Description
【考案の詳細な説明】 （イ）産業上の利用分野 この新案は折り畳み式自転車に関する。[Detailed Description of the Invention] (a) Industrial Application Field This new model relates to a folding bicycle.
（ロ）従来の技術 従来の折り畳み式自転車は、折り畳み操作が容易でなく折り畳みに時間がかかる し、折り畳み後の容積が大きいので携帯に不便である。(B) Conventional technology The conventional folding bicycle is inconvenient to carry because the folding operation is not easy and it takes time to fold, and the volume after folding is large.
（ハ）新案が解決しようとする問題点 この新案は、折り畳み操作が容易で、折り畳みに時間がかからないようにし、折 り畳み後の容積を小さくして携帯しやすくすることを目的とした。(C) Problems to be solved by the new model This new model aims to facilitate the folding operation so that it does not take much time to fold, and to make it easier to carry by reducing the volume after folding.
（ニ）問題点を解決するための手段 この新案を図面にもとずいて説明すると、第一図は 折畳み式自転車の側面図で 、携帯に便利なようにするためには、折り畳み後の容積を小さくすることが必要 で、そのためには、車輪を小型にし座席を低くする必要がある。車輪を小型にし ても、安定に乗車出来るように３輪車にし、座席が低くても自転車をこぐことが できるようにペダルは前車輪の前に位置し、２つのチェーンホイールと２つのチ ェーンを有している。チェーンホイール固定用前パイプ２０の前端には前チェー ンホイール９、後端には後チェーンホイール１０がとりつけられ、チェーンホイ ール固定用後パイプ２１の前端には後チェーンホイール１０、後端には後輪車軸 １５が取り付けられている。チェーンホイール固定用前パイプ２０は、回転軸１ ３によりヘッドパイプ３にとりつけられている。チェーンホイール固定用前パイ プ２０とチェーンホイール固定用後パイプ２１は折り畳みができるよう、後チェ ーンホイール１０の軸を中心に回転できる。走行中は、チェーンホイール固定用 パイプが回転しないように、後チェーンホイール固定用中パイプ１９が係止軸１ ４により、ヘッドパイプ３に固定されている。サドル６は折り畳み操作を容易に するため、サドル用回転軸１６によりヘッドパイプ３に取り付けられ、他端はサ ドル底部の嵌合凹み１７とバックホーク４の中間にある係止バー１８により固定 されている。(D) Means for solving the problem This new model will be described with reference to the drawings. The first figure is a side view of a folding bicycle, and the volume after folding is shown in order to make it convenient to carry. Needs to be smaller, which requires smaller wheels and lower seats. Even if the wheels are small, it is a three-wheeled vehicle for stable riding, and the pedals are located in front of the front wheels so that the bicycle can be pedaled even when the seats are low. Two chain wheels and two chains are provided. have. The front chain wheel 9 is attached to the front end of the front pipe 20 for fixing the chain wheel, and the rear chain wheel 10 is attached to the rear end thereof. The rear chain wheel 10 is attached to the front end of the rear pipe 21 for fixing the chain wheel and the rear chain wheel is attached to the rear end thereof. The rear wheel axle 15 is attached to the. The front pipe 20 for fixing the chain wheel is attached to the head pipe 3 by a rotary shaft 13. The front pipe 20 for fixing the chain wheel and the rear pipe 21 for fixing the chain wheel can be rotated about the axis of the rear chain wheel 10 so that they can be folded. The rear chainwheel fixing middle pipe 19 is fixed to the head pipe 3 by the locking shaft 14 so that the chainwheel fixing pipe does not rotate during traveling. To facilitate the folding operation, the saddle 6 is attached to the head pipe 3 by a saddle rotating shaft 16, and the other end is fixed by a fitting bar 17 at the bottom of the saddle and a locking bar 18 in the middle of the back hawk 4. ing.
係止軸１４の脱着機構の詳細やサドル６の係止バーからの離脱防止機構は省略す る。The details of the attachment / detachment mechanism of the locking shaft 14 and the mechanism for preventing the saddle 6 from coming off the locking bar are omitted.
