Abstract

A problem in bicycle pedaling has been that pedaling force becomes greater when pedals are the upper and lower dead points, making traveling difficult. Using the devices of the invention reduces the amount of a body weight shift during pedaling to minimize bicycle wobbling. [MEANS FOR SOLVING PROBLEMS] When either of inner rotating gears (5L, 5R) is at the upper dead point or in its vicinity, the positions of sliding shafts (31L, 31R) of input members (pedals)(10L, 10R) provided on the inner rotating gears (5L, 5R) are shifted from each other so as not always to be positioned on a line (L) connecting each center of the inner rotating gears (5L, 5R) and a crank shaft (3). This allows the pedals (10L, 10R) to be reciprocatively moved in the vertical direction, causing the inner rotating gears (5L, 5R) to be rolled while being meshed with stationary gears (6L, 6R), the meshing being effected by leverage on the fulcrums that are the contact points between each internal rotating gear (3L, 3R) and the mating stationary gear (6L, 6R). As a result, reciprocating motion in the vertical direction of the pedals are converted to rotational drive motion of the crank shaft (3), so that rotational force is taken out to the outside from rotational force take-out means (sprocket)(7).

However, when the pedal is depressed to apply rotational motion to the crankshaft, the weight shifts and the pedal is depressed, causing the steering wheel to fluctuate, causing unstable running and transmission of power to the crank device. Efficiency was lost. As a technique devised to solve such a problem, for example, a technique disclosed in Japanese Utility Model Publication No. 2-444628 is known. The bicycle pedal crank device described in this publication also includes a pair of upper and lower sprockets provided on the left and right sides of a sprocket mounted on a sprocket fixed to a crankshaft. Wrap a pair of chains between the sprockets, attach the left and right pedals so that they can be disengaged from the tight side of the chain, and repeat the operation of stepping on the pedals from top to bottom to the wheels. It transmits the driving force so that the vehicle can run.
ところが、 上記のペダルクランク装置を備えた自転車であっても、 ぺダ ルの取り付け位置と、 スプロケッ卜の回転軸心との間に存する距離が、 梃 子の腕として機能するため、 ペダルの踏み込み力によるモーメン卜が作用 し、 結果として体重移動による自転車のふらつき現象が生じてしまい、 依 然としてハンドルがふらつき、 不安定な走行をするようになると共に、 ク ランク装置の動力伝達効率を損ねるという問題が解消されなかった。 そこ で、 このような問題点を解決するために、 内転歯車が上死点近傍にある場 合には、内転歯車に設けられる入力部材（ペダル）の取り付け軸の位置を、 入力時に内転歯車と、 クランク軸との各中心を結ぷ線上に存在しないよう にオフセット配置するように形成することで、 クランク軸を円滑に回転駆 動して回転力を取り出し手段 （例えば、 スプロケットやべベル軸） から外 部に取り出すようにしたクランク装置と、 それを備えた乗り物用べダルク ランク装置を提供しょうとするのが、 本発明の目的 （課題） である。 発明の開示  However, even with a bicycle equipped with the pedal crank device described above, the distance between the pedal mounting position and the axis of rotation of the sprocket functions as a lever arm, so the pedal must be depressed. Moment due to force acts, causing the bicycle to wobble due to weight shift, resulting in the wobbling of the steering wheel, leading to unstable running and impairing the power transmission efficiency of the crank device. The problem did not go away. Therefore, in order to solve such a problem, when the adduction gear is near the top dead center, the position of the mounting shaft of the input member (pedal) provided on the adduction gear is set to By forming the center of the rolling gear and the center of the crankshaft so as to be offset so that they do not exist on the connection line, the crankshaft is smoothly driven to rotate to extract the rotational force (for example, a sprocket or a It is an object (problem) of the present invention to provide a crank device that is taken out from a bell shaft) and a vehicle-mounted pedal crank device provided with the crank device. Disclosure of the invention
上記課題を解決するために、本発明においては次のような手段を講ずる こととした。 すなわち、 請求項 1記載の発明においては、 固定部材に軸受 け部を介して回転自在に設けられたクランク軸、 このクランク軸両側に設 けられた一対のクランク腕、 上記各クランク腕に回転自在に設けた一対の 内転歯車、 上記固定部材に設けられ、 上記各内転歯車を遊星歯車的に内接 させて嚙合する固定歯車、上記各内転歯車に設けられた一対の駆動力伝達 手段、 各駆動力伝達手段に係合された一対の入力部材、 および上記クラン ク軸に一体的に設けられ、 上記各内転歯車から上記各クランク腕に伝達さ れた回転力を推進力として取リ出す回転力取リ出し手段を具備すると共 に、 上記内転歯車と上記固定歯車との歯数比を、 上記内転歯車が上記固定 歯車を転動しながら 1周するときに 1回転するように形成し、 さらに、 上 記入力部材を介して上記駆動力伝達手段に駆動力を作用させたとき （入力 時） に、 上記内転歯車と上記固定歯車とが嚙合する接点を支点として、 上 記内転歯車に回転モーメントが生じ、上記回転力取り出し手段を駆動させ る構成を採用した。 In order to solve the above problems, the present invention has taken the following measures. That is, in the invention according to claim 1, a crankshaft rotatably provided on a fixed member via a bearing portion, a pair of crank arms provided on both sides of the crankshaft, and a rotatable rotation on each of the crank arms A pair of internal gears provided on the fixed member, a fixed gear provided on the fixing member, and in which the internal gears are inscribed in a planetary gear manner, and a pair of driving force transmitting means provided on the internal gears. A pair of input members engaged with each driving force transmitting means; And a rotational force take-out means provided integrally with the shaft to take out the rotational force transmitted from each of the add-on gears to each of the crank arms as a propulsion force. The ratio of the number of teeth to the fixed gear is formed such that the internal gear rotates once when the internal gear makes one revolution while rolling on the fixed gear, and further, the driving force transmitting means via the input member. When a driving force is applied to the internal gear (at the time of input), a rotational moment is generated in the internal gear with the contact point between the internal gear and the fixed gear as a fulcrum, and the rotational force extraction means is driven. Configuration was adopted.
