FIG. 9 is a cross-sectional view taken along the line II-II 'of FIG. 7, which is a cross-sectional view illustrating a movable hinge coupled state in an upright state, and FIG. 10 is a perspective view illustrating an internal coupled state of the movable hinge in FIG. 9 state. .

9 and 10, the stand 22 of the support device 20 according to the present invention maintains an upright state according to the position of the movable hinge 274 fitted to the supporter 27 or the base ( 21) It should be folded tightly.

In detail, the movable hinge 274 has a hinge body 274a having a predetermined diameter and length, and a locking portion 274b having a diameter larger than the hinge body 274a on one side of the outer circumferential surface of the hinge body 274a. Is made of.

In addition, a hinge hole 271 is formed in the supporter body 271 of the supporter 27 to accommodate the hinge body 274a and the locking portion 274b. The movable hinge 274 is inserted through the stand 22 and the supporter body 271. Thus, when the stand 22 is folded while rotating, the movable hinge 274 also rotates together. The hinge hole 271 is curved to have the same curvature as the curvature drawn when the movable hinge 274 rotates.

In detail, the hinge hole 271 is equal to or larger than the third guide hole 273c in which the hinge body 274a is accommodated, and the third guide hole 273c from an end of the third guide hole 273c. The second guide hole 273b is formed to have a diameter, and the first guide hole 273a is formed to have the same diameter as the locking portion 274b from the end of the second guide hole 273b.

Here, the third guide hole 273c is formed to have the same diameter as the hinge body 274a of the movable hinge 274 to guide the hinge body 274a to rotate without oscillation. The second guide hole 273b is formed to have a diameter equal to or larger than that of the hinge body 274a. In summary, the first guide hole 273a is larger than the second and third guide holes 273c and 273b.

In addition, an expansion pipe portion 273d (see FIG. 12) having the same diameter as the locking portion 274b is formed at a lower end portion of the second guide hole 273b. A portion of the second guide hole 273b other than the expansion portion 273d is formed to have a diameter equal to or larger than that of the third guide hole 273c as described above. Therefore, the movable hinge 274 does not rotate in the state where the locking portion 274b is inserted into the expansion pipe 273d, so that the stand 22 is maintained in an upright state.

In detail, a spring 275 is inserted into the outer circumferential surface of the movable hinge 274, and a groove for accommodating the spring 275 is formed in the stand 22. Therefore, when the stand 22 is upright, the locking portion 274b is pushed by the elastic force of the spring 275 and inserted into the expansion pipe 273d. In addition, since the second guide hole 273b extending above the expansion portion 273d is smaller than the diameter of the expansion portion 273d, the movable hinge 274 cannot rotate.

Meanwhile, in the above description, three hinge holes 273 having different sizes are connected to one, but the third guide hole 273c and the second guide hole 273b have diameters of the hinge body 274a. It can be formed to be curved to the same diameter as.

In other words, the hinge hole 273 includes a locking guide hole for receiving the locking portion 274b to guide rotation, a hinge body guide hole for receiving the hinge body for guiding rotation, and the hinge body guide. The lower end of the hole may be formed of an expansion pipe formed with the same diameter as the locking portion. By this structure, the rotation of the stand is blocked in the state that the engaging portion is inserted into the expansion pipe. This is because the upper portion of the expansion portion extends a hole having the same size as the diameter of the hinge body 274a. On the other hand, in the state in which the locking portion is inserted into the locking guide hole, the movable hinge 274 is rotatable along the hinge hole 273, so that the stand 22 can be folded.

FIG. 11 is a cross-sectional view taken along the line II-II 'of FIG. 7, and is a cross-sectional view illustrating a movable hinge coupling state when a stand folding process is performed, and FIG. 12 illustrates an internal coupling state of the movable hinge in FIG. It is a perspective view showing.

11 and 12, in order for the stand 22 to be folded, the locking portion 274b of the movable hinge 274 should be positioned in the first guide hole 273a.

In detail, the first guide hole 273a is formed to have the same diameter as the locking portion 274b. Then, in order to fold the stand 22, the user presses one end of the movable hinge 274, that is, the opposite end of the side on which the spring 275 is fitted. Then, as the spring 275 is contracted, the locking portion 274b inserted into the expansion pipe 273d moves toward the first guide hole 273a. When the user rotates the stand 22 in this state, the movable hinge 274 rotates while the locking portion 274b is fitted into the first guide hole 273a. In addition, while the movable hinge 274 rotates, the user does not return the movable hinge 274 to its original position even when the user removes the force applied to the movable hinge 274. This is because the second guide hole 273b adjacent to the first guide hole 273a is smaller than the diameter of the locking portion 274b.

