ABSTRACT:
A dryer door mechanism for the opening, closing and sealing of an opening to a dryer enclosure. The door mechanism has a movable door in rolling engagement with a pair of tracks affixed to a door frame. The tracks of the door frame are angularly disposed from both the plane of the enclosure opening and the plane of the movable door. The movable door, while rolling along its track, simultaneously moves perpendicular and parallel to the plane of the enclosure opening. When moved to the closed position, the movable door becomes wedged against the enclosure opening thereby providing a force perpendicular to the opening of the enclosure for creating an airtight seal.
