Abstract

A bicycle operating device comprises a base member, an operating member, a hydraulic unit, an electrical switch, a wireless communicator, and a power supply. The base member includes a first end to be mounted to a bicycle handlebar and a second end opposite to the first end. The operating member is pivotally coupled to the base member about a first pivot axis. The wireless communicator is electrically connected to the electrical switch to wirelessly transmit a signal to an additional component in response to an input operation. The power supply is electrically connected to the wireless communicator to supply electrical power to the wireless communicator. The hydraulic unit at least partly overlaps with at least one of the wireless communicator and the power supply when viewed from a first direction parallel to the first pivot axis.

First claim

What is claimed is:

1. A bicycle operating device comprising:
a base member including
a first end to be mounted to a bicycle handlebar, and
a second end opposite to the first end;

an operating member pivotally coupled to the base member about a first pivot axis;
a hydraulic unit coupled to the operating member to operate a bicycle component in response to an operation of the operating member;
an electrical switch to be activated by an input operation from a user;
a wireless communicator electrically connected to the electrical switch to wirelessly transmit a signal to an additional component in response to the input operation; and
a power supply electrically connected to the wireless communicator to supply electrical power to the wireless communicator, the hydraulic unit at least partly overlapping with at least one of the wireless communicator and the power supply when viewed from a first direction parallel to the first pivot axis.

2. The bicycle operating device according to claim 1 , wherein
the hydraulic unit is at least partly disposed closer to the first end than the first pivot axis when viewed from the first direction.

3. The bicycle operating device according to claim 2 , wherein
the bicycle operating device is configured to be mounted on a bicycle having a transverse center plane,
the base member includes a first lateral surface and a second lateral surface, the first lateral surface being disposed closer to the transverse center plane than the second lateral surface,
the at least one of the wireless communicator and the power supply is disposed between the first lateral surface and the second lateral surface in the first direction, and
the at least one of the wireless communicator and the power supply is at least partly disposed closer to the first lateral surface than the hydraulic unit in the first direction.

4. The bicycle operating device according to claim 3 , wherein
the wireless communicator is at least partly disposed closer to the first lateral surface than the hydraulic unit in the first direction.

5. The bicycle operating device according to claim 3 , wherein
the at least one of the wireless communicator and the power supply is entirely disposed closer to the first lateral surface than the hydraulic unit in the first direction.

6. The bicycle operating device according to claim 5 , wherein
the wireless communicator is entirely disposed closer to the first lateral surface than the hydraulic unit in the first direction.

7. The bicycle operating device according to claim 2 , wherein
the base member includes a mounting surface disposed at the first end, the mounting surface having a curved shape corresponding to a drop-down handlebar.

8. The bicycle operating device according to claim 2 , wherein
the base member includes a grip portion arranged between the first end and the second end.

9. The bicycle operating device according to claim 2 , wherein
the base member includes a pommel portion disposed at the second end.

10. The bicycle operating device according to claim 1 , wherein
the hydraulic unit is at least partly disposed closer to the second end than the first pivot axis when viewed from the first direction.

11. The bicycle operating device according to claim 10 , wherein
the base member includes a mounting surface at the first end, the mounting surface having a curved shape corresponding to a drop-down handlebar.

12. The bicycle operating device according to claim 10 , wherein
the base member includes a grip portion arranged between the first end and the second end.

13. The bicycle operating device according to claim 10 , wherein
the base member includes a pommel portion disposed at the second end.

14. The bicycle operating device according to claim 13 , wherein
the electrical switch is disposed at the pommel portion.

15. The bicycle operating device according to claim 1 , wherein
the hydraulic unit comprises
a cylinder bore, and
a piston movably provided in the cylinder bore, and

at least one of the cylinder bore and the piston at least partly overlaps with at least one of the wireless communicator and the power supply when viewed from the first direction.

16. The bicycle operating device according to claim 1 , wherein
the hydraulic unit comprises
a cylinder bore,
a piston movably provided in the cylinder bore, and
a hydraulic reservoir connected to the cylinder bore, and

at least one of the cylinder bore, the piston, and the hydraulic reservoir at least partly overlaps with at least one of the wireless communicator and the power supply when viewed from the first direction.

17. The bicycle operating device according to claim 1 , wherein
the wireless communicator is disposed at the operating member, and
the hydraulic unit at least partly overlaps with the power supply when viewed from the first direction.

18. The bicycle operating device according to claim 1 , further comprising:
an additional operating member movably mounted relative to the base member, wherein
the wireless communicator is disposed at the additional operating member, and
the hydraulic unit at least partly overlaps with the power supply when viewed from the first direction.

19. The bicycle operating device according to claim 18 , wherein
the additional operating member is movably coupled to the operating member.
