Description
本発明は、防水靴の裏材に関するものである。 The present invention relates to a backing material for waterproof shoes.
従来、防水機能を備えた防水靴には防水素材の裏材が内装されているが、裏材は１枚または複数の部材を裁断し、それらの部材を縫合して袋状の裏材としている。複数の部材から構成してなる裏材は、例えば特開２００２−１４２８０８に示すように、裏材を前後に横分割した爪先裁断部材と踵裁断部材とで形成し、この爪先裁断部材を、前記裏材の底部分を爪先・踵を結ぶ方向で縦分割するとともに、左右の甲被部分を一体に連結した形状とし、この踵裁断部材を、前記裏材の底部分を爪先・踵を結ぶ方向で縦分割するとともに、左右踵部分を一体に連結した形状とする一方、これら爪先裁断部材と踵裁断部材の上記縦横分割部を縫合するとともに、これら縫合部を覆って防水テープを貼着することが開示されている。 Conventionally, waterproof shoes having a waterproof function are internally provided with a backing material made of a waterproof material, but the backing material is cut into one or a plurality of members, and these members are stitched to form a bag-like backing material. . As shown in JP-A-2002-142808, for example, a backing material composed of a plurality of members is formed by a toe cutting member and a scissor cutting member obtained by horizontally dividing the backing material in the front and rear, and this toe cutting member is The bottom part of the backing material is vertically divided in the direction connecting the toes and heels, and the left and right upper parts are integrally connected, and this severing member is connected to the bottom part of the backing material in the direction connecting the toes and heels. And the left and right heel portions are integrally connected to each other, and the toe cutting member and the vertical and horizontal division portions of the chopping member are stitched, and the waterproof tape is attached to cover the stitched portions. Is disclosed.
また、１枚から部材から構成される裏材としては、例えば特開昭５９−１６０４０１で示すように、足裏素材の両側に側片部を一体に形成した基体を防水透湿層をもった単一素材で形成し、該素材片によって足部全般を被包する内装基体を形成し、該内装基体に外被部体を覆着した靴が開示されている。
ところが、複数の部材から構成してなる裏材は、縫合箇所が多く、また各縫合部分が長くなり、そのため縫合作業に手間がかかるとともに各縫合部分から水が浸入しやすかった。また、縫合部分にはテープ貼りして水の浸入を防止するようにするが、縫合部分が多すぎるためテープ貼り作業が大変であり、テープが剥がれ易く、防水機能が低下する。また、１枚から部材から構成される裏材は、足の形状にあわせた側片部材とすることが困難で、特に足の甲回りの形状を平面形状に展開して裁断することが難しく履き心地が悪いという問題点がある。 However, the backing made of a plurality of members has many stitched portions, and each stitched portion becomes long. Therefore, it takes time for the stitching operation and water easily enters from each stitched portion. In addition, a tape is applied to the stitched portion to prevent water from entering, but the tape stitching work is difficult because there are too many stitched portions, the tape is easily peeled off, and the waterproof function is lowered. In addition, it is difficult to use a single-membered backing as a side piece that matches the shape of the foot. In particular, it is difficult to cut the shape of the instep around the foot in a flat shape. There is a problem of uncomfortable.
本発明は上記の点に鑑みてなされてものであって、裏材本体を１枚で形成して縫合箇所が少なく縫合部分が短くなるようにすると共に、防水テープ貼り作業を楽にして作業性を向上させるとともに防水効果も一段と高めるようにし、さらには一層の履き心地を向上させるようにした防水靴の裏材を提供しようとするものである。 The present invention has been made in view of the above points, and it is possible to form a backing main body by one piece so that the number of stitches is small and the stitches are shortened, and the work of attaching waterproof tape is facilitated. It is intended to provide a backing material for waterproof shoes that improves the waterproof effect and further improves the comfort.
本発明は、上記従来技術が有する課題を解決するため、本発明の裏材は裏材本体を１枚の防水素材で形成し、その防水素材の接合縁を縫合し袋状した裏材であって、該裏材の足裏部を爪先から踵にかけて長手方向に縦割りし、かつ内甲側側面部を前後に横割りして、足裏爪先部を有した爪先相当部と、踵部を形成し足裏踵部を有した側面相当部とを連接させた裏布裁断パターンからなり、爪先相当部は爪先先端に切り込み部を形成すると共に、縦割りされた爪先足裏部の側縁と接合される接合縁が形成され、側面相当部には横割りされた内甲側爪先相当部の側縁と接合される接合縁を形成し、踵部には切り込み部を形成すると共に縦割りされた足裏踵部の側縁と接合される接合縁が形成され、これら爪先相当部と側面相当部との接合縁を縫合すると共に、これら縫合部を覆って防水テープを貼着してなることを要旨とする。 In order to solve the above-described problems of the prior art, the backing of the present invention is a backing formed by forming a backing body from a single waterproof material and stitching the joint edges of the waterproof material to form a bag. The foot part of the backing material is vertically divided from the toe to the heel in the longitudinal direction, and the inner side surface part is divided into the front and rear, and the toe-corresponding part having the foot toe part and the heel part It consists of a backing cloth cutting pattern that is formed by connecting a side equivalent part with a foot sole part, and the toe equivalent part forms a notch at the tip of the toe, and the side edge of the vertically split toe sole A joining edge to be joined is formed, a joining edge to be joined to a side edge of the inner toe side toe equivalent part which is divided horizontally is formed on the side surface equivalent part, and a cut portion is formed on the collar part and vertically divided. A joint edge to be joined to the side edge of the sole of the sole is formed, and the joint edge between the toe-corresponding portion and the side-corresponding portion is stitched Rutotomoni, and summarized in that formed by bonding the waterproof tape covering these seamed portions.
