Description

Technical Field

[0001] This invention relates to an operating device for a human-powered vehicle. Prior Technology

[0002] A human-powered vehicle includes an operating unit. The operating unit includes a base component and a user control component. The user control component is movably connected to the base component. The operating unit is configured to operate a component via movement of the user control component. For example, the operating unit includes a hydraulic structure. The hydraulic structure has a cylinder and a piston component movably disposed in the cylinder. The user control component is operatively coupled to the piston component using a coupling component such as a pin. The coupling component is typically disposed in the base component to restrict the entry of a foreign material into the space surrounding the coupling component. Preferably, this improves the ease of assembling the coupling component to the user control component and the piston component while restricting the entry of a foreign material into the space surrounding the coupling component. Summary of the Invention

The base member is configured to be mounted to the manually operated vehicle. The base member includes a cylinder bore, a first through-hole, and a second through-hole. The piston is movably disposed in the cylinder bore. The operating member is movably coupled to the base member. The intermediate member is configured to couple the operating member to the piston so that the piston moves relative to the base member as the operating member moves. The coupling pin is configured to couple the intermediate member to the piston. The coupling pin has a pin axis and extends along the pin axis. The first through-hole extends in a first direction defined by the pin axis. The second through-hole extends in a second direction not parallel to the first direction. The cover is configured to be attached to the base member to at least partially cover each of the first and second through-holes. The cover is separated from the base member as a separate member.

[0004] In the operating device according to the first embodiment, the first through-hole allows the coupling pin to be inserted into the base member. Therefore, the intermediate member can be coupled to the piston using the coupling pin inserted through the first through-hole. After the intermediate member is coupled to the piston using the coupling pin, the second through-hole allows a component, such as a pin, to be attached to the coupling pin and / or a location of the coupling pin.

[0078] The embodiments will now be described with reference to the accompanying drawings, wherein the same element numbers in the various figures represent corresponding or identical elements.

[0079] Referring to Figure 1, an operating device 10 for a manually driven vehicle 2 includes a base member 12. The base member 12 is configured to be mounted to the manually driven vehicle 2. The operating device 10 is configured to be connected to an operating device 4 via a hydraulic hose 6.

[0080] In this embodiment, the base member 12 is configured to be mounted to a vehicle body 2A of the human-powered vehicle 2. The base member 12 is configured to be a tubular portion 2B (e.g., a handlebar) mounted to the vehicle body 2A of the human-powered vehicle 2. The tubular portion 2B has a longitudinal central axis 2C. The tubular portion 2B extends along the longitudinal central axis 2C. However, if needed and / or required, the base member 12 may be mounted to other parts of the human-powered vehicle 2.

[0081] In this application, a human-powered vehicle is a vehicle that is propelled by the power of at least one person, including the user riding the vehicle (i.e., the rider). Human-powered vehicles include various types of bicycles, such as a mountain bike, a road bike, a city bike, a cargo bike, a hand-cranked bicycle, and a recumbent bicycle. Furthermore, human-powered vehicles include electric bicycles (E-bikes). Electric bicycles include electric-assisted bicycles configured to use an electric motor to assist in propelling the vehicle. However, the total number of wheels in a human-powered vehicle is not limited to two. For example, a human-powered vehicle may have one wheel or three or more wheels. In particular, human-powered vehicles do not include vehicles powered solely by an internal combustion engine. Generally, light road vehicles, including those that do not require a driver's license for public roads, are assumed to be human-powered vehicles.

[0082] In this application, the following directional terms, "before," "after," "forward," "backward," "left," "right," "lateral," "upward," and "downward," as well as any other similar directional terms, represent the direction determined by the user (e.g., the rider) sitting in a standard user position within the human-powered vehicle 2 (e.g., on a cushion or seat), facing a handlebar or steering wheel. Therefore, these terms used to describe the operating device 10 or other elements should be interpreted relative to a human-powered vehicle 2 equipped with the operating device 10, such as when used in an upright riding position on a horizontal surface.

[0083] In this embodiment, the operating device 10 is a right-hand operating device, configured to be operated by a user's right hand. However, if needed and / or required, the structure of the operating device 10 can be implemented as a left-hand operating device.

The operating member 14 is pivotally coupled to the base member 12 about a pivot axis A1 between the stationary position P11 and the operating position P12.

[0085] In this application, the term "resting position" is used herein to mean a position in which a movable part, such as operating member 14, remains stationary and is not operated by the user. The term "operating position" is used herein to mean a position in which the movable part has been operated by the user to perform operation of a bicycle assembly, such as operating device 4.

