Abstract

A drain assembly includes a drain body connected to a drain pipe such that the drain body is in fluid communication with the drain pipe; and a drain head assembly adjustably connected to the drain body such that the drain head assembly is in fluid communication with the drain body. The drain head assembly includes a shank adjustably connected to the drain body and a strainer assembly connected to the shank. The strainer assembly includes a strainer, an upper frame, and a lower frame connected to each other. The lower frame includes a connection feature that non-threadably and removably connects the strainer assembly to the shank. The drain assembly further includes a cover removably connected to the shank in a position over the shank and to at least partially define a void in a poured concrete slab around the shank.

Claims

1. A drain assembly, comprising:

a drain body configured to be connected to a drain pipe such that the drain body is in fluid communication with the drain pipe; and

a drain head assembly adjustably connected to the drain body such that the drain head assembly is in fluid communication with the drain body, the drain head assembly comprising;

a shank adjustably connected to the drain body; and

a strainer assembly connected to a top of the shank, the strainer assembly including a strainer, an upper frame, and a lower frame connected to each other,

wherein the lower frame includes a connection feature configured to non-threadably and removably connect the strainer assembly to the top of the shank and the shank of the drain head assembly is located in the drain body;

wherein the connection feature of the lower frame includes at least two flexible hooks extending from a bottom of the lower frame and configured to engage the top of the shank; and

wherein the lower frame includes at least two flexible hooks extending from a top of the lower frame and the upper frame includes a bottom flange, the lower frame being connected to the upper frame by an engagement between the flexible hooks extending from the top of the lower frame and the bottom flange of the upper frame.

2. The drain assembly according to claim 1, wherein the shank includes external threads and is threadably connected to the drain body.

3. The drain assembly according to claim 1, wherein the at least two flexible hooks extending from the bottom of the lower frame comprise six flexible hooks equally circumferentially-spaced around the lower frame.

4. The drain assembly according to claim 1, wherein the shank includes a top ring at the top of the shank, the top ring of the shank being configured to be engaged by the flexible hooks extending from the bottom on the lower frame.

5. The drain assembly according to claim 4, wherein the top of the shank includes at least two sets of lugs extending outward from the top ring, each of the at least two sets of lugs being configured to engage a respective one of the at least two flexible hooks extending from the bottom on the lower frame to prevent rotation of the strainer assembly with respect to the shank.

6. The drain assembly according to claim 1, wherein the strainer, upper frame, and lower frame are connected by fasteners engaging the strainer, upper frame, and the lower frame.

7. The drain assembly according to claim 1, further comprising a rough-in adapter adjustably connected to the drain body,

wherein the shank of the drain head assembly is adjustably connected to the rough-in adapter, and

wherein the rough-in adapter is configured to at least partially define a void in a poured concrete slab.

8. The drain assembly according to claim 7, further comprising a removable cover positioned on the rough-in adapter and the removable cover and the rough-in adapter in combination are configured to define the void in the poured concrete slab.

9. The drain assembly according to claim 8, wherein the cover includes internal hooks for removably connecting the cover to the shank.

10. The drain assembly according to claim 1, further comprising:

a cover configured to be positioned on the drain body over the shank to at least partially define a void in a poured concrete slab around the shank, the cover being configured to be removably connected to the shank.

11. A drain assembly, comprising:

a drain body configured to be connected to a drain pipe such that the drain body is in fluid communication with the drain pipe;

a drain head assembly adjustably connected to the drain body such that the drain head assembly is in fluid communication with the drain body, the drain head assembly including a shank adjustably connected to the drain body in which the shank is located;

a cover configured to be removably connected to the shank in a position over the shank and to at least partially define a void in a poured concrete slab around the shank; and

a protector sleeve configured to be positioned between a bottom of the cover and the drain body and surrounding the shank;

wherein the cover includes at least one projection on the bottom of the cover;

wherein the cover and the protector sleeve in combination are configured to define the void in the poured concrete slab, and the at least one projection on the bottom of the cover is configured to engage the shank to removably connect the cover to the shank;

wherein the at least one projection on the bottom of the cover includes an outer annular projection forming an outer ring within a perimeter of the cover, a plurality of inner arc-shaped projections concentric with the outer annular projection, and at least two inner flexible projections circumferentially aligned with the inner arc-shaped projections configured to engage the shank to removably connect the cover with the shank;

wherein the inner arc-shaped projections and the at least two inner flexible projections form an inner ring within a diameter of the outer ring formed by the outer annular projection to define a channel between the inner and outer rings; and

wherein the inner and outer rings are configured to engage and retain the protector sleeve within the channel.

12. The drain assembly according to claim 11, wherein the cover is configured to be positioned on the drain body over the shank and includes internal hooks for removably connecting the cover to the shank.

13. The drain assembly according to claim 11, wherein the at least two inner flexible projections include snap hooks configured to engage a top ring of the shank.

14. The drain assembly according to claim 11, wherein the drain head assembly further includes a strainer assembly removably connected to a top of the shank, the strainer assembly including a strainer, an upper frame, and a lower frame connected to each other, and

wherein the lower frame includes a connection feature configured to non-threadably and removably connect the strainer assembly to the top of the shank.

15. The drain assembly of claim 11, wherein the cover is impenetrable by concrete and lacks openings.
