According to the present invention, the main body can be prevented from being separated from the wall by the supporting bracket integrally formed with the main body, and the fitting bracket connecting the fixing bracket fixed to the wall.

Accordingly, the fixing bracket and the fitting bracket are housed in the recess formed in the main body. In order to fix the main body to the wall while being supported on the ground by the frame formed to enclose the main body, A fitting structure of a shape projecting from the main body is unnecessary.

Hereinafter, a structure in which the main body is fixed to the wall by the fixing bracket and the fitting bracket will be described in detail.

FIG. 4A is a conceptual view for explaining a structure in which a fixing bracket and a fitting bracket are mounted on the recess portion, and FIG. 4B is a sectional view taken along the line A-A 'in FIG.

3A, 4A and 4B, one side of the support portion 103 and the fixing bracket 310 are fixed to contact with each other, and the fixing bracket 310 is fixed to the recess portion 104. The rear surface 101b and the other side surface of the fixing bracket 310 are arranged to form one plane.

Both sides of the fitting bracket 320 are fitted into the first opening area 311 of the fixing bracket 310 and the second space 104b. The upper surface of the fitting bracket 320 may be formed in one plane with the upper surface 101b of the main body 101. [

However, a step may be formed by the fitting bracket 320 and the fixing bracket 310. The fixing bracket 310 according to the present embodiment does not form a plane with the upper surface 101b of the main body 101. [ However, the present invention is not limited thereto.

Referring to FIG. 4A, the fixing bracket 310 may be formed to be flush with the fitting bracket 320 and the upper surface 101b of the main body 101. Referring to FIG. In this case, as shown in FIG. 3E, the length of one side of the fixing bracket 310 fixed to the wall w may be longer than the length of the other side.

5 is a conceptual diagram for explaining a fixing method of fixing the main body to the wall using the fixing bracket and the fitting bracket.

5 (a), the fixing bracket 310 is fixed to the wall w by a fastening member 10 formed of a nail or the like. The fastening member 10 is fixed to the wall w through the first hole 310 '.

5 (b) and 5 (c), the main body 101 is moved adjacent to the wall w, and the fixing bracket 310 is disposed in the first space 104a . The fitting bracket 320 is inserted in the first direction d1 in a state where the fixing bracket 310 is supported by the support portion 103. [ The top surface 101b of the main body 101 and the surface of the fitting bracket 320 exposed to the outside are separated from each other by the shape of the fitting bracket 320, This one plane can be achieved.

Accordingly, since the main body is fixed to the wall using the structural features of the fixing bracket and the fitting bracket, no separate bonding structure or deformation of the main body is required.

6A and 6B are conceptual diagrams for explaining a guide portion for guiding the engagement between the fixing bracket and the recessed portion.

Referring to FIG. 6A, the first holes 310 'are formed on both sides of the fixing bracket 310 in order to facilitate the assembling process for penetrating the fastening member 10.

Meanwhile, the supporting portion 103 according to the present embodiment includes a plurality of first guide members 104 formed to correspond to the first holes 310 '. The thickness of the guide member 105 is preferably substantially equal to the thickness of the one side of the fixing bracket 310.

When the fixing bracket 310 is mounted in the first space 104a, the plurality of guide members 105 are fitted into the plurality of first holes 310 '. The first and the second directions d1 and d2 of the support portion 103 and the fixing bracket 310 are formed by the guide member 105 inserted into the first hole 310 ' Relative movement to the three directions (d3) is prevented.

Therefore, the main body 101 can be prevented from moving with respect to the wall when the main body 101 is fixed to the wall by the fixing bracket 310 and the fitting bracket 320, The main body 101 can be more stably fixed to the wall.

Referring to FIG. 6B, a guide unit according to another embodiment will be described. The main body 101 includes guide protrusions 106 protruding substantially in the direction in which the support portions 103 protrude (in a direction opposite to the first direction d1 in Fig. 6B). In addition, the fixing bracket 310 includes the guide groove 312 which is recessed to fit the guide protrusion 106. The guide protrusion 106 and the guide groove 312 may extend along the second direction d2. The protrusion height of the guide protrusion 106 may be smaller than or substantially equal to the thickness of the fixing bracket 301.

The guide protrusion 106 is inserted into the guide groove 312 while the fixing bracket 310 is fixed to the wall so that the main body 101 is brought into close contact with the wall w. Accordingly, the main body 101 can be prevented from being fixed to the wall and from moving after being fixed.

7A to 7C are conceptual diagrams for explaining a reinforcing part for stably fixing the wall and the main body. Since the recess portion 104, the fixing bracket 310, and the fitting bracket 320 are separately formed, they may be formed to have different sizes, and accordingly, a gap may be formed between the respective components have. According to the present embodiment, the gap is filled by the reinforcing portion formed between the components. Hereinafter, a specific structure of the reinforcing portion according to various embodiments will be described.

