Abstract

A self-draining hollow threshold for an out-swinging door of an enclosure, such as a room, is disclosed comprising an interior threshold portion extending into the enclosure, and having an upper wall. The interior threshold portion has a drainage system comprising a slot in the upper wall, for draining water that penetrates the plane of the door. Such water flows over the upper wall and through the hollow threshold to the exterior of the door and enclosure.

Claims

1. A self-draining threshold for an out-swinging door leading into an enclosure comprising:

a hollow exterior threshold portion extending toward the exterior of the enclosure such that upon the opening and closing of the door, a portion of the door passes over the exterior threshold portion;

a hollow interior threshold portion extending away from the door into the interior of the enclosure and having an upper wall; and

drainage means in the threshold comprising a slot in the upper wall of the interior threshold portion for draining water from the interior of the enclosure to the exterior of the enclosure, such that water which penetrates the plane of the door to the interior of the enclosure flows over the upper wall, into and through the slot and hollow threshold to the exterior thereof.

2. A self-draining threshold for an out-swinging door according to claim 1, and further comprising an elongate weatherseal, and means for mounting the weatherseal between the lower end of the door and the interior threshold portion.

3. A self-draining threshold for an out-swinging door according to claim 2, wherein the weatherseal mounting means comprises an elongate blind recess in the interior threshold portion for receiving the weatherseal, and the slot of the drainage means extends through the upper wall.

4. A self-draining threshold for an out-swinging door leading into an enclosure comprising:

a hollow exterior threshold portion extending toward the exterior of the enclosure;

a hollow interior threshold portion extending away from the door into the interior of the enclosure and having an upper wall;

drainage means in the threshold comprising a slot in the upper wall of the interior threshold portion for draining water that penetrates the plane of the door, such that the water flows over the upper wall, into and through the slot and hollow threshold to the exterior thereof;

an elongate weatherseal; and

means for mounting the weatherseal between the lower end of the door and the interior threshold portion;

wherein the upper wall of the interior threshold portion comprises front and rear adjoining upper wall sections, wherein the weatherseal mounting means comprises an elongate recess on the interior threshold portion for receiving the weatherseal, wherein the slot of the drainage means extends through the upper wall substantially at the juncture of the front and rear upper wall sections, and wherein the drainage means further comprises a passage in the threshold portion, for allowing water entering the hollow threshold to flow out the exterior thereof.

5. A self-draining threshold for an out-swinging door leading into an enclosure comprising:

a hollow exterior threshold portion extending toward the exterior of the enclosure;

a hollow interior threshold portion extending away from the door into the interior of the enclosure and having an upper wall;

drainage means in the threshold comprising a slot in the upper wall of the interior threshold portion for draining water that penetrates the plane of the door, such that the water flows over the upper wall, into and through the slot and hollow threshold to the exterior thereof;

an elongate weatherseal; and

means for mounting the weatherseal between the lower end of the door and the interior threshold portion;

wherein the upper wall of the interior threshold portion comprises front and rear adjoining upper wall sections, wherein the weatherseal mounting means comprises an elongate recess on the interior threshold portion for receiving the weatherseal, wherein the opening of the drainage means extends through the upper wall substantially at the juncture of the front and rear upper wall sections, and wherein the drainage means further comprises a passage in the threshold portion, for allowing water entering the hollow threshold to flow out the exterior thereof;

wherein the threshold has a base, wherein the rear upper wall section terminates in a shoulder facing the door, and the elongate recess is located in the shoulder, and wherein the upper wall section is inclined downwardly towards the drainage opening.
