Description

Technical Field

[0001] This utility model relates to bicycles, and more particularly to a bicycle vertical tube assembly structure. Background Technology

[0002] Early known bicycle stem tube covers were secured to the stem tube using fasteners such as screws. This design not only required riders to carry tools for installation and removal, but also resulted in problems such as a large number of components, complicated assembly, and high manufacturing costs.

[0003] The bicycle stem tube assembly disclosed in patent number M645488 has a cover that is engaged with the recessed parts on both sides of the stem tube via latching protrusions. The cover is also engaged with the lower part of the top cover via an upper latch. However, significant vibrations or swaying of the stem tube during riding can easily cause the cover to fall off, and impacts to the stem tube can also easily disengage the cover. Furthermore, since the cover cannot properly cover the top cover, the top cover is also susceptible to impacts that can cause the cover to disengage.

[0004] The bicycle stem with publication number M661879 uses a locking device to fix the upper shell to the stem. The cover is a vertically installed through hole in the upper shell. The cover is easy to detach from the upper shell due to road bumps, and the upper shell is also easy to detach from the cover due to external impact. Furthermore, the cover cannot cover the locking device. Utility Model Content

[0005] In view of the many defects of the existing bicycle stem assembly structure, the purpose of this utility model is to provide a bicycle stem assembly structure that makes it easier to attach the cover and makes the cover more secure.

[0069] Please see Figures 1 to 8 A preferred embodiment of the bicycle vertical tube assembly structure 1 of this utility model mainly includes a front fork tube 10, a vertical tube 20, an upper cover 30, a decorative cover 40, and a bottom cover 50.

[0070] The fork tube 10 has a tube body 11 and two lower retaining portions 12. The lower retaining portions 12 are part or all of the outer periphery of the tube body 11.

[0071] The vertical tube 20 has a tube hole 21, a longitudinal groove 22, multiple bolt holes 23, an upper stop portion 24, a transverse groove 25, and a cover edge 26. The tube hole 21 is fitted onto the tube body 11 of the fork tube 10. The longitudinal groove 22 is longitudinally connected to the tube hole 21. Each bolt hole 23 is locked by a first bolt B1 to secure the vertical tube 20 to the fork tube 10. The upper stop portion 24 is located above the tube hole 21. The transverse groove 25 is transversely connected to the tube hole 21. The cover edge 26 is formed on one side of the upper stop portion 24.

[0072] The upper cover 30 has a fitting hole 31, a lower abutment 32, a connecting hole 33, an annular groove 34, and two upper locking parts 35. The fitting hole 31 is fitted with the pipe hole 21 of the vertical tube 20, the lower abutment 32 abuts against the upper abutment 24 of the vertical tube 20, the connecting hole 33 is located in the middle of the lower abutment 32 and is locked to the vertical tube 20 by the second bolt B2, the annular groove 34 is arranged around the lower abutment 32, and the upper locking parts 35 are located in the annular groove 34, and the upper locking parts 35 are exactly part or all of the annular groove 34.

[0073] The cover 40 has a cover body 41, two latching parts 42, two latching tube parts 43, a longitudinal piece 44, a cover front edge 45, and two first anti-detachment parts 46. The cover body 41 covers the upper cover 30 and the vertical tube 20. The latching parts 42 are inserted into the annular groove 34 of the upper cover 30 and latched into the upper latching part 35. The latching tube parts 43 pass through the transverse groove 25 of the vertical tube 20 and slide against the tube body 11 of the fork tube 10 and latch into the lower latching part 12. The longitudinal piece 44 is inserted into the longitudinal groove 22 of the vertical tube 20. The cover front edge 45 and the cover edge 26 of the vertical tube 20 are engaged. The first anti-detachment parts 46 are located below the cover 40.

[0074] The bottom cover 50 is fitted onto the fork tube 10 and covers the bottom of the stem tube 20 and the trim cover 40. The bottom cover 50 has two second anti-detachment parts 53 that mate with the first anti-detachment part 46 of the trim cover 40. The trim cover 40 can only be disengaged by the bottom cover 50 moving downwards. The first anti-detachment part 46 and the second anti-detachment part 53 can be bevels, protrusions, grooves, or other mating structures.

[0075] In this embodiment, the two latching portions 42 of the trim cover 40 are latched onto the upper latching portion 35 of the upper cover 30, and the two latching tube portions 43 of the trim cover 40 are latched onto the lower latching portion 12 of the fork tube 10. This allows for quick and secure latching, preventing the trim cover from easily falling off due to impact, thus achieving the purpose of this utility model. Furthermore, the longitudinal piece 44 of the trim cover 40 is inserted into the longitudinal groove 22 of the vertical tube 20, preventing lateral movement and further contributing to preventing detachment. Additionally, the bottom cover 50 has two second anti-detachment portions 53 that cooperate with the first anti-detachment portion 46 of the trim cover 40. The trim cover 40 can only be released from its latching position by the bottom cover 50 moving downwards, further aiding in preventing detachment.

[0076] Another embodiment of the bicycle vertical tube assembly structure 1 of this utility model, such as Figure 9 As shown, it is largely the same as the aforementioned embodiment, with the main difference being that the bottom cover 50 may not be included, while still achieving the purpose of this utility model.

[0077] Another and yet another embodiment of the bicycle vertical tube assembly structure 1 of this utility model, such as Figure 10 and 11 As shown, it is largely the same as the previous embodiment, except that: the cover 40 also has a feeding part 49 attached to the cover body 41, such as a feeding seat or a mounting hole, which can be used to mount objects such as a stopwatch or a display.

[0078] In addition to the above embodiments, the present invention can also be implemented in the following variations:

[0079] For example, in addition to being part or all of the annular groove 34 as described above, the upper locking portion 35 of the upper cover 30 may be changed to a groove (not shown) or a protrusion (not shown) for engaging with the locking portion 42 of the cover 40.

[0080] Alternatively, the lower locking portion 12 of the fork tube 10, in addition to being part or all of the tube body 11 as described above, can be modified into a groove (not shown) or a protrusion (not shown) for engaging with the cover portion 42 of the trim cover 40. That is, the two tube locking portions 43 of the trim cover 40 engage with the two lower locking portions 12 of the fork tube 10, or the two tube locking portions 43 of the trim cover 40 engage with the tube body 11 of the fork tube 10.

[0081] Alternatively, in addition to having both a cover portion 42 and a tube portion 43 as described above, the cover 40 may be modified to have only a cover portion 42 without a tube portion 43, or the cover 40 may be modified to have only a tube portion 43 without a cover portion 42.

[0082] In summary, the bicycle vertical tube assembly structure 1 provided by this utility model can facilitate the structure of the decorative cover 40, and can be inserted into the upper cover 30 and / or the fork tube 10 without any tools, thereby solving the shortcomings of the prior art where the decorative cover disassembly and assembly procedures are cumbersome and tools must be used for installation.

[0083] Finally, it must be stated again that the constituent components disclosed in the above embodiments of this utility model are merely illustrative examples and are not intended to limit the scope of this utility model. Substitutions or variations of other equivalent components should also be within the protection scope of this utility model.
