Abstract

A cleaning appliance comprising a body that is connectable to a separating apparatus at an interface that defines an axis. The interface includes a first interface portion and a second interface portion that are connected to one another by a connector, wherein the connector includes at least one radially interlocking region extending about at least a portion of the interface.

Claims

1. A cleaning appliance comprising a body that is connectable to a separating apparatus at an interface defining an axis, the interface including a first interface portion and a second interface portion that are connected to one another by a connector, wherein the connector includes at least one radially interlocking region extending about at least a portion of the interface.

2. The cleaning appliance of claim 1, including two or more radially interlocking regions.

3. The cleaning appliance of claim 2, wherein at least two or more of the radially interlocking regions oppose one another.

4. The cleaning appliance of claim 1, wherein the connector includes a connecting member captive on the first interface portion and operable to lock onto one or more radial catch regions provided on the second interface portion.

5. The cleaning appliance of claim 4, wherein the connecting member is a part-circular fastener that is compressible in the radial direction.

6. The cleaning appliance of claim 4, wherein the connecting member is pivoted at one end.

7. The cleaning appliance of claim 6, including a further connecting member also pivoted at one end.

8. The cleaning appliance of claim 4, wherein the connecting member includes oblique faces which are operable to compress the connecting member in a radial direction when the first interface portion is brought into engagement with the second interface portion so that the resilient member engages with the catch regions.

9. The cleaning appliance of claim 4, wherein the connecting member is retained in an internal chamber defined by the first interface portion.

10. The cleaning appliance of claim 1, wherein the first and second interface portions have circular cross sections.

11. The cleaning appliance of claim 1, including an airflow generator for drawing air into the appliance and through the separating apparatus, wherein an airflow path from the separating apparatus to the main body is defined internally through the interface.

12. The cleaning appliance of claim 1, wherein the first interface portion is associated with the main body and the second interface portion is associated with the separating apparatus.

13. The cleaning appliance of claim 4, wherein the interface includes an access port that permits a tool to be inserted into the interface to engage the connector.

14. The cleaning appliance of claim 4, wherein the interface includes one or more user-operable buttons associated with the connector operable to selectively engage and disengage the connector.

15. (canceled)

16. An apparatus in a household appliance comprising a first component that is releasably connected to a second component at an interface, the interface including a first interface portion and a second interface portion, and a connector including at least one radially interlocking region extending about at least a portion of the interface.

17. The apparatus of claim 16 wherein at least two of the engagement points lie on different planes

18. The apparatus of claim 16, including two or more radially interlocking regions.

19. The apparatus of claim 18, wherein at least two or more of the radially interlocking regions oppose one another.

20. The apparatus of claim 16, wherein the connector includes a connecting member captive on the first interface portion and operable to lock onto one or more catch regions provided on the second interface portion.

21. The apparatus of claim 20, wherein the connecting member is a part-circular fastener that is compressible in the radial direction.

22. The apparatus of claim 20, wherein the connecting member is pivoted at one end.

23. The apparatus of claim 22, including a further connecting member also pivoted at one end.

24. The apparatus of claim 20, wherein the connecting member includes oblique faces which are operable to compress the connecting member in a radial direction when the first interface portion is brought into engagement with the second interface portion so that the connecting member engages with the catch regions.

25. The apparatus of claim 16, wherein the first and second interface portions have circular cross sections.

26. The apparatus of claim 16, wherein the interface includes one or more user-operable buttons associated with the connector operable to selectively engage and disengage the connector.
