Abstract
Abstract The outer ends of the coil springs holding the trampoline bed are connected with rods arranged parallel with the edges of the bed so that the springs can automatically adjust their positions to maintain their directions at right angles to the bed, and the supporting rods also are utilized to position the cushions along the side of the bed to keep them from interfering with the springs.
