Abstract

A base rail of a trailer includes an upper portion configured to be coupled to the inner surface of a sidewall of a trailer. The upper portion includes a plurality of spaced-apart ridges configured to extend inwardly away from an inner surface of the upper portion and into a storage area of the trailer. The base rail also includes a lower portion configured to be coupled to the floor assembly of the trailer, and a bumper guard coupled to the inner surface of the upper portion and positioned between spaced-apart ridges.

First claim

What is claimed is:

1. A base rail configured to be coupled to a sidewall and floor assembly of the trailer, comprising:
an upper portion configured to be coupled to the inner surface of a sidewall of a trailer, wherein the upper portion includes a plurality of spaced-apart ridges configured to extend inwardly away from an inner surface of the upper portion and into a storage area of the trailer;
a lower portion configured to be coupled to the floor assembly of the trailer;
a bumper guard coupled to the inner surface of the upper portion and positioned between spaced-apart ridges; and
a plurality of rivets coupling the bumper guard to the base rail, wherein a head of each rivet is configured to be positioned adjacent an outside surface of the sidewall of the trailer and an end of each rivet is substantially flush with an inner surface of the bumper guard,
wherein the bumper guard extends further inwardly into the storage area of the trailer than the spaced-apart ridges, and
wherein the bumper guard is made from a material that is harder than the upper portion of the base rail.

2. The base rail of claim 1 , wherein the bumper guard is approximately 1 inch tall and 5/16 inch wide.

3. The base rail of claim 1 , wherein the bumper guard is made of steel and the upper portion of the base rail is made of aluminum.

4. The base rail of claim 1 , wherein the bumper guard is generally half-oval in cross-sectional shape and includes a planar, outer surface adjacent the inner surface of the upper portion and wherein the inner surface of the bumper guard is curved and configured to extend inwardly into an interior of the storage area of the trailer.

5. The base rail of claim 1 , wherein the bumper guard includes a plurality of apertures formed therethrough, and wherein each aperture is tapered from an inner surface of the bumper guard to an outer surface of the bumper guard.

6. The base rail of claim 1 , wherein the bumper guard is positioned between the two upper-most raised ridges of the upper portion.

7. The base rail of claim 6 , wherein a planar surface of the upper portion between the two upper-most raised ridges defines approximately the same height as the bumper guard.

8. The base rail of claim 6 , wherein the bumper guard is positioned between the two upper-most rivets of the plurality of rivets.

9. The base rail of claim 1 , wherein the bumper guard is spaced-apart from the floor assembly and is positioned within an upper half of the upper portion.

10. A base rail configured to be coupled to a sidewall and floor assembly of a trailer, comprising:
an upper portion configured to be coupled to the inner surface of a sidewall of a trailer, wherein the upper portion includes a plurality of spaced-apart ridges configured to extend inwardly away from an inner surface of the upper portion and into a storage area of the trailer;
a lower portion configured to be coupled to the floor assembly of the trailer; and
a bumper guard coupled to the inner surface of the upper portion and positioned between spaced-apart ridges,
wherein the bumper guard includes a plurality of pre-punched apertures formed therethrough, and wherein each pre-punched aperture is tapered from an inner surface of the bumper guard to an outer surface of the bumper guard.

11. The base rail of claim 10 , wherein a width of the bumper guard is greater than a width of the raised ridges.

12. The base rail of claim 10 , wherein the bumper guard is made of a different material than the upper portion of the base rail.

13. The base rail of claim 12 , wherein the bumper guard is made of a harder material than the upper portion of the base rail.

14. The base rail of claim 10 , further comprising a plurality of rivets coupling the bumper guard to the upper portion of the base rail, wherein each of the plurality of rivets includes a head configured to be positioned adjacent an outside surface of the sidewall of the trailer, and an end adjacent and flush with the inner surface of the bumper guard.

15. A method of coupling a base rail to a trailer, comprising:
coupling an upper portion of the base rail to an inner surface of the sidewall;
placing a bumper guard adjacent an inner surface of the upper portion between two raised ridges of the upper portion of the base rail, wherein the bumper guard includes pre-punched apertures;
drilling holes through the upper portion of the base rail and the sidewall using the pre-punched apertures of the bumper guard as a guide; and
inserting rivets through the drilled holes and pre-punched apertures from outside the sidewall to position the head of the rivet adjacent an outside surface of the sidewall.

16. The method of claim 15 , wherein inserting rivets includes bucking an end of the rivet to create a smooth, inner surface of the base rail.

17. The method of claim 15 , wherein coupling an upper portion of the base rail includes inserting rivets through the base rail and the sidewall in order to position the head of the rivets adjacent an inside surface of the upper portion of the base rail.

18. The method of claim 15 , further comprising removing the bumper guard from the upper portion of the base rail, and coupling a second bumper guard to the upper portion of the base rail.
