Self-draining panel threshold combination
First Claim
1. An improved self-draining panel threshold combination comprising:
- a door frame including a threshold for a panel movable between open and closed positions, the frame surrounding the peripheral edges of the panel in its closed position;
weatherseals in the frame and threshold lying in a common weatherseal plane for flexing and sealingly engaging the panel in its closed position;
a water trough in the threshold having a fully open end extending from one end of the threshold to the other end thereof and lying substantially in the weatherseal plane for catching water that is blown into and past the weatherseals and runs along the panel edges into the open end of the water trough;
the threshold weatherseal further having a portion thereof extending across the open end of the water trough to prevent foreign material from entering the trough when the panel is in its open position and the weatherseal is unflexed; and
drainage means in the threshold for draining water entering the water trough out of the threshold.

Abstract
An improved self-draining panel threshold combination for a panel such as a door or the like which is of simple design and construction, and passes industry air and water penetration requirements without the use of separate corner seals or door bottom seals. The door threshhold combination comprises weatherseals around the entire periphery of the door lying in a weatherseal plane. An open-ended water trough in the threshold extends from one jamb to the other and lies substantially in the weatherseal plane for catching any water that leaks into and past the weatherseals. The threshold has a weatherseal adjacent the water trough that is adapted when flexed by the closed door to allow entry of water into the open end of the water through, and when unflexed upon movement of the door to its open position to cover the open end to prevent foreign material from entering the trough. A drainage system is provided for draining water entering the water trough out of the threshold.

7. An improved self-draining threshold for a panel such as a door comprising:
-
a base plate; a first sill member comprising a part of the base plate and having a first wall extending upwardly from the base plate; a second sill member comprising a part of the base plate adjacent the first sill member and having a second wall extending upwardly from the base plate and spaced from the first wall to form a water trough having an open end for receiving water; an elongate weatherseal having a mounting leg and a second panel engaging leg wherein the mounting leg is mountable on the first wall and the panel engaging leg in its unflexed condition extends across the open end of the water trough into substantial engagement with the second wall to prevent foreign material from entering the trough; and drainage means in the threshold for draining water entering the water trough out of the threshold. - View Dependent Claims (8, 9, 10, 11, 12)
