Electrified extension hose for vacuum cleaner

Abstract

An electrical extension hose includes a flexible hose body having first and second ends. A first electrified coupler is provided at the first end. A second electrified coupler is provided at the second end. At least two electrical conductors interconnect the first and second couplers. Further, the first and second couplers are capable of mating interconnection. Thus any number of electrical extension hoses may be connected together to construct a working hose of desired length.

1 . A electrified extension hose, comprising: 
 a flexible hose body having a first end and a second end;    a first coupler on said first end of said hose body;    a second coupler on said second end of said hose body;    a first electrical terminal and a second electrical terminal on said first coupler;    a third electrical terminal and a fourth electrical terminal on said second coupler;    a first electrical conductor carried on said hose body and connecting said first and third electrical terminals;    a second electrical conductor carried on said hose body and connecting said second and fourth electrical terminals; and    said electrified extension hose being characterized by at least one of said first and second couplers being capable of mating with a corresponding electrical coupler on another hose.    
   
   
       2 . The electrified extension hose of  claim 1  wherein said hose body defines a lumen and includes a reinforcing wire and a collapsible wall.  
   
   
       3 . The electrified extension hose of  claim 1 , wherein said first coupler carries a first connector and said second coupler carries a second connector.  
   
   
       4 . The electrified extension hose of  claim 3 , wherein said first and second connectors are cooperating male and female connectors that secure two like hoses together.  
   
   
       5 . An electrical extension hose, comprising: 
 a flexible hose body having a first end and a second end;    a first electrified coupler at said first end;    a second electrified coupler at said second end; and    at least two electrical conductors interconnecting said first and second electrified couplers;    said first and second electrified couplers being capable of mating interconnection.
