Description

【０００１】
【発明の属する技術分野】
本発明は、ナイフ，包丁あるいは日本刀等の刃物から手を防護する暴漢制圧用等として最適な防刃手袋の製造方法と該方法に使用するためのミシンと該製造方法によって製造される防刃手袋に関する。
【０００２】
【従来の技術および発明が解決しようとする課題】
従来より格闘状態において刃物から手を防護するための防刃手袋は種々発明されている。古くは戦国時代にも使用されているように、鉄製の鎖を手の甲の表面に縫い付けたものが知られている。
【０００３】
一方、近年、化学繊維が飛躍的に発達し、アラミド繊維等のように摩耗あるいは破断強度等が極めて高い繊維が、出現している。
【０００４】
本出願人も、アラミド繊維を混入した生地を用いて、防刃用の手袋を開発し、市場に提供している。この防刃用手袋は、耐熱性能も高く、レスキュー隊員にも使用されているが、防刃性能においては、必ずしも、上述した鉄製の鎖を縫い付けたもの程には防刃性能は高くない。例えば、日本刀あるいは刺身包丁又はカッターナイフのような鋭利な刃物で切りつけられた場合には、条件によっては、多少とも切傷を受ける可能性が存在する。
【０００５】
勿論、鉄製、特にステンレス等の高強度のスチールを使用した鎖を手袋の周囲に配することによって防刃性能を高めることは、誰しも考えるところである。
【０００６】
しかしながら、鉄製の鎖の場合、基布に縫い付けようとすると、手縫いしか手法がなく、従って、量産性がないことから、価格的にも、極く特殊な分野でしか使用することができない程に高価になってしまうのが現状である。
【０００７】
また、鎖を平面的に編成した「鎖かたびら」状の手袋も食品加工用として存在するが、かかる場合には、鎖状のものを平面的に編成しなければならず、製造が非常に厄介で、それにも増して、手袋として柔軟性に乏しくなるため、耐刃性能自体は高いものの、その手袋をしたまま警棒等を把持して振り回しあるいは相手の衣類等を把持して技をかける等の暴漢制圧行動、あるいは各種スイッチ操作等を伴うバイクの運転等は不可能で、到底一般の警備に使用する手袋としては、使用できない。
【０００８】
ところで、最近、新聞紙上を毎日のように賑わす、刃物を使用した暴力事件が多発している。従って、職務上、嫌がおうにも対応せざるを得ない警察官にとっては、上述したようなアラミド繊維のみに防刃機能を求めた現在の手袋では、刃物を直に受け止めるには、甚だ不安がある。
【０００９】
本発明は、このような現況に鑑みおこなわれたもので、ステンレススチール等の鉄製あるいは炭素繊維等の耐刃機能の高い鎖を掌あるいは手の甲の適宜部位（最も刃を受けやすい部位）に配した防刃手袋を、大量生産可能な製造方法を提供することを第１の目的とし、さらにそのような製造方法を可能ならしめるミシンを提供することを第２の目的とし、またそのような製造方法に適した構造の手袋を提供するのを第３の目的とする。
【００１０】
【課題を解決するための手段】
本発明の上記第１の目的は、請求項１記載の防刃手袋によって解決される。つまり、本発明にかかる防刃手袋の製造方法は、耐刃機能を具備する繊維からなる生地で構成される第１の層材と、この第１の層材の内方に配設され耐刃機能の高い鎖を取着した第２の層材と、第２の層材の内方に肌触りの良い薄い生地からなる第３の層材を有する防刃用の手袋の製造方法であって、以下の（ａ）〜（ｅ）の工程を有する防刃手袋の製造方法。
【００１１】
（ａ）．少なくとも掌側のパーツが第１の層材で構成された掌側と手の甲側のパーツを手袋状に裏返した状態で縫製する。
【００１２】
（ｂ）．別の工程で、少なくとも掌側のパーツとなる上記第２の層材に鎖を取着する。
【００１３】
（ｃ）．上記（ｂ）の工程で鎖を取着した第２の層材の、該鎖を取着した反対側に、第３の層材を縫着する。
【００１４】
（ｄ）．上記（ａ）の工程で裏返した状態で手袋状に縫製した第１の層材に、上記（ｃ）の工程で得られた掌側に配置する第２の層材に第３の層材を取着したものを、鎖を取着した側が手袋として使用した状態において手袋の表面方に且つ第３の層材が掌の肌に接する位置になるよう、縫着する。
【００１５】
（ｅ）．上記（ｄ）の縫着が完了したものを裏返す。
【００１６】
しかして、このような構成からなる防刃手袋によれば、手袋を形成する多層状の層材の間に鎖を配置することができ、従って、刃物の刃を手で直接掴んでも、耐刃性能を具備する第１の層材と、鎖によって該刃を止めることができるため、例え日本刀等の鋭利なものであっても、安心して対応することができる。しかも、鎖は、多層になった各層材の間に配置されているため、手袋として非常に柔軟性を兼備し、バイクの運転を含む一般の警備にも何ら支承なく使用できる手袋となる。また、量産性にも優れた手袋となる。
【００１７】
また、本発明の上記第２の目的は、請求項５記載のミシンによって解決される。つまり、本発明にかかるミシンは、ミシン針が上下に昇降動作するとともに、生地等の対象物を運針に合わせて送るために、生地載置台表面から突出し送り動作する底部送り歯部と、上方から対象物を押圧し交互に上記底部送り歯部と同期して送り動作する左右一対の第１および第２の押さえ金具とを備え、延在する鎖の穴にミシン針を通して該鎖を生地に縫着するためのミシンであって、
上記左右一対の押さえ金具のうち、
第１の押さえ金具の底面に、鎖が通過し得るべく下方に開放した凹状の通過部を形成するとともに、この通過部の天井面に、鎖の穴に係止するための突起片を下方に向けて突設し、且つ、突起片から鎖の一ピッチに相当する距離だけ放して、ミシン針が通過するための針穴を形成し、
第２の押さえ金具の側面に、上記第１の押さえ金具の後方に位置するように、横突部を一体的に形成するとともに、この横突部の底面に、上記通過部と運針方向に一致するよう、鎖が通過し得るべく下方に開放した凹状の通過部を形成し、且つ、この通過部の天井面に、鎖の穴に係止するための突起片を、上記突起片と運針方向に一致するよう、下方に向けて突設したことを特徴とする。
【００１８】
しかして、本発明にかかるミシンによれば、第１と第２の押さえ金具が鎖の空間（穴）を利用して交互に、該底部送り歯部と協動して、生地と該鎖が一体になるよう運針に合わせて送り動作をおこない、ミシン針が、鎖の穴を利用して、生地に該鎖を極めて効率よく縫着することができる。しかも、上述のように、第１の送り金具には突起片と針穴（この明細書において「ミシン針が貫通する穴」をいう）とのピッチが鎖のピッチに一致して設けられていることから、また、鎖は第１と第２の押さえ金具の各突起片で運針方向に張られた状態となるため、ミシン針は必ず鎖穴に挿通される。この結果、ミシン針が鎖に当接して折損するようなことは皆無となる。
【００１９】
また、本発明の上記第２の目的は、請求項７記載のミシンによっても解決される。つまり、本発明にかかるミシンは、ミシン針を上下に昇降動作させる昇降ロッドと、生地等の対象物を運針とタイミングを合わせて送るべく、生地載置台表面から突出し送り動作する底部送り歯部と、上方から対象物を押圧する押さえ金具と、ミシン針を昇降させる昇降ロッドを昇降自在に保持する保持部材を、上記鎖通過溝よりやや広い幅だけ、生地の送り方向に直交する方向に振らせる横振り機構とを備え、延在する鎖を跨ぐようにジグザク状にミシン糸を掛けることによって該鎖を生地に縫着するためのミシンであって、
上記押さえ金具が、底面に、中央に鎖を長手方向に通過させる鎖通過溝と、該鎖通過溝の両側に左右に対峙して生地を押圧する押さえ面を備え、上記横振り機構が、鎖通過溝の中心を中心に生地の送り方向に直交する方向に均等幅だけ両側にミシン針を振らせるよう構成されていることを特徴とする。
【００２０】
しかして、本発明にかかるミシンによれば、押さえ金具の鎖通過溝を鎖が通過してゆくと、その鎖通過溝の中心に中心に横振り機構が保持部材を生地の送り方向に直交する方向に均等幅だけ所定寸法両側に振らせる結果、該保持部材に保持されている昇降ロッドが振られて、ミシン針が、延在する鎖を跨ぐようにジグザク状にミシン糸を掛ける。この結果、第２の層材に鎖を確実に縫着することができる。しかも、このミシンによれば、平面視において鎖が第２の層材上で鋭角に屈曲されて配置していても、簡単にその鎖を第２の層材に確実に且つ効率良く縫着することが可能となる。
【００２１】
また、本発明の上記第３の目的は、請求項８記載の防刃手袋によって解決される。つまり、本発明にかかる防刃手袋は、少なくとも掌の部分が複数の層材を積層することによって形成された防刃用の手袋であって、
この積層が、耐刃機能を具備する繊維からなる生地で構成される第１の層材と、この第１の層材の内方に配設され耐刃機能の高い鎖を取着した第２の層材と、第２の層材の内方に肌触りの良い薄い生地からなる第３の層材で積層されていることを特徴とする。
【００２２】
しかして、このように構成された防刃手袋によると、手袋を形成する多層状の層材の間に鎖が配置されているため、刃物の刃を手で直接掴んでも、耐刃性能を具備する第１の層材と、鎖によって該刃を止めることができるため、例え日本刀等の鋭利なものを掴んでも、掴んだ手は全く切り傷を受けることはないため、安心して対応することができる。しかも、鎖は、多層になった各層材の間に配置されているため、手袋として非常に柔軟性を兼備し、バイクの運転を含む一般の警備にも何ら支承なく使用できる手袋となる。また、量産性にも優れた手袋となる。しかも、最も内方には、肌触りの良い第３の層材が配設されているため、極めて良好なはき心地が得られる。
