実用新案登録第3164194号Utility model registration No. 3164194

ところが、従来の登山靴やトレッキングシューズにおいて、靴底のソールが突然に剥がれる問題が発生している。このような問題は、靴底のソールを接着する接着剤が高温多湿の環境下で、劣化したことが原因と考えられ、剥がれる際には全面が一気に剥がれるといった現象となることが多い。 However, in conventional hiking shoes and trekking shoes, there is a problem that the sole of the sole suddenly peels off. Such a problem is considered to be caused by the deterioration of the adhesive that adheres the sole of the shoe sole in a hot and humid environment, and when it is peeled off, the entire surface is often peeled off at once.

そして、山の奥深くに分け入る登山やトレッキングで、歩行中にソールの剥がれが生じると、歩行が十分にできない状況となり、遭難等のように、身体の安全にかかわる事態を招く恐れがあった。 Then, if the sole is peeled off during walking during mountain climbing or trekking that goes deep into the mountain, it becomes impossible to walk sufficiently, which may lead to a situation related to physical safety such as a distress.

この発明は、歩行中のソールの剥離を抑制する靴を提供することを目的とするものである。 An object of the present invention is to provide a shoe that suppresses peeling of a sole during walking.

底部材3の下側面には、所定の間隔で凹部34が複数個形成されており、更にその凹部34の内、6つの凹部34には、雌ネジ穴33が更に形成されている。
A bottom member 3 is provided on the lower side of the upper 2, and an insole 7 is placed on the upper side surface 31 of the bottom member 3. A sole 4 is attached to the lower side of the bottom member 3 with an adhesive.
A plurality of recesses 34 are formed on the lower side surface of the bottom member 3 at predetermined intervals, and female screw holes 33 are further formed in the six recesses 34 among the recesses 34.

凹部34は、前後方向と左右方向に、それぞれ等間隔で配置されており、後述するミッドソール5の上側面に形成された凸部53が、凹部34に嵌め合わされる。雌ネジ穴33が形成されている位置は、つま先部分に近い位置、踵部分に近い位置、及び土踏まず部分近傍の位置である。 The recesses 34 are arranged at equal intervals in the front-rear direction and the left-right direction, and the convex portions 53 formed on the upper side surface of the midsole 5, which will be described later, are fitted into the recesses 34. The positions where the female screw holes 33 are formed are a position close to the toe portion, a position close to the heel portion, and a position near the arch portion.

底部材3の下側面に貼り付けられるソール4は、ミッドソール5とアウトソール6とが重なって構成されている。ミッドソール5は、弾性材料で構成されており、クッション材として履き心地を良好とする作用を有する。また、ミッドソール5の周端辺には、上方に立ち上がった側壁部52が全周に渡って形成されており、その内側部分に形成された収容部51に、底部材3を含むアッパー2の底部を収容する構成となっている。 The sole 4 attached to the lower side surface of the bottom member 3 is formed by overlapping the mid sole 5 and the out sole 6. The midsole 5 is made of an elastic material and has an action of improving comfort as a cushioning material. Further, on the peripheral end side of the midsole 5, a side wall portion 52 rising upward is formed over the entire circumference, and the accommodating portion 51 formed in the inner portion thereof of the upper 2 including the bottom member 3. It is configured to accommodate the bottom.

ミッドソール5の上側面には、複数の凸部53が形成されている。凸部53は、前後方向と左右方向に、それぞれ等間隔で配置されており、円柱形状、或いは円錐台形状に形成されている。この凸部53と同じ形状の凹部が、既述の通り、底部材3の下側面に形成されている。そして、複数の凸部53の内、6つの凸部53には、ネジ挿通孔54が形成されている。このネジ挿通孔54は、底部材3に重ねられた際に、雌ネジ穴33に対向する位置にそれぞれ設けられている。 A plurality of convex portions 53 are formed on the upper side surface of the midsole 5. The convex portions 53 are arranged at equal intervals in the front-rear direction and the left-right direction, and are formed in a cylindrical shape or a truncated cone shape. As described above, a concave portion having the same shape as the convex portion 53 is formed on the lower side surface of the bottom member 3. The screw insertion holes 54 are formed in the six convex portions 53 among the plurality of convex portions 53. The screw insertion holes 54 are provided at positions facing the female screw holes 33 when they are stacked on the bottom member 3.

