Abstract
The water trampoline includes a generally doughnut-shaped inflatable tube having an open center area. A mesh rebound member extends over the open center area and is secured around its entire periphery to the tube on the upper surface of the tube member. The attaching/securing elements include a plurality of side-by-side loop elements which extend toward the open center area of the tube from the upper surface thereof and a plurality of side-by-side loop elements which extend from the periphery of the rebound member. A first cord extends through the loop members, alternately between alternate tube loop members and rebound element loop members. A second cord member extends through the loop members through which the first cord does not extend. The cord members are tightened, moving the loop members together endwise.
