Abstract

A vacuum cleaning tool adapter for vacuum cleaning systems having a control device incorporated within the adapter. The control device includes an electrical switch and may also include other circuit control devices. Also incorporated in the adapter is a connect-disconnect connector for mechanically interengaging the adapter with a hose assembly leading to the vacuum cleaner, which also provides electrical continuity from the adapter through current conducting reinforcing members in the hose assembly and into the vacuum cleaner. The adapter provides for electrically connecting the cleaning tool into the system, and the switch is used to turn the power on and off from the vacuum cleaner motor to the cleaning tool. An additional switch may also be located in the adapter for controlling the vacuum cleaner motor itself.

Claims

1. In a vacuum cleaning system comprising a vacuum cleaner, a hose assembly, a cleaning tool adapter and a cleaning tool;

said hose assembly comprising a flexible cylindrical body, a plurality of spaced helically coiled reinforcing wires extending along said body and also serving as electrical conductors, and a hose connector at each end of said hose assembly, one of said connectors providing mechanical and electrical continuity between said hose and said vacuum cleaner;

the improvement wherein said adapter is separate from said hose assembly and comprises electrical control means for controlling said vacuum cleaning system, and means interlocking said adapter with the other of said hose connectors and providing for repeated connection and disconnection therewith and electrical continuity from said electrical control means through said hose assembly to said vacuum cleaner.

2. The system of claim 1 wherein said control means comprises an on-off switch for said cleaning tool.

3. The system of claim 2 wherein said control means further comprises means being sensitive to and serving to detect practically every type of fault capable of causing injury to humans and operating to interrupt said electrical continuity upon detection of a fault.

4. The system of claim 1 wherein said control means comprises an on-off switch for said vacuum cleaner.

5. The system of claim 1 wherein said control means comprises on-off switch means for said cleaning tool and said vacuum cleaner.

6. The system of claim 5 wherein said control means further comprises means being sensitive to and serving to detect practically every type of fault capable of causing injury to humans and operating to interrupt said electrical continuity upon detection of a fault, said fault detecting means being located in electrical circuits to both said cleaning tool and said vacuum cleaner.

7. In a connect-disconnect hose and cleaning tool adapter assembly for a vacuum cleaning system including a vacuum cleaner, said assembly comprising a hose and an adapter;

the improvement wherein said adapter is separate from said hose and comprises electrical control means incorporated therein for controlling said system, and means providing for repeated connection and disconnection of said adapter to said hose and providing electrical continuity therebetween.

8. The assembly of claim 7 wherein said control means comprises an on-off switch for said cleaning tool.

9. The assembly of claim 8 wherein said control means further comprises means being sensitive to and serving to detect practically every type of fault capable of causing injury to humans and operating to interrupt said electrical continuity upon detection of a fault.

10. The assembly of claim 7 wherein said control means comprises an on-off switch for said vacuum cleaner.

11. The assembly of claim 7 wherein said control means comprises on-off switch means for said cleaning tool and said vacuum cleaner.

12. The assembly of claim 7 wherein said adapter includes means for mechanically interconnecting to a cleaning tool, and separate means for providing electrical continuity thereto.

13. In a vacuum cleaning tool adapter for a vacuum cleaning system including a vacuum cleaner and a hose assembly;

the improvement wherein said adapter is separate from said hose assembly and comprises electrical control means for controlling said system, and repeated connecting and disconnecting means for mechanically interlocking said adpater to said hose assembly and providing electrical continuity thereto.

14. The adapter of claim 13 wherein said control means comprises an on-off switch for said cleaning tool.

15. The adapter of claim 14 wherein said control means further comprises means being sensitive to and serving to detect practically every type of fault capable of causing injury to humans and operating to interrupt said electrical continuity upon detection of a fault.

16. The adapter of claim 13 wherein said control means comprises an on-off switch for said vacuum cleaner.

17. The adapter of claim 13 wherein said control means comprises on-off switch means for said cleaning tool and said vacuum cleaner.

18. The adapter of claim 17 wherein said control means further comprises means being sensitive to and serving to detect practically every type of fault capable of causing injury to humans and operating to interrupt said electrical continuity upon detection of a fault, said fault detecting means being located in electrical circuits to both said cleaning tool and said vacuum cleaner.

19. The adapter of claim 13 wherein said adapter includes means for mechanically interconnecting to a cleaning tool, and separate means for providing electrical continuity thereto.

20. The adapter of claim 13 comprising a body and an air-conducting member mechanically interengaged with said body, said electrical control means and said mechanically interlocking means incorporated within said body.

21. The adapter of claim 20 wherein said means providing electrical continuity to said hose assembly are also incorporated within said body.

22. The adapter of claim 20 further comprising means providing electrical continuity to a cleaning tool, said means also incorporated within said body.

23. The adapter of claim 22 wherein said adapter includes means for mechanically interconnecting to said cleaning tool.

24. The adapter of claim 20 wherein said body is made of a polymeric material.

25. The adapter of claim 24 wherein said air-conducting member is incorporated into said body.

26. The adapter of claim 20 wherein said adapter further comprises means for providing electrical continuity to a cleaning tool;

said electrical control means, said means for interlocking said adapter to said hose assembly, and said means for providing electrical continuity to said cleaning tool, all incorporated within said body.

27. The adapter of claim 26 wherein said means for interlocking said adapter to said hose assembly is located at one end of said adapter, and said means for providing electrical continuity to said cleaning tool is located at the opposite end of said adapter.