The operating member 14 is pivotally coupled to the base body 16 via a pivot axis A1 between a rest position P11 and an operating position P12. The operating device 10 includes a pivot shaft 17. The pivot shaft 17 pivotally couples the operating member 14 to the base member 12 via a pivot axis A1. The pivot shaft 17 pivotally couples the operating member 14 to the base body 16 via a pivot axis A1.

[0087] The base member 12 includes a mounting portion 18. The mounting portion 18 defines a mounting axis A2 and is configured to couple the mounting portion 18 to the tubular portion 2B of the manually driven vehicle 2. The mounting portion 18 includes a mounting opening 18A, through which the tubular portion 2B of the manually driven vehicle 2 extends. The mounting axis A2 extends along a longitudinal central axis 2C of the tubular portion 2B in the state where the base body 16 is coupled to the tubular portion 2B of the manually driven vehicle 2 by the mounting portion 18.

The hydraulic hose 6 is detachably and reattachably connected to the hose connection hole 27B. Therefore, hydraulic pressure is supplied from the first cylinder chamber 24 to the operating device 4 via channel 27A, hose connection hole 27B, and hydraulic hose 6.

[0092] As shown in Figure 5, the cylinder bore 20 includes an inner peripheral surface 20B. The piston 22 includes a piston body 22A and a sealing member 22B attached to the piston body 22A. The sealing member 22B slidably contacts the inner peripheral surface 20B to separate the first cylinder chamber 24 from the second cylinder chamber 26. The sealing member 22B is manufactured using a non-metallic material process. The sealing member 22B is manufactured using a rubber process. In this embodiment, the piston 22 does not have an additional sealing member separated from the sealing member 22B. However, if needed and / or required, the piston 22 may include an additional sealing member separated from the sealing member 22B.

The piston 22 is separated from the cylinder head 28 to define a second cylinder chamber 26 between the piston 22 and the cylinder head 28 in the initial state when the piston 22 is in the initial position P21.

[0094] In this embodiment, piston 22 is configured to be pulled from initial position P21 to actuated position P22. Piston 22 is also configured to be pulled from initial position P21 to actuated position P22 by means of actuation member 14.

The pin retainer 58 is configured to couple to a second end 52B of the coupling pin 52 to secure the coupling pin 52 relative to at least one of the intermediate member 32 and the piston 22. The pin retainer 58 is a separate component separate from the coupling pin 52. In this embodiment, the pin retainer 58 is configured to couple to the second end 52B of the coupling pin 52 to secure the coupling pin 52 relative to the intermediate member 32 and the piston 22. The pin retainer 58 and the limiting portion 56 are configured to restrict the movement of the coupling pin 52 relative to the intermediate member 32 and the piston 22 along the pin axis A5.

The cover 60 is configured to be detachably and reattached to the base member 12. The cover 60 is configured to be detachably attached to the base body 16.

[0108] As used herein, the terms "detachable" and "reattachable" include configurations in which components can be repeatedly detached from and attached to another component without material damage.

[0109] As shown in Figure 10, the base member 12 includes a first through-hole 62 and a second through-hole 64. As shown in Figures 8 and 9, the cover 60 is configured to attach to the base member 12 to at least partially cover each of the first through-hole 62 and the second through-hole 64. In this embodiment, the cover 60 is configured to attach to the base member 12 to completely cover each of the first through-hole 62 and the second through-hole 64. However, if desired and / or required, the cover 60 is configured to attach to the base member 12 to partially cover each of the first through-hole 62 and the second through-hole 64.

[0110] As shown in Figure 8, the first through hole 62 extends in a first direction D11 defined along the pin axis A5. The second through hole 64 extends in a second direction D12, which is not parallel to the first direction D11. The second direction D12 intersects the first direction D1. In this embodiment, the second direction D12 is defined along a reference plane RP3 perpendicular to the pin axis A5. The second direction D12 is perpendicular to the first direction D11. However, if necessary and / or required, the second direction D12 may not be perpendicular to the first direction D11.

[0111] As shown in Figures 7 and 9, at least one of the first direction D11 and the second direction D12 is not parallel to the cylinder axis direction D3. In this embodiment, the first direction D11 and the second direction D12 are not parallel to the cylinder axis direction D3. At least one of the first direction D11 and the second direction D12 is perpendicular to the cylinder axis direction D3. However, if necessary and / or required, at least one of the first direction D11 and the second direction D12 may not be perpendicular to the cylinder axis direction D3.

