The electric perpetual portable trampoline was an invention that Doc Brown gave his son Jules to help him get exercise. In 1991, Jules used it to get Marty McFly out of a tree after he was chased up there by Doc's sick dog, Einstein.

Marty couldn't get off the trampoline until Doc pushed the button to disable it, after which it folded up, and Marty fell to the ground.
