[0018] The embodiments are now described with reference to the attached drawings, whereby in the respective drawings the same numbers denote corresponding or identical elements. First embodiment

[0019] Initially, with reference to Fig. 1. A bicycle derailleur 10 according to a first embodiment comprises a base component 12, a chain guide 14, and a first link 16. The base component 12 is configured to be coupled to a bicycle frame 2. In the illustrated embodiment, the base component 12 is detachably and reinstallably attached to the seat tube 2a of the bicycle frame 2. The chain guide 14 is configured to guide a bicycle chain 4. Specifically, the chain guide 14 is configured to displace the bicycle chain 4 in the transverse direction D1 of the bicycle (not shown). The first link 16 is configured to couple the chain guide 14 to the base component 12 such that the chain guide 14 is movable relative to the base component 12 between a retracted position P1 and an extended position P2. For example, in the transverse direction D1, the retracted position P1 is closer to the bicycle frame 2 than the extended position P2.

[0020] In this embodiment, the following directional terms “front”, “back”, “forward”, “backward”, “left”, “right”, “across”, “up”, and “down”, as well as other similar directional expressions, refer to those directions that are determined, for example, based on the cyclist sitting in the saddle (not shown) of a bicycle (not shown) facing the handlebars. Consequently, these terms, as used to describe the bicycle derailleur 10, should be interpreted in relation to the bicycle being used in an upright riding position on a horizontal surface.

[0021] The bicycle derailleur 10 includes a second link 18 configured to couple the chain guide 14 to the base component 12 such that the chain guide 14 is movable relative to the base component 12 between the retracted position P1 and the extended position P2. Even though the first link 16 is closer to the bicycle frame 2 in the transverse direction D1 than the second link 18, the first link 16 can also be positioned further away from the bicycle frame 2 in the transverse direction D1 than the second link 18, as required and / or desired. That is, the positions of the first link 16 and the second link 18 can be interchanged. Furthermore, the second link 18 can also be omitted from the bicycle derailleur 10 as required and / or desired.

[0022] As in Fig. As shown in Figure 1, the first link 16 comprises a first body 20, a first connecting pin 22, and a second connecting pin 24. The first connecting pin 22 is configured to pivotally couple the first body 20 to the base component 12 about a first swing axis A1. The second connecting pin 24 is configured to pivotally couple the first body 20 to the chain guide 14 about a second swing axis A2. The second link 18 comprises a second body 26, a third connecting pin 28, and a fourth connecting pin 30. The third connecting pin 28 is configured to pivotally couple the second body 26 to the base component 12 about a third swing axis A3. The fourth connecting pin 30 is configured to pivotally couple the second body 26 to the chain guide 14 about a fourth swing axis A4.

[0023] The first to fourth connecting pins 22, 24, 28 and 30 form a four-way joint. Even if the first to fourth swing axes A1 to A4 are essentially parallel to each other, at least one of the first to fourth swing axes A1 to A4 can be non-parallel to the other axes if required and / or desired.

[0024] Even though, in the illustrated embodiment, the first connecting pin 22 and the second connecting pin 24 are components separate from the first body 20, at least one of the first connecting pin 22 and the second connecting pin 24 can be integrally provided with the first body 20 as a single unitary component, as required and / or desired. Similarly, even though, in the illustrated embodiment, the third connecting pin 28 and the fourth connecting pin 30 are components separate from the second body 26, at least one of the third connecting pin 28 and the fourth connecting pin 30 can be integrally provided with the second body 26 as a single unitary component, as required and / or desired.

[0025] The bicycle derailleur 10 comprises an adjusting assembly 32 configured to set the retracted position P1 and the extended position P2. The adjusting assembly 32 includes a first adjusting screw 34 and a second adjusting screw 36. The first adjusting screw 34 and the second adjusting screw 36 are screwed to the base component 12. The first link 16 is configured to contact the first adjusting screw 34 in a retracted state, where the chain guide 14 is positioned in the retracted position P1. The first link 16 is configured to contact the second adjusting screw 36 in an extended state, where the chain guide 14 is positioned in the extended position P2. The adjusting assembly 32 can be omitted from the bicycle derailleur 10 as required and / or desired.The positions of the first and second adjusting screws 34 and 36, relative to the base component 12, can each be adjusted so that the contact points between the first and second adjusting screws 34 and 36 and the first link 16 are changed. This allows the retracted position P1 and the extended position P2 to be set.

[0026] The bicycle derailleur 10 includes a pre-tensioning component (not shown) configured to pre-tension the chain guide 14 towards the retracted position P1. The chain guide 14 is positioned in the retracted position P1 by the actuating mechanism 32 and the pre-tensioning component when the shift cable 5 of the control cable 6 is not tightened.

[0027] As in Fig. As can be seen in Figure 1, the bicycle derailleur 10 includes a cable guide 38. The cable guide 38 is a component separate from the first link 16. The cable guide 38 is configured to be attached to the first link 16. The cable guide 38 comprises only one cable guide section 40, which is configured to guide the shift cable 5 of the control cable 6, which is located in at least one of a top-pull arrangement and one of a bottom-pull arrangement.

[0028] In the illustrated embodiment, the cable guide section 40 is configured to guide the shift cable 5 of the control cable 6, which is located in both the top-pull and bottom-pull arrangements. Specifically, the cable guide section 40 is configured to guide the shift cable 5 of the control cable 6 only in the top-pull arrangement. The cable guide section 40 is not configured to guide the shift cable 5 of the control cable 6 in the bottom-pull arrangement. In the top-pull arrangement, the chain guide 14 is moved from the retracted position P1 to the extended position P2 when the shift cable 5 is pulled upwards relative to the cable guide section 40 via a shift lever (not shown).

