The display device 300 can be roughly classified into a hand-held method that a user can hold and use, and a mounting method that is mainly used in a specific location. The display device 300 of the mounting method has a wall-mounted form hanging on the output surface or a stand 100 type that is placed on the floor or the like by combining the output unit with the stand 100.

In the case of the stand 100 type, it is necessary to adjust the position of the output unit or the viewing direction according to the user's request. To achieve this, the output unit supports a tilt behavior that tilts in the vertical direction of the stand 100, a swivel movement that can be rotated in a direction parallel to the floor horizontal plane, and a structure capable of height adjustment that can adjust height vertically from the floor. Can be.

However, the structure for realizing the tilt behavior, swivel behavior, and height adjustment behavior inevitably occupies a large volume, increases weight, and increases costs due to the addition of parts.

Therefore, a display device 300 having a simple structure that minimizes volume and weight increase while minimizing production cost while implementing the above behaviors is required.

1 is a side view of a display device 300 related to the present invention and FIG. 2 is a plan view of a display device 300 related to the present invention. The display apparatus 300 may be largely composed of an output unit 200 that directly outputs image information and a stand 100 that mechanically fixes the output unit 200.

The output unit includes a display panel for outputting image information, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light emitting diode (OLED) as a display panel. emitting diode, OLED), and the like.

The output unit 200 may specifically include a basic configuration of a front case, a display panel, a backlight unit, a frame, and a rear case. Depending on the display panel, the backlight unit may be omitted, or the front case may be omitted and the panel itself may be exposed to the outside.

The stand 100 may fix the output unit 200 as described above, mount it on the floor, and further implement a physical behavior of tilt, rotation, and height adjustment of the output unit 200. The stand 100 may be used for mounting the above-described output unit 200 as well as other types of members.

The stand 100 of the present invention includes a vertical body 110 extending in the vertical direction, a horizontal body 140 extending in the horizontal direction, and a support 160 located at the bottom of the vertical body 110, and the horizontal body ( The output unit 200 is coupled to the end of 140).

As the vertical moving part 120 vertically moving along the vertical body 110 and the ends of the horizontal body 140 are combined, the horizontal body 140 moves vertically along the vertical moving part 120 as shown in FIG. 1. You can move in the direction. The horizontal body 140 is characterized in that the length is variable, and as shown in FIG. 1, when a plurality of horizontally arranged frames are slidably combined and placed in overlap, the length of the horizontal body 140 is shortened and sliding. The frame can extend in one direction. In order to support the weight of the display unit 200, a frame adjacent to the vertical body 110 is located at the bottom and a frame disposed adjacent to the display unit 200 may be disposed on the top.

The horizontal body 140 illustrated in FIG. 1 has a structure in which three frames are continuously extended, and when the number of frames is increased, the horizontal body 140 may be extended longer.

The portion where the display unit 200 and the horizontal body 140 are connected includes a hinge unit 150 to adjust the direction in which the display unit 200 faces. As shown in FIG. 2, the hinge part 150 may further include a first hinge part that is rotated in the horizontal direction, as well as a second hinge part that is not shown, but is rotatable in the vertical direction.

In addition, it is located at the bottom of the vertical body 110 may further include a rotating portion 130 between the support 160 and. The rotating part 130 may rotate the vertical body 110 to change the direction in which the entire stand 100 faces.

In the stand 100 of the present invention, as shown in FIG. 1, the position of the display unit 200 may be moved in the vertical direction in the vertical direction, and the direction in which the display unit 200 faces may be adjusted as shown in FIG. 2.

The conventional stand 100 has a discomfort such as adjusting the mounted position to be difficult to adjust to satisfy all distances from the user even if the height can be adjusted, or even if it is possible to adjust the height a little in the left and right directions. . In the present invention, even if the position of the support unit 160 is not changed, the display unit 200 can be arranged at a height, distance, and angle desired by the user, thereby increasing convenience in use.

3 is a perspective view showing a vertical body 110 and a horizontal body 140 of the stand 100 according to the present invention. 4A is a cross-sectional view taken along line A-A in FIG. 2, and FIG. 4B is a cross-sectional view taken along line B-B in FIG. 2, showing the structure of the vertical body 110. The vertical moving part 120 may be disposed inside the vertical body 110 and surrounded by the vertical body 110 so as not to be exposed to the outside. However, in order to be connected to the horizontal body 140, a surface facing the display unit 200 by a length corresponding to the length of the vertical moving unit 120 may be opened.