[0112] As shown in Figure 7, the pin axis A5 of the coupling pin 52 extends through the first through hole 62 when the operating member 14 is in the stationary position P11. The pin axis A5 of the coupling pin 52 extends through the first through hole 62 when the piston 22 is in the initial position P21.

[0113] As shown in Figure 11, the pin axis A5 of the coupling pin 52 is offset relative to the first through hole 62 when the operating member 14 is in the operating position P12. The pin axis A5 of the coupling pin 52 is offset relative to the first through hole 62 when the piston 22 is in the actuated position P22.

[0114] As shown in Figures 11 and 12, when the operating member 14 is in the stationary position P11 and the cover 60 is not attached to the base member 12, the coupling pin 52 is visible through the first through hole 62. As shown in Figure 12, when the operating member 14 is in the stationary state and the cover 60 is not attached to the base member 12, the first end 52A of the coupling pin 52 is visible through the first through hole 62. As shown in Figure 13, when the operating member 14 is in the stationary state and the cover 60 is not attached to the base member 12, the second end 52B of the coupling pin 52 is visible through the second through hole 64.

[0115] As shown in Figure 14, the operating device 10 further includes a cover retainer 68. The cover retainer 68 is configured to secure the cover 60 relative to the base member 12. The cover 60 includes an opening 60A. The cover retainer 68 extends through the opening 60A to secure the cover 60 relative to the base member 12. The base member 12 includes a threaded hole 12C. The cover retainer 68 includes a plurality of external threads 68A configured to engage with the threaded hole 12C.

[0116] As shown in Figure 15, the cover 60 includes a cover body 70 and a protrusion 72. The protrusion 72 protrudes from the cover body 70. As shown in Figure 8, the cover body 70 is configured to attach to the base member 12 to at least partially cover the second perforation 64. In a state where the cover 60 is attached to the base member 12, the protrusion 72 is at least partially disposed in the first perforation 62.

[0117] In this embodiment, the cover body 70 is configured to attach to the base member 12 to completely cover the second perforation 64. With the cover body 60 attached to the base member 12, the protrusion 72 is completely disposed in the first perforation 62. However, if needed and / or required, the cover body 70 may be configured to attach to the base member 12 to partially cover the second perforation 64. If needed and / or required, with the cover body 60 attached to the base member 12, the protrusion 72 may be partially disposed in the first perforation 62.

[0118] As shown in Figures 8 and 9, with the operating member 14 in the stationary position P11, the cover 60 is configured to be attached to the base member 12 to at least partially cover the intermediate member 32. In this embodiment, with the operating member 14 in the stationary position P11, the cover 60 is configured to be attached to the base member 12 to completely cover the intermediate member 32. However, if needed and / or required, with the operating member 14 in the stationary position P11, the cover 60 may be configured to be attached to the base member 12 to partially cover the intermediate member 32.

[0119] As shown in Figures 6 and 15, when the operating member 14 is in the operating position P12, the intermediate member 32 is at least partially disposed outside the space S defined by the cover 60. In this embodiment, when the operating member 14 is in the operating position P12, the intermediate member 32 is partially disposed outside the space S defined by the cover 60. However, if necessary and / or required, when the operating member 14 is in the operating position P12, the intermediate member 32 is completely disposed outside the space S defined by the cover 60.

[0120] As shown in Figure 3, the operating component 14 includes an operating lever 74 and a lever adjustment structure 76. The operating lever 74 is pivotally coupled to the base component 12 about a pivot axis A1. The operating lever 74 is pivotable relative to the base component 12 about the pivot axis A1 between a rest position P11 and an operating position P12. The lever adjustment structure 76 is configured to change the rest position P11 of the operating lever 74 relative to the base component 12 about the pivot axis A1.

[0121] As shown in Figure 5, the lever adjustment structure 76 includes an adjustment member 78 and a movable member 80. The adjustment member 78 is configured to change the position of the movable member 80 relative to the operating lever 74. The adjustment member 78 is rotatably coupled to the operating lever 74 via an adjustment rotation axis A6. As shown in Figure 9, the adjustment member 78 includes a turntable 81, which is rotatably coupled to the operating lever 74 via the adjustment rotation axis A6. The turntable 81 is manufactured using a non-metallic material process, such as a resin material. However, if desired and / or required, the turntable 81 may be made of materials other than non-metallic materials. If desired and / or required, the adjustment member 78 may include multiple structures other than the turntable 81.

