  • Patent number: 8161841
    Abstract: A cable operating mechanism basically has a fixed member, a wire take-up member, an operating lever and a movement transmission arrangement. The wire takeup member is rotatably mounted with respect to the fixed member in first and second rotational directions with the second rotational direction being opposite the first rotational direction. The operating lever is pivotally mounted in the first rotational direction with respect to the fixed member. The movement transmission arrangement is operatively coupling the operating lever to the wire takeup member to transmit pivotal movement of the operating lever to rotational movement the wire takeup member such that the wire takeup member has a greater amount of angular displacement than an angular displacement of the operating lever in response to pivotal movement of the operating lever in the first rotational direction.
