Then, one end of the locking step 173d is formed in the hook insertion hole 173b.

The set fixing bracket 180 is mounted on the left and right sides of the display, respectively, and an insertion protrusion 181 is formed at an upper portion thereof, and an annular hook 183 is formed at the lower portion thereof.

Looking at the assembly process of the present invention made of the above configuration as follows.

First, the wall fixing bracket 110 to be fixed to the wall.

The first link unit 120 and the second link unit 130 and the second hinge unit 150 hinged to each other by the first hinge unit 140 are configured to interlock with each other on the wall fixing bracket 110.

In addition, the fixing end 161 of the fixing bar 160 is fastened to the third hinge portion 167 formed below the first hinge portion 140 in a rotatable state.

Screw tabs are formed at both ends of the fixing end 161 of the fixing bar 160 to cover the cap 169, thereby preventing separation from the third hinge portion 167.

Then, to couple the second link 130 and the connection bracket 170.

At this time, the fastening hole 171a formed in the mounting hole 131 of the second link 130 and the frame 171 of the connection bracket 170 is fastened through a separate fastening member (not shown).

Next, the set fixing bracket 180 is mounted on the connection bracket 170. In the mounting procedure, the hook 183 of the set fixing bracket 180 is guided to the hook insertion hole 173b of the fixing guide 173 so as to be caught by the locking step 173d provided on the inner side, and then The fixing protrusion 181 of the fixing guide 173 is to be fitted into the projection insertion hole (173a).

At this time, the pin insertion hole (173c) is formed on the side of the projection insertion hole (173a), the insertion hole (181a) is also formed on the side of the fixing projection (181), a separate fastening pin (185) Fasten through). In addition, the left and right ends of the fastening pin is formed with a screw tab to cover the separate cap 186 to prevent the separation.

The assembly process as described above is made at the left right end at the same time.

Referring to the accompanying drawings, the operation state of the ceiling / wall mounting apparatus of the image display device according to the present invention made through the assembly process as described above in detail as follows.

Figure 4 is a side view showing the wall-mounted form of the ceiling / wall mounting apparatus of the image display device according to the present invention, Figure 5 is a side view showing the form of a ceiling hanger of the ceiling / wall mounting apparatus of the image display device according to the present invention.

First, as shown in FIG. 4, the image display device takes a mounting structure in which the image display device is fixed in the form of an initial wall.

In this case, in order to maintain the wall hanging form, the set fixing bracket 180 and the connecting bracket 170 on which the display is mounted are fastened to the second link 130 and rotated together, and the upper end of the connecting bracket 170 The fastening protrusion 175 is inserted into the first link 120 to overlap.

Here, the upper fastening protrusion 175 is formed with a pin hole 175a, the upper fastening hole 123 is formed on the side of the first link 120 to match the upper fastening hole 123 and Through the pin hole 175a to fasten the fastening pins 124 to maintain the engaged state.

The fastening pin 124 has a screw tab formed on both ends and has a structure to cover a separate cap (124a).

At this time, the fixing bar 160 is a state in which the free end 165 is naturally struck downward by its own weight while the fixing end 161 is mounted on the third hinge portion 167.

Then, when you want to change the mounting structure from the wall hanging form as shown in the ceiling hanger form as shown in Figure 5 is subjected to the following process.

First, the fastening state of the upper fastening protrusion 175 of the connection bracket 170 which is fastened to the upper fastening hole 123 of the first link 120 by the fastening pin 124 is released.

The connection bracket 170 in which the fastened state is released is unfolded downward by its own weight. At this time, the connecting bracket 170 is rotated 180 ° with the second hinge portion 150 as a vertex.

When the connection bracket 170 is 180 ° rotated as described above, the lower fastening protrusion 176 overlaps the inside of the first link 120 and is inserted.

Here, the lower fastening protrusion 176 is formed with a pin hole 176a, the lower fastening hole 125 is formed on the side of the first link 120 to match the lower fastening hole 125 and The fastening pins 124 are fastened through the pin holes 176a.

The fastening pin 124 uses the fastening pin 124 that was used to fix the upper fastening protrusion 175 again.

As a result, the first link 120 and the connection bracket 170 can be maintained in a straight state.

Then, the first link 120 and the connecting bracket 170 are rotated upward by 90 ° with the first hinge portion 140 as the apex, so that the free end 165 of the fixing bar 160 is the first. To be inserted into the hook groove 121 of the link 120. In this case, the fixing bar 160 supports the weight of the display D.

This takes the form of a ceiling hanger in which the display D faces the floor.

And, if you want to change the mounting structure in the form of the ceiling hanger in the form of the ceiling hanger as described above, after releasing the fixing bar 160, the second hinge portion 150 to the vertex connecting bracket 170 Follow the process of fastening with the fastening pin 124 to be rotated.

According to the ceiling / wall-mounted device of the image display device of the present invention as described above, it is possible to use two kinds of mounting forms in one set.

The present invention has the effect that can be used at the same time the wall and ceiling hanging form by the mounting structure of the image display device consisting of a combination of a plurality of hinge parts and links.

This makes it possible to satisfy the needs of various consumers.
