Lifting or folding door is in locked sections when closed which separate at the deflections while being wound for raising or folded together on a side movement to reduce space for the door structure when opened

摘要

The sectioned door, which is opened by rolling and lifting upwards or folding to the sides, has neighboring sections (1,1a) which are separated from each other on being deflected around a winding roller or when folded together. When the door is deployed in the closed position, the door sections (1,1a) are locked together along their longitudinal edges by complementary grips (7,7a).
