Wagon with latch system for collapsible walls

摘要

A collapsible wagon includes a base and one or more 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 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 one of the walls to another one of the walls 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 wagon for cargo, comprising:
a base; at least one first wall that extends generally upright from the base in a use position to help hold the cargo, wherein the 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 latch system including first and second latches and an actuator operably coupled to the first and second latches, each of the first and second latches including a first latch member and a respective second latch member that releasably secure to each other, wherein the first latch members are movable between a locked position and an unlocked position, each first latch member in the locked position is secured to the respective second latch member so that the movable wall is secured in the upright use position, and each first latch member in the unlocked position is released from the respective second latch member so that the movable wall is free to move to the collapsed storage position, wherein the first latch members are positioned at opposite ends of the movable wall, the actuator is positioned on the movable wall, and the second latch members are positioned on the wagon on at least one element of the wagon other than the movable wall and positioned to engage with the respective first latch members in the locked position when the movable wall is in the upright use position, wherein the first latch members are spring-biased toward the locked position, and wherein operation of the actuator moves the first latch members from the locked position to the unlocked position so that both the first and second latches are unlocked simultaneously by operation of the actuator to release the movable wall for movement from the upright use position to the collapsed storage position.
