Abstract: A sliding door assembly has a frame with a movable panel and a fixed panel. The movable panel has a pair of rollers that roll along a header located above the panels with the rollers attached to the movable panel via posts that pass through a channel on the header. The posts pass through a curved section of the channel whenever the movable panel is proximate its closed position and a straight section of channel when the movable panel is traveling laterally. The movable panel presses against a gasket located on the frame components surrounding the movable panel wherein one or more latches press the movable panel against the gasket whenever this panel is in the closed position. Valve is positioned within a weep hole on the threshold in order to prevent water from seeping into the building via the bottom of the door assembly.

Abstract: A sliding door has a sash suspended from a top leg of a frame by having a curved channel extend along this leg and providing the sash with a post that passes through the channel and a roller attached to the post, such that the roller sits on the leg and permits the sash to slide relative to the frame. In closing the door, the sash moves towards the inner portion of the frame and is pressed against a compression gasket that extends about the inner portion of the door in order provide an airtight seal between the sash and the frame. A handle is operatively connected to a dog that is attached to the frame which dog acts on an inner wall of a jamb on the frame in order to maintain the seal.
