Patent number: 8567009Abstract: A suction nozzle assembly comprises a nozzle body with a slidably supported shuttling plate mounted therebeneath. The shuttling plate selectively directs suction to focused nozzle inlet openings at the front and rear portions of the nozzle body on forward and backward cleaning strokes, respectively. Converging debris paths defined by a plurality of debris guides direct debris towards the focused nozzle inlets. The debris guides further define along the underside of the shuttling plate sheet retention platforms that are isolated from the working air path and have dust cloths to remove dust from the surface.Type: GrantFiled: December 8, 2011Date of Patent: October 29, 2013Assignee: BISSELL Homecare, Inc.Inventor: Alan J. Krebs

Patent number: 8201303Abstract: A vacuum cleaner lint brush accessory system having a lint brush and cradle. The lint brush has longitudinally opposed handle and brush portions. The brush portion has a brush material adapted to remove fibrous substances from a surface to be cleaned. The cradle has a chamber opening leading to a chamber. The chamber extends in the longitudinal direction and is adapted to longitudinally receive at least the brush portion of the lint brush, the chamber has at least one brush cleaning pad adapted to engage the brush material and remove the fibrous substances from the brush material. The chamber further includes an air outlet spaced from the chamber opening. The air outlet is selectively connectable to a vacuum passage of a vacuum cleaner.Type: GrantFiled: March 12, 2010Date of Patent: June 19, 2012Assignee: Electrolux Home Care Products, Inc.Inventors: Robert R. Niederman, Thomas Josefsson, John C. Morphey, Brian Wang Sun

Patent number: 8122562Abstract: An surface cleaning implement comprises a recovery tank and a suction nozzle in fluid communication with a recovery tank, a fan/turbine assembly including a turbine-driven suction fan for generating suction at the suction nozzle, which draws liquid and air into and through the accessory tool. A fluid dispensing assembly is disclosed for storing and distributing fluid to the surface to the cleaned. An agitator assembly can be moved from a use to a non-use orientation to alternately scrub the surface to the cleaned and to extract fluid from the surface to be cleaned.Type: GrantFiled: December 19, 2008Date of Patent: February 28, 2012Assignee: BISSELL Homecare, Inc.Inventor: Alan J. Krebs

Patent number: 8042221Abstract: The present invention provides a board cleaning apparatus excellent in foreign-matter removing efficiency. Fixed brushes are each made in contact with a circuit board over an entire width thereof, and attached to a case of a board cleaning apparatus respectively on the upstream side and the downstream side of the case in the board transporting direction with respect to a rotary brush for removing and ejecting foreign matters. This arrangement makes it possible to cover a gap between the circuit board and the case to prevent a board transporting rail to be moved so as to be shifted in accordance with circuit boards having various dimensions from intervening with the case.Type: GrantFiled: July 17, 2006Date of Patent: October 25, 2011Assignee: Panasonic CorporationInventor: Yasuyuki Ishitani

Patent number: 7437797Abstract: The present invention relates to a duster brush assembly for a vacuum cleaner. The duster brush assembly includes a duster brush fixedly disposed at the air flow entrance of a hollow tubular member operatively connected to the vacuum cleaner. A hollow tubular member is telescopically mounted on a suction tube which is in communication with the vacuum cleaner. To clean the duster brush the hollow tubular member is moved forward over the duster brush is removed by vacuum into the vacuum cleaner.Type: GrantFiled: February 16, 2005Date of Patent: October 21, 2008Inventors: Patricia Kozlowski Ptak, Victor Alfred Ptak, Christopher Leo Ptak

Patent number: 6519810Abstract: A vacuum cleaner, performing a cleaning operation using a nozzle casing coupled to a suction pipe or using the suction pipe free from the nozzle casing, is disclosed. This vacuum cleaner does not force a user to change an existing cleaning tool with another tool even when it is desired to clean a limited or narrow area that does not allow use of the nozzle casing during the cleaning operation. In this vacuum cleaner, the suction nozzle unit consists of a nozzle casing provided with a suction nozzle for sucking dust-laden air from a surface into the casing. This casing also has a mounting unit provided with a fitting bore communicating with the suction nozzle. A hollow cylindrical suction pipe is removably fitted into the fitting bore, with a dusting brush part formed along the lower edge thereof. A spring-biased locking bolt removably locks the position of the suction pipe within the mounting unit of the nozzle casing.Type: GrantFiled: February 27, 2001Date of Patent: February 18, 2003Assignee: LG Electronics Inc.Inventor: Se-Hyun Kim

Patent number: 6266846Abstract: A vacuum cleaner head carries an array of brush bristles in conventional fashion. The bristles surround an inlet through which dust and debris are sucked into the vacuum cleaner during normal brushing action. A skirt is mounted inside the bristles so that when the head is pressed sufficiently towards a brushing surfaces a lower edge of the skirt can contact directly against the brushing surface.Type: GrantFiled: April 25, 2000Date of Patent: July 31, 2001Assignee: Talentone Development LimitedInventor: Ka Ming Chan