請求項 1記載の発明では、軸受け部に回転自在に設けたクランク軸両側 の一対のクランク腕に内転歯車を設け、 この内転歯車を固定歯車に内接さ せながら嚙合して転動するように形成する。 そして、 内転歯車が固定歯車 を 1周する間に 1回転するような歯数比に設定し、 さらに内転歯車に設け た駆動力伝達手段に入力部材を係合するようにしているので、 入力部材を 上死点近傍から下死点近傍に向かって押し下げると、 内転歯車と固定歯車 との接点を支点とする梃子の作用により、 内転歯車に回転モーメントが生 じる。 これにより、 内転歯車が固定歯車に転動すると同時にクランク腕を 介してクランク軸が回転運動をし、 これにより回転力取り出し手段から回 転駆動力を外部に取り出すことができる。 このため、 左右一対の入力部材 を、 左右交互にこぐ (押し下げ運動) とき、 振れの少ない態様で上下方向 に往復運動を行わせることができ、 この結果、 往復運動による作動力を、 効率よく回転運動力に変換できるようになる。  According to the first aspect of the present invention, an internal gear is provided on a pair of crank arms on both sides of the crankshaft rotatably provided on the bearing portion, and the internal gear is joined and rolled while being inscribed in the fixed gear. It is formed as follows. Then, the gear ratio is set so that the adduction gear makes one revolution while making one rotation of the fixed gear, and the input member is engaged with the driving force transmission means provided on the adduction gear. When the input member is pushed down from the vicinity of the top dead center to the vicinity of the bottom dead center, a rotating moment is generated in the adduction gear by the action of a lever having a contact point between the adduction gear and the fixed gear as a fulcrum. As a result, the internal gear rotates to the fixed gear, and at the same time, the crankshaft rotates via the crank arm, whereby the rotational driving force can be extracted to the outside from the rotational force extracting means. For this reason, when the pair of left and right input members are alternately slid left and right (push-down motion), reciprocating motion can be performed in a vertical direction in a manner with little vibration, and as a result, the operating force due to the reciprocating motion can be efficiently rotated. You will be able to convert to exercise.
また、 回転力取り出し手段を、 例えばチェーンやベルトといった巻き掛 けリンク機構でなく、 ベベルギヤとドライブシャフトでなるシャフ卜駆動 システムで形成した場合には、巻き掛けリンク機構の遊びやたるみが発生 しないので、 ペダルに加えられた回転力をロスすることなく車輪に伝達す ることができ、 ェネルギ伝達効率を向上できるようになる。 また、 クランク軸の両側に設けられるクランク腕は、 互いにクランク軸 に対して反対方向に伸びるような腕に形成されるが、 この代わりに位相角 度のない状態、 すなわち互いに同じ方向に伸びるような腕に形成してもよ く、要するにクランク軸から伸びる方向は任意に設定した形態に形成して よいものであるのは言うまでもない。 Also, if the rotational force take-out means is formed by a shaft drive system consisting of a bevel gear and a drive shaft, instead of a winding link mechanism such as a chain or belt, play and slack of the winding link mechanism will not occur. However, the torque applied to the pedal can be transmitted to the wheels without loss, and the energy transmission efficiency can be improved. Also, the crank arms provided on both sides of the crankshaft are formed as arms that extend in opposite directions to each other with respect to the crankshaft, but instead have no phase angle, that is, extend in the same direction as each other. Needless to say, the arm may be formed on the arm, that is, the direction extending from the crankshaft may be arbitrarily set.

軌道誘導部の具体的な構造を、 例えば、 左側の軌道誘導部 3 2 Lを例に 挙げて説明する。 図 4 , 図 5において、 楕円形状の案内溝 3 4 Lが形成さ れた第 1部材 3 3しと、 この第 1部材 3 3 Lにビス 3 4 Lを介して蓋をす るようにして設けられた第 2部材 3 5 Lとを有しており、 これらの第 1部 材 3 3 Lと第 2部材 3 5 Lとで内部に案内溝 3 4 Lが形成されることと なる。 左側の軌道誘導部 3 2 Rも同様にして形成される。  The specific structure of the trajectory guiding section will be described using, for example, the trajectory guiding section 32L on the left side as an example. In FIGS. 4 and 5, a first member 33 having an elliptical guide groove 34 L formed thereon, and a lid is attached to the first member 33 L via a screw 34 L. The first member 33L and the second member 35L have a guide groove 34L formed therein. The left track guiding section 32R is formed in the same manner.
