Wagon with minimized-play collapsible wall

摘要

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.

主权项

1. A wagon for cargo, comprising:
a base; at least first and second walls that extend generally upright from the base in a use position to help hold the cargo, wherein the second wall is movably mounted to the base and moves relative to the base between the upright use position and a storage position collapsed into a compact arrangement; and a minimized-play feature including at least one ramped surface on one of the first and second walls, an interference between the first and second walls, and a resilient deflection feature of the first wall, wherein when the second wall is moved from the collapsed storage position toward the upright use position, the first and second walls interfere with each other, the ramped surface of the first or second wall slidingly engages the other one of the first and second walls to generate a lateral displacement force, the first wall is resiliently displaced generally laterally by the lateral displacement force as permitted by the resilient deflection feature to provide clearance for the second wall to move into the upright use position, and the resilient displacement of the first wall generates a compression force on the second wall in the upright use position so that the first and second walls are held together tightly under pressure to prevent wiggling relative to each other.
