［第１の実施形態］
図１は、本発明の第１の実施形態における履物１の外観を示す斜視図である。図２は、図１の正面図である。履物１は、所謂、ビーチサンダルであり、足台１０と、鼻緒２０と、を備えている。なお、図１、図２は、使用者の左足に履かせる履物１を示しており、右足に履かせる履物１は左足に履かせる履物１に対して左右対称であるため、右足に履かせる履物１についての詳細な説明は省略する。また、 [First Embodiment]
FIG. 1 is a perspective view showing the appearance of footwear 1 according to the first embodiment of the present invention. 2 is a front view of FIG. 1. FIG. The footwear 1 is a so-called beach sandal, and includes a footrest 10 and a thong 20. - 特許庁1 and 2 show the footwear 1 worn on the left foot of the user, and the footwear 1 worn on the right foot is bilaterally symmetrical with respect to the footwear 1 worn on the left foot. A detailed description of 1 is omitted. again,

足台１０は、ゴム材やＥＶＡウレタン材等によって構成され、足の外周をかたどってなる平板状の部材であり、使用者の踵が載せられる踵部１０ａと、使用者のつま先が載せられるつま先部１０ｂと、を備えている。 The footrest 10 is made of rubber material, EVA urethane material, or the like, and is a flat plate-shaped member shaped like the outer circumference of the foot. a portion 10b;

鼻緒２０は、布や合成樹脂によって構成され、前緒部２１と、横緒部２２と、によって構成されている。前緒部２１は、足台１０の板面から上方に延びて、使用者の足の親指と人差し指とによって挟まれる部分であり、足台１０のつま先部１０ｂに配置されている。横緒部２２は、布製や合成樹脂製の紐状或いは帯状の部材によって構成されており、前緒部２１を基端として足台１０における親指側の側部（以下、内側側部と称する）に向かって延びる内横緒部２２ａと小指側の側部（以下、外側側部と称する）に向かって延びる外横緒部２２ｂとの２つに分かれている。内横緒部２２ａ及び外横緒部２２ｂの終端部は、足台１０の足踏まずの領域の両側部にそれぞれ固定される。 The strap 20 is made of cloth or synthetic resin and comprises a front strap portion 21 and a horizontal strap portion 22 . The front cord portion 21 extends upward from the plate surface of the footrest 10 and is a portion sandwiched between the user's big toe and forefinger, and is arranged at the toe portion 10b of the footrest 10 . The lateral strap portion 22 is formed of a string-like or belt-like member made of cloth or synthetic resin. It is divided into two parts, that is, an inner lateral cord portion 22a extending toward the finger and an outer lateral cord portion 22b extending toward the little finger side portion (hereinafter referred to as an outer lateral portion). The end portions of the inner and outer cord portions 22a and 22b are fixed to both sides of the foot rest area of the footrest 10, respectively.

足台１０は、前緒部２１に対して小指側に欠落部１０ｃを更に備えている。欠落部１０ｃは、足台１０におけるつま先側の端部から足台１０の長手方向に沿って切れ目を入れ、前緒部２１に対して若干小指寄りの部位を通り、外横緒部２２ｂの終端部に対して若干つま先寄りの部位を通って、足台１０における外側側部まで緩やかな弧状に切断することによって形成される。 The footrest 10 further includes a missing portion 10c on the little finger side of the front strap portion 21. - 特許庁The missing portion 10c is cut along the longitudinal direction of the footrest 10 from the toe-side end of the footrest 10, passes through a portion slightly closer to the little finger than the front cord portion 21, and ends at the outer lateral cord portion 22b. It is formed by cutting in a gentle arc to the outer side of the footrest 10 through a portion slightly closer to the toe than the foot.

次に、使用者が履物１を履いた状態について説明する。 Next, a state in which the user wears the footwear 1 will be described.

このように構成された履物１は、使用者が鼻緒２０に足を通し、使用者の足の親指と人差し指との間に前緒部２１を挟めることによって履くことができる。このとき、内横緒部２２ａが使用者の親指の付け根を通り、外横緒部２２ｂが使用者の足の甲を通ることで、履物１が使用者の足から外れ難くなる。 The footwear 1 constructed in this way can be put on by the user putting the foot through the thong 20 and pinching the front thong 21 between the user's big toe and forefinger. At this time, the inner side strap portion 22a passes through the base of the user's big toe, and the outer side strap portion 22b passes through the instep of the user, thereby making it difficult for the footwear 1 to come off the user's foot.

使用者が履物１を履いた状態において、使用者の足の中指、薬指、小指及びこれらの付け根部分と、当該付け根部分に対して踵寄りに位置する母趾内転筋横頭の部分と、短小趾屈筋における土踏まずの側方の部分とに欠落部１０ｃが対向する。つまり、足裏を土踏まず付近でつま先側と踵側とに２分割し、このうちつま先側を更に親指側（内側）と小指側（外側）とに分割した場合に、つま先側の外側半分の部位が、欠落部１０ｃに概ね対向する。 When the user wears the footwear 1, the middle finger, the ring finger, the little finger, and the root portion of the user's foot, the portion of the lateral head of the adductor hallucis muscle located near the heel with respect to the root portion, The missing portion 10c faces the portion of the flexor brevis muscle on the side of the arch of the foot. In other words, when the sole is divided into the toe side and the heel side near the arch of the foot, and the toe side is further divided into the big toe side (inner side) and the little finger side (outer side), the outer half of the toe side generally faces the missing portion 10c.

