Description

[0001] The invention relates to a bicycle damper, in particular a bicycle seat post damper for reducing the impact of a bicycle saddle mounting device, such as a seat post, relative to a bicycle frame, or a bicycle handlebar damper for reducing the impact of a bicycle handlebar mounting device, such as a stem, relative to the bicycle frame, or a bicycle frame damper for reducing the impact of a bicycle frame relative to a wheel mounting device, in particular a front or rear wheel. Furthermore, the invention relates to a bicycle adapter for arranging and / or aligning attachments on bicycles. Furthermore, the invention relates to a bicycle with such a bicycle damper and / or with such a bicycle adapter.

[0002] Such bicycle dampers are known in various variants. In particular, dampers are known which enable comfort through a spring-acting and / or particularly flexible material in the respective frame support, in particular the seat post. In addition, mechanical damping systems are known, as is also the case with the present invention. Such dampers are usually arranged below the saddle or below a saddle attachment, on or in a substantially vertically oriented seat post tube supporting the saddle and connected to the bicycle frame, or on or in a substantially horizontally oriented handlebar stem supporting the handlebars and connected to the bicycle frame, or on a seat stay arranged between the saddle and the rear wheel, or on a fork support arranged between the handlebars and the front wheel.They are used in particular to absorb shocks that are transmitted from the front or rear wheel through the frame to the saddle or handlebars, where they can affect the rider's buttocks or hands.

[0003] Such damping devices generally comprise a distal first frame part, also called the lower tube section, facing the bicycle frame, and a distal second frame part, also called the upper tube section, facing away from the bicycle frame and facing the receiving device, in particular - depending on the arrangement - the bicycle saddle or handlebars. The first frame part and the second frame part can be connected to one another exclusively by the damping device. The damping device is thus generally an intermediate member arranged between the bicycle frame and the seat post or handlebars or other distal component of the bicycle frame, which is nowadays designed exclusively to achieve its purpose, namely to provide an effective spring effect. For this purpose, such a damping device typically requires the entire installation space between the aforementioned first and second frame parts.

[0004] Given this, however, components that are intended to pass through the section of the damping device used as an intermediate piece must regularly be routed laterally past it. Such components include Bowden cables, wires, electrical cables, and other devices. However, routing these components laterally creates undesirable aerodynamic drag on the bike and makes it less visually appealing.

[0005] With this in mind, such dampers are often positioned in such a way that they do not interfere with the guidance of the aforementioned components. However, this can lead to further disadvantages, such as an unfavorable arrangement of the damping device or the component in question.

[0006] If components such as an electrical cable are routed past and a rear light is arranged under a seat post, for example, a further problem arises in the positioning of such a rear light. Such rear lights are usually arranged on the seat post. However, seat posts are usually aligned at an angle to the vertical in their longitudinal extent. In other words, seat posts are usually aligned at an angle to the vertical in their longitudinal extent. This often means that rear lights, when mounted on a seat post, must be aligned essentially horizontally in terms of their beam angle towards the rear of the bicycle. This is usually done using a lever arm, which can be pivoted and thus aligned either relative to the seat post or relative to the rear light.However, it has been shown that vibrations while riding a bike or other environmental influences can regularly cause the alignment of the rear light to change, thus compromising a correct and safe beam angle. Similar disadvantages can arise with front lights mounted on the handlebars.

[0007] The object of the present invention is therefore to provide a bicycle damper which improves at least one of the above-mentioned disadvantages and in particular enables a safe and visually appealing routing of additional components, in particular electrical cables, as well as a permanently stable, and thus safe, and aerodynamically advantageous alignment of rear lights.

[0008] The invention solves the stated problem by a bicycle damper having the features of the main claim, by a bicycle adapter having the features according to claim 20 and by a bicycle having the features according to claim 38. Advantageous embodiments and further developments of the invention are disclosed in the subclaims, the description and the figures.

[0009] According to the invention, the damping device has at least one cable feedthrough for arranging an electrical cable. This allows an electrical cable to be routed through the damping device, which is arranged in particular on a seat post. The cable or the cable guide can be fully integrated into the damping device. In particular, the cable does not have to be routed laterally past the damping device. The cable can thus also be protected by the damping device, for example, against unintentional contact by the rider or other environmental influences. This enables secure and visually appealing cable routing in the section of the damping device.

[0010] The cable guide can be used in particular to guide the electrical cable. The electrical cable can be a cable for power supply or data transmission. The electrical cable can be guided through the shock absorber of the bicycle in a particularly clever way. In the example of a seat shock absorber, the electrical cable can, for example, be a connection between a power source arranged on the bicycle and an additional component, in particular an add-on part, which requires electrical voltage. For example, the electrical cable from a bicycle battery or a bicycle dynamo can be guided through the seat post shock absorber into an area below a saddle surface. In this area, for example, an electrical add-on part such as a GPS tracker or a light can be arranged. Alternatively, the electrical cable can be guided to a differently arranged component.This mostly depends on the location of the damper and / or the mounting device.

[0011] In this case, the mounting device is understood to mean, in particular, a component by means of which another component, such as a saddle, handlebars, or wheel, can be attached or mounted to the frame. Particularly in the case of a rotating wheel, this can also be a bearing-type attachment.

[0012] Since the present invention is fundamentally suitable for damping a saddle relative to the bicycle frame and, alternatively, for damping a handlebar relative to the bicycle frame and, alternatively, for damping a bicycle frame relative to a wheel mount, it should be clear that the term bicycle damper in the present case refers to a damper in a substantially vertically oriented seat post supporting the saddle, or a damper in a substantially vertically oriented handlebar post supporting the handlebar, or a damper in a frame part, such as a rear wheel stay or a front wheel fork. For the sake of clarity, the supporting component that comprises the first frame part and the second frame part, or for which the bicycle damper is intended, or in which the bicycle damper is mounted, will hereinafter also be referred to simply as the support.This includes in particular the seat post, the handlebar stem, the rear wheel stay and the front wheel stay or fork.

