Mount System Adapted to Rotate and Extend a Monitor
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.
1. Field of the Invention
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.
2. Background of the Invention
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.
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 SUMMARYThis 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.
Other systems, methods, features, and advantages of the 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 description, be within the scope of the invention, and be protected by the following claims.
The invention can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like referenced numerals designate corresponding parts throughout the different views.
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.
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.
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.
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
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.
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.
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.
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.
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,
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.
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.
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.
