[0059] <Implementation Method>

[0060] Reference Figures 1 to 9 , a component 20 for a human-powered vehicle of an embodiment is described. A human-powered vehicle is a vehicle having at least one wheel and capable of being driven at least by human-powered driving force. Human-powered vehicles include various bicycles such as mountain bikes, road bikes, city bikes, cargo bikes, push bikes, and recumbent bikes. The number of wheels a human-powered vehicle has is not limited. Human-powered vehicles include, for example, unicycles and vehicles having two or more wheels. Human-powered vehicles are not limited to vehicles that can only be driven by human-powered driving force. Human-powered vehicles include electric bicycles (E-bikes) that are propelled not only by human-powered driving force but also by the driving force of an electric motor. Electric bicycles (E-bikes) include electric-assisted bicycles that are propelled with the assistance of an electric motor. Below, in the embodiment, a human-powered vehicle is described as a bicycle.

[0061] In this specification, the following terms indicating directions, such as "front", "rear", "front", "rearward", "left", "right", "lateral", "above" and "below", and terms indicating any other similar directions, refer to these directions determined with reference to the rider facing the handlebars in a reference position of the human-powered vehicle (for example, on the saddle or seat).

[0062] For example, a human-powered vehicle has wheels, a vehicle body, and a crank. For example, the wheels include a front wheel and a rear wheel. For example, the vehicle body includes a vehicle frame 10. For example, the crank includes: a crankshaft that can rotate relative to the vehicle frame 10; and two crank arms that are provided at each end of the crankshaft in the axial direction. For example, each crank arm is connected to a pedal.

[0063] For example, the rear wheel is driven by the rotation of the crank. For example, the rear wheel is supported by the frame 10. The wheel axle 14 of the rear wheel has a rear wheel center axis C. For example, the crank is connected to the rear wheel through a drive mechanism. For example, the drive mechanism includes a rear sprocket 12 and a chain 16. For example, the drive mechanism includes a plurality of rear sprockets 12.

[0064] For example, the drive mechanism further includes at least one front sprocket connected to the crankshaft. For example, the chain 16 is wound around the front sprocket and the rear sprocket 12. For example, the chain 16 transmits the rotational force of the front sprocket to the rear sprocket 12.

[0065] like Figure 1 As shown, the component 20 for a human-powered vehicle is mounted on the frame 10 of the human-powered vehicle. For example, the component 20 is actuated by the traction of the cable 22. For example, the component 20 includes a base component 24. For example, the base component 24 has a base component body 24A. For example, the base component 24 has a frame mounting portion 24B for mounting on the frame 10 of the human-powered vehicle. For example, the base component 24 is mounted on the frame 10 in a manner that movement relative to the frame 10 is restricted. For example, the base component 24 is composed of a single component. For example, the base component 24 is formed of a single material. For example, the base component 24 is formed of a metal material. For example, the metal material includes aluminum, titanium, or chrome-molybdenum steel. For example, the frame mounting portion 24B is formed integrally with the base component body 24A. For example, the frame mounting portion 24B can also be formed separately from the base component body 24A.

[0066] For example, Figure 1 as well as Figure 8The illustrated assembly 20 includes a movable mechanism 26 that moves relative to the base member 24 by being pulled by the cable 22. For example, the cable 22 includes an inner wire 22A and an outer tube 22B that accommodates the inner wire 22A. The movable mechanism 26 moves relative to the base member 24 by being pulled by the inner wire 22A. For example, one end of the inner wire 22A is mounted on the movable mechanism 26. For example, the other end of the inner wire 22A is mounted on an operating device for actuating the assembly 20. For example, when the assembly 20 is actuated, the movable mechanism 26 moves relative to the base member body 24A due to the pulling of the cable 22. For example, the movable mechanism 26 includes a wire connecting portion 26A connected to the cable 22. For example, the wire connecting portion 26A is connected to one end of the inner wire 22A.

[0067] like Figures 1 to 3 As shown, for example, the component 20 is a derailleur 28. The component 20 may also be a brake device for a human-powered vehicle. For example, the derailleur 28 is a rear derailleur 30. The derailleur 28 may also be a front derailleur. Hereinafter, the component 20 is described as a rear derailleur 30.

