DESCRIPTION OF THE EMBODIMENTS

The embodiment(s) will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the various drawings.

Referring initially to FIG. 1, a bicycle operating device 10 in accordance with an embodiment is configured to be mounted to a bicycle handlebar H. The bicycle operating device 10 is configured to operate a bicycle component BC. Examples of the bicycle component BC includes an electric shift device, an electric seatpost, an electric suspension, and other electric devices. In this embodiment, the bicycle operating device 10 is configured to be mounted to a free end H1 of the bicycle handlebar H such as a time trial handlebar, a bull horn handlebar, or a flat handlebar. Namely, the bicycle operating device 10 is constructed as a bar-end type operating device. However, the bicycle operating device 10 can be mounted to other type of handlebar if needed and/or desired. The bicycle operating device can be mounted to a part other than the bicycle handlebar H. The bicycle operating device 10 can be a right-hand side operating device and a left-hand side operating device.

In the present application, the following directional terms “front,” “rear,” “forward,” “rearward,” “left,” “right,” “transverse,” “upward” and “downward” as well as any other similar directional terms refer to those directions which are determined on the basis of a user (e.g., a rider) who sits on a saddle (not shown) of a bicycle with facing the bicycle handlebar H. Accordingly, these terms, as utilized to describe the bicycle operating device 10, should be interpreted relative to the bicycle equipped with the bicycle operating device 10 as used in an upright riding position on a horizontal surface.

The bicycle operating device 10 comprises a base member 12 and a user interface member 14. The base member 12 is configured to be mounted to the free end H1 of the bicycle handlebar H. The user interface member 14 is provided outside the bicycle handlebar H to receive a user input.

The base member 12 includes a mounting portion 16 configured to be mounted within an interior H2 of the free end H1 of the bicycle handlebar H in a mounting state where the base member 12 is mounted to the free end H1 of the bicycle handlebar H. The base member 12 has a longitudinal direction D1 parallel to a center axis A1 of the free end H1 of the bicycle handlebar H in the mounting state. The base member 12 includes a first base end 12A and a second base end 12B opposite to the first base end 12A along the longitudinal direction D1. The user interface member 14 is located at the first base end 12A. The mounting portion 16 of the base member 12 is located at the second base end 12B. In this embodiment, the base member 12 includes a plurality of parts. The base member 12 can be integrally provided as a one-piece unitary member.

As seen in FIG. 2, the mounting portion 16 includes a base body 18, a rotatable member 22, an adjustment member 24, a first expansion member 26, a second expansion member 28, a third expansion member 30, a fourth expansion member 32, and an elastic ring 34. The rotatable member 22 is rotatably mounted on the base body 18 about a rotational axis A2 extending in the longitudinal direction D1. The adjustment member 24 is movably mounted to the base body 18. The adjustment member 24 is rotatable relative to the base body 18 about the rotational axis A2 and is movable relative to the base body 18 in the longitudinal direction D1.

In this embodiment, the base body 18 includes an attachment part 36 and a coupling support 38. The coupling support 38 extends from the attachment part 36 in the longitudinal direction D1. The base member 12 includes a cover 39. The cover 39 is detachably attached to the base body 18. Specifically, the cover 39 is attached to the attachment part 36. However, the cover 39 can be omitted from the base member 12.

The term “detachably attached” or “detachably attaching,” as used herein, encompasses configurations in which an element directly secured to another element by directly affixing the element to the other element while the element is detachable from the other element without substantial damage; and configurations in which the element is indirectly secured to the other element via intermediate member(s) while the element is detachable from the other element and the intermediate member(s) without substantial damage. This concept also applies to words of similar meaning, for example, “detachably secured,” “detachably joined,” “detachably connected,” “detachably coupled,” “detachably mounted,” “detachably bonded,” “detachably fixed” and their derivatives.