[0013] In a first embodiment of the invention, it is provided that the cable feedthrough extends from the first frame part, in particular from a side of the first frame part facing the bicycle frame, through the damping device, in particular centrally through the damping device, into the second frame part - usually arranged above the first frame part - in particular up to a side of the second frame part facing the receiving device. As a result, a cable which is guided inside a bicycle frame, in particular of the first frame part, can be guided directly into the damping device at an end axial to the damping device, in particular without being visible from the outside. Furthermore, the cable can be guided through the damping device without being visible from the outside.Furthermore, the cable from the damping device can be routed directly into the second frame part at an end axial to the damping device, in particular without being visible from the outside. The entire cable routing on the damping device can thus be designed to be invisible from the outside, enabling not only secure cable routing but also a particularly attractive appearance.

[0014] In an alternative second embodiment of the invention, it is provided that the cable feedthrough extends exclusively from the first frame part, in particular from a side of the first frame part facing the bicycle frame, or from the second frame part, in particular from a side of the second frame part facing the receiving device, into the damping device and extends laterally out of the damping device substantially centrally of the distance between the first frame part and the second frame part, in particular toward the rear of the bicycle. This advantageously allows the cable to be routed to any desired position, in particular to any desired position on the damping device.For example, the cable which is routed inside a bicycle frame, in particular of the first frame part, can be routed directly into the damping device at an end axial to the damping device, in particular without being visible from the outside. Furthermore, the cable can be routed through the damping device without being visible from the outside. Furthermore, the cable can be routed out of the damping device again at a desired side of the damping device, which in particular does not represent the end facing the second frame part, for example in order to be able to be connected to a light, a plug or another bicycle component in this area. The entire cable routing on the damping device can thus again be designed so that it is not visible from the outside, thus enabling not only secure cable routing but also a particularly attractive appearance.

[0015] The damping device preferably has at least two lever arms arranged at an angle to one another, which connect the first frame part to the second frame part. The first frame part and the second frame part can in particular be connected to one another exclusively by the at least two lever arms. The lever arms can each be mounted in an articulated, in particular pivotable, manner on the first frame part and on the second frame part. The articulated connection to the frame parts can in particular be effected by means of a bolt connection or screw connection. For this purpose, the lever arms preferably each have four individual plain bearings. Advantageously, the lever arms are not arranged parallel to one another. Furthermore, the lever arms are preferably not of the same length.The two lever arms are therefore advantageously designed to be different lengths; in particular, the lever arm facing the bicycle frame can be longer than the lever arm facing away from the bicycle frame. This arrangement makes it possible to achieve a particularly linear damping effect between the first frame part and the second frame part, so that the rider does not experience any forward or backward displacement and, in particular, no twisting of the hands when the damped components dip. In particular, damping can be achieved with a very small offset by actively rotating the second frame part in order to compensate for the flexible bending or twisting that usually occurs towards the rear of the bicycle due to the flexibility of the material. Furthermore, a rotational movement of the saddle can be compensated.A lever arm is therefore to be understood in particular as a beam or strut which is articulated at its two distal ends, in this case on the first and second frame part. The non-parallel arrangement advantageously makes it possible to move the first frame part relative to the second frame part in a substantially rectilinear trajectory when the lever arms are pivoted, in particular without a significant offset in the direction of the longitudinal extent of the lever arms. The lever arms define in particular a distance or gap between the two frame parts and guide the latter two towards each other in the event of an impact and the resulting immersion of the damper system. This enables particularly comfortable driving.Optionally, the bicycle support, like the seat post, can be constructed from a flexible material, particularly in the areas of the frame parts, thus enabling an additional spring effect for particularly high levels of comfort. The cable routing preferably extends to the sides of the lever arms, particularly inside the damping device. This allows for safe and protected cable routing even with this type of damping device. Furthermore, the design of the damping device enables particularly effective and visually appealing "suspension" of the second frame part and a bicycle component arranged on it, such as a saddle.

[0016] If the damping device is designed such that the lever arms are each formed in two parts and each lever arm pair is formed with a first arm part and a second arm part, the cable guide preferably extends substantially centrally through at least one of the lever arm pairs. In particular, the cable feedthrough can extend through both lever pair arms, in particular centrally through both lever arm pairs. This design is advantageous if the electrical cable is to be arranged between the first and second frame parts. Alternatively, the cable feedthrough can extend centrally through at least the lever arm pair facing the first frame part. Furthermore, in this case the electrical cable can be guided out of the damping device between a first lever arm pair and a second lever arm pair.This embodiment is particularly advantageous if the cable feedthrough in the damping device is provided between the first frame part and an outlet of the damping device on the side of the damping device, as explained above in relation to a second embodiment of the invention.

[0017] In a preferred embodiment of the invention, the damping device is designed without a spring. This means that the damping device does not include a spring to absorb a shock. This allows the damping device to be particularly lightweight and space-saving, requiring particularly little installation space. Furthermore, a particularly safe and low-maintenance damping device is possible. Furthermore, compared to conventional dampers with springs, there is a lower risk of injury. The cable can be routed through the center of the damping device. This allows for a particularly protected cable feedthrough even with springless damping systems.

