The installation process and operation of the wall-mounted device of the image display device according to the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

5 is a side view showing an operation state of the wall-mounted device of the image display device according to the present invention.

First, the lower end of the inclination adjustment bracket 130 is hinged by a two-point assembly structure, and the pair of wall fixing brackets 110 so that the upper end is coupled by the angle adjustment link 140, the width adjustment bar 120 Combine to maintain a certain interval by.

At this time, the width adjusting bar 120 is to be coupled to each one of the top and bottom of the wall fixing bracket 110 to take a stable structure of the rectangular frame.

After the wall fixing bracket 110 is slid on the width adjusting bar 120 and the width is adjusted according to the size of the image display device set, the wall fixing bracket 110 is separately mounted on the wall surface. It is to be fixed using a fixing member (not shown).

Next, after the set fixing bracket 150 is mounted on the rear surface of the image display device set, the set fixing bracket 150 is coupled to the inclination adjusting bracket 130.

At this time, by forming the mounting hole 151 of the set fixing bracket 150 in the long hole shape, it is possible to change the mounting position of the mounting member (S) according to the standard of the image display device set.

After the image display device set M is mounted on the wall-mounted device by the installation process as described above, the user arbitrarily adjusts the inclination angle of the image display device set M to match the desired viewing angle.

At this time, the tilt adjustment principle provided by the wall-mounted device of the image display device according to the present invention is designed to have a proper friction force in the hinge portion to withstand the weight of the set itself so that the tilt adjustment is made.

The present invention uses the angle adjustment link 140 and the two-point coupling structure as a way to adjust the inclination by the friction force design in the hinge portion.

First, the angle adjusting method using the angle adjusting link 140, the angle adjusting link 140 combines the plate spring 141 and the groove washer 143 in a suitable arrangement to form a friction force Thereafter, the hinge shaft 145 is fastened to a proper torque to form the joint portion H. These joints (H) after adjusting the image display device set (M) to the appropriate inclination, the image display device set (M) does not tilt or change the inclination angle due to its own weight, when the user wants to adjust the arbitrary inclination angle less force It is most important to be tightened with a torque that can be adjusted to a degree.

And, more preferably, the plate spring 141 and the groove which has a frictional force to the first link coupling portion 119 and the second link coupling portion 137 which are hinged to both ends of the angle adjustment link 140, respectively Groove washer 143 may be made of a combination of the hinge shaft 145 to increase the effect.

Next, the tilt control method using the two-point coupling structure, when the tilt of the image display device set (M), the first coupled to the lower first pin fixing hole 132 of the tilt adjustment bracket 130, Hinge pin (P1) is a center of rotation is moved by the (a) to the top through the first pin guide hole 116 of the wall fixing bracket 110.

At this time, the second hinge pin (P2) is coupled to the second pin fixing hole 115 of the wall fixing bracket 110 to move the second pin guide hole 131 formed in the inclination adjustment bracket 130. Guidance will be made.

The two-point coupling structure of the present invention generally has a moment as much as the distance (L) from the one-point coupling structure that forms only one hinge portion to the hinge portion with the center of gravity of the image display device set (M). On the other hand, in the two-point coupling structure according to the present invention, in order to adjust the inclination of the image display device set (M) to lift the weight (1) as much as the structure to be inclined adjustment, the generated frictional force is It acts as a reaction force of the moment to be tilted, thereby reducing the influence caused by its own weight, so that it can be operated more smoothly and safely when adjusting the tilt of the set.

The two-point coupling structure of the wall-mounted device of the image display device according to the present invention as described above is the self-weight of the image display device set M and the first and second hinge pins P1 and P2 and the first and second pin guide holes. The friction force at (116,131) is generated to achieve a smooth operation without using the return spring, thereby performing the inclination adjustment function independently without depending on the friction force of the upper angle adjustment link 140 You can do it.

In addition, even when the upper angle adjustment link 140 is damaged, the first and second hinge pins P1 and P2 may perform a stopper function, thereby ensuring reliability and stability.

Figure 6 is an exploded perspective view showing a packaging state of the wall mounting apparatus according to the present invention, as shown in the figure is a wall mounting apparatus according to the present invention is to be able to disassemble and assemble into a small number of units.

Therefore, when the wall-mounted device of the present invention is separated into a single piece, it can be separated into four single pieces as shown in FIG. 6, and it is possible to pack them in a compact size by stacking them in the longitudinal direction again.

Due to this, not only the transportation and storage is simple, but also the cost can be reduced, and the installation can be made very simple.

The present invention as described above has various effects as follows.

First, the present invention has an effect that can be applied to the image display device of a variety of standards by allowing the set position of the left and right and top and bottom of the wall mounting apparatus can be arbitrarily changed.

Secondly, the present invention has an advantage that the angle can be adjusted without using a return spring by using the linkage and the two-point coupling structure for adjusting the angle by the weight and friction of the set.

Third, the present invention performs the stopper function by the first and second hinge pins forming the two-point coupling structure of the lower part even if the upper angle adjustment link is broken, thereby preventing inadvertent accidents, thereby ensuring reliability and stability. It becomes possible.

Fourth, the present invention is easy to disassemble and assemble into a single unit, it is possible to pack in a compact (compact) size is very easy to transport and storage, it has a great effect in reducing the logistics cost, and has the effect of improving productivity.

Fifth, the two-point coupling structure of the present invention is a structure that halves the moment due to the set weight, and has an effect of enabling the angle adjustment of the set with a small force.
