The present invention relates to a position adjusting device for a wall-mounted flat panel display device, and more particularly, to a position adjusting device for a display device capable of adjusting left and right tilting and height for fully securing a viewing angle of a wall-mounted display device. .

As the current trend toward larger and slimmer display devices, the spread of wall-mounted television receivers, such as liquid crystal displays and plasma display panels, is expanding, but the situation is limited to simple wall hangings. In other words, the display device itself is fixed to the wall with a bolt or the like, or a metal fixing bracket is fixed to the wall, and a display device is installed on the front of the bracket. There is a problem that the fixed screen is not rotated or the height can not be adjusted according to the change of the posture or the position of the viewer, or the upper angle is changed in the way of fastening the bolt, so that adjustment is not easy.

In addition, the arm type used in the liquid crystal display device can be adjusted vertically, left and right manually, but there is a wide range of position adjustment and free advantage, but the more joints, the higher the production cost and the light weight of the display device itself is 21 inches or less. There is a problem that can be used in a large display device can be applied to the product.

Since the manual holder is completely manual, the installation position is fixed at first, the viewing position of the display device having a narrow viewing angle is limited, and despite the thinning of the display device, the fixing bracket is clunked, and the angle or height change after installation is very limited. There is another problem.

The present invention is to solve the above problems, the object of the present invention is to easily adjust the height, left and right tilt or upper and lower tilt even after fixing the wall-mounted display device on the wall can ensure a variety of viewing angles, automatic The present invention provides a position adjusting device for a display device capable of making fine adjustments to meet the demand for slimmer, larger and more advanced display devices.

First, each component will be described separately as follows.

1 is a view for explaining a wall fixing plate according to the present invention, the fixing rail 100 is installed on both sides of the wall fixing plate 10 of the rectangular plate shape, the fixing rail 100 up and down A sliding moving rail 102 is inserted, and a lead nut fixing bracket 104 to which a lead nut is fixed is attached to the wall fixing plate 10 inside the fixing rail 100, and the fixing plate 10 is attached thereto. The holes 106 are formed to be fixed to the wall by fixing means such as bolts.

2 is a view for explaining a moving plate according to the present invention, it will be described in association with each other.

First, a plurality of motors, a support base and a bracket for supporting a shaft are installed on the plate-shaped moving plate 12 in which both sides are bent in a step shape, and the position thereof may be changed according to the arrangement position of each component.

Here, four tilt gearbox supports 120 are attached to the central portion of the movable plate 12, and tilt shaft supports 122 are installed at both sides thereof, and the gearbox fixing brackets 124 for height adjustment are provided at both lower sides thereof. Is attached. In this case, the moving plate 12 is fixed to the stepped edges on both sides of the moving rail 102, and all the parts of the positioning device are mounted and moved.

3 is a view for explaining the height adjustment unit according to the present invention, the height adjustment unit 14 is fixed to the lower portion of the movable plate 12, the bidirectional height adjustment in which the drive shaft 142 is drawn to both sides The height adjustment is connected to the motor 140, both drive shafts 142 of the height adjustment motor 140 is fixed to the gearbox fixing bracket 124 for height adjustment of the moving plate 12 and converts the rotational force in the vertical direction Retaining bracket of the wall fixing plate 10 and the lead screw 146 connected to the gearbox 144, the other axis of the height adjustment gearbox 144, and the lead screw 146, One side is fixed to 104, and consists of a lead nut 148 to support the weight of the device. Here, the lead screw 146 is located on the back of the stairs of the moving plate 12 and the other end is fixed to the moving plate 12 so that when the lead screw 146 rotates, the lead nut 148 is the lead screw 146 It moves up and down according to the rotational direction of) to move the entire moving plate 12 up and down.

Figure 4 is a view for explaining the tilt portion according to the present invention, the tilt portion 16 is fixed to the quadrant of the upper center of the movable plate 12, respectively fixed by fixing members such as bolts, drive shaft ( Tilt motors 160, 161, 162 and 163, from which the 164 is drawn out, are connected to the drive shaft 164 of the motors and one axis thereof, and the other shaft is connected to the male screw of the screwset 166 and moved. Tilt gearboxes 165 fixed to the gearbox support 120 of the plate 12 and a double column shape, the male screw and the female screw is coupled to the different shafts, but the uniaxial male screw is the upper tilt gearbox A female screw connected to the 165 and the other shaft is connected to the tilt shaft 168 integrally with the screwsets 165 to rotate, and a tilt shaft to which the female screw of the screwset 165 is connected to one side. 168 and the tilt shaft 168 One side is integrally connected, and the other side is composed of a link 169 having a joint portion connected to the display device fixing plate.

Accordingly, when the tilt motors 160, 161, 162, and 163 rotate and the screwset 165 becomes longer or shorter, the tilt shaft 168 rotates so that the end of the link 169 moves up and down. You can tilt left and right or up and down. That is, when two tilt motors 160, 161 and 162 and 163 of the upper side or the lower side operate simultaneously, the tilt of the upper side or the lower side of the display device can be adjusted, and the two tilt motors 160 and 163 are divided to the left and right. ) And 161 and 162 operate simultaneously, it is possible to adjust the left or right tilt of the display device.

The gearbox may be a worm-worm gear, a recreation gear or a barbell gear.

5 is a perspective view of a display device fixing plate according to the present invention, wherein the display device fixing plate 18 having a plate shape having a predetermined shape includes a ball joint part 180 coupled thereto at a portion corresponding to the links of the tilt part. One side of the ball joint is integrally attached to the fixing plate 18, and the other side of the ball joint is coupled to four links 169. The display device fixing plate 18 is supported by four points by the ball joint unit 180.

When the display device is mounted and fixed to the front of the display device fixing plate 18, the height, the left and right tilts and the upper tilts of the display device change according to the movement of the moving plate 12.

Figure 6 is an exploded perspective view of the position adjusting device according to the present invention, Figure 7 is a front view of each device assembled state, in the case of Figure 7, the display device fixing plate 18 is omitted to show the internal assembly situation have.
