Abstract

A tool for a vacuum cleaner that comprises a nozzle and a bristle assembly. The nozzle comprises an elongate suction opening. The bristle assembly, which is mounted within the nozzle and protrudes through the suction opening, comprises a carrier to which a strip of bristles is attached.

First claim

The invention claimed is:

1. A tool for a vacuum cleaner, the tool comprising a nozzle and a bristle assembly, wherein a base of the nozzle comprises an elongate suction opening delimited along its length by a leading edge and a trailing edge of the base, the bristle assembly is mounted within the nozzle and protrudes through the suction opening, the bristle assembly comprises a carrier to which a strip of bristles is attached, the carrier is formed of a flexible material and protrudes beyond the suction opening such that the carrier is able to flex to contact the trailing edge, wherein the leading and trailing edges of the base extend longitudinally from a first end of the base to a second end of the base and are raised relative to the first and second ends of the base so that when the first and second ends of the base are in contact with a surface during use, the leading and trailing edges are raised above the surface to be cleaned forming a gap between the nozzle and the surface to be cleaned.

2. The tool of claim 1 , wherein the carrier flexes and contacts the trailing edge when the tool is swept over a cleaning surface in a first direction, and the carrier flexes and contacts the leading edge when the tool is swept over the cleaning surface in a second opposite direction.

3. The tool of claim 1 , wherein the carrier comprises one or more through-holes.

4. The tool of claim 3 , wherein the tool comprises a duct for attachment to a wand or hose of the vacuum cleaner, the suction opening extends from a front to a rear of the nozzle, the duct is attached to the rear of nozzle, and the through-holes are formed in a region of the carrier proximate the rear of the nozzle.

5. The tool of claim 3 , wherein the carrier comprises through-holes of different sizes.

6. The tool of claim 3 , wherein the tool comprises a duct for attachment to a wand or hose of the vacuum cleaner, the suction opening extends from a front to a rear of the nozzle, the duct is attached to the rear of nozzle, the carrier comprises a first through-hole and a second through-hole, and the first through-hole is larger and located closer to the rear of nozzle than that of the second through-hole.

7. The tool of claim 1 , wherein the bristle assembly is attached along a top of the nozzle.

8. The tool of claim 1 , wherein the tool comprises a duct for attachment to a wand or hose of the vacuum cleaner, the suction opening extends from a front to a rear of the nozzle, the duct is attached to the rear of nozzle, and the height or width of the nozzle tapers from the rear to the front of the nozzle.

9. The tool of claim 1 , wherein the carrier is formed of rubber.

10. The tool of claim 1 , wherein the bristles are formed of carbon fibre.

11. A tool for a vacuum cleaner, the tool comprising a nozzle and a bristle assembly, wherein the nozzle comprises an elongate suction opening that extends from a front to a rear of the nozzle, the suction opening is delimited along its length by a leading edge and a trailing edge, the bristle assembly is mounted within the nozzle and protrudes through the suction opening, the bristle assembly comprises a strip of bristles attached to a carrier, the carrier extends beyond the suction opening and is arranged to pivot or flex relative to the nozzle such that, as the tool is swept over a cleaning surface, the carrier pivots or flexes and contacts the trailing edge, and the carrier comprises one or more through-holes that provide airflow passageways between a leading side and a trailing side of the bristle assembly such that the pressure difference between the leading side and the trailing side is reduced by allowing airflow to pass through the through-holes.

12. The tool of claim 11 , wherein the carrier pivots or flexes and contacts the trailing edge when the tool is swept over a cleaning surface in a first direction, and the carrier pivots or flexes and contacts the leading edge when the tool is swept over the cleaning surface in a second opposite direction.

13. The tool of claim 11 , wherein the tool comprises a duct for attachment to a wand or hose of the vacuum cleaner, the suction opening extends from a front to a rear of the nozzle, the duct is attached to the rear of nozzle, and the through-holes are formed in a region of the carrier proximate the rear of the nozzle.

14. The tool of claim 11 , wherein the carrier comprises through-holes of different sizes.

15. The tool of claim 11 , wherein the tool comprises a duct for attachment to a wand or hose of the vacuum cleaner, the suction opening extends from a front to a rear of the nozzle, the duct is attached to the rear of nozzle, the carrier comprises a first through-hole and a second through-hole, and the first through-hole is larger and located closer to the rear of nozzle than that of the second through-hole.

16. The tool of claim 11 , wherein the bristle assembly is attached along a top of the nozzle.

17. The tool of claim 11 , wherein the tool comprises a duct for attachment to a wand or hose of the vacuum cleaner, the suction opening extends from a front to a rear of the nozzle, the duct is attached to the rear of nozzle, and the height or width of the nozzle tapers from the rear to the front of the nozzle.

18. The tool of claim 11 , wherein the carrier is formed of rubber.

19. The tool of claim 11 , wherein the bristles are formed of carbon fibre.
