Abstract
A ceiling fan is provided and includes articulated fan blades such that when the fan is off the blades will hang vertically downwardly by force of gravity and when the fan is turned on the blades will rise radially to a horizontal pitched angled position due to the coaction of centrifugal force, and wind reaction force.
Claims3
A ceiling fan-lamp which comprises:
- (a) a hanger suspended from a ceiling;
- (b) an electric driving motor mounted to said hanger;
- (c) a hub attached coaxially to said motor and rotatively driven by said motor;
- (d) a plurality of angularly pitched hinge brackets, arcuately spaced apart and attached to said hub each hinge lying substantially tangential to said hub with one end of the hinge being raised in a horizontal plane above the other end of the hinge,
- (e) a plurality of longitudinal fan blades, each connected at one end to a respective hinge bracket wherein the hinge is connected to the blade along a line which is angularly positioned with respect to a longitudinal axis of the blade, whereby said hinge bracket will permit free rotation of said fan blade from a relatively vertical unpitched position to a relatively horizontal running pitched position, and counter balance plates connected to the blades adjacent to the hinge brackets.
