Abstract

A trench drain includes a trench, a grating seat and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and an outwardly-extending peripheral flange. The grating seat is configured to receive the grating. The peripheral side walls of the trench have a pair of opposing elongated slots formed therein and the grating has a pair of posts on opposing ends thereof. Each of the pair of posts on the grating are received in a respective one of the pair of opposing elongated slots of the trench to establish an axis of rotation.

First claim

What is claimed is:

1. A trench drain comprising:
a trench including
a base wall,
a first wall extending from the base wall,
a second wall extending from the base wall,
a pair of side walls, each extending between the first wall and the second wall,

wherein the base wall, the first wall, the second wall, and the pair of side walls define a trench volume, and
a drain passageway extending downwardly from the base wall to define a distal end opposite the base wall, wherein the distal end has an inner diameter no greater than 4 inches, and wherein the drain passageway is configured to permit the flow of at least 100 gallons per minute of water therethrough; and

a grate at least partially positionable within the trench volume, the grate including a first plurality of bars, wherein at least one bar of the plurality of bars has a longitudinal axis extending therethrough, wherein the longitudinal axis of the at least one bar is oriented substantially parallel to the first wall, wherein the at least one bar includes a bottom surface positioned a first distance from the base wall, a top surface opposite the bottom surface and spaced a second distance from the base wall greater than the first distance, and at least one side surface extending between the top surface and the bottom surface, and wherein at least a portion of the at least one side surface is oriented oblique to the first wall in a vertical orientation.

2. The trench drain of claim 1 , wherein the first wall is longer than at least one side wall of the pair of side walls.

3. The trench drain of claim 1 , wherein the first wall is the same length as the second wall.

4. The trench drain of claim 1 , wherein the first plurality of bars are coupled to a second plurality of bars to form a grid.

5. The trench drain of claim 4 , wherein each bar of the second plurality of bars has a longitudinal axis extending therethrough, and wherein the longitudinal axis of each bar of the second plurality of bars is oriented substantially perpendicular to the first wall.

6. The trench drain of claim 1 , wherein each bar of the first plurality of bars includes at least one side surface oriented oblique to the first wall in the vertical orientation.

7. The trench drain of claim 1 , wherein the at least one side surface oriented oblique to the front wall in the vertical orientation is configured to direct water into the trench volume.

8. The trench drain of claim 1 , wherein the drain passageway includes a first section connected to the base wall defining a first diameter and a second section distal the base wall defining a second diameter that is less than the first diameter.

9. The trench drain of claim 8 , wherein a ratio of the first diameter to the second diameter is between 1.3 and 1.7.

10. The trench drain of claim 8 , wherein a ratio of the first diameter to the second diameter is between 1.4 and 1.6.

11. The trench drain of claim 8 , wherein a ratio of the first diameter to the second diameter is 1.5.

12. The trench drain of claim 1 , wherein the trench is 1.75 inches in height.

13. A trench drain comprising:
an elongated trench including a base wall, a first wall extending from the base wall, and a second wall extending from the base wall, wherein the base wall, the first wall, and the second wall, at least partially define a trench volume therein;
a drain passageway extending through the base to define a distal end opposite the base, the drain passageway defining an axis therethrough, wherein the inner diameter of the distal end is no greater than 4 inches, and wherein the drain passageway is configured to permit the flow of at least 100 gallons per minute of water therethrough; and
a grate at least partially positionable within the trench volume, the grate including a plurality of bars configured to allow fluid to pass therebetween, wherein at least one of the plurality of bars includes a bottom edge positioned a first distance from the base wall and a top edge positioned a second distance from the base wall greater than the first distance, and wherein the top edge is positioned closer to the first wall than the bottom edge.

14. The trench drain of claim 13 , wherein the drain passageway includes a first section connected to the base wall defining a first diameter and a second section distal the base wall defining a second diameter that is less than the first diameter.

15. The trench drain of claim 14 , wherein a ratio of the first diameter to the second diameter is between 1.3 and 1.7.

16. The trench drain of claim 14 , wherein a ratio of the first diameter to the second diameter is between 1.4 and 1.6.

17. The trench drain of claim 14 , wherein a ratio of the first diameter to the second diameter is 1.5.

18. The trench drain of claim 13 , wherein the trench is 1.75 inches in height.

19. The trench drain of claim 13 , wherein the at least one bar of the plurality of bars defines a longitudinal axis extending therethrough, and wherein the longitudinal axis is parallel to the first wall.

20. An elevator trench drain comprising:
an elongated trench defining a trench volume therein, wherein the trench volume defines a trench length and a trench width, and wherein the trench length is greater than the trench width;
a grate at least partially positioned within the trench volume, wherein the grate defines a plurality of elongated openings through which fluid can enter the trench volume, wherein the elongated openings have an opening length and an opening width, wherein the opening length is greater than the opening width, and wherein the trench length is substantially parallel with the opening length; and
a drain passageway open to the trench volume, wherein the drain passageway extends away from the trench volume to produce a distal end opposite the trench volume, wherein the distal end defines an interior diameter that is no greater than 4 inches, and wherein the drain passageway is configured to permit the flow of at least 100 gallons per minute of water therethrough.

21. The elevator trench drain of claim 20 , wherein the elongated openings are rectilinear in shape.

22. The elevator trench drain of claim 20 , wherein the drain passageway includes a first section connected to the base wall defining a first diameter and a second section distal the base wall defining a second diameter that is less than the first diameter.

23. The elevator trench drain of claim 22 , wherein a ratio of the first diameter to the second diameter is between 1.3 and 1.7.

24. The elevator trench drain of claim 22 , wherein a ratio of the first diameter to the second diameter is between 1.4 and 1.6.

25. The elevator trench drain of claim 22 , wherein a ratio of the first diameter to the second diameter is 1.5.

26. The elevator trench drain of claim 20 , wherein the trench is 1.75 inches in height.