[0068] For example, the rear derailleur 30 is configured to be able to change the ratio of the rotation speed of the rear wheel to the rotation speed of the crank, that is, the speed ratio. For example, the rear derailleur 30 is configured to change the speed ratio by relocating the chain 16 from one of the plurality of rear sprockets 12 to another. The user operates the operating device for operating the assembly 20, so that the pulling amount of the inner cable 22A changes. For example, the rear derailleur 30 moves the position of the movable member 32 relative to the plurality of rear sprockets 12 according to the pulling amount of the inner cable 22A. By moving the position of the movable member 32 relative to the plurality of rear sprockets 12, the speed change operation of relocating the chain 16 from one of the plurality of rear sprockets 12 to another is performed.

[0069] like Figure 4 As shown, for example, the rear derailleur 30 includes a base member 24, a movable member 32, a link mechanism 34, and a pulley assembly 36. For example, the movable member 32 and the link mechanism 34 are included in the movable mechanism 26. The base member body 24A is connected to the movable member 32 via the link mechanism 34.

[0070] like Figures 1 to 3 As shown, for example, the frame 10 includes a component mounting member 10A. The component mounting member 10A is a member for mounting the component 20 on the frame 10. For example, the component mounting member 10A is formed separately from the frame 10. For example, the base member 24 is mounted on the frame 10 via the component mounting member 10A, so that the component 20 is mounted on the frame 10. For example, the rear derailleur 30 is mounted on the frame 10 via the component mounting member 10A.

[0071] For example, one end of the assembly mounting member 10A is mounted with the frame mounting portion 24B. For example, the other end of the assembly mounting member 10A is mounted with the frame 10. For example, the other end of the assembly mounting member 10A is mounted to the frame 10 by a bolt. For example, the central axis of the bolt coincides with the rear wheel central axis C of the wheel axle 14 of the rear wheel.

[0072] The frame mounting portion 24B has a mounting surface 24C that is opposite to the assembly mounting member 10A. When the assembly 20 is mounted on the human-powered vehicle, the mounting surface 24C is parallel to the center plane CP along the front-rear direction B1 of the human-powered vehicle. The mounting surface 24C may be in direct contact with the assembly mounting member 10A. For example, a washer may be provided between the mounting surface 24C and the assembly mounting member 10A.

[0073] The assembly mounting member 10A may be omitted. When the assembly mounting member 10A is omitted, the assembly 20 is directly mounted on the vehicle frame 10 via the vehicle frame mounting portion 24B. When the assembly mounting member 10A is omitted, for example, the mounting surface 24C may be in direct contact with the vehicle frame 10. For example, a gasket may be provided between the mounting surface 24C and the vehicle frame 10.

[0074] For example, the movable member 32 is configured to be movable relative to the base member 24. For example, the movable member 32 is mounted on the base member 24 in a manner movable relative to the base member 24. For example, the movable member 32 is configured to move toward the frame 10 and away from the frame 10 when the rear derailleur 30 is mounted on the human-powered vehicle.

[0075] For example, the link mechanism 34 connects the movable member 32 to the base member 24. For example, the link mechanism 34 is connected to the base member body 24A in a manner that can rotate relative to the base member body 24A. For example, the link mechanism 34 includes an inner link member 34A and an outer link member 34B. For example, in a state where the rear derailleur 30 is mounted on the frame 10, the outer link member 34B is arranged at a position farther from the frame 10 than the inner link member 34A.

[0076] For example, the pulley assembly 36 is connected to the movable member 32 in a manner that it can rotate in the circumferential direction of the first rotation axis R1 relative to the movable member 32. For example, the pulley assembly 36 includes at least one pulley 38 having a second rotation axis R2. For example, the pulley assembly 36 includes at least one of the inner guide plate 44 and the outer guide plate 46.

[0077] For example, at least one pulley 38 includes a guide pulley 40 that guides the chain 16. For example, the guide pulley 40 is configured to engage with the chain 16. The guide pulley 40 is mounted on at least one of the inner guide plate 44 and the outer guide plate 46 in a manner that allows rotation around the second rotation axis R2. For example, the second rotation axis R2 is different from the first rotation axis R1.

