<p>A folding trailer system for an automobile has the drawbar of the trailer with a joint (42) and with the frame of the trailer folding about a middle line to form a compact pack. The drawbar is swung into a vertical position with the folded trailer body and is locked onto the towing hitch via a locking bolt threaded through the hitch, e.g. through the towing ball, and with a forked slider gripping under the towing ball for added security.</p> |
