Abstract
Description
本発明は、列車に持ち込む事を目的とした、折り畳み自転車に関する。 The present invention relates to a folding bicycle intended to be brought into a train.
一般に有る折り畳み自転車は、軽量・コンパクトを優先し、折り畳んだ時の形状は優先順位が低い様で、軽量・コンパクトに折り畳めても、手間の掛かる折り畳み作業や、折り畳み後の各部品の突起、汚れ易い部品の露出等、列車内に持ち込むには他の乗客に気兼ねする覚悟が必要で、列車通勤等の使用は難しいものがあった。 In general, folding bikes give priority to light weight and compactness, and the folded shape seems to have a low priority. In order to bring parts into the train, such as the easy exposure of parts, it was necessary to be prepared for other passengers.
解決しようとする問題点は、折り畳み動作の複雑さと、列車内に持ち込む場合の折り畳時の突起の有る形状と、汚れ易い部品の露出。
カバーを掛ける方法も有るが、その作業に手間が掛かる事と、カバーでは列車内が混雑している場合、突起物を防ぎきれない事。
折り畳み時の運搬で、通常のキャリーバックの様な車輪では、騒音や振動が大きいため、折り畳み時にも自転車の車輪を利用する事。
普段、自転車に乗らない人にも乗ってもらえる様、走行時のフラ付を抑える事。The problems to be solved are the complexity of the folding operation, the shape with the projections when folding into the train, and the exposure of easily contaminated parts.
There is a way to hang the cover, but it takes time to do the work, and if the cover is crowded in the train, it can not prevent the projection.
Wheels like normal carry-backs are used for carrying when folded, so noise and vibration are great, so use bicycle wheels when folding.
To prevent people who don't usually ride bicycles from riding, keep the hula off when driving.
前輪に小径タイヤを持ち、後輪はＤＶＤ程の極小タイヤを左右に持ち、車体フレームと後輪の一部分以外を、備え付けのケースに収納した時、キャリーバッグの様に見える折り畳み自転車。
キャリーバッグを列車内に持ち込む事は、日常の事で他の乗客に気兼ねする必要は無くなる。A folded bicycle that looks like a carry bag when the front wheels have small tires and the rear wheels have very small tires, such as a DVD, on the left and right, and the body frame and parts of the rear wheels are stored in the provided case.
Bringing a carry bag into the train eliminates the need to worry about other passengers in everyday situations.
折り畳むために、フレームは９ヵ所のピボットを持ち、これらのピボットの回転軸の方向は全て、直進時の車輪の回転軸と同方向に配置し、ヘッドチューブとシートチューブはピボットを取る場所がチューブの右側と左側に別れ、片側にダウンチューブ、もう片方にトップチューブを、横から見て交差する配置とする。
まず、下端の片側にピボットを持ち、下端とは反対側でチューブの幅一本分車体後方にオフセットした場所にブラケットを設け、そこに上端のピボットを取ったヘッドチューブのキャスター角を選択。
ヘッドチューブ下端と同側に、上端のピボットを持ち、ヘッドチューブ上端と同側に下端のピボットを持つシートチューブを、ヘッドチューブの角度より、シートチューブ上端のピボット付近で、チューブの幅一本分立たせる。この意味は、平行の場合、折り畳んだ時駆動系のギアと干渉してしまう事と、開いた時平行以上に開いてしまい都合が悪いためで、このシートチューブとヘッドチューブは上方から見て一直線に配置する。
両端にピボットを持ち、中央より下側の位置で、平行にチューブの幅一本分下げられた形状のダウンチューブで、ヘッドチューブ上端のピボットとシートチューブ下端のピボットを結び、両端にピボットを持つトップチューブで、ヘッドチューブ下端のピボットとシートチューブ上端のピボットを結ぶ。
トップチューブとダウンチューブはクロスするので、そのクロスする部分にもピボットを設けトップチューブとダウンチューブを結ぶ。
また、シートチューブとトップチューブに１８０度折り返す箇所を設けるが、シートチューブの場合、折り畳んだ時、トップチューブとダウンチューブのクロスするピボットの中心を支点に、トップチューブが畳まれ、ダウンチューブの上部のラインと同一線上に位置する。この時のトップチューブとシートチューブを繋ぐピボットの中心が一致する場所を計算し、シートチューブが１８０度折り返す、二箇所のピボットを設けシートチューブを上下二つに分離する。
トップチューブの場合、折り畳んだ時、ヘッドチューブ上部とダウンチューブを繋ぐピボットの中心を支点に、ヘッドチューブよりチューブ一本分後方に畳まれる。この時のトップチューブとダウンチューブを繋ぐピボットの中心が一致する場所を計算し、トップチューブが１８０度折り返す、二箇所のピボットを設けトップチューブを前後二つに分離し、シートをハンドル方向ではなく後輪方向へ折り畳む。
このシートチューブとトップチューブの１８０度折り返す箇所に、ロック機構を設けるが、１８０度折り返す箇所のチューブの内側に、シートピラーと同径のチューブをばねの力で押し込むタイプとし、ロック解除はワイヤーでチューブを引き抜く方式とする。In order to fold, the frame has nine pivots, the rotation axes of these pivots are all arranged in the same direction as the rotation axis of the straight wheel, and the head tube and seat tube are the places where the pivots are taken The right side and the left side are separated, and the down tube on one side and the top tube on the other side cross each other when viewed from the side.
