Description

【０００１】
【発明の属する技術分野】
本発明は、自転車の内ブレーキと内変速機構に関するものである。
【０００２】
【従来の技術】
従来の自転車は使用目的によって、レース用、登山用、あるいは歩く代わりに使用するものなどがあり、設計上力を節約し速度を快速にしたり、または後車輪の軸の外側に外変速器（速度比が異なる変速チェーン車）を加設したりする。外変速器は全部の変速チェーン車が外に露出しているので、常にほこりで汚れが付いて、部分品の正常な作動に影響を及ぼし、使用寿命が短くなる。それで各国の業者は車輪ハブの内変速器の研究開発に重点を置いている。伝統のブレーキもハブ式で後車輪の一側に露出して手でブレーキの操作をする。それで同様にほこりに汚されてだんだんその性能が悪くなる。そのためにハブの中に作られる内変速器が発明されるようになった。
【０００３】
それですでに知られているハブ内変速器と内ブレーキの間には内変速器の逆方向回転によりブレーキを連動させる方式でブレーキに車輪を止める効果を発生する。これらの技術に関しては米国の特許第４０５９０２８号、第４０６３４６９号、第４１９１８２号、第４１４７２４３号、第４１４７２４４号、第４１６０３９３号、第４１７９９５３号、第４２４０５３３号、第４３２３１４６号、第４６５１８５３号、第４７２１０１３号、などに公開されるものがある。
【０００４】
それらの文献の中で一種のＣＯＡＳＴＲＢＲＡＫＥがあるが、大体内変速器の逆方向動力出力でブレーキを連動して自転車を止める。各発明が使用する技術と機構は設計理念の差異により相互に異なるが、その内変速器と内ブレーキの機構が複雑で理想的でないので、業者は絶えずその研究開発に従事している。
【０００５】
【発明が解決しようとする課題】
それで本発明は、内変速器と内ブレーキを手で操作できるとともに足で踏んで操作する二重コントロールできる自転車のブレーキ兼用変速装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上述の目的を達成するための本発明に記載の自転車の内ブレーキと内変速機構は、車輪のハブの中に設置される内ブレーキに環状盤を設け、この環状盤の上に複数の柱が回転可能に設置され、また複数のブレーキ片が複数の柱と固定不動のブレーキハブとの間に設置され、平時ブレーキ片はブレーキハブと接触せず、また複数の柱とも接触しない。しかし足で踏んで逆方向の動力が動力入力具から入力されると逆方向動力出力滑り環を水平に逆方向に移動させ、環状盤は回転されて柱が動かされてブレーキ片をブレーキハブに押付けてブレーキの作用を発生させる。また内ブレーキの側端蓋の外部に手動ブレーキの連動板を付けて、手の操作で連動板を定位回転させて連動板の連動塊をして環状盤を回転させれば同じようにブレーキの作用を発生させるようにする。
【０００７】
本発明の手動ブレーキの連動板が操作されると内ブレーキがブレーキの作用を発生して車輪を止めるので自転車も止められる。また足による逆方向の踏みにより、内ブレーキが同じくブレーキの作用を発生して車輪が止められるので自転車も止められる。それで本発明の自転車は両用の内ブレーキと内変速器の機構をもつ。
【０００８】
これにより、次のような性能を有している。
（１）ブレーキをコントロールする効果が鋭敏である内ブレーキ。
（２）伝達が迅速で直接に内ブレーキと内変速動力を伝達する。
（３）足と手とで別々にブレーキを操作できる二種コントロールにする。
（４）同時に足で踏んでブレーキする効能と手でブレーキする効能とをもつ内ブレーキを提供して、ブレーキで止めることを一種以上の方式でコントロールできるようにし、進んで二種相互に補助する安全な効果を得る。
【０００９】
【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。
本発明の一実施例による自転車の内ブレーキと内変速機構は図１に示すように、車輪ハブ１の中に設置され、内変速器の動力入力具１１と、逆方向動力出力滑り環１１１と、出力選択環１２と、遊星歯車１３および遊星歯車枠１３１と、内歯歯車１４と、太陽歯車組と、内ブレーキのブレーキハブ２と、複数のブレーキ片２１と環状盤３と、柱４と、側面蓋５と、内変速器出力端と内ブレーキ環状盤３との間にある中間環６と固定軸７と、変速の操縦をする平面突出車８と、複数の変速制御桿と環とで構成される。
【００１０】
動力入力具１１の出力端には斜め歯１１０が設けられ、逆方向動力送出滑り環１１１と咬み合って連動する。動力入力具１１が正回転の時は逆方向送出滑り環１１１は滑らず送出選択環１２とのみ咬み合って連動する。
図６から図８に示すように、逆方向動力送出滑り環１１１の入力端には動力入力具１１の斜め歯１１０と咬み合って連動する斜め歯１１２が設けられ、その出力端には出力選択環１２と咬み合う歯１１３および内歯歯車１４と咬み合う単方向歯１１４が設けられる。動力入力具１１が逆回転する時は、滑り環１１１は水平に移動し、出力端の歯１１３および単方向歯１１４はそれぞれ出力選択環１２および内歯歯車１４と咬み合う。
【００１１】
