ABSTRACT:
A method and apparatus are provided for mounting fan blades to a ceiling fan with a mounting bracket and support arms which support each of the fan blades at two separate points. The mounting bracket is mounted to a motor for the ceiling fan and rotates in response to powering the motor. The fan blades are each secured to the mounting bracket at first points. The support arms have inward portions which are rigidly secured to the mounting bracket. The support arms extend from beneath the fan blades in a spaced apart relation with the fan blades. The support arms extend outward from a central axis for the ceiling fan to second support points on the lower sides of the ceiling fan blades. The second support points are disposed outward from the mounting brackets for reinforcing mounting of the fan blades to the motor. In a preferred embodiment, the mounting bracket includes decorative medallions for fitting beneath the fan blades to secure the fan blades and the support arms to the mounting bracket, and the support arms have decorative scrolled portions which extend beyond the decorative medallions.
