Abstract
A pedal crank has a throw adjuster comprised of two triangular frames in opposed relationship to a common triangular base that is variable in length. A pedal crank is formed with a peak of a proximal triangular frame attached to a crank axle and a peak of a distal triangular frame attached to a pedal axle. A fixed side of the proximal triangular frame is attached rigidly to the crank axle and a floating side of the proximal triangular frame is attached rotationally to the crank axle. A fixed side of the distal triangular frame is attached rigidly to the pedal axle and a floating side of the distal triangular frame is attached rotationally to the pedal axle. The fixed side of the proximal triangular frame and the fixed side of the distal triangular frame are attached to opposite ends of the common triangular base. Both sides of both triangles are attached pivotally to the common triangular base that is variable in length with a screw shaft, a fluid-operated cylinder, or other length-adjustment means. In an exerciser embodiment, the crank axle is in chain drive relationship to an electrical, fluid or frictional resistor of rotation that is variable in rotational resistance. A calibrator of throw length is positioned parallel to the common base.
