DETAILED DESCRIPTION OF THE INVENTION

[0014] The system of the present invention is provided to secure and immobilize stacked intermodal chassis 100,102, 104, and 106, each intermodal chassis having intermodals 101, 103, 105 and 107, interconnected by lateral, horizontally extending frames 108, 109, 110, and 111. The system of the present invention comprises a plurality of elongated, vertical supports 2 and 4. It is contemplated that additional vertical supports can also be utilized. Each vertical support has a series of vertically aligned through holes 6 and 8. Connector members 10, 26, and 38 are provided to conjoin vertical supports 2 and 4 to intermodal chassis 100, 102, 104, and 106. These different connector members are available to be used, depending on the configuration of the intermodal chassis and the manner in which they are to be stacked.

[0015] Connector member 10, as seen in FIG. 5, comprises three sections: first section 12 which is horizontal and substantially flat, second curved, U-shaped section 14, and third section 16 having through openings 18 and 20. Third section 16 is substantially perpendicular to first section 12 and is configured to attach connector member 10 to vertical support 2 by means of threaded bolt members 22 and 24 and washer nuts 23 and 25.

[0016] Connector member 26, as best seen in FIG. 6, comprises first horizontal, substantially flat section 28, second curved, U-shaped section 30, and cylindrical shaped third section 32 extending from first section 28. Third section 32 has threaded end 34 and is configured to attach connector member 26 to vertical support 2, using washer nut with cotter pin lock 27.

[0017] Connector member 38, as best seen in FIG. 7, comprises horizontal first section 40, second section having curved loop shaped eye 42 at its distal end, and third section 44 having threads 46 which are configured to attach connector member 38 to vertical support 2, using washer nut with cotter pin lock 39.

[0018] In use, vertical supports 2 and 4 (and additional vertical supports if desired) are placed, upright in spaced relation to each other, next to stacked intermodal chassis 100, 102, 104, and 106, on both sides of the stacked chassis. For example, first section 12 of connector member 10 is overlaid onto frame 110 of the intermodal chassis, e.g. chassis 104 as seen in FIG. 4, with its curved section 14, extending over the frame. Connector member 10 is then positioned with its third section 16 adjacent to vertical support 2, such that through openings 18 and 20 of the third section are aligned with holes 6 of the vertical support. Bolt members 22 and 24 are inserted into through openings 18 and hole 6 and through opening 20 and hole 6, respectively. Washer nuts 23 and 25 are then screwed onto bolts 22 and 24 to rigidly secure vertical support 2 to intermodal chassis 104. This process is continued for every location in which vertical support 2 is positioned adjacent to the frames of intermodal chassis 100, 102, 104, and 106 and to each vertical support placed next to the stack of intermodal chassis.

[0019] While four stacked intermodal chassis are depicted, the system of the present invention can accommodate as little as two and as many as five stacked chassis.

[0020] Alternate connector members are available to be used in combination with the vertical supports. For instance, as seen in FIGS. 2 and 3, first section 28 of connector member 26 is positioned under frame 109 of intermodal chassis 102, with its curved second section 30 extending over the frame. Connector member 26 is then positioned such that threaded end 34 of third section 32 extends through hole 8 of vertical support 4. Washer nut 27 is screwed onto threaded end 34 of the third section to rigidly secure vertical support 4 to intermodal chassis 102. This process is continued with the other vertical supports, as has been previously described with regard to connector member 10.

[0021] It is noted that while each of the stacked intermodal chassis must be secured via vertical supports by at least one connector member, multiple connectors can be utilized for each chassis. Connector members 10 and 26 can be used interchangeably based on the positions of the chassis' frames and the vertical supports.

[0022] Connector members 38 can also be used in combination with strap 50 to provide an additional attachment to secure the stacked intermodal chassis. As best seen in FIGS. 2 and 3, first section 40 and curved loop shaped eye second section of lower connector member 38 is positioned through the bottommost opening 8a in vertical support 4. Third section 44 is then inserted through opening 8a as well, wherein washer nut 39 is screwed onto the threaded end of the third section. Strap 50 is attached to second section 42 via its loop shaped eye by strap hook 52 and then extended up to the top opening of the opposite vertical support on the other side of the stacked intermodal chassis. There the strap is connected to second strap hook 52 which is then linked to a second connector 38 attached to the opposite vertical support.

[0023] Thus, proper utilization of the vertical supports and the various connector members of the present invention will effectively serve to secure, stabilize, and immobilize stacked intermodal chassis.

[0024] Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