【００２３】
【発明の実施の形態】
そして、上記請求項１記載の防刃手袋の製造方法において、請求項２に記載するように、鎖を第２の層材に取着する工程が、ミシンを使用して、鎖の空間部分にミシン針を挿通してミシン糸で取着（縫着）する工程であれば、最も確実に且つ単純に鎖を第２の層材に取着することができることになる。
【００２４】
また、上記請求項１記載の防刃手袋の製造方法において、請求項３に記載するように、鎖を第２の層材に取着する工程が、ミシンを使用して、該ミシンのミシン針が相対的に送られる鎖を跨ぐように交互に左右（両側）に振ることによって、該鎖を第２の層材に、該鎖を跨ぐようにミシン糸でジクザクに取着する工程であれば、鎖を第２の層材上に所望の自在の状態に配置しても、確実に且つ簡単に、取着することができることになる。
【００２５】
また、上記請求項１記載の防刃手袋の製造方法において、請求項４に記載するように、鎖を第２の層材に取着する工程が、ミシンを使用して、第２の層材を構成する生地に、伸縮性のある取着生地を、間に前記鎖を挟んで、引っ張った状態で該鎖の両側部を縫着しても、請求項２記載の場合と同様に実現できる。
【００２６】
そして、上記請求項５記載のミシンにおいて、請求項６に記載するように、少なくとも第２の押さえ金具の底面に、対象物を送り方向にスリップ無く送るための、鋸歯状の送り歯が形成されていると、対象物の厚みが厚いものであっても、円滑に対象物を運針に合致させて送ることが可能となる。
【００２７】
そして、上記請求項８記載の防刃手袋において、請求項９に記載するように、第１の層材の掌側の表面に、滑り止め機能を具備する第４の層材がさらに配設されていると、刃物等の金属部分を持った際にも滑ることがなく、従って切刃を鎖で受け止めた状態で保持できる点で、さらに優れた構成となる。
【００２８】
また、上記請求項８記載の防刃手袋において、請求項１０に記載するように、鎖が金属製の鎖であって、該鎖が、掌側で、各指の先端から手首側に渡って配設された主配置列鎖群と、これらの主配置列鎖群の各列の間に掌部分にのみ配置された補助配置鎖群から構成されていると、鎖の延設方向が指の長手方向と合致し、従って、鎖が関節の動きに合致して違和感無く屈曲（変化）するため、全体的に、通常の手袋とさほど変わらない柔軟性の高い手袋となる。しかも、一般に、人間工学的に、刃物を握るのは、該鎖の長手方向に直交する方向となるため、確実に鎖が手を保護する態様となる。
【００２９】
また、上記請求項８記載の防刃手袋において、請求項１１に記載するように、鎖が第２の層材を構成する生地に対して、ミシン糸によって直接縫着されていると、最も確実に鎖を第２の層材に取着することができ、しかも余分な取着のための生地が不要となるため、より違和感の少ない手袋となり、しかも直接ミシンで縫着すると安価に実施できる手袋となる。特に、上記ミシン糸がアラミド繊維等の耐刃性能の高い繊維であると、刃物によっても切断し難い構成となるため好ましい構成となる。
【００３０】
また、上記請求項８記載の防刃手袋において、請求項１２に記載するように、防刃手袋の手の甲側に、伸縮性を有する取着生地を配置し、間に前記鎖を挟んで、該取着生地を引っ張った状態で該鎖の両側を縫着することによって、該鎖を手の甲部分に横方向に複数条に配設すると、かかる場合には、特別なミシンがない場合にも、請求項６記載の防刃手袋を実現することができる。また、手の甲の防刃性能を具備した構成となる。
【００３１】
また、上記請求項８記載の防刃手袋において、請求項１３に記載するように、第１の層材を構成する生地が、アラミド繊維を織成あるいは編成したもので構成されていると、防刃性および柔軟性（屈曲性）の点で、さらには耐熱性の点においても、優れた構成となる。
【００３２】
【実施例】
以下、本願発明にかかる防刃手袋およびその製造方法と該方法を実施するためのミシンの一の実施例を図面を参照しながら具体的に説明する。
【００３３】
図１は本発明の一実施例にかかる防刃手袋の全体の外観構成を示す一部表面を切り欠いた手の甲側から見た図、図２は図１に示す防刃手袋の掌側から見た一部表面を切り欠いた図、図３は図１に示す手の甲側の手袋のパーツを示す分解図、図４は図２に示す掌側の手袋のパーツを示す分解図である。
【００３４】
図１〜図４に基づいて説明すると、図１，図２に図示する防刃手袋は、多層状に生地を縫着することによって構成されている。即ち、
図３に図示するように、手袋の手の甲の部分は、耐刃機能を具備する繊維、つまりこの実施例ではアラミド繊維を二重編みした生地からなる第１の層材１と、この第１の層材の内方に配設され耐刃機能の高い鎖を上記第１の層材１に取着し且つ表面が肌触りの良い薄い生地で構成される取着生地８とを有する。この取着生地８は、伸縮性を有し肌に当接する側が肌触りの良い薄い生地からなる３層構造のもので、中間層として約１〜２ｍｍ厚さのスポンジを挟んで両側にネット状の薄厚の伸縮性の編地が配置された３層一体（一枚）状の生地から構成されている。さらに、親指と人差し指との間に配置される、滑り止め機能と耐水機能を具備した第４の層材４を有する。この第４の層材は、アラミド繊維を粗に織成し生地の片面（表面）に発泡性の塩化ビニールをコーティングした素材を使用している。上記手の甲の部分の第１の層材１は、縫製後の使い易さ（指の動かし易さ）に鑑み、親指部分１Ａと、カウス部分１Ｂと、人差し指から小指までを含むその他のベース部分１Ｃの３つのパーツから構成されている。
【００３５】
また、上記取着生地８は、この実施例では、鎖の配置に対応して、手の甲の該甲の部分（特に、この実施例では「手の甲の指の関節部分」）のみ配設される大きさのもので構成されている。
【００３６】
一方、図４に図示するように、手袋の掌の部分は、耐刃機能を具備する繊維、つまりこの実施例ではアラミド繊維からなる第１の層材１０と、この第１の層材１０の内方（掌の肌に近い側）に配設され耐刃機能の高い鎖Ｒを取着する第２の層材２０と、この第２の層材２０のさらに内方（掌の肌に近い側）に配設され肌触りの良い薄い生地で構成される第３の層材３０とを有し、さらに、上記第１の層材１０の外方には、滑り止め機能と防水機能を備えた第４の層材４０を有し、従って、手袋の掌の部分は、全部で４層構造となっている。
【００３７】
上記第１の層材１０は、手の甲の部分の第１の層材１と生地的に全く同じもので構成されている。上記第２の層材２０は、本実施例では、鎖の配設で凹凸が生じることによる肌への違和感を無くすことから、やや厚めの具体的には２〜５ｍｍ厚程度（この実施例では４ｍｍ）のアラミド繊維が混入されたフェルト生地でよって構成されている。上記第３の層材３０は、肌触りに優れ且つ保温性の面でも優れている薄手の綿ニット生地が使用されている。上記第４の層材４０は、上記手の甲の部分の第４の層材４と全く同じ、アラミド繊維を粗に織成した生地の片面に発泡性の塩化ビニールがコーティングされた素材が使用されている。
【００３８】
また、パーツとしては、上記第１の層材１０は、中指部分１０Ａと薬指部分１０Ｂと、さらにカウス部分１０Ｃと、これらを除いたベース部分１０Ｄの４つのパーツから構成されている。上述のように、ベース部分１０Ｄから中指部分１０Ａと薬指部分１０Ｂを除いたのは、手袋に縫製した後に、人差し指と小指部分の両側面部分の掌との境界部分に縫合部分を位置させないように、つまり、比較的敏感な指の腹部分での縫合を避けて「はき心地」を良くするべく、このように人差し指と小指部分を別のパーツで構成している。また、上記第２および第３の層材２０，３０は、カウス部分２０Ｃ，３０Ｃとその他のベース部分２０Ｄ，３０Ｄが別のパーツとして構成されている。なお、上記第４の層材４０は、その機能からして、カウス部分は存在しない。
【００３９】
上記耐刃機能の高い鎖Ｒとして、本実施例では、耐刃機能の高さと共に防錆機能に鑑みてステンレス製の鎖が使用されている。この鎖の素線径は約１ｍｍで鎖のピッチは約４ｍｍ程度のものが使用されている。この素線径およびピッチを大きくすると、耐刃機能は向上するが、鎖部分の凹凸が激しくなって肌への違和感が生じるとともに、手の開閉動作の、円滑さが損なわれるため、本実施例では、耐刃機能と違和感及び使い易さの両方を考慮して、上記の鎖を採用している。
【００４０】
しかして、このような構成要素からなる防刃手袋は、以下のような工程１〜工程１３からなる方法によって、製造される。即ち、
まず、第１に、図３、図４に図示するような形状になるよう、各層材および取着生地を、各パーツに裁断する。次に、別々のパーツとして存在する以下のパーツについて、互いに縫合する前に、以下の作業がおこなわれる。つまり、手の甲の第１の層材１に、間に鎖Ｒを挟んで、取着生地８を縫着する（工程１）。この際、伸縮自在な取着生地８の伸縮性を利用して、つまり、鎖Ｒを挟んで縫着する際に、取着生地８をやや引張勝手にしながら縫着する。この結果、縫着後、この取着生地８の弾性作用によって、鎖Ｒは、第１の層材１にぴったり縫着され、その後の鎖Ｒの移動が拘束されることになる。図１に図示するように、この手の甲の表面から見て複数の線の「山形」状になった部分は、一般に手の屈曲性を向上させるために設けられた「シャーリング」と呼ばれるもので、この実施例ではこのシャリングを利用して該シャーリング部分の内方に鎖Ｒを配置している。
【００４１】
