For example, the operating device12is configured to wirelessly control the lamp20and the rear derailleur26, while the operating device12can be configured to wirelessly control the adjustable front derailleur18and the lamp20. Of course, it will be apparent from this disclosure that the bicycle components controlled by the operating device12and the operating device12′ is not limited to this particular configuration. Also, the operating device12and the operating device12′ also function as brake control devices in a conventional manner.

Here, the operating device12is mounted on the right side of the handlebar H, while the operating device12′ is mounted on the left side of the handlebar H.

The operating member68and the operating member70are movably mounted to the operating lever64, while the electrical switch68aand the electrical switch70aare fixed to the operating lever64. Thus, here, pivotal movement of the operating member68relative to the operating lever64causes the operating member68to activate (depress) the electrical switch68ato operate an external device. Similarly, pivotal movement of the operating member70relative to the operating lever64causes the operating member70to activate (depress) the electrical switch70ato operate an external device.

In the case of the operating device12′, which has the same physical structure as the operating device12, the electrical switch68aand the electrical switch70aare used to control the adjustable front derailleur18(BC). In other words, in the case of the operating device12′, one of the electrical switch68aand the electrical switch70aoutputs an upshift signal to the adjustable front derailleur18, while the other one of the electrical switch68aand the electrical switch70aoutputs a downshift signal to the adjustable front derailleur18. The upshift signal and the downshift signal are wireless communicated from the wireless communicator36(seeFIG.3) of the power receiver40to the wireless communicator36of the adjustable front derailleur18.

In the case where the controller38of the rear derailleur26determines a parameter (e.g., temperature) of the rechargeable power source32of the rear derailleur26is outside of the permissible range, then the controller38of the rear derailleur26can restrict the operating function of the electric motor or actuator126a(the electrical part30) of the electric motor unit126(the electrical part30) so that the rear derailleur26can only downshift, only upshift, or move to a predetermined shift setting.

Referring now toFIGS.1to3and10, the object holder21provided to each of the first bicycle B1and the second bicycle B2will be discussed in more detail. Here, the object holder21is configured to hold a bicycle water bottle WB. However, the object holder21is not limited to a bicycle water bottle. Rather, the object holder21can be other types of holders such as an air pump holder. The bicycle component BC (e.g., the object holder21) basically comprises a base member130and a power receiver131. The power receiver131has the same construction the power receiver40as seen inFIG.3, except that the power receiver131has been adapted to be part of the object holder21.

The base member130is configured to be mounted to a bicycle (e.g., the first bicycle B1or the second bicycle B2). In particular, the base member130includes at least one mounting portion132that is mounted to a braze-on mount of the first bicycle B1or the second bicycle B2using at least one fastener. Here, the base member130includes a pair of mounting portions132that are mounted to a pair of braze-on mounts of the first bicycle B1or the second bicycle B2using a pair of fasteners. The base member130includes a holding portion134that is configured to removably hold at least one object. Here, the holding portion134is configured to hold the water bottle WB such as a reusable water bottle or a disposable water bottle. The holding portion134can also be called a holding portion, a cage, a receptacle, or a clip depending on the structure of the holding portion134. Thus, the object holder21includes a water bottle cage in the illustrated embodiment.