遊星歯車１３は遊星歯車枠１３１の上に設置され、複数の太陽歯車１５、太陽歯車１５１および太陽歯車１５２と咬み合わされ固定軸７の上で回転する。遊星歯車枠１３１の入力端には咬み合わせ部１３２が設けられ、出力選択環１２の出力端咬み合わせ部１２１と咬み合う。出力選択環１２の入力端にはもどり止め１２２が設けられ、選択により内歯歯車１４の入力端に設けられている咬み合わせ部１４１と咬み合って連動する。内歯歯車１４の入力端には別に滑り環１１１の歯１１４と咬み合う歯１４２を設ける。遊星歯車枠１３１の出力端には咬み合わせ部１３３が設けられ、中間環６の入力端内縁のもどり止め６１と相対させ、内歯歯車１４の出力端には咬み合わせ部１４３が設けられて、中間環６の入力端外縁の正方向もどり止め６２と逆方向もどり止め６５と相対させる。
【００１２】
出力選択環１２の出力端のもどり止め１２２は第１環Ａに左右されてＯＮあるいはＯＦＦになり、第１環Ａは第１制御桿Ａ１に水平に移動されて連動する。第１制御桿Ａ１は固定軸７の外周にある溝７０の中に設置され、その別端はスプリングＡ２の弾力により変速制御機構８０と連動し旋回する平面突出車８の第１環状面８Ａに沿って移動し、第１制御桿Ａ１をして第１環状面８Ａの高低の起伏により水平に第１環８を移動させて、もどり止め１２２のＯＮあるいはＯＦＦを操作する。
【００１３】
太陽歯車５、太陽歯車１５１、太陽歯車１５２をコントロールする第２環Ｂの上には別々にもどり止め１５３、もどり止め１５４、もどり止め１５５をコントロールするための三列の欠け口が設けられ、各列の欠け口の長さは異なり、それで太陽歯車のもどり止め１５３をＯＦＦにする時は、もどり止め１５４、もどり止め１５５がＯＮになり、またもどり止め１５３ともどり止め１５４がＯＦＦになる時はもどり止め１５５はまだＯＮになっているので第２環Ｂは水平移動する第２制御桿Ｂ１にコントロールされて定位旋回する。第２制御桿Ｂ１は第１制御桿Ａ１と同じように固定軸７外周の溝７０の中に設置され、その別端はスプリングＢ２の弾力により歯車Ｂ３および歯ざおＢ４との協力により平面突出車８の第２環状面８Ｂに沿って移動する。
【００１４】
中間環６は車輪ハブ１の内側面と、遊星歯車枠１３１の出力端と内歯歯車１４の出力端と内ブレーキ動力入力端との間に設置されている。
図９、図１０に示すように、その入力端の内縁にもどり止め６１をもち、遊星歯車枠１３１の出力端の咬み合わせ部に咬み合わされ、入力端の外縁に設けられている正方向もどり止め６２と逆方向もどり止め６５は選択により内歯歯車１４の出力端の咬み合わせ部１４３と咬み合い可能で、中間環６の出力端には単方向もどり止め６３が設けられ、車輪ハブ１と咬み合い連動し、出力端には雄ねじ付き筒６４が連設されし、筒６４の上には斜め歯６４１が設けられて連動滑り具９と咬み合い、連動滑り具９の移動により内ブレーキの環状盤３と連動して回転し、ブレーキをかける。
【００１５】
中間環６の入力端外縁のもどり止め６２は第３環Ｃにコントロールされて内歯歯車１４の出力端咬み合わせ部１４３の所でＯＮあるいはＯＦＦになる。第３環Ｃは水平移動する第３制御桿Ｃ１と連動して水平移動可能で、第３制御桿Ｃ１は固定軸７外周の溝７０の中に定位され、その別端はスプリングＣ２の弾力により平面突出車８の第３環状面８Ｃに沿って移動する。
【００１６】
中間環６の出力端は雄ねじ付き筒６４により連動滑り具９と連動され、逆方向に回転させた時は水平移動で内ブレーキの環状盤３と咬み合い連動して回転し、ブレーキの作用を発生する。図１１から図１７に示すように、内ブレーキの環状盤３の一側に設けられた咬み合わせ部３０は連動滑り具９の咬み合わせ部９１と咬み合って連動する。環状盤３の上には複数の可動柱４（図１および図２２に示す）が設けられ、環状盤３の外側端には少なくともひとつの連結孔３１を設けられる。手動ブレーキ連動柱３Ａの移動回転時は環状盤３を連動させて回転させ、手によるブレーキ動作を施行する。環状盤３の外周囲には固定不動のブレーキハブ２が設けられ、ブレーキハブ２と環状盤３に設けられた柱４との間に複数のブレーキ片２１が設けられる。ブレーキ片２１は図２１に示すようにその一端が定位され、他端は柱４に押されて外に移動しブレーキハブ２と摩擦を生じる。環状盤３には復位スプリング２２が設けられて環状盤３が回転してブレーキしたあと、自動的に原位に復位させる。ブレーキ片２１は内ブレーキに設けられている定位塊２３に接して定位し、平時は柱４とは接触しない。さらにブレーキ片２１の一端には定位孔２１１が設けられる。ブレーキ片２１の一端は内ブレーキ側面蓋５に設けた定位柱２４に定位され、ブレーキ片の内縁には曲面２１２が設けられて柱４に押すように作用する。
【００１７】
車輪ハブ１に設けられている内ブレーキの側端には側端蓋５が設置され、図１８から図２０に示すように、側端蓋５には少なくとも二組の組付孔５１が設けられて、ブレーキ片の定位柱２４をその中に設置し、少なくとも二個の貫通口５２が設けられて、手動ブレーキ連動板３Ａの連動塊３Ｂに貫通させてから、環状盤３の連結孔３１の中に伸び入らせて設置される。（図１の中にそれを示す。）
【００１８】