入力部材たるペダル 1 0 Lは、 取り付け軸 1 1 し、 すなわちペダル軸 1 1 しに対して回転自在に設けられ、 ペダル 1 1 L端部には、 ピン状の摺動 子 3 1 Lが設けられ、 案内溝 3 4 Lに係合する。 摺動子 3 1 Lは、 内転歯 車 5 Lの案内溝 3 4 Lにはまりこんでいるとき、 終始、 案内溝 3 4 Lの最 下方の位置に存置するようになり、 これにより、 上死点またはその付近に あるペダル 1 1 Lを踏み込んでこぐ場合の入力点として機能することと なる。また、摺動子 3 1 L力 このよう入力点に位置する場合においては、 図 3に示す内転歯車 5 Lの軸心 P 1と、 クランク軸 3の軸心 P 2とを結ぶ 線し （クランク 3を通る上下方向の中心線） から偏倚した位置にオフセッ 卜されている。 なお、 このオフセット方向は、 図 3において線 Lの右方、 すなわち、 自転車の進行する方向に対して後方向にオフセッ卜されている。 したがって、 図 3に示す状態にあるペダル軸 1 1 Lに対して、 上から下 に向かって足の踏み込み力 （作動力） が作用した場合には、 内転歯車 5 L と固定歯車 6 Lとの嚙合部、 すなわち、 接点が梃子の支点となり、 この接 点と摺動子 3 1 Lとの距離が梃子の長さとなり、梃子の作用により内転歯 車 5 Lに時計方向の回転 （自転） を与えると同時に、 内転歯車 5 Lは、 固 定歯車 6しに嚙合しながら矢印 X方向 （反時計方向） に転動していくこと となる。 The pedal 10 L, which is an input member, is provided rotatably with respect to the mounting shaft 11, that is, the pedal shaft 11, and a pin-shaped slider 31 L is provided at the end of the pedal 11 L. And engage the guide groove 34L. When the slider 31 L is stuck in the guide groove 34 L of the adduction gear 5 L, the slider 31 L is always located at the lowermost position of the guide groove 34 L. At or near the point It will function as an input point when depressing and pedaling on a certain pedal 11L. In addition, when the slider 3 1 L force is located at such an input point, a line connecting the axis P 1 of the internal gear 5 L and the axis P 2 of the crankshaft 3 shown in FIG. Offset from the vertical center line passing through the crank 3). Note that this offset direction is offset to the right of the line L in FIG. 3, that is, in the backward direction with respect to the traveling direction of the bicycle. Therefore, when the stepping force (operating force) of the foot acts on the pedal shaft 11 L in the state shown in FIG. 3 from top to bottom, the adduction gear 5 L and the fixed gear 6 L Where the contact point becomes the fulcrum of the lever, the distance between this contact point and the slider 31L becomes the length of the lever, and the lever acts to rotate the adduction gear 5L clockwise (rotation). ), The adduction gear 5 L rolls in the arrow X direction (counterclockwise) while engaging with the fixed gear 6.
また、 このような機構にすることにより、 ペダルを踏み込んで下方に移 動していくときのペダルの速度は、歯車が嚙合する上記接点から摺動子 3 In addition, by adopting such a mechanism, the speed of the pedal when the pedal is depressed and moves downward is controlled by the slider 3 from the contact point where the gear is engaged.
1 Lまでの長さ （梃子の腕の長さ） の変化に応じた大きさとなるものであ る。 The size depends on the change in length (length of lever arm) up to 1 L.
他方、 右側のペダル 1 0 Rのペダル軸 1 1 Rも、 左側のペダル 1 0しと 同じようにして、 内転歯車 5 Rに軌道誘導部 3 2 Lと同じ構造を有する軌 道誘導部 3 2 Rの案内溝 （図示しない） を介して係合される。  On the other hand, in the same manner as the left pedal 10 R, the pedal shaft 11 R of the right pedal 10 R also has the orbital gear 5 R on the orbit guide 3 with the same structure as the track guide 3 2 L. Engaged via 2R guide groove (not shown).
また、 ベースプレート 1 aと右側の固定歯車 6 Lとの間のクランク 3に は、 回転力を取り出すための原動スプロケット 7がクランク軸 3と一体回 転可能になるように設けられ、 チェーン 9 (図 1参照） を巻き掛けして車 輪側の従動スプロケット （図 1の符号 8 ) に結合されることとなる。  In addition, a driving sprocket 7 for taking out a rotational force is provided on the crank 3 between the base plate 1 a and the right fixed gear 6 L so as to be able to rotate integrally with the crank shaft 3, and a chain 9 (see FIG. 1) and is connected to the driven sprocket on the wheel side (reference numeral 8 in Fig. 1).
こうして、 クランク装置は、 図 6の組み立て分解斜視図に示すようにし て上記した各構成要素を順次組み立てていくことにより図 2のように製 作される。 なお、 図 6において、 符号 2 3は軸部材 5 L 1 , 5 R 1の軸端 に圧入されて各内転歯車 5し、 5 Rを軸部材 5 L 1 , 5 R 1に取り付ける ためのプッシュナツトを示すと共に、原動スプロケットフの図示は省略し ている。 In this way, the crank device is manufactured as shown in FIG. 2 by sequentially assembling the above-described components as shown in the exploded perspective view of FIG.

In FIG. 6, reference numeral 23 denotes a push for press-fitting the shaft ends of the shaft members 5 L 1 and 5 R 1 to form the internal gears 5, and attaching 5 R to the shaft members 5 L 1 and 5 R 1. The nuts are shown, and the driving sprocket is not shown.
