Patent ID: 7192252

Claim:
Wind turbine comprising a mast ( 2 ) articulated so as to take a straightened position in which the mast extends substantially vertically above a foundation anchored to the ground and a folded position close to the ground, and a rotor ( 4 ) equipped with blades ( 5 to 7 ) installed in a vicinity of a top of the mast so as to rotate about a substantially horizontal axis (A) when the mast is in the straightened position, characterized in that the mast comprises at least two mobile segments ( 13 , 15 ) articulated about axes ( 12 , 14 ) which are substantially horizontal and parallel to one another, so as to pivot in a given direction from the straightened position, said pivoting direction being reversed between successive articulations, the mobile segments ( 13 , 15 ) extending substantially horizontally in the folded position, and in that means ( 23 to 26 ) are provided for coordinating the pivoting of the different segments in such a way that the centre of gravity of the wind turbine remains substantially in vertical alignment with the foundation.
