Abstract: A hanging panel system which utilizes a bearing assembly for movement in a horizontal plane. The panel system utilizes a load carrying member about the periphery of the panel and an inside and outside material which define the inside and outside surfaces of the panel system. The outside material is thermally isolated from the load carrying member and the inside material. The load carrying member is conveniently steel.

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.
