Retractable roof with hinged folding panel structures suspended with cables

A retractable roof for a building having a supporting frame and a building structure extending vertically above the supporting frame, said retractable roof comprising:

• at least one structure section including first and second panel structures, said first panel structure having a first proximal end being hingeably mountable on the supporting frame at a proximal hinge and a first distal end hingeably connecting to a second proximal end of the second panel structure at a distal hinge, a second distal end of said second panel structure being suspended to the building structure with a distal end cable connected to a distal motorized winch;
• a tackle member connecting to both said first and second panel structures of said at least one structure section adjacent said first proximal end and said second distal end, respectively, and including a tackle wire forming a wire side of a triangular cross-sectional shape with said first and second panel structures;
• and
• a tackle winch connecting to the tackle member to control a wire length of the wire side.