[0029] As in Fig. As shown in Figure 1, the cable guide section 40 includes a guide bore 42 through which the shift cable 5 is to run. The cable guide section 40 is configured to absorb an upward tensile force F1 exerted on the shift cable 5. The first link 16 pivots about the first pivot axis A1 in response to the upward tensile force F1 relative to the base component 12.

[0030] As in the Fig. 1 and Fig. As can be seen in Figure 2, the rope guide 38 is configured so that it can be detachably attached to the first link 16, allowing it to be replaced with another rope guide. As shown in Fig. As can be seen in Figure 2, the bicycle derailleur 10 also includes a further cable guide 44. The further cable guide 44 is a component separate from the first link 16 and the cable guide 38 ( Fig. 1) The additional cable guide 44 is configured so that it can be attached to the first link 16. The cable guide 38 and the additional cable guide 44 can be selectively attached to the first link 16 during the assembly of the bicycle derailleur 10. Fig. Figure 1 illustrates a first fastening state in which the rope guide 38 is attached to the first link 16. Fig. Figure 2 illustrates a second fastening state in which the further rope guide 44 is attached to the first link 16.

[0031] As in the Fig. 1 and Fig. As shown in Figure 2, in the illustrated embodiment, the cable guide 38 and the further cable guide 44 are configured so that they can be detachably attached to the first link 16, allowing them to be interchanged. However, the cable guide 38 can also be permanently attached to the first link 16, and the further cable guide 44 can also be permanently attached to the first link 16. If the cable guide 38 is permanently attached to the first link 16, for example, it cannot be detached from the first link 16 without destroying a coupling section between the cable guide 38 and the first link 16. Similarly, if the further cable guide 44 is permanently attached to the first link 16, it cannot be detached from the first link 16 without destroying a coupling section between the further cable guide 44 and the first link 16.

[0032] As in Fig. As shown in Figure 2, the additional cable guide 44 includes a further cable guide section 46, which is configured to guide the switching cable 5 of the control cable 6, which is located in a different configuration than the top-pull and bottom-pull arrangements. In the illustrated embodiment, the additional cable guide 44 is configured to guide the switching cable 5 of the control cable 6 only when it is located in the bottom-pull arrangement. The additional cable guide 44 is not configured to guide the switching cable 5 of the control cable 6 when it is located in the top-pull arrangement. Fig. 1) In the bottom-pull arrangement, the chain guide 14 is moved from the retracted position P1 towards the extended position P2 when the shift cable 5 is pulled downwards relative to the cable guide section 46 by means of the shift lever (not shown).

[0033] The further cable guide section 46 includes a further guide bore 48 through which the switching cable 5 is to run. The further cable guide section 46 is configured to absorb a downward tensile force F2 exerted on the switching cable 5. The first link 16 pivots about the first pivot axis A1 in response to the downward tensile force F2 relative to the base component 12.

[0034] As in Fig. As can be seen in Figure 1, the first link 16 comprises a first end 16a and a second end 16b. The first link 16 runs between the first end 16a and the second end 16b. The first end 16a is configured to be pivotably coupled to the base component 12 about the first swingarm axis A1. The second end 16b is configured to be pivotably coupled to the chain guide 14 about the second swingarm axis A2.

[0035] As in the Fig. 1 and Fig. 2 can be seen, viewed from the axial direction of the first swing axis A1 (a direction perpendicular to the paper surface of the Fig. 1 and Fig. 2) In the first and second mounting states, the cable guide section 40 of the cable guide 38 is arranged relative to a reference line RL1, which runs between the first end 16a and the second end 16b, opposite the further cable guide section 46 of the further cable guide 44. The reference line RL1 runs such that it overlaps the first end 16a and the second end 16b. In the illustrated embodiment, viewed from the axial direction of the first swing axis A1, in the first and second mounting states, the cable guide section 40 of the cable guide 38 is arranged relative to the first link 16 opposite the further cable guide section 46 of the further cable guide 44. Viewed from the axial direction of the first swing axis A1, in the first and second mounting states, the guide bore 42 is provided relative to the first link 16 opposite the further guide bore 48.The cable guide section 40 can comprise at least one groove, a recess, and a projection instead of or in addition to the guide bore 42. The further cable guide section 46 can comprise at least one groove, a recess, and a projection instead of or in addition to the further guide bore 48.

[0036] As in the Fig. 1 and Fig. As can be seen in Figure 2, viewed from the axial direction of the first swingarm axis A1, in the first and second mounting states, the cable guide section 40 of the cable guide 38 is further away from the seat tube 2a than the further cable guide section 46 of the further cable guide 44. Furthermore, viewed from the axial direction of the first swingarm axis A1, in the first and second mounting states, the cable guide section 40 of the cable guide 38 is arranged in a lower position in the axial direction D2 of the seat tube 2a than the further cable guide section 46 of the further cable guide 44.

[0037] In the illustrated embodiment, the first swing axis A1 is parallel to the second swing axis A2. In this embodiment, the reference line RL1 can be defined by the first swing axis A1 and the second swing axis A2. The reference line RL1 intersects the first swing axis A1 and the second swing axis A2.

