【発明の詳細な説明】 本発明は改良された縫付けはだしたび、その製造方法な
らびにその製造時に使用する中型に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved sewing machine, a method of manufacturing the same, and a medium used in the manufacturing.

一般に普及しているはだしたびは、胛布とゴムまたは合

してゴム糊によって胛布に貼付けて作られる吊込み貼付
けはだしたびの２種に分けられるが、いずれも長所と短
所とを有し、満足できるものではない。Generally popular barefoot are made by sewing cloth and a ground sole made of rubber or synthetic resin (hereinafter simply referred to as grounding sole), and sewn barefoot, which is made by sewing the grounding sole with adhesive. There are two types of hanging tapes, which are made by pasting them onto the cloth using rubber glue, but both have advantages and disadvantages and are not completely satisfactory.

、更にまた爪先部の形成に当っては表、裏布および補強
布を重ねた状態でひだを取りなから縫着を行う必要があ
るため、ひだがかたよって部分的に大きなしわを生じる
危険が多く、このため外観を害し、また履用時にしわが
足指に当ってこれを傷め易い重大な欠点がある。To be more specific, each time I start sewing, I sew the cloth and the inner sole with their back sides facing out, leaving a certain seam allowance around the periphery, then turn it inside out and sew the cloth and the inner sole together. The surface of the sole is exposed, the ground sole is placed on top of the inner sole, a thread is passed through the periphery of the stitched cloth and the inner sole, and overlock stitched onto the ground sole. It is attached mostly by sewing, so it is lightweight, and the sole and its surroundings are flexible, which has the advantage of good adhesion to the foot and good curling of the foot. Because each stitch has to be made exactly the same, it takes a lot of effort and time to make the fabric.Also, the seam allowance for sewing the laces and the insole are all on the inside of the laces, and the toes of the laces are too thick. A thick reinforcing piece of cloth is sewn to the heel area, and the seam allowance around the edge is on the inside of the heel, so the internal volume of the toe area is significantly reduced, causing the toes to hit the toes when worn. There is a risk of damage, and furthermore, when forming the toe part, it is necessary to sew the front, lining, and reinforcing fabrics overlapping each other without removing the pleats, so the folds may be uneven and some parts may be large. There is a serious disadvantage that there is a high risk of wrinkles forming, which impairs the appearance, and that the wrinkles are likely to hit the toes and damage them when worn.

またこのためひだを両側縁に分散させて先端にしわが生
じるのを防止することも考えられるがこのようにすると
爪先部が扁平状態に仕上りこれまた指を損傷する欠陥を
生じる。For this reason, it may be possible to prevent wrinkles from forming at the tip by dispersing the pleats on both side edges, but this would result in a flattened toe, which would also cause a defect that could damage the fingers.

従って従来の縫付けはだしたびでは胛部および中底の爪
先部分を実際の足指の巾より大きくしてできるだけ内容
積に余裕をもたせる手段が採用されているが、このよう
にした場合には仕上ったたびの親指部および四指部が実
際の足の形状より著しく巾広となり、扁平になって外観
が害され、また縫付は時に発生するしわはむしろ大きく
なって足指を損傷し易いばかりでなく、指との密着性が
損われる欠点があった。Therefore, in the conventional sewing method, the toe part of the toe part and the insole are made larger than the actual width of the toe to make the inner volume as much as possible, but in this case, The finished thumb and all four toes become noticeably wider and flatter than the actual shape of the foot, spoiling the appearance, and the wrinkles that sometimes occur due to sewing become larger, which can easily damage the toes. In addition, there was a drawback that the adhesion with fingers was impaired.