次に、 本実施の形態のクランク装置を備えた自転車のペダルクランク装 置の作用を、 図 7、 図 8、 図 9を参照して説明する。 図 7は、 ペダル軸 1 1 L、 1 1 Rの軸端に設けた摺動子 3 1 L、 3 1 Rが、 左右各内転歯車 5 L、 5 Rに設けた各案内溝 3 4 Lを、 上死点近傍から下死点過ぎまでの間 における移動軌跡を画いた作用説明図である。 実線は、 左側の内転歯車 5 Lの移動軌跡を示し、 点線は反対側にあるお側の内転歯車 5 Rの摺動子 3 1 Rの移動軌跡をそれぞれ示している。  Next, the operation of the pedal crank device of the bicycle provided with the crank device of the present embodiment will be described with reference to FIGS. 7, 8, and 9. FIG. Fig. 7 shows the sliders 31L and 31R provided at the shaft ends of the pedal shafts 11L and 11R, respectively, and the guide grooves 34L provided in the left and right internal rotation gears 5L and 5R. FIG. 9 is an operation explanatory diagram illustrating a movement trajectory from near the top dead center to just after the bottom dead center. The solid line shows the movement trajectory of the left inner gear 5L, and the dotted line shows the movement trajectory of the slider 31R of the opposite inner gear 5R.
自転車のペダル 1 0し、 1 O Rのうち、 図 8に示すように、 例えば、 上 死点またはその付近にある左側のペダル 1 0 Lからこぎ出す場合におい て、 内転歯車 5 Lには、 ペダル 1 1 Lの摺動子 3 1 しから案内溝 3 4 Lを 介して、梃子の作用により時計方向に回転（自転）する回転力が作用する。 すると、 内転歯車 5 Lは、 固定歯車 6 Lに嚙合しながら矢印 C方向に転動 (公転） していく。 内転歯車 5 L力 下死点またはその近傍に転動してく ると、 摺動子 3 1 Lと案内溝 3 4 Lとの相対位置関係は、 図 9に示す状態 となる。 内転歯車 5 Lが下死点またはその近傍までくると、 今度は反対側 にある右側の内転歯車 5 Rが上死点またはその近傍に移動し上昇してく る。 左側のペダル 1 0 Lをこいだ場合と同様にして右側のペダル 1 O Rを こぐと、 それに作用する踏み込み力は、 ペダル軸 1 1 Rの摺動子 3 1 Rか ら駆動力伝達手段 3 0 Rの案内溝を介して内転歯車 5 Rに伝達される。 こうして、 図 7に示すように、 各内転歯車 5 L、 5 Rが固定歯車 6し、 6 Rに対してどのような転動位置にあっても、 常に各摺動子 3 1 L、 3 1 Rは、 案内溝 3 4し、 3 4 Rに対して最下方の位置に存置されるように位 置するので、 上下方向に往復運動する左おのペダル 1 0し、 1 O Rを交互 に踏み込んでこいでいくことで、 各内転歯車 5し、 5 Rが梃子の作用によ リ各固定歯車 6 L、 6 Rを嚙合しながら転動していき、 出力軸たるクラン ク軸 3が回転運動し、 その回転駆動力を原動スプロケットフからチェーン 9を介して従動スプロケッ卜 8に伝達され、車輪を駆動して推進力を生じ て前進走行することができるようになる。 As shown in Fig. 8, of the bicycle pedals 10 and 1 OR, for example, when starting from the left pedal 10 L at or near the top dead center, the adduction gear 5 L Through the guide groove 34 L from the slider 31 of the pedal 11 L, a rotating force that rotates clockwise (self-rotation) acts by leverage. Then, the adduction gear 5 L rolls (revolves) in the direction of arrow C while engaging with the fixed gear 6 L. Internal Roller Gear 5 L Force Rolling at or near the bottom dead center, the relative positional relationship between the slider 31 L and the guide groove 34 L is as shown in FIG. When the adduction gear 5L reaches the bottom dead center or its vicinity, the right adder gear 5R on the opposite side moves to the top dead center or its vicinity and rises. When the right pedal 1OR is squeezed in the same way as when the left pedal 10L is squeezed, the depressing force acting on the right pedal 1OR is transmitted from the slider 31R of the pedal shaft 11R to the driving force transmitting means 30 It is transmitted to the adduction gear 5R via the R guide groove. Thus, as shown in FIG. 7, each of the internal gears 5 L and 5 R is a fixed gear 6, and regardless of the rolling position with respect to 6 R, each of the sliders 3 1 L and 3 R 1 R is positioned so that it is located at the lowest position with respect to guide groove 3 4 R and 3 4 R. The left and right pedals reciprocating up and down 10 0 and 1 OR are alternately depressed and come in.Each addendum gear 5 and 5 R are each fixed gear by lever action. Rolling while combining 6 L and 6 R, the crank shaft 3, which is the output shaft, rotates, and its rotational driving force is transmitted from the driving sprocket to the driven sprocket 8 via the chain 9, By driving the vehicle, a propulsion force is generated and the vehicle can run forward.