First, hold the pivot on one side of the lower end, and install a bracket on the opposite side of the lower end to the rear of the vehicle by the width of the tube, and select the caster angle of the head tube that took the upper end pivot.
A seat tube with a pivot at the upper end on the same side as the lower end of the head tube, and a pivot at the lower end on the same side as the upper end of the head tube. Stand up. This means that in the case of parallel, it interferes with the gear of the drive system when folded, and it is inconvenient because it opens more than parallel when opened, so the seat tube and head tube are straight when viewed from above. To place.
A down tube that has pivots at both ends and is lowered by one tube width in parallel at a position below the center. Connect the pivot at the top of the head tube and the pivot at the bottom of the seat tube, and have the pivots at both ends. At the top tube, connect the pivot at the lower end of the head tube and the pivot at the upper end of the seat tube.
Since the top tube and the down tube cross, a pivot is also provided at the crossing portion to connect the top tube and the down tube.
In addition, the seat tube and the top tube are provided with a portion that is folded 180 degrees. When the seat tube is folded, the top tube is folded around the center of the pivot that the top tube and the down tube cross, and the top of the down tube Located on the same line as At this time, a place where the centers of the pivots connecting the top tube and the seat tube coincide with each other is calculated, and the seat tube is folded 180 degrees, and two pivots are provided to separate the seat tube into two.
In the case of the top tube, when folded, the tube is folded backward by one tube from the head tube, with the pivot center connecting the top of the head tube and the down tube as a fulcrum. Calculate the place where the center of the pivot connecting the top tube and the down tube at this time coincides, and the top tube is folded 180 degrees. Fold in the direction of the rear wheel.
A lock mechanism is provided at the position where the seat tube and the top tube are folded back 180 degrees, but the tube with the same diameter as the seat pillar is pushed into the inside of the tube at the position where the sheet tube is folded back 180 degrees by the spring force. Use a method of pulling out the tube.
同じ長さの二本のロッドを後方から見て上下平行に置き、それぞれのロッドの中央と両端に、車体前後方向に中心線を持つピボットを設け、中央のピボット付近を車体後方に平行を保ったまま湾曲させる。
この二本の湾曲した平行ロッドの、中央のピボットをチューブで上下に繋ぎ、それを前方に折り曲げ延長しダウンチューブと固定する。
車体フレームと繋がった上下二本の湾曲した平行ロッドの両端のピボットを、それぞれチューブで上下に繋ぎ後方に折り曲げた物が、左右のチェーンステーになる。
この平行な二本のロッドは車体がバンクした時、後輪の両輪は地面に接地しながら、左右のチェーンステー及び車輪は、車体のバンク角と同じ傾きをするためのもので、湾曲させる意味は、駆動で用いるチェーンと、その駆動を受けるギア等を支えるチューブとの干渉を避けるため。Two rods of the same length are placed parallel to each other when viewed from the rear, and pivots having a center line in the longitudinal direction of the vehicle are provided at the center and both ends of each rod, and the vicinity of the central pivot is kept parallel to the rear of the vehicle. Keep it curved.
The center pivot of these two curved parallel rods is connected up and down with a tube, and it is bent forward and fixed to the down tube.
The left and right chain stays are obtained by connecting the pivots at both ends of the upper and lower curved parallel rods connected to the body frame up and down with tubes and bending them backward.
These two parallel rods mean that when the car body is banked, both the rear wheels touch the ground and the left and right chain stays and wheels are tilted to the same angle as the bank angle of the car body. In order to avoid interference between the chain used for driving and the tube that supports the gear that receives the driving.
