Description

Technical Field

[0001] This disclosure relates to the field of wire control technology, and more particularly to a rotary wire control device assembled on the handlebars of a bicycle. It drives the lifting valve of the bicycle seat post through a rotating mechanism, thereby controlling the lifting valve in a concealed manner. Background Technology

[0002] To adjust the height of bicycle saddles, adjustable seatposts have been developed. Currently, the simplest method is to use a quick-release mechanism to secure the seatpost. When height adjustment is needed, the quick-release handle is released, allowing the inner tube of the seatpost to be pulled up or down, thus changing the seatpost's height. Alternatively, a cable-operated or electronic control device can be used to control the seatpost's pneumatic or hydraulic valve. When the valve is open, downward pressure is applied to the saddle to lower the seatpost or automatically raise it back to its original height.

[0003] Patent publication number TWM558744U discloses a switch handle for adjusting the seatpost height of a curved handlebar. The switch handle includes a paddle with a first actuation segment and a second actuation segment, allowing the rider to pull the control cable and adjust the seatpost height regardless of riding position. However, the first and second actuation segments of this curved handlebar have an outward-protruding structure, making the movement of the first and second actuation segments more noticeable when manipulated with fingers. In competition, opponents may detect changes in tactical strategy through the rider's hand movements, making it easier for them to react accordingly.

[0004] Patent publication number TWM650674U discloses a highly discreet cable control device, which includes a handlebar grip ring and a rotating ring. The rotating ring pulls the second cable of the cable unit along with the first cable of the cable unit. This cable control device of the previous patent is highly discreet; when used on bicycle handlebars, it has no protruding levers and can directly control the cable unit by rotation, reducing the range of hand movements.

[0005] However, there is still room for improvement in the smoothness of the rotating mechanism's operation. Therefore, the inventors have been considering how to provide a more smoothly operating remote control that allows riders to more easily rotate it to increase the speed of changing seat height. Summary of the Invention

[0006] Given the numerous shortcomings of existing bicycle cable control devices, the main objective of this invention is to provide a rotary cable control device that can be directly mounted on the handlebars of a bicycle, using a rotating mechanism to control the cable, allowing the rider to easily and quickly adjust the saddle.

[0007] To achieve the aforementioned main objectives, the present invention provides a rotary wire-controlled device, comprising a mounting base, a guide member, a rotating ring, and a cable. The mounting base has a shaft hole. The guide member is disposed on the mounting base and has a first guide wheel disposed on one side of the mounting base. The rotating ring is sleeved on the mounting base and is rotatable relative to the mounting base. The cable passes through the mounting base and is arranged along the guide member to form a first bend, the first bend of the cable abutting against the outer peripheral surface of the first guide wheel, and one end of the cable is fixed to the rotating ring. When the rotating ring rotates relative to the mounting base, the cable is simultaneously pulled.

[0008] With the above-mentioned technical features, the rotary cable control device is installed on the bicycle handlebars through the shaft hole of the mounting base. The rider then controls the lifting valve of the bicycle seat post by operating the rotary ring. When the rotary ring is rotated in one direction, the entire cable is pulled by the rotary ring, which drives the control component connected to the other end of the cable to control the opening and closing of the lifting valve. In this way, the seat height of the bicycle can be quickly and smoothly adjusted to meet different riding needs.

[0009] Optionally, the mounting base includes a top cover and a ring seat connected to the top cover, with one end of the rotating ring engaged between the top cover and the ring seat. Therefore, the top cover and the ring seat together engage the rotating ring, so that the rotating ring can be securely fixed and will not detach from the mounting base during use.

[0010] Optionally, the top cover has a cable outlet hole, with the cable arranged along the outer edge of the mounting base and extending out of the outlet hole after passing through the mounting base. Therefore, depending on the cable's position, when the cable is pulled, it follows a specific path and controls the lifting valve body inside the bicycle's operating tube from the end that passes through the outlet hole. Its direction of action is simple, making operation smoother.

