I hung a set of barn doors for my friend last year, and designed a latch to keep her dog from pushing the doors open and getting shoes out to chew on. (It ended up not being used because the weight of the doors meant the dog's evil intent was thwarted, ha ha!)

Picture just the barrel of a fairly large door hinge; notice the barrel is divided into three smaller loops; two loops are screwed onto the door and one loop screwed into the wall, and an easily removable pin keeps them 'meshed' in line. . I made the loops from copper sheet, I peened them with a hammer before I formed them for artistic interest, and the pin was a chrome steel thingy from some unknown device, about 8" long that was topped with a bit of forked tree branch, sanded, varnished and waxed, then attached to the wall with a length of fancy cord to keep it from getting lost when the door was open.

I've lost it because it didn't end up being used, and that's a shame, because it was really kind of cool!
