以下に、本発明に係る実施の形態について添付図面を参照しながら詳細に説明する。以下では、全ての図面において同様の要素には同一の符号を付し、重複する説明を省略する。また、本文中の説明においては、必要に応じそれ以前に述べた符号を用いるものとする。 Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. In the following, similar elements are designated by the same reference numerals in all drawings, and duplicate description will be omitted. In addition, in the explanation in the text, the reference numerals described earlier shall be used as necessary.

図１は、本発明に係る実施形態の自転車用ペダル１０を示す図である。図１（ａ）は、自転車用ペダル１０の平面図であり、図１（ｂ）は、自転車用ペダル１０に対して進行方向を向いて見た場合（図１（ａ）の矢印Ａ方向から見た場合）の正面図である。 FIG. 1 is a diagram showing a bicycle pedal 10 according to an embodiment of the present invention. 1 (a) is a plan view of the bicycle pedal 10, and FIG. 1 (b) is a view facing the direction of travel with respect to the bicycle pedal 10 (from the direction of arrow A in FIG. 1 (a)). It is a front view of (when viewed).

図２は、本発明に係る実施形態の自転車用ペダル１０に自転車の運転者であるユーザの靴２を載せている状態を示す図である。図２（ａ）は、図１（ａ）の矢印Ｂ方向から見た自転車用ペダル１０の側面図である。 FIG. 2 is a diagram showing a state in which shoes 2 of a user who is a bicycle driver are placed on the bicycle pedal 10 of the embodiment according to the present invention. FIG. 2A is a side view of the bicycle pedal 10 as viewed from the direction of arrow B in FIG. 1A.

自転車は、ユーザの運転操作により人力で駆動され走行する車両であって、前輪と後輪の車輪を有し、サドルを備え、自転車用ペダル１０上のユーザの脚力で推進される車両である。 A bicycle is a vehicle that is manually driven and traveled by a user's driving operation, has front and rear wheels, has a saddle, and is propelled by the user's leg force on a bicycle pedal 10.

自転車のドライブ・トレインは、自転車用クランク、軸受、チェーンホイール、チェーン、スプロケット、フリーホイールなどによって構成される。また、ユーザの足によって回転される自転車用クランクはボトムブラケット（ＢＢ）と呼ばれる軸受け構造で支持される。自転車用クランクの回転はローラーチェーンとスプロケットの組合せにより駆動輪へと伝達される。 Bicycle drivetrains consist of bicycle cranks, bearings, chain wheels, chains, sprockets, freewheels and more. Further, the bicycle crank rotated by the user's foot is supported by a bearing structure called a bottom bracket (BB). The rotation of the bicycle crank is transmitted to the drive wheels by the combination of the roller chain and the sprocket.

運転者（ユーザ）が動力を与えるのには自転車用クランクの先端に回転可能に支持された自転車用ペダル１０で行われる。 Powering by the driver (user) is performed by the bicycle pedal 10 rotatably supported by the tip of the bicycle crank.

一対の補助付勢部材１８は、図２に示されるように、両端部が一対の第１ペダル部１４及び一対の第２ペダル部１６に連結されるように設けられ、一対の第１ペダル部１４及び一対の第２ペダル部１６のいずれか一方がユーザの靴２の裏で押圧されたときに曲げられて付勢力を生じる。 As shown in FIG. 2, the pair of auxiliary urging members 18 are provided so that both ends are connected to the pair of first pedal portions 14 and the pair of second pedal portions 16, and the pair of first pedal portions are connected to each other. When either 14 or the pair of second pedal portions 16 is pressed by the back of the user's shoes 2, it is bent to generate an urging force.

また、一対の補助付勢部材１８は、補助付勢部材１８ａと補助付勢部材１８ｂとを備える。補助付勢部材１８ａと補助付勢部材１８ｂは、図２に示されるように、略Ｖの字又は略Ｕの字形状を有しており、適度な弾力性と強度を有する材質、例えば、ステンレススチールで構成されるものとして説明するが、もちろん、適宜変更してもよい。 Further, the pair of auxiliary urging members 18 includes an auxiliary urging member 18a and an auxiliary urging member 18b. As shown in FIG. 2, the auxiliary urging member 18a and the auxiliary urging member 18b have a substantially V-shaped or substantially U-shaped shape, and are made of a material having appropriate elasticity and strength, for example, stainless steel. Although it is described as being composed of steel, it may be changed as appropriate, of course.

