Description

[0001] The present invention relates to a bicycle actuation device, here also referred to as actuation device, with the features of the preamble of claim 1.

[0002] Such a conventional bicycle actuation device, as known, for example, from documents US 8061667 B2 and US 8061667 B2, comprises a main body, in particular in the form of a housing, an actuation element preferably movably mounted on the main body, and a mounting section with at least one mounting opening for attaching the bicycle actuation device to a handlebar clamp of a bicycle.

[0003] Modern bicycles have a multitude of controllable components, such as derailleurs, seatposts, shock absorbers or suspension forks, brakes, e-bike motors, etc. For easy access and safe operation, even while riding, the controls for all these components are usually mounted on the handlebars of the bicycle, making the space-saving, ergonomic positioning of the various controls, adaptable to the different needs of different riders, of great importance.

[0004] Mounting each individual actuating device with a separate handlebar clamp would lead to space and accessibility problems. Therefore, solutions are known from the aforementioned prior art in which different actuating devices can be attached to different circumferential positions of a single handlebar clamp using appropriate clamp adapters; however, this can negatively affect the accessibility of the individual actuating devices.

[0005] Against this background, the object of the present invention is to improve the known bicycle actuation device with regard to the flexible and space-saving arrangement of several devices on a single handlebar clamp.

[0006] To solve this problem, it is proposed according to the invention that the fastening section projects away from the main body and that the fastening opening is designed as a through-opening that connects two opposing fastening surfaces of the fastening section.

[0007] In contrast to the prior art, in which the mounting openings of the bicycle actuation devices are designed as blind holes, the solution according to the invention makes it possible to fix several components to each other and to a handlebar clamp at the same circumferential position with a single fastening means that passes through the mounting opening, wherein the mounting surface of the fastening section facing away from the handlebar clamp serves as a mounting surface for another component.

[0008] In order to be able to vary the position of the bicycle actuation device according to user preference, the mounting section can be designed as an elongated bridge and have several mounting openings arranged along a first predetermined direction, designed as through openings, wherein the mounting section preferably also projects from the main body in this first direction.

[0009] Positioning can be facilitated by ensuring that the mounting section has, at least in sections, a constant cross-sectional contour perpendicular to the first predetermined direction. This allows relative movement between the bicycle control device and the additional component or handlebar clamp to be attached along the first direction before it is fixed with the fastener. In particular, the mounting section can act as a rail to guide the bicycle control device relative to the handlebar clamp or to guide another component relative to the bicycle control device along the first predetermined direction.

[0010] According to a preferred embodiment of the invention, it is further provided that the two opposing mounting surfaces of the mounting section are designed such that the mounting section and a further, separate component, which at least partially has essentially the same shape as the mounting section, can be stacked on top of each other in any order along a second predetermined direction, wherein the second predetermined direction runs parallel to an axial direction of the at least one mounting opening of the mounting section and preferably also perpendicular to the first predetermined direction.

[0011] This additional component could, for example, be a spacer or another bicycle operating device, as explained in more detail below.

[0012] To achieve the desired stackability, it can be provided in particular that the two opposing fastening surfaces of the fastening section are at least partially complementary to each other, i.e., for each recess on one fastening surface in the relevant section, there is a corresponding projection in the other fastening surface that fits or would fit into the recess, and vice versa.

[0013] As a positioning aid, the fastening section can also be designed in such a way that the fastening section and the other component, when stacked on top of each other, engage (positive locking engagement) in such a way that a mutual relative movement in and against a third predetermined direction is prevented, which runs perpendicular to the second predetermined direction and preferably also perpendicular to the first predetermined direction.

[0014] It should also not be ruled out that the fastening section has structures so that the fastening section and the other component, when stacked on top of each other, adhere to each other at least temporarily in the manner of building blocks, so that the user does not have to hold the stacked and pre-positioned components during the final fixing with a fastener.

[0015] Furthermore, protection is also claimed for a bicycle actuation system (hereinafter referred to as actuation system) with at least one bicycle actuation device according to the invention, as described in the introduction, and at least one spacer designed separately from the bicycle actuation device.

