Description

TECHNICAL FIELD

[0001] The utility model relates to a bicycle vertical pipe assembly, especially to a structure capable of rotating a handlebar, so that the handlebar does not occupy too much space when not in use, and the bicycle is conveniently stored. BACKGROUND

[0002] Bicycles are increasingly used as a means of transportation, and they are environmentally friendly and provide exercise. Therefore, bicycles are increasingly used. In urban areas, public bicycles are provided for people to rent for short commutes, and many people ride bicycles as a form of leisure on weekends.

[0003] A bicycle is assembled from multiple components. A vertical pipe, commonly known as a stem, is a component that connects a handlebar to a front fork. The vertical pipe can provide different angle specifications, allowing the handlebar to be fixed at a higher or lower position than the horizontal position of the vertical pipe to accommodate different riding postures. In general use, the handlebar and the frame are perpendicular to each other. The width of the handlebar represents the width of the entire bicycle. Therefore, when storing the bicycle, the handlebar occupies a certain amount of space, making it difficult to store.

[0004] To meet the storage needs, the handlebar and the front fork need to be designed to rotate relative to each other. Patent No. TWM404815 provides a bicycle stem quick-release steering device. The device has a stem, a support, a pivot, a pull tab, and a positioning mechanism. The ends of the pull tab are connected to the ends of the pivot. The user presses the positioning buckle to release the fixed state of the pull tab, then pulls the pull tab to pivot the pivot in the pivot hole, and the support can rotate relative to the stem. In addition, Patent No. TWM570265 also provides a bicycle stem quick-release steering device. The structure for fixing the lever is a locking mechanism. The locking mechanism is arranged on the surface of the support and abuts against the lever, so that the lever cannot rotate the tenon relative to the support. The user needs to retract the locking mechanism first to control the rotation of the lever, so that the support can rotate relative to the stem.

[0005] However, as known from the above-mentioned prior art, in order to prevent the vertical pipe (support) from rotating freely, a safety mechanism for fixing the pull tab and the lever is provided. Currently, the safety mechanism is designed on the vertical pipe, which directly changes the structure of the vertical pipe, resulting in a decrease in the structural strength of the vertical pipe. Since the safety mechanism occupies the space of the vertical pipe itself, the bicycle can only use a vertical pipe that is large in size and heavy in weight. Therefore, how to provide a vertical pipe that can rotate the handlebar without damaging the structure of the vertical pipe is a direction considered by the applicant. SUMMARY

[0006] In view of the above-mentioned existing bicycle vertical pipe still has many defects, the main purpose of the present application is to provide a bicycle vertical pipe assembly, the handlebar seat can rotate relative to the base, so as to achieve the function of the handlebar can be driven to fold.

[0007] In order to achieve the above-mentioned main purpose, the present application provides a bicycle vertical pipe assembly, which comprises a handlebar seat, a base and a locking assembly. The handlebar seat has a first sleeve hole formed at one end of the handlebar seat, a pressing part formed at the other end of the handlebar seat and a pivot part formed between the first sleeve hole and the pressing part. The base is arranged at the pivot part of the handlebar seat, and the base has a second sleeve hole. The handlebar seat can rotate relative to the base. The locking assembly is arranged at the pressing part of the handlebar seat, and the locking assembly has a main operating handle, a sub operating handle pivotally arranged at the main operating handle and a locking member connected to the main operating handle. The sub operating handle can abut against the locking member to limit the locking member. When the sub operating handle and the locking member are out of abutting relationship, the main operating handle can rotate relative to the locking member to control the pressing force of the pressing part.

[0008] Through the above technical features, the handlebar of the bicycle is arranged in the first sleeve hole of the handlebar seat, and the front fork vertical pipe is arranged in the second sleeve hole of the base, so that the bicycle vertical pipe assembly is assembled on the bicycle. Since the handlebar seat is connected to the base through the pivot part, when the handlebar seat rotates relative to the base, the handlebar can rotate together, so that the handlebar changes from the perpendicular type to the parallel type relative to the frame, thereby reducing the width of the whole bicycle and facilitating the storage in a narrower space. In addition, the sub operating handle of the locking assembly is arranged as a safety mechanism at the main operating handle. By abutting the sub operating handle to the locking member, the locking member is prevented from being actuated, so that the handlebar seat cannot rotate relative to the base, thereby avoiding accidents during riding.

