Roller shutter has door sheet closure pressurized by clamping element and held in such way that collision of door sheet closure with obstacle causes bending straight door leaf closure

摘要

The shutter has flexible door sheet closure has multiple form-stable segments (8) arranged along the lower edge of the door sheet (2) in rows and lying at front surfaces, which are subjected by a tensioning element in such away that they are held together. The collision of the door sheet closure (6) with a obstacle causes a distortion of the otherwise straight running door sheet closure. The door sheet closure is pressurized by a clamping element (9) and held in such way that the collision of the door sheet closure with a obstacle (7) causes a bending straight door leaf closure.
