SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and can be installed in a narrow space without deteriorating the advantage of the thinness of a flat display device, and can adjust the installation height of the display device. An object of the present invention is to provide a lifting device for a flat display device which can be easily performed.

[0004]

In order to solve the above-mentioned problems, the present invention is to form a U-shape, project a shaft at the center of the back surface, and provide holes on both the left and right sides, and the shaft. The display device has a rotating plate provided with pins on one side and a horizontally-long hole provided with the pins sliding on a back plate, and the support base has a rotatable support. And a stopper for locking the rotation of the shaft.

[0005]

With the above construction, in the lifting device for a flat panel display device according to the present invention, the height of the display device may be increased if the display unit is difficult to see due to reflected light or the like, or if the viewer's posture changes. If you want to change the screen, you can do it with an easy operation, and also respond to significant changes in posture, such as watching the viewer standing or sitting, by changing the installation height of the screen It is possible to provide a lifting device for a display device which can be installed even if the installation space is small, and which does not impair the thinness of the flat display device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view of an embodiment of a lifting / lowering device for a flat panel display according to the present invention, and FIG. 2 is a sectional view taken along line AA of FIG. In FIG. 1, the display device 2
Is a liquid crystal display device or a thin flat panel display device of a PDP. The stand 1 has a flat base 1a at the bottom, and a support 1b of the display device is placed on the base 1a. The support base 1b is a U-shaped support base having an open front surface when viewed from the top, and has vertically elongated holes 1c formed on both sides. A cylindrical pin 4 having a disc-shaped flange 4a on one side is fitted and fixed at the center of the support 1b at the other end into a hole 1d provided in the support 1b. The disk-shaped rotary plate 3 is locked by the flange 4a, and is rotatably supported by the pin 4. The rotating plate 3 has an uneven portion 3a on the circumference.
Left and right sides thereof are projected from the holes 1c on both sides of the support base 1b, and a support pin 5 of a display device having a flange 5a at a tip is fitted into a side of the rotary plate 3 where the support base is open. Fixed.

The flat display device 2 has a horizontal rectangular hole 2b formed in a rear plate 2a, and the support pin 5 of the rotary plate 3 is engaged with the flange 5a in the hole 2b.
While the display device 2 is supported, the support pin 5 is slidably fitted over the hole 2c. Further, a plurality of rectangular slides 6 made of urethane material are protrudingly provided on both side surfaces of the display device 2, and the slide 6 slides inside the both side surfaces of the support base 1b, so that the display device 2 The support base 1b is slidable up and down. A rectangular hole 1e is formed in the center of the lower part of the support base 1b.
A pin 8 is stretched in the left-right direction at a central portion, and a stopper 7 is rotatably supported by inserting the pin 8 into a hole 7a provided at the central portion. The stopper 7 has a key shape, and the tip of the key portion has an acute angle portion formed in the longitudinal direction, and the acute angle portion meshes with the circumferential unevenness of the rotating plate 3 so that the rotating plate 3 is engaged. It is designed to lock. The other end of the stopper 7 is exposed on the back side of the support 1b, and the other end and the base 1 of the support 1b.
A spring 9 having a tensile force is stretched between them, and a rotational force is generated in the stopper 7 by the tensile force of the spring 9, and the acute angle portion at the tip is pressed against the rotating plate.

Next, the operation of the above configuration will be described. When a portion of the rotating plate 3 protruding from both side surfaces of the support base is manually operated in a vertical direction to apply a rotating force to the rotating plate 3, the tip of the stopper 7 slides on the uneven surface of the rotating plate. , The rotating plate 3 rotates. Accordingly, the support pins 5 fitted on the rotating plate and supporting the display device also rotate, and when the support pins 5 slide on the horizontal rectangular holes 2b provided in the display device back plate 2a, the support The rotational movement of the pin 5 is converted into a vertical movement, whereby the display device 2 slides up and down by the slide 6 being guided inside the side surface of the support base 1b.

When the rotary plate 3 is stopped at an arbitrary position, the tip end of the stopper 7 meshes with the irregularities 3a on the circumference of the rotary plate 3 again, whereby the rotary plate 3 is fixed and The display device 2 is also fixed at an arbitrary height position.

[0010]

As described above, in the elevating device for the flat display device according to the present invention, the display device is difficult to see due to reflected light or the like, or the display device is changed due to a change in the attitude of the viewer. When it is desired to change the installation height of the display device, it is possible to easily change the position of the display device and fix the display device at an arbitrary position by rotating the rotary plate on the side surface of the stand. Further, the stand can be configured as a lifting device for a thin display device, which does not impair the advantage of the flat display device being thin.
