Description

本発明は、通気性や開放性とフォーマル性の両立を図った履物に関するものである。   The present invention relates to footwear that achieves both breathability, openness and formality.

足裏は、人体で特に多くの汗腺が分布しているところであるので、温暖な地域や熱帯地方では、足の甲を覆わずに紐やバンドで足を固定する履物（以下サンダルと記す）が、古くから着用されてきた。しかし、フォーマルな場や対面の場では、サンダルはタブーとされ、足の蒸れによる不快感を我慢して革靴が着用されている。そのため、足の甲を甲被で覆った履物の長時間着用による不快感を抑制するために、種々の改良が試みられている。例えば透湿防水性の材料を履物の甲被部材として用いたり、あるいは爪先や土踏まず部のアウトソールを開口し、外気を取り入れる構造のものが知られている（特許文献１）。この他、ヒール部にエアポンプや送風装置を設け、爪先部に換気管路を介して外気を強制的に送り込むものや（特許文献２）、両端が排水孔となっている水路を先芯の肉厚部内に形成し、該水路に沿って穿設した複数の導気孔と複数の通孔とにより該水路をそれぞれ靴外及び靴内へ連通させるとともに、液体水不透過性かつ水蒸気透過性の膜を該水路への該通孔の開口部に配設し、靴内への雨水侵入防止と靴内の通気性とを確保するものがある（特許文献３の図１及び図３）。   The foot sole is where many sweat glands are distributed in the human body. In warm and tropical areas, footwear (hereinafter referred to as sandals) that secures the foot with a string or band without covering the instep Have been worn for a long time. However, in formal and face-to-face situations, sandals are taboo, and leather shoes are worn to withstand the discomfort caused by stuffy feet. For this reason, various improvements have been attempted in order to suppress discomfort caused by wearing the footwear with the instep covered with the upper for a long time. For example, there is known a structure in which a moisture-permeable and waterproof material is used as an upper member of footwear, or an outsole of a toe or arch is opened to take in outside air (Patent Document 1). In addition, an air pump or a blower device is provided in the heel part, and forcing the outside air to the toe part via a ventilation pipe (Patent Document 2), or a water path having both ends as drain holes is provided in the tip of the meat. A water-impermeable and water-vapor permeable membrane formed in the thick portion and connected to the outside of the shoe and the inside of the shoe respectively by a plurality of air guide holes and a plurality of through holes formed along the water channel Is provided at the opening of the through hole to the water channel to prevent rainwater from entering the shoe and to ensure air permeability in the shoe (FIGS. 1 and 3 of Patent Document 3).

一方で従来、履物の内側に足の固定手段に類するものを有する履物は、外反母趾など足の障害を抑制するためのものが提案されているが（特許文献４）、足の締付け具合を調整できるものはなかった。さらに履物内部の蒸れや悪臭の発生を防止するために、履物の内側に足の装着手段を設けて履物内部の通気性を向上させる試みはない。   On the other hand, the footwear having a foot fixing means on the inside of the footwear has been proposed to suppress foot injury such as hallux valgus (Patent Document 4), but the foot tightening degree can be adjusted. There was nothing. Furthermore, there is no attempt to improve the breathability inside the footwear by providing a foot mounting means inside the footwear in order to prevent the occurrence of stuffiness and bad odor inside the footwear.

特開平７−３２７７０６号公報JP 7-327706 A 特開平７−２３８０２号公報Japanese Patent Laid-Open No. 7-23802 特開２００１−３７５０３号公報JP 2001-37503 A 特開２００２−１６５６１１号公報JP 2002-165611 A

従来のサンダル以外の履物は、甲被と足の固定手段が同一であるため、歩行安定性を得るためには甲被を足に密着させることが必須であった。そのため、履物の内部は密閉状態で高湿状態になることが多く、足蒸れや悪臭などの不快な問題を発生させていた。これを改善するために靴内部と外部とをつなぐ通気孔を設けても、サンダル履きほどの通気性や開放感が得られなかった。足蒸れや悪臭などの不快感を嫌ってサイズの大きめの靴を着用すれば、足の指先に障害が発生したり、靴が脱げ易くなる等の副作用があり、歩行の安全性・安定性に支障をきたすことがあった。   Since footwear other than conventional sandals has the same instep and foot fixing means, in order to obtain walking stability, it is indispensable to bring the instep into close contact with the foot. For this reason, the interior of the footwear is often in a sealed state and in a high humidity state, causing unpleasant problems such as foot stuffiness and bad odor. In order to improve this, even if a vent hole connecting the inside and the outside of the shoe was provided, the air permeability and feeling of opening as wearing sandals could not be obtained. If you wear large shoes that dislike the feeling of discomfort such as stuffy feet or odors, there are side effects such as damage to the toes of the toes and easy removal of the shoes, which makes walking safer and more stable. There was a problem.

本発明は、上述の問題点に鑑みなされたものであり、甲被で覆われた履物であってもサンダルのような履き心地とフォーマルな外形デザイン・足の被覆機能や高い歩行安定性とを両立可能な履物を提供することを課題とする。さらに足の動作状況に応じて足の締付け状態をダイナミックに変化させて、従来の履物には無い快適な機能を有する履物を提供することを第２の課題とする。   The present invention has been made in view of the above-mentioned problems, and even if the footwear is covered with an instep, it has a comfortable feeling like a sandal, a formal outer shape design, a covering function of the foot, and high walking stability. It is an object to provide compatible footwear. Furthermore, a second problem is to provide a footwear having a comfortable function not found in conventional footwear by dynamically changing the tightening state of the foot according to the motion state of the foot.

上記課題を解決するために、本発明に係る履物の第１の特徴は、履物の甲側にあって前記履物の底に足を密着させる装着手段と、前記装着手段とは密着せずに装着手段の外側を覆う甲被とを備え、甲被に覆われて外部から直接的に足の締付け具合を調節できない前記装着手段に対し前記装着手段は足の締付け具合を調節可能とした。すなわち足の固定機能と履物の外形・被覆機能を分離した。   In order to solve the above-described problem, the first feature of the footwear according to the present invention is that the footwear is located on the back side of the footwear, and the footwear is attached to the bottom of the footwear, and the footwear is not in close contact with the footwear. And an upper that covers the outside of the means, and the attachment means can adjust the degree of tightening of the foot relative to the attachment means that is covered with the upper and cannot directly adjust the degree of tightening of the foot. That is, the foot fixing function and the footwear outer shape / covering function were separated.

この構成によれば、履物が足に密着する面積が減るので、熱や汗が放散され易くなる。さらに足と甲被との間に空間を設けることができるので、甲被材料に左右されずに蒸れた履物内部の空気が換気され易くなる。すなわち甲被材料は、通気性に関わる材質や厚み、コスト等の制約に左右されずに材料選択が可能となる。同時に、足の装着手段は、甲被７に依存せずに足の締付け具合を調節することができるので、歩行あるいは走行時でも高い安定性や安全性を得ることができる。さらに足のサイズの個人差や一日のうちで変化する足の大きさに対応して適宜、最適な足の締付け状態に調節できる。   According to this configuration, since the area where the footwear is in close contact with the foot is reduced, heat and sweat are easily dissipated. Furthermore, since a space can be provided between the foot and the upper, the air inside the footwear is easily ventilated without being influenced by the upper material. That is, it is possible to select the material of the upper material without being influenced by restrictions on the material, thickness, cost, and the like related to air permeability. At the same time, the foot mounting means can adjust the tightening degree of the foot without depending on the upper 7, so that high stability and safety can be obtained even during walking or running. Furthermore, it is possible to adjust the foot tightening state appropriately according to individual differences in foot size and the size of the foot that changes within a day.

