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.

First claim

The invention claimed is:

1. A tool for a vacuum cleaner comprising a duct for attachment to the vacuum cleaner, a nozzle and one or more dirt-sweeping elements, wherein the nozzle comprises two sides that extend between a front and a rear of the nozzle, the duct is attached to the rear of the nozzle, 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 provided in the base of the nozzle, each suction opening is located within a respective chevron, and the area of each suction opening is no more than 20% of the area delimited by the respective chevron.

2. The tool of claim 1 , wherein each dirt-sweeping element forms a continuous curtain.

3. The tool of claim 1 , wherein each suction opening is spaced from the dirt-sweeping elements.

4. The tool of claim 3 , wherein the dirt-sweeping elements comprise bristles, and each suction opening is spaced from the dirt-sweeping elements by at least a distance corresponding to the length of the bristles.

5. The tool of claim 1 , wherein the suction openings are triangular in shape.

6. The tool of claim 1 , wherein one or more further suction openings are provided in at least one side of the nozzle.

7. The tool of claim 6 , wherein each further suction opening is provided at an edge of the nozzle between the base and a side of the nozzle such that each further suction opening is provided partly in the base and partly in the side of the nozzle.

8. The tool of claim 6 , wherein each suction opening has a respective further suction opening.

9. The tool of claim 1 , wherein the front of the nozzle is chamfered.

10. The tool of claim 9 , wherein the front of the nozzle comprises a chamfered section and a further section, the chamfered section is closed and a suction opening is provided in the further section.

11. The tool of claim 1 , wherein the height of the nozzle is smaller than both the width and length of the nozzle.

12. The tool of claim 1 , wherein the duct extends rearwards from the nozzle along an axis parallel to the base of the nozzle.

13. The tool of claim 1 , wherein the height of the duct is smaller than the width of the duct.

14. A tool for a vacuum cleaner comprising a duct for attachment to the vacuum cleaner, a nozzle and one of more dirt-sweeping elements, wherein the nozzle comprises two sides that extend between a front and a rear of the nozzle, the height of the nozzle is smaller than both the width and length of the nozzle, the length of the nozzle is greater than the width of the nozzle, the duct extends rearwards from the nozzle, 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, and at least two suction openings are provided in the base of the nozzle, each suction opening being located within a chevron.

15. The tool of claim 14 , wherein each suction opening is spaced from the dirt-sweeping elements.

16. The tool of claim 15 , wherein the dirt-sweeping elements comprise bristles, and each suction opening is spaced from the dirt-sweeping elements by at least a distance corresponding to the length of the bristles.

17. The tool of claim 14 , wherein the suction openings are triangular in shape.

18. The tool of claim 14 , wherein one or more further suction openings are provided in at least one side of the nozzle.

19. A tool for a vacuum cleaner comprising a duct for attachment to the vacuum cleaner, a nozzle and one of more dirt-sweeping elements, wherein the nozzle comprises two sides that extend between a front and a rear of the nozzle, the duct is attached to the rear of the nozzle, the height of the nozzle is smaller than both the width and length of the nozzle, 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 provided in the base of the nozzle, each suction opening being located within a chevron, and one or more further suction openings are provided in at least one of the sides of the nozzle.

20. The tool of claim 19 , wherein each further suction opening is provided at an edge of the nozzle between the base and a side of the nozzle such that each further suction opening is provided partly in the base and partly in the side of the nozzle.

21. The tool of claim 19 , wherein each suction opening is spaced from the dirt-sweeping elements.

22. The tool of claim 21 , wherein the dirt-sweeping elements comprise bristles, and each suction opening is spaced from the dirt-sweeping elements by at least a distance corresponding to the length of the bristles.

23. The tool of claim 19 , wherein the suction openings are triangular in shape.

24. A tool for a vacuum cleaner comprising a duct for attachment to the vacuum cleaner, a nozzle and one or more dirt-sweeping elements, wherein a base of the nozzle is flat, the dirt-sweeping elements are secured to the 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 provided in the base of the nozzle, each suction opening is located within a chevron, the dirt-sweeping elements comprise bristles, and each suction opening is spaced from the dirt-sweeping elements by at least a distance corresponding to the length of the bristles.

25. The tool of claim 24 , wherein the suction openings are triangular in shape.

26. The tool of claim 24 , wherein one or more further suction openings are provided in at least one side of the nozzle.

27. The tool of claim 26 , wherein each further suction opening is provided at an edge of the nozzle between the base and a side of the nozzle such that each further suction opening is provided partly in the base and partly in the side of the nozzle.

28. The tool of claim 26 , wherein each suction opening has a respective further suction opening.

29. A tool for a vacuum cleaner comprising a duct for attachment to the vacuum cleaner, a nozzle and one or more dirt-sweeping elements, wherein the front of the nozzle is chamfered, 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, and at least two suction openings are provided in the base of the nozzle, each suction opening being located within a chevron.

30. The tool of claim 29 , wherein the front of the nozzle comprises a chamfered section and a further section, the chamfered section is closed and a suction opening is provided in the further section.