[0018] The damping device can be designed such that it continues the outer contour of the first and second frame part, in particular without the outer contour of the frame parts protruding. This enables a particularly low flow resistance in the area of ​​the support. Furthermore, a visually particularly appealing appearance of the support is possible, in particular without the damping device changing the external appearance. For this purpose, the damping device can be arranged completely internally, in particular such that the damping device is designed such that it does not protrude from the adjacent longitudinal outer contour of at least one of the first or second frame part, so that the device does not change the outer contour of the entire tube. At least visually, the damping device thus appears to be completely integrated into the support.This results in a comparatively low risk of injury and a visually appealing appearance.

[0019] Preferably, the first frame part and the second frame part are arranged to overlap one another at least partially along their longitudinal extent, in particular in a respective distal end section of the frame parts. In particular, the frame parts can be arranged parallel to one another, spaced apart by a respective longitudinal section, in particular without being in direct contact with one another. As a result, the size and shape of the outer contours can remain at least virtually unchanged even when the support is submerged, and in particular do not protrude significantly beyond the outer contours of the frame parts. This is particularly advantageous in terms of flow resistance. Further advantages arise with regard to a particularly visually appealing appearance of the bicycle support.

[0020] In a preferred embodiment of the invention, the damping device additionally comprises a deformable elastomer part. In this case, the cable feedthrough can extend through the elastomer part. In particular, the cable feedthrough can extend centrally through the elastomer part between the first frame part and the second frame part or between the first frame part and a lateral outlet of the damping device. The outlet of the damping device can be an outlet of the cable feedthrough on the elastomer part. The elastomer part can extend in the longitudinal extent of the bicycle support at least over the section of the damping device. In this case, the elastomer part is to be understood in particular as a deformable, elastic component. The elastomer part serves in this case as a damping element, in particular for braking, guiding and limiting a movement of the lever arms relative to the first and / or second frame part.It can be provided that the damping effect can be adjusted by selecting the elastomer material, in particular a hard or soft elastomer part.

[0021] In particular, if the damping device comprises a first lever arm and a second lever arm, wherein the lever arms connect the first frame part to the second frame part and are pivotally mounted on the first frame part and the second frame part, respectively, the deformable elastomer part, which has the cable feedthrough, can be arranged between the two lever arms. This enables a particularly aerodynamically advantageous design and a particularly visually appealing appearance of the damping device.

[0022] Particularly preferably, the elastomer part has a recess for the cable feedthrough. This recess can be designed, for example, as a channel. An electrical cable or a guide element containing the cable, such as a hose, can be inserted into this channel.

[0023] Additionally, the elastomer part can have further recesses. For example, the elastomer part can have at least one recess through which at least one of the lever arms extends. Preferably, the elastomer part has two recesses, with a lever arm extending through each of the recesses. The recess in the elastomer part is advantageously arranged centrally in the elastomer part, in particular such that the lever arm extending through it is completely surrounded on its circumference by the elastomer part material. The cable duct can cross this recess or, alternatively, be guided past the lever arm in a lateral region within the elastomer part. Particularly preferably, the lever arm is mounted and guided within the recess of the elastomer part.This enables, on the one hand, particularly safe operation of the damping device and, on the other hand, a particularly space-saving design, so that the damping device as a whole is suitable for being particularly streamlined and thus enables particularly low flow resistance.

[0024] Preferably, the elastomer part with the recess and the lever arm extending therethrough are arranged relative to one another in such a way that the lever arm forms a connecting part, which is connected to the frame parts at the two distal ends and extends with a central part through the recess. This enables particularly effective guidance of the first frame part relative to the second frame part during a damping process, thus enabling particularly reliable operation of the damping device. Particularly preferably, the lever arm and the elastomer part are arranged so as to be non-contact with one another.

[0025] Particularly preferably, the elastomer part is arranged in a form-fitting manner between the first frame part and the second frame part. In particular, the elastomer part can be adapted to the end edge of the respective frame part with a distal, circumferential end edge, so that these are configured to correspond to one another and form a form-fitting end edge. This enables a particularly flush transition between the elastomer part and the frame part, so that the damping device has particularly low flow resistance. This results in a comparatively low risk of injury, and the system is optimally protected against the accumulation of dirt.

[0026] The elastomer part is preferably S-shaped, with the upper part of the S resting against the second frame part and the lower part resting against the first frame part, and the lever arms being guided through the elastomer part in the middle part. In the middle part, the elastomer part preferably has outer sides which are preferably arranged parallel to the longitudinal extent of the bicycle support tube. In this middle region, the two frame parts can be spaced apart and arranged essentially parallel to one another. This enables a particularly compact design of the damping device. Alternatively, the two frame parts can be spaced apart and arranged at a slight angle to one another. This configuration is particularly advantageous for precisely matching the frame parts to a desired curve during a damping process.

[0027] Preferably, the lever arms and the elastomer part are arranged in such a way that, when loaded, the elastomer part is compressed in a guided manner, thereby displacing the two frame parts relative to one another essentially exclusively in the direction of their longitudinal extent. In addition to compression, in one variant of the invention, twisting can also occur in order to compensate for bending, for example due to a flexible seat post material, and the associated rearward twisting. An offset of the saddle towards the rear of the bicycle can be compensated for or reduced, in particular, by the "compression" of the elastomer towards the front of the bicycle, so that the horizontal distance (perpendicular to the longitudinal extent of the seat post) in the vertical gap between the two frame parts can be kept almost the same, while the vertical distance (in the longitudinal extent of the seat post) between the two frame parts is reduced.Such an arrangement can be achieved in particular by a predefined angle between the two lever arms. In particular, the non-parallel arrangement and a preferably non-equal length of the two lever arms enable the two frame parts to be guided essentially in a straight line relative to one another during shock absorption, in particular in the direction of the longitudinal extension of the seat post. The term "essentially" in this context means that the two frame parts are only slightly offset and twisted. In particular, a large lateral offset or a large lateral displacement or twisting of the first frame part relative to the second frame part, in particular towards the front or rear of the bicycle, can be effectively prevented.For example, due to the combination of material flex of the saddle and counter-rotation of the frame parts, the rider of the bike essentially experiences no change in the direction of the front or rear of the bike when the shock absorbs.

