Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flat display device, and more particularly to a mechanism for attaching the flat display device to a ceiling or a wall.
[0002]
[Prior art]
The flat display device is generally configured as described in FIG. FIG. 6 is a perspective view showing a conventional flat display device. In FIG. 6, the flat display device 50 has a display unit 51 having a function of displaying a desired image, and for holding the display unit 51 at a predetermined height when the flat display device 50 is disposed on the floor surface 56. And a stand 52.
[0003]
The display unit 51 uses a display whose length (that is, thickness) in a direction perpendicular to the display screen is smaller than that of a CRT (cathode ray tube) display, such as a liquid crystal display or a plasma display. These include organic EL (electroluminescence) displays, inorganic EL displays, and the like.
[0004]
Since such a flat display device 50 is lighter than a CRT, the flat display device 50 can be arranged without any special reinforcement on a surface other than the floor surface such as a wall or a ceiling, and since the display portion is flat, it can be arranged from the wall or ceiling. The protruding amount can be kept small. Therefore, there are cases in which viewing is performed by placing them on a wall or ceiling. At this time, there are mainly the following two methods for arranging the flat display device 50 on a surface other than the floor surface 56.
[0005]
One is that, as shown in the perspective view of FIG. 7, a hole is made in the stand 52, a bolt is passed through the hole, and then a surface other than the floor surface 56 (the ceiling 13 in FIG. 7) is provided in advance. The bolt 53 is fastened to a placed nut, and the stand 52 is fixed to a surface other than the floor surface 56.
[0006]
As shown in the perspective view of FIG. 8, the other one uses a dedicated placement tool 54 for removing the stand 52 and fixing it to a surface other than the floor surface 56. For example, one having a fixed end 54 a for fixing the flat display device to a surface other than the floor surface 56 with a screw 55 and a free end holding the flat display device 50 is used. As an example of taking such an arrangement method, Patent Document 1 describes a device including a suspension mechanism that is attached in a state where the flat display device is suspended.

[0011]
The “locking tool for attaching the lighting device” referred to herein means that a certain amount of load is supported by locking the locked tool in the locking tool, and the contact between the locking tool and the locked tool. For example, what is called a hook ceiling (see Japanese Patent Application Laid-Open No. 9-219110) or a sealing fitting is applicable.
[0012]
In addition, the conventional CRT was significantly heavier than the lighting device, so it was impossible to hold it other than the floor using the “locking tool for attaching the lighting device”, but the flat display device was lightweight. Therefore, if the size is not more than the predetermined size, a display device having a weight limit or less that can be held by the “locking tool for attaching the lighting device” can be manufactured.
[0013]
In the present invention, in the flat display device including a flat display unit having a function of displaying an image and a stand for arranging the flat display unit on a floor surface, the display of the stand A locking tool that can be engaged with a locking tool for attaching the lighting device is provided on the end surface opposite to the end provided with the portion, and the locking tool is disposed at a predetermined position in the room.

It is possible to ensure strength and supply power, and to arrange on the floor and other places with the same configuration.
[0015]
By the way, a flat display device generally has a heavy display section. Therefore, when the bottom surface of the stand is separated from the indoor surface where the locking device is disposed, a moment is applied to the place fixed by the locking device and the locked device, and in some cases, the locked surface is locked. The tool may be damaged.
[0016]
Therefore, in a state where the locking tool and the locked tool are engaged, the surface on which the locking tool is disposed and the end surface of the stand on the side opposite to the end provided with the display portion. The flat display device is characterized by comprising adjusting means for adjusting the distance, and the adjusting means is adjustable up to a position where the surface and the stand abut.
[0017]
According to this configuration, when the flat display device is disposed so that the stand is horizontal, the moment is adjusted by the bottom surface of the stand by adjusting the surface on which the locking tool is disposed and the bottom surface of the stand to contact each other. Since it can receive, it becomes possible to arrange stably.
[0018]
The flat display device that enables this stable arrangement is more preferably a rotating means that rotates the locked tool while the locking tool is mounted on the locked tool. And an adjusting means that is provided separately from the rotating means, can adjust the distance between the locked tool and the surface on which the locking tool is disposed, and does not rotate when the rotating means is rotated, And an urging unit that urges the locked tool in a direction away from the surface and moves the flat display device to the surface side by the urging force.
[0019]
According to this configuration, after the locked tool is mounted on the locking tool, the biasing means can perform the operation of bringing the surface on which the locking tool is disposed into contact with the bottom surface of the stand. Can be done.
[0020]
In any of the above flat display devices, the flat display device can be arranged at a predetermined position in the room by mounting the locking tool and the locked tool. In many cases, information to be displayed on the display device is transmitted from the outside. Therefore, if a wireless reception device that wirelessly receives signals transmitted from other devices is provided, it is not necessary to connect a wiring for reception, and the arrangement is further facilitated.
[0021]