更にまた接地底の縫付けは、通常かかと部から始められ
側縁を経て最後に爪先部に及ぶものであるが、この場合
縫付けは勘を頼りに適度にひだを取りながら行わなけれ
ばならないので、接地底の最先端と胛部の最先端とを完
全に一致させることは非常に難しく左右いづれか偏倚し
た状態で縫付けられることがしばしばあり、かくでは外
観が損われるのは勿論、履用感が悪く、また所々に足に
当る部分が発生するなど多くの欠陥を生じるおそれが多
々存在した。Furthermore, the sewing of the ground sole usually begins at the heel, passes through the side edges, and finally reaches the toe, but in this case, the sewing must be done by intuition and while taking out the folds appropriately. It is extremely difficult to match the leading edge of the ground sole with the leading edge of the laces, and they are often sewn to one side or the other. There was a risk that many defects would occur, such as poor contact with the feet and the occurrence of parts that hit the feet in some places.

更に重大なことは、この種のはだしたびでは接地底の周
縁に縫糸がかくれる凹条溝を設け、この四条溝に沿って
かかり縫いをなす他に、更にこの凹条溝に沿って六方ミ

方ミシンの嘴状受片を挿し込むことができず、爪先部の
六方ミシン縫いは指付根部を横に一直線に短絡して行わ
ざるを得す、従って爪先部の結合は他の部分に比較して
不十分となる重大な欠陥があった。What is more important is that in this type of sewing, a concave groove is provided on the periphery of the grounding sole to hide the sewing thread, and in addition to sewing along these four grooves, stitches are also made in six directions along this concave groove. Machine sewing is often required, but as mentioned above, there is a seam allowance on the inside of the toe, and both the thumb and all four fingers are finished in a flat state, so the inside of the toe can be sewn. It is not possible to insert the beak-shaped receiver of the hexagonal sewing machine, so the hexagonal sewing machine stitching of the toe part has to be done by short-circuiting the base of the finger horizontally in a straight line, so the connection of the toe part is compared to other parts. There were serious deficiencies that made it inadequate.

他方、貼付けはだしたびは構成された胛部を金属製の中

入も自由であり、指の損傷をほとんど回避できるなど多
くの利点を有する。On the other hand, when pasting is done, cover the constructed fins over a metal medium mold, hang the periphery of the shank part onto the midsole placed on the bottom of the medium sized mold, and attach the bottom to the bottom using rubber glue. In this case, a medium mold is used, and the laces, midsole, and ground sole are pasted on it, and then heated and vulcanized to form it, so it is often molded. The internal volume is the same volume and shape as the medium size that matches the shape of the foot, and each time it is obtained, it is finished with a constant volume and shape, and the laces and the ground sole are tightly connected with rubber glue. This prevents water from seeping through the joint edges, and the manufacturing process is significantly more efficient than sewing. In particular, it is possible to interpose a rubberized cloth on the inner surface of the reinforcing cloth at the toe and heat and vulcanize it on a medium size. As a result, the thumb and four fingers are finished in a bulging shape similar to the toes of the foot, and can maintain their shape for a long time, and each time they are made in this way, they have a good appearance and can be inserted freely. It has many advantages, such as being able to almost avoid finger damage.

しかしながらこの吊込み貼付けたびでは胛部と中底と接

仕上ったたびの底は剛直で縫付けたびに比較して履用感
が劣り、また底の屈曲性も悪く、足のかえりが十分でな
い欠点がある。However, each time this suspension is attached, it is necessary to firmly connect the three parts, the lace part, the insole, and the grounding sole, with rubber glue, without using sewing. It is necessary to surround the inner sole and interpose a core such as a rubber sheet between the inner sole and the grounded sole, and then apply rubber glue to the entire surface and vulcanize it, so the bottom of each case is made of thick cloth and rubber. The layers are laminated alternately and become vulcanized and hardened,
The finished sole is stiff and less comfortable to wear than the finished one, and the flexibility of the sole is also poor, with the drawback that the foot is not sufficiently curved.

更にまた貼付けたびにおける重大な欠点の一つは股部に
おける足とたびとの密着性が十分でなく、足の安定性が
損われることである。Furthermore, one of the serious drawbacks in each application is that the adhesion between the foot and the foot in the crotch region is insufficient, which impairs the stability of the foot.

従って従来胛部の股部の形状を種々変更して股部の密着
を計ることが提案されているが、どのように胛部を裁断
しても股部の密着性はほとんど改善されなかった。Therefore, it has been proposed to improve the adhesion of the crotch by variously changing the shape of the crotch of the lace, but no matter how the lace is cut, the adhesion of the crotch has hardly been improved.

