Breakaway rim While several men claim to have created the breakaway rim, Arthur Ehrat is recognized as the inventor by the Smithsonian Institution's Lemelson Center for the Study of Invention & Innovation.[1][2] A resident of Lowder, Illinois, Ehrat worked at a grain elevator for most of his life and barely knew anything about basketball. In 1975, his nephew, an assistant basketball coach at Saint Louis University, asked him to help design a rim that could support slam dunks. Using a spring from a John Deere cultivator, Ehrat designed a rim that could bend and spring back after 125 pounds of force were applied to it. He called his device "The Rebounder". In 1982, he was awarded a patent for his invention, which was officially called a "deformation-preventing swingable mount for basketball goals".[3]
