Abstract
A door seal for use with a bi-parting door in which the door panels of the door have supplementary angled leading edges. One leading edge has a triangular cross-section, while the other has a cross-section similar to a parallelogram. To further the reliability of the door seal, a plurality of magnets with corresponding magnet attracting plates may be attached along the leading edges. Alternatively, both leading edges may have at least one magnet aligned with a magnet on the other edge. With the double magnet configuration, the use of multi-pole magnets is necessary. The magnets also help reduce the bounce between the door panels, which may be closed roughly, and increase the force required to separate the door panels when closed.