[0122] As shown in Figure 5, the movable member 80 is movably coupled to the operating lever 74. The movable member 80 is movable relative to the operating lever 74 along the adjustment rotation axis A6. The adjusting member 78 is configured to change this position of the movable member 80 relative to the operating lever 74 along the adjustment rotation axis A6. The movable member 80 is in contact with the intermediate member 32. This movement of the movable member 80 relative to the operating lever 74 along the adjustment rotation axis A6 changes the position of the operating lever 74 relative to the intermediate member 32 (e.g., cam 34) about the pivot axis A1.

[0123] Adjusting member 78 includes an adjusting screw hole 82. Movable member 80 includes a plurality of adjusting threads 80A. Movable member 80 extends through adjusting screw hole 82. The adjusting threads 80A of movable member 80 are screwed into adjusting screw hole 82.

[0124] The lever adjustment structure 76 includes a limiting member 84. The limiting member 84 is coupled to the operating lever 74 to restrict the movable member 80 from rotating along the adjustment rotation axis A6, while allowing the movable member 80 to move along the adjustment rotation axis A6.

[0125] The operating lever 74 includes a guide opening 74A. A movable member 80 is movably disposed in the guide opening 74A. The movable member 80 is guided along the adjustment rotation axis A6 via the guide opening 74A.

[0126] Adjusting member 78 adjusts the rotation axis A6 relative to operating lever 74, thus changing the position of movable member 80 relative to operating lever 74 along the adjustment rotation axis A6. This changes the stationary position P11 of operating lever 74 relative to intermediate member 32 about pivot axis A1.

[0127] As shown in Figure 5, the operating device 10 includes a lever biasing member 86. The lever biasing member 86 is configured to bias the operating member 14 relative to the base member 12 toward an operating position P12. The lever biasing member 86 is also configured to bias the operating lever 74 relative to the base member 12 toward an operating position P12 (see, for example, Figure 3). The lever biasing member 86 is mounted on a pivot shaft 17. For example, the lever biasing member 86 includes a torsion spring. One end of the lever biasing member 86 is coupled to the operating lever 74 of the operating member 14. The other end of the lever biasing member 86 is coupled to the base member 12. A piston biasing member 30 is configured to bias the operating member 14 toward a rest position P11 by the biasing force of the lever biasing member 86 against the piston 22 and the intermediate member 32. Therefore, the piston biasing member 30 and the lever biasing member 86 are configured to maintain the contact between the cam surface 34A of the cam 34 and the roller 44 of the cam follower 36, as well as the contact between the cam 34 and the movable member 80 of the lever adjustment structure 76.

[0128] As shown in Figure 17, the operating device 10 includes a piston adjustment structure 90. The piston adjustment structure 90 is configured to change the initial position P21 of the piston 22. The piston adjustment structure 90 includes a cover fixing member 68 and a piston adjustment member 92. The piston adjustment member 92 is movably coupled to the piston 22. The piston adjustment member 92 is movable relative to the piston 22 and the base member 12 along the cylinder axis A3. The piston adjustment member 92 is in contact with the intermediate member 32. As shown in Figures 1 and 17, the piston adjustment member 92 is in contact with the first coupling member 38 and the second coupling member 40.

[0129] As shown in Figure 17, the cover retainer 68 and the piston adjusting member 92 are contactable. The piston biasing member 30 is configured to bias the piston 22 relative to the base member 12 in a first direction of motion D31. The biasing force of the piston biasing member 30 is applied from the piston biasing member 30 to the intermediate member 32 via the piston 22 and the coupling pin 52 in the first direction of motion D31. The cover retainer 68 contacts the piston adjusting member 92 to restrict the piston 22 and the intermediate member 32 from moving relative to the base member 12 in the first direction of motion D31. Rotation of the cover retainer 68 causes the piston adjusting member 92 to move relative to the base member 12 in either the first direction of motion D31 or a second direction of motion D32, where the second direction of motion D32 is the opposite direction of the first direction of motion D31. Therefore, rotation of the cover retainer 68 changes the initial position P21 of the piston 22.

[0130] In this embodiment, the base member 12 is made of a first material. The cover 60 is made of a second material, which is different from the first material. The first material includes a metallic material. The second material includes a non-metallic material. For example, the first material includes aluminum. The second material includes a resin material. The adjustment member 78 is made of a non-metallic material, such as a resin material. However, if needed and / or required, the base member 12 may be made of a material other than a metallic material. If needed and / or required, the cover 60 may be made of a material other than a non-metallic material. If needed and / or required, the adjustment member 78 may be made of a material other than a non-metallic material.

