Patent application numberDescriptionPublished
20090106932CLEANING APPLIANCE - A cleaning appliance includes a main body, including a motor and fan unit for generating an airflow, a separating apparatus for separating dirt and dust from the airflow and a passageway for receiving a filter. The passageway and a filter may be located downstream of the separating apparatus and upstream of the motor, and the filter may have an at least partially curved filter surface. The filter is arranged around at least a part of the motor and fan unit. The filter is removable through a side, and through a wheel, of the appliance. The arrangement facilitates ease of removal of the filter from the cleaning appliance.04-30-2009
20090300875SUPPORT ASSEMBLY - A support assembly for a surface treating appliance includes a central roller arranged to engage a surface and outer rollers at either end of the central roller. The rollers together define a rolling support surface, and the outer rollers rotate about an axis spaced from the rotational axis of the central roller. This arrangement of rollers provides a rolling support surface over a wide range of motions, and spacing the rotational axes of the rollers permits the rollers to be arranged relative to one another to define a region into which components of the appliance are mountable.12-10-2009
20100294208ATTACHMENT FOR A VACUUM CLEANING APPLIANCE - A grooming device includes a head and a handle. A first end of the handle is connected to the head, and a second end of the handle is connectable to a vacuum cleaning appliance. The head includes a bristle carrier having a plurality of bristles, and a bristle cover having a plurality of apertures. The device includes an actuator manually operable by a user to effect relative movement between the bristle carrier and the bristle cover from a stowed configuration in which the bristles are retracted relative to the bristle cover to a deployed configuration in which the bristles protrude from the bristle cover through the apertures. The handle includes a conduit for conveying an air flow from the head to the second end of the handle. Resilient members are provided for returning the head to the stowed configuration automatically when the actuator is released by the user. In addition to enabling hair or other matter collected between the bristles of the bristle carrier to be readily dislodged from the device, the automatic retraction of the bristles can ensure that the bristles are not exposed when the device is not in use.11-25-2010
20100306956CLEANER HEAD - Agitating apparatus for a surface treating appliance includes a rotatable body having a plurality of grooves formed therein, an agitating member located within each groove so that at least one side edge of the agitating member protrudes outwardly from the body, and a connecting member located within each groove for connecting the agitating member to the body.12-09-2010
20100306957CLEANER HEAD - A cleaner head for a surface treating appliance includes a housing and a rotatable brush bar located within the housing. The brush bar includes a first plurality of bristles and a second plurality of bristles which protrude radially outwardly beyond the first plurality of bristles. The second plurality of bristles has a surface resistivity in the range from 1×1012-09-2010
20100306958CLEANER HEAD - Agitating apparatus for a surface treating appliance includes a rotatable body having an outer surface comprising an electrically conductive pile formed from filaments having a surface resistivity in the range from 1×1012-09-2010
20100306959CLEANER HEAD - Agitating apparatus for a surface treating appliance includes a rotatable body having at least one substantially continuous row of bristles extending outwardly therefrom, the bristles having a surface resistivity in the range from 1×1012-09-2010
20100319159TOOL FOR A SURFACE TREATING APPLIANCE - A tool for a surface treating appliance includes a main body connected to a conduit. The main body includes a first suction channel and a second suction channel in fluid communication with the first suction channel and located between the first suction channel and an outlet from the main body. In use, a relatively low vacuum is generated in the first suction channel which draws a first dirt-bearing fluid flow into the main body, and a relatively high vacuum is generated in the second suction channel, which draws a second dirt-bearing fluid flow into the main body and receives the first dirt-bearing fluid flow from the first suction channel. To maintain the pressure differences between the suction channels, the main body includes flexible surface engaging members located about the suction channels, and between the first suction channel and the second suction channel.12-23-2010
20110088195SURFACE TREATING APPLIANCE - 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 and a pair of wheels rotatably connected to the yoke, the yoke being shaped so that a section of the yoke lies between the rims of the wheels. A surface treating head is connected to the yoke. The main body is pivotably connected to the yoke for movement about a pivot axis passing between the wheels, and so that a part of the main body is located between the rims of the wheels. As the main body is pivoted about said axis from an upright position to a reclined position, the spacing between said section of the yoke and said part of the main body increases, and so a shield is provided for covering the gap so formed between said section of the yoke and said part of the main body to prevent dirt and dust from passing into the support assembly through the gap.04-21-2011
20110088196SURFACE TREATING APPLIANCE - An upright surface treating appliance includes a main body having a user operable handle, a surface treating head connected to a yoke moveable relative to the main body, a stand moveable relative to both the main body and the yoke between a supporting position for supporting the main body in an upright position, and a retracted position, and a stand retaining mechanism for releasably retaining the stand in the supporting position and from which the stand is releasable upon application of a force to one of the main body and the stand. The yoke is moveable relative to the main body in response to an impact on the surface treating head to apply said force to the stand. This allows the force of the impact on the surface treating head to be transferred through the stand to the stand retaining mechanism, which, depending on the magnitude of the impact, can release both the stand and the yoke for movement relative to the main body. This avoids the need to provide separate releasing mechanisms for both the yoke and the stand.04-21-2011
20110088198SURFACE TREATING APPLIANCE - 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.04-21-2011
20110088205SURFACE TREATING APPLIANCE - 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.04-21-2011
20110088211SURFACE TREATING APPLIANCE - 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.04-21-2011
