Abstract

One embodiment of the application relates to a sink assembly including a sink and a drain cover. The sink includes a basin and a projection provided in a bottom wall of the basin. The projection includes a first portion and a second portion that define a cavity and a drain opening. The first portion extends from the bottom wall at a first orientation and the second portion extends from the first portion at a second orientation that is different than the first orientation. The drain cover is installed into the cavity of the projection. The drain cover includes a base and at least one leg extending downward from a bottom surface of the base. The base has a top surface that is substantially coplanar with an upper surface of the bottom wall, and has an outer periphery that extends beyond an outer periphery of the drain opening.

First claim

What is claimed is:

1. A sink assembly comprising:
a sink including a basin and a projection provided in a bottom wall of the basin, the projection including a first portion and a second portion that define a cavity and a drain opening, the first portion extending from the bottom wall at a first orientation, the second portion extending from the first portion at a second orientation that is different than the first orientation; and
a drain cover installed into the cavity of the projection, the drain cover including a base and at least one leg extending downward from a bottom surface of the base;
wherein a top surface of the base is coplanar with an upper surface of the bottom wall, and an outer periphery of the base extends beyond an outer periphery of the drain opening; and
wherein the first portion tapers inwardly and slopes continuously directly from the bottom wall toward a center of the drain opening to define a frusto-conical shape.

2. The sink assembly of claim 1 , wherein there is a gap between the outer periphery of the base and the first portion.

3. The sink assembly of claim 2 , wherein the outer periphery of the base extends beyond an outer periphery of the second portion.

4. The sink assembly of claim 3 , wherein the second portion of the drain opening is conical shaped.

5. The sink assembly of claim 4 , wherein the drain opening further includes a third portion extending from the second portion at a third orientation that is different than the second orientation; and
wherein the third portion includes an opening that serves as the drain opening.

6. The sink assembly of claim 5 , further comprising a drain removably coupled to the drain opening, wherein the drain includes a flange and a body extending therefrom, the flange being in contact with the third portion.

7. The sink assembly of claim 6 , further comprising a sleeve provided around the at least one leg of the drain cover.

8. The sink assembly of claim 7 , wherein the sleeve has a distal end that is tapered at an angle that is complementary to a profile of the second portion.

9. A sink comprising:
a basin having a bottom wall;
a projection provided in the bottom wall; and
a drain having a flange and a body extending downward therefrom, the drain being removably coupled to the basin;
wherein the projection includes a first portion and a second portion that define a cavity and a drain opening, the first portion extending from the bottom wall at a first angle and having a surface that tapers inwardly and slopes continuously directly from the bottom wall toward a center of the drain opening to define a frusto-conical shape, the second portion extending from the first portion at a second angle that is different than the first angle.

10. The sink of claim 9 , wherein the second portion of the drain opening is conical shaped.

11. The sink of claim 10 , wherein the drain opening further includes a third portion extending downward from the second portion at a third angle that is different than the second angle; and
wherein the third portion includes an opening that serves as the drain opening.

12. The sink of claim 11 , wherein the drain is removably coupled to the third portion such that the flange engages a surface of the third portion and the body extends through the drain opening.
