Description

簡易着脱履物Simple removable footwear
　簡易に着脱できる履物に関するものである。 It relates to footwear that can be easily attached and detached.
　簡易に着脱できる履物については、スリッパやサンダル等のように部分的な甲革、甲帯、鼻緒で保持されるものがよく使用されており、前後左右の区別無く履けるもの、粘着させるもの、足指の間に突起を引っ掛けるもの等、多数のものが存在する。 For footwear that can be easily attached and detached, things that are held by partial uppers, upper belts, snouts, such as slippers and sandals, are often used. There are many things, such as those that hook a protrusion between fingers.
登録実用新案第３０２８０６３号公報Registered Utility Model No. 3028063 米国特許出願公開第２００８／０３０１９７４号US Patent Application Publication No. 2008/0301974
　足指の間に突起を引っ掛けるものは、その使用に熟練を要し、簡単とはいかない。粘着させるものは、装着が簡単である反面、脱ぐときやその扱いに難点がある。スリッパやサンダル等は、歩く動作の流れで足を滑り込ませ、装着が簡単であるが、脱ぐときには、歩く動作の流れのままとはいかず、履物を少し前へ蹴り出すような動作あるいはその場で足踏みするような動作を必要とする。前後左右の区別無く履けるものも同様であり、特に履物中央部のみで保持されるものは、適度な保持力を維持しないと、使用中に履物がずれたり、脱げたりすることになる。 る も の A thing that hooks a protrusion between the toes requires skill to use it and is not easy. The adhesive is easy to install, but has a difficulty in removing and handling. Slippers, sandals, etc. are easy to put on by slipping your foot with the flow of walking, but when you take off, the flow of walking does not remain, but the footwear kicks out a little forward or on the spot Requires a stepping action. The same applies to items that can be worn without distinction between front, back, left, and right, and particularly those that are held only at the center of the footwear will slip or take off during use unless an appropriate holding force is maintained.
　上記課題を解決するために本発明は、足で踏むことにより履物に足を挟持させ、挟持部を中央に取付けた場合はつま先立ち状態により、また端寄りに取付けた場合に、かかと側挟持用として使用する際はつま先立ち状態により、つま先側挟持用として使用する際はかかと立ち状態により履物の挟持を外すことにした。また、足で踏むことにより履物に足を挟持させ、つま先立ち状態により履物の挟持を外すべく、履物中央もしくは全体に挟持部を備えることにする。 In order to solve the above-mentioned problems, the present invention is designed to hold the foot on the footwear by stepping on the foot, and to hold the heel side when the holding portion is attached to the center, or to the heel side when attached to the end. It was decided to remove the footwear depending on the standing state of the toe when used, and the standing state of the heel when used for holding the toe side. In addition, a foot-holding portion is provided at the center of the footwear or in the whole so that the foot is pinched by the footwear by stepping on the foot and the footwear is unfastened by the toe standing state.
　本発明において、歩く動作の流れで足で踏むことにより履物を装着し、歩く動作の流れのなかで意識的につま先立ち状態をつくることにより履物を脱ぐことができる。挟持部を端寄りに取付け、つま先側挟持用として使用する際は、かかと立ち状態により履物を脱ぐので、歩く動作の流れのままとはいかないが、反対側から履物を装着する際には、かかと側挟持用として使用することもでき、いずれの箇所に挟持部を取付けたとしても、前後左右の区別無く履けるものである。使用中、履物は足を挟持しているので、履物がずれたり脱げたりしにくくなる。あえて、挟持部を端寄りに取付け、足のサイズの大きい人がかかと側挟持用として、足のサイズの小さい人がつま先側挟持用として使用し、サイズの大きな違いに対応させることも考えられる。 In the present invention, footwear can be worn by stepping on the foot in the flow of walking motion, and the footwear can be removed by consciously creating a toe standing state in the flow of walking motion. When attaching the gripping part closer to the end and using it for toe side clamping, the footwear will be removed due to the standing state of the heel, so the walking movement will not remain, but when wearing the footwear from the opposite side, the heel It can also be used for side clamping, and it can be worn without any distinction between front, rear, left and right, regardless of where the clamping part is attached. During use, since the footwear holds the foot, it becomes difficult for the footwear to slip and take off. It is also conceivable that the holding part is attached to the end, and a person with a large foot size is used for holding the heel side, and a person with a small foot size is used for holding the toe side to cope with a large difference in size.

