The ratchet wheel 62 penetrates a center thereof and communicates with the fourth through hole 32 of the third frame 30. The ratchet wheel 62 penetrates through the center of the ratchet wheel 62 such that the bolt of the second shaft member 40b ( 42) is fixed.

The pawl 64 is engaged with the ratchet wheel 62 while being secured to the second frame 20 or spaced apart from the ratchet wheel 62. The torsion spring 66 is installed between the pole 64 and the second frame 20 as shown in FIG. 3. Accordingly, the pole 64 receives a torsional force in an upward direction, and when no external force is applied. The ratchet wheel 62 is held in engagement.

When the pawl 64 is engaged with the ratchet wheel 62 as described above, since the downward rotation of the ratchet wheel 62 is constrained, when the third frame 30 needs to be rotated downward, the user directly poles. The third frame 30 is rotated while the 64 is spaced apart from the ratchet wheel 62. On the contrary, when the third frame 30 is rotated upward, the third frame 30 may be rotated without manipulating the pole 64.

On the other hand, the buffer member 50a is inserted into the third through hole 24 and the fourth through hole 32 which are in contact with each other. Such a buffer member 50a is formed of a hollow cylindrical body, and the second shaft member 40b. The bolt 42 constituting the insert is to be inserted. In addition, the shock absorbing material 50a is formed such that the protruding pieces 52 are formed around the center portion of the outer circumferential surface so that the second frame 20 having the third through hole 24 and the third frame having the fourth through hole 32 formed therein ( 30) to be connected with the protrusion piece 52 in between.

The shock absorbing material 50a has the same structure and function as the shock absorbing material 50a provided between the first frame 10 and the second frame 20.

On the other hand, the third frame 30 is coupled to the fixed plate 220 is formed on the back of the wall-mounted TV 200, for this purpose, the fixed end 34 of the circular cross section protrudes to the front end surface of the third frame 30 The fixing plate 220 has a fixing hole 222 of a circular cross section corresponding to the fixing end 34.

The fixing end 34 of the third frame 30 is rotatably inserted into the fixing hole 222 of the fixing plate 220 so that the fixing plate 220 is in the roll direction as shown in FIG. To rotate.

Here, in the preferred embodiment of the present invention, the bearing 240 is inserted into and fixed to the fixing hole 222 of the fixing plate 220 so that the fixing end 34 of the third frame 30 is engaged with the bearing 240. Roll rotation of the 220 is to be made smoothly.

In addition, in the preferred embodiment of the present invention as shown in Figure 4 (b) is provided with a ring-shaped hollow cushioning material (50b) is inserted into the fixed end 34. The shock absorbing material 50b is positioned between the third frame 30 and the fixing plate 220 so that the third frame 30 and the fixing plate 220 are in close contact with the shock absorbing material 50b, respectively. ) Is made of a urethane material having the same flexibility and elasticity as the shock absorbing material (50b) is inserted into the third frame 30 and the fixed plate 220 by providing a predetermined amount of friction force such a cushioning material (50b) is flexible and elastic It is made of a urethane material to provide a predetermined size of the friction force to prevent the random rotation of the fixed plate 220 to control the rotation of the roll direction of the fixed plate 220. That is, when the external force of a predetermined size or more by the user does not act on the fixed plate 220, the fixed plate 220 is to maintain the current position.

In addition, the shock absorbing material 50b prevents the third frame 30 and the fixed plate 220 from directly contacting each other to prevent the occurrence of noise, and is made of a urethane material having flexibility and elasticity to absorb vibrations. It also plays a role in preventing occurrence.