続いて、上記構成からなる自転車用ペダル１０の作用について説明する。一般的に、自転車を駆動するためには、自転車用クランクの先端に回転可能に支持されたペダルに自転車の運転者（ユーザ）が力を加える必要がある。 Subsequently, the operation of the bicycle pedal 10 having the above configuration will be described. Generally, in order to drive a bicycle, it is necessary for the bicycle driver (user) to apply force to a pedal rotatably supported at the tip of the bicycle crank.

ここで、ペダルの漕ぎ始めが一番大きな力を要するため、高齢者などの大きな力を出すことが難しい運転者にとっては労力となることがある。このような課題に対して、本発明の実施形態に係る自転車用ペダル１０は顕著な効果を発揮する。 Here, since the start of pedaling requires the greatest force, it may be laborious for a driver who has difficulty in exerting a large force such as an elderly person. The bicycle pedal 10 according to the embodiment of the present invention exerts a remarkable effect on such a problem.

ユーザが自転車の運転者としてサドルに座り、片足の靴２を地面につけながらもう片方の足の靴２で自転車用ペダル１０に足を載せる。すなわち、靴２を一対の第１ペダル部１４上に載せた状態とする。 The user sits on the saddle as a bicycle driver, puts his foot on the bicycle pedal 10 with the shoe 2 of the other foot while putting the shoe 2 of one foot on the ground. That is, the shoes 2 are placed on the pair of first pedal portions 14.

このまま自転車用ペダル１０を漕ぐように靴２を踏みつけると、一対の第１ペダル部１４がユーザの靴２の裏で押圧されて所定の角度θ１が大きくなるように曲げられて付勢力を生じる。このとき、一対の第１ペダル部１４は、弾力性を有するため、一般的なペダルに比べて、より小さな力で踏みつけることが出来る。 When the shoe 2 is stepped on as if pedaling the bicycle pedal 10 as it is, the pair of first pedal portions 14 are pressed by the back of the user's shoe 2 and bent so as to increase a predetermined angle θ 1 to generate an urging force. .. At this time, since the pair of first pedal portions 14 have elasticity, they can be stepped on with a smaller force than a general pedal.

また、一対の第１ペダル部１４の所定の角度θ１が大きくなると、一対の補助付勢部材１８が縮むようになるため付勢力を生じる。すなわち、一対の第１ペダル部１４及び一対の補助付勢部材１８の付勢力によるエネルギが蓄積される。 Further, when the predetermined angle θ 1 of the pair of first pedal portions 14 becomes large, the pair of auxiliary urging members 18 contracts, so that urging force is generated. That is, the energy generated by the urging force of the pair of first pedal portions 14 and the pair of auxiliary urging members 18 is accumulated.

このまま自転車用ペダル１０を漕ぐと、靴２を踏みつける力が開放されて、これにより、付勢力によりエネルギが開放されて、このエネルギを利用してペダルを押し上げることが出来る。 If the bicycle pedal 10 is pedaled as it is, the force for stepping on the shoe 2 is released, and the energy is released by the urging force, and the pedal can be pushed up by using this energy.

このように、自転車用ペダル１０によれば、ユーザが漕ぎ出す際には、従来に比べて小さな力で踏みつけることができ、この際、蓄積されたエネルギを用いてペダルを押し上げることが出来る。 As described above, according to the bicycle pedal 10, when the user starts rowing, he / she can step on the pedal with a smaller force than before, and at this time, the pedal can be pushed up by using the accumulated energy.

これにより、従来に比べて、より小さな力で自転車を駆動させることができるため、楽に漕ぎ出しをすることができ、また、高齢者や子供などのように比較的力の弱い人が運転する際にも楽に運転することができるという顕著な効果を奏する。 As a result, the bicycle can be driven with a smaller force than before, so that the bicycle can be rowed easily, and when a relatively weak person such as an elderly person or a child drives the bicycle. It also has a remarkable effect of being able to drive comfortably.
