DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0044] 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.
[0045] 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.
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] The base 42 and the supporter 44 may take various sizes and
shapes as necessary.
[0051] 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.
[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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.
[0058] 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.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] 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.
[0063] 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.
[0064] 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.
[0065] Hereinbelow, an operation of the stand of the display
apparatus will be described.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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.
[0070] FIGS. 5A, 5B, and 5C illustrate operation states of the
monitor of the display apparatus according to the embodiment of the
present invention.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] FIG. 6 is a perspective view of the display apparatus
according to a second embodiment of the present invention, and FIG.
7 is an exploded perspective view illustrating a structure of the
stand of the display apparatus according to the second embodiment
of the present invention. FIGS. 8A and 8B are partial cross
sectional views of a structure of the stand according to the

[0078] The upper supporter 52a and the lower supporter 52b are
screw-combined, and provided with flanges 56a and 56b,
respectively, to prevent the inner magnet 54 from deviating.
Particularly, the flange 56b of the lower supporter 52b supports
the elastic member 70 at the same time.
[0079] 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 61a 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.
[0080] The deviation prevention members 61a and 61b 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.
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] The supporting member 40 comprises the base 42, and the
supporter 44 perpendicularly installed on the base 42.
[0086] 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.
[0087] 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.
[0088] 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.
[0089] The outside of the outer sliding block 62 is formed with at
least one magnet accommodation groove 63, and the outer magnet 64
is accommodated into the magnet accommodation groove 63 of the
outer sliding block 62. 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.
[0090] 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.
[0091] 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.
[0092] In an embodiment of the invention, the supporter 44 of the
supporting member 40 has a cylindrical structure to enable the
outer slider 60 to lift the monitor 20 up and down and to rotate,
so that the lifting movement and the rotating movement of the
monitor 20 may be realized at a substantially similar time. Also,
the supporter 44 may have a polygonal structure where only the
lifting movement of the monitor 20 is enabled.
[0093] Further, the outer slider 60 is coupled in an annular
structure surrounding the outer surface of the supporter 44 of the
supporting member 40 in consideration of various conditions such as
the magnetic force and the stability.
[0094] Meanwhile, the tilt bracket 82 and the pivot bracket 84 are
included between the monitor 20 and the outer slider 60 to realize
the tilting movement and the pivoting movement.
[0095] As is described above, the display apparatus according to
the embodiment of the present invention realizes the lifting
movement and the rotating movement of a monitor conveniently and
easily by a stand structure using magnetic force.
[0096] Also, a simplified structure of the stand not only improves
an assembling process and productivity, but also minimizes a
malfunction in operation. Accordingly, the display apparatus is
advantageous in a financial aspect because a cost of production can
be saved.
[0097] Although a few embodiments of the present invention have
been shown and described, it will be appreciated by those skilled
in the art that changes may be made in these aspects without
departing from the principles and spirit of the invention, the
scope of which is defined in the appended claims and their
equivalents.
