<p>A video display positioning and support system that permits the orientation of a video display towards the user with variations in vertical height, horizontal rotation, and angular tilt. The system includes actuators for each of the movements involved that are capable of control by way of a remote operating system. The system provides a platform upon which the video display may be placed. The platform may be tilted at an angle from the horizontal as controlled by an actuator positioned near the back of the platform. The platform may be rotated in a horizontal plane so as to direct the video display from side to side, by means of an actuator that turns the platform on a circular bearing track. The display platform is positioned on a support frame that is attached to a vertical lift actuator that raises and lowers the entire display. The lift actuator is attached to and supported by a base frame that holds a storage cabinet and has a number of wheels for easy movement of the complete system. The base frame, including the cabinet, have features that permit variations in the overall width of the frame so as to accommodate display devices of varying size. Finally, there are a number of safety features that prevent movement of the display device outside a specific range and distance or angle as well as devices that prevent movement when objects are inappropriately positioned nearby.</p> |
