Abstract
The present invention provides an improved drain assembly having a drain stopper assembly in operational communication with an actuation assembly. The drain stopper assembly includes an elongate one-piece housing with a longitudinal body coextensive with proximal and distal extents of the housing and defining a lumen therein. A flange portion at the proximal extent has a fluid egress for delivery of fluids from a sanitary vessel to the housing lumen. The housing body has an inner circumferential surface of predetermined inner diameter and an outer circumferential surface of predetermined outer diameter. A linearly reciprocatable drain stopper is provided that has a closure head proximate which an elongate shaft depends. The stopper reciprocates between a fully closed position, wherein the closure head obstructs the fluid egress, and a fully open position, wherein the fluid egress remains unobstructed. A securement region provided on the outer housing surface has a receiving region defined therewith and effects operational communication between the drain stopper assembly and the actuation assembly so that operation of a drain articulation member effects reciprocal motion of the drai…
