Sideboard bracket

DETAILED DESCRIPTION In a first manifestation, the invention is a plurality of sideboard brackets for mounting supporting planks of varying or diverse thickness onto a transport vehicle having a dump box.
The brackets rigidly support the planks in an orthogonal orientation while also supporting a load.
They also allow dumping of material from the transport vehicle, between ones of the sideboard brackets.
A front bracket has a corner point where three orthogonal planar surfaces converge, including a first vertical wall and a second vertical wall.
The vertical walls include attachment points, to which supporting planks may be rigidly mounted.
A third orthogonal surface comprises a horizontal base forming an "L" shape having first and second legs and further comprises attachment points for attachment to the transport vehicle.
A tailgate bracket also has a corner point where three orthogonal planar surfaces converge, including a first vertical wall and a second vertical wall and further comprising attachment points to which supporting planks may be rigidly mounted.
A third orthogonal planar surface comprises a horizontal base which extends farther parallel to the vehicle longitudinal axis than transverse, and comprises attachment points for attachment to the transport vehicle.
In a second manifestation, the invention is a means for removably attaching diverse load extending supports to a cargo box, to permit carrying diverse cargo while optimizing the loading, unloading and transport of each diverse cargo type.
A first vertical surface has an attachment point for attachment to a plank.
A second vertical surface perpendicular to the first vertical surface has an attachment point for attachment to a plank.
A base has an attachment point for attachment to a cargo box.
In a third manifestation, the invention is a method for elevating the side walls and top rail of a dump truck body, comprising the steps of forming a first bracket from a sheet stock having three orthogonal surfaces including a base and two vertical side walls; rigidly and removably attaching the first bracket to the top rail; rigidly attaching a first plank at a first end to a first one of the two vertical side walls; anchoring the first plank against movement relative to the top rail; rigidly and removably attaching a second plank to a second one of the two vertical sidewalls; and removably anchoring the second plank against movement relative to the sidewalls
