I am planning to build a motorized bed. I am still in the researching phase so I went to a bedroom shop in my city. In the shop I saw this hinge, or at least I believe it´s called a hinge. I have been researching it for 2 days now and I can't seem to figure out the name or type of hinge they used for this particular joint.
The only type of hinge I found similar was the Knife hinge, but that isn't quite what I am looking for.
