摘要

The door which has a flexible plastics or fabric foil curtain (1) or slats has vertical side guide rails (3), support frame and drive unit. The curtain or slats each have at their side ends at least one wind catch which at the latest on reaching the substantially half-closed position of the door runs into locking hooks or locking claws (4) which are mounted in the corresponding region of the guide rails or support frame. The wind catches can be studs or noses integrated in the curtain to run into the hooks to prevent the curtain sliding out through the wind.
