Abstract
An automatic tensioning side track assembly includes a stationary base track, a dynamic screen receiver, a first magnet, a second magnet, and a screen. The first magnet is oppositely charged relative to the second magnet and is configured to maintain an attractive magnetic force with the second magnet. The first magnet is disposed at a first position associated with a first rectilinear horizontal distance away from the second magnet when the screen is at a substantially planar configuration and has a desired tensioned state. The first magnet is disposed at a second position associated with a second rectilinear horizontal distance away from the second magnet when the screen is at a substantially bowed configuration and has an undesired tensioned state. The first magnet is configured to automatically return from the second position to the first position after the screen is displaced to the substantially bowed configuration.