　本発明を実施するため、履物の底板に挟持部を取付ける。挟持部は足甲の両側を挟み込むように底板から立ち上がり、適度な剛性と弾性を兼ねた部材にておおまかにはU字やW字に近い構造とする。一定以上の外力を加えることにより多少の塑性変形を生じさせ、使用者の足サイズに合わせられるよう、微調整できるものとしても良い。 In order to carry out the present invention, the holding part is attached to the bottom plate of the footwear. The clamping part rises from the bottom plate so as to sandwich both sides of the instep, and has a structure close to a U-shape or W-shape with a material that has both moderate rigidity and elasticity. A slight plastic deformation may be caused by applying an external force of a certain level or more, and fine adjustment may be made so as to match the foot size of the user.
　挟持部をおおまかにはU字に近い構造とし、U字両上端部から底側に向かって「く」の字形を互いに向かい合わせるように案内板を延ばすと、その上部傾斜は足の踏み込みにより足サイズの多少の違いに対応しつつ一時的にU字の内幅を押し広げ、下部傾斜は使用時の足甲両側を挟み込む役目となる。逆に足を抜き出すときは、下部傾斜が再びU字の内幅を押し広げる役目となる。（実施例１） When the guide plate is extended so that the "C" shape faces each other from the upper end of the U-shape toward the bottom side, the upper slope of the clamping part is The inner width of the U-shape is temporarily expanded to accommodate some differences in size, and the lower slope serves to sandwich both sides of the instep when used. Conversely, when pulling out the legs, the lower slope will play a role in expanding the inner width of the U shape again. Example 1
　挟持部をおおまかにはU字に近い構造とし、U字両上端部から底側に向かって放物線を互いに落とし込むように案内板を延ばすと、そのU字両上端付近は足の踏み込みにより足サイズの多少の違いに対応しつつ一時的にU字の内幅を押し広げ、そこに狭湾部を作りながらU字両側へ押しやられた全体が使用時の足甲両側を挟み込む役目となる。逆に足を抜き出すときは、作られた狭湾部が再びU字の内幅を押し広げる役目となる。また、柔軟な素材における同一案内板は、U字両上端部から互いにアーチ状に重なる形態でも同様に使用でき、この場合は足を水平方向に出し入れする着脱法と兼用可能で、案内板の重なり位置にゴム磁石や磁性体を埋め込めば、両形態の使い分けが容易となる。（実施例２） When the guide plate is extended so that the parabola is dropped from the upper ends of the U-shaped parts toward the bottom side, the sandwiching part is roughly a U-shaped structure. The inner width of the U-shape is temporarily expanded while corresponding to some differences, and the whole pushed to both sides of the U-shape while forming a narrow bay there serves as a role to sandwich both sides of the instep. On the other hand, when pulling out the legs, the narrow bay that is made will play the role of expanding the inner width of the U shape again. In addition, the same guide plate in a flexible material can be used in the same manner in a form that overlaps with each other in an arch shape from both upper ends of the U shape. If a rubber magnet or a magnetic material is embedded in the position, it is easy to use both forms. (Example 2)
　挟持部をU字両上端部内幅が少し狭まったような構造とし、U字両上端部に円柱形もしくは足甲にフィットするよう樽形の縦回転部材を配置すると、その回転部材は足の踏み込みにより足サイズの多少の違いに対応しつつ回転しながら一時的にU字の内幅を押し広げ、かつ使用時の足甲両側を挟み込む役目となる。逆に足を抜き出すときも、逆回転しながら再びU字の内幅を押し広げる役目となる。（実施例３） If the holding part is structured so that the inner width of the U-shaped upper ends is slightly narrowed, and a barrel-shaped vertical rotating member is placed at the upper ends of the U-shaped to fit the columnar or instep, the rotating member will step on the foot. This will temporarily expand the inner width of the U-shape while rotating to accommodate some differences in foot size, and sandwich both sides of the instep when used. On the other hand, when pulling out the legs, it also serves to expand the inner width of the U-shape again while rotating in the reverse direction. (Example 3)
　挟持部をおおまかにはU字に近い構造とし、U字両上端部に三角柱やV字柱に近似した足を受けるような形状の縦回転部材を配置し、上側から底側にかけ約３分の１回転させると、その回転部材は足の踏み込みにより足サイズの多少の違いに対応しつつ回転しながら一時的にU字の内幅を押し広げ、かつ使用時の足甲両側を挟み込む役目となる。逆に足を抜き出すときも、逆回転しながら再びU字の内幅を押し広げる役目となる。（実施例４） The holding part is roughly a U-shaped structure, and a vertical rotation member shaped to receive a leg that approximates a triangular or V-shaped column is placed at the upper end of both U-shaped parts, and it takes about 3 minutes from the top to the bottom. When it is rotated once, its rotating member will temporarily expand the inner width of the U-shape while rotating to accommodate some differences in foot size by stepping on the foot, and sandwich both sides of the instep when used . On the other hand, when pulling out the legs, it also serves to expand the inner width of the U-shape again while rotating in the reverse direction. Example 4
