Abstract
Official abstract text for this publication.
A tool for a vacuum cleaner that comprises a nozzle and a bristle assembly. A suction opening is provided in the base of the nozzle, which extends from a front to a rear of the nozzle. The bristle assembly is mounted within the nozzle and protrudes through the suction opening. The suction opening is delimited along its length by a leading edge and a trailing edge, and at least part of the leading edge is raised relative to a front end and a rear end of the nozzle. Consequently, when the tool is swept over a cleaning surface and the front end and the rear end of the nozzle contact the cleaning surface, a gap is created between the cleaning surface and the leading edge.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tool for a vacuum cleaner, the tool comprising a nozzle and a bristle assembly, wherein a suction opening is provided in a base of the nozzle, the suction opening is elongate and extends from a front to a rear of the nozzle, the bristle assembly is mounted within the nozzle and protrudes through the suction opening, the suction opening is delimited along its length by a leading edge and a trailing edge, and at least part of the leading edge is raised relative to a front end and a rear end of the nozzle such that, when the tool is swept over a cleaning surface, the front end and the rear end of the nozzle contact the cleaning surface and a gap is created between the cleaning surface and the leading edge. 2. The tool of claim 1 , wherein at least part of the trailing edge is raised relative to the front end and the rear end of the nozzle. 3. The tool of claim 1 , wherein the front end and the rear end of the nozzle are curved. 4. The tool of claim 1 , wherein a protective pad is secured to the front end and the rear end of the nozzle. 5. The tool of claim 1 , wherein the bristle assembly is attached along a top of the nozzle. 6. The tool of claim 1 , wherein the bristle assembly comprises a carrier to which a strip of bristles is attached, and the carrier is arranged to pivot or flex relative to the nozzle. 7. The tool of claim 6 , wherein the carrier is arranged to pivot or flex relative to the nozzle such that the carrier contacts the trailing edge when the tool is swept over the cleaning surface in a first direction and the carrier contacts the leading edge when the tool is swept over the cleaning surface in a second opposite direction. 8. The tool of claim 1 , wherein the bristle assembly comprises a strip of bristles formed of carbon fibre.