The vertical rail 121 located inside the vertical body 110 extends in the vertical direction and accommodates a vertical roller moving vertically along the vertical rail 121. To prevent the vertical roller 123 from coming off, the inlet portion may be formed smaller than the size of the vertical roller 123, and the vertical roller 123 is vertically inserted by inserting it in the longitudinal direction from the end of the vertical rail 121. It can be combined with the rail 121.

The vertical rail 121 may include a pair symmetrically to the left and right to stably move the vertical moving unit 120. The connecting frame 125 positioned between the vertical rails 121 is coupled to the vertical roller 123 and can move up and down along the vertical rail 121 through the vertical roller 123. The connecting frame is connected to the horizontal body 140 to move the horizontal body 140 in the vertical direction.

Due to the frictional force between the vertical roller 123 and the vertical rail 121, the user moves only when a user applies a force greater than a predetermined size (force greater than the stop friction force). At this time, the vertical movement unit 120 may suddenly move downward in the downward direction by the weight of the display unit 200 coupled to the horizontal body 140.

A gas spring may be further included to support the weight of the display unit 200 to move slowly. The gas spring 126 can be deformed without great force in the tensioning direction, but when a force is applied in the contracting direction, the force is applied in the opposite direction by air in the cylinder of the gas spring 126. That is, the gas spring 126 may support the movement of the vertical moving part 120 in the downward direction to fix the position of the display part 200.

5A is a C-C cross-sectional view of FIG. 2, and FIG. 5B is a D-D cross-sectional view of FIG. 2, showing the structure of the horizontal body 140.

The horizontal body 140 includes a first frame 141 fastened to the connection frame, and the second frame 142 slide-coupled to the first frame 141 can slide in the horizontal direction and the first frame 141 ) And the second frame 142 overlap, the length of the horizontal body 140 decreases, and when the second frame 142 slides, the length of the horizontal body 140 increases. In this embodiment, the length of the horizontal body 140 may be further increased by further including a third frame in addition to the second frame 142, so that the degree of freedom for adjusting the position of the display unit 200 may be increased.

The first frame 141 and the second frame 142 may further include a horizontal rail and a sliding portion 144 moving along the horizontal rail to slide. A slide ball may be used to assist the movement between the sliding portion 144 and the horizontal rail. The slide ball includes a plurality of beads 146 and 147 positioned between the two members, and may include a structure surrounding the beads 146 and 147 so as not to be separated. When the second frame 142 slides, the beads 146 and 147 rotate, and the second frame 142 may move smoothly.

As shown in FIG. 5A, a frame closer to the vertical body 110 may be located at a lower portion, and a frame closer to the display unit 200 may be positioned at an upper side. In order to support the weight of the display unit 200, since supporting the weight from the lower side is more stable than pulling from the upper side, it is preferable that the frame closer to the vertical body 110 is located at the lower side.

FIG. 6A is a cross-sectional view taken along line E-E in FIG. 2, and FIG. 6B is a cross-sectional view taken along line F-F in FIG. 2, showing the hinge portion 150. The hinge part 150 is located at the end of the horizontal body 140 and the display part 200 is directly coupled. The angle of the display portion 200 can be adjusted, and the ball hinge can be rotated in various directions, but the ball hinge has a weak problem in supporting the weight of the display portion 200 and maintaining the angle.

The hinge portion 150 of the present invention may include a first hinge portion and a second hinge portion in which the rotation direction crosses vertically. The first hinge portion includes a first hinge body 152 that rotates around a first shaft 151 extending in a vertical direction, and the second hinge portion is coupled to the first hinge body 152 and extends in the horizontal direction. The second hinge body 157 may be rotated around the second shaft 155. When the angle of the display unit 200 is changed by interlocking the first hinge unit and the second hinge unit, a direction in which the display unit 200 is directed may be adjusted in various directions, such as a ball hinge.

In the drawing, although the first hinge portion rotating in the vertical direction is positioned closer to the horizontal body 140, on the contrary, the first hinge portion may be disposed closer to the display portion 200. The second hinge portion rotates in the vertical direction and may further include a torsion spring 156 to support the weight of the display portion 200. The torsion spring 156 extends both ends of the coil spring to obtain a force by twisting. The elasticity of the torsion spring 156 can prevent the display portion 200 from being tilted downward.