さらに好ましい態様において、前記装着手段は、少なくとも一部に紐状もしくは帯状の形状可変部を有し、前記履物の底及び／又は前記甲被側面に少なくとも一端を固定された足の締付部材を備えるものであって、前記形状可変部を変形させて足の締付け具合を調節する。すなわち形状可変部を足に対する周囲長（内径）方向とは異なる履き口方向に変形させて周囲長を変化させるか、もしくは周囲長そのものが伸縮するようする。この構成によれば、装着手段の内径を変化させることができるので、甲被の内側であっても容易に足の締付け具合を調節することが可能となる。つまり、締付け具合を調節するために足と甲被との間に大きな空間を必要とせずに、外観的にも優れた履物を提供することができる。   In a further preferred aspect, the wearing means includes a foot fastening member having at least a part of a string-like or belt-like shape changing portion, and having at least one end fixed to the bottom of the footwear and / or the side of the upper. The shape variable portion is deformed to adjust the tightening condition of the foot. That is, the shape variable portion is deformed in the direction of the mouth different from the circumferential length (inner diameter) direction with respect to the foot to change the circumferential length, or the circumferential length itself is expanded and contracted. According to this configuration, since the inner diameter of the mounting means can be changed, it is possible to easily adjust the degree of foot tightening even inside the upper. That is, it is possible to provide footwear that is excellent in appearance without requiring a large space between the foot and the upper for adjusting the tightening degree.

さらに好ましい態様において、前記装着手段は、歩行時にほとんど変形しない足の甲の部分を覆う保形性を有する甲パッドを具備する。この構成によれば、締付部材による締付力が甲パッドを介して足に分散して加わるので、足に痛みを生じにくくなるとともに、足のホールド性が向上する。なお甲パッドは、材料の肉厚を薄くするなどして部分的に折り曲げ可能なものであってもよい。   In a further preferred aspect, the wearing means includes an instep pad having a shape retaining property that covers a part of the instep of the foot that hardly deforms during walking. According to this configuration, since the tightening force by the tightening member is distributed and applied to the foot via the upper pad, it is difficult to cause pain in the foot and the holdability of the foot is improved. The upper pad may be one that can be partially bent by reducing the thickness of the material.

さらに好ましい態様において、前記甲パッドは、前記装着手段に対して脱着可能に構成されている。この構成によれば、履物の製造過程で甲パッドを外した状態で甲被を形成することができるので、靴型を用いて製造する従来の製法が適用でき、製造が容易である   In a further preferred aspect, the upper pad is configured to be removable from the mounting means. According to this configuration, the upper can be formed with the upper pad removed in the footwear manufacturing process, so that a conventional manufacturing method using a shoe mold can be applied and manufacturing is easy.

さらに好ましい態様において、前記甲パッドには、前記形状可変部の変形量を調節し保持する調節機構が具備されている。この構成によれば、強度や信頼性を要求される調節機構が、甲被に無関係に構成できるので、従来の甲被材や製法を大幅に変更する必要がない。また調節機構は甲被で隠すことができるので、外観上の制約なく調節機構を構成することができる。   In a further preferred aspect, the upper pad is provided with an adjusting mechanism for adjusting and holding the deformation amount of the shape variable portion. According to this configuration, the adjustment mechanism that requires strength and reliability can be configured regardless of the upper, so that it is not necessary to significantly change the conventional upper material and manufacturing method. Further, since the adjusting mechanism can be hidden by the upper, the adjusting mechanism can be configured without any restriction on the appearance.

さらに好ましい態様において、前記調節機構は、前記形状可変部を前記履物の履き口方向に引き寄せる連行手段と、前記連行手段を甲パッドに係止する係止手段と、を有している。この構成によれば、適度な柔軟性を有するプラスチックや金属、木質材料及び複合材料などの保形性の材料で形成した甲パッドを調節機構の一部として利用することで、調節機構を少ない部品点数と十分な強度で構成できる。また、足と甲被の狭い空間内に調節機構を配設することが可能となる。さらに締付の調整方向が履き口に向かう足の長さ方向だけとなるので、足を踏ん張りながら片手で容易に締付け具合の調整が可能となる。   In a further preferred aspect, the adjustment mechanism includes entraining means for pulling the shape variable portion toward the footwear of the footwear, and locking means for locking the entrainment means to the upper pad. According to this configuration, the adjustment mechanism can be used with a small number of parts by using an instep pad formed of a shape-retaining material such as plastic, metal, wood material, and composite material having moderate flexibility. It can be configured with a score and sufficient strength. In addition, an adjustment mechanism can be disposed in a narrow space between the foot and the upper. Furthermore, since the tightening adjustment direction is only the length direction of the foot toward the mouth, it is possible to easily adjust the tightening condition with one hand while stepping on the foot.

さらに好ましい態様において、前記連行手段は紐状部材を含み、前記係止手段は、少なくとも前記紐状部材の特定部に特定部以外より大きな外径を有する膨出部と、前記甲パッドに設けられて爪先方向（＝反履き口方向）への前記膨出部の移動を阻止する係止部とからなる。例えば、甲パッドに形状可変部近くから履き口近くに貫通する孔を設け、この貫通孔の履き口側の開口形状を前記膨出部が通過可能な大きな孔と通過できない小さい孔とを連結した構造とする。この構成によれば、前記紐状部材を大きな孔から小さい孔に移動することで、膨出部が小さい孔によって移動を阻止されるので、形状可変部の変形状態を所望のところで保持できる。さらに前記紐状部材の履き口側の端を前記形状可変部と紐状部材との結合点に結んで環状にすれば、片手の指1本で締付調節・解除が迅速・容易にできる。   In a further preferred aspect, the entrainment means includes a string-like member, and the locking means is provided at the bulging portion having an outer diameter larger than at least the specific portion at the specific portion of the string-shaped member and the upper pad. And a locking portion that prevents the bulging portion from moving in the toe direction (= the anti-wearing mouth direction). For example, a hole penetrating from near the shape variable part to the mouth is provided in the upper pad, and a large hole through which the bulging part can pass and a small hole through which the bulging part can pass are connected to the opening shape of the through hole of the through hole. Structure. According to this configuration, by moving the string-like member from the large hole to the small hole, the bulging portion is prevented from moving by the small hole, so that the deformed state of the shape variable portion can be maintained at a desired place. Further, if the end on the side of the mouth of the string-like member is connected to the connecting point between the shape variable portion and the string-like member to make an annular shape, the tightening adjustment / release can be quickly and easily performed with one finger of one hand.

さらに好ましい態様において、前記甲パッドは、通気を可能とする複数の孔又は微細構造を有する。すなわち、保形性を有する甲パッドの全面に亘って通気や放湿を可能とする多数の孔や微細構造を形成してもよい。この構造によれば、足の甲から発散される熱や汗が、甲パッドによって放散を妨げられることが減るので、快適さが向上する。   In a further preferred embodiment, the upper pad has a plurality of holes or microstructures that allow ventilation. That is, a large number of holes and fine structures that allow ventilation and moisture release may be formed over the entire surface of the upper pad having shape retention. According to this structure, since heat and sweat emitted from the instep of the foot are prevented from being dissipated by the instep pad, comfort is improved.

さらに好ましい態様において、前記履物の少なくとも爪先部に履物内部と外部とをつなぐ通孔を設けて通気する換気構造を有する。具体的には、アウトソールや甲被に通孔を設ける。この構造によれば、汗腺が多く、最も水虫になりやすい足指部分に冷涼低湿な外気が導入され易くなる。また足と甲被との間に確実にできる隙間が煙突の役目を果たし、歩行をしていない着座時でも爪先部に外気が常に流入する自然換気が行われるので、足指部分が常に快適に保たれ、水虫や悪臭を防止することができる。   In a further preferred embodiment, the footwear has a ventilation structure that ventilates by providing a through hole that connects the inside and the outside of the footwear at least at the toe portion of the footwear. Specifically, a through hole is provided in the outsole or the upper. According to this structure, it is easy to introduce cool and low humidity outside air into the toe portion where there are many sweat glands and most likely to cause athlete's foot. In addition, the gap that can be surely made between the foot and the instep serves as a chimney, and natural ventilation is performed so that outside air always flows into the toes even when sitting without walking, so the toes are always comfortable It is kept and can prevent athlete's foot and odor.

別の態様において、前記形状可変部の一部又は全部は、電気的に形状変形が可能な高分子複合構造体である。すなわち、前記締付部材の一部又は全部を電気的に伸縮可能な高分子複合構造体で構成する。この構成によれば、締付部材自体が電気的に１秒レベルの瞬時に伸縮するので、足の締付具合の調節を人が直接行わなくても、足の動きを自動検知してダイナミックに調節したり、手元の端末などから遠隔操作で調節したりすることができる。   In another aspect, part or all of the shape variable portion is a polymer composite structure that can be electrically deformed. That is, a part or all of the tightening member is composed of a polymer composite structure that can be electrically expanded and contracted. According to this configuration, the fastening member itself electrically expands and contracts instantaneously at the level of 1 second, so even if the person does not directly adjust the foot tightening condition, the movement of the foot is automatically detected to make it dynamic. It can be adjusted or remotely controlled from a terminal at hand.

