Multifunctional rotating panels on a suspended supporting structure composed of: - two rotating panels having a lengthways cut whose thickness (X, S) decreases gradually to allow for suspension and with a circular cut at the base to allow for rotation; - a suspended supporting structure with a triangular section cutting with the vertex pointing downwards and with a base having the width and length (l) directly proportional to these rotating panels according to the equation Sb:L=X:S; by which X = (Sb x S)/L, wherein Sb is the length of the overhang part of the rotating panels overhanging from the suspending supporting structure, L is the width of the panels and of the base of the supporting structure, X is the thickness at the origin of the panels and S is the final thickness of the panels, the supporting suspended structure having moreover a posterior inserted panel which has 3 anchorage holes for fixing to a fixed or mobile structure; - solid steel bearing with a cylindrical tube threaded at the tip and welded in the central part of the cap of the bearing which has in turn 4 holes located in central lodgings of the rotating panels, a closing plug of the solid steel bearing which has a hole positioned in the central part for the passage of the cylindrical tube and located on the base of the supporting suspended structure, a self-blocking bolt for the fixing of the rotating planes onto the base of the supporting suspended structure; which screws into the threading of the above mentioned cylindrical tube, and wherein by either tightening or loosening it the resistance to rotation of the panels either increases or decreases. - two rotating panels having a lengthways cut whose thickness (X, S) decreases gradually to allow for suspension and with a circular cut at the base to allow for rotation; - a suspended supporting structure with a triangular section cutting with the vertex pointing downwards and with a base having the width and length (l) directly proportional to these rotating panels according to the equation Sb:L=X:S; by which X = (Sb x S)/L, wherein Sb is the length of the overhang part of the rotating panels overhanging from the suspending supporting structure, L is the width of the panels and of the base of the supporting structure, X is the thickness at the origin of the panels and S is the final thickness of the panels, the supporting suspended structure having moreover a posterior inserted panel which has 3 anchorage holes for fixing to a fixed or mobile structure; - solid steel bearing with a cylindrical tube threaded at the tip and welded in the central part of the cap of the bearing which has in turn 4 holes located in central lodgings of the rotating panels, a closing plug of the solid steel bearing which has a hole positioned in the central part for the passage of the cylindrical tube and located on the base of the supporting suspended structure, a self-blocking bolt for the fixing of the rotating planes onto the base of the supporting suspended structure; which screws into the threading of the above mentioned cylindrical tube, and wherein by either tightening or loosening it the resistance to rotation of the panels either increases or decreases.