[0016] The spacer has at least one mounting opening designed as a through-opening, preferably several mounting openings designed as through-openings arranged in a line, and is configured to be selectively mounted on either of the two mounting surfaces of the mounting section of the bicycle actuation device, so that the at least one mounting opening of the bicycle actuation device and the at least one mounting opening of the spacer are arranged coaxially to each other, so that the spacer and actuation device can be attached to each other and preferably also to the handlebar clamp with a single fastening means that passes through the coaxial openings.

[0017] With one or more such spacers, depending on hand size and preferences, the distance to the handlebar and / or the distance between different stacked components (actuating devices) can be adjusted, wherein the interfaces between the components or the components and the spacers preferably interlock in a form-fitting manner, particularly in the manner of clamping blocks.

[0018] A bicycle actuation system, in particular a system with spacers as described above, can comprise, in addition to the bicycle actuation device according to the invention, a handlebar clamp, wherein the bicycle actuation device and the handlebar clamp are configured to mount the bicycle actuation device on the handlebar clamp, preferably with the same fastening means with which at least one further component can be mounted on the bicycle actuation device.

[0019] Preferably, the bicycle actuation system also includes a fastening means, for example in the form of a screw or a screw-nut combination, with which the actuation device(s) and, if applicable, the spacer can be mounted together in a stacked state at a preferably selected circumferential position of the handlebar clamp.

[0020] For an actuating device with several mounting openings arranged in a line along the first predetermined direction, the first direction, in the state of the actuating device being attached to the handlebar clamp, preferably runs essentially parallel to an axis of the handlebar clamp, so that in the mounted state an adjustment of the position of the actuating device relative to the clamp in the direction of the handlebar axis is possible.

[0021] Furthermore, the bicycle actuation device may include a brake actuation device, preferably configured to be mounted between the circumferential ends of the handlebar clamp. However, it is also possible to mount a brake actuation device to the handlebar clamp or to a separate clamp in another suitable manner.

[0022] In principle, it should not be ruled out to use special handlebar clamps designed to mount the bicycle control device directly on the clamp at a single fixed circumferential position.

[0023] Preferably, the bicycle actuation system comprises a clamp adapter designed separately from the clamp, which is configured to be selectively attached to the handlebar clamp in various circumferential positions, and which further comprises a mounting section with at least one mounting opening, wherein the mounting section of the bicycle actuation device is configured to be attached directly or indirectly, for example by means of an intermediate spacer, to the mounting section of the clamp adapter, such that the mounting opening of the handlebar clamp and the at least one mounting opening of the bicycle actuation device are coaxial with each other. Corresponding handlebar clamps and clamp adapters are known, for example, from the two introductory publications.

[0024] In one embodiment, the bicycle actuation system can further comprise another, preferably also according to the invention, bicycle actuation device with a mounting section and a mounting opening formed therein, wherein the two actuation devices can be mounted together to form an assembly in such a way that their two mounting sections are stacked on top of each other, so that the at least one mounting opening of the mounting section of one bicycle actuation device and the at least one mounting opening of the mounting section of the other bicycle actuation device are arranged coaxially to each other.

[0025] In a bicycle actuation system with two bicycle actuation devices, a handlebar clamp and at least one spacer, as described above, it can be provided in particular that the spacer and the two actuation devices can be mounted together or stacked on top of each other in different configurations and attached to the handlebar clamp, in particular with a single fastening means, such as a screw or a bolt, wherein in one of the configurations the spacer is arranged between the mounting sections of the two bicycle actuation devices, and in another of the configurations it is arranged between the handlebar clamp and the mounting sections of the two actuation devices that are mounted directly together.

[0026] The individual control devices could be, for example, a derailleur control device, a seatpost control device (dropper remote), an e-bike controller or a bicycle computer.

[0027] The present invention will now be explained in more detail with reference to some selected embodiments, which are illustrated in the accompanying figures. These show: Fig. 1 a bicycle actuation device in the form of an e-bike controller according to a first embodiment of the present invention in a first perspective view, Fig. 2 the subject matter of claim 1 in a second perspective view, Fig. 3.

[0028] Identical or corresponding features of different embodiments are each identified with the same reference numeral. For the sake of clarity, not all features are always provided with a reference numeral, but primarily those used to explain the respective embodiment. If several recognizably identical features are present, a reference numeral is not always provided for each feature.

[0029] As mentioned above, the Fig. 1 and Fig. 2 A bicycle actuation device 10, here in the form of an e-bike controller 10A, according to a first embodiment of the present invention in various views. The actuation device 10 comprises a main body 12, which here is designed in the form of a housing in which the battery and electronics of the controller are housed. A battery compartment cover 15 on the rear of the housing allows the battery to be replaced.

