ABSTRACT:
A threshold assembly for mounting on a door and a door sill is described which includes a threshold plate assembly formed of nonmagnetically attracted material and a door cap assembly for mounting on the bottom edge of the door. The threshold plate assembly has a first stepped portion with a substantially vertical face extending medially along the bottom edge of the door. This first stepped portion comprises: a riser portion and a stair portion extending from the lower edge of the riser portion inwardly toward and beyond the interior surface of a door. Second stepped portion on the bottom edge of a door includes the lowermost portion corresponding to stair portion of the first stepped portion and the uppermost portion corresponding to a saddle portion. A magnet mounting device for attachment to the lowermost portion of a second stepped portion includes: a slot extending substantially vertically adjacent the lowermost portion and a guard plate extending substantially horizontally adjacent the stair portion. A magnet holding assembly mounted to the magnet-mounting device that includes: a T-shaped mounting flange for mounting within a slot with the stem protruding therefrom; an extensible bellows attached at one end to the stem permitting the horizontally extending movement of the magnet assembly when magnetic attraction exists and horizontally retracting movement of the magnet assembly when magnet attraction ceases, and a pocket with one side attached at the other end of the extensible bellows.
