This invention is directed to a motorized mounting system capable of adjusting the viewing angle of a monitor based on an input signal from a remote control.
Flat panel monitors such as computer monitors, TFT, LCD, plasma, slim televisions, and the like (collectively referred to as “monitor(s)”) are becoming popular because they can be mounted against a wall to save floor space and for their aesthetically pleasing appearance. In general, monitors are mounted to a wall with a mechanical support arm or a bracket then fixed in a desired orientation to maximize the viewing angle of the monitor. To later adjust the viewing angle of the monitor, however, a viewer generally tilts the monitor manually to a new viewing angle so that the viewer may more comfortably view the monitor from a different location or to deflect a glare on the monitor away from the viewer. For instance, a monitor may be fixed to a wall in a family room to allow the family members or one viewer to view the monitor at the desired viewing angle. As the viewer moves from one area to another area, such as from the family room to the kitchen, the viewer may not be able to view the monitor. In addition, in situations where the monitor is mounted in a remote location or high above the floor, it may be inconvenient for the viewer to adjust the viewing angle of the monitor.
Another limitation with the support arm is that there is a limit as to how much weight the support arm can handle. That is, as the support arm is extended to support a monitor further away from the wall, the weight of the monitor applies bending load on the support arm. The bending load on the support arm increases as the distance between the monitor and the wall increases. Bending loads can apply extreme stress on the support arm. As such, with heavier monitors, support arms are not generally used. Rather, wall mounts are used to attach the heavier monitors to a wall with the viewing angle fixed at a predetermined orientation. The wall mounts do allow for some tilting of the monitor but do not allow the monitor to extend from the wall. Accordingly, there is a need for a mounting system that can mount a larger and heavier monitor to a wall and allow the viewing angle of the monitor to be more easily adjusted.
This invention is directed to a mounting system capable of adjusting the viewing angle of a flat panel monitor. The mounting system includes a plurality of motorized arms adapted to couple to the back side of a monitor. A processor controls the actuation of the plurality of motorized arms to extend or retract each of the motorized arms independently relative to a mounting surface such as wall. As an example, the mounting system may include three motorized arms that are coupled to the back side of the monitor in a triangular configuration. By independently varying the distance of the three arms with respect to the mounting surface, the angle of the plane defined by the three arms may be adjusted or the viewing angle of the monitor. The processor may be controlled by the input signal from a remote control so that the viewing angle of the monitor may be adjusted remotely.
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 mounting system 10 also includes motors 24, 26, and 28 where the motors 24 and 28 may be coupled to their respective screws 30 and 34 to rotate the screws about their longitudinal axes. The motor 26 may be coupled to a hinge 32 to rotate the hinge along its longitudinal axis. In this example, the motors 24 and 28 may be located along the longitudinal axes of their respective screws 30 and 34. In addition, the motors 24 and 28 may be located between their respective screws and universal pivot joints 36 and 38. The screws 30 and 34 may be supported by one or more support walls 42. The support walls 42 may be adapted to allow the screws 30 and 34 to rotate along its longitudinal axis or along the Y-axis
The first or proximal ends 12A and 20A of the beams 12 and 20, respectively, may be pivotably coupled to sleeves 40 and 44, respectively. The sleeves 40 and 44 may be threaded to receive the screws 30 and 34, respectively, so that the sleeves may move along the longitudinal axis of their respective screws as they rotate. Depending on the rotational direction of the screw, the sleeve may move substantially along the positive Y-axis or negative Y-axis. As the sleeves 40 and 44 move or slide along their respective screws 30 and 34, the respective second or distal ends 12B and 20B extend or retract relative to the first mounting surface 2. The second ends 12B and 20B may be pivotably coupled to the second mounting surface 4 at locations 9 and 11, respectively. The second ends 12B and 20B of the beams 12 and 20, respectively, may be adapted to pivotably couple to the second mounting surface 4 so that the viewing angle of the second mounting surface 4 may be adjusted by moving the sleeves 40 and 44 along their respective screws 30 and 34. As such, movement of the sleeves along the XY-plane allows the second ends 12B and 20B to independently or simultaneously extend or retract relative to the XY-plane to adjust the viewing angle of the second mounting surface 4. The second end 16B of the beam 16 may be pivotably coupled to mounting surface 4 at a location 13. Note that locations 9, 11, and 13 may be located at the back side of the monitor forming a triangular configuration with the location 13 between the locations 9 and 11.
The mounting system 10 also includes a remote control 15 adapted to communicate with a processor 17 to adjust the viewing angle of the second mounting surface 4 such as a monitor. The remote control 15 may send wireless signals to a receiver 19 which is communicably coupled to the processor 17. The processor may be also communicably coupled to a memory 21 that stores predetermined desired viewing angles so that a viewer may push a preset button on the remote 15 to adjust the viewing angle of the monitor to the desired viewing angle previously stored in the memory. The remote control 15 includes a tilt up button 23, tilt down button 25, swivel left button 27, swivel right button 29, extend button 31, and a retract button 33. As explained in more detail below, a viewer may push any of the above buttons to adjust the viewing angle of the monitor to a desired viewing angle.
With the second end 20B moving substantially along the XZ plane, the motor 28 substantially extends or retracts the second end 20B to push or pull the monitor 4 relative to the first mounting surface 2 such that the monitor 4 does not move along the Y-axis by the arm 7. For example, if the gravitational force is along the negative Y-axis, the arm 7 does not lift the monitor. Without the need to lift the monitor, such as a 42 inch plasma TV weighing about 70 pounds, smaller size motors may be used to adjust the viewing angle of the monitor. With a smaller size motor, the motor 28 may be located between the hinge 52 and the screw 34, along with a gear box 62 and a coupler 64. The coupler 63 mounts the gear box 62 to the screw 34 so that torque from the motor 28 may be transferred to the screw 34 for rotation. As the motor 28 rotates the screw 34, the sleeve 44 may move along the longitudinal axis of the screw to extend or retract the second end 20B of the beam 20.