[0028] Preferably, the receiving device comprises a fastening means for attaching a saddle, handlebar, or wheel. The fastening means defines an axis along its longitudinal extent, and the lever arms and the elastomer part are arranged such that, upon impact, the axis is displaced exclusively in the direction of the longitudinal extent of the support, in particular the seat post or the handlebar tube or the wheel stay, and in particular not laterally offset therefrom. The fastening means can, for example, be a fastening screw arranged in a direction transverse to the straight-ahead direction of the bicycle.

[0029] Preferably, the lever arms are each designed separately and arranged such that the lever arms are replaceable independently of the mounted elastomer part and independently of the mounted frame parts. In particular, the lever arm can be disassembled and assembled for replacement without the elastomer part and / or the frame parts needing to be removed. Removal takes place in particular in the direction of the longitudinal extent of the lever arm. This enables particularly uncomplicated replacement. The lever arm, with its two distal ends, can form part of the outer contour of the support that is visible from the outside. This enables visual inspection of the lever arm without major effort, in particular without disassembling components.

[0030] Particularly preferably, the lever arms are each arranged in their longitudinal extension substantially perpendicular to the longitudinal direction of the support, in particular the seat post or the handlebar tube, in particular at an angle to the longitudinal direction of the support of between 70 and 90 degrees. This effectively minimizes any lateral offset or displacement of the first frame part relative to the second frame part, in particular toward the front or rear of the bicycle.

[0031] According to the invention, the bicycle adapter for arranging and / or aligning attachments on bicycles comprises an adapter body with at least one first side surface and with a second side surface oriented at an angle to the first side surface, wherein the adapter body is designed to be mounted on the bicycle with at least the first side surface in two different positions, in particular rotated by 180 degrees, in particular with first coupling means for coupling the adapter body to the bicycle. For this purpose, the first side surface can preferably have first coupling means for coupling the adapter body to the bicycle, in particular on or with a fastening device provided on the bicycle. This enables a particularly suitable arrangement and alignment of an attachment on a bicycle. It should be clear that an attachment is understood to mean any additional component for a bicycle.Such additional components can in particular be separately formed units that can be mounted on a bicycle, such as a rear light or a bag. The first side surface is in particular aligned obliquely to the second side surface. In particular, the first side surface can be arranged at an angle of between 8 degrees and 40 degrees to the second side surface, particularly preferably at an angle of approximately 30 degrees. The side surfaces can in this case be formed on the adapter body as flat, in particular planar, side walls. The first coupling means can be conventional means for connecting the adapter body to the bicycle, for example a frictional connection means, such as a fastening screw, a form-fitting connection means, such as a rail, slide and / or locking lug device.Such first coupling means can, for example, be through-holes provided on the adapter body, through which a fastening screw can extend to fix the adapter body to the bicycle, in particular to the fastening device. The through-hole is advantageously arranged corresponding to a threaded hole arranged on the bicycle or on the fastening device, so that a fastening screw extending through the through-hole formed on the adapter body can further extend into the corresponding threaded hole in the fastening device arranged on the bicycle. The fastening device can be a component of the bicycle, in particular of the bicycle frame, or of an additional device, such as the aforementioned bicycle shock absorber.It is particularly advantageous if at least two through-holes are formed on the first side of the adapter body and these through-holes are arranged symmetrically with respect to a central transverse axis, such that the adapter body can be mounted on the bicycle particularly easily rotated by 180°. Particularly preferably, the adapter body adjoins the fastening device on the side of the first side in a corresponding manner, such that there is no offset between the side walls of the adapter body and the fastening device. This enables particularly advantageous aerodynamics as well as a visually particularly appealing appearance. The fact that the adapter body of the fastening device does not protrude laterally can be the case in particular in both mounting positions - rotated by 180°.

[0032] In principle, the attachment can be designed as an integral component of the adapter body. Alternatively, the adapter body has second coupling means on the second side surface for coupling to the attachment. In particular, two or more attachments can also be provided; for example, a first attachment can be integrated into the adapter body, and a second attachment can be located externally on the adapter part, in particular on its second side surface. This enables a particularly comprehensive and compact unit.

[0033] The adapter body is preferably designed as a solid body. Particularly preferably, the adapter body is substantially triangular, in particular substantially as a triangular prism, in particular as a right-angled triangle or as a right-angled triangular prism, or also called a three-sided right-angled prism. It has been shown that such a configuration of the adapter body is a particularly suitable shape for the task and function of the adapter. Thus, bicycle frame parts, such as a seat post, can be used in their orientation relative to a vertical plane, making particularly effective use of the space and aerodynamic conditions.

[0034] Preferably, the first side surface is formed by a side forming a leg of the triangle, in particular an adjacent side of the triangle, and the second side surface is formed by a side forming a hypotenuse of the triangle. It has been shown that with such a configuration, particularly when used on a seat post, the orientation of the adapter body and an attachment arranged thereon, such as a rear light, can be aligned particularly precisely. It is therefore particularly advantageous if the adapter body can be mounted on the bicycle rotated by 180°, in particular either with the hypotenuse adjacent to the first side at the bottom of the bicycle or adjacent to the fastening device or at the top. This allows the angle of the second side and of an attachment arranged thereon to be changed in relation to the bicycle frame in a particularly simple manner.