また、上記工程１とは別に、手の甲のベース部分１Ｃに、親指部分１Ａとカウス部分１Ｂを一体に縫合する（工程２）。
【００４２】
同様に、掌部分についても、上記工程１および２とは別に、上記第２の層材２０に図４に図示するように、鎖Ｒを取着する（工程３）。この鎖Ｒは、図４に図示するように、各指の先から手首までそれぞれ２条（２本）延びる主配置鎖群Ｒ１と、これら各主配置鎖群Ｒ１の間にあって、指の股の部分から手首までの掌部分のみ配置される補助配置鎖群Ｒ２に大別できる。また、上記鎖Ｒの構成に代えて、図９に図示するように、掌全体を１本の鎖Ｒを連続して配置してもよく、かかる場合には、鎖Ｒが１本であるため、部品点数が減少するとともに鎖Ｒが１本であることから鎖取付作業に中断が無くなり、部品の管理と作業性の向上が期待できる。
【００４３】
ところで、鎖Ｒの層材（生地）２０への取着手法としては、図５に図示するように、ミシンで、鎖Ｒの各穴（空間）５０にミシン針を順次挿通させて、ミシン糸Ｓで鎖Ｒの一こまづつ縫着する。この手法では、図７に図示するような左右一対の押さえ金具１０１，１０２を具備したミシンを使用する。つまり、ミシンは、厚地縫製用の、押さえ金具が一対（１組）配設された市販の工業用ミシンの、この各押さえ金具部分を、図７に図示するものに交換して、鎖付け専用ミシンとしたものである。つまり、この市販の工業用ミシンは、図示しないが、ミシン針が上下に昇降動作するとともに、縫合対象である厚手の生地をも運針に合わせて確実に送ることができるように、生地載置台表面に送り動作する送り歯部が突出し、且つ上方から対象物を押圧し交互に送り動作する左右一対の第１および第２の押さえ金具を備えている。この市販の工業用ミシンを用い、その左右一対の第１および第２の押さえ金具を、図７に図示する第１及び第２の押さえ金具１０１，１０２と交換して、鎖を生地に縫着可能な専用ミシンとしたものである。この第１の押さえ金具１０１は、その底面１０１ａに、鎖Ｒが通過し得る下方に開放した凹状の通過部１０１ｂが形成されるとともに、この通過部１０１ｂの天井面１０１ｃに、鎖Ｒの穴５０に係止するための先端（下端）で細くなった円錐状の突起片１０１ｄが下方に向けて突設され、且つ、突起片１０１ｄから鎖の一ピッチＰに相当する距離Ｌだけ離して、ミシン針Ｎが通過するための針穴１０１ｅが形成されている。また、上記第２の押さえ金具１０２の側面１０２ｂには、上記第１の押さえ金具１０１側の後方に位置するように、横突部１０２ｃが形成されるとともに、この横突部１０２ｃの底面１０２ｄに、上記通過部１０１ｂと運針方向（図７（ｂ）において矢印Ｘ参照）において中心が一致するよう、鎖が通過し得る下方に開放した凹状の通過部１０２ｅが形成されている。そして、この第２の押さえ金具１０２の通過部１０２ｅの天井面に、鎖Ｒの穴５０に係止するための突起片１０２ｆが、上記突起片１０１ｄと運針方向（図７（ｂ）において矢印Ｘ参照）に一致するように、下方を向けて突設されている。また、上記第２の押さえ金具１０２の底面１０２ｄには、厚手の生地をスリップすることなく送るべく、鋸歯状の送り歯１０２ｇが形成されている。
【００４４】
また、この第１と第２の押さえ金具１０１，１０２は、ミシンからの駆動によって、ミシン針Ｎの昇降動作にタイミングをとって、交互に、つまり、一方の押さえ金具が上昇しているときには他方の押さえ金具が下方に位置して生地およびその上の鎖を上方から下方に押圧するよう作動する。そして、ミシン針Ｎとの関係においては、第１の押さえ金具１０１が下方に位置しているときに、ミシン針Ｎが降下して、該第１の押さえ金具１０１によって、生地と一体的に押さ付けている鎖Ｒの穴５０に該ミシン針Ｎに突き刺さって縫い付け、再び上昇するよう動作する。
【００４５】
鎖Ｒの別の取着手法としては、図６に図示するように、鎖Ｒを取着すべき第２の層材２０と、伸縮性のある薄い取着生地１８の間に鎖Ｒを挟んで、該鎖Ｒの動きを規制するよう少なくとも該鎖Ｒの両側を、ミシンで縫着することによっておこなってもよい。
【００４６】
さらに、鎖Ｒの別の取着手法としては、鎖Ｒ側から見ると図８（ａ）に図示するように、またその裏側から見ると図８（ｂ）に図示するように、鎖Ｒを取着すべき第２の層材２０に対して、該鎖Ｒを跨ぐようにミシン糸Ｓでジクザクに上から第２の層材２０に縫着してもよい。この手法には、図１０（ｂ）に図示するような底面を有し、下方の送り動作に同期して昇降する押さえ金具２０１と、図１０（ａ）に図示するような横振り機構Ｍを具備したミシンを使用する。つまり、このミシンは、厚地縫製用の、図示しない針棒を摺動自在に保持する保持部材が、連結ロッド２１４によって図１０（ａ）において左右（矢印Ｔ参照）に振られるとともに、押さえ金具２０１が下端に連結された第３揺動腕２１１によって昇降させられるよう構成された市販の工業用ミシンを改良したものを用いる。つまり、この工業用ミシンの押さえ金具２０１を、図１０（ｂ）に底面が図示するものに、また横振り機構Ｍのカム２０４を、上記押さえ金具２０１の鎖通過溝２０１ａの幅方向の中心に対して両側に均等の振り幅で且つ全体の振り幅が鎖の幅以上の振り寸法を有するものに交換した、鎖付け専用ミシンが用いられる。このミシンは、図示しないが、針が上下に昇降動作するとともに、縫合対象である厚手の生地を運針に合わせて確実に送ることができるように、生地載置台表面に送り動作する送り歯部が突出している。上記押さえ金具２０１は、その底面２０１A に、鎖Ｒが生地の送り方向に通過し得る下方に開放した凹状の鎖通過溝２０１a が形成されるとともに、この鎖通過溝２０１a の両側に、生地押圧する押さえ面２０１bが該鎖通過溝２０１a より下方（生地方）に突出するよう左右に対峙して形成されている。そして、この押さえ面２０１b の底面には、生地との接触抵抗を少なくして円滑な縫製がおこなえるようテフロン層が付着されている。
【００４７】
また、この押さえ金具２０１には、生地の送り方向に直交する方向に長くなった針穴２０１c が形成され、ミシン針Ｎが下方に通過し得るよう構成されている。つまり、この針穴２０１ｃの中央は、鎖通過溝２０１a 内に位置し、両端部は、上記押さえ面２０１b 部分に形成されている。しかし、この構成に代えて、押さえ面２０１b のある両側部にそれぞれ各１つの針穴を一対設けてもよく、かかる場合には、鎖通過溝２０１a が生地の送り方向（鎖通過方向）に連続した溝となり、鎖の通過がより円滑になる点で好ましい実施例となる。
【００４８】
また、この押さえ金具２０１は、上記第３揺動腕２１１の揺動動作によるその先端部分の昇降動作によって、ミシン針Ｎの昇降動作にタイミングをとって、上下に昇降する。つまり、ミシン針Ｎが下降するときには対象物を上方から押圧するように下降し、ミシン針Ｎが上方に位置しているときには、対象物からやや上昇し、対象物が上記生地載置台表面の送り歯部によって、ミシン針Ｎに対して相対的に移動可能に構成されている。
【００４９】
この押さえ金具２０１の昇降機構およびミシンの横振り機構Ｍについてさらに説明すると、図１０に図示する横振り機構Ｍの頂部が緩い曲線になった三葉状のカム２０４の周面（周縁）には、カムフォロワー２０５が当接して、上記カム２０４がミシンの図示しない主軸からの駆動によって回転すると、カムフォロワー２０５が取着されている第１揺動腕２０６が軸２０７を中心に揺動する。この第１揺動腕２０６は、バネ２０８によって、矢印Ｆで示すようにカム２０４側に引っ張られ、カム２０とカムフォロワー２０５が常に当接するよう構成されている。そして、上記軸２０７の所定角度だけの回動（往復の回転動作）によって、該軸２０７に取着されている第４揺動腕２１３が揺動し、この揺動が連結ロッド２１４を介して、上記保持部材をその枢支軸を中心に生地の送り方向に対して直交する方向に、つまり左右に、揺動させる。また、ミシン針Ｎは、上記カム２０４のカム軸２０３を駆動している図示しない主軸によって、昇降させられる針棒（図示せず）の下端に取着されている。従って、上記二つの動作が複合することによって、ミシン針Ｎは、昇降するとともに各昇降毎に左右に揺動することになる。

一方、押さえ金具２０１を昇降させる上記第３揺動腕２１１は、第２揺動腕２０９が枢支軸２１０を中心に揺動することによって、枢支軸２１２を中心に揺動させられる。この第２揺動腕２０９と第３揺動腕２１１は、該第２揺動腕２０９の端部に取着されている突設部２０９ａが第３揺動腕２１１の端部に形成されている空間部２１１ａに係合することによって、第３揺動腕２１１から第２揺動腕２０９に揺動動作が伝達されるよう構成され、また、この第２揺動腕２０９は、図示しないミシンの主軸から動力が伝達されるよう構成されている。この結果、逆Ｌ字状の上記第３揺動腕２１１が枢支軸２１２を中心に揺動し、上記押さえ金具２０１が昇降させられる。
【００５１】
また、上記カム２０４が１回転する間に、上記第３揺動腕２１１は６回揺動動作をするような割合で両者駆動されている。
【００５２】
この結果、ミシン針Ｎが１回昇降する毎に、矢印Ｋ１，Ｋ２に示すように右あるいは左に、交互に、該ミシン針Ｎが揺動させられることになる。
【００５３】