さらに好ましい態様において、前記高分子複合構造体は、少なくとも締付け時に波型状に変形して長さが縮むことで足の締め付け具合を調節する。すなわち、前記高分子複合構造体は、短冊状の高分子素子を長手方向に複数連結し、隣接素子を互い違いに逆方向に湾曲させる、あるいは各素子を同方向に電気的に湾曲させることで、素子全体の長さを伸縮させる。締付け時においては、前記高分子複合構造体と足とは、湾曲の頂点部で接することになるので、密着感・圧迫感を抑制することができる。また前記高分子複合構造体と甲被との対向関係についても同様になるので、通気空間が確保され易くなる。   In a further preferred embodiment, the polymer composite structure is deformed into a corrugated shape at least when tightened, and the length of the polymer composite structure is shortened to adjust the degree of foot tightening. That is, the polymer composite structure is formed by connecting a plurality of strip-shaped polymer elements in the longitudinal direction and alternately bending adjacent elements in the opposite direction, or by electrically bending each element in the same direction. Stretch the length of the entire device. At the time of tightening, the polymer composite structure and the foot are in contact with each other at the apex portion of the curve, so that it is possible to suppress a feeling of close contact and pressure. In addition, since the same is true for the facing relationship between the polymer composite structure and the upper, it is easy to secure a ventilation space.

別の態様において、前記履物は、着座時を含む歩行スピードの違いを足の動きから検知する検出手段を備えており、前記装着手段は該検出手段からの信号に基づき足の締付け具合を変える電子的な制御手段を具備している。前記検出手段は、足の加速度や締付帯に掛かる応力を検出し、その度合いに応じた電気的出力を出力する。前記制御手段は、前記検出手段からの出力の大きさや単位時間当たりの頻度分布から、足の動きが今どのような状態なのかを識別し、その結果に基づいて前記高分子構造体の伸縮を自動調整する。   In another aspect, the footwear includes detection means for detecting a difference in walking speed including when sitting, from movement of the foot, and the mounting means is an electronic device that changes the degree of tightening of the foot based on a signal from the detection means. The control means is provided. The detection means detects the acceleration applied to the foot and the stress applied to the fastening band, and outputs an electrical output corresponding to the degree. The control means identifies the current state of foot movement from the magnitude of the output from the detection means and the frequency distribution per unit time, and based on the result, expands and contracts the polymer structure. Adjust automatically.

この構成によれば、歩行を始めた時には足の締付け力を即座に強めて足と履物の一体感を高め、歩行の安定性を得ることができる。一方、着座して足の動きが止まった時には、足の締付け力を緩めて体温や汗の放散を促し、リラックス感を得られるようにできる。ここで述べた自動調整方法は、制御手段のソフトウェアにより様々に変更可能であることは、言うまでもない。   According to this configuration, when the user starts walking, the foot tightening force is immediately increased to enhance the sense of unity between the foot and the footwear, and the stability of walking can be obtained. On the other hand, when you stop sitting and your feet stop moving, you can relax your feet and encourage your body temperature and sweat to relax. It goes without saying that the automatic adjustment method described here can be variously changed by software of the control means.

本発明の他の態様において、履物は、履物の底と、履物の甲側にあって前記履物の底に足を密着させる装着手段と、前記装着手段の外側を覆う甲被とを備える。前記装着手段は、電気的に伸縮可能な高分子複合構造体と、前記履物に具備された操作部又は遠隔操作器からの設定情報に基づき前記高分子複合構造体に通電して足の締付け具合を電気的に調節する制御手段とを含む。これにより、装着手段による足の締付け具合を履物の外から簡単に調整することができる。   In another aspect of the present invention, the footwear includes a bottom of the footwear, an attachment means that is on the instep side of the footwear and that closely contacts the foot with the bottom of the footwear, and an upper that covers the outside of the attachment means. The mounting means includes a polymer composite structure that can be electrically expanded and contracted, and energizing the polymer composite structure based on setting information from an operation unit or a remote controller provided in the footwear, thereby tightening a foot. And a control means for electrically adjusting. As a result, the degree to which the foot is tightened by the mounting means can be easily adjusted from the outside of the footwear.

FIG. 1 is a side perspective view showing a configuration of footwear provided with foot mounting means of the present invention which is Embodiment 1 of the present invention. FIG. 2 is a plan perspective view showing the main part of the mounting means provided inside the upper 2. 3 and 4 are cross-sectional views taken along lines AB and CD in FIG. 2, respectively.

図１〜図４において、２００は履物全体を示し、履物２００は概略的に、アウトソール１（本底）と、インソール３と、甲被（アッパー）２と、足の装着手段から構成されている。足の装着手段は、締付帯５、６、３０、３１と形状可変部材８、９、１０、甲パッド７及び牽引部材１２、１３を主要構成要素とする。本発明の履物は足の固定機能と履物の外形・被覆機能とが分離されており、甲被１は足の固定機能を主体的に持たない。以下の説明では、皮革製紳士用ビジネスシューズを中心に本発明の詳細を述べるが、これに限定されるものではない。   1-4, 200 shows the whole footwear, and the footwear 200 is roughly comprised from the outsole 1 (outsole), the insole 3, the upper (upper) 2, and the mounting | wearing means of a leg | foot. Yes. The foot mounting means includes the fastening bands 5, 6, 30, 31 and the shape variable members 8, 9, 10, the upper pad 7 and the traction members 12, 13 as main components. In the footwear of the present invention, the foot fixing function and the outer shape / covering function of the footwear are separated, and the upper 1 does not have the foot fixing function. In the following description, details of the present invention will be described focusing on leather men's business shoes, but the present invention is not limited to this.

アウトソール１は、例えば革やポリウレタンなどの合成樹脂、弾力のある発泡素材で一体形成される。甲被２は、革や合成皮革、布などの材料が用いられ、甲被２の端部と締付帯５、６、３０、３１の端部がアウトソール１とインソール３と間に釣込まれて接着あるいは縫い合わされ、アウトソール１に固定されている。足の固定は、装着手段とアウトソール１と甲被２の後端部４とでなされるが、後端部４は必須のものではない。   The outsole 1 is integrally formed of a synthetic resin such as leather or polyurethane, or an elastic foam material. The upper 2 is made of a material such as leather, synthetic leather, or cloth, and the end of the upper 2 and the ends of the fastening bands 5, 6, 30, 31 are caught between the outsole 1 and the insole 3. Are bonded or sewn together and fixed to the outsole 1. The foot is fixed by the mounting means, the outsole 1 and the rear end 4 of the upper 2, but the rear end 4 is not essential.

図２に示すようにアーチ型の前締付帯５と前締付帯３０とは、形状可変部材８によって接続されている。締付帯や形状可変部材の材質は、合成繊維や革など通常ベルトや紐に使われるものを主材とするものでよい。図５は、甲パッド７の上面から見た平面図である。甲パッド７は、適度な柔軟性を有するプラスチックや金属、木質材料及び複合材料などの保形性の材料で形成される。甲パッド７は、鉤状突起１４、３７に形状可変部材８を引っ掛けて甲パッド前方部が懸架される。   As shown in FIG. 2, the arch-shaped front fastening band 5 and the front fastening band 30 are connected by a shape variable member 8. The material of the fastening band and the shape variable member may be a material mainly used for a belt or string such as synthetic fiber or leather. FIG. 5 is a plan view seen from the upper surface of the upper pad 7. The upper pad 7 is formed of a shape-retaining material such as plastic, metal, wood material, and composite material having appropriate flexibility. The upper part of the upper pad 7 is suspended by hooking the shape variable member 8 on the hook-shaped protrusions 14 and 37.

