Abstract
A rolling support assembly having a carrier with a housing configured for lateral reception within a corresponding cavity in a sliding door for frictional reception therein in a manner precluding longitudinal movement out of the cavity. The carrier mounts and provides for vertical adjustment of a depending wheel set offset to underlie the center of weight of the door and engage a pair of wheel rails provided on an underlying track including rail protecting overlying flanges and/or members.
Claims18
A rolling support assembly for a sliding door wherein said door is of a predetermined thickness between opposed first and second faces and has peripheral edges including a lower edge, an upper edge, a leading edge and a following edge;
- a cavity defined in said door adjacent said lower edge and inward through said first face thereof to a depth less than the thickness of said door, said cavity terminating in an inner wall and having a restricted open lower end at said lower edge of said door, said cavity, at approximately mid-height upward from said lower end having a laterally restricted central portion defining upper and lower cavity sections laterally enlarged relative to said restricted central portion and said restricted lower open end, a carrier including a housing of a configuration conforming to that of said cavity and including upper and lower housing portions conforming to and receivable within said cavity sections, said housing further including a restricted intermediate area receivable within said restricted central portion of said cavity, said housing being receivable within said cavity solely through said first face of said door, said housing being precluded from longitudinal movement in said cavity and frictionally retained therein in a manner resisting free withdrawal laterally through said first face of said door for temporary retention of said carrier as an assist to positioning and fixedly mounting said carrier, said carrier further including a face plate rigid with said housing and receivable over said first face of said door upon engagement of said housing within said cavity, fastener means engageable through said face plate and into said door for a fixed mounting of said carrier, and a wheel set mounted on and vertically adjustable relative to said carrier and below said lower edge of said door.
A rolling support assembly for a sliding door, said support assembly including a carrier, a wheel set adjustably mounted to said carrier, and a track receiving and guiding said wheel set, said carrier being adapted for mounting to a lower edge portion of a door, said carrier including a housing with a face plate, said face plate having a lower edge, a recess defined in said face plate and opening through said lower edge, said wheel set including an adjusting stem longitudinally received and longitudinally adjustable within said recess, said stem projecting longitudinally beyond said recess and, below said face plate, being laterally offset and terminating in a lower linear extent paralleling said face plate, adjustment means for varying the vertical position of said stem and fixing said stem in selected vertically adjusted positions, said lower extent of said stem mounting a transverse axle with a pair of wheels mounted thereon, one to each side of said stem, said track including a pair of laterally spaced parallel wheel rails for receiving and guiding said wheels therealong, a second pair of wheel rails laterally spaced from and parallel to said first pair of wheel rails, an elongate support rail parallel to and centrally between said pairs of wheel rails, and a dust guard removably mounted to said support rail and extending vertically and laterally therefrom over an adjacent wheel rail of each pair of wheel rails at a height sufficient to accommodate a wheel therebelow.
A support and guiding assembly for a sliding door, said assembly including a lower track including a base panel, two pairs of wheel rails parallel to each other and extending upward from said base panel longitudinally therealong, a central support rail on said base panel centrally between said pairs of wheel rails and extending parallel thereto, a dust guard extending along the length of said support rail and releasably fixed thereto, said dust guard extending vertically above said wheel rails and in laterally overlying relation to an adjacent wheel rail of each pair of wheel rails in vertically spaced relation thereabove and defining a protective cover for these adjacent wheel rails.
