Bath drain closure assembly

Abstract

A drain closure assembly for use with a bathtub, having a drain closure device with a stopper positioned above a lower drain and a plunger device attached to the stopper adapted to bias the stopper in a downward direction. An actuating mechanism received within a housing in communication with a conduit extending from the lower drain, the actuating member having a main body that contacts the drain closure device and moves the drain closure device to an open position when activated and a closed position when deactivated.

1 . A bath drain closure assembly for a bathtub having a drain port in fluid communication with a conduit, comprising: 
 a drain closure device mounted to and extending through the drain port;    a movable actuating member that engages the drain closure device such that the drain closure device is moved to an open position when the actuating member is activated by an electrical charge and the closure device is moved to a closed position when the actuating member is deactivated; and    a housing for slidably receiving the actuating member, wherein the housing is joined to and in fluid communication with the conduit.    
   
   
       2 . The assembly of  claim 1 , wherein the actuating member is a solenoid piston.  
   
   
       3 . The assembly of  claim 2 , wherein the solenoid piston comprises a main body received by the housing, and a coil mounted to the exterior of the housing and exterior to the conduit.  
   
   
       4 . The assembly of  claim 3  further comprising an electrical contact coupling the coil to an activation switch, wherein the electrical contact is exterior to the housing and the conduit.
