Flushing device for toilets

Abstract

A flushing device for toilets includes a source for applying a fluid pressure to a blockage area and provides a seal in the blocked conduit to prevent backflow so that full pressure is applied to the blockage. The device includes a resilient deformable and inflatable element secured at the end of a tubular handle which is inserted into a toilet conduit leading to the drain line. The tubular handle has a coupling at its end opposite to the end carrying the inflatable element to which a hose is connected in order to supply pressurized water to the element. The inflatable element is carried on a linear portion of the tubular handle adjacent to the discharge orifice thereof and is expanded by inflation into a sealing condition with the conduit entrance leading into the drain line. The exterior surface of the inflatable element is provided with spaced-apart ridges and grooves that are deformable to provide a positive sealing relationship with the entrance of the conduit so as to completely seal the entrance.

What is claimed is:  
     
         1 . Blockage clearance device for a toilet conduit comprising: 
 an elongated tube having opposite ends disposed between a passageway;    an expandable element secured to a selected end of said tube and having an internal cavity;    inflation means detachably coupled with the other end of said tube and in fluid communication with said internal cavity;    a first source of pressurized fluid including said inflation means in communication with said internal cavity for introducing a pressurized fluid to said expandable element;    said expandable element adapted to radially expand to close and seal with a toilet drainage conduit in response to introduction of said pressurized fluid; and    a second source of pressurized fluid detachably coupled with the other end of said tube for supplying a second pressurized fluid to flow through said passageway to forcibly clear said toilet drainage conduit.    
     
     
         2 . The clearance device defined in  claim 1  wherein: 
 said expandable element includes an outer exterior surface carrying a plurality of spaced-apart ribs deformable upon compression to provide a sealing relationship with said toilet drainage conduit.  
 
     
     
         3 . The clearance device defined in  claim 2  wherein: 
 said selected end of said tube having an outwardly projecting sleeve supporting and mounting said expandable element.  
 
     
     
         4 . The clearance device defined in  claim 3  wherein: 
 said expandable element includes a pair of end members of a given thickness and a cylindrical membrane joining said end member about said internal cavity and said membrane composed of a pliable material substantially thinner than said given thickness of said end members.  
 
     
     
         5 . The clearance device defined in  claim 4  wherein: 
 said inflation means includes the selection of: 
 a. hand pump,  
 b. air gun,  
 c. manual foot pedal.  
 
 
     
     
         6 . The clearance device defined in  claim 4  wherein: 
 said inflation means includes a pipe having a pair of ends with one end terminating with said internal cavity and the other end connected with said first source of pressurized fluid.  
 
     
     
         7 . The clearance device defined in  claim 6  including: 
 a cushion grip carried on an external surface of said tube.  
 
     
     
         8 . The clearance device defined in  claim 7  wherein: 
 said first and said second source of pressurized fluid being coupled together to provide a unitary construction.  
 
     
     
         9 . In a pipe or drain opener of the type comprising a rubberized expandable member having a cylindrical flexible element with an edged shape exterior surface forcibly engagable with an inner surface of said pipe or drain; 
 an elongated handle extending from said expandable member to an opposite end connected with an inflation source; and    said handle having an air passage therethrough.
