    DETAILED DESCRIPTION OF THE INVENTION

    Description of Multilevel Railcar Safety Catch System

    (11) At the outset, it should be clearly understood that like reference numerals are intended to identify the same structural elements, portions, or surfaces consistently throughout the several drawing FIGS., as may be further described or explained by the entire written specification of which this detailed description is an integral part. The drawings are intended to be read together with the specification and are to be construed as a portion of the entire written description of this invention as required by 35 U.S.C. 112.

    (12) The multilevel railcar safety catch system of the present disclosure comprises at least two multilevel railcars (or at least one multilevel railcar plus a vehicle loading ramp), at least two bridge plates, and a safety catch assembly. In the preferred embodiment of the disclosure, two or more multilevel railcars are coupled together by a coupler. Two bridge plates are laid across the gap between corresponding multilevel railcar decks for the purpose of walking or moving vehicles across from one multilevel railcar to another. A safety catch assembly is removably attached underneath the bridge plates via a securement means on the safety catch assembly and barrel rings or bridge plate hinge pins in such a way as to prevent persons or items from falling through the gap between the multilevel railcar decks when loading or unloading vehicles.

    (13) Multilevel railcars are used to ship automobiles from plant sites and auto origin locations to destinations for offloading. Once the multilevel railcar arrives at a destination facility, the multilevel railcars are connected together via a coupler. This coupler is the only stationary permanent device between the two multilevel railcars, and is also a primary hazard in the event someone or something was to fall from a height on top of it.

    (14) A multilevel railcar has two or three decks (or floors), and vehicles are secured to the deck of each multilevel railcar for transportation. During loading and unloading, multilevel railcars are matched together by deck heights and are attached by a coupler. Once coupled together, an individual multilevel railcar worker will open and secure the multilevel railcar doors, then climb up the side of the multilevel railcar on a stationary mounted ladder. Once said individual has reached the desired multilevel railcar deck, the individual will adjoin the adjacent multilevel railcar deck by installing two portable bridge plates.

    (15) The bridge plates are installed by laying one end of a bridge plate across the surface of a multilevel railcar deck, and securing the other end of the bridge plate on the opposing multilevel railcar deck by sliding a solid metal bridge plate hinge pin alternately through barrel rings attached to both the multilevel railcar deck and to the bridge plate itself. In the preferred embodiment of the present disclosure, the individual multilevel railcar worker will secure a safety catch assembly to the multilevel railcar deck by sliding said bridge plate hinge pin through safety catch assembly rings simultaneously with securing said bridge plate hinge pin to said barrel rings. On the opposing multilevel railcar deck, said safety catch assembly will preferably be coupled to the unused barrel rings attached to the opposing multilevel railcar deck by means of a securement device such as a carabiner. A number of additional examples of use and means of connection will be readily apparent to those skilled in the art.

    (16) The safety catch assembly is generally comprised of a safety catch fabric, a plurality of connection grommets, and a plurality of securement devices. Another embodiment of the safety catch assembly will also include a plurality of rigid bars. The safety catch fabric is preferably constructed from a lightweight woven or semi-porous material that will sustain the weight of an individual, will allow for the drainage of water cause by spillage, rain, or the melting of snow or ice, and will flex over a multilevel railcar coupler, if necessary, thereby affording protection at all multilevel railcar deck heights.

    (17) In the preferred embodiment of the disclosure, the safety catch fabric will measure between thirty-eight and forty-six inches in length by eighty inches in width (38-4680), which will allow the safety catch assembly to fit securely on any coupled multilevel railcars meeting the standard guidelines set forth by the Association of American Railroads' (AAR) Manual on Portable Bridge Plates for Multi-Level Autorack Cars. In additional embodiments of the safety catch assembly, the size of the safety catch fabric can be adjusted to fit multi-level railcars of different standards.

