The new technical field, prior technology, content, and implementation methods are briefly explained.) I. The new technical field belongs to the technical field of a folding bicycle, especially a folding bicycle. Handlebar improvements. Second, the previous technology / f, the characteristics of the folding bicycle is that its components can be folded or retracted to reduce the volume to facilitate storage and storage, and in order to reduce the volume of the folded bicycle as much as possible, so how to deal with the protruding handlebars of the folded bicycle is currently One of the issues that manufacturers are eager to solve. Knownly developed a variety of ways to store the handlebars of folding bicycles. The most common way is to fold down the stem of the handlebar; others also turn the handlebar 90 degrees around the fold line of the stem and then down Folding, fold down the two sides of the handlebar separately, and directly detach the handlebar and tube from the frame. Please refer to Fig. 1. The folded state of the handlebar of the folding bicycle which is applicable to the first method mentioned above is shown. As shown in the figure, the erector 13 of the folding bicycle 1 is provided with a folding joint 14 at the connection point with the frame. When the user wants to store the folding bicycle and call it to be folded, it can be actuated by the folding joint 14 Fold the standpipe 13 down next to the front wheel 11, and then close the rear wheel 12 towards the standpipe 13 so that it is parallel to the front wheel 11. 'The tube U and the flat tube 15 connected to the front end will = Between the front wheel 11 and the rear wheel 12, and the front wheel 丨 丨, the rear wheel 12, and the handlebar will be approximately parallel. M242448 However, 'because the handles at the two ends of the handlebar flat fl5 are closed (mid-out-a brake handle 17, and there is a gap between the handle 16 and the brake handle 17: there is a distance of about 10 cm, so after folding, the handle 16 The brake lever 17 is often in the same horizontal plane and is juxtaposed with the two wheels, so that: the wheel 11 and the rear wheel 12 are hindered by the distance between the material handle 16 and the brake handle 17 and so on. In addition, if the rear wheel 13 Designed to gather in the direction relative to the riser 13 'Although it can ensure that the two wheels are gathered side by side, the brakes will be sold to the other side of the wheels, which also makes the folded bicycle 1 larger, not very 3. The new content The main purpose of this creation is to provide an improved handlebar for a folding bicycle. The handlebar is folded at the top of the tube of the folding bicycle handlebar. Between the front and rear wheels, or on one side, the space occupied can be reduced by loosening the clamping device so that the handlebar and brake handle of the handlebar can be rotated to be slightly parallel to the front and rear wheels to help the two wheels. and More compact. Another purpose of this creation is to provide an improved handlebar for a folding bicycle, which can use a tight tightening device to adjust the relative position of the brake handle and the handle to suit the habits of the rider. In order to achieve the above purpose, this office The proposed improvement of the handlebar of the folding bicycle is arranged on the frame of a folding bicycle. The improvement of the handlebar mainly includes a handlebar flat tube and a standpipe. The two ends of the handlebar flat tube are respectively provided with a handle, and Each handle is an extension set with a brake handle; the bottom of the 2 tubes has a folding joint to be connected to the frame of the folding bicycle, and the top of the M242448 vertical tube is equipped with a clamping device to hold and relax the bicycle Fourth, the implementation method In order to allow your review committee to better understand the technical content of this creation, a preferred embodiment is specifically described below. Please refer to Figure 2 for the development of the folding bicycle The state diagram shows that the bottom of the handlebar riser 23 of the folding bicycle 2 has a folding joint 24 connected to the overall frame, and a clamping device 25 is installed on the top of the riser 23. This embodiment The handlebar flat tube is located in the clamping device, which can be held immovably and can also be rotated by loosening the clamping device 25. Please refer to FIG. 5 for a schematic perspective view of the handlebar of this embodiment. The device 25 is an open beam ring 251 connected to the top of the handlebar 23 of the handlebar, and bolts 252 penetrate through the clips 253 on both sides of the beam ring 251, and the upper end of the bolt 252 is hinged with an eccentric locking handle 254, and It constitutes a device commonly referred to as a cam handle. Because the edge of the hinge point of the eccentric locking handle 254 is eccentric relative to the hinge shaft, as long as the eccentric locking handle 254 is pulled, the bolt 252 can be tightened or loosened. When the 252 is clamped, the beam ring 251 will clamp the handlebar flat tube 26, otherwise it will loosen the handlebar flat tube 26. Of course, the clamping device can also be a nut tightening bolt 252 as shown in FIG. The clamping ring 25 1 ′ is clamped or loosened. The clamping device 25 can be selected to be in a clamped or relaxed state by operation, so it can be called an optional operation clamping device. The hinge of the folding joint 24 at the bottom of the standpipe 23 forms an oblique angle with respect to the frame. The inclined angle is such that after the standpipe 23 is folded down, the handlebar flat pipe 26 is approximately the same as the front wheel 21 and the rear wheel 22 Equality is accurate. In addition, the handlebar flat tube 26 may be a zigzag flat tube as shown in the first embodiment, or may be a handlebar flat tube 26 as shown in FIG. 6, a straight tube, and two of the handlebar flat tube 26 The end systems are respectively provided with -handle 27, and each -handle 27 and extension group is provided with a brake handle 28.
