Abstract

A control device for a bicycle is arranged or can be arranged on the handlebar of the bicycle and serves to wirelessly drive at least one electronic, electrical, electromechanical or electrohydraulic component of the bicycle. The control device includes an operator control arrangement which has at least one manually operable operator control element and is designed to respond to operation of the operator control element and to output electrical signals which represent the operation. The control device also includes at least one electronic circuit arrangement comprising a radio communication circuit and a control circuit which is connected or can be connected to the operator control arrangement. The control device also may include at least one antenna which is connected or can be connected to the radio communication circuit or which is integrated into the said communication circuit.

First claim

The invention claimed is:

1. A control device for a bicycle, the control device comprising:
an operator control arrangement which has at least one manually operable operator control element and is designed to respond to a rotational operation of the operator control element about a rotational axis in a first direction and a second direction and to output electrical signals which represent the operations;
at least one electronic circuit arrangement comprising a radio communication circuit, a control circuit connected to the operator control arrangement, a battery configured to provide power to the radio communication circuit and the control circuit, and at least one antenna which is connected or can be connected to the radio communication circuit or which is integrated into the said communication circuit, the radio communication circuit designed to transmit wireless control commands to at least one electronic, electrical, electromechanical or electrohydraulic component of the bicycle;
a housing which is held on the outside of the handlebar and which contains the electronic circuit arrangement, the at least one control element of the operator control arrangement rotatably mounted on the housing; and
a fastening apparatus configured to affix the housing on a handlebar about a handlebar axis,
wherein the rotation axis is offset from the handlebar axis.

2. The control device according to claim 1 , wherein the electronic circuit arrangement has a printed circuit board arrangement, and the antenna is supported by the printed circuit board arrangement.

3. The control device according to claim 2 , wherein the printed circuit board arrangement is contained within an interior of the housing.

4. The control device according to claim 3 , wherein the housing includes a battery compartment and a battery compartment cover, and the battery is a replaceable battery.

5. The control device according to claim 4 , wherein wherein the housing further includes retainers for at least one electrical contact switch, the at least one electrical contact switch configured to be operated by the operator control element when the operator control element is rotated in the first direction or the second direction.

6. The control device according to claim 5 , wherein the operator control element includes a first contact surface configured to rotate the operator control element in the first direction when pressure is applied and a second contact surface configured to rotate the operator control element in the second direction when pressure is applied.

7. The control device according to claim 1 , wherein the operator control element is releasably mounted on the housing.

8. The control device according to claim 7 , wherein the first contact surface is disposed on a first projection and the second contact surface is disposed on a second projection.

9. The control device according to claim 1 , wherein the at least one electrical contact switch is a snap-action switch.

10. The control device according to claim 9 , wherein the antenna is configured so as to be oriented at a skewed angle to the handlebar axis.
