Abstract
A sliding door system that includes at least one sliding door operable for movement between a closed position to at least partially cover a doorway opening and an opened position to at least partially expose the doorway opening. The sliding door has adjustable roller guides at each side of the sliding door that movably support the sliding door on a guide track along the floor.
Claims19
A sliding door system, comprising:
- a sliding door configured for mounting at a frame defining a doorway opening, the sliding door including:
- opposite first and second lateral sides extending in a longitudinal direction;
- and
- opposite first and second longitudinal sides extending in a lateral direction between the opposite first and second lateral sides;
- a guide track along the first longitudinal side;
- a first roller guide engaged to the sliding door adjacent the first lateral side and the first longitudinal side;
- and
- a second roller guide engaged to the sliding door adjacent the second lateral side and the first longitudinal side, wherein each of the first and second roller guides includes:
- a roller assembly movably engaged to the guide track, the roller assembly including a bracket, a roller rotatably mounted to the bracket, and a shaft extending from the bracket;
- and
- an adjustment assembly, wherein the shaft of the roller assembly is axially displaceable in the adjustment assembly, wherein the adjustment assembly is axially adjustable to set an allowable axial displacement of the shaft between a fully extended position and any one of a number of contracted positions within the adjustment assembly in order to adjust a height of the second longitudinal side of the sliding door above the guide track, wherein the adjustment assembly includes:
- a guide block engaged to the sliding door, the guide block including a passage movably receiving an end of the shaft opposite the bracket;
- and
- an adjuster engaged to the guide block, the adjuster being configured to advance axially into and out of the passage of the guide block to set an axial length of the passage that is available for allowable displacement of the shaft into the guide block in order to adjust the height of the sliding door from the guide track.
