incorporated herein by reference in its entirety.
BACKGROUND
[0002] 1. Technical Field
[0003] The present invention relates to a wall mount.
[0004] 2. Description of the Related Art
[0005] Flat panel displays, such as TV sets and monitors, employing
LCD, PDP, LED technology, etc., provide the benefit of allowing
efficient use of small spaces, and are fast replacing Braun tube
TV's and monitors. The increase in demand for such flat panel
displays is expected to continue into the future. A flat panel LCD
or PDP TV may often be referred to as a "wall mount TV" and may be
used attached to a wall surface.
[0006] A wall mount, which secures the flat panel display to a wall
surface, is a device that allows a user to adjust the viewing
angle, and consumer demands regarding the wall mount is becoming
more varied. In particular, various consumer demands are focused on
supplementary functions for providing greater convenience and
higher performance, in addition to the main function of the wall
mount.
[0007] A conventional wall mount can be large and heavy, and can be
difficult to install. The structure of the conventional wall mount
may require a worker to secure the bracket of the wall mount using
fastening screws, etc., while carrying the wall mount. Thus, when
installing the wall mount, the aid of another person may be
required, other than the one worker mentioned above. Moreover, the
conventional wall mount may not allow height or levelness
adjustments, so that once the bracket is joined to the wall
surface, etc., using fastening screws, it may be very difficult to
afterwards adjust the height or levelness of the wall mount.
SUMMARY
[0008] An aspect of the invention provides a wall mount that allows
levelness adjustments.
[0009] Another aspect of the invention provides a wall mount that
includes a bracket and a frame, where the frame can be configured

to one side, and a guide part can be formed on the frame to guide
the bracket in such a way that the bracket may be slidably inserted
into the frame from the one side of the frame.
[0010] The guide part described above can include an upper guide
part, which may be formed on an upper portion of the frame, and a
lower guide part, which may be formed on a lower part of the frame
to support the bracket.
[0011] A hole may be formed in each of the upper guide part and the
lower guide part.
[0012] In each of the holes in the upper guide part and the lower
guide part, an internal thread can be formed. Also, the hole of the
upper guide part and the hole of the lower guide part can be formed
diagonally in relation to each other.
[0013] In certain embodiments, the bracket can include an upper
support part and a lower support part. The upper support part may
protrude from an upper outer portion of the bracket and face the
hole of the upper guide part, while the lower support part may
protrude from a lower outer portion of the bracket and face the
hole of the lower guide part.
[0014] On the other side of the frame, a first protruding part and
a second protruding part can be formed, where the first protruding
part may have a hole formed in the first protruding part, and the
second protruding part may be positioned with a distance from the
first protruding part and may have a hole formed in the second
protruding part.
[0015] The bracket can include a first opposing part and a second
opposing part. The first opposing part can be formed on the outward
portion of the bracket, facing the first protruding part, with a
hole formed in the first opposing part. The second opposing part
can be formed on the outward portion of the bracket, facing the

[0038] FIG. 1 is a perspective view illustrating the frame of a
wall mount according to an embodiment of the invention, and FIG. 2
is a perspective view illustrating the bracket of a wall mount
according to an embodiment of the invention. FIG. 3 through FIG. 9
generally illustrate a wall mount according to an embodiment of the
invention. FIG. 10 is a perspective view illustrating the frame of
a wall mount according to another embodiment of the invention, and
FIG. 11 is a perspective view illustrating the bracket of a wall
mount according to another embodiment of the invention. FIG. 12
through FIG. 16 generally illustrate a wall mount according to
another embodiment of the invention.
[0039] In FIG. 1 through FIG. 16, there are illustrated a bracket
10, an outward portion 12 of the bracket, an upper outward portion
14 of the bracket, a lower outward portion 16 of the bracket, an
upper support part 18a, a lower support part 18b, a frame 20, one
side 22 of the frame, the other side 24 of the frame, a guide part
26, an upper guide part 26a, a lower guide part 26b, a hole 27a in
the upper guide part, a hole 27b in the lower guide part, a first
protruding part 28a, a second protruding part 28b, a first opposing
part 29a, a second opposing part 29b, a hole 30a in the first
protruding part, a hole 30b in the second protruding part, a hole
32a in the first opposing part, adjusting screws 40, securing
screws 50, and a wall mount 60.
[0040] As illustrated in FIG. 1 through FIG. 9, a wall mount 60
according to an embodiment of the invention can include a bracket
10, which may be secured to a fixed body, such as a wall surface,
etc., and a frame 20, which may be secured to the fixed body before
the bracket so as to allow levelness adjustments for the bracket
10. The frame 20 may support an outward portion of the bracket 10
and may locally push or pull the outward portion 12 of the bracket
10 to provide levelness adjustments for the bracket 10.