[0078] For example, the pulley assembly 36 includes a tensioning pulley 42 for maintaining tension on the chain 16. For example, the tensioning pulley 42 is configured to engage with the chain 16. The tensioning pulley 42 is mounted on at least one of the inner guide plate 44 and the outer guide plate 46 in a manner rotatable around the third rotation axis R3. For example, the third rotation axis R3 is different from the first rotation axis R1 and the second rotation axis R2.

[0079] For example, the wire connection portion 26A is attached to the link mechanism 34. For example, the wire connection portion 26A is provided on the inner link member 34A. For example, by changing the pulling amount of the inner wire 22A, the link mechanism 34 rotates relative to the base member 24. For example, by rotating the link mechanism 34 relative to the base member 24, the position of the movable member 32 relative to the plurality of rear sprockets 12 changes. For example, by changing the position of the movable member 32 relative to the plurality of rear sprockets 12, the speed ratio changes.

[0080] like Figures 4 to 9 As shown, for example, the assembly 20 includes a mounting portion 50 and a protection portion 52. For example, the assembly 20 includes a tension adjusting portion 48. For example, the tension adjusting portion 48 adjusts the tension of the cable 22. For example, the tension adjusting portion 48 adjusts the tension of the inner wire 22A. For example, the tension adjusting portion 48 is configured to be operable by a user.

[0081] like Figure 3 As shown, the tension adjustment portion 48 has a first central axis C1 extending along the first axial direction A1. When the component 20 is mounted on the human-powered vehicle, when viewed from a direction parallel to the center plane CP along the front-to-back direction B1 of the human-powered vehicle, for example, the first central axis C1 is configured to be inclined by more than 30 degrees and less than 45 degrees relative to the center plane CP. When the component 20 is mounted on the human-powered vehicle, when viewed from a direction parallel to the center plane CP along the front-to-back direction B1, for example, the first central axis C1 is configured to be inclined by more than 34 degrees and less than 40 degrees relative to the center plane CP. When the component 20 is mounted on the human-powered vehicle, the inclination angle X of the first central axis C1 relative to the center plane CP when viewed from a direction parallel to the center plane CP along the front-to-back direction B1 is, for example, 35.2 degrees.

[0082] like Figure 5As shown, for example, the mounting portion 50 is configured to mount the tension adjusting portion 48. For example, the mounting portion 50 is provided on the base member 24. For example, the mounting portion 50 is formed integrally with the base member 24. For example, the mounting portion 50 is provided on the base member body 24A. For example, the mounting portion 50 extends from the base member body 24A in the first axial direction A1. In the mounted state where the tension adjusting portion 48 is mounted on the mounting portion 50, the central axis of the mounting portion 50 is, for example, consistent with the first central axis C1.

[0083] like Fig. 9 As shown, for example, the mounting portion 50 includes: a first hole 50D for inserting the cable 22; and a first engaging portion 50E disposed in the first hole 50D. For example, the first engaging portion 50E includes an internal thread.

[0084] For example, the tension adjusting portion 48 is mounted on the mounting portion 50. For example, the tension adjusting portion 48 includes: a shaft member 56 for inserting the cable 22; and a second engaging portion 56B provided on an outer surface 56A of the shaft member 56 and engaging with the first engaging portion 50E. For example, the second engaging portion 56B includes an external thread.

[0085] For example, the shaft member 56 includes an insertion hole 56C for inserting the cable 22. For example, the insertion hole 56C includes a first insertion hole 56D and a second insertion hole 56E having a larger diameter than the first insertion hole 56D. The end of the outer tube 22B is inserted into the second insertion hole 56E. The portion of the inner wire 22A protruding from the outer tube 22B is inserted into the first insertion hole 56D. The portion of the inner wire 22A that is closer to the opposite side of the outer tube 22B than the portion arranged in the first insertion hole 56D is inserted into the first hole 50D of the mounting portion 50. The portion of the inner wire 22A that is drawn out from the first hole 50D is connected to the wire connecting portion 26A.

