摘要 |
An apparatus for rotating a shaft about an axis of rotation less than one full revolution. The apparatus comprises a crank attachable to the shaft; a first link pivotally attached to the crank, the first link having a first attachment point; and a first stop for preventing rotation of the first link about the crank when the shaft is rotated in a first direction from a neutral position. A force applied to the first attachment point has a lever arm to the axis of rotation that lengthens as the shaft is rotated from the neutral position in either clockwise or counter-clockwise direction. |