上記したごとく、 本実施の形態によれば、 自転車のペダルをこぐとき、 ペダル 1 O L、 1 0 Rの取り付け軸であるペダル軸 1 1 L、 1 1 Rの摺動 子 3 1 L、 3 1 Rの移動軌跡は、図 7に示されるように、各内転歯車 5 L、 5 Rが上死点またはその近傍に転動してきたときに、 思案点 （死点〉 とな らない位置に、各摺動子 3 1 L、 3 1 Rが存在し、かつ、各褶動子 3 1 L、 3 1 Rは、 略上下方向に沿った軌跡上を往復運動するようになっている。 このため、従来のようにペダルをこぐときべダルに体重を移動してこいで いたために生じていた自転車のふらつきは、体重移動を少なくできるため、 ふらつきの発生を抑制することができるようになり、 その結果、 ペダル 1 0し、 1 0 Rを上下に往復運動させるだけで原動スプロケット 7に円滑、 且つ、 安定して回転運動を伝達することができ、 自転車の駆動力ロスを有 効に低減することができるようになる。  As described above, according to the present embodiment, when pedaling the bicycle, when sliding the pedals 1 OL and 10 R, the sliders 3 1 L and 3 1 of the pedal shafts 11 L and 11 R are attached. As shown in FIG. 7, the movement trajectory of R is at a position that does not become a conceivable point (dead point) when each of the internal gears 5L and 5R rolls at or near the top dead center. The sliders 31L and 31R are present, and the sliders 31L and 31R reciprocate on a locus substantially along the vertical direction. As a result, the wobbling of the bicycle, which had been caused by shifting the weight to the pedal when pedaling as in the past, can be reduced, and the occurrence of wobbling can be suppressed. As a result, the pedals 10 and 10 R can be smoothly and stably rotated on the driving sprocket 7 simply by reciprocating up and down. It can be transmitted dynamic, so that it is possible to reduce the driving force loss of the bicycle enabled.
以上、 本発明の実施の形態を図面により詳述してきたが、 具体的な構成 はこの実施の形態に限られるものでなく、本発明の要旨を逸脱しない範囲 の設計変更等があっても本発明の範囲に含まれるものである。  Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. It is within the scope of the invention.
すなわち、 上記実施の形態に係るクランク装置は、 自転車に適用した場 合について説明したが、 自転車の他に、 3輪自転車、 4輪自転車、 水上を ペダルクランク装置で踏み込んでこぐポー卜や、 トレーニング機器用具や 人力飛行機といった各種乗り物に用いた乗り物用クランクペダル装置、 さ らにはこれらクランク装置や乗り物用クランクペダル装置を備え、 ペダル 等を下方向へ踏み込み、前方法へ踏み出すようにした乗り物にも適宜に応 用できるものであることは勿論である。 That is, the crank device according to the above-described embodiment has been described as applied to a bicycle. In addition to a bicycle, a three-wheeled bicycle, a four-wheeled bicycle, a port for pedaling on water with a pedal crank device, and training. Vehicle crank pedal devices used for various vehicles such as equipment and human-powered airplanes, and equipped with these crank devices and vehicle crank pedal devices, It is needless to say that the present invention can be appropriately applied to a vehicle in which the user steps down in the downward direction and steps forward.
また、 上記実施形態に係るクランク装置では、 図 2、 図 6に示される構 成要素 （部品） で形成し、 これら部品を組み立てて構成したが、 実施に際 しては、 これら以外の構成要素 （部品） で構成して組み立てる態様にでき ることは言うまでもない。  Further, in the crank device according to the above-described embodiment, the components (parts) shown in FIGS. 2 and 6 are formed and assembled by assembling these components. Needless to say, it can be configured to be composed of (parts).
また、 本実施の形態では、 案内溝 3 4 L、 3 4 Rに摺動子 3 1 L、 3 1 Rを嵌め込んだ構成とした場合について説明したが、 この代わりに図 1 0 に示すように、 軌道誘導部 3 2し、 3 2 Rに、 楕円形状の案内レール 4 0 を取り付け、 この案内レール 4 0にスライドするスライダ 4 1を係合させ ることもできる。 なお、 この場合には、 スライダ 4 1はペダル軸 1 1 し、 1 1 Rを回転自在に取り付けるようにする。 これによつて、 スライダ 4 1 は案内レール 4 0の最下方近傍で存置する状態で滑動し、 内転歯車 5 L、 5 Rを転動させることができる。  Further, in the present embodiment, a description has been given of a case where the sliders 31 L, 31 R are fitted into the guide grooves 34 L, 34 R, but instead, as shown in FIG. Then, an elliptical guide rail 40 may be attached to the orbit guides 32 and 32R, and the slider 41 sliding on the guide rail 40 may be engaged. In this case, the slider 41 is made to correspond to the pedal shaft 11 and the 11R is rotatably mounted. Thus, the slider 41 slides while remaining near the lowermost portion of the guide rail 40, and can rotate the internal gears 5L and 5R.
また、 上記では、 軌道誘導部 3 2 L、 3 2 Rを、 楕円形状の案内溝 3 4 しゃ、 案内レール 4 0により形成したが、 この代わりに、 略直線状や湾曲 した曲線形状を呈した 1本のレールの形態で構成したものであってもよ い。  Further, in the above description, the orbital guiding portions 32L and 32R are formed by the elliptical guide grooves 34 and the guide rails 40. Instead, they have a substantially linear shape or a curved shape. It may be configured in the form of one rail.
また、 図 1 1に示すように、 略直線状の傾斜溝 5 0を有する案内溝に形 成し、 この傾斜溝 5 0を備えた軌道誘導部 5 1を内転歯車 5に取り付ける ようにした態様であってもよい。 この場合において、 傾斜溝 5 0内にスプ リング 5 2を収縮した状態で収納し、 入力時摺動子 3 1 L、 3 1 Rを最下 方近傍に存置するようにばね力を作用させるようにしておく。 これによつ て、 摺動子 3 1 L、 3 1 Rが、 内転歯車 5の転動位置に関係なく、 常に内 転歯車 5の軸心 P 1と、 クランク軸 3の軸心 P 2とを結ぶ線 L (クランク 軸 3を通る上下方向の中心線） から偏倚した位置にオフセットしておくこ とができる （図 3参照）。 Further, as shown in FIG. 11, a guide groove having a substantially linear inclined groove 50 is formed, and the track guiding portion 51 having the inclined groove 50 is attached to the adduction gear 5. It may be an aspect. In this case, the spring 52 is housed in the inclined groove 50 in a contracted state, and a spring force is applied so that the sliders 31 L and 31 R at the time of input are located near the bottom. Keep it. As a result, the sliders 31L and 31R always keep the axis P1 of the internal gear 5 and the axis P2 of the crankshaft 3 regardless of the rolling position of the internal gear 5. Offset from the line L (the vertical centerline passing through the crankshaft 3) (See Figure 3).
