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
