DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the aspects of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The aspects are described below in order to explain the present invention by referring to the figures.
FIG. 2 is a perspective view of a display apparatus according to a first embodiment of the present invention, and FIG. 3 is an exploded perspective view of a stand structure of the display apparatus according to the first embodiment of the present invention. FIGS. 4A and 4B are partial cross sectional views of the stand structure according to a lifting operation of a monitor of the display apparatus according to the first embodiment of the present invention.
As shown therein, the display apparatus according to an embodiment of the present invention comprises a monitor 20, and a stand 30 coupled to a rear surface of the monitor 20 to support the monitor 20.
The monitor 20 implements a function of displaying a picture on a display panel, and is coupled firmly to the stand 30 by various coupling devices, such as, for example, a screw.
The stand 30 comprises a supporting member 40, an inner slider 50 accommodated to be liftable up and down in an inside of the supporting member 40, an outer slider 60 provided on an outer circumferential surface of the supporting member 40 to be movable by a magnetic cooperation with the inner slider 50 and to connect to the monitor 20, and an elastic member 70, provided on a bottom of at least one of the inner slider 50 and the outer slider 60, to support the monitor 20 elastically.
The supporting member 40 comprises a base 42 placed on a floor surface of a place where the display apparatus is located on, and a supporter 44 formed with an inner space. The base 42 is divided into an upper body and a bottom body of a mutually-removable plate shape. The supporter 44 is made of non-magnetic material with high durability such as aluminum to facilitate a lifting movement.
The base 42 and the supporter 44 may take various sizes and shapes as necessary.
Also, a top end of the supporter 44 of the supporting member 40 is opened to accommodate the inner slider 50 and the elastic member 70, and a deviation prevention cap 46 is coupled on an opened part to prevent deviation of the inner slider 50.
At least one of the inner slider 50 and the outer slider 60 comprises a magnet to interlock each other by the magnetic cooperation. In other words, at least one of the inner slider 50 and the outer slider 60 is provided with a permanent magnet generating a magnetic force, while the other is made of magnetic material magnetized by the magnetic force generated from the permanent magnet.
The inner slider 50 comprises an inner sliding block 52 accommodated liftably in the supporter 44 of the supporting member 40, and an inner magnet 54 connected to the inner sliding block 52 to contact an inner surface of the supporter 44 of the supporting member 40 to generate the magnetic force. The inner sliding block 52 is formed with a locking protrusion to be supported by the elastic member 70. The number of the inner magnets 54 to be installed may be adjusted properly.
Also, the inner slider 50 may take various structures as long as the inner slider 50 magnetically cooperates with the outer slider 60. As an example, the inner slider 50 can be made of the permanent magnet except for the inner magnet 54.
As shown in FIGS. 4A and 4B, an outside of the inner sliding block 52 includes at least one magnet accommodation groove 53, and the inner magnet 54 is accommodated in the magnet accommodation groove 53 of the inner sliding block 52. The inner magnet 54 has a ring shape, and a shape of the corresponding magnet accommodation groove 53 matches the shape of the inner magnet 54.
The outer slider 60 comprises an outer sliding block 62 having a hollow to couple with an outer surface of the supporter 44 of the supporting member 40, and an outer magnet 64 accommodated in the outer sliding block 62 to be supported by the outer surface of the supporter 44 of the supporting member 40 by the magnetic cooperation with the inner magnet 54 of the inner slider 50. The outer magnet 64 moves the sliding block by the magnetic cooperation with the inner magnet 54, and the number of the outer magnet 64 to be installed may be adjusted as necessary.
The outer slider 60 may have various structures as long as the outer slider 60 maintains a magnetic cooperation with the inner slider 50. As an example, the outer slider 60 may be made of the permanent magnet except for the outer magnet 64.
An inside of the outer sliding block 62 is formed with at least one magnet accommodation groove 63, and the outer magnet 64 is accommodated in the magnet accommodation groove 63 of the outer sliding block 62. The outer magnet 64 has a ring shape, and the corresponding magnet accommodation groove 63 is similarly shaped to substantially match the shape of the outer magnet 64.
