The present invention relates to a device for connecting a ceiling fan motor assembly to a downrod.
A downrod is generally used to hang a ceiling fan motor from a position overhead. In general, a first end of the downrod is mounted to a position on a ceiling, and the ceiling fan motor is attached to the second end of the downrod which hangs from the ceiling. Thus, the fan motor is suspended by the second end of the downrod.
Conventionally, the fan motor is attached to the downrod by a combination of screws and pins that lock the downrod into an insert assembly provided on a surface of the fan motor. More specifically, each of the downrod and the insert assembly on the fan motor in which the downrod will be inserted, are provided with corresponding holes which align when the second end of the downrod is positioned in the insert assembly in a predetermined manner. Accordingly, pins and screws can be inserted through the aligned holes of each of the downrod and the insert assembly in order to lock the fan motor onto the hanging downrod.
Other advantages and features of the invention will become more apparent with reference to the following detailed description of the presently preferred embodiment thereof in connection with the accompanying drawings, wherein like reference numbers have been applied to like elements, in which:
FIG. 1 illustrates a fan assembly according to the one embodiment of the invention;
FIG. 2 illustrates a connection assembly according to the present embodiment of the invention;
Turning to the drawings, a fan assembly 100 is illustrated in FIG. 1 according to one embodiment of the present invention. As shown, fan assembly 100 includes a connection assembly 101 provided on a motor assembly 102. Fan assembly 100 further includes, a fan blade 103, and a blade arm 104 for attaching fan blade 103 to motor assembly 102.
FIG. 2 illustrates the portions of connection assembly 101 in detail. In particular, FIG. 2 illustrates a downrod 201 and a connector 202, each of which will be described in detail hereinafter.
According to the present embodiment, connector 202 includes a flange 203, which extends upwardly, away from motor assembly 102. As shown, flange 203 defines the outer boundaries of an aperture 202a, which runs in a lengthwise direction from a surface 102a of motor assembly 102 upwardly through flange 203.