[0038] As in the Fig. 1, Fig. 2 to Fig. As shown in FIG. 3, the first link 16 comprises a cable fastening assembly 50. As shown in FIG. 3, the cable fastening assembly 50 comprises a fastening base section 52, a washer 54, and a cable fastening screw 56. The fastening base section 52 is provided on the first body 20 and projects from the first body 20. The fastening base section 52 includes a threaded bore 52a. The washer 54 includes a through bore 54a. The cable fastening screw 56 passes through the through bore 54a and is screwed into the threaded bore 52a. The shift cable 5 is inserted between the fastening base section 52 and the washer 54 such that the shift cable 5 is secured to the first link 16.

[0039] As in the Fig. 1 and Fig. As shown in Figure 3, the cable guide 38 includes an engagement opening 58. The mounting base section 52 is provided in the engagement opening 58 when the cable guide 38 is attached to the first link 16. The cable guide 38 is positioned relative to the first link 16 by the mounting base section 52 and the engagement opening 58 such that the cable guide 38 moves together with the first link 16 in response to a tensile force via the switching cable 5. The mounting base section 52 is configured to prevent movement of the cable guide 38 relative to the first link 16.

[0040] As in Fig. As shown in Figure 3, the cable guide 38 comprises a pivot bore 60 and a mounting bore 62. The first connecting pin 22 passes through the pivot bore 60. A retaining ring 64 is attached to one end of the first connecting pin 22. The cable guide 38 is secured to the first body 20 by a mounting screw 66. The mounting screw 66 passes through the mounting bore 62 and is screwed into the threaded bore 68 of the first body 20. By removing the retaining ring 64 and the mounting screw 66, the cable guide 38 can be detached from the first link 16.

[0041] As in the Fig. 2 and Fig. As shown in Figure 3, the additional cable guide 44 includes a further engagement opening 70. The mounting base section 52 is provided in the further engagement opening 70 when the additional cable guide 44 is attached to the first link 16. The additional cable guide 44 is positioned relative to the first link 16 by the mounting base section 52 and the further engagement opening 70 such that the additional cable guide 44 moves together with the first link 16 in response to a tensile force via the switching cable 5. The mounting base section 52 is configured to prevent movement of the additional cable guide 44 relative to the first link 16.

[0042] As in Fig. As shown in Figure 3, the additional cable guide 44 comprises a pivot bore 72 and a mounting bore 74. The first connecting pin 22 passes through the pivot bore 72. The additional cable guide 44 is secured to the first body 20 by the mounting screw 66. The mounting screw 66 passes through the mounting bore 74 and is screwed into the threaded bore 68 of the first body 20. By removing the retaining ring 64 and the mounting screw 66, the additional cable guide 44 can be detached from the first link 16.

[0043] As in Fig. As shown in Figure 3, even if the cable guide 38 is attached to the rear of the first link 16 in the axial direction of the first swing axis A1, the cable guide 38 can also be attached to the front of the first link 16 or in a central section of the first link 16 in the axial direction of the first swing axis A1. Similarly, even if the further cable guide 44 is attached to the rear of the first link 16 in the axial direction of the first swing axis A1, the cable guide 38 can also be attached to the front of the first link 16 or the central section of the first link 16 in the axial direction of the first swing axis A1.

[0044] Even if the position of the rope guide 38 relative to the first link 16 is essentially the same as the position of the further rope guide 44, the position of the rope guide 38 relative to the first link 16 can also be different from the position of the further rope guide 44. For example, the rope guide 38 can be arranged on one side of the front and back of the first link 16, and the further rope guide 44 can be arranged on the other side of the front and back of the first link 16. Furthermore, the rope guide 38 can be attached to one side of the first link 16 and the second link 18, and the further rope guide 44 can be arranged on the other side of the first link 16 and the second link 18.

[0045] In the bicycle derailleur 10, the cable guide 38 comprises only one cable guide section 40, which is configured to guide the shift cable 5 of the control cable 6, which is located in at least one of the top-pull and bottom-pull arrangements. The cable guide 38 is a separate component from the first link 16 and is configured to be attached to the first link 16. Consequently, the cable guide 38 can be exchanged for another cable guide (e.g., the additional cable guide 44), or a combination of the cable guide 38 and another cable guide (e.g., the additional cable guide 44) can be selected for attachment to the same first link 16, thus enabling the bicycle derailleur 10 to be used for both top-pull and bottom-pull arrangements using a simple design.

[0046] Below, a bicycle derailleur 210 according to a second embodiment is described with reference to the Fig. 4, Fig. 5 to Fig. 6 described. The bicycle derailleur 210 has the same configuration as the bicycle derailleur 10, except for the cable guide 38 and the further cable guide 44. Therefore, elements with essentially the same function as those in the first embodiment are numbered the same and, for the sake of brevity, are not described and / or illustrated again in detail.

[0047] As in Fig. As shown in Figure 4, the bicycle derailleur 210 does not include the additional cable guide 44 according to the first embodiment. The bicycle derailleur 210 includes a cable guide 238, which comprises only one cable guide section 240 configured to guide the shift cable 5 of the control cable 6, which is located in at least one of the top-pull and bottom-pull arrangements. In the illustrated embodiment, the cable guide section 240 is configured to guide the shift cable 5 of the control cable 6, which is located in both the top-pull and bottom-pull arrangements. The cable guide 238 is a component separate from the first link 16 and is configured to be attached to the first link 16.

[0048] As in the Fig. 4 and Fig. As can be seen in Figure 5, the rope guide 238 is configured so that it can be attached to the first link 16 in such a way that the rope guide 238 is in a first orientation relative to the first link 16 ( Fig. 4) and a second orientation ( Fig. 5) is arranged. During assembly of the bicycle derailleur 210, the cable guide 238 can be selectively attached to the first link 16 in the first and second orientations. The cable guide 238 is configured so that it can be detachably attached to the first link 16. However, the cable guide 238 can also be permanently attached to the first link 16. If the cable guide 238 is permanently attached to the first link 16, for example, the cable guide 238 cannot be detached from the first link 16 without destroying a coupling section between the cable guide 238 and the first link 16.

