  • Patent number: 10689060
    Abstract: A bicycle operating device is basically provided with a support structure, a first release member, a second release member and a select member. The first release member is movably supported on the support structure between a first non-releasing position and a first releasing position. The second release member is movably supported on the support structure between a second non-releasing position and a second releasing position. The select member is movably supported on the support structure between at least a first select position and a second select position. The select member permits movement of the first release member and prevents movement of the second release member while the select member is in the first select position. The select member permits movement of the second release member and prevents movement of the first release member while the select member is in the second select position.

  • Patent number: 9381975
    Abstract: A bicycle shift operating device is basically provided with a base member, a shift unit, a first operating lever, a second operating lever, a first biasing element and a second biasing element. The first operating lever operates the shift unit by pivoting about a first pivot axis between a rest position and a shifting position. The second operating lever operates the shift unit by pivoting about a second pivot axis on the first operating lever between a rest position and a shifting position. The first biasing element biases the first operating lever towards the first rest position to keep the first operating member at the first rest position. The second biasing element biases the first operating lever towards its rest position in response to independent movement of the second operating lever from its rest position to its shifting position while the first operating lever remains at its rest position.

  • Patent number: 8752450
    Abstract: A bicycle component operating device is provided with a base member, an operating lever and an operating unit. The base member includes an insertion opening that is provided on one of a top surface and a bottom surface of the base member to provide access to an interior space within the base member. The operating lever is pivotally mounted on the base member about a first pivot axis extending transverse to the lateral surfaces. The operating unit is disposed in the interior space of the base member. The operating unit has a dimension relative to the insertion opening such that the operating unit is insertable into the interior space of the base member through the insertion opening. The base member is configured such that the insertion opening continuously extends from the first pivot axis toward the first end and the second end with respect to the first pivot axis.

  • Patent number: 8746106
    Abstract: A bicycle operating device operates a bicycle component by moving a winding member that moves a take-up member relative to a fixed member in first and second directions. A positioning member is movably arranged with respect to the fixed member between a non-holding position and a holding position to selectively engage a positioning ratchet that is fixed to the take-up member. In the holding position, the positioning member prevents the take-up member from moving in the second direction by selectively engaging one of at least three engaging portions of the positioning ratchet. A preventing member is movably arranged with respect to the positioning ratchet such that the preventing member prevents the positioning member from engaging an intermediate engaging portion of the positioning ratchet while the winding member moves the take-up member in the first direction.

  • Patent number: 8534156
    Abstract: A bicycle shift operating device is basically provided with a pair of operating members and a take-up member. The take-up member pivots in opposite rotational directions in response to movement of the first and second operating members. The first operating member pivotally supports a pawl member having first and second pawls. The first pawl selectively engages and moves one of a release member and a pulling ratchet in response to the movement of the first operating member. The second pawl selectively engages and moves other of the release member and the pulling ratchet in response to the movement of the second operating member. An abutment portion of the first operating member selectively contacts an abutment portion of the pawl member such that the pawls pivot when one of the first and second operating members is operated.
