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 with such a bicycle damper.

[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 typically 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 each other exclusively by the damping device.

[0004] It has been shown that with such dampers, when the damped components, especially a component in contact with the rider such as the saddle or handlebars, are submerged, in addition to the shock-absorbing effect, a lateral displacement of the damped component occurs, particularly forwards or backwards in the direction of travel of the bicycle. This is often accompanied by a slight twisting of the damped component. However, this can lead to an unwanted change in the distance between the upper body and the handlebars or to an unwanted twisting of the hands on the handlebars. Furthermore, most known damping systems are relatively bulky, usually also associated with a considerable weight.

[0005] The object of the present invention is to provide a bicycle damper which improves at least one of the above-mentioned disadvantages and in particular enables safe and comfortable damping with the lowest possible weight and low air resistance as well as a visually appealing appearance of the damper on the bicycle.

[0006] The invention solves the stated problem by a bicycle damper having the features of the main claim and by a bicycle according to claim 15. Advantageous embodiments and further developments of the invention are disclosed in the subclaims, the description and the figures.

[0007] According to the invention, the damping device has two lever arms which are arranged at an angle to one another, in particular not parallel to one another, and preferably not of the same length, and which are each articulated, i.e. pivotally mounted, on the first frame part and on the second frame part, which lever arms connect the first frame part to the second frame part. In this case, in particular the first frame part and the second frame part are articulated to one another by two lever arms which are arranged at an angle to one another, in particular not parallel to one another. The first frame part and the second frame part can in particular be connected to one another exclusively by the two lever arms. The articulated connection to the frame parts can in particular be achieved by means of a bolt connection or screw connection. For this purpose, the lever arms preferably each have four individual plain bearings.The two lever arms are 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. This enables particularly comfortable riding.Optionally, the bicycle support, like the seat post, can be constructed from a flexible material, particularly in the area of ​​the frame parts, so that an additional spring effect is possible for particularly high levels of comfort.

[0008] 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.

[0009] A lever arm, in this case, is understood to be a beam or strut that is articulated at its two distal ends, in this case on the first and second frame parts. The non-parallel arrangement 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 extension of the lever arms. The lever arms, in particular, define 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.

[0010] Since the present invention is suitable both 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 is understood here to mean 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, is also referred to below as the support.This includes in particular the seat post, the handlebar stem, the rear wheel stay and the front wheel stay or fork.

[0011] 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, there is a lower risk of injury compared to conventional dampers with springs.

[0012] In a further preferred embodiment of the invention, it is provided that the damping device 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 region 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 on the inside, in particular in such a way 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.

[0013] 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.

[0014] In a preferred embodiment of the invention, the damping device additionally comprises a deformable elastomer part. The elastomer part can extend in the longitudinal direction of the bicycle support at least over the section of the damping device. In this case, the elastomer part is understood to mean, in particular, a deformable, elastic component. The elastomer part serves 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 is adjustable by selecting the elastomer material, in particular a hard or soft elastomer part.

[0015] The elastomer part preferably has at least one recess through which at least one of the lever arms extends. More 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 the circumference by the elastomer part material. More preferably, the lever arm is mounted and guided within the recess of the elastomer part. This enables particularly reliable operation of the damping device on the one hand and a particularly space-saving design on the other, so that the damping device as a whole is suitable for a particularly streamlined design and thus enables particularly low flow resistance.

[0016] 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.

[0017] 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 designed 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.

[0018] 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. In the middle part, the lever arms are guided through the elastomer part. In the middle part, the elastomer part preferably has outer sides that are preferably arranged parallel to the longitudinal extension of the bicycle support tube. In this middle region, the two frame parts can be arranged parallel to each other, spaced apart. This enables a particularly compact design of the damping device.

[0019] 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.

[0020] 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.

[0021] Preferably, the lever arms are each designed separately and arranged such that the lever arms are interchangeable 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.

[0022] 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.

[0023] The invention further relates to a bicycle with a bicycle damper (1) having the features of one of claims 1 to 13.

