Abstract
Description
Technical Field
[0001] This utility model relates to an adjustable shock-absorbing vertical tube structure for bicycles that can provide shock absorption and cushioning for the handlebars. Background Technology
[0002] The existing bicycle handlebar structure, as disclosed in Taiwan Patent Certificate No. M495992, includes: a stem fixing seat (10), two support arms (20), and two locking bolts (30). The stem fixing seat (10) has a sleeve (11), a notch (12) is provided at the front of the sleeve (11), and a lug (13) extends forward on each side of the notch (12). A fixing part (14) is provided on the outer side of the lug (13), and a plurality of locking teeth (15) are arranged in a circular shape on the two fixing parts (14). The two opposite positions are locked. Each of the fixed teeth has a curved long hole (16) through it. A crossbar fixing seat (21) is provided in front of the support arm (20), and a set of joints (22) is formed on the inner side behind it. Each of the joints (22) has a plurality of engagement teeth (23) arranged in a circular shape. A locking hole (24) and a through hole (25) are passed through the engagement teeth on two opposite positions. The locking holes (24) and through holes (25) on the two supports (20) are inverted to form a shape in which the locking holes (24) on one support (20) and the through holes (25) on the other support (20) are aligned.
[0003] In use, the sleeve (11) is fitted around the outer periphery of the fork stem (40), allowing the stem mounting bracket (10) to be set on the bicycle's fork stem (40). The support arm (20) then rests against the fixing part (14) of the stem mounting bracket (10) with the assembly part (22). When the two locking bolts (30) pass through the through holes (25) of the two support arms (20) and the elongated holes (16) of the stem mounting bracket (10) respectively, and lock the locking holes (24) of the opposite support arms (20), the interlocking teeth (23) can be used to lock the connection. The mutual locking of the locking teeth (15) allows the support arm (20) to stop rotating. Through the fastening action of the locking bolt (30), the notch (12) can be forced to close, allowing the riser fixing seat (10) to be tightened on the front fork riser (40) using the sleeve (11). Finally, the handle bar (50) is installed on the crossbar fixing seat (21) of the second support arm (20). In this way, the angle of the handle bar (50) can be adjusted by loosening or re-locking the locking bolt (30).
[0004] However, the existing structure described above still has the following problems in practical applications: the support arm (20) can only provide the handlebar crossbar (50) for angle adjustment, but cannot make the handlebar crossbar (50) achieve the effect of buffering and shock absorption when in use, making the bicycle with the handlebar crossbar (50) relatively uncomfortable to ride.
[0005] Therefore, how to develop and improve the existing bicycle handlebar structure to address its shortcomings is a goal that the relevant industry needs to strive for. In view of this, the creator came up with the idea of this invention and designed it based on years of experience. After extensive discussions, sample testing, and multiple revisions and improvements, this utility model was launched. Utility Model Content
[0006] Technical issues to be addressed:
[0007] The existing handlebars cannot provide cushioning and shock absorption during use, resulting in less comfortable riding. This is the technical problem that needs to be solved.
[0008] Technical characteristics of the problem-solving process:
[0009] This utility model provides an adjustable shock absorber vertical tube structure for bicycles, comprising: a first body, at least one elastic shock absorber, and a second body. The first body has a first connecting portion at one end and a beveled first abutment at the other end. A pivot lug extends from the center of the first abutment. The pivot lug has a pivot hole and a receiving hole penetrating its side, allowing the elastic shock absorber to be inserted into the receiving hole. The elastic shock absorber has an inner and outer interlocking intermediate member and an outer ring. A through hole penetrates the center of the intermediate member. A first elastic body and a second elastic body are respectively filled in the two side regions between the intermediate member and the outer ring. The filling of the first and second elastic bodies allows the intermediate member and the outer ring to connect with each other. The first and second elastic bodies have different degrees of softness and hardness. The difference allows the overall hardness of the first elastomer to be greater than that of the second elastomer. One end of the second body has a second joint, and the other end has a beveled second abutment. A notch is formed in the center of the second abutment, and a first through hole and a second through hole are provided on the side through the notch. The notch provides a pivot lug for insertion, and a first shaft is inserted into both the first through hole and the pivot hole. With the mutual restraint of the first abutment and the second abutment, the second body can achieve a pivot assembly that can rotate in one direction on the first body. The second shaft is inserted into both the second through hole and the through hole, and the second body can also be connected to the elastic shock absorber installed in the receiving hole of the first body. Thus, an adjustable shock absorber vertical tube structure for bicycles is obtained.
[0010] Compared to the effectiveness of previous technologies:
[0011] This utility model provides an adjustable shock-absorbing vertical tube structure for bicycles. When the handlebars are subjected to downward force due to gripping, the second axle, through the intermediate component, presses the first elastic body to achieve a cushioning and shock absorption effect, making the bicycle relatively comfortable to ride. By removing the second axle, the second body can be easily rotated to remove and rotate the elastic shock absorber. Then, the elastic shock absorber and the second axle can be reinstalled, allowing the elastic shock absorber to be supported by the second elastic body. Utilizing the design that allows the elastic shock absorber to be installed on different sides, users can choose according to their different needs, thus achieving the substantial effect of adjustable shock absorption and cushioning force.