このため、使用者が履物１を履いて歩行した場合、足裏におけるつま先側の外側半分の部位が地面から離間するため、使用者の体重は、使用者の足裏の内側側部に集中する。また、使用者は、直立や歩行の際に、欠落部１０ｃが対向している足裏の外側部分が地面に付かないように意識を持つようになる。これにより、使用者の脚の重心を内側に補正することが可能になり、使用者がＯ脚であれば、使用者の膝の間隔を狭くすることが可能になる。 Therefore, when the user wears the footwear 1 and walks, the outer half of the sole on the toe side is separated from the ground, and the user's weight is concentrated on the inner side of the user's sole. . In addition, the user becomes conscious of not contacting the ground with the outer portion of the sole facing the missing portion 10c when standing upright or walking. As a result, the center of gravity of the user's legs can be corrected inward, and if the user has bow legs, the distance between the user's knees can be narrowed.

このように構成された本実施形態によれば、使用者が履くことにより、使用者の体重が足裏の内側側部に集中するため、使用者の脚の重心を内側に補正することが可能になり、使用者の膝の間隔を狭くすることが可能になる。これにより、海辺で水着に着替えている場合に、使用者はＯ脚を余り気にせずに歩くことが可能になる。なお、本実施形態によれば、足裏の外側にできた魚の目にスピール膏を貼着した場合、履物１を履くことにより、スピール膏を貼着した部位を地面から離間させることができるため、歩行の際にスピール膏がずれたり剥がれたりすることを低減できる効果も期待できる。 According to this embodiment configured in this way, when the user wears the shoe, the user's weight is concentrated on the inner side of the sole, so the center of gravity of the user's leg can be corrected inward. It becomes possible to narrow the distance between the user's knees. This allows the user to walk without worrying too much about bow legs when changing into a bathing suit at the beach. In addition, according to this embodiment, when Spiel plaster is applied to the corn on the outside of the sole, the footwear 1 allows the area where Spiel plaster is applied to be separated from the ground. It is also expected to have the effect of reducing slippage and peeling of the peel plaster during walking.

［第１の実施形態の変形例］
図３は、本発明の第１の実施形態の変形例における履物２の外観を示す斜視図である。第１の実施形態の変形例における履物２は、図１に示す第１の実施形態における履物１の足台１０に、踵の部分を欠落させた欠落部１０ｄを更に形成したものである。この欠落部１０ｄは、踵欠落部と呼ぶことができる。 [Modification of First Embodiment]
FIG. 3 is a perspective view showing the appearance of footwear 2 in a modified example of the first embodiment of the present invention. The footwear 2 according to the modified example of the first embodiment is the footrest 10 of the footwear 1 according to the first embodiment shown in FIG. This missing portion 10d can be called a heel missing portion.

このように構成された第１の実施形態の変形例によれば、履物２は欠落部１０ｄを有することにより、使用者はつま先立ちで歩くような格好になり、履物２を履いて歩くことよって、自然にふくらはぎ、太腿の裏から尻にかけての筋肉を鍛錬することが可能になる。また、履物２は欠落部１０ｃを有することにより、上述した、使用者の脚の重心を内側に補正することが可能になり、使用者がＯ脚であれば、使用者の膝の間隔を狭くすることが可能になる。 According to the modified example of the first embodiment configured in this manner, the footwear 2 has the missing portion 10d, so that the user can walk on tiptoes, and by wearing the footwear 2 and walking, It is possible to naturally train the muscles from the back of the calf to the buttocks. In addition, since the footwear 2 has the missing portion 10c, it is possible to correct the center of gravity of the user's leg inward as described above, and if the user has bow legs, the distance between the user's knees can be narrowed. it becomes possible to

足台１５は、第１層１６と第２層１７との２層構造である。第１層１６は、欠落部１６ａを有する。また、第１層１６は、第１の実施形態における履物１に係る足台１０のつま先の角部に面取りを施した以外は同一もしくは厚さが異なる形状であり、欠落部１６ａは、履物１に係る足台１０の欠落部１０ｃと同じ部位に形成されている。 The footrest 15 has a two-layer structure consisting of a first layer 16 and a second layer 17 . The first layer 16 has a missing portion 16a. The first layer 16 has the same shape or a different thickness except that the corners of the toes of the footrest 10 according to the footwear 1 in the first embodiment are chamfered. It is formed in the same part as the missing part 10c of the footrest 10 according to .

