A horizontal insertion groove 44 is formed horizontally, and an approximately c-shaped insertion groove 40 is formed.

In addition, the insertion groove 46 of the hook member 70, which will be described later, is formed in the lower direction toward the center side of the horizontal insertion groove 44 in the insertion groove 40, and corresponds to the hook member insertion groove 46. The hook groove 48 of the hook member is formed in the upward direction.

One end of the support link member 50 is rotatably coupled to the bottom of the vertical insertion groove 42 in the insertion groove 40 by a hinge.

In this case, the support link member 50 is rotatably coupled to the one-piece link 52 which is rotatably coupled to the bottom of the vertical insertion groove 42, and also rotates about the end of the one-piece link 52 by a hinge. It is preferable that the two-piece link 54 is coupled as possible, but in some cases, may be made of two or more.

Both ends of the link link member 60 are rotatably coupled to the ends of the two-link link 54 of the support link member 50 by a hinge. Here, the connection link member 60 is accommodated with respect to the horizontal insertion groove 44 of the insertion groove (40).

That is, the support link members 50 are accommodated with respect to the vertical insertion groove 42 of the insertion groove 40, and the connection link member 60 is inserted into the horizontal insertion groove 44 of the insertion groove 40. The storage is made.

Therefore, the thickness of the support link members 50 and the connection link member 60 preferably corresponds to or is thinner than the depth of the vertical insertion groove 42 and the horizontal insertion groove 46.

The reason is that a part of the support link members 50 and the link link member 60 protrude from the surface of the case 30 while being inserted into the vertical insertion groove 42 and the horizontal insertion groove 44. To prevent this.

On the other hand, the hook portion 70 of the approximately c-shaped is fixed to the central portion of the connecting link member 60.

Here, the hook member 70, as shown, it is preferable to apply a c shape, but may be applied to a hook shape, such as may be applied in various shapes, such as U shape according to the aesthetic sense.

In addition, it is said that the hook member insertion groove 46 is formed in the downward direction of the center side of the horizontal insertion groove 44 in the insertion groove 40, in the case of the hook member insertion groove 46 of the hook member 70 It may be formed to correspond to the shape.

In addition, the hook groove 48 corresponding to the hook member insertion groove 46 is formed side by side so that only a part of the hook member 70 is inserted, one side of the hook groove 48 is 3a and As in FIG. 6, the stopper 90 is protruded. Here, the stopper 90 is provided with a force projecting into the hook groove 48 by the elastic member 92 inherent in the case 30, and compresses the elastic member 92 when a predetermined external force is applied. While having a configuration that is drawn into the inside of the case (30).

On the other hand, the stopper 80 for holding the connecting link member 60 in the center portion of the horizontal insertion groove 44 is formed protruding, the stopper 80 is also an elastic member 82 inherent in the case 30 Is applied to the inner side of the horizontal insertion groove 44, and when a predetermined external force is applied, the elastic member 82 is compressed while the elastic member 82 is compressed into the case 30.

In addition, below the horizontal insertion groove 44, support jaw (32, 34) is formed in two stages to be supported in a state in which the link link member 60 is caught, a detailed description thereof will be described later do.

Referring to the operation of the LCD monitor device configured as described above are as follows.

The position may be placed at any position as it is located on the side and not visible from the front view.

On the other hand, the LCD monitor device according to the first embodiment of the present invention can also be used for the wall, if you want to use for the wall as described above, as shown in Figure 5, the support link members 50 And the connecting link member 60 is inserted into the vertical insertion groove 42 and the horizontal insertion groove 44 of the insertion groove 40, respectively, and is not exposed to the outside, only the hook member 70 is the hook member insertion groove ( It is good to take out from 46), and to insert into the hook groove 48, rotating 180 degrees.

That is, the hook member 70 is fixed to the connecting link member 60, the connecting link member 60, both ends thereof are rotatably coupled to each support link member 50. Bar, rotating the hook member 70 by 180 degrees is enabled by the rotation of the link link member 60 only.

As such, when the hook member 70 is removed from the hook member insertion groove 46 and rotated by 180 degrees, the hook member 70 is led into the hook groove 48 formed to correspond to the hook member insertion groove 46. The stopper 90 protruding on one side of the) is drawn inward while compressing the elastic member 92 inside the case 30 by the pressing force while friction with the hook member 70, and the hook member 70 is hooked. When fully inserted into the groove 48, the stopper 90 protrudes by the elastic restoring force of the elastic member 92, thereby holding the hook member 70.

Therefore, as shown in Figure 5, the hook member 70 is to be kept in a fixed state protruded to the upper portion of the monitor device bar, the hook member 70 is hooked to a hook such as a wall for wall hanging It becomes usable.

Of course, in this state, the user is also easy to carry around while holding the hanger 70, the convenience of use will be increased.

For reference, it is desirable to form a groove of a predetermined depth in the central portion of the hook member 70 so that the horizontal state of the LCD monitor device is maintained in a state of being caught by a hook such as a wall.

In this state, when not used as a wall mount or a moving means using the hook member 70, the hook member 70 is flipped back with a constant force, and then retracted into the hook member insertion groove 46. Just do it.

That is, when a certain external force is applied to the hook member 70 to bend back, the stopper 90 holding the hook member 70 compresses the elastic member 92 in the case 30 and the hook groove 48 When the hook member 70 is completely disengaged from the hook groove 48, the stopper 90 again moves in the lateral direction of the hook groove 48 by the elastic restoring force of the elastic member 92. It will protrude.

In this state, the hook member 70 may be pulled back into the hook member insertion groove 46.
