Abstract

A drain assembly comprises a drain pan, a trim member, and a drain cover. The drain pan has a base and a pan sidewall, and the trim member has a trim sidewall. The pan sidewall, at least a portion of the upper surface of the base, and the trim sidewall define a drain channel therebetween. The drain cover defines a plurality of apertures and is positionable above the drain pan. The trim member is configured to transition between a first position and a second position. In the first position of the trim member, the drain channel has a first width that extends in a transverse direction. In the second position of the trim member, the drain channel has a second width that extends in the transverse direction. The first width is different than the second width.

First claim

What is claimed is:

1. A linear drain assembly comprising:
a drain pan having a pan base and a pan sidewall coupled to a first side of the pan base and oriented at an angle relative to the pan base, the pan base having a drain opening formed therethrough, wherein the drain pan lacks a sidewall along at least part of a second, opposite side of the pan base to allow liquid to flow into the drain pan on the second side of the pan base;
a trim member having a trim base and a trim sidewall coupled to the trim base and oriented at an angle relative to the trim base, wherein the trim member is positioned on the pan base such that the trim sidewall, the pan sidewall and at least a portion of an upper surface of the pan base define a drain channel therebetween; and
a drain cover having a plurality of apertures formed therethrough, wherein the drain cover is positioned at least one of in or above the drain channel to allow liquid to flow through the drain cover into the drain channel.

2. The assembly of claim 1 wherein the drain pan is generally “L” shaped in end view.

3. The assembly of claim 1 wherein the pan sidewall is oriented substantially perpendicular to the pan base.

4. The assembly of claim 1 wherein the pan base is generally flat and planar, and wherein the drain pan lacks a sidewall along an entirety of the second side of the pan base.

5. The assembly of claim 1 wherein the drain cover includes first cover wall portion coupled to a second cover wall portion at an apex, a first sidewall coupled to a periphery of the first cover wall portion and a second sidewall coupled to a periphery of the second cover wall portion, wherein the first sidewall is positioned adjacent to the trim sidewall and has a plurality of notches formed therein to allow liquid to flow therethrough.

6. The assembly of claim 1 wherein the assembly further includes a pair of end caps, each end cap being positioned at an end of the drain pan and supporting the drain cover thereon.

7. The assembly of claim 1 wherein the assembly further includes a pair of end dams, each end dam being positioned at an end of the drain pan, wherein each of the end dams includes a base wall supporting the drain pan thereon, includes a first side wall oriented generally perpendicular to the end dam base wall, and includes a second side wall oriented generally perpendicular to the end dam base wall and the first side wall.

8. The assembly of claim 1 wherein the assembly includes at least one wedge positioned in the drain channel and arranged to direct liquid in the drain channel toward the drain opening.

9. A linear drain assembly comprising:
a drain pan having a pan base and a pan sidewall coupled to the pan base and oriented at an angle relative to the pan base, the pan base having a drain opening formed therethrough;
a trim member having a trim base and a trim sidewall coupled to the trim base and oriented at an angle relative to the trim base, wherein the trim member is configured to be positioned on the pan base such that the trim sidewall, the pan sidewall and at least a portion of an upper surface of the pan base define a drain channel therebetween; and
a drain cover having a plurality of apertures formed therethrough, wherein the drain cover is configured to be positioned in or above the drain channel to allow liquid to flow through the drain cover into the drain channel, and wherein the drain cover has a sealing member along one longitudinal side thereof that is configured to sealingly engage the drain pan.

10. The assembly of claim 9 wherein the sealing member is a gasket.

11. The assembly of claim 10 wherein the gasket is positioned along or adjacent to a lower edge of the drain cover.

12. The assembly of claim 10 wherein the gasket is compressed between the drain cover and the drain pan to cause the trim sidewall and drain cover to be pushed into frictional engagement with each other.

13. The assembly of claim 10 wherein at least part of the gasket is generally “D” shaped in end view.

14. The assembly of claim 10 wherein the gasket includes a generally cylindrical base with a slot receiving a portion of the drain cover therein, and a pair of generally parallel positioning walls extending from the cylindrical base.

15. The assembly of claim 9 wherein the sealing member is a bead of sealant.

16. The assembly of claim 9 wherein the assembly includes at least one wedge positioned in the drain channel and arranged to direct liquid in the drain channel toward the drain opening.

17. The assembly of claim 9 wherein the sealing member sealingly engages the pan sidewall.

18. The assembly of claim 9 wherein the sealing member extends along an entire length of the longitudinal side of the drain cover.

19. The assembly of claim 9 wherein the pan sidewall is a one-piece unitary component with the pan base.
