Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
An exercise apparatus comprising: a stationary support; a platform mounted upon said support for reciprocating rotating motion and adapted to support a person; an upstanding post mounted forward of the perimeter of said platform and pivotally supported by said support for enabling the upper end of said post to undergo reciprocating motion in a direction generally toward and away from said platform, and means which include a slide mounted for reciprocating linear motion, said slide coupled by pin and groove means at one end to said platform and coupled at the opposite end to the lower end of said upstanding post, for causing said upper end of said post to undergo said reciprocating motion responsive to reciprocating rotating motion imparted to said platform.
Claim 2
Dependent Claim
123 words
