Description

[0001] Operating device for a bicycle and bicycle with such an operating device

[0002] The present invention relates to an operating device for a bicycle with one or more actuating elements. Furthermore, the invention relates to a bicycle with such an operating device.

[0003] DE 10 2019 206 835 A1 discloses a bicycle control device, particularly for wireless control of, for example, a gearshift. The bicycle control device comprises, among other things, a support element and an operating component and is preferably fixed to the handlebars of a bicycle by means of a clamp. It contains an electronic circuit arrangement connected to two switches. The operating component, which is pivotally mounted on the support element about an operating axis and preloaded into a neutral position, can be deflected from the neutral position in a first direction of rotation about the operating axis in order to actuate the first switch, and can be deflected from the neutral position in a second direction of rotation about the operating axis in order to actuate the second switch.

[0004] The present invention is based on the object of proposing an operating device for a bicycle that is improved in terms of its usability and is ergonomic, simple, and cost-effective. This object is achieved by the subject matter of patent claims 1 and 11. Further advantageous embodiments can be found in the dependent claims.

[0005] According to a first aspect of the invention, an operating device for a bicycle is designed to be fastened to a handlebar of the bicycle in the region of a handlebar grip, wherein the operating device comprises at least one actuating element arranged on a base, wherein the at least one actuating element is arranged to be pivotable from a neutral position by a user's finger about a first actuating axis and at least one second actuating axis in at least one first direction of rotation and about the first actuating axis and / or the at least second actuating axis additionally in a second direction of rotation opposite to the first direction of rotation, wherein at least one functional position can be reached depending on the direction of rotation of the at least one actuating element about the respective actuating axis.

[0006] In other words, the at least one actuating element is pivotally mounted on the base in the first rotational direction about the first actuating axis, starting from the neutral position, in such a way that contact can be established at a first contact point or a first functional position for triggering a first function. The first functional position can be reached when the at least one actuating element has been pivoted relative to the base about the first actuating axis in the first rotational direction up to a first end position.

[0007] In addition, the at least one actuating element is pivotally mounted on the base in the first direction of rotation about the second actuating axis, starting from the neutral position, in such a way that contact can be established at a second contact point or a second functional position to trigger a second function. The second functional position can be reached when the at least one actuating element has been pivoted relative to the base about the second actuating axis in the first direction of rotation up to a second end position.

[0008] Furthermore, in a first alternative embodiment, the at least one actuating element is pivotally mounted on the base from the neutral position in a second rotational direction opposite to the first rotational direction about the first actuating axis such that contact can be established at a third contact point or a third functional position for triggering a third function. The third functional position can be reached when the at least one actuating element has been pivoted relative to the base about the first actuating axis in the second rotational direction up to a third end position.

[0009] In a second alternative embodiment, or in addition to the first alternative embodiment, the at least one actuating element is pivotally mounted on the base, starting from the neutral position, in a second direction of rotation opposite to the first direction of rotation about the second actuating axis such that contact can be established at a fourth contact point or a fourth functional position for triggering a fourth function. The fourth functional position can be reached when the at least one actuating element has been pivoted relative to the base about the second actuating axis in the second direction of rotation up to a fourth end position.

[0010] Accordingly, the at least one actuating element is pivotable in at least one first direction of rotation about the first and second actuating axes, whereas the at least one actuating element is pivotable in the second direction of rotation either only about the first actuating axis or only about the second actuating axis or both about the first and the second actuating axis in order to achieve the respective functional position assigned to the actuating axis in connection with a direction of rotation.

[0011] Preferably, the first actuation axis is arranged substantially parallel to the longitudinal axis of the bicycle. Preferably, the second actuation axis is arranged substantially parallel to the vertical axis of the bicycle. In this case, the first and second actuation axes are arranged at right angles to each other. This allows for simple and ergonomically optimal actuation of the at least one actuation element using a finger, in particular the user's thumb and / or index finger.

[0012] In a further development of the invention, the at least one actuating element is arranged, starting from the neutral position, to pivot about both the first actuating axis and the at least second actuating axis, in the first direction of rotation and the opposite second direction of rotation. In other words, the at least one actuating element is pivotable about both the first actuating axis and the at least second actuating axis in two directions of rotation.

[0013] The neutral position is understood as the initial position of the at least one actuating element. When the at least one actuating element is in the neutral position, no function is triggered. The neutral position is also understood as the position in which a change of direction between the actuating axes can occur.