Meanwhile, the inner magnet 54 and the outer magnet 64 mutually attract each other by the magnetic cooperation with the supporter 44 of the supporting member 40 between the inner magnet 54 and the outer magnet 64. The inner magnet 54 and the outer magnet 64 have magnetic force between them, which is strong enough to overcome elastic force generated when the elastic member 70 is compressed (i.e. as a result of being pushed down by a user), and are closely supported on the inner surface and the outer surface of the supporter 44 of the supporting member 40, respectively.
In other words, due to the attractive force between the inner magnet 54 and the outer magnet 64, a frictional force is generated between both the inner slider 50 and the outer slider 60 and the supporting member 40. This frictional force is sufficient to prevent a decompression of the elastic member 70 when a user no longer pushes down the elastic member 70. Of course, this effect would also apply in a case in which the elastic member is extended, and subsequently released. In this case, the frictional force would prevent a compression of the elastic member.
In an embodiment of the invention, the elastic member 70 is included in a lower part of the inner slider 50 to prevent the elastic member 70 from being exposed. However, the elastic member may be included in a lower part of the outer slider 60 as necessary. Also, the elastic member 70 may be selected from among various kinds of disclosed elastic members having an elastic force strong enough to support a weight of the monitor 20. However, the advantage of the use of a compressing spring is that the compressing spring has a relatively simple structure and provides functionality.
In an embodiment of the invention, the supporter 44 of the supporting member 40 has a cylindrical structure to realize both a lifting movement and a rotating movement of the monitor 20 at substantially the same time by lifting and rotating the outer slider 60. Also, the supporter 44 may have a polygonal structure where only the lifting movement of the monitor 20 is enabled. Accordingly, the shapes of the inner slider 50 and the outer slider 60 may vary according to the structure of the supporter 44.
In an embodiment of the invention, the outer slider 60 is coupled as an annular structure to surround the outer surface of the supporter 44 of the supporting member 40 in consideration of the magnetic force and stability.
Reference numbers 82 and 84 indicate a tilting bracket and a pivot bracket, respectively, and a detailed description on those will be presented later with reference to FIGS. 5A, 5B, and 5C.
Hereinbelow, an operation of the stand of the display apparatus will be described.
Firstly, if a user applies constant force to push the monitor 20 down, the outer slider 60, connected to the monitor 20, moves downward slidingly along the outer surface of the supporter 44 of the supporting member 40. Accordingly, the inner slider 50, installed to be interlocked by the magnetic cooperation with the outer slider 60, moves downward slidingly along the inner surface of the supporter 44 of the supporting member 40 as the inner slider 50 compresses the elastic member 70 provided in a lower part thereof at the same time.
Herein, the elastic member 70 blocks unexpected movement of the inner slider 50 and the outer slider 60 caused by the weight of the monitor 20.
Also, if the user stops the monitor 20 at a position where he/she wants, the monitor 20 is maintained in a stationary state by a supporting force of the elastic member 70 and the frictional forces generated as a result of the magnetic forces of the inner slider 50 and the outer slider 60. Herein, as the elastic force of the elastic member 70 is designed to be blocked by a pressing force of the inner slider 50 and the outer slider 60 relative to the inner surface and the outer surface, the inner slider 50 and the outer slider 60 may constantly maintain the stationary state unless an additional external force is applied to the monitor 20.
Meanwhile, as the outer slider 60 is installed to be rotatable along the outer surface of the supporter 44 of the supporting member 40 having a cylindrical structure, the outer slider 60 may rotate in 360 degrees along the outer surface of the supporter 44 of the supporting member 40 when the user enables the rotational movement of the monitor 20.
FIGS. 5A, 5B, and 5C illustrate operation states of the monitor of the display apparatus according to the embodiment of the present invention.
As shown therein, the display apparatus according to the embodiment of the present invention controls the lifting movement and the rotating movement of the monitor 20 freely according to the sliding movement of the outer slider 60. Also, since a rotating bracket 80 is additionally connected to the outer slider 60 and the monitor 20, the monitor 20 may rotate.
The rotating bracket 80 comprises a tilt bracket 82 installed on an outside of the outer slider 60 to enable the monitor 20 to tilt, and a pivot bracket 84 connected to a first side of the tilt bracket 82 and coupled to the monitor 20 to enable the monitor 20 to pivot.
