This application is a continuation of and claims priority to co-pending U.S. patent application Ser. No. 17/379,479, filed on Jul. 19, 2021, which is a divisional of U.S. patent application Ser. No. 16/778,133, filed on Jan. 31, 2020, the entire contents of both of which are incorporated by reference herein.
BACKGROUNDThis disclosure relates to wall construction of cargo containers, such as over-the-road trailers, for example. The disclosure further relates to logistics tracks in such wall construction.
SUMMARYIn one aspect, the invention provides a cargo body wall including an interior side defining an interior plane for facing a cargo receiving volume, and an exterior side opposite the interior side. A primary logistics track is elongated in a first direction and situated in the cargo body wall, and a secondary logistics track is elongated in a second direction intersecting the first direction. The primary logistics track includes first and second inward expansions projecting inward of the interior plane, each of the first and second inward expansions having at least one opening therein providing access to a logistics fitting accommodation area within the cargo body wall. The secondary logistics track is arranged to cross the primary logistics track at a position between the first and second inward expansions.
According to another aspect of the invention, a cargo body wall is configured to provide an upstanding vertical wall of a transport cargo body. An interior side of the cargo body wall is provided by one or more panels for facing a cargo area of the cargo body construction, the interior side defining a wall plane. The interior side includes a network of overlapping vertical and horizontal logistics tracks, including nested logistics tracks set into the interior side of the cargo body wall and surface-mount tracks. Profiles of both the nested logistics tracks and the surface-mount logistics tracks include portions that protrude from the wall plane. The surface-mount logistics tracks lie flush against the nested logistics tracks and flush against the one or more panels.
Referring to
In some constructions, each wall 14 is constructed of multiple panels (e.g., panels 120 each defining a sheet plane aligned with the plane P1 and arranged edge-to-edge in sequential fashion along the longitudinal direction with vertically-extending joints 124 therebetween). The panels 120 can abut each other at such joints 124 or can be arranged with a gap between adjacent panel edges 120 at the joints 124. In other constructions, each wall 14 may be formed as a singular integral panel throughout the extent thereof. The illustrated wall 14 is formed of an end panel having a first construction at each longitudinal end of the wall 14 and a plurality (e.g., eleven) of intermediate panels therebetween, each of the intermediate panels having a second construction. In some embodiments, the first and second constructions can have the same sandwich construction, but different edging for making the necessary joints. Each wall panel 120 can have a width W1 and a height H1, each of which is orthogonal to a panel depth or thickness T1. The panel thickness T1 is the nominal thickness of the panel 120 that is present at most or all locations in the panel 120 that are spaced away from the joints 128 formed at peripheral panel edges (see example on right side of
Also with reference to the illustrated embodiment, first ones of the vertical logistics tracks 112A are located at the joints 128 or “splices” formed between the edges of two adjacent panels 120, while other ones (alternating with the first ones along the trailer length L) are located at the mid-panel recesses 132. At each joint 128, the illustrated panel edges of two adjacent panels 120 are aligned with each other along the plane P1 and sandwiched between one of the vertical logistics tracks 112A (acting as an interior splice plate) and an exterior splice plate 136. As shown in the cross-sections of
The exterior splice plates 136 can be flat or contoured to have a central portion of the cross-section thereof that is extended or bulged to the exterior side. At the locations of the mid-panel recesses 132, the accommodation and attachment of the vertical logistics track 112A can be the same as described for the joints 128, except that one panel 120 has a continuous construction underlying the vertical logistics track 112A and there is no “splice” and thus no exterior splice plate 136. As shown on the left of
Although
With continued reference to the illustrated embodiment, the horizontal logistics track 112B is arranged to cross the vertical logistics track 112A at a position (e.g., along the flat portion 154) between the first and second inward expansions 152. Furthermore, as shown in
Like the inward expansion portions of the vertical logistics track 112A, the illustrated horizontal logistics track 112B includes a hat-shaped profile in transverse cross-section. However, the horizontal logistics tracks 112B can have a consistent cross-section throughout all or a majority thereof, and need not necessarily have a hat-shaped or other non-planar profile. The profile of the illustrated horizontal logistics track 112B includes two edge flanges 170 and a raised central portion 174 therebetween. The raised central portion 174 has at least one opening 176 therein providing access to a logistics fitting accommodation area 180 (
