The lower end of the second connecting arm member 40 is coupled to the rear of the actual monitor 50, the monitor coupling bracket 44 for adjusting the vertical angle of the monitor 50 is connected.

Here, the lower end of the second connection arm member 40 may be integrally formed with the monitor coupling bracket 44 or by the connection structure of the horizontal angle adjustment arm 20A and the first connection arm member 20B. It may be formed in a mutually separated form.

Referring to FIG. 3, the first rotation gear 66 is pivotally coupled to the rotation shaft receiving holes 14a formed at both ends of the first vertical angle setting portion 14. The fastening protrusion 22 formed on the upper surface 20a of the first connection arm member 20B is fastened to the fastening hole 66a formed at a predetermined position of the first rotary gear 66 (ie, see FIG. 4A). ).

On the upper side of the first rotary gear 66, a rod-shaped member penetrating the inside of the first arm member 12 from the first vertical angle setting portion 14 to the second vertical angle setting portion 16 ( The first rack gear 62 is engaged with the first rack gear 62 fastened to one end of the 60, and the first rack gear 62 is located inside the first vertical angle setting portion 14 as shown in the planar structure of FIG. Combined so as not to change position.

The first arm member 10 has a first through hole 110A through which a power and a signal line (not shown) connected to the monitor 50 pass, and the rod member 60 is formed. A second through hole 100B is formed to pass through.

An annular fixing member 68 is accommodated in a predetermined position within the first arm member 10, and the fixing member 68 is provided with a guide protrusion 68a having a predetermined height toward the inside thereof.

Correspondingly, a tension supporting member 70 for supporting a threaded portion formed at a predetermined position of the rod-shaped member 60 is housed inside the fixing member 68, and above the tension adjusting member 70. A long groove 70a is formed in which the guide protrusion 68a is accommodated, and a thread shape is formed inside the tension support member 70 so that the threaded portion of the rod-shaped member 60 is engaged.

In addition, an elastic spring 72 for tension adjustment is provided on the outer side of the rod-shaped member 60 between the expansion end portion defined at one side of the tension adjustment member 70 and the other end of the first vertical angle setting portion 14. And a tension for adjusting the tension of the elastic spring 72 by rotating the rod-like member 60 in a left or right direction at one end of the rod-shaped member 60 on the side of the first vertical angle setting portion 14. The adjusting screw 64 is installed.

In addition, the second rotary gear 78 has a second rotational gear 78 formed on both sides of the second vertical angle setting unit 16 similarly to the first rotary gear 68. The upper surface 40a of the second connecting arm member 40 is rotatably coupled to the rotation shaft receiving hole 16a formed at the upper surface of the second coupling arm member 40. The fastening protrusion 42 formed in the fastening.

A coupling in which the second rack gear 74 coupled to the other end of the rod-shaped member 60 is disposed on both sides of the second rotary gear 78 inside the second vertical angle setting unit 16. It is fixedly coupled by (76a, 76b).

Here, unlike the first rack gear 62, the second rack gear 74 is designed to be freely displaced in the horizontal direction, and thus the monitor 50 is always at the time of adjusting the angle in the vertical direction. The vertical angle set by the monitor coupling bracket 44 is maintained.

That is, the operation of the hinge device for adjusting the position of the image display monitor according to the preferred embodiment of the present invention will be described with reference to FIGS. 5 and 6. With support, observation of the image is set to maintain an advantageous vertical angle, and the horizontal angle of the monitor 50 is set by rotating the horizontal angle adjusting arm 20A in the horizontal direction with respect to the fixing member 30. .

In this state, as illustrated in FIG. 5, in a state where the first arm member 12 is held horizontally, the first arm member 12 is second vertically centered on the first vertical angle setting unit 14. When the angle setting part 16 is displaced so as to be raised (see FIG. 6) or lowered, the first rotary gear 66 is fastened to the fastening hole 66a of the first connecting arm member 20B. Is rotated to the lifting force (or lowering force) of the first arm member 10, and the second rotary gear 78 also rotates in the same direction as the first rotary gear 66.

The first rack gear 62 and the second rack gear 74 coupled to both ends of the rod-shaped member 60 in conjunction with the rotation of the first rotary gear 66 and the second rotary gear 78 are also shown. 3, the rod-shaped member 60 has the long groove 70a of the tension member 70 in the state where the rod-shaped member 60 is fastened to the inner side of the tension adjusting member 70. It is stably displaced with the support of the guide protrusion 68a of the cylinder 68).

Since the second rotary gear 78 is in the state of such a rising or lowering operation, the fastening protrusion 42 of the upper surface 40a of the second connecting arm member 40 is coupled to the fastening hole 78a. Since the rotary gear 78 has the same rotation angle as the first rotary gear 68 by the rod member 60, the monitor 50 always maintains a fixed vertical angle.

Therefore, according to the hinge device for adjusting the position of the image display monitor of the present invention, even when the vertical angle is adjusted with respect to the monitor 50, the vertical angle of the monitor 50 can be kept constant without change. This eliminates the hassle of having to adjust the viewing angle of the monitor 50 every time the angle in the vertical direction is adjusted.

On the other hand, the present invention is not limited to the above examples and various changes and modifications can be carried out within the scope not departing from the technical gist and gist of the invention.