As seen inFIG.10, the power receiver131is mounted to the base member132. In particular, the base member132includes a support portion136configured to support the power receiver131. Basically, as seen inFIG.3, the power receiver141includes the non-contact charging portion141athat is configured to wirelessly receive external electric power and to supply the external electric power to at least one of a rechargeable power source and an electrical component. Also, the power receiver141includes a wireless communicator142and a controller144similar to the other bicycle components BC that are discussed above. The power receiver141has a circuit board PCB in which the wireless communicator142and the controller144are provided on. In this embodiment, the object holder21includes an electrical part146and a rechargeable power source148. Preferably, the circuit board PCB is provided with an AC/DC converter such as the AC/DC converter42shown inFIG.3and discussed above. Preferably, the circuit board PCB is provided with a sensor such as the sensor converter44shown inFIG.3and discussed above. Thus, the circuitry of the circuit board PCB for controlling the electrical part146(the electrical part30) and the rechargeable power source148is the same as circuitry ofFIG.3as discussed above with respect to the other bicycle components BC. Here, in the object holder21, the electrical part146can be, for example, an indicator light, a decorative light, a water bottle heating element, etc. As seen inFIG.10, the electrical part146is a light emitting element for indicating a function of the object holder21such as a level of charge. The rechargeable power source148can be electrically connected to another one of the bicycle components BC via an electrical cord EC1. In this way, the external electric power can be provided to another one of the bicycle components BC via the rechargeable power source148.

In the case where the controller144of the object holder21determines a parameter (e.g., temperature) of the rechargeable power source148is outside of the permissible range, then the controller148of the object holder21can restrict the operating function the electrical part146. For example, if the electrical part30of the object holder21is a light emitting element, then the controller144can turn off or dims the output of the light emitting element.

However, the rechargeable power source148can be remotely located from the power receiver141as needed and/or desired. The housing150is preferably a waterproof structure. Thus, the power receiver141includes a waterproof structure accommodating the non-contact charging portion. Here, the housing150is a two piece structure in which the two parts are screwed together with a rubber seal disposed between the two parts. In this way, the housing150can be open and reclosed to replace the rechargeable power source148or to service the parts of the power receiver141. Alternatively, the housing150can a one-piece member or two parts that are permanently coupled together.

Referring now toFIG.11, the rechargeable power sources32of the bicycle components BC (12,12′,14,16,18,20,21,26) are automatically recharged by one of the non-contact charging devices CD (22,24) while the first bicycle B1or the second bicycle B2is travelling. Thus, in accordance with this disclosure, a non-contact charging method is provided for charging the rechargeable power source of a bicycle component. In particular, one exemplary non-contact charging method or process for recharging the rechargeable power source32for each of the bicycle components BC (12,12′,14,16,18,20,21,26) will now be described with reference toFIG.11. The exemplary non-contact charging method or process ofFIG.11is executed by the controller38at a predetermined time interval and/or each time the electrical part30is operated. Once the predetermined time interval has elapsed and/or each time the electrical part30is operated, the controller38starts the non-contact charging process by communicating with the bicycle component BC and the non-contact charging device CD. Thus, the non-contact charging method comprises starting wireless communication between the bicycle component BC and the non-contact charging device CD. This wireless communication is a form of speech to express any information of the bicycle component BC to indicate a need for the BC to be automatically charged, or the bicycle component BC being placed near the non-contact charging device CD when a user decide to charge the bicycle component BC. Once wireless communication exists between the bicycle component BC and the non-contact charging device CD, the contact charging method proceeds to step S1in the flowchart ofFIG.11.

In step S1, the controller38detects a condition of the rechargeable power source32. In other words, the non-contact charging method comprises detecting a condition of the rechargeable power source32. The condition of the rechargeable power source32can be detected in a variety of ways. In any case, the detected condition of the rechargeable power source32is indicative of a condition of the rechargeable power source32relating to at least one of a state of charge, a charge current, an internal resistance, a temperature, a voltage, a power source age, an electrical load, and any other parameter relating to chargeability. In the illustrated embodiment, the temperature of the rechargeable power source32is used as the condition the rechargeable power source32that is being detected. Thus, the non-contact charging method further comprises detecting a temperature of the rechargeable power source32as the condition. After detecting the condition (e.g., the temperature and/or the voltage) of the rechargeable power source32, the controller38proceeds to step S2.