[0011] Optionally, the mounting base has a first clamping hole penetrating the inner and outer surfaces of the mounting base and a clamping plate disposed on the inner surface of the mounting base; the rotating ring has a second clamping hole penetrating the inner and outer surfaces of the rotating ring, and a clamping member passes through the second clamping hole and the first clamping hole, with one end of the clamping member fixed to the clamping plate. Therefore, when the rotating remote control is mounted on the handlebar through the shaft hole of the mounting base, the clamping member can push against the clamping plate, causing the clamping plate to abut against and clamp against the handlebar, increasing the firmness of the rotating remote control fixed to the handlebar.

[0012] Optionally, the first guide wheel includes a first wheel portion and a first wheel axle passing through the first wheel portion. The first wheel axle fixes the first guide wheel to one side of the mounting base, and the first wheel portion can rotate relative to the first wheel axle. Therefore, the first guide wheel rotates with the first wheel portion, which can reduce the frictional force when the cable is displaced, thereby assisting the cable in displacement and making the cable move more smoothly.

[0013] Optionally, the guide includes a second guide wheel housed in a mounting base. The cable is arranged along the second guide wheel to form a second bend, with the second bend abutting against the outer circumferential surface of the second guide wheel. Therefore, the path of the cable being pulled is restricted by the second guide wheel, allowing the cable to pass through the mounting base, and the wheel-shaped shape of the second guide wheel makes it easier and smoother to pull the cable.

[0014] Optionally, the second guide wheel includes a second wheel portion, a bearing fitted onto the wheel portion, and a second wheel axle passing through the wheel portion and the bearing. The second wheel axle fixes the second guide wheel in the mounting base, while the second wheel portion can rotate relative to the second wheel axle. Therefore, the second guide wheel rotates with the second wheel portion, and the bearing reduces the resistance when the second wheel portion rotates. The second wheel portion and the bearing can then assist the cable in displacement, making the cable operate more smoothly.

[0015] Optionally, the rotating ring has a line positioning portion formed on its inner surface, a through hole formed at one end of the line positioning portion, and a positioning member disposed within the line positioning portion. The cable passes through the through hole and is pressed by the positioning member. Therefore, the rotating ring fixes the cable by the positioning member within the line positioning portion, so that when the cable is driven by the rotating ring, it cannot easily detach from the line positioning portion.

[0016] Optionally, the line positioning portion of the rotating ring is formed by protrusion from the inner surface, while a recessed portion is formed on the outer surface of the mounting base corresponding to the line positioning portion. Therefore, when the rotating ring rotates relative to the mounting base, the line positioning portion will displace along the recessed portion, and when the line positioning portion displaces to both ends of the recessed portion, it indicates that the rotating ring has reached its limit position of rotation, thus achieving the effect of limiting the rotation.

[0017] Optionally, it also includes a rubber collar, which is fitted and fixed to the rotating ring, and the rotating ring is driven by the rubber collar. Therefore, the rubber collar provides a slight friction with the rubber material, so that the rider can get a better operating feel when operating the rotating remote control with his fingers.

[0064] Please refer to Figures 1 to 3 The rotary wire control device 10 of the present invention mainly includes a mounting base 20, a guide 30, a rotating ring 40 and a cable 50.

[0065] Mounting base 20 has a shaft hole 21, a first clamping hole 22, and a clamping plate 23. The shaft hole 21 is formed in the center of the mounting base 20 and allows the handlebar 60 of a bicycle to pass through so that the rotating remote control 10 can be installed on the handlebar 60. The structure of the mounting base 20 can be divided into a top cover 24 and a ring seat 25. The top cover 24 is fixed to the top side of the ring seat 25 with screws 26 or bolts. The top cover 24 has an extension 241 and a cable outlet hole 242 formed in the extension 241. The cable outlet hole 242 passes through the upper and lower sides of the top cover 24, and an arched groove 243 is formed on the top cover 24 adjacent to the cable outlet hole 242. The ring seat 25 has a through hole 251 between its inner and outer sides. The through hole 251 also passes through the upper and lower sides of the ring seat 25. When the top cover 24 and the ring seat 25 are combined, the arched groove 243 will be located on the top side of the through hole 251 to form an accommodating space. The first clamping hole 22 is located on the ring seat 25 of the mounting base 20 near the through hole 251, and it penetrates the inner and outer surfaces of the mounting base 20, while the clamping piece 23 is located on the inner surface of the mounting base 20.

