Hi again everyone.
I've tried everywhere on the net to try and find a solution to my problem but I guess
not knowing how to ask the question may be why I couldn't find anything. I'm hoping
there are some engineers amongst you who can see a solution straight away.
My problem is I have a simple lifting mechanism consisting of two levers and a bracket
to which is attached a large flat surface. As the lower arm is raised upwards, I want the
flat surface to always be parallel to the fixed arm. Here is a diagram of what I mean:

And here are some pic's of the actual mechanism. The small bracket on the end of the
swing arm carries the flat surface and this surface will cover the entire mechanism
leaving about 3mm clearance.

I'm sure there is a simple way to do this, I just can't get my head around it.
Your help would be appreciated. :)