[0041] According to an embodiment of the invention, the bracket 10
can be secured to a fixed body, and an arm 70 can be rotatably and
movably coupled to the bracket 10, while a joining part 80 can be
coupled to a flat panel display device such as a PDP, LCD, etc., as
in the example illustrated in FIG. 2.
[0042] Thus, the levelness of a wall mount 60, as well as of a flat
panel display device secured to the wall mount 60, can be said to
depend on how accurately the bracket 10 is secured to the fixed
body, i.e. wall surface, etc.
[0043] According to an embodiment of the invention, the frame 20
can be positioned along the outer side of the bracket 10, so as to
surround the periphery of the bracket 10, and can thus support the
outward portion 12 of the bracket 10. The frame 20 can be shaped to
be open to one side.
[0044] The bracket 10 can be inserted into the frame 20 to be
coupled together. The bracket 10 can be slid into the frame 20 from
the open side of the frame 20. The frame 20 can include a guide
part 26, which may guide the bracket 10 as it is inserted into the
frame 20 and support the bracket 10 after it is inserted.
[0045] The guide part 26 can be shaped as a bent strip that extends
from an inward portion of the frame 20 touching the bracket 10 and
covers a portion of the outer side of the bracket 10.
[0046] According to an embodiment of the invention, the guide part
26 can include an upper guide part 26a, which may be formed on an
upper portion of the frame 20 to guide the bracket 10, and a lower
guide part 26b, which may be formed on a lower portion of the frame
20 to support the bracket 10. The guide part 26, which may secure
the bracket 10, may also be formed on the other side 24 of the
frame 20, opposite the one side 22, i.e. the open side, of the
frame 20.
[0047] A description will be provided as follows on the procedures
for installing a wall mount 60, and adjusting the levelness of the
wall mount 60, according to an embodiment of the invention.
[0048] According to this embodiment, the frame 20 may first be
secured to a fixed body, e.g. a wall surface, etc., as illustrated
in FIG. 3. The frame 20 does not have to be perfectly level.
[0049] Then, as shown in FIG. 4, the bracket 10, to which the arm
70 and the joining part 80 have been coupled, may be slid into the
frame 20. The upper guide part 26a and the lower guide part 26b may
guide the bracket 10, allowing a sliding motion. That is, in order
that the bracket 10 may be inserted in a sliding motion into the
frame 20 and coupled to the frame 20 after it is inserted, the
upper guide part 26a and lower guide part 26b can be shaped as
strips bent in correspondence to the thickness of the bracket
10.
[0050] Then, as illustrated in FIG. 5, adjusting screws 40 can be
inserted through the upper guide part 26a and lower guide part 26b.
That is, holes 27a, 27b may be formed in the upper and lower guide
parts 26a, 26b, through which the adjusting screws 40 may pass.
[0051] FIG. 6 is a magnified view of portion A in FIG. 5, while
FIG. 7 is a magnified view of portion B in FIG. 5.
[0052] The adjusting screws 40 penetrating the upper guide part 26a
and lower guide part 26b may each be placed in contact with the
outer side of the bracket 10. Internal threads can be formed in the
holes 27a, 27b of the upper guide part 26a and lower guide part
26b, through which the adjusting screws 40 may be inserted, in
correspondence to the threads formed on the adjusting screws 40. In
other words, a female thread may be formed in each of the holes
27a, 27b of the upper guide part 26a and lower guide part 26b that
correspond with the male thread formed in an adjusting screw
40.
[0053] As shown in FIG. 6, the thread of an adjusting screw 40 can
mate with the internal thread formed in the hole 27a of the upper
guide part 26a, with the end of the screw 40 penetrating the upper
guide part 26a to contact the outward portion 12 of the bracket 10.
According to this embodiment, an upper support part 18a can be
formed on an upper outward portion 14 of the bracket 10 with which
the adjusting screw 40 can be placed in contact. The upper support
part 18a can be shaped as a strip protruding from the upper outward
portion 14 of the bracket 10. Thus, when the adjusting screw 40
penetrating the upper guide part 26a is rotated, the adjusting
screw 40 may push on the upper support part 18a of the bracket
10.
[0054] Similarly, a lower support part 18b can be formed as a
protruding strip on a lower outward portion 16 of the bracket 10.