前足部と中足部の締め付け具合を調節するには、形状可変部材８における鉤状突起１４、３７の中間点部１１を牽引部材１３で履き口２４側に引くことにより行う。締め付け具合を保持するには、牽引部材１３の端部にある元々の牽引部材１３の径より大きな外径を有する複数の膨出部２２と、前記甲パッド７に設けられた前記膨出部２２の移動を阻止する係止部とを設けて牽引部材１３の移動を制限する。例えば、甲パッド７に形状可変部材８の中間点部１１の近くから履き口近くに繋がる孔１９、１８を設け、この孔のうち爪先側の孔１９の開口形状を前記膨出部が通過可能な大きな孔とし、履き口側の孔１８の開口形状を前記膨出部が通過できない小さい孔１８ａ（図５）と前記膨出部が通過できる大きな孔１８ｂ（図５）とを設け、両者の接触箇所で相互に連結した構造とする。そして、牽引部材１３の位置を保持する場合は、牽引部材１３を小さい孔１８a側に動かし、小さい孔１８aの周縁への膨出部２２の当接により膨出部２２の移動を阻止する。逆に牽引部材１３を出し入れする場合は、牽引部材１３を大きい孔１８b側に動かす。牽引部材１３は、牽引部材１２と同様に環状にしてもよく、その場合には、端を中間点部１１に戻して結わえる。   In order to adjust the tightening degree of the forefoot part and the middle foot part, the intermediate point part 11 of the hook-like protrusions 14 and 37 in the shape variable member 8 is pulled by the traction member 13 toward the wearing mouth 24 side. In order to maintain the tightening degree, a plurality of bulging portions 22 having an outer diameter larger than the diameter of the original traction member 13 at the end of the traction member 13, and the bulging portions 22 provided on the upper pad 7. The movement of the traction member 13 is limited by providing a locking portion that prevents the movement of the traction member 13. For example, the upper pad 7 is provided with holes 19 and 18 that are connected from the vicinity of the middle point portion 11 of the variable shape member 8 to the vicinity of the wearer's mouth, and the bulging portion can pass through the opening shape of the hole 19 on the toe side among these holes. A small hole 18a (FIG. 5) through which the bulging part cannot pass through the opening shape of the hole 18 on the mouth side, and a large hole 18b (FIG. 5) through which the bulging part can pass. The structure is connected to each other at the contact points. And when holding the position of the traction member 13, the traction member 13 is moved to the small hole 18a side, and the movement of the bulging part 22 is prevented by contact | abutting of the bulging part 22 to the periphery of the small hole 18a. Conversely, when the pulling member 13 is put in and out, the pulling member 13 is moved to the large hole 18b side. The traction member 13 may be annular like the traction member 12, and in that case, the end can be connected back to the intermediate point portion 11.

同様に後締付帯６と後締付帯３１とは、形状可変部材９、１０によって接続されている。甲パッド７は、鉤状突起１５、３５と１６、３６に形状可変部材９、１０をそれぞれ引っ掛けることで甲パッド後方部が懸架される。そして形状可変部材９、１０を鉤状突起１５、３５と１６、３６の中間点部３８で一つにまとめて牽引部材１２で履き口２４側に引くことにより、後足部の締め付け具合を調節する。牽引部材１２は、中間点部３８に戻るように環状に構成されているので、環状の牽引部材１２に指を掛けることで指一本で締付け具合を調整できる。   Similarly, the rear tightening band 6 and the rear tightening band 31 are connected by the shape variable members 9 and 10. The back of the upper pad 7 is suspended by hooking the variable shape members 9 and 10 on the hook-shaped protrusions 15, 35 and 16, 36, respectively. Then, the shape variable members 9 and 10 are gathered together at the midpoint portion 38 of the hook-shaped projections 15, 35 and 16 and 36, and pulled by the traction member 12 toward the wearing mouth 24, thereby adjusting the tightening degree of the rear foot portion. To do. Since the pulling member 12 is formed in an annular shape so as to return to the intermediate point portion 38, the tightening degree can be adjusted with one finger by hooking the finger on the annular pulling member 12.

牽引部材１２の位置を保持する場合は、牽引部材１２を孔１８と同様に小孔１７ａと大孔１７ｂとを両者の接触箇所で連結した孔１７の小さい孔側に動かし、孔１７で膨出部２１の移動を阻止する。逆に牽引部材１２を出し入れする場合は、牽引部材１２を大きい孔側に動かす。   When the position of the pulling member 12 is maintained, the pulling member 12 is moved to the small hole side of the hole 17 in which the small hole 17a and the large hole 17b are connected at the contact point of the both in the same manner as the hole 18 and bulges in the hole 17 The movement of the part 21 is prevented. Conversely, when the traction member 12 is taken in and out, the traction member 12 is moved to the larger hole side.

なお前記膨出部は、硬質のプラスチックや金属、ゴムなどを用いて形成されるが、牽引部材と一体形成されたものや、別個に形成され牽引部材に取り付けられたもの、あるいはそれらを組み合わせたものが考えられる。本発明ではいずれの方法で形成されたものでもよいが、次に例示する牽引部材と一体形成されたものが好適である。   The bulging part is formed using hard plastic, metal, rubber or the like, but is formed integrally with the traction member, separately formed and attached to the traction member, or a combination thereof. Things can be considered. In the present invention, it may be formed by any method, but is preferably formed integrally with a pulling member exemplified below.

第１の例は、１１ナイロンやポリプロピレンなどの適度な柔軟性と引っ張り強度を有する樹脂を用いて、紐と膨出部とを一体成型したものである。膨出部は予め所定の位置に複数形成されている。この場合、図２の係合部３８における紐端部の留め具も一体形成でき、コスト面で有利である。   In the first example, a string and a bulging portion are integrally molded using a resin having appropriate flexibility and tensile strength such as 11 nylon and polypropylene. A plurality of bulges are formed in advance at predetermined positions. In this case, the fastener at the end of the string in the engaging portion 38 in FIG. 2 can be integrally formed, which is advantageous in terms of cost.

第２の例は、ゴム質の芯材の外周を伸縮し難い糸で編んで覆った構造の伸縮可能なもので、編み方を部分的に変えることで膨出部を形成できるようにしたものである。この複合ゴム紐は、引っ張った力に応じて膨出部が縮小し、放置すれば膨出部が形成される。本発明の牽引部材として芯材に適度な弾力を有するゴム材を使用すれば、足の動きや足の大きさの変化に応じた締付け具合の微妙な調整が自然に行われることになり、履き心地が向上する。   The second example is a stretchable structure in which the outer periphery of a rubber core is knitted and covered with a thread that is difficult to stretch, and the bulging part can be formed by partially changing the knitting method It is. In this composite rubber cord, the bulging portion shrinks according to the pulled force, and the bulging portion is formed if left untreated. If a rubber material having an appropriate elasticity is used for the core member as the pulling member of the present invention, the subtle adjustment of the tightening according to the movement of the foot and the change in the size of the foot will be naturally performed. Comfort is improved.

上記一体形成以外の例としては、（第３の例）紐に対して挟み込み構造をもつ金属珠をかしめて紐の所定部位に固定したものや、（第４の例）紐の所定部位２ヶ所に固定膨出部を設け、中心に貫通穴を有して、貫通穴に紐１３を通して移動可能な複数の球状体を前記固定膨出部間に数珠状に設けたものが例示される。牽引部材は、任意の球状体間で小孔に移動できるように前記前記固定膨出部間には、算盤のようにすべての球状体が移動可能な紐の長さを有する。この場合の紐は、ポリエステル、ナイロン、革などの伸縮し難い材質であることが好ましい。   Examples other than the above-described integral formation include (third example) a metal bead having a sandwiched structure with respect to a string and fixed to a predetermined part of the string, and (fourth example) two predetermined parts of the string. A fixed bulge portion is provided on the center, and a through hole is provided at the center, and a plurality of spherical bodies that can be moved through the string 13 in the through hole are provided in a rosary shape between the fixed bulge portions. The pulling member has a length of a string in which all the spherical bodies can move like the abacus between the fixed bulging portions so that the pulling member can move to a small hole between arbitrary spherical bodies. The string in this case is preferably made of a material that is difficult to expand and contract, such as polyester, nylon, and leather.

