Roll door unit, roll-up door and use of a roll door unit for covering a door opening

Abstract

The invention relates to a roll door unit (1 1) for covering a door opening, a roll-up door (IO) comprising this roll door unit and a specific use of the roll door unit (IO). The roll door unit (11) comprises a flexible door panel (16), a rotatable roll shaft (15) for rolling-up the flexible door panel (16), side frames (12), mounting flanges (14) for mounting the roll shaft (15) to the side frames (12), a connecting element (17) for connecting a motor unit (18) to the roll shaft (15), and supporting beams (13) for supporting the side frames (12) in mounted state and being connected or connectable to a wall or ground, whereby a longitudinal axis of the roll shaft (15) is positioned in alignment with a plane being spanned by the supporting beams (13). The technical solution described is characterized in that, the support beams (13) and the mounting flanges (14) are arranged at a distance from one another in such a way, that in mounted state forces exerted by the roll shaft (15) are introduced into the supporting beams (13) indirectly through the side frames (12).
