Invention 50: Belt Buckle

This is an invention which I have used daily for years. It works, and it works well. Instead of a belt buckle, imagine this: The holes of the belt are horizontal slits instead. The buckle prong rotates (like a propeller), and is designed to enter a slit. Push the buckle prong into the desired slit, and turn it. I hope that makes sense! OBSERVATION: One can add a refinement. One so designs the slit and prong that pressure on the belt causes the prong to turn, and stay in place. The prong incidentally has a double function. A belt buckle keeps the leather from curling. The prong largely prevents such curling, too. Personally, I find this invention to work better than the common belt buckle.
