Patent number: 9247853Abstract: An upright vacuum cleaning appliance includes a main body having a user operable handle, separating apparatus for separating dirt from a dirt-bearing air flow and a casing housing a fan unit for drawing the air flow through the separating apparatus. A support assembly is connected to the main body for allowing the appliance to be rolled along a surface using the handle. The support assembly includes a pair of domed-shaped wheels which each have a substantially circular rim. The overall size of the appliance is reduced by locating the casing between the wheels, and providing an air duct which extends between the rims of the wheels to convey the air flow from the separating apparatus to the casing.Type: GrantFiled: January 27, 2014Date of Patent: February 2, 2016Assignee: Dyson Technology LimitedInventors: James Dyson, Peter David Gammack, Stephen Benjamin Courtney, David Christopher James Newton, Michael Sean Joynt, Samuel James Czerpak

Patent number: 9044129Abstract: A surface treating appliance includes a surface treating head, a hose, and a main body including a fan unit for generating a flow of fluid, and a rotary changeover valve including a valve member which is selectively rotatable 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 valve member comprising a hub having an internal surface shaped to receive a boss about which the valve member is selectively rotatable. To facilitate the breaking of seals by valve member and other parts of the appliance as the valve member moves away from one of its first and second positions, the external surface of the boss and the internal surface of the hub each has a profile generally in the form of a triangular prism, the profile of the external surface of the boss tapering towards the valve member.Type: GrantFiled: October 8, 2010Date of Patent: June 2, 2015Assignee: Dyson Technology LimitedInventors: Paul Andrew McLuckie, William David Postle, Samuel James Czerpak, Christopher Thomas Watson, Leigh Michael Ryan

Patent number: 9009913Abstract: An upright surface treating appliance includes a main body, a surface treating head connected to a yoke, and a stand. To provide a compact appliance the yoke and the stand are pivotable independently relative to the main body about a common pivot axis. This can also enable the yoke and the stand to be rotatably connected to the main body using one or more common connectors or bearings.Type: GrantFiled: October 12, 2010Date of Patent: April 21, 2015Assignee: Dyson Technology LimitedInventors: Andrew James Wills, Matthew William Ford, James Dyson, Peter David Gammack, Stephen Benjamin Courtney, Samuel James Czerpak, Michael Sean Joynt, Adam William Rollo, James White

Patent number: 8793836Abstract: A surface treating appliance includes a surface treating head, a hose and a main body including a fan unit for generating a flow of fluid and a rotary changeover valve. The changeover valve includes a valve body having a first section for receiving fluid flow from the surface treating head, a second section for receiving fluid flow from the hose, and third section for conveying fluid flow towards the fan unit; and a valve member which is selectively moveable between a first position which connects the second section to the third section, and a second position which connects the first section to the third section. To minimize the number of components of the main body, the valve body forms part of a casing for the fan unit.Type: GrantFiled: October 11, 2010Date of Patent: August 5, 2014Assignee: Dyson Technology LimitedInventors: William David Postle, Samuel James Czerpak, Christopher Thomas Watson, Leigh Michael Ryan

Patent number: 8650708Abstract: An upright surface treating appliance includes a main body having a user operable handle, and a support assembly for allowing the appliance to be rolled along a surface using the handle. The support assembly includes a yoke pivotably connected to the main body, and a pair of domed-shaped wheels rotatably connected to the yoke. A surface treating head is connected to the yoke. The yoke is shaped so that a section of the yoke is located between the rims of the wheels. To afford a compact appearance to the appliance, the outer surfaces of the wheels and the section of the yoke together at least partially delimit a substantially spherical volume.Type: GrantFiled: October 8, 2010Date of Patent: February 18, 2014Assignee: Dyson Technology LimitedInventors: James Dyson, Peter David Gammack, Stephen Benjamin Courtney, David Christopher James Newton, Samuel James Czerpak, Michael Sean Joynt
