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.

Insulated doors with restorable breakaway sections

A door includes a panel assembly including a leading panel and a trailing panel. The leading panel is to be in substantially coplanar alignment with the trailing panel when the panel assembly is in a normal configuration. The leading panel is to be angularly displaced out of coplanar alignment with the trailing panel when the panel assembly is in a dislodged configuration. The door further includes a tension member to connect the leading panel to the trailing panel. The tension member is to resiliently urge the leading panel and the trailing panel toward each other in a horizontal direction. The tension member is to resiliently urge the panel assembly toward the normal configuration when the panel assembly is in the dislodged configuration.

Example methods and systems to indicate the status of door operations are disclosed. An example door system includes a door panel having a leading edge to be moved in a travel direction between an open position and a closed position relative to the doorframe. The door panel to block the passageway when the leading edge is at the closed position. The door panel to unblock the passageway when the leading edge is at the open position. The example door system also includes a series of lights distributed along the travel direction proximate the doorframe. The example door system further includes a controller to switch the lights between a first state and a second state to provide a visual effect of movement corresponding to the operating status of the door system.