すなわち胛部を中底上に吊込むに当っては、まず胛部の
股部を中型の股部に十分引入れて密着させ、ついで他の
部分を吊込むものであるが、爪先部の吊込みに際しては
股部の胛部が爪先方向に強く引かれるため、折角始めに
股部を中型に十分密着させておいても股部の胛部は中型
股部分から引離される結果となり、このため仕上ったた
びはこれを履用すると股部に空隙が存在し、所謂股部分
が浮く結果となって、はだしたびの生命である足との密
着性、足の安定性が著しく害される重大な欠陥を回避で
きない。In other words, when suspending the laces onto the insole, first the crotch of the laces is fully pulled into the medium-sized crotch so that they are in close contact with each other, and then the other parts are hung. Because the crotch laces are strongly pulled toward the toes, the crotch laces end up being pulled away from the medium crotch even if the crotch is brought into close contact with the medium size at the beginning. When you wear this, there is a gap in the crotch area, which causes the crotch to float, which is a serious defect that seriously impairs the stability of the foot and the contact with the foot, which is the lifeblood of every time you wear it. It cannot be avoided.

さらにまた吊込み貼付けでは全周縁の吊込み巾を一定に
保つことがむつかしく、最初に吊込まれる踵部分の吊込
み巾は種々変動し、これにつれて他部分の吊込み巾も変
化するにいたる。Furthermore, in hanging attachment, it is difficult to keep the hanging width of the entire periphery constant, and the hanging width of the heel part, which is hung first, varies, and the hanging width of other parts changes accordingly.

たとえば踵部が余りに深く吊込まれると胛部は後方に片
寄った状態となりまた小さ過ぎると逆に前方に片寄った
状態となり、左右の側縁においても同様に吊込み巾の不
同が生じて、外観が害われ、履用感が害されるに到るも
のである。For example, if the heel is hung too deeply, the heel will be biased backwards, and if it is too small, it will be biased forward, and the width of the heel will also be uneven on the left and right side edges, resulting in an appearance. This results in damage to the wearer's wear and the feeling of wearing the product.

また貼付けはだしたびでは最後に六方ミシン縫いを施し
て胛部吊込み部分と中底および接地底を縫着することが
しばしば実施されており、好ましいことであるとされて
いるが、この場合吊込み巾に不同を生じるときはこの六
方ミシンの縫糸が胛部あるいは中底を刺通しない部分が
発生してたびの寿命を著しく短かくする欠陥を生じる。In addition, when pasting is done, it is often done using a hexagonal sewing machine to sew the hanging part of the lace part, the midsole, and the ground sole at the end, and it is said to be a preferable thing to do, but in this case, When there is a difference in the sewing width, the sewing thread of this hexagonal sewing machine does not pierce the hexagonal part or the inner sole, resulting in a defect that significantly shortens the life of the hexagonal sewing machine.

本発明は従来の縫付けはだしたびの欠陥をすべて排除し

規な縫付けはだしたびを提供することを第一の目的とす
るものである。The present invention eliminates all the defects of the conventional sewing machine, and also has a big toe and four toes shaped like an actual foot and has enough inner volume to allow fingers to be inserted freely. However, there are no wrinkles, it feels extremely comfortable to wear, and it adheres closely to the foot to ensure safety.Furthermore, the sole is secured by machine stitching around the entire periphery, allowing for highly efficient production. The primary purpose of this product is to provide a seamless sewing experience.

徴とする縫付けはだしたびに係る。In other words, the first aspect of the present invention is to provide a toe portion and a flange portion (hereinafter simply referred to as the lace portion) whose toe portion and side edges are enlarged by the width necessary for hanging and pasting, and a toe portion and heel portion periphery only. The inner sole is expanded by the width of the seam allowance (hereinafter referred to simply as the inner sole), and the heel and crotch of the fingers are sewn together, and the remaining periphery is attached by hanging. They are combined to form a combined body, and a ground sole made of rubber or synthetic resin is placed over the middle sole of this combined body, and the combined body and the ground sole are joined by sewing along the periphery. The characteristic sewing is applied every time.

