Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary base for rotating a screen of a television having a large image display surface, and more particularly to a mechanism of a TV screen rotary base suitable for use in multivision.

[0002]

2. Description of the Related Art Televisions and multi-visions with large screens are often installed in showrooms, etc., and the screens show the stage status in the showroom near the entrance or external conditions in the showroom. It is convenient that information is exchanged between the outside and the inside, which makes it necessary to rotate the screen.

However, in order to rotate the conventional multi-vision screen, a rotating mechanism is not attached, and since it is supported only by the casters on the floor during rotation, a specialist contractor is used to prevent falling. Then, the leveler was adjusted, the caster was brought into contact with the floor, the multi-vision was pressed to rotate it to a designated position, and then the height was adjusted by the leveler, and the work of tightening the anchor bolt for preventing fall was performed.

Further, as an example of a rotary base for rotating the screen of a stationary television which is not a multi-vision but is installed in a general home, NEC technique VOL.43 No. 9/1990 page 17,
The “living space proposal design TV” and “4. tilt mechanism” described in 18 can be mentioned.

[0005]

As described above, in order to rotate the screen of the conventional apparatus having a large screen such as multi-vision, only the casters support the multi-vision main body during rotation. Since there is a danger of tipping over if the operation method is moved horizontally and the operation method is incorrect, a specialist must perform rotation work by several people, and the user can freely display the screen in the direction of timely broadcasting. There was a drawback that could not be rotated.

In addition, in the example of the "living space proposal type design television", since the motor is used as a power source for rotating the screen, the number of lead wires is increased, and a connecting mechanism such as a gear mechanism is added. Therefore, there is a problem that the device is expensive but expensive.

Therefore, an object of the present invention is to provide a screen turntable of a television having a large screen such as multi-vision which allows a user to safely and safely rotate the screen in a timely and inexpensive manner.

[0008]

In order to achieve the above object, the lower surface of the multi-vision main body is supported by casters,
And, a rotation shaft whose center is centered with the rotation center position of the lower surface is fixed to the lower surface, and a rotary bearing which is rotatably engaged with the rotation shaft is provided on a base or a floor separated from the lower surface of the multi-vision, The rotary shaft is provided with a vertical stopper for the rotary base.

[0009]

Since the gravity of the multi-vision is supported by the casters, it can be moved horizontally in a plane, and the center of rotation is positioned on the base or floor by the rotating shaft and the rotating bearings. It is dynamically supported and can be easily rotated by pushing the outside of the multi-vision body around the center of rotation.

Further, since the rotating shaft moves only in the rotating direction with respect to the rotating shaft, and the movement is stopped in the vertical direction by the retainer provided on the rotating shaft, the multi-vision main body is relative to the base or the floor. Since it is engaged through the rotary shaft and the rotary bearing, it does not fall.
