  • Patent number: 4750733
    Abstract: Aquatic amusement device comprising a canvas held in an inflated configuration by a pneumatic overpressure inside a closed space under the canvas. The canvas has a top and a periphery and a trench full of water is provided along the canvas periphery. A support structure extends from the closed space up through the canvas supporting the canvas in the inflated configuration, with the canvas being supported in air-tight suspension from a suspension point some distance up the support structure. A water discharge device is provided on top of the support structure for directing water onto the canvas, and a water circulator is provided for circulating water from the trench in and under the canvas and along the support structure to the water discharge device. In this way, water exiting from the water discharge device flows by itself over the canvas back to the trench.
