Low-profile Drain

Abstract

A low-profile drain includes a drain body configured to direct liquids into a drainage system, the drain body having an upper barrel and a lower barrel. A flange extends outwardly from the upper barrel of the drain body. A bondable waterproof membrane is attached to an upper surface of the flange and extending outwardly away from the flange. A bonding fleece is attached to a lower surface of the flange.

1 . A low-profile drain, comprising:
 a drain body configured to direct liquids into a drainage system, the drain body having an upper barrel and a lower barrel;   a flange extending outwardly from the upper barrel of the drain body, the flange extending outwardly from the drain body in a substantially flat plane so as to be configured to lie flat against a surrounding flat subfloor surface; and   a bondable waterproof membrane attached to an upper surface of the flange and extending outwardly away from the flange.   
     
     
         2 . The drain of  claim 1 , further comprising a bonding fleece attached to a lower surface of the flange. 
     
     
         3 . The drain of  claim 1 , wherein each of the flange, the bondable waterproof membrane and the bonding fleece having a thickness, and wherein a combined thickness of the flange, the bondable waterproof membrane and the bonding fleece is less than about 0.25 inches above the surrounding flat subfloor. 
     
     
         4 . The drain of  claim 1 , wherein the flange extends outwardly from the upper barrel of the drain body in a first axis and a second axis, the second axis orthogonal to the first axis, and wherein a distance the flange extends in the first axis is substantially equal to a distance the flange extends in the second axis. 
     
     
         5 . The drain of  claim 4 , wherein the bondable waterproof membrane extends outwardly from the flange in the first axis and the second axis, and wherein a distance the bondable waterproof membrane extends in the first axis is substantially equal to a distance the bondable waterproof membrane extends in the second axis. 
     
     
         6 . The drain of  claim 1 , wherein the flange terminates in at least one flange edge, the at least one flange edge being planar. 
     
     
         7 . The drain of  claim 1 , wherein the flange extends from the drain body at an angle relative to a center vertical axis of the drain body, the angle being between about 90 degrees and about 95 degrees. 
     
     
         8 . The drain of  claim 7 , wherein angle is about 90 degrees. 
     
     
         9 . The drain of  claim 1 , wherein the drain body and flange are formed of a unitary piece of a polymeric material. 
     
     
         10 . The drain of  claim 1 , wherein bonding fleece substantially completely covers the lower surface of the flange. 
     
     
         11 . A low-profile drain, comprising:
 a drain body configured to direct liquids into a drainage system, the drain body having an upper barrel and a lower barrel;   a flange extending outwardly from the upper barrel of the drain body;   a bondable waterproof membrane attached to an upper surface of the flange and extending outward away from the flange, the bondable waterproof membrane being foldable inwardly over the drain body; and   a bonding fleece attached to a lower surface of the flange;   the flange extending outwardly from the drain body in a substantially flat plane so as to be configured to lie flat against a surrounding flat subfloor surface.   
     
     
         12 . The drain of  claim 11 , wherein the flange extends outwardly from the upper barrel of the drain body in a first axis and a second axis, the second axis orthogonal to the first axis, and wherein a distance the flange extends in the first axis is substantially equal to a distance the flange extends in the second axis. 
     
     
         13 . The drain of  claim 11 , wherein the bondable waterproof membrane extends outwardly from the flange in the first axis and the second axis, and wherein a distance the bondable waterproof membrane extends in the first axis is substantially equal to a distance the bondable waterproof membrane extends in the second axis. 
     
     
         14 . The drain of  claim 11 , wherein the flange terminates in at least one flange edge, the at least one flange edge being planar. 
     
     
         15 . The drain of  claim 11 , wherein the flange extends from the drain body at an angle relative to a center vertical axis of the drain body, the angle being between about 90 degrees and about 95 degrees. 
     
     
         16 . The drain of  claim 15 , wherein angle is about 90 degrees. 
     
     
         17 . The drain of  claim 11 , wherein the drain body and flange are formed of a polymeric material. 
     
     
         18 . A low-profile drain, comprising:
 a drain body configured to direct liquids into a drainage system, the drain body having an upper barrel and a lower barrel;   a flange extending outwardly from the upper barrel of the drain body;   a bondable waterproof membrane attached to an upper surface of the flange and extending outward away from the flange; and   a bonding fleece attached to a lower surface of the flange;   the flange terminating in four planar edges and extending outwardly from the drain body in a substantially flat plane so as to be configured to lie flat against a surrounding subfloor surface.   
     
     
         19 . The drain of  claim 18 , wherein the bondable waterproof membrane terminates in four planar edges.
