But, from designes I've seen of antiquity pieces that would do that are basically... you create a piece that will be the pin socket and the guide as one tublar piece... then cut diagonally across it at an angle.
You use half of it as your socket, which is locked to the mounted structure. The other half is locked to the pin of the hinge. So when the door swings open, it raises on the diagonal. When let go, the weight pushes it along the diagonal to where it fits together (in it's original setting, which is it's lowest position).
Did that description make sense to you? That is old-school antiquity engineering, using just gravity to self-close. Fairly simple design and will work for years on end. I don't remember exactly where I saw those fittings... but I'm thinking it was on old-west styled (mid-1800's) swinging Saloon Doors... And on Victorian period swinging kitchen doors.
