Display position adjusting device using sector gear

The present invention relates to a display position adjusting device using a sector gear, and in particular, even when the display is mounted on one side, the load is not eccentric to one side to smoothly drive the lifting unit, and a lead coated with oil such as grease. The present invention relates to a display position adjusting device using a sector gear that protects the screw from dust and the like to enable smooth rotational driving.

While watching TV is one of the main entertainment and information sources for people, watching TV for a long time in a fixed position causes discomfort and causes diseases such as periarthritis of the scapula, low back pain, spondylosis, and sciatica. You can.

To solve this problem, we tried to make people enjoy the rich and colorful TV programs.

Thus, in recent years, people can comfortably watch TV by remotely or manually adjusting the height and time of the TV set according to the viewing angle at their lying or sitting position in order to position the TV set within the optimal view. There is a need for a display positioning device that satisfies the requirements to be treated by patients with the same disease and hospital beds.

The present inventor is disclosed in Korean Patent Registration No. 10-0521359, and as shown in Figs. 37 to 40, the patent registration "TV receiver position control device" that satisfies the above requirements.

This allows the viewer to move the TV receiver to a desired height according to the viewer's eye height, and to adjust the angle so that the viewer can watch at an appropriate angle. 10), a movable block 20 which is supported to be movable up and down along the frame 10 and to which the TV receiver 200 is fixed, and which lifts the movable block 20 with respect to the frame 10. Lifting means and the angle adjusting means for adjusting the angle of the TV receiver 200 with respect to the movable block 20.

The elevating means is supported by the frame 10 to be rotatably extended in the vertical direction, the screw shaft 11 is screwed to the movable block 20, and the frame shaft parallel to the screw shaft 11 And a

guide rod

12 and 13 to which the movable block 20 is slidably coupled, and a driving motor to rotate and drive the screw shaft 11.

The angle adjusting means, the lower portion of the rear side of the TV receiver 200 and the lower portion of the movable block 20 corresponding thereto are rotatably connected by the coupling of the

hinge pieces

201, 21, the movement Rotatingly driven by the rotary motor 500 in the upper portion of the block 20 and the vertical center portion 31 is formed at the end and the rotary core 30, one end is rotatably coupled to the end of the vertical protrusion (31) The link member 32 and one end is rotatably connected to the other end of the link member 32 and the other end has a structure provided with a lever member 33 fixed to the upper side of the TV receiver 200.

The angle adjusting means is such that the

hinge piece

201, 21 by the joint action of the rotation center 30, the link member 32 and the lever member 33 by the forward and reverse driving of the rotary motor 500. It can be rotated to the center. Similarly, this rotary motor 500 is remotely controlled by a remote controller 310 employing a light receiving sensor and a light emitting sensor. Therefore, the viewer 300 can control the angle of the TV receiver 200 at a desired angle at the viewing position.

Such a device can be moved to the desired height to fit the viewer's eye height of the TV receiver 200 by the forward and reverse driving of the screw drive motor and the rotary motor 500, and also to adjust the angle to watch at a suitable angle remote Control by control.

However, such a device has a structure in which the screw 11 is exposed to the outside and the contamination rate due to foreign matter such as dust in oil such as grease applied to the screw 11 due to static electricity by the TV receiver 200 is high. There is a problem in that the lifting operation is not smooth and the cleaning cycle is shortened.
