Implement wing frame folding apparatus with automatically pivoted biased latch

In a mobile machine, an implement wing frame folding apparatus with automatic lock-up and float capability comprising:

• a main frame;
• a wing frame pivotally connected to said main frame and movable about a pivot axis thereof between a raised position and a lowered ground engaging position, said wing frame having a striker pin offset from the pivot axis of said wing frame;
• latch means pivotally mounted directly to said main frame engaging said striker pin in an engaging position to latch said striker pin when said wing frame is in said raised position;
• biasing means on said main frame biasing said latch means toward said engaging position;
• said latch means comprising a cam follower surface engageable by said striker pin to pivot said latch means away from said engaging position when said wing frame is moved toward said raised position whereby further movement of said wing frame to said raised position effects disengagement between said cam follower surface and said striker pin and automatic movement of said latch means to said engaging position under the influence of said biasing means;
• a float bar having first and second ends with said first end pivotally connected to said wing frame;
• actuating means pivotally connected to and between said main frame and said float bar second end for selectively moving said float bar to pivot said wing frame between said lowered and raised positions;
• and
• a first engaging member on said float bar automatically pivoting said latch means to release said striker pin responsive to operation of said actuating means to lower said wing frame from said raised position.