（ホ）作用 車輪が小さくても、３輪車のため安定で、走行中でも停止中でも車輪が倒れるこ とがない。車輪が小さいので回転数を多くする必要があるが、２つのチェーンホ イールがあるので、ペダル８の回転数を従来の自転車並みにしても前チェーンホ イール９と、後チェーンホイール１０のギヤレイショを適切に選ぶことによって ホイールの直径を大きくすることなく、後車輪２の回転数を多くして従来の自転 車並みの速度で走ることができる。次に自転車の折り畳み方について説明すると 、まずサドル６を少し持ち上げ、サドル底部の嵌合凹み１７を係止バー１８から はずし、背もたれ７を持って少し後方に倒し、サドル６がサドル用回転軸１６に より回転して、サドル６の後端が後チェーン１２にタッチしたら（図では省略し ているが、チェーンはカバーされているのでサドルが直接チェーンとタッチする ことはない）、背もたれ７をハンドル５の方に倒してバックホーク４を折り畳む 。(E) Action Even if the wheels are small, they are stable because they are three-wheeled vehicles, and the wheels do not fall over while the vehicle is running or stopped. Since the wheels are small, it is necessary to increase the number of rotations, but since there are two chain wheels, the gear ratio of the front chain wheel 9 and the rear chain wheel 10 can be properly adjusted even if the rotation speed of the pedal 8 is similar to that of a conventional bicycle. By selecting it, it is possible to increase the number of rotations of the rear wheel 2 and run at a speed comparable to that of a conventional bicycle without increasing the diameter of the wheel. Next, how to fold the bicycle is explained. First, lift the saddle 6 a little, remove the fitting recess 17 on the bottom of the saddle from the locking bar 18, hold the backrest 7 and tilt it a little backward, and the saddle 6 rotates the saddle rotation shaft 16 When the rear end of the saddle 6 touches the rear chain 12 by rotating (there is no illustration in the figure, the chain is covered, so the saddle does not touch the chain directly), then handle the backrest 7 Fold back hawk 4 by tilting it towards 5.
次に係止軸１４をはずし、後チェーンホイール固定用中パイプ１９とハンドル５ を持って上方へ持ち上げると２つのチェーンは後チェーンホイール１０の軸を中 心に回転して折り畳まれる。このように極めて容易にスピーデイに、持ち運び易 い小型に折り畳むことができる。第三図は自転車を折り畳んだ場合の側面図。第 五図は自転車を折り畳んだ場合の斜視図。第六図は折り畳んだ自転車に上からカ バー２２を掛けた場合の斜視図で、ハンドル５を持って道路をころがしても、ま た持ち上げて運んでもよい。サドル底部の嵌合凹み１７は多数あって係止バー１ ８との位置を変えることによって背丈の違う場合の調節ができる。Then, the locking shaft 14 is removed, and the rear chain wheel fixing middle pipe 19 and the handle 5 are lifted upward, and the two chains are folded around the shaft of the rear chain wheel 10 as a center. In this way, it can be folded very quickly, easily, and in a compact size that is easy to carry. Figure 3 is a side view of the bicycle when folded. Fig. 5 is a perspective view when the bicycle is folded. FIG. 6 is a perspective view of the folded bicycle with the cover 22 hung from above, and the handle 5 may be rolled on the road or lifted and carried. There are many fitting recesses 17 on the bottom of the saddle, and by adjusting the position with respect to the locking bar 18, adjustment can be performed when the height is different.
（ヘ）実施例 折り畳み式携帯自転車で、第四図、第五図、第六図は実施例をしめす。(F) Example An example of a foldable portable bicycle is shown in FIGS. 4, 5, and 6.
（ト）新案の効果 この新案は以上説明したように、極めて簡単な操作で、容易に、スピーデイに、 小型に、自転車を折り畳むことができる。またカバーも上から被せるだけで簡単 であり、外観もスマートで持ち運びも極めて容易である。また何処でも椅子とし て使用することもできる。３輪車であるから老人が使用しても安全である。(G) Effect of the new model As described above, this new model can fold a bicycle easily, speedily, and compactly with an extremely simple operation. In addition, the cover is easy to cover from above, and the appearance is smart and easy to carry. It can also be used as a chair anywhere. Since it is a three-wheeled vehicle, it is safe for the elderly to use.