図１と図２２に示すように足で逆方向に踏んだら逆方向動力が動力入力具１１を経由して、逆方向に逆方向動力出力滑り環１１１を水平に押し動かして、内歯歯車１４の入力端の歯１４２と咬み合って連動し、内歯歯車１４の出力端の咬み合わせ部１４３と中間環６の入力端外縁の逆方向もどり止め６５を経由して逆方向動力を連動滑り環９に伝達し、連動滑り環９は中間環６の逆回転により水平に押し動かされて環状盤３の咬み合わせ部３０と咬み合って、環状盤３は旋回させられ、柱４はブレーキ片２１を押してブレーキの作用を発生する。逆方向動力が消失した時環状盤３は復位スプリング３２に弾動かされて原の位置にもどり、ブレーキの作用がなくなる。
【００１９】
さらに、内ブレーキ側端蓋５の外部に手動ブレーキ連動板３Ａを設置すれば、手動ブレーキ連動板３Ａが定位回転し、連動板３Ａの連動塊３Ｂが環状盤３を連動させて回転し、同じブレーキの作用を発生する。
【００２０】
【発明の効果】
本発明は足踏みブレーキの逆方向動力入力と手動ブレーキの二種類のブレーキ作用をもち、足踏みブレーキは逆方向動力入力経路に動力入力具１１が逆方向に水平に逆方向出力滑り環１１１を押して直接内歯歯車１４と咬み合って連動させ、さらに内歯歯車１４の出力端の咬み合わせ部と中間環６の入力端外縁の逆方向もどり止め６５の作用により、中間環６をして連動滑り環９を水平に押し動かして、環状盤３と咬み合ってそれを回転させてブレーキの作用を発止させる。それで本発明は全体の機構と動力伝達経路が極めて精密簡単にして迅速にブレーキの作用を発生する効果がある。それで二種のブレーキ操作ができる便利があり、実用的且つ安全である。

[0002]
[Prior art]
Depending on the purpose of use, conventional bicycles may be used for racing, climbing, or instead of walking, so that the design saves power and speeds up, or an external transmission (speed Or a transmission chain car with a different ratio). Since the external transmission has the entire transmission chainwheel exposed to the outside, it is constantly soiled with dust, which affects the normal operation of parts and shortens the service life. So the vendors in each country are focusing on the research and development of wheel hub internal transmission. The traditional brake is also a hub type, and is exposed on one side of the rear wheel to operate the brake by hand. So, likewise, it gets dirty and the performance gets worse. To this end, an internal transmission made in the hub has been invented.
[0003]
Therefore, between the hub internal transmission and the internal brake, the brake is interlocked by the reverse rotation of the internal transmission to produce an effect of stopping the wheels on the brake. Regarding these techniques, U.S. Pat. There are those that are released to the issue.
[0004]
There is a kind of COASTR BRAKE in those documents, but the bicycle is stopped by interlocking the brake with the reverse power output of the body transmission. Although the technology and mechanism used by each invention are different from each other due to the difference in the design philosophy, since the mechanism of the internal transmission and the internal brake is complicated and not ideal, the traders are constantly engaged in research and development.