Abstract

A disclosed corrugated end cap includes a corrugated frame having one or more corrugations defined by one or more sets of alternating peaks and valleys. The end cap also includes one or more ribs disposed in one or more of the valleys and one or more valley reinforcements disposed in the valleys and running over a top surface of the corrugated frame. For example, the one or more ribs may be configured to increase a resistance of the frame to bending. Additionally or alternatively, the top surface, a front surface, and a rear of the corrugated frame surround a recess configured to receive latch ridges from a stormwater chamber.

First claim

What is claimed is:

1. A stormwater system comprising:
a stormwater chamber, the chamber comprising a chamber body and one or more latch valleys disposed at an end of the chamber body; and
an end cap configured to attach to the end of the chamber body to form a lateral wall of the stormwater chamber defined by the chamber body and the end cap, the end cap comprising:
a base;
a frame further comprising one or more openings;
one or more corrugations defined by one or more sets of alternating peaks and valleys emanating from the base and up to a lateral surface of the frame, wherein the peaks and valleys have a curvature between the base and the frame, thereby forming a contoured outer surface of the end cap; and
one or more teeth configured to engage with the one or more of the latch valleys,
wherein the one or more teeth extend outward from the frame and downward from a top of the frame, each tooth corresponding with an opening.

2. The stormwater system of claim 1 , wherein the end cap is latched to the chamber body such that the one or more teeth of the end cap are disposed in the one or more latch valleys.

3. The stormwater system of claim 1 , wherein the at least one tooth contacts the bottom surface of a latch valley.

4. The stormwater system of claim 1 , wherein the stormwater chamber further comprises one or more latch ridges that are disposed at an end of the chamber body.

5. The stormwater system of claim 4 , wherein at least one of the one or more latch valleys adjoins one or more of the latch ridges.

6. The stormwater system of claim 4 , wherein the top of the latch ridge contacts an underside of the frame.

7. The stormwater system of claim 4 , wherein:
the stormwater chamber further comprises one or more peaks, and
the height of the one or more latch ridges is equal to the height of the one or more peaks.

8. The stormwater system of claim 4 , wherein the height of one or more latch ridges varies in size with respect to at least one tooth.

9. The stormwater system of claim 1 , wherein the end cap and chamber body are coupled by welding, fasteners, glue, or tape.

10. The stormwater system of claim 1 , wherein the one or more openings comprise eight openings and the one or more teeth comprise eight teeth.

11. The stormwater system of claim 1 , wherein the end cap further comprises:
one or more ribs disposed in one or more of the valleys configured to increase a resistance of the frame to bending.

12. The stormwater system of claim 1 , wherein the end cap further comprises:
one or more valley reinforcements disposed down a center axis of the one or more valleys and running over a top surface of the frame.

13. The stormwater system of claim 1 , further comprising one or more sub-corrugations disposed in the one or more valleys.

14. The stormwater system of claim 1 , further comprising one or more guide lines disposed across the one or more sets of peaks and valleys such that, from at least one perspective, the one or more guide lines form one or more circular shapes.

15. The stormwater system of claim 11 , wherein the one or more ribs are disposed on an exterior of the end cap.

16. The stormwater system of claim 11 , wherein the one or more ribs are disposed on an interior of the end cap.

17. The stormwater system of claim 12 , wherein the one or more valley reinforcements further run over a rear surface of the frame.

18. The stormwater system of claim 12 , wherein the one or more valley reinforcements are tapered along at least one of a width or a height of the one or more valley reinforcements.