また、 軌道誘導部に形成される案内溝を、 図 1 1に示される上記変形例 のように略直線状の形状に形成するのではなく、 湾曲を画くような曲線状 に形成するようにしてもよい。  Also, the guide groove formed in the track guiding portion is not formed in a substantially linear shape as in the above-described modified example shown in FIG. 11, but is formed in a curved shape so as to draw a curve. Is also good.
また、 図 1 1に示すように、 傾斜溝 5 0にばね部材としてのスプリング As shown in FIG. 11, the inclined groove 50 has a spring as a spring member.
5 2を設けたが、 スプリング 5 2を設けない態様にしてもよいものである。 したがって、 このような構成とすることで、 図 1 2〜図 1 4において示 したように、 摺動子 3 1 L、 3 1 Rは、 軌道誘導手段 5 1の傾斜溝 5 0の 最下方近傍に存置されながら、 内転歯車 5が固定歯車 6に嚙合して転動し ていく。 このとき、 内転歯車 5は、 固定歯車 6を反時計方向に転動 （公転） していくと共に、 自身は時計方向に自転していくこととなり、 摺動子 3 1 L、 3 1 Rは図 1 2〜図 1 4に示すような移動軌跡を画いて上死点から下 死点に移動していく。 その結果、 係る変形例においても、 上記実施の形態 と同様に、 ふらつきの少ない駆動力伝達を行うことができる効果を有する。 また、 図 1 5に示す変形例のように、 例えば、 内転歯車 5 Lと固定歯車Although 52 is provided, the spring 52 may not be provided. Therefore, by adopting such a configuration, as shown in FIGS. 12 to 14, the sliders 31 L and 31 R are located near the lowermost portion of the inclined groove 50 of the track guiding means 51. The internal gear 5 rolls together with the fixed gear 6 while remaining in the fixed position. At this time, the internal gear 5 rotates (revolves) the fixed gear 6 in the counterclockwise direction, and also rotates itself in the clockwise direction, so that the sliders 3 1 L and 3 1 R The robot moves from the top dead center to the bottom dead center by drawing a movement trajectory as shown in Figs. As a result, even in such a modified example, as in the above-described embodiment, there is an effect that the driving force can be transmitted with less fluctuation. In addition, as shown in a modified example shown in FIG. 15, for example, an adduction gear 5 L and a fixed gear
6 Lとの嚙合状態が外部から見えないようにするため、 二点鎖線で示すご とく内転歯車 5 Lと固定歯車 6しとを覆うカバ一 7 0をとりつけるよう に形成することもできる。 この場合、 カバー 7 0は固定歯車 6 L側に取り 付けるが、 結果として 2つの歯車 5 L , 6 Lの嚙合部に外部から小石や衣 服が嚙み込むことがないように設けるのであれば、 カバー 7 0は自転車等 の車体本体に取り付けるように形成してもよい。 したがって、 この変形例 によれば、 両歯車 5 L , 6 Lの嚙合部に衣服や飛び石等が嚙み込んだりし てケガするのを確実に阻止することができるようになる。 In order to prevent the combined state with 6 L from being seen from the outside, it is also possible to form a cover 70 covering the internal gear 5 L and the fixed gear 6 as shown by the two-dot chain line. In this case, the cover 70 is attached to the fixed gear 6L side, but as a result, if it is provided so that pebbles and clothes do not enter the joint of the two gears 5L and 6L from the outside. The cover 70 may be formed so as to be attached to a vehicle body such as a bicycle. Therefore, according to this modified example, it is possible to surely prevent injuries caused by clothes, stepping stones or the like entering the joint between the two gears 5L and 6L.