[0066] The guide member 30 can be divided into a first guide wheel 31 and a second guide wheel 32. The guide member 30 has a circular shape, allowing the displacement path of the cable 50 to be arc-shaped, which can prevent the cable 50 from being damaged due to excessive bending and provide a smoother displacement of the cable 50. The first guide wheel 31 includes a first wheel portion 311 and a first wheel axle 312 passing through the first wheel portion 311. The first wheel axle 312 fixes the first guide wheel 31 to the bottom side of the mounting base 20. The first wheel portion 311 can rotate relative to the first wheel axle 312, and the first guide wheel 31 protrudes outward from the bottom side of the mounting base 20, such as... Figure 4 As shown. The second guide wheel 32 includes a second wheel portion 321, a bearing 322 sleeved on the wheel portion, and a second wheel axle 323 passing through the wheel portion and the bearing 322. The second guide wheel 32 is fixed in the mounting base 20 by the second wheel axle 323. The second wheel portion 321 can rotate relative to the second wheel axle 323, and the second guide wheel 32 is accommodated in the receiving space formed by the upper cover 24 and the ring seat 25 of the mounting base 20, as shown. Figure 5 As shown.

[0067] The rotating ring 40 has a second clamping hole 41, a first-line positioning part 42, a through hole 43 and a positioning element 44. The rotating ring 40 has a ring-shaped shape. In actual assembly, the rotating ring 40 is first fitted onto the ring seat 25 of the mounting base 20, and then the upper cover 24 is fixed to the ring seat 25. The top of the rotating ring 40 is then stuck between the upper cover 24 and the ring seat 25. The second clamping hole 41 of the rotating ring 40 penetrates both the inner and outer surfaces of the rotating ring 40. When the mounting base 20 is fitted onto the rotating ring 40, the second clamping hole 41 is connected to the first clamping hole 22, allowing a clamping member 70 to sequentially pass through the second clamping hole 41 and the first clamping hole 22. One end of the clamping member 70 is fixed to the clamping plate 23, and by locking the clamping member 70, it pushes the clamping plate 23, causing the clamping plate 23 to abut against and clamp against the handlebar 60, thereby increasing the firmness of the rotating remote control 10 fixed to the handlebar 60. When locked, the clamping member 70 will be completely submerged in the first clamping hole 22 and will not be located in the second clamping hole 41. Figure 6 As shown, the rotating ring 40 can still rotate relative to the mounting base 20. Please refer to... Figure 7 The line positioning part 42 is disposed on the inner surface of the rotating ring 40. It protrudes from the inner surface of the rotating ring 40 to form a cylindrical shape and has an opening on the top side. Corresponding to the protruding structure of the line positioning part 42, a recess 27 is also formed on the outer side of the mounting base 20. The through hole 43 of the rotating ring 40 is formed at the bottom end of the line positioning part 42 and passes through the left and right sides of the line positioning part 42. The positioning member 44 can be, for example, a screw, which is inserted through the opening of the line positioning part 42 and disposed inside the line positioning part 42.