本発明の１枚の防水素材によって形成した裏材によれば、縫合箇所が爪先外周部、踵外周部、足底部と内甲側面部だけである。従って、本発明は縫合箇所が少なく、縫合部分の長さも短く、これにより、接合部の縫着に要する作業と時間を従来に対して節約することが出来る。また、各縫合部分は防水テープの貼着作業が短くてすみ、防水効果を高めることができる。 According to the backing formed of the single waterproof material of the present invention, the stitched portions are only the outer periphery of the toe, the outer periphery of the heel, the sole, and the side surface of the instep. Therefore, according to the present invention, the number of stitched portions is small, and the length of the stitched portion is short, thereby saving the work and time required for sewing the joint portion over the conventional method. In addition, each stitched portion requires a short waterproof tape attaching operation, and can enhance the waterproof effect.
さらには、爪先部材と側面部材との縫合部が内甲側だけに位置し外甲側にはないので、足当たりがなく一層履き心地を向上できるとともに靴の外観を高めることができるようになる。 Furthermore, since the stitched portion between the toe member and the side member is located only on the inner shell side and not on the outer shell side, there is no foot contact and the comfort can be further improved and the appearance of the shoe can be enhanced. .
以下、本発明の防水靴の裏材の一実施例について、図面に基づき説明する。図１は裏材の展開図、図２はその裏材の外観斜視図、図３は裏材の縫合部における断面図である。 Hereinafter, an embodiment of a backing material for waterproof shoes according to the present invention will be described with reference to the drawings. FIG. 1 is a developed view of the backing material, FIG. 2 is an external perspective view of the backing material, and FIG. 3 is a cross-sectional view of the stitched portion of the backing material.
本発明の防水靴の裏材１は図1に示すように１枚の防水素材で形成される。そして、裏材１はその防水素材の接合縁を縫合して袋状とし、靴の裏側に装着されるものである。 The backing 1 of the waterproof shoe of the present invention is formed of a single waterproof material as shown in FIG. And the backing material 1 is made into a bag shape by sewing the joint edge of the waterproof material, and is attached to the back side of the shoe.
この裏材1では図1及び図２に示すように足裏底部を爪先から踵にかけて長手方向に縦割りすると共に、内甲側の側面部を前後に横割りして、足裏爪先部２ａを有した爪先相当部２と、足裏踵部３ａを有した側面相当部３との連接された裏材裁断パターンからなる。この裏材1の内甲側の側面部を前後に横分割する接合縁Ｓ２は、いずれの位置でもよいが、足裏底部の不踏部から履き口前方の切欠部にかけて斜めに横分割すれば、裏材の縫合部が足の内側不踏部位置となり、足あたりがなくなる。 In this backing 1, as shown in FIGS. 1 and 2, the bottom part of the sole is vertically divided from the toe to the heel in the longitudinal direction, and the side part on the inner side is divided into the front and the back, so that the sole part 2a of the sole It consists of a backing material cutting pattern in which the toe-corresponding portion 2 and the side-corresponding portion 3 having the sole heel portion 3a are connected. The joint edge S2 that laterally divides the side part on the inner side of the backing 1 may be at any position, but if it divides diagonally from the tread of the sole to the notch in front of the mouth, The stitched portion of the backing becomes the position of the inner depression of the foot, and the foot contact is lost.
このような裏材を構成する爪先相当部２は、裏材の足裏部を爪先から踵にかけて長手方向に縦割りし、その左右に足裏爪先部２ａを一体にした形状とする。また爪先相当部２の先端には略Ｖ字形状の切り込み部４が形成される。足裏爪先部２ａの爪先外周は爪先の外形に沿って円弧状に形成される。よって、爪先相当部２は足裏爪先部の側縁に接合する接合縁Ｓ１として縫合部が形成され、足の爪先形状に立体的に沿うように形成することができる。 The toe-corresponding portion 2 constituting such a backing material has a shape in which the sole portion of the backing material is vertically divided from the toe to the heel in the longitudinal direction, and the sole toe portion 2a is integrated on the left and right. A substantially V-shaped cut portion 4 is formed at the tip of the toe-corresponding portion 2. The outer periphery of the toe of the sole toe portion 2a is formed in an arc shape along the outer shape of the toe. Accordingly, the toe-corresponding portion 2 is formed with a stitched portion as a joining edge S1 joined to the side edge of the sole toe portion, and can be formed so as to conform three-dimensionally to the toe shape of the foot.