[0035] In a further development of the invention, it may also be provided that the adapter body is designed such that the adapter body can be mounted on the bicycle either with the first side surface or with the second side surface. For this purpose, second coupling means can be provided on the second side surface. This allows for a flexible arrangement of the adapter body on the bicycle.

[0036] Preferably, the coupling means for coupling the adapter body to the bicycle are part of a respective fastening system. In particular, the coupling means can belong to a system of mutually corresponding connecting elements, for example, male and female connector solutions, a wheel-rail system, and / or a locking device. The fastening system can, in particular, also comprise the above-mentioned fastening device on the bicycle.

[0037] Preferably, a first fastening system comprises the first coupling means arranged on the adapter body and first counter-coupling means on the bicycle corresponding to the first means for fastening them together, and / or a second fastening system comprises the second coupling means arranged on the adapter body and second counter-coupling means on an attachment part corresponding to the second coupling means for fastening them together. This allows for the use of individually tailored fastening systems, so that the arrangement and alignment of the attachment part can be particularly precise and secure.

[0038] Preferably, the first fastening system is designed such that the adapter body can be coupled to the bicycle, in particular to the first counter-coupling means, with the first side surface in two positions, in particular rotated by 180°. In particular, the first coupling means can be designed such that, for fastening the adapter part to the bicycle, they can be coupled, in particular to the first counter-coupling means arranged on a fastening device, either in a first position or in an arrangement rotated by 180 degrees. In combination with the geometric design of the adapter part, the orientation of the attachment part with respect to the bicycle can be adapted and changed in a particularly simple manner.

[0039] It can also be provided that the second fastening system is designed such that the attachment, in particular with the second counter-coupling means, can be coupled to the second side surface of the adapter body in two positions, in particular rotated by 180 degrees. In particular, the second coupling means can be designed such that, for fastening the attachment to the adapter part, they can be coupled to the second counter-coupling means either in a first position or in an arrangement rotated by 180 degrees. In combination with the geometric design of the adapter part, the orientation of the attachment with respect to the bicycle can be adapted and changed in a particularly simple manner.

[0040] Preferably, the first coupling means and the second coupling means are of identical design, in particular each as a fastening screw. This allows the adapter body to be attached to the bicycle in a different arrangement, for example, with the second side or with the second coupling means on the first counter-coupling means.

[0041] For this purpose, the first counter-coupling means and the second counter-coupling means are preferably designed identically, in particular each as a threaded bore. This allows the adapter body to be mounted particularly easily.

[0042] Preferably, in a coupled state, a positive and / or non-positive connection is established between the coupling means and the counter-coupling means. This allows the adapter body to be mounted particularly easily.

[0043] In one embodiment of the invention, the first counter-coupling means is arranged on a bicycle damper, in particular on a bicycle damper having the features according to one of claims 1 to 18.

[0044] Preferably, in a coupled state, an electrical voltage can be transmitted between the attachment and the adapter body and / or between the adapter body and the bicycle, in particular between the coupling means and a respective counter-coupling means. For example, an electrical voltage or an electrical current drawn from a battery provided on the bicycle can be conducted to the attachment via the adapter body, in particular in the form of a cable. This enables the use of a bicycle battery for an attachment.

[0045] Preferably, at least the coupling means and the counter-coupling means have a mutually corresponding interface for transmitting electrical voltage. This enables a particularly simple and reliable transmission of electrical voltage. Furthermore, the electrical voltage can be applied with various arrangements of the adapter body.

[0046] Preferably, the adapter body has a housing that at least partially surrounds the attachment. Particularly if the attachment is integrated into the adapter body, such as a taillight, the housing of the adapter body can at least partially surround the attachment. This allows the attachment to be designed particularly compactly.

[0047] Preferably, the adapter body and / or the attachment comprises electronics. In particular, the attachment can be designed as an electronic component, such as a taillight. The attachment can thus be used for various purposes.

[0048] Particularly preferably, the adapter body and / or the attachment has at least one mudguard, a bag, such as a lock or tool bag, a bottle holder, a light, such as a rear light, a GPS transmitter, in particular a tracker, a battery, in particular an accumulator, a charging socket, such as a USB port, and / or a rear view camera or is designed as such.

[0049] According to the invention, a bicycle is provided with a bicycle damper having the features according to one of claims 1 to 19 and / or with a bicycle adapter having the features according to one of claims 20 to 37.

[0051] In the Fig. 1a, reference numeral 100 shows a first example of a bicycle according to the invention with a bicycle frame 10 and a bicycle damper 1 according to the invention.

[0052] The bicycle damper 1 is presently arranged on a bicycle seat post 16 and is accordingly designed as a bicycle seat post damper 1' for reducing the impact of a saddle mounting device 13 relative to the bicycle frame 10. For this purpose, the bicycle damper 1 has a damping device 2.

[0053] In the Fig. Figure 1b shows the bicycle damper 1, 1' according to the invention with a damping device 2 in detail. The bicycle saddle damper 1, 1' serves to reduce a shock acting on a saddle (not shown here), in particular to reduce the shock of a bicycle saddle mounting device 13 relative to the bicycle frame 10 (not shown in detail here).

