Shutter systems

A method of operation of a shutter system comprising:

• a first leaf to be hingedly connected to a building structure, the first leaf being hingedly connected to a second leaf;
• a driving hinge mechanism comprising a tubular body longitudinally arranged between the first and second leaves, the first and second leaves being rotatably displaceable relative to each other about a longitudinal axis of the tubular body, defining at least a folded position and an expanded position of the first and second leaves;
• the first and second leaves each having a cross-sectional outline each cross-sectional outline having a beveled edge, the beveled edges of each cross-sectional outline of each of the first and second leaves being arranged to define a cavity for housing at least partially a tubular body cross-sectional outline of the tubular body;
• the tubular body comprising an actuating module operatively connected to a transmission module, the actuating module and the transmission module being rotatably displaceable relative to each other about the longitudinal axis, and each of the actuating module and the transmission module being respectively joined to the first and second leaves;
• the method comprising:
• activating the driving hinge mechanism under predefined parameters, the parameters being at least one of:
• angular speed, duration, angular direction, and/or angular span.

A folding shutter system comprising:

• a first leaf to be hingedly connected to a building structure, the first leaf being hingedly connected to a second leaf;
• a driving hinge mechanism comprising a tubular body longitudinally arranged between the first and second leaves, the first and second leaves being rotatably displaceable relative to each other about a longitudinal axis of the tubular body, defining at least a folded position and an expanded position of the first and second leaves;
• the first and second leaves each having a cross-sectional outline each cross-sectional outline having a beveled edge, the beveled edges of each cross-sectional outline of each of the first and second leaves being arranged to define a cavity for housing at least partially a tubular body cross-sectional outline of the tubular body;
• the tubular body comprising an actuating module operatively connected to a transmission module, the actuating module and the transmission module being rotatably displaceable relative to each other about the longitudinal axis, and each of the actuating module and the transmission module being respectively joined to the first and second leaves, the actuating module being detachably connected to at least one of the first and second leaves;
• the tubular body having the transmission module attached to one of the first and second leaves and a central portion of the tubular body attached to another of the first and second leaves, the central portion and the transmission module being rotatable relative to each other about the longitudinal axis.
