Abstract
A bicycle generator or a shifting device has a base member, a rotation receiving member and a dynamo. The base member is configured to be mounted only in vicinity of a hub axle. The rotation receiving member is rotatably mounted on the base member and is rotated by a rotational part of a bicycle. The dynamo is coupled to the rotation receiving member to generate electrical energy in response to rotation of the rotation receiving member. In the case of the shifting device, a shifting unit is provided that includes an electric motor and an output member that engages a part of a bicycle hub transmission device.
Claims28
A bicycle generator comprising:
- a base member configured to be non-rotatably mounted on a fixed hub axle;
- a rotation receiving member rotatably mounted on the base member and configured to be rotated by a rotational part of a bicycle;
- a dynamo supported on the base member and operatively coupled to the rotation receiving member such that the dynamo generates electrical energy in response to rotation of the rotation receiving member;
- an electrical storage unit disposed on the base member and electrically coupled to the dynamo to store electrical energy generated by the dynamo;
- and
- a rectify device supported on the base member and that rectifies current from the dynamo.
A bicycle hub transmission shifting device comprising:
- a base member having a hub mounting portion non-rotatably mounted on a fixed hub axle;
- a shifting unit supported on the base member and including an electric motor and an output member arranged to engage a part of a bicycle hub transmission;
- a rotation receiving member rotatably mounted on the base member and configured to be rotated by a rotational part of a bicycle;
- a dynamo supported on the base member and operatively coupled to the rotation receiving member such that the dynamo generates electrical energy in response to the rotation receiving member and provides electrical energy to the shift unit;
- and
- an electrical storage unit disposed on the base member, the electrical storage unit being electrically coupled to the dynamo to store electrical energy generated by the dynamo and being electrically coupled to the electric motor to supply electrical energy from the electrical storage unit.
