DETAILED DESCRIPTION OF EMBODIMENTS
Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalent
Referring initially to FIGS. 1 to 3, a bicycle operating device 10 is illustrated in accordance with one illustrative embodiment. The bicycle operating device 10 is mounted on a bicycle handlebar 12 having a handlebar axis A as seen in FIG. 1. As seen in FIG. 2, the bicycle operating device 10 is a part of a bicycle control apparatus, which for example in the illustrated embodiment changes a gear ratio of a bicycle drive train and adjusts a setting of a bicycle suspension as discussed below. The bicycle operating device 10 basically comprises a base member 14, a first operating member 16 and an electrical switch 17. In the illustrated embodiment, as seen in FIG. 3, the bicycle operating device 10 further comprises a second operating member 18 and a clicking mechanism 20 that notifies a rider of when the first and second operating members 16 and 18 have been moved to operate a bicycle component as discussed below. The first operating member 16 is movably supported on the base member 14 from a rest position to an operated position. The second operating member 18 is also movably supported on the base member 14 from a rest position to an operated position.
Also in the illustrated embodiment, the bicycle operating device 10 further comprises an electric control unit 22 that is operated by movement of each of the first and second operating members 16 and 18. Since the bicycle operating device 10 is provided with the electric control unit 22, the bicycle operating device 10 constitutes an electric bicycle operating device. As will become apparent to those skilled in the art from this disclosure, certain aspects of the bicycle operating device 10, which are disclosed herein, can be used in a non-electric bicycle operated operating device that pulls and releases a cable in response to operation of the first and second operating members 16 and 18.
As seen in FIG. 2, the electric control unit 22 includes a controller 24, a first sensor 26, a second sensor 28 and a third sensor 30. Preferably, for example, the controller 24 and the first, second and third sensors 26, 28 and 30 are integrated together on a printed circuit board PC that is mounted to the base member 14. Basically, the first sensor 26 detects operation of the first operating member 16, and outputs signals to the controller 24 based on the movement of the first operating member 16. The second sensor 28 detects operation of the second operating member 18, and outputs signals to the controller 24 based on the movement of the second operating member 18. The third sensor 30 detects operation of the electrical switch 17, and outputs signals to the controller 24 based on the depression of the electrical switch 17. The electric control unit 22 further includes conventional components such as an input interface circuit, an output interface circuit, and storage devices such as a ROM (Read Only Memory) device and a RAM (Random Access Memory) device as needed and/or desired. It will be apparent to those skilled in the art from this disclosure that the precise structure and algorithms for the electric control unit 22 can be any combination of hardware and software that will carry out the functions of the present invention.
In the illustrated embodiment, the first, second and third sensors 26, 28 and 30 wirelessly detect the operation of the first and second operating members 16 and 18 and the electrical switch 17. However, other types of sensing arrangements can be utilized as needed and/or desired. For example, the first, second and third sensors 26, 28 and 30 could be electrically connected to the first and second operating members 16 and 18 and the electric switch 17, respectively, by using contacts and brushes and/or using wires in a conventional manner.
The simplified schematic block diagram of FIG. 2 illustrates one example of the bicycle control apparatus that includes the bicycle operating device 10. The bicycle control apparatus includes a main microcomputer 32 that is mounted on a portion of a bicycle in a conventional manner. The main microcomputer 32 further includes a central processing unit (CPU) and conventional components such as an input interface circuit, an output interface circuit, and storage devices such as a ROM (Read Only Memory) device and a RAM (Random Access Memory) device as needed and/or desired. It will be apparent to those skilled in the art from this disclosure that the precise structure and algorithms for the main microcomputer 32 can be any combination of hardware and software that will carry out the functions of the present invention. In the illustrated embodiment, the main microcomputer 32 is configured to receive signals and process the signals to at least control an electrically operable derailleur 34 and an electric non-shifting device 36 (e.g., an electrically adjustable suspension, an electrically adjustable seatpost, etc.). The electrically operable derailleur 34 can be either a front derailleur or a rear derailleur. Similarity, for example, the electric non-shifting device 36 can be either a front suspension or a rear suspension. Since electric component for bicycles, such as electrically operable derailleurs, electrically adjustable seatposts and electrically adjustable suspensions, are well known in the bicycle field, details of the electrically operable derailleur 34 and the electric non-shifting device 36 have been omitted for the sake of brevity.