Referring to FIGS. 3A and 7A, the reinforcing portion according to the present embodiment is realized by a deformation structure of the fitting bracket 320. Referring to FIG. 7A, the thickness of at least one of both side portions of the fixing bracket 310 is gradually decreased along the first direction d1. That is, the width of the first opening region 310 'of the fixing bracket 310 is gradually widened along the first direction (W3 <W4). The fixing bracket 310 and the fitting bracket 320 according to the present embodiment are preferably made of a metal material including elasticity so as to be deformable by an external force.

Both sides of the fixing bracket 310 can secure the fitting member 320 fitted in the relatively narrow space of the opening region 310 'with a stronger force by a change in the width of the opening region, A gap can be prevented from being formed between the fixing bracket 310 and the fitting bracket 320.

Referring to FIG. 7B, the reinforcing portion is embodied as an elastic member 322 and a button portion 321 for moving the elastic member 322. The button portion 321 is disposed at one end of the fitting bracket 320 and is formed of a push switch. The button portion 321 is pressed by a force moving in the first direction d1 so that the lifting bracket 320 is inserted into the first opening region 310 'of the fixing bracket 310 .

Meanwhile, the elastic member 322 may be formed on one side of the fitting bracket 320. The elastic member 322 is housed in the fitting bracket 320 but protrudes in the second direction d2 when the button portion 322 is pressed. That is, when the fitting bracket 320 is fully inserted into the fixing bracket 310, the elastic portion 322 protrudes and the elastic portion 322 presses the fitting bracket 320 against the fixing bracket 310 So as to be elastically supported. For example, the elastic portion 322 may be a spring.

Accordingly, the gap formed between the fixing bracket 310, the fitting bracket 320, and the support portion 103 is supported by the elastic portion 322, and the relative movement due to the gap can be eliminated .

Referring to FIG. 7C, the reinforcing portion is formed of a reinforcing member 323 formed to fill a part of the second opening region 320 'of the shim member 320. That is, the reinforcing member 323 may be formed on the inner side of both side portions of the fitting bracket 320 facing each other. The reinforcing member 323 may be formed of an elastic material deformable by an external force. The reinforcing member 323 may be formed to be narrower toward the first direction d1, but the present invention is not limited thereto.

The reinforcing member 323 is disposed to fill a gap between the fitting bracket 320 and the fixing bracket 31 and between the fitting bracket 320 and the supporting portion 103. Accordingly, relative movement between the support portion 103, the fitting bracket 320, and the fixing bracket 310 can be prevented.

According to the embodiments of the present invention including the reinforcing portion, it is possible to fix the body to the wall in a more stable manner by compensating for errors occurring in the manufacturing process of the components of the fixed structure made of the individual components.

Further, since the reinforcement portion is formed to support the gap, damage to the main body due to vibration generated from the outside can be minimized.

8A and 8B are conceptual diagrams for explaining a fixing structure according to another embodiment.

Referring to FIG. 8A, the fixing bracket 410 extends in a predetermined length along the third direction d1. Since the fixing bracket 410 according to the present embodiment is substantially the same as the fixing bracket 310 of FIG. 3A except for the length, a duplicated description will be omitted. The fixing structure according to the present embodiment includes first and second fitting brackets 320a and 320b. The first and second fitting brackets 320a and 320b have substantially the same shape.

The first and second fitting brackets 320a and 320b are fitted in the fixing bracket 410 and the second space 104b and move in opposite directions. The third opening regions 410 'of the fixing bracket 410 according to the present embodiment are formed to have a narrower width in a direction away from each other. The structure of the fixing bracket 410 will be described in detail with reference to FIGS. 8B and 8C.

 8B and 8C are conceptual diagrams for explaining the structure of the fixing bracket according to another embodiment. The third opening area 410 'of the fixing bracket 410 is formed with a first area A1 having a fifth width w5 and a sixth width w6 narrower than the fifth width w5. 2 area A2. A second region A2 is formed with the first region A1 interposed therebetween.

The first and second fitting brackets 320a and 320b move to the second area A2 and are stably inserted into the third opening area 410 '. The width of the third opening region 410 'may be realized by changing the thickness of the fixing bracket 410. That is, the fixing bracket 410 may be formed thicker toward the second area A2 with respect to the first area A1.

 Accordingly, the user can easily fit the fitting bracket to the first region A1 and move the fitting member in both directions, thereby firmly connecting the fitting bracket and the fixing bracket.

The display device including the fixed structure described above can be applied to a configuration and a method of the embodiments described above in a limited manner, but the embodiments can be applied to all or some of the embodiments As shown in FIG.
