Abstract

PROBLEM TO BE SOLVED: To provide a bicycle pedal capable of unconsciously performing bow-leg correction in daily life.SOLUTION: The bicycle pedal 1 is configured to incline a step-on surface 5 on which a foot is put, downwards from outside to inside and to incline the outside of the step-on surface 5 downwards from the rear side to the front side when the inside of the step-on surface 5 is set substantially in parallel in a front and back direction. With this configuration, when the bicycle pedal 1 is stepped on, an ankle joint is flexed by the inclination in the front and back direction of the outside of the step-on surface 5, so that the ankle joint becomes hard to turn and a knee joint other than the ankle joint has to be flexed in order to make a plantar surface follow the inclination in the in-and-out direction of the step-on surface 5, and thereby load in the valgus direction can be effectively added to an inverted knee joint of the bow leg.

Description

本発明は、自転車用ペダルに関する。   The present invention relates to a bicycle pedal.

従来、足を載せる踏込面部を外側から内側に下り傾斜させた自転車用ペダルが知られている（例えば、特許文献１，２）。しかしながら、これらのペダルは漕ぎ易さを目的としているものである。これらのペダルでは、ペダルを踏み込む際に、踏込面部の傾斜によって踵骨が回内するだけであるため、Ｏ脚の根本原因である膝関節に負荷がほとんど加わらず、Ｏ脚矯正の効果を得ることはできない。   2. Description of the Related Art Conventionally, bicycle pedals in which a stepping surface portion on which a foot is placed are inclined downward from the outside to the inside are known (for example, Patent Documents 1 and 2). However, these pedals are intended for ease of rowing. In these pedals, when the pedal is depressed, the rib is merely circulated by the inclination of the depression surface portion, so that the knee joint that is the root cause of the O leg is hardly loaded, and the effect of O leg correction is obtained. It is not possible.

一方で、Ｏ脚を矯正するために、様々な矯正器具が開発されている。しかしながら、こうした器具は、定期的に当該器具を使用する時間を設ける必要があるため長続きしないことが多い。   On the other hand, various orthodontic appliances have been developed to correct the O-leg. However, such instruments often do not last long because of the need to provide time to use them regularly.

実開昭５０−８４９４９号公報Japanese Utility Model Publication No. 50-84949 特開２００７−９９２０３号公報JP 2007-99203 A

本発明は、かかる現状に鑑みてなされたものであり、意識せずに日常生活の中でＯ脚矯正を行うことのできる自転車用ペダルの提供を目的とする。   The present invention has been made in view of the present situation, and an object of the present invention is to provide a bicycle pedal that can perform O-leg correction in daily life without consciousness.

本発明は、足を載せる踏込面部が、外側から内側に下り傾斜しており、さらに、該踏込面部の内側部分を前後方向に略水平にした時に、踏込面部の外側部分が、後側から前側に下り傾斜することを特徴とする自転車用ペダルである。なお、ここでいう踏込面部の傾斜方向は、踏込面部を上向きにした状態における傾斜方向を指す。   In the present invention, the stepping surface portion on which the foot is placed is inclined downward from the outside to the inside, and when the inner portion of the stepping surface portion is substantially horizontal in the front-rear direction, the outer portion of the stepping surface portion is moved from the rear side to the front side. The bicycle pedal is characterized by being inclined downward. In addition, the inclination direction of the stepping surface part here refers to the inclination direction in a state where the stepping surface part faces upward.

かかる構成にあっては、踏込面部に足の前側部分を載せて踏み込む時に、踏込面部の内外方向及び前後方向の傾斜によって、親指の付け根でつま先立ちをするように足底面が傾くこととなる。この時、足関節は、かかる足底面の傾きを実現するために、踵骨の回内だけでなく、底屈と外転まで行うこととなり、かかる足関節の動きによって、Ｏ脚の内反した膝関節に対して外反方向の負荷を効果的に加えることができる。したがって、本発明のペダルを自転車に取り付ければ、自転車を漕いでいるだけでＯ脚を矯正することができる。   In such a configuration, when the front part of the foot is placed on the stepping surface part and stepped on, the bottom surface of the foot tilts so that the toe stands at the base of the thumb due to the inclination of the stepping surface part in the inside / outside direction and the front / rear direction. At this time, in order to realize the inclination of the bottom of the foot, the ankle joint does not only the pronation of the ribs but also the plantar flexion and abduction. A load in the valgus direction can be effectively applied to the knee joint. Therefore, if the pedal of the present invention is attached to a bicycle, the O-leg can be corrected just by stroking the bicycle.

