Abstract
A track and trolley system for an operable wall panel which provides for linear motion. The track is mountable to a ceiling of a room and includes first and second surfaces. The trolley is attachable to the operable wall panel and includes first and second rotatable wheels that respectively engage the first and second track surfaces. The outer radial peripheries of the rotatable wheels and the engaged track surfaces are complementarily structured and arranged to limit movement of the first and second rotatable wheels relative to the surfaces of the track in the direction in which the axis of rotation of the track extends, while allowing the wheels to rotate about their axes of rotation and roll along the track surfaces.