この結果、図８（ａ）に図示するように、ミシン針Ｎが鎖Ｒを跨ぐように左右（生地の送り方向に直交する方向）に振られると、鎖Ｒを、その下方に位置する第２の層材２０に対して、該ミシン針Ｎに挿通されたミシン糸Ｓで、ジクザク状に取着（縫着）することが可能となる。しかも、ミシンによるこのような縫着によれば、図８あるいは図９に図示するように、指先部分のように、小さい曲率半径で曲げたような鎖Ｒの配置であっても、その曲率に容易に追随して、鎖Ｒを縫着することができ、従って、図９に図示するように、１本の鎖Ｒでもって、手袋の掌の部分（あるいは手の甲の部分）全体に縫着することが可能となる。
【００５４】
上記工程３の次に、図４に示す上記掌の第１の層材１０のベース部分１０Ｄに、中指１０Ａと薬指１０Ｂの中央部分を縫着する（工程４）。
【００５５】
さらに、上記掌の第１の層材１０の外方（表面方）に、上記第４の層材４０を一体になるよう縫合する。この際、図２あるいは図４に破線で示すように、両者が完全に一体になるようミシン掛けをおこなう（工程５）。
【００５６】
上記工程１〜工程５は、各工程間の前後関係を特定する必要はなく、各工程に時間的前後があっても、あるいは別のワークエリアで並行しておこなわれてもよい。
【００５７】
上記各パーツの縫着を含む上記各縫着等の作業が終了すると、以下の工程（作業）を行う。即ち、
中指１０Ａと薬指１０Ｂの中央部分を縫着したベース部分１０Ｄの手首側の端部に、カウス部分１０Ｃを一体になるよう縫着する（工程６）。
【００５８】
手の甲の第１の層材１と掌の第１の層材１０のカウス部分１Ｃ，１０Ｃの手首側の付け根部分から、親指の付け根部分を経て人差し指の先まで裏返した状態で縫合する（工程７）。
【００５９】
それとは別に、第２の層材２０のカウス部分２０Ｃに鎖Ｒをジクザク状に配した状態で縫着する。この実施例では、カウス部分２０Ｃに、図６に図示する上述した手法によって鎖Ｒを取着し、これに鎖Ｒが中央になるように第３の層材３０のカウス部分３０Ｃを一体に縫製する（工程８）。
【００６０】
また、上記工程６〜工程８とは別に、上記掌側の第２の層材２０と第３の層材３０の各ベース部分２０Ｄ，３０Ｄを、それぞれの形状が重なるような状態で、一枚状に縫合する（工程９）。
【００６１】
上記工程７〜９は、特に順番のない別の作業でおこない、従って並行に作業をおこなうこともできる。
【００６２】
上記一体に縫合したカウス部分２０Ｃ，３０Ｃを、上記第１の層材１と一部縫合した第１の層材１０側に、該カウス部分２０Ｃ，３０Ｃとベース部分２０Ｄ，３０Ｄが上下一体になるように縫合する。この縫合の際、第３の層材３０が内方（肌に当接する側）になるような状態で縫合をおこなう。且つ、第１の層材１０のベース部分１０Ｄと上記ベース部分２０Ｄ，３０Ｄは縫合しない。（工程１０）。
【００６３】
また、上記工程８〜工程１０の前後いずれかで、あるいは並行作業として、第４の層材４を、間に、鎖が鋏込まれるように、固定のためのミシン掛けを含めて、図１，図２に図示するように、第１の層材１，１０の各親指側と人差し指側の部分に、手袋の表側が上面となるように縫着する（工程１１）。従って、掌側に関して言えば、一部第４の層材４が、第４の層材４０と重複して縫合されることになる。
【００６４】
次に、裏返した状態、つまり肌に触れる側が上方を向いた状態で、手の甲と掌の第１の層材１，１０の、上記縫合が完了していない部位、つまり、人差し指の中指側から小指側の手首まで、縫合する（工程１２）。
【００６５】
そして、次に、第１の層材１，１０を手袋状に縫合したものと、第２と第３の層材２０，３０を縫合したものを、各指先同士を縫着する（工程１３）。従って、この縫着によって、第４の層材４，４０を表面に取着した第１の層材１，１０に、第２と第３の層材２０，３０を縫合したものが、手袋として使用する際に該第３の層材３０が肌に触れる状態に固定されることになる。但し、この状態では手袋は裏返った状態となっている。
【００６６】
この縫合が完了すると、手袋を裏返せば、つまり、第４の層材４，４０が表面になるように手袋を裏返せば、防刃手袋が完成する。
【００６７】
なお、図１、図２に図示する防刃手袋の場合のように、手首を締めるリストベルト９が取着される場合には、上記工程７以降で、リストベルト９の基端を上記カウス部分の基端に縫合するとともに、該リストベルト９の先端が位置する部位と、対応する該リストベルトの先端部分の内側に、ベルベット式ファスナーを一対縫着する。しかし、このリストベルト９は、手袋の手首部分の甲側と掌側の間に形成されるスリット部分が小さいとき、あるいはカウス部分の手首側への寸法が短いときには、不要の場合もある。
【００６８】
また、上記スリット部分となるところに、工程１２の次の工程以降で、革等によって縁取り（縁巻き，あるいは「パイピング」ともいう）をすると、高級感を醸し出すことができ、またこの部分の引き裂き強度が向上する。
【００６９】
そして、上述のような各工程を経て製造されたこの実施例にかかる防刃手袋は、鎖Ｒが上述のように、挿入されているために、例えば、日本刀を掌で掴んでも、切刃の部分は、掌の上記主配置鎖群Ｒ１および補助配置鎖群Ｒ２であるいはその上方のアラミド繊維からなる第１の層材１０によって、確実に止められる。特に、鎖Ｒが、親指と人差し指の側面に沿って配設され、且つこの表面に第４の層材４が配設されていることから、人間工学的に刃物を掴んだときに最も切傷を受けやすい部位でも、確実に切刃を止めることが可能となっている。
【００７０】
また、この実施例にかかる防刃手袋の場合、手の甲の該甲の部分に横方向に鎖が複数条配設されているため、且つ手の甲全体がアラミド繊維からなる第１の層材１で構成されているため、誤って刃物が当たっても、さほど大きな切傷を受けることはない。
【００７１】
また、カウス部分にジクザク状に鎖が配置されているため、仮に血管が表皮近くになる手首部分に切刃が当たっても、大きな切傷を受けることはない。
【００７２】
さらに、手の甲の部分に配設されている複数条の鎖は、上記スポンジを含む取着生地によって内方から覆われているため、肌に鎖の凹凸が伝わることがないため、極めて履き心地の良い防刃手袋となっている。
【００７３】
ところで、上記実施例では、第４の層材として、革を使用してもよく、また、手の甲側に関していえば、刃物を握るときに切刃に当接する可能性が少ないことから、履き心地と使い易さを向上させるため、その第１の層材１として、革を使用してもよい。
【００７４】
また、カウス部分には、伸縮性のゴム入りの編成生地（ゴム入りのゴム編地）を用いてもよい。
【００７５】
また、上記鎖は、ステンレス製のものに代えて、他の金属（例えば、チタン製あるいは炭素鋼又はアルミ製等）又は炭素繊維系の素材で成形した鎖であってもよい。
【００７６】
また、必要ならば、上記実施例において、手の甲の部分を、掌の部分のように、４層状に構成することもでき、またこの場合、鎖を掌に類して指の先から手首側まで延設しておいてもよいが、かかかる場合には、手を閉じたときに鎖が延び勝手になるため、この寸法に合せて鎖を配設するか、もしくはジクザクに鎖を配設することが望ましい。
【００７７】
あるいは、履き心地を多少犠牲にするのであれば、上記第１の層材１０を、第１の層材１のような一枚の手形形状にしても、実施することができる。
【００７８】
また、上記第３の層材３０を、手の甲側の最も内方に配設してもよい。
【００７９】
また、上記実施例の工程とは順序を変えておこうこともでき、例えば、各層材のカウス部分を予めベルト状に縫合しておいて、これをベース部分に取着するようにしても、実施できる。他の工程についても、製造に差し支えない範囲において種々工程を変えることができることは言うまでもない。
【００８０】
【発明の効果】
しかして、本願発明によれば、従来ものに比べて耐刃性の高い且つ使用に際し違和感のない使い易い防刃性手袋を、効率良く、且つ、安価に、大量に供給することができる。また、鎖を正確に所定位置に簡単に且つ迅速に固定することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a blade-proof glove that is most suitable for use as a thief for protecting hands from knives, knives, or blades such as a Japanese sword, a sewing machine for use in the method, and a blade-proof device manufactured by the method Regarding gloves.
[0002]
[Background Art and Problems to be Solved by the Invention]
Conventionally, various blade-proof gloves for protecting a hand from a blade in a fighting state have been invented. In the old days, as used in the Sengoku period, iron chains are sewn on the back of the hand.
[0003]
On the other hand, in recent years, chemical fibers have drastically developed, and fibers such as aramid fibers having extremely high wear or breaking strength have appeared.
