Abstract: A vacuum cleaner flexible duct. The flexible duct includes a helical frame and a helical strip. The helical frame includes a plurality of loops arranged about a helical axis and is formed of a rigid material. The helical strip is provided on the helical frame to seal the flexible duct and is formed of pliable material and. At least one loop of the helical frame has one or more projections that extend towards an adjacent loop. The projections limit the flexing of the flexible duct in a direction normal to the helical axis.

Abstract: A vacuum cleaner flexible duct. The flexible duct includes a helical frame and a helical strip. The helical frame is formed of a rigid material and includes a plurality of loops spaced about a helical axis. The helical strip is formed of pliable material and is provided between the loops of the helical frame to seal the frame. Each loop of the frame includes a central band with at least one wing. The helical strip is secured to the at least one wing such that the exterior surface of the helical strip is flush with the exterior surface of the central band.

Abstract: A vacuum cleaner flexible duct. The flexible duct includes a helical frame and a helical strip. The helical frame includes a plurality of loops arranged about a helical axis and is formed of a rigid material. The helical strip is provided between the loops to seal the frame and is formed of pliable material. The helical strip has indents on an exterior surface of the duct. The helical strip is secured to the loops such that the interior surface of the helical strip is flush with the interior surface of the loops.

Abstract: A cleaner head for a cleaning appliance, comprising a brushbar, a housing defining a chamber which at least partially surrounds the brushbar, the chamber having a dirty air inlet and a dirty air outlet, and a scraper having a working edge which extends in the longitudinal direction of the brushbar. The scraper is arranged such that, in use, the working edge scrapes debris entrained by the brushbar from the brushbar. The working edge has a profile which is shaped such that debris which accumulates at the working edge is drawn by the airflow through the cleaner head along the working edge towards the dirty air outlet.

Abstract: A tool for a vacuum cleaner comprising a duct for attachment to a wand, hose or the like of the vacuum cleaner, a nozzle and one of more dirt-sweeping elements. The dirt-sweeping elements are secured to a base of the nozzle and are arranged into at least two chevrons oriented in opposite directions towards the sides of the nozzle. At least two suction openings are then provided in the base of the nozzle, each suction opening being located within a chevron.

Abstract: A tool for a vacuum cleaner that includes a nozzle and a bristle assembly. An elongate suction opening is provided in a base of the nozzle. The bristle assembly is mounted within the nozzle and includes a carrier to which a strip of bristles is attached. The carrier pivots or flexes relative to the nozzle and has a pair of wings located on opposite sides of the bristles.

Abstract: A tool for a vacuum cleaner that includes a nozzle and a duct for attachment to a wand, hose or the like of the vacuum cleaner. One or more suction openings are provided in a base of the nozzle. The front of the nozzle includes a chamfered section and a further section. A suction opening is then provided in the further section, and the chamfered section is closed. The internal angle formed between the chamfered section and the further section is greater than 90 degrees and less than 180 degrees.