The main microcomputer 32 is programmed to selectively change shift the derailleur 34 in response to a manual input from a rider operating the first and second operating members 16 and 18 or an automatic input from a control program in the main microcomputer 32. In other words, the main microcomputer 32 is configured to selectively change a gear position of the derailleur 34 either manually or automatically. The main microcomputer 32 is also programmed to selectively change various setting states of the electric non-shifting device 36 in response to a manual input from a rider operating the electric switch or an automatic input from a control program in the main microcomputer 32. In other words, the main microcomputer 32 is configured to selectively change at least one electrically adjustable parameter of the electric non-shifting device 36 either manually or automatically.
The bicycle control apparatus further includes a main power supply 38 (e.g., a battery or capacitor as shown) for supplying electrical power to the electric control unit 22 of the bicycle operating device 10, the main microcomputer 32, the derailleur 34 and the electric non-shifting device 36. However, the main power supply 38 is not limited to a battery as a power source. Rather, for example, a generator by itself or a generator with a battery can be used for the main power supply 38. Also the various components of the bicycle control apparatus can be provided with their own individually battery or capacitor instead of receiving power from the main power supply 38.
Here, in the illustrated embodiment, the electric control unit 22 of the bicycle operating device 10, the derailleur 34 and the electric non-shifting device 36 are electrically connected to the main microcomputer 32 by electrical cables that transmit control signals using signal lines S and the transmit power using conductive lines GND and V. However, the main microcomputer 32 can execute two-way communications using electric power line communications (PLC) if needed and/or desired. Moreover, if needed and/or desired, wireless communications could be used to transmit control signals between the main microcomputer 32 and the electric control unit 22 of the bicycle operating device 10, and/or between the main microcomputer 32 and the derailleur 34, and/or between the main microcomputer 32 and the electric non-shifting device 36.
Depending on the configuration of the bicycle, the main microcomputer 32 can also receive control signals from one or more additional bicycle operating devices, and thus, can further be configured to control other bicycle components such as an additional electrically operable derailleur, an additional electrically adjustable suspension and an electrically adjustable seatpost.
As seen in FIG. 3, the base member 10 of the bicycle operating devices includes a fixing member 40 that is configured to be fixed to the bicycle handlebar (hereinafter just “handlebar”) 12 of a bicycle. In the illustrated embodiment, the fixing member 40 is a conventional tube clamp that squeezes the handlebar 12 by tightening a fixing bolt 42. As a result, the first operating member 16 is configured to rotate about the handlebar axis A while the base member 14 is attached to the handlebar 12. Likewise, the second operating member 18 is configured to rotate about the handlebar axis A while the base member 14 is attached to the handlebar 12.
As seen in FIG. 3, the fixing member 40 of the base member 14 includes a handlebar receiving opening 40a defining a handlebar mounting axis B. The handlebar mounting axis B coincides with the handlebar axis A of the handlebar 12 when mounted to the handlebar 12. Thus, the base member 14 is configured to be attached to the handlebar 12 by the fixing member 40. The first operating member 16 is rotatably mounted to the base member 14 about the handlebar mounting axis B. The first operating member 16 is a trigger lever that is biased to a rest position with respect to the base member 14 as explained below. Similarly, the second operating member 18 is a trigger lever that is biased to a rest position with respect to the base member 14 as explained below. The electrical switch 17 is preferably a push switch. The first and second operating members 16 and 18 operate the derailleur 34 (e.g., an electric shifting device), while the electrical switch 17 operates the electric non-shifting device 36 (e.g., an electric non-shifting device).
As seen in FIGS. 8 and 9, the first operating member 16 moves in a first direction (the operating direction R) with respect to the base member 14 as the first operating member 16 is operated. As seen in FIG. 6, the electrical switch 17 is operated in a second direction F, which differs from the first direction (the operating direction R). In the illustrated embodiment, the second direction F is opposite to the first direction (the operating direction R). As seen in FIGS. 10 and 11, the second operating member 18 also moves in the first direction (the operating direction R) with respect to the base member 14 as the second operating member 18 is operated.
