Drain assembly for rapid installation in sanitary vessels

An improved sanitary drain assembly, comprising:

• a drain stopper assembly having a multi-piece housing with a longitudinal axis;
• said housing including a proximate extent for disposal proximate a vessel surface, at which proximate extent a flange portion is provided with a fluid egress for delivery of fluid therethrough;
• said housing further including an opposing distal extent at which a fluid conduit is provided for delivery of said fluid from said drain assembly;
• said housing also including a drain body having a lumen within which a drain insert portion thereof accommodates a reciprocatable stopper thereby, said stopper having a closure head from which an elongate shaft depends generally normally and which obstructs said fluid egress when said stopper is in a closed position, said shaft having a proximate extent adjacent said closure head and an opposing free extent disposed in said drain insert when said stopper is in a closed position;
• wherein said drain body has each of an inner circumferential surface of predetermined inner diameter and an outer circumferential surface of predetermined outer diameter, said drain body further including a securement region positioned along said outer circumferential surface thereof, and terminating in a distal extent;
• and an actuation assembly having a motion translation device in communication with a drain articulation device, said securement region effecting operational communication between said drain stopper assembly and said actuation assembly so that operation of said drain articulation member effects reciprocal motion of said drain stopper;
• wherein said distal extent of said securement region does not extend beyond said predetermined outer diameter of said housing outer surface.

An improved sink drain assembly, comprising:

• a drain stopper assembly having:
• an elongate housing with a longitudinal axis defined therealong, said housing including a proximate extent for disposal proximate a vessel surface, an opposing distal extent for disposal proximate a waste outlet and a longitudinal body coextensive extent with said proximate and distal extents and defining a lumen therein, said body having each of an inner circumferential surface of predetermined inner diameter and an outer circumferential surface of predetermined outer diameter;
• said housing further including a flange portion at said proximate extent wherein said flange portion has a fluid egress for delivery of fluids from said sanitary vessel to said housing lumen;
• a linearly reciprocable drain stopper having a closure head from which an elongate shaft depends generally normally so that a longitudinal axis thereof is coincident with said housing longitudinal axis, said shaft having a proximate extent adjacent said closure head and an opposing free extent disposed in said housing lumen, wherein said stopper has a fully closed position wherein said closure head obstructs said fluid egress and a fully open position wherein said fluid egress remains unobstructed;
• and
• a securement region provided on said outer housing surface along said longitudinal body thereof and having a receiving region defined therewith;
• and an actuation assembly detachably couplable with said securement region so as to effect operational communication between said drain stopper assembly and said actuation assembly upon operation of a drain articulation device and correspondingly effect reciprocal motion of said drain stopper;
• said actuation assembly comprising:
• a motion translation device in communication with a drain articulation member;
• and
• a motion transfer mechanism that facilitates operative communication between said motion translation device and said drain stopper assembly.
