以上の構成からなる自転車のテコのフリーアーム。
【0005】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
(イ)自転車のチェーンスティ(22)(23)に前部ハンガー(10)と後部ハンガー(11)を設ける。
その間隔は後部フリーホィール(25)の歯数の4倍の歯数をもつ鎖車(5)の半径よりも長くする。鎖車(5)はチェーン(24)にて後輪フリーホィール(25)と連動する。
(ロ)図3は公知の技術のフリーホィール(3)の内部構造の図である。
フリーギャー(26)の正回転でラジエット(29)も正回転すると爪(28)と噛み合い、組み込まれた中子(27)軸(8)に力と正回転を伝える。
フリーギャー(26)が回転を停止している時、軸(8)中子(27)が正回転しても爪(28)はラジエット(29)とは噛み合わず空転をする。
(ハ)フリーホィール(3)のフリーギャー(26)をフリーギャー(26)でなく、形を変えてフリーアーム(1)にする。
フリーアーム(1)を備えたフリーホィール(3)となり、軸(8)の一端に設ける。
他の端部には、フリーアーム(2)を備えたフリーホィール(4)を設ける。フリーアーム(1)(2)を備えたフリーホィール(3)(4)と鎖車(5)は軸(8)を中心とし、鎖車(5)の半径の二倍の長さの一定の処にピン(20)(21)を設ける。
(ニ)クランク(12)(13)と先端クランク(16)(17)を中間軸(14)(15)にて連結すると、屈折クランク(12)(16)と屈折クランク(13)(17)となり、それを前部ハンガー(10)のクランク軸(9)の両端部に互いに180度の角度に取り付ける。先端クランク(16)(17)の他の端部にペタル(18)(19)を設ける。
(ホ)連杆(6)の長さは、屈折クランク(12)(16)がクランク軸(9)上にて直立している時の中間軸(14)と、軸(8)上にフリーアーム(1)を備えたフリーホィール(3)が直立している時のピン(20)との間の長さを連杆(6)の長さとする。
連杆(6)の両端は回転自在に取り付ける。
又、反対側の連杆(7)の長さも連杆(6)と同じ長さにする。
本発明は以上のような構造よりなっている。
本発明を使用するときは、ペタル(18)(19)を踏み込むと中間軸(14)(15)に連結した屈折クランク(12)(16)と屈折クランク(13)(17)の正回転と連杆(6)(7)の作用で普通の自転車の二倍の力で回転し、困難な坂道も、長距離走行も、らくに走行することになる。
自転車のペタル(18)を踏み込むと、クランク軸(9)上に直立している屈折クランク(12)(16)の中間の中間軸(14)に連杆(6)があり、踏み込む力は倍加され、連杆(6)の他の端部は直立している。
フリーアーム(1)のピン(20)を90度横まで正回転に引っ張ると軸(8)を中心としてフリーアーム(1)を備えたフリーホィール(3)も90度正回転すると共に、鎖車(5)も90度正回転する。
鎖車(5)の半径の長さの倍も長いフリーアーム(1)を引っ張ることで力は増大される。これで脚力は二回倍加する。その力は鎖車(5)にて出力する。
中間軸(14)で連結した屈折クランク(12)(16)の回転と、連杆(6)の作用により、フリーアーム(1)を備えたフリーホィール(3)は90度の正転と逆転の往復運動を行う。
その回転の90度の正回転のみを常にフリーホィール(3)にて軸(8)鎖車(5)に伝え、チェーン(24)にて後輪フリーホィール(25)と後輪(30)は一回転する。
ペタル(18)(19)を踏まない時は、フリーアーム(1)を備えたフリーホィール(3)は作用せず、自転車は慢性走行をし、後輪(30)は回転を続け、後輪フリーホィール(25)は空転をする。
ペタル(18)を踏み込むと、上段より下段まで回転する。反対側のペタル(19)と中間軸(15)で連結した屈折クランク(13)(17)は正回転して下段より上段にくるに従い、中間軸(15)に取り付けた連杆(7)の他の端部はフリーアーム(2)を備えたフリーホィール(4)のピン(21)を引っ張るのではなく、反対に押し上げる作用を行うので、フリーアーム(2)を備えたフリーホィール(4)は逆転して横倒の位置から直立の位置まで逆転する。
フリーホィール(4)は逆転すると空転するので、軸(8)には回転を伝えない。その時は中間軸(15)で連結した屈折クランク(13)(17)とフリーアーム(2)を備えたフリーホィール(4)も回転して共に直立の状態になる。
ペタル(19)も上段に来ている。
次に、ペタル(19)を踏み込むと、前に記した通り、ペタル(18)を踏み込んだ時の工程を繰り返すことになる。
自転車の走行はペタル(18)(19)を交互に踏むことである。
屈折クランク(12)(16)、屈折クランク(13)(17)の中間軸(14)(15)の回転で取り付けてある連杆(6)(7)の所にて力は倍加され、180度の差で交互に連動し、その力は連杆(6)(7)の他の端部にてピン(20)(21)を交互に90度の差にて往復運動を繰り返す。
フリーアーム(1)を備えたフリーホィール(3)は直立状態から90度横に倒れ、フリーアーム(2)を備えたフリーホィール(4)は反対に横倒から直立状態まで押し上げる互いに反対の往復運動を行う。
フリーホィール(3)(4)は正逆回転の往復運動から正回転のみを軸(8)鎖車(5)に伝える。
鎖車(5)の半径の長さはフリーアーム(1)(2)の半分なので最初に倍加された力を再び倍加し、その力は鎖車(5)にて連続的に出力する。
ペタル(18)(19)の一回転は後輪(30)を2回転させる、変速機、電動機等を使用せず、平坦地での長距離、長い坂道もらくに走行する。
