I've been pondering an idea for the Galley Hatch support for a while and would like to hear your input.

Let me try to describe...
It would consist of 2 round dowels hinged at the top, middle, and bottom. When the hatch is closed the support would be folded. When the hatch is open the dowels would line up straight and something like a small piece of pvc pipe would slide in place over the center hinge to lock the support in the upright position. To close the hatch you would simply lift the small piece of pvc pipe to allow the center hinge to fold.
If you think of your wrist, elbow, and shoulder as the support in the open "supported" position your arm would be straight above your head and the lock or piece of pipe would slide over your elbow to prevent it from bending.

I'm terrible with drawing... and I hoped I explained my idea well enough.
Would love to see what you all think...
Oh if someone has already come up with this can you link it for me?
