Door entryway system
View Patent ↗A door entryway system is disclosed. The door entryway system may have a door sweep capable of attachment to a bottom of a door panel and a threshold assembly. The threshold assembly may include a threshold substrate, an upwardly open sill channel on the substrate and a substantially rigid threshold cap biased upwardly, and vertically adjustable by rotating during interaction with the door sweep. The threshold cap and door sweep contact to form a sealing barrier when the door panel is in a closed position. The threshold assembly may also include a cap base formed separate from the threshold cap, the cap base at least partially positioned within the sill channel, the cap base supporting the threshold cap.
1. A door entryway system, comprising:
a door sweep capable of attachment to a bottom of a door panel; and
a threshold assembly comprising:
a threshold substrate;
an upwardly open sill channel on the substrate;
a substantially rigid threshold cap biased upwardly and vertically adjustable by rotating during interaction with the door sweep such that the threshold cap and door sweep directly contact to form a sealing barrier when the door panel is in a closed position, the threshold cap is at least partially disposed in, or above, the sill channel; and
a cap base formed separate from the threshold cap, the cap base at least partially positioned within the sill channel, the cap base configured to support the threshold cap.
2. The door entryway system according to claim 1 , wherein the door sweep comprises a resilient sealing provision.
3. The door entryway system according to claim 2 , wherein the sealing provision comprises at least one resilient bulb.
4. The door entryway system according to claim 3 , wherein the door sweep further comprises at least one rigid arm extending toward the threshold assembly when the door panel is in the closed position.
5. The door entryway system according to claim 1 , comprising a biasing spring positioned between the cap base and the threshold cap for biasing the threshold cap upward.
6. The door entryway system according to claim 5 , wherein the base comprises the spring.
7. The door entryway system according to claim 1 , wherein the threshold cap comprises a top wall for forming the sealing barrier, and a locking wall extending substantially perpendicularly from the top wall.
8. The door entryway system according to claim 7 , wherein the locking wall comprises a projection extending therefrom.
9. The door entryway system according to claim 8 , wherein the cap base comprises a stop, for interacting with the projection of the locking wall to limit the upward travel of the threshold cap.
10. The door entryway system according to claim 1 , wherein the sill channel is at least partially defined by a dam on an exterior side thereof; and
the threshold cap further comprises a projection, the projection configured to extend above and in front of the dam.
11. The door entryway system according to claim 10 , wherein the projection is configured to seal with the dam.
12. A door entryway system, comprising:
a threshold assembly configured to sealingly interact with one of a door panel or a door sweep, the threshold assembly comprising:
a nosing defining one side of an upwardly open sill channel;
a substrate at least partially defining a floor of the sill channel;
a dam defining an opposite side of the sill channel; and
a substantially rigid threshold cap engaged with at least one support base,
the support base positioned substantially between the floor of the upwardly open sill channel and the threshold cap, the threshold cap being configured to be biased upwardly, and vertically adjustable while directly contacting with either the door panel or door sweep to form a sealing barrier when the door panel is in a closed position;
wherein the threshold cap includes an upper surface having an interior portion and an exterior portion, one of the interior portion or the exterior portion moving vertically by a greater magnitude than another of the interior portion or the exterior portion while the upper surface interacts with either the door panel or the door sweep.
13. The door entryway system according to claim 12 , comprising a biasing spring positioned between the support base and the threshold cap for biasing the threshold cap upward.
14. The door entryway system according to claim 13 , wherein the support base comprises the spring.
15. The door entryway system according to claim 12 , wherein the threshold cap comprises a top wall for forming the sealing barrier, and a locking wall extending substantially perpendicularly from the top wall.
16. The door entryway system according to claim 15 , wherein the locking wall comprises a projection extending therefrom.
17. The door entryway system according to claim 16 , wherein the support base comprises a stop, for interacting with the projection of the locking wall to limit the upward travel of the threshold cap.
18. The door entryway system according to claim 12 , wherein the threshold cap further comprises a projection, the projection configured to extend above and in front of the dam.
19. The door entryway system according to claim 18 , wherein the projection is configured to seal with the dam.
20. A door entryway system, comprising:
a door sweep capable of attachment to a bottom of a door panel; and
a threshold assembly comprising:
a nosing defining one side of an upwardly open sill channel;
a substrate at least partially defining a floor of the sill channel;
a dam defining an opposite side of the sill channel; and
a substantially rigid threshold cap biased upwardly and vertically adjustable during interaction with the door sweep, the threshold cap at least partially disposed in, or above, the sill channel,
wherein the door sweep comprises at least one substantially rigid portion for deflecting the threshold cap downwardly as the door panel approaches a closed position, and
wherein the door sweep comprises at least one resilient portion to directly contact the threshold cap to form a sealing barrier when the door panel is in the closed position.
