Abstract

A door sill assembly comprises a door sill comprising a sill crown having one or more upper drain apertures therein, a sill tread defining a stepping surface, and an internal support at least partially supporting the sill crown and the sill tread and having a drainage surface. At least a portion of the drainage surface is sloped, and at least one of the sill tread and the internal support has one or more lower drain apertures therein. The drainage surface defines at least one internal drainage channel in fluid communication with at least one upper drain aperture and at least one lower drain aperture. At least one of the sill crown, the sill tread, and the internal support is separately formed.

Claims

1. A door sill assembly, comprising:

a door sill comprising;

a sill crown having one or more upper drain apertures therein,

a sill tread defining a stepping surface, and

an internal support at least partially supporting the sill crown and the sill tread and having a drainage surface, at least a portion of the drainage surface being sloped, at least one of the sill tread and the internal support having one or more lower drain apertures therein, the drainage surface defining at least one internal drainage channel in fluid communication with at least one upper drain aperture and at least one lower drain aperture,

at least one of the sill crown, the sill tread, and the internal support being separately formed.

2. The door sill assembly of claim 1, wherein the door sill further comprises an upwardly extending longitudinal rib, the upper drain apertures being interiorly adjacent the longitudinal rib.

3. The door sill assembly of claim 2, wherein the door sill further comprises a longitudinal seal disposed along the longitudinal rib.

4. The door sill assembly of claim 3, further comprising:

a door sweep configured to be fitted to the bottom of a door.

5. The door sill assembly of claim 4, wherein the door sweep comprises a downwardly depending longitudinal tab configured to cooperate with the longitudinal seal for providing a fluid barrier.

6. The door sill assembly of claim 4, wherein the door sweep further comprises an inclined longitudinal deflector sized to extend beyond the upwardly extending rib when the door is in a closed position.

7. The door sill assembly of claim 4, wherein the door sweep further comprises one or more downwardly depending flaps for engaging the sill crown.

8. The door sill assembly of claim 1, wherein the sill crown and the sill tread are separately formed and connected to each other.

9. The door sill assembly of claim 1, wherein the door sill further comprises a plurality of setting blocks disposed on the drainage surface for supporting at least the sill tread.

10. The door sill assembly of claim 1, wherein the door sill further comprises a transverse seal at each longitudinal end of the drainage surface for providing a fluid barrier.

11. The door sill assembly of claim 1, wherein the door sill further comprises a sill base at least partially supporting the internal support.

12. The door sill assembly of claim 11, wherein the sill base is formed integrally with the internal support.

13. The door sill assembly of claim 11, wherein the sill base is separately formed.

14. The door sill assembly of claim 11, wherein the sill base comprises a machined board.

15. A door sill comprising:

a sill crown having one or more upper drain apertures therein;

a sill tread defining a stepping surface; and

an internal support at least partially supporting the sill crown and the sill tread and having a drainage surface, at least a portion of the drainage surface being sloped, at least one of the sill tread and the internal support having one or more lower drain apertures therein, the drainage surface defining at least one internal drainage channel in fluid communication with at least one upper drain aperture and at least one lower drain aperture,

at least one of the sill tread, the sill crown and the internal support being separately formed.

16. A kit for assembling the door sill of claim 15.

17. A door sill assembly, comprising:

a door sill comprising;

an upwardly extending longitudinal rib, and

a longitudinal seal disposed along an interior-facing surface of the longitudinal rib; and

a door sweep configured to be fitted to a bottom of an interior-swinging door, the door sweep comprising a downwardly depending longitudinal tab configured to abut the longitudinal seal for providing a fluid barrier.

18. The door sill assembly of claim 17, wherein the door sweep further comprises one or more downwardly depending flaps for engaging the door sill.

19. The door sill assembly of claim 17, wherein the door sweep further comprises an inclined longitudinal deflector sized to extend beyond the upwardly extending rib when the door is in a closed position.

20. The door sill assembly of claim 17, wherein the door sill further comprises:

a sill tread defining a stepping surface, and

a sill crown,

one of the sill tread and the sill crown comprising the longitudinal rib and the longitudinal seal.
