Abstract
A construction for a cargo trailer side wall providing a plurality of horizontal scruff rails to extend farthest inwardly from the side wall and a plurality of post framing segments which do not extend inwardly past the scruff rails interconnecting one or more of the scruff rails and/or the floor and roof so as to provide a structural frame member reinforcing the side wall.
Claims18
A cargo trailer for use with a motorized vehicle, said trailer comprising:
- a wheel assembly,
- a floor supported by said wheel assembly,
- two side walls extending upward from respective longitudinal sides of said floor,
- a roof,
- a front bulkhead,
- a bottom rail along a bottom of each side wall joining each side wall to the floor, and
- a top rail along a top of each side wall joining each side wall to the roof;
- each side wall comprising:
- a wall panel including an outer surface and an inner surface,
- a plurality of elongate horizontal scruff rails secured to the inner surface of the wall panel spaced vertically from each other, and
- at least one set of a plurality of vertically extending post segments,
- each post segment having an upper end and a lower end,
- a lowermost of the scruff rails spaced upwardly from the bottom rail,
- an uppermost of the scruff rails spaced downwardly from the top rail,
- each scruff rail having an upper side portion, a central rub portion and a lower side portion with the central rub portion between the upper side portion and the lower side portion and extending farthest inwardly from the inner surface of the wall panel, each set of the post segments comprising:
- a lower post segment having its lower end secured to the bottom rail and its upper end secured to the lower side portion of the lowermost scruff rail,
- an upper post segment having its upper end secured to the top rail and its lower end secured to the upper side portion of upper most scruff rail, and
- at least one intermediate post segment having its lower end secured to the upper side portion of a scruff rail immediately therebelow and its upper end secured to the lower side portion of a scruff rail immediately thereabove,
- the post segments in each set disposed in-line with one another to present a continuous vertically extending structural member connecting the bottom rail to the top rail via the post segments of the set and the intervening scruff rails,
- each post segment disposed such that most inwardly directed portions of each post segment do not extend inwardly past the central rub portion.