As seen in FIGS. 3 and 4, the coupling support 38 includes an externally threaded part 38A. The adjustment member 24 includes a coupling part 40 and a guide part 42. The coupling part 40 extends from the guide part 42 in the longitudinal direction D1 and includes a coupling threaded hole 40A. The externally threaded part 38A is threadedly engaged with the coupling threaded hole 40A. Rotation of the adjustment member 24 relative to the base body 18 moves the adjustment member 24 relative to the base body 18 in the longitudinal direction D1. The guide part 42 includes a guide surface 42A. The guide surface 42A is inclined relative to the rotational axis A2 and is in slidable contact with the first to fourth expansion members 26 to 32.

The rotatable member 22 includes a tubular body 44 and a flange 46. The flange 46 extends radially outwardly from an axial end of the tubular body 44. The tubular body 44 includes a through-hole 48, an additional guide surface 50, a first guide recess 52, and a second guide recess 54. The through-hole 48 extends along the rotational axis A2. The coupling support 38 extends through the through-hole 48 to rotatably support the rotatable member 22. The additional guide surface 50 is in slidable contact with the first to fourth expansion members 26 to 32.

The adjustment member 24 includes a first slide part 56 and a second slide part 58. The first slide part 56 extends radially outwardly from the coupling part 40 and is movably provided in the first guide recess 52. The second slide part 58 extends radially outwardly from the coupling part 40 and is movably provided in the second guide recess 54. The first slide part 56 is provided on an opposite side of the second slide part 58 with respect to the rotational axis A2.

The adjustment member 24 is coupled to the rotatable member 22 to rotate relative to the base body 18 along with the rotatable member 22. Furthermore, the adjustment member 24 is coupled to the rotatable member 22 to be movable relative to the rotatable member 22 in the longitudinal direction D1. Rotation of the rotatable member 22 relative to the base body 18 rotates the adjustment member 24 relative to the base body 18 about the rotational axis A2, moving the adjustment member 24 relative to the base body 18 and the rotatable member 22 in the longitudinal direction D1.

As seen in FIGS. 3 and 4, the first to fourth expansion members 26 to 32 are radially movable relative to the base body 18. The first to fourth expansion members 26 to 32 are arranged in a circumferential direction D2 (FIG. 2) defined about the rotational axis A2 to define an outer diameter DM. The first to fourth expansion members 26 to 32 are radially supported by the rotatable member 22 and the adjustment member 24.

The elastic ring 34 elastically couples the first to fourth expansion members 26 to 32 to bias the first to fourth expansion members 26 to 32 toward the rotational axis A2. This presses the first to fourth expansion members 26 to 32 against the guide surface 42A and the additional guide surface 50. Examples of the elastic ring 34 include a coil spring.

Rotation of the rotatable member 22 relative to the base body 18 moves the adjustment member 24 relative to the base body 18 in the longitudinal direction D1, moving the first to fourth expansion members 26 to 32 to increase or decrease the outer diameter DM (FIG. 3). The first to fourth expansion members 26 to 32 come into contact with an inner peripheral surface H3 (FIG. 1) of the bicycle handlebar H when the outer diameter DM increase in response to the rotation of the rotatable member 22. Thus, the bicycle operating device 10 is detachably mounted to the bicycle handlebar H.

The first opening 84A can be omitted from the first coupling end 84, and the first coupling end 84 can be coupled to the user interface member 14.

The second coupling end 86 includes a second opening 86A. The input member 70 extends through the second opening 86A. In this embodiment, the input body 72 and the cap 74 extend through the second opening 86A. The cap 74 is provided in the second opening 86A. The cap 74 includes a coupling groove 74A having an annular shape. The second coupling end 86 is fitted in the coupling groove 74A. The second opening 86A can be omitted from the second coupling end 86, and the second coupling end 86 can be coupled to the input member 70.

The biasing part 79 extends between the first coupling end 84 and the second coupling end 86. The biasing part 79 couples the first coupling end 84 to the second coupling end 86. The biasing part 79 is integrally provided with the first coupling end 84 and the second coupling end 86 as a one-piece unitary member. However, the biasing part 79 can be a separate member from at least one of the first coupling end 84 and the second coupling end 86.

