Patent number: 6626969Abstract: An apparatus for mounting a vacuum cleaner filter bag on a vacuum cleaner fill tube includes a filter bag panel. The panel is configured to be grasped by a hand to mount the bag on the fill tube. The panel has an inner edge defining an opening for receiving the fill tube when the bag is mounted on the fill tube. The panel further has an outer edge. A first recessed section of the outer edge is sized and shaped to receive a single finger of the hand when the hand grasps the panel. The first recessed section has a first innermost location. A second recessed section of the outer edge is sized and shaped to receive the thumb of the hand when the hand grasps the panel. The second recessed section has a second innermost location. The innermost locations are spaced apart from each other along an imaginary straight line extending across the opening.Type: GrantFiled: April 2, 2002Date of Patent: September 30, 2003Assignee: The Scott Fetzer CompanyInventor: Daniel L.

Publication number: 20020020155Abstract: A holding plate for the filter bag of a vacuum cleaner has a plug-in opening for attaching a pipe socket of the vacuum cleaner. A seal for sealing the holding plate against the pipe socket of the vacuum cleaner projects into the plug-in opening. In order to lock the holding plate on the pipe socket of the vacuum cleaner, at least one projection pressing the seal against the pipe socket of the vacuum cleaner and projecting into the plug-in opening is provided on the holding plate. In this way, the holding plate is retained on the pipe socket of the vacuum cleaner in a clamped seat.Type: ApplicationFiled: March 20, 2001Publication date: February 21, 2002Inventor: Arnoldus Stokmans

Patent number: 6277164Abstract: An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. The apparatus can include a manifold with two inlet ports that collect two separate streams of the flow, combine the streams, and direct the combined flow toward a filter element through a single outlet port. The flow can expand within the manifold between the inlet ports and the outlet ports to decelerate the flow. The manifold can also include a storage receptacle for storing a belt used to drive a roller brush of the vacuum cleaner.Type: GrantFiled: April 6, 1999Date of Patent: August 21, 2001Assignee: Oreck Holdings, LLCInventors: Michael E. Embree, Terrance M. Roberts, James F. McCain

Patent number: 6277163Abstract: An apparatus and method for housing a filter element of a vacuum cleaner. In one embodiment, the apparatus can include a housing body elongated along a housing axis. The housing body can include a partially porous material clamped at an upper end to an upper Support and at a lower end to a lower support. The upper and lower supports support the upper housing body relative to the vacuum cleaner. The housing body further includes an aperture for receiving a filter element and can have a generally constant cross-sectional area when intersected by a plane approximately perpendicular to the housing axis.Type: GrantFiled: April 6, 1999Date of Patent: August 21, 2001Assignee: Oreck Holdings LLCInventors: Michael E. Embree, Terrance M. Roberts, James F. McCain
