Dump truck bed with a chain adherent release device

A dump truck having a chain adherent release device comprising:

• the dump truck having a bed;
• wherein the bed has a lifted position and a flat unlifted position;
• wherein the bed has a bottom and two side walls, an inside configured to hold materials, a front wall, and a back edge;
• wherein the two side walls each have at least one side wall chain attachment point;
• wherein the front wall has at least one front wall chain attachment point;
• wherein inside the bed is the chain adherent release device;
• wherein the chain adherent release device has two bed side chains positioned proximate and parallel the two side walls, at least one bed inner chain spaced between the bed side chains, and at least one bed cross chain approximately perpendicular to the bed side chains and attached to the bed side chains and positioned between the front wall and the back edge of the bed;
• wherein the at least one bed cross chain further comprises a bed front cross chain proximate the front wall and a bed back cross chain proximate the back edge of the bed;
• wherein the bed side chains, the at least one bed inner chain and the at least one bed cross chain form a chain grid;
• wherein the chain grid is not attached to the bottom of the bed;
• wherein at least one side wall chain is attached to one of the bed side chains at a first end and the side wall attachment point at a second end;
• wherein at least one front wall chain is attached to the bed front cross chain at a first end and to the front wall attachment point;
• wherein the bed side chains and the at least one bed inner chain each have a first and a second end;
• wherein for each of the bed side chains and the at least one bed inner chain, the first end is attached to the front cross chain and the second end is attached to the back cross chain;
• wherein the bed front cross chain and the bed back cross chain are not attached to the bed;
• wherein the chain grid moves as the bed is moved to the lifted position and moved to the unlifted position;
• wherein plural ones of the at least one front wall chain attachment point are spaced across the front wall of the bed;
• wherein the bed has a tailgate at the back of the bed;
• wherein the tailgate is attached to the side walls and is hinged;
• wherein on the tailgate is at least one tailgate attachment point;
• wherein the at least one bed cross chain includes a bed middle cross chain;
• wherein the bed middle cross chain is approximately the same distance from the front wall to the back edge of the bed;
• wherein at least one tailgate chain has two ends;
• wherein a first one of the tailgate chain ends is attached to the bed middle cross chain and a second one of the tailgate chain ends is attached to the at least one tailgate attachment point;
• and
• wherein the at least one inner chain, the side chains and the at least one cross chain have a sufficient length to have direct contact with the bottom of the bed and to lie in the bottom of the bed when the bed is in in the flat unlifted position, thereby forming the chain adherent release device.