また、 この場合において、 上記カバー 7 0の代わりに、 図 1 5 ( b ) の 二点鎖線に示すように、 内転歯車 5 Lの外側に、 この内転歯車 5 Lの外径 よりも若干大きめの内盤状のカバー 7 0 1を一体に同心円的な配置関係 で取り付けるようにすることもでき、 これにより図 1 5 ( a ) の場合と同 様に、 内転歯車 5 Lと固定歯車 6 Lとの嚙み合いを長く良好な状態に保持 することができるようになる。 In this case, instead of the cover 70, as shown by a two-dot chain line in FIG. 15 (b), the outside diameter of the internal gear 5L is slightly smaller than the outer diameter of the internal gear 5L. Large inner cover 70 1 concentrically arranged As a result, the engagement between the internal gear 5 L and the fixed gear 6 L can be maintained in a long and favorable state, as in the case of Fig. 15 (a). Become like
また、 別の変形例として、 図 1 5において、 固定歯車 6に、 上下方向に 沿って配置した 2本の棒部材でなるガイ ド 7 1を取り付け、 このガイ ド 7 1に入力部材であるペダルの取り付け軸 （ペダル軸） 1 1 Lが上下方向の 往復運動を規定されるようにすることもできる。 この変形例によれば、 急 ブレーキ等によるペダルの大きな移動 （変位） を避けることで、 ペダルか らの足の離脱するのを防ぐことができ、 自転車転倒時にペダル軸 1 1 しが 受ける衝撃力により、 固定歯車 6 Lや内転歯車 5 Lの歯が切損したりして 嚙み合わせに不具合を生じるといった事態を未然に回避することができ るようになる。 もちろん、 このガイド 7 1単体を設ける代わりに、 上記力 バー 7 0自体にガイ ド機能を有するスリッ 卜を往復運動方向に指向して 設け、 これによりペダル軸 1 1 Lを上下方向に案内するようにしてもよし、。 また、 上記実施の形態では、 回転力取り出し手段として原動スプロケッ 卜フと従動スプロケッ 卜 8との間にチェーン 9を巻き掛けしてなる巻き 掛けリンク機構で形成した場合について説明したが、 例えば、 クランク装 置を模式的に表した図 1 6に示すように、 シャフトドライブシステムで動 力を伝達する構造にすることも可能である。 すなわち、 原動スプロケット 7の代わりにクランク軸 3にべベル歯車 8 1 を一体回転可能に取り付け、 従動側の車輪スプロケット 8の代わりにべベル歯車 8 2を設け、 チェーン 9の代わりに両端にベベル歯車 8 3 , 8 4を有するドライブ軸 8 5を設け た構造にしたものである。 これにより、 クランク腕 4からクランク軸 3に 伝達した駆動力が、 ベベル歯車 8 1からドライブ軸 8 5のべベル歯車 8 3 に伝わるとき、 ベベル歯車 8 2にドライブ軸 8 5のべベル歯車 8 4がにそ れぞれ嚙合する構成にしたため、 チ: I：ーン 9のように弛みを生じることが なく、 ペダル 1 0を踏み込んでこぐ力は、 効率的に回転運動に変換して従 動側に伝達することができる効果を有する。 Further, as another modified example, in FIG. 15, a guide 71 composed of two rod members arranged along the vertical direction is attached to the fixed gear 6, and a pedal as an input member is attached to the guide 71. The mounting shaft (pedal shaft) of 1L can be defined so that the vertical reciprocation is defined. According to this modification, it is possible to prevent the pedal from detaching from the pedal by avoiding large movement (displacement) of the pedal due to sudden braking or the like, and the impact force applied to the pedal shaft 11 when the bicycle falls down Accordingly, it is possible to prevent a situation in which the teeth of the fixed gear 6 L and the adduction gear 5 L are cut off or a malfunction occurs in the engagement. Of course, instead of providing the guide 71 alone, a slit having a guide function is provided in the force bar 70 itself so as to be oriented in the reciprocating direction, thereby guiding the pedal shaft 11 L in the vertical direction. Anyway, Further, in the above-described embodiment, a case has been described in which the rotational force extracting means is formed by a winding link mechanism in which a chain 9 is wound between a driving sprocket and a driven sprocket 8. As shown in Fig. 16 schematically showing the device, it is possible to adopt a structure in which power is transmitted by a shaft drive system. That is, instead of the driving sprocket 7, a bevel gear 8 1 is attached to the crankshaft 3 so as to be able to rotate integrally, a bevel gear 8 2 is provided in place of the driven wheel sprocket 8, and bevel gears are provided at both ends instead of the chain 9. This is a structure in which a drive shaft 85 having 83 and 84 is provided. As a result, when the driving force transmitted from the crank arm 4 to the crankshaft 3 is transmitted from the bevel gear 8 1 to the bevel gear 8 3 of the drive shaft 85, the bevel gear 82 becomes the bevel gear 8 of the drive shaft 85. 4 is configured so that it can be loosened as shown in Fig. 9 However, there is an effect that the force depressed on the pedal 10 can be efficiently converted into rotational motion and transmitted to the driven side.
また、 上記実施の形態では、 固定歯車として平歯を刻んで形成した固定 歯車 6 L , 6 Rを使用した場合について説明した力 この代わりに図 1 7、 図 1 8に示すような固定歯車 6 0と、 内転歯車 5との組み合わせによる嚙 み合い装置の態様とすることも可能である。 なお、 この嚙み合い装置は、 上記実施の形態と同様に、 自転車等の乗り物フレームに対して左右にそれ ぞれ設けられるが、 以下では便宜上、 いずれか一方側にある嚙み合い装置 を代表して説明していくこととする。  Further, in the above embodiment, the force described in the case where the fixed gears 6 L and 6 R formed by cutting the spur teeth are used as the fixed gears. Instead, the fixed gears 6 shown in FIGS. 17 and 18 are used instead. It is also possible to adopt a mode of a meshing device by a combination of 0 and the adduction gear 5. The engaging devices are provided on the left and right sides of a vehicle frame such as a bicycle in the same manner as in the above-described embodiment. However, for convenience, the engaging devices on either one side are represented below for convenience. It will be explained.
