【産業上の利用分野】
本発明は、胛被の履口部前部と爪先部との間の両側部に、靴中底より高位置にその上縁を有する靴底の該上縁から切欠開口している切欠部が形成されており、該切欠部の略中央を横切る状態で胛被と係合せしめられた胛被補強用のウェッチバンドがその両端を靴底に固着されていて、通気性に優れていると共に足の裏，爪先部の保護を図ることのできる靴を効率良く製造することのできる靴の製造方法に関するものである。
【０００２】
【従来の技術】
従来、通気性に優れた靴として、胛被の一部がバンド等により形成されているサンダルや胛被の一部に切欠部が形成されている靴があった。
前者のサンダルは、足の露出面積が大きいので通気性が非常に優れているが、逆に胛被で覆われる部分が非常に狭く、多くの場合爪先部には胛被が存在せず履用時に足の爪先部分が露出するので、履用場所によっては足を保護するという点では劣るという欠点があり、また後者の胛被の一部に切欠部が形成されている靴としては、胛被の靴底から離れた位置に切欠部が形成されている靴があったが、このような靴は履用したときにこの切欠部から下方の胛被に覆われる足の面積が広いので、蒸れ易さは切欠部の形成されていない靴とそれほど変わらないという欠点があった。
【０００３】
上記した欠点を解消し得る靴として、胛被の履口部前部と爪先部との間の両側部に、靴底の上縁から切欠開口している切欠部が形成されており、この切欠部の略中央を横切る状態で胛被と係合せしめられた胛被補強用のウェッチバンドがその両端を靴底に固着されている靴がある。このような切欠部が靴底の上縁から形成されている靴は、爪先部を胛被で覆われるので履用者の足の比較的弱い爪先部が保護され、且つ切欠部が靴底の上縁から切欠開口しているのでこの切欠部では発汗し易い足の裏側近辺まで開口しているので通気性が非常に良く蒸れ難いという効果がある。
【０００４】
この切欠部が靴底の上縁から形成されている靴は、以下のようにして製造されていた。
先ず、靴金型の表面に靴中底を載置すると共に切欠部を形成される所定の部位が切欠されている胛被素材を吊り込んで、前記靴中底の裏側に胛被素材の下縁部を貼着又は縫着した後、靴底を形成するのである。靴底を形成するには、予め形成しておいた靴底を靴中底に貼着する方法と、靴金型に吊り込まれ靴中底に貼着又は縫着された胛被素材を靴底形成用金型に装着した後にこの靴底形成用金型と靴中底との間に靴底形成用樹脂を注入・充填して靴底を射出成形する方法とがある。
【０００５】
前者の靴底を貼着する方法は、靴中底と靴底との貼り合わせ部及び胛被素材が靴中底と靴底との間に入り込んでいる部分が表面に露出するので、外観が悪いだけでなく、靴底の貼着作業が手作業により行われるので生産効率が悪いと共に経済的でないという欠点があった。
従って、後者の靴底形成用樹脂を注入・充填して靴底を射出成形する方法が一般に行われており、胛被素材と共に靴中底の側面を覆った状態に靴底が形成されるので外観に優れていると共にこの製造工程を機械化できるので量産が可能で効率良く且つ経済的に製造することができるのである。しかしながら、この方法で切欠部が靴底の上縁から形成されている靴を製造しようとすると、胛被素材が切欠部には存在しないために靴中底全周に亘って胛被素材が貼着されていないことから、靴底形成用樹脂が注入・充填時に胛被素材の切欠部端縁で靴中底と靴底形成用金型との間から靴中底側に漏れ出るので、靴底の上縁を靴中底より高い位置に至るまで形成することが困難であるという欠点があり、その結果外観が悪いばかりでなく靴中敷上に砂利等の異物が入り込み易いという欠点があった。
【０００６】
【発明が解決しようとする課題】
本発明は、胛被の履口部前部と爪先部との間の両側部に、靴中底より高位置にその上縁を有する靴底の該上縁から切欠開口している切欠部が形成されており、この切欠部の略中央を横切る状態で胛被と係合せしめられた胛被補強用のウェッチバンドがその両端を靴底に固着されていて、通気性に優れていると共に足の裏，爪先部の保護を図ることのできる靴を効率良く製造することのできる靴の製造方法を提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明者は、かかる課題を解決すべく鋭意検討した結果、胛被の履口部前部と爪先部との間の両側部に、靴中底より高位置にその上縁を有する靴底の該上縁から切欠開口している切欠部が形成されており、該切欠部の略中央を横切る状態で胛被と係合せしめられた胛被補強用のウェッチバンドがその両端を靴底に固着されている靴を製造するに際し、胛被素材の所定位置にウェッチバンドを係合すると共に、胛被素材の切欠部を形成するための切除部と靴底に固着される下縁部の固着部とから成る切欠部相当部からウェッチバンドの位置する部位のみを切除し、残った切欠部相当部と該胛被素材との靴底への固着部同士の少なくとも一部が連続し且つ該切欠部相当部の輪郭を形成する切り込みを設け、ウェッチバンドの靴底に固着される下縁部の固着部と切欠部相当部の固着部とを互いに仮止めし、靴金型に前記胛被素材を吊り込んで胛被形状に縫製すると共に靴中底にウェッチバンド，胛被素材，切欠部相当部のそれぞれ下縁部の各固着部を固着して胛被形状体を形成し、該胛被形状体を靴底形成用金型に装着した後に、該胛被形状体の靴中底とウェッチバンド，胛被素材，切欠部相当部の各固着部と前記靴底形成用金型との間に靴底形成用樹脂を注入・充填し靴底を射出成形した後に切欠部相当部の切除部を靴底の上縁に沿って切除すれば、靴底の成形を生産効率に優れている射出成形により、靴底形成用樹脂の注入・充填時にこの靴底形成用樹脂が胛被素材の切欠部端縁で靴中底と靴底形成用金型との間から漏れ出ることなく靴底の上縁を靴中底より高い位置に至るまで形成することができることを究明して本発明を完成したのである。
