Description

The present invention relates to a display device using a flat display panel, and more particularly to a display device that has been improved to allow the display device to be installed at at least two positions such as a desktop or a wall surface depending on the application.

  In recent years, in consumer display devices such as televisions, display devices using flat display panels such as plasma display panels (PDP) and liquid crystal displays (LCD) (hereinafter sometimes referred to as “thin display devices”). Is becoming mainstream. Thin display devices are thinner than conventional CRT televisions, so that they are used not only for installation on a TV stand or the like (desktop) for viewing but also for viewing on a wall. When installing a thin display device on a desktop, a desktop support device called a “table stand” is attached to the thin display device main body. Further, when installing a thin display device on a wall, a wall-mounted support device called a “wall-mounting bracket” is attached to the thin display device body. In other words, the support device is attached to the thin display device main body by selecting either a table stand or a wall-hanging bracket according to the user's application.

  In general, when a user purchases a thin display device, the user selects either a table stand or a wall hanging bracket. For this reason, when the installation mode is changed from a state where it is installed on a table, for example, to a state where it is hung on a wall surface, it is necessary to purchase a wall hanging bracket separately, which places an economical burden on the user.

  Therefore, a support device having a structure that can be installed on a wall or a table with one support device as described in Patent Document 1 has been proposed. This is a structure in which a column is pivotally attached to a thin display device main body, and can be installed on a wall or on a table by changing the direction of the column and base plate.

JP 2003-263116 A

  The thin display device shown in Example 1 of Patent Document 1 has a structure in which the support column of the support device is held by the exterior portion (front frame) of the thin display device body. The exterior portion usually has many members that place importance on design, and often has lower strength than members that support the structure inside. For this reason, when applied to a thin display device having a large screen, if the weight of the thin display device body is large, the exterior portion may be deformed by a load applied to the holding portion, and the appearance may be impaired.

  In addition, design is emphasized in the thin display device, and it is not preferable in terms of design that a part other than the thin display device body is conspicuous when viewing. In the first embodiment of Patent Document 1, consideration is not given to making the support device inconspicuous, and a part of the support device such as a support column becomes conspicuous during viewing.

  In order to avoid the above problem, a method is conceivable in which a protrusion is provided on the back surface side of the thin display device main body and the support column of the support device is held by the protrusion as in the second embodiment of Patent Document 1.

  In the thin display device described in Example 2 of Patent Document 1, the thin display device main body is fixed only by a screw serving as a pivot center of the support column. Therefore, there is a problem that when the screw is loosened during use, the thin display device body moves. Also, if the screw is used for a long time with the screw loosened, the screw may eventually come off and the thin display device body may fall and be damaged. In order to prevent the screws from loosening, there is a method of fixing the screws with an anti-loosening agent such as an adhesive. However, in that case, it becomes difficult to change the installation form from desktop installation to wall mounting.

  Further, in the above thin display device, since the contact area between the support column and the thin display device main body is close, it is difficult to cope with a large screen with a large weight.

  The present invention has been made in view of the above problems, and can firmly support a heavy, large-screen thin display device body, and the thin display device can be installed in two ways: desktop installation or wall surface installation. Furthermore, the present invention provides a technique that minimizes the exposure of members other than the thin display device main body.

  In the thin display device of the present invention, a chassis is disposed on the back side of the flat display panel, a fixing member is coupled to the chassis, and one end side of the support column is connected to the fixing member by a link, and can be rotated. A base plate is rotatably connected to the other end of the support column. In addition, when a fixing member different from the fixing member is attached to the chassis and the base plate is used as a stand when the display device is placed on a table, the column is attached to the fixing member and another fixing member, for example, a screw or the like. You may make it fix by. When the display device is installed on the wall, the base plate is hidden behind the display device by moving the support column and rotating the base plate.

  According to the present invention, it is possible to firmly support a thin display device body whose weight is increased by increasing the screen size.

  In addition, since the support and the base plate have a movable structure, it is possible to easily install the apparatus on the desktop and the wall without changing the support device.

  Further, when the support device is changed from the desktop type to the wall-mounted type, the base plate moves to the back surface of the thin display device, so that members other than the thin display device main body become inconspicuous in the wall-mounted state.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  A first embodiment of the present invention will be described with reference to the drawings, taking as an example a thin display device when the flat display panel is a PDP. 1 and 2 are perspective views showing a state in which a thin display device according to Embodiment 1 of the present invention is installed on a table of a television stand or the like (not shown), and FIG. 1 is a view as seen from the display surface side. 2 is a view from the back side.

  When the thin display device is installed on a table, the column 8 is fixed to the base plate 7 with the base plate fixing screws 15 and the table-type fixing screw holes 20 as shown in FIG. Thereby, since the support | pillar 8 is fixed in the position perpendicular | vertical to the baseplate 8, it becomes possible to arrange | position a thin display apparatus on the table | surface 28.

  As described above, members such as the flat panel display 1, the front frame 2, and the back cover 3 are also held by the highly rigid chassis 4, and the support device 31 is also highly rigid via the fixing member A 5 and the fixing member B 6. Fixed to the chassis 4. Thereby, even when the weight increases due to the large screen, the thin display device body 30 can be firmly supported.

  8 and 9 are perspective views showing a state in which the thin display device according to the first embodiment of the present invention is installed on the wall surface of a wall or the like (not shown), and FIG. 8 is a view as seen from the display surface side. These are the figures seen from the back side.

  When the thin display device is mounted on the wall, as shown in FIGS. 9 and 10, the column 8 is arranged at the upper position, and the column fixing screw 14 is used by the column fixing screw hole B 17 and the column fixing screw hole C 18. The fixing member A5 and the fixing member B6 are fixed. At this time, the column fixing screw hole A16 used for fixing the column 8 and the fixing member A5 at the time of desktop placement is used for fixing to the wall surface. 9 and 10, the fixing member A5 and the fixing member B6 coupled to the chassis and the link 9 are exposed from the back cover 3.