図３、図４は、それぞれ図２のＡ−Ｂ線及びＣ−Ｄ線に沿って横断した横断面図である。図３において甲パッド７の上部には空洞部５３、５４が設けられ、また、図４において甲パッド７の上部には空洞部５５が設けられている。図５に示すように、空洞部５３の履き口部２４側及び反履き口部２４側の端はそれぞれ孔１７，２０となっている。空洞部５４，５５は相互に連通し、空洞部５４の履き口部２４側の端は孔１８となり、空洞部５５の反履き口部２４側の端は孔１９となっている。空洞部５３、５４が甲パッドの頂部変曲部分にあることで、甲パッドの強度が高められ、甲パッド７をより薄肉軽量化することができる。   3 and 4 are cross-sectional views taken along lines AB and CD in FIG. 2, respectively. In FIG. 3, cavities 53 and 54 are provided in the upper part of the upper pad 7, and in FIG. 4, a cavity part 55 is provided in the upper part of the upper pad 7. As shown in FIG. 5, the ends of the cavity 53 on the side of the wearing mouth 24 and the side of the anti-wearing mouth 24 are holes 17 and 20, respectively. The cavities 54, 55 communicate with each other, the end of the cavity 54 on the side of the mouth 24 is a hole 18, and the end of the cavity 55 on the side of the anti-wear 24 is a hole 19. Since the hollow portions 53 and 54 are located at the top inflection portion of the upper pad, the strength of the upper pad can be increased and the upper pad 7 can be made thinner and lighter.

また空洞部５３、５４を形成する甲パッド７の膨らみは、甲被２と甲パッド７の間にある空間５２を確保するための支えの役割を担う。空間５２は、履物２００内の足首より前方の足部分の上面と甲被２の内面との間に形成され（図３及び図４）、履物２００内の爪先部２５の空間部分（図１）を履き口部２４へ連通させて、履物内部の高湿な空気を履き口部２４へ導く排出経路となるとともに、足と甲被２とを接触させ難くする緩衝空間となる。前述の特許文献４（特開２００２−１６５６１１号公報）の履物は、履物内部における爪先部空間を広げて、甲被の内面と足の爪先との間の空間について示唆するものの、足を履物内へ入れた状態で爪先から足首までの足範囲の空間、すなわち爪先部の高湿な空気を履き口部へ導く排出経路を形成することは開示していない。   Further, the swelling of the upper pad 7 that forms the hollow portions 53 and 54 serves as a support for securing the space 52 between the upper 2 and the upper pad 7. The space 52 is formed between the upper surface of the foot portion ahead of the ankle in the footwear 200 and the inner surface of the upper 2 (FIGS. 3 and 4), and the space portion of the toe portion 25 in the footwear 200 (FIG. 1). Is connected to the foot opening portion 24 to provide a discharge path for guiding high-humidity air inside the footwear to the foot opening portion 24, and a buffer space that makes it difficult for the foot and the instep 2 to come into contact with each other. Although the footwear of the above-mentioned patent document 4 (Unexamined-Japanese-Patent No. 2002-165611) expands the toe part space inside footwear and suggests about the space between the inner surface of the upper and the toe of the foot, It is not disclosed that a space in the foot range from the toes to the ankles, that is, a discharge path that guides high-humidity air in the toes to the mouth while being inserted.

空洞部５３、５４には、それぞれ牽引部材１２、１３が通っている。牽引部材１２は、甲被２と甲被２の裏側に取り付けられた懸架帯５１の間の空間を通って中間点部３８につながっている。これにより甲パッド７は、甲被２に吊り下げられた構造となるため、履物を履く際に甲パッド７が足先に引っ掛からないようにできる。   The traction members 12 and 13 pass through the cavities 53 and 54, respectively. The traction member 12 is connected to the intermediate point portion 38 through a space between the upper 2 and the suspension band 51 attached to the back side of the upper 2. As a result, the upper pad 7 has a structure suspended from the upper 2, so that the upper pad 7 can be prevented from being caught by the toes when the footwear is worn.

さらに甲パッド７の足に接する内側の部分は、通気性がよく体圧分散効果の高い編織布やスポンジ材を取り付けて、履き心地をよくしてもよい。また甲パッドの全面に亘って通気や放湿を可能とする多数の孔や微細構造を形成してもよい。このような構造にすることで、足の甲から発散される熱や汗が、甲パッドを透過して空間５２に放散されるので、快適さが向上するとともに足の甲が湿った甲パッドで擦れて痛むことを防止できる。   Further, the inner portion of the upper pad 7 that is in contact with the foot may be attached with a knitted fabric or sponge material having good air permeability and high body pressure dispersion effect to improve the comfort. Further, a large number of holes and microstructures that allow ventilation and moisture release may be formed over the entire surface of the upper pad. With such a structure, heat and sweat emitted from the instep of the foot are transmitted through the instep pad and dissipated into the space 52, so comfort is improved and the instep pad is moist. It can prevent rubbing and aching.

さらに履物の爪先部２５に外部に繋がる換気口を設けておけば、履き口２４は前記換気口より高い位置になるので、煙突効果により前記換気口には負圧が働き、空気の自然換気が行われる。さらに歩行時には、足の動きによる爪先部２５の空間容積が変化するふいご作用により、前述の空間５２を介した換気の他に、前記換気口を経由した積極的な吸排気が行われ易くなる。これにより、履物内部には常に新鮮な外気が導入されるようになるので、蒸れによる履物内部の不快感が大幅に軽減されることになる。   Furthermore, if a ventilation port connected to the outside is provided in the toe portion 25 of the footwear, the foot opening 24 is positioned higher than the ventilation port, so that a negative pressure acts on the ventilation port due to the chimney effect, and natural ventilation of air is performed. Done. Further, when walking, the bellows action that changes the spatial volume of the toe portion 25 due to the movement of the foot makes it easy to perform positive intake and exhaust through the ventilation port in addition to the ventilation through the space 52 described above. . As a result, fresh outside air is always introduced into the footwear, so that discomfort inside the footwear due to stuffiness is greatly reduced.

図４では、締付帯５、６、３０、３１の端部がアウトソール１とインソール３ならびに中底５０と間に釣込まれて接着あるいは縫い合わされ、アウトソール１に固定されている様子が示されている。これにより、牽引部材１２、１３を履き口２４側に引くことで締付帯の内径が縮小することになり、甲パッド７がアウトソール側及び後端部４側に引き付けられて、履物に足が固定される。   In FIG. 4, the end portions of the fastening bands 5, 6, 30, and 31 are caught between the outsole 1, the insole 3, and the midsole 50 and bonded or sewn, and fixed to the outsole 1. Has been. Thereby, the inner diameter of the tightening band is reduced by pulling the towing members 12 and 13 toward the wearing mouth 24 side, the upper pad 7 is attracted to the outsole side and the rear end 4 side, and the foot is placed on the footwear. Fixed.

なお図５に示す甲パッド７は、金型を用いてプラスチックや軽量金属、複合材料などの軽量で剛性のある材料を一体成型して作られる。このため、一体成形時に実施形態３に説明する履物に搭載する電子装置や部品等を実装する構造を作り込むことが容易にできる。   The upper pad 7 shown in FIG. 5 is made by integrally molding a light and rigid material such as plastic, light metal, and composite material using a mold. For this reason, the structure which mounts the electronic device, components, etc. which are mounted in the footwear demonstrated in Embodiment 3 at the time of integral molding can be made easily.

［実施形態２］
図６は、本発明の実施形態２である足の装着手段を備えた履物の構成を示す平面透視図である。図７は、前足部と中足部の締め付け具合を調節する調節冶具を示す図である。図８は、後足部の締め付け具合を調節するスライダー型調節部を示す断面図である。実施形態２は、実施形態１に対し形状可変部の変形量を調節し保持する調節手段が異なるものであり、共通部分の説明は省略する。 [Embodiment 2]
FIG. 6 is a plan perspective view showing the configuration of footwear provided with foot mounting means according to the second embodiment of the present invention. FIG. 7 is a view showing an adjusting jig for adjusting the tightening degree of the forefoot portion and the middle foot portion. FIG. 8 is a cross-sectional view showing a slider-type adjusting unit that adjusts the tightening degree of the rear foot. The second embodiment is different from the first embodiment in adjusting means for adjusting and holding the deformation amount of the shape variable portion, and the description of the common parts is omitted.