[0054] A seat post tube 16 extends essentially vertically from the bicycle frame 10 (not shown in detail here). The seat post tube 16 has a conventional fastening device 13 at its upper end for mounting a saddle (not shown). The seat post tube 16 is formed in at least two parts. In particular, the seat post tube 16 comprises a first frame part 11, also called the lower tube section, which faces the bicycle frame 10 (not shown in detail here), and a second frame part 12, also called the upper tube section, which faces away from the bicycle frame 10 (not shown in detail here) and faces the saddle mounting device 13. A saddle (not shown here) can be mounted on the saddle mounting device 13.

[0055] In this case, the first frame part 11 and the second frame part 12 are each formed, at least in a main section, as an oval tube in cross-section. It should be clear that the frame parts 11, 12 can of course also be formed as round tubes. The first frame part 11 is connected, in particular detachably connected, to the bicycle frame 10 (not shown in detail).

[0056] The first frame part 11 and the second frame part 12 have a substantially identical outer contour 14 and are arranged parallel or overlapping to one another over a portion of their longitudinal extent (axial direction R1), in particular in a respective distal end section 15, 15'. However, the frame parts 11, 12 are not in contact, but rather are arranged at a distance from one another. The end-to-end distance (in the axial direction) is approximately twice the transverse distance between the two frame parts 11 and 12. In the aforementioned region, the two frame parts 11, 12 are connected to one another by a damping device 2.

[0057] In the Fig. 2 to 4, in addition to the functionality of the damping device 2, two different embodiments of a cable bushing are shown in more detail. Fig. 2 a first embodiment of the cable guide 30 and in the Fig. 3a, Fig. 3b and Fig. 4 shows a second embodiment of the cable guide 30. Furthermore, Fig. 3a a saddle receiving device 13 adjacent to the second frame part 12 in a non-submerged state 101, while in Fig. 3b shows a submerged state 102 of this saddle support device 13. This allows shocks to the saddle to be reduced and dampened particularly effectively. Fig. 3a and Fig. For a better overview, an elastomer part 4 is not shown in Figure 3b.

[0058] For this purpose, the damping device 2 has two lever arms 3a, 3b, which connect the first frame part 11 to the second frame part 12. The lever arms 3a, 3b are each arranged in their longitudinal extent substantially transversely to a longitudinal direction R1 of the seat post 16. The lever arms 3a, 3b are arranged in their longitudinal extent at an angle to one another, in particular non-parallel to one another, in particular at an angle to the longitudinal direction R1 of the seat post 16 of between 70 and 90 degrees. The lever arms 3a, 3b are designed to have different lengths in the present case; in particular, the lever arm 3a facing the bicycle frame 10 or the first frame part 11 has a greater length than the lever arm 3b facing away from the bicycle frame 10 or facing the second frame part. Furthermore, the lever arms 3a, 3b are each mounted in an articulated, i.e. pivotable, manner on the first frame part 11 and on the second frame part 12.The articulated connection of the lever arms 3a, 3b to the frame parts 11, 12 can be achieved, in particular, by means of a bolt connection. For this purpose, a total of four plain bearings are provided for each lever arm 3a, 3b, two of which, 8, 8', are shown in the figures, so that the lever arms 3a, 3b can swing freely.

[0059] In the present case, the lever arms 3a, 3b are each formed separately and, in particular, arranged such that they are interchangeable independently of the mounted frame parts 11, 12. For this purpose, recesses are provided in the first frame part 11 and the second frame part 12, through which the lever arms can extend with a frontal region, in particular when the second frame part 12 is immersed particularly deeply relative to the first frame part 11. This enables disassembly and assembly of a lever arm 3a, 3b through the recess in the respective frame part 11, 12. Furthermore, an easy visual inspection of the lever arm 3a, 3b is possible.

[0060] According to the present invention, it is provided that the damping device 2 has at least one cable feedthrough 30 for arranging an electrical cable 31.

[0061] In the Fig. Figure 2 shows a first embodiment of the cable feedthrough 30 through the bicycle shock absorber 1. The cable feedthrough 30 extends from the interior of the first frame part 11, in particular from a side of the first frame part 11 facing the bicycle frame 10, through the damping device 2, in particular centrally through both lever arms 3a, 3b, into the interior of the second frame part 12, in particular to a side of the second frame part 12 facing the receiving device 13. The electrical cable 31 routed through the cable feedthrough 30 serves an electrical component arranged below the saddle surface (not shown), such as a GPS tracker or a seat heater. In order to guide the electrical cable 31 past the two lever arm pairs 3a, 3b, at least one of the two lever arms of a lever arm pair has a bend 15, which creates a semicircular recess in the transverse direction, through which the cable 31 is guided.

[0062] In the Fig. 3a, Fig. 3b and Fig. 4 shows an alternative example in which the cable duct 30 extends from the interior of the first frame part 11, in particular from a side of the first frame part 11 facing the bicycle frame 10, through the damping device 2, in particular centrally through the lower lever arm 3a facing the first frame part 11. Approximately in the axial center of the damping device 2 or at half an axial distance between the first frame part 11 and the second frame part 12, the electrical cable 31 is led out of the damping device 2, in particular toward a rear or tail 100a of the bicycle 100.

[0063] The cable guide extends within the damping device 2, particularly laterally past the lever arm 3a. When configured with a pair of lever arms, the cable guide can extend substantially centrally through at least one of the lever arm pairs.

[0064] The damping device 2 has a deformable elastomer part 4, as shown in Fig. 4. In this case, the elastomer part 4 extends in the longitudinal extension of the seat post 16 (or in the case of handlebar damping in the longitudinal extension of a handlebar tube) at least over the section of the damping device 2 and thus defines this section.

