摘要

The cord geometric device for a cord network comprises a support mast (1) with a top central point (3) from which stem wire cords (2). There is, between the wire cord and the support mast, at least one cord spread (4). The cord spread may have a spread rod (5) fixable to the support mast and the wire cords. The spread rod may have a slidable cord fixture (6) on the cord harness side, whilst the support mast side may have a rotary point (10) with a spread rod holder (11). The spread rod holder may be slidably fixed to the support mast. The spread rod may be extended or shortened in the axial direction.
