Mount System Adapted to Rotate and Extend a Monitor
Abstract
A mount system rotates a monitor between a retracted position
and an extended position, and as the mount system rotates from the
retracted position to the extended position, the mount system moves
the monitor laterally along its longitudinal axis so that the
rotating side of the monitor is moved away from the monitor. This
allows the monitor to be installed recessed into the wall and swing
the monitor open 90 degrees; or tilt the monitor down while lifting
the monitor.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention is directed to a mount system that is adapted
to couple to a back side of a monitor and swing the monitor near
one its side.
[0003] 2. Background of the Invention
[0004] Flat panel monitors such as computer monitors, LCD, plasma,
slim televisions, and the like (collectively referred to as
"monitor(s)") are becoming popular because they can be mounted onto
a wall to save floor space and for their aesthetically pleasing
appearance. In many applications, the monitor is placed on a table,
mounted to a wall, or even hung from a ceiling. In these
applications, however, in order to reposition the monitor, the
viewer needs to walk over to the monitor and physically move the
monitor to a new viewing angle.
[0005] Motorized swinging mounts are now available that are
designed to swing the monitor open much like a door that swings
from one of its sides. These motorized swing mounts are provided
with a pivot point that swings opens and closes through motorized
action. The motorized swing mounts are designed so that their pivot
points are design to be juxtaposed on the side outer edge of the
monitor so that the monitor can swing open 90 degrees. Such
motorized swing mounts, however, have a number of limitations.
First, with the pivot point on the back side and located on the
side outer edge of the monitor, much of the motorized swing arm is
exposed so that it is esthetically unpleasing. Second, in many
applications, it may be desirable to install the motorized mount or
the combination of the monitor and the motorized mount to be
recessed into the wall. Such recessed installation, however,
minimizes the gap between monitor and the wall so that the
motorized swing arm is prevented from swinging the monitor to the
fully open position or 90 degrees. Accordingly, there is a need to
be able to swing open a monitor so that the motorized mount is not
exposed on the side of the monitor and mounted recessed into the
wall.
INVENTION SUMMARY
[0006] This invention is directed to a mount system adapted to
rotate a monitor between a retracted position and an extended
position, and as the mount system rotates from the retracted
position to the extended position, the mount system moves the
monitor laterally along its longitudinal axis so that the rotating
side of the monitor is moved away from the monitor. This allows the
monitor to be installed recessed into the wall and swing the
monitor open 90 degrees; or tilt the monitor down while lifting the
monitor.

invention will be, or will become, apparent to one with skill in
the art upon examination of the following figures and detailed
description. It is intended that all such additional systems,
methods, features, and advantages be included within this

DETAILED DESCRIPTION OF THE INVENTION
[0025] FIG. 1 shows a perspective view of a mount system 10 having
a chamber 12 between a wall bracket 14 and a monitor mounting
bracket 16. The wall bracket 14 may include a middle bracket 22
between first and second elongated plates 24 and 26. The chamber 12
may be supported by first and second anchors 27 and 29, and adapted
to rotate along the longitudinal axis 20 of the chamber 12. The
first and second anchors 27 and 29 may be coupled to the first and
second elongated plates 24 and 27, respectively. The first and
second elongated plates 24 and 26 may have elongated openings 28
adapted to receive screws to attach the wall bracket to the wooden
studs within the wall or the other types of wall such as
concrete.
[0026] The monitor mounting bracket 16 may include first and second
rail bars 30 and 32. The first rail bar 30 includes a first inner
rail 34 and a first outer rail 36 where the first outer rail 36 may
be adapted to slide relative to the first inner rail 34. For
instance, rollers or ball bearings may be provided between the
outer and inner rails to allow the outer rail to slide smoothly
relative to the inner rail. The second rail bar 32 may have similar
second inner and second outer rails 38 and 40 as the first rail bar
32. The proximal end 68 of the first inner 34 rail may be coupled
to a first end 70 of the camber 12, and the proximal end 72 of the
second inner rail 38 may be coupled the second end 74 of the
chamber 12.
[0027] A motor 18 may be mechanically coupled to the chamber 12
adapted to rotate the chamber 12 along its longitudinal axis 20.
The motor 18 may be coupled to the second anchor 29. It is within
the scope of this invention to provide the motor 18 in a variety of
other locations such as within the chamber 12. As the motor is
activated based on a control signal, the chamber 12 may rotate,
which in turn rotates the monitor mounting bracket 16.