前項の平行な上下二本のロッドの上下を繋ぐ、スプリングとダンパーを持つ。その場所は、後に通すシャフトと干渉せずストロークを出来るだけ大きく取れる場所で、後方から見て上側のロッドの左側の湾曲した部分と、下側のロッドの左端を、同様に後方から見て上側の右側の湾曲した部分と下側のロッドの右端を、それぞれスプリングとダンパーで繋ぐ。
この意味は、走行時の車体のフラ付きを抑える事と停車時の自立。It has a spring and a damper that connect the top and bottom of the two parallel upper and lower rods. The place is a place where the stroke can be taken as much as possible without interfering with the shaft to be passed through, and the curved part on the left side of the upper rod when viewed from the rear and the left end of the lower rod are similarly viewed from the rear and the upper side. Connect the curved part on the right side and the right end of the lower rod with a spring and a damper, respectively.
This means restraining the body from fluttering while driving and independence when stopping.
ペダルのクランクアームは、シートチューブに設けた四つのピボットの内、最下部と、最下部から二番目のピボットの間に固定した左右のアームで支える事で、折り畳み時にシートチューブ最下部のピボットを支点に回転し、前輪との干渉を避ける。
このため、左右のアームはフロントフォークと同じ幅かそれ以上にし、支点となるシートチューブ最下部のピボットと同軸にチェーンホイールからチェーンで動力を受けるスプロケットを設ける。The crank arm of the pedal is supported by the left and right arms fixed between the bottom pivot and the second pivot from the bottom of the four pivots provided on the seat tube. Rotate to the fulcrum and avoid interference with the front wheels.
For this reason, the left and right arms have the same width as or more than the front fork, and a sprocket that receives power from the chain wheel from the chain wheel is provided coaxially with the pivot at the bottom of the seat tube as a fulcrum.
ペダルからの動力を受け、左右の後輪を駆動しながら、車体のバンクに対応するため、バンク時、車体と後輪を支える上下に平行なロッド以後とは、別々の動きをするが、車体がバンクしても唯一位置関係の変化が無い、上下に平行なロッドの、中央のピボットの回転の中心を、上下に結ぶ線上から動力を受け、左右の後輪を駆動する。
シートチューブ最下部のギアと同軸のギアを、後方から見て、上下に平行なロッドの、中央のピボットの回転の中心を上下に結ぶ線上に設ける。同じ線上の後方にその駆動を受けるギアを設け、内側のドラムで固定し、ドラムはドラムの外径と内径を同じくするベアリングを介してダウンチューブに固定する。
ドラムの外周のギアから受けた動力を左右の後輪へ伝えるため、ドラムの回転の中心にシャフトを通し左右に伝えるが、シャフトとドラムの接続は、１２時・３時・６時・９時の場所に放射方向の回転軸のピボットを持つリングを用いて、１２時と６時の場所はドラムと、３時と９時の場所はシャフトと結び、１２時と６時のピボットの回転軸は、直立時後方から見て、上下に平行なロッドの、中央のピボットの回転の中心を上下に結ぶ線上に設ける。
同じリングとドラムを左右に設け、１２時と６時の場所はドラムと、３時と９時の場所はシャフトと結び、１２時と６時のピボットの回転軸は、直立時後方から見て、上下に平行なロッドの、左右それぞれのピボットの回転の中心を上下に結ぶ線上に設け、ドラムは後輪用チェーンホイールとベアリングを介してチェーンステーに固定する。In order to respond to the bank of the vehicle body while receiving the power from the pedal and driving the left and right rear wheels, the bank moves separately from the upper and lower parallel rods that support the vehicle body and the rear wheel. Even if it is banked, there is no change in the positional relationship, and the right and left rear wheels are driven by receiving power from a line connecting the center of rotation of the central pivot of the rods parallel to the top and bottom.
A gear coaxial with the gear at the lowermost part of the seat tube is provided on a line connecting the center of rotation of the central pivot of the rod parallel to the vertical when viewed from the rear. A gear that receives the drive is provided at the rear on the same line, and is fixed by an inner drum, and the drum is fixed to the down tube through a bearing having the same outer diameter and inner diameter of the drum.
