Patent ID: 8161841

Claim:
A cable operating mechanism comprising: a fixed member; a wire takeup member rotatably mounted with respect to the fixed member in first and second rotational directions on a rotational axis with the second rotational direction being opposite the first rotational direction; an operating lever pivotally mounted with respect to the fixed member on a pivot axis that is parallel to the rotational axis; and a movement transmission arrangement operatively coupling the operating lever to the wire takeup member to transmit pivotal movement of the operating lever to rotational movement of the wire takeup member in the first rotational direction such that the wire takeup member has a greater amount of angular displacement than an angular displacement of the operating lever in response to the pivotal movement of the operating lever, the movement transmission arrangement including a first gear fixed to rotate with the operating lever, a second gear meshed with the first gear, a third gear rotated by the second gear, and a fourth gear meshed with the third gear, with the fourth gear being fixed to rotate with the wire take up member.