[0049] The second orientation differs from the first. In the illustrated embodiment, the second orientation is one in which the cable guide 38 is rotated approximately 180 degrees from the first orientation about an axis of rotation parallel to the first swing axis A1 with respect to the first link 16. Specifically, the second orientation is one in which the cable guide 38 is rotated approximately 180 degrees from the first orientation about the first swing axis A1 with respect to the first link 16. Although the axis of rotation of the first and second orientations coincides with the first swing axis A1, the axis of rotation can also be defined in a different position than the first swing axis A1. For example, the axis of rotation can be parallel to the second swing axis A2, which is not parallel to the first swing axis A1.Furthermore, the first and second orientations are not limited to the illustrated embodiment.

[0050] As in Fig. As shown in Figure 4, the cable guide section 240 is configured to guide the switching cable 5 of the control cable 6, which in a first state, in which the cable guide 238 is arranged in the first orientation with respect to the first link 16, is in a top-pull arrangement and a bottom-pull arrangement. In the illustrated embodiment, the cable guide section 240 is configured in the first state to guide the switching cable 5 of the control cable 6, which is in the top-pull arrangement.

[0051] As in Fig. As can be seen in Figure 5, the cable guide section 240 is configured to guide the switching cable 5 of the control cable 6, which is located in the other configuration between the top-pull and bottom-pull arrangements, in a second state in which the cable guide 238 is arranged in the second orientation relative to the first link 16. In the illustrated embodiment, the cable guide section 240 is configured in the second state to guide the switching cable 5 of the control cable 6, which is located in the bottom-pull arrangement.

[0052] As in the Fig. 4 and Fig. 5 can be seen, viewed from the axial direction of the first swing axis A1 (a direction perpendicular to the paper surface of the Fig. 4 and Fig. 5), the rope guide section 240 in the first state ( Fig. 4) of the rope guide 238 with respect to the reference line RL1, which runs between the first end 16a and the second end 16b, compared to the rope guide section 240 in the second state ( Fig. 5) of the cable guide 238. In the illustrated embodiment, viewed from the axial direction of the first swing axis A1, the cable guide section 240 in the first state of the cable guide 238 is arranged relative to the first link 16 compared to the cable guide section 240 in the second state of the cable guide 238.

[0053] As in the Fig. 4 and Fig. Figure 5 shows, viewed from the axial direction of the first swing axis A1, the position of the cable guide section 240 in the first state ( Fig. 4) further away from the seat tube 2a than the position of the cable guide section 240 in the second state ( Fig. 5) Furthermore, viewed from the axial direction of the first swing arm axis A1, the position of the cable guide section 240 in the first state is lower in the axial direction D2 of the seat tube 2a than the position of the cable guide section 240 in the second state.

[0054] As in Fig. As shown in Figure 4, the cable guide section 240 includes a guide bore 242 through which the shift cable 5 is to run. The cable guide section 240 is configured to absorb the upward tensile force F1 exerted on the shift cable 5 in the first state. In the first state, the first link 16 pivots about the first pivot axis A1 in response to the upward tensile force F1 relative to the base component 12. The cable guide section 240 can include at least one groove, a recess, and a projection instead of or in addition to the guide bore 242.

[0055] As in Fig. As can be seen in Figure 5, the cable guide section 240 is configured to absorb the downward tensile force F2 exerted on the shift cable 5 in the second state. In response to the downward tensile force F2, the first link 16 pivots about the first pivot axis A1 relative to the base component 12 in the second state.

[0056] As in the Fig. 4 and Fig. As shown in Figure 6, the cable guide 238 comprises a first engagement opening 258 and a second engagement opening 259. In the first state, the fastening base section 52 is positioned in the first engagement opening 258. In the first state, the cable guide 238 is positioned relative to the first link 16 by the fastening base section 52 and the first engagement opening 258. The fastening base section 52 is configured such that, in the first state, it prevents movement of the cable guide 238 relative to the first link 16.

[0057] As in the Fig. 5 and Fig. As can be seen in Figure 6, in the second state, the mounting base section 52 is positioned in the second engagement opening 259. In the second state, the cable guide 238 is positioned relative to the first link 16 by the mounting base section 52 and the second engagement opening 259. The mounting base section 52 is configured such that, in the second state, it prevents movement of the cable guide 238 relative to the first link 16.

[0058] As in Fig. As can be seen in Figure 6, the cable guide 238 comprises a joint bore 260, a first fastening bore 262, and a second fastening bore 263. The first connecting pin 22 passes through the joint bore 260. In the first state, the fastening screw 66 passes through the first fastening bore 262 ( Fig. 4) In the second state, the fastening screw 66 passes through the second fastening hole 263 ( Fig. 5) By removing the retaining ring 64 and the fastening screw 66, the cable guide 238 can be detached from the first link 16 and moved to a position different from the first orientation ( Fig. 4) and the second alignment ( Fig. 5) attached to the first member 16. In the illustrated embodiment, as shown in the Fig. 4 and Fig. As can be seen in Figure 5, the joint bore 260 is present in both the first and second orientations.

