| 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.

I claim:
1. An elevating rebounding exercise device or extendable pogo stick, comprising:
- (a) a pneumatic air cylinder to be used as an air spring by the method of utilizing stored energy in a compressed column of air to provide an outward biasing force, said air cylinder being vertically disposed, with barrel above and rod or plunger member protruding below, and having footrest means for a human operator located on the lower portion of said barrel; and
- (b) aspirating valve means connected to working air chamber of said air cylinder for the purpose of allowing the variation, during jumping efforts by the human operator, of the volume of air in said air chamber, thereby controlling the amount of lengthening or extension of said rod from said barrel, and the consequent elevation of said barrel along with said operator.