【０００８】
また、ウェッチバンドの縁部及び／又は胛被の切欠部の縁部に、予めバイアステープを縫着すると、製造された靴のウェッチバンド及び／又は胛被の縁部が保護され且つ意匠効果を向上させることができることも究明したのである。

先ず、本発明方法により製造される靴について簡単に説明する。
図面中、１は下縁部外面を靴底３にまた下縁部内面を靴中底２に固着されており、履口部1a前部と爪先部1bとの間の両側部に、靴中底２より高位置に位置せしめられている靴底３の上縁3aから切欠開口している切欠部1cが形成されている胛被である。
４は前記切欠部1cの略中央を横切る状態で胛被１と係合せしめられた胛被補強用のウェッチバンドであり、両端が靴底３と靴中底２とに固着されている。
【００１１】
上記した如く構成されている靴を製造する本発明方法を実施するには、先ず図２に示す如く胛被素材６の所定位置にウェッチバンド４を係合すると共に、胛被素材６の切欠部1cを形成するための切除部7aと靴底３に固着される下縁部の固着部7bとから成る切欠部相当部７からウェッチバンド４の位置する部位のみを切除する。
【００１２】
胛被素材６の所定位置にウェッチバンド４を係合するには、図示しないが胛被素材６の履口部1aを形成される部位の前部と爪先部1bを形成される部位との間の前胛部の表面側にウェッチバンド４の中央部を重ね合わせてを両者を縫い合わせたり、またウェッチバンド４を２分割しこの２分割した各ウェッチバンド片をそれぞれ切欠部1cに対応させて一端を前記した如き胛被素材６の前胛部の表面側に縫い合わせたりしても良いが、例えば図示した実施例の如く胛被素材６の履口部1aを形成される部位の前部と爪先部1bを形成される部位との間の前胛部であってウェッチバンド４を設ける所定位置に間隔を隔てて平行な２条の切り込み８を形成し、ウェッチバンド４をその両側が胛被素材６の表面側に位置するように前記切り込み８，８に挿通させて係合させると、胛被素材６にウェッチバンド４を係合する作業を容易に行うことができて好ましい。
【００１３】
このとき、図示した実施例の如くウェッチバンド４の位置する部位のみを切除され残った切欠部相当部７と胛被素材６とのそれぞれ靴底３に固着される固着部7b，6b同士の少なくとも一部が連続し且つ切欠部相当部７の輪郭を形成するように切欠部相当部７の切除部7aの胛被素材６との境界部に切り込み6aを設ける。
【００１４】
また、ウェッチバンド４の縁部及び／又は胛被１の切欠部1cの縁部を囲むようにバイアステープ11を縫着すると、ウェッチバンド４の縁部及び／又は胛被１の切欠部1cの縁部が保護され且つ意匠効果を向上させることができて好ましい。
【００１５】
このバイアステープ11は、ウェッチバンド４の縁部に縫着する場合には、胛被素材６に係合する前に予め縫着しておく。また、胛被１の切欠部1cの縁部に縫着する場合には、前記切り込み6aを設けた後に前記胛被１の切欠部1cの縁部に相当する胛被素材６と切欠部相当部７の切除部7aとの境界部にバイアステープ11を縫着するのであるが、製造された靴の表面にバイアステープ11の端部が露出しないように切り込み6aを切欠部相当部７の固着部7bに至るまで設けておき、このバイアステープ11の端部が靴底３に隠蔽されるように胛被素材６の固着部6bの一部にも縫着しておくことが好ましい。
【００１６】
そして、ウェッチバンド４の靴底３に固着される下縁部の固着部4aと残った切欠部相当部７の固着部7bとを、その縁部同士を互いに突き合わせて糸等の仮止め手段により仮止め９する。
【００１７】
次いで、ウェッチバンド４を係合された胛被素材６を靴金型12に吊り込みながら踵部を縫い合わせて胛被形状に縫製すると共に、靴金型12上に載置しておいた靴中底２に胛被素材６の下縁部を接着剤で貼着したり糸で縫着したりすることによって固着して胛被形状体５を形成する。
【００１８】
そして、形成された胛被形状体５を靴金型12と共に靴底形成用金型13に装着し、胛被形状体５の靴中底２とウェッチバンド４，胛被素材６，切欠部相当部７の各固着部4a，6b，7bと前記靴底形成用金型13との間に靴底形成用樹脂10を注入・充填し靴底３を射出成形する。
【００１９】
しかる後、切欠部相当部７の切除部7aを靴底３上縁3aに沿って切除することによって靴が完成する。
【００２０】
【発明の効果】
以上に詳述した如く本発明に係る靴の製造方法は、
▲１▼胛被に形成されている切欠部が靴底上縁から切欠開口しているので通気性が良く、
▲２▼靴底上縁が靴中底より高位置であるから、サンダル等の靴中底から切欠部が形成されている胛被を有する靴と比較して、靴内に砂や石等の異物が入り込み難く足の裏の保護を図ることができ、
▲３▼切欠部が胛被の履口部と爪先部との間の両側部に形成されていて爪先部は胛被で覆われているので、爪先の保護を図ることができる

[Industrial application fields]
