Abstract

An anti-sputtering sill system for a window or door frame and a method of controlling sputtering associated with a sill of the window or door frame. The anti-sputtering sill systems may reduce or prevent sputtering by preferentially allowing air bubbles formed in the water in a containment tank in the sill to pass into a vent cavity in the sill that is vented to the interior of a building.

First claim

What is claimed is:

1. An anti-sputtering sill system comprising:
a closure frame comprising first and second side jambs connected to each other by a head jamb and a sill, wherein each of the first and second side jambs and the sill comprise an interior side and an exterior side, and wherein the sill comprises a rail extending between the first and second side jambs;
a panel retained in the frame, the panel positioned above and supported by the rail, wherein the panel is retained between the first and second side jambs;
an interior cavity located in the first side jamb;
a trough located in the sill, the trough configured to contain water between the interior side and the exterior side of the sill, wherein the trough is located between the interior side of the sill and the rail supporting the panel;
a containment tank located in the sill below the trough;
a vent cavity in the sill, the vent cavity in fluid communication with the containment tank through a containment tank vent, wherein at least a portion of the vent cavity is located above the containment tank vent and the containment tank;
a first jamb vent located in a top surface of the rail, the first jamb vent being located between the vent cavity and the interior cavity in the first side jamb, wherein the vent cavity is in fluid communication with the interior cavity of the first side jamb through the first jamb vent, and wherein the first jamb vent is located above the containment tank vent such that fluid passing into the interior cavity in the first side jamb from the containment tank must pass through the containment tank vent and the vent cavity before passing through the first jamb vent into the interior cavity in the first side jamb;
a trough drain located between the trough and the containment tank, wherein the water in the trough drains into the containment tank through the trough drain, and wherein the trough drain comprises a conduit comprising an upper opening and a lower opening, wherein the water draining from the trough into the containment tank enters the conduit through the upper opening and leaves the conduit to enter the containment tank through the lower opening, wherein the lower opening is located in the containment tank below the containment tank vent; and
an exterior drain in the sill, the exterior drain configured to drain water in the containment tank to the exterior side of the sill.

2. A sill system according to claim 1 , wherein the second side jamb comprises an interior cavity located therein, wherein a second jamb vent is located between the vent cavity and the interior cavity in the second side jamb such that the vent cavity is in fluid communication with the interior cavity of the second side jamb through the second jamb vent.

3. A sill system according to claim 1 , wherein the conduit is a drain insert.

4. A sill system according to claim 1 , wherein the lower opening is located closer to a bottom of the containment tank than the containment tank vent.

5. A sill system according to claim 1 , wherein the sill comprises exterior trim attachment features configured to retain exterior trim on the sill, wherein the exterior drain is located above the exterior trim attachment features.

6. A sill system according to claim 1 , wherein the panel comprises a horizontally sliding panel configured to move horizontally between the first and second side jamb s.

7. A sill system according to claim 6 , wherein the horizontally sliding panel is configured to move between a closed position in which the horizontally sliding panel seals against the first side jamb and an open position in which an opening is provided in the frame between the horizontally sliding panel and the first side jamb, and wherein the trough drain is located below the horizontally sliding panel when the horizontally sliding panel is in the closed position.

8. A sill system according to claim 7 , wherein the sill system comprises a plurality of trough drains, and wherein the plurality of trough drains are located below the horizontally sliding panel when the horizontally sliding panel is in the closed position.

9. A sill system according to claim 7 , further comprising a containment tank dam located in the containment tank between the first and second side jambs, wherein the containment tank dam is configured to restrict the water located in the containment tank between the first side jamb and the containment tank dam from flowing through the containment tank to the second side jamb.

10. A sill system according to claim 7 , further comprising a second panel mounted in the frame, wherein the second panel forms a seal with the second side jamb, and further wherein a trough dam is located in the trough below a junction between the horizontally sliding panel and the second panel when the horizontally sliding panel is in the closed position, wherein the trough dam is configured to restrict the water located in the trough between the second side jamb and the trough dam from flowing through the trough to the first side jamb.

11. A sill system according to claim 10 that, further comprising a containment tank dam located in the containment tank between the first and second side jambs, wherein the containment tank dam is configured to restrict the water located in the containment tank between the first side jamb and the containment tank dam from flowing through the containment tank to the second side jamb, wherein the containment tank dam and the trough dam are aligned with each other between the first and second side jambs.

12. An anti-sputtering sill system comprising:
a closure frame comprising first and second side jambs connected to each other by a head jamb and a sill, wherein each of the, first and second side jambs, and the sill comprise an interior side and an exterior side, and wherein the sill comprises a rail extending between the first and second side jambs;
a first panel retained in the frame, the first panel positioned above and supported by the rail, wherein the first panel is retained between the first and second side jambs, wherein the first panel comprises a horizontally sliding panel configured to move horizontally between the first and second side jambs, and wherein the first panel is configured to move between a closed position in which the first panel seals against the first side jamb and an open position in which an opening is provided in the frame between the first panel and the first side jamb;
a second panel mounted in the frame, the second panel positioned above the sill and between the first and second side jambs, wherein the second panel forms a seal with the second side jamb;
an interior cavity located in the first side jamb; wherein the interior cavity is configured
a trough located in the sill, the trough configured to contain water between the interior side and the exterior side of the sill;
a containment tank located in the sill below the trough;
a containment tank dam located in the containment tank between the first and second side jambs, wherein the containment tank dam is configured to restrict water located in the containment tank between the first side jamb and the containment tank dam from flowing through the containment tank to the second side jamb;
a vent cavity in the sill, the vent cavity in fluid communication with the containment tank through a containment tank vent, wherein at least a portion of the vent cavity is located above the containment tank vent and the containment tank;
a first jamb vent located in a top surface of the rail, the first jamb vent being located between the vent cavity and the interior cavity in the first side jamb, wherein the vent cavity is in fluid communication with th
