Abstract
The coordinator has a pair of spaced-apart limbs pivotably mounted to a housing; one of the limbs functions to hold a door open, whereas the other limb is disclosed for impingement by another door and, as a consequence thereof, causes activation of the door coordinator, i.e., triggers a proper, sequential closing of the two doors, in which the inactive door proceeds to close, while the active door is held open. A carriage slidably mounted to the housing has a lobe which intrudes into the pivotable arc of one of the limbs to prevent that limb from allowing its door to close before the door, held open by the other limb, has closed. A blocking arm keeps the carriage in its lobe-intrusive position, and has a linkage with the other limb. Accordingly, as the other limb permits the closure of its door, the linkage moves the blocking arm to allow the second door to close. If an unusually excessive force is applied to the second door, toward its closure before the other, a rod supported by the carriage moves against the blocking arm, displaces it, and allows the second door to close.
