In addition, the vacuum cleaner includes a control handle displaceable between operating and storage positions. A stabilizer on the handle is provided adjacent the floor in the storage position. Engagement of the stabilizer with the floor prevents the vacuum cleaner from inadvertently tipping over rearwardly.Type: GrantFiled: April 21, 2004Date of Patent: September 13, 2005Assignee: Panasonic Corporation of North AmericaInventors: Michael J. Shanor, Amy N. Mudd

Patent number: 6920665Abstract: The invention is a floor care appliance such as vacuum cleaner having a pivoting valve arrangement for maintaining suction from the appliance housing to the suction nozzle. A valve is provided for sealing off suction to the suction nozzle when the housing is in the upright or off the floor mode position. When the housing is in the upright position maximum suction is directed to the accessory hose. When the housing is moved to the floor mode maximum the valve is moved to the open position and suction is directed to the suction nozzle for floor cleaning. The valve is located in a valve body assembly pivotally connected over the rear duct of the suction nozzle. The valve body is partially located in the housing and pivots with the housing. A roller and cam arrangement cause the valve located in the valve body to move back and forth between the open and closed positions.Type: GrantFiled: September 30, 2002Date of Patent: July 26, 2005Assignee: The Hoover CompanyInventor: Richard R. Tucker

Patent number: 6886215Abstract: An apparatus for use with a vacuum cleaner filter bag comprises a vacuum cleaner fill tube. The fill tube is configured for the bag to be mounted on the fill tube. The fill tube has an outlet through which a working flow of vacuum cleaner air can exit the fill tube to enter the bag when the bag is mounted on the fill tube. Additionally, the apparatus comprises a valve shiftable into and out of a closed condition in which the valve blocks the air from exiting the fill tube through the outlet.Type: GrantFiled: April 29, 2002Date of Patent: May 3, 2005Assignee: The Scott Fetzer CompanyInventors: Diane L. Dodson, Philip G. Hays, Robert L. Petrosky, Phillip E. Bearden

Patent number: 6880201Abstract: A vacuum cleaner having a main body and a handle, the main body being formed with a nozzle which delivers a stream of dirt-laden air through a dirt duct through a motor-fan inlet, the handle being supported on the motor-fan assembly and housing a filter bag which communicates with the motor-fan assembly for receiving the dirt-laden air, the motor-fan assembly having a motor housing, a motor with commutated brushes which give off carbon dust particles, a motor cooling fan for drawing a cooling airstream and a working fan for drawing the dirt-laden air, the vacuum comprising: an opening formed in the motor housing for receiving the cooling airstream; a cooling outlet formed in the motor housing through which the cooling airstream exists; means for directing the existing cooling airstream into the dirt-laden air; a collar extending axially outwardly from the motor housing, the collar allowing pivotal rotation of the motor housing relative to the main body.Type: GrantFiled: September 27, 2002Date of Patent: April 19, 2005Assignee: The Hoover CompanyInventor: William H. Theiss

Patent number: RE38842Abstract: For use with vacuum cleaner bags of the type having a substantially rigid collar surrounding the bag opening, and with vacuum cleaners of the type having a dirty air outlet nozzle, a vacuum bag docking assembly is shown and described. The assembly incorporates an anchor member having a central opening for closely receiving the dirty air outlet nozzle. The assembly also incorporates a mounting member which engages the collar on the vacuum bag to secure the bag to the bag mounting member. The bag mounting member is pivotally connected to the anchor member, and moves between a loading position in which the bag can be inserted or removed from the mounting member, and a working position in which the bag opening engages the dirty air outlet nozzle.Type: GrantFiled: February 27, 2002Date of Patent: October 25, 2005Assignee: Oreck Holdings, LLCInventors: William G. Fish, Charles F. Malone

Patent number: RE38998Abstract: An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. In one embodiment, the apparatus includes an intake body having an intake opening configured to receive the flow of air into particulates. An airflow propulsion device is coupled to the intake opening to draw the flow through the intake opening and through a flow passage having an approximately constant flow area. The flow continues through one or more conduits from the propulsion device to a filter element housed in a filter housing where the particulates are separated from the flow of air.Type: GrantFiled: January 23, 2004Date of Patent: March 7, 2006Assignee: Oreck Holdings, LLCInventors: Michael E. Embree, Terrance M. Roberts, James F. McCain