図６、図８において、甲パッド７には、魚骨状のスライダー溝が甲パッド７の上面に刻設されている。該スライダー溝は、図８に示すように、前後方向へ延びる倒立Ｔ字型横断面を有する１つの中心溝９４と、中心溝９４に沿って一定間隔の複数の箇所において中心溝９４から左右へ張り出す複数の枝溝９７とを有している。これに対し、スライダー９０は、図８（ｃ）に示すように、中心溝９４の横断面輪郭に一致する横断面の倒立Ｔ字型突起９３を複数、備えている。スライダー９０は、その複数の突起９３を中心溝９４に嵌入されて、中心溝９４の案内により前後方向へ摺動する。   6 and 8, the upper pad 7 has a fish-bone shaped slider groove formed on the upper surface of the upper pad 7. As shown in FIG. 8, the slider groove includes one central groove 94 having an inverted T-shaped cross section extending in the front-rear direction, and left and right from the central groove 94 at a plurality of locations at regular intervals along the central groove 94. A plurality of branch grooves 97 projecting out. On the other hand, as shown in FIG. 8C, the slider 90 includes a plurality of inverted T-shaped protrusions 93 having a cross section that matches the cross section contour of the central groove 94. The slider 90 has a plurality of protrusions 93 inserted into the center groove 94 and slides in the front-rear direction by the guide of the center groove 94.

図８（a）、（ｂ）は、それぞれ図６のスライダー型調節部をＥ−Ｆ線、Ｇ−Ｈ線で切断した縦断面図、横断面図を示す。図８（ｃ）、（ｄ）は、それぞれ甲パッド本体側から見たスライダー９０の斜視図、Ｅ−Ｆ線の切断面から見た枝溝９７と中心溝９４を示す斜視図である。スライダー９０は、中心溝９４に沿って移動するが、倒立Ｔ字型突起９３は先端の断面形状が大きくなっているため、スライダー溝から外れ難くなっている。スライダー９０は、倒立Ｔ字型突起９３と枝溝９７の位置が合ったとき、枝溝９７に沿って左又は右へ移動し図８（a）のように枝溝９７と嵌合して、前後方向位置を固定される。   FIGS. 8A and 8B are a longitudinal sectional view and a transverse sectional view, respectively, obtained by cutting the slider-type adjusting unit of FIG. 6 along the lines EF and GH. FIGS. 8C and 8D are a perspective view of the slider 90 as seen from the side of the upper pad body, and a perspective view showing the branch groove 97 and the central groove 94 as seen from the cut surface of the E-F line. The slider 90 moves along the central groove 94, but the inverted T-shaped projection 93 has a large cross-sectional shape at the tip, and is difficult to come off from the slider groove. When the inverted T-shaped protrusion 93 and the branch groove 97 are aligned, the slider 90 moves to the left or right along the branch groove 97 and fits with the branch groove 97 as shown in FIG. The position in the front-rear direction is fixed.

スライダー９０には、形状可変部材９、１０の中間部を一緒に連行するために通す連行溝９１、９２が設けられている。スライダー９０の上部には、スライダー９０を片手で操作し易くするための引き革９６が設けられている。引き革９６は、スライダー９０と丈夫な糸９８で縫い止めされている。足の締付け具合を調節するには、履き口２４に出ている引き革９６の端部を指先で摘んで引き出す。丁度よい締付け位置に来たら、引き革９６を左又は右に引き、スライダー９０の倒立Ｔ字型突起９３の位置を枝溝９７に一致させてからスライダー９０を枝溝９７に移動させることで、スライダー位置を保持させることができる。枝溝９７及び倒立Ｔ字型突起９３は、スライダー９０の枝溝９７への出し入れがスムーズに行えるように中足部方向に円弧を描くように形成されていてもよい。 The slider 90 is provided with entraining grooves 91 and 92 through which intermediate portions of the shape variable members 9 and 10 are entrained together. An upper portion of the slider 90 is provided with a pulling leather 96 for facilitating the operation of the slider 90 with one hand. The pulling leather 96 is sewn with a slider 90 and a strong thread 98. In order to adjust the tightening degree of the foot, the end of the pulling leather 96 that is exposed to the wear mouth 24 is grasped with a fingertip and pulled out. When the right tightening position is reached, pull the pulling leather 96 left or right, align the position of the inverted T-shaped projection 93 of the slider 90 with the branch groove 97, and then move the slider 90 to the branch groove 97. The slider position can be held. The branch groove 97 and the inverted T-shaped protrusion 93 may be formed so as to draw an arc in the middle foot portion so that the slider 90 can be smoothly inserted into and removed from the branch groove 97.

図７（a）に示すＥ字型の締付け調節冶具８０は、実施形態１における前足部と中足部の締め付け具合を調節する牽引部材１３に関係する構成要素に代わるものである。前足部と中足部の締め付け具合は、履物を最初に履き始めるときに調整すれば、その後の調整変更はほとんど必要ない。したがって形状可変部８の長さを調節するためには、図７（a）に示す爪８１の間隔Ｗ１とＷ２と合わせた長さ（通常はＷ１＝Ｗ２）が異なる複数の締付け調節冶具８０を用意しておき、履物の使用者に合った冶具を選び装着すればよい。締付け具合の調節の仕方は、図７（ｂ）に示すように形状可変部材８を鉤状突起１４と３７との間で締付け調節冶具８０を絡ませて調節する。この時、形状可変部８の左右方向重複長さが中央の爪８１の幅及びＷ２により変化するので、締付け調節冶具８０を交換することにより形状可変部８の締め付け具合を調整することができる。   The E-shaped tightening adjustment jig 80 shown in FIG. 7A replaces the constituent elements related to the traction member 13 for adjusting the tightening degree of the front foot portion and the middle foot portion in the first embodiment. If the degree of tightening of the forefoot part and the middle foot part is adjusted when the footwear is first worn, little adjustment is required after that. Therefore, in order to adjust the length of the shape variable portion 8, a plurality of tightening adjustment jigs 80 having different lengths (usually W1 = W2) combined with the intervals W1 and W2 of the claws 81 shown in FIG. Prepare and choose a jig that suits the user of the footwear. As shown in FIG. 7B, the method of adjusting the tightening degree is adjusted by interlacing the tightening adjusting jig 80 between the hook-shaped protrusions 14 and 37 of the shape variable member 8. At this time, since the overlapping length in the left-right direction of the shape variable portion 8 varies depending on the width of the central claw 81 and W2, the tightening degree of the shape variable portion 8 can be adjusted by replacing the tightening adjustment jig 80.

なお、締付け調節冶具８０は、形状可変部材８と甲パッド７に挟まれて、外れることはない。また、図７に示す締付け調節冶具８０は、実施形態１においても適用できることは言うまでもない。   The tightening adjustment jig 80 is sandwiched between the shape variable member 8 and the upper pad 7 and never comes off. Needless to say, the tightening adjustment jig 80 shown in FIG. 7 can also be applied to the first embodiment.

［実施形態３］
図９は、本発明の実施形態３である形状可変部の一部又は全部を電気的に伸縮可能な高分子複合構造体（電気変形素子）とした履物の構成を示す平面透視図である。第１及び第２の実施形態では、物理的な力を用いて連行手段（紐あるいはスライダ―）と該連行手段のユーザー操作部を履き口部に配設して、ユーザーが該操作部を操作して、ユーザーが直接調整できない形状可変部の締付量を調整する。同様に、本発明の実施形態３では、電子的手段である導線１３２と制御手段１３０及びユーザー操作部１３５を履き口部に配設して、ユーザーが該操作部を操作して、ユーザーが直接調整できない形状可変部の高分子複合構造体を通電伸縮させることによって締付量を調整する。ユーザー操作部１３５は、ボタンスイッチが例示される。制御手段１３０は、ユーザー操作部１３５からの信号を受けて、内蔵されたソフトウェアでデジタル制御された電気出力を導線１３２を経由して高分子複合構造体に印加する。 [Embodiment 3]
FIG. 9 is a perspective plan view showing a configuration of footwear in which a part or all of the shape variable portion according to the third embodiment of the present invention is a polymer composite structure (electric deformation element) that can be electrically expanded and contracted. In the first and second embodiments, the entraining means (string or slider) and the user operation part of the entrainment means are arranged in the wearing mouth part using physical force, and the user operates the operation part. Then, the tightening amount of the shape variable portion that cannot be directly adjusted by the user is adjusted. Similarly, in Embodiment 3 of the present invention, the lead wire 132, which is an electronic means, the control means 130, and the user operation unit 135 are arranged in the mouth portion, and the user operates the operation unit so that the user directly The tightening amount is adjusted by energizing and contracting the polymer composite structure of the variable shape portion that cannot be adjusted. The user operation unit 135 is exemplified by a button switch. The control unit 130 receives a signal from the user operation unit 135 and applies an electrical output digitally controlled by built-in software to the polymer composite structure via the conducting wire 132.

