Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly to a lifting device for a flat display device.

[0002]

2. Description of the Related Art A stand for a flat panel display device such as a liquid crystal display device or a plasma vision display device (hereinafter referred to as a PDP device) has a rotation support portion 11 on the back surface of the display device 10 as shown in FIG. An arm 12 provided with the display device 10 rotatably and pivotally supporting the display device 10 and a rotation support portion 11 provided on a base 13.
Was supported by. When it is difficult to see the screen of the display device due to reflected light or when it is desired to change the screen position due to changes in the posture of the viewer, the rotation support portion 11 is rotated to set the display device at an arbitrary angle. There is a limit to adjustment by only changing the angle, and there is a need for a support base that has a wide adjustment range and that can easily change the installation height of the display device that can be viewed by the viewer standing or sitting. It was

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 impairing the advantages of the flat panel display device, and the height of the display device can be adjusted. An elevator device for a flat panel display device that can be easily performed.

[0004]

In order to solve the above-mentioned problems, the present invention has a support base formed in a U-shape, a shaft protruding from the center of the back surface, and holes on both left and right sides, and the shaft. Rotatably supported on both sides, the left and right sides project from the hole, and the display plate and the support base are provided with a rotating plate having a pin on one side and a horizontally elongated hole on the back plate for sliding the pin. It is characterized by being configured with a stopper that locks and rotates the shaft.

[0005]

With the above-described structure, in the elevating device for a flat panel display device according to the present invention, the height of the display device is increased when the display portion is difficult to see due to reflected light or when the posture of the viewer changes. If you want to change it, you can do it with an easy operation, and change the screen installation height to respond to a large change in posture such as when the viewer stands or looks while sitting. It is possible to provide an elevating device for a display device that can be installed even if the installation space is small and does not impair the advantages of the flat display device being thin.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a front view of an embodiment of a lifting device for a flat panel display device according to the present invention, and FIG. 2 is a sectional view taken along line AA. In FIG. 1, the display device 2
Is a liquid crystal display device or a thin flat panel display device of PDP. The bottom of the stand 1 is composed of a flat plate-shaped base 1a, and a support base 1b of the display device is placed on the base 1a. The support base 1b is a U-shaped support base whose front portion is open when viewed from the top surface direction, and vertically long holes 1c are formed on both sides. Further, a cylindrical pin 4 having a disk-shaped flange 4a on one side is fitted and fixed at the other end into a hole 1d provided in the support 1b at the center of 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 its circumference.
The left and right sides of the support 1b are projected from the holes 1c on both sides of the support 1b, and the support pin 5 of the display device having the flange 5a at the tip is fitted in the side surface of the rotation plate 3 where the support is open. It is fixed.

In the flat panel display device 2, a rear plate 2a is formed with a horizontal rectangular hole 2b, and the support pin 5 of the rotary plate 3 is locked to the flange 5a by the hole 2b.
The display device 2 is supported, while the support pin 5 is slidably fitted over the hole 2c. A plurality of rectangular slides 6 made of urethane material are provided on both side surfaces of the display device 2 in a protruding manner. The slides 6 slide on the insides of both side surfaces of the support base 1b. The support 1b is slidable up and down. A rectangular hole 1e is formed in the center of the lower portion of the support base 1b.
A pin 8 is stretched in the left-right direction in the central portion of the, and a stopper 7 is rotatably supported by inserting the pin 8 into a hole 7a provided in the central portion. The stopper 7 has a key shape, and an acute angle portion is formed in the longitudinal direction at the tip of the key portion. It is designed to be locked. The other end of the stopper 7 is exposed on the back surface 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 and, and the tensile force of the spring 9 causes a rotational force to the stopper 7, so that the acute angle portion of the tip is pressed against the rotary plate.

With the above configuration, the operation will be described below. When the portions of the rotary plate 3 projecting from both sides of the support base are manually moved in the vertical direction and a rotational force is applied to the rotary plate 3, the tip of the stopper 7 slides on the uneven surface of the rotary plate. The rotary plate 3 rotates. Along with this, the support pin 5 fitted on the rotary plate and supporting the display device also rotates, and when the support pin 5 slides on the horizontal rectangular hole 2b provided in the display device rear plate 2a, the support pin 5 is supported. 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 1b.

When the rotary plate 3 is stopped at an arbitrary position, the tip of the stopper 7 is re-engaged with the circumferential unevenness 3a of the rotary plate 3, thereby fixing the rotary plate 3 and The display device 2 is also fixed at an arbitrary height position.

[0010]

As described above, in the elevating and lowering device of the flat panel 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 changes in the posture of the viewer. When it is desired to change the installation height of the stand, the position of the display device can be easily changed and fixed at an arbitrary position by rotating the rotary plate on the side surface of the stand. In addition, the stand can be configured as an elevating device for a thin display device without structurally deteriorating the advantage of a thin flat display device.
