ABSTRACT:
A cord winder apparatus for a vacuum cleaner system. The apparatus generally comprises a generally circular spool upon which a power cord is wound, and a generally circular race over which the spool is coaxially disposed to enable the spool to be rotated thereon as the power cord is unwound and rewound on the spool. The race and spool are further positioned coaxially over a portion of a motor of the vacuum cleaner system to maintain a compact profile of the system. A coil spring is further coupled to the spool to provide a constant retracting force to rotate the spool in a retract direction to rewind the power cord once it has been at least partially unwound from the spool. A brake is further included for releasably maintaining the spool in a desired position once the power cord has been unwound from the spool a desired amount. Power is coupled from the power cord via a pair of continuous conductive strips disposed on an interior wall of the spool and a pair of conductive contacts disposed on a vertical outer sidewall of the race. The contacts are in turn coupled to a motor of the assembly. An optional cord retaining member may be included to facilitate maintaining the power cord upon the spool when the cord is at least partially wound upon the spool.