本発明にあって、踏込面部の内側に、該踏込面部から隆起して踏込面部に載せた足を内側から支持する内側支持部が形成されていることが提案される。かかる構成にあっては、踏込面部に載せた足が内側支持部によって内側から支持されるため、踏込面部が傾斜していても、踏込面部から足をずらすことなく、踏込面部を繰り返して確実に踏み込むことが可能となる。   In this invention, it is proposed that the inner side support part which protrudes from this stepping surface part and supports the leg | foot which mounted on the stepping surface part from the inner side is formed inside the stepping surface part. In such a configuration, since the foot placed on the stepping surface portion is supported from the inside by the inner support portion, even if the stepping surface portion is inclined, the stepping surface portion can be reliably repeated without shifting the foot from the stepping surface portion. It becomes possible to step in.

以上に述べたように、本発明によれば、自転車を漕いでいるだけで、Ｏ脚矯正の効果が得られるから、日常の５〜３０分程度の通勤、通学や買物などの移動時間を利用してＯ脚矯正を行うことができる。一般的に、Ｏ脚矯正器具の使用は長続きしない傾向があるが、かかる自転車用ペダルは、日常的に自転車に乗っている人であれば、日常生活の一環として意識することなく習慣的に使用可能であるため、無理なく長続きさせることができる。   As described above, according to the present invention, the effect of O-leg correction can be obtained just by riding a bicycle, so the daily travel time such as commuting, attending school or shopping is used for about 5 to 30 minutes. O-leg correction can be performed. In general, the use of O-leg correctors tends not to last long, but if you are riding a bicycle on a daily basis, you can use this pedal as a habit without being aware of it as part of your daily life. Because it is possible, it can be continued without difficulty.

本発明の実施形態を、以下の実施例に従って説明する。
実施例の自転車用ペダル１は、図１に示すように、左右一対の肉厚板状のペダル本体２，２と、各ペダル本体２を自転車のクランクＸに固定するペダルシャフト３，３とを備えて成る。 Embodiments of the present invention are described according to the following examples.
As shown in FIG. 1, the bicycle pedal 1 of the embodiment includes a pair of left and right thick plate-like pedal bodies 2, 2, and pedal shafts 3, 3 that fix each pedal body 2 to the crank X of the bicycle. Be prepared.

以下、ペダル本体２の構成について説明するが、左右一対のペダル本体２は対称形状であるため、左方のもののみを示す図面を参照して説明する。
ペダル本体２は、硬質樹脂で構成されており、図２に示すように、内側と外側が肉厚で、中央が比較的肉薄となった括れた板形状をなしている。ペダル本体２には、図３，４に示すように、ペダルシャフト３を幅方向に挿通させる挿通孔４が形成されており、ペダル本体２は、ペダルシャフト３によって幅方向に軸支され、ペダルシャフト３を中心に回転可能となっている。 Hereinafter, the configuration of the pedal body 2 will be described. Since the pair of left and right pedal bodies 2 have a symmetrical shape, the description will be made with reference to the drawings showing only the left one.
The pedal body 2 is made of a hard resin, and has a constricted plate shape in which the inner and outer sides are thick and the center is relatively thin as shown in FIG. As shown in FIGS. 3 and 4, the pedal body 2 is formed with an insertion hole 4 through which the pedal shaft 3 is inserted in the width direction. The pedal body 2 is pivotally supported by the pedal shaft 3 in the width direction. The shaft 3 is rotatable.

ペダル本体２は、挿通孔４に対して回転対称形状をなしており、その両面に、足を載せる踏込面部５が形成されて、いずれかの踏込面部５を上向きにして使用するよう構成されている。踏込面部５は、ペダル本体２の外側縁から中央部に亘って形成されており、踏込面部５の内側は、踏込面部５から隆起して、踏込面部５に載せた足を内側から支持する内側支持部６を形成している。また、踏込面部５及び内側支持部６の表面には、滑止め防止溝７が格子状に形成されている。   The pedal body 2 has a rotationally symmetric shape with respect to the insertion hole 4, and a stepping surface portion 5 on which a foot is placed is formed on both surfaces of the pedal body 2, and any one of the stepping surface portions 5 faces upward. Yes. The stepping surface portion 5 is formed from the outer edge to the center portion of the pedal body 2, and the inside of the stepping surface portion 5 protrudes from the stepping surface portion 5 and supports the foot placed on the stepping surface portion 5 from the inside. A support portion 6 is formed. Further, anti-skid grooves 7 are formed in a lattice pattern on the surfaces of the stepping surface portion 5 and the inner support portion 6.

