Abstract

A bicycle operating device includes a base member coupled to a handlebar clamp and a user operated member movably coupled to the base member to move a mechanical control cable with respect to the base member. The base member includes a coupling portion coupled to the handlebar clamp. The coupling portion includes an elongated hole having a long direction extending parallel to a center axis of the handlebar clamp. The coupling portion is coupled to the handlebar clamp via a fastener extending into the elongated hole. The user operated member is movable with respect to the base member between a rest position and an operated position. The bicycle operating device does not mechanically fix a position of the mechanical control cable with respect to the base member in accordance with movement of the user operated member between the rest position and the operated position.

First claim

What is claimed is:

1. A bicycle operating device comprising:
a base member configured to be coupled to a handlebar clamp that is to be coupled to a bicycle handlebar; and
a user operated member movably coupled to the base member to move between a rest position and an operated position with respect to the base member to move a mechanical control cable with respect to the base member,
the base member including a coupling portion configured to be coupled to the handlebar clamp, the coupling portion being configured to directly contact an arcuate portion of the handlebar clamp, the arcuate portion of the handlebar clamp directly contacting the bicycle handlebar,
the coupling portion including an elongated hole extending in a longitudinal direction that extends parallel to a center axis of the handlebar clamp while the coupling portion is coupled to the handlebar clamp,
the coupling portion being configured to be coupled to the handlebar clamp via a fastener extending into the elongated hole, and
the bicycle operating device being configured not to mechanically fix a position of the mechanical control cable with respect to the base member in accordance with movement of the user operated member between the rest position and the operated position.

2. The bicycle operating device according to claim 1 , further comprising:
a pulling member movably mounted with respect to the base member about a mounting axis, the pulling member being operatively coupled to the user operated member to pull the mechanical control cable in accordance with an operation of the user operated member from the rest position to the operated position, the mounting axis being offset from the elongated hole of the coupling portion as viewed from a center fastening axis direction of the fastener.

3. The bicycle operating device according to claim 2 , wherein
the elongated hole includes a first end disposed adjacent to the mounting axis and a second end opposite to the first end in the long direction of the elongated hole,
the user operated member includes a proximal end located toward the base member and a distal end opposite to the proximal end, and
the proximal end of the user operated member is disposed between the first end of the elongated hole and the mounting axis as viewed from the center fastening axis direction of the fastener.

4. The bicycle operating device according to claim 2 , wherein
the elongated hole includes a first wall extending parallel to the longitudinal direction as viewed in the center fastening axis direction of the fastener, a second wall facing the first wall, a third wall connecting one end of the first wall and one end of the second wall, and a fourth wall connecting another end of the first wall and another end of the second wall, and
the pulling member is entirely offset from the first wall and the second wall as viewed in the center fastening axis direction of the fastener.

5. The bicycle operating device according to claim 1 , further comprising:
a pulling member configured to pull the mechanical control cable in accordance with an operation of the user operated member,
the user operated member includes a first part disposed nearest to the handlebar with the coupling portion coupled to the handlebar clamp, and
the first part being separated from a reference plane by a first distance that is greater than or equal to 6 mm, the reference plane extending in a center fastening axis direction of the fastener and passing through a center of the elongated hole along the longitudinal direction of the elongated hole.

6. The bicycle operating device according to claim 5 , wherein
the first distance is greater than or equal to 10 mm.

7. The bicycle operating device according to claim 5 , wherein
the first distance is less than or equal to 13 mm.

8. The bicycle operating device according to claim 5 , wherein
the pulling member includes a groove in which the mechanical control cable is wound, and
the reference plane is separated from a center of the groove with respect to a direction parallel to a mounting axis by a second distance that is greater than or equal to 14.2 mm.

9. The bicycle operating device according to claim 8 , wherein
the second distance is less than or equal to 22 mm.

10. The bicycle operating device according to claim 1 , wherein
the base member further includes a body coupled to the user operated member and a connecting portion connecting the body and the coupling portion, and
the connecting portion includes at least one of a recess and a through hole.

11. The bicycle operating device according to claim 10 , wherein
the connecting portion is shorter than the coupling portion in a direction parallel to the longitudinal direction of the elongated hole.

12. The bicycle operating device according to claim 10 , wherein
the connecting portion has a centerline with respect to a direction parallel to the longitudinal direction of the elongated hole,
the coupling portion has a centerline with respect to a direction parallel to the longitudinal direction of the elongated hole, and
the centerline of the connecting portion is offset from the centerline of the coupling portion toward the user operated member as viewed in a center fastening axis direction of the fastener.

13. The bicycle operating device according to claim 1 , further comprising:
a bearing rotatably supporting the user operated member with respect to the base member.

14. The bicycle operating device according to claim 1 , further comprising:
a cable fixing bolt configured to fix the mechanical control cable to the user operated member.

15. The bicycle operating device according to claim 14 , wherein
the user operated member further includes an internal threaded portion to which the cable fixing bolt is fastened and a cable groove formed adjacent an opening of the internal threaded portion for receiving the mechanical control cable, and
the cable groove includes a bent portion bent along the opening of the internal threaded portion.

16. The bicycle operating device according to claim 1 , further comprising:
a cable tension adjuster coupled to the base member.

17. A bicycle operating device comprising:
a base member configured to be coupled to a handlebar clamp;
a user operated member movably coupled to the base member to move a mechanical control cable with respect to the base member; and
a pulling member movably mounted with respect to the base member about a mounting axis, the pulling member being operatively coupled to the user operated member to pull the mechanical control cable,
the base member including a coupling portion configured to be coupled to the handlebar clamp,
the coupling portion including at least one coupling hole capable of adjusting a coupling position of the coupling portion in a first center axis direction of the handlebar clamp,
the coupling portion being configured to be coupled to the handlebar clamp via a fastener extending into the at least one coupling hole,
the at least one coupling hole defining a second center axis extending through a center of the at least one coupling hole and parallel to a first center axis of the handlebar clamp,
