Description

Flat TV Vertical Rotating Mechanism

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat panel vertical rotation mechanism, and more particularly, to a flat panel vertical rotation apparatus capable of rotating a wall-mounted flat panel television in a vertical direction.

Recently, the demand for wall-mounted TVs such as plasma display panel TVs, liquid crystal display TVs, etc., is increasing as one of the large display devices. As such, the wall-mounted TVs have the advantages of thinner and lighter weight than conventional CRTs.

These flat TVs are often used on a shelf or wall-mounted. When used as a wall-mounted type, the wall bracket and fixed bracket are included.

That is, the wall-mounting device of the conventional wall-mounted TV is fixed to the wall side bracket for mounting the wall-mounted TV on the wall on which the wall-mounted TV is mounted, and the fixing brackets are screwed to the left and right sides of the back cover of the wall-mounted TV by screws. Each is fastened. Here, the fixing bracket is coupled to the wall side bracket. However, since the conventional wall-mounted device having the above-described structure is only fixed to the wall, it is impossible to freely adjust the direction of the wall-mounted TV in a direction desired by the viewer.

Therefore, there is a problem that can not make the most of the advantages of the wall-mounted TV, such as thin and thin weight, such as the PDP TV or LCD TV.

In addition, the wall-mounted TV is often completely fixed to the wall in a built-in form, which is natural when watching the TV to rotate the screen to match the direction in which the face rotates when lying on a bed or sofa after fixing. There was a problem that it is impossible to fix the bracket.

The present invention is to solve the above problems, it is an object of the present invention to provide a wall-mounted rotating mechanism that can be rotated in the vertical direction at the desired angle of the viewer.

Still another object of the present invention is to provide a wall-mounted rotating mechanism capable of rotating in a vertical direction having a structure in which a flat panel TV can be wall-mounted, but can easily rotate by distributing load.

The above object of the present invention is a flat TV vertical rotation mechanism coupled to the back bracket attached to the rear surface of the flat TV is fixed to the wall in the vertical direction while fixing the flat TV on the wall, the rotating disk coupled to the rear bracket bracket and rotates A rotating drive unit for rotating the rotating disc, a bearing coupled to the rotating disc, and a connecting member dispersing a load applied to the rotating disc while reducing friction when rotating, and a plate shape fixedly installed on a wall and coupled with the connecting member It can be achieved by a flat panel TV vertical rotating mechanism characterized in that it comprises a wall mounting plate and a remote control light receiving unit for outputting a control signal for driving the rotary drive unit after receiving the infrared signal input from the outside.

The flat TV vertical rotation mechanism according to the present invention allows the viewer to easily rotate at a desired angle while minimizing frictional force due to rotation through a bearing coupling to distribute the load of the flat TV evenly to the circular rotating part.

In the flat TV vertical rotation mechanism according to the present invention, most of the load of the flat panel TV is concentrated at the portion where the rotating disc and the connecting member are bearing-coupled. The bearing coupling portion is widely formed in a circular shape coupled between the bearing coupling portion of the rotating disc and the bearing along the "c" groove formed in the connecting member. As a result, most of the load of the flat panel TV is distributed evenly over a large area of the bearing coupling part, and the load of the flat panel TV is hardly applied to the coupling between the driven gear and the rotating disk connected to the drive motor. The effect is to be able to rotate the TV.

Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

1 is an explanatory diagram illustrating a rotation direction of a flat panel TV according to the present invention. As shown in FIG. 1 (a), when the viewer maintains the horizontal direction as in the conventional wall-mounted TV 100, and the viewer is lying on the sofa or the bed, the head of the viewer is turned, so that the angle of the return is shown in FIG. 1 (b). As shown in the figure, the screen of the flat-panel TV was rotated in the vertical direction to be viewed. In the present invention, the remote control light receiving unit 90 is connected to the wire 91 to allow the viewer to remotely adjust the rotation angle using the remote control light emitting unit (not shown). Of course, the wire 91 can be removed and installed wirelessly.

Figure 2 is a cutaway side view of the flat TV vertical rotation mechanism according to the present invention. The flat panel TV 100 is usually provided with a back bracket 110 on the back. The structure of the bracket 110 may be variously modified, which is not a feature of the present invention, and thus detailed description thereof will be omitted. The flat TV vertical rotation mechanism according to the present invention is coupled to the rear mounting bracket 110 to rotate the rotating disc 10, the rotary drive unit 30 for rotating the rotating disc, the rotating rotating disc 10 and the upper bearing The coupling member 40 and the lower bearing 36 are coupled to each other to disperse the load of the rotating disc 10 while reducing the frictional force during rotation, and to be firmly installed on the wall surface 200. It is characterized in that it comprises a wall mounting plate 70 and the remote control receiver 90 is coupled.

The rotating disc 10 is bent in the vertical direction opposite to the flat TV at a position separated by the same distance with respect to the center of the circular top plate portion and the center plate of the upper flat bracket 110 is coupled to the back bracket bracket 110 of the flat TV 100 It is provided with a bearing engaging portion that is formed to extend in the outer horizontal direction. An upper bearing 35 and a lower bearing 36 are inserted into upper and lower bearing coupling portions, respectively.

The connecting member 40 supports the bearing coupling part extending in the outer horizontal direction of the rotating disc 10 from the lower side with the lower bearing 36 interposed therebetween, and the upper side with the upper bearing 35 interposed therebetween. The inner groove is provided at the inner side and the lower end is provided with a connecting member horizontal coupling part which extends outward with respect to the central axis of the rotation disc 10 and engages with the wall attachment plate 70. The wall attachment plate 70 has a plate shape having a predetermined thickness and functions to firmly fix the connection member 40 while being coupled with the wall surface 200.