[0014] After reaching a functional position by actuating at least one actuating element about one of the actuating axes in one of the mentioned directions of rotation, different functions can be triggered which, among other things, can influence the driving operation of the bicycle, transmit a signal or change the operability of the bicycle.

[0015] If the bicycle is a conventional, muscle-powered bicycle that doesn't have a control unit, a corresponding signal can be generated upon reaching one of the aforementioned functional positions, thus initiating or triggering, for example, a gear shift. Thus, the actuation of a switching element can be triggered by reaching a functional position. Furthermore, lights on the bicycle can be switched on or off.

[0016] If the bicycle is an e-bike or pedelec, i.e. a bicycle powered partly by electricity and partly by muscle power, a corresponding signal can be generated upon reaching one of the aforementioned functional positions and transmitted to a control unit of the bicycle. The control unit processes the input commands and, in turn, can generate and transmit command signals to influence the bicycle's operation. In other words, upon reaching a functional position, a predetermined function influencing the operating mode or operation of the bicycle can be initiated, executed, changed, activated, or deactivated. In addition to activating a gearshift, other functions can be triggered, such as adjusting the height of a bicycle saddle, switching an electric motor on and off, and / or setting the level of assistance of the electric motor or a connected transmission.In addition to manual gear changing, an automated gear shifting process with different gear shift characteristics can also be set or selected. Furthermore, the damping level of a bicycle suspension, in particular a suspension fork and / or a suspension rear frame of the bicycle, can be set. Furthermore, a recuperation mode can be activated or deactivated and / or a recuperation level can be set. Furthermore, bicycle lights can be switched on or off, a walking aid can be activated or deactivated, and / or a warning signal, in particular a horn or bell, can be generated or executed. Of course, other bicycle functions not explicitly mentioned here can also be triggered by actuating the at least one actuating element.

[0017] The respective function influencing the operating mode of the electric bicycle preferably includes setting or selecting a defined drive assistance by an electric machine drivingly connected to a bottom bracket drive, setting or selecting a recuperation level of the bottom bracket drive, selecting a switching characteristic in the bottom bracket drive, activating or deactivating a push assist of the electric bicycle, and / or activating or deactivating a headlight and / or a rear light of the electric bicycle. In other words, by actuating the at least one actuating element, depending on the actuating axis and the direction of rotation or the functional position achievable via the direction of rotation and the actuating axis, for example, the type and / or intensity of the drive assistance and / or the type and / or intensity of the recuperation can be influenced.Furthermore, the type of gearshift can be adjusted depending on the actuation axis and the direction of rotation, or the functional position accessible via the direction of rotation and the actuation axis. In particular, the gearshift characteristics can be divided into at least sporty and comfortable gearshifts. With a sporty gearshift characteristic, the gearshift is executed immediately after reaching the assigned functional position. With a comfortable gearshift characteristic, the gearshift is initiated immediately after reaching the assigned functional position, but is not executed until the engine intervenes.With a particularly comfortable shifting characteristic (e.g. "Comfort Plus"), the shifting process is initiated immediately after the assigned functional position is reached, but is only carried out when the pedal crank of the pedal drive is at dead center, i.e. no power is introduced into the system. Furthermore, by appropriately configuring one or more functional positions, an automatic mode of the bottom bracket drive, in which shifting processes are carried out automatically or depending on certain riding or operating conditions, can be activated or deactivated. In addition, a headlight and / or a rear light of the electric bicycle can be activated (i.e. switched on), or deactivated (i.e. switched off), depending on the actuation axis and the direction of rotation or the functional position that can be reached via the direction of rotation. In addition, a headlight and / or a rear light of the electric bicycle can be activated (i.e. switched on), or deactivated (i.e. switched off), depending on the actuation axis and the direction of rotation or the functional position that can be reached via the direction of rotation.A push assist can be activated (i.e., switched on) or deactivated (i.e., switched off) in the functional position that can be reached via the direction of rotation. The push assist can also be used as a starting aid. After each tap of the second actuating element, the second actuating element is released and returns from the respective functional position to the neutral position.

[0018] The at least one actuating element is pivotably mounted on the base such that it can be rotated at least about the first and second actuating axes. The at least one actuating element is, in particular, mounted on the base such that pivoting of the at least one actuating element can occur either only about the first actuating axis or only about the second actuating axis. Conversely, this means that if the at least one actuating element is pivoted, for example, about the first actuating axis, it must first be returned to the neutral position before the actuating element can be pivoted about the second actuating axis. The reverse applies accordingly. This means that the user always knows in which position, in particular in which functional position, the at least one actuating element is currently located. Incorrect operation can thus be easily prevented.