ミッドソール5の下側に貼り付けられるアウトソール6は、少なくともミッドソール5の構成材料よりも硬質の材料で構成されている。図3に示されているように、アウトソール6の下側面には、所定のパターンに形成され、周囲よりも下側に肉厚となっているブロック部62が複数個形成されている。また、雌ネジ穴33及びネジ挿通孔54に対向する位置に、ネジ穴65が形成され、更にその底部にネジ挿通孔64が形成されている。ネジ穴65は、肉厚となっているブロック部62に形成されている。 The outsole 6 attached to the underside of the midsole 5 is made of a material that is at least harder than the constituent material of the midsole 5. As shown in FIG. 3, a plurality of block portions 62 formed in a predetermined pattern on the lower side surface of the outsole 6 and having a wall thickness below the periphery are formed. Further, a screw hole 65 is formed at a position facing the female screw hole 33 and the screw insertion hole 54, and a screw insertion hole 64 is further formed at the bottom thereof. The screw hole 65 is formed in the thick block portion 62.

底部材3とミッドソール5とアウトソール6とは、それぞれ接着剤によって貼り合わされるが、更に、雌ネジ穴33、ネジ挿通孔54、64で形成されたネジ穴に締着ネジ63が挿入される。締着ネジ63のヘッド部は、ネジ穴62内に収容され、アウトソール6の底面から外側に突出せず、地面に直接ヘッド部が接触しない構成となっている。 The bottom member 3, the midsole 5, and the outsole 6 are attached to each other by an adhesive, and a tightening screw 63 is further inserted into a screw hole formed by a female screw hole 33 and a screw insertion hole 54, 64. To. The head portion of the fastening screw 63 is housed in the screw hole 62, does not protrude outward from the bottom surface of the outsole 6, and the head portion does not come into direct contact with the ground.

締着ネジ−63の先端部の雄ネジ部が、雌ネジ穴33に螺合することによって、ソール4が底部材3に固定されるので、ソール4と底部材3とを貼り付けている接着剤が劣化した場合に、ソール4が剥がれることが抑制される。また、この実施形態では、締着ネジ63の締め付けによって、弾性材で構成されたミッドソール5が締め付けられ、圧縮変形するので、その復元力が締着ネジ63に加わり、ネジの緩みの発生が抑制される。特に、ミッドソール5の肉厚となっている凸部53の部分が圧縮変形させられるので、さらに復元力が強くより、緩み抑制効果が、より強くなる。 Since the sole 4 is fixed to the bottom member 3 by screwing the male screw portion at the tip of the fastening screw-63 into the female screw hole 33, the sole 4 and the bottom member 3 are adhered to each other. When the agent deteriorates, the sole 4 is prevented from peeling off. Further, in this embodiment, the tightening of the tightening screw 63 tightens the midsole 5 made of an elastic material and compresses and deforms it, so that the restoring force is applied to the tightening screw 63 and the screw is loosened. It is suppressed. In particular, since the portion of the convex portion 53, which is the wall thickness of the midsole 5, is compressed and deformed, the restoring force is stronger and the loosening suppressing effect is stronger.

なお、雌ネジ穴33、ネジ挿通孔54、64で形成されたネジ穴は、長尺の雄ネジを用いて、靴にアイゼンなど付属部品を取り付けるためのネジ穴として利用してもよい。 The screw holes formed by the female screw holes 33 and the screw insertion holes 54 and 64 may be used as screw holes for attaching accessories such as crampons to shoes by using long male screws.

ミッドソール5とアウトソール6との貼り合せ面にも、凸部53、凹部34と同様の凹凸を設けて嵌め合せる構成としてもよい。 The bonding surface between the midsole 5 and the outsole 6 may also be provided with the same unevenness as the convex portion 53 and the concave portion 34 to be fitted.

以上説明したように本発明に係る靴1は、登山靴、トレッキングシューズとして利用するのが特に有用であるが、他の靴に用いることも可能である。 As described above, the shoe 1 according to the present invention is particularly useful as a mountain climbing shoe or a trekking shoe, but it can also be used for other shoes.