なお、両側にあるフリーアーム(1)(2)を備えたフリーホィール(3)(4)の間隔は、ペタル(18)(19)の間隔内であり、踏み込むには支障はない。
【0006】
【発明の効果】
本発明を使用することによって、自転車のペタルを踏み力は屈折クランクの中間軸の所にて力は倍加し、連杆にてフリーアームを備えたフリーホィールを90度に引っ張ると長さが半分の半径の鎖車にて力は再び倍加され、90度の正逆回転の往復運動から常にフリーアームを備えたフリーホィールは正回転のみを伝え、軸と鎖車に伝え、チェーンにて後輪に伝えることで平坦地の長距離走行と困難な長い坂道も変速機、電動機を使用しなくとも、らくに走行し得る。

[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
(A) A front hanger (10) and a rear hanger (11) are provided on the chain stays (22) and (23) of the bicycle.
The spacing is longer than the radius of the chain wheel (5) having four times the number of teeth of the rear freewheel (25). The chain wheel (5) is linked with the rear wheel freewheel (25) by a chain (24).
(B) FIG. 3 is a view showing the internal structure of a freewheel (3) of a known technique.
When the radiator (29) rotates forward by the free rotation of the free gear (26), the radiator (29) meshes with the pawl (28), and transmits force and forward rotation to the core (27) shaft (8) incorporated therein.
When the free gear (26) stops rotating, even when the shaft (8) core (27) rotates forward, the pawl (28) does not engage with the radiator (29) and idles.
(C) The freewheel (26) of the freewheel (3) is changed to the freearm (1) instead of the freegirl (26).
A free wheel (3) having a free arm (1) is provided at one end of a shaft (8).
At the other end a freewheel (4) with a free arm (2) is provided. The freewheels (3) (4) with free arms (1) (2) and the chain wheel (5) are fixed around an axis (8) and twice as long as the radius of the wheel chain (5). Pins (20) and (21).
(D) When the cranks (12) and (13) and the tip cranks (16) and (17) are connected by the intermediate shafts (14) and (15), the bending cranks (12) and (16) and the bending cranks (13) and (17) And attached to both ends of the crankshaft (9) of the front hanger (10) at an angle of 180 degrees to each other. At the other end of the tip cranks (16) (17), petals (18) (19) are provided.
(E) The length of the connecting rod (6) is free on the intermediate shaft (14) when the bent cranks (12) and (16) are upright on the crankshaft (9) and on the shaft (8). The length between the freewheel (3) having the arm (1) and the pin (20) when the freewheel (3) is upright is defined as the length of the connecting rod (6).
Both ends of the connecting rod (6) are rotatably mounted.
The length of the connecting rod (7) on the opposite side is also the same as that of the connecting rod (6).
The present invention has the above structure.
