Abstract

A trench drain assembly includes a cross-bar that can swivel into arcuate guides in the sidewalls of the trench drain assembly and a grate clip assembly for reversibly attaching a grate to a cross-bar, whether of the swivel in type described herein or a cross-bar of a different style.

First claim

What is claimed is:

1. A trench drain assembly comprising:
a pair of trench sidewalls;
a cross-bar extending between the pair of trench sidewalls;
a grate spanning between the pair of trench sidewalls and extending along an axial direction of the trench drain assembly;
a grate clip assembly having a grate clip and a fastener, the grate clip having a pair of deformable catch arms connected by a bridging section, the fastener being coupled to the grate clip and securing the grate to the grate clip; and
wherein the pair of deformable catch arms are configured to reversibly engage the cross-bar.

2. The trench drain assembly of claim 1 , wherein the grate is secured between the fastener and an upper surface of the bridging section of the grate clip.

3. The trench drain assembly of claim 1 , wherein the grate clip further includes upper engagement surfaces disposed upwardly from the bridging section of the grate clip and, when the grate is secured to the grate clip, the grate is secured between the fastener and the upper engagement surfaces of the grate clip.

4. The trench drain assembly of claim 1 , wherein each trench sidewall of the pair of trench sidewalls includes an arcuate guide disposed proximate an upper end of the corresponding trench sidewall, the cross-bar includes a pair of tabs extending from opposite ends of the cross-bar, and each tab of the pair of tabs is configured to engage one of the arcuate guides of the pair of trench sidewalls.

5. The trench drain assembly of claim 4 , wherein each tab of the pair of tabs includes an extension extending parallel to an edge of the corresponding end of the cross-bar.

6. The trench drain assembly of claim 1 , wherein the pair of trench sidewalls each include an arcuate guide disposed proximate an upper edge of the corresponding trench sidewall, and the cross-bar includes a pair of tabs extending from opposite ends of the cross-bar.

7. The trench drain assembly of claim 6 , wherein each of the pair of tabs is configured to engage one of the arcuate guides of the pair of trench sidewalls.

8. The trench drain assembly of claim 7 , wherein the arcuate guides of the pair of trench sidewalls extend through an upper surface of the corresponding trench sidewall.

9. The trench drain assembly of claim 8 , wherein the arcuate guides allow for the pair of tabs of the cross-bar to be inserted into corresponding arcuate guides and swiveled into engagement with the corresponding arcuate guides.

10. A trench drain assembly comprising:
a pair of trench sidewalls each including an arcuate guide disposed proximate an upper edge of the corresponding trench sidewall; and
a cross-bar extending between the pair of trench sidewalls and including a pair of tabs extending from opposite ends of the cross-bar;
wherein each of the pair of tabs is configured to engage one of the arcuate guides of the pair of trench sidewalls.

11. The trench drain assembly of claim 10 , wherein the arcuate guides of the pair of trench sidewalls extend through an upper surface of the corresponding trench sidewall.

12. The trench drain assembly of claim 11 , wherein the arcuate guides allow for the pair of tabs of the cross-bar to be inserted into corresponding arcuate guides and swiveled into engagement with the corresponding arcuate guides.

13. The trench drain assembly of claim 10 , wherein the cross-bar includes a pair of cross-bar sidewalls connected by a bridging surface, and wherein the pair of tabs extend from the bridging surface.

14. The trench drain assembly of claim 10 , further comprising:
a grate spanning between the pair of trench sidewalls and extending along an axial direction of the trench drain assembly; and
a grate clip assembly having a grate clip and a fastener, the grate clip having a pair of deformable catch arms connected by a bridging section, the fastener being coupled to the grate clip and securing the grate to the grate clip;
wherein the pair of deformable catch arms are configured to reversibly engage the cross-bar.

15. The trench drain assembly of claim 14 , wherein the grate is compressed between the fastener and an upper surface of the bridging section of the grate clip.

16. The trench drain assembly of claim 14 , wherein the grate clip further includes upper engagement surfaces disposed upwardly from the bridging section of the grate clip and, when the grate is secured to the grate clip, the grate is secured between the fastener and the upper engagement surfaces of the grate clip.