In this embodiment, the input body 72 and the cap 74 are made of a non-metallic material such as rubber. The intermediate member 78 is made of a metallic material such as a spring steel. However, the materials of these members are not limited to this embodiment.

As seen in FIG. 4, the transmitting structure 68 (e.g., the input member 70 and the intermediate member 78) positions the user interface member 14 at the first rest position P11 in a state where the user interface member 14 is not operated by the user. The input member 70 moves from the second rest position P21 to the second operated position P22 in the second direction D32 when the user interface member 14 is pivoted from the first rest position P11 to the first operated position P12 by the user.

The intermediate member 78 transmits the first movement M1 (e.g., a pivotal movement) of the user interface member 14 to the input member 70. The input body 72 is moved from the second rest position P21 to the second operated position P22 in the second direction D32 in response to the first movement M1 of the user interface member 14. The elastic part 76 keeps the center axis A4 of the input body 72 relative to the electrical switch SW parallel to the second direction D32 when the input body 72 is moved from the second rest position P21 to the second operated position P22 in the second direction D32. The intermediate member 78 (e.g., the biasing part 79) is elastically deformed to absorb a difference between the first movement M1 of the user interface member 14 and the second movement M2 of the input member 70 when the user interface member 14 is moved from the first rest position P11 to the first operated position P12. The user interface member 14 returns from the first operated position P12 to the first rest position P11 because of the biasing force generated by at least one of the input member 70 and the intermediate member 78.

As seen in FIGS. 4 and 8, the bicycle operating device 10 further comprises a wireless communicator WC electrically connected to the electrical switch SW to wirelessly transmit a signal to the bicycle component BC (FIG. 1) in response to an operation of the electrical switch SW. The wireless communicator WC is mounted to the base member 12. At least one of the electrical switch SW and the wireless communicator WC is provided in the interior space 66A of the housing 66. The wireless communicator WC is mounted to the base member 12 outside the bicycle handlebar H in a mounting state where the base member 12 is mounted to the free end H1 of the bicycle handlebar H. The housing 66 is made of non-metallic material such as resin material to transmit the signal. The base body 18 is made of non-metallic material such as resin material to transmit the signal. The cover 39 is made of non-metallic material such as resin material to transmit the signal. The user interface member 14 is made of non-metallic material such as resin material to transmit the signal. In this embodiment, the electrical switch SW and the wireless communicator WC are provided in the interior space 66A. However, the positions of the electrical switch SW and the wireless communicator WC are not limited to this embodiment. In this embodiment, the bicycle operating device 10 is configured to wirelessly operate the bicycle component BC. However, the bicycle operating device 10 can be configured to operate the bicycle component BC using a control cable. In such an embodiment, the wireless communicator WC can be omitted from the bicycle operating device 10.

The bicycle operating device 10 comprises a circuit board 94. In this embodiment, the electrical switch SW and the wireless communicator WC are electrically mounted on the circuit board 94. The circuit board 94 is secured to the housing 66 and is provided in the interior space 66A.

As seen in FIG. 8, the wireless communicator WC is electrically connected to the electrical switch SW with a bus 96. The wireless communicator WC includes a processor WC1, a memory WC2, a signal generating circuit WC3, a signal transmitting circuit WC4, a signal receiving circuit WC5, and an antenna WC6. Thus, the wireless communicator WC can also be referred to as a wireless communication circuit or circuitry WC in the present application. The processor WC1 includes a central processing unit (CPU) and a memory controller. The memory WC2 is electrically connected to the processor WC1. The memory WC2 includes a read only memory (ROM) and a random-access memory (RAM). The ROM includes a non-transitory computer-readable storage medium. The RAM includes a transitory computer-readable storage medium. The memory WC2 includes storage areas each having an address in the ROM and the RAM. The processor WC1 controls the memory WC2 to store data in the storage areas of the memory WC2 and reads data from the storage areas of the memory WC2. The memory WC2 (e.g., the ROM) stores a program. The program is read into the processor WC1, and thereby performing functions of the wireless communicator WC (e.g., at least part of functions of the signal generating circuit WC3, the signal transmitting circuit WC4, and the signal receiving circuit WC5).

