Folding shutter arrangement

摘要

A folding shutter arrangement having three or more rigid folding shutter elements having element edges that bend out and element edges that do not bend out in alternation. A first folding shutter element can be fastened to a building so as to be pivotable about a first axis near a element edge that does not bend out. A second folding shutter element is pivotably retained about a second axis near a second element edge that does not bend out. Adjacent folding shutter elements are pivotably connected to each other in pairs at the third element edges by a bend-out joint. A driving element is provided which drives at least one of the element edges in the opening or closing direction, and which forcibly pivots the folding shutter elements connected to at least one of the element edges that do not bend out.

1. A folding shutter arrangement that is movable between an open and closed position, said folding shutter arrangement including a first rigid folding shutter element, an intermediate rigid folding shutter element, and an end rigid folding shutter element, each of said rigid folding shutter elements having a first folding edge and a second folding edge,
said first rigid folding shutter element pivotally fastened at said first folding edge by a first joint or hinge to a fixed structure such that said first rigid folding shutter element only pivots relative to the fixed structure, said second folding edge of said first rigid folding shutter element pivotally connected to said first folding edge of one of said intermediate rigid folding shutter element by second joint or hinge, said second folding edge of one of said intermediate rigid folding shutter element connected to a guide carriage arrangement by a third joint or hinge, said guide carriage arrangement movably connected to a first guide and movable along a longitudinal length of said first guide, said guide carriage arrangement positioned closest to said first joint or hinge when said folding shutter arrangement is in said open position, said first folding edge of said end rigid folding shutter element pivotally connected to said guide carriage arrangement by a fourth joint or hinge, said second folding edge of said intermediate rigid folding shutter element and said first folding edge of said end rigid folding shutter element are independently pivotally connected to said guide carriage arrangement, said first folding edge of said end rigid folding shutter element is pivotally connected to said guide carriage arrangement such that when said guide carriage arrangement moves toward the fixed structure said second folding edge of said end rigid folding shutter element is caused to pivot toward the fixed structure, said first folding edge of said end rigid folding shutter element is pivotally connected to said guide carriage arrangement such that when said guide carriage arrangement moves away from the fixed structure said second folding edge of said end rigid folding shutter element is caused to pivot away from the fixed structure.
