Collapsible wagon

摘要

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.

主权项

1. A collapsible wagon for cargo, comprising:
a base; at least one wall that is pivotally mounted to the base and that pivots relative to the base between a folded position for storage and an unfolded position for use, wherein in the unfolded position the wall extends generally upward from the base to cooperatively form a container for holding the cargo; and at least one pivotal coupling that pivotally mounts the wall to the base, wherein the pivotal coupling includes an anchor fixedly mounted to the base and a pivot fixedly mounted to the wall so that the pivot moves with the pivotal wall, wherein the anchor includes a fixed housing and either two stop surfaces or a stop member internally contained within the anchor housing, wherein the pivot includes a pivotal housing and the other of the two stop surfaces or the stop member internally contained within the pivotal housing, wherein the stop member is positioned between the stop surfaces and pivots relative to the stop surfaces through an angular motion limited by contact with the stop surfaces to define the storage and use positions of the wall, and wherein with the stop surfaces and the stop member internally contained within their respective housings there are no exposed gaps between the stop surfaces and the stop member that get closed in a pinching manner when folding and unfolding the walls.
