Support spoke for a windmill

摘要

A support spoke for a windmill for supporting blade rings of a windmill. The support spoke for a windmill includes an elongate rod with opposite first and second ends and a longitudinal axis extending between the ends. The first end is coupled to an outer ring of a fan portion of a windmill. The second end is adapted for threadable coupling to a hub of the fan portion of the windmill. An arm is rotatably coupled to the rod and is adapted for coupling to an inner ring of the fan portion of the windmill. A holding portion selectively prevents rotation of the arm about the rod to prevent loosening of the rod.
