Abstract
A collapsible wagon includes a base and one or more upstanding walls forming a container for cargo. The upstanding walls are 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 pinchless internal mechanical stop that eliminates pinch points where a user's fingers can be pinched during folding and unfolding of the walls. In some embodiments, the wagon includes a gang-operated latch system for releasably securing the endwalls to the sidewalls that is quick, easy, and reliable to use for folding and unfolding. And in some embodiments, the wagon includes a latch system that eliminates slack or play when in the unfolded use position for structural integrity.
