Abstract

The apparatus includes metal elongate plates shaped to be received through open ends of the aluminum extruded side walls found on munition containers. The extruded side walls provide excellent side support and overall rigidity to the containers. Each of the elongate plates has an end with an upper slot through which a chain Can slide, therein providing lateral support from a trailer's side rail to the load. Each of the elongate plates has a pronged end with a pair of prongs that projects further outward. The apparatus, in combination with conventional tractor trailer truck gear, functions to provide lateral and longitudinal support to a stack of containers.

Dependent claims

A restraint apparatus that facilitates securing a container during transportation, where the container has a chambered aluminum extruded side walls (ESW) with a left tab that partially occludes a left ESW chamber and a right tab that partially occludes a right ESW chamber, on a flatbed tractor trailer fitted with tie-down gear, comprising:

at least one pair of container truckload restraint feature (CTRF) plates, wherein each of the CTFR plates comprises two sections, a longer section and a shorter section, wherein the longer section has an upper self-adjusting guide open channel to elevate the tie-down gear, and a terminal opening that mainly functions as a finger lift for retrieving a fully chambered CTRF plate, wherein the shorter section has a pronged end with an upper projecting prong and a bottom projecting prong, wherein when the long section is situated in one of the chambered ESW's, the projecting prongs are configured as a guide for one of a chain and a cable,
wherein the at least one pair of CTRF plates comprises a first plate and a second plate, wherein the first plate has a left side abutment feature, which is a right wall and functions as a left stop when the longer section of the first plate is inserted into the left ESW chamber, and wherein the second plate has a right side abutment feature, which is a left wall and functions as a right stop when the longer section of the second plate is inserted into the right ESW chamber.

A restraint apparatus that facilitates securing a stack of containers during transportation, where the stack is at least one layer high, where each of said at least one layer contain's three containers lengthwise, and each of the containers has four useable chambers in a plurality of lower aluminum extruded side walls (ESW), wherein the four useable chambers includes a first chamber and a second chamber, wherein each of the plurality of the aluminum extruded side-walls includes the second chamber with a tab that partially occludes the second chamber, for use on a flatbed tractor trailer equipped with tie-down gear that includes a first tensioned element and a second tensioned element comprising:

two pairs of the restraint apparatus per container so that each said container includes a total of four CRTF plates, wherein each restraint apparatus is a pair of CTRF plates, wherein each of the pair of CTRF plates is comprised of a first plate or a second plate, wherein the first plate and the second plate each have two sections including a longer section and a shorter section, wherein the longer section includes an upper self-adjusting guide open channel configured to elevate at least one of the tensioned elements and a terminal opening configured as a finger lift to facilitate removal of the CTRF plate from a chamber, wherein the shorter section of the first plate has a pronged end that has an upper projecting prong, a bottom projecting prong, and a left abutting wall, wherein the shorter section of the second plate has a prong end, a bottom projecting prong and a right abutting wall,
wherein each container is preloaded with the four CTRF plates, wherein when in a default storage position the finger lifts are nearly flush with opening of the four chambers,
wherein the first tensioned element is affixed to a right rail of the flatbed tractor trailer,
wherein the second tensioned element is affixed to a left rail of the flatbed tractor trailer, and
wherein an opposing side of the stack is similarly connected,
wherein the three containers include a center container and two side containers,
wherein each of the first tensioned element and the second tensioned element is selected from at least one of chains, cables, and straps, and
wherein the tie down gear includes a tensioning element selected from at least one of ratchets, winches, and turnbuckles.