The first operating member 16 is movably supported on the base member 14 to perform a first signal. Here, in the illustrated embodiment, the first signal is used for operating an electric shifting device (e.g., the derailleur 34). The electrical switch 17 is detachably disposed on the first operating member 16 to move with the first operating member 16 with respect to the base member 14 and to perform second signal. Here, in the illustrated embodiment, the second signal is used for operating the electric non-shifting device 36 (e.g., a bicycle suspension or a bicycle seatpost). In the case of the electric non-shifting device 36 being a bicycle suspension, then the second signal is used for switching a setting state of the bicycle suspension. The setting state of the bicycle suspension can be, for example, a lock-out setting (i.e., locked or unlocked), a stiffness setting (e.g., hard, medium or soft), etc. In the case of the electric non-shifting device 36 being a bicycle seatpost, then the second signal is used for switching a setting state of a bicycle seatpost. The setting state of the bicycle seatpost can be, for example, a height setting (i.e., low, middle or high), etc. The second operating member 18 biased to a rest position and movably supported on the base member 14 to perform a third signal. Here, in the illustrated embodiment, the third signal is also used for operating an electric shifting device (e.g., the derailleur 34 or another derailleur).
In the illustrated embodiment, as seen in FIG. 3, the base member 14 further includes a first cover member 44, a second cover member 46 and a third cover member 48. The first and second cover members 44 and 46 are snap-fitted together to form a housing that partially encloses the first and second operating members 16 and 18. The third cover member 48 is attached to the second cover member 46 by a plurality (three) of screws 50. The third cover member 48 is fixedly connected to the fixing member 40 by passing the fixing bolt 42 through an opening of the cover member 48. In this way, the first and second cover members 44 and 46 are non-rotatably fixed to the handlebar 12 by the fixing member 40. The first, second and third cover members 44, 46 and 48 are made of a suitable material such as a hard rigid plastic.
Still referring to FIG. 3, in the illustrated embodiment, the base member 14 further includes a first support member 52 and a second support member 54. The first and second support members 52 and 54 are fixed together by a plurality (three) of threaded fasteners 56. The first and second support members 52 and 54 are spaced apart by a plurality (three) of spacers 58a, 58b and 58c. The first and second operating members 16 and 18 are compactly arranged between the first and second support members 52 and 54 as an integrated unit.
As seen in FIG. 4, the second support member 54 preferably has a tubular portion 54a that forms a handlebar receiving part of the base member 14. The tubular portion 54a extends into an opening 52a of the first support member 52 as seen in FIG. 4. Although not shown, preferably, two bearings provided on the tubular portion 54a for rotatably supporting the first and second operating members 16 and 18 on the tubular portion 54a. In other words, a first bearing is disposed between the first operating member 16 and the outer surface of the tubular portion 54a, and a second bearing is disposed between the second operating member 18 and the outer surface of the tubular portion 54a. As seen in FIGS. 5 and 6, the electric control unit 22 is attached to the second support member 54 by a pair of screws 59. The second support member 54 preferably has an opening 54b for receiving portion of the electric control unit 22 to further support the electric control unit 22 on the second support member 54.
Referring to FIGS. 4 and 7 to 11, the first and second operating members 16 and 18 will be now described in more detail. In the illustrated embodiment, as best seen FIG. 4, the first operating member 16 includes a first mounting part 60 and a first lever part 62 (i.e., a first user operating lever). The first mounting part 60 of the first operating member 16 includes a first projection 64 and a second projection 66 for cooperating with the clicking mechanism 20 as discussed below. As best seen FIGS. 7 to 11, the first operating member 16 is a trigger lever that is biased toward a rest position by a biasing element 68 so as to return to the rest position with respect to the fixing member 40 after being operated to an operated position.
