Abstract

An adjustable lavatory drain assembly includes a receptor and a cover. The receptor includes a lower end and an upper end. The upper end of the receptor includes an outer flange. The cover is removably coupled to the upper end of the receptor. The cover includes a body having an opening defining a first flow path and a sleeve extending from a bottom surface of the body. The sleeve is adjustably coupled to the upper end of the receptor forming a circumferential gap between an upper surface of the outer flange and a bottom surface of the body. The cover is selectively adjustable relative to the receptor to increase or decrease the circumferential gap. The circumferential gap defines part of a second flow path.

First claim

What is claimed is:

1. An adjustable lavatory drain assembly, comprising:
a receptor having a lower end and an upper end, the upper end of the receptor including an outer flange; and
a cover removably coupled to the upper end of the receptor, wherein the cover comprises:
a body including an opening defining a first flow path; and
a sleeve extending from a bottom surface of the body;

wherein the sleeve is adjustably coupled to the upper end of the receptor forming a circumferential gap between an upper surface of the outer flange and a bottom surface of the body;
wherein the cover is selectively adjustable relative to the receptor to increase or decrease the circumferential gap;
wherein the circumferential gap defines part of a second flow path; and
wherein the receptor includes an inner flange radially extending within the receptor and disposed between the lower end and the upper end, wherein the inner flange is configured to act as a stop for limiting a position of the receptor relative to a drain pipe and a position of the cover relative to the receptor.

2. The assembly of claim 1 , wherein the cover includes a plurality of transition elements connecting the body and the sleeve; wherein the plurality of transition elements are arranged to define a plurality of circumferential openings between the body and the sleeve; wherein the plurality of circumferential openings and the circumferential gap collectively define the second flow path.

3. The assembly of claim 1 , wherein the inner flange includes an upper engagement surface and a lower engagement surface.

4. The assembly of claim 3 , wherein the sleeve is configured to contact the upper engagement surface of the inner flange when the cover is installed in the receptor; and wherein the lower engagement surface is configured to contact a portion of a drain pipe when the receptor is coupled to the drain pipe.

5. The assembly of claim 1 , wherein the sleeve is threadably coupled to the upper end of the receptor.

6. The assembly of claim 1 , wherein the sleeve is press-fit in the upper end of the receptor.

7. The assembly of claim 1 , further comprising a spacer disposed between the sleeve and the lower end of the receptor to set a position of the cover relative to the receptor.

8. The assembly of claim 1 , wherein the body includes an upper surface having a convex shape.

9. The assembly of claim 1 , wherein the body includes a plurality of openings defining the first flow path.

10. An adjustable drain system, comprising:
a lavatory; and
a drain assembly configured to couple the lavatory to a drain pipe, the drain assembly comprising:
a receptor having a lower end and an upper end, the upper end of the receptor including an outer flange; and

a cover removably coupled to the upper end of the receptor, wherein the cover comprises:
a body including an opening defining a first flow path; and
a sleeve extending from a bottom surface of the body;

wherein the lower end of the receptor is configured to be removably coupled to the drain pipe and a bottom surface of the flange is configured to engage the lavatory;
wherein the sleeve of the cover is adjustably coupled to the upper end of the receptor forming a circumferential gap between an upper surface of the outer flange and a bottom surface of the body;
wherein the cover is selectively adjustable relative to the receptor to increase or decrease the circumferential gap;
wherein the circumferential gap defines part of a second flow path; and
wherein the receptor includes an inner flange radially extending within the receptor and disposed between the lower end and the upper end, wherein the inner flange is configured to act as stop for limiting a position of the receptor relative to a drain pipe and a position of the cover relative to the receptor.

11. The system of claim 10 , wherein the first and second flow paths are each configured to: direct a flow of water from the lavatory to the drain pipe, and direct a flow of air from the drain pipe to ambient.

12. The system of claim 10 , wherein the body of the cover conceals the outer flange of the receptor from view.

13. The system of claim 10 , wherein the lavatory is a ventless type lavatory.

14. The system of claim 10 , wherein the cover includes a plurality of transition elements disposed between the body and the sleeve; wherein the plurality of transition elements are arranged to define a plurality of circumferential openings between the body and the sleeve; wherein the plurality of circumferential openings and the circumferential gap collectively define the second flow path.

15. The system of claim 10 , wherein the receptor includes an inner flange disposed between the lower end and the upper end; wherein the inner flange includes an upper engagement surface and a lower engagement surface.

16. The system of claim 15 , wherein the sleeve is configured to contact the upper engagement surface of the inner flange when the cover is installed in the receptor; and wherein the lower engagement surface is configured to contact a portion of the drain pipe when the receptor is coupled to the drain pipe.

17. An adjustable drain assembly for a lavatory, comprising:
a receptor configured to removably couple the lavatory to a drain pipe, the receptor including an upper and a lower end; and
a cover adjustably coupled to the receptor, the cover including an opening defining a first flow path;
wherein a portion of the cover and a portion of the receptor cooperatively define a circumferential gap therebetween, wherein the circumferential gap defines a second flow path;
wherein the cover is configured to move relative to the receptor to selectively increase or decrease a size of the second flow path;
wherein the receptor includes am inner flange radially extending within the receptor and disposed between the lower end and the upper end, wherein the inner flange is configured to act as a stop for limiting a position of the receptor relative to the drain pipe and a position of the cover relative to the receptor.

18. The assembly of claim 17 , wherein the first and second flow paths are each configured to: direct a flow of water from the lavatory to the drain pipe, and direct a flow of air from the drain pipe to ambient.

19. The assembly of claim 17 , wherein the cover includes a plurality of circumferential openings which define part of the second flow path.

20. The assembly of claim 17 , wherein the cover is threadably coupled to the receptor; and wherein the cover is configured to rotate relative to the receptor to selectively increase or decrease the size of the second flow path.
