Abstract: A panel or door suspension system used to hang sliding panels or doors. The panel members are hung by an upper bearing assembly with bearings on each side of the longitudinal axis of the panel thereby allowing the weight of the door to bear wholly on the upper bearings and to act centrally and downwardly between the bearings thereby preventing a moment on the bearings. A wedge member attached to the upper portion of the panel allows for vertical adjustment of the panel relative to the bearings and the door frame. A sill assembly beneath the panel allows for stable sliding operation of the panel member, provides for debris drainage and facilitates servicing of the members comprising the sill assembly.

Abstract: A hanging panel assembly utilises a core which is encompassed by a press fit material installed by the user generally without mechanical attachments. A series for further members are subsequently connected to the press fit material using a snap-lock type connection. A locking mechanism is used with the hanging panel assembly which utilises a longitudinal latch operated by a rotating handle. An interference member dictates whether the longitudinal member may be moved. A disabling assembly moves the interference member out of engagement and allows the door to be opened from the inside without the necessity of inserting a key into the lock.