    (18) In one embodiment of the disclosure, the safety catch fabric will have a rigid bar along each end of said fabric's width. The purpose of said rigid bars is to allow the safety catch assembly to sit flush against the multilevel railcar deck, with minimal gapping. The safety catch fabric has a plurality of connection grommets running along the width and adjacent to said rigid bars, which serve as areas of attachment for the plurality of securement devices. In the preferred embodiment of the disclosure, said safety catch fabric is configured with four (4) connection grommets along each width, for a total of eight (8) connection grommets, each with a corresponding securement device. In the preferred embodiment, the spacing along each end of the safety catch fabric of the first and second connection grommets shall preferably be between seventeen and eighteen inches (17-18) apart on center, approximately forty-three inches (43) between the second and third connection grommets, and approximately seventeen and eighteen inches (17-18) between the third and fourth connection grommets. The preferred spacing will provide for a taut assembly, as well as allow for proper attachment to standard bridge plate hinge pin and barrel ring assemblies, though the spacing can be altered in additional embodiments to comply with additional barrel ring standards.

    (19) In addition to providing an individual with protection from falling through the gap between the decks of two coupled multilevel railcars, another embodiment of the multilevel railcar safety catch system provides an individual with protection from falling through the gap between two bridge plates of a vehicle loading ramp (e.g. a Buck or Lesco loading ramp). In the instant embodiment, said vehicle loading ramp will need to be retrofitted with a plurality of sleeves or hooks similar to barrel rings, welded along the bottom of each bridge plate, said plurality of sleeves or hooks to serve as attachment points for the safety catch assembly.

    (20) Averting now to the drawings, with reference to FIG. 1, side perspective view is depicting the multilevel railcar safety catch system according to the disclosure. A first multilevel railcar 40 is connected to second multilevel railcar 40 via a coupler 42. A plurality of vehicles 46 are shown resting on multilevel railcar deck 44, and are loaded onto and unloaded off of multilevel railcar 40 via a vehicle loading ramp 50. Vehicles 46 are moved from first multilevel railcar 40 to second multilevel railcar 40 (and to any subsequent multilevel railcars, not shown) via bridge plates 30. When an individual worker (not shown) maneuvers on foot from multilevel railcar 40 to multilevel railcar 40 via said bridge plates 30, safety catch assembly 10 protects said individual worker in the case of an accident from falling onto coupler 42 through a gap between the multilevel railcars 40 and bridge plates 30 (see FIGS. 3, 4). FIG. 1 depicts multilevel railcar 40 capable of holding two vehicles 46 per multilevel railcar deck 44, however the preferred embodiment of the disclosure is compatible with any size multilevel railcar allowed under standard AAR guidelines.

    (21) Referring now to FIG. 2, there is depicted a multiple-perspective view of safety catch assembly 10 according to the disclosure. Safety catch assembly 10 is comprised of a safety catch fabric 20, a plurality of connection grommets 14, and a plurality of securement devices 12, 16. In the preferred embodiment of the disclosure, safety catch assembly 10 will utilize a plurality of rings 12 as a securement means. However, other embodiments may use a combination of rings 12 and carabiners 16, or any other means of securement known in the art. One embodiment of safety catch assembly 10 has at least one rigid bar 18 running adjacent to connection grommets 14, for the purpose of eliminating gaps between safety catch assembly 10 and multilevel railcar deck 44 (as hereinafter described in FIGS. 3, 4).

    (22) With reference now to FIG. 3, there is depicted a perspective view from inside a multilevel railcar 40 showing the multilevel railcar safety catch system according to the disclosure. Multilevel railcar 40 is shown with car 46 resting on multilevel railcar deck 44. Extending out from multilevel railcar 40 are two bridge plates 30, said bridge plates 30 coupled to multilevel railcar 40 via a plurality of barrel rings 32 and a bridge plate hinge pin 34. In the preferred embodiment, safety catch fabric 20 is coupled to bridge plates 30 and multilevel railcar deck 44 via rings 12.

    (23) With reference now to FIG. 4, there is depicted a bottom perspective view showing the multilevel railcar safety catch system according to the disclosure. Another embodiment of safety catch assembly 10 is shown with safety catch fabric 20 coupled to multilevel railcar deck 44 and to bridge plates 30 via multiple means of securement. In the preferred embodiment, each means of securement has a ring 12 passing through a connection grommet 14, and then through another ring 12. On one side of safety catch assembly 10 as depicted in FIG. 4, an additional ring 12 is coupled to bridge plate hinge pin 34, while on the opposing side of safety catch assembly 10, a carabiner 16 is coupled to a barrel ring 32. FIG. 4 illustrates safety catch assembly 10 with rigid bars 18, which serve to tighten any gap between safety catch fabric 20, bridge plates 30 and multilevel railcar deck 44.
