Cargo box drop-down gate assembly

The present invention relates to a drop-down gate assembly of a cargo box for a vehicle. The drop-down gate assembly includes a gate operably coupled to the cargo box by an upper connection assembly and a lower connection assembly, each assembly including a kickout link mechanism for laterally positioning the gate with respect to the cargo box and a roller mechanism for vertically positioning the gate with respect to the cargo box. In this manner, the gate is positioned laterally outwardly to provide clearance from the vehicle and vertically downwardly to facilitate access to the interior volume of the cargo box.