[0024] Exemplary embodiments of the invention are explained in more detail below with reference to the figures. Like reference numerals denote like components. They show schematically: Fig. 1 - a side view of a bicycle damper according to the invention; Fig. 2 - a perspective view of the bicycle shock absorber according to Fig. 1; Fig. 3 - a side sectional view of the bicycle damper according to Fig. 1; Fig. 4 - a perspective view of the bicycle shock absorber according to Fig. 1 without saddle attachment device; Fig. 5a and Fig. 5b - a side view of the bicycle damper according to Fig. 1 without elastomer part in an undamped and a damped state; Fig. 6 - a perspective detailed view of the lever arms of the bicycle shock absorber according to Fig. 1; Fig. 7 - a perspective detailed view of the elastomer part of the bicycle damper according to Fig. 1; Fig. 8a and Fig. 8b - a partial side view of a bicycle with a bicycle damper according to Fig. 1; Fig. 9a and Fig. 9b - a partial side view of a bicycle with a bicycle damper according to the invention in a partially sectioned representation; and Fig. 10a and Fig. 10b - each a partial side view of a bicycle with a bicycle damper according to the invention in a partially sectioned representation.

[0025] In the Fig. 1, reference numeral 1 denotes a bicycle damper according to the invention, in particular a bicycle saddle damper 1'. The bicycle saddle damper 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 a bicycle frame 10 (not shown in detail here).

[0026] 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 17 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), and a second frame part 12, also called the upper tube section, which faces away from the bicycle frame 10 (not shown) and faces the saddle mounting device 13.

[0027] As particularly in the Fig. 1, Fig. 2 and Fig. As can be seen in Figure 4, 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 their longitudinal extension. 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). As shown in Fig. As shown in Figure 4, the second frame part 12 has a saddle mounting device 13 at a distal end facing away from the first frame part 11, to which the saddle (not shown here) can be mounted via the fastening device 17. The saddle mounting device 13 and / or the fastening device 17 define an axis A1 in their longitudinal extension, which forms a transverse axis with respect to a bicycle 100, which is arranged in particular perpendicular to a straight-ahead travel of the bicycle 100.

[0028] 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.

[0029] The damping device 2, which is used in particular in Fig. 3 can be seen in detail, 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 perpendicular 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 pivotally mounted 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, as shown in particular in . Fig. 6 - a total of four plain bearings 8, 8', 8'', 8''' are provided for each lever arm 3a, 3b, so that the lever arms 3a, 3b can swing freely. Furthermore, the damping device 2 comprises a deformable elastomer part 4, which 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.

[0030] As particularly in Fig. 2, Fig. 4, Fig. 5a and Fig. 5b, the separately formed lever arms 3a, 3b are arranged such that they can be exchanged independently of one another and independently of the mounted elastomer part 4 and 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 recesses the lever arms can extend with an end 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, easy visual inspection of the lever arm 3a, 3b is possible.

[0031] 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 shown in the Fig. 1 to 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.

[0032] As particularly in Fig. As shown in Figure 7, the elastomer part 4 is S-shaped. 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.

[0033] When the lever arms 3a, 3b are passed through the recesses 6a, 6b, 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, in this case in particular via a slide bearing 8, 8', 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 accuracy of fit of the recesses 6a, 6b.

[0034] In the event of an impact on the seat post tube 16 or any other load on 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 on 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. The axis A1 is thus displaced primarily in the direction R1 of the longitudinal extension of the post 16. To clarify the movement of the lever arms 3a, 3b, Fig. 5a and Fig. 5b shows a bicycle damper 1, 1' without the elastomer part 4, in particular in two different immersed states of the frame parts 11, 12.

[0035] In the Fig. 8a and Fig. Finally, Figure 8b shows a state of the bicycle damper 1, 1' installed on a bicycle 100. Here, the Fig. 8a, the saddle receiving device 13, which is adjacent to the second frame part 12, is shown in a non-submerged state, while in Fig. 8b shows a submerged state. This allows shocks to be reduced and dampened particularly effectively.

[0036] In the Fig. 9a and Fig. 9b shows a partial side view of a bicycle 100 with a bicycle frame 10 and a bicycle shock absorber 1 arranged thereon, in a partially sectioned view. 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.

[0037] In the Fig. 10a and Fig. 10b also shows a partial side view of a bicycle 100 with a bicycle frame 10 and a bicycle shock absorber 1 arranged thereon, in a partially sectioned illustration. The bicycle shock absorber 1 is arranged in a front wheel strut, in particular a front wheel fork, which connects a front wheel mount to the rest of the bicycle frame, in particular in the direction of a handlebar. With this arrangement, a shock occurring at the front wheel can be dampened particularly effectively.

[0038] Since the system described above is not only suitable for seat posts, it can also be applied to a handlebar post, rear wheel stay, or front wheel fork. 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.
