It is bent and made in contact with one end of the torsion spring (70).

The stand apparatus according to the present embodiment includes an upper and lower angle viewing means for preventing the phenomenon that the viewing angle of the flat-panel television T is changed up and down during the lift operation.

The upper and lower viewing angle maintaining means, the upper rotating cap 80 is fitted to the top shaft 12 is fixed to the upper support 20 through the base frame 10 and rotates together with the top shaft 12, Lower rotation cap 82 and the upper and lower rotation caps 80 and 82 which are fitted to the middle shaft 22 connecting the upper support 20 and the lower support 30 to rotate together with the middle shaft 22. The upper and lower ends thereof comprise a pair of link rods 84 rotatably connected to each other.

According to the stand apparatus according to the present exemplary embodiment configured as described above, the virtual horizontal line formed by the swivel shaft 42 is the Y axis, and the virtual horizontal line perpendicular to the X axis is parallel to the wall surface. When Z is referred to as the Z axis, the television T supported by the swivel bracket 50 moves forward and backward along the Z axis, the up and down slide operation moves along the Y axis, the left and right swivel operation rotated around the Y axis, Up and down tilting operation, which is rotated around the X axis, is possible. Each operation will be described as follows.

First, the front and rear lift operation is performed by pulling the TV T forward or pushing backward (to the wall side) as shown in FIG. 4A. When the front pulley is pulled forward, the upper zone 20 is rotated upward and the front tip is slightly upward. As it rises, the lower support 30 is drawn up by the upper support 20, the angle between the upper and lower support 20, 20 becomes narrow, and the television moves forward to protrude from the wall.

In the case of pushing back, as shown in FIG. 4B, the upper support 20 is rotated downward, and the front end is slightly lowered, so that the angle between the upper and lower supporters 20, 30 is extended, so that the TV is moved backward and the wall surface. It comes close to

When the front and rear lift operation, the structure of the upper support 20 and the base frame 10 (the rear end of the upper support is hinged to the base frame and can be rotated, but the position cannot be moved). At the same time it rises up and moves backwards and at the same time down.

That is, the front and rear lift operation and the up and down slide operation are made at the same time, when the TV moves backward, the rear end of the lower support 30 is lowered, and the connector 64 connected to the bottom shaft 32 is the spring spring. By pulling down the withdrawal end 601 of 60, the spring spring 60 is released to accumulate elastic repulsive force.

Then, the load of the television is canceled by the elastic repulsive force of the spring spring 60 so that the television does not move up and down to maintain its position.

On the other hand, since the front and rear lift operation of the television is made in such a way that the upper support 20 is rotated upward or downward, as a result, the television is the same as the circular motion caused by the rotation of the upper support 20, and the vertical slide operation Is inevitably accompanied by such structural properties.

In this way, according to the operation structure in which the television is rotated by the upper support 20, in the case of the forward movement of the television, the viewing angle of the television is changed upward because the upper support 20 is rotated upward. In this case, since the viewing angle of the television is changed downward because the upper support 20 is rotated downward, it can be seen that an operation factor that unnecessarily changes the viewing angle in the vertical direction during the front and rear lift operation of the television.

However, according to the present embodiment, even when the television is lifted up and down by the vertical viewing angle holding means, the vertical viewing angle of the television is unnecessarily changed regardless of the user's intention. same.

First, when the television is moved forward, the upper support 20 rotates upwards, and as the upper support 20 rotates, the top shaft 12 and the fixed upper rotating cap 80 are relatively upper support 20 It is in the same state as rotating in reverse to).

When the upper rotary cap 80 rotates, both link rods 84 connected to one end thereof cross-move to each other, and the lower rotary cap 82 connected to opposite ends of both link rods 84 also has both link rods 84. ) Rotates in the same direction as the upper rotary cap 80 (relative to the upper support).

Accordingly, the lower rotating cap 82 and the fixed middle shaft 22 also rotate relatively, so that the tilt bracket 40 supported by the middle shaft 22 rotates downward, thereby resulting in a television. Tilt downward to maintain the original viewing angle.

Similarly, when the upper support 20 is rotated downward by moving the television T backward, the television T is tilted upward, so that the vertical viewing angle does not unnecessarily change even during the forward and backward lift operation of the television.

The left and right swivel operation is performed by rotating the television (T) from side to side. According to this, the swivel bracket (50) is rotated from side to side with the swivel shaft supported by the tilt bracket (40) as the axis of view of the television left and right Is adjusted.

At the time of the left and right swivel operation, an appropriate friction force is applied to the swivel bracket 50 by the spring washer unit 44, thereby preventing radical rotation of the television.

In addition, the swivel bracket 50 and the tilt bracket 40 supporting the television T interfere with each other due to the structural characteristics of the tilt bracket 40 having a curved panel form, such that the left and right swivel operations are limited. It does not occur.

Up and down tilt operation is performed by tilting down or tilting up the television (T), whereby the tilt bracket 40 is rotated upward or downward with the middle shaft 22 as an axis and with the tilt bracket 40. The swivel bracket 50 is also rotated, and the viewing angle of the television T is adjusted up and down.

Here, the tilt bracket 40 is always in a state in which a force is downwardly applied by the load of the television T, but the load action of the television T is canceled by the reaction (torsional stress) of the torsion spring 70. As a result, when there is no external force, the television T is kept upright without being rotated up and down, so that the viewing angle in the vertical direction is stably fixed in the state desired by the user.

Therefore, according to this embodiment, the position and viewing angle of the flat-panel television T can be changed in various ways so that the user can watch the television T at a comfortable position.

The above description is only an illustration of the present invention and does not limit the scope of the present invention. That is, the greatest feature of the present invention is to combine the base frame 10 and both supports 12, the swivel bracket 50 and the tilt bracket 40, any modification of the present invention as long as this is satisfied It should be within the scope of the right, which will be more clearly understood by those skilled in the art through the following claims.

As described above, according to the wall-mounted stand apparatus for flat-panel televisions according to the present invention, the use of flat-panel televisions is possible because the three-dimensional operation of moving the flat-panel television back and forth and adjusting the viewing angle vertically and horizontally is possible. This has the advantage of helping to improve convenience.
