Entry system with water infiltration barrier

Abstract

The present application discloses embodiments of entry systems that minimize water infiltration due to a wind driven rain. In one embodiment, the entry system includes a corner pad that includes an upper portion that seals against the weather strip when the door is closed and a lower portion that is spaced apart from the weather strip to form a gap between the lower portion and the weather strip. The lower portion seals against the door when the door is closed.

Claims

1. An entryway comprising: a vertical door jamb having a bottom end;a stop extending along the door jamb;a door hingedly connected to the vertical door jamb;a weather strip extending along the stop, the weather strip includes first leg that is positioned against the stop and a second leg that seals against the door when the door is closed;a seal attached to the bottom end of the vertical door jamb, the seal including an upper portion that seals against the weather strip when the door is closed and a lower portion that is spaced apart from the weather strip to form a gap between the lower portion and the weather strip, and wherein the lower portion seals against the door when the door is closed.

2. The entryway of claim 1 wherein the gap is larger than a distance that can be spanned by a drop of water.

3. The entryway of claim 1 wherein the seal has a tapered cross-section.

4. The entryway of claim 1 wherein the seal is attached to the doorjamb with an adhesive.

5. The entryway of claim 1 wherein the seal is formed of a foam polymer material.

6. The entryway of claim 5 further comprising a polymer film that covers the foam polymer material.

7. The entryway of claim 1 further comprising a tape with adhesive on two sides of said tape that adhesively attaches the seal to the door jamb.

8. The entryway of claim 1 wherein the seal has a main generally rectangular body having a generally vertical forward edge and an upper forward corner protrusion which extends from the main body toward the weather strip.

9. The entryway of claim 8 wherein a lower edge of the forward corner protrusion is located at least one inch above a lower edge of the body.

10. The entryway of claim 8 wherein a lower edge of the forward corner protrusion is located above the level of wind driven water.

11. The entryway of claim 8 wherein a lower edge of the forward corner protrusion is located 2 inches to 4 inches above a lower edge of the pad.

12. A corner seal for installation in the lower corner of an entryway door jamb adjacent to the jamb vertical weather strip and directly atop the sill threshold to prevent infiltration of wind driven water, the corner seal comprising: a thin generally planar body formed of a compressible elastic material sized to sealingly fit between the door jam and the outer periphery of a door when closed, the body having;a planar mounting face for adhesively mounting to the body to the door jamb adjacent to the weather strip and above the sill threshold;a forward edge in the region immediately above the sill threshold which is located inboard of the weather strip when the door is closed, the body further having an upward forward edge protrusion which extends outward into engagement with the weather strip to form a substantially tight seal when the door is closed; andan exposed generally planar face for engaging the door peripheral edge and a lower edge which sealingly abuts the sill threshold when the door is closed.

13. The corner seal of claim 12 wherein the seal body is a mild taper with the body being thicker adjacent the outboard edge proximate the weather strip than the inboard edge.

14. The corner seal of claim 12 wherein the body is formed of a foam polymer material.

15. The corner seal of claim 14 wherein the body further comprises a polymer film covering the foam polymer material which forms an elastic core.

16. The corner seal of claim 12 further comprising a two-sided adhesive layer applied to the body mounting face for adhesively attaching the body to a door jamb.

17. The corner seal of claim 12 wherein the body has a main generally rectangular body member having a generally vertical forward edge and an upper forward corner protrusion which extends from the main body member in the direction of the weather strip.

18. The corner seal of claim 17 wherein the protrusion is located at least one inch above the lower edge of the body so that the protrusion is above the level of wind driven water.

19. The corner seal of claim 17 wherein the lower edge of the protrusion is located 2″ to 4″ above the lower seal edge.

20. An entryway comprising: a vertical door jamb having a bottom end;a stop extending along the door jamb;a door hingedly connected to the vertical door jamb;a weather strip extending along the stop, the weather strip includes first leg that is positioned against the stop, a second leg that seals against the door when the door is closed, and a channel defined there between;means for inhibiting wicking of water up said channel.

21. A method providing a seal between a lower end of a door jamb and a lower end of door while inhibiting wicking of water up a channel defined between two legs of a door weather strip comprising: attaching a corner seal to a door jamb such that a lower portion of the corner seal is spaced apart from the weather strip to form a gap that is too large to span with a drop of water and such that an upper portion of the corner seal engages the weather strip.
