Abstract

A drain assembly for providing a drain in a floor. The drain assembly includes a drain conduit, a strainer and an adaptor. The drain conduit has an inner surface that defines a fluid flow path and an outer surface. The strainer is disposed above the drain conduit and has openings in fluid communication with the fluid flow path of the drain conduit. The adaptor may be securable in the drain conduit and may be connected to the strainer. Prior to securing the adaptor in the drain conduit, a position of the adaptor in the drain conduit may be moveable to allow a top surface of the strainer to be substantially aligned with the floor. A method of assembly is also disclosed.

First claim

The invention claimed is:

1. A drain assembly for providing drainage to a drain pipe in a floor, the assembly comprising:
a drain conduit having a base, a barrel, an inner surface that defines a fluid flow path, and an outer surface opposite the inner surface;
a strainer disposed above the drain conduit having openings in fluid communication with the fluid flow path of the drain conduit;
an adaptor securable in the drain conduit and connectable to the strainer, wherein prior to securing the adaptor in the drain conduit, the adaptor is movable with respect to the drain conduit so as enable alignment of the strainer with a top surface of the floor; and
a plug sealed to the inner surface of the drain conduit downstream of the barrel relative to the fluid flow path, the plug including a plug member and a seal that cooperate at the inner surface to form a water tight seal between the plug and the inner surface,
wherein the outer surface of the drain conduit is configured to receive a hardenable substratum so as to secure the drain assembly to the drain pipe once the substratum hardens into a hardened substratum, the hardened substratum partially defining the floor, and wherein once the substratum hardens, the adaptor is configured to be movable with respect to the drain conduit so as to level the strainer with a top surface of the floor when the strainer is secured to the adaptor.

2. The drain assembly of claim 1 , wherein the drain conduit further comprises at least an extended flange piece.

3. The drain assembly of claim 2 , wherein the extended flange piece comprises a sleeve portion integrally formed with a flange portion.

4. The drain assembly of claim 3 , wherein the flange portion is secured to the drain conduit with an adhesive.

5. The drain assembly of claim 4 , wherein the drain conduit and the flange portion are made from a polyvinylchloride material and the adhesive is a polyvinylchloride compatible adhesive.

6. The drain assembly of claim 3 , wherein the flange portion is secured to the base with an adhesive.

7. The drain assembly of claim 6 , wherein the base and the flange portion are made from a polyvinylchloride material and the adhesive is a polyvinylchloride compatible adhesive.

8. The drain assembly of claim 2 , wherein the barrel is positionable within the extended flange piece.

9. The drain assembly of claim 2 , wherein the barrel is positionable within the extended flange piece by mating threads of the barrel with threads of the extended flange piece.

10. The drain assembly of claim 1 , wherein the drain conduit further comprises at least a pipe.

11. The drain assembly of claim 1 , further comprising a cap.

12. The drain assembly of claim 11 , wherein the cap is securable to the strainer.

13. The drain assembly of claim 1 , wherein the drain conduit further comprises at least a flange portion and a sleeve portion.

14. The drain assembly of claim 13 , wherein the flange is integrally formed with the sleeve portion.

15. The drain assembly of claim 1 , wherein the position of the adaptor along an axis of the drain conduit inner surface is adjustable and an angle of the adaptor with respect to the axis of the drain conduit is adjustable.

16. The drain assembly of claim 1 , wherein the position of the adaptor along an axis of the drain conduit inner surface is adjustable and an angle of the strainer with respect to the adaptor is adjustable.

17. The drain assembly of claim 1 , wherein the adaptor is slidably disposed in the drain conduit prior to being secured in the drain conduit.

18. The drain assembly of claim 1 wherein the adaptor is tiltable in the drain conduit prior to being secured in the drain conduit.

19. The drain assembly of claim 1 , wherein the adaptor includes an expandable member portion that expands radially outward into contact with the inner surface of the drain conduit to secure the adaptor to the drain conduit.

20. The drain assembly of claim 1 , wherein the plug is coupled to the base.

21. The drain assembly of claim 1 , wherein the plug and seal are coupled to an extended cylindrical piece of the drain conduit.

22. The drain assembly of claim 1 , wherein the plug prevents effluent from flowing upstream of the barrel relative to the fluid flow path.

23. The drain assembly of claim 1 , wherein the plug prevents debris from flowing downstream of the barrel relative to the fluid flow path.

24. The drain assembly of claim 1 , wherein the plug member defines a perimetral surface that extends around a perimeter thereof, the perimetral surface being configured to cooperate with the seal so as to form the water-tight seal with the inner surface of the drain conduit.

25. The drain assembly of claim 24 , wherein the perimetral surface includes threads that engage with corresponding threads of the inner surface so as to form the water-tight seal therebetween.

26. A drain assembly for providing a drain in a floor comprising:
a drain conduit having an extended cylindrical piece, a barrel, an inner surface that defines a fluid flow path, and an outer surface for receiving a hardenable substratum;
a strainer disposed above the drain conduit having openings in fluid communication with the fluid flow path of the drain conduit;
an adaptor securable in the drain conduit and connected to the strainer;
wherein prior to securing the adaptor in the drain conduit, a position of the adaptor in the drain conduit is moveable to allow a top surface of the strainer to be substantially aligned with the floor, and wherein subsequent to hardening the hardenable material at the outer surface of the drain conduit, the adaptor is configured to be movable with respect to the drain conduit so as to level the strainer with a top surface of the floor when the strainer is secured to the adaptor; and
a plug sealed to the extended cylindrical piece downstream of the barrel relative to the fluid flow path, the plug including a plug member and a seal that cooperate at the inner surface to form a water tight seal between the plug and the inner surface.

27. The drain assembly of claim 26 , wherein the extended cylindrical piece comprises a sleeve portion integrally formed with a base portion.

28. The drain assembly of claim 27 , wherein the strainer is securable to the sleeve portion.

29. The drain assembly of claim 27 , wherein the drain conduit further comprises at least a pipe.

30. The drain assembly of claim 29 , wherein the pipe is securable to the base portion.

31. The drain assembly of claim 26 , further comprising a cap.

32. The drain assembly of claim 31 , wherein the cap is securable to the strainer.

33. The drain assembly of claim 26 , wherein the barrel is positionable within the extended cylindrical piece.

34. The drain assembly of claim 26 , wherein the barrel is positionable within the extended cylindrical piece by mating threads of the barrel with threads of the extended cylindrical piece.

35. The drain assembly of claim 26 , wherein the position of the adaptor along an axis of the drain conduit inner surface is adjustable and an angle of the adaptor with respect to the axis of the drain conduit is adjustable.

36. The drain assembly of claim 26 , wherein the position of the adaptor along
