Abstract

A drain assembly comprises a shroud, a shank, and a frame. The drain assembly may further comprise a shim with an angled top surface. The frame may have an angled bottom surface. A rotational orientation of the angled top surface of the shim relative to the shank and a rotational orientation of the angled bottom surface of the frame relative to the shank may be independently adjustable, thereby allowing for the top surface of the frame to be both angularly and rotationally adjusted relative to a central axis of the drain assembly independent of the positional height of the shank. The drain assembly may further comprise a cover having bendable tabs. The bendable tabs may be disposed around a periphery of the cover and may be configured to contact an angled inner surface of an upper bowl of the shroud, such that the bendable tabs bend around the frame, thereby locking the cover onto the frame.

Claims (34)

1. A drain assembly comprising:

a shroud having a threaded radially inward facing surface;

a shank having a cylindrical radially inward facing surface defining a central axis, and a threaded radially outward facing surface configured to threadably engage the threaded radially inward facing surface of the shroud;

a grate defining a plurality of openings;

a frame positioned axially between the shank and the grate, the frame including a recessed surface configured to receive at least a portion of the grate therein; and

a cover positioned such that a plane oriented normal to the central axis will pass through the grate, the frame, and the cover at the same time.

2. The drain assembly of claim 1 , wherein the grate and frame are rigidly coupled to the shank.

3. The drain assembly of claim 1 , wherein the cover includes a top surface and a bottom surface, and wherein the cover includes at least one structural rib extending from the bottom surface.

4. The drain assembly of claim 1 , wherein the cover includes an annular rib disposed on the underside thereof.

5. The drain assembly of claim 4 , wherein the cover includes a plurality of radially extending ribs on the underside thereof.

6. The drain assembly of claim 1 , further comprising at least one radial rib extending from the underside thereof.

7. The drain assembly of claim 1 , wherein the cover is removable.

8. The drain assembly of claim 1 , wherein the cover is removable.

9. The drain assembly of claim 1 , wherein an axis oriented parallel to the central axis will pass through the grate, the frame, and the cover.

10. The drain assembly of claim 1 , wherein the frame is attached to the shank.

11. A drain assembly comprising:

a shroud having a threaded radially inwardly facing surface;

a shank having a cylindrical radially inward facing surface defining a central axis, and a threaded radially outward facing surface configured to threadably engage the threaded radially inward facing surface of the shroud;

a grate defining a plurality of openings;

a frame including a recessed surface configured to receive at least a portion of the grate therein; and

a cover positioned such that the grate and the frame are positioned axially between the shank and the cover, wherein the cover is configured to selectively cover at least one opening of the plurality of openings of the grate, wherein the cover includes a top surface and a bottom surface, and wherein the cover includes at least one protrusion extending from the bottom surface.

12. The drain assembly of claim 11 , wherein the cover is removable.

13. The drain assembly of claim 11 , wherein the cover includes at least one reinforcing rib extending from the bottom surface.

14. The drain assembly of claim 11 , further including a recess formed into the top surface.

15. A drain assembly comprising:

a shroud having a threaded radially inwardly facing surface;

a shank having a cylindrical radially inwardly facing surface defining a central axis, and a threaded radially outward facing surface configured to threadably engage the threaded radially inward facing surface of the shroud;

a cover including a top surface and a bottom surface, wherein the cover includes at least a portion of an annular rib and a radially extending rib extending from the bottom surface;

a grate defining a plurality of openings positioned axially between the cover and the shank; and

a frame positioned axially between the shank and the grate and including a recessed surface configured to receive at least a portion of the grate therein, and

wherein the cover, grate, and frame are all attached to the shank.

16. The drain assembly of claim 15 , wherein the cover covers at least one opening of the grate.

17. The drain assembly of claim 15 , wherein the cover is configured to prevent material from coming into contact with the frame and the grate.

18. The drain assembly of claim 15 , wherein the cover, grate, and frame are rotationally fixed relative to one another.