[0004]
The present applicant has also developed a glove for blade prevention using a fabric mixed with aramid fiber and provides it to the market. This blade-proof glove has high heat resistance and is used by rescue members, but the blade-proof performance is not necessarily as high as that obtained by sewing the above-described iron chains. For example, when cut with a sharp blade such as a Japanese sword, a sashimi knife, or a cutter knife, there is a possibility of being slightly cut depending on conditions.
[0005]
Of course, anyone is thinking of improving the blade-proof performance by arranging a chain made of high strength steel such as iron, particularly stainless steel, around the glove.
[0006]
However, in the case of an iron chain, when trying to sew to the base fabric, there is only a method of hand-sewing, and therefore, there is no mass productivity, so that it can be used only in very special fields from a price point of view. It is currently expensive.
[0007]
In addition, “chains of chain” gloves with flatly knitted chains also exist for food processing, but in such a case, the chain must be knitted flatly and manufacturing is very troublesome. In addition to this, since it becomes less flexible as a glove, the blade resistance itself is high, but with a glove, gripping a baton etc. and swinging or gripping the opponent's clothing etc. It is not possible to use a glove that is used for general security, because it is impossible to suppress a motor or drive a motorcycle with various switch operations.
[0008]
By the way, recently, violent incidents using cutlery, which thrive on newspapers every day, have occurred frequently. Therefore, for police officers who have no choice but to deal with dislikes in their duties, the current glove that requires a blade-proof function only for aramid fibers as described above is very anxious to accept the blade directly. There is.
[0009]
The present invention has been made in view of such a current situation, and is made by providing a chain having a high blade-resistant function, such as iron or carbon fiber, such as stainless steel, at an appropriate part of the palm or the back of the hand (the part most susceptible to the blade). A first object is to provide a manufacturing method capable of mass-producing blade gloves, and a second object is to provide a sewing machine that enables such a manufacturing method. A third object is to provide a glove having a suitable structure.
[0010]
[Means for Solving the Problems]
The first object of the present invention is solved by a blade-proof glove according to claim 1. That is, the method for manufacturing a blade-proof glove according to the present invention includes a first layer material composed of a fabric made of fibers having a blade-resistant function, and a blade-resistant function disposed inside the first layer material. A method for producing a glove for blade prevention having a second layer material with a high chain attached and a third layer material made of a thin fabric that is soft to the inside of the second layer material, The manufacturing method of the blade-proof glove which has the process of (a)-(e).
[0011]
(A). At least the palm side parts are sewn in a state in which the palm side parts and the back side parts made up of the first layer material are turned over like gloves.
[0012]
(B). In a separate step, a chain is attached to the second layer material which is at least a palm side part.
[0013]
(C). A third layer material is sewn on the opposite side of the second layer material to which the chain is attached in the step (b).
[0014]
(D). A third layer material is applied to the second layer material arranged on the palm side obtained in the step (c) on the first layer material sewn in a glove shape in the state of being turned upside down in the step (a). The attached material is sewn so that the side to which the chain is attached is used as a glove so that the third layer material is in contact with the palm skin in the surface direction of the glove.
