Rigging a machine - parallel movement required.

I have been trying to rig a model of a machine. The machine has 4 hinges - one in each corner so it can move as a parallelogram. I can’t get one of the bones to follow correctly. I’m sure its simple parenting type issue, but I have always had trouble rigging things . HInts appreciated.

Note -the bone on the right is supposed to follow the one on the left

From your pictures, I can’t really see what is supposed to move and what is not. However I think something like this solution might work for you in variations.

Perfect, just what I was looking for, Thanks

Can someone now add to this thread a brief description of what the problem was, and what the solution was?
