ABSTRACT:
An inwardly swinging door is provided with a threshhold assembly that effectively seals against entry of driven water and air. The threshhold assembly includes a sloping subpan having an upstanding rear wall. An integral outer threshhold member and upper pan are connected to and above the subpan. The upper pan provides a primary seal at the front edge of the door bottom and defines a primary sill floor that cooperates with the flexible wiper blades carried by the door bottom to define secondary barriers. The inner side of the door bottom carries a final seal which bars entry of air that may be driven through drainage holes provided in the subpan and interconnecting the interior of the subpan with the interior of the upper pan.
