The present invention relates to a tilt device that enables a viewer to effectively watch by positioning a screen direction of a TV receiver or a monitor at any desired angle.

In general, since a TV receiver or a monitor is manufactured so that the height of the screen itself cannot be adjusted, the screen is raised or lowered by adjusting the height so that viewers can easily watch using a support die or the like.

However, when the viewer is sitting or lying down, the viewing direction and the TV screen direction are different from each other, so that the area of the viewable screen becomes narrower, which makes the viewing uncomfortable, and the center of gravity of the TV receiver tilts. In order to prevent the TV receiver from falling because it changes with the load, it was necessary to provide a countermeasure corresponding to the load to fall of the TV receiver according to the change of the center of gravity below the TV receiver.

Therefore, in recent years, by installing various driving devices in the support die on which the TV receiver is placed, the TV receiver is tilted or rotated stably so that the viewer can adjust the screen to a desired position so that they can watch the screen effectively. A device for preventing the TV receiver from falling due to the change in the center of gravity has been complicated. These will be described below. As such a conventional apparatus, as described in Japanese Laid-Open Utility Model Publication No. 61-113477, a slider capable of moving left and right is provided on a plurality of screw shafts driven by a motor, and the shaft is centered on the upper end of the slider. By installing a support plate that rotates in a vertical direction, the TV receiver and the like can be tilted up and down.

However, such a device has a problem that not only the structure is complicated but also the cost increases due to the increase in the number of parts.

In addition, the tilting device 100 as shown in FIG. 5 has a reduction gear 3 engaged with the gear 2 of the motor 1 installed in the fixing member 10 and connected with the rack 4. The support member 5 is rotated about the axis 6 of the support member 5 according to the driving of the motor 1, and the support members 5 are respectively installed on both sides of the support 7 in the center. The spring 9 is fitted to the lower guides 8 and 8a to smoothly rotate when the support member 5 is operated.

However, when the motor 1 is driven, the repulsive force F acts on the contrary to the rotational direction of the motor 1 by the constant constant of the springs 9.

That is, a predetermined tensile force is applied to the spring 9 on one side while the support member 5 rotates about the shaft 6, so that the motor 1 has a repulsive force F in the direction of the arrow as shown in FIG. 5. ) Acts, and when the support member 5 is rotated in the opposite direction, the direction of the repulsive force (F) is reversed.

Therefore, when this repulsive force F is large, there exists a problem that it will cause a bad influence on the driving force of the motor 1.

This invention has been made in view of the above-mentioned conventional problems, and an object of this invention is to make it possible to immediately and safely support the movement of the center of gravity due to the tilt of the TV receiver, thereby safely tilting the TV receiver. The present invention also provides a tilting apparatus for a TV receiver that can smoothly drive the support member without vibration.

A feature of the present invention for achieving the object as described above, in configuring the tilt device for adjusting the up and down screen of the TV receiver, while forming support pins on both sides of the center of gravity of the TV receiver, An arc-shaped support member is installed on the bottom surface of the TV receiver, and an arc-shaped support member is drawn around the center of gravity, and the support member is hinged on the upper surface while the support member is hinged to the pedestal on which the TV receiver is to be installed. And a driving gear which is rotated by a motor and engaged with the gear part of the supporting member is formed in the inner side thereof. It can be installed to limit the rotation angle of the support member.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Figures 1a, 1b to 4 are views for explaining the tilt device of the TV receiver according to the present invention, as shown in Figures 1a, 1b protruding the support pins 102 on both sides of the center of gravity of the television receiver 101 And a support 31 to which the support pins 102 are hinged on both sides of the pedestal 30 to be installed below the TV receiver.

And, as shown in Figures 2 to 4, the bottom of the TV receiver is provided with a support member 40 having a bottom surface arc-shaped, the arc surface of the support member 40 is the center of gravity of the TV receiver An arc surface ("R") is formed around the support pin 12, and the supporting member 40 forms a groove 40a at the center thereof, and then forms a gear 41 in the groove 40a. The drive gear 45 to be described later to be meshed with the gear, the bearing 44 is guided on one side of the circular arc surface on both sides and the projections 42 are formed on the other side to limit the inclination angle of the TV receiver.

In addition, the pedestal 30 forms an installation groove 30a in the shape of an arc such that the support member 40 having the arc shape is installed in the shape of an arc, and an arc surface of the support member 40 is formed in the installation groove 30a. At least one bearing 44 in contact with the guide is arranged and the limit switch 43 is provided at the other predetermined position to limit the inclination angle of the TV receiver 102 within a predetermined angle range.

In addition, a motor 46 that can be remotely controlled by a remote controller (not shown) is installed at a predetermined position inside the pedestal 30, and the gear 46 of the support member 40 is installed on the motor 46. A drive gear 45 engaged with 41 is provided to adjust the inclination angle of the support member 40 at a predetermined angle.

This design as described above allows the viewer to view the screen at any desired angle when the screen orientation of the TV receiver 101 does not match the viewer's line of sight as shown in FIGS. 1A, 1B to 4. When the remote control is operated to position the remote controller, the remote control signal is recognized by a microcomputer (not shown) installed in the receiver of the tilt apparatus 20 to drive the motor 46.

As the motor 46 is rotated, the support member 40 having the gear portion 41 engaged with the drive gear 45 by the drive gear 45 engaged therewith is rotated at a predetermined angle with respect to the support pin 102. It is rotated, but at this time, one side arc surface of the support member 40 installed on the bottom of the TV receiver 101 is guided in contact with the bearing 44 installed on the pedestal 30, the support member on which the TV receiver 101 is installed on the top. 40 is inclined at a predetermined angle smoothly and smoothly.

In addition, even if the TV receiver 101 is inclined according to the rotation of the motor 46, the bottom surface of the TV receiver 101 forms an arc surface centering on the center of gravity of the TV receiver 101, that is, the support pin 102. Due to the center of gravity does not change, and the TV receiver is hinged to the support pin 102 on the support 31 of the support 30 to be able to adjust the tilt angle as desired for the TV receiver.

And as shown in FIG. 3, the limit switch 43 is provided in the predetermined position of the installation groove 30a of the base 30, and the maximum inclination angle of a TV receiver is located in the predetermined position of the one side arc surface of the support member 40. As shown in FIG. The projections 42 limiting the angle are formed, so that the angle can be adjusted only within a certain range.

This invention is constructed and operated as described above, while installing a support member having an arcuate surface at the lower end of the TV receiver at the center of the center of gravity of the TV receiver, by installing the hinge of the center of gravity of the TV receiver as a support, the purpose of the TV receiver The angle can be adjusted stably by a predetermined angle, allowing viewers to conveniently view the screen, and the structure of the tilting device of the present invention that safely adjusts the angle of the TV receiver is very exceptionally simple and smooth. It is an effective design.
