Abstract

An improved door bottom and sill assembly for inswing exterior doors is disclosed. The door bottom and sill assembly consists of a bottom portion and a sill portion. The bottom portion has a sealing member along the interior bottom edge of the door. The sill portion mates with the sealing member when the door is in a closed position, forming a tight weather barrier.

Claims

1. An improved bottom and sill assembly for mounting on exterior doors comprising;

a bottom assembly for mounting on such door, said bottom assembly having a flexible and generally tubular sealing member extending along the inner edge of such door and projecting downwardly, said sealing member having a flexible and deflectable exterior wall spaced from an inside wall, a sill assembly positioned below and in mating relationship with said bottom assembly when such door is in a closed position, said sill assembly defining a horizontally extending projection adjacent the inner edge of such door which engages and deflects said sealing member when said door is closed to provide a weather-impervious barrier, said sealing member extending downwardly to an elevation below said horizontally extending projection, said horizontally extending projection deflecting said flexible and deflectable exterior wall inwardly from a first shape to a second shape along the entire horizontally extending projection when the door is closed, whereby a continuous seal is formed and maintained which wraps the horizontally extending projection on both its horizontal and vertical edges even when the door and sill are misaligned.

2. An improved bottom and sill assembly, according to claim 1, including a downwardly extending lip spaced from said sealing member and positioned adjacent the exterior of such door.

3. An improved bottom and sill assembly as described in claim 2, wherein said bottom assembly includes a flat base of substantially the same area and shape as the bottom of such door, said lip being located adjacent one edge of said flat base and said sealing member being located adjacent the other edge of said base.

4. An improved bottom and sill assembly as described in claim 1, wherein said sealing member includes a longitudinally extending compressible foam material.

5. An improved bottom and sill assembly as described in claim 1, wherein said sealing member is removably attached.

6. An improved bottom and sill thermal barrier assembly as described in claim 1, wherein said sill assembly includes an impervious ramp member sloping downwardly toward the exterior and a thermal break member adjacent said ramp, said thermal break member defining said horizontally extending projection.

7. An improved bottom and sill assembly as described in claim 6, wherein said impervious ramp member defines a channel, said thermal break member having a depending leg, wherein said depending leg is received by said channel.

8. An improved door bottom and sill assembly for inswing exterior doors comprising:

a bottom assembly for mounting to the bottom of such door, said bottom assembly being integrally comprised of a flat base of substantially the same area and shape as the bottom of such door, a lip mounted adjacent the exterior edge of said base member and projecting downwardly, a generally tubular sealing member mounted adjacent said side wall, said sealing member having a flexible and deflectable exterior wall extending horizontally along the bottom of such door, said sealing member extending downwardly from the bottom of such door, a sill asssembly positioned below such door bottom, said sill assembly including a weather-impervious ramp and a horizontal mating member having horizontal and vertical edges for engaging said flexible and deflectable sealing member thereby providing a weather seal, said flexible sealing member extending downwardly to an elevation below said horizontal mating member, said mating member deflecting said flexible and deflectable exterior wall inwardly from a first shape to a second shape along the entire horizontal mating member when the door is closed, whereby a continuous weather seal is formed which wraps said horizontal mating member on both its horizontal and vertical edges and remains effective even if the door bottom assembly and sill assembly are misaligned with respect to each other.

9. An improved door bottom and sill assembly as described in claim 8, wherein said sill assembly includes a thermal barrier member adjacent said ramp, said thermal barrier member defining said horizontal mating member.

10. An improved door bottom and sill assembly as described in claim 9, including a integral upstanding dam wall on said ramp adjacent said thermal barrier member.