[0015]
(E). Turn over the item (d) that has been sewn.
[0016]
Therefore, according to the blade-proof glove having such a configuration, a chain can be disposed between the multilayered layers forming the glove, and therefore even if the blade of the blade is directly gripped by hand, the blade-proof performance Since the blade can be stopped by the first layer material having a chain and a chain, even a sharp object such as a Japanese sword can be handled with peace of mind. Moreover, since the chain is disposed between the respective layered materials, the glove is extremely flexible as a glove and can be used without any support for general security including driving a motorcycle. Moreover, it becomes a glove excellent in mass productivity.
[0017]
The second object of the present invention is solved by the sewing machine according to claim 5. That is, in the sewing machine according to the present invention, the sewing needle moves up and down, and in order to feed an object such as a cloth along with the needle movement, a bottom feed dog part that protrudes from the cloth placing table surface and performs a feeding operation, and A pair of left and right first and second presser fittings that press the object and alternately feed in synchronization with the bottom feed dog portion, and sew the chain to the fabric through a sewing machine needle in the extending chain hole. A sewing machine for wearing,
Of the pair of left and right holding brackets,
On the bottom surface of the first presser fitting, a concave passage portion that is opened downward so that the chain can pass is formed, and a projecting piece for engaging with the hole of the chain is formed downward on the ceiling surface of the passage portion. Projecting toward and projecting from the projection piece by a distance corresponding to one pitch of the chain to form a needle hole for the sewing needle to pass through,
A lateral protrusion is integrally formed on the side surface of the second pressing metal so as to be located behind the first pressing metal, and coincides with the passing part and the direction of needle movement on the bottom surface of the horizontal protrusion. And forming a concave passage portion that opens downward so that the chain can pass through, and a projection piece for engaging with a hole in the chain on the ceiling surface of the passage portion. It is characterized by projecting downward so as to match.
[0018]
Thus, according to the sewing machine according to the present invention, the first and second presser fittings alternately cooperate with the bottom feed dog portion using the chain space (hole) so that the fabric and the chain are The feeding operation is performed in accordance with the needle movement so as to be integrated, and the sewing needle can sew the chain to the fabric very efficiently using the hole of the chain. Moreover, as described above, the first feed fitting is provided with the pitch between the protruding piece and the needle hole (referred to as “a hole through which the sewing machine needle passes” in this specification) matching the pitch of the chain. Therefore, the chain is stretched in the direction of movement by the protrusions of the first and second presser fittings, so that the sewing needle is always inserted through the chain hole. As a result, the sewing needle never comes into contact with the chain and breaks.
[0019]
The second object of the present invention is also solved by the sewing machine according to claim 7. That is, the sewing machine according to the present invention includes an elevating rod that moves the sewing needle up and down, a bottom feed dog that protrudes from the surface of the fabric placing table and feeds it so as to feed an object such as a fabric in time with the needle movement. The holding member that presses the object from above and the holding member that holds the lifting rod that raises and lowers the sewing needle so as to be raised and lowered are swung in a direction perpendicular to the feeding direction of the cloth by a width that is slightly wider than the chain passing groove. A sewing machine for sewing the chain to the fabric by hanging the sewing thread in a zigzag shape so as to straddle the extended chain,
The pressing metal fitting has a chain passing groove that allows the chain to pass in the longitudinal direction at the bottom, and a pressing surface that presses the fabric against the left and right sides on both sides of the chain passing groove. The sewing machine is characterized in that the sewing needles are swung on both sides by a uniform width in a direction orthogonal to the feeding direction of the cloth centering on the center of the passage groove.
[0020]
Thus, according to the sewing machine according to the present invention, when the chain passes through the chain passage groove of the presser fitting, the horizontal swing mechanism is orthogonal to the feeding direction of the cloth around the center of the chain passage groove. As a result of swinging in the direction by a uniform width to both sides of the predetermined dimension, the lifting rod held by the holding member is swung, and the sewing needle hangs the sewing thread in a zigzag shape so as to straddle the extended chain. As a result, the chain can be reliably sewn to the second layer material. Moreover, according to this sewing machine, even when the chain is bent and arranged at an acute angle on the second layer material in a plan view, the chain is easily and reliably sewn to the second layer material. It becomes possible.
[0021]
The third object of the present invention is solved by the blade-proof gloves according to claim 8. That is, the anti-blade glove according to the present invention is an anti-blade glove formed by laminating a plurality of layer materials at least on the palm part,
A first layer material composed of a fabric made of fibers having a blade-resistant function, and a second layer disposed on the inner side of the first layer material and attached with a chain having a high blade-resistant function It is characterized by being laminated with a material and a third layer material made of a thin fabric that is soft to the inside of the second layer material.
[0022]
Thus, according to the blade-proof glove configured in this way, since the chain is disposed between the multilayered layer materials forming the glove, even if the blade of the blade is directly gripped by hand, it has a blade-proof performance. Since the blade can be stopped by the first layer material and the chain, even if a sharp object such as a Japanese sword is gripped, the gripped hand will not be cut at all, so it can be handled with peace of mind. . Moreover, since the chain is disposed between the respective layered materials, the glove is extremely flexible as a glove and can be used without any support for general security including driving a motorcycle. Moreover, it becomes a glove excellent in mass productivity. In addition, since the third layer material that is comfortable to the touch is disposed most inwardly, extremely good wearing comfort can be obtained.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
And in the manufacturing method of the anti-blade glove according to claim 1, as described in claim 2, the step of attaching the chain to the second layer material uses a sewing machine to the space portion of the chain. If it is the process of inserting a sewing needle and attaching (sewing) with a sewing thread, the chain can be most reliably and simply attached to the second layer material.
[0024]
Moreover, in the manufacturing method of the anti-blade glove according to claim 1, as described in claim 3, the step of attaching the chain to the second layer material uses a sewing machine, and the sewing needle of the sewing machine is used. If it is a process of attaching the chain to the second layer material by alternatingly swinging left and right (both sides) so as to straddle the relatively fed chain, and a zigzag with a sewing thread so as to straddle the chain Even if the chain is arranged on the second layer material in a desired free state, it can be surely and easily attached.
[0025]
Moreover, in the manufacturing method of the anti-blade glove according to claim 1, the step of attaching the chain to the second layer material as described in claim 4 is performed by using a sewing machine. Even if both sides of the chain are sewn in a stretched state with a stretchable attachment fabric sandwiched between the fabrics constituting the fabric, it can be realized as in the case of claim 2 .
[0026]
In the sewing machine according to the fifth aspect, as described in the sixth aspect, a sawtooth feed dog is formed on at least the bottom surface of the second presser fitting for feeding the object without slipping in the feed direction. In this case, even if the object is thick, it is possible to smoothly send the object so as to match the hand movement.
[0027]
In the blade-protective glove according to claim 8, as described in claim 9, a fourth layer material having a non-slip function is further disposed on the palm-side surface of the first layer material. In this case, the structure is further improved in that it does not slip even when a metal part such as a blade is held, and therefore the cutting blade can be held in a state where it is received by a chain.
[0028]
Further, in the blade-protective glove according to claim 8, the chain is a metal chain, and the chain is on the palm side from the tip of each finger to the wrist side. When the main arrangement row chain group is arranged and the auxiliary arrangement chain group arranged only in the palm portion between each row of these main arrangement row chain groups, the extending direction of the chain is a finger Since it matches the longitudinal direction, and therefore the chain matches the movement of the joint and bends (changes) without a sense of incongruity, the overall glove is a highly flexible glove that is not much different from a normal glove. Moreover, in general, the ergonomically grasping the blade is in a direction perpendicular to the longitudinal direction of the chain, so that the chain reliably protects the hand.
[0029]
Further, in the blade-proof glove according to claim 8, when the chain is sewn directly to the fabric constituting the second layer material by the sewing thread as described in claim 11, it is most certain. The chain can be attached to the second layer material, and an extra fabric is not required, resulting in a less uncomfortable glove and a glove that can be carried out at a low cost by sewing directly with a sewing machine. It becomes. In particular, when the sewing thread is a fiber having high blade resistance such as an aramid fiber, it becomes a configuration that is difficult to cut even with a blade, which is a preferable configuration.