[0065] The elastomer part 4 is to be understood as a deformable, elastic component, which serves as a damping element, in particular for braking and limiting a movement of the lever arms 3a, 3b relative to the first frame part 11 and / or the second frame part 12. As in Fig. 4, the elastomer part 4 is arranged in a form-fitting manner between the first frame part 11 and the second frame part 12, in particular in such a way that it does not protrude from the outer contour 14 of the two frame parts 11, 12.

[0066] As particularly in Fig. As shown in Figure 5, the elastomer part 4 is S-shaped in this case. The upper part 5 of the S-shaped elastomer part 4 rests against the second frame part 12, and the lower part 6 of the S-shaped elastomer part 4 rests against the first frame part 11. Two recesses 6a, 6b are formed in the central part 7 of the S-shaped elastomer part 4. The recesses 6a, 6b serve to pass through the lever arms 3a and 3b. A central web 9 is formed between the recesses 6a, 6b.

[0067] In the upper part 5, the elastomer part 4 has a first section 30a of the cable feedthrough 30. In the lower part 6, the elastomer part 4 has a second section 30b of the cable feedthrough 30. The two sections 30a and 30b are designed as recesses or holes through the elastomer 4. The electrical cable 31 can be guided through this recess. In the middle part 7 of the S-shaped elastomer part 4, the cable feedthrough 30 is "free", i.e., without guidance through the elastomer part 4. In this area, guidance is provided by the lever arms 3a, 3b, which can have a corresponding recess, as for example in the Fig. 3a, Fig. 3b and Fig. 4 can be seen at the first lever arm 3a.

[0068] When the lever arms 3a, 3b are passed through the recesses 6a, 6b of the elastomer 4, they are arranged relative to one another such that each lever arm 3a, 3b forms a guide element, which preferably does not rest against the elastomer part 4. At the distal ends, the lever arms 3a, 3b are each connected to the frame parts 11, 12 via a joint, shown here as plain bearings 8, 8'. The lever arms 3a, 3b, which are pivotably mounted relative to the frame parts 11, 12, are consequently guided relative to the elastomer part 4 by the shape and precision fit of the recesses 6a, 6b.

[0069] If an impact occurs on the seat post tube 16 or any other load is applied to the seat post tube 16, the two frame parts 11, 12 are displaced relative to each other primarily in the direction R1 of their longitudinal extension, in particular without a major lateral offset. However, it is intended that the occurring offset or a twist between the two frame parts compensates for a twist occurring elsewhere, namely at the flexible seat post in a different direction, so that the rider experiences a primarily vertical damping movement overall, not one towards the front or rear of the bicycle. To clarify the movement of the lever arms 3a, 3b, Fig. 3a and Fig. 3b shows a bicycle damper 1, 1' without the elastomer part 4, in particular in two differently immersed states of the frame parts 11, 12. When the damper is immersed, the cable bushing 30 or the electrical cable 31 are only minimally forced into a free space which is formed in particular in the center 7 of the bicycle damper 1.

[0070] When designing according to the Fig. 6a and Fig. 6b, the bicycle shock absorber 1 is provided as a damper for a rear wheel axle of a bicycle 100 with a bicycle frame 10. Accordingly, the bicycle shock absorber 1 is arranged in a rear wheel strut, which connects a rear wheel mount to the rest of the bicycle frame, particularly in the direction of a saddle. With this arrangement, a shock occurring at the rear wheel can be dampened particularly effectively.

[0071] The bicycle shock absorber 1 is essentially constructed in the same way as described above. In particular, the bicycle shock absorber 1 comprises a first frame part 11, which in this case forms an upper part of the rear wheel strut, and a second frame part 12, which in this case forms a lower part of the rear wheel strut facing the rear wheel. The damping device 2, which corresponds in design and function to that described above, is arranged between the first frame part 11 and the second frame part 12.

[0072] In the Fig. In Figure 7, reference numeral 50 shows a bicycle adapter according to the invention for arranging and / or aligning attachments 60 on a bicycle 100. The bicycle adapter 50 comprises an adapter body 51, which in this case is essentially triangular, in particular essentially as a triangular prism. In particular, the adapter body 51 is designed as a right-angled triangular prism.

[0073] The adapter body 51 has, in particular, a first side surface 51a and a second side surface 51b aligned at an angle to the first side surface 51a. The triangular surface defining the body is formed between the side surfaces 51a and 51b. It is provided that the adapter body 51 can be mounted on the bicycle 100 with the first side surface 51a optionally in a first orientation or in a second orientation rotated by 180°. In particular, the adapter body 51 can be mounted on the bicycle 100 with the first side surface 51a, as shown, for example, in the Fig. 8 and Fig. 9. The first side surface 51a forms an adjacent side of the triangle, while the second side surface 51b forms the hypotenuse of the triangle.

[0074] First coupling means 52a are provided for mounting the adapter body 51 with the first side surface 51a on the bicycle 100. In a very simple embodiment, the first coupling means can be conventional fastening screws. Preferably, such first coupling means 52a are provided which allow a quick, in particular tool-free, coupling of the adapter body 51 to the bicycle 100.

[0075] The Fig. 7, the attachment part 60 not shown can be fastened in particular to the second side surface 51b of the adapter body 51. Preferably, the attachment part 60 is either fastened to the second side surface 51b on the adapter body 51, in particular by means of second coupling means 52b, as shown in the Fig. 8 and Fig. 9, or it is formed as an integral component 60a of the adapter body 51, in particular on the second side surface 51b.

[0076] The coupling means 52a, 52b for coupling the adapter body 51 to the bicycle 100 or to the attachment 60 can be part of a respective fastening system 55a, 55b, such as a screw-threaded hole fastening or a quick-release fastener (not shown in detail). The fastening systems 55a, 55b can, in particular, be designed identically, as is the case here.

