(h) BRIEF SUMMARY OF THE INVENTION
An embodiment of the disclosure meets the needs presented above by generally comprising a cargo container, which is substantially cuboid shaped and comprises a pair of sidewalls, a front, a back, a bottom, and a roof. Each sidewall comprises a plurality of louvers. An actuator is engaged to the cargo container and is operationally engaged to each of the plurality of louvers. The actuator is positioned to selectively motivate each of the louvers between a first position a second position. In the first position, the louver is substantially perpendicular to the bottom and each of the plurality of louvers is in a closed configuration. In the second position, the louver is transverse or parallel to the bottom, extends into the cargo container, and each of the pluralities of louvers is in an open configuration. In the open configuration, the pluralities of louvers are configured to allow passage of a crosswind through the cargo container.

(j) DETAILED DESCRIPTION OF THE INVENTION
With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new cargo container assembly embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 5, the louvered sidewall cargo container assembly 10 generally comprises a cargo container 12, which is substantially cuboid shaped and comprises a pair of sidewalls 14, a front 16, a back 18, a bottom 20, and a roof 22. Each sidewall 14 comprises a plurality of louvers 24. The present invention also anticipates one or both of the roof 22 and the back 18 of the cargo container 12 comprising a plurality of louvers 24. The cargo container 12 comprises a semi-trailer 26, as shown in FIG. 1, an intermodal container, a box car, a panel truck, or the like.
The louvers 24 may be substantially perpendicular to the front 16 and the back 18 of the cargo container 12, as shown in FIG. 2, although the present invention anticipates the louvers 24 being substantially perpendicular to the bottom 20 and the roof 22 of the cargo container 12. Each louver 24 may extend substantially between the front 16 and the back 18 of the cargo container 12, although the present invention anticipates compartmentalized cargo containers 12 with each compartment having opposingly positioned pluralities of louvers 24. Each plurality of louvers 24 extends substantially between the bottom 20 and the roof 22. Each plurality of louvers 24 may comprise from three to seven louvers 24, such as the five louvers 24 shown in FIG. 1.
A plurality of cross supports 28 extends between the front 16 and the back 18 of the cargo container 12. The present invention also anticipates a plurality of uprights (not shown) in addition to, or in place of, the plurality of cross supports 28. Each of a plurality of hinges 30 is engaged to and extends between a respective louver 24 and an associated cross support 28 so that each louver 24 is hingedly engaged to a respective cross support 28.
An actuator 32 is engaged to the cargo container 12 and is operationally engaged to each of the plurality of louvers 24. The actuator 32 is positioned to selectively motivate each of the louvers 24 between a first position a second position. In the first position, the louver 24 is substantially perpendicular to the bottom 20 and each of the plurality of louvers 24 is in a closed configuration, as shown in FIG. 1. In the second position, the louver 24 is transverse or parallel to the bottom 20, extends into the cargo container 12, and each of the pluralities of louvers 24 is in an open configuration, as shown in FIGS. 2 and 5. In the open configuration, the pluralities of louvers 24 are configured to allow passage of a crosswind through the cargo container 12.
The actuator 32 may comprise a pair of linkage bars 34, a plurality of pivot bars 36, and a pair of motors 38. Each linkage bar 34 is operationally engaged to a respective plurality of louvers 24. Each pivot bar 36 is engaged to and extends between a respective linkage bar 34 and a respective louver 24 so that each louver 24 is engaged to a respective linkage bar 34 by an associated pivot bar 36. Each motor 38 has a shaft 40 that is operationally engaged to a respective pivot bar 36 so that each linkage bar 34 is operationally engaged to a respective motor 38 through an associated pivot bar 36. The respective motor 38 is positioned to selectively rotate the associated pivot bar 36 to motivate the linkage bar 34 between the bottom 20 and the roof 22 so that an associated plurality of louvers 24 is motivated between the closed configuration and the open configuration. The present invention anticipates the actuator 32 comprising other actuating means, such as, but not limited to, linear actuating devices, hand cranks, and the like.
Each of a plurality of cables 42 is engaged to and extends between each of the louvers 24 of a respective plurality of louvers 24. The cable 42 is configured to stabilize the respective plurality of louvers 24 in the open configuration.
A controller 44 is operationally engaged to the actuator 32 and is positioned to selectively actuate the actuator 32 to motivate the pluralities of louvers 24 between the closed configuration and the open configuration. The controller 44 may comprise a variety of controlling means, such as, but not limited to, switches, dials, touch panels, and the like. The present invention also anticipates the controller 44 comprising a receiver (not shown), allowing a user to control the actuator 32 remotely, such as when driving a semi-truck 46 engaged to a semi-trailer 26.
The present invention anticipates the controller 44 being configured for independent control of the motors 38 of the pair of motors 38. Thus configured, a windward plurality of louvers 24 could be actuated so as to extend upwardly into the cargo container 12, while a leeward plurality of louvers 24 could be actuated so as to extend downwardly into the cargo container 12, thus creating a downward force on the cargo container 12 and providing enhanced stability in high crosswind environments.
In use, the pluralities of louvers 24 are maintained in the closed configuration during transport of the cargo container 12 while it is loaded. The pluralities of louvers 24 can be positioned in the open configuration while transporting the cargo container 12 when it is empty.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