[0009] Preferably, the handlebar seat further comprises a handle frame and an end cover. The end cover is detachably locked to the handle frame, and the handle frame and the end cover jointly form the first sleeve hole. In this way, by combining the end cover and the handle frame, the handlebar is conveniently installed on the handlebar seat, and the function of replacing the handlebar is provided.

[0010] Preferably, the pivot part of the handlebar seat forms a pivot hole, so that the base is arranged in the pivot hole and clamped by the pivot part. In this way, the handlebar seat is sleeved with the base through the pivot hole, so that the base is fixed to the handlebar seat, and the handlebar seat can also rotate relative to the base to fold the handlebar.

[0011] Preferably, the base is a hollow tubular structure, the second sleeve hole is formed in the base, the outer surface of the bottom end of the base further forms a tightening part, and the base is arranged in the pivot hole of the pivot part, and the tightening part abuts against the bottom end of the pivot part. In this way, the base is sleeved with the front fork vertical pipe through the second sleeve hole, and the base is stably fixed to the front fork vertical pipe through the tightening part, so that the base serves as a connecting element between the handlebar seat and the front fork vertical pipe.

[0012] Preferably, the handle seat further has a positioning assembly disposed at the pivot portion, and the base further has a positioning portion formed at the top end of the base, and the positioning portion of the base is connected to the positioning assembly. Thus, when the handle seat is rotated relative to the base, the positioning assembly and the positioning portion can provide an accurate position for the handle seat to be fixed.

[0013] Preferably, the positioning assembly of the handle seat has a positioning plate, at least one first fixing member, a positioning steel ball, a positioning spring, and a second fixing member, and the pivot portion of the handle seat has a through hole for accommodating the positioning steel ball, the positioning spring, and the second fixing member, and the positioning plate has a plurality of positioning holes, and the positioning steel ball is engaged in different positioning holes according to the position of the handle seat relative to the base. Thus, when the handle seat is rotated, the positioning steel ball moves along the surface of the positioning plate, and when the positioning steel ball moves to the position of the positioning hole, the tension of the positioning spring pushes the positioning steel ball into the positioning hole, so as to accurately define the position of the handle seat to be fixed.

[0014] Preferably, the positioning plate of the positioning assembly is fixed to the positioning portion of the base by the first fixing member. Thus, the positioning plate is fixed to the base, so that when the handle seat is rotated, only the elements disposed in the through hole are moved, and the positioning steel ball moves along the surface of the positioning plate along the circular path of rotation.

[0015] Preferably, the locking member of the locking assembly has a shaft, a pressing member, a pivot, and a pressing plate, one end of the shaft is connected to the pressing member, the other end of the shaft passes through the pressing plate, and the shaft is fixed to the main operating handle by the pivot, and the pressing plate abuts against the main operating handle. Thus, the main operating handle and the shaft are in a linked state, and when the main operating handle is rotated, the pressing force of the pressing portion can be changed by the displacement of the shaft and the pressing member, so as to achieve the locking or unlocking effect.

[0016] Preferably, the shaft of the locking member further has a limiting portion for abutting against a stop end of the auxiliary operating handle, and the locking assembly further has a return spring disposed at the main operating handle and abutting against an actuating end of the auxiliary operating handle. Thus, the return spring makes the auxiliary operating handle abut against the limiting portion of the shaft automatically, so as to prevent the shaft from being actuated, and the user needs to press the auxiliary operating handle and resist the tension of the return spring, so as to make the shaft in a freely actuated state, and the main operating handle can drive the shaft to be actuated.

[0017] Preferably, the pressing portion of the handle seat is two lugs, and a gap is formed between the two lugs, the shaft of the locking member passes through the two lugs to be connected to the pressing member, and the distance of the gap is controlled when the main operating handle is rotated relative to the locking member. Thus, the pressing force of the pressing portion is changed according to the distance of the gap, and the force of the pivot portion for fixing the base is changed, so that the handle seat is in a state of fixing the base or not fixing the base.

[0018] Preferably, the top surface of the handlebar seat further forms a mounting portion which is a flat surface and covers the pivot portion. By this way, the top surface of the handlebar seat is designed to be flat, and can be used as the mounting portion to mount other accessories of the bicycle, and the pivot portion does not affect the position where the accessories can be mounted.

[0019] The detailed structure, characteristics, assembling or using mode of the bicycle vertical pipe assembly of the present application will be described in the following detailed description of the embodiments.

