M276779 四、創作說明（1) 【新型所屬之技術領域】 本創作係涉及自行車把手之伸縮調整構造改良，旨在 提供一可讓使用者依需要調整把手高度的伸縮調整構造。 【先前技術】 按，一般自行車之前輪主要係用以控制自行車之平衡 以及轉向，故基本上自行車的前輪與把手之間主要係透過 前叉的連接，以期在自行車把手轉向的時後，能夠讓前輪 隨著把手擺動，達到順利轉向以及控制平衡之目的；因此 ，自行車主要係在前叉中間以及把手的中間位置構成聯結 ¥，讓前輪左、右轉向的反應一致，避免造成操控的困難。 如第一圖所示，即為一般自行車習用的前叉與把手聯 結構造外觀立體圖；其中，自行車係在其前叉1 0的中間 位置直設有一中空的芯桿11 ，以及在把手立管20的中 間位置直設有一可相對應套入芯桿1 1的軸桿2 1 ，並且 透過相關鎖緊元件將芯桿1 1與軸桿2 1鎖緊，而達到構 成把手立管2 0與前叉1 0之間的聯結作用。 其鎖緊元件之結構一般如第一圖所示，其前叉1 0中 間並於軸桿2 1下方係設有一螺接件1 3 ，且在螺接件1 3的軸心設有一穿孔1 3 1 ，另有一螺栓3 1穿過穿孔1 _ 3 1並且與螺接件1 3螺接，且其螺接件1 3與軸桿2 1 _的貼抵面係為相對應接合的斜切面形態，如此即可透過螺 栓3 1將芯桿1 1與軸桿2 1鎖緊，並構成把手立管2〇 與前叉1 0之間的聯結作用。M276779 4. Creation Description (1) [Technical Field to which the New Type belongs] This creation relates to the improvement of the telescopic adjustment structure of a bicycle handlebar, and aims to provide a telescopic adjustment structure that allows a user to adjust the height of the handlebar as needed. [Previous technology] According to the general, the front wheel of a bicycle is mainly used to control the balance and steering of the bicycle, so basically the front wheel of the bicycle and the handlebar are mainly connected through the front fork. The front wheel swings with the handle to achieve smooth steering and control of balance; therefore, the bicycle is mainly connected in the middle of the front fork and the middle position of the handle to form a joint ¥, which allows the front and left steering reactions to be consistent, avoiding difficulties in handling. As shown in the first figure, it is a perspective view of the conventional front fork and handlebar coupling structure of a common bicycle. Among them, the bicycle is provided with a hollow core rod 11 in the middle position of the front fork 10, and a handle riser 20 In the middle position, a shaft rod 2 1 which can be correspondingly sleeved into the core rod 1 1 is provided, and the core rod 11 and the shaft rod 21 are locked through the relevant locking elements, so as to form the handle riser 20 and the front. The coupling effect between the forks 10. The structure of the locking element is generally as shown in the first figure. A screw joint 1 3 is arranged in the middle of the front fork 10 and below the shaft 2 1, and a perforation 1 is provided on the axis of the screw joint 13. 3 1, and another bolt 3 1 passes through the perforation 1 _ 3 1 and is screwed with the screw connection 13, and the abutting surface of the screw connection 13 and the shaft 2 1 _ is a correspondingly beveled cutting surface In this way, the core rod 11 and the shaft rod 21 can be locked through the bolt 31, and the connection effect between the handle riser 20 and the front fork 10 can be formed.

Creation instructions (2) However, the conventional joint structure cannot adjust the height of the handle riser, that is, the bicycle of the same specification will feel the position of the handle because it is different in rider's body-too high or too short, and thus This results in restrictions on the applicable objects; and its locking elements have many parts and complicated assembly structures, and other tools are required to lock or relax the bolts. [New content] The creation of "Telescopic adjustment structure of bicycle handlebars" is provided with a cut groove on the front fork. The cut groove extends a predetermined length along the axial direction of the front fork and is on both sides of the cut groove. A thread of a fixed section is provided at the position, so as to screw a bead bowl group into the thread and press it tightly on the top of the front fork, and a telescopic tube for the handle riser is sleeved in the front fork. A lock member is fixed on the upper end of the bead bowl group, so that the telescopic tube can be moved up and down in the front fork, and the lock member can be used to fasten the front fork and clamp the telescopic tube. '' In particular, the clamping effect of the frame head can be released by loosening the locking element, and after the depth of the connection between the frame head and the telescopic tube is appropriately changed, the locking effect of the locking element is used to By fixing the insertion depth between the sleeve and the connecting rod, the purpose of adjusting the height of the handle can be easily achieved. [Implementation] ^ In order to make your reviewing committee aware of the composition and operation of this creation, we will explain it in conjunction with the drawings as follows: The "Telescopic adjustment structure of bicycle handlebars" in this creation has the telescopic adjustment structure as described in Figures 2 to 4; among them, attached to the front fork 1 of the bicycle

Creative Instructions (3) There is a cut groove 14 on the groove. The cut groove 14 extends along the axial direction of the front fork 10 with a predetermined length, and the cut groove 1 4 A thread 15 of a fixed section is provided on both sides to screw a bead bowl group 40 into the thread 15 and press it tightly on the top of the front fork 10, and a middle position of the handle riser 20 is provided with a straight phase. The telescopic tube 50 corresponding to the front fork 10 is fixed to the fixed end 16 of the front fork 10 using a locking member 60. When the whole assembly is performed, the bead bowl group 40 is first screwed into the front fork 10 with the thread 15, and after pressing firmly on the top of the front fork 10, the top of the front fork 10 and a fixed end 16 are exposed, as described above. The thread 15 extends to the fixed end 16 f. The telescopic tube 50 is sleeved into the front fork 10, and the front fork 10 and the telescopic tube 50 overlap each other with a fixing hole 17 and a long slot hole 5 1 The fixing hole 17 can be used for a fixing member 3 2 to pass between the front fork 10 and the telescopic tube 50, and a locking member 60 is set on the fixing end 16 of the front fork 10, as in this In the embodiment shown in the figure, the locking member 60 can be in the form of quick release, and the fixing member 32 can be inserted between the locking member 60, the front fork 10, and the telescopic tube 50, so that the telescopic tube 50 can be placed in front. The fork 10 moves up and down, and the range of its up and down movement is determined by the fixing member 3 2 being clamped in the upper and lower end of the long slot 5 1, and the locking member 60 can be used to tighten the front fork 10 and further expand and contract. The tube is clamped and fixed. It is worth mentioning that the locking effect of the front fork 10 can be released by loosening the locking member 60, and the lock depth can be changed after properly changing the insertion depth between the front fork 10 and the telescopic tube 50. The latch 60 is used to fix the insertion depth between the front fork 10 and the telescopic tube 5 ′ 0, so that the purpose of adjusting the height of the handle can be easily achieved, and the user can adjust the height of the handle in real time as needed.