すなわち、 固定歯車 6 0は、 図 1 フ （a ) に示すように、 一対のリング 板状基部 6 0 aの間に、複数のピン部材 6 0 bを配置して設け、あるいは、 図 1 7 ( b ) に示す固定歯車 6 1のように、 一個のリング板状基部 6 1 a から片持ち梁状に突出させたピン部材 6 1 bを配置して設けた、実質的に チェーン機能を有する形態に形成する。 この場合、 これらピン部材 6 O b をリング状基板部 6 0 aに対して相対回転する口一ラー状のピンとし、機 械的摩擦を低減するようにしてもよい。 そして、 これら固定歯車 6 0ある いは固定歯車 6 1の内側に嚙み合って回る内転歯車 5を、 図 1 8に示すよ うに、 スプロケットの形態に形成することもできる。 これにより、 チェ一 ン形態とスプロケッ卜形態との嚙み合いによリ嚙み合い装置が構成され ることとなり、 上記実施の形態と同様にペダルの踏み込み力を円滑に伝達 することが可能となる。 なお、 この場合、 固定歯車 6 0に直接、 チェ一ン を取リ付けるようにしてもよいことは言うまでもない。  That is, the fixed gear 60 is provided with a plurality of pin members 60b arranged between a pair of ring plate bases 60a as shown in FIG. Like a fixed gear 61 shown in (b), a pin member 61b protruding from one ring plate-like base 61a in a cantilever shape is provided and has a substantially chain function. Form into a form. In this case, these pin members 6 O b may be formed as pin-shaped pins that rotate relative to the ring-shaped substrate section 60 a to reduce mechanical friction. Further, the adduction gear 5 that rotates while meshing with the inside of the fixed gear 60 or the fixed gear 61 can be formed in the form of a sprocket as shown in FIG. As a result, the engagement device is constituted by the engagement of the chain configuration and the sprocket configuration, and it is possible to smoothly transmit the depressing force of the pedal similarly to the above embodiment. Become. In this case, it goes without saying that the chain may be directly attached to the fixed gear 60.
この変形例によれば、 嚙み合い装置を、 チェーン 'アンド 'スプロケッ トの嚙み合い形態で形成しているため、 走行中に砂利等がチェーン形態 - スプロケット形態の嚙み合い部に嚙み込むのを防止でき、 安全走行を確保 でき、 また、 内転歯車あるいは固定歯車をコスト安価に形成でき、 且つ、 重量低減を図ったクランク装置、乗り物等を得ることができるようになる。 また、 上記嚙み合い装置の別の変形例として、 図 1 9に示すように、 固 定歯車としては、 スプロケット歯 6 2 aを有するスプロケット形態の固定 歯車 6 2に形成し、 この固定歯車 6 2の内側を回る内転歯車として、 上記 スプロケッ ト歯 6 2 aに嚙み合うピン状の歯 6 3 aを設けたチェーン形 態の内転歯車 6 3に形成する変形例とすることもできる。なお、この場合、 内転歯車 6 3にチェーンを直接に設ける態様にしてもよいのは勿論であ る。 According to this modification, since the engaging device is formed in the form of a chain 'and' sprocket, gravel or the like is trapped in the chain-sprocket configuration during traveling. Can be prevented, and safe running can be ensured. Additive gears or fixed gears can be formed at low cost, and It is possible to obtain a crank device, a vehicle, and the like with a reduced weight. As another modified example of the engaging device, as shown in FIG. 19, the fixed gear is formed as a sprocket-shaped fixed gear 62 having sprocket teeth 62 a. As an add-on gear rotating inside of 2, it is also possible to adopt a modification example in which the add-on gear 63 in the form of a chain is provided with pin-shaped teeth 63 a that mesh with the sprocket teeth 62 a. . In this case, it goes without saying that the chain may be provided directly on the adduction gear 63.
この変形例によれば、 嚙み合い装置を、 チェーン 'アンド 'スプロケッ トの嚙み合い形態で形成しているため、 走行中に砂利等がチェーン形態 ' スプロケット形態の嚙み合い部に嚙み込むのを防止でき、 安全走行を確保 でき、 また、 内転齒車あるいは固定歯車をコスト安価に形成でき、 且つ、 重量低減を図ったクランク装置、乗り物等を得ることができるようになる。 また、 上記実施形態では、 回転力取り出し手段としての原動スプロケッ ト 7を円形状の形態のものを使用したが、 この代わりに楕円形状のスプロ ケットを使用することも可能である。 かかる変形例によれば、 ペダルを下 方に踏み込むときの速度変化をキヤンセルして平均化した速度にでき、安 定した踏み込み操作フィーリングを得ることができるようになる。  According to this modification, the engaging device is formed in the form of a chain 'and' sprocket, so that gravel or the like is trapped in the engaging portion of the chain form 'sprocket' during traveling. This makes it possible to obtain a crank device, a vehicle, and the like, which can reduce the weight by reducing the cost of the adduction gear or the fixed gear. Further, in the above embodiment, the driving sprocket 7 as the rotating force extracting means has a circular shape, but an elliptical sprocket may be used instead. According to this modified example, the speed change when the pedal is depressed downward can be canceled to obtain an averaged speed, and a stable depressing operation feeling can be obtained.

That is, the mounting shaft of the handle-type pedal is engaged with a track guiding section having, for example, a curved shape, an elliptical shape, a polygonal shape, or a linear shape, and is always located near the lowermost position deviated in the track guiding portion. For this reason, the part where the adduction gear and fixed gear come into contact with each other (contact point) is used as a fulcrum, and the handle-type pedal or the mounting shaft of a manual pedal installed at a location away from the handle remains (engagement). When a driving force is applied to the lowermost part of the orbital guiding part that rotates, a rotating moment acts on the internal gear by leverage, and the internal gear starts rolling smoothly, and the crankshaft rotates. Vehicles such as hand-type bicycles and wheelchairs can be moved by applying thrust through means for taking out rotational force such as sprockets. Therefore, there is an effect that even an elderly person or a handicapped person who cannot exert sufficient leg strength can easily operate the hand cycle and run.
