Abstract
A wagon includes a base and at least two upstanding walls forming a container for cargo. At least one of the upstanding walls is pivotally mounted to the base for pivoting between an unfolded position for use and a folded position for storage and transport. In some embodiments, the wagon includes a minimized-play feature that eliminates slack or play when in the unfolded use position for structural integrity. And in some embodiments, the wagon includes a gang-operated latch system for releasably securing the walls in the unfolded use position that is quick, easy, and reliable to use for folding and unfolding.