[0019] Preferably, the at least one actuating element is designed and arranged on the base such that the first actuating axis and the at least second actuating axis intersect. In this case, the base can be designed, for example, as a type of joint socket or comprise a joint socket in which a corresponding joint head of the actuating element is received and mounted such that the actuating element can be pivoted about the at least two actuating axes. The at least one actuating element is preferably designed as a lever that can be pivoted about at least the two aforementioned actuating axes.

[0020] Preferably, the at least one actuating element is held in the neutral position by locking and / or preloading. This can be provided for the at least one actuating element with respect to one, several, or all actuating axes. When the at least one actuating element is preloaded, this actuating element can be automatically returned to the neutral position after actuation by releasing it. When the at least one actuating element is locked in the neutral position, it is necessary to overcome a resistance in order to move or pivot the at least one actuating element from the neutral position about the desired actuating axis and the desired direction of rotation.

[0021] Furthermore, the at least one actuating element is preferably held in the functional position by locking after reaching the functional position. Accordingly, the at least one actuating element can only be pivoted actively, i.e., manually, and by overcoming resistance from its current position back to the neutral position or pivoted into another functional position along the same actuating axis. Thus, when the at least one actuating element is locked, a new actuation is required to move the at least one actuating element from the currently set position to a different position, in particular back to the neutral position.

[0022] According to one embodiment, the operating device further comprises an actuation module which is arranged on the at least one actuation element and, starting from a neutral position, is pivotable about a third actuation axis in a first direction of rotation and a second direction of rotation opposite thereto. The actuation module can be a rocker switch, lever or the like which is arranged on the at least one actuation element so as to be pivotable about the third actuation axis. The third actuation axis therefore pivots with the at least one actuation element when it is actuated about the first or at least second actuation axis. Depending on the arrangement and design of the actuation module, the third actuation axis can be aligned substantially parallel to the transverse axis of the bicycle or parallel or coaxial with the longitudinal axis of the actuation element.

[0023] Preferably, the actuating module is arranged at an end of the at least one actuating element that is opposite to the first and second actuating axes. In other words, the actuating module is arranged at the free end of the at least one actuating element.

[0024] Preferably, the actuation module is mechanically lockable, specifically such that, upon actuation of the actuation module about the third actuation axis, pivoting of the actuation element on which the actuation module is pivotally mounted about the first and / or the at least second actuation axis is prevented. In other words, when the actuation module is actuated, the mechanical locking prevents unintentional rotation of the at least one actuation element about the first or second actuation axis.

[0025] Alternatively or additionally, the operating device comprises a pressure switch arranged at an end of the at least one actuating element opposite the first and second actuating axes. The pressure switch is preferably actuable along the longitudinal axis of the actuating element. The pressure switch can be designed, for example, as a push button, in particular as a push-button. Due to its arrangement, the pressure switch is particularly suitable for triggering an acoustic warning signal, in particular a horn or bell signal, or for activating or deactivating a pushing aid.

[0026] In a further development of the invention, the at least one actuating element can be brought into two or more functional positions lying one behind the other in the direction of rotation when actuated in at least one of the directions of rotation about the first or at least second actuating axis. In other words, intermediate positions can be provided between the neutral position and at least one functional position provided at the end position, which intermediate positions can, for example, be designed to be lockable or controllable via pressure points. Therefore, a first actuating force is required to reach a first intermediate position, wherein to reach at least a second intermediate position or the functional position at the end position, a noticeable pressure point must be overcome by a second actuating force that is higher than the first actuating force.In the respective direction of rotation of the actuating axis, preferably two, alternatively three, four or more than four functional positions can be located one behind the other, which are noticeably separated from each other by the user, i.e. the cyclist, during actuation.

[0027] The more functional positions are arranged one after the other, the greater the actuating force required to reach the respective functional position. This allows the user to directly feel which functional position they are in. Alternatively, it is also conceivable that the pressure points for three or more functional positions can each be overcome with the same second actuating force. This makes it comparatively easy or possible to reach a higher functional position with comparatively little actuating force. A pressure point is understood to be a haptic feedback in the form of a perceptibly changed resistance during the actuation of at least one actuating element in the first or second direction of rotation and about the first or second actuating axis.

