Abstract

A low-profile and highly-maneuverable vacuum cleaner having improved functionality including, alone or in combination, a headlight, a sidelight, anti-ingestion bars, side brushes, a squeegee, and a scent cartridge for use in cleaning floors, floor coverings, carpets, upholstery, and other surfaces. One embodiment includes a tortuous air flow path created by baffles that divert air flow. The tortuous path creates quieter air flow through the vacuum housing. The tortuous air flow arrangement is for cooling the internal parts of a vacuum cleaner. Another embodiment includes an indicator light assembly for the vacuum cleaner visually providing the user with the vacuum'"'"'s current operation status. In another embodiment, the rear wheels are recessed within the head housing and slightly offset rearwardly of the rear wall of the head housing to provide enhanced maneuverability.

Claims

1. An anti-ingestion bar for a vacuum cleaner having a head housing, said bar comprising:

(a) at least two side arms, said at least two side arms including anti-ingestion portions; and

(b) a front bar portion extending between said at least two side arms, said front bar portion including at least one lateral support portion.

2. The anti-ingestion bar of claim 1, wherein said front bar portion is adapted to be joined to the head housing.

3. The anti-ingestion bar of claim 2, wherein said front bar portion is adapted to engage a bottom cover of the head housing.

4. The anti-ingestion bar of claim 1, wherein the head housing comprises holding tabs, wherein said at least one lateral support portion is adapted to be woven around and releasably held by the holding tabs.

5. The anti-ingestion bar of claim 1, wherein the front bar portion includes a joined series of co-planar, lateral support portions.

6. The anti-ingestion bar of claim 5, wherein said series of support portions of said front bar portion are adapted to weave between alternating holding tabs of the head housing to releasably secure the front bar portion to the head housing.

7. The anti-ingestion of claim 6, wherein the holding tabs are forwardly and rearwardly offset.

8. The anti-ingestion bar of claim 1, wherein said side arms are adapted to be releasably secured to the head housing.

9. The anti-ingestion bar of claim 8, wherein said side arms are adapted to be releasably secured to a lower surface of the head housing.

10. The anti-ingestion bar of claim 1, wherein said side arms are identical.

11. The anti-ingestion bar of claim 1, wherein said anti-ingestion portions are substantially horizontal.

12. The anti-ingestion bar of claim 1, wherein said anti-ingestion portions reside beneath a power roller brush located in the head housing.

13. The anti-ingestion bar of claim 1, wherein said side arms further comprise an upper connecting portion, a ramp portion, and a corner portion.

14. The anti-ingestion bar of claim 13, wherein said anti-ingestion portions are in a plane different from planes of said upper connecting portion, said ramp portion, and said corner portion.

15. The anti-ingestion bar of claim 1, further comprising rear anchor portions connected to said side arms.

16. The anti-ingestion bar of claim 15, wherein said side arms terminate at said rear anchor portions.

17. The anti-ingestion bar of claim 15, wherein said rear anchor portions are joined perpendicularly to said side arms.

18. The anti-ingestion bar of claim 15, wherein said rear anchor portions face in a same direction.

19. The anti-ingestion bar of claim 15, wherein said rear anchor portions face in opposite directions.

20. The anti-ingestion bar of claim 15, wherein said rear anchor portions define loops.

21. The anti-ingestion bar of claim 15, wherein said rear anchor portions are adapted to be releasably secured to the head housing.

22. The anti-ingestion bar of claim 21, wherein said rear anchor portions are adapted to be releasably secured to a lower surface of the head housing.

23. The anti-ingestion bar of claim 21, wherein said rear anchor portions are adapted to be releasably secured to the head housing via anchor slots.

24. The anti-ingestion bar of claim 21, wherein said rear anchor portions are adapted to be releasably secured to the head housing via one or more of the group selected from:

a screw, a heat stake, and a stub.

25. The anti-ingestion bar of claim 15, wherein said rear anchor portions are covered by a squeegee.

26. The anti-ingestion bar of claim 1, further comprising a corner portion joined between said anti-ingestion portion and said front bar portion.

27. The anti-ingestion bar of claim 26, wherein said corner portion is upwardly-curved.

28. The anti-ingestion bar of claim 26, wherein said corner portion terminates at a forward end of a corresponding side arm.

29. The anti-ingestion bar of claim 26, wherein said corner portion is joined to said front bar portion.

30. The anti-ingestion bar of claim 29, wherein said corner portion is joined to at least one of said lateral support portions of said front bar portion.

31. The anti-ingestion bar of claim 30, wherein said at least one of said lateral support portions is directed inwardly from said side arm.

32. The anti-ingestion bar of claim 30, wherein said at least one of said lateral support portions is generally perpendicular to said side arm.

33. The anti-ingestion bar of claim 1, wherein said side arms further comprise a ramp portion that extends rearwardly and upwardly from said anti-ingestion portions.

34. The anti-ingestion bar of claim 33, wherein said ramp portion is joined to an upper connecting portion opposite said anti-ingestion portion.

35. The anti-ingestion bar of claim 34, wherein said upper connecting portions of said side arms are horizontally directed.

36. The anti-ingestion bar of claim 34, wherein said upper connecting portion is connected to a rear anchor portion.

37. The anti-ingestion bar of claim 36, wherein said upper connecting portion resides in a same plane as said rear anchor portions and extends forwardly towards said front bar portion.

38. The anti-ingestion bar of claim 34, wherein said anti-ingestion portions reside in a plane lower to and parallel to a plane containing a corresponding upper connecting portion.

39. The anti-ingestion bar of claim 38, wherein said plane containing a corresponding upper connecting portion further includes a corresponding rear anchor portion.