[0086] For example, the tension adjustment portion 48 further includes a tubular member 58 having a second hole 58A in which at least a portion of the shaft member 56 is disposed. For example, the tubular member 58 includes: a first tubular member end 58B; and a second tubular member end 58C, which is disposed at a distance from the first tubular member end 58B in the first axial direction A1. For example, the first tubular member end 58B is located closer to the mounting portion 50 than the second tubular member end 58C in the first axial direction A1.

[0087] For example, the tension adjustment portion 48 further includes a force applying member 60 that applies force to the tubular member 58. For example, the force applying member 60 is disposed in the second hole 58A. For example, the force applying member 60 is disposed between the shaft member 56 and the tubular member 58 in the first axial direction A1. For example, the force applying member 60 applies force to the tubular member 58 toward the mounting portion 50. For example, the force applying member 60 includes a coil spring.

[0088] like Figure 7 As shown, for example, the mounting portion 50 includes a relative portion 50A disposed opposite to the tension adjusting portion 48 in the first axial direction A1 when the tension adjusting portion 48 is mounted on the mounting portion 50. For example, the relative portion 50A includes a first mounting portion end portion 50B. For example, the relative portion 50A is disposed opposite to the first tubular member end portion 58B of the tubular member 58.

[0089] For example, the mounting portion 50 includes: a first mounting portion end portion 50B; and a second mounting portion end portion 50C, which is spaced apart from the first mounting portion end portion 50B in the first axial direction A1. For example, in the mounting state where the tension adjusting portion 48 is mounted on the mounting portion 50, the first mounting portion end portion 50B is located closer to the tension adjusting portion 48 than the second mounting portion end portion 50C. For example, in the mounting state where the tension adjusting portion 48 is mounted on the mounting portion 50, the second mounting portion end portion 50C is located closer to the wire connecting portion 26A of the movable mechanism 26 than the first mounting portion end portion 50B.

[0090] like Fig. 9 As shown, for example, the assembly 20 further has an annular component 54. For example, the annular component 54 protects the mounting portion 50 from being worn by the friction generated by the movement of the cable 22, etc. For example, the mounting portion 50 has a recess 50F. For example, the recess 50F is provided at the second mounting portion end 50C. For example, the recess 50F is provided at the second mounting portion end 50C in a manner recessed from the end surface of the second mounting portion end 50C toward the first axial direction A1. For example, the annular component 54 is configured in the recess 50F. For example, the annular component 54 is pressed into the recess 50F. The annular component 54 can be mounted to the recess 50F by an adhesive or the like. The annular component 54 can be omitted.

[0091] For example, the shaft member 56 includes: a first shaft member end 56F; and a second shaft member end 56G, which is spaced apart from the first shaft member end 56F in the first axial direction A1. For example, in the state where the tension adjusting part 48 is mounted on the mounting part 50, the first shaft member end 56F is located closer to the annular member 54 than the second shaft member end 56G. For example, in the state where the tension adjusting part 48 is mounted on the mounting part 50, the second shaft member end 56G is located on the cylindrical member 58 side.

[0092] For example, the user can adjust the tension of the cable 22 by turning the cylindrical member 58 by hand. For example, the user can change the amount of screwing of the external thread of the second engaging portion 56B relative to the internal thread of the first engaging portion 50E by turning the tension adjusting portion 48 by hand. By changing the amount of screwing of the external thread of the second engaging portion 56B relative to the internal thread of the first engaging portion 50E, the tension of the inner line 22A changes, and thus the tension of the inner line 22A is adjusted. For example, when the cylindrical member 58 rotates in a manner such that the shaft member 56 approaches the annular member 54, the tension of the inner line 22A becomes weaker. For example, when the cylindrical member 58 rotates in a manner such that the shaft member 56 moves away from the annular member 54, the tension of the inner line 22A becomes stronger.

[0093] like Figures 5 to 7 As shown, for example, the protection portion 52 protects the tension adjustment portion 48. For example, the protection portion 52 protects the tension adjustment portion 48 and is formed integrally with the mounting portion 50. In the case where the mounting portion 50 is formed integrally with the base member 24, the protection portion 52 may be formed integrally with the base member 24. For example, the protection portion 52 protects the tension adjustment portion 48 so that the tension adjustment portion 48 does not contact an object outside the human-powered vehicle. For example, the object outside the human-powered vehicle is an obstacle on the road, the ground, and gravel.