7A is a view showing the support 160 of the stand 100 according to the present invention, and FIG. 7B is a G-G cross-sectional view of FIG. 7A. The support part 160 positioned at the bottom of the vertical body 110 provides a support force to mount the stand 100 on the bottom surface. In particular, as the weight of the display unit 200 is heavier, the support unit 160 having a large weight with a large area may be used to stably support the weight.

When the support unit 160 is stably fixed to the floor, the present invention is supported by moving the support unit 160 to change the position of the display device 300 because the larger the display device 300, the harder the weight. ) And the vertical body 110 may further include a rotating portion 130. Referring to FIG. 7B, the rotating unit 130 may include a swivel member 131 fixed to the floor, a vertical body 110 and a rotating shaft 132 penetrating the swivel member 131, centered on the rotating shaft 132 As the vertical body 110 rotates, the direction in which the display unit 200 faces may be adjusted. A ball bearing 134 may be further included between the vertical body 110 and the swivel member 131 to rotate smoothly when the vertical body 110 is rotated.

If there is no rotation unit 130, the support unit 160 itself must be lifted and moved to a desired position, but a mobile terminal including the rotation unit 130 can adjust the position of the display unit 200 without moving the support unit 160 within a predetermined range. have.

8A is a view showing the clamping portion 170 of the stand 100 according to the present invention, and FIG. 8B is a cross-sectional view taken along line H-H in FIG. 8A. Instead of using the support portion 160 as shown in FIG. 7A, the stand 100 can be supported using the clamping portion 170. The clamping portion 170 occupies a smaller area than the support portion 160, and has a structure in which a top plate such as a desk is picked up so that it does not fall over.

In particular, when adjusting the position and angle of the display unit 200, it may fall in a state where it is not fixed to the floor. However, if the clamping unit 170 is used, the position and angle of the display unit 200 can be more stably adjusted. This embodiment may also include a rotating portion 130 between the clamping portion 170 and the vertical body 110, and the configuration of the rotating portion 130 is similar to the structure of FIG. 7B described above, and thus will be omitted.

The clamping part 170 includes an upper clamping plate 171, a lower clamping plate 172, and a clamping adjustment screw 173 penetrating the lower clamping plate 172. The upper clamping plate 171 has an a-shape as shown in FIG. 8A and is coupled to the rotating part 130 and is bent at an upper surface portion and an upper surface portion contacting an upper surface of a desk or the like, and a first side surface portion that wraps the side surface of the upper plate. Includes. The lower clamping plate 172 includes a lower surface portion 172a facing the upper surface portion, and the lower surface portion 172a abuts the lower surface of the upper plate. The second side portion 172b bent at the lower surface portion 172a is engaged with the first side portion of the upper clamping plate 171, a locking groove is formed in the first side portion, and a second side portion 172b is inserted into the locking groove A locking protrusion may be formed. The locking groove and the locking protrusion are fastened as shown in FIG. 8B, and the upper plate is positioned between the upper clamping plate 171 and the lower clamping plate 172 to be fixed to the upper plate.

A plurality of locking grooves may be formed in the vertical direction and adjusted according to the thickness of the upper plate. However, since it is insufficient to support the weight of the display unit 200 only by the engaging groove, the clamping adjustment screw 173 may be further included. When the clamping adjustment screw 173 penetrates the lower surface 172a of the lower clamping plate 172 and rotates, the clamping adjustment screw 173 moves through the lower surface 172a and when the clamping adjustment screw 173 is topped In close contact with the clamping portion 170 is fixed. The end portion of the clamping adjustment screw 173 may be widened as shown in FIG. 8B so that a large area is contacted with a lower surface of the upper plate.

As described above, according to at least one of the embodiments of the present invention, the configuration for controlling the vertical height adjustment and the horizontal position is minimized, and the volume can be reduced by folding when moving, thereby reducing the volume compared to the extended range.

In addition, according to at least one of the embodiments of the present invention, the range in which the position and angle of the display unit 200 can be adjusted is enlarged as compared to the prior art, so that the user can easily adjust the position and angle.

Further, according to at least one of the embodiments of the present invention, it is easy to adjust the angle of the display unit through the hinge unit rotating in two directions, and it is possible to adjust the position of the display unit without moving the base through the lower rotating unit.

In addition, since the stand 100 can be stably fixed to the top plate, it can be stably fixed when adjusting the position angle of the display unit 200, and has the advantage of being able to be mounted without taking up a large space.
