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.
A recreational device for producing the thrill of a free fall on the users and comprising in combination a housing having a bottom, tall side walls and an open top, a shock absorbing cushion extending throughout the area of the bottom of said housing, an inwardly extending peripheral deck at the open top of said housing, a plurality of elastic bands having their two ends fixed on the interior surface 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 said housing cannot fall all the way down without bouncing on one or more of said elastic bands prior to reaching said shock absorbing cushion, said elastic bands being arranged throughout at least a substantial part of the height of said housing, a frame, at least part of said plurality of elastic bands form a horizontal net within said frame, and hoist means engage said frame for moving the same up and down the side walls of said housing.
A recreational device for producing the thrill of a free fall on the users and comprising in combination a housing having a bottom, tall side walls and an open top, a shock absorbing cushion extending throughout the area of the bottom of said housing, an inwardly extending peripheral deck located at the open top of said housing, said deck having an area sufficient to accommodate a predetermined number of persons and including a launching area for allowing said persons to jump into said housing, and a plurality of elastic bands having their two opposite ends fixedly attached to the interior surfaces of the side walls of said housing, each individual elastic band extending in a horizontal position throughout its length across said housing, said elastic bands being randomly arranged at different levels within said housing to form an elastic network leaving spans between said bands which are sufficiently small to prevent a person jumping from said deck into said housing from passing through said elastic network all the way down through said housing except by bouncing on one or more said elastic bands, said elastic bands having an elasticity sufficient to permit said persons to rebound thereon as they fall from a higher level of bands to a lower level of bands, said elastic bands being arranged throughout at least a substantial part of the height of said housing.
