发明名称 Recreational device for producing the thrill of a free fall
摘要 A recreational device for producing the thrill of a free fall on the users, which includes a housing, a shock absorbing cushion throughout the bottom of the housing, and an inwardly extending peripheral deck on the top of the housing. The deck has an area sufficient to accommodate a predetermined number of persons and arranged to provide a launching platform for allowing persons to jump into the housing. A plurality of elastic bands have their two opposite ends fixedly attached to the interior surfaces of the side walls of the housing, each individual elastic band extending in a horizontal position throughout its length across the housing. The elastic bands are randomly arranged at different levels within the housing to form an elastic network leaving spans between the bands which are sufficiently small to prevent a person jumping from the deck into the housing from passing through the network all the way down through the housing without bouncing on one or more of the elastic bands, but with the elastic bands having an elasticity sufficient to permit persons to rebound on them as they fall from a higher level of bands to a lower level of bands. The elastic bands are arranged throughout at least a substantial part of the height of the housing. A part of the 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. The frames may also be circular and the housing correspondingly cylindrical to permit rotation of said frames.
