Abstract:
1. Apparatus for bi-directional exercise movements having an incrementally set resistance, comprising: a main frame including a substantially horizontal pivot axis; a seat mounted on the main-frame; a sub-frame pivotally mounted on the main-frame to pivot through an angular range about the horizontal axis, the sub-frame including a pair of spaced apart, symmetrically inclined, right and left pivot axes lying in a plane in a plane of the horizontal axis and axially displaced therefrom to provide a moment arm thereabout; right and left lever arms having first and second ends wherein each first end is connected to the sub-frame for pivotal movement about the respective right or left pivot axis; linkage members connecting each lever arm to the main-frame so that, as the sub-frame pivots through its angular range, the right and left lever arms each pivot through a similar range; and the lever arms each further including a pedal, oriented to effect pivotal movement of the sub-frame about the horizontal axis, and a knee pad, oriented to effect pivotal movement of the lever arms about the right and left axes, so that force applied to either a pedal or a knee pad will move the sub-frame and lever arms through their respective angular ranges.