[0028] A first linking bar 42 may be provided between the first and
second inner rails 34 and 38. A first roller 44 may be provided
with the first linking bar 42 to allow the first roller 44 to
rotate along the longitudinal axis of the first linking bar 42. A
second linking bar 46 may be provided between the chamber 12 and
the first linking bar 42. A sleeve 48 may be provided with the
second linking bar 46, where the sleeve 48 may be adapted to move
along the longitudinal axis of the second linking bar 46. A third
linking bar 47 may couple the two outer rails 36 and 40 together so
that the two outer rails 36 and 40 slide simultaneously along their
respective inner rails 34 and 38.
[0029] A beam 50 may be provided between the middle bracket 22 and
the sleeve 48. The proximal end 52 of the beam 50 may be pivotably
coupled to the middle bracket 22 and the distal end 54 of the beam
50 may be pivotably coupled to the sleeve 48 so that the distal end
54 may slide along the longitudinal axis of the second linking bar
46. As the monitor mounting bracket 16 extends relative to the wall
bracket 14, the sleeve and the proximal end 54 move closer to the
chamber 12. Conversely, as the monitor mounting bracket 16 retracts
relative to the wall bracket 14, the sleeve and the proximal end 54
move closer to the first linking bar 42 such that the bracket 16,
beam 50, and wall bracket 14 folds juxtaposed to the wall, as shown
in FIG. 2.
[0030] A second roller 56 (not shown) may be provided within the
chamber 12 adapted to freely rotate therein. The chamber 12 may
have two holes 64 and 65 adapted to receive a cable 58 to wrap
around the second roller 56 within the chamber 12 and the first
roller 44. The cable 58 may have a first side 60 and a second side
62 divided by the two rollers 44 and 56 so that the first side 60
of the cable 58 rotates in the opposite direction as the second
side 62 of the same cable 58. The first side 60 of the cable 58 may
be coupled to the sleeve 48 so that as the sleeve 48 slides along
the longitudinal axis of the second linking bar 46, the cable 58
rotates around the two rollers 44 and 56, accordingly. The second
side 62 of the cable 58 may be coupled to the third linking bar 47
so that the two outer rails 36 and 40 slide along their respective
inner rails 34 and 38 in the same direction as the second side 62.
As such, as the monitor mounting bracket 16 extends relative to the
wall bracket 14, the two outer rails 36 and 40 slides away from the
chamber 12 along the longitudinal axis of the first and second rail
bars 30 and 32, and vice versa.
[0031] FIG. 2 shows a top view of the mount system 10 and a monitor
200 recessed into a wall 202 in a retracted position. Brackets 204
may be used to attach the back side of the monitor 200 to the first
and second outer rails 36 and 40 so that the monitor 200 may slide
with the two outer rails 36 and 40. In the retracted position, the
sleeve 48 is closer to the first roller 44 in comparison to the
location of the sleeve 48 shown in FIG. 1, which is in an extended
position. Conversely, the third linking bar 47 and the outer rails
36 and 40 are closer to the chamber 12.
[0032] FIG. 3 shows a top view of the mount system 10 and the
monitor 200 in a partially extended position in comparison to FIG.
2. In this position, the sleeve 48 is closer to the chamber 12, and
the third linking bar 47 and the outer rails 36 and 40 are closer
to the first roller 44 than in FIG. 2. With the monitor 200 coupled
to the outer rails 36 and 40, as the monitor rotates or swings open
along the direction arrow 300, the monitor also extends out along
the direction arrow 302, which is in line with the longitudinal
axis of the outer rails 36 and 40. As such, the right side 304 of
the monitor 200, when facing the monitor, moves away from the right
side of the wall 306 to allow the monitor to swing open along its
right side without the interference from the right side 306 of the
wall 202.
[0033] FIG. 4 shows a top view of the mount system 10 in an
extended position where the monitor 200 is substantially
perpendicular to the wall 202. In this position, the sleeve 48 is
closer to the chamber 12, and the third linking bar 47 and the
outer rails 36 and 40 are closer to the first roller 44 than in
FIG. 3. Note that in this fully extended position, the third
linking bar 47 may be aligned with the first linking bar 42. With
the mechanical relationship between the rotation of the chamber 12
and the movement of the outer rails 36 and 40, the rotational or
swing movement 300 and the extension movement 302 are synchronized
so that the monitor 200 may be moved within its recess wall without
being impeded by the wall 202.
