Abstract

A vacuum cleaner includes a housing having a handle pivotally mounted to a nozzle assembly. An agitator is received in an agitator cavity formed in the nozzle assembly. A suction fan and suction fan drive motor are carried on the housing. An edge cleaning brush is pivotally mounted to the nozzle assembly along a lateral edge of the nozzle assembly adjacent the agitator cavity. The brush includes a body having a series of apertures for receiving cleaning bristles and a pair of opposed mounting lugs. The edge cleaning brush is received in a recess with the mounting lugs held in a pair of opposed mounting openings in the nozzle assembly.

Claims

1. A vacuum cleaner, comprising:

a housing including a nozzle assembly;

a suction fan and suction fan drive motor carried on said housing; and

an edge cleaning brush mounted to an outer peripheral margin of said nozzle assembly so as to allow pivotal movement of said edge cleaning brush in a fore-and-aft direction relative to said nozzle assembly.

2. A vacuum cleaner, comprising;

a housing including a nozzle assembly and agitator cavity;

a suction fan and suction fan drive motor carried on said housing;

a driven rotary agitator received in said agitator cavity; and

an edge cleaning brush pivotally mounted to said nozzle assembly along a lateral edge of said nozzle assembly adjacent said agitator cavity so as to allow pivotal movement of said edge cleaning brush in a fore-and-aft direction relative to said nozzle assembly.

3. A vacuum cleaner, comprising:

a housing including a handle pivotally connected to a nozzle assembly;

an agitator cavity in said nozzle assembly;

an agitator received in said agitator cavity and mounted for rotation relative to said nozzle assembly;

a suction fan and suction fan drive motor carried on said housing; and

an edge cleaning brush pivotally mounted to said nozzle assembly along a lateral edge of said nozzle assembly adjacent said agitator cavity.

4. The vacuum cleaner of claim 3, wherein said edge cleaning brush includes a body having a series of apertures for receiving cleaning bristles and a pair of opposed mounting lugs.

5. The vacuum cleaner of claim 4, wherein said nozzle assembly includes a recess defined between a pair of opposing sidewalls and a pair of opposed openings for receiving said mounting lugs, one of said opposed openings being provided in each of said pair of sidewalls.

6. The vacuum cleaner of claim 5, wherein said recess includes a pair of walls limiting pivotal movement of said edge cleaning brush through an arc of between 20°

-80°

.

7. The vacuum cleaner of claim 6, wherein said recess extends across said nozzle assembly between a side edge thereof to an agitator cavity opening in said nozzle assembly.

8. The vacuum cleaner of claim 7, wherein said recess is positioned on said nozzle assembly in front of said agitator cavity opening.

9. The vacuum cleaner of claim 3, wherein said nozzle assembly is hammerhead shaped.

10. The vacuum cleaner of claim 3, wherein said edge cleaning brush extends transversely across said nozzle assembly from a peripheral side edge thereof inwardly so as to overlap said agitator.

11. A vacuum cleaner, comprising:

a housing including a nozzle assembly;

a suction fan and suction fan drive motor carried on said housing; and

an edge cleaning brush pivotally mounted to an outer peripheral margin of said nozzle assembly, said edge cleaning brush including a body having a series of apertures for receiving cleaning bristles and a pair of opposed mounting lugs.

12. The vacuum cleaner of claim 11, wherein said nozzle assembly includes a recess defined between a pair of opposing sidewalls and a pair of opposed openings for receiving said mounting lugs, one of said pair of opposed openings being provided in each of said pair of sidewalls.

13. The vacuum cleaner of claim 12, wherein said recess includes a pair of walls limiting pivotal movement of said edge cleaning brush through an arc of between 20°

-80°

.

14. The vacuum cleaner of claim 13, wherein said recess extends across said nozzle assembly between a side edge thereof to an agitator cavity opening in said nozzle assembly.

15. The vacuum cleaner of claim 14, wherein said recess is positioned on said nozzle assembly in front of said agitator cavity opening.

16. A vacuum cleaner, comprising;

a housing including a nozzle assembly and agitator cavity;

a suction fan and suction fan drive motor carried on said housing;

a driven rotary agitator received in said agitator cavity; and

an edge cleaning brush pivotally mounted to said nozzle assembly along a lateral edge of said nozzle assembly adjacent said agitator cavity, said edge cleaning brush including a body having a series of apertures for receiving cleaning bristles and a pair of opposed mounting lugs.

17. The vacuum cleaner of claim 16, wherein said nozzle assembly includes a recess defined between a pair of opposing sidewalls and a pair of opposed openings for receiving said mounting lugs, one of said pair of opposed openings being provided in each of said sidewalls.

18. The vacuum cleaner of claim 17, wherein said recess includes a pair of walls limiting pivotal movement of said edge cleaning brush through an arc of between 20°

-80°

.

19. The vacuum cleaner of claim 18, wherein said recess extends across said nozzle assembly between a side edge thereof to an agitator cavity opening in said nozzle assembly.

20. The vacuum cleaner of claim 19, wherein said recess is positioned on said nozzle assembly in front of said agitator cavity opening.
