Hand wand with electrical wiring for vacuum cleaning

Abstract

A hand held wand for connecting an electrically powered cleaning device to a source of vacuum and electricity has inner and outer concentrically mounted tubular members which form an intervening passage therebetween. An electrical conductor extends through the passage and terminates in a pair of electrical connectors mounted on a pair of end connector sleeves. The inner and outer tubular members terminate in the end connector sleeves. One of the end connector sleeves is adapted to be connected to the cleaning device and the other connector sleeve is connected to a flexible hose which is connected to the source of vacuum. The electrical connectors are connected to complementary electrical connectors mounted on the cleaning device and on the flexible hose to provide electric power to the cleaning device.

What is claimed:  
     
         1 . A hand wand for connecting an electrically powered cleaning device to a source of electricity and to a source of vacuum comprising: 
 inner and outer tubular members extending between a pair of end connector sleeves, said tubular members forming a passage therebetween;    an electrical conductor extending through the passage between the tubular members; and    an electrical connector mounted adjacent each of the connector sleeves and electrically connected to the electrical conductor.    
     
     
         2 . The wand defined in  claim 1  wherein the passage is an annular space formed between the inner and outer tubular members.  
     
     
         3 . The wand defined in  claim 1  wherein the inner and outer tubular members are formed of metal or plastic.  
     
     
         4 . The wand defined in  claim 1  wherein one of the electrical connectors is a male connector and the other of said connectors is a female connector.  
     
     
         5 . The wand defined in  claim 1  wherein a flexible hose containing an electrical conductor for connecting the wand to the source of vacuum is connected to one of the end connector sleeves.  
     
     
         6 . The wand defined in  claim 5  wherein the cleaning device is connected to the other of the connector sleeves.  
     
     
         7 . The wand defined in  claim 6  wherein the hose and cleaning device are connected to the connector sleeves by a friction slide fit engagement.  
     
     
         8 . The wand defined in  claim 6  wherein the hose and cleaning device are connected by a latch.  
     
     
         9 . In combination, a source of vacuum and electrical power, an electrically driven cleaning device and a wand for connecting said cleaning device to the source of vacuum and electrical power, said wand comprising: 
 inner and outer tubular members extending between a pair of end connector sleeves, said tubular members forming a passage therebetween;    an electrical conductor extending through the passage between the tubular members; and    an electrical connector mounted adjacent each of the connector sleeves and electrically connected to the electrical conductor.    
     
     
         10 . The combination defined in  claim 9  wherein a flexible hose extends between the wand and source of vacuum.  
     
     
         11 . The combination defined in  claim 9  wherein the passage is an annular space formed between the inner and outer tubular members.  
     
     
         12 . The combination defined in  claim 9  wherein the inner and outer tubular members are formed of metal or plastic.  
     
     
         13 . The combination defined in  claim 9  wherein a flexible hose containing an electrical conductor for connecting the wand to the source of vacuum is connected to one of the end connector sleeves.  
     
     
         14 . The combination defined in  claim 13  wherein the cleaning device is connected to the other of the connector sleeves.  
     
     
         15 . The combination defined in  claim 9  wherein the source of vacuum is a portable vacuum cleaner.