第２層１７は、第１層１６において欠落部１６ａが形成されてない、足の外周をかたどった形状である。足台１５は、第１層１６の下面と第２層１７の上面とを接着することによって構成され、欠落部１６ａの部位に段差が形成される。 The second layer 17 has a shape that resembles the outer circumference of the foot, in which the missing portion 16a is not formed in the first layer 16 . The footrest 15 is configured by bonding the lower surface of the first layer 16 and the upper surface of the second layer 17, and a step is formed at the missing portion 16a.

履物３は、足台１５に、第１の実施形態における履物１と同様に鼻緒２０を取り付けることによって完成する。 The footwear 3 is completed by attaching a thong 20 to the footrest 15 in the same manner as the footwear 1 in the first embodiment.

使用者が履物３を履いたとき、使用者の足裏におけるつま先側の外側部分が欠落部１６ａによる段差分だけ離間して第２層１７の上面に対向する。 When the user puts on the footwear 3, the outer portion of the user's sole on the toe side faces the upper surface of the second layer 17 with a gap corresponding to the step formed by the missing portion 16a.

このため、第２の実施形態における履物３は、第１の実施形態における履物１と同様に、使用者が履物１を履いて直立した場合、使用者の体重が、使用者の足裏の内側側部に集中する。これにより、使用者の脚の重心を内側に補正することが可能になり、使用者がＯ脚であれば、使用者の膝の間隔を狭くすることが可能になる。また、欠落部１６ａの下方が第２層１７によって覆われているため、履物３を砂浜で使用する場合に、砂浜の砂に足裏が直接触れることがなくなる。 Therefore, in the footwear 3 of the second embodiment, as with the footwear 1 of the first embodiment, when the user wears the footwear 1 and stands upright, the user's weight is distributed to the inside of the user's sole. Concentrate on the sides. As a result, the center of gravity of the user's legs can be corrected inward, and if the user has bow legs, the distance between the user's knees can be narrowed. Moreover, since the lower part of the missing part 16a is covered with the second layer 17, when the footwear 3 is used on a sandy beach, the soles of the feet do not directly touch the sand of the sandy beach.

［第２の実施形態の変形例］
第２の実施形態の履物３は、足台１５の第１層１６と第２層１７との上下を入れ替えて、第２層１７を上層とし、第１層１６を下層としてもよい。 [Modification of Second Embodiment]
In the footwear 3 of the second embodiment, the first layer 16 and the second layer 17 of the footrest 15 may be reversed so that the second layer 17 is the upper layer and the first layer 16 is the lower layer.

このように構成された第２の実施形態の変形例でも、第２の実施形態の履物３と同様の作用効果を奏する。 The modified example of the second embodiment configured in this way also has the same effects as the footwear 3 of the second embodiment.

また、第２の実施形態の履物３においても、第１の実施形態の変形例の履物２と同様に、足台１５における踵の部位を欠落させてもよい。これにより、使用者はつま先立ちで歩くような格好になり、自然にふくらはぎ、太腿の裏から尻にかけての筋肉を鍛錬することが可能になる。また、図３に示す例では踵の部位を円弧状に欠落させているが、図６に示すように、直線上に欠落させてもよい。 Also, in the footwear 3 of the second embodiment, the heel portion of the footrest 15 may be omitted, as in the footwear 2 of the modified example of the first embodiment. This makes it possible for the user to walk on tiptoes and naturally train the muscles of the calves, the back of the thighs and the buttocks. Also, in the example shown in FIG. 3, the heel portion is cut off in an arc shape, but it may be cut off in a straight line as shown in FIG.

また、図３、図６に示すように踵の部位を円弧状に欠落させた履物の下面に、第２の実施形態の履物３における第２層１７を接着して、２層に構成してもよい。これにより、砂浜の砂に踵が直接触れることがなくなる。 Further, as shown in FIGS. 3 and 6, the second layer 17 of the footwear 3 of the second embodiment is adhered to the lower surface of the footwear from which the heel portion is cut in an arc shape to form a two-layer structure. good too. This eliminates direct contact of the heel with sand on the beach.

なお、第２の実施形態及びその変形例においては、足台１５が２層に形成されているが、足台における使用者の足裏の外側部分が対向する部位に、板厚を薄くした薄肉部を形成したものであれば、１層（単板）であってもよい。 In the second embodiment and its modification, the footrest 15 is formed in two layers. A single layer (single plate) may be used as long as it forms a part.

以上、本発明の実施形態について説明したが、本発明の実施形態は上述した実施形態に限るものではない。例えば、上述した実施形態は、ビーチサンダルを例として説明したが、草履に適用することも可能である。また、足板は、ゴム材やＥＶＡウレタン材等によって構成されているが、足板の材質はそれに限るものではない。例えば、木材で構成してもよい。 As mentioned above, although embodiment of this invention was described, embodiment of this invention is not restricted to embodiment mentioned above. For example, in the above-described embodiments, flip-flops are used as an example, but they can also be applied to sandals. Also, the foot plate is made of rubber material, EVA urethane material, or the like, but the material of the foot plate is not limited thereto. For example, it may be made of wood.
