【考案の詳細な説明】
本考案は回転力伝達装置に係り、特にチェーン、ベルト
等を使用した回転力伝達装置において本体フレームの折
畳みを可能としたものに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotational force transmission device, and particularly to a rotational force transmission device using a chain, a belt, etc., in which the main body frame can be folded.
従来、自転車、オートバイ等は車輪中央に設けられる小
ギアに回転駆動力を伝達する場合、該小ギアと大ギアと
にチェーン、無端ベルト等を懸架せしめて行なっていた
。Conventionally, when transmitting rotational driving force to a small gear provided at the center of a wheel of a bicycle, motorcycle, etc., a chain, an endless belt, or the like is suspended between the small gear and the large gear.
しかしながら、チェーン、ベルト等は一旦懸架せられる
と、取外しが不可能であったり、たとえ取外しが可能で
あっても、次に装着が困難であるため、チェーン、ベル
トの懸架部分に相当する箇所は全く折曲が不可能であり
、従って、例えば折畳み形式の自転車、オートバイは当
該相当箇所の折曲ができず、自ずと折畳み割合が制約さ
れるものとなっていた。However, once a chain, belt, etc. is suspended, it is impossible to remove it, or even if it is possible to remove it, it is difficult to put it on again. It is completely impossible to fold the folding mechanism, and therefore, for example, foldable bicycles and motorcycles cannot be folded at the corresponding locations, and the folding ratio is naturally limited.
本考案の目的は、このようなチェーン、ベルト等を使用
した機器でもチェーン、ベルト等の懸架部分の本体フレ
ームを折畳み可能にした回転力伝達装置を提供すること
にある。An object of the present invention is to provide a rotational force transmitting device in which the body frame of the suspended portion of the chain, belt, etc. can be folded even in devices using such chains, belts, etc.
以下、本考案の一実施例を第１図及び第２図に基づいて
説明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
本体フレームは、主動側フレーム１および従動側フレー
ム２からなり、主動側フレーム１の後端部と従動側フレ
ーム２の先端部とが枢支して該枢支点３を中心に回動可
能となっており、例えば、従動側フレーム２が時計方向
に回動すると、主動側フレーム１の端部に２段に形式し
たテーパ部１ａ、ｌｂと従動側フレーム２に同じく２段
に形式したテーパ部２ａ、２ａとが相当後して主動側フ
レーム１と従動側フレーム２とが一直線となるように構
成される。The main body frame consists of a driving side frame 1 and a driven side frame 2, and the rear end of the driving side frame 1 and the tip of the driven side frame 2 are pivoted and can rotate around the pivot point 3. For example, when the driven frame 2 rotates clockwise, the tapered portions 1a and lb are formed in two stages at the end of the driving side frame 1, and the tapered portion 2a, which is also formed in two stages, is formed at the end of the driven side frame 2. , 2a, the driving side frame 1 and the driven side frame 2 are arranged in a straight line.
この主動側フレーム１の中間には、主動ギア４が、後端
側には伝動ギア５が軸支し、これらギア４．５はチェー
ン６等が懸架して連結せられる。A main drive gear 4 is pivotally supported in the middle of the main drive side frame 1, and a transmission gear 5 is pivotally supported on the rear end side, and these gears 4.5 are connected by being suspended by a chain 6 or the like.
又、前記従動側フレーム２にも同様に、中間に従動ギア
７が、先端側に受動ギア８が軸支し、チェーン９等で連
結されている。Similarly, the driven side frame 2 has a driven gear 7 in the middle, a driven gear 8 on the distal end side, and are connected by a chain 9 or the like.
そして、前記伝動ギア５と受動ギア８には、各々クラッ
チが軸支しており、該クラッチが噛合するようになって
いる。A clutch is pivotally supported by each of the transmission gear 5 and the passive gear 8, and the clutches are engaged with each other.
すなわち、伝動クラッチ１０は前記伝動ギア５と同軸で
、前記主動側フレーム１を貫通して回転自在に設けられ
、受動クラッチ１１は前記受動ギア８と同軸で前記従動
側フレーム２を貫通して回転自在に設けられ、これらは
共に、各フレーム１及び２の端部に形成した凹陥部１ｂ
及び２ｂ内に各クラッチ歯が相対向して収容、配設せら
れ、第２図のように、従動側フレーム２が回動して、各
テーパ部１ａ、１ａと２ａ、２ａとが当接して一直線の
フレームとなったとき噛合し、主動側から従動側へ回転
力を伝達するものである。That is, the transmission clutch 10 is coaxial with the transmission gear 5 and is rotatably provided through the driving frame 1, and the passive clutch 11 is coaxial with the passive gear 8 and is rotatably provided through the driven frame 2. Both of these are recessed portions 1b formed at the ends of each frame 1 and 2.