In order to transmit the power received from the outer gear of the drum to the left and right rear wheels, the shaft is transmitted to the left and right through the center of rotation of the drum, but the connection between the shaft and the drum is 12 o'clock, 3 o'clock, 6 o'clock, 9 o'clock Using the ring with the pivot of the radial axis of rotation at the location of the shaft, the 12 o'clock and 6 o'clock locations are connected to the drum, the 3 o'clock and 9 o'clock locations are connected to the shaft, and the 12 o'clock and 6 o'clock pivot shafts Is provided on a line connecting the center of rotation of the central pivot of the rod parallel to the top and bottom when viewed from the rear when standing up and down.
The same ring and drum are provided on the left and right sides, and the 12 o'clock and 6 o'clock locations are connected to the drum, the 3 o'clock and 9 o'clock locations are connected to the shaft, and the pivot axes of the 12 o'clock and 6 o'clock pivots are viewed from the rear when standing upright. The rod parallel to the top and bottom is provided on a line connecting the center of rotation of the left and right pivots vertically, and the drum is fixed to the chain stay via the rear wheel chain wheel and the bearing.
変速機を用いる場合、通常の多段ギアにチェーンを移動させて変速するのではなく、二輪車や四輪車に用いられている、二軸式変速機とする事で、変速時のチェーンの脱落を防ぐ。
ギアボックスをペダルのクランクアーム支持部に固定し、一軸目をクランクアームの回転軸と同軸とし、二軸目をその後方下側に置く。
二軸目からの出力をギアボックス外側のダウンチューブとは反対側に設けたギアで行うが、このままでは回転が逆周りなため、ギアボックスからの出力ギアにもう一枚のギアをあて、シートチューブ最下部のピボットと同軸のスプロケットとの、位置を合わせるための小径のチェーンホイールも設け、短いシャフトで繋ぎチェーンで駆動する。When using a transmission, instead of shifting the chain by moving it to the usual multi-stage gear, the two-shaft transmission used in two-wheeled and four-wheeled vehicles can be used to prevent the chain from dropping off during shifting. prevent.
The gear box is fixed to the crank arm support portion of the pedal, the first axis is coaxial with the rotation axis of the crank arm, and the second axis is placed on the lower rear side.
The output from the second axis is performed with the gear provided on the opposite side of the down tube outside the gear box, but the rotation is reversed in this state, so another gear is applied to the output gear from the gear box, and the seat A small-diameter chain wheel is also provided to align the position of the pivot at the bottom of the tube and the coaxial sprocket.
左右の後輪はそれぞれコグとベアリングを介して左右のチェーンステーに取り付け、後輪外側にコグと同軸のスプロケットを設ける。
チェーンステーと結ぶ左右の後輪の位置は、直立時後方から見て、上下に平行な二本のロッドの、左右それぞれのピボットの回転の中心を上下に結ぶ線の外側では、バンク時にコーナー外側の車輪が上がりコーナー内側の車輪が下がるため、結果バンク角が浅くなる。それを補うため、上下に平行な二本のロッドとシャフトが、より大きく傾斜する事になり、不必要にドラムや中央のベアリングの径を大きく取る事になり、望ましくない。
逆に、内側ではバンク時にコーナー外側の車輪が下がりコーナー内側の車輪が上がるため、結果バンク角が深くなる。それを補うため、上下に平行な二本のロッドとシャフトの傾斜が小さくなる。
この事により、後輪は車輪を後方から見て左右に二分する中心線と、上下に平行な二本のロッドの、左右それぞれのピボットの回転の中心を上下に結ぶ線と同軸上に置くか、それより内側に置く様にチェーンステーを配置し、チェーンで結ぶチェーンホイールとスプロケットは、直立時上側から見て同一線上の位置に置く。The left and right rear wheels are attached to the left and right chain stays via cogs and bearings, respectively, and a sprocket coaxial with the cogs is provided outside the rear wheels.
The position of the left and right rear wheels that connect to the chain stay is the outside of the corner when banking, outside the line connecting the center of rotation of the left and right pivots of the two rods parallel to the top and bottom when viewed from the rear when standing upright. As the wheel rises and the wheel inside the corner falls, the resulting bank angle becomes shallower. In order to compensate for this, the two rods and shafts parallel to the top and bottom are inclined more greatly, which unnecessarily increases the diameter of the drum and the center bearing, which is not desirable.
On the contrary, on the inner side, the wheel outside the corner falls and the wheel inside the corner rises during banking, resulting in a deeper bank angle. To compensate for this, the inclination of the two rods parallel to the top and bottom and the shaft is reduced.
As a result, the rear wheel should be placed coaxially with the center line that bisects the wheel left and right when viewed from the rear, and the line that connects the center of rotation of the left and right pivots of the two rods parallel to the top and bottom. Place the chain stay so that it is placed on the inner side, and the chain wheel and sprocket to be connected with the chain should be placed on the same line as seen from the upper side when standing upright.