As explained below, the first operating member 16 has two operated positions that each causes the electric control unit 22 to generate the first signal. In particular, the electric control unit 22 generates the first signal when the first operating member 16 rotates from the rest position (FIG. 7) to a first operated position (FIG. 9), which corresponds to a fully operated position. The electric control unit 22 also generates the first signal when the first operating member 16 rotates from the rest position (FIG. 7) to a first intermediate position (FIG. 8), which corresponds to a partially operated position between the rest position (FIG. 7) and the first operated position (FIG. 9). More specifically, the first operating member 16 is rotated from the rest position (FIG. 7) by a first prescribed distance D1 to reach the first intermediate position (FIG. 8), and rotated from the rest position (FIG. 7) by a second prescribed distance D2 to reach the first operating position (FIG. 9).
Similarly, in the illustrated embodiment, the second operating member 18 includes a second mounting part 70 and a second lever part 72 (i.e., a second user operating lever). The second operating member 18 is biased toward a rest position by a biasing element 76 so as to return to the rest position after being operated to an operated position. As explained below, the second operating member 18 has two operated positions that each causes the electric control unit 22 to generate the third signal. In particular, the electric control unit 22 generates the third signal when the second operating member 18 rotates from the rest position (FIG. 7) to a second operated position (FIG. 11), which corresponds to a fully operated position. The electric control unit 22 also generates the third signal when the second operating member 18 rotates from the rest position (FIG. 7) to a second intermediate position (FIG. 10), which corresponds to a partially operated position between the rest position (FIG. 7) and the second operated position (FIG. 11). In this embodiment the first and third signals are simultaneously generated when the second operating member 18 rotates from the rest position (FIG. 7) to the second intermediate position (FIG. 10) or the second operated position (FIG. 11), because the first operating member 16 rotates together with the second operating member 18 during operation of the second operating member 18.
In the illustrated embodiment, since both the first and second operating members 16 and 18 use the clicking mechanism 20 to notify the rider when the first and second operating members 16 and 18 have reached the operated position that cause the electric control unit 22 to generate control signals, the first and second operating members 16 and 18 are moved the same amounts to reach the operated positions. More specifically, the second operating member 18 is rotated from the rest position (FIG. 7) by the first prescribed distance D1 to reach the second intermediate position (FIG. 10), and rotated from the rest position (FIG. 7) by the second prescribed distance D2 to reach the second operating position (FIG. 11).
As seen in FIGS. 7 to 11, the first operating member 16 and the second operating member 18 are rotatably supported on the tubular portion 54a of the base member 14 to rotate about the handlebar mounting axis B. As a result, the first operating member 16 is configured to rotate about the handlebar axis A and the handlebar mounting axis B between the rest position and the operated positions while the base member 14 is attached to the handlebar 12. Similarly, the second operating member 18 is configured to rotate about the handlebar axis A between the rest position and the operated positions while the base member 14 is attached to the handlebar 12.
Referring to FIGS. 8 to 12, in the illustrated embodiment, the first operating member 16 and the second operating member 18 are operated from their rest positions (FIG. 7) in an operating direction R (i.e., a rotational direction) that is the same with respect to the handlebar axis A. As seen in FIGS. 9 and 10, the first operating member 16 moves (i.e., rotates) with respect to the base member 14 about the handlebar axis A while the second operating member 18 remains stationary as the first operating member 16 is operated. On the other hand, as seen in FIGS. 11 and 12, the first operating member 16 and the second operating member 18 move together with respect to the base member 14 about the handlebar axis A as the second operating member 18 is operated.
The electric control unit 22 is operated by movement of each of the first and second operating members 16 and 18 moving from their rest positions toward their operated positions, respectively. Specifically, in the illustrated embodiment, the electric control unit 22 generates shift signals as the first and third signals in accordance with movements of the first and second operating members 16 and 18 moving from their rest positions towards their operated positions. For example, the first signals are used as one of an upshift signal and a downshift signal and the third signals are used as the other of the upshift signal and the downshift signal. As described above, the first and third signals are simultaneously generated as the second operating member 18 is operated. The main microcomputer 32 is programmed so that the main microcomputer 32 ignores the first signal in such situation.
