Threshold assembly for an entryway system

1. A threshold assembly for use with an entryway disposed within an aperture of a structure, which has an exterior and an interior and includes a door panel moveable between open and closed positions, said threshold assembly comprising:

a sill extending between an exterior side for facing the exterior of the structure and an interior side for facing the interior of the structure with said sill presenting an upper sill surface extending from said exterior side to said interior side and configured to face the door in the closed position;

a rail coupled to and disposed above said upper sill surface of said sill, with said rail movable relative to said upper sill surface between an initial position when the door is in the open position, and a second position different from said initial position when the door is in the closed position;

wherein said rail presents a lower rail surface facing said upper sill surface and has first and second retaining arms spaced from one another and extending toward said upper sill surface, with each of said retaining arms including a first leg that extends towards an opposite retaining arm, and one of said retaining arms including a second leg extending away from the other of said retaining arms, with said second leg configured to prevent said rail from articulating beyond said initial position when the door is in the open position; and

a biasing member configured to engage said rail for biasing said rail from said second position toward said initial position, with said biasing member retained between said first leg of said first retaining arm and said first leg of said second retaining arm.

2. The threshold assembly of claim 1 further comprising a third arm and a fourth arm extending from said rail towards said upper sill surface, with said third and fourth arms cooperating to at least partially define a channel.

3. The threshold assembly of claim 2 further comprising a projection extending from said upper sill surface toward said rail and into said channel, wherein said rail articulates about said projection.

4. The threshold assembly of claim 3 wherein said projection extends to a distal end and said distal end is in contact with said rail when said rail is in said initial position and said second position.

5. The threshold assembly of claim 1 further comprising a nosing coupled to said sill and configured to contact said rail when said rail is in said initial position.

6. The threshold assembly set forth in claim 5 wherein said rail and said nosing are configured to cooperate and prevent said biasing member from articulating said rail beyond said initial position.

7. The threshold assembly of claim 6 wherein said rail articulates towards said nosing as said rail articulates from said second position towards said initial position.

8. The threshold assembly of claim 1 wherein said sill further comprises a protrusion extending towards said rail, with said protrusion including a lip extending towards said second leg.

9. The threshold assembly of claim 8 wherein said lip of said protrusion cooperates with said second leg of said first or second retaining arms to prevent said rail from articulating beyond said initial position when the door is in the open position.

10. A threshold assembly for use with an entryway disposed within an aperture of a structure, which has an exterior and an interior and includes a door panel moveable between open and closed positions, said threshold assembly comprising:

a sill extending between an exterior side for facing the exterior of the structure and an interior side for facing the interior of the structure with said sill presenting an upper sill surface extending from said exterior side to said interior side and configured to face the door in the closed position;

a rail coupled to and disposed above said upper sill surface of said sill, with said rail movable relative to said upper sill surface between an initial position when the door is in the open position, and a second position different from said initial position when the door is in the closed position;

wherein said rail presents a lower rail surface facing said upper sill surface, with said rail comprising,

a first retaining arm and a second retaining arm spaced from each other, with said first and second retaining arms extending from said rail towards said upper sill surface and with each of said retaining arms including a first leg extending towards an opposite retaining arm, and one of said retaining arms including a second leg extending away from an opposite retaining arm, with said second leg configured to prevent said rail from articulating beyond said initial position when the door is in the open position, and

a third arm and a fourth arm extending from said rail towards said upper sill surface, with said third and fourth arms cooperating to at least partially define a channel;

a biasing member configured to engage said rail for biasing said rail from said second position toward said initial position, with said biasing member retained between said first leg of said first retaining arm and said first leg of said second retaining arm;

a projection extending from said upper sill surface toward said rail and into said channel, wherein said rail articulates about said projection and wherein said projection extends to a distal end and said distal end is in contact with said rail when said rail is in said initial position and said second position; and

a nosing configured to contact said rail when said rail is in said initial position.

11. The threshold assembly of claim 10 wherein said rail articulates towards said nosing as said rail articulates from said second position towards said initial position.

12. The threshold assembly of claim 10 wherein said sill further comprises a protrusion extending towards said rail, with said protrusion including a lip extending towards said second leg.

13. The threshold assembly of claim 12 wherein said lip of said protrusion cooperates with said second leg of said first or second retaining arms to prevent said rail from articulating beyond said initial position when the door is in the open position.

14. The threshold assembly of claim 10 wherein said biasing member is integral with said rail.

15. The threshold assembly of claim 10 wherein said rail is rigid.

16. A threshold assembly for use with an entryway disposed within an aperture of a structure, which has an exterior and an interior and includes a door panel moveable between open and closed positions, said threshold assembly comprising:

a sill extending between an exterior side for facing the exterior of the structure and an interior side for facing the interior of the structure with said sill presenting an upper sill surface extending from said exterior side to said interior side and configured to face the door panel in the closed position;

a rail supported above said upper sill surface of said sill between an initial position when the door panel is in the open position, and a second position different from said initial position when the door panel is in the closed position;

a biasing member configured to engage said rail for biasing said rail from said second position toward said initial position;

wherein said rail comprises a first arm and a second arm extending toward said upper sill surface with said biasing member located between said first and second arms with at least one of said first or second arms including a lip configured to prevent said biasing member from articulating said rail past said initial position when the door is in the open position; and

a nosing configured to abut said rail at said initial position to further prevent said rail from articulating beyond said initial position when the door is in said open position.

17. The threshold assembly of claim 16 wherein said rail articulates towards said nosing as said rail articulates from said second position towards said initial position.

18. The threshold assembly of claim 16 wherein said sill further comprises a protrusion extending towards said rail, with said protrusion including a lip extending towards said lip of said first or second arm of said rail, wherein said lip of said protrusion and said lip of said first or second arm cooperate to prevent said rail from articulating beyond said initial position when the door is in the open position.

19. The threshold assembly of claim 16 wherein said projection maintains contact with said rail as said rail articulates between said initial and second positions.

20. The threshold assembly of claim 16 wherein said rail is rigid.