The tilt bracket 82 and the pivot bracket 84 may be selectively installed according to a purpose and a utility of the display apparatus. Also, a structure thereof may be applied with various disclosed structures.

The second embodiment of the present invention shares an operating principle and a comprehensive structure with the first embodiment of the present invention. Hereinbelow, descriptions of identical components will be skipped, and components of the second embodiment different from those of the first embodiment will be described.
As shown in FIG. 7, the inner slider 50 comprises an upper supporter 52 a, a lower supporter 52 b coupled to the upper supporter 52 a, and more than one inner magnet 54 installed between the upper supporter 52 a and the lower supporter 52 b. Also, in an embodiment of the invention, a spacer 55 is provided between the inner magnets 54.
The upper supporter 52 a and the lower supporter 52 b are screw-combined, and provided with flanges 56 a and 56 b, respectively, to prevent the inner magnet 54 from deviating. Particularly, the flange 56 b of the lower supporter 52 b supports the elastic member 70 at the same time.
The outer slider 60 comprises the outer sliding block 62, formed with a hollow, to be coupled with the outer surface of the supporter 44 of the supporting member 40, more than one outer magnet 64 accommodated into the hollow of the outer sliding block 62 and closely supported by the outer surface of the supporter 44 of the supporting member 40 by the magnetic cooperation with the inner magnet 54, and deviation prevention members 61 a and 61b coupled to upper and lower parts of the outer sliding block 62 and preventing the outer magnet 64 from deviating from a magnetic cooperation with the inner magnet. In an embodiment of the invention, the spacer 65 is provided between the outer magnets 64.
The deviation prevention members 61 a and 61 b are coupled to the outer sliding block 62 by a coupling device 69 such as, for example, a screw, and the coupling device 69 may employ various coupling methods as necessary. Also, a top end of the deviation prevention member 61 is coupled with the deviation prevention cap 46 to prevent the outer slider 60 from deviating from the supporter 44 of the supporting member 40.
Meanwhile, the outer sliding block 62 is installed with the rotating bracket 80 to enable the monitor 20 to rotate. The rotating bracket 80 comprises the tilt bracket 82, installed on the outside of the outer slider 60, to enable the monitor 20 to tilt, and the pivot bracket 84, connected to a first side of the tilt bracket 82 and coupled to the monitor 20, to enable the monitor 20 to pivot.
FIG. 9 is a partial cross sectional view of a structure of the stand of the display apparatus according to a third embodiment of the present invention.
As shown therein, the display apparatus according to the embodiment of the present invention comprises the monitor 20, and the stand 30 coupled to the rear surface of the monitor 20 and supporting the monitor 20.
Particularly, the stand 30 comprises the supporting member 40, and the outer slider 60 provided on the outer surface of the supporting member 40 to be movable by the magnetic cooperation with the supporting member 40.
The supporting member 40 comprises the base 42, and the supporter 44 perpendicularly installed on the base 42.
One of the supporter 44 of the supporting member 40 and the outer slider 60 is made of the permanent magnet generating the magnetic force, and the other of the supporter 44 of the supporting member 40 and the outer slider 60 is made of the magnetic material magnetized by the magnetic force generated from the permanent magnet.
The outer slider 60 comprises the outer sliding block 62 coupled to the outer surface of the supporter 44 of the supporting member 40, and the outer magnet 64 accommodated into the outer sliding block 62 and supported on the outer surface of the supporter 44 of the supporting member 40.
The outer slider 60 may have various structures as long as the outer slider 60 can have the magnetic cooperation with the inner slider 50. As an example, the outer slider 60 may be made of the permanent magnet.

The outer magnet 64 has a ring shape, and the magnet accommodation groove 63 has a shape which corresponds to a shape of the outer magnet 64.
Also, the outer slider 60 generates the magnetic force strong enough to lift the monitor 20 up and down along the supporter 44 of the supporting member 40 while supporting the monitor 20 firmly. In a case that the magnetic force of the outer slider 60 is not strong enough to support the monitor 20, the elastic member 70 such as the compressing spring is provided separately in a lower part of the outer slider 60 to maintain the outer slider 60 stationary according to the lifting movement of the monitor 20.
The elastic member 70 is provided in a case 72 retractable by the elastic force of the elastic member 70 in consideration of the appearance.