はだしたびの製造方法に係る。Further, the second invention of the present invention is characterized in that the toe part and the side edges are enlarged by the width necessary for hanging and pasting, and the toe part and the heel part are only enlarged by the width for sewing. , the laces and the insole are sewn together at only two places, the heel and the crotch of the fingers, and the medium size is inserted between the laces and the insole of this partially joined body. The combined body and the medium size are combined, the toe part and the side edge of the lace part are suspended and pasted onto the periphery of the insole, and a rubber or synthetic resin material is placed on the insole of the combined body of the lace part and the insole obtained in this way. This relates to a manufacturing method for each sewn-up product, which is characterized in that the ground-contact soles of the present invention are overlapped, and sewing is performed along the entire periphery of the two to connect the two.

たび製造のための中型に係る。Furthermore, the third aspect of the present invention is a toe part and side edges of the toe part which are enlarged by the width required for hanging and pasting, and a middle sole of which only the toe part and the heel periphery are enlarged by the sewing width. It is a medium-sized product that has a shape that matches the shape of the foot, and is used to connect the two by sewing the heel and the crotch of the toes, and by hanging the remaining peripheral part, and has a shape that matches the shape of the foot. The present invention relates to a medium-sized mold for use when wearing clothes, characterized in that the lower edge of the heel part and the lower peripheral edge of the heel part are notched to accommodate a seam allowance for sewing the above-mentioned lace part and the midsole together.

本発明によれば縫付けはだしたびであるにもかかわらず

とがなく履用時の足の安定を確保できるなど幾多の効果
を達成することができる。According to the present invention, there is no need to remove the pleats while sewing the toe part of the lace part and the insole even though the sewing is done every time, so a special sewing machine for removing the pleats is used. There is no need to sew, and since there is no pleat stitching, there is no risk of large wrinkles in the toe area, even though the toe area has the same size and shape as the toe of the foot, and there is no seam allowance inside the toe area. Because there are no toes, the toe area has sufficient internal volume to allow the toe to be inserted freely, and there is no risk of damaging the toe when wearing the shoe.Furthermore, the toe area fits tightly against the foot and does not lift up, making it easy to wear. It can achieve many effects such as ensuring stability of the feet during use.

いので全周縁に亘って胛部あるいは中底を確実に刺通し
た強固な六方ミシン縫いを達成できる大きな利点がある
。Furthermore, since the toe part of the bare foot according to the present invention has a sufficient internal volume, the grounding sole is fixed by hexagonal sewing around the entire periphery including the periphery of the toe, which was impossible with conventional sewing hands. Therefore, production efficiency can be significantly improved, and since there is no variation in the hanging width of the periphery, it is possible to achieve strong hexagonal sewing that reliably pierces the laces or insole over the entire periphery. There are big advantages.

縁をミシン縫いする本発明の方法を実施することによっ
て始めて得られるものである。However, each of the above-mentioned advantages can be achieved by first joining the laces and insole by sewing only the crotch of the toes and heel, and then inserting a medium-sized piece that matches the shape of the foot into this joined body. The heel part is brought into close contact with each part of the medium-sized part, and the toe part and side edge part of the lace part are suspended and pasted onto the insole, and the combined body of the lace part and the insole assembled in this way This can only be obtained by carrying out the method of the present invention, in which the ground sole is stacked on top of the inner sole and the peripheral edge is sewn by a sewing machine.

浮き上ることがなく側縁は左右とも所定の吊込み巾で貼
付けられるに到るものである。That is, according to the method of the present invention, the lace part and the insole are joined by sewing only the finger crotch part and the heel part, and then the medium size is inserted and assembled. The seam allowance of the upper part is aligned with the crotch of the fingers and the periphery of the heel of the bottom of the midsole, and the combined body of the laces and the midsole is in close contact with the surface of the midsole, so that the toe part is sufficiently suspended. However, the finger joints do not lift up and the side edges can be attached with a predetermined hanging width on both the left and right sides.