When using the present invention, when the petals (18) and (19) are depressed, the refracting cranks (12) and (16) connected to the intermediate shafts (14) and (15) and the positive rotations of the refracting cranks (13) and (17) are changed. By the action of the connecting rods (6) and (7), the bicycle rotates with twice the power of a normal bicycle, and can easily travel on difficult slopes and long distances.
When the pedal (18) of the bicycle is stepped on, the connecting rod (6) is on the intermediate shaft (14) between the bent cranks (12) and (16) standing upright on the crankshaft (9), and the pressing force is doubled. The other end of the connecting rod (6) is upright.
When the pin (20) of the free arm (1) is pulled forward by 90 degrees in the forward direction, the free wheel (3) provided with the free arm (1) also rotates forward by 90 degrees about the shaft (8), and the chain wheel (5) also rotates 90 degrees forward.
The force is increased by pulling on the free arm (1) which is twice as long as the radius of the chain wheel (5). This doubles the leg strength twice. The force is output by a chain wheel (5).
By the rotation of the bending cranks (12) and (16) connected by the intermediate shaft (14) and the action of the connecting rod (6), the freewheel (3) provided with the free arm (1) rotates forward and reverse by 90 degrees. Reciprocating motion.
Only the 90-degree positive rotation of the rotation is always transmitted to the axle (8) chain wheel (5) by the freewheel (3), and the rear wheel freewheel (25) and the rear wheel (30) are transmitted by the chain (24). One rotation.
When the petals (18) and (19) are not stepped on, the freewheel (3) with the free arm (1) does not work, the bicycle runs chronically, the rear wheel (30) continues to rotate, and the rear wheel The freewheel (25) idles.
When the petal (18) is depressed, it rotates from the upper stage to the lower stage. The refracting cranks (13) and (17) connected to the opposite petal (19) by the intermediate shaft (15) rotate forward from the lower stage to the upper stage, and the connecting rod (7) attached to the intermediate shaft (15). The other end does not pull the pin (21) of the freewheel (4) with the free arm (2) but pushes it up, so that the freewheel (4) with the free arm (2) Reverses and reverses from the lying down position to the upright position.
Since the freewheel (4) runs idle when it reverses, it does not transmit rotation to the shaft (8). At that time, the freewheels (4) provided with the free arms (2) and the bending cranks (13) (17) connected by the intermediate shaft (15) also rotate to be in an upright state.
Petal (19) is also at the top.
Next, when the petal (19) is depressed, the steps when the petal (18) is depressed are repeated as described above.
Running a bicycle means stepping on the petals (18) and (19) alternately.
The force is doubled at the connecting rods (6) and (7) attached by the rotation of the intermediate shafts (14) and (15) of the bending cranks (12) and (16) and the bending cranks (13) and (17). The force alternately interlocks with the difference in the degree, and the force alternately reciprocates the pins (20) and (21) at the other end of the connecting rods (6) and (7) with a difference of 90 degrees.
The free wheel (3) with the free arm (1) falls down 90 degrees from the upright position, and the free wheel (4) with the free arm (2) pushes up from the side down to the upright position. Do exercise.
The free wheels (3) and (4) transmit only the forward rotation to the shaft (8) chain wheel (5) from the reciprocating movement of forward and reverse rotation.
Since the radius of the chain wheel (5) is half of that of the free arms (1) and (2), the initially doubled force is doubled again, and the force is continuously output by the chain wheel (5).
One revolution of the petals (18) and (19) rotates the rear wheel (30) twice. The vehicle runs on a flat ground for a long distance and a long slope without using a transmission, an electric motor or the like.
The interval between the free wheels (3) and (4) provided with the free arms (1) and (2) on both sides is within the interval between the petals (18) and (19), and there is no problem in stepping on the pedals.
[0006]
【The invention's effect】
By using the present invention, the stepping force on the bicycle petal is doubled at the middle axis of the bending crank, and the length of the freewheel provided with the free arm by a connecting rod is reduced by half by 90 degrees. The force is doubled again with the wheel with a radius of 90 mm, and the freewheel with the free arm always transmits only forward rotation from the reciprocating motion of 90 degrees forward and reverse rotation, transmits only to the shaft and the wheel, and transmits the rear wheel with the chain. It is possible to travel easily on long flat roads and on difficult long hills without using transmissions and electric motors.
