Abstract

An exercise machine with a seat and two adjustable cranking mechanisms is disclosed. The first cranking mechanism has rotatable hand grips for grasping by the user's hands while the second cranking mechanism has rotatable pedals for engagement by the user's feet. This second cranking mechanism is located at a position vertically above the location of the seat. Therefore, the exerciser may not use his or her body weight when exerting pressure on the pedals. This machine exercises virtually all of a user's muscle groups, however, the configuration of the seat vertically below the second crank mechanism results in a particularly strenuous activity for a user's hamstrings. Additionally, each cranking mechanism is selectively adjustable to a plurality of exercise positions. This makes the machine adaptable to all exercisers regardless of their size and shape and permits the user to selectively vary the exertion required during the exercise.

Claims18

Dependent claims

An exercise apparatus comprising:

a body having an upper portion and a lower portion joined to said upper portion;
a first crank mechanism rotatably attached to said upper portion, said first crank mechanism having a first rotatable main shaft defining a first horizontal axis of rotation and a first pair of moment arms each attached to opposite ends of said first rotatable main shaft, said first pair of moment arms having a first pair of throws, each one of said first pair of throws being attached to one of said first pair of moment arms;
and
a second crank mechanism rotatably attached to said lower portion, said second crank having a second rotatable main shaft defining a second horizontal axis of rotation and a second pair of moment arms attached to opposite ends of said second rotatable main shaft, said second pair of moment arms having a second pair of throws, each one of said second pair of throws being attached to one of said second pair of moment arms;
said second horizontal axis of rotation being located vertically above said seat;
at least one of said first and second crank mechanisms having means for adjusting the length of a said respective rotatable main shaft for providing axial adjustment.

An exercise apparatus comprising:

a body having an upper portion and a lower portion pivotally joined to said upper portion;
means for selectively varying the distance between said upper portion and said lower portion;
a seat slidably attached to said lower portion along a horizontal direction, said seat having a seat back;
a first crank mechanism rotatably attached to said upper portion, said first crank mechanism having a first rotatable main shaft defining a first horizontal axis of rotation, and a first pair of moment arms each attached to opposite ends of said first rotatable main shaft, and a first pair of throws, each one of said first pair of throws being attached to one of said first pair of moment arms;
a second crank mechanism rotatably attached to said lower portion, said second crank having a second rotatable main shaft defining a second horizontal axis of rotation, and a second pair of moment arms attached to opposite ends of said second rotatable main shaft, and a second pair of throws, each one of said second pair of throws being attached to one of said second pair of moment arms, said second horizontal axis of rotation being located vertically above said seat;
and
means for adjusting the length of at least any one moment arm of said first and second moment arms;
each of said first and second crank mechanisms having means for adjusting the length of a said respective rotatable main shaft for providing axial adjustment.
