Combined plunger and scrub brush

Abstract

The combined plunger and scrub brush device comprises a hollow cylinder connected to a plunger with an elongate handle rod or shaft movably received in the hollow cylinder and having a scrub brush mounted to a lower end of the handle rod or shaft, the plunger cup having a closing flap connected by a living hinge to the plunger cup and positioned to cover a lower opening of the hollow cylinder when the scrub brush is moved from a lowered scrubbing position upwardly to a closed position in the hollow cylinder above the closing flap. The hollow cylinder mounts a locking ring having a protrusion extending radially inwardly therefrom for being received in a slot or in one of two notches or in a notch in a disk body fixed to the handle shaft for locking the handle shaft in a lower scrubbing position or in the retracted upper closed position.

1 . A combined plunger and scrub brush device comprising a hollow cylinder connected to a plunger cup with an elongate handle rod or shaft movably received in the hollow cylinder and having a scrub brush mounted to a lower end of the handle rod or shaft, said plunger cup having a closing flap connected by a living hinge to the plunger cup and positioned to cover a lower opening in the hollow cylindrical body portion when the scrub brush is moved from a lowered scrubbing position upwardly to a closed position in the hollow cylindrical body portion above the closing flap. 
     
     
         2 . The combined plunger and scrub brush device of  claim 1  wherein said hollow cylindrical body portion mounts a locking ring having a protrusion extending radially inwardly therefrom for being received in a notch in or in an axially extending slot in a shaft assembly for locking the scrub brush in an upper retracted position. 
     
     
         3 . The combined plunger and scrub brush device of  claim 1  wherein said hollow cylindrical body portion mounts a locking ring having a protrusion extending radially inwardly therefrom for being received in a notch in or an axially extending slot in a shaft assembly for locking the scrub brush in a lower scrubbing position. 
     
     
         4 . The combined plunger and scrub brush device of  claim 1  wherein said scrub brush is releasably mounted to the lower end of said handle rod or shaft to facilitate replacement of said brush.
