  • Portable exercise device providing constant force output
    Patent number: 9358420
    Abstract: The exemplary embodiments herein provide an exercise device having a frame, comprising a first and a second arm, a first end of each arm meeting in fixed angular relationship at a vertex and a second end of each arm extending away from the vertex; a lever arm, having a first and a second end, the first end constrained to rotate about a pin located near the vertex; and a resistance arrangement, configured to convert rotation by a user of a first rotational assembly about an axis on the second end of the first arm into rotation of a second rotational assembly about an axis on the second end of the lever arm, which is converted into rotation of a third rotational assembly about an axis on the second end of the second arm, with the rotation of the third rotational assembly being resisted by a resistive element, the resistance arrangement providing a substantially constant resistance against the rotation of the first rotational assembly by the user over the entire range of the rotation.
