    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.

    Abstract: A bicycle shift operating device is provided for operating a shifting device to move a chain between two gears using a guiding portion. The bicycle shift operating device has an operating member, a moving member and a positioning mechanism. The positioning mechanism selectively maintains the moving member in a first position that locates the guiding portion to a first guiding position corresponding to the first gear, a second position that locates the guiding portion to a second guiding position corresponding to the second gear, and a third position that locates the guiding portion to a third guiding position corresponding to the second gear. The third guiding position is farther from the first guiding position than the second guiding position. The positioning mechanism moves the moving member from the first position to the second position in response to a single operation of the operating member.

  • Patent number: 8276477
    Abstract: A control device such as a handlebar-mounted brake includes a support structure containing a hydraulic piston, a lever pivotally connected to the support structure by a pin, and a transmission element for transmitting force from the lever to the piston during a normal actuation stroke of the lever. The lever may pivot outward substantially beyond its normal rest position. A torsion spring biases the lever in the actuation direction so that the lever and the transmission element are normally in contact. However, in the event of a fall, the lever can pivot outward from its normal rest position, out of contact with the transmission element. The hydraulic components are thereby protected from damage, as the pin and support structure bear the entire impact force applied to the lever.

    Abstract: A bicycle shift operating device basically comprises a bracket, a shift lever and a shift operating unit. The bracket includes a grip section having a lateral side with a shift cable guide portion. The lateral side faces towards a bicycle longitudinal center plane when the shift operating device is in an installed position. The shift lever is pivotally mounted to the bracket. The shift operating unit is mounted on the bracket. The shift operating unit includes a spool. The spool is rotated in a rotational plane in accordance with movement of the shift lever to wind a shift cable extending from the spool to the lateral side. The shift cable guide portion is arranged at the lateral side of the bracket such that the shift cable guide portion guides the shift cable along a guiding direction that is non-parallel to the rotational plane of the spool.

  • Patent number: 8096208
    Abstract: A positioning apparatus for a shift control device for a bicycle transmission comprises a movable member having a positioning element, a positioning member having a positioning element structured to engage the positioning element of the movable member, and a biasing member that biases the positioning member towards an engaged position wherein the positioning element of the positioning member engages the positioning element of the movable member. The positioning member moves toward and away from a plane of movement of the movable member. A releasing member is disposed between the movable member and the positioning member, wherein the releasing member moves between an initial position and an operating position. The releasing member allows the positioning member to be in the engaged position when the releasing member is in the initial position, and the positioning member moves to the disengaged position when the releasing member moves to the operating position.

  • Patent number: 8069749
    Abstract: A shift control apparatus for a bicycle comprises an output transmission member that moves to at least a first output position and a second output position, a position maintaining mechanism, and a release control mechanism. The position maintaining mechanism includes a position maintaining member that moves between a position maintaining position and a position release position, wherein the position maintaining position maintains the output transmission member in one of the first output position and the second output position. The position release position allows the output transmission member to move toward the other one of the first output position and the second output position. The release control mechanism includes a release member that moves between a first release member position and a second release member position.

  • Publication number: 20110290064
    Abstract: In a parking brake system, a locking tooth (17a) of a ratchet plate (17) is configured to have: a first area (S1) in which a locking claw (19c) of a ratchet pawl (19) comes into contact with the locking tooth and remains there in an equilibrium state when a parking brake lever is pulled up and thereafter loosened while a release rod being pressed; and a second area (S2) in which the locking claw remains there in a state of halfway engagement of tooth tips when a pressing force of the release rod is released. With this configuration, when the locking claw (19c) comes into contact with a portion closer to a tip of the locking tooth (17a) beyond the first area (S1), a line of force (F1) is maintained due to the pressing force of the release rod. Accordingly, the locking claw (19c) does not become in the state of halfway engagement of tooth tips at the second area (S2), and the locking claw (19c) slides towered the tooth tip to prevent beforehand the occurrence of the state of halfway engagement of tooth tips.

  • Patent number: 8061233
    Abstract: A method for carrying out gearshifting of a bicycle derailleur through an actuation device is described that utilizes a mobile mechanical member to control the derailler. Every gearshifting operation corresponds to a movement of predetermined amount of the mobile member. The method is carried out by the steps of an active initial movement of the mobile member for a first amount equal to only a portion of the amount of the movement corresponding to gearshifting; and an automatic final movement of the mobile member for a second amount equal to the remaining portion of the amount of the movement corresponding to gearshifting. Devices capable of implementing such a method are also described.
