Description

Bicycle threading device

The present invention relates to a bicycle, and in particular to a bicycle threading device.

Known bicycle pipe fittings, such as but not limited to the head tube, front fork tube and handlebar stem, are mostly made of metal materials, and are processed by cutting to form threading holes for facilitating threading (such as brake cables or shift cables), which is convenient for wiring and has better aesthetics and safety.

However, the edges of the threading holes processed by cutting and pinning are too sharp and can easily cut the wires of the bicycle. If the aforementioned problem is to be improved, the edges of the holes need to be processed to form chamfers, which increases the processing cost and has a disadvantage that needs to be improved urgently.

Therefore, it is necessary to provide a novel and advanced bicycle threading device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a bicycle threading device which can prevent wire cuts and is easy to manufacture.

To achieve the above-mentioned purpose, the present invention provides a bicycle threading device, comprising: a pipe and at least one set. The pipe comprises at least one through hole and at least one hole wall surrounding the at least one through hole; the at least one set is at least partially disposed in the at least one through hole; wherein the pipe and the at least one set are made of different materials; and when viewed along an axial direction of the at least one through hole, a threading hole for a wire to be threaded is formed between each set and one of the hole walls.

The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained in advance.

Please refer to FIGS. 1 to 6 , which show a preferred embodiment of the present invention. The bicycle threading device 1 of the present invention includes a pipe 10 and at least one set 20.

The pipe 10 includes at least one through hole 11 and at least one hole wall 12 surrounding the at least one through hole 11; the at least one set 20 is at least partially disposed in the at least one through hole 11; wherein the pipe 10 and the at least one set 20 are made of different materials; and when viewed along an axial direction of the at least one through hole 11, a threading hole 30 for a wire 2 to pass through is formed between each set 20 and one of the hole walls 12. Thus, the at least one through hole 11 can be formed in the pipe 10 by cutting or other commonly used processing methods, and the at least one set 20 prevents the wire 2 from contacting an edge 121 of the at least one hole wall 12, thereby achieving the effect of protecting the wire 2 and facilitating processing.

Preferably, the hardness of the at least one set 20 is less than the hardness of the pipe 10, and the protective effect is good. For example, the pipe 10 can be made of iron, aluminum alloy, carbon fiber and other materials, and the at least one set 20 can be made of silicone, plastic, rubber and other materials, and can be formed into the required configuration according to the needs, which is convenient for manufacturing and installation. It should be particularly noted that compared with the previous technology, the processing of each through hole 11 can be simplified, and the at least one set 20 and the at least one hole wall 12 are matched to enclose the required threading holes 30, which is convenient for processing and easy to change the configuration. In other embodiments, the at least one set can also be made of metal material, which can be selected according to needs.

Each of the sleeves 20 is flush with or protrudes from at least one end of the through hole 11; in a radial direction of the at least one hole wall 12, each of the sleeves 20 extends along the edge 121 of the hole wall 12, effectively preventing the wire 2 from contacting the edge 121 of the at least one hole wall 12. Preferably, in the axial direction, the height of the at least one sleeve 20 at least partially corresponds to the height variation of the at least one hole wall 12, as shown in FIG. 4, to prevent the at least one sleeve 20 from protruding too much and hindering threading.

Specifically, each of the kits 20 includes a sleeve portion 21 and a clamping portion 22. The sleeve portion 21 at least partially extends corresponding to the at least one through hole 11 and is located in the at least one through hole 11. The clamping portion 22 extends transversely to the sleeve portion 21 and can abut against an outer surface of the pipe 10 around the at least one through hole 11 to facilitate assembly. Preferably, the pipe 10 further includes at least one clamping groove 13 adjacent to the at least one through hole 11. The clamping portion 22 of each of the kits 20 can be accommodated in one of the clamping grooves 13 to achieve a positioning effect and facilitate subsequent assembly. Each of the kits 20 can also be attached to the pipe 10 with an adhesive, which has good stability and is not easy to fall off.

Furthermore, the pipe 10 includes a first hole slot 14 and a second hole slot 15 transverse to the first hole slot 14, the at least one through hole 11 is disposed on a side of the first hole slot 14 adjacent to the second hole slot 15 and is connected to the second hole slot 15, and the at least one set 20 is disposed on a side of the at least one through hole 11 away from the first hole slot 14. Thus, when the wire 2 bends and extends from the second hole slot 15 toward the first hole slot 14, the wire 2 can abut against the at least one set 20 without contacting the edge 121 (cut edge) of the at least one hole wall 12, thereby effectively avoiding friction damage. In this embodiment, the pipe 10 is a handlebar stem, the first hole 14 is a fixing hole for connecting a steering tube, and the second hole 15 extends toward a side away from the fixing hole for connecting a handlebar. The brake cable or the shift cable of the bicycle can extend through the second hole 15 toward the ground hole to the steering tube, as shown in FIG. 3, which is convenient for wiring.

Furthermore, the pipe 10 includes two unconnected through holes 11, the sleeve portion 21 includes two ear pieces 211 respectively penetrated through the two through holes 11, and the clamping portion 22 is spaced to connect the two ear pieces 211, as shown in FIG5 and FIG6, so that the plurality of wires 2 can be distributed to the two unconnected threading holes 30 as required, reducing mutual interference. The at least one clamping slot 13 is adjacent to one end of the two through holes 11 relatively far from the second hole slot 15 and connected to the two through holes 11; each ear piece 211 at least partially corresponds to one of the hole walls 12 and extends in an arc, which is convenient for manufacturing and installation and has good bonding stability. In this embodiment, the two ear pieces 211 and the clamping portion 22 are a single component formed by integral injection molding, which has good structural strength and is easy to manufacture; the thickness of each ear piece 211 gradually decreases toward the two opposite sides of the ear piece 211 to smoothly connect with the hole wall 12, thereby preventing the wire 2 from being stuck at the joint between the two to ensure smooth operation.

With reference to FIG. 4 , when viewed along an axial direction of the second hole slot 15 , the two ears 211 protrude from the second hole slot 15 , so that when the handlebar stem rotates relative to the steering tube, the wire 2 and the edge 121 of each hole wall 12 are separated by the protruding two ears 211 , and the wire 2 can be effectively prevented from being cut. Preferably, the at least one set 20 does not protrude from an outer surface of the pipe 10 , which is aesthetically pleasing. In other embodiments, the two ears can also be flush with the at least one hole wall 12 and not protrude relatively; each through hole can also be provided with a set.