[0030] Actuating elements 14 are two rockers mounted on two separate axes A14 movably on the main body 12 and serve, for example, to operate three or more electronic switches not visible here, which may also be assigned multiple functions depending on the type or duration of the actuation.

[0031] A fastening section 16 designed as an elongated bridge projects laterally away from the main body 12 in a first predetermined direction R1, and several fastening openings 18 are formed in the fastening section 16 arranged along a line in the first direction R1.

[0032] According to the invention, the fastening openings 18 are designed as through openings and connect two opposing fastening surfaces 20, 22 of the fastening section 16, one of which is shown in the view in Fig. 1 is recognizable, the other in the view of Fig. 2.

[0033] The axes A18 of the mounting openings 18 extend parallel to each other in a second predetermined direction R2, which is perpendicular to the first direction R1, and which is best seen in the cross-sectional view of Fig. 3 can be seen.

[0034] The section plane of the view of Fig. 3 runs perpendicular to the first given direction R1 and its position is in Fig. 1 indicated by a dashed line and labelled III-III.

[0035] In Fig. Figure 3 shows that the fastening section 16 is specifically designed such that the fastening section 16 and a separate component with at least partially essentially the same shape as the fastening section 16 can be stacked on top of each other in any order along the second specified direction R2.

[0036] In particular, the two fastening surfaces 20, 22 are at least partially complementary to each other, for example in the Fig. 3 areas designated Z1 and Z2 respectively, so that in the case of two identical fastening sections, e.g. the actuating device and the separate component, a trapezoidal projection 20p formed on the fastening surface 20 of one fastening section fits into a corresponding trapezoidal recess 22r formed on the fastening surface 22 of the other fastening section and rests against it, and vice versa.

[0037] One such additional component 25, which is stackable in any order in combination with the fastening section 16 in the direction R2, can for example be a spacer 30, which together with the bicycle actuation device 10 according to the Fig. 1-3 Part of a bicycle actuation system 100 according to an embodiment of the invention, which can be shown in different views in the Fig. 4-7 is shown.

[0038] For the sake of completeness, it should be noted that the operating device 10 of the Fig. 1-3 is designed for mounting on the right side of the handlebars, the system of the following Fig. 4-11 but for mounting on the left side of the handlebars, so that the components are designed accordingly in a mirror-symmetrical manner.

[0039] The spacer 30 can be used, for example, to vary the distance, preferably the radial distance, between the actuating device 10 and the handlebar, or the distance between the actuating device 10 and another component. Several stackable and, in particular, identical spacers 30 can also be used to vary the amount of the distance.

[0040] As particularly evident in the exploded view in Fig. 7 and the side view in Fig. As can be seen in Figure 6, the spacer 30 has essentially the same shape as the fastening section 16, in particular in cross-section in a section plane perpendicular to the first direction R1.

[0041] The matching and interlocking structures of fastening section 16 and spacer 30 act like rails to guide a relative movement of the two components 10, 30 along the first direction R1 and to prevent a relative movement in and against a third direction R3, which runs perpendicular to both the first direction R1 and the second direction R2.

[0042] In the side view of the Fig. Figure 6 clearly shows that the shape of the back surfaces 14r of the actuating surfaces 14f of the actuating elements 14 of the bicycle actuating device 10 is adapted to the curvature of a handlebar L so that the actuating device 10 can be positioned particularly close to the handlebar L (cf. Fig. 11).

[0043] The actuation system 100 of the Fig. 4, Fig. 5, Fig. 6 to Fig. 7 further comprises a screw 70 with a nut 80 as a fastening means to fix the adapter 30 on or under the mounting section 16, i.e., on any one of the two mounting surfaces 20, 22. The screw 70 and the associated nut 80 are to be considered a single fastening means.

[0044] The Fig. Figures 8-11 illustrate a further embodiment of a bicycle actuation system 100 according to the invention.

[0045] Fig. Figure 8 shows the actuation system 100 in its assembled state. In addition to the e-bike controller 10A shown in all previous figures, it comprises, as the first bicycle actuation device 10 according to the invention, a second, preferably also according to the invention, bicycle actuation device 10, here as a seatpost actuation device 10B (dropper remote), as well as a handlebar clamp 50 with clamp adapter 60 and a brake actuation device 90, which, however, are shown in the Fig. 9 and Fig. 10 is not shown.