Figure 3 is a perspective view of the rotary drive unit 30 of one embodiment according to the present invention, Figure 4 (a) is a plan view of a flat TV vertical rotation mechanism of one embodiment according to the present invention, Figure 4 (b) is in the present invention Fig. 1 is a vertical sectional view of the flat TV vertical rotating mechanism according to the embodiment. An example of the implementation of the rotation driver 30 will be described with reference to FIGS. 3 and 4. In FIG. 4B, for convenience of description, a part of the driving motor 14, the driving shaft 19, and the pulley 15 are not shown.

The rotary drive unit 30 includes a bracket 18 screwed to the wall mounting plate 70, and the bracket 15 has a poly 15 formed on the drive shaft 19 of the drive motor 14 fixed to one side thereof. And the pulley 15 'of the primary gear 21 with the rubber belt 22, and the pulley 15', the idle gear 16 and the driven gear 17 on the bracket 18 on the respective shaft 20 , 20 ', 20' '), but the primary gear 21 is engaged with the idle gear 16 and the upper gear 23 of the gear 16 is engaged with the driven gear 17, and driven The rotary disk 10 is coupled to the screw groove 12 formed on the gear 17. Although the bracket 18 of the rotation drive unit 30 has been described as being screwed to the wall mounting plate 70, it may be allowed to be bound by welding, and the repair and the like need to be replaced if the drive motor 14 fails. In order to be able to combine using a separate fastening mechanism such as a hook, of course. Since the rotary disc 10 rotates along the driven gear 17, the central axis of the rotary disc 10 and the central axis of the driven gear 17 must be exactly coincident with each other.

The rotation drive unit 30 presented in the present invention is just one example and can be easily implemented in various equivalent modifications. For example, in the embodiment of FIG. 3, poly and rubber belts are used, but gears and timing belts may be used. Furthermore, in the embodiment of FIG. 3, the rotational force of the motor is transmitted to the driven gear by using a pulley and a gear, but the driven gear is directly connected to the rotating shaft of the motor by using a gear or driven by using a timing belt. Of course, it can be rotated. As the motor used for the rotation drive unit 30 of the present invention, it is preferable to use a step motor capable of adjusting the exact rotation angle.

As shown in Figure 4 (a) and 4 (b) the rotary disk 10 is coupled using a driven gear 10 and a screw screw 11 based on the central axis of rotation of the rotary disk 10, the rotation The disc 10 is bearing-coupled with the connecting member 40, the connecting member 40 is screwed with the wall mounting plate 70 using a screw screw 41, also in the case of the wall mounting plate 70 It is screwed to the wall surface 200 using the screw screw 71. Bracket 18 of the rotation drive unit 30 has been described as being screwed with the wall mounting plate 70, of course, can be joined using a method such as welding, of course.

Figure 5 is a plan view and partly cutaway view of one embodiment applicable to the present invention. 5 (a) and (b) show the structure of the lower bearing 36, the upper bearing 35 is also formed in the same structure. The lower bearing 36 has a bearing 36-1 inserted into a space between the left side wall 36-3 and the right side wall 36-4 formed on a circular base substrate 36-2 having a constant width. It has a structure.

It will be briefly described how to install a flat TV vertical rotation mechanism according to the present invention. First, the wall mounting plate 70 to which the rotation driving unit 30 is coupled is placed on a floor or the like which forms a substantially horizontal surface. Next, the rotation disc 10 is fastened to the screw groove 12 formed on the longitudinal gear 17 by using a screw using a screw screw 11. The lower bearing 36 is positioned on the lower portion of the groove formed in the coupling member 40, and the upper bearing 35 is positioned on the upper portion of the bearing coupling portion of the rotating disc 10. After inserting the bearing coupling portion of the rotary disk 10 into the inner "c" groove of the coupling member 40 is screwed to the wall mounting plate 70 using a screw screw 41. Of course, in the case of the connecting member 40 and the wall mounting plate 70, of course, other fastening methods such as using a latch and hook structure can be used. Then, the wall mounting plate 70 is fixed to the wall using a screw screw 71, and then combined with the rotation plate 10 and the back bracket bracket 110 of the flat panel TV 100 is completed installation.

When the flat TV is installed in the flat TV vertical rotating mechanism according to the present invention, most of the load of the flat TV is concentrated on the portion where the rotating disc 10 and the connecting member 40 are bearing-coupled. The bearing coupling portion is widely formed in a circular shape coupled with a bearing between the bearing coupling portion of the rotating disc 10 and the “c” shaped groove portion formed in the connection member 40. Therefore, most of the load of the flat panel TV is distributed evenly over a large area of the bearing coupling portion, and the coupling between the driven gear 17 and the rotating disc 10 connected to the drive motor 14 causes a load of the flat panel TV. It is rarely applied, allowing the flat panel to rotate with relatively little force.

As shown in FIG. 4 (a), the connecting member 40 is separated into two pieces, thereby easily inserting the bearing coupling portion of the rotating disc 10 into the "c" groove formed in the connecting member 40. I could do it. Reference number 45 shown in FIG. 4 (a) shows a separation line shown on the outer surface when the connecting member 40 is divided into two pieces.

The viewer generates an infrared signal by operating a remote controller to adjust the screen angle of the flat panel TV 100. The remote control receiver 90 receives the infrared signal, amplifies it, analyzes the received control signal using a microcomputer, and then outputs a motor driving control signal. The drive motor 14 finally rotates the rotating disc 10 by rotating the motor shaft and the gear according to the corresponding motor drive control signal to adjust the vertical angle of the screen.
