Patent ID: 7331910

Claim:
An adjustable resistance physical rehabilitation and fitness exercise device comprising: a) a frame assembly for affixing to a platform comprising: i) forward and rearward irregular pentagonal uprights, each pentagonal upright consisting of two base angles and one upper vertex angle of 90° and a biased construction of the fifth leg of said pentagonal upright, and wherein said forward and rearward pentagonal upright are connected at each vertex with crossbars to form a three dimensional rectangular tower; ii) aligned machined ports having respective horizontal centerlines in oppositely disposed forward upper horizontal arm and rearward upper horizontal arm of said forward and rearward pentagonal uprights, respectively, within which friction reduction bearings are secured; iii) an index marker in line with said horizontal centerline of said machined port affixed to a frontal face of said forward upper horizontal arm of said pentagonal upright; iv) a bored port through said forward upper horizontal arm of said forward pentagonal upright oppositely disposed, along said machine port horizontal centerline, from said index marker to receive a locking pin to secure said adjustable lever assembly in place to facilitate isometric exercise regimens; and v) a bar longitudinally attached at the base of said frame assembly equidistant from oppositely disposed pentagonal uprights, said bar further comprising a clevis attached centrally on the upper surface thereof; b) an adjustable lever assembly having an axial centerline and being operatively connected to said frame assembly for movement by a user in clockwise and counterclockwise rotation about a fixed axis to perform specified exercise regimens; c) adjustable resistance controlled flow means to provide predetermined levels of resistance against movement of said lever assembly; and d) an adjustable seat and track assembly, operatively slidably and swivably connected to said frame assembly, for positioning said user in respect to the axial centerline of said lever assembly to perform predetermined exercise regimens.
