ABSTRACT:
A channel is formed between the inner and outer walls in each meeting edge of the doors in a double swinging door installation, and an elongated leaf is pivotably mounted in the channel of each door and extends substantially the full height of its door. Each leaf is pivotable in its channel between a first position adjacent the outer wall of its door where the leaf protrudes out of its channel toward engagement with the leaf of the other door, and a second position away from the outer wall of its door in which the leaf is substantially retracted into its channel. Coil torsion springs urge the leaf of each door toward its retracted position, and a door stop is located in the door frame at the meeting edge portions of the doors for urging the leaves of the doors toward their protruding and engaging positions when the doors are in their closed positions.
