Abstract

A bicycle operating device comprises a base member, a cable control body, a positioning pawl, a stopping member, and a stopping pawl. The positioning pawl is movable between a holding position to stop a movement of the cable control body in a first direction, and a non-holding position to allow a movement of the cable control body in the first direction. The stopping pawl is movable between a stopping position to stop a movement of the stopping member in the first direction, and a non-stopping position to allow a movement of the stopping member in the first direction. The stopping member is coupled to the cable control body such that the cable control body is movable relative to the stopping member within a movable range while the stopping pawl is arranged at the stopping position.

First claim

What is claimed is:

1. A bicycle operating device comprising:
a base member;
a cable control body movable relative to the base member in a first direction and a second direction that is different from the first direction, the cable control body including a positioning part;
a positioning pawl configured to engage with the positioning part, the positioning pawl movable between a holding position to stop a movement of the cable control body in the first direction, and a non-holding position to allow a movement of the cable control body in the first direction;
a ratchet gear movable relative to the base member, the cable control body, and the positioning part in the first direction and the second direction;
a stopping pawl configured to engage with the ratchet gear, the stopping pawl movable between a stopping position to stop a movement of the ratchet gear in the first direction, and a non-stopping position to allow a movement of the ratchet gear in the first direction, the ratchet gear being coupled to the cable control body such that the cable control body is movable relative to the ratchet gear within a movable range while the stopping pawl is arranged at the stopping position;
a biasing member arranged between the ratchet gear and the cable control body to bias the ratchet gear relative to the cable control body in the first direction;
a protrusion provided at one of the cable control body and the ratchet gear; and
a recess provided at the other of the cable control body and the ratchet gear, the protrusion being disposed and restricted to movement within the recess, the recess being dimensioned such that the protrusion is movable within the movable range in the first direction and the second direction.

2. The bicycle operating device according to claim 1 , wherein
the second direction is opposite to the first direction,
the cable control body includes a cable attachment part to which a control cable is attached,
the cable control body is configured to release the control cable when the cable control body is moved in the first direction, and
the cable control body is configured to pull the control cable when the cable control body is moved in the second direction.

3. The bicycle operating device according to claim 1 , wherein
the cable control body is rotatable relative to the base member about a main axis.

4. The bicycle operating device according to claim 3 , wherein
the positioning part includes positioning teeth configured to engage with the positioning pawl.

5. The bicycle operating device according to claim 4 , wherein
the positioning part has an outer periphery, and
the positioning teeth are provided on the outer periphery of the positioning part.

6. The bicycle operating device according to claim 3 , wherein
the ratchet gear is rotatable relative to the cable control body about the main axis within the movable range.

7. The bicycle operating device according to claim 6 , wherein
the ratchet gear is mounted on the cable control body.

8. The bicycle operating device according to claim 6 , further comprising:
a first operating member pivotable relative to the base member about a first operating axis in a first operating direction; and
a control member rotatable about the main axis in the second direction in response to a movement of the first operating member in the first operating direction such that the control member moves the positioning pawl from the holding position toward the non-holding position and moves the stopping pawl from the non-stopping position toward the stopping position.

9. The bicycle operating device according to claim 8 , further comprising:
a second operating member pivotable relative to the base member about a second operating axis in a second operating direction; and
a transmitting structure configured to transmit a pivotal movement of the second operating member in the second operating direction to the cable control body such that the cable control body is rotated in the second direction.

10. The bicycle operating device according to claim 6 , wherein
the ratchet gear includes stopping teeth configured to engage with the stopping pawl.

11. The bicycle operating device according to claim 10 , wherein
the ratchet gear has an outer periphery, and
the stopping teeth are provided on the outer periphery of the ratchet gear.

12. The bicycle operating device according to claim 1 , wherein
the positioning pawl is pivotable relative to the base member about a first pivot axis between the holding position and the non-holding position, and
the stopping pawl is pivotable relative to the base member about a second pivot axis between the stopping position and the non-stopping position.

13. The bicycle operating device according to claim 12 , wherein
the second pivot axis is spaced apart from the first pivot axis.

14. The bicycle operating device according to claim 1 , wherein
the ratchet gear is movably mounted on the cable control body within the movable range.

15. The bicycle operating device according to claim 1 , wherein
the biasing member is arranged between the protrusion and the recess so as to bias the ratchet gear relative to the cable control body in the first direction.

16. The bicycle operating device according to claim 1 , wherein
the cable control body includes a pulling part.

17. The bicycle operating device according to claim 1 , wherein
the ratchet gear is separate from the positioning part.

18. The bicycle operating device according to claim 1 , wherein
the ratchet gear includes an annular portion and stoppers configured to restrict movement of the cable control part within the movable range.

19. The bicycle operating device according to claim 1 , wherein
a protrusion provided at one of the cable control body and the ratchet gear, and
a recess provided at the other of the cable control body and the ratchet gear, the recess being dimensioned such that the protrusion is movable within the movable range in the first direction and the second direction.

20. The bicycle operating device according to claim 1 , wherein
the biasing member is a spring member configured to bias the ratchet gear relative to the cable control body in the first direction.

21. The bicycle operating device according to claim 1 , wherein
the biasing member is a spring member arranged between the protrusion and the recess so as to bias the ratchet gear relative to the cable control body in the first direction.

22. A bicycle operating device comprising:
a base member;
a cable control body movable relative to the base member in a first direction and a second direction that is different from the first direction, the cable control body including a positioning part;
a positioning pawl configured to directly engage with the positioning part, the positioning pawl movable between a holding position to stop a movement of the cable control body in the first direction, and a non-holding position to allow a movement of the cable control body in the first direction;
a ratchet gear movable relative to the base member, the cable control body, and the positioning part in the first direction and the second direction;
a stopping pawl configured to engage with the ratchet gear, the stopping pawl movable between a stopping position to stop a movement of the ratchet gear in the first direction, and a non-stopping position to allow a movement of the ratchet gear in the first direction, the ratchet gear being coupled to t