On the other hand, it is not limited to the hinge means presented above as a means for enabling the stand 22 to rotate or stand up, it turns out that various adjustment means can be presented, the main idea of the present invention is that the stand 22 is upright Note again that it can be varied in state or folded state.

In more detail, the rotation control unit 30 has a back plate 31 fixedly coupled to the rear surface of the support plate 25, and a pivot adjusting piece 32 in close contact with the center of the rear surface of the back plate 31. And a tilting adjusting piece 34 coupled to the end of the support arm 24, and a connecting piece 33 connecting the pivot adjusting piece 32 and the tilting adjusting piece 34. The connecting piece 33 is integrally formed with a display side connecting piece 331 coupled to the pivot adjusting piece 32 and an arm side connecting piece 332 coupled to the tilting adjusting piece 34.

In addition, the display side connecting piece 331 and the pivot adjusting piece 32 is coupled by a screw 35, the pivot adjusting piece 32 is fixedly coupled to the back plate 31 by another screw. . Thus, the support plate 25 and the back plate 931 and the pivot adjusting piece 32 are integrally moved, and the pivot adjusting piece 32 is rotatably coupled to the display side connecting piece 331. A bushing 36 is inserted between the pivot adjusting piece 32 and the display side connecting piece 331 so that the pivot adjusting piece 32 is spaced apart from the display side connecting piece 331. In addition, a nut 38 is inserted into an outer circumferential surface of the end portion of the screw 35 so that the screw 35 does not fall out.

In addition, the female side connecting piece 332 is rotatably coupled to the tilting adjustment piece 34 by a screw 35. In addition, a bushing 36 is inserted between the tilting adjusting piece 34 and the female side connecting piece 332 so that the female connecting piece 332 is spaced apart from the tilting adjusting piece 34. In addition, the tilting adjusting piece 34 may be fixed to the support arm 24 by a separate screw member.

By the configuration as described above, the display 11 is capable of pivoting (rotating in the left and right directions) and tilting (rotating) in the front and rear directions.

In addition, a means for preventing the phenomenon caused by the weight of the display 11 during the pivoting and tilting of the display 11 should be taken. Hereinafter, such a waste prevention structure will be described in more detail with reference to the accompanying drawings.

23 and 24 are partial perspective views showing the structure of the rotation control unit for preventing the waste of the display.

Referring to FIGS. 23 and 24, the waste prevention structure of the display 11 is equally applied to both the pivoted part and the tilted part. Hereinafter, the pivoted part will be described as a representative embodiment. .

In detail, in order to prevent a flat phenomenon in the pivoting process of the display 11, the display side connecting piece 331 and the pivot adjusting piece 32 allow the rotation of the display 11 to be controlled by a frictional force.

In more detail, a portion of the display side connecting piece 331 is formed in the cutting groove 331c as shown, and the friction end 331a cut by the cutting groove 331c toward the pivot adjusting piece 32. Bent In addition, a cutting groove 323 is formed in the pivot adjusting piece 32, and the friction end 321 cut by the cutting groove 323 is bent toward the display side connecting piece 331. Accordingly, the friction ends 331a and 321 come into contact with each other during the rotation of the display 11 to generate frictional force.

In addition, a stopper 331b is bent at a lower end of the display side connecting piece 331, and a guide groove 322 is formed at the pivot adjusting piece 32 to limit the amount of rotation of the stopper 331b. Therefore, while the stopper 331b rotates along the guide groove 322, the maximum amount of rotation of the display 11 is controlled.

By the above configuration, when the user rotates the display 11 in the direction of the arrow, the pivot adjusting piece 32 is rotated together. As the pivot jaw section 32 rotates, the end of the friction end 321 rotates while being in contact with the surface of the friction end 331a of the display side connection piece 331. As the amount of rotation of the display 11 increases, frictional force generated between the friction ends 321 and 331a increases. Therefore, the phenomenon of being idle due to the weight of the display 11 in the state in which the display 11 is rotated is prevented. In addition, since the maximum amount of rotation of the display 11 is controlled by the stopper 331b, the display 11 can be safely rotated.

According to the display support device according to the present invention having the above configuration, even when a user using a laptop computer uses a separate display device, the laptop computer can be positioned directly below the display device, thereby providing convenience for the user. This has the effect of being planned.

In addition, the display support device according to the present invention has the effect of minimizing the volume when transporting or packaging because of the convenience of folding.

In addition, the display support apparatus according to the present invention has the advantage that the display can be rotated 360 degrees in front and rear, so that the opposing opponent can see the display screen without moving the seat.
