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.
Claims18
For use with a door hinged in a doorway, a threshhold assembly comprising
- an elongated subpan adapted to be mounted in said doorway and to extend across the doorway, said subpan including means for effecting drainage therefrom, an elongated threshhold member mounted to said subpan and positioned above a forward portion thereof, an elongated upper pan mounted to said subpan and spaced above said subpan, said upper pan extending along the length of said subpan and across the width of said subpan from a rear edge thereof to a rear edge of said threshhold member,
- said upper pan having a width substantially equal to the thickness of said door,
- drainage means interconnecting said subpan and upper pan,
- a door jamb upstanding at a side of said doorway,
- a first flexible elongated sealing strip fixed to and extending along said jamb,
- a second flexible elongated sealing strip fixed to and extending along the rear edge of said threshhold member,
- said second sealing strip having an elongated upstanding fin that overlaps said first sealing strip at adjacent ends of said strips, one of said sealing strips adapted to be engaged by said door to thereby be pressed against the other of said sealing strips at said jamb and provide a tightly sealed corner at the bottom of said jamb.