Clutch teeth are accommodated and disposed facing each other in 2b and 2b, and as shown in FIG. When the frames are in a straight line, they mesh and transmit rotational force from the driving side to the driven side.
従って、上記実施例によれば、チェーン等の取外しを要
することなく、本体フレームの折曲が可能であり、例え
ば前記主動ギア４を自転車、オートバイ等の大ギアに、
前記従動ギア７を小ギアに構成すれば、チェーン懸架部
分であっても自由に折曲が可能であり、折畳み割合を一
段と大きなものとすることが可能どなる。Therefore, according to the above embodiment, it is possible to bend the main body frame without having to remove the chain or the like.
If the driven gear 7 is configured as a small gear, even the chain-suspended portion can be bent freely, and the folding ratio can be further increased.
又、主動ギア４と従動ギア７との間には、伝動ギア５と
受動ギア８の２個の中間ギアが存在するから、主動ギア
４と従動ギア７間のギア比の変更可能範囲を大幅に拡大
できることとなる。Furthermore, since there are two intermediate gears, a transmission gear 5 and a passive gear 8, between the main gear 4 and the driven gear 7, the range in which the gear ratio between the main gear 4 and the driven gear 7 can be changed can be greatly increased. This means that it can be expanded to.
第３図および第４図は本考案の別の実施例であり、前記
主動側フレーム１の後端部が従動側フレーム２の中間に
枢支しており、従動側フレーム２が反時計方向に回動し
て伝動クラッチ１０と受道動クラッチ１Ｆとが噛合した
とき、主動側フレーム１と従動側フレーム２とが一直線
にならない場合を示したものである。FIGS. 3 and 4 show another embodiment of the present invention, in which the rear end of the driving frame 1 is pivotally supported in the middle of the driven frame 2, and the driven frame 2 is rotated counterclockwise. This figure shows a case where the driving side frame 1 and the driven side frame 2 are not in a straight line when the transmission clutch 10 and the passive driving clutch 1F are rotated and engaged.
この実施例にあっては、フレームの加工が比較的簡単で
も前述の効果を奏することができる。In this embodiment, the above-mentioned effects can be achieved even if the frame is relatively simple to process.
第５図はクラッチの別の実施例を示し、クラッチ軸先端
に鍔部１２を形威し、この鍔部１２とクラッチ１３間に
スプリング、ゴム板等の弾性体１４を介在せしめたもの
である。FIG. 5 shows another embodiment of the clutch, in which a flange 12 is formed at the tip of the clutch shaft, and an elastic body 14 such as a spring or a rubber plate is interposed between the flange 12 and the clutch 13. .
この場合には、クラッチの噛合が良好でかつ噛合時の衝
撃も吸収されて小さなものとなる。In this case, the engagement of the clutch is good and the impact at the time of engagement is absorbed and reduced.
なお、以上の各実施例の実施にあたっては、伝動クラッ
チ１０は伝動ギア５と同軸で、又受動クラッチ１１は受
動ギア８と同軸である必要はなく、第６図に示すように
、伝動ギア５と伝動クラッチ１０とをオルタム継ぎ手、
タワシ継ぎ手、自在継ぎ手等の各種継ぎ手１５と連結す
ることも可能であり、これによりクラッチの装着箇所を
適宜選択することができる。In implementing each of the above embodiments, the transmission clutch 10 does not need to be coaxial with the transmission gear 5, and the passive clutch 11 does not need to be coaxial with the passive gear 8, but as shown in FIG. and the transmission clutch 10 with an oltum coupling,
It is also possible to connect with various types of joints 15 such as scrubber joints and universal joints, so that the mounting location of the clutch can be appropriately selected.
以上、詳細に説明したように、本考案の回転力伝達装置
は、チェーン、ベルト等を懸架した箇所であっても本体
フレームを折畳むことが可能となる。As described above in detail, the rotational force transmission device of the present invention allows the main body frame to be folded even at a location where a chain, belt, etc. are suspended.