In the present invention, notches are formed on both sides between the front portion of the cuff portion and the toe portion of the cover, and the notches are opened from the upper edge of the shoe sole having the upper edge at a position higher than the insole. The heel cover wetting band that is engaged with the heel in a state of crossing substantially the center of the notch is fixed to the shoe sole at both ends, and has excellent breathability and the sole of the foot. The present invention relates to a shoe manufacturing method capable of efficiently manufacturing a shoe capable of protecting the toe portion.
[0002]
[Prior art]
Conventionally, as shoes having excellent breathability, there have been sandals in which a part of the cover is formed by a band or the like, and shoes in which a notch is formed in a part of the cover.
The former sandals have very good breathability due to the large exposed area of the foot, but conversely the area covered by the heel is very narrow, and in many cases the heel is not present on the toe. Sometimes the toe portion of the foot is exposed, so there is a disadvantage that it is inferior in terms of protecting the foot depending on the place of wearing, and as a shoe with a notch formed in a part of the latter, There was a shoe with a notch formed at a position away from the sole of the shoe, but when such a shoe was worn, the area of the foot covered by the undercoat from this notch was large, so it was stuffy There was a drawback that the ease was not so different from that of shoes with no notch.
[0003]
As a shoe that can eliminate the above-mentioned drawbacks, a notch that has a notch opening from the upper edge of the shoe sole is formed on both sides between the front part of the mouth part and the toe part of the cover. There is a shoe in which a heel-covering wetting band that is engaged with the heel in a state of crossing substantially the center of the heel is fixed to the sole. In a shoe in which such a notch is formed from the upper edge of the shoe sole, the toe portion is covered with a cover, so that the relatively weak toe portion of the wearer's foot is protected, and the notch portion of the shoe sole is protected. Since the notch is opened from the upper edge, the notch is open to the vicinity of the back side of the foot where sweating easily occurs.
