ABSTRACT:
An apparatus for connecting a downrod to a mounting assembly and a motor housing of a fan. The mounting assembly and the motor housing are capable of receiving a differently sized downrod. The apparatus comprises a pair of adapters. The adapters each have a first end that engages an end of the downrod; a second end that engages either the mounting assembly or the motor housing; and a hollow interior extending between said first and second ends. In one alternative embodiment, the first end receives the downrod and includes: a pair of aligned apertures; and an aperture disposed between the pair of aligned apertures. The second end is threaded and engages either the mounting assembly or the motor housing. The second end includes a pair of aligned apertures on opposite sides thereof. The apparatus also includes a pair of pins to insert through the aligned apertures and a pair of fasteners for securing the downrod within the adapter. In another alternative embodiment, the first end inserts within the downrod. The first end includes a pair of aligned apertures on opposite sides of the first end. The second end is threaded to engage either the mounting assembly or the motor housing. The second end includes: a pair of aligned apertures on opposite sides of the second end. The apparatus also includes a pair of pins for inserting through the aligned apertures to secure either the downrod or the motor housing to the adapter.