[0034] FIG. 5 shows a cross-sectional view of the chamber 12 along
the line 5-5 shown in FIG. 4. A shaft 500 of the motor 18 may be
mechanically coupled to the chamber 12 through one or more gear
mechanisms 502 to transfer the rotational speed and torque of the
motor 18 to the chamber to rotate the chamber at a desired
rotational speed about the longitudinal axis 20. In particular, the
gear mechanisms 502 between the motor 18 and the chamber 12 may
have a slippage torque mechanism 504 to slip when the chamber 12 is
in a lock condition such that it can not rotate while the motor is
powered. This substantially prevents the motor from burning out and
stops the monitor 12 from rotating when a foreign object interferes
with the movement of the monitor. The slippage torque mechanism may
be provided within the second anchor 29.
[0035] The slippage torque mechanism 504 includes a cup 506 that
may be coupled to the second end 74 of the chamber 12 through one
or more screws 508. The cup 506 may house one or more spring rings
510 that resist compression. The shaft 500 of the motor 18 may have
a first worm gear 512 that engages with a second worm gear 514. The
second worm gear 514 may have a protruding portion 516 with a
threaded end 518. The cup 506 and the spring rings 51 0 may each
have an opening to receive the protruding portion 516. The spring
rings 510 and the base 520 of the cup 506 may be between first and
second washers 522 and 524. A bolt 526 may be used to tighten along
the threaded end 518 to compress the spring rings 510 so that a
predetermined amount of torque resistance between the chamber 12
and the slippage torque mechanism 504 may be applied. This allows
the slippage torque mechanism 504 to rotate or the motor 18 to
rotate the second worm gear 514 while the chamber 12 is held or
does not move.
[0036] The first end 70 of the chamber 12 may be coupled to the
first anchor 27 with a bolt 530. The first anchor 27 may have an
opening 532 along its base 534, where the diameter of the opening
532 is greater than the diameter of the bolt 530. The bolt 532 may
pass through the opening 532 and tightened to allow the chamber 12
to rotate about its longitudinal axis. The opening 532 is large
enough so that the orientation of the longitudinal axis may be
adjusted so that the monitor attached to the first and second rail
bars 30 and 32 may be leveled.
[0037] The second roller 56 may be provided within the chamber 12
and supported by a brace 534. The cable 58 may wrap around the
second roller 56 to rotate the cable 58 around to move the monitor
along the longitudinal axis of the first and second rail bars 30
and 32, as discussed above. In addition, a control circuit 536 may
be housed within the chamber 12. The control circuit 536 may have
an input port 538 adapted to couple to a receiver adapted to
receive control signals from a remote control to move the monitor.
Another input port 540 may be provided to receive power for the
motor 18.
[0038] FIG. 6 shows an enlarged view of the blocked area 6 of FIG.
3. A coupler 600 may be used to attach the third linking bar 47 to
the cable 58. The coupler 600 may be released to adjust the
position of the outer rails 36 and 40 relative to the inner rails
34 and 38 and retightened. The second side 62 of the cable 58 may
be located between the two outer rails 36 and 40 to minimize the
depth space "d" of the mount system 10. The sleeve 48 may have a
protruding portion 602 adapted to pivotably couple to the distal
end 54 of the beam 50. The two ends 604 and 606 of the cable 58 may
be coupled to the protruding portion 602 of the sleeve 48 so that
the cable 58 rotates around the first and second roller 44 and 56
as the sleeve 48 moves along the longitudinal axis of the second
linking bar 46.
[0039] FIG. 7 shows a cross-sectional view of along the line 7-7 of
FIG. 6. The third linking bar 47 may couple the first and second
outer rails 36 and 40 together. The first linking bar 42 may couple
the two inner rails 34 and 38 together. A number of ball bearings
700 may be provided between the inner and outer rail bars 34 and
36, and 38 and 40 to allow the outer rails 36 and 40 to slide
smoothly relative to their respective inner rails 34 and 38. The
first roller 44 may have an hourglass shape to retain the cable
58.
[0040] While various embodiments of the invention have been
described, it will be apparent to those of ordinary skill in the
art that many more embodiments and implementations are possible
within the scope of this invention. For instance, FIG. 8 shows that
the motor 18 may be mechanically coupled to the proximal end 52 of
the beam 50 to rotate the distal end 52 along the hinge 800. As the
motor 18 rotates the proximal end 52, the monitor mounting bracket
extends and retracts relative to the wall bracket 14, and the outer
rails 36 and 40 extends and retract along its longitudinal
axis.
