Abstract

A floor care appliance such as a vacuum cleaner is provided having a traction wheel powered edge cleaner comprised of a vertical axis rotary agitator which is affixed to either the right or left side of the suction nozzle. The agitator is rotated by the traction wheel when the vacuum cleaner is disposed along a wall surface and moved relative to the wall surface. The rotating action of the agitator sweeps dirt particles off of the wall surface and along the edge of the wall surface into the path of the suction nozzle for pickup. When not in use the edge cleaner is stored in the accessory storage rack like other accessory tools. The agitator can have differing agitator elements such as bristles or a fluff wheel.

Claims

1. An edge cleaning device for a floor care appliance having a base moved over a floor surface to be cleaned, comprising:

an agitator body having an outer periphery and capable of rotation about an axis;

a plurality of radially extending bristles circumscribing the outer periphery of said agitator body; and

a traction wheel coupled to the agitator body for rotating the agitator body about said axis;

wherein said edge cleaning device is attached to an exterior of said base of said floor care appliance and said traction wheel is rotated by engaging a wall surface adjacent a floor edge to be cleaned when said floor care appliance is moved past said wall surface.

2. The edge cleaner of claim 1, further including a mounting member for mounting said edge cleaner on an outer periphery of said base.

3. The edge cleaner of claim 2, wherein said mounting member includes a latch member for securing said mounting member to said outer periphery of said base.

4. The edge cleaner of claim 3, wherein said base includes a receiving socket for receiving said mounting member.

6. The edge cleaner of claim 1, wherein said base is a suction nozzle.

7. The edge cleaner of claim 1, wherein said axis is vertical.

5. The edge cleaner of claim 5, wherein said latch member is biased in the latched position when said mounting member is received by said receiving socket.

8. An improved floor care appliance, comprised of:

a suction nozzle having an outer periphery;

a handle;

a suction motor for generating an air stream originating at the suction nozzle;

a filtration system fluidly connected to the suction nozzle; and

a vertical axis rotary agitator arrangement attached to the outer periphery of said suction nozzle.

9. The improved floor care appliance of claim 8, wherein said vertical axis rotary agitator arrangement is rotated by a member of the group consisting of a traction wheel, turbine, motor, gear drive from a rotary power source and belt drive from a rotary power source.

10. The improved floor care appliance of claim 8, wherein said vertical axis rotary agitator arrangement is pivotally attached to the outer periphery of said suction nozzle, said vertical axis rotary agitator arrangement having a first position non-use position and pivoted into a second operative position when in use.

11. The improved floor care appliance of claim 8, wherein said vertical axis rotary agitator arrangement is removably attached to the outer periphery of said suction nozzle.

12. The improved floor care appliance of claim 11, wherein said vertical axis rotary agitator arrangement includes a mounting member for attaching said vertical axis rotary agitator arrangement to the outer periphery of said suction nozzle.

13. The improved floor care appliance of claim 12, wherein said mounting member includes a latch member for securing said vertical axis rotary agitator arrangement to the outer periphery of said suction nozzle.

14. The improved floor care appliance of claim 13, wherein said latch member is biased into a locked position when said vertical axis rotary agitator arrangement is mounted to the outer periphery of said suction nozzle.

15. The improved floor care appliance of claim 8, wherein said vertical axis rotary agitator arrangement includes a main body member having at least one agitator member attached thereon.

16. The improved floor care appliance of claim 15, wherein said at least one agitator member is a member of the group consisting of bristles, lambs wool, felt, feathers and fluff pad.

17. The improved floor care appliance of claim 10, wherein said traction wheel is rotatably coupled to said vertical axis rotary agitator arrangement by a belt and pulley arrangement for rotating said vertical axis rotary agitator arrangement.

18. An improved floor care appliance, comprised of:

a suction nozzle having an outer periphery;

a handle;

a suction motor for generating an air stream originating at the suction nozzle;

a filtration system fluidly connected to the suction nozzle; and

a rotary agitator arrangement attached to the outer periphery of said suction nozzle.

19. The improved floor care appliance of claim 18, further including a suction port formed in the outer periphery of the suction nozzle on the right and left edges of said suction nozzle.

20. The improved floor care appliance of claim 19, further including a gate biased in the closed position installed in each of said suction ports formed in the outer periphery of the suction nozzle on the right and left edges of said suction nozzle.

21. The improved floor care appliance of claim 20, wherein said rotary agitator arrangement further includes a mounting member having a gate opening member which opens said gate when said rotary agitator arrangement is installed on said suction nozzle.

22. The improved floor care appliance of claim 18, further including a suction port formed in the outer periphery of the suction nozzle on the front edge on the right and left hand sides of said suction nozzle.

23. The improved floor care appliance of claim 22, further including a gate a biased in the closed position installed in each of said suction ports formed in the outer periphery of the suction nozzle on the front edge on the right and left hand sides of said suction nozzle.

24. The improved floor care appliance of claim 23, wherein said rotary agitator arrangement further includes a mounting member having a gate opening member which opens said gate when said rotary agitator arrangement is installed on said suction nozzle.

25. The improved floor care appliance of claim 18, wherein said rotary agitator arrangement is rotated by a member of the group consisting of a traction wheel, turbine, motor, gear drive from a rotary power source and belt drive from a rotary power source.

26. The improved floor care appliance of claim 18, wherein said rotary agitator arrangement is coupled to a rotary power source by a transmission arrangement selected from a member of the group consisting of planetary gears, belt and pulleys, toothed gears, and helical and worm gears.

27. The improved floor care appliance of claim 26, wherein said transmission increases the rotary speed of the rotary agitator arrangement over the rotary speed of the rotary power source.

28. The improved floor care appliance of claim 26, wherein said transmission decreases the rotary speed of the rotary agitator arrangement over the rotary speed of the rotary power source.

29. The improved floor care appliance of claim 26, wherein said transmission rotates the rotary agitator arrangement in the same direction as the rotary power source.

30. The improved floor care appliance of claim 26, wherein said transmission rotates the rotary agitator arrangement in the opposite direction as the rotary power source.

31. A method of edge cleaning, comprised of the steps of.

providing a floor care appliance having a suction nozzle having an outer periphery, a suction motor, a handle, and a particle collecting and filtration arrangement;

placing a rotary agitator powered by a traction wheel on the outer periphery of the suction nozzle;

placing the traction wheel in operative engagement with a wall surface adjoining an edge to be cleaned;

moving the suction nozzle over a floor surface such that the traction wheel is rotated by engaging the wall surface and particles are swept into the path of the suction nozzle; and

removing the swept particles by moving the suction nozzle over the particles.