[0072] Please refer to Figure 1 and Figure 2 The bicycle vertical pipe assembly 10 of the present application mainly comprises a handlebar seat 20, a base 30 and a locking assembly 40.

[0073] The handlebar holder 20 has a first sleeve hole 21, a pressing portion 22, a pivot portion 23, a handlebar 24, an end cover 25 and a mounting portion 26. The handlebar 24 is formed at one end of the handlebar holder 20, and the end cover 25 is locked to the handlebar 24. The handlebar 24 and the end cover 25 jointly form the first sleeve hole 21. The handlebar 50 of the bicycle is assembled to the handlebar holder 20 through the first sleeve hole 21. The pressing portion 22 forms two lugs 221 at the other end of the handlebar holder 20. The two lugs 221 have a gap 222 therebetween. The pivot portion 23 is formed between the first sleeve hole 21 and the pressing portion 22. The pivot portion 23 extends downward from the handlebar holder 20 to form a tube having a pivot hole 231. In addition, the mounting portion 26 is formed on the top surface of the handlebar holder 20. The mounting portion 26 is a flat surface covering the pivot portion 23, or a cover sheet 261 can be used to cover the pivot hole 231 of the pivot portion 23, so that the mounting portion 26 is flat. The user can arrange the accessories 262 of the bicycle on the mounting portion 26.

[0074] The handlebar holder 20 further has a positioning assembly 27. The positioning assembly 27 has a positioning sheet 271, at least one first fixing member 272, a positioning steel ball 273, a positioning spring 274 and a second fixing member 275. A through hole 232 is formed in the pivot portion 23. The positioning steel ball 273, the positioning spring 274 and the second fixing member 275 are accommodated in the through hole 232. The positioning sheet 271 has a plurality of positioning holes 2711. The second fixing member 275 is fixed in the through hole 232. One end of the second fixing member 275 abuts against one end of the positioning spring 274. The other end of the positioning spring 274 abuts against the positioning steel ball 273. The second fixing member 275 is used to limit the positions of the positioning spring 274 and the positioning steel ball 273 in the through hole 232. The positioning steel ball 273 is pushed towards the outside of the through hole 232 by the tension of the positioning spring 274, so that the positioning steel ball 273 is clamped in different positioning holes 2711 of the positioning sheet 271.

[0075] The base 30 is a hollow tubular structure. The base 30 has a second sleeve hole 31, a tightening portion 32 and a positioning portion 33. The tightening portion 32 is formed on the outer surface of the bottom end of the base 30. The positioning portion 33 is formed on the top end surface of the base 30. The base 30 is sleeved on the front fork tube 60 through the second sleeve hole 31. A screw 34 is locked in the tightening portion 32, so that the base 30 clamps and fixes the front fork tube 60. The base 30 is also sleeved in the pivot hole 231 of the pivot portion 23 of the handlebar holder 20. The positioning sheet 271 of the positioning assembly 27 is assembled to the positioning portion 33 through the two first fixing members 272. The tightening portion 32 abuts against the bottom end of the pivot portion 23. In this way, the handlebar holder 20 can rotate relative to the base 30.

[0076] The locking assembly 40 has a main operating handle 41, a sub operating handle 42, a locking member 43 and a return spring 44. The main operating handle 41 has a receiving slot 411 formed on one side thereof, and the sub operating handle 42 is arranged in the receiving slot 411 and pivotally connected to the main operating handle 41 by a pivot member 45. The pivot member 45 is arranged between a stop end 421 and an operating end 422 of the sub operating handle 42. The locking member 43 has a shaft 431, a pressing member 432, a pivot 433 and a pressing plate 434. The shaft 431 passes through two lugs 221 of the pressing portion 22 of the handlebar base 20, and one end of the shaft 431 is connected to the pressing member 432, and the other end of the shaft 431 passes through the pressing plate 434 and extends into the receiving slot 411 of the main operating handle 41. The pivot 433 passes through the main operating handle 41 and the shaft 431 and is clamped to the main operating handle 41. One side of the pressing plate 434 abuts against the outer surface of one of the lugs 221, and the other side of the pressing plate 434 abuts against the cam-shaped portion of the main operating handle 41. Thus, the main operating handle 41 can tightly abut against the pressing plate 434 and pivot about the center of the pivot 433. Due to the design of the cam-shaped portion of the main operating handle 41, when the main operating handle 41 is pivoted, the shaft 431 and the pressing member 432 are displaced to change the pressing force of the pressing portion 22. The end of the shaft 431 connected to the pivot 433 further has a limiting portion 4311. The return spring 44 is arranged in the receiving slot 411 of the main operating handle 41, one end of the return spring 44 is fixed to the main operating handle 41, and the other end of the return spring 44 abuts against the operating end 422 of the sub operating handle 42. The return spring 44 pushes the operating end 422 of the sub operating handle 42 to pivot the sub operating handle 42 about the pivot member 45, and the stop end 421 abuts against the shaft 431.

