Sectional door

摘要

The sectional door has a number of interlinked and hinged panel units (1) riding on rollers (22) in guide rails (6) forming the inner and outer sides of the door. The door panels are fitted with openings (42) at the edges to take the recessed roller axes and give a shrouding for the guide rails by the lip structure of the edges of the door panels, to give a smooth inner door surface down to the floor and up to the ceiling or at the sides in rolling door. The panels are linked by inner hinges or upper hinge hooks.
