Patent ID: 8790085

Claim:
A combined ceiling fan and light fitting having folding fan blades, the fan comprising: a blade support means arranged to be rotated by a motor about a fan rotation axis; a plurality of fan blades each having a root end tip; each blade being secured to the blade support means by being pivotally connected at its root end to the blade support means for rotation about an upright blade pivot axis so as to be moveable between a folded and an operative position, each blade being arranged to move from its folded position to its operative position by centrifugal forces when said motor rotates said blade support means; wherein the tips of said blades in their operating positions rotate in a plane which is higher than that in which the root ends of said blades rotate; each of the blades is cambered and are concave downward; and each blade has first gear means arranged to rotate with that blade; and the fitting has second gear means mounted so as to be rotatable coaxially relative to the electric motor and the blade support means and each first gear means meshes with the second gear means so that as the blades pivot between their folded and operative positions they are constrained to move in synchronisation with each other because of the meshing of the first and second gear means, wherein a biasing means acts between the blade support means and said sun gear second gear means.