[0094] For example, the protection part 52 is formed of metal. The protection part 52 may be formed of resin. For example, in the case where the protection part 52 and the mounting part 50 are formed integrally, the protection part 52 and the mounting part 50 are formed of the same material. For example, the protection part 52 and the mounting part 50 may be formed integrally by at least one of casting and forging. In the case where the protection part 52 and the mounting part 50 are formed integrally and the protection part 52 is formed of resin, the protection part 52 may be formed integrally with the mounting part 50 by insert molding.

[0095] For example, when viewed from the radial direction relative to the first central axis C1, at least a portion of the protection portion 52 is disposed at a position overlapping with at least a portion of the tension adjusting portion 48. For example, at least a portion of the protection portion 52 covers the radially outer side of at least a portion of the tension adjusting portion 48. For example, when viewed from the radial direction relative to the first central axis C1, at least a portion of the protection portion 52 is disposed at a position overlapping with at least a portion of the tubular member 58. For example, in the first axial direction A1, at least a portion of the protection portion 52 is disposed at a position overlapping with at least a portion of the tension adjusting portion 48. For example, in the first axial direction A1, at least a portion of the protection portion 52 is disposed at the same position as at least a portion of the tension adjusting portion 48.

[0096] like Figure 2 as well as Figure 3As shown, for example, when the assembly 20 is mounted on the human-powered vehicle, at least a portion of the protection portion 52 is located farther from the center plane CP along the front-rear direction B1 of the human-powered vehicle than the mounting portion 50 .

[0097] For example, when the assembly 20 is mounted on the human-powered vehicle, the protection portion 52 is located farther from the center plane CP along the front-rear direction B1 of the human-powered vehicle than the wire connection portion 26A. For example, when the assembly 20 is mounted on the human-powered vehicle, the wire connection portion 26A is located closer to the center plane CP than the mounting portion 50 and the protection portion 52. For example, when the assembly 20 is mounted on the human-powered vehicle and the tension adjustment portion 48 is mounted on the mounting portion 50, at least a portion of the tension adjustment portion 48 is located closer to the center plane CP than at least a portion of the protection portion 52.

[0098] For example, the protection portion 52 includes a protrusion 62 configured to protrude radially from the mounting portion 50. For example, the protrusion 62 protrudes from the base member body 24A. Figure 7 as well as Fig. 9 As shown, for example, the protrusion 62 extends from the first center axis C1 toward the radially outer side relative to the first center axis C1 and is inclined relative to the mounting portion 50 as it moves from the first end 62A toward the second end 62B. For example, the protrusion 62 extends linearly in a manner inclined relative to the first center axis C1. For example, the inclination angle of the protrusion 62 relative to the first center axis C1 is greater than 5 degrees and less than 90 degrees. For example, the inclination angle of the protrusion 62 relative to the first center axis C1 is greater than 10 degrees and less than 45 degrees.

[0099] like Figures 7 to 9 As shown, for example, the protrusion 62 includes: a first end 62A, which is continuous with the mounting portion 50; and a second end 62B, which is located on the opposite side of the first end 62A. For example, the second end 62B is formed flat. For example, in the first axial direction A1, the second end 62B is located on the opposite side of the second mounting portion end 50C relative to the first mounting portion end 50B. For example, in the first axial direction A1, the second end 62B is not located between the first mounting portion end 50B and the second mounting portion end 50C. For example, in the first axial direction A1, the second end 62B is located outside the area between the first mounting portion end 50B and the second mounting portion end 50C. For example, the first end 62A is continuous with the opposite portion 50A of the mounting portion 50. For example, the first end 62A is continuous with the first mounting portion end 50B of the tension adjustment portion 48.