[0059] As in Fig. As can be seen in Figure 6, even if the cable guide 238 is attached to the rear of the first link 16 in the axial direction of the first swing axis A1, the cable guide 238 can also be attached to the front of the first link 16 or the central section of the first link 16 in the axial direction of the first swing axis A1. Even if the position of the cable guide 238 in the first state ( Fig. 4) with respect to the first link 16 is essentially the same as the position of the rope guide 238 in the second state ( Fig. 5) The position of the rope guide 238 in the first state, relative to the first link 16, can also differ from the position of the rope guide 238 in the second state. For example, the rope guide 238 can be arranged on one side of the front and back of the first link 16 in the first state, and the rope guide 238 can be arranged on the other side of the front and back of the first link 16 in the second state. Furthermore, the rope guide 238 can be attached to the second link 18.

[0060] The bicycle derailleur 210 can achieve essentially the same advantageous effect as the bicycle derailleur 10 according to the first embodiment.

[0061] Below is a bicycle derailleur 310 according to a third embodiment with reference to the Fig. 7, Fig. 8 to Fig. 9 described. The bicycle derailleur 310 has the same configuration as the bicycle derailleur 10, except for the cable guide 38 and the further cable guide 44. Therefore, elements with essentially the same function as those in the above embodiments are numbered the same and, for the sake of brevity, are not described and / or illustrated again in detail.

[0062] As in Fig. As shown in Figure 7, the bicycle derailleur 310 includes a cable guide 338, which comprises only one cable guide section 340 configured to guide the shift cable 5 of the control cable 6, which is located in at least one of the top-pull and bottom-pull arrangements. In the illustrated embodiment, the cable guide section 340 is configured to guide the shift cable 5 of the control cable 6, which is located in both the top-pull and bottom-pull arrangements. The cable guide 338 is a component separate from the first link 16 and is configured to be attached to the first link 16.

[0063] As in the Fig. 7 and Fig. As can be seen in Figure 8, the rope guide 338 is configured so that it can be attached to the first link 16 in such a way that the rope guide 338 is in a first orientation relative to the first link 16 ( Fig. 7) and a second orientation ( Fig. 8) is arranged. During assembly of the bicycle derailleur 310, the cable guide 338 can be selectively attached to the first link 16 in the first orientation and the second orientation. The cable guide 338 is configured so that it can be detachably attached to the first link 16. However, the cable guide 338 can also be permanently attached to the first link 16. If the cable guide 338 is permanently attached to the first link 16, it cannot be detached from the first link 16 without destroying a coupling section between the cable guide 338 and the first link 16.

[0064] The second orientation differs from the first orientation. In the illustrated embodiment, as shown in Fig. As can be seen in Figure 9, the cable guide 338, in a direction parallel to the first swing axis A1, which the cable guide 338 crosses, comprises a first side S1 and a second side S2 opposite the first side S1. The second orientation is an orientation in which the cable guide 338 is reversed such that the positions of the first side S1 and the second side S2 are exchanged with respect to the first link 16.

[0065] As in the Fig. 7 and Fig. As can be seen in Figure 8, the cable guide 338 between the first orientation and the second orientation is referenced to a reference line RL2, viewed from the axial direction of the first swing axis A1 (a direction perpendicular to the paper surface of the Fig. 7 and Fig. 8), reversed. That is, the reference line RL2 is an axis of symmetry of the first and second orientations of the cable guide 338. The reference line RL2 is essentially perpendicular to the first swing axis A1. In the illustrated embodiment, the reference line RL2 is inclined relative to the reference line RL1. The reference line RL2 can also coincide with the reference line RL1 if required and / or desired.

[0066] As in Fig. As can be seen in Figure 7, the cable guide section 340 is configured to guide the switching cable 5 of the control cable 6, which is located in either the top-pull or bottom-pull arrangement, in the first state, in which the cable guide 338 is arranged in the first orientation with respect to the first link 16. In the illustrated embodiment, the cable guide section 340 is configured in the first state to guide the switching cable 5 of the control cable 6, which is located in the top-pull arrangement. As shown in Figure 7, the cable guide section 340 is configured to guide the switching cable 5 of the control cable 6, which is located in the top-pull arrangement. Fig. As can be seen in 9, in the first state the first side S1 is opposite the first link 16 in relation to the second side S2.

[0067] As in Fig. As shown in Figure 8, the cable guide section 40 is configured to guide the switching cable 5 of the control cable 6, which is located in the other configuration between the top-pull and bottom-pull arrangements, in the second state, in which the cable guide 338 is arranged in the second orientation relative to the first link 16. In the illustrated embodiment, the cable guide section 340 is configured in the second state to guide the switching cable 5 of the control cable 6, which is located in the bottom-pull arrangement. As shown in Figure 8, the cable guide section 40 is configured to guide the switching cable 5 of the control cable 6, which is located in the bottom-pull arrangement. Fig. As can be seen in 9, in the second state the second side S2 is opposite the first link 16 in relation to the first side S1.

[0068] As in the Fig. 7 and Fig. Figure 8 shows, viewed from the axial direction of the first swing axis A1 (a direction perpendicular to the paper surface of the Fig. 7 and Fig. 8) The cable guide section 340 in the first state of the cable guide 338 is arranged relative to the reference line RL1 in relation to the cable guide section 340 in the second state of the cable guide 338. Viewed from the axial direction of the first swing axis A1, the cable guide section 340 in the first state of the cable guide 338 is arranged relative to the first link 16 in relation to the cable guide section 340 in the second state of the cable guide 338. Furthermore, viewed from the axial direction of the first swing axis A1, the cable guide section 340 in the first state of the cable guide 338 is arranged relative to the reference line RL2 in relation to the cable guide section 340 in the second state of the cable guide 338.

