Complex (impossible?) mechanism movement mating combination.. How can I achieve a bar linkage track system?

Hi,

 

I am a final year industrial design student trying to achieve an extension mechanism that uses bar linkages that hold when flat but pivot (80 degrees) when the following part goes around the corner of the track it is following. I have tried combinations of hinge joints with path followers but have had no luck for weeks now. No tutorials explain how to achieve such a complex mechanism. Any advice or even ways to cheat (I tried using a hidden invisible slot track but this didn't work either) would save my project pretty much.

Ah thank you but unfortunately this is not how the mechanism needs to work.. the 'carts' and 'slats' cannot overlap at all. They should be running freely driven by the bar linkages. I have had an idea of a simplified version but it is a shame that the mechanism I need is not possible in solidworks...

 

thanks again

Fabia,

 

sorry for that one. I was only demoing the Surface approach.

 

Here is another set of files with the linkage between them. And like before I did not finish it for you. The only thing that I did in addition to before was more of the same.

 

What do you say about this one ?