[0132] The cover 104 is attached to the base body 16 to secure the diaphragm 102 between the base body 16 and the cover 106. The base body 16 and the diaphragm 102 define the storage chamber 11 between the base body 16 and the diaphragm 102. The diaphragm 102 is made of a non-metallic material. The diaphragm 102 is made of an elastic material, such as rubber. The diaphragm 102 is deformable to change the volume of the storage chamber 100.

[0133] Storage chamber 100 has a storage axis A7 and extends along the storage axis A7. Storage chamber 100 includes a first storage chamber 100A and a second storage chamber 100B.

[0136] As shown in Figure 19, the base member 12 includes a first connection port 110 configured to connect the cylinder bore 20 to the storage chamber 100. The first connection port 110 is also configured to connect the cylinder bore 20 to the second storage chamber 100B.

In both the initial and actuated states, the first connection port 110 is configured to connect the second cylinder chamber 26 to the second cylinder chamber 100B.

[0137] As shown in Figures 19 and 20, the base member 12 includes a second connection port 112 configured to connect the cylinder bore 20 to the storage chamber 100.

[0138] As shown in Figure 21, the first connection port 110 includes a first end opening 114, which is disposed on the inner circumferential surface 20B of the cylinder bore 20. The first end opening 114 includes a first end 114A and a second end 114B. The second end 114B is furthest from the first end 114A in a circumferential direction D2 relative to the cylinder axis A3. The first end opening 114 includes a third end 114C and a fourth end 114D. The fourth end 114D is furthest from the third end 114C in the cylinder axis direction D3 relative to the cylinder axis A3. The circumferential distance DS1 between the first end 114A and the second end 114B in the circumferential direction D2 is longer than the axial distance DS2 between the third end 114C and the fourth end 114D in the cylinder axis direction D3. For example, the ratio of the axial distance DS2 to the circumferential distance DS1 is 2.25. However, this ratio of the axial distance DS2 to the circumferential distance DS1 is not limited to the above value. If required and / or necessary, the circumferential distance DS1 may be shorter than or equal to the axial distance DS2.

[0139] As shown in Figure 22, the circumferential distance DS1 is shorter than half the circumference H of the inner circumferential surface 20B.

Each of the first hole 118 and the second hole 120 is configured to connect the cylinder bore 20 to the storage chamber 100. In the initial state and in the actuated state, each of the first hole 118 and the second hole 120 is configured to connect the second cylinder chamber 26 to the storage chamber 100. However, if necessary and / or required, in the initial state and in the actuated state, the first connection port 110 may be a single connection hole configured to connect the second cylinder chamber 26 to the storage chamber 100.

[0141] The first bore 118 has a first longitudinal axis LA11 and extends from the cylinder bore 20 toward the storage chamber 100 along the first longitudinal axis LA11. The second bore 120 has a second longitudinal axis LA12 and extends from the cylinder bore 20 toward the storage chamber 100 along the second longitudinal axis LA12. The second longitudinal axis LA12 is offset relative to the first longitudinal axis LA11. The second longitudinal axis LA12 extends along the first longitudinal axis LA11. The second longitudinal axis LA12 extends parallel to the first longitudinal axis LA11.

[0142] As shown in Figure 22, at least one of the first longitudinal axis LA11 and the second longitudinal axis LA12 is offset relative to the cylinder axis A3 of the cylinder bore 20. In this embodiment, the first longitudinal axis LA11 and the second longitudinal axis LA12 are offset relative to the cylinder axis A3 of the cylinder bore 20. The cylinder axis A3 is located between the first longitudinal axis LA11 and the second longitudinal axis LA12, and does not intersect with either the first longitudinal axis LA11 or the second longitudinal axis LA12, as viewed along the cylinder axis A3.

[0146] In this embodiment, each of the first diameter DM11 and the second diameter DM12 is greater than the distance DS3. The first diameter DM11 is equal to the second diameter DM12. For example, the first diameter DM11 is 2 mm (nanometers). The second diameter DM12 is 2 mm. The distance DS3 is 0.5 mm. The distance DS4, defined between the first vertical axis LA11 and the second vertical axis LA12, is 2.5 mm. However, the first diameter DM11, the second diameter DM12, the distance DS3, and the distance DS4 are not limited to the above values. The relationship between the first diameter DM11, the second diameter DM12, the distance DS3, and the distance DS4 is not limited to the above relationship. If necessary and / or required, at least one of the first diameter DM11 and the second diameter DM12 may be less than or equal to the distance DS3.