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a brake / brake transmission for a bicycle, in which the internal transmission and the internal brake can be operated by hand and can be double controlled by stepping on the foot.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the inner brake and the internal speed change mechanism of the bicycle according to the present invention are provided with an annular disc on the inner brake installed in the hub of the wheel, and a plurality of columns are provided on the annular disc. The brake pieces are rotatably mounted and a plurality of brake pieces are installed between the plurality of pillars and the fixed and immobile brake hub, and the brake pieces do not contact the brake hub and do not contact the plurality of pillars during normal times. However, when the power in the opposite direction is input from the power input device by stepping on the foot, the reverse power output slide ring is moved horizontally in the opposite direction, the circular plate is rotated, the pillar is moved, and the brake piece is moved to the brake hub. Pressing to generate brake action. Also, attach the interlocking plate of the manual brake to the outside of the side end cover of the inner brake, rotate the interlocking plate by hand operation, make the interlocking mass of the interlocking plate, and rotate the annular disk in the same way Make the action occur.
[0007]
When the interlocking plate of the manual brake according to the present invention is operated, the inner brake generates a brake action to stop the wheels, so that the bicycle is also stopped. When the foot is depressed in the opposite direction, the inner brake also acts as a brake to stop the wheels, so the bicycle is stopped. Thus, the bicycle of the present invention has a dual-use internal brake and internal transmission mechanism.
[0008]
Thereby, it has the following performance.
(1) An inner brake that has a sharp braking effect.
(2) It transmits quickly and directly transmits the internal brake and the internal shifting power.
(3) Use two types of controls that can operate the brakes separately with the feet and hands.
(4) Providing an inner brake that has the effect of stepping on the foot at the same time and the effect of braking by hand so that braking can be controlled in one or more ways, and willingly assist each other Get a safe effect.