[0028] With such an operating device, single or multiple gear shifts, such as upshifts or downshifts, can be performed easily without restrictions and with only one operating element. The gear shifts can be performed sequentially, i.e., one after the other. This allows multiple gears or gear steps to be changed quickly one after the other within a short period of time. It is also conceivable that one or more gear steps could be skipped during multiple gear shifts. This depends on the design of the shifting unit of the bottom bracket drive or a transmission integrated into the bottom bracket drive.

[0029] According to one embodiment, the operating device is sealed. For example, a sealing element, e.g., designed as a rubber sleeve or the like, can be provided between the at least one actuating element and the base to protect the interior of the operating device from external influences such as dirt and moisture.

[0030] According to a second aspect of the invention, a bicycle according to the invention comprises a handlebar with two handlebar grips, at least one front wheel and at least one rear wheel, wherein an operating device according to the first aspect of the invention is arranged on the handlebar. The front wheel and / or the rear wheel can be operatively connected, for example via a traction drive, in particular a chain or belt drive, to a driving component at the output of the bottom bracket drive. The bicycle can be a bicycle powered solely by muscle power. However, the bicycle can also be a bicycle powered solely by an electric motor, i.e. an e-bike, or a bicycle powered partly by muscle power and partly by an electric motor, i.e. a pedelec.

[0031] Accordingly, the operating device according to the invention can be advantageously used in electric bicycles, in particular in bicycles designed as e-bikes or pedelecs, since with the proposed operating device a large number of different functions, in particular those influencing the operation of the bicycle, can be conveniently selected, changed, activated, deactivated or controlled.

[0032] The base, on which the at least one actuating element is arranged, is designed for mounting on the handlebar. Accordingly, the base is to be understood as a support element of the operating device, which, on the one hand, can be fastened to the handlebar of the bicycle and, on the other hand, has means for receiving the at least one actuating element. In this sense, the at least one actuating element is arranged on the handlebar via the associated base. The base is arranged in particular in the area of ​​one of the handlebar grips, which the rider holds on to, so that the cyclist can actuate the at least one actuating element in an ergonomically advantageous manner while riding, without having to remove their respective hand from the handlebar. The base can have fastening means for attaching the operating device to the handlebar, such as screws, sleeves and / or clamps. The operating device can have only a single actuating element.Alternatively, the operating device can have two or more actuating elements. If two actuating elements are provided, they can be arranged on the handlebar such that the first actuating element is arranged on the left-hand handlebar grip in the forward direction of travel and can be actuated by a finger, preferably the thumb and / or index finger, of the cyclist's left hand, while the second actuating element is arranged on the right-hand handlebar grip in the forward direction of travel and can be actuated by a finger, in particular the thumb and / or index finger, of the cyclist's right hand. In this sense, it is preferred to arrange a first actuating element of the operating device in the region of the first handlebar grip and a second actuating element of the operating device in the region of the second handlebar grip.In this case, the actuating elements are essentially mirror-inverted, so that one of the actuating elements can be actuated with the left hand and the other actuating element with the right hand.

[0033] The actuating elements are each connected to a control unit to convert the input commands into control signals, allowing the cyclist to directly influence the bicycle's operation. The actuating elements can also be connected to each other.

[0034] The connection between the control unit and the operating device, in particular the at least one actuating element, can be at least partially wired, i.e., via connecting cables or the like, or wireless, for example, via WLAN, a Bluetooth, or a radio connection. Both the control unit and the operating device, or the at least one actuating element, have corresponding transmitting and / or receiving units for data and information exchange.

[0035] The handlebars comprise the handlebar frame and the handlebar grips, with the handlebar frame being pivotably mounted on the rest of the electric bicycle frame. The handlebar grips are designed so that the electric bicycle rider can hold onto them and support themselves. The operating device with at least one actuating element is arranged on the handlebars in such a way that the rider does not have to remove their hand from the handlebar grip to operate the respective actuating element.

[0036] A bicycle driven purely by muscle power has only a pedal crankshaft between the pedals, whereby a drive power is transmitted from the pedal crankshaft as an output part to an input part of the traction drive, in particular to a pinion, in order to drive a wheel of the bicycle.