[0077] The following describes the handlebar 50 from the use state to the storage state. Please refer to Figures 3 to 7 .

[0078] Firstly, in the use state, the stop end 421 of the sub operating handle 42 abuts against the limiting portion 4311 of the shaft 431 of the locking member 43, so that the main operating handle 41 cannot be pivoted, and the handlebar base 20 is kept fixed to the base 30, thereby preventing the handlebar 50 from being pivoted accidentally during riding and causing danger. Therefore, the user needs to apply force to the operating end 422 of the sub operating handle 42 to resist the tension of the return spring 44, and the stop end 421 of the sub operating handle 42 is separated from the limiting portion 4311 of the shaft 431, so that the abutting relationship between the sub operating handle 42 and the locking member 43 is released, and the shaft 431 can be freely operated, such as Figure 3 , Figure 4As shown. In succession, the main operating handle 41 is pulled outward, the main operating handle 41 rotates closely against the surface of the pressing plate 434, and with the rotation range, the shaft 431 and the pressing member 432 are driven to displace, and the gap 222 of the pressing portion 22 of the handlebar seat 20 is also increasingly large, as shown. Figure 5 As shown, so that the pressing force of the pressing portion 22 on the base 30 is reduced, that is, the assembly relationship of the handlebar seat 20 and the base 30 is released, the handlebar seat 20 can rotate relative to the base 30, and the handlebar 50 fixed to the handlebar seat 20 is converted from a vertical form to a parallel form to the frame, as shown. Figure 6 As shown.

[0079] When the handlebar seat 20 is rotated, the rotating force resists the positioning spring 274 of the positioning assembly 27, so that the positioning steel ball 273 of the positioning assembly 27 is driven out of one of the positioning holes 2711 of the positioning sheet 271, and the positioning steel ball 273 moves along the surface of the positioning sheet 271 provided on the base 30 to the position of the other positioning hole 2711, and the positioning steel ball 273 falls into the positioning hole 2711 to be clamped on the positioning sheet 271, which represents that when the handlebar seat 20 is rotated by 90°, the user will hear the sound of the positioning steel ball 273 falling into the positioning hole 2711, and it can be determined that the handlebar seat 20 has been rotated to the target position, as shown. Figure 7 At this time, the user can press the secondary operating handle 42 again and pull the main operating handle 41 inward, drive the shaft 431 and the pressing member 432, so that the gap 222 of the pressing portion 22 is also reduced, the pressing force of the pressing portion 22 on the base 30 is increased, and the handlebar seat 20 is fixed on the base 30 to avoid arbitrary rotation of the handlebar seat 20.

[0080] In summary, the bicycle vertical pipe assembly 10 provided by the utility model fixes the handlebar 50 by the handlebar seat 20, fixes the front fork vertical pipe 60 by the base 30, and rotates the handlebar 50 by the characteristic that the handlebar seat 20 can rotate relative to the base 30, so that the handlebar 50 can be rotated, and the effect of folding the handlebar 50 is achieved. In addition, the secondary operating handle 42 used as a safety mechanism is arranged in the main operating handle 41, and the secondary operating handle 42 blocks the action of the locking member 43 to prevent the main operating handle 41 from loosening and causing the handlebar seat to rotate, so that accidents can be avoided during riding. Compared with the prior art, the safety mechanism is not directly arranged on the handlebar seat itself, so that the structure of the handlebar seat itself is not damaged, the original structural strength is maintained, and a bicycle vertical pipe assembly of a specific size is not required.

[0081] Finally, it must be pointed out again that the constituent elements disclosed in the above-mentioned embodiments of the utility model are only for illustration and are not intended to limit the scope of the case, and the replacement or change of other equivalent elements should also be covered by the protection scope of the case.
