Years back we had a trailer with (tip outs) and they actually were tip outs. They were hinged on the bottom and you had to physically lift them from the outside, and somebody had to be inside to catch them and let them down on the floor gently.

By the way, I deleted your other post. It was a duplicate to this one. Only need one, somebody will see it and answer if they can help.