本発明の実施形態３では、ユーザー操作部１３５の機能拡張が容易であり、ユーザー操作部１３５の補助手段として検出手段１３４や遠隔操作器１４０を具備していてもよい。
検出手段１３４としては、足の加速度を検出する加速度センサが好適である。また前記高分子複合構造体には、外的応力に応じて電圧を発生するものがある。該高分子複合構造体は、締付帯に用いれば歩行時に足から締付帯に加わる力に応じた電圧を発生するので、歩行状態を識別するための検出手段として兼用することができる。 In the third embodiment of the present invention, it is easy to expand the function of the user operation unit 135, and the detection unit 134 and the remote controller 140 may be provided as auxiliary units for the user operation unit 135.
As the detection means 134, an acceleration sensor that detects the acceleration of the foot is suitable. Some of the polymer composite structures generate voltage in response to external stress. Since the polymer composite structure generates a voltage corresponding to the force applied to the tightening band from the foot during walking when used in the tightening band, it can also be used as a detection means for identifying the walking state.

この構成によれば、実施形態１、２では得られない効果を得ることができる。すなわち、足の締付具合の調節をユーザーが行なう他に、着座時を含めた歩行スピードの違いを足の動きから検知してダイナミックに締付具合を自動調節したり、手元の遠隔操作器１４０から制御手段１３０に無線や人体通信を用いて制御情報を送ることにより締付具合を調節したりすることが可能となる。   According to this configuration, an effect that cannot be obtained in the first and second embodiments can be obtained. That is, in addition to the user adjusting the degree of tightening of the foot, a difference in walking speed including when sitting is detected from the movement of the foot to automatically adjust the degree of tightening dynamically, or the remote controller 140 at hand. Therefore, it is possible to adjust the tightening condition by sending control information to the control means 130 by radio or human body communication.

高分子複合構造体とは、ポリピロール、ポリアニリン、アクリルエステル化合物などの導電性高分子に見られる電気化学的な酸化還元などによって伸縮あるいは変形するものをいう。近年、電気的エネルギ−を運動や変形に変換する場合に変換部の体積をほとんど必要としないエレクトロアクティブアクチュエータが開発されている。例えば誘電性エラストマやエレクトロアクティブポリマーを用いたものがある（特開２００５−１４９８９４号公報）。   The polymer composite structure refers to a material that expands or contracts due to electrochemical redox or the like found in conductive polymers such as polypyrrole, polyaniline, and acrylic ester compounds. In recent years, electroactive actuators have been developed that require almost no volume of the conversion portion when converting electrical energy into motion or deformation. For example, a dielectric elastomer or an electroactive polymer is used (Japanese Patent Laid-Open No. 2005-149894).

エレクトロアクティブポリマーの中でも、イオン伝導性アクチュエータ並びに導電性高分子アクチュエータは、高分子と金属電極を積層した柔軟なアクチュエータ素子であり、２〜５Ｖ程度の低電圧で素早く屈曲や伸縮が可能であるとともに、発生力が大きく耐久性があり、かつ軽量で形状成形の自由度が高いので、本発明の形状可変部材や締付部材として好適である。さらに高分子複合構造体において、常温溶融塩を含有させた（ゲル状）固体電解質を用いてドライ化させたものや、電極に炭素微粒子やカーボンナノチューブを混ぜた高分子電極に金属電極で裏打ちして低抵抗化したものがより好ましい。   Among electroactive polymers, ion conductive actuators and conductive polymer actuators are flexible actuator elements in which polymers and metal electrodes are laminated, and can be bent and stretched quickly at a low voltage of about 2 to 5 V. Since the generated force is large and durable, and it is lightweight and has a high degree of freedom in shape forming, it is suitable as a shape-variable member or a fastening member of the present invention. In addition, polymer composite structures that have been dried using a solid electrolyte containing a normal temperature molten salt (gel-like) or a polymer electrode in which carbon fine particles or carbon nanotubes are mixed are backed with a metal electrode. It is more preferable that the resistance is lowered.

図１１は、本発明における高分子複合構造体の構造例を示す図である。図１１(ａ)は、シート状導電性高分子６０を電極６１と対向電極６２とで狭持したものを一つの素子とし、シート状導電性高分子の長手方向に複数の素子を連続してつなげた高分子複合構造体を示す。図１１（ｂ）は、図(a)に対し電極が交互に接続されるようにつなげて電圧を印加した場合の湾曲した高分子複合構造体を示す。電極に電圧を印加すると、各素子は交互に逆方向に湾曲するので、印加電圧に応じて高分子複合構造体の長さが縮む。また電圧印加を止めても形状は保持される。逆電圧を印加すれば、元に戻る。   FIG. 11 is a diagram showing a structural example of a polymer composite structure in the present invention. FIG. 11A shows a sheet-shaped conductive polymer 60 sandwiched between an electrode 61 and a counter electrode 62 as one element, and a plurality of elements are continuously arranged in the longitudinal direction of the sheet-shaped conductive polymer. The connected polymer composite structure is shown. FIG. 11B shows a curved polymer composite structure when a voltage is applied by connecting the electrodes so as to be alternately connected to FIG. When a voltage is applied to the electrodes, each element is alternately bent in the opposite direction, so that the length of the polymer composite structure is reduced according to the applied voltage. The shape is maintained even when the voltage application is stopped. If reverse voltage is applied, it will return.

図１１（ｃ）は、シート状導電性高分子の同一面にある電極間を接続し、各素子に同極性の電圧を印加した場合を示す。本発明の履物に適用する場合は、電極の印加方法や電極形状は、履物の適用する場所に応じて適宜（ｂ）、（ｃ）を組み合わせたり、変形してよい。締付け時においては、前記高分子複合構造体と足とは、湾曲の頂点部で接することになるので、密着感・圧迫感を抑制することができる。また前記高分子複合構造体と甲被との対向部についても同様になるので、通気空間が確保され易くなる。また特に高分子複合構造体自体が伸縮する場合は、足との接触面積の少ないメッシュ状あるいは波型状の表面を有するソフトカバー材で高分子複合構造体を覆うことが好ましい。   FIG.11 (c) shows the case where the electrodes in the same surface of a sheet-like conductive polymer are connected and the voltage of the same polarity is applied to each element. When applied to the footwear of the present invention, the application method and the electrode shape of the electrode may be appropriately combined or modified according to the place where the footwear is applied. At the time of tightening, the polymer composite structure and the foot are in contact with each other at the apex portion of the curve, so that it is possible to suppress a feeling of close contact and pressure. In addition, since the same applies to the facing portion between the polymer composite structure and the upper, it is easy to secure a ventilation space. In particular, when the polymer composite structure itself expands and contracts, it is preferable to cover the polymer composite structure with a soft cover material having a mesh-like or corrugated surface with a small contact area with the foot.

