摘要:
A door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.
