As shown in Figures 1 to 4, the stand apparatus 1 for flat-panel TV monitors according to an embodiment of the present invention is a stand base 10 consisting of a bottom plate 11 and the base cover 12, TV In the TV stand device comprising a bracket 30 is fixed, a hinge device for pivotally connecting the bracket 30 to the stand base 10, is coupled to rotate integrally with the bracket 30 Shaft 51, the stator 53 is fixed to the bottom plate, POM bush is coupled between the shaft 51 and the stator 53 to generate a torque when the shaft rotates, the POM bush to the shaft 51 A hinge device 50 including a washer 57 to be fastened and a nut 58 is provided.

Here, the POM bush is composed of an upper POM bush 55 and a lower POM bush 56 to be integrally coupled to the upper and lower portions of the stator 53 and spaced apart from the upper and lower POM bushes 55 and 56. Fitted to the shaft 51, the upper POM bush 55 is provided with a flange (55a) to be rubbed with the bracket 30, the lower POM bush (56) is a flange 56a is rubbed with the washer (57) Is preferably provided.

In addition, the stator 53 is formed with a central through hole 53a formed with at least one key protrusion 53b on an inner circumferential surface of the upper and lower POM bushes 55 and 56 so as to be integrally coupled to the stator 53. An open space 53c which forms a step with the 53a is formed, and on the outer circumferential surface of the upper and lower POM bushes 55 and 56, the keyhole grooves 55b and 56b corresponding to the key protrusion 53b are formed. A plurality of these places are formed.

In order for the shaft 51 to be integrally coupled to the bracket 30, the shaft 51 has a flat cut portion 51a formed on a main surface thereof, and a corresponding cross section for being fitted over the shaft 51 on which the flat cut portion is formed. Key-type through hole (71) corresponding to the shape is formed is preferably provided with a washer bracket (70) to be formed to bend one or more protruding claws 73 is fitted to the bracket (30) on the outer edge. Accordingly, the claw fixing hole 32 into which the claw 73 is fitted is formed in the bracket 30.

In addition, the bracket 30 has a stopper protrusion 35 disposed on the side of the stator 53 at one side thereof, and the stator 53 is restricted so that the stopper protrusion 35 is moved within a predetermined angle range. 53 d of stopper holes may be formed.

In addition, the nut 58 is preferably a nylon nut is employed to increase the torque adjustment function.

The bracket 30 is integrally formed with a standing part 31 on which a TV monitor is mounted and a horizontal part 33 connected to the hinge device 50, so as to distribute load bearing capacity.

It is preferable that a rib 37 is formed in which the part of the standing part 31 and the part of the horizontal part 33 are bent and symmetrically formed in symmetrical direction (see FIG. 6).

In the drawings, reference numeral '13' is a stopper for opening of the bottom plate, '14' is a cable reel, '15' is a buffer support, and '81' is a fastening member for fastening the stator 53 to the bottom plate.

It looks at the working state of the flat-panel TV monitor stand device 1 according to the present invention having such a configuration.

The core of the present invention is the POM bush (55) between the stator and the friction 53 is generated when the shaft (51) rotates integrally with the bracket for adjusting the angle of the bracket 30, the flat panel TV monitor is fixed (56) is given.

The POM bushes 55 and 56 have properties such as lubricity, durability, fatigue resistance, creep resistance, resistance to friction and abrasion, which are inherent to polyoxymethlene (POM), without using a lubricant such as grease. And the reliability is significantly improved compared to the prior art, and enables a significantly compact configuration compared to the prior art using the disk spring.

That is, the body of the POM bushes 55 and 56 at the friction portion between the movable side rotated integrally with the bracket 30 and the fixed side fixed to the stand base 10 when the angle of the TV monitor and the bracket 30 is adjusted. Is friction with the outer circumferential surface of the shaft 51 and the upper and lower flanges 55a and 56a cause friction to the bracket 30 and the washer 57, respectively, since the POM bushes 55 and 56 have the above characteristics. Rotation adjustment can be made smoothly without adding lubricant, and torque generation is stable.

In addition, by adjusting the friction area of the POM bushes 55 and 56 according to the load of the TV monitor, it is possible to apply everything from large TV monitors to small ones.

In addition, by adjusting the frictional pressure of the POM bush against the shaft using the nylon nut 58, torque adjustment is made easier.

In addition, the POM bush 55, 56 on the surface of the stator 53, which is rubbed with the shaft 51 is rubbed with a predetermined pressure at the top and bottom, which is accompanied in the prior art by a simple configuration in which torque is generated when the shaft is rotated. By eliminating a large number of space washers, the number of parts and the assembly process are greatly reduced and manufacturing cost is greatly reduced.

In other words, in the present invention, only one washer 57 is provided in the present invention, whereas four washers including a space washer were involved.

In addition, part of the standing part 31 of the bracket 30 and part of the horizontal part 33 are cut and bent, and are composed of ribs 37 joined by riveting or the like, so that the load of the TV monitor applied in the vertical direction is distributed. As a result, the bearing capacity is increased and the thickness of the bracket material can be reduced, thereby reducing the material cost.

In addition to this, the bracket 30 is provided with a stopper protrusion 35 so as to be able to rotate only in a certain angle range with respect to the stator to have a stopper function.

The present invention is not limited to the above-described embodiments and drawings since various substitutions, modifications, and changes are possible to those skilled in the art without departing from the technical spirit of the present invention. .

As described in detail above, the flat panel type TV monitor stand apparatus according to the present invention is provided with a POM bush as a torque generating member, which requires no lubricant, greatly improves reliability compared to the prior art, and increases the number of parts and the assembly process in the prior art. Compared to the compact structure, which is significantly reduced, the manufacturing cost is greatly reduced.

In addition, since a portion of the bracket is cut and bent, ribs have an effect of increasing bearing capacity and reducing material costs.
