I’m designing a laser-cut jewelry box for Genevieve, and one of the features I’m hoping to integrate is a cool hinge system that makes the lid sort of float back instead of just flap open. Basically imagine the trays you find inside of those unfolding tackle boxes, only with asymmetrical connection struts. I looked around the internet trying to figure out what this is called, but came up short. I can’t imagine I invented this – anyone have any leads on what this kind of construction is called?
Anyway, I’ve had a pretty clear idea of what I wanted for a few days now, but I was stuck puzzling over how to conceptualize all the trigonometry involved to predict the motion of the lid. I finally decided it wasn’t worth waiting for complete understanding and that I should just make a mockup instead. The video above is some cardboard and some #4-40 screws I had laying around thrown together with complete guesses for the dimensions.
To my surprise, it actually worked the way I hoped it would! I think I’ll be able to use this to connect the lid to the box with all laser-cut parts and possibly with no fasteners at all. Stay tuned for further details as I get farther into the design.