[0068] During assembly, the cable 50 first passes through the through hole 43 of the line positioning part 42 of the rotating ring 40, then exits from the inner surface of the rotating ring 40 to the outside, and winds along the outer shape of the rotating ring 40 before passing back into the inner surface. At this time, the cable 50 winds to the guide member 30 on the bottom side of the mounting base 20, allowing the cable 50 to wind along the outer peripheral surface of the first wheel part 311 of the first guide wheel 31 of the guide member 30. The cable 50 forms a first bent section 51 in accordance with the shape of the first wheel part 311. The inner side of the first bent section 51 is adjacent to the first wheel part 311. The cable 50 is inserted through the through hole 251 of the ring seat 25 of the mounting base 20, allowing it to wind along the outer circumference of the second wheel portion 321 of the second guide wheel 32 of the guide member 30. The cable 50 forms a second bent section 52 in accordance with the shape of the second wheel portion 321. The inner side of the second bent section 52 abuts against the second wheel portion 321. However, the first bent section 51 and the second bent section 52 will be formed at different positions on the cable 50 as the cable 50 is displaced, and do not refer to a fixed section on the cable 50. Finally, it passes through the cable outlet hole 242 of the top cover 24 and connects to the control component of the lifting valve body that controls the bicycle seat post. The cable 50 located in the line positioning part 42 is tightened by the positioning member 44, fixing one end of the cable 50 to the bottom end of the line positioning part 42. Figure 8As shown. However, this embodiment does not limit the winding path of the cable 50. If there is enough space between the rotating ring 40 and the mounting base 20, the cable 50 can be directly wound around the guide member 30 on the bottom side of the mounting base 20 on the inner surface of the rotating ring 40. The path sequence can also be that the cable 50 is first inserted through the outlet hole 242 of the upper base, and then the cable 50 is set in the corresponding position in sequence.

[0069] In addition, the rotating wire control device 10 of the present invention also includes a rubber collar 80, which is sleeved and fixed to the rotating ring 40. Since the rubber collar 80 is made of rubber, it can provide a slight friction force, and the rider can get a better feel when applying force to the rubber collar 80 with his fingers, making the rotating ring 40 easier to operate.

[0070] To adjust the bicycle seat height, the rider holds the rubber collar 80 of the rotary remote control 10. Because the cable positioning portion 42 of the rotating collar 40 and the recessed portion 27 of the mounting base 20 form corresponding shapes, the rotary remote control 10 provides rotation in only one direction. The position of the rotating collar 40 is as follows: Figure 9 Move to Figure 10 When the rider applies rotational force to the rubber collar 80 in that direction, the rotating ring 40 is simultaneously rotated, changing the position of the cable 50 fixed to the cable positioning part 42. This causes the entire cable 50 to rotate, and the first wheel portion 311 of the first guide wheel 31 and the second wheel portion 321 of the second guide wheel 32 of the guide member 30 will rotate due to the cable 50 being pulled, making the cable 50 move more easily and smoothly. At this time, one end of the cable 50 connected to the control component of the lifting valve body is pulled downward, driving the lifting valve body to the open state, thus adjusting the seat height.

[0071] When the seat cushion is adjusted to the appropriate height, the rotational force applied to the rubber collar 80 is released. At this time, the lifting valve body reverses and becomes closed, and the cable 50 at this end is pulled upward and reset. The resetting force of the cable 50 can drive the rotating ring 40 to rotate in the opposite direction. The position of the rotating ring 40 is as follows: Figure 10 Move to Figure 9 During the reset process, the first wheel portion 311 of the first guide wheel 31 and the second wheel portion 321 of the second guide wheel 32 of the guide member 30 will both rotate, improving the smoothness and speed of the reverse rotation of the rotating ring 40, thus completing the adjustment of the seat height.

[0072] In summary, the rotary wire control device 10 provided by the present invention has at least the following advantages compared with the prior art:

[0073] 1. The rotary wire control device 10 of the present invention fixes one end of the cable 50 to the rotating ring 40, so that when the rotating ring 40 rotates relative to the mounting base 20, the entire cable 50 is driven by the rotating ring 40. The cable 50 can move smoothly along the guide member 30, and the control component connected to the other end of the cable 50 can smoothly control the opening and closing of the lifting valve body.

[0074] 2. The rotating wire control device 10 of the present invention mainly consists of a shaft hole 21 of the mounting base 20 for mounting the tube body of the bicycle handlebar 60. The annular shape of the rotating ring 40 ensures that the rotating wire control device 10 does not appear obtrusive when installed on the handlebar 60, providing high concealment without affecting the overall appearance of the bicycle. Furthermore, the rotating wire control device 10 is not easily noticed when it is operated.

[0075] Finally, it must be stated again that the constituent elements disclosed in the foregoing embodiments of the present invention are merely illustrative examples and are not intended to limit the scope of this application. Substitutions or variations of other equivalent elements should also be covered by the claims of this application.