In the illustrated embodiment, the first mounting part 60 is rotatably supported on the base member 14 about the handlebar axis A. The first lever part 62 projects outwardly from the first mounting part 60. Preferably, the first operating member 16 is a trigger operating lever that is biased by the biasing element 68 to the rest position of the first operating member 16 with respect to the base member 14. Here, the biasing element 68 is a coil tension spring that has a first end 68a attached to the first operating member 16 and a second end 68b that is attached to the spacer 58a. Thus, when the first operating member 16 is moved from the rest position (FIG. 7) to an operated position (FIG. 9 or 10), the biasing element 68 is stretched so as to apply a biasing force on the first operating member 16. Preferably, the biasing element 68 is loaded (i.e., slightly stretched) while the first operating member 16 is in the rest position (FIG. 7).
In the illustrated embodiment, the second mounting part 70 is rotatably supported on the base member 14 about the handlebar axis A. The second lever part 72 projects outwardly from the second mounting part 70. Preferably, the second operating member 18 is a trigger operating lever that is biased by the biasing element 76 to the rest position of the second operating member 18 with respect to the base member 14. Here, the biasing element 76 is a coil compression spring that has a first end 76a abutting against the second operating member 18 and a second end 76b abutting against the spacer 581). Thus, when the second operating member 18 is moved from the rest position (FIG. 7) to an operated position (FIG. 11 or 12), the biasing element 76 is compressed so as to apply a biasing force on the second operating member 18. Preferably, the biasing element 76 is loaded (i.e., slightly compressed) while the second operating member 18 is in the rest position (FIG. 7).
In the illustrated embodiment, the first lever part 62 and the second lever part 72 are offset relative to each other in a rotational direction of the first mounting part 60 and the second mounting part 70. Also the first lever part 62 and the second lever part 72 are at least partially offset relative to each other in a radial direction of the first mounting part 60 and the second mounting part 70 in the illustrated embodiment. The first lever part 62 and the second lever part 72 have different shapes and different sizes. The first lever part 62 of the first operating member 16 includes a user operating surface 62a and a non-user operating surface 62b. The user operating surface 62a is operated by a user as the first operating member 16 is operated. The non-user operating surface 62b is untouchably arranged as the first operating member 16 is operated. The electrical switch 17 is disposed on the non-user operating surface 62b of the first operating member 16. Likewise, the second lever part 72 of the second operating member 18 includes a user operating surface 72a and a non-user operating surface 72b. The user operating surface 72a is operated by a user as the second operating member 18 is operated. The non-user operating surface 72b is untouchably arranged as the second operating member 18 is operated.
Referring to back to FIGS. 5 and 6, the electrical switch 17 is detachably attached to the first operating member 16 by a pair of screws 78. The electrical switch 17 is a relatively conventional electrical switch that includes a printed circuit board 79 having a push switch SW. The push switch SW is biased in an outward direction from the printed circuit board 79. When a user pushes on the electrical switch 17, a plunger of the push switch SW contacts an electrical contact on the printed circuit board 79 to complete the circuit. As a result, a control signal is generated by the printed circuit board 79. The printed circuit board 79 includes a wireless transmitter to wireless transmit the control signal to the main microcomputer 32 and/or the controller 24 of the electric control unit 22. Alternatively, the electrical switch 17 can be electrical contacted to the electric control unit 22 by a wire that transmits the control signal.
Referring to FIGS. 7, 8 and 13, the clicking mechanism 20 will be now described in more detail. In the illustrated embodiment, as best seen FIGS. 7 and 8, the clicking mechanism 20 includes a first part 80 contacting at least one of the first operating member 16 and the second operating member 18 to produce a haptic feedback response as each of the first and second operating members 16 and 18 moves from the rest position towards the operated position, respectively. In the illustrated embodiment, the first part 80 is only contacted by the first and second projections 64 and 66 of the first operating member 16 because operation of the second operating member 18 moves the first operating member 16 into contact with the first part 80. If the second operating member 18 were configured to operate independently of the first operating member 16, then the second operating member 18 would be provided with projections similar to the first and second projections 64 and 66 for contacting the first part 80. Thus, the clicking mechanism 20 of the illustrated embodiment could be used with a bicycle operating device having independently operable operating members such that the operating members all use the same clicking mechanism.
