Abstract

A drain assembly including a shroud, a shank having a cylindrical radially inward facing surface defining an axis, a grate defining a plurality of openings, a frame positioned axially between the shank and the grate, and where the frame is configured to support the grate. The drain assembly also includes a cover removably coupleable to the drain assembly and configured to prevent material from coming into contact with the grate, where the cover includes an axial height defining an axial envelope, and where the grate is positioned within the axial envelope.

First claim

What is claimed is:

1. A drain assembly comprising:
a shroud;
a shank having a cylindrical radially inwardly facing surface defining an axis;
a cover having a cover plate, where the cover plate includes a top surface and a bottom surface, wherein the cover includes at least one annular rib extending from the bottom surface and at least one radially extending rib extending from the bottom surface;
a grate defining a plurality of openings positioned axially between the cover plate and the shank, wherein the grate includes an upper surface and a bottom surface opposite the upper surface; 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 at least one annular rib and the at least one radially extending rib is configured to contact the upper surface of the grate.

2. The drain assembly of claim 1 , wherein the cover is formed from a polymeric material.

3. The drain assembly of claim 1 , wherein the cover obstructs at least one opening of the grate.

4. The drain assembly of claim 1 , wherein the cover is configured to prevent material from coming into contact with the frame and the grate during installation.

5. The drain assembly of claim 1 , wherein the cover and the grate are positioned so that a plane oriented normal to the axis simultaneously passes through both the cover and the grate.

6. The drain assembly of claim 1 , wherein the cover, the grate, and the frame are positioned so that a plane oriented normal to the axis simultaneously passes through the cover, the grate, and the frame.

7. The drain assembly of claim 1 , wherein the cover includes an axial cover height defining a cover height envelope, and wherein the grate is completely positioned within the cover height envelope.

8. The drain assembly of claim 7 , wherein the frame is completely positioned within the cover height envelope.
