DETAILED DESCRIPTION OF THE INVENTION

Exemplary embodiments of the present invention will now be described in detail with reference to the annexed drawings. In the following description, a detailed description of known functions and configurations incorporated herein has been omitted for conciseness.
As shown in FIGS. 1 to 6, an automatic wall mounting system for a wall-mounted television (TV) according to an exemplary embodiment of the present invention includes a fixing plate 10 fixingly mounted on a wall body 5, and having fixing rails 12 and sliders 14 at its both side ends, the sliders 14 sliding on the fixing rails 12; an elevating plate 20 coupled at its both side ends to the sliders 14 of the fixing plate 10, and having a television (TV) 8 in its front; and an elevation manipulation unit 30 coupled to each of the fixing plate 10 and the elevating plate 20, and elevating or descending the elevating plate 20 about the fixing plate 10.
The fixing plate 10 is of a shape in which a rectangular iron plate is fixingly mounted on the wall body 5. The fixing plate 10 has the fixing rails 12 at its both sides. The fixing plate 10 has the sliders 14 slidably coupled to the fixing rails 12 and sliding up/down on the fixing rails 12.
“L”-bracket shaped nut fixing parts 16 for fixing lead nuts 34 are attached onto the fixing plate 10 adjacently to and at inner sides of the fixing rails 12. Coupling holes 18 for coupling predetermined coupling members (not shown) such as bolts are provided at upper and lower parts of the fixing plate 10 adjacently to and at inner sides of the nut fixing parts 16.
The fixing plate 10 is partially cut away at its central part and thus has a through-hole 19 for raw material saving because its central part serves no role.
The elevating plate 20 is of a rectangular plate shape in which it is bent and stepped at a lower end and both ends. A motor 31 of the elevation manipulation unit 30 is installed at a lower-end bent part 20 a, and the sliders 14 of the fixing plate 10 are coupled with both-end bent parts 20 b. In particular, the lower-end bent part 20 a is cut away at its both ends and thus has a screw insertion part 20 c such that a lead screw 33 of the elevation manipulation unit 30 is inserted into the screw insertion part 20 c and is disposed in rear of the elevating plate 20.
The elevating plate 20 has screw supports 22 at each of both-side upper and rear parts. The screw supports 22 cover upper parts of the lead screws 33, and support the lead screws 33 such that the lead screws 33 can axially rotate.
A gear box fixing part 24 is provided at a portion corresponding to an outer side surface of the screw insertion part 20 c of the elevating plate 20. The gear box fixing part 24 fixes a gear box 32 of the elevation manipulation unit 30.
Coupling holes 25 for fixingly mounting the TV 8 through a separate coupling hole (not shown) are provided at four corners of a central flat part of the elevating plate 20.
The elevation manipulation unit 30 includes a motor 31 provided at a central part of the elevating plate 20, and having a cylindrical rod 31 a axially rotating in forward and reverse directions; the gear box 32 provided at an end of the rod 31 a of the motor 31, and converting an axial rotation force of the rod 31 a into a vertical rotation force; a cylindrical lead screw 33 connecting at its one end with the rod 31 a through the gear box 32 and extending at the other end to an upper side of the elevating plate 20, and having a screw thread on its circumferential surface; and a rectangular box shaped lead nut 34 spirally coupled with the lead screw 33 and fixingly coupled to the fixing plate 10, and opened at its axial center and upper surface such that the lead screw 33 spirally moves in an up and down direction as rotating.
The rods 31 a of the motor 31 protrude from both sides of the motor 31, thereby providing a coupling structure among the gear box 32, the lead screw 33, and the lead nut 34 each having the same construction.
It is desirable that the gear box 32 connects the lead screw 33 with the rod 31 a in a worm gear manner. In detail, worm gears connect to ends of the rod 31 a and the lead screw 33 that interconnect with each other. The worm gears are geared with each other, and transmit the rotation force of the rod 31 a to the lead screw 33 disposed in a vertical direction.
In addition to the worm gear, the gear box 32 can apply a combination of various gears such as a rack pinion gear or a bevel gear for converting the rotation force into the vertical rotation force.
The automatic wall mounting system for a wall-mounted television TV according to an exemplary embodiment of the present invention is completely assembled as follows. First, the fixing plate 10 is fixed to the wall body 5. Next, the elevation manipulation unit 30 is installed by disposing the lead screws 33 in rear of the elevating plate 20. After that, the both-end bent parts 20 b of the elevating plate 20 are coupled to the sliders 14 of the fixing plate 10. At the same time, the lead nuts 34 screwed and coupled with the lead screws 33 of the elevation manipulation unit 30 are fixingly coupled to the nut fixing parts 16 of the fixing plate 10. Finally, the TV 8 is fixingly mounted via the front coupling holes 25 of the elevating plate 20.
In this state, a viewer can control the screen height of the TV 8 at his/her eye level in a remote place, using a remote controller.
For example, when it is intended to control the screen height of the TV 8, the motor 31 is driven to rotate the rod 31 a in a desired direction. The rotation force of the rod 31 a causes rotation of the lead screw 33 that is disposed in the vertical direction through the gear box 32. This results in spiral movement of the lead screw 33 about the lead nut 34 that is fixed to the fixing plate 10. Finally, the spiral movement causes the elevating or descending of the elevating plate 20 integrally connecting with the lead screw 33 in a desired direction, thereby controlling the screen height of the TV 8.
As described above, the automatic wall mounting system for a wall-mounted television TV has an effect of automatically controlling the screen height of the TV at the viewer's eye level in the remote place, thereby providing the optimal screen position to the viewer in real time while enabling a prompt, simple, and convenient control of the screen height by automation.
While the invention has been shown and described with reference to a certain preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
