Description

[Technical field] The invention relates to the technical field of bicycles, in particular a combination structure of bicycle handlebars and bar ends. [State of the art] When a bicycle is used for racing, a pair of bar ends is typically mounted on the handlebars. Each bar end has an extension base to which an armrest is attached. The bar ends allow the rider to adjust their riding position, with the armrest, for example, providing temporary support for the forearm, resulting in a more comfortable riding position. According to claim 11 of Taiwanese utility model no. M554441 entitled “Angle-adjustable handlebar end assembly for bicycles” with reference to Fig. 21, Fig. 22, Fig. 23, Fig. 24 to Fig. 25, the angle-adjustable handlebar end assembly comprises a handlebar end assembly to which an extension base is detachably attached at one end, wherein an overlapping edge is arranged on the extension base such that the overlapping edge extends from one side of the extension base, and wherein a through-opening is arranged on the overlapping edge;and a mounting seat corresponding to the bar end and attached to one of the two sides of an end of a bicycle stem, wherein a central hole is arranged on the mounting seat such that the central hole passes horizontally through the mounting seat, wherein an elongated mounting receptacle is arranged and designed on the top of the mounting seat such that the mounting receptacle is connected to the central hole, wherein a screw bolt is provided in the central hole, wherein the extension base with the overlapping edge rests against the top of the mounting seat so that a screw can be directed towards the through-hole and the mounting receptacle and inserted into the mounting seat and then secure the screw bolt in order to cause the overlapping edge to frictionally engage with or disengage from the mounting seat;Thus, with the screw loosened, the bar end can be rotated and, together with the extension base and the screw bolt, pivoted along the area of ​​the mounting bracket to adjust the pivot angle of the bar end in the vertical direction. While the conventional arrangement mentioned above allows for adjustment of the bar end's swivel angle, it has the following shortcomings. An armrest for supporting the rider's forearm while riding must be attached to the extension base, where one end of the bar end is mounted. The rider's forearm resting on the armrest exerts a vertical force on the extension base while riding. Furthermore, the bar end's angle adjustment mechanism is designed such that an overlapping edge is positioned on the extension base, extending from one side of the base. This overlapping edge has a through-hole, and a mounting seat corresponding to and interacting with the bar end is also provided.wherein the mounting seat is attached to one of the two sides of an end of a bicycle stem, wherein a central hole is arranged on the mounting seat such that the central hole passes horizontally through the mounting seat, wherein an elongated mounting receptacle is arranged and configured on the top of the mounting seat such that the mounting receptacle is connected to the central hole, wherein a screw bolt is installed in the central hole, wherein the extension base rests with the overlapping edge on the top of the mounting seat so that a screw can be directed towards the through-hole and the mounting receptacle and inserted into the mounting seat and then secure the screw bolt to cause the overlapping edge toto either fit snugly against the mounting seat or detach from it; thus, with the screw loosened, the bar end can be rotated and pivoted along the mounting area together with the extension base and the screw bolt to adjust the vertical pivot angle of the bar end. Therefore, when the rider rests their forearm on the armrest while riding, the forearm exerts a vertical force on the side of the extension base resting against the armrest, creating a vertical force similar to that of a cantilever, with the entire vertical force being borne by the extension base and the bar end, resulting inThe extension base and bar ends rest solely on the top of the extension base via their overlapping edges. A single screw is directed towards the through-hole in the overlapping edge and the mounting bracket, inserted into the mounting seat, and then tightens the bolt to either forcefully engage or disengage the overlapping edge from the mounting seat. With the screw loosened, the bar ends can be rotated and pivoted along the mounting area, along with the extension base and bolt, to adjust the bar end's vertical swivel angle. The fact that the screw must bear the entire force exerted by the forearm, acting like a boom, on the armrest located on the opposite side of the extension base during riding, leads to...that there is a risk of the overlapping edge bending radially in the direction of the bar end, or even of play occurring between the through-hole located on the overlapping edge and the screw, thus making effective angle adjustment of the entire bar end difficult. Therefore, the conventional arrangement of the type mentioned above requires improvement. [Purpose of the invention] Against this background, the applicant, drawing on his experience in the manufacture of bicycle parts, proactively sought solutions to problems, resulting in the inventive combination structure of bicycle handlebars and bar ends.