[0041] FIG. 9 shows that the second linking bar 46 may be treaded
and the proximal end 900 of the second linking bar 46 may be
coupled to a motor to rotate the second linking bar 46. The sleeve
48 may have a threaded opening adapted to receive the threaded bar
46. As the motor rotates the thread bar 46, the sleeve moves along
the longitudinal axis of the bar 46 to cause the monitor mounting
bracket to extend and retract relative to the wall bracket 14, and
the outer rails 36 and 40 to extend and retract along its
longitudinal axis.
[0042] FIG. 10 shows a mount system 1000 that may extend the
monitor 200 in a substantially perpendicular manner as indicated by
the direction arrows 1002-1008. As the first motor 18 rotates the
monitor mounting bracket 16, a second motor 1010 within the chamber
12 may rotate a screw 1012, which in turn moves the sleeve 1014
along the longitudinal axis of the screw 1012. As the sleeve 1014
moves, the outer rails 36 and 40 slides along the inner rails 34
and 38 accordingly. The control circuit 536 may control the two
motors 18 and 1010 so that that the distal end 1016 extends
relative to the wall bracket 14 in a substantially perpendicular
manner. A third motor 1018 may be coupled to the distal end 1016 to
swivel the monitor 200 so that the monitor 200 extends in a
substantially parallel manner relative to the wall bracket 14. A
bracket 1020 may be provided between the monitor 200 and the third
motor 1018 to attach the monitor 200 to the mount system 1000.
[0043] FIG. 11 shows a perspective view of a mount system 1100
similar to the mount system 10 described above. The mount system
1100, however, has a bracket 1102 between a first anchor 1104 and a
second anchor 1106. The bracket 1102 may have an "L" shape
configuration. The second anchor 1106 may be adapted to
mechanically couple to a motor 18 to rotate the bracket 1102 about
a pivot axis 1108. The bracket 1102 may be coupled to the two inner
rails 34 and 38. The mount system 1100 may include a first limit
switch 1110 and a second limit switch 1112 located on the second
linking bar 46 to define the fully extended position and the fully
retracted position, respectively. As the sleeve 48 moves along the
second linking bar 48 and as it makes contact with the limit
switches 1110 and 1112, the control system of the mount system 1110
may stop the mount system 1100 from moving. The location of the
limit switches 1110 and 1112 may be adjusted along the second
linking bar 46 to adjust the fully extended position and the fully
retracted position, respectively. A coupler 1114 may couple the
second side 62 of the cable to the third linking bar 47, which
slides the first and second rail bars 30 and 32 along the inner
rails 34 and 38.
[0044] FIG. 12 shows that a first cover 1200 may be used to enclose
the bracket 1102, and a second cover 1202 may be used to enclose
the second linking bar 46. The first cover 1200 may have openings
1204 and 1206 to route the cables and wires. The second cover 1202
may have an elongated opening 1208 to allow the distal end 53 of
the beam to move along the second linking bar 46.
[0045] FIG. 13 shows a side view of a mount system 1300 similar to
the mount system 1100 described above. The mount system 1300,
however, has an inner bar 1302 that has a U-shape between first and
second outer bars 1304 and 1306. First and second set of rollers
1308 and 1310 may be provided between the inner bar 1302 and the
first and second outer bars 1304 and 1306 to slide the first and
second outer bars 1304 and 1306 along the inner bar 1302 as
described in more detail below. The first and second outer bars
1304 and 1306 and the first and second set of rollers 1308 and 1310
may be coupled to a cross plate 1312 so that they may slide in
unison along the inner bar 1302. A belt 1314 may be coupled to the
distal end 54 of the beam 50 and the cross plate 1312 to slide the
cross plate 1312 along the inner bar 1302. Panel mounting brackets
1316 may be provided to attach to the rear side of the monitor 200
and couple to the first and second outer bars 1304 and 1306.
