Description

Technical Field

[0001] This invention relates to the field of bicycle rim spoke technology, and specifically to a bicycle rim spoke. Background Technology

[0002] One end of the spokes connects to the rim, and the other end connects to the hub. Existing rim spokes are usually made of rigid materials, such as steel spokes. When the tensile force of the spokes approaches the limit of the rigid material, the spokes will deform under a large impact, eventually leading to a weakening of strength and creating potential riding malfunctions. Summary of the Invention

[0003] The purpose of this invention is to provide a bicycle rim spoke that, when the textile fiber spoke rope is subjected to a violent impact under high tension, the flexibility and strength margin of the spoke rope itself can buffer part of the impact force, so that the spoke rope can still maintain its original characteristics under extreme impact force and will not undergo irreversible deformation, thereby reducing the failure rate of riding, ensuring riding safety, and reducing the need for daily wheel maintenance and reducing costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bicycle rim spoke includes a spoke cord and a toothed cap. Both ends of the spoke cord are fixedly fitted with mounting heads. The toothed cap has a through mounting hole and is fixedly fitted onto the mounting head through the mounting hole.

[0006] Preferably, the spokes are made of textile fiber.

[0007] Preferably, the spoke rope is woven from several textile fiber ropes.

[0008] Preferably, the mounting hole is a tapered hole with a smaller inner diameter and a larger outer diameter, and the mounting head is a mounting head with a uniform outer diameter, the outer diameter of the mounting head being adapted to the maximum inner diameter of the mounting hole.

[0009] Preferably, the outer end of the toothed cap has a threaded structure, and the toothed cap is inserted into the spoke hole of the rim or hub and cooperates with the nut to connect the spoke rope to the rim or hub.

[0010] Preferably, the mounting head is provided with a socket hole, and its outer wall is radially provided with a pressing opening that communicates with the socket hole. The end of the spoke rope is inserted into the socket hole, and the pressing opening is formed into a closed pressing structure by adhesive and machine pressing to fix the spoke rope.

[0011] Preferably, both the mounting head and the tooth cap are made of metal.

[0012] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0013] 1. This invention relates to a bicycle rim spoke. In the prior art, spokes are generally made of rigid materials. Rigid spokes have poor cushioning ability when subjected to large impacts, ultimately leading to irreversible deformation. This invention overcomes this technological blind spot by creatively using flexible textile fiber spoke rope as the spoke material. Compared to traditional rigid spokes, which can only withstand a maximum tensile force of 2-3 kN, textile fiber spoke rope can withstand a maximum tensile force of 6-8 kN. Furthermore, while increasing tension and rigidity, textile fiber spoke rope still retains more strength margin. When the textile fiber spoke rope encounters a violent impact under high tension, the flexibility and strength margin of the spoke rope itself cushions part of the impact force, allowing the spoke rope to maintain its original characteristics even under extreme impact, preventing irreversible deformation, reducing riding failure rates, ensuring riding safety, and simultaneously reducing the need for routine wheel maintenance and lowering costs.

[0014] 2. The present invention provides a rim spoke, which is made of textile fiber spoke rope. The rim is lightweight, especially when used with other carbon fiber wheelsets, which improves the user's riding comfort. Compared with traditional rigid spokes, it is more environmentally friendly.

[0015] 3. This invention relates to a bicycle rim spoke. The end of the spoke rope is fixedly inserted into the socket hole of the mounting head by adhesive and machine pressing. The mounting hole on the toothed cap is a tapered hole with a smaller inner diameter and a larger outer diameter. The outer diameter of the mounting head matches the maximum inner diameter of the mounting hole. Before installing the mounting head, the toothed cap is first inserted into the spoke rope. After the mounting head is fixed at the end of the spoke rope, the toothed cap is moved so that its mounting hole tightly engages with the mounting head. Because the outer diameter of the mounting head matches the maximum inner diameter of the mounting hole, the mounting hole gradually becomes smaller during the movement. It undergoes slight deformation due to the pressure of the mounting head, resulting in an increase in the outward pressure on the matching nut. The pressure is greater towards the end of the spoke rope, effectively preventing the nut from loosening and falling off the toothed cap due to spoke rope vibration during riding, thus preventing potential malfunctions. Furthermore, the slight deformation of the mounting head also causes it to press towards the socket hole, further pressing the mounting head tightly against the end of the spoke rope.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] It should be noted that in this invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element of this invention must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0022] Example

[0023] Please refer to Figures 1 to 4 As shown, the present invention discloses a bicycle rim spoke, including a spoke cord 1 and a toothed cap 2. Both ends of the spoke cord 1 are fixedly sleeved with mounting heads 3. The toothed cap 2 is provided with a through mounting hole 21, and the toothed cap 2 is fixedly sleeved on the mounting head 3 through the mounting hole 21.

[0024] The spoke rope 1 is made of textile fiber material. The surface of the spoke rope 1 is cut and polished to make the surface very uniform. Due to the tension of the spoke rope 1 itself, the surface of the spoke rope will not be contaminated with too much dirt.

[0025] The spoke rope 1 adopts a hollow weaving structure and is made of several textile fiber ropes. In this embodiment, the textile fiber material is polyester fiber.

[0026] Both the mounting head 3 and the threaded cap 2 are made of metal. The mounting hole 21 is a tapered hole with a smaller inner diameter and a larger outer diameter. The mounting head 11 is a mounting head with a uniform outer diameter. The outer diameter of the mounting head 3 is matched with the maximum inner diameter of the mounting hole 21. The outer end of the threaded cap 2 has a threaded structure 22. The threaded cap 2 is inserted into the spoke hole of the rim or hub and cooperates with the nut 4 to connect the spoke rope 1 to the rim or hub.

[0027] The mounting head 3 is provided with a socket 31, and its outer wall is radially provided with a pressing opening 32 that communicates with the socket 31. The end of the spoke rope 1 is inserted into the socket 31. The pressing opening 32 is formed into a closed pressing structure by adhesive and machine pressing to fix the spoke rope 1, ensuring that the mounting head 3 is firmly sleeved on the end of the spoke rope.

[0028] Before installing the mounting head 3, first slip the toothed cap 2 into the spoke rope 1. After the mounting head 3 is fixed at the end of the spoke rope, move the toothed cap 2 so that its mounting hole 21 is tightly engaged with the mounting head 3. Since the outer diameter of the mounting head 3 matches the maximum inner diameter of the mounting hole 21, the mounting hole 21 gradually becomes smaller during the movement. It is slightly deformed by the pressure of the mounting head 3, which increases the outward pressure on the matching nut 4. The pressure is greater towards the end of the spoke rope 1, which effectively prevents the nut 4 from loosening and falling off the toothed cap 3 due to the vibration of the spoke rope 1 during riding. At the same time, the slight deformation of the mounting head 3 will also press it towards the socket 31, further pressing the mounting head 3 tightly to the end of the spoke rope 1.

[0029] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
