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.
Claims8
Suspension system and sliding panel assembly comprising at least one vertically positioned sliding panel, said sliding panel having an upper frame and a bottom, a bearing assembly connected to said upper frame of said sliding panel, a bottom guide for said sliding panel connected to said bottom of said sliding panel, said bearing assembly including at least two sets of bearings, each of said sets of bearings comprising a pair of wheels mounted perpedicularly to the plane of said panel and each of said wheels being operable to move in a respective concave track, a hanger connected and centrally hung between each of said pair of wheels, said hanger running parallel to the plane of said sliding panel a distance at least substantially as long as the length between said sets of bearings, said hanger being received within a wedge, said wedge extending for a distance at least as long as said hanger, said wedge being operably mounted between said panel and said bearing assembly, either of said wedge or said bearing assembly being movable relative to the other of said wedge and bearing assembly with said other of said wedge or hanger being stationary relative to said panel and being operably attached to said panel, said sliding panel being hung from said hanger such that the weight of said panel acts principally through said hanger and applies substantially equal loading to each of said pair of wheels, said wheels having rounded convex circumferences which are complementary to and which run within said concave track.
A sliding panel and bearing assembly for installation within an upper bracket of a panel frame and a lower drain tube of said panel frame, said sliding panel having a top and a bottom, said sliding panel and bearing assembly comprising an upper bearing connected to said top of said sliding panel and movable within said upper bracket and a lower guide member on said bottom of said panel which guide member is movable within said lower drain tube, said upper bearing comprising at least two sets of bearings, each of said sets of bearings including a pair of rotatable wheels, each of said wheels having a convex circumference which convex circumference is complementary to and moves within respective concave guide paths located on opposite sides of and within said upper bracket and a hanger extending downwardly from said sets of bearings and between said pair of rotatable wheels, said hanger extending on the top of said panel a length at least substantially as long as the distance between said sets of bearings, said panel having a weight which acts principally downwardly through said hanger and which exerts substantially identical forces on each of said wheels on opposite sides of said hanger, a wedge member operably installed between said bearing assembly and said sliding panel, said wedge member being movable relative to one of said bearing assembly and said sliding panel, the other of said bearing assembly and said sliding panel being stationary relative to said wedge member and being operably attached to said panel, said hanger of said bearing assembly being received in said wedge member, said wedge member extending at least as long as said hanger.
