Hinge devices for LCD monitor

The present invention relates to a hinge device used in the LCD monitor, and more particularly to a hinge device that maintains a constant angle even if the angle of the hinge frame is changed.

Typically, a hinge device of a liquid crystal monitor, which has been widely used in a computer, has a monitor stand 101 and a monitor 104 formed of a substrate 102 and a support rod 103, as shown in FIGS. 1 and 2. And a structure used to fix the support rod 103 to the first hinge 105 and the substrate 102, which are friction hinge structures of a torsion spring type capable of operating the monitor 104 up and down. The two hinges 106 are coupled to each other.

The first hinge 105 is composed of a housing 107, a rotating shaft 108, and a torsion spring 109 for operating the monitor 104 up and down, and the housing 107 has an axial hole 110. ) And a fixed slot 111 is provided below.

In addition, the rotating shaft 108 is coupled to the first shaft portion 112 inserted into the axial hole 110 of the housing 107, the second shaft portion 113 and the second shaft portion 113 connected to the end thereof, It consists of a fixing part 114 extending to the opposite side of the one shaft portion 112, and is configured to be coupled to the monitor 104 by the fixing part 114.

The torsion spring 109 is formed of a plurality of clip-shaped leaf springs and is inserted into the housing 107 in the axial hole 110 of the housing 107 together with the rotation shaft 108 while being pressed against the rotation shaft 108. It is fixed.

In addition, the second hinge 106 is fastened with a washer 116 and a nut 117 so that the fixing shaft 115 for fixing the support rod 103 to the substrate 102 is rotatable.

Therefore, when the second hinge 106 is used, the support rod 103 is rotatably fastened so that the monitor 104 can be rotated left and right.

However, the hinge device having the structure as described above is configured to simply rotate the monitor to the left, right or up and down, so that the monitor is always positioned at a certain height, so that the eye level with the monitor does not match with the user so that it can work for a long time. If the eye fatigue is increased, work efficiency is reduced, and there is a problem such as impaired eyesight.

Therefore, in order to solve the above problems, the present invention can adjust the height of the monitor and keep the angle of the monitor vertically, thereby eliminating eye strain and thereby improving the working efficiency. The purpose is to provide a hinge device for the purpose.

The present invention for achieving the above object is a tilt body coupled to the upper hinge frame, the monitor stand is coupled to the tilt shaft on both sides of the tilt body, and the tilt shaft is fixed to the substrate is coupled to both sides of the hinge frame lower A push rod that is attached to the down stand and the tilt body on both sides of the hinge frame by a push pin to maintain the monitor vertically even when the hinge frame slides up and down, and is provided on one side of the push rod to support the hinge frame. It is achieved by providing a hinge device, characterized in that consisting of a compression spring.

11a to 11c is a state diagram used in the present invention.

The present invention has a hinge frame 10 is formed in each of the insertion piece (10a) and the guide hole (10b) and the fastening hole (10c) formed on the upper both sides, and the tilting shaft is seated on the insertion piece (10a) The downstand 11 to be fastened by the 17a, the tilt body 12 to be fastened by the push pin 18a to the fastening hole 10c of the hinge frame 10, and the tilt body 12 The monitor stand 13 which is fastened by the tilt shaft 17 to both sides to fix the monitor 30, and the upper and lower portions of the hinge frame 10 on both sides of the guide hole 10b and the tilt body 12, respectively. The push rod 14 to be fastened to the compression spring 15 is formed to be in close contact with the push rod 14 in the central portion of the hinge frame 10.

The down stand 11 has a groove 11a formed at the center thereof so that the tilt shaft 17a is inserted, and the clip spring 19 is inserted into the inner circumferential surface of the groove 11a and the outer circumference of the tilt shaft 17a. .

In addition, the clip spring 19 is inserted into the inner circumferential surface of the monitor stand 13 and the outer circumferential surface of the tilt shaft 17.

The tilt body 12 has grooves 12a formed at both sides thereof so that the tilt shaft 17 is inserted therein, and the hinge frame 10 and the tilt body 12 are fastened with push pins 18a on the front surface thereof. A fork support piece 12b is formed and an actuating piece 12c is formed to be fastened to the push rod 14 and the push pin 18 on the rear surface.

The push rod 14 has a lower portion of the guide hole 10b fastened to the hinge body 16 and an upper portion of the push rod 14 fastened to the tilt body 12 by the push pin 18.

The substrate 20 is fixed to the bottom surface of the down stand 11, and the monitor 30 is fixed to the rear surface of the monitor stand 13.

The compression springs 15 are symmetrically installed on both sides in order to balance left and right forces.

11A to 11C of the present invention having the structure as described above, the downstand 11 is fixed on the substrate 20 to support the hinge device, and the monitor 30 supports the monitor stand ( When the monitor 30 is lifted upward while being fixed to 13, the hinge frame 10 is slid upward with the tilt shaft 17a as a central axis.

At this time, the push rod 14 coupled to both sides of the tilt body 12 is guided downward along the guide hole 10b formed in the hinge frame 10, and the push rod 14 is guided and the tilt body 12 and the monitor stand 13 are rotated in a counterclockwise direction so that the monitor stand 13 fastened to both sides of the tilt body 12 is vertical while only the height of the monitor 30 is varied. Will be maintained.

On the contrary, when the monitor 30 is lowered to lower the height of the monitor 30, the hinge frame 10 fastened to the downstand 11 by the tilt shaft 17a is centered on the tilt shaft 17a. It is axially slid downward, the push rod 14 is guided upward along the guide hole (10b) formed in the hinge frame 10, at the same time the tilt body 12 and the monitor stand 13 By rotating the clockwise direction, the monitor stand 13 fastened to both sides of the tilt body 12 is kept vertical and only the height of the monitor 30 is changed.

Meanwhile, the compression spring 15 pushes the push rod 14 downward and pushes the hinge frame 10 upward.

At this time, since the push rod 14 is supported by the downstand 11, the compression spring 15 has a force to push up the hinge frame 10 upwards and thus moves up and down in proportion to the weight of the monitor 30. The force remains constant.

As the push rod 14 is guided, the tilt body 12 and the monitor stand 13 are rotated so that the monitor 30 can be varied according to the height of the user, thereby eliminating eye strain. Work efficiency will be improved.

In addition, even if the height of the monitor 30 is variable, the monitor 30 maintains a constant angle, it is possible to perform a convenient operation.

The present invention is not limited to the above-described specific preferred embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, the present invention can adjust the height of the monitor up and down, so that the monitor can be positioned according to the height of the user can minimize eye fatigue during excessive work, thereby improving work efficiency.

In addition, since the monitor maintains a constant angle even if the height of the monitor is adjusted, there is a convenient effect in use.
