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.

First claim

The invention claimed is:

1. A tool for a vacuum cleaner comprising a nozzle and a duct for attachment to the vacuum cleaner, wherein one or more suction openings are provided in a base of the nozzle, a front of the nozzle comprises a chamfered section adjoined to a further section, a suction opening is provided in the further section, the chamfered section is closed, and an internal angle formed between the chamfered section and the further section is greater than 90 degrees and less than 180 degrees.

2. The tool of claim 1 , wherein the chamfered section is longer than the further section.

3. The tool of claim 1 , wherein the top of the nozzle is closed.

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

5. The tool of claim 1 , wherein one or more suction openings are provided at an edge of the nozzle between the base and a side of the nozzle such that each suction opening is provided partly in the base and partly in the side of the nozzle.

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

7. The tool of claim 1 , wherein the internal angle is between 120 and 150 degrees.

8. The tool of claim 1 , wherein the chamfered section has a chamfer angle of between 30 and 60 degrees.

9. The tool of claim 1 , wherein the chamfered section has a chamfer angle of between 30 and 60 degrees relative to a first side of the nozzle, and the further section has a chamfer angle of 90 degrees relative to a second opposite side of the nozzle.

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

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

12. The tool of claim 1 , wherein one or more dirt-sweeping elements are provided on the base of the nozzle.

13. The tool of claim 12 , wherein each dirt-sweeping element comprises bristles.

14. A tool for a vacuum cleaner comprising a nozzle and a duct for attachment to the vacuum cleaner, wherein one or more suction openings are provided in a base of the nozzle, a front of the nozzle comprises a chamfered section adjoined to a further section, a suction opening is provided in the further section, the chamfered section is closed, the chamfered section has a chamfer angle of between 30 and 60 degrees relative to a first side of the nozzle, the further section has a chamfer angle of 90 degrees relative to a second opposite side of the nozzle, and the internal angle formed between the chamfered section and the further section is between 120 and 150 degrees.

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

16. The tool of claim 14 , wherein one or more suction openings are provided at an edge of the nozzle between the base and a side of the nozzle such that each suction opening is provided partly in the base and partly in the side of the nozzle.

17. The tool of claim 14 , wherein one or more dirt-sweeping elements are provided on the base of the nozzle.

18. The tool of claim 17 , wherein each dirt-sweeping element comprises bristles.

19. A tool for a vacuum cleaner comprising a nozzle and a duct for attachment to the vacuum cleaner, wherein the height of the nozzle is smaller than both the width and length of the nozzle, one or more suction openings are provided in a base of the nozzle, a front of the nozzle comprises a chamfered section adjoined to a further section, the chamfered section is longer than the further section, a suction opening is provided in the further section, the chamfered section is closed, and an internal angle formed between the chamfered section and the further section is greater than 90 degrees and less than 180 degrees.

20. The tool of claim 19 , wherein one or more suction openings are provided in at least one side of the nozzle.

21. The tool of claim 19 , wherein one or more suction openings are provided at an edge of the nozzle between the base and a side of the nozzle such that each suction opening is provided partly in the base and partly in the side of the nozzle.

22. The tool of claim 19 , wherein one or more dirt-sweeping elements are provided on the base of the nozzle.

23. The tool of claim 22 , wherein each dirt-sweeping element comprises bristles.