図９に示すように実施形態３では、実施形態１、２で示した形状可変部材８、９、１０、３２、３３、３４と締付帯５、６、３０、３１の代わりに電気的に伸縮可能な高分子複合構造体１２２、１２３が締付部材となる。甲パッド１２８は、甲パッド１２８に設けられた対向する鉤状突起１２４、１２５並びに１２６、１２７によって高分子複合構造体１２２、１２３に脱着および摺動可能な状態で取り付けられる。さらに甲パッド１２８は、実施形態１と同様に甲被２に付けられた懸架帯で吊り下げられるようにしてもよい。高分子複合構造体１２２、１２３は、すべての部位が同率で伸縮する必要はなく、甲パッド１２８上にある部分を最も高い伸縮率とすることが好ましい。伸縮率の調整は、高分子複合構造体の各素子の大きさを変えたり、印加電圧を変えることで実現される。   As shown in FIG. 9, in the third embodiment, the shape variable members 8, 9, 10, 32, 33, and 34 shown in the first and second embodiments and the fastening bands 5, 6, 30, and 31 are electrically expanded and contracted. Possible polymer composite structures 122 and 123 serve as fastening members. The upper pad 128 is attached to the polymer composite structures 122 and 123 in a detachable and slidable manner by opposing hook-shaped protrusions 124, 125 and 126, 127 provided on the upper pad 128. Further, the upper pad 128 may be suspended by a suspension band attached to the upper 2 as in the first embodiment. In the polymer composite structures 122 and 123, it is not necessary that all the parts expand and contract at the same rate, and it is preferable that the portion on the upper pad 128 has the highest expansion and contraction rate. The expansion / contraction rate can be adjusted by changing the size of each element of the polymer composite structure or changing the applied voltage.

図９、図１０において、高分子複合構造体１２２、１２３は、薄型の電池１２３を電源として制御手段１３０からの制御電圧を導線１３２、１３３及び図示してないがコネクタを介して甲パッド１２８と高分子複合構造体１２２、１２３が接続されることで湾曲もしくは伸縮し、足の締付け具合を変える。電池１２３は、ボタン型一次電池やペーパー電池が薄く軽量で実装上好適であるが、他の形式の一次電池や二次電池、燃料電池やペルチェ素子等を利用した発電装置と蓄電装置を組み合わせたものであってもよい。制御手段１３０は、足の動きを検出する検出手段１３４からの信号に基づき歩行状態や着座時を識別して、足の締付け具合をダイナミックに自動調整する。   9 and 10, the polymer composite structures 122 and 123 are configured such that the control voltage from the control means 130 is supplied from the thin battery 123 to the power supply wires 132 and 133 and the upper pad 128 via a connector (not shown). When the polymer composite structures 122 and 123 are connected, they are bent or stretched to change the degree of foot tightening. The battery 123 is a button-type primary battery or paper battery that is thin and lightweight, and is suitable for mounting. However, other types of primary batteries and secondary batteries, fuel cells, Peltier elements, and other power generators and power storage devices are combined. It may be a thing. The control means 130 identifies the walking state and the sitting time based on the signal from the detection means 134 that detects the movement of the foot, and dynamically adjusts the degree of tightening of the foot dynamically.

また、制御手段１３０は、遠隔操作器１４０から無線又は人体通信を用いて、高分子複合構造体制御の基本設定情報や足の締付け具合の手動操作情報を受信して内蔵の（不揮発性）メモリに記憶し、高分子複合構造体１２２、１２３を制御する。通信では、靴紐１４１や甲パッド１２８にアンテナ線を埋め込んでもよい。これによって、乗り物や大ホールなどの狭い座席や会議の席などで、履物に指を掛けることなく足の締付け具合を遠隔調節することができるようになる。また、従来ブーツのような足の固定が十分できない履物においても、ブーツを履いたままで足の締付け具合を遠隔調節できるようになり、歩行の安定性を向上できる。 In addition, the control means 130 receives basic setting information for controlling the polymer composite structure and manual operation information for how to tighten the foot from the remote controller 140 using wireless or human body communication, and has a built-in (non-volatile) memory. And the polymer composite structures 122 and 123 are controlled. In communication, an antenna line may be embedded in the shoelace 141 or the instep pad 128. This makes it possible to remotely adjust the tightness of the foot without placing a finger on the footwear in a narrow seat such as a vehicle or a large hall or a conference seat. In addition, even in footwear that cannot sufficiently secure the foot, such as conventional boots, it is possible to remotely adjust the degree of tightening of the foot while wearing the boot, thereby improving walking stability.

なお制御手段１３０や検出手段１３４、電池１２９などの耐湿性や信頼性が要求される電子部品は、プラスチックや金属で一体形成された甲パッド１２８で保護されるように実装されることが好ましい。すなわち甲パッド１２８に電子部品の格納スペースや配線構造を設け、電子部品が履物の使用条件に影響を受け難いようにする。さらに甲パッド１２８と電子部品とを一体にしたモジュールにすれば、履物本体とは別工程で製造でき、生産性に優れたものとなる。   It should be noted that electronic components such as the control means 130, the detection means 134, and the battery 129 that require moisture resistance and reliability are preferably mounted so as to be protected by an upper pad 128 that is integrally formed of plastic or metal. That is, the storage space and wiring structure for the electronic parts are provided in the upper pad 128 so that the electronic parts are not easily affected by the use conditions of the footwear. Further, if the upper pad 128 and the electronic component are integrated into a module, the module can be manufactured in a separate process from the footwear main body, and the productivity is excellent.

以上、本発明の甲被を備えた履物の内部に足の締付け具合が調節可能な足の装着手段を備えた履物の実施形態に基づいて説明したが、本発明はこれら実施形態に限定されず種々の変形、組み合わせが可能である。例えば、装着手段における締付帯の本数や形状は、履物の用途やデザインに合わせて適宜変更してもよい。また締付帯と形状可変部とは、連続した材料を用いて一体形成されたものであってもよい。連行手段を係止する手段は、両手で操作する公知の係止手段を用いてもよい。   As mentioned above, although it demonstrated based on embodiment of the footwear provided with the mounting | wearing means of the foot which can adjust the tightening degree of the foot inside the footwear provided with the upper of the present invention, the present invention is not limited to these embodiments. Various modifications and combinations are possible. For example, the number and shape of the fastening bands in the wearing means may be changed as appropriate according to the use and design of the footwear. The fastening band and the shape variable portion may be integrally formed using a continuous material. As a means for locking the entrainment means, a known locking means operated with both hands may be used.

さらに別の変形例として、本発明の実施形態１〜３では、締付帯の端部がアウトソール１とインソール３と間に釣込まれて接着あるいは縫い合わされ、アウトソール１に固定されている例を示したが、甲被２の内側側面部に締付帯の端部が固定されていてもよい。すなわち、履物内部に設けられた装着手段の締付け具合が調節できること、さらに甲被と装着手段との間に履物内部の高湿な空気を排出する空間を確保できれば、どのように変形してもよい。   As yet another modification, in Embodiments 1 to 3 of the present invention, the end portion of the fastening band is caught between the outsole 1 and the insole 3 and bonded or sewn, and fixed to the outsole 1. However, the end of the fastening band may be fixed to the inner side surface of the upper 2. That is, as long as the tightening degree of the wearing means provided in the footwear can be adjusted, and a space for exhausting the high-humidity air inside the footwear can be secured between the upper and the wearing means, any deformation may be made. .

さらにマイクロエレクトロニクス技術を用いて電子的な制御を知能化することにより、よりきめ細かな装着制御が可能になる。また知能制御部を共用して装着制御以外の機能を装備することも容易になる。図９に示す甲パッドに電子装置を搭載する本発明の実装方法は、履物に各種の電子装置を実装して様々な有用な機能や効果を実現する場合に応用可能である。例えば無線通信機能や表示機能、発電・蓄電機能、健康管理・増進機能などが挙げられる。   Furthermore, by making electronic control intelligent using microelectronic technology, more precise mounting control becomes possible. In addition, it becomes easy to equip functions other than mounting control by sharing the intelligent control unit. The mounting method of the present invention in which the electronic device is mounted on the upper pad shown in FIG. 9 is applicable when various electronic devices are mounted on the footwear to realize various useful functions and effects. Examples include a wireless communication function, a display function, a power generation / storage function, a health management / promotion function, and the like.

また本発明は、ビジネスシューズや安全作業靴などフォーマル性や足の被覆保護が要求される履物だけでなく、ファッション性が重視されるパンプスやハイヒールなどの婦人用履物やブーツ、耐久性や耐候性が強く要求される登山靴やウォーキングシューズ、スポーツシューズなどの履物に幅広く適用可能である。   The present invention is not only for footwear that requires formality and foot protection, such as business shoes and safety work shoes, but also for women's footwear and boots such as pumps and high heels that emphasize fashion, durability and weather resistance. Can be widely applied to footwear such as mountaineering shoes, walking shoes, and sports shoes, which are strongly demanded.
