US 2004/0000100 A1 · Steel wheel and steel rail system for a moveable wall panel system

Abstract

A track and trolley system for a movable wall system including a plurality of wall panels, including a track mounted to a ceiling with the track including a pair of rails, and a trolley operatively engaging said track. The wall panels are disposed in an open space and are capable of being moved into one of a variety of positions to separate the open space into smaller spaces. The trolley includes at least four wheels and an elongate member projecting downwardly between the wheels and coupled to one of the wall panels; each wheel includes a circumferential groove having an arcuate cross-section sufficiently larger than the rails to define a lubrication zone between the rails and the wheels. The wheels and rails comprise a metallic material such as steel, for increased strain tolerances.
