Patent

CA 2373729

A track and trolley system that allows wall panels to be moved with a minimum amount of friction is disclosed. The track has first and second flanges vertically and horizontally spaced relative to each other. First and second discs are supported on a shaft in vertical spaced relation. One of the discs engages one of the flanges on one side of the shaft and the other disc engages the other flange on the other side of the shaft. Each disc is independently rotatable in opposite directions. The disc-supporting surface of the flanges includes a plurality of upwardly concave regions with each region formed with a different radius. The disc is sized so that the outer edge of the disc lower surface contacts the outermost upwardly concave region of the flange. The lower side of the discs is angled slightly upward from the outer edge toward the center. The combination of the contours of the disc lower surface and the disc-supporting flange surfaces result in a narrow contact area between the discs and flanges which minimizes friction between the discs and their respective flange as the wall panels are moved.