[0046] If it becomes necessary to distinguish between the two bicycle operating devices, the reference numerals of the components of the e-bike controller 10A will also be given the suffix A, and the reference numerals of the components of the seat post operating device 10B will be given the suffix B.

[0047] Unless a distinction is important, the suffixes can be omitted.

[0048] The brake actuation device 90 can be fixed in a known manner between the two free circumferential ends 51, 52 of the handlebar clamp 60.

[0049] Handlebar clamp 50 and clamp adapter 60 are designed in the present example as shown in the embodiments of US8061667B2, to whose more detailed description reference may be made here.

[0050] The clamp adapter 60 can be positioned in various circumferential positions on the clamp 50 and fixed in the selected position with a screw 65 and a specially designed screw nut (not visible here) on the handlebar clamp 50.

[0051] Furthermore, the clamp adapter 60 has a mounting section 66 with a mounting opening 68. The mounting sections 66, 16A of the clamp adapter 60 and the bicycle actuating device 10A are designed such that, with a coaxial arrangement of the mounting openings 68, 18A, the actuating device 10A can be attached directly or indirectly (e.g., by means of an intermediate spacer 30) to the clamp adapter 60 with a single fastening means 70, 80.

[0052] As in Fig. As can be seen in Figure 8, in the assembled state the first predetermined direction R1 of the first actuating device 10 runs essentially parallel to the axis A50 of the handlebar clamp 50, so that by selecting the mounting opening 18A of the actuating device 10A that is used for attachment to the clamp 50, the axial position of the actuating elements 14A relative to the handlebar clamp 50 and thus, for example, relative to the brake lever 92 or handlebar grip 95 can be adjusted (see Figure 8). Fig. 11).

[0053] The second bicycle actuation device 10, here the seatpost actuation device 10B (Dropper Remote), is fundamentally similar in design to the first actuation device 10A, with a main body 12, a movable pivot lever as actuation element 14 and a rib-like mounting section 16 with three mounting openings 18 arranged along a line in the first predetermined direction R1, designed as through openings, which make it possible to vary the position of the second actuation device 10B relative to the first actuation device 10A in the first direction R1.

[0054] Unlike the e-bike controller 10A, the fastening section 16B of the actuating device 10B does not protrude in the first specified direction R1, but in the third specified direction R3 from the main body 12B.

[0055] Since in some cases a specific stacking sequence of the various actuating devices 10 to be attached to the same circumferential position of the handlebar clamp 50 may be predetermined, for example because the positions of the various actuating elements 14 are specifically adapted to this sequence with regard to good accessibility, the mounting openings 18 of the actuating device 10 (here 10B) that is to be attached radially furthest from the handlebar clamp 50 need not necessarily be designed as through openings, unlike in the figures. Accordingly, the mounting section of this actuating device need not necessarily protrude from its main body.

[0056] If an internal thread is provided in the mounting holes of the actuating devices to be positioned furthest from the clamp, a separate screw nut may be unnecessary.

[0057] All actuating devices 10A, 10B of the bicycle actuating system 100 can be attached to a single circumferential position of the handlebar clamp 50 with a single fastening device 70.

[0058] Fig. Figure 11 shows the bicycle actuation system 100 of the Fig. Figures 8-10 show the components mounted on the handlebar L of a bicycle 150. It can be seen that, due to the stacked arrangement according to the invention, the actuating elements 14 of the various actuating devices 10A, 10B are easily accessible at the same circumferential position of the handlebar clamp 50, even without repositioning the hand.

[0059] As already mentioned, the shape and position of the actuating elements 14A of the e-bike controller 10A in the illustrated embodiment are adapted to be positioned particularly close to the handlebar L.

[0060] Does this lead to space problems, for example because the clamp 50 is to be positioned axially closer to the handlebar grip 95 than in Fig. As shown in 11, a spacer 30 (not shown here), such as that used in 11, can be used. Fig. Figure 7 illustrates that it is installed between the mounting section 66 of the handlebar clamp 50 or the clamp adapter 60 and the mounting section 16A of the e-bike controller 10A.

