ABSTRACT:
A mounting bracket for a ceiling fan blade is cut into two separate pieces that are pivotally interconnected to one another so that the blade is pivotal in either of two directions about the pin. A lock ring is positioned radially outwardly of the pivot point to lock the blade into its operable position. Rotation of the lock ring until a slot formed in the lock ring is in alignment with the mounting bracket neck frees the mounting bracket to pivot downwardly, facilitating cleaning of the blade. In a second embodiment, a mounting bracket releasably couples together inward and outward parts of the mounting bracket so that the fan blade is completely detachable from the motor assembly to facilitate cleaning of the blade. In a third embodiment, a bag having cleaning pads at its mouth is used to clean either the pivotally mounted blade or the releasably coupled blade.
