  • Patent number: 8746808
    Abstract: A bicycle rim is provided with an annular tire mounting part, an annular spoke mounting part, at least one spoke attachment member and an orientation maintaining structure. The annular spoke mounting part includes a plurality of spoke openings a circumferential spaced along the annular spoke mounting part. The spoke mounting part extends from the annular tire mounting part to define an interior space containing the spoke attachment member. The orientation maintaining structure is dimensioned with respect to the interior space to form an orientation maintaining arrangement such that the spoke attachment member is slidably disposed within the interior space in a circumferential direction of the bicycle rim to selectively align with one of the spoke openings while also maintaining an orientation of the spoke attachment member within the interior space to align with the one of the spoke openings.

  • Patent number: 6718844
    Abstract: A bicycle shift control device comprises a base member for attachment to the bicycle, a operating member rotatably supported relative to the base member for rotating in first and second directions, a transmission control member rotatably mounted relative to the base member for controlling the pulling and releasing of a transmission control element, a bracket for supporting a transmission control element diverting surface, and an intermediate member coupled for rotation with the transmission control member. The intermediate member rotates around a first axis, and the intermediate member can move in the direction of the first axis between an engagement position, in which the intermediate member engages the bracket, and a disengagement position, in which the intermediate member is disengaged from the bracket.

  • Patent number: 6595894
    Abstract: A shift control device for a bicycle is disclosed having a planetary gear assembly for varying the relative angular position between an actuating member and a control member. In a preferred embodiment of the invention, the shift control device includes a control member engageable with a ring gear to drive a plurality of planetary gears about a fixed base member. The fixed base member preferably includes a sun gear integrally attached thereto. The planetary gears are preferably carried by an actuating member configured to pull and release a bicycle shift cable. Rotation of the planetary gears results in the tension or release of the bicycle shift cable. The shift control device can include a positioning mechanism for controlling the position of the actuating member relative the base member.
