| 摘要 |
The present invention provides a sliding door structure comprising at least a first and a second upper guide and a first and a second lower guide, said guides being elongated and parallel to and spaced from one another; at least a first and a second door each extending along one of a pair of planes and having an upper and a lower edge region; means for supporting said first and second doors, respectively, on said first and second upper guides for sliding movement longitudinally thereof and parallel to said planes, and said first door also for transverse displacement relative to said planes, between a closed position in which said first door is substantially coplanar with said second door and a plurality of open positions in which said first door is superimposed with said second door, including first and second upper rollers, respectively engaging said first and second upper guides for said movement along the same, and means for rotatably mounting said first and second upper rollers on said upper edge regions, respectively of said first and second door, including an upper linking mechanism which mounts said first upper rollers on said upper edge region of said first door for said transverse displacement of said first door relative to said first upper rollers at said closed position; and means for guiding said lower edge regions of said first and second doors respectively on said first and second lower guides for said movement longitudinally thereof and for said transverse displacement of said first door at said closed position, including first and second lower rollers respectively engaging said first and second lower guides for said movement along the same, and means for rotatably mounting said first and second lower rollers on said lower edge regions respectively of said first and second door, including a lower linking mechanism which mounts said first lower rollers on said lower edge region of said first door for said transverse displacement of said first door relative to said first lower rollers at said closed position and includes an elongated lower bracket having an upright flange affixed to said lower edge region of said first door and a substantially horizontal flange, at least two slides secured to said horizontal flange at locations which are spaced from one another longitudinally of said lower bracket, at least two guiding members each engaging one of said slides and carrying one of said first lower rollers, at least two cranked lower thrust elements each having an elbow portion pivoted on one of said guiding members and two arms one of which is slidably connected to said horizontal flange of said lower bracket, a lower thrust element displacement rod pivotally connected to the other of said two arms of each of said lower thrust elements, and a thrust roller rotatably mounted on said second door and engaging said lower thrust element displacement rod. |