In step S2, the controller38confirms a parameter (e.g., the temperature and/or the voltage) of the rechargeable power source32based on a result of the condition that was detected. In other words, the non-contact charging method comprises confirming a parameter of the rechargeable power source32based on a result of the condition that was detected. In particular, the controller38determines whether the detected condition or parameter of the rechargeable power source32is inside a permissible range. For example, the controller38can have prestored in memory charging tables and/or charging maps charging that control the charging based on one or more of a plurality of parameters such as a state of charge, a charge current, an internal resistance, a temperature, a voltage, a power source age, an electrical load, and any other parameter relating to chargeability.

Preferably, the parameter is an electrical load or an electrical condition such as the remaining current power of the rechargeable power source32, the temperature/heat of the rechargeable power source32or the electrical device30. The parameter (the electrical load or the electrical condition) is being detected by using one or more sensors, and the information detected by the sensor(s) will be process by the controller38to check whether the (the electrical load or the electrical condition) is below or above the permissible range. For example, the electrical load of the rechargeable power source32can be determined from the temperature detected by the temperature sensor44A and the electrical condition (remaining electric power) of the rechargeable power source32can be determined from the voltage detected by the of the rechargeable power source32can be determined from the temperature detected by the temperature sensor44A sensor44B. If the temperature and/or remaining power is below the permissible range, the controller38will control the non-contact charging portion34to maintain the current charging level and/or phase. If the temperature and/or the remaining power is above the permissible range, the controller38will control the non-contact charging portion34to adjust the charging level, for example to lower voltage and/or longer charging time.

Upon determining the parameter is indicative that the state of charge of the rechargeable power source32is suitable for operating the bicycle component BC without any restrictions (i.e., normal operation of the bicycle component BC is permissible), the controller38proceeds to step S3.

In step S3, the controller38permits control of the bicycle component BC so that the bicycle component BC can be operated without any restrictions (i.e., normal operation of the bicycle component BC is permissible). In other words, the non-contact charging method further comprises maintaining the operating function of the bicycle component BC upon determining the parameter of the rechargeable power source32is inside of the permissible range. Then, the controller38proceeds to step S4.

In step S4, the controller38starts or maintains a predetermined charging mode that is suitable for the detected condition of the rechargeable power source32. In other words, the non-contact charging method comprises charging the rechargeable power source32of the bicycle component BC. Here, the predetermined charging mode can be a preferred charging mode such as a constant current mode of charging. The preferred charging mode is used since the detected condition of the rechargeable power source32is indicative of a condition in which the bicycle component BC can be operated without restrictions and the rechargeable power source32can be recharged optimally. Also, in the illustrated embodiment, as mentioned above, the non-contact charging portion34outputs outputted. Thus, in the illustrated embodiment, the AC/DC converter42is provided between the non-contact charging portion34and the rechargeable power source32to convert the alternating current outputted by the non-contact charging portion34to direct current that is received by the rechargeable power source32. As a result, in the illustrated embodiment, the non-contact charging method further comprises converting alternating current from the non-contact charging portion34to direct current that is supplied to the rechargeable power source32. Then, the controller38proceeds to step S5.

In step S5, the controller38monitors the voltage of the rechargeable power source32using the voltage sensor44B, which either directly detects the voltage of the rechargeable power source32or indirectly detects the voltage of the rechargeable power source32by detecting the voltage of the electrical part30. Thus, the non-contact charging method further comprises monitoring the voltage of the rechargeable power source32after a prescribed period of time elapsing from a start of the charging. Then, the controller38proceeds to step S6.

In step S6, the controller38determines whether the rechargeable power source32is fully charged (i.e., charged to a prescribed level in which charging is to be stopped). As used herein, the term “fully charged” does not require the rechargeable power source32to be charged to its maximum capacity. Rather, the term “fully charged” can include a charge capacity that is less than the maximum capacity. If the controller38determines the rechargeable power source32has reached the desired fully charge capacity, then the non-contact charging method ends until the next time interval or the bicycle component BC is operated. On the other hand, if the controller38determines the rechargeable power source32has not reached the desired fully charge capacity, then the non-contact charging method returns to step S1to detect the condition of the rechargeable power source32and proceed to step S2.

