Description of the Related Art [0002] A display device is an apparatus for viewing an image, and in recent years, a large number of flat display devices capable of being shaped in a substantially two-dimensional plane have been released. These flat-panel display devices are not only provided with a flat structure but also light weight, so that they are mounted on a wall and are watched more and more. In view of this situation, various types of supporting devices for wall-mounted display devices have been introduced.

The supporting device includes a fixing part fixed to the wall, a device seating part on which the display device is seated, and a connection unit connecting the fixing part and the device seating part. The connection unit is composed of a plurality of links. Accordingly, the display device can be moved forward and backward and swivel left and right with respect to the wall surface by the operation of a plurality of links.

However, according to the conventional support device, since the back and forth movement of the display device is performed by a plurality of links, stress is concentrated on the hinge axis of each link, and the support device may be damaged.

In addition, since the plurality of links are configured to be superimposed, the front-rear width of the support device becomes large, which increases the distance from the wall surface to the display device.

The object of the present embodiment is to propose a supporting device for a display device capable of achieving reduction in product size, unlimited installation position, and simple structure.

According to the proposed embodiment, the fixing portion is located at the middle portion of the supporting device, and the restriction of the mounting position of the supporting device is minimized as each sliding unit is rotated on both sides of the fixing portion. That is, since the fixing portion can be fixed to the narrow wall or the pillar, the mounting position of the supporting device can be varied.

In addition, since the apparatus seating portion can be moved forward by the sliding action of the sliding unit, stress acting on the hinge point of the sliding unit during the rotation of the sliding unit with respect to the height adjusting unit is transmitted to the sliding members There is an advantage that the fear of breakage of the support device is eliminated.

In addition, since the height adjusting unit is configured to move up and down with respect to the fixed portion, a user can easily adjust the height of the display device while the display device is seated in the device seating portion.

In addition, since the minimum moving distance of the height adjusting unit corresponds to the interval between the hooking grooves of the frame, the user can finely adjust the vertical height of the display device, so that the user can position the display device at a desired height Thus, the user's preference can be satisfied.

The first sliding member 310 is formed with a sliding guide 314 for guiding the sliding of the second sliding member 330. The sliding guide 314 is recessed from the outside of the first sliding member 310 toward the inside. The sliding guide 314 is formed in a direction parallel to the sliding direction of the second sliding member 330.

At least a part of the second sliding member 330 is slid while being drawn into the inner space of the first sliding member 310. The second sliding member 330 is formed with a guide receiving portion 332 for receiving the sliding guide 314. The guide receiving portion 332 is recessed from one side of the second sliding member 310. The guide receiving portion 332 is formed in a shape and size corresponding to the sliding guide 314.

A first guide member 320 for guiding the sliding of the second sliding member 330 is provided on the inner side of the first sliding member 310 so as to improve the strength of the first sliding member 310 And a second guide member 340 is provided on the outer side of the second sliding member 330 to interact with the first guide member 320.

In detail, a plurality of coupling protrusions 322 for coupling to the first sliding member 310 is formed on one side of the first guide member 320. The first sliding member 310 is formed with a through-hole 312 through which the plurality of coupling protrusions 322 pass.

A plurality of guide ribs 324 protrude from the other side surface of the first guide member 320. The plurality of guide ribs 324 are spaced apart from each other in a direction perpendicular to the sliding direction of the second sliding member 320. The guide ribs 324 extend in a direction parallel to the sliding direction of the second sliding member 320. The second guide member 340 is formed with a plurality of rib insertion grooves 342 into which the guide ribs 324 are inserted.

A plurality of guide ribs 324 are formed in the first guide member 320 and a plurality of rib insertion grooves 342 are formed in the second guide member 340. However, When the plurality of guide ribs 324 are formed in the first guide member 320, a plurality of rib insertion grooves are formed in the first guide member 320 because grooves are formed between the guide ribs 324, And a plurality of guide ribs may be formed on the second guide member 340.

The first sliding member 310 is provided with a first guide member 320 having a plurality of guide ribs 324 formed therein and the second sliding member 330 is provided with a plurality of rib insertion grooves A plurality of guide ribs are protruded from the first sliding member 310 and a plurality of ribs 330 are inserted into the second sliding member 330. In this case, The groove may be formed as a depression.