本実施例にあって、踏込面部５は、図２，３に示すように、上向きにした状態で、外側から内側に下り傾斜している。また、その傾斜は、外側ほど急峻で、内側ほど緩やかとなっている。   In this embodiment, as shown in FIGS. 2 and 3, the stepping surface portion 5 is inclined downward from the outside to the inside in an upward state. Further, the inclination is steeper toward the outside and gentler toward the inside.

また、踏込面部５は、図３，５，図６（ａ）に示すように、その内側部分を水平にした時に、その外側部分が後側から前側に５°程度下り傾斜している。この下り傾斜は、踏込面部５の外側ほど傾斜が急峻になるようになっている。   Further, as shown in FIGS. 3, 5, and 6 (a), the stepping surface portion 5 is inclined downward by about 5 ° from the rear side to the front side when the inner side portion is leveled. The downward inclination is steeper toward the outside of the stepping surface portion 5.

かかる構成によれば、図７に示すように、踏込面部５に足の前側部分を載せてペダル本体２を踏み込むと、踏込面部５の傾斜面の案内作用によって、親指の付け根でつま先立ちをするように足底面が回転することとなる。この時、足関節が、回内だけでなく、底屈及び外転するように動くことで、膝関節には外反方向の負荷が加わることとなる。   According to such a configuration, as shown in FIG. 7, when the pedal body 2 is stepped on with the front portion of the foot placed on the stepping surface portion 5, the toe stands at the base of the thumb by the guiding action of the inclined surface of the stepping surface portion 5. The bottom of the foot will rotate. At this time, the ankle joint moves not only in the pronation but also in the buckling and abduction, so that a load in the valgus direction is applied to the knee joint.

このように、本実施例の自転車用ペダル１では、自転車を漕ぐときに、膝を外反させる方向に適切に負荷を加えることができるから、Ｏ脚の傾向がある人であれば、本実施例の自転車用ペダル１を装着した自転車に習慣的に乗ることによって、Ｏ脚の内反した膝を適切に矯正でき、ひいては、Ｏ脚に起因する骨盤の歪みも補正することが可能となる。   As described above, in the bicycle pedal 1 of the present embodiment, when a bicycle is ridden, a load can be appropriately applied in the direction in which the knee is reversed. By habitually riding a bicycle equipped with the bicycle pedal 1 of the example, it is possible to appropriately correct the knee that is inversion of the O-leg, and it is also possible to correct the pelvic distortion caused by the O-leg.

特に、本実施例では、踏込面部５の内側に形成された内側支持部６が、踏込面部５に載せた足を内側から支持するため、傾斜した踏込面部５を繰返し踏み込んでも、踏込面部５に載せた足が不適切な位置にずれることがなく、膝関節に適正な負荷を確実に加えることができるという利点がある。   In particular, in the present embodiment, the inner support portion 6 formed on the inner side of the stepping surface portion 5 supports the foot placed on the stepping surface portion 5 from the inner side. Therefore, even if the inclined stepping surface portion 5 is repeatedly stepped on, the stepping surface portion 5 There is an advantage that an appropriate load can be reliably applied to the knee joint without shifting the placed foot to an inappropriate position.

なお、本発明の自転車用ペダルは、上記実施例の形態に限らず本発明の要旨を逸脱しない範囲内において種々変更を加えることが可能である。例えば、実施例の自転車用ペダル１では、ペダル本体２の両面に踏込面部５が形成されていたが、本発明に係る踏込面部は、ペダル本体の一面に形成されていれば足りる。また、ペダル本体に、踏込面部に載せた足を保持する被甲部を設けるようにしてもよい。   The bicycle pedal of the present invention is not limited to the embodiment described above, and various modifications can be made without departing from the spirit of the present invention. For example, in the bicycle pedal 1 of the embodiment, the stepping surface portions 5 are formed on both surfaces of the pedal body 2, but the stepping surface portion according to the present invention only needs to be formed on one surface of the pedal body. Moreover, you may make it provide a backed part which hold | maintains the leg mounted on the stepping surface part in the pedal main body.