[0100] For example, when viewed from the radial direction relative to the first central axis C1, at least a portion of the first end portion 62A is disposed at a position overlapping with the first engaging portion 50E. For example, in the mounted state where the tension adjusting portion 48 is mounted on the mounting portion 50, when viewed from the radial direction relative to the first central axis C1, at least a portion of the first end portion 62A is disposed at a position overlapping with the second engaging portion 56B. For example, in the first axial direction A1, the second end portion 62B is located between the first tubular component end portion 58B and the second tubular component end portion 58C. For example, in the first axial direction A1, the second end portion 62B is located closer to the first tubular component end portion 58B than the second tubular component end portion 58C. For example, in the first axial direction A1, the protrusion amount of the protrusion 62 closer to the second tubular component end portion 58C side than the first mounting portion end portion 50B is shorter than the length of the portion of the mounting portion 50 closer to the second mounting portion end portion 50C side than the first mounting portion end portion 50B.

[0101] For example, the protrusion 62 has a tapered shape that tapers from the first end 62A toward the second end 62B. For example, the protrusion 62 has a tapered shape that tapers from the first end 62A toward the second end 62B in a cross section including the protrusion 62 and the first central axis C1. For example, when viewed from a direction parallel to the first axial direction A1, the protrusion 62 has a tapered shape that tapers from the first end 62A toward the second end 62B.

[0102] like Figure 5 as well as Figure 6 As shown, for example, the first end portion 62A is provided within a range DX of more than 10 degrees and less than 180 degrees in the circumferential direction relative to the first central axis C1 in the mounting portion 50. For example, the second end portion 62B is provided within a range shorter than the range DX in the circumferential direction relative to the first central axis C1 in the mounting portion 50.

[0103] like Figure 5 as well as Figure 6 As shown, for example, the side surface 64 of the protruding portion 62 facing the tension adjusting portion 48 has a shape in which the central portion 64A is recessed along the tension adjusting portion 48. For example, the central portion 64A is the center of the side surface 64 in the circumferential direction relative to the first central axis C1. For example, the side surface 64 has a shape in which the central portion 64A is recessed so as to surround the tension adjusting portion 48. For example, the outer side surface 66 of the protruding portion 62 located on the opposite side of the side surface 64 in the radial direction has a flat shape. The outer side surface 66 may also have a shape in which the central portion is convex in the circumferential direction relative to the first central axis C1.

[0107] The shape and size of the protrusion 62 can be changed as appropriate. For example, the protrusion 62 extends in a curved manner relative to the mounting portion 50 as it moves from the first end portion 62A toward the second end portion 62B and from the first central axis C1 toward the radially outer side relative to the first central axis C1. The protrusion 62 may include: a first portion extending parallel to the first central axis C1 toward the radially outer side relative to the first central axis C1; and a second portion that is continuous with the first portion and extends parallel to the first central axis C1.

[0108] The shape and size of the protection portion 52 are not limited as long as the tension adjustment portion 48 can be protected. The protection portion 52 may be provided over a range of 180 degrees or more and 360 degrees or less in the circumferential direction relative to the first central axis C1 in the mounting portion 50. The protection portion 52 may also be provided intermittently over a range of 180 degrees or more and 360 degrees or less in the circumferential direction relative to the first central axis C1 in the mounting portion 50. Fig.10 The protection portion 52 shown is provided so as to cover the entire circumference of the mounting portion 50 in the circumferential direction relative to the first central axis C1.

[0109] The assembly 20 for a human-powered vehicle is an assembly 20 for a human-powered vehicle that is actuated by the pulling of a cable 22, and includes: a mounting portion 50 configured to mount a tension adjusting portion 48, the tension adjusting portion 48 having a first central axis C1 extending along a first axial direction A1 and used to adjust the tension of the cable 22; and a protecting portion 52 that protects the tension adjusting portion 48 and is formed integrally with the mounting portion 50. When viewed from a radial direction relative to the first central axis C1, as long as at least a portion of the protecting portion 52 is disposed at a position overlapping at least a portion of the tension adjusting portion 48, other structures may be omitted. For example, in this modified example, the assembly 20 may be a brake, an adjustable seat post, or a suspension.

If the assembly 20 is a derailleur 28, other structures may be omitted. For example, in this modified example, the protecting portion 52 may be configured separately from the mounting portion 50 and mounted on the mounting portion 50. For example, in this modified example, the protecting portion 52 may be mounted on the mounting portion 50 by bolts or adhesives.