In the illustrated embodiment, the clicking mechanism 20 further includes a second part 82 pivotally mounted to the second support member 54 of the base member 14 about a first pivot axis P1. The first part 80 is pivotally mounted to the second part 82 about a second pivot axis P2. Specifically, a first pivot pin 84 is fixedly attached to the second support member 54. The first pivot pin 84 defines the first pivot axis P1. The second part 82 is pivotally mounted on the first pivot pin 84. A first biasing element 86 is operatively disposed between the second part 82 and the second support member 54. A second pivot pin 88 pivotally attached the first pivot part 80 to the second part 82. The second pivot pin 88 defines a second pivot axis P2. A second biasing element 90 is operatively disposed between the first part 80 and the second part 82.
The second biasing element 90 applies a biasing force on the first part 80 to normally maintain the first part 80 in a predetermined orientation with respect to the second part 82 such that abutments of the first part 80 and the second part 82 abut each other. As a result, the first part 80 only moves relative to the second part 82 as the first and second projections 64 and 66 contact the first part 80 when the first operating member 16 moves from one of the operated positions towards the rest position. In the illustrated embodiment, the second biasing element 90 is a torsion spring having a coiled portion disposed on the second pivot pin 88. One end of the second biasing element 90 contacts the first part 80, while the other end of the second biasing element 90 contacts the second part 82.
The first biasing element 86 applies a biasing force on the second part 82 to bias the second part 82 such that the first part 80 normally contacts the first operating member 16. In other words, the first biasing element 86 biases the first part 80 into engagement with the first operating member 16 while the first operating member 16 is in the first rest position. As a result of this arrangement of the first and second parts 80 and 82, the first and second parts 80 and 82 move together as a unit as the first and second projections 64 and 66 contact the first part 80 when the first operating member 16 moves from the rest position towards one of the operated positions. In the illustrated embodiment, the first biasing element 86 is a torsion spring having a coiled portion disposed on the first pivot pin 84. One end of the first biasing element 86 contacts the second part 82, while the other end of the first biasing element 86 contacts the second support member 54.
Accordingly during operation of the first and second operating members 16 and 18, the first part 80 rotates about the first pivot axis P1 as each of the first and second operating members 16 and 18 moves from the rest position toward one of the operated positions, respectively. Specifically, the first part 80 contacts one or both of the first and second projections 64 and 66 of the first operating member 16 as each of the first and second operating members 16 and 18 moves from the rest position towards the operated position, respectively. The first part 80 remains stationary with respect to the second part 82 as the first part 80 and the second part 82 pivot together about the first pivot axis P1 as each of the first and second operating members 16 and 18 moves from the rest position towards the operated position, respectively.
On the other hand, during release of the first and second operating members 16 and 18, the first part 80 pivots about the second pivot axis P2, which is offset from the first pivot axis P1, as each of the first and second operating members 16 and 18 moves from one of the operated positions toward the rest position, respectively. As a result, the first part 80 moves with respect to the second part 82 about the second pivot axis P2 as each of the first and second operating members 16 and 18 moves from one of the operated positions towards the rest position, respectively.
As mentioned above, the first operating member 16 includes the first projection 64 and the second projection 66. However, alternatively, the first operating member 16 need only include at least one projection, or the first operating member 16 can include more than two projections. In any case, the number of projections will indicate the number of operated positions that can be attained with the shift operating device. The first and second projections 64 and 66 contact the first part 80 and rotates the first part 80 about the first pivot axis PT as each of the first and second operating members 16 and 18 moves from the rest position towards the operated position, respectively. The first and second projections 64 and 66 also contact the first part 80 and pivots the first part 80 about the second pivot axis P2 as each of the first and second operating members 16 and 18 moves from the operated position towards the rest position, respectively. The first projection 64 has a first height and the second projection 66 has a second height. The first and second heights of the first and second projections 64 and 66 are different from each other. The first projection 64 is closer to the first part 80 than the second projection 66 while the first operating member 16 is at the rest position. The first height of the first projection 64 is smaller than the second height of the second projection 66. By having different heights for the first and second projections 64 and 66, the rider can better distinguish between the two operated positions.