At圖2係表示車把平管％被夾緊裝置25夾緊的使用狀 悲，倘若夾緊裝置25欲放鬆束環251，則此時可轉動車把 平e 26以使煞車手柄28轉到手柄27的下方或上方。 /當將車把的賢管23向下折疊時，請參閱圖3,顯示折 i後車把平f 26與前輪21大致平行，但煞車手柄28仍與 手柄27處於水平位置，故接著可藉由放鬆夾緊裝置城 調整煞車手柄28的角度，而形成如圖4所示之收納狀態， 即手柄27和煞車手柄28處於一上一下的位置，如此一 來三將可減少折疊後車把所佔據的空間，並在當後輪Μ 朝者車把方向收攏時’能使其與前輪21更緊湊的併攏。 當然’若後輪22朝著車把反方向收攏時，折疊自行車2折 疊後的體積也會因為將原本突出的煞車手柄28轉動後而 具有較小的體積，實為一大進步。 上述實施例僅係為了方便說明而舉例而已，本創作 所主張之權利範圍自應以中請專利範圍所述為準，而非 僅限於上述實施例。 五、圖式簡單說明 圖1係習知折疊自行車之車把折疊後之折疊狀態圖。 圖2係本創作較佳實施例折疊自行車之展開狀態圖。 圖3係本創作較佳實施例之車把折疊後之折疊狀態圖。 圖4係本創作較佳實施例車把平管轉動後之折疊狀態圖。 M242448 圖5係本創作較佳實施例車把之立體示意圖。 圖6係本創作之車把改良之另一實施態樣。 圖號說明 折疊自行車1 前輪11 後輪12 豎管13 折疊接頭14 車把平管15 手柄16 煞車手柄17 折疊自行車2 前輪21 後輪22 豎管23 折疊接頭24 夾緊裝置25 束環251 螺栓252 夾片253 偏心鎖緊柄254 車把平管26 手柄27 煞車手柄28At Figure 2 shows the use of the handlebar flat tube% clamped by the clamping device 25. If the clamping device 25 wants to loosen the ring 251, the handlebar flat e 26 can be turned at this time to turn the brake handle 28 to Below or above the handle 27. / When the handlebar 23 is folded down, please refer to FIG. 3, showing that the rear handlebar flat f26 is substantially parallel to the front wheel 21, but the brake handle 28 is still in the horizontal position with the handle 27, so you can then borrow The angle of the brake handle 28 is adjusted by loosening the clamping device city to form a storage state as shown in FIG. 4, that is, the handle 27 and the brake handle 28 are in an up and down position. In this way, the number of folding rear handlebars can be reduced. It occupies space and can be brought closer to the front wheel 21 when the rear wheel M is folded toward the handlebar. Of course, if the rear wheel 22 is folded in the opposite direction to the handlebar, the volume of the folded bicycle 2 after folding will also have a smaller volume by turning the brake lever 28 that originally protrudes, which is a great improvement.
