US Patent 10532238 Rebounding apparatus with tensioned elastic cords

A trampoline with a frame has a rebounding mat that is tensioned to the frame with a plurality of flexible and cordlike linear elastic members. Preferably each cordlike elastic member is connected to the frame and the rebounding mat at one of two alternative positions to alter the tension. The alternative positions permit a tensioning process that extends the lifetime of elastic cords having a fabric sheath. This independent tension of each elastic member is via connector member that grips the rebounding mat but also grasps opposing the ends of the elastic members as well as central portion thereof so that two segment of the cord between each end and the central portion are preferably wrapped around the trampoline frame.