As shown in FIG. 7, a hole 27b can be formed in the lower guide
part 26b. An adjusting screw 40 may be inserted through the hole
27b in the lower guide part 26b to be in contact with the lower
support part 18b formed on the bracket 10. Thus, when the adjusting
screw 40 penetrating the lower guide part 26b is rotated, the
adjusting screw 40 may push on the lower support part 18b formed on
the bracket 10.
[0055] Thus, the bracket 10 surrounded and supported by the frame
20 can have the upper support part 18a and lower support part 18b
pressed on by the adjusting screws 40 penetrating the upper guide
part 26a and lower guide part 26b, respectively. In this particular
embodiment, an adjusting screw 40 can penetrate the upper guide
part 26a at a left side of the upper guide part 26a, while an
adjusting screw 40 can penetrate the lower guide part 26b at a
right side of the lower guide part 26b.
[0056] That is, the hole 27a in the upper guide part 26a and the
hole 27b in the lower guide part 26b can be formed in a diagonal
configuration, in order to enable the bracket 10 to rotate. Two
adjusting screws 40 can be arranged to penetrate opposite
directions in the guide part 26, and the upper support part 18a and
lower support part 18b of the bracket 10 may be formed
accordingly.
[0057] As in the example illustrated in FIG. 8, according to this
embodiment, the adjusting screw 40 penetrating the upper guide part
26a and the adjusting screw 40 penetrating the lower guide part 26b
can each be rotated and be made to press on the upper support part
18a and lower support part 18b of the bracket 10, respectively. The
upper support part 18a and the lower support part 18b can be pushed
by the adjusting screws 40, whereby the levelness of the bracket 10
may be adjusted.
[0058] In this particular embodiment, the center of mass of the
collective set of the bracket 10, arm 70, and joining part 80
inserted into the frame 20 may be located on the right side. If
there is no levelness adjustment, by way of the adjusting screws
40, after the bracket 10 is inserted into the frame 20, the bracket
10 may slant to the right. As such, by rotating the adjusting screw
40 that penetrates the left side of the upper guide part 26a and
the adjusting screw 40 that penetrates the right side of the lower
guide part 26b, the levelness of the bracket 10 can be adjusted, as
illustrated in FIG. 8. The more the adjusting screws 40 are made to
push on the upper support part 18a and lower support part 18b, the
more the bracket 10 may be tilted to the left.
[0059] The levelness of the bracket 10 and of the entire wall mount
60 can thus be adjusted according to the degree to which the
adjusting screws 40 push the upper support part 18a and lower
support part 18b. When the desired levelness is obtained, the
bracket can be secured, as a part of the configuration shown in
FIG. 8, to a fixed body, such as a wall surface, etc.
[0060] After the bracket is secured to the fixed body, the
adjusting screws 40 may be removed, as in the example shown in FIG.
9. In addition, the adjusting screws 40 may again be used to adjust
the levelness, if the wall mount 60 is tilted after a flat panel
display is coupled to the joining part 80 of the wall mount 60.
[0061] As such, according to the present embodiment, the burden of
having to secure the bracket 10 of a heavy wall mount 60 in the
exact position of the wall surface on the first try can be reduced.
By first securing the relatively light frame 20 to the fixed body,
and then adjusting the levelness after inserting the bracket 10,
the levelness of the wall mount 60 may be adjusted with little
effort to the exact degree of levelness desired.
[0062] A description will now be provided on a wall mount 60
according to another embodiment of the invention, with reference to
FIG. 10 through FIG. 16.
[0063] FIG. 10 is a perspective view of the frame of a wall mount
according to another embodiment of the invention. Referring to FIG.
10, the frame 20 may be open to one side and may be shaped to
support the outer side of the bracket 10, similar to configuration
in the previously described embodiment. The upper guide part 26a
and lower guide part 26b formed on the upper and lower portions of
the frame 20 may also serve to slidably couple the bracket 10, as
in the example described above.
[0064] According to this embodiment, the adjusting screws 40 used
for pushing or pulling the bracket 10 to adjust the levelness of
the bracket 10 can be arranged at the other side 24 of the frame
20. The adjusting screws 40 can be coupled to the other side 24 of
the frame 20, which faces the one side 22, i.e. the open side, of
the frame 20. Thus, the outward portion 12 of the bracket 10, which
may contact the other side 24 of the frame 10, may be pushed or
pulled by the adjusting screws 40, as in the example shown in FIG.
13.
[0065] On the other side 24 of the frame 20, a first protruding
part 28a can be formed, which an adjusting screw 40 may penetrate.