[0037] A bicycle that is at least partially powered by an electric motor has a bottom bracket drive that is connected to the front and / or rear wheel of the bicycle. A bottom bracket drive refers to a purely electric motor drive (e-bike) as well as a muscle-powered hybrid drive (pedelec). Therefore, the bottom bracket drive can be used for both e-bikes and pedelecs. The bottom bracket drive preferably comprises a drive motor, in particular in the form of an electric machine, and a transmission. An electric machine has a stator fixed to the housing and a rotor rotatably arranged thereon. The rotor is connected to the transmission for driving purposes.The transmission is designed to be operatively connected, by a first transmission element, at least indirectly to a pedal crankshaft of the electric bicycle, and by a second transmission element, at least indirectly to a chain or belt pinion of the electric bicycle. The transmission can be a planetary transmission with at least one planetary gear set, wherein each planetary gear set comprises the gear set elements sun gear, ring gear, and planet carrier. Each of these gear set elements is to be understood as a transmission element within the meaning of this invention. The transmission can further comprise shifting elements for implementing different gear stages. The bottom bracket drive can further comprise a control unit according to the previous embodiments, which receives the input commands generated via the at least one actuating element and converts them into corresponding control and regulation commands on the electric machine and / or on the transmission of the bottom bracket drive.

[0038] The bottom bracket drive further comprises a transmitter and receiver unit designed to communicate with an external device, in particular a computer or a smartphone. Configurations of the control device can be made via the transmitter and receiver unit. In particular, the functional positions or the function triggered when the respective functional position is reached can be defined and / or adjusted. Furthermore, pressure points, in particular the required actuation force for each pressure point, can be adjusted, if present.

[0039] The bottom bracket drive preferably comprises means for decoupling kinematic energy from the chain or belt pinion, wherein the kinematic energy can be used for recuperation. Such a decoupling means can, for example, be a freewheel, which is designed to decouple kinematic energy from the chain or belt pinion, wherein the kinematic energy can be used for recuperation. Thus, electrical energy can be recovered, which is generated during the electric bicycle's overrun mode and fed into the energy storage device and stored or kept there. To achieve recuperation, the electric machine in generator mode can reduce or decelerate the rotational speed or speed of the pinion or rotor, whereby electrical energy is consequently generated, which is fed into the energy storage device and stored.Recuperation can be initiated, for example, by pedaling backwards, which further increases driving safety.

[0040] The above definitions as well as explanations of technical effects, advantages, and advantageous embodiments of the operating device according to the first aspect of the invention also apply mutatis mutandis to the bicycle according to the second aspect of the invention, and vice versa. It is understood that features of the solutions described above or in the claims and / or figures can also be combined if necessary in order to achieve the cumulative advantages and effects achievable here.

[0052] According to Fig. 1, a bicycle 2 designed as an electric bicycle is shown, comprising a front wheel 20 and a rear wheel 21, wherein the rear wheel 21 is connected via a chain 24 of a chain drive to a bottom bracket drive 3 arranged in the bottom bracket area of ​​the bicycle 2. The electric bicycle is a bicycle 2 with electric assistance (pedelec) and derailleur gears. The bottom bracket drive 3 has a chain pinion 19 via which the chain 24 can be driven. The bottom bracket drive 3 further comprises a control unit 25, which is connected for control purposes to an operating device 1 and an electric machine 16 of the bottom bracket drive 3. The bottom bracket drive 3 is supplied with electrical energy to drive the bicycle 2 via a battery (not shown here), which is fed into the bottom bracket drive 3 in a manner not described in detail.The bottom bracket drive 3 further comprises a gear 22, which can be designed, for example, as a switchable planetary gear. The gear 22 is configured to be operatively connected, by a first gear element, at least indirectly to a pedal crankshaft 23 of the bicycle 2, and by a second gear element, at least indirectly to the chain pinion 19 of the electric bicycle 2. The bottom bracket drive 3 further comprises means for decoupling kinematic energy from the chain pinion 19, wherein the kinematic energy can be used for recuperation. This merely clarifies that the bottom bracket drive 3 is configured for recuperation. Recuperation can be achieved, for example, by backward pedaling of pedals 26, which are connected in a rotationally fixed manner to the pedal crankshaft 23, or by pulling a brake lever (also not shown here).

[0053] The bicycle 2 further comprises a handlebar 4 with two handlebar grips 5, 6 attached to a handlebar frame 4a. The operating device 1 is attached to the handlebar frame 4a in the area of ​​one or both handlebar grips 5, 6. The structure and function of the operating device 1 are described in more detail below with reference to the other figures.