[0030]
Further, in the blade-protective glove according to claim 8, as described in claim 12, a stretchable attachment fabric is disposed on the back side of the hand of the blade-protective glove, and the chain is sandwiched therebetween, When the chain is sewn on both sides of the chain while the attachment fabric is pulled, the chain is arranged in a plurality of strips in the lateral direction on the back of the hand, and in such a case, even if there is no special sewing machine, The blade-proof glove of claim | item 6 is realizable. Moreover, it becomes the structure which comprised the anti-blade performance of the back of the hand.
[0031]
Further, in the blade-protective glove according to claim 8, when the fabric constituting the first layer material is composed of woven or knitted aramid fibers as described in claim 13, The structure is excellent in terms of cutting performance and flexibility (flexibility), and also in terms of heat resistance.

In the present embodiment, the second layer material 20 eliminates the uncomfortable feeling on the skin due to the unevenness caused by the arrangement of the chains. 4 mm) felt fabric mixed with aramid fibers. The third layer material 30 is made of a thin cotton knitted fabric that is excellent in touch and in terms of heat retention. The fourth layer material 40 is made of the same material as the fourth layer material 4 at the back of the hand, and is made of a material in which foamed vinyl chloride is coated on one side of a fabric in which aramid fibers are roughly woven. .
[0038]
In addition, as the parts, the first layer material 10 includes four parts, that is, a middle finger portion 10A, a ring finger portion 10B, a couse portion 10C, and a base portion 10D excluding these. As described above, the middle finger portion 10A and the ring finger portion 10B are removed from the base portion 10D so that the stitched portion is not positioned at the boundary portion between the index finger and the palms on both side portions of the little finger portion after sewing on the glove. In other words, the index finger and the little finger portion are made up of separate parts in this way in order to avoid “stitching” at the abdomen of the relatively sensitive finger and improve the “feel”. In addition, the second and third layer materials 20 and 30 are configured such that the couse portions 20C and 30C and the other base portions 20D and 30D are separate parts. In addition, the 4th layer material 40 does not have a Kaus part from the function.
[0039]
In the present embodiment, a stainless steel chain is used as the chain R having a high blade resistance function in view of the height of the blade resistance function and the rust prevention function. The strand has a strand diameter of about 1 mm and a chain pitch of about 4 mm. When this strand diameter and pitch are increased, the anti-blade function is improved, but the unevenness of the chain part becomes intense and the skin feels uncomfortable and the smoothness of the hand opening and closing operation is impaired. Considering both the anti-blade function and the uncomfortable feeling and ease of use, the above chain is adopted.
[0040]
Thus, the blade-proof glove composed of such components is manufactured by a method comprising the following steps 1 to 13. That is,
First, each layer material and attachment fabric are cut into each part so as to have a shape as shown in FIGS. 3 and 4. Next, for the following parts that exist as separate parts, the following work is performed before stitching together. That is, the attachment fabric 8 is sewn to the first layer material 1 on the back of the hand with the chain R interposed therebetween (step 1). At this time, using the stretchability of the stretchable attachment fabric 8, that is, when sewing with the chain R sandwiched, the attachment fabric 8 is sewn while slightly pulling. As a result, after sewing, the chain R is tightly sewn to the first layer material 1 by the elastic action of the attachment fabric 8, and the subsequent movement of the chain R is restricted. As shown in FIG. 1, a portion of a plurality of lines in the “mountain shape” as seen from the surface of the back of the hand is generally called “shearing” provided to improve the flexibility of the hand, In this embodiment, this shearing is used to place a chain R inside the shearing portion.
[0041]
Separately from step 1, the thumb portion 1A and the cous portion 1B are integrally stitched to the base portion 1C of the back of the hand (step 2).
[0042]
Similarly, with respect to the palm portion, a chain R is attached to the second layer material 20 as shown in FIG. 4 separately from the steps 1 and 2 (step 3). As shown in FIG. 4, the chain R is located between the main arrangement chain group R1 extending from the tip of each finger to the wrist (two), and between the main arrangement chain group R1. It can be roughly divided into auxiliary arrangement chain group R2 in which only the palm part from the part to the wrist is arranged. Further, instead of the structure of the chain R, as shown in FIG. 9, the entire palm may be arranged with one chain R continuously. In such a case, the chain R is one. Since the number of parts is reduced and the chain R is one, there is no interruption in the chain attaching work, and it can be expected that the parts are managed and the workability is improved.
[0043]
By the way, as shown in FIG. 5, the attaching method of the chain R to the layer material (fabric) 20 is performed by sequentially inserting a sewing needle into each hole (space) 50 of the chain R with a sewing machine. S sew one chain R at a time. In this method, a sewing machine having a pair of left and right presser fittings 101 and 102 as shown in FIG. 7 is used. In other words, the sewing machine is used only for chaining by replacing each holding metal part of a commercially available industrial sewing machine with a pair (one set) of holding metal parts for heavy-duty sewing, as shown in FIG. It is a sewing machine. In other words, this commercially available industrial sewing machine is not shown, but the surface of the fabric placing table is designed so that the sewing needle can be moved up and down, and the thick fabric to be stitched can be reliably fed along with the needle movement. And a pair of left and right first pressing metal fittings that alternately feed and press the object from above. Using this commercially available industrial sewing machine, the pair of left and right first and second presser fittings are replaced with the first and second presser fittings 101 and 102 shown in FIG. 7, and the chain is sewn to the fabric. It is a possible dedicated sewing machine. The first presser fitting 101 has a bottom passage 101a formed with a concave passage portion 101b opened downward through which the chain R can pass, and a hole 50 of the chain R formed on the ceiling surface 101c of the passage portion 101b. A conical protruding piece 101d that is thin at the tip (lower end) for locking to the sewing machine protrudes downward, and is separated from the protruding piece 101d by a distance L corresponding to one pitch P of the chain. A needle hole 101e through which the needle N passes is formed. In addition, a lateral protrusion 102c is formed on the side surface 102b of the second presser fitting 102 so as to be positioned rearward of the first presser fitting 101, and a bottom surface 102d of the lateral protrusion 102c is formed on the side face 102b. A concave passage 102e that opens downward and through which a chain can pass is formed so that the center coincides with the passage 101b in the direction of movement (see arrow X in FIG. 7B). Then, on the ceiling surface of the passing portion 102e of the second presser fitting 102, a protruding piece 102f for engaging with the hole 50 of the chain R is connected to the protruding piece 101d and the direction of movement (arrow X in FIG. 7B). So as to match the reference). Further, a sawtooth feed dog 102g is formed on the bottom surface 102d of the second presser fitting 102 so as to feed the thick fabric without slipping.
[0044]
Further, the first and second presser fittings 101 and 102 are driven alternately from the sewing machine, taking the timing of the raising and lowering operation of the sewing needle N, alternately, that is, when one presser fitting is raised, the other The presser fitting is positioned below and operates to press the fabric and the chain thereon from below. Then, in relation to the sewing needle N, when the first presser fitting 101 is positioned below, the sewing needle N descends and is pressed together with the fabric by the first presser fitting 101. The sewing machine needle N is pierced and sewn into the hole 50 of the chain R to which it is attached, and moves up again.
[0045]
As another attachment method of the chain R, as shown in FIG. 6, the chain R is sandwiched between the second layer material 20 to which the chain R is to be attached and the elastic thin attachment fabric 18. In order to regulate the movement of the chain R, at least both sides of the chain R may be sewn with a sewing machine.
[0046]
Further, as another attachment method of the chain R, as viewed from the side of the chain R, as shown in FIG. 8A, and as viewed from the back side, as illustrated in FIG. The second layer material 20 to be attached may be sewn to the second layer material 20 from above with a sewing thread S so as to straddle the chain R. In this method, there is provided a holding metal fitting 201 having a bottom surface as shown in FIG. 10B and moving up and down in synchronization with a downward feeding operation, and a horizontal swing mechanism M as shown in FIG. Use the provided sewing machine. That is, in this sewing machine, a holding member for slidably holding a needle bar (not shown) for sewing thick fabric is swung left and right (see arrow T) in FIG. Is an improved commercial industrial sewing machine configured to be moved up and down by the third swing arm 211 connected to the lower end. That is, the presser fitting 201 of this industrial sewing machine is the one whose bottom is shown in FIG. 10B, and the cam 204 of the horizontal swing mechanism M is centered in the width direction of the chain passing groove 201a of the presser fitting 201. On the other hand, a sewing machine exclusively used for chaining is used, which is replaced with one having a uniform swinging width on both sides and a swinging width that is equal to or larger than the width of the chain. Although this sewing machine is not shown in the drawing, a feed dog portion that feeds and moves on the surface of the fabric placing table is provided so that the needle can be moved up and down and the thick fabric to be stitched can be reliably fed according to the needle movement. It protrudes. The presser fitting 201 is formed with a concave chain passage groove 201a that opens downward on the bottom surface 201A through which the chain R can pass in the feeding direction of the cloth and presses the cloth on both sides of the chain passage groove 201a. The pressing surface 201b is formed so as to be opposed to the left and right so as to protrude downward (in the living district) from the chain passage groove 201a. A teflon layer is attached to the bottom surface of the pressing surface 201b so that the contact resistance with the fabric is reduced and smooth sewing can be performed.
