Patent number: 8393052Abstract: An upright vacuum cleaner having dual cleaning motor and fan units is provided having a cleaning head engagable with a floor and a suction nozzle and a brush roller rotatably mounted therein. A first motor and fan unit is mounted in the vacuum cleaner for producing suction in the suction nozzle and is operatively connected to the brush roller for rotating it. An upright housing is connected to the cleaning head, the housing having a handle for moving the vacuum cleaner along the floor during floor cleaning use. Contained in the housing are a dirt storage container, a passageway leading from the suction nozzle in the cleaning head to the storage container and a second motor and fan unit operatively associated with the storage container for drawing dirt laden air from the cleaning head through the passageway and into the storage container simultaneously with operation of the first motor and fan unit.Type: GrantFiled: August 15, 2011Date of Patent: March 12, 2013Assignee: Tacony CorporationInventors: Douglas L.

Patent number: 6290422Abstract: A hook assembly for a vacuum cleaner handle which has a base member formed in the handle with a continuously internally walled extension defining an opening into which a continuously externally walled extension of a hook member can be inserted so that portions of the externally walled extension engage portions of the internally walled extension so that loads applied to the hook are transmitted to the handle through those surfaces. A spring normally biases the surfaces together, but can be manually overcome to rotate the hook for easy removal of the cord. A double hook arrangement is also provided to support a vacuum hose and an electrical cord with similar interengaging surfaces to transmit the load.Type: GrantFiled: August 4, 2000Date of Patent: September 18, 2001Assignee: Tacony CorporationInventors: David T. Hamm, John F. Kaido