[0054] Fig. 2a to Fig. 2d show a first embodiment of the operating device 1. The operating device 1 here comprises an actuating element 7, which is fastened via a base 14 in the area of ​​the right handlebar grip 5 to the handlebar frame 4a of the handlebar 4 and can be actuated by the right hand of the cyclist. The actuating element 7 is arranged on the base 14 so as to be pivotable about a first actuating axis A1 and a second actuating axis A2. The actuating element 7 is designed and mounted and arranged on the base 14 such that the first actuating axis A1 and the at least second actuating axis A2 intersect at an intersection point X. The mounting of the actuating element 7 about the two actuating axes A1 and A2 is shown in a highly simplified manner in Fig. 2c. In addition, Fig. 2c shows an exemplary fastening of the base 14 to the handlebar grip, namely by means of a screw connection 29.

[0055] According to Fig. 2a, the handlebar frame 4a of the handlebar 4 is shown from behind in the forward direction of travel of the bicycle 2. Accordingly, the actuating element 7 is articulated and mounted on the base 14 in such a way that, starting from a neutral position 13, it can be pivoted, in particular by the user's index finger or thumb, about a first actuating axis A1 shown in Fig. 2b in a first direction of rotation 9. The first actuating axis A1 is aligned substantially parallel to the longitudinal axis L of the bicycle 2. The actuating element 7 is shown here in the neutral position 13 on the one hand and in an upwardly pivoted position, which corresponds to a first functional position F1 of the actuating element 7, on the other hand. The pivoting direction of the actuating element 7 about the first actuating axis A1 and in the first direction of rotation 9 is indicated in Fig. 2d by a first arrow P1.

[0056] By actuating the actuating element 7 about the first actuating axis A1 in the first rotational direction 9, i.e., upwards, switching between a manual shifting mode and an automatic shifting mode can occur, for example. Alternatively, a height adjustment of a saddle 27 of the bicycle 2 can be initiated or executed. Furthermore, alternatively, a damper adjustment or a selection from several damper settings can be made by tapping the actuating element 7 once or several times, with optionally preloaded return. For example, a selection can be made between a normal ride mode, a trail mode, and / or a downhill mode.

[0057] Fig. 2b shows that the actuating element 7, starting from the neutral position 13, can also be pivoted by the cyclist's thumb or index finger about a second actuating axis A2 shown in Fig. 2a in a first direction of rotation 9 and a second direction of rotation 10 opposite thereto. Fig. 2b shows the actuating element 7 in plan view or essentially from the cyclist's perspective, wherein the actuating element 7 is shown in the neutral position 13 on the one hand and is indicated on the one hand in a forwardly pivoted position, which corresponds to a second functional position F2 of the actuating element 7, and on the other hand in a rearwardly pivoted position, which corresponds to a third functional position F3 of the actuating element 7. The second actuating axis A2 is aligned essentially parallel to the vertical axis H of the bicycle 2.The pivoting direction of the actuating element 7 about the second actuating axis A2 and in the first rotational direction 9 is indicated in Fig. 2d by a second arrow P2. The pivoting direction of the actuating element 7 about the second actuating axis A2 and in the second rotational direction 10 is indicated in Fig. 2d by a third arrow P3.

[0058] By actuating the actuating element 7 about the second actuating axis A2 in the first or second direction of rotation 9, 10, i.e. forwards or backwards, for example, a shift between gears, i.e. an upshift or downshift, can take place. Alternatively or additionally, the shifting characteristics can be changed. In particular, it is possible to switch sequentially between a relaxed shifting characteristic, a comfort shifting characteristic, a touring shifting characteristic, a city shifting characteristic and / or a sport shifting characteristic. Analogous to the above explanations, it is also possible, alternatively or additionally, to switch between a manual and automatic mode on the gearshift and / or to switch between damper settings. Thus, depending on the direction of rotation 9, 10 of the actuating element 7 about the respective actuating axis A1, A2, at least one functional position F1, F2, F3 can be achieved.

[0059] The actuating element 7 is designed in the form of a lever and, according to Fig. 2a and Fig. 2b, has on the one hand at a free end an actuating lip 30 for easier actuation of the actuating element 7 about the second actuating axis A2 and, on the end facing the base 14, a ball head 31 for limitedly articulated mounting of the actuating element 7 in a joint socket 32 ​​of the base 14.

[0060] Fig. 3a to Fig. 3d show a second embodiment of the actuating element 7, wherein only the differences from the embodiment according to Fig. 2a to Fig. 2d are discussed below.