また、裏材を構成する側面相当部３は、裏材の足裏底部を爪先から踵にかけて長手方向に縦割りし、踵を覆うような形状とすると共に、前記爪先相当部２の側縁と接合される接合縁Ｓ２が形成される。また踵部５の踵後端には略杯形状の切り込み部６が形成され、足裏踵部３ａの踵外周部には踵の外形に沿って円弧状に形成され、踵部を足の踵形状に立体的に沿うようにすることができる。側面相当部３は、縦割りされた足裏踵部３ａの側縁と接合される接合縁Ｓ３が形成され、また側面相当部３の踵後部には縫合部がないことから、縫い目が当たることが無く履き心地が良好となる。 Further, the side surface equivalent portion 3 constituting the backing material has a shape that vertically covers the sole bottom portion of the backing material from the toe to the heel in the longitudinal direction so as to cover the heel, and the side edge of the toe equivalent portion 2 A joining edge S2 to be joined is formed. Further, a substantially cup-shaped cut portion 6 is formed at the heel rear end of the heel portion 5, and an heel outer peripheral portion of the sole heel portion 3a is formed in an arc shape along the outer shape of the heel. It can be made to conform three-dimensionally to the shape. The side surface equivalent portion 3 is formed with a joining edge S3 to be joined to the side edge of the vertically split sole heel portion 3a, and since there is no stitched portion at the back side of the side surface equivalent portion 3, the seam hits. There will be no comfort.
そして、このような爪先相当部２と側面相当部３と連接一体に構成される裏材1は、上記縦横分割、切り込み部が形成された裏材の接合縁(Ｓ１、Ｓ２、Ｓ３)における縫合部を縫糸７で千鳥縫い又はオーバーロック縫いにより縫合され、袋状の裏材が作られる。縫糸７は防水性を備えたポリエステル糸や撥水又は防水加工された糸を使用すると、縫糸を通して水の浸入が防止されるので好適である。作られた袋状の裏材は、縫合部の縫い目に防水テープ８が貼られて水の浸入が防止される。 The backing material 1 constructed integrally with the toe-corresponding portion 2 and the side surface-corresponding portion 3 is stitched at the joining edge (S1, S2, S3) of the backing material in which the vertical and horizontal divisions and the cut portions are formed. The portion is sewn with the sewing thread 7 by zigzag stitching or overlock stitching, and a bag-like backing material is made. For the sewing thread 7, it is preferable to use a waterproof polyester thread or a water-repellent or waterproofed thread because water can be prevented from entering through the sewing thread. The produced bag-like backing material is covered with a waterproof tape 8 at the seam of the stitched portion to prevent water from entering.
裏材1は図３に示すように表面からポリウレタン系熱可塑性エラストマーフィルム(ＴＰＵ)１ａ、トリコット生地１ｂ、スポンジ１ｃ、布帛１ｄの順に積層し、それぞれ公知の方法で接着したものである。このような積層された裏材であれば、ポリウレタン系熱可塑性エラストマーフィルム(ＴＰＵ)１ａがトリコット生地１ｂにより補強され、またスポンジ１ｃ、布帛１ｄによりクッション性及び断熱性が向上するので、特に防水機能を有した防寒靴には最適である。 As shown in FIG. 3, the backing 1 is formed by laminating a polyurethane-based thermoplastic elastomer film (TPU) 1a, a tricot fabric 1b, a sponge 1c, and a fabric 1d in this order, and bonding them by a known method. In such a laminated backing, the polyurethane-based thermoplastic elastomer film (TPU) 1a is reinforced by the tricot fabric 1b, and the cushioning and heat insulating properties are improved by the sponge 1c and the fabric 1d. It is most suitable for winter shoes with
防水テープ８は、ウレタン樹脂などからなる熱可塑性樹脂テープや裏材表面素材と同じ素材からなるポリウレタン系熱可塑性エラストマーテープが使用でき、縫い目を覆うように裏材のポリウレタン系熱可塑性エラストマーフィルムに熱融着させて貼り付けられる。このような防水テープ８は、伸縮性を有するため縫合部が破損されることがなく、また防水テープの貼付作業が容易で短時間ですみ、簡略化を図ることができる。以上のように本発明によれば、裏材の縫合部が従来に比べて少ないため、足あたりがなく履き心地が良好で、靴への水の浸入を確実に防止できる裏材を提供できる。 The waterproof tape 8 can be a thermoplastic resin tape made of urethane resin or the like, and a polyurethane thermoplastic elastomer tape made of the same material as the surface material of the backing, and heat can be applied to the polyurethane thermoplastic elastomer film of the backing so as to cover the seam. Fused and pasted. Such a waterproof tape 8 has stretchability so that the stitched portion is not damaged, and the waterproof tape can be easily applied in a short time and can be simplified. As described above, according to the present invention, since there are fewer stitched portions of the backing material as compared with the conventional one, it is possible to provide a backing material that has no foot contact and is comfortable to wear, and that can reliably prevent water from entering the shoe.
