Abstract
A conveyor includes a container and a cover. A plurality of upper latches each include an upper hook. A plurality of lower latches each include a lower hook. A plurality of brackets are fixedly attached to the container and are disposed along the container, where each bracket is configured to pivotally support each lower latch at a pivot point. A rigid linkage member couples the body portion of each lower latch. Urging in a first direction at any point along linkage member causes each lower hook to simultaneously disengage from the upper hook to unlock the cover. The pivot point is arranged such that the weight of the body portion and the linkage member cause the lower hooks to be urged against the upper hooks to lock the cover to the container, in the absence of a force applied to the linkage member in the first direction.