[0077] The first fastening system 55a comprises the first coupling means 52a arranged on the adapter body 51 and first counter-coupling means 53a on the bicycle 100 corresponding to the first coupling means 52a for fastening them together. The second fastening system 55b comprises the second coupling means 52b arranged on the adapter body 51 and second counter-coupling means 53b on the attachment part 60 corresponding to the second coupling means 52b for fastening them together. The counter-coupling means 53a, 53b are particularly shown in the Fig. 8 and Fig. 9 recognizable.

[0078] The first fastening system 55a is designed such that the adapter body 51 can be coupled to the first side surface 51a in two positions, in particular rotated by 180°, on the bicycle 100, in particular to the first counter-coupling means 53a. In particular, the first coupling means are designed such that, for fastening the adapter part to the bicycle, they can be coupled to the first counter-coupling means 53a either in a first position or in an arrangement rotated by 180°. In the present case, the first coupling means 52a are designed as Allen screws, which can engage in the first counter-coupling means 53a designed as a threaded bore for fastening.

[0079] The second fastening system 55b is designed such that the attachment 60, in particular with the second counter-coupling means 53b, can be coupled in two positions, in particular rotated by 180°, on the second side surface 51b of the adapter body 51. In particular, the second coupling means are designed such that, for fastening the attachment to the adapter part, they can be coupled to the second counter-coupling means 53b either in a first position or in an arrangement rotated by 180°. In the present case, the second coupling means 52b are designed as Allen screws, which can engage in the second counter-coupling means 53b designed as a threaded bore for fastening.

[0080] The first coupling means 52a and the second coupling means 52b are thus designed identically in this case, in particular each as a fastening screw. The first counter-coupling means 53a and the second counter-coupling means 53b are thus also designed identically, in particular each as a threaded bore. Thus, in a coupled state, a force-locking connection can be established between the coupling means 52a, 52b and the respective counter-coupling means 53a, 53b.

[0081] The Fig. 7 The attachment 60 not shown can basically be a mudguard, a bag, such as a lock or tool bag, a bottle holder, a light, such as a rear light, a GPS transmitter, in particular a tracker, a battery, in particular an accumulator, a charging socket, such as a USB port, and / or a rear view camera or can be designed as such.

[0082] In the Fig. Figure 8 shows a first example of an attachment 60 designed as a bicycle rear light 18 on a bicycle adapter 50. The bicycle adapter 50 is arranged on a seat post 16 of a bicycle 100, in particular directly below a saddle 17. The bicycle adapter 50 is shown in particular arranged in a section of a previously described bicycle shock absorber 1, and in this case primarily serves to align the bicycle rear light 18 with respect to the bicycle frame 10, in particular with respect to the seat post 16.

[0083] The rear light 18 is designed as an attached and integral component of the adapter body 51. The attachment 60 designed as the rear light 18 comprises electronics, in particular an electronic component of the rear light 18. The electronic components can comprise typical control components of a bicycle rear light, in particular LED technology. To supply voltage to the rear light 18, a battery installed on the bicycle is used as a power source. To transmit the electrical voltage from the battery to the rear light 18, the coupling means 52a, 52b and the counter-coupling means 53a, 53b are provided with a mutually corresponding interface for transmitting electrical voltage. This can be in the form of a plug or a current-conducting contact point, for example.As a result, electrical voltage can be transmitted in a coupled state between the bicycle 100, the adapter body 51 and the attachment 60.

[0084] Alternatively or additionally, it may be provided that an additional attachment 60' comprising an accumulator is integrated into the adapter body 51.

[0085] In this case, the electrical voltage required for the rear light 18 mentioned as an example can also come from this power source.

[0086] In the Fig. 9 shows a second example of an attachment 60 designed as a bottle holder 19 on a bicycle adapter 50. The bicycle adapter 50 is again arranged on the seat post 16 of the bicycle 100, in particular directly below the saddle 17. This time, however, the bicycle adapter 50 is in a Fig. 8 is attached to the bicycle in a 180 degree rotated arrangement. It should be clear that the Fig. 9 shown bicycle adapter 50 to the same bicycle adapter as in Fig. 8 shown, can act.

[0087] The bicycle adapter 50 is again shown in an arrangement in a section of a previously described bicycle shock absorber 1, and in this case serves primarily to align the bottle holder 19 with respect to the seat post 16. This arrangement allows the bottle to be easily removed from the holder 19 without being blocked by the saddle 17.

[0088] In the Fig. 10 shows an example of a bicycle 100 with a bicycle shock absorber 1, 1', in which a cable guide 30 extends through the entire shock absorber 1', as shown in detail in Fig. 2. The cable 31 extending from the bicycle frame 2, in particular from a power source mounted there, serves to supply voltage to an additional component 70 located below the saddle 17. The additional component 70 can be designed, for example, as a GPS tracker or as a rear light.

[0089] Furthermore, Fig. 10 shows how the damper 1' is configured without the previously described attachment 60 being arranged, in particular on a side facing the attachment 60 to be arranged. On this side, the first counter-coupling means 53a is arranged, which is designed to be fastened together in a manner corresponding to the first coupling means 52a of the attachment 60.

[0090] Since the above-described system of the bicycle shock absorber with cable feedthrough and the bicycle adapter is not only suitable for seat posts, it can also be applied to a handlebar post, rear wheel stay, front wheel fork, or any other frame component of a bicycle. It should therefore be clear that the scope of the present invention is not limited to the described embodiments. In particular, the structure of the component arranged on the second frame part—whether saddle or handlebar, frame, or fork—can be modified without altering the essence of the invention.