[0069] As in the Fig. 7 and Fig. Figure 8 shows, viewed from the axial direction of the first swing axis A1, the position of the cable guide section 340 in the first state ( Fig. 7) further away from the seat tube 2a than the position of the cable guide section 340 in the second state ( Fig. 8) Furthermore, viewed from the axial direction of the first swing arm axis A1 in the axial direction D2 of the seat tube 2a, the position of the cable guide section 340 in the first state is lower than the position of the cable guide section 340 in the second state.

[0070] As in Fig. As shown in Figure 7, the cable guide section 340 includes a guide bore 342 through which the shift cable 5 is to run. In the first state, the cable guide section 340 is configured to absorb the upward tensile force F1 exerted on the shift cable 5. In the first state, the first link 16 pivots about the first pivot axis A1 in response to the upward tensile force F1 relative to the base component 12. The cable guide section 340 can include at least one groove, a recess, and a projection instead of or in addition to the guide bore 342.

[0071] As in Fig. As can be seen in Figure 8, the cable guide section 340 is configured in the second state to absorb the downward tensile force F2 exerted on the shift cable 5. In the second state, the first link 16 pivots about the first pivot axis A1 in response to the downward tensile force F2 relative to the base component 12.

[0072] As in the Fig. 7, Fig. 8 to Fig. As can be seen in Figure 9, the cable guide 338 includes an access opening 358. As shown in the Fig. 7 and Fig. As can be seen in Figure 9, the mounting base section 52 is positioned in the engagement opening 358 in the first state. In the first state, the cable guide 338 is positioned relative to the first link 16 by the mounting base section 52 and the engagement opening 358. The mounting base section 52 is configured in the first state such that it prevents movement of the cable guide 338 relative to the first link 16.

[0073] As in the Fig. 8 and Fig. As can be seen in Figure 9, the mounting base section 52 is positioned in the engagement opening 358 in the second state. In the second state, the cable guide 338 is positioned relative to the first link 16 by the mounting base section 52 and the engagement opening 358. In the second state, the mounting base section 52 is configured to prevent movement of the cable guide 338 relative to the first link 16.

[0074] As in Fig. As can be seen in Figure 9, the cable guide 338 comprises a joint bore 360, a first fastening bore 362, and a second fastening bore 363. The first connecting pin 22 passes through the joint bore 360. In the first state, the fastening screw 66 passes through the first fastening bore 362 ( Fig. 7). In the second state, the fastening screw 66 passes through the second fastening hole 363 ( Fig. 8) By removing the retaining ring 64 and the fastening screw 66, the cable guide 338 can be detached from the first link 16 and moved to a position different from the first orientation ( Fig. 7) and the second orientation ( Fig. 8) attached to the first member 16. In the illustrated embodiment, as shown in the Fig. 7 and Fig. As can be seen in Figure 8, the 360° joint bore is present in both the first and second orientations. However, the joint bore in the first orientation may differ from the joint bore in the second orientation.

[0075] As in Fig. As can be seen in Figure 9, even if the cable guide 338 is attached to the rear of the first link 16 in the axial direction of the first swing axis A1, the cable guide 338 can also be attached to the front of the first link 16 or the central section of the first link 16 in the axial direction of the first swing axis A1. Even if the position of the cable guide 338 in the first state ( Fig. 7) with respect to the first link 16 is essentially the same as the position of the rope guide 338 in the second state ( Fig. 8) The position of the rope guide 338 in the first state, relative to the first link 16, can also differ from the position of the rope guide 338 in the second state. For example, in the first state, the rope guide 338 can be arranged on one side of the front and the back of the first link 16, and in the second state, the rope guide 338 can be arranged on the other side of the front and the back of the first link 16. Furthermore, the rope guide 338 can be attached to the second link 18.

[0076] The bicycle derailleur 310 can achieve essentially the same advantageous effect as the bicycle derailleur 10 according to the first embodiment.

[0077] Below is a bicycle derailleur 410 according to a fourth embodiment with reference to the Fig. 10, Fig. 11 to Fig. 12 described. The bicycle derailleur 410 has the same configuration as the bicycle derailleur 10, except for the cable guide 38 and the further cable guide 44. Therefore, elements with essentially the same function as those in the above embodiments are numbered the same and, for the sake of brevity, are not described and / or illustrated again in detail.

[0078] As in the Fig. 10 and Fig. As can be seen in Figure 11, the bicycle derailleur 410 includes a cable guide 438, which is a separate component from the first link 16. The cable guide 438 is configured so that it can be attached to the first link 16 in such a way that the cable guide 438 is in a position different from a first orientation ( Fig. 10) and a second orientation ( Fig. 11) is arranged with respect to the first link 16. When assembling the bicycle derailleur 410, the cable guide 438 can be selectively attached to the first link 16 in the first orientation and the second orientation. The second orientation differs from the first orientation. The cable guide 438 is configured so that it can be detachably attached to the first link 16. However, the cable guide 438 can also be configured so that it is permanently attached to the first link 16. If the cable guide 438 is permanently attached to the first link 16, for example, the cable guide 438 cannot be detached from the first link 16 without destroying a coupling section between the cable guide 438 and the first link 16. The cable guide 438 comprises a top-pull cable guide section 440 and a bottom-pull cable guide section 441.

[0079] As in Fig. As shown in Figure 10, the top-pull cable guide section 440 is in a first state, where the cable guide 438 is in its first orientation relative to the first link 16, configured to guide the shift cable 5 of the control cable 6. In this first state, the top-pull cable guide section 440 is configured to absorb the upward pull force F1 exerted on the shift cable 5. In this first state, the first link 16 pivots about the first pivot axis A1 in response to the upward pull force F1 relative to the base component 12.

