Abstract
Height-adjustable apparatus using a spring to urge forward and rearward undulating whippy locomotion. A hand-crawling embodiment enables users to engage in all-fours crawling locomotion while the body is conventionally situated in a two-legged orientation. A foot-bounding embodiment enables walkers, joggers, runners and jumpers to engage in forward and backward whippy locomotion. A crutch embodiment enables crippled or injured users to likewise engage in whippy locomotion.
Claims17
A hand-crawling apparatus having a pair of hand-crawling members for enabling a user having particular weight and height attributes to engage in whippy locomotion, with each hand-crawling member thereof comprising:
- a hand-glove assembly having a planar hand-platform member with a top surface and a bottom surface;
- a hand-embracing member affixed to said top surface of said planar hand-platform member;
- a cylindrical post assembly affixed at one end thereof to said bottom surface of said hand-platform member having a cylindrical post member projecting perpendicularly therefrom and downwardly thereof, with external threads circumferentially disposed upon said cylindrical post member;
- a base assembly comprising a cylindrical housing member with an axially disposed central whorl hole with internal threads sized to mate with said external threads of said cylindrical post member at one end thereof, and threadedly attached to said cylindrical post member;
- and
- said base assembly having a replaceable spring member disposed immediately below said cylindrical housing member and secured in a substantially vertical position between a first retainer member affixed thereto at one end of said replaceable spring member and a second retainer member therebelow affixed to a substantially planar base plate member at the other opposite end of said replaceable spring member.