Further, the base plate 7 is rotated 90 degrees from the desktop arrangement state, and the base plate fixing screw 15 as shown in FIG. 9 is fixed to the column 8 by the wall-hanging type fixing screw hole 21 of the base plate 7. Thereby, the support column 8 and the base plate 7 are in a parallel positional relationship.
By fixing as described above, the base plate 7 and the support column 8 can be hidden behind the thin display device body 30.

A mechanism for changing the form of the support device 31 from the desktop type to the wall-mounted type will be described with reference to FIG. FIG. 10 is a side view showing the mechanism when changing from the desktop arrangement to the wall-mounted arrangement setting.
First, the column fixing screw 14 for fixing the column 8 and the fixing member A5 and the fixing member B6 and the base plate fixing screw 15 for fixing the column 8 and the base plate 7 are removed from the desktop arrangement.
Next, the link 9 is rotated as indicated by an arrow A in FIG. 10 to move the support column 8 upward. At the same time, as shown by arrow B, the base plate 7 is rotated so that the base plate 7 comes to the back of the thin display device main body 30. Finally, the support column 8 and the fixing member A5 and the fixing member B6 moved upward are fixed by a column fixing screw 14, and the base plate 7 and the column A8 are fixed by a base plate fixing screw 15, respectively.

  At this time, as shown in FIG. 10, the portion of the column 8 where the column fixing hole B is provided is received by being fitted into the recess of the fixing member A5, and further fixed by screws. As described above, in this embodiment, the support column 8 can be rotated by the link 9 while being shifted in the vertical direction (in the vertical direction of the thin display device) between the desktop arrangement and the wall-mounted arrangement. For this reason, the position of the column 8 fixed by the fixing members A5 and B6 at the time of wall mounting can be configured to be shifted upward from the position of the column 8 fixed by the fixing members A5 and B6 at the time of tabletop arrangement. As a result, the lower end portion of the support column 8 was exposed below the front frame 2 when the thin display device was viewed from the front surface (display surface) when placed on the desktop, but the exposed support column when mounted on the wall. It is possible to prevent the lower end portion of 8 from being exposed from the lower end of the front frame 2.

  In any case, the dimensions of the column 8 are set so that the upper end of the column 8 is not exposed from the upper end of the front frame 2 when the thin display device is viewed from the front surface (display surface).

  Therefore, according to the present embodiment, it is possible to prevent the appearance of the thin display device from being damaged by the support device including the support column 8 especially when the wall is hung.

  Further, the base plate 7 is moved to the back side of the back cover 3 so as to be accommodated between the two support columns 8 when being mounted on the wall. Accordingly, since the thickness of the entire thin display device including the support device is increased only by the thickness of the support column 8 when hanging on the wall, both the desktop arrangement and the wall hanging arrangement can be achieved without significantly increasing the thickness of the thin display apparatus. be able to.

  As described above, the usage form of the thin display device can be easily changed from the desktop arrangement to the wall-mounted arrangement. When changing from a wall-mounted arrangement to a desktop arrangement, the procedure may be reversed.

  FIG. 11 is a diagram showing a state in which the thin display device is fixed to the wall. Reference numeral 23 is a wall surface fixing screw, and 29 is a wall surface. By passing the wall surface fixing screw 23 through the column fixing screw hole A16 of the column 8 and fixing it to the wall surface 29, it becomes possible to install the thin display device on the wall.

Then, it fixes to fixing member B6 with the support | pillar fixing screw 14.

  Further, since the base plate 7 is the same as that of the first embodiment, the description thereof is omitted.

  Then, in the case of a wall-mounted arrangement, after the base plate 7 is rotated 90 degrees and then fixed with the base plate fixing screw 15, the column B24 is slid upward, and the column fixing screw hole B17 is By fixing to the fixing member C28 with the fixing screw 14 and fixing to the fixing member B6 with the column fixing screw 14 at the column fixing screw hole C18, it is possible to change to a support device for wall hanging arrangement as in the first embodiment. .

  In the second embodiment, the fixing member C28 has a concave shape, and is configured such that the column B24 is housed both when placed on a table and when placed on a wall, as in the first embodiment. As in the first embodiment, the column B24 can be shifted (slid) in the vertical direction (in the vertical direction of the thin display device) between the desktop arrangement and the wall-mounted arrangement. For this reason, the position of the column B24 fixed by the fixing members C28 and B6 at the time of wall mounting can be configured to be shifted above the position of the column B24 fixed by the fixing members C28 and B6 at the time of tabletop arrangement. As a result, similarly to the above, it is possible to prevent the lower end portion of the column B24 from being exposed from the lower end of the front frame 2 when hanging on the wall. Naturally, the dimensions of the column 8 are set so that the upper end of the column 8 is not exposed from the upper end of the front frame 2.

  Therefore, also in the present embodiment, it is possible to prevent the appearance of the thin display device from being damaged by the support device including the support column 8 when hanging on the wall.

  Further, as in the first embodiment, the base plate 7 is moved to the back side of the back cover 3 so as to be accommodated between the two support columns 8 in the wall-mounted arrangement. Accordingly, since the thickness of the entire thin display device including the support device is increased only by the thickness of the support column 8 when hanging on the wall, both the desktop arrangement and the wall hanging arrangement can be achieved without significantly increasing the thickness of the thin display apparatus. be able to.

  As described above, in the thin display device equipped with the second embodiment of the present invention, as in the first embodiment, the column B24 and the fixing member C28 are connected by the column slide screw 25 and the nut 26.
