Abstract

A drain assembly includes a drain body, barrel, plug, and gasket. The drain body has an interior surface defining a channel along an axis and having interior threads thereon. The barrel has a central body having an upper end, with a flange extending radially outward therefrom and defining a landing surface. The central body has opposed exterior and interior barrel surfaces having exterior and interior threads, respectively. The interior barrel surface defines a channel alignable with the axis. The exterior threads are engageable with the drain body interior threads for axially adjusting the barrel relative to the drain body. The plug has a top wall and an outer body extending axially downward therefrom to a stop surface. A portion of the outer body extends axially below the stop surface and has external threads engageable with the barrel interior threads. The gasket is sealingly receivable between the stop and landing surfaces.

First claim

What is claimed is:

1. A drain assembly, comprising:
a drain body defining an interior drain surface that defines a drain channel extending along a central axis, wherein an upper receptacle portion of the interior drain surface defines interior threads;
an upper barrel having a central body and a flange extending radially outward from an upper end of the central body, the flange defining a landing surface, the central body having an exterior barrel surface opposite an interior barrel surface, the interior barrel surface defining a barrel channel alignable with the central axis of the drain body, the central body having interior threads formed on the interior barrel surface and exterior threads formed on the exterior barrel surface adjacent to a lower end thereof, the exterior threads being engageable with the interior threads of the drain body, wherein the upper barrel is axially adjustable relative to the drain body along the central axis;
a plug having a top wall, an outer body extending axially downward from the top wall, the outer body defining a stop surface opposite the top wall, the outer body including an inner portion extending axially below the stop surface, the inner portion having external threads engageable with the interior threads of the upper barrel; and
a plug gasket axially receivable between the stop surface of the plug and the landing surface of the upper barrel, wherein the plug gasket is abuttable with the stop surface and the landing surface to provide a seal therebetween.

2. The drain assembly of claim 1 , wherein the external threads of the plug are removably engageable with the interior threads of the upper barrel, such that the plug is removably attachable to the upper barrel during a pre-pour phase of drain assembly.

3. The drain assembly of claim 1 , wherein the outer body of the plug defines an exterior plug surface, and the exterior plug surface is engageable with cement during a cement pouring phase of drain assembly.

4. The drain assembly of claim 3 , wherein the plug is constructed of a material for providing a non-binding contact interface between the exterior plug surface and the cement.

5. The drain assembly of claim 4 , wherein the material comprises acetal plastic.

6. The drain assembly of claim 3 , wherein the exterior plug surface is coated with a layer of coating material configured to provide a non-binding contact interface with the cement.

7. The drain assembly of claim 6 , wherein the coating material is selected from the group comprising polyvinyl alcohol, mineral oil, silicone, polysiloxane, wax, and polytetrafluoroethylene (PTFE).

8. The drain assembly of claim 3 , wherein the plug is interchangeable with a strainer barrel, the strainer barrel having a central body insertable within the barrel channel, the central body of the strainer barrel having an exterior surface opposite an interior surface, the interior surface of the strainer barrel defining a strainer barrel channel alignable with the central axis of the drain body, wherein the exterior surface of the central body of the strainer barrel has exterior threads engageable with the interior threads on the interior barrel surface, and wherein the strainer barrel is axially adjustable relative to the upper barrel.

9. The drain assembly of claim 8 , wherein, in a first operative configuration of the drain assembly, the plug is fully seated within the barrel channel, a top surface of the top wall of the plug is spaced upwardly from the landing surface of the upper barrel at a first distance along an axial direction that is parallel with the central axis.

10. The drain assembly of claim 9 , further comprising a drain grate attachable to a top end of the strainer barrel, wherein, when the drain grate is attached to the strainer barrel and the strainer barrel is attached to the upper barrel, a top surface of the drain grate is spaced upwardly from the landing surface of the upper barrel at a second distance along the axial direction, wherein the second distance is less than the first distance.

11. The drain assembly of claim 10 , wherein, in a second operative configuration of the drain assembly, a relative position between the drain body and the upper barrel is rigidly fixed, such that the strainer barrel being axially adjustable relative to the upper barrel causes the second distance to be adjustable while the landing surface of the upper barrel has a fixed position relative to the drain body.

12. A drain assembly, comprising:
a drain body defining an interior drain surface that defines a drain channel extending along a central axis, wherein the interior drain surface extends between an upper end of the drain body and a lower end of the drain body, the drain body defining an upper mounting surface at the upper end;
a flange body attachable to the upper mounting surface of the drain body, the flange body having an interior circumferential edge that defines a flange channel alignable with the central axis of the drain body, the flange body having a top end and a bottom end opposite the top end, the flange body having a flange member that has an outer circumferential edge spaced radially outward from the interior circumferential edge,
wherein the interior drain surface and the interior circumferential edge are sized for receiving a central body of an upper barrel therein while the flange body is attached to the upper mounting surface of the drain body.

13. The drain assembly of claim 12 , further comprising a flange gasket receivable between the flange body and the upper mounting surface of the drain body.

14. The drain assembly of claim 13 , wherein the flange body includes a lower mounting portion at the bottom end and a tubular riser portion extending axially upwardly from the lower mounting portion, the flange member extends radially outward from the tubular riser portion to the outer circumferential edge, the lower mounting portion has a lower mounting surface configured to face the upper mounting surface of the drain body, and the flange gasket is retainable between the upper and lower mounting surfaces.

15. The drain assembly of claim 14 , wherein the upper mounting surface of the drain body defines a first plurality of holes, the flange gasket defines a second plurality of holes, and the lower mounting portion defines a third plurality of holes, and at least some of each of the first, second, and third pluralities of holes are axially alignable with each other.

16. The drain assembly of claim 15 , further comprising a plurality of screws insertable through the axially alignable holes of the first, second, and third pluralities of holes for affixing the flange body and the flange gasket to the upper mounting surface of the drain body.

17. The drain assembly of claim 13 , further comprising a collar body receivable between the flange member and the flange gasket, the collar body having an upper collar surface and an opposed lower collar surface, wherein the upper collar surface is abuttable with a bottom surface of the flange member, the lower collar surface is abuttable with an upper surface of the flange gasket, and a lower surface of the flange gasket is abuttable with the upper mounting surface of the drain body.

18. The drain assembly of claim 17 , wherein the upper mounting surface of the drain body defines a first plurality of holes, the flange gasket defines a second plurality of holes, and the collar body defines a third plurality of holes, and at least some of each of the first, second, and third pluralities of holes are axially alignable with each other.