The signal generating circuit WC3 generates wireless signals based on the input operation received by the electrical switch SW. The signal generating circuit WC3 superimposes digital signals on carrier wave using a predetermined wireless communication protocol to generate the wireless signals. The signal transmitting circuit WC4 transmits the wireless signal via the antenna WC6 in response to the input operation received by the electrical switch SW. In this embodiment, the signal generating circuit WC3 can encrypt control information (e.g., shift control command, seatpost control command, suspension control command, or other control commands) to generate encrypted wireless signals. The signal generating circuit WC3 encrypts digital signals stored in the memory WC2 using a cryptographic key. The signal transmitting circuit WC4 transmits the encrypted wireless signals. Thus, the wireless communicator WC wirelessly transmits the wireless signal to upshift or downshift the additional component BC2 when the electrical switch SW is closed to be activated by the input operation.

Further, the signal receiving circuit WC5 receives a wireless signal from the additional component BC2 via the antenna WC6. In this embodiment, the signal receiving circuit WC5 decodes the wireless signal to recognize information wirelessly transmitted from the additional component BC2. The signal receiving circuit WC5 may decrypt the encrypted wireless signal using the cryptographic key. Namely, the wireless communicator WC is configured to transmit a wireless signal to control the bicycle component BC and to receive a wireless signal to recognize information from the bicycle component BC. In other words, the wireless communicator WC is provided as a wireless transmitter and a wireless receiver. In this embodiment, the wireless communicator WC is integrally provided as a single module or unit. However, the wireless communicator WC can include a wireless transmitter and a wireless receiver which are provided as separate modules or units arranged at different positions from each other. The signal receiving circuit WC5 can be omitted from the wireless communicator WC.

The power supply PS is electrically connected to the wireless communicator WC to supply electricity to the wireless communicator WC via the bus 96.

The power supply PS is electrically connected to the electricity generator EG to accumulate electricity generated by the electricity generator EG. The power supply PS includes a capacitor PS1, a rectifying circuit PS2, and a voltage regulator PS3. The capacitor PS1, the rectifying circuit PS2, and the voltage regulator PS3 are electrically connected to the electricity generator EG to rectify the electric energy generated by the electricity generator EG. The rectifying circuit PS2 is electrically connected to the circuit board 94 (the bus 96). The capacitor PS1 is electrically connected to the electricity generator EG to accumulate electricity generated by the electricity generator EG. The voltage regulator PS3 regulates the power source voltage to a level at which various circuits of the wireless communicator WC can properly operate. The regulated power source voltage is applied from the power supply PS to the wireless communicator WC. The electricity generator EG, the capacitor PS1, and the rectifying circuit PS2 can be omitted from the power supply PS when the power supply PS includes a battery or another power supply source.

As seen in FIG. 4, the power supply PS is provided in the housing 66. The capacitor PS1 and the rectifying circuit PS2 are provided in the interior space 66A of the housing 66. However, the power supply PS can be provided at other positions.

In this embodiment, as seen in FIG. 5, the housing 66 constitutes a single module including the input body 72, the electrical switch SW, the wireless communicator WC, the electricity generator EG, the power supply PS, and the circuit board 94. However, these elements can be at least partly provided as separate modules from each other. As seen in FIGS. 4 and 5, the single module further includes an additional input member 98 mounted to the housing 66. The additional input member 98 has substantially the same as the input member 70 except for the cap 74. The additional input member 98 can be utilized as the input member 70. Thus, it will not be described in detail here for the sake of brevity.

The assembling procedure of the bicycle operating device 10 will be described below referring to FIG. 5. As seen in FIG. 5, for example, the housing 66 is attached to the base body 18 with a fastener such as a screw or an adhesive agent when the bicycle operating device 10 is assembled.