In step S2, if the controller38determines a parameter based on the detected condition of the rechargeable power source32is outside the permissible range, then, the controller38proceeds to step S7.

In step S7, the controller38restricts control of the bicycle component BC so that the bicycle component BC cannot be operated, or can be operated only with certain functionality or reduced performance. In other words, the non-contact charging method further comprises restricting an operating function of the bicycle component BC upon determining a parameter of the rechargeable power source32is outside of a permissible range. Then, the controller38proceeds to step S8.

In step S8, the controller38is configured to carry out countermeasures to reduce the temperature of the rechargeable power source32. In other words, the non-contact charging method further comprises applying thermal management to lower the temperature of the rechargeable power source32. For example, the rechargeable power source32can be cooled using heat pipes, fans, etc. Of course, it will be apparent from this disclosure that step S8can be omitted or skipped as needed an/or desired. Then, the controller38proceeds to step S9.

In step S9, the controller38adjusts a voltage of the rechargeable power source32to change the charging mode from the preferred charging mode (e.g., a constant current mode) to a charging mode (e.g., a low voltage mode) that is more suitable for the detected condition of the rechargeable power source32. In the case where a low voltage mode is used for charging the rechargeable power source32, a voltage supplied to the rechargeable power source32is lowered relative to the voltage supplied to the rechargeable power source32upon determining the parameter of the rechargeable power source32is inside of the permissible range. In other words, the non-contact charging method further comprises adjusting a voltage of the rechargeable power source32upon determining the parameter of the rechargeable power source32is outside of the permissible range. Then, the controller38proceeds to step S6where the controller38determines whether the rechargeable power source32is fully charged as discussed below.

Referring now toFIG.12, when the controller38of the bicycle component BC (12,12′,14,16,18,20,21,26) determines that the first bicycle B1or the second bicycle B2is stopped or when the bicycle component BC is not installed on the bicycle B, it is not necessary to restrict an operating function of the bicycle component BC (12,12′,14,16,18,20,21,26). Thus, in cases where the first bicycle B1and the second bicycle B2is stopped or when the bicycle component BC is not installed on the first bicycle B1and the second bicycle B2, the non-contact charging method ofFIG.12is performed for recharging the rechargeable power source32for each of the bicycle components BC (12,12′,14,16,18,20,21,26).

Basically, the non-contact charging method ofFIG.12is identical to the non-contact charging method ofFIG.11, except that steps S7and S3of the non-contact charging method ofFIG.11have been omitted from the non-contact charging method ofFIG.12. Thus, steps S1, S2, and S4to S9of the non-contact charging method ofFIG.12are the same as steps S1, S2, and S4to S9of the non-contact charging method ofFIG.11. For the sake of brevity, the descriptions of steps S1, S2, and S4to S9will not be repeated for the non-contact charging method ofFIG.12.

Referring now toFIG.13, optionally, the controller38of each or some of the bicycle components BC (12,12′,14,16,18,20,21,26) can be configured carry out a process to start recharging the rechargeable power source32upon determining the rechargeable power source32has fallen below a prescribed charge level. The process ofFIG.13is executed by the controller38at a predetermined time interval and/or each time the electrical part30is operated.

Here, in step S10, the controller38detects the voltage of the rechargeable power source32using the voltage sensor44B, which either directly detects the voltage of the rechargeable power source32or indirectly detects the voltage of the rechargeable power source32by detecting the voltage of the electrical part30. Then, the controller38proceeds to step S11.

In step S11, the controller38determines whether the charge level of the rechargeable power source has fallen below a threshold value. The threshold valve can be the same for each or some of the bicycle components BC (12,12′,14,16,18,20,21,26). Alternatively, the threshold valves can be different for each or some of the bicycle components BC (12,12′,14,16,18,20,21,26). If the controller38determines the charge level of the rechargeable power source has fallen below a threshold value, then the controller38proceeds to step S12. On the other hand, if the controller38determines the charge level of the rechargeable power source has fallen above a threshold value, then process ends until the next time interval or the bicycle component BC is operated.

