Claim of US Patent No. 10,660,235

12. A method for a fan, the method comprising:causing a spindle of the fan, situated within a duct, to rotate, thereby causing one or more blades extending radially from the spindle to automatically pivot about a radial axis from a closed position restricting airflow through the duct to an axially displaced open position drawing air through the duct;
automatically returning the one or more blades to the closed position when the spindle ceases rotating;
providing a driver concentrically located within the spindle, such that the spindle rotates around the driver, the driver comprising one or more actuation arms, wherein rotation of the driver causes each actuation arm to radially displace a lever coupled to each fan blade from a first position to a radially displaced second position to cause the each fan blade to pivot about the radial axis from the closed position restricting airflow through the duct to the axially displaced open position drawing air through the duct.
