  • Patent number: 5857825
    Abstract: An articulated vehicle has features that facilitate loading and unloading. The vehicle includes a truck and a trailer. The truck is loaded from the rear, as in the case of a pickup truck with an endgate or tailgate. The trailer is coupled to the truck by a tongue on the undercarriage of the trailer. The trailer includes a bed and a front section. The bed, when released from the tongue pivots toward the ground so that a load can be rolled from the ground onto the bed. The front section is hinged to the bed. When the front section is unlocked from an upright position, it extends over the tongue to be supported in part by the tailgate. A hinged riser on the tongue supports the bed and the section as the load is rolled from the bed into the truck. When unloading, the bed tips toward the ground as the load is rolled off the bed. The articulated vehicle loads and unloads without a separate ramp, dock, or tailgate lift.