[0080] As in Fig. As shown in Figure 11, the bottom-pull cable guide section 441 is configured to guide the shift cable 5 of the control cable 6 in a second state, in which the cable guide 438 is in its second orientation relative to the first link 16. In this second state, the bottom-pull cable guide section 441 is configured to absorb the downward pulling force F2 exerted on the shift cable 5. In this second state, the first link 16 pivots about the first pivot axis A1 in response to the downward pulling force F2 relative to the base component 12.

[0081] As in the Fig. 10 and Fig. As can be seen in Figure 11, the bottom-pull cable guide section 441 differs from the top-pull cable guide section 440. The bottom-pull cable guide section 441 is provided separately from the top-pull cable guide section 440. At least one of the top-pull cable guide section 440 and the bottom-pull cable guide section 441 includes a guide bore through which the switching cable 5 is to run.

[0082] In the illustrated embodiment, as shown in Fig. As can be seen in Figure 10, the top-pull cable guide section 440 includes a guide bore 442 through which the shift cable 5 is to run. As shown in Fig. As shown in Figure 11, the bottom-pull cable guide section 441 includes a guide bore 443 through which the switching cable 5 is to run. The guide bore 443 is provided separately from the guide bore 442 and is not connected to the guide bore 442. However, the guide bore 443 can also be connected to the guide bore 442 as required and / or desired, thus providing a single opening. The top-pull cable guide section 440 can include at least one groove, a recess, and a projection instead of or in addition to the guide bore 442. The bottom-pull cable guide section 441 can include at least one groove, a recess, and a projection instead of or in addition to the guide bore 443.

[0083] As in Fig. As can be seen in Figure 10, viewed from the axial direction of the first swing axis, the top-pull rope guide section 440 and the bottom-pull rope guide section 441 are arranged on a first rope side WS1 in the first state with respect to the reference line RL1, which runs between the first end 16a and the second end 16b.

[0084] As in Fig. As can be seen in Figure 11, viewed from the axial direction of the first swing axis, the top-pull rope guide section 440 and the bottom-pull rope guide section 441 are arranged on a second rope side WS2 in the second state with respect to the reference line RL1. The second rope side WS2 is opposite the first rope side WS1 with respect to the reference line RL1.

[0085] As in the Fig. 10 and Fig. Figure 11 shows, viewed from the axial direction of the first swing axis A1, the position of the cable guide section 440 in the first state ( Fig. 10) further away from the seat tube 2a than the position of the cable guide section 440 in the second state ( Fig. 11). Furthermore, viewed from the axial direction of the first swing arm axis A1, in the axial direction D2 of the seat tube 2a the position of the cable guide section 440 in the first state is lower than the position of the cable guide section 440 in the second state.

[0086] In the illustrated embodiment, as shown in Fig. As can be seen in Figure 12, the rope guide 438 comprises a first side S41 and a second side S42 opposite the first side S41. The second orientation is one in which the rope guide 438 is reversed such that the positions of the first side S41 and the second side S42 are exchanged with respect to the first link 16. In the first state, the first side S41 is opposite the first link 16 with respect to the second side S42 ( Fig. 10). In the second state, the second side S42 is opposite the first member 16 with respect to the first side S41 ( Fig. 11).

[0087] As in the Fig. 10 and Fig. As can be seen in Figure 11, the cable guide 438 between the first alignment and the second alignment is shown with respect to the reference line RL1, viewed from the axial direction of the first swing axis A1 (a direction perpendicular to the paper surface of the Fig. 10 and Fig. 11), reversed. That is, the reference line RL1 is an axis of symmetry of the first and second orientations of the cable guide 438. The cable guide 438 can also be reversed between the first and second orientations with respect to a line other than the reference line RL1 (e.g., a line that is essentially perpendicular to the first swing axis A1).

[0088] As in the Fig. 10 and Fig. As shown in Figure 12, the cable guide 438 includes an engagement opening 458. In the first state, the mounting base section 52 is positioned in the engagement opening 458. In the first state, the cable guide 438 is positioned relative to the first link 16 by the mounting base section 52 and the engagement opening 458. In the first state, the mounting base section 52 is configured to prevent movement of the cable guide 438 relative to the first link 16.

[0089] As in the Fig. 11 and Fig. As can be seen in Figure 12, the mounting base section 52 is positioned in the engagement opening 458 in the second state. In the second state, the cable guide 438 is positioned relative to the first link 16 by the mounting base section 52 and the engagement opening 458. In the second state, the mounting base section 52 is configured to prevent movement of the cable guide 438 relative to the first link 16.

[0090] As in Fig. As can be seen in Figure 12, the cable guide 438 includes a joint bore 460 and a fastening bore 462. The first connecting pin 22 runs through the joint bore 460. In the first state, the fastening screw 66 runs through the fastening bore 462 ( Fig. 10). In the second state, the fastening screw 66 passes through the fastening bore 462 ( Fig. 11). By removing the retaining ring 64 and the fastening screw 66, the cable guide 438 can be detached from the first link 16 and moved to a position different from the first orientation ( Fig. 10) and the second alignment ( Fig. 11) be attached to the first link 16.

