<p>A recreational device for producing the thrill of a free fall on the users, which comprises a housing, a shock absorbing cushion throughout the bottom of said housing, an inwardly extending peripheral deck on the top of said housing, and a plurality of elastic bands having their two ends fixed on the interior of the side walls of said housing, each individual elastic band extending in a horizontal position across said housing, said elastic bands being randomly arranged within said housing such that a person jumping from said deck into the housing cannot fall all the way down without bouncing on one or more of said elastic bands prior to reaching said shock absorbing cushion. A part of said elastic bands may be arranged in the form of horizontal nets fixed on a frame which may be moved upwardly and downwardly to increase or decrease the vertical distance between successive elastic bands, Said frames may also be made circular and the housing correspondingly be made cylindrical to permit rotation of said frames.</p> |