　挟持部をU字両上端部内幅が少し狭まったような構造とし、U字両側内中段にアーチ状を原形とする踏み板をはめ込むと、その踏み板は足の踏み込みにより水平方向に展ばされながら一時的にU字の内幅を押し広げ、その後反転アーチ状態となりU字両上端部との間に足を挟みこむ役目となる。逆に足を抜き出すときも、蓄勢された反発力により再びU字の内幅を押し広げる役目となり、その後原形に戻る。足を水平方向に出し入れする着脱法と兼用可能で、U字両上端部に円柱形もしくは樽形の縦回転部材を配置すると、円滑な足の出し入れに有効である。（実施例５） When the sandwiching part is structured so that the inner width of the upper ends of both U-shapes is slightly narrowed, and a tread board that is shaped like an arch is fitted in the middle part on both sides of the U-shape, the tread board is temporarily extended while being horizontally spread by the foot depressing. The inner width of the U-shape is pushed out, and then it becomes a reverse arch state, which serves to sandwich the foot between both upper ends of the U-shape. Conversely, when pulling out the legs, the accumulated repulsive force will again push the inner width of the U-shape, and then return to the original shape. It can be used as a detaching method that allows the feet to be taken in and out in the horizontal direction. If a columnar or barrel-shaped longitudinally rotating member is disposed at both upper ends of the U-shape, it is effective for smoothly taking in and out the feet. (Example 5)
　挟持部をおおまかにはW字に近い構造とし、W字両側は各々が単独で縦回転するべくその各中段を底板から支持されたヒンジ部に固定された状態で、W字両下端以内はアーチ状を原形とする踏み板を底板に固定もしくはW字両側下端にヒンジ連結させた状態とすると、その踏み板は足の踏み込みにより水平方向に展ばされながらW字両側下端内幅を押し広げ、同時にW字両側上端内幅を狭めてその間に足を挟みこむ役目となる。逆に足を抜き出すときは、蓄勢された反発力により足を押し上げながら、W字両側と共に原形に戻る。足を水平方向に出し入れする着脱法と兼用可能で、W字両上端部に円柱形もしくは樽形の縦回転部材を配置すると、円滑な足の出し入れに有効である。（実施例６） The sandwiching part is roughly structured like a W-shape, and both sides of the W-shape are fixed to hinges supported from the bottom plate so that each of them can be independently rotated vertically, and the arches are within the lower ends of the W-shape. If the foot plate is shaped like a shape and fixed to the bottom plate or hinged to the lower ends of both sides of the W shape, the foot plate spreads horizontally by stepping on the foot while pushing the inner width of the lower ends of both sides of the W shape. It narrows the inner width at the upper end of both sides of the character and serves to sandwich the foot between them. On the other hand, when pulling out the foot, it will return to its original shape along with both sides of the W-shape while pushing up the foot with the accumulated repulsive force. It can also be used as a detaching method for putting in and out the foot in the horizontal direction, and if a columnar or barrel-shaped longitudinally rotating member is arranged at both upper ends of the W shape, it is effective for putting in and out the foot smoothly. (Example 6)
　挟持部をおおまかにはW字に近い構造とし、W字両下端以内は直板を原形としアーチ状にたわませた踏み板もしくは直板２枚を山成りに突合せヒンジ連結した踏み板をそれらが反転できる程度の空間を下部に確保した上でその両端部のみ底板にヒンジ固定し、W字両側は踏み板両端部付近に立ち上がるように固定すると、その踏み板は足の踏み込みにより圧縮されながら下方に沈みW字両側内幅を狭めて反転し、踏み板反転後はW字両側がその間に足を挟みこむ役目となる。逆に足を抜き出すときは、W字両側が踏み板を呼び起こし圧縮頂点後は踏み板がW字両側を初期位置に押し広げる。W字両上端部に円柱形もしくは樽形の縦回転部材を配置すると、円滑な足の出し入れに有効である。（実施例７） The sandwiching part is roughly structured like a W-shape, and within the lower ends of the W-shape, the straight plate is the original shape and the arch-shaped stepping plate or two stepping plates that are joined together in a hill-like manner can be reversed. The bottom plate is hinged to the bottom plate at both ends, and both sides of the W shape are fixed so that they stand up near both ends of the step plate. The inside width is narrowed and reversed, and after the treadle is reversed, both sides of the W-shaped part serve to sandwich the foot between them. On the other hand, when pulling out the foot, both sides of the W-shape wake up the footboard, and after the top of compression, the footboard pushes both sides of the W-shape to the initial position.
