Реферат: An over center closure apparatus for a spring latched rock door for a combine harvester includes a first, free rotating lever arm connected to rotate about the rock door pivot and a second lever arm connected to rotate with the rock door pivot. The second lever arm includes a stop positioned to engage the first lever arm as it rotates about the rock door pivot. A linkage arm extends from the first lever arm downward to a over center lever arm in an over center assembly. The over center lever arm is positioned to rotate about a pivot axis between an over center position and a free rotating position such that, when the over center lever arm is rotated to the over center position, the rock door is closed and held in the closed position by the over center position of the over center lever arm. The rock door can then be conveniently latched closed.
