Abstract
A retractable bed is capable of handling heavy cargoes to an extended length approximately double the retracted length. The retractable bed comprises a fixed frame, a secondary frame, and a top frame. A unique arrangement of rollers engages the various frames. The top frame, which supports the cargo deck, is supported by both the fixed and secondary frames. The invention includes a locking device that is spring loaded to automatically lock the frames in selected locations between the extended and retracted positions. The locking device has a handle that extends to the front of the top frame, where it is conveniently operated by a person.
