Abstract
A ratchet-like coupling mechanism ( ) for releaseably coupling a cleaning head ( ) to a handle ( ). The mechanism ( ) comprises a handle adaptor ( ); a sleeve ( ); an engagement arm ( ); and an engagement wheel ( ). Where a liquid delivering handle ( ) is used, the handle adaptor ( ) operates to adapt the mechanism ( ) to avoid interfering with the liquid flowpath. The handle adaptor ( ) may be eliminated where a solid handle is used. The sleeve ( ) secures to the handle adaptor ( ) or directly to the handle, and supports the engagement arm ( ). The engagement wheel ( ) is secured to the head ( ). The arm ( ) and wheel ( ) present oppositely biased teeth ( ) allowing the adaptor ( ) or handle to be threadably coupled with the head ( ), but which must be disengaged, by actuating the arm ( ), to uncouple the head ( ) from the handle ( ).
