Abstract
A ceiling fan including a motor having a rotatable rotor, a plurality of ceiling fans blades having a thickness, the blades connected to the rotor to rotate therewith and each of the ceiling fan blades comprising a thin edge along its leading edge that is thinner than the thickness of the ceiling fan blade to present less resistance and produce less turbulence and achieve high efficiencies.
Claims25
A ceiling fan comprising in combination:
- a motor having a rotatable rotor;
- a plurality of ceiling fan blades comprising two sides having a thickness therebetween, said blades being connected to said rotor to rotate therewith;
- each of said ceiling fan blades comprising a thin edge along its leading edge having an angled edge portion and a rounded edge portion, said rounded edge portion being thinner than said thickness of said ceiling fan blade to present less resistance and produce less turbulence and achieves high efficiencies;
- and
- a sheeting applied to at least one of said sides and to at least said angled edge portion.
A fan blade comprising a thin leading edge having an angled portion and a rounded portion, at least one surface of said fan blade comprising a sheeting that extends over said angled edge portion.
A method for manufacturing a fan blade having opposing surfaces and a thin edge comprising an angled edge portion and a rounded edge portion, comprising the step of applying a sheeting to at least one of said opposing surfaces to extend over at least said angled edge portion.