(Embodiment 3)
Further improvements can be added to the first embodiment. An example with this improvement will be described as a third embodiment with reference to FIGS.
[0033]
First, the background of the invention according to the third embodiment will be described. A locking tool for attaching a lighting device is provided with insertion ports 16 and 16 from an indoor surface (for example, the ceiling 13) on which the locking tool is disposed. The distance to the surface is not constant. Therefore, when the locked tool 11 is engaged with the locking tool 14, the bottom surface 23 of the flat display device 20 may be disposed apart from the ceiling 13.
[0034]
On the other hand, the flat display device 20 is generally heavier on the screen 18 arrangement side than on the back side because the screen 18 is heavy. Therefore, when the flat display device 20 is disposed on the ceiling 13, a moment is applied in a direction in which the center of gravity of the flat display device 20 is directed vertically downward of the engagement portion between the locking tool 14 and the locked tool 11. . When such a moment is generated, an unexpected force is applied to the contacts 12, 12, which may cause a problem in strength.
[0035]
Therefore, for example, as shown in FIG. 3, the bottom surface 23 contacts the ceiling 13, so that the moment generated from the weight balance problem is received by the contact between the bottom surface 23 and the ceiling 13, and the contact 12. , 12 is to solve the strength problem.
[0036]
FIG. 3 is a cross-sectional view of a flat display device 40 provided with the solution. The description of the third embodiment will be made with reference to FIG. In addition, about the structure same as Embodiment 1, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.
[0037]
3, in addition to the configuration described in the first embodiment, the stand 22 includes a biasing unit 26 that biases the locked tool 11 having the contacts 12 and 12 toward the display unit 21 (not shown). The locked tool 11 is formed to be movable toward the opening side of the hole 10 against the biasing force of the biasing means 26, and the distance between the locked tool 11 and the surface on which the locking tool 14 is arranged can be adjusted. An adjusting means 27 and a rotating means 28 for rotating the locked tool 11 when the locked tool 11 is inserted into the locking tool 14 are provided.
[0038]
To describe each configuration in detail, the shape of the hole 10 is such that the flange 10b extends from the periphery of the opening of the bottomed cylindrical hole toward the center side of the cylindrical hole, whereby the outer diameter of the opening Is narrower than other parts.
[0039]
The biasing means 26 is attached so that the flange 10b becomes a fixed end, and a known elastic body such as a coil spring or a leaf spring is used. The urging force of the urging means 26 is sufficient to move the entire flat display device 40, and the surface 11 b on the display unit side of the locked tool 11 contacts the bottom surface 10 c of the hole 10 when no external force is applied. It is the contact length. Further, a contact body 29 that contacts the locked tool 11 is disposed at the end of the biasing means 26 opposite to the end of the flange 10b side. The abutting surface is formed as a smooth surface where frictional force is difficult to work.
[0040]
The locked tool 11 is formed in a disk shape having an outer periphery that is substantially the same as the inner periphery of the hole 10, and the contact body 29 is in contact with the vicinity of the outer periphery. Further, a rotating means 28 for rotating the locked tool 11 is extended from the surface 11 b on the display unit side of the locked tool 11.
[0041]
In the rotating means 28, one end of a rod-shaped body is joined to the locked tool 11, and the other end is formed with a knob-shaped portion 34 that is easily gripped by hand. The rod-shaped body 36 between one end and the other end includes a screw hole 35 penetrating from the surface 37 facing the bottom surface 23 of the stand 22 to the bottom surface 10 c of the hole 10, and a female screw provided in the screw hole 35. Are arranged to penetrate without screwing.
[0042]
And the adjustment means 27 which adjusts the distance of the to-be-latched tool 11 and the surface where the securing tool 14 is arrange | positioned so that the circumference | surroundings of a radial direction may be covered with respect to the rod-shaped body 36 and the knob-shaped part 34 of the rotation means 28. Is placed.
[0043]
The adjusting means 27 is fitted in such a manner that when one of the adjusting means 27 and the rotating means 28 is rotated, the other is not rotated, and the outer periphery of the portion facing the outer periphery of the rod-shaped body 36 is disposed in the screw hole 35. A male screw is formed to be screwed with the female screw. The above is the details of each configuration.
[0044]
Next, using these, the locked tool 14 is attached to the locking tool 11, and then the position of the flat display device 40 is adjusted so that the bottom surface of the flat display device 40 comes into contact with the surface on which the locking tool 11 is disposed. The operation at that time will be described.
[0045]
First, as shown in FIG. 4, the adjusting means 27 is rotated before the contacts 12, 12 of the locked tool 14 are inserted into the insertion ports 16, 16 of the locking tool 11, and the biasing means 26 is most contracted. To. At this time, the to-be-latched tool 11 receives a force more than the level that can move the flat display device 40 to the surface on which the latching tool 11 is disposed by the biasing means 26.
[0046]
Then, the contacts 12 and 12 of the locked tool 14 are inserted into the insertion ports 16 and 16 of the locking tool 11 and the rotating means 28 is rotated. When the rotation means 28 is rotated, the locked tool 11 rotates while abutting against the nodal body 29, the contacts 12, 12 move to a predetermined position in the lock tool 11, and the contact point of the locked tool 11. Join with. At this time, the locked tool 11 still receives the urging force of the urging means 26.
[0047]
In this state, the adjusting means 27 is rotated in the direction in which the urging means 26 extends. Then, the flat display device 40 gradually moves in the direction of the surface on which the locking tool 14 is arranged by the urging force of the urging means 27. Further, when the adjusting means 27 is rotated in the direction in which the urging means 26 extends, at the time when the adjusting means 27 is rotated to some extent, the bottom surface 23 of the flat display device 40 is arranged with the locking tool 11 as shown in FIG. It will be in contact with the surface.
[0048]
In this way, even when the center of gravity of the flat display device 40 is not vertically below the locked tool 14 due to the flat display device 40 and the surface on which the locking tool 11 is disposed contacting, Since the moment generated by the deviation of the center of gravity is received by the entire bottom surface 23, the flat display device 40 can be stably held.
