ABSTRACT:
A form of trampoline apparatus for use in connection with tumbling and the like employs a relatively long-narrow bed resiliently suspended between a pair of side rails only so that the two opposite ends of the bed are unobstructed by any cross rails or other structure. The two rails are supported above the floor by a substructure which interconnects them and holds the rails apart against the tension of the bed. One end of the bed inclines upwardly toward the remainder of the bed which is horizontal with respect to the floor. The trampoline is narrower relative to its length and having dimensions such that the length is substantially three times or more its width to provide directional rebound characteristics.