[0061] According to Fig. 3a, the handlebar frame 4a of the handlebar 4 is shown from behind in the forward direction of travel of the bicycle 2. Accordingly, the actuating element 7 is pivotally mounted on the base 14 in such a way that the actuating element 7, starting from a neutral position 13, can be pivoted, in particular by the right thumb or right index finger of the cyclist, about a first actuating axis A1 shown in Fig. 3b, in a first direction of rotation 9 and an opposite second direction of rotation 10. The first actuating axis A1 is aligned substantially parallel to the longitudinal axis L of the bicycle 2.The actuating element 7 is shown here on the one hand in the neutral position 13 and on the other hand in an upwardly pivoted first position, which corresponds to a first functional position F1 of the actuating element 7, as well as in a downwardly pivoted second position, which corresponds to a second functional position F2 of the actuating element 7.

[0062] Fig. 3b shows the actuating element 7 in a top view, or essentially from the cyclist's perspective. According to Fig. 3b, the actuating element 7 can be pivoted from the neutral position 13 by the cyclist's right thumb about a second actuating axis A2 shown in Fig. 3a in a first direction of rotation 9. The actuating element 7 is shown in Fig. 3b in the neutral position 13 and is also indicated in a forwardly pivoted position, which corresponds to a third functional position F3 of the actuating element 7. The second actuating axis A2 is arranged essentially parallel to the vertical axis H of the bicycle 2.

[0063] With regard to the function that can be realized by actuating the actuating element 7 according to Fig. 3a to Fig. 3d, reference is made to the above explanations regarding the embodiment according to Fig. 2a to Fig. 2d.

[0064] The actuating element 7 is also designed in the form of a lever here. A key difference from the first exemplary embodiment according to Fig. 2a to Fig. 2d is that the actuating element 7 further comprises an actuating module 15 in the form of a rocker switch, which is arranged on the at least one actuating element 7, 8 and, starting from the neutral position 13, is pivotable about a third actuating axis A3 in a first direction of rotation 9 and a second direction of rotation 10 opposite thereto. The actuating module 15 is arranged at a free end of the actuating element 7 opposite the intersection point X and is connected to the remaining actuating element 7 in such a way that when the actuating module 15 is actuated, the actuating element 7 also pivots about the third actuating axis A3.

[0065] The actuating module 15 has two legs 15a, 15b which are integrally connected to the rest of the actuating element 7, the first leg 15a being provided for actuating the actuating element 7 about the third actuating axis A3 in the first direction of rotation 9, and the second leg 15b being provided for actuating the actuating element 7 about the third actuating axis A3 in the opposite second direction of rotation 10. The third actuating axis A3 crosses the first and second actuating axes A1, A2 at the intersection point X and pivots with the actuating element 7 when actuated about the first or second actuating axis A1, A2. The third actuating axis A3 is parallel to the longitudinal axis of the actuating element 7 or parallel to a transverse axis Q of the bicycle, provided the actuating element 7 is in the neutral position 13.

[0066] The actuating element 7 is shown in Fig. 3d on the one hand in the neutral position 13, wherein upon pivoting of the actuating module 15 in the first direction of rotation 9, here clockwise, a fourth functional position F4 of the actuating element 7 or the actuating module 15, which is only indicated, can be reached, and wherein upon pivoting of the actuating module 15 in the opposite direction in the second direction of rotation 10, here counterclockwise, a fifth functional position F5 of the actuating element 7 or the actuating module 15, which is also only indicated, can be reached.

[0067] Thus, depending on the direction of rotation 9, 10 of the actuating element 7 about the respective actuating axis A1, A2, A3, at least one functional position F1, F2, F3, F4, F5 can be reached.

[0068] The actuation module 15 is mechanically lockable such that, when the actuation module 15 is actuated about the third actuation axis A3, pivoting of the actuation element 7, on which the actuation module 15 is pivotally mounted, about the first and / or second actuation axis A1, A2 is prevented. The mechanical locking is achieved via a locking element 12, shown in Fig. 3c, which is integrally connected to the lever-shaped actuation element 7. The locking element 12 is indicated here in the three positions mentioned above, analogous to the rocker switch.

[0069] Fig. 4a to Fig. 4c show a third embodiment of the operating device 1. The operating device 1 comprises an actuating element 8, which is attached to the handlebar frame 4a of the handlebar 4 via the base 14 in the area of ​​the left handlebar grip 6.

