Suspended sliding door with lowered sealed position - has T-section support beam forming roller track and seal seat

摘要

Sealing strips locating between the door and frame components are raised from their seats as the door leaves are lifted from their closed positions to their sliding positions so that the seals are not abraded by the sliding motion. The door has two parallel sliding and overlapping leaves. The overhead support frame beam has a T section with a hollow leg locating between leaves, returned flanges on the leg forming roller guide tracks and an inverted Y downward leg and arm extension forming seal surfaces. Rounded upper flange extremities of the beam support pivotable fascia boards. The roller guide tracks have lower openings receiving the rollers in the door closed positions.
