on the front side of both side portions that extend in the front-rear direction of the H-shape and a main body portion 21b that is a central portion that connects both sides of the H-shape. Yes. The movable part 22 has a tongue deformation at a part of the rear side of both sides of the H-shape.

  As shown in FIG. 2, the fixed portion 21 and the movable portion 22 of the support base 2 are rotatably connected by a rotation shaft 4 that protrudes from the main body portion 21 b of the fixed portion 21 and is inserted into the movable portion 22. . That is, the movable portion 22 and the rotation shaft 4 constitute a variable shape structure that can change the shape of the support base 2. The rotation range of the movable part 22 is vertical (state shown in FIG. 1 (B)) standing upright from the horizontal (state shown in FIG. 1 (A)) in contact with the table surface F by a stopper or the like not shown. ).

  About the rotation of the movable part 22 of the support stand 2, the lock mechanism 5 can be locked at an arbitrary rotation position. As shown in detail in FIGS. 2 and 3, the lock mechanism 5 includes a slide groove 51 digged into the main body portion 21 b of the fixing portion 21 and a rotation shaft 4 connected to the inside of the slide groove 51. Provided on the slider 52 slidable in the axial direction of the moving shaft 4, a coil spring 53 accommodated in the slide groove 51 for repressing the slider 52 toward the movable portion 22, and a surface of the slider 52 facing the movable portion 22. The ring-shaped friction disc 54 in which the fine irregularities thus formed are continuous radially and the ring-shaped friction receiving plate 55 in which the fine irregularities provided on the movable part 22 are opposed to the friction disc 54 in a radial manner. . The rotating shaft 4 penetrates the movable portion 22 and protrudes to the outside, and also serves as an operation portion that slides the slider 52 of the lock mechanism 5.

  Further, the rotation of the movable portion 22 of the support base 2 is urged by the urging mechanism 6 in the direction in which the movable portion 22 is brought into contact with the table surface F. As shown in detail in FIGS. 2 and 3, the urging mechanism 6 includes a torsion coil spring that is stretched between the main body portion 21 b of the fixed portion 21 and the movable portion 22 around the rotation shaft 4. .

  The stand 3 is formed in a cylindrical shape, and is erected at the center of the main body portion 21 b of the fixing portion 21 of the support base 2.

  According to the first example, the movable portion 22 of the support base 2 is integrated with the fixed portion 21, and the rotation shaft 4 is built in the support base 2 and only a part is exposed and protrudes. Since the shape variable structure is not exposed and protruded greatly from the support base 2 unlike the auxiliary support base of the thin display device according to Patent Document 1, the design is improved.

  In the desktop installation of the first example, as shown in FIG. 1A, the fixed portion 21 and the movable portion 22 of the support base 2 are brought into contact with the table surface F integrally. Therefore, a large contact area with the table surface F of the support base 2 is ensured, and the stability of the tabletop installation is enhanced. In addition, in the desktop installation, the state of the movable portion 22 of the support base 2 is locked and urged by the lock mechanism 5 (contact (meshing) of the friction disk 54 and friction receiving board 55) and the urging mechanism 6. The movable part 22 of the support base 2 does not operate unexpectedly and does not impair the stability.

  When converting the first example from the desktop installation to the wall-mounted installation, the rotary shaft 4 is pressed to slide the slider 52 of the lock mechanism 5 inward against the spring force of the coil spring 53, and the friction disc 54, The contact of the friction receiving plate 55 is released, and the movable portion 22 of the support base 2 is rotated about the rotation shaft 4 against the elastic force of the urging mechanism 6.

  In the wall-mounted installation of the first example, as shown in FIG. 1 (B), the movable portion 22 of the support base 2 stands upright to the front side (fixed portion 21 side). Accordingly, the protrusion of the support base 2 toward the rear side of the display unit 1 and the stand 3 is reduced to the maximum. As a result, as shown in FIG. 1C, the stand 3 can be easily and surely attached by being inserted into a fixture A such as a hook attached to the wall surface W. In addition, in the wall-mounted installation, since the state of the movable part 22 of the support base 2 is locked by the lock mechanism 5, the movable part 22 of the support base 2 operates unexpectedly to press the wall surface W, and the stand 3 is attached to the fixture. There will be no accidental withdrawal from A.

  Further, in the wall-mounted installation, as shown in FIG. 4, if the movable portion 22 of the support base 2 is rotated in the reverse direction and brought into contact with the wall surface W on both sides of the stand 3 and the fixture A, the fixture A The wobbling on the wall surface W at the three points to which is added can prevent the entire wobble and stabilize the wall hanging installation.

