Here's a couple more close-up photos that I have. Hopefully the top-down shot clarifies how it works:
I started with this hinge from Lowes. I've replaced the normal hinge pin with the plastic handled 1/4" quick-release pin from McMaster that I had lying around from another project. I cut the hinge down to only using three "barrels", to match the length of the pin that I had. One half of the hinge is attached to the right angle bracket riveted to the door. The other half is screwed into holes drilled/tapped in the block you see welded to the rack. By pulling the pin, the "over hinges" will pivot around (parallel to the normal path of the door), but separated from the door. There's a bit of interference at about 30° opening, since my over hinges don't stick out quite enough to clear the "corners" of the main door hinge (look close at yours, you'll see what I mean). If I were doing it again, I'd experiment with making the hinges a bit longer so they cleared this, but when I originally made them, I was trying to keep everything tight to the door.
I'll try to get a photo with the pin pulled and the rack swung out slightly, that should clear up any questions.
