Abstract: A supplemental tailgate extends from the tailgate frame of a pickup truck and is positionable in multiple orientations to provide a variety of uses, including as an extension of the pickup truck bed. The supplemental tailgate includes a cross member connected between two telescoping supports, which forms a part of the tailgate molding when stored within the main tailgate structure. A lock rod assembly interconnects the supplemental tailgate and the body of the pickup truck to stabilize the position of the extended supplemental tailgate when positioned perpendicular to the opened main tailgate. The lock rod assembly can be formed as flexible cables that can be housed within the cross member for easy deployment when needed. The lock rod assembly can also be formed as fixed length rods that are pivotally mounted on the cross member and stored within the cross member for easy deployment.

Abstract: A lock rod support member can be stowed within a support tube housed in the body of the pick-up truck on which a supplemental tailgate assembly to be deployable from the tailgate structure of the pick-up truck. The support tube for the lock rod can be mounted internally of the D-pillar of the pick-up truck body with the lock rod extendible therefrom, or mounted beneath the top rail of the pick-up truck bed from which the lock rod can be extended, for engagement with the deployed supplemental tailgate assembly. A stop bracket positioned at the end of the lock rod support tube engages and positions the formed distal end of the lock rod for appropriate positioning for engagement with the supplemental tailgate assembly. A spring latch mechanism is mounted on the opposing ends of the supplemental tailgate structure for clasping the insertion end of the lock rod members.

Abstract: A pivotable grab handle device is movable between a stowed position, which is positioned within a mating cavity formed in the main tailgate structure, and a deployed position that projects upwardly above the top surface of a lowered main tailgate structure. The grab handle device is mounted on a retainer bracket that is affixed to a pivot bracket mounted to the top surface of the lowered main tailgate structure. When pivotally raised into the deployed position, the grab handle allows a person using a supplemental tailgate assembly configured into a step function extending below the plane of the lowered main tailgate structure to be stabilized while climbing onto the cross member of the supplemental tailgate assembly and onto the top surface of the lowered main tailgate structure.