  In the case of converting the first example from wall-mounted installation to desktop installation, the stand 3 is removed from the fixture A attached to the wall surface W, the support base 2 is placed on the table surface F, and the rotating shaft 4 is pressed. The movable portion 22 of the support base 2 can be automatically returned to the state shown in FIG. Therefore, the conversion operation from the wall-mounted installation to the desktop installation is easy.

  5 to 7 show a second example of the best mode for carrying out the thin display device according to the present invention.

  In the second example, as shown in FIGS. 6 and 7, the planar shape of the support base 2 is formed in a trapezoidal shape, the narrow portion on the rear side is a movable portion 22, and the fixed portion 21 and the movable portion 22 are L-shaped. Are coupled by a rotating shaft 4 so as to be rotatable. The rotating shaft 4 does not protrude from the movable portion 22 of the support base 2. Further, the rotation range of the movable portion 22 of the support base 2 is not different from the first example described above. Further, the urging mechanism 6 is basically not different from the first example described above.

  The lock mechanism 7 of the second example includes two lock pieces 71 that can contact both the fixed portion 21 and the movable portion 22 of the support base 2, and the upper surface of the fixed portion 21 of the support base 2. , A support shaft 72 that supports the lock piece 7 so as to be able to disengage from the movable portion 22, a link shaft 73 that interlocks the operations of the lock pieces 71, and each support shaft 72. A link arm 74 that connects the shaft 73 and a coil spring 75 that is connected to the link shaft 73 so as to be pulled and biases the lock piece 71 in the direction of contact with both the fixed portion 21 and the movable portion 22 of the support base 2. And a lock groove 76 into which the leading end portion of the lock piece 71 is inserted and locked into the movable portion 22 which is dug into the movable portion 22 of the support base 2 and stands upright. The support shaft 72, the link shaft 73, and the link arm 74 are accommodated inside the fixed portion 21 of the support base 2.

  According to the second example, the movable portion 22 of the support base 2 is integrated with the fixed portion 21, the rotating shaft 4 is built in the support base 2, and the lock piece 71 and the lock groove 76 of the lock mechanism 7 are exposed and protruded. Therefore, the shape variable structure of the support base 2 is not significantly exposed and protruded from the support base 2 unlike the auxiliary support base of the thin display device according to Patent Document 1, and the design is good.

  In the desktop installation of the second example, as shown in FIG. 5A, the fixed portion 21 and the movable portion 22 of the support base 2 are brought into contact with the table surface F integrally. Therefore, a large contact area with the table surface F of the support base 2 is ensured, and the stability of the tabletop installation is enhanced. In the desktop installation, the state of the movable portion 22 of the support base 2 is locked by the lock mechanism 7 (the locking piece 71 is in contact with both the fixed portion 21 and the movable portion 22 of the support base 2) and the biasing mechanism 6. Since it is energized, the movable part 22 of the support base 2 does not operate unexpectedly and does not impair the stability.

  When converting the second example from the desktop installation to the wall-mounted installation, the lock piece 71 of the lock mechanism 7 is rotated against the tension of the coil spring 75 and the lock piece 71 is moved to the movable portion 22 of the support 2. After the contact is released (see FIG. 6), the movable portion 22 of the support base 2 is rotated about the rotation shaft 4 against the elastic force of the urging mechanism 6, and then the lock piece of the lock mechanism 7 is locked. 71 is restored to its original state by pulling the coil spring 75 (see FIG. 7).

  In the wall-mounted installation of the second example, the stand 3 can be easily and reliably attached from the state shown in FIG. 5B by inserting the stand 3 into a fixture A such as a hook attached to the wall surface W. Functions and effects similar to those of the first example are exhibited. However, the lock mechanism 7 is a mechanism in which the lock piece 71 is engaged with a lock groove 76 provided in the movable portion 22 where the support base 2 stands up to lock the rotation of the movable portion 22. It does not lock in the pivot position. In addition, when the second example is converted from wall-mounted installation to table-top installation, the same operations and effects as the first example described above are exhibited.

  As described above, in addition to the illustrated examples, it is possible to rotate the movable portion 22 of the support base 2 to the position where the movable portion 22 is folded to the fixed portion 21.

  Furthermore, the present invention can be applied not only to wall-mounted installation but also to wall-mounted installation.

Further, the lock piece 71 of the lock mechanism 7 can be accommodated in the support base 2.