In step S12, the controller38instructs the wireless communicator36to broadcast information relating to the condition of the rechargeable power source32. The information relating to the condition of the rechargeable power source32is received by the wireless communicator52of one or both of the non-contact charging devices CD (22,24). In this way, the controller54of the power transmitter60can control the wireless transfer of electric power from the power source48via the non-contact charging coil50ato the non-contact charging coil34aof the power receiver40of the bicycle component BC (12,12′,14,16,18,20,21,26).

Referring now toFIGS.14and15, a non-contact charging system210is illustrated. The non-contact charging system210basically comprises a bicycle component BC and a non-contact charging device CD. In this embodiment, the wireless communicators have been omitted from the non-contact charging system210. However, the wireless communicators of the non-contact charging system10can be included in the non-contact charging system210if needed and/or desired.

The bicycle component BC (e.g., an object holder212) basically comprises a base member214and a power receiver216. The power receiver216is configured to receive electric power from the non-contact charging device CD. Here, the power receiver216includes an electrical cord EC1that is configured to supply the external electric power to the at least one of a rechargeable power source and an electrical component. In this way, the power receiver216can recharge at least one rechargeable power source or supply electric power to at least one electrical component such as one of the bicycle components (12,12′,14,16,18,20,26). The rechargeable power source can be either provided to the power receiver216or provided to one of the bicycle components BC (12,12′,14,16,18,20,26) of the first bicycle B1or the second bicycle B2.

Basically, the non-contact charging device CD can be electrically connected to a power source such the electric power network of a home or a building by an electrical cord EC2. The external electric power received from the electric power network of the home or the building can then be wirelessly transmitted from the non-contact charging device CD to the object holder212.

Here, the holding portion220is configured to hold a water bottle such as a reusable water bottle or a disposable water bottle. In particular, the holding portion220supports a side portion of the object or water bottle. The holding portion220can also be called a holding portion, a cage, a receptacle, or a clip depending on the structure of the holding portion220. Thus, the object holder212include a water bottle cage in the illustrated embodiment. Also, the holding portion220is configured to support the non-contact charging device CD. In this way, the non-contact charging device CD is supported by the object holder212during electric power transfer.

The power receiver216is mounted to the base member214. In particular, the base member132includes a support portion222configured to support the power receiver216. Here, the support portion222is located at the bottom of the holding portion220such that a bottom of a water bottle can rest on the support portion222. The support portion222also supports the non-contact charging device CD when the non-contact charging device CD is disposed in the holding portion220. Alternatively, the support portion222can be integrated into the power receiver216such that the non-contact charging device CD rest directly onto the power receiver216.

However, the location of the power receiver216is not limited to being located at the support portion222.

The AC/DC converter232converts the alternating current outputted by the non-contact charging portion224to direct current that is received by the rechargeable power source228. In this way, the direct current outputted by the AC/DC converter232is used to recharge the rechargeable power source228.

The bicycle component BC that receives the electric power from the rechargeable power source228preferably has a controller, an electrical part and a sensor that are electrically connected to the rechargeable power source228. The sensor is configured to detect information relating to a condition of the rechargeable power source228. The sensor is configured to communicate with the controller230of the power receiver216. The sensor234can be configured to communicate with the controller of the bicycle component BC which communicates with the controller226of the power receiver216. By employing the sensor, the recharging of the rechargeable power source228can be improved based on the condition of the rechargeable power source228.

The bicycle component BC that receives the electric power from the rechargeable power source228also includes an electrical part that receives electric power from the rechargeable power source228. The electrical part can be a variety of electrical parts, such as an electric motor, an electrical switch, a light emitting diode, or an electric actuator, depending on the bicycle component BC.
