ABSTRACT:
A pneumatically elevating recreational exercise device that utilizes in its preferred embodiment a commercially manufactured air cylinder (12) as an extendable air spring that is secured, or fixed to a horizontal surface or stand. A safety harness attachment (51) for securing a body harness is also provided. The device produces dramatic extension, or elevating capacity for vertical rebounding movement, and is entirely self-contained. An aspirating check-valve (10) is used to admit air at the top of the stroke, which produces added elevation with each vigorous leaping effort. This concept is also applied to an unsecured toy pogo stick embodiment.
