Cargo support assembly

A cargo support assembly for pivotally retaining cargo on a tailgate of a truck bed, said assembly comprising:

• a pair of cross members, each of said cross members having a telescopically adjustable length thereby facilitating each of said cross members to extend laterally across a tailgate of a truck bed, each of said cross members having a first end, a second end and a slot extending substantially between said first end and said second end, each of said cross members having a first foot being perpendicularly oriented with said first end, each of said cross members having a second foot being perpendicularly oriented with said second end, each of said cross members comprising a first half slidably engaging a second half thereby facilitating said cross members to have said telescopically adjustable length, said first end being associated with said first half, said second end being associated with said second half, said first foot associated with each of said cross members having a first aperture extending through said first foot, said second foot associated with each of said cross members having a second aperture extending through said second foot, each of said cross members lying on a top surface of the tailgate having each of said first foot and said second foot being abutted against a respective one of a first lateral edge and a second lateral edge of the tailgate thereby facilitating a plurality of fasteners to be extended through a respective one of said first aperture and said second aperture associated with a respective one of said cross members and engaging a respective one of the first lateral edge and the second lateral edge of the tailgate for attaching said cross members to the tailgate;
• a pair of locks, each of said locks being movably integrated into a respective one of said cross members, each of said locks extending through said slot in said first half and said slot in said second half of said respective cross member, each of said locks being tightenable to compress said first half of said respective cross member against said second half of said respective cross member for retaining said respective cross member at a desired length;
• a pair of brackets, each of said brackets being attached to said pair of cross members such that each of said brackets is perpendicularly oriented with said pair of cross members, each of said brackets comprising a lower panel extending between a pair of outward panels, each of said outward panels being perpendicularly oriented with said lower panel, said lower panel of each of said brackets resting on said pair of cross members having said outward panels of each of said brackets extending away form said cross members, each of said outward panels of each of said cross members having a plurality of holes being spaced apart from each other and being distributed along a respective one of said outward panels;
• a plurality of bracket fasteners, each of said bracket fasteners extending through said lower panel of a respective one of said brackets and extending through said slot in a respective one of said first half and said second half of a respective one of said cross members for fastening said brackets to said cross members;
• a pair of mounts, each of said mounts being removably attachable to a respective one of said brackets, each of said mounts having a receiving element, each of said mounts comprising:
• a channel having an upper panel extending between a pair of sidelong panels, each of said sidelong panels being perpendicularly oriented with said upper panel, each of said sidelong panels having a pair of fastener holes extending through a respective one of said sidelong panels, said upper panel resting on said pair of outward panels of a respective one of said brackets having each of said sidelong panels extending downwardly along a respective one of said outward panels of said respective bracket, said channel being positioned such that each of said fastener holes in each of said sidelong panels is aligned with a respective one of said holes in said respective outward panel of said respective bracket;
• and
• a mount tube being having a lower end being coupled to said upper panel of said channel such that said mount tube extends upwardly from said upper panel, said mount tube having an upper end being open such that said upper end of said mount tube associated a respective one of said mounts defines said receiving element of said respective mount, said mount tube having a lateral wall extending between said upper end and said lower end, said mount tube having a plurality of holes each extending through said lateral wall being spaced apart from each other and being distributed between said upper end and said lower end;
• a pair of support tubes, each of said support tubes being insertable into said receiving element in a respective one of said mounts, each of said support tubes having a plurality of holes extending through an outside wall of said support tubes, each of said support tubes being insertable into said upper end of said mount tube of a respective one of said mounts;
• a pair of pin sleeves, each of said pin sleeves being positioned within a respective one of said support tubes, each of said pin sleeves extending through opposing sides of said outside wall of said respective support tube, each of said pin sleeves being positioned proximate a top end of said respective support tube;
• a plurality of mount pins, each of said mount pins being extendable through a respective one of said holes in said mount tube associated with a respective one of said mounts, each of said mount pins extending through a respective one of said holes in said outside wall of a respective one of said support tubes for retaining said support tubes at a selected height in said mount tube associated with said respective mount;
• a pair of box pivots, each of said box pivots being movably attachable to a respective one of said support tubes such that each of said box pivots freely pivots in said respective support tube, each of said box pivots comprising:
• a panel having a front surface, a back surface and a top edge, said panel having a lobe extending upwardly from said top edge, said lobe being centrally positioned on said top edge;
• a pivot pin being coupled to and extending away from said back surface of said panel, said pivot pin associated with each of said box pivots being insertable through a respective one of said pin sleeves in a respective one of said support tubes such that said panel associated with each of said box pivots is directed toward each other;
• and
• a cotter pin being extendable through a cotter hole in said pivot pin when said pivot pin is inserted through said respective pin sleeve thereby inhibiting said pivot pin from being removed from said respective pin sleeve;
• and
• a box having a pair of engaging elements each being integrated into said box, each of said box pivots being attachable to a respective one of said engaging elements in said box such that said box is pivotally retained between said pair of support tubes thereby facilitating said box to be retained in an upright position whether the tailgate on the truck bed is positioned in a closed position or an open position wherein said box is configured to be accessible to a user when the user opens the tailgate, said box having a first lateral wall and a second lateral wall, said box having a pair of wells each being recessed into a respective one of said first lateral wall and said second lateral wall such that each of said wells defines a respective one of said engaging elements, each of said wells having a bounding edge which conforms to a shape of said panel associated with said box pivots thereby facilitating said panel associated with said box pivots to be inserted into a respective one of said wells, said lobe on said top edge of said panel associated with each of said box pivots engaging a top side of said bounding edge of said respective well for removably retaining said panel associated with each of said box pivots in said respective well.
