Abstract

An upright vacuum cleaner includes a housing having a handle assembly pivotally connected to a nozzle assembly. A suction generator and dirt collection vessel are carried on the housing. The suction generator includes a drive motor. A rotary agitator assembly and a suction inlet are carried on the nozzle assembly. The rotary agitator assembly includes an axle, a drive pulley mounted on the axle, an agitator body mounted on the axle and a clutch assembly. The clutch assembly includes a first clutch element, a second clutch element, a first biasing spring, a second biasing spring and an actuator that allows the operator to selectively engage and disengage the clutch assembly.

Claims (15)

1. An upright vacuum cleaner, comprising:
a housing including a handle assembly pivotally connected to a nozzle assembly, said nozzle assembly including a suction inlet;
a suction generator carried on said housing, said suction generator including a drive motor;
a dirt collection vessel carried on said housing; and a rotary agitator assembly carried on said nozzle assembly, said rotary agitator assembly including an axle, a drive pulley mounted on said axle, an agitator body mounted on said axle and a clutch assembly;
said clutch assembly including a first clutch element carried on said drive pulley, a second clutch element carried on said agitator body, a first spring biasing said first and second clutch elements apart with a biasing force F1, a second spring biasing said first and second clutch elements together with a biasing force F2, a spring holder holding said second spring and an actuator to selectively engage and displace said spring holder and thereby disengage said clutch assembly and interrupt drive to said agitator body.
2. The vacuum cleaner of claim 1, wherein said biasing force F2 of said second spring is greater than said biasing force F1 of said first spring.
3. The vacuum cleaner of claim 2, wherein said agitator body includes a first end cap at a first end and a second end cap at a second end.
4. The vacuum cleaner of claim 3, further including a first bearing assembly held in said first end cap and a second bearing assembly held in said second end cap, said first and second bearing assemblies allowing said agitator body to rotate freely on said axle.
5. The vacuum cleaner of claim 4, further including a third bearing assembly held in said drive pulley, said third bearing assembly allowing said drive pulley to rotate freely on said axle.
6. The vacuum cleaner of claim 5, further including a first mounting block at a first end of said axle and a second mounting block at a second end of said axle.
7. The vacuum cleaner of claim 6, wherein said actuator is carried by said second mounting block.
8. The vacuum cleaner of claim 7, wherein said spring holder includes a flange and said actuator includes a cam.
9. The vacuum cleaner of claim 8, wherein said cam includes a sloped surface that engages said flange or said spring holder.
10. The vacuum cleaner of claim 9, wherein said actuator is displaceable between a first position out of engagement with said flange wherein said clutch assembly is engaged and said agitator body is driven and a second position wherein said clutch assembly is disengaged and drive to said agitator body is interrupted.
11. The vacuum cleaner of claim 1, wherein said dirt collection vessel is a dirt cup.
12. The vacuum cleaner of claim 11, wherein said dirt cup includes a cylindrical sidewall, a tangentially directed inlet and an axially directed outlet.
13. The vacuum cleaner of claim 12, further including a primary filter received in said dirt cup over said axially directed outlet.
14. The vacuum cleaner of claim 1, wherein said dirt collection vessel is a filter bag.
15. The vacuum cleaner of claim 1, wherein said second clutch element is made from rubber.
