  • Patent number: 5018307
    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.

  • Patent number: 4831779
    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.

  • Patent number: 4742646
    Abstract: A panel and frame weatherseal combination is disclosed for sealing the marginal edges of a panel closing an opening defined by a frame, with particular utility for sealing the corner areas thereof. The panel has an exterior surface facing the outdoors. The weatherseal comprises a longitudinally extending backing strip of a generally uniform cross-section throughout its length, to which a plurality of spaced-apart longitudinally extending flexible barrier fins are affixed longitudinally along and transversly extend from the backing strip. The innermost barrier fin extends past the marginal edges of the exterior surface. Any outdoor air movement or the like impinging on the exterior surface presses the innermost barrier fin into sealing engagement with the marginal edges of the exterior surface. At the corners of the panel and frame, the barrier fins are interdigitated to provide an excellent corner seal.
