Upfolding mechanism

Hey there,

I'm a beginner of using rhino and grasshopper, and I try to build a stand for a fair.

The idea behind is to have a changeable stand with rods you can fold and unfold.

I Need to do this for my architecture studies and so i thought some of you might have an idea how I could do this in an efficient way.

i have got some simple paper models, this is way it should be like.

THANKS for help, Folks!