[0046] FIG. 14 is a front cross-sectional view of the mount system
1300 along the line 14-14 of FIG. 14. The inner bar 1302 has a
proximate end 1318 and a distal end 1318 and a distal end 1320. The
inner bar 1302 may form a U-shape with the distal end 1320 being
the base. The proximate end 1318 may be coupled to the bracket
1102, as described above in reference to FIG. 11. The bracket 1102
may be adapted to rotate about the pivot axis 1108 to rotate the
proximate end 1318 as well. A first link bar 1322 may be provided
within the bracket 1102 and along the pivot axis 1108. The second
roller 56 may be adapted to rotate around the first link bar 1322.
The first roller 44 may be adapted to rotate around the distal end
1320 of the inner bar 1302. The belt 1314 may wrap around the first
and second rollers 22 and 56, and the belt may be coupled to the
cross plate 1312.
[0047] The cross-plate 1312 may be coupled to the first and second
set of rollers 1308 and 1310, and the first and second outer bars
1304 and 1306. The first set of rollers 1308 may include a
plurality of rollers 1324, 1326, and 1328; and the second set of
rollers may include a plurality of rollers 1330, 1332, and 1334.
The inner bar 1302 may pass between the two rollers (1324 and 1328)
and roller 1326 on one side; and on the opposite side, the inner
bar 1302 may pass between the two rollers (1330 and 1334) and
roller 1332. A second link bar 1336 may be provided between third
and fourth link bars 1338 and 1340. The sleeve 48 coupled to the
distal end 54 of the beam 50 may slide on the longitudinal axis of
the second link bar 1336. The belt 1314 may be coupled to the cross
plate so that as the belt 1314 rotates around the two wheels 44 and
56, the cross-plate moves along the inner bar 1302. The third link
bar 1338 may be provided near the distal end 1320 of the inner bar
1302 to stop the rollers 1326 and 1332 near the distal end 1320 so
that the first and second set of rollers 1308 and 1310 do not
disengage with the inner bar 1302 at it rotates about the pivot
axis 1108 to extend the mount system 1300 position.
[0048] FIGS. 15 and 16 illustrate that the mount system 10 may be
orientated in a variety of directions in reference to YZ
coordinates. For instance, FIGS. 15 and 16 show a side view of the
mount system 10 in a retracted position and an extended position,
respectively, to tilt the monitor 200. The weight of the monitor
200 may be represented as a center of gravity 1500 located about
its center. In this orientation, as the mount system 10 moves from
the retracted position to the extended position, the tilt angle
.theta.1 increase, which causes the center of gravity 1500 of the
monitor 200 to shift towards the positive Y and Z axes. As the
mount system 10 extends or tilts, the bottom rear corner 1502 of
the monitor 200 substantially maintains a gap with the wall 1504 so
that the wall does not interfere with the tilting of the monitor
200. Moreover, in the top portion of the monitor 200, a substantial
gap is formed between the monitor and the wall so that the rear
side of the monitor is readily accessible for servicing and
installing the cables and wires to the rear side of the
monitor.
[0049] In this example, the gravitational force "g" may be in the
-Y direction. With the center of gravity 1500 of the monitor 200
being offset in the +Y and +Z direction relative to the
longitudinal axis 20 of the chamber 12, the first and second rail
bars 30 and 32 have a tendency to extend or tilt down due to the
moment of inertia applied by the weight of the monitor being
offset. In order for the first and second rail bars 30 to extend or
tilt, the monitor needs to move in the +Y direction or be lifted
against the direction of the gravitational force "g". At the same
time, the weight of the monitor applies downward force on the first
and second rail bars 30 to resist against extending or tilting the
monitor. As such, the moment of inertia, due to the weight of the
monitor being offset, is substantially counter balanced by its own
weight of the monitor. Accordingly, the monitor 200 can be moved
between the retracted position and the extended position with a
nominal force applied to the monitor 200 or the first and second
rail bars 30. And, once the monitor has been moved, the monitor may
be maintained at that position with little or no resistive force.
In this example, the mount system 10 may or may not include a motor
so that the mount system 10 can be operated through a motorize
action or manually.
[0050] The motorize mount systems described above show the mounts
attached to the right side, when facing the monitor, of the
monitor. The mounts, however, may be rotated and attached to the
lefts side of the monitor as well, depending on the desired
movement by the viewer. While motorized mounts have been described,
non-motorized mounts or manual mounts are within the scope of this
invention. Moreover, a motorized lift system such as the mechanisms
found in the motorized car seats may be provided between the wall
bracket 16 and the wall 202 to lift and lower the motorized mount
system and the monitor. Accordingly, the invention is not to be
restricted except in light of the attached claims and their
equivalents.
