Patent ID: 7918768

Claim:
A pedal assembly comprising: a pedal, and a crank arm having an axis of rotation; and a variable attachment device that attaches said pedal to said crank arm at an angle of inclination with respect to said axis of rotation of said crank arm, wherein said variable attachment device comprises a rotating part to which said pedal is attached, said rotating part being rotatably attached to a point on said crank arm distanced along a longitudinal axis of said crank arm from said axis of rotation of said crank arm, said rotating part being rotatable about a rotation axis which is generally perpendicular to said axis of rotation of said crank arm and generally perpendicular to said longitudinal axis, and wherein rotating said rotating part about said rotation axis relative to said crank arm changes said angle of inclination with respect to said axis of rotation of said crank arm, and wherein an angle of said pedal with respect to a horizontal ground surface changes during pedaling of said pedal about said axis of rotation of said crank arm.