[0061] Alternatively or additionally, such a spacer 30 can also be mounted between the mounting sections 16A, 16B of e-bike controller 10A and seat post actuation device 10B to increase the distance between the two actuation devices 10A, 10B.

[0062] Fig. Figure 12 shows a bicycle 150 in the form of a mountain bike with an electric auxiliary motor EM and a bicycle actuation system 100 according to an embodiment of the present invention.

[0063] This bicycle 150 comprises, in a manner known per se, a front wheel 152, a rear wheel 154, and a frame 156. The front wheel 152 is rotatably mounted at the lower ends of a sprung front fork 158, which is rotatably held at its upper end on the frame 156 and carries a handlebar L for steering the bicycle 150. The rear wheel 154 is rotatably mounted about a wheel axle Z on a sprung rear swingarm 151, the suspension of which is adjustable via a damper unit 149. A front disc brake 131 and a rear disc brake 133 are provided for braking.

[0064] Unless otherwise stated, terms such as "front", "back", "top" and "bottom" refer to a bicycle 150 in its usual operating position with forward direction V, as shown in Fig. 12 are given.

[0065] The frame 156 also carries a saddle 252 on an electronically adjustable seat post 148 and a crank assembly with crank arms 254 and a front chainring 256 attached to them.

[0066] The crank assembly is rotatably mounted on the frame 156 around a bottom bracket axle 258. A rear sprocket set 130 (cassette) is mounted concentrically to the wheel axle Z on the rear wheel 154, which carries a plurality of sprockets of different diameters, i.e. with different numbers of teeth, while the front chainring 256 can be designed as a single wheel.

[0067] A rear derailleur system with a rear derailleur 132, also mounted at the rear of the frame 156, is used to adjust the gear ratios of the rear sprocket cluster 130. A chain 134 runs around the sprocket cluster 130 and the front chainring 256, passing through the derailleur 132 to transmit drive power from the crank arms 254 and the front chainring 256 to the sprocket cluster 130 and thus to the rear wheel 154. The derailleur 132 serves to adjust the chain 134 axially with respect to the axis of rotation Z of the rear wheel 154, in order to align the chain 134 with one of the sprockets of the sprocket cluster 130 and guide it accordingly onto the selected sprocket. The derailleur 132 can, in particular, include a front derailleur 137 that is adjustable via an electric motor, i.e., it can be electronically controlled.

[0068] The bicycle actuation device 100 according to the invention Fig. 12 comprises an actuation unit 10 in the form of an e-bike controller 10A for controlling various functions and settings of the electric auxiliary motor EM. The transmission of control commands can be wireless via a radio link between a radio transmitter, preferably integrated in the bicycle actuation unit 10A, and a radio receiver integrated in or on the auxiliary motor EM.

[0069] Furthermore, the bicycle operating device comprises 100 in Fig. 12 also includes an actuating unit 10 or 10B for adjusting the seat post 148. The actuating devices 10A, 10B are in Fig. 12 are only shown schematically, but can be designed, for example, as in Fig. 11 illustrated.

[0070] The type of bicycle actuation devices 10 shown in the figures is chosen only as an example, and the invention may relate to actuation devices for any bicycle components which can be controlled mechanically and / or electronically and / or hydraulically, for example the rear derailleur 132 or the damper unit 149 for the rear swingarm 151 or a damper unit for the front fork 158.

[0071] The control can be wired or wireless, and hybrid forms are also possible. In the example shown, the control of the controller assigned to actuating device 10A is, for instance, electronically wireless, and the control of the seat post 148 assigned to actuating device 10B is mechanical.

[0072] In many cases, the actuating elements are designed as switches, levers, push buttons, or rotary knobs and are thus movably mounted on the main body of the respective actuating device. However, this is not necessarily the case, for example, when a touchscreen is provided as the actuating element. Thus, an actuating device according to the invention can also be used to operate, for example, a bicycle computer located in the center of the handlebars.

[0073] Overall, the present invention proposes a bicycle actuation system that enables the flexible and space-saving attachment of several stacked actuation devices to the same circumferential position of a handlebar clamp using a single fastening means.

[0074] In particular, the fastening sections or interfaces of the various components can be coordinated in such a way that the number and order of the stacked components are variable.

[0075] The bicycle actuation device according to the invention, with its mounting section projecting from the main body and the through-opening formed therein as a mounting opening that connects opposing mounting surfaces, is specifically designed for use in such a system.
