Open-bed utility trailer convertible to a closed utility trailer by the addition of a closed cargo box

摘要

A utility trailer convertible between an open bed configuration and a cargo box configuration includes an open-bed trailer and a removable cargo box. The bed of the trailer includes multiple full-length, parallel, longitudinal grooves. Adjacent each groove is a rail that is elevated slightly above the elevation of the bed. The rails function both as deck protectors and friction reducers for the cargo box that is designed for a slide-in, non-interference fit between the walls of the trailer. The cargo box-has a sheathing covered frame with a door at the rear end thereof. Multiple anchors that align with the grooves, are attached to the underside of the cargo box frame. When properly positioned on the trailer, the anchors are removably securable to the bed. Multiple jacks can be used to elevate the cargo box and slide the trailer from beneath the cargo box.
