Description

[0001] The present invention relates to a position control apparatus for a television receiver,

The present invention relates to a display position adjusting apparatus having an elastic restoring balancing means, and more particularly, to a display position adjusting apparatus having an elastic restoring balancing means for smoothly adjusting an angle when adjusting an angle of a display by an angle adjusting means .

While watching TV is one of the main entertainment and information sources for people, watching TV for a long time at a fixed location makes the body uncomfortable, causing diseases such as periarticular inflammation of the scapula, back pain, spinal cord, and sciatica .

To solve these problems, we tried to make people enjoy TV programs rich and colorful.

Accordingly, in recent years, people can comfortably watch the TV by remotely or manually adjusting the height and time of the TV set according to the viewing angle at their own position, lying or sitting, in order to place the TV set in the optimum time, There is a need for a display position controller that meets the requirements for treating patients with the same disease and hospital bed.

The present inventor has patented a "TV receiver position control device" which is disclosed in Korean Patent Registration No. 10-0521359 and satisfies the above requirements as shown in Figs. 1 to 4.

This allows the viewer to move the TV set to a desired height so as to match the viewer's eye level according to the viewing posture and to view the TV set at a proper angle by adjusting the angle. The frame 1 is provided with a frame A moving block 20 which is supported movably in the up and down direction along the frame 10 and on which the TV receiver 200 is fixed and a moving block 20 for moving the moving block 20 up and down relative to the frame 10 And an angle adjusting means for adjusting the angle of the TV receiver 200 with respect to the moving block 20. [

The elevating means includes a screw shaft 11 which is vertically and rotatably supported on the frame 10 and to which the moving block 20 is screwed, A guide rod 12 and 13 supported by the movable block 20 and slidably coupled to the movable block 20 and a driving motor for driving the screw shaft 11 to rotate.

The angle adjusting means is rotatably connected to the lower portion of the rear side of the TV receiver 200 and the lower portion of the moving block 20 corresponding to the rear side by the engagement of the hinge pieces 201 and 21, A rotary center body 30 rotatably driven by a rotary motor 500 at an upper portion of the block 20 and provided with a vertical protrusion 31 at an end thereof, A link member 32 and a lever member 33 having one end rotatably connected to the other end of the link member 32 and the other end fixed to the upper side of the TV receiver 200.

Such an angle adjusting means is a means for adjusting the angle of the hinge pieces 201 and 21 by the joint action of the rotary center body 30, the link member 32 and the lever members 33, So that it can be rotated around the center. Likewise, the 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 a desired height according to the eye level of a viewer of the TV receiver 200 by driving the screw driving motor and the rotary motor 500 forward and backward, Thereby enabling control by control.

However, when the load of the TV receiver 200 is transferred to the lifting means as it is, the lifting means is lifted down by the gap of the screw 11 when the lifting means is lowered. When the lifting means is lifted, .

In addition, there is a problem that when the load of the TV receiver 200 is transferred to the angle adjusting means to lower the angle, vibration occurs.

The guide protrusion 91 is formed to be long in the vertical direction of the elevating means 30.

The guide groove 92 is formed in the auxiliary bracket so that the guide protrusion 91 is inserted and slid.

When the auxiliary bracket 40 is lifted and lowered by the lifting means 30 in the vertical direction, the guide means 90 slides along the guide protrusion 91 inserted in the guide groove 92 Thereby preventing the auxiliary bracket 40 from flowing.

By mounting the guide means 90 in this way, it is minimized that the auxiliary bracket 40 is prevented from flowing during the lifting movement by the lifting means 30. [

" 형상으로 상호 대응되게 형성된다.The guide projections 91 and the guide grooves 92 of the guide means 90 are formed on the cross-

Quot; shape.

" 형상으로 상호 대응되게 형성됨으로써, 상기 보조브라켓트(40)의 승강운동시, 전후 좌우로 유동되는 것을 잡아주게 된다.As described above, the guide protrusion 91 and the guide groove 92 are formed in the cross-

So that the auxiliary bracket 40 can be moved forward, backward, leftward and rightward when the auxiliary bracket 40 is lifted and lowered.

In the present embodiment, the pressing means 70 and the balancing means 80 are both constituted. Alternatively, only the balancing means 80 can be constructed without the pressing means 70, and the pressing means 70 And the balancing means 80 may be constituted by a well-known structure.

5, a slide hole 16 is formed in the housing 15 so that the main link 50 protrudes and slides in a vertical direction to enclose the components, .

The slide hole 16 is formed in the vertical direction so that the elevation means 30 can perform seesaw motion and elevation movement of the front end of the main link 50 when the elevation means 30 performs seesaw motion and elevation / do.

In the housing 15, speakers may be formed on both sides as required.

By configuring the housing 15 as described above, it is possible to prevent foreign matter such as dust from accumulating on the components installed inside the housing 15. [

The display (T) position adjusting device of the present invention is not limited to the above-described embodiments, and can be variously modified and embodied within the scope of the technical idea of the present invention.
