Patent number: 8720002Abstract: A handle assembly for a cleaning appliance such as a vacuum cleaner includes a flexible hose having a first end that is connectable to a main body of the cleaning appliance and a second end, a handle portion for maneuvering the handle assembly during use and a tubular wand. The second end of the flexible hose is connected to the handle portion, and the tubular wand is slidably mounted in the handle portion so as to be movable between a first position in which the tubular wand extends beyond the handle portion inside the flexible hose and a second position in which the tubular wand extends beyond the handle portion away from the flexible hose.Type: GrantFiled: July 5, 2012Date of Patent: May 13, 2014Assignee: Dyson Technology LimitedInventors: Peter David Gammack, Andrew McCulloch, Benjamin John Strutt, Sarah Helen Liddell, William Robert James White

Patent number: 8707509Abstract: A surface treating appliance includes a surface treating head, a hose, and a fan unit for generating a flow of fluid. A flexible duct assembly has a first end and a second end moveable relative to the first end between a first position allowing fluid flow between the hose and the fan unit, and a second position allowing fluid flow between the surface treating head and the fan unit. The duct assembly is connected to a first support which is pivotable about a first axis, and to a second support which is pivotable about a second axis spaced from the first axis. A drive mechanism effects the pivoting movement of the supports about their axes to move the second end of the duct assembly between the first and second positions.Type: GrantFiled: March 9, 2012Date of Patent: April 29, 2014Assignee: Dyson Technology LimitedInventors: William Robert James White, James White, Adam William Rollo, David Christopher James Newton, Christopher Thomas Watson

Patent number: 8156609Abstract: A handheld cleaning appliance includes a dirty air inlet, a clean air outlet and separating apparatus for separating dirt and dust from an airflow in an airflow path leading from the air inlet to the air outlet. The separating apparatus includes a cyclonic separator having at least one cyclone and a collector having a wall and a base member, the base member being held in a closed position by a catch and being pivotably connected to the wall. The appliance further includes a main body which incorporates an actuator for operating the catch. The actuator has a slidably mounted rod which is movable between an inoperative position and an actuating position in which the rod contacts part of the catch so as to allow the collector to be opened for emptying purposes. This arrangement allows the catch to be released without the user actually touching the collector.Type: GrantFiled: July 6, 2007Date of Patent: April 17, 2012Assignee: Dyson Technology LimitedInventors: William Frame Milne, William Robert James White

Patent number: 8117712Abstract: A handheld cleaning appliance includes a dirty air inlet, a clean air outlet and separating apparatus for separating dirt and dust from an airflow in an airflow path leading from the air inlet to the air outlet. The appliance also includes a body housing a fan and motor for drawing air into the appliance via the dirty air inlet. The separator includes at least one cyclone. The separator and the body are releasably connected together around a chamber in the airflow path which is formed partly by the body and partly by the separator, the chamber housing a filter which is located upstream of the fan and motor and downstream of the cyclone.Type: GrantFiled: July 6, 2007Date of Patent: February 21, 2012Assignee: Dyson Technology LimitedInventors: James Dyson, William Robert James White, William Frame Milne

Patent number: 8042224Abstract: A cleaning appliance includes a main body, a handle assembly and a hose. The handle assembly includes a tube and a gripping portion fixedly attached thereto. The hose has one end attached to the main body. The tube is movable relative to the main body between a stored position in which at least a part of the tube lies within the hose and an extended position in which the gripping portion can be used to manipulate the cleaning appliance in use. By providing such an arrangement, the handle assembly and the hose can be stored compactly. When the user wishes to store the cleaning appliance, the tube can be retracted inside the hose for storage. When the tube is extended, the gripping portion is at a convenient height to be manipulated by a user.Type: GrantFiled: August 1, 2008Date of Patent: October 25, 2011Assignee: Dyson Technology LimitedInventors: William Robert James White, Tom Vallance Hamilton Crawford

Patent number: 7823251Abstract: A surface-treating appliance in the form of a vacuum cleaner has a main body, a surface-treating head and a support assembly. The support assembly is moveable between a supporting position, in which it supports the main body, and a stored position, in which it lies substantially against the main body. The provision of a support assembly that lies substantially against the main body of the appliance when not needed improves the maneuverability and range of motion achievable by the appliance in use. The support assembly may be brought out of its supporting position by a user-depressible pedal, which makes the appliance user-friendly.Type: GrantFiled: January 13, 2006Date of Patent: November 2, 2010Assignee: Dyson Technology LimitedInventors: James Dyson, Stephen Benjamin Courtney, Peter David Gammack, William Robert James White

Publication number: 20090188067Abstract: An attachment for a cleaning appliance includes a head including a suction opening and a neck including an intermediate portion and an end portion for connection to the mouth of a wand or hose having a longitudinal axis. The attachment also includes a first rotatable connection located between the end portion and the intermediate portion having a first axis of rotation and a second rotatable connection located between the head and the intermediate portion having a second axis of rotation. Each rotatable connection allows relative movement of the end portion with respect to the head. The first axis of rotation is inclined with respect to the longitudinal axis of the end portion. By providing such an attachment for a cleaning appliance, the head of the attachment can be moved into a variety of useful positions to allow easier cleaning of walls and high-level horizontal surfaces.Type: ApplicationFiled: March 1, 2007Publication date: July 30, 2009Applicant: Dyson Technology LimitedInventors: William Robert James White, Adam Andrew Wishney
