DETAILED DESCRIPTION

While the features, devices, and apparatus described herein may be embodied in various forms, the drawings show and the specification describe certain exemplary and non-limiting embodiments. Not all of the components shown in the drawings and described in the specification may be required, and certain implementations may include additional, different, or fewer components. Variations in the arrangement and type of the components; the shapes, sizes, and materials of the components; and the manners of connections of the components may be made without departing from the spirit or scope of the claims. Unless otherwise indicated, any directions referred to in the specification reflect the orientations of the components shown in the corresponding drawings and do not limit the scope of the present disclosure. Further, terms that refer to mounting methods, such as coupled, mounted, connected, and the like, are not intended to be limited to direct mounting methods but should be interpreted broadly to include indirect and operably coupled, mounted, connected and like mounting methods. This specification is intended to be taken as a whole and interpreted in accordance with the principles of the present disclosure and as understood by one of ordinary skill in the art.

Referring now to the drawings and particularly to FIG. 1, an example auto-rack car is generally illustrated and indicated by numeral 10. This illustrated example auto-rack car 10 includes a frame 12 supported by trucks 14, each of which have several wheels 16 configured to roll along railroad tracks 18. The frame 12 supports two spaced-apart side walls 20 and a roof 22. The auto-rack car 10 includes a pair of co-acting tri-fold doors 24 and 26 mounted on each end of the auto-rack car 10. Each set of doors 24 and 26 are openable to facilitate the loading and unloading of vehicles into and out of the auto-rack car 10 (and are configured to be closed during transport and storage of the vehicles). It should be appreciated that the present disclosure contemplates that the auto-rack car can be otherwise configured such as with different types of doors or other components.

In this illustrated example embodiment, the side walls 20 each include a series of steel upright posts 28 that are mounted on, and extend upwardly from, the frame 12. The roof 22 is mounted on and supported by these upright posts 28. The upright posts 28 are spaced along the entire length of both side walls 20 of the auto-rack car 10. A plurality of rectangular galvanized steel side wall panels 30 that generally extend horizontally and are vertically spaced apart are mounted between various pairs of upright posts 28. These side wall panels 30 are supported at their corners by brackets (not shown) that are suitably secured to the respective upright posts 28. Each side wall panel 30 has a multiplicity of round side wall panel holes 33. These side wall panel holes 33 provide the auto-rack car 10 with natural light as well as proper ventilation. Proper ventilation prevents harm from the toxic vehicle fumes to the loaders loading or unloading the vehicles into or out of the auto-rack car 10. The auto-rack car 10 in this illustrated example embodiment is a bi-level auto-rack car having a first deck (not shown) and a second deck 50.

Referring now to FIG. 2, certain components of the auto-rack car 10 are shown. Particularly, FIG. 2 shows of a portion of the deck 50 of the auto-rack car 10 attached to a plurality of example upright posts of the auto-rack car 10 and particularly to upright posts 28, 28a, 28b, 28c, 28d, and 28e of the auto-rack railroad car 10 by a plurality of example deck connector assemblies 100, 100a, 100b, 100c, 100d, and 100e of the present disclosure. The deck 50, the upright posts (such as upright posts 28, 28a, 28b, 28c, 28d, and 28e) and the deck connector assemblies 100, 100a, 100b, 100c, 100d, and 100e are configured to facilitate part of the manufacture of the auto-rack car 10, and specifically, connection of the deck 50 to the upright posts 28, 28a, 28b, 28c, 28d, and 28e via the plurality of deck connector assemblies 100, 100a, 100b, 100c, 100d, and 100e as further described herein.

As also further explained below, the present disclosure provides a method of manufacturing an auto-rack car that generally includes, for each respective deck connector assembly and each respective upright post: (1) attaching brackets of the deck connector assembly to the deck; (2) attaching wedges of the deck connector assembly to the upright post; and (3) lowering the deck such that the brackets of the deck connection assembly engage the upright post and the wedges attached to the upright post. The resulting connection between the deck (via the brackets and the wedges) and the upright posts: (1) rigidly attaches the deck to the upright posts; (2) substantially prevents outward lateral movement of the upright posts relative to the deck; and (3) substantially prevents inward lateral movement of the upright posts relative to the deck. The present disclosure also eliminates the use of various bolts to locate and secure the deck to the upright posts,

Additionally, it should be appreciated that when cargo weight (such as vehicles or other goods being shipped) is loaded onto the attached deck, the additional weight tightens the connection between the deck and the upright posts.

The deck connection assemblies present of the present disclosure therefore generally provide: (1) a strong connection between the deck and the upright posts; (2) structural support for the entire auto-rack car; (3) a relatively quick manufacturing process for attaching decks to upright posts; and (4) a quick and simple adjustment of deck height(s) for different size manufactured vehicles between trips by a single person and without the need to send the auto-rack car to a rail car maintenance facility. The deck connection assemblies also reduces out of service time for operators of the auto-rack car.

It should further be appreciated that the present disclosure thus contemplates: (1) new railroad cars; (2) new deck connections assemblies; (3) new methods of manufacturing railroad cars; (4) new methods of reconfiguring decks railroad cars; and (5) elimination of various bolts to locate and secure the deck to the upright posts.

The example illustrated in the Figures includes a deck connector assembly wherein the wedges 400 and 500 are connected to the post 28. However, it should be appreciated that in alternative embodiments of the present disclosure the wedges 400 and 500 are instead connected to the deck 50, and the wedge engagement bracket 110, first post clamping bracket 200, and second post clamping bracket 300 are connected to the upright post 28. In this case, the orientation of the various components may be reversed and/or flip upside down, such that the deck 50 attached to the wedge(s) is held in place by gravity in between the wedge engagement bracket 110, first post clamping bracket 200, and second post clamping bracket 300.

The example shown in the Figures includes the wedges 400 and 500 attached to the interior surfaces of the first flange 72 and the second flange 74 of the post 28. This is illustrated in FIG. 15A, and described above. It should be appreciated that alternative embodiments include attaching the wedges 400 and 500 to the exterior surfaces of the first flange 72 and the second flange 74. This embodiment is illustrated in FIG. 15B, and described above. In certain such alternative embodiments, the wedge engagement bracket 110 may be vertically disposed and engaged with the first flange 72 and the second flange 74. The first post clamping bracket 200 and the second post clamping bracket 300 may then be in contact with the wedges 400 and 500 on the exterior surfaces of the flanges 72 and 74.

Various other embodiments include first and second wedges attached to the interior surfaces of the flanges 72 and 74, as well as third and fourth wedges attached to the exterior surfaces of flanges 72 and 74. This embodiment is illustrated in FIG. 15C, and described above. The wedge engagement bracket 110 may be in contact with the first and second wedges, while the first clamping bracket is in contact with the third wedge on the outside of the flange 72, and the second clamping bracket is in contact with the fourth wedge.

Various components are described according to specific embodiments shown in the Figures. It should be appreciated that these components may have different shapes, orientations, and/or arrangements than those specifically shown. For example, the surfaces of the block 410 are described as being rectangular in shape, and it should be appreciated that other shaped surfaces may be used. In addition, the shapes of the three plates of each post clamping bracket may be different than those shown. Further, in some examples the post clamping brackets may extend from the deck itself, rather than being attached to the wedge engagement bracket as described herein. These examples are not an exhaustive list, and it should be appreciated that other components described herein may have different shapes, sizes, connections, and/or orientations while maintaining the same functionality as those shown in the figures.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention, and it is understood that this application is to be limited only by the scope of the claims.
