Publication number: 20140041136Abstract: A cleaner head that includes an agitator and a drive assembly for driving the agitator. The drive assembly includes a dog for transmitting torque to the agitator. One of the dog and the agitator includes a shank having a screw thread, and the other of the dog and the agitator includes a bore having a complementary screw thread. The shank projects into the bore and the two threads mate such that, as the dog rotates, the agitator screws on to and tightens against the dog.Type: ApplicationFiled: August 9, 2013Publication date: February 13, 2014Applicant: DYSON TECHNOLOGY LIMITEDInventors: Will Henry KERR, Alistair William SKUSE

Patent number: 8544145Abstract: A surface treating head in the form of a floor tool for a vacuum cleaner includes a main body, a suction cavity and an outlet. The suction cavity includes first and second suction channels, bounded on both sides by respective working edges. A fluid flow path extends from the first suction channel to the second suction channel and from there to the outlet. The plurality of suction channels permits effective pick-up of dirt. To enable the surface treating head to be used to treat both carpeted floor surfaces and hard floor surfaces, the surface treating head may be provided with a brush unit and a drive mechanism for moving the brush unit between a stowed position and a deployed position.Type: GrantFiled: July 6, 2010Date of Patent: October 1, 2013Assignee: Dyson Technology LimitedInventors: Spencer James Robert Arthey, Henry Licming Lambourn, Stephen Robert Dimbylow, Alistair William Skuse

Patent number: 8387206Abstract: A surface treating head includes a main body; a brush unit; and a drive mechanism for moving the brush unit relative to the main body between a stowed position and a deployed position. The drive mechanism includes a pressure chamber and a valve unit for varying the pressure within the chamber. The valve unit includes a housing, a valve located within the housing and, disposed on the housing, an actuator moveable relative to the housing through engagement with a surface to be treated for operating the valve and at least one surface engaging member extending downwardly beyond the actuator. The housing is moveable relative to the main body to maintain the surface engaging member in contact with the surface to be treated.Type: GrantFiled: July 6, 2010Date of Patent: March 5, 2013Assignee: Dyson Technology LimitedInventors: Spencer James Robert Arthey, Stephen Robert Dimbylow, Alistair William Skuse
