Abstract
A ceiling fan (50) is disclosed having a motor housing (51) which encases an electric motor (53). The motor includes a bottom mounting plate (54) that rotates and thereby drives an annular array of blade irons (56), each having a blade (57) mounted thereto in conventional fashion. Each blade iron is mounted for pivotal and radial movement relative to the bottom mounting plate. An annular segmented balancing ring (68) made of a plurality of links (69) causes pivotal and radial movement of other blade irons (76) in response to the radial movement of an off-balanced blade iron.
Claims17
A fan comprising,
- an electric motor;
- a balancing member;
- an annular array of blade irons coupled to said motor for radial movement relative to said motor, each said blade iron also has an end pivotally mounted to said flexible balancing member;
- and
- a ceiling fan blade associated with each said blade iron of said annular array of blade irons,
- whereby the off balanced movement of a blade iron causes the radial movement of the flexible balancing member, which in turn causes the radial movement of the other blade irons towards an equilibrium position.
A ceiling fan comprising,
- an electric motor;
- an annular array of combined blade irons and blades coupled to said motor;
- a flexible balancing ring coupled to each said combined blade irons and blades, said balancing system pivotally moving select combined blade irons and blades in a direction generally away from the direction of movement of an off-set combined blade iron and blade,
- whereby an equilibrium balance is provided by the pivotal movements of the combined blade irons and blades.
A fan comprising,
- an electric motor;
- a balancing ring having a plurality of articulating links;
- an annular array of blade irons coupled to said motor, each said blade iron having a mounting member which allows pivotal and radial movement of said blade iron relative to said motor and a pivot member pivotally coupling said blade iron to said balancing ring;
- and
- a ceiling fan blade associated with each said blade iron of said annular array of blade irons,
- whereby the off balanced movement of a blade iron causes the radial movement of the balancing ring, which in turn causes the pivotal and radial movement of the other blade irons.
