Abstract: A self draining door threshold includes a wedge-shaped silicone check valve in communication with a water reservoir on the interior side. The check valve is normally closed but will yieldably open in response to water pressure which overcomes the resilience of the silicone material and the air pressure on the top wall of the wege-shaped passageway. The check valve functions as a seal against incoming air but will open to allow escape of water as needed. The silicone material seals around foreign material in the valve making it air tight. The bottom edge of the door includes moisture resistant material having an upwardly extending portion received in a groove. The exterior side of the door is also covered with moisture resistant material which has inwardly extending portions received in a vertical groove between abutting panels.

Abstract: An improved threshold assembly for mounting on a door and a door sill is described which includes a sill-mounted portion with a threshold plate formed of nonmagnetically attracted material and a door-mounted portion with a door cap for mounting on the bottom edge of the door with a flexible magnet-holding device. Two elongated magnets are mounted one in each portion of the threshold assembly, and, when the door is in the closed position, the magnets are positioned one on top of the other. The magnets are structured so that the opposite edges have opposite polarity and are mounted with adjacent magnet edges having unlike polarity. During closing of the door, the edges of like polarity approach and repel one another and causes the magnet-holding device to move away from the threshold plate.

Abstract: An improved door bottom and sill assembly for inswing exterior doors is disclosed. The door bottom and sill assembly consists of a bottom portion and a sill portion. The bottom portion has a sealing member along the interior bottom edge of the door.

Abstract: A sealing system for an entry door incorporates a threshold member having a longitudinally extending open-ended channel in its upper surface. The sweep utilizes a double vertical seal design which encloses the channel when the door is shut. The first seal contacts exterior portions of the channel whereas the second seal contacts interior portions of the channel. The channel is vented through the threshold so that the pressure on both sides of the first seal is equalized to minimize water seepage, while the second seal completely blocks the outside air from the interior of the building. The threshold is preferably of a two piece construction which may be snapped together to thereby minimize manufacturing and installation costs.

Abstract: A sweep for the bottom of a swingable door includes an L-shaped elongated member having an elongated tube extending along the upper surface of the horizontal portion and a plurality of resilient ribs extending downwardly therefrom. The sweep is mounted on a door by attaching the vertical leg to the inner surface of the door with the tube between the bottom edge of the door and the horizontal leg. The depending ribs contact and are bent by contact with a sill at the bottom of the opening in which the door is mounted. The sweep is usable on inwardly or outwardly swinging doors.

Abstract: A weather sealing arrangement for a gap between first and second elongate structural members of which a door equipped with a weatherboard, and a sill, are examples, in which the weatherboard supports an elongate seal therealong which has a resiliently supported protruding portion for sealing a gap between the weatherboard and the sill when the door is in a closed condition, and the sill provides a weather strip which extends along the sill and protrudes therefrom. During hingeing movement of the door from the closed condition to an open condition, the protruding seal passes through an intermediate condition in which the seal portion traverses the weather strip so that the whole length of the seal portion is wiped by the weather strip and rainwater will tend to be wiped off the seal portion and so be kept outdoors. The weather strip is in the form of a rib which may be elastomeric and removably secured to the sill, or formed on it and be moulded with the sill.

Abstract: To replace the customary wood bottom rail of a foam-filled metal skinned door, a prefabricated metallic bottom rail and Neoprene bottom sweep unit is utilized. The unit forms a closure for the bottom of the door panel during foaming and provides a better bond with the foam core and better anchorage therein.

Abstract: A flat, hollow, vertically elongated door panel has an open bottom. A movable piece is located inside the panel and can move up or down through the bottom. Horizontal bottom pieces are attached to the movable piece and both the bottom and movable pieces are spring-loaded downwardly.

Abstract: An improved weathersealed door system includes a sill and a cooperating weatherseal member which has a tubular depending portion deflected by the sill in the closed position so as to provide firm surface engagement therewith. A header weatherseal member extends across the top edge of the door and is also resiliently deflected in the closed position of the door. Extending vertically along the hinge side of the door is a first hinge jamb weatherseal member which seats against the surface of the door in its closed position, and a second hinge jamb weatherseal member extends upwardly from the sill and is fabricated of highly compressible material of greater thickness than the space between the side edge of the door and the jamb. As a result, it is compressed by both the side edge of the door and the sill weatherseal member when the door is in its closed position.
