Abstract
【課題】乗り手のズボンを引っかけたり、その他の用具を打ったりするのをなくすことができる折り畳み自転車のシートチューブを提供する。
【解決手段】折り畳み自転車のシートチューブ1は、その底端2が前方になるように傾けられている。底端2の前側は、ビーム3又は補強ロッドに接続されている。底端2は、斜状の切り口とされた端面を有する。斜状の切り口とすることにより、シートチューブ1の底端2の後側部分は突き出ていない。したがって、乗り手は乗車時にズボンを引っかけることがなくなり、ズボンが裂けたり乗り手がつまずいたりするような危険が生じることがなくなる。また、シートチューブ1の底端2の後側部分が突き出ていないことから、シートチューブ1の底端2が自転車キャリヤやその他の用具を打つことがなくなり、自転車キャリヤを傷つけたり用具を破損したりすることがなくなる。
【選択図】図2The present invention provides a seat tube for a folding bicycle that can eliminate the need to catch a rider's trousers or hit other equipment.
A seat tube 1 of a folding bicycle is inclined so that a bottom end 2 thereof is in front. The front side of the bottom end 2 is connected to the beam 3 or the reinforcing rod. The bottom end 2 has an end face that is an oblique cut. By using the oblique cut, the rear portion of the bottom end 2 of the seat tube 1 does not protrude. Therefore, the rider does not catch the pants when getting on, and there is no danger of the pants tearing or the rider tripping. Further, since the rear portion of the bottom end 2 of the seat tube 1 does not protrude, the bottom end 2 of the seat tube 1 does not hit the bicycle carrier or other equipment, and the bicycle carrier is damaged or the equipment is damaged. There is no longer to do.

Description
本考案は、折り畳み自転車のフレームの構造に関し、特に、折り畳み自転車のシートチューブに関する。 The present invention relates to a structure of a folding bicycle frame, and more particularly to a seat tube of a folding bicycle.
図1に示すように、折り畳み自転車の従来のシートチューブ1aは、その底端2aが前方になるように傾けられている。底端2aの端面は略平面とされており、底端2aの前側はビーム又は補強ロッドに接続され、底端2aの後側は突き出ている。乗り手は乗車時にシートチューブ1aの底端2aの突き出ている後側部分によってズボンを引っかけるかもしれず、これは、ズボンが裂けたり乗り手がつまずいたりする原因となり得る。また、シートチューブ1aの底端2aの突き出ている後側部分は、自転車キャリヤやその他の用具に容易に接触することが可能とされ、これは、自転車キャリヤが傷ついたり用具が破損したりするのを引き起こしかねない。 As shown in FIG. 1, the conventional seat tube 1a of the folding bicycle is inclined so that the bottom end 2a is forward. The end surface of the bottom end 2a is substantially flat, the front side of the bottom end 2a is connected to a beam or a reinforcing rod, and the rear side of the bottom end 2a protrudes. When the rider gets on, the pants may be caught by the protruding rear portion of the bottom end 2a of the seat tube 1a, which may cause the pants to tear or the rider to trip. Further, the protruding rear portion of the bottom end 2a of the seat tube 1a can easily come into contact with the bicycle carrier or other equipment, which may damage the bicycle carrier or damage the equipment. Can cause.
本考案は、このような実情に鑑みてなされたものであり、乗り手のズボンを引っかけたり、その他の用具を打ったりするのをなくすことができる折り畳み自転車のシートチューブを提供することを目的とする。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a folding bicycle seat tube capable of eliminating the rider's trousers and hitting other equipment. .