3, a sliding limit of the second sliding member 330 is set on a surface 311 of the sliding guide 314 and the first sliding member 310 facing the sliding guide 314, A limit setting guide 317 for setting a limit is established. A first through hole 315 and a second through hole 316 are formed on one side 311 of the sliding guide 314 and the first sliding member 310 to allow the limit setting guide 317 to pass therethrough. .

The second sliding member 330 is formed with an opening 334 through which the limit setting guide 317 passes. The opening 334 is elongated in a direction parallel to the sliding direction of the second sliding member 330. The second sliding member 330 is slid with respect to the first sliding member 310 in a state in which the limit setting guide 317 passes through the opening 334.

The limit setting guide 317 sequentially passes through the first through hole 315, the opening 334, and the second through hole 316. The limit setting guide 317 penetrating the second through hole 316 prevents the limit setting guide 317 from being separated from the through holes 315 and 316 and the opening 334 The fixing member 318 is engaged. In this case, the limit setting guide 317 may be a screw, the fixing member 318 may be a nut coupled to the screw, and the limit setting guide 317 and the fixing member 318 ) Is not limited in structure.

3, when the first end portion 334a of the opening portion 334 contacts the limit setting guide 317 in the course of moving the second sliding member 330 to the left, 330 will no longer slide to the left.

3, when the second end portion 334b of the opening portion 334 is brought into contact with the limit setting guide 317 in the process of moving the second sliding member 330 to the right side, (330) is not slid to the right.

That is, the second sliding member 330 can be slid by a length corresponding to the length of the opening 334, more precisely, a length obtained by subtracting the width of the limit setting guide 317 from the opening 334. Therefore, the forward movement distance of the display device can be adjusted by adjusting the length of the opening 334 according to the type of the display device.

Meanwhile, the rotation guide 350 is rotatably coupled to the tilting friction portion 40. The rotation guide 350 allows the tilting friction portion 40 to rotate with respect to the rotation guide 350 when the display device is moved forward and the distance between the pair of device seating portions 50 is kept constant To move forward.

That is, when the tilting friction portion 40 is not rotated with respect to the sliding units 30, when the pair of sliding units 30 are operated, the distance between the pair of the device seating portions 50 becomes The distance between the pair of device seating portions 50 is kept constant by rotating the tilting friction portion 40 with respect to the rotation guide 350 in order to prevent the rotation.

Since the pair of device seating portions 50 are moved back and forth in a state where the display device is mounted on the pair of device seating portions 50 substantially, The tilting friction portion 40 must be rotated with respect to the sliding unit 30 in order to move back and forth while maintaining the distance between the pair of device seating portions 50.

8 to 10 are views showing the operation of the support device of this embodiment, wherein FIG. 8 is a view showing a forward movement operation of the support device, FIG. 9 is a view for explaining the up and down tilting operation of the support device, Fig. 5 is a view showing the up-and-down movement of the support device. Fig.

1 and 8, a pair of sliding units 30 connected to both sides of the height adjusting unit 20 by pulling the pair of device seating portions 50 forward in the state of FIG. 1, Is rotated with respect to the height adjusting unit (20). The pair of device seating portions 50 are moved forward by the mutual action of the pair of sliding members constituting the respective sliding units 30. That is, each of the second sliding members 330 slides with respect to each of the first sliding members 310.

At this time, the pair of sliding units 30 operate independently of each other. Therefore, the sliding length of the sliding unit associated with the one-seat mounting unit may cause a difference in sliding length due to the sliding unit associated with the other mounting unit.

That is, the vertical distance between the one-seat mounting portion and the wall surface may be the same as or different from the vertical distance between the other seating portion and the wall surface.

Each of the tilting frictional portions 40 rotates with respect to each of the sliding units 30 in the process of moving the respective device seating portions 50 forward. In addition, the independent operation of each sliding unit 30 enables the left and right swiveling operation of the display device installed in the device seating unit 50.

According to the present embodiment as described above, since the device seating portion 50 can be moved forward by the sliding unit 30, when the device seating portion 50 is moved backward as shown in FIG. 1, The front and rear width can be minimized. That is, since the second sliding member 330 is drawn in and out of the inner space of the first sliding member 310, the thickness of the sliding unit 30 can be reduced, .

In addition, since the apparatus seating portion 50 can be moved forward by the sliding action of the sliding unit 30, when the sliding unit 30 rotates relative to the height adjusting unit 20, Stress acting on the hinge point of the unit 30 is dispersed in the sliding members 310 and 330, thereby eliminating the possibility of damage to the supporting device.