[0091] As in Fig. As can be seen in Figure 12, even if the cable guide 438 is attached to the rear of the first link 16 in the axial direction of the first swing axis A1, the cable guide 438 can also be attached to the front of the first link 16 or the central section of the first link 16 in the axial direction of the first swing axis A1. Even if the position of the cable guide 438 in the first state ( Fig. 10) with respect to the first link 16 is essentially the same as the position of the rope guide 438 in the second state ( Fig. 11) The position of the rope guide 438 in the first state, relative to the first link 16, can also differ from the position of the rope guide 438 in the second state. For example, in the first state, the rope guide 438 can be arranged on one side of the front and the back of the first link 16, and in the second state, the rope guide 438 can be arranged on the other side of the front and the back of the first link 16. Furthermore, the rope guide 438 can be attached to the second link 18.

[0092] The bicycle derailleur 410 can achieve essentially the same advantageous effect as the bicycle derailleur 10 according to the first embodiment.

[0093] Below is a bicycle derailleur 510 according to a fifth embodiment with reference to the Fig. 13 and Fig. The bicycle derailleur 510 has the same configuration as the bicycle derailleur 10, except for the cable guide section. Therefore, elements with essentially the same function as those in the above embodiments are numbered the same and, for the sake of brevity, are not described and / or illustrated again in detail.

[0094] As in the Fig. 13 and Fig. As shown in Figure 14, the bicycle derailleur 510 includes a cable guide 538, which comprises a cable guide section 540. Unlike the cable guide section 40 according to the first embodiment, the cable guide section 540 includes a guide groove 570 through which the shift cable 5 is to run. The cable guide section 540 is configured such that it can absorb the upward tensile force F1 exerted on the shift cable 5 via the guide groove 570. The design of the cable guide section 540 is not limited to the illustrated embodiment. The cable guide section 540 can, as required and / or desired, include a guide bore and a guide groove. The guide groove 570 can be applied to the further cable guide 44 according to the first embodiment instead of the further guide bore 48 ( Fig. 2) Furthermore, the guide groove 570 can be used instead of the guide bores on the cable guides according to the first to fourth embodiments. Since the cable guide 538 has the same construction as the cable guide 40 according to the first embodiment, except for the cable guide section 540, it is not described in detail here for the sake of brevity.

[0095] The bicycle derailleur 510 can achieve essentially the same advantageous effect as the bicycle derailleur 10 according to the first embodiment.

[0096] Below is a bicycle derailleur 610 according to a sixth embodiment with reference to the Fig. 15, Fig. 16 to Fig. The bicycle derailleur 610 has the same configuration as the bicycle derailleur 410, except for the cable guide section. Therefore, elements with essentially the same function as those in the above embodiments are numbered the same and, for the sake of brevity, are not described and / or illustrated again in detail.

[0097] As in the Fig. 15, Fig. 16 to Fig. As shown in Figure 17, the bicycle derailleur 610 includes a cable guide 638, which comprises a top-pull cable guide section 640 and a bottom-pull cable guide section 641. Unlike the cable guide 438 according to the fourth embodiment, at least one of the top-pull cable guide section 640 and the bottom-pull cable guide section 641 includes a guide groove through which the shift cable 5 is to run. In the illustrated embodiment, the top-pull cable guide section 640 includes a guide groove 642 through which the shift cable 5 is to run. The bottom-pull cable guide section 641 includes a guide groove 643 through which the shift cable 5 is to run. Since the rope guide 638 has the same construction as the rope guide 438 according to the fourth embodiment, except for the top-pull rope guide section 440 and the bottom-pull rope guide section 441, it is not described in detail here for reasons of brevity.

[0098] As in Fig. As can be seen in Figure 15, the top-pull cable guide section 640 is configured to absorb the upward pulling force F1 exerted on the shift cable 5 via the guide groove 642. As shown in Fig. As shown in Figure 16, the bottom-pull cable guide section 641 is configured to receive the downward pulling force F2 exerted on the shift cable 5 via the guide groove 643. At least one of the top-pull cable guide section 640 and the bottom-pull cable guide section 641 can include a guide bore and a guide groove as required and / or desired.

[0099] The bicycle derailleur 610 can achieve essentially the same advantageous effect as the bicycle derailleur 10 according to the first embodiment.

[0100] Those skilled in the art of bicycles will understand from the present disclosure that the above embodiments can be at least partially combined. Furthermore, even if the cable guide is integrally provided as a single unitary component according to the above embodiments, these cable guides can, as required and / or desired, also comprise several parts.

[0101] The term "comprehensive" and its derivatives, as used herein, are intended to be open terms that specify the presence of the listed features, elements, components, groups, integers, and / or steps, but do not exclude the presence of other unlisted features, elements, components, groups, integers, and / or steps. This concept also applies to words of similar meaning, such as the expressions "exhibit," "contain," and their derivatives.

[0102] The terms “component”, “area”, “section”, “part”, “element”, “body” and “construction” can have the dual meaning of one part or several parts when used in the singular.

[0103] The ordinal numbers cited in the present application, such as "first" or "second," are merely descriptive and have no other meaning, such as indicating a specific order or the like. Moreover, for example, the expression "first element" does not in itself imply the existence of a "second element," and the expression "second element" does not in itself imply the existence of a "first element."

[0104] The expression “two” or “pair of”, as used herein, may include a configuration in which two elements have different shapes or constructions, in addition to a configuration in which the two elements have the same shape or construction.

[0105] Finally, by expressions of such degree as "essentially", "about" and "approximately", as used herein, a reasonable degree of deviation from the modified expression is to be understood such that the final result is not significantly altered.

[0106] It is obvious that, in light of the above teachings, numerous modifications and variations of the present invention are possible. It is therefore understood that, within the scope of the appended claims, the invention can also be implemented differently than specifically described herein.