A hole 30a can be formed in the first protruding part 28a through
which the adjusting screw 40 may pass. A second protruding part 28b
can also be formed on the other side 24 of the frame 20, with a
particular distance from the first protruding part 28a.
[0066] The second protruding part 28b may also be penetrated by an
adjusting screw 40, and a hole 30b may be formed in the second
protruding part through which the adjusting screw 40 may penetrate.
An internal thread can be formed in the hole 30b of the second
protruding part 28b that corresponds with the thread of the
adjusting screw 40 penetrating the second protruding part 28b. That
is, a female thread may be formed in the hole 30b of the second
protruding part 28b that corresponds with the male thread formed in
the adjusting screw 40.
[0067] FIG. 11 is a perspective view of the bracket of a wall mount
according to another embodiment of the invention. Referring to FIG.
11, a first opposing part 29a and a second opposing part 29b can be
formed on the outward portion 12 of the bracket 10, in positions
corresponding to the first protruding part 28a and the second
protruding part 28b of the frame 20, respectively.
[0068] The first opposing part 29a and the second opposing part 29b
can be formed on the outward portion 12 of the bracket 10, which
comes into contact with the other side 24 of the frame 20. When the
bracket 10 is inserted in the frame 20, the first opposing part 29a
and the second opposing part 29b may each face the first protruding
part 28a and the second protruding part 28b, respectively.
[0069] In this embodiment of the invention, the first opposing part
29a may be pulled by the adjusting screw 40 penetrating the first
protruding part 28a, while the second opposing part 29b may be
pushed by the adjusting screw 40 penetrating the second protruding
part 28b.
[0070] According to this embodiment, a hole 32a can be formed in
the first opposing part 29a, with an internal thread formed in the
hole 32a in correspondence with the thread formed on the adjusting
screw 40 that penetrates the first protruding part 28a. That is, a
female thread may be formed in the hole 32a of the first opposing
part 29a that corresponds with the male thread formed in the
adjusting screw 40.
[0071] As in the example shown in FIG. 12, the bracket 10 can be
inserted into the frame 20, which may be secured to a fixed body
such as a wall surface, etc. As described above for the previously
disclosed embodiment, the wall mount 60 may be slanted to the right
before a levelness adjustment is applied using the adjusting screws
40.
[0072] Then, as illustrated in FIG. 13, adjusting screws 40 can be
coupled to the first protruding part 28a and second protruding part
28b, respectively, to gradually tilt the bracket 10 to the
left.
[0073] FIG. 14 and FIG. 15 are magnified views of portions C and D
in FIG. 13. As shown in FIG. 13 through FIG. 15, the adjusting
screw 40 that penetrates the first protruding part 28a may mate
with the internal thread formed in the hole 32a of the first
opposing part 29a, to be coupled with the first opposing part 29a.
Conversely, the adjusting screw 40 that penetrates the second
protruding part 28b may mate with the internal thread formed in the
hole 30b of the second protruding part 28b, to be in contact with
the second opposing part 29b.
[0074] Thus, by rotating each of the adjusting screws 40 that
penetrate the first protruding part 28a and second protruding part
28b, respectively, the first opposing part 29a can be pulled
towards the first protruding part 28a, while the second opposing
part 29b can be pushed away from the second protruding part
28b.
[0075] With the wall mount 60 having its center of mass positioned
on the right side and therefore slanted to the right, the adjusting
screws 40 may each be rotated, as described above, to adjust the
levelness of the bracket 10. That is, as in the example shown in
FIG. 13, the first opposing part 29a located on the outward portion
12 of the bracket 10 can be pulled, and the second opposing part
29b also located on the outward portion 12 of the bracket 10 can be
pushed away, to tilt the bracket 10 to the left.
[0076] Thus, according to this embodiment, the bracket 10 can be
secured to the fixed body by way of securing screws 50, as
illustrated in FIG. 16, with a degree of levelness desired by the
user.
[0077] Using certain embodiments of the invention, the burden of
having to secure the bracket of a heavy wall mount in the exact
position of the wall surface on the first try can be reduced. The
adjusting screws can be utilized to enable levelness adjustment, so
that the wall mount can be installed in a more convenient manner.
Because of such convenience in installation, the wall mount may be
secured to affixed body, e.g. wall surface, etc., by just one
person.
[0078] While the spirit of the invention has been described in
detail with reference to particular embodiments, the embodiments
are for illustrative purposes only and do not limit the invention.
It is to be appreciated that those skilled in the art can change or
modify the embodiments without departing from the scope and spirit
of the invention. As such, many embodiments other than those set
forth above can be found in the appended claims.
