Abstract
A movable wall system for athletic courts makes the same court suitable for both racquetball, handball and squash play. The system disclosed includes a movable wall assembly between the front wall and back support structure at the back. Extensible and retractable side linkage assemblies connect between the movable wall assembly and back support structure that will stabilize the wall during movement. Side rollers and bottom rollers on the wall assembly facilitate sliding movement. Slide bolt catches hold the wall against movement in either the retracted or extended positions and latching mechanisms hold the wall assembly to the back wall in the retracted position.
