Abstract

PROBLEM TO BE SOLVED: To provide a display turntable device for turning a display with minimum force. SOLUTION: The display attached to a fixed base 1 is turned and the fixed base 1 is turned so that a switch 51 or 52 attached to the turntable 2 is pushed/ tuned on by a switch opening/closing projection 1b, to rotate a motor 7 and turn the turntable 2. Further, the legs 1a and 2a of the fixed base 1 and the turntable 2 are slid/rotated on rollers 2c and 3c, to reduce friction caused by the weight of the display, at the time of turning. Then, the turntable 2 starts to turn and the display is turned to a desired set position. After that, a spring 41 or 42 attached from the fixed base 1 to the turntable 2 feeds back the fixed base 1 to between the switches 51 and 52, by a release from a hand at the set position and the switch opening/closing projection 1b is separated from the switch 51 or 52, to stop the turning.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display turntable device, and more particularly to a display turntable device for smoothly rotating a heavy display.

[0002]

2. Description of the Related Art Conventional display turntable devices include a turntable for tilt rotation and a turntable for swivel rotation. When the display is rotated, the turntable is held by one hand and the other hand is held. The display is rotated by, or the display is rotated in a desired direction while holding the display with both hands, and the box 111 of the fixed base 101 in FIG. 3A is the rotary base 1 in FIG. 3B.
02 is engaged with the gear 121, and the tilt rotation switch is turned on after the power is turned on to start rotation. FIG. 3C shows a box 106 attached to the back side of the turntable 102. The box 106 is attached to the turntable 102. 3D, the gear accommodated in the stand 103 of FIG. 3D and housed in the box 106 attached to the rotary base 102 fits with the gear portion 131 of the stand 103, and after the power is input, the swivel rotation switch Start rotation after confirming that it is ON.

Further, the conventional display turntable device is
Since the remote control is performed by remote control, it is rarely used as a turntable of a display, and is often used as a turntable of a television, a home video camera, or the like, which is a function associated with the screen operation of the display. .

[0004]

However, in the conventional display turntable device, the smooth rotation ability of the turntable and the cost of the electric turntable are problems, and the operator has to hold the display by hand. Since the trouble of rotating it as it is, and the heavier the turntable, the smoother the rotation, the electric rotation method by remote control is used, and only the display installed in front is rotated. Not for the purpose of
There is a big problem in terms of cost because the remote controller is provided with a complex function for the purpose of operating the mode in the CRT screen.

Further, by using the remote controller, a light emitting element (infrared light emitting diode) is provided inside the remote controller,
There has been an increase in cost due to mounting a circuit board or the like for controlling this, and a cost increase due to mounting a light receiving element (photodiode) inside the display main body and mounting a circuit board for controlling this.

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-cost display turntable device that minimizes the force for rotating the display mounted on the turntable.

[0007]

In order to solve the above-mentioned problems, a display turntable device of the present invention comprises a fixed base to which a display is attached, a rotary base for electrically rotating the fixed base, and the rotary base. A box having a stand that supports it, a gear that rotates in conjunction with the rotary base, and a motor that drives the rotary base via the gear, and the supply / stop of power to the motor by rotation of the fixed base. And a spring for controlling the rotation of the motor by stopping the rotation of the fixed base and the rotary base by correcting the displacement between the fixed base and the rotary base.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a display turntable device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a top view (A) and a sectional view (B) of a display turntable device according to an embodiment of the present invention.

FIG. 2 is a circuit diagram of a display turntable device according to an embodiment of the present invention.

As shown in FIG. 1, a display turntable apparatus according to an embodiment of the present invention includes a fixed base 1 on which a display is mounted, a rotary base 2 for electrically rotating the fixed base 1, and a rotary base 2 thereof. Stand 3 for supporting and rotating base 2
Gears 61 to 64 that rotate in conjunction with
A box 6 having a motor 7 for driving the rotary table 2 via the switches, switches 51 and 52 for supplying / stopping power supply to the motor 7 by rotation of the fixed table 1, and the fixed table 1.
And the switch 51, 52 by correcting the deviation of the rotation of the turntable 2.
Is opened and the springs 41 and 42 are controlled to stop the rotation of the motor 7.

Also, the rotational force of the switch groove 2f and the fixed base 1 can be freely set in the mounting portion of the switch 51, 52 of the rotary base 2 so that the play distance before the switches 51, 52 are pressed can be freely set. The hook grooves 2e are formed in the turntable 2 so as to be able to set.

Next, the operation of the display turntable apparatus according to the embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the operation of the display turntable apparatus according to the embodiment of the present invention rotates the display mounted on the fixed base 1 to rotate the fixed base 1 and rotate the rotary base 2. Attached to switch 5
When the switch 1 or the switch 52 is pushed into the switch opening / closing protrusion 1b protruding from the fixed base 1, the motor 7 rotates and the rotary base 2 rotates, so that the fixed base 1 and the rotary base 2 rotate smoothly. In order to perform this, as shown in FIG. 1 (B), the recesses 2b inside the turntable 2 and the stand 3,
Rollers 2c and 3c are housed in 3b.

The legs 1a, 2 of the fixed base 1 and the rotary base 2 are also provided.
a slides on the rollers 2c and 3c to reduce friction due to the weight of the display when rotating, and
