Support flange for the winding roll of a roller shutter

摘要

The flange (7) has a section (11) present at lower part of the flange and intended to engage and disengage a drive shaft (13) which connects a drive mechanism (9) e.g. driving pulley, disposed on a side of the flange, and a drive tube extending along opposite side of the flange. A reception unit of a bearing block is disposed on one side of the flange through an axial joint (17) of the bearing block. An independent claim is also included for a roller blind comprising a support flange.
