How a Gymnast's Dream Became America's Favorite Backyard Invention
George P. Nissen Tumbling Device Patent Print, 1945
In 1945, as the Second World War wound toward its end, a young trampolinist named George P. Nissen filed a patent for something that would transform recreational fitness in America. His invention was elegantly simple: a canvas bed stretched taut across a steel frame, designed to launch the human body skyward with minimal effort. The Patent Office granted him U.S. Patent US2370990 on March 6 of that year, and with it, Nissen secured his place in the history of American play.
Nissen had been tinkering with the concept since the late 1930s, inspired by the safety nets used by circus performers. He called his creation a "tumbling device," though the world would soon know it by a more poetic name: the trampoline. What makes his original patent drawing so compelling is its clarity, its confidence. The technical figures, the carefully labeled components, the measured border, and the official signatures all speak to the seriousness with which Nissen approached his whimsical invention. This wasn't a lark; it was engineering in service of joy.
The timing was perfect. Post-war America was hungry for new forms of recreation, for backyard entertainment, for ways to let children burn energy and feel weightless. Nissen's patent drawings capture that moment of innovation, when an idea moves from sketch to official recognition. Every line on the Patent Office sheet tells a story of ambition and ingenuity during an era when individual inventors could still change the landscape of American leisure.
Our museum-quality giclée print preserves every detail of the original patent composition on warm, 325gsm archival matte paper. The technical rendering glows with renewed clarity against the neutral ground, and the measured border remains untouched. Whether framed in Slimwood Silver, Slimwood Gold, or Satin Black, this piece invites viewers to appreciate the draftsmanship and vision that launched millions of children into the air.
