The wind-brace (10) has blades (12, 44, 46) connected by levers (40, 42) articulated on inner, central and outer hinge points (24, 26, 28) of the blades, which are located in respective virtual planes. Geometric pivot axes (22) of the blades extend in longitudinal sides (18) of the blades while being shifted laterally relative to a defined thickness of the blades, when the blades are in open position. The inner and outer points are shifted laterally relative to center and diagonally opposed. The central point is located at the center relative to the thickness and defined width of the blades. |