シートピラーは、シートチューブの上端でシートピラーのサドル側が、若干前方にオフセットされた形状にし、その境目でシートピラーを分離、上側と下側が重なる中心で回転する様にする。上下のチューブの境目は平らに塞ぎ、間にベアリングのボールの様な物を挟み、サドルの位置決めをする。
サドルを回転させた時、シートピラー下側は回転しようとする軸がずれているため回転できず、シートピラー上側が回転する事になり、サドルを１８０度反転させた時初めて、シートピラーが一直線となり、シートピラーをシートチューブへ押し込む事ができる。
また、シートチューブの１８０度折り返す上の部分の内側下部に、ばねで支持されたシートピラーと同径の短いチューブを置き、これにワイヤーを繋げる。サドルを下げた時シートピラーが下がる事で、短いチューブが下がりワイヤーが引かれ、ハンドルのステム部分や、シートチューブとトップチューブの折り返す部分のロックが外れ、決して走行時に外れることは無い設定で、折り畳み動作の簡素化を図る。The seat pillar has a shape in which the saddle side of the seat pillar is slightly offset at the upper end of the seat tube, and the seat pillar is separated at the boundary, and is rotated at the center where the upper side and the lower side overlap. The border between the upper and lower tubes is closed flat, and a saddle is positioned by inserting an object such as a ball of the bearing between them.
When the saddle is rotated, the lower side of the seat pillar cannot be rotated because the axis to be rotated is misaligned, and the upper side of the seat pillar will rotate. Only when the saddle is turned 180 degrees, the seat pillar is not aligned. Thus, the seat pillar can be pushed into the seat tube.
Also, a short tube having the same diameter as the seat pillar supported by the spring is placed on the inner lower part of the upper part of the seat tube that is folded back 180 degrees, and a wire is connected thereto. When the saddle is lowered, the seat pillar is lowered, the short tube is lowered, the wire is pulled, the stem part of the handlebar and the part where the seat tube and the top tube are folded back are unlocked, and it will never come off during driving, To simplify the folding operation.
折り畳んだ時のバッグの様に見えるケースは、シートチューブ後方に取り付け、後から見て中央から左右に開閉する。サドルを回転させた時ロックが外れ、ばねにより開く様にし、折り畳み動作の簡素化を図る。
このケースはシートチューブに取り付ける事で、折り畳む時シートチューブは上下及び前後に向きを変えるので、ケースの開放部も折り畳み時は、前方になり、前輪とペダルの駆動部分、チェーンやサドルをケースに収納する事ができる。The case that looks like a bag when folded is attached to the rear of the seat tube and opened and closed from the center to the left and right as viewed from the rear. When the saddle is rotated, it is unlocked and opened by a spring to simplify the folding operation.
By attaching this case to the seat tube, the seat tube changes direction up and down and back and forth when it is folded, so when the case opening is folded, it will be forward and the front wheel and pedal drive part, chain and saddle will be attached to the case. Can be stored.
ハンドルは、ステム部のチューブ幅一本分前方にオフセットした場所に、１８０度折り返す部分を設け、その部分には車体前方に回転し下向きに折り畳まれる様ばねを設ける。
ロック機構は、折り返した時干渉しない程度間隔を開け、ステムの上側に設け、シートチューブ同様、ステムに開けた穴にばねの力でチューブを押し込むタイプとし、ロック解除もワイヤーでチューブを引き抜く方式とする。
ロック機構の両脇に固定した左右のアームは、折り畳んだ時フロントフォークと干渉しない様、上部で湾曲させその先端にハンドルのグリップ部分を取り付ける。The handle is provided with a portion folded back 180 degrees at a position offset forward by one tube width of the stem portion, and a spring is provided at that portion so as to be rotated forward and folded downward.
The locking mechanism is spaced apart so as not to interfere when folded, and is provided on the upper side of the stem. Like the seat tube, it is a type that pushes the tube into the hole made in the stem with the force of the spring, and the lock is pulled out with a wire To do.
The left and right arms fixed on both sides of the lock mechanism are bent at the top so that they do not interfere with the front fork when folded, and the handle grip is attached to the tip.
ヘッドチューブ上方で、ダウンチューブのピボットとは反対側に、折り畳み時の運搬用にグリップを設ける。 A grip is provided above the head tube on the side opposite to the pivot of the down tube for transport during folding.
