Title: Door seal assembly

Abstract: A door assembly having first and second pivotally mounted doors defining juxtaposed portions in a closed arrangement thereof. A seal structure is provided for sealing the juxtaposed edges of the doors in the closed arrangement. The seal structure defines inner and outer seals cooperatively forming a large closed air space therebetween. The seals may include overlapping sealing portions which may have magnetized structures therein for effecting a positive seal. The seals may include relatively stiff or rigid mounting portions secured to rearwardly projecting dikes on the doors and effectively defining opposed projections of the dikes extending a substantial portion of the distance between the dikes. The seals may include flexible sealing portions at the distal ends of the rigid mounting portions.
