Upright vacuum cleaner incorporating telescopic wand assembly with trigger operation

Abstract

An upright vacuum cleaner includes a housing having a nozzle assembly and a canister assembly. A suction generator and a dirt collection vessel are both carried on the housing. The vacuum cleaner also includes a detachable telescopic wand assembly. That wand assembly includes a first wand section, a second wand section, a wand lock for securing the two wand sections together and a trigger actuator for operating the wand lock. The trigger actuator is located remote from the wand lock on the wand assembly.

1 . An upright vacuum cleaner, comprising: 
 a housing including a nozzle assembly and a canister assembly;    a suction generator carried on said housing;    a dirt collection vessel carried on said housing;    a detachable telescopic wand assembly including a first wand section, a second wand section, a wand lock for securing said first and second wand sections together and a trigger actuator for operating said wand lock, said trigger actuator being located remote from said wand lock on said wand assembly.    
   
   
       2 . The upright vacuum cleaner of  claim 1 , further including a linkage connecting said trigger actuator to said wand lock.  
   
   
       3 . The upright vacuum cleaner of  claim 2 , wherein said linkage includes a crank and a link arm.  
   
   
       4 . The upright vacuum cleaner of  claim 3 , wherein said crank is pivotally connected to said wand assembly.  
   
   
       5 . The upright vacuum cleaner of  claim 4 , wherein said crank includes a first end connected to said trigger actuator and a second end connected to said link arm.  
   
   
       6 . The upright vacuum cleaner of  claim 5 , wherein a first end of said link arm is connected to said crank and a second end of said link arm is connected to said wand lock.  
   
   
       7 . The upright vacuum cleaner of  claim 5 , wherein said crank includes a hub between said first end and said second end.  
   
   
       8 . The upright vacuum cleaner of  claim 7 , wherein a pivot pin is received in said hub, said pivot pin pivotally connecting said crank to said wand assembly.  
   
   
       9 . The upright vacuum cleaner of  claim 6 , wherein said wand lock includes a sliding actuator, a biasing spring and a locking pin and said second wand section includes a series of spaced notches, said locking pin being selectively received in one of said notches in order to secure said first wand section relative to said second wand section.  
   
   
       10 . The upright vacuum cleaner of  claim 1 , wherein said wand assembly further includes a control handle.  
   
   
       11 . The upright vacuum cleaner of  claim 10 , wherein said control handle includes a hand grip.  
   
   
       12 . The upright vacuum cleaner of  claim 1   1 , wherein said trigger actuator is carried on said control handle adjacent said hand grip.  
   
   
       13 . The upright vacuum cleaner of  claim 1 , wherein said nozzle assembly and said canister assembly are pivotally connected together.  
   
   
       14 . The upright vacuum cleaner of  claim 1 , wherein said dirt collection vessel is a filter bag.  
   
   
       15 . The upright vacuum cleaner of  claim 1 , wherein said dirt collection vessel is a dirt cup.  
   
   
       16 . The upright vacuum cleaner of  claim 15 , wherein said dirt cup is substantially cylindrical in shape and includes a tangentially directed inlet.  
   
   
       17 . The upright vacuum cleaner of  claim 16 , wherein said dirt cup carries a filter.  
   
   
       18 . The upright vacuum cleaner of  claim 15 , wherein said dirt cup carries a filter.  
   
   
       19 . The upright vacuum cleaner of  claim 1 , further including a final filter downstream from said suction generator.  
   
   
       20 . A method for manufacturing a telescopic wand including a first wand section, a second wand section, a wand lock and a control handle, comprising: 
 providing said control handle adjacent a first end of said first wand section;    providing said wand lock adjacent a second end of said first wand section; and    providing a control trigger for said wand lock adjacent said control handle and remote from said wand lock.
