Plumbing plunger

Abstract

A high powered blast or suction of fast moving water to remove solid blockage or obstructions from within sink, bathtub, shower, and toilet bowl drain pipes uses a piston mounted within a cylinder with specifically designed interchangeable rubber plunger tips connected to the end of the piston powered manual water pumping plunger. The present invention provides a high powered blast or suction of fast moving water to remove solid blockage or obstructions from within sink, bathtub, shower, and toilet bowl drain pipes using specifically designed interchangeable rubber plunger tips and a piston powered manual water pumping plunger.

1 . A plumbing plunger system comprising:
 a plunger cylinder body;   a plurality of sealing members each arranged to be separately mounted on a bottom end of the cylinder body with the others of the sealing members removed;   each sealing member being shaped and arranged to engage or penetrate a drain hole of a plumbing device including a toilet, sink, shower drain, tub drain and floor drain;   a double acting piston mounted in the cylinder and connected to a shaft having a handle at an upper end of the cylinder for manual movement of the piston within the cylinder:   the sealing members each having an opening therethrough such that operation of the piston by the handle moves water between the drain hole and the cylinder for pumping water into the drain hole or extracting water from the drain hole.   
   
   
       2 . The plunger according to  claim 1  wherein the shaft and handle are arranged such that the piston reaches the sealing member at the bottom of the body when fully inserted. 
   
   
       3 . The plunger according to  claim 1  wherein each of the sealing members provides a stop surface for engaging and halting movement of the piston. 
   
   
       4 . The plunger according to  claim 1  wherein the cylinder has a discharge opening above the piston for discharge of air and any water collecting above the piston, the discharge opening including a down-turned nozzle for guiding any discharge water down toward the drain hole. 
   
   
       5 . The plunger according to  claim 1  wherein the piston includes top and bottom conical sealing surfaces tapering outwardly to respective top and bottom edges for sealing in both directions. 
   
   
       6 . The plunger according to  claim 1  wherein one of the sealing members comprises a cylinder portion with a bottom wall defining by an in-turned lip so as to form a sealing ring for surrounding the drain hole. 
   
   
       7 . The plunger according to  claim 1  wherein at least one of the sealing members includes a generally conical wall extending downwardly from a sealing ring. 
   
   
       8 . The plunger according to  claim 1  wherein one of the sealing members includes a tube extending downwardly from a bottom wall of the sealing member which tube is offset to one side from a central axis of the cylinder. 
   
   
       9 . The plunger according to  claim 8  wherein the tube has a bottom edge lying in a plane at an angle to a radial plane of the axis. 
   
   
       10 . The plunger according to  claim 8  wherein there is provided an insert portion for engaging into the tube which has a pipe extending from the insert portion. 
   
   
       11 . The plunger according to  claim 1  wherein one of the sealing members includes downwardly extending duct portion and a flange lying in a plane generally at right angles to the axis and projecting to one side of the sealing member at a position above a bottom end of the duct portion for covering a channel at the drain of the toilet bowl with the duct portion extending into the drain of the toilet bowl. 
   
   
       12 . The plunger according to  claim 1  wherein one of the sealing members includes a converging neck portion and an extension tube extending from a bottom of the neck portion generally at right angles to the axis for insertion into a pipe. 
   
   
       13 . The plunger according to  claim 12  wherein the extension tube is flexible. 
   
   
       14 . The plunger according to  claim 1  wherein each of the sealing members is arranged to be readily fastened onto and removed from the end of the cylinder. 
   
   
       15 . The plunger according to  claim 1  wherein the sealing members are injection molded in a common family mold. 
   
   
       16 . The plunger according to  claim 1  wherein piston includes a sleeve mounted on an end of a plunger rod with a plurality of angularly spaced gussets connecting between the sleeve and an annular band forming the piston. 
   
   
       17 . A plumbing plunger system comprising:
 a plunger cylinder body;   a plurality of sealing members each arranged to be separately mounted on a bottom end of the cylinder body with the others of the sealing members removed;   a double acting piston mounted in the cylinder and connected to a shaft having a handle at an upper end of the cylinder for manual movement of the piston within the cylinder:   the sealing members each having an opening therethrough such that operation of the piston by the handle moves water between the drain hole and the cylinder for pumping water into the drain hole or extracting water from the drain hole;   a first one of the sealing members comprising a cylinder portion with a bottom wall defining by an in-turned lip so as to form a sealing ring for surrounding the drain hole;   a second one of the sealing members comprising an upper sealing ring and a generally conical wall extending downwardly from a sealing ring coaxial to the cylindrical body.   a third one of the sealing members comprising a cylindrical portion with a transverse bottom wall and a tube extending downwardly from the bottom wall of the sealing member which tube is offset to one side from a central axis of the cylinder.   
   
   
       18 . The plunger according to  claim 17  wherein there is provided an insert portion for engaging into the tube of the third sealing member which has a pipe extending from the insert portion. 
   
   
       19 . The plunger according to  claim 17  wherein there is provided a fourth one of the sealing members which includes downwardly extending duct portion and a flange lying in a plane generally at right angles to the axis and projecting to one side of the sealing member at a position above a bottom end of the duct portion for covering a channel at the drain of the toilet bowl with the duct portion extending into the drain of the toilet bowl. 
   
   
       20 . The plunger according to  claim 17  wherein there is provided a fifth one of the sealing members which includes a converging neck portion and an extension tube extending from a bottom of the neck portion generally at right angles to the axis for insertion into a pipe.