[0070] The actuating element 8 according to the third embodiment shown in Fig. 4a to Fig. 4c is essentially identical to the actuating element 7 according to the second embodiment shown in Fig. 3a to Fig. 3d. The differences are that the actuating element 8 according to Fig. 4a to Fig. 4c is, on the one hand, a mirror image of the actuating element 7 according to Fig. 3a to Fig. 3d. In addition, the actuating element 8 according to the third embodiment has a push button switch 28 which is arranged on the front side at a free end of the actuating element 8 which is opposite the intersection point X. The push button switch 28 is a push button which can be actuated in an actuating direction 11 along the third actuating axis A3 in order to be actuated from a neutral position according to the illustration according to Fig. 4a and Fig. 4b into a sixth functional position - not shown here.The push button switch 28 is arranged coaxially with the third actuation axis A3. For example, a bell or a push assist can be activated using the push button switch 28. Alternatively, a front headlight 17 or a rear light 18 of the bicycle 2 can be turned on or off.

[0071] The advantages of such an operating device 1 are, firstly, that it is intuitive to use. In particular, several functions, operating modes, or different switching operations can be triggered with one or at most two actuating elements 7, 8. Furthermore, driving safety can be increased because the handlebars can be clamped with the hands at all times. The respective thumb or index finger only needs to move slightly from the position of the optimal handlebar clamp. Furthermore, various additional functions, such as setting a switching characteristic, can be implemented, which can also be adjusted with the described actuating element 7, 8.

[0072] The exemplary embodiments shown and described here are intended to make it clear that by reducing the number of actuating elements 7, 8 and by cleverly designing the operating device and assigning functions to functional positions, intuitive, almost blind operation of the operating device 1 is possible. The actuating elements 7, 8 are arranged on the respective handlebar grip 5, 6 in such a way that the rider can actuate them with their thumb and, if applicable, index finger without removing their hand from the handlebar grip 5, 6. Accordingly, a first actuating element 7 of the operating device 1 can be arranged in the area of ​​the first handlebar grip 5 and a second actuating element 8 of the operating device 1 can be arranged in the area of ​​the second handlebar grip 6.

[0073] It is also conceivable that one of the actuating elements 7, 8 described as examples is arranged, if necessary by means of a mirror-inverted design, on the right handlebar grip 5 and the same or another of the actuating elements 7, 8 described is arranged, if necessary by means of a mirror-inverted design, on the left handlebar grip 6.

[0074] It is also conceivable that the at least one actuating element 7, 8 is held in the neutral position 13 by locking and / or preload. Accordingly, the respective actuating element 7, 8 returns to the neutral position 13 upon release. Alternatively or additionally, it is possible to hold the at least one actuating element 7, 8 in this position by locking after reaching the functional position.

[0075] It is also possible for the actuating element 7 to be pivoted from the neutral position 13 about the second actuating axis A2 in a second direction of rotation opposite to the first direction of rotation 9 in order to realize further functions with the existing actuating axes A1 and A2.

[0076] In order to cover as many functions as possible with a single actuating element 7 or 8 and the existing actuating axes A1, A2, A3 already described above, it can be advantageous if the respective actuating element 7, 8, when actuated in at least one of the directions of rotation 9, 10 about the first, the second and / or the third actuating axis A1, A2, A3, can be brought into two or more functional positions F1, F2 or intermediate positions lying one behind the other in the direction of rotation 9, 10. Accordingly, the respective actuating element 7, 8, starting from the neutral position 13, can be brought into two or more functional positions in each of the two directions of rotation 9, 10, which can be arranged one behind the other in the respective direction of rotation 9, 10 about the associated actuating axis A1, A2, A3. In the respective direction of rotation 9, 10, a respective pressure point perceptible by the cyclist can be provided between each two functional or intermediate positions.To reach a first functional position, a first actuating force is required. To reach a second functional position lying behind the first functional position, however, the first pressure point must be overcome by a second actuating force that is higher than the first actuating force. Alternatively, instead of pressure points, locking points can be implemented, whereby the respective actuating element 7, 8 engages when the functional position or intermediate position is reached. Adjustment of the respective actuating element 7, 8 into the neutral position 13 or another functional or intermediate position is only possible by renewed manual actuation of the respective actuating element 7, 8 about the corresponding actuating axis A1, A2, A3 and overcoming a noticeable resistance.
