ABSTRACT:
A track system for slidably mounting a frame. The track system includes an upper track parallel to a lower track, and the tracks may be mounted to a wall. A left carriage upright and a right carriage upright are aligned orthogonally to the tracks, and the carriage uprights are slidably connected to the tracks on each end through a roller assembly, each roller assembly having a wheel that is slidably mounted to the corresponding track. The wheel is kept on the track by a stop at either end of the track. A stabilizing support structure fixes the left carriage upright parallel to the right carriage upright. Finally, the carriage uprights each have a bracket at each end, the brackets adapted to hold a frame and projector screen in front of the carriage uprights. The projector screen, frame, carriage uprights, and stabilizing support structure may then slide laterally as a whole.