[0004]
A shoe in which the notch is formed from the upper edge of the shoe sole has been manufactured as follows.
First, the shoe insole is placed on the surface of the shoe mold and a cover material in which a predetermined part for forming a notch is cut is hung, and the back of the shoe material is placed on the back side of the shoe insole. After adhering or sewing the edges, the sole is formed. In order to form a shoe sole, a method of attaching a preformed shoe sole to a shoe insole and a cover material that is suspended in a shoe mold and attached to or sewn on the shoe sole is used as a shoe. There is a method in which a shoe sole is injection-molded by injecting and filling a shoe sole forming resin between the shoe sole forming die and the shoe insole after being mounted on the sole forming die.
[0005]
The former method of attaching the shoe sole is such that the portion where the insole of the shoe insole and the shoe sole and the heel material enters between the shoe insole and the sole is exposed on the surface, so the appearance is In addition to being bad, there is a drawback in that production efficiency is low and economical because the work of attaching the shoe sole is performed manually.
Therefore, the latter method of injecting and filling the shoe sole-forming resin and injection-molding the shoe sole is generally performed, and the shoe sole is formed so as to cover the side surface of the shoe insole together with the cover material. Since the appearance is excellent and the manufacturing process can be mechanized, it can be mass-produced and can be manufactured efficiently and economically. However, if an attempt is made to manufacture a shoe in which the notch is formed from the upper edge of the shoe sole by this method, the cover material is affixed over the entire circumference of the shoe insole because the cover material does not exist in the notch. Since it is not worn, the shoe sole-forming resin leaks from between the shoe insole and the shoe sole-forming mold to the shoe insole side at the notch edge of the cover material when pouring and filling. There is a disadvantage that it is difficult to form the upper edge of the bottom up to a position higher than the insole of the shoe, and as a result, not only the appearance is bad, but also foreign matter such as gravel easily enters the insole. It was.
[0006]
[Problems to be solved by the invention]
In the present invention, notches are formed on both sides between the front portion of the cuff portion and the toe portion of the cover, and the notches are opened from the upper edge of the shoe sole having the upper edge at a position higher than the insole. The heel cover wetting band, which is engaged with the heel in a state of crossing almost the center of the notch, is secured to the soles at both ends, and has excellent breathability and the sole of the foot. It is an object of the present invention to provide a shoe manufacturing method capable of efficiently manufacturing a shoe capable of protecting the toe portion.
[0007]
[Means for Solving the Problems]
As a result of intensive studies to solve such problems, the present inventor has found that the shoe sole has an upper edge at a position higher than the shoe insole on both sides between the front part of the mouth part and the toe part of the cover. A notch is formed in the notch opening from the upper edge, and a heel reinforcement wetting band that is engaged with the heel in a state of crossing substantially the center of the notch is fixed to the sole. When manufacturing a shoe, a wet band is engaged at a predetermined position of the cover material, and a cut-out portion for forming a notch portion of the cover material and a fixing portion of a lower edge portion fixed to the shoe sole are formed. Only the part where the wet band is located is cut out from the notch equivalent part, and at least part of the remaining notch equivalent part and the fixing part to the shoe sole of the cover material are continuous, and the contour of the notch equivalent part The lower edge is fixed to the sole of the wet band with a notch forming Temporarily fix the fixing part and the fixing part corresponding to the notch part to each other, hang the cover material on the shoe mold and sew it in the shape of the cover, and it corresponds to the wet band, the cover material and the notch part on the shoe insole After fixing each fixing part of each lower edge part of a part to form a heel-shaped body, and mounting the rim-shaped body on a shoe sole forming mold, the insole of the hood-shaped body and a wet band , After the shoe sole forming resin is injected and filled between each fixing portion of the cover material, the notch portion corresponding portion and the shoe sole forming mold, and the shoe sole is injection-molded, the cut portion corresponding to the notch portion is formed. By cutting along the upper edge of the shoe sole, the shoe sole forming resin is injection-molded with excellent production efficiency. Forms the upper edge of the shoe sole up to a position higher than the shoe insole without leaking from between the shoe insole and the shoe forming mold at the edge Than is the present invention has been completed to investigate that can Rukoto.
[0008]
In addition, when a bias tape is sewn in advance to the edge of the wet band and / or the edge of the notch of the cover, the wet band and / or cover of the manufactured shoe is protected and the design effect is improved. They also found out that they could do it.
[0009]