本考案にかかる折り畳み自転車のシートチューブは、その底端が前方になるように傾けられて折り畳み自転車に配置され、上記底端の前側がビーム又は補強ロッドに接続されているシートチューブであって、上記底端は、前側部分及び後側部分からなる端面を有し、上記端面の後側部分が上記前側部分よりも高くなるように部分的に除去されていることを特徴としている。 The seat tube of the folding bicycle according to the present invention is a seat tube that is disposed on the folding bicycle so that its bottom end is forward, and the front side of the bottom end is connected to a beam or a reinforcing rod, The bottom end has an end surface composed of a front portion and a rear portion, and the rear portion of the end surface is partially removed so as to be higher than the front portion.
ここで、上記底端の端面は、滑らかに変化する面とされているのが望ましい。 Here, it is desirable that the end surface of the bottom end be a surface that smoothly changes.
また、上記底端の端面は、斜状の切り口とされているのが望ましい。 Moreover, it is desirable that the end surface of the bottom end has a diagonal cut.
また、本考案は、上記シートチューブを含む折り畳み自転車も提供する。 The present invention also provides a folding bicycle including the seat tube.
このような本考案にかかるシートチューブ及び折り畳み自転車においては、底端の端面が斜状の切り口であることから、シートチューブの底端の後側部分が突き出ない。 In such a seat tube and a folding bicycle according to the present invention, the rear end portion of the bottom end of the seat tube does not protrude because the end surface of the bottom end is an oblique cut end.
本考案にかかるシートチューブ及び折り畳み自転車においては、シートチューブの底端の後側部分が突き出ていないことから、乗り手が乗車時にズボンを引っかけることがなくなり、ズボンが裂けたり乗り手がつまずいたりするような危険が生じることがなくなる。また、本考案にかかるシートチューブ及び折り畳み自転車においては、シートチューブの底端の後側部分が突き出ていないことから、シートチューブの底端が自転車キャリヤやその他の用具を打つことがなくなり、自転車キャリヤを傷つけたり用具を破損したりすることがなくなる。 In the seat tube and the folding bicycle according to the present invention, since the rear portion of the bottom end of the seat tube does not protrude, the rider does not catch the pants when getting on, and the pants are torn or the rider is stumbled. There is no danger. Further, in the seat tube and the folding bicycle according to the present invention, since the rear side portion of the bottom end of the seat tube does not protrude, the bottom end of the seat tube does not hit the bicycle carrier or other equipment. Will not hurt or damage the equipment.
以下、本考案を適用した具体的な実施の形態について図面を参照しながら詳細に説明する。 Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

First Embodiment As shown in FIG. 2, the seat tube 1 of the folding bicycle is inclined so that the bottom end 2 is forward, and the front side of the bottom end 2 is connected to the beam 3. Further, the end surface of the bottom end 2 is partially removed so that the rear side portion is higher than the front side portion. Specifically, the end surface of the bottom end 2 is a surface that changes smoothly, and it is particularly desirable that the bottom end 2 has an oblique cut surface.
底端2の端面が斜状の切り口であることから、シートチューブ1の底端2の後側部分は突き出ていない。したがって、乗り手は乗車時にズボンを引っかけることがなくなり、ズボンが裂けたり乗り手がつまずいたりするような危険が生じることがなくなる。また、シートチューブ1の底端2の後側部分が突き出ていないことから、シートチューブ1の底端2が自転車キャリヤやその他の用具を打つことがなくなり、自転車キャリヤを傷つけたり用具を破損したりすることがなくなる。 Since the end surface of the bottom end 2 is an oblique cut, the rear portion of the bottom end 2 of the seat tube 1 does not protrude. Therefore, the rider does not catch the pants when getting on, and there is no danger of the pants being torn or the rider tripping. Further, since the rear portion of the bottom end 2 of the seat tube 1 does not protrude, the bottom end 2 of the seat tube 1 does not hit the bicycle carrier or other tools, and the bicycle carrier is damaged or the tools are damaged. There is no longer to do.
第2の実施の形態
図3に示すように、折り畳み自転車のシートチューブ1は、その底端2が前方になるように傾けられている。底端2の前側は補強ロッド4に接続されており、底端2の端面は斜状の切り口とされている。
