Abstract:
1. A ceiling fan comprising an electric motor that drives a plate, the plate supporting three or four equally spaced members positioned adjacent its periphery, each member connecting a blade with the plate and being secured to the plate to be pivotal thereto to provide limited arcuate movement, each member having a fan blade secured thereto, the arcuate movement of each member being confined from a retracted position where the blades are substantially within the periphery of the plate to an open position where the blades extend radially outwardly of the plate, each member being urged by resilient means into the refracted position, each member being directly joined to the adjacent member by a tie bar so that any movement of one member causes the same movement of the other members, and wherein adjacent tie bars overlap one another without contact as the blades move from the retracted to the open positions.