しかしてこれらの効果を確実にするためには爪先部およ
び側縁を吊込み貼付けに必要な巾だけ拡大した形の胛部
と、指股部と踵部周縁だけを縫代の巾だけ拡大した中底
を用いることが必要である。However, in order to ensure these effects, the toe and side edges were enlarged by the width necessary for hanging and pasting, and only the crotch of the fingers and the circumference of the heel were enlarged by the width of the seam allowance. It is necessary to use an insole.

あるいはさらに側縁および爪先部の周縁を吊込み貼付け
に用いる中型の底面の相当部分よりも例えば３〜６ｍｍ
拡大した中底を用い、前記の方法で結合して用いること
が好ましい。Alternatively, the side edges and the circumferential edge of the toe should be, for example, 3 to 6 mm wider than the corresponding part of the bottom of the medium size used for hanging and pasting.
It is preferable to use an enlarged insole and to connect it by the method described above.

また前述のように本発明の方法によれば胛部と中底との

よび踵部下周縁を縫付部の縫代が収容されるように切欠
いたものを使用するとよい。Further, as described above, according to the method of the present invention, when the medium size is inserted into the combined body of the lace part and the midsole and assembled, the seam allowance around the finger crotch part and the heel part of the bottom surface of the medium size Since it is exposed to the periphery of the heel and engages, thus ensuring close contact between the two, the lower edge of the toes and the lower periphery of the heel should be accommodated in the seam allowance for the medium size. It is best to use one with a notch cut out.

しかしてこの中型は前述の爪先部および側縁の吊込み貼
付けのためにだけ使用されるものであるので、この中型
は吊込み前に胛部と中底との結合体内に挿入組合せでき
、吊込み貼付は後は容易に離脱できる寸法、形状でなけ
ればならない。However, since the medium-sized lever is used only for hanging and attaching the toe part and side edge, this medium-sized lever can be inserted and assembled into the joint between the clasp part and the insole before hanging. Once attached, the size and shape must be such that it can be easily removed.

本発明者は胛部と中底とを指股部と踵部のみの縫付けで

た中型と同一形状のもので十分その目的を達成でき、何
等伸縮可能の特殊な中型を使用する必要がなく、従って
著しく高い作業能率で縫付けはだしたびを生産できるこ
とを発見した。The present inventor has found that when the laces and the insole are connected by sewing only the toe and heel sections, a medium-sized one that is the same shape as the one used for conventional all-periphery hanging attachment is sufficient to achieve the purpose. It has been discovered that there is no need to use any special medium size that can be expanded and contracted, and that it is therefore possible to produce sewn strips with extremely high work efficiency.

この中型は金属製でも木製でもよい。This medium size can be made of metal or wood.

者が確実に縫合される。The combined body of the lace part and the midsole and the ground sole can be sewn according to the conventional sewing method, but the lace part and the inner sole made by the method of the present invention can be sewn together using the conventional sewing method. The internal volume of the toe part of the combined body is wide enough and thick enough to freely accommodate the beak-shaped receiver of the hexagonal sewing machine, so the hexagonal sewing machine is sewn around the entire circumference along the concave groove of the grounding sole. In this case, the midsole and the laces overlap at a constant distance over the entire circumference, so the laces, the midsole, and the ground sole overlap.
The patient is sutured securely.

かくして縫付けられた接地底の周端縁はこれを胛部の下
縁にかがり縫いすることにより接地底の結合をより強固
にすることができる。The thus sewn peripheral edge of the ground sole can be overlocked to the lower edge of the lace to further strengthen the connection of the ground sole.

よい。As a grounding sole, the present inventor proposed the Jikko 5
As described in Publication No. 0-31145, a thin heel reinforcing piece is provided at the periphery of the heel portion of the ground-contacting sole and is integral with the sole body, and a large number of pairs of radially long protrusions are formed on the lower surface of the periphery. The gold edge of the reinforcing piece may be overlocked to the heel of the heel by passing a needle through these protruding stripes, and as proposed separately, there are many paired protruding stripes on the outer periphery of the ground sole.
