Abstract
A building structure having a roof opening which is covered by a retractable closure. The retractable closure includes a plurality of panels which are pivotally mounted about the margin of the roof opening. The panels are sized and shaped so that they fit together and cover the opening when in their closed positions, and when the panels are in their open positions the roof opening is completely unobstructed. Tracks on the roof support the panels and resist vertical load forces. Support towers and guy lines are provided to bear a part of the load forces as the panels are closed. Drive means is provided for opening and closing the panels conjointly or independently to achieve a range of roof opening capability.