[0047]
Further, the presser fitting 201 is formed with a needle hole 201c that is elongated in a direction orthogonal to the feeding direction of the fabric, so that the sewing needle N can pass downward. That is, the center of the needle hole 201c is located in the chain passage groove 201a, and both ends are formed on the pressing surface 201b. However, instead of this configuration, a pair of needle holes may be provided on both sides of the pressing surface 201b. In such a case, the chain passing groove 201a is continuous in the dough feeding direction (chain passing direction). This is a preferable embodiment in that the chain passes more smoothly.
[0048]
The presser fitting 201 is moved up and down at the timing of the lifting / lowering operation of the sewing needle N by the lifting / lowering operation of the tip portion thereof by the swinging motion of the third swinging arm 211. That is, when the sewing needle N descends, the object is lowered so as to press the object from above, and when the sewing needle N is located above, the object slightly rises from the object so that the object is fed to the surface of the cloth placing table. The tooth portion is configured to be movable relative to the sewing needle N.
[0049]
The lifting mechanism of the presser fitting 201 and the horizontal swing mechanism M of the sewing machine will be described further. On the peripheral surface (periphery) of the trilobal cam 204 in which the top of the horizontal swing mechanism M shown in FIG. When the cam follower 205 abuts and the cam 204 is rotated by driving the sewing machine from a main shaft (not shown), the first swing arm 206 to which the cam follower 205 is attached swings about the shaft 207. The first swing arm 206 is pulled by the spring 208 toward the cam 204 as indicated by an arrow F, so that the cam 20 and the cam follower 205 are always in contact with each other. Then, the rotation of the shaft 207 by a predetermined angle (reciprocating rotation) causes the fourth swing arm 213 attached to the shaft 207 to swing, and this swing is performed via the connecting rod 214. The holding member is swung in the direction orthogonal to the feeding direction of the dough, that is, right and left about the pivot shaft. The sewing needle N is attached to the lower end of a needle bar (not shown) that is moved up and down by a main shaft (not shown) that drives the cam shaft 203 of the cam 204. Therefore, by combining the above two operations, the sewing needle N moves up and down and swings to the left and right each time it moves up and down.
[0050]
On the other hand, the third swing arm 211 that raises and lowers the presser fitting 201 is swung around the pivot shaft 212 when the second swing arm 209 swings around the pivot shaft 210. The second swing arm 209 and the third swing arm 211 have a protruding portion 209 a attached to the end of the second swing arm 209 at the end of the third swing arm 211. The swinging motion is transmitted from the third swinging arm 211 to the second swinging arm 209 by engaging with the space portion 211a, and the second swinging arm 209 is a sewing machine (not shown). The power is transmitted from the main shaft. As a result, the inverted L-shaped third swing arm 211 swings about the pivot shaft 212, and the presser fitting 201 is moved up and down.
[0051]
Further, while the cam 204 makes one rotation, the third swing arm 211 is driven at such a ratio as to swing six times.
[0052]
As a result, every time the sewing needle N moves up and down once, the sewing needle N is swung alternately to the right or left as indicated by arrows K1 and K2.
[0053]
As a result, as shown in FIG. 8A, when the sewing needle N is swung left and right (in a direction orthogonal to the feeding direction of the cloth) so as to straddle the chain R, the chain R is located below the first one. The second layer material 20 can be attached (sewn) in a zigzag shape with the sewing thread S inserted through the sewing needle N. Moreover, according to such sewing by the sewing machine, even if the chain R is bent with a small radius of curvature, as shown in FIG. 8 or FIG. The chain R can be easily sewn and sewn, so that the entire palm part (or back part of the glove) is sewn with a single chain R as shown in FIG. It becomes possible.
[0054]
Following the step 3, the center portion of the middle finger 10A and the ring finger 10B is sewn to the base portion 10D of the palm first layer material 10 shown in FIG. 4 (step 4).
[0055]
Further, the fourth layer material 40 is sewn to the outside (surface side) of the first layer material 10 of the palm so as to be integrated. At this time, as shown by a broken line in FIG. 2 or FIG. 4, sewing is performed so that the two are completely integrated (step 5).
[0056]
The steps 1 to 5 do not have to specify the front-rear relationship between the steps, and may be performed in parallel in different work areas, even if each step has a temporal order.
[0057]
When the operations such as sewing, including the sewing of the parts, are completed, the following steps (work) are performed. That is,
The couse part 10C is sewn to the end part on the wrist side of the base part 10D where the middle parts of the middle finger 10A and the ring finger 10B are sewn (step 6).
[0058]
The first layer material 1 of the back of the hand and the first layer material 10 of the palm are stitched in a state where the wrist portions of the couse portions 1C and 10C are turned upside down through the root portion of the thumb to the tip of the index finger (step 7). ).
[0059]
Separately, the second layer material 20 is sewn in a state in which the chains R are arranged in a zigzag shape on the cous portion 20C of the second layer material 20. In this embodiment, the chain R is attached to the cous part 20C by the above-described method shown in FIG. 6, and the cous part 30C of the third layer material 30 is integrally sewn so that the chain R is in the center. (Step 8).
[0060]
Further, apart from the above steps 6 to 8, the base portions 20D and 30D of the palm-side second layer material 20 and the third layer material 30 are placed in a state where the respective shapes overlap each other. (Step 9).
[0061]
The above steps 7 to 9 are performed in a separate operation that is not particularly in order, and therefore, the operations can be performed in parallel.
[0062]
The cous portions 20C and 30C and the base portions 20D and 30D are integrated vertically on the side of the first layer material 10 partially sewn with the integrally sewn cous portions 20C and 30C. Suture. At the time of this stitching, the stitching is performed in a state where the third layer material 30 is inward (side to be in contact with the skin). Further, the base portion 10D of the first layer material 10 and the base portions 20D and 30D are not sewn. (Step 10).
[0063]
In addition, before or after Step 8 to Step 10 or as a parallel operation, the fourth layer material 4 includes a sewing machine for fixing so that a chain is inserted therebetween, as shown in FIG. 2, the first layer materials 1 and 10 are sewn to the portions on the thumb side and the index finger side so that the front side of the glove becomes the upper surface (step 11). Therefore, as far as the palm side is concerned, the fourth layer material 4 is partly stitched overlapping the fourth layer material 40.
[0064]
Next, in the state where the skin is turned over, that is, the side touching the skin is facing upward, the part of the first layer materials 1 and 10 of the back of the hand and the palm where the above stitching is not completed, that is, the little finger from the middle finger side of the index finger Suture to the wrist on the side (step 12).
[0065]
Then, the fingertips are sewn together between the first layer materials 1 and 10 stitched in a glove shape and the second and third layer materials 20 and 30 stitched together (step 13). . Therefore, by this sewing, the first layer materials 1 and 10 with the fourth layer materials 4 and 40 attached to the surface and the second and third layer materials 20 and 30 stitched together are used as gloves. In use, the third layer material 30 is fixed in a state of touching the skin. However, in this state, the gloves are turned over.
[0066]
When this stitching is completed, if the glove is turned over, that is, if the glove is turned over so that the fourth layer members 4 and 40 are on the surface, the blade-proof glove is completed.
[0067]
In the case where the wrist belt 9 for tightening the wrist is attached as in the case of the blade-proof gloves shown in FIGS. A pair of velvet fasteners are sewn to the portion where the tip of the wrist belt 9 is located and the inside of the corresponding tip of the wrist belt. However, the wrist belt 9 may be unnecessary when the slit portion formed between the back side and the palm side of the wrist portion of the glove is small or when the dimension of the cowse portion toward the wrist side is short.
[0068]
In addition, when the edge of the slit is trimmed with leather or the like after the step 12 (also referred to as edge winding or “piping”), a high-class feeling can be brought about, and the tearing of this portion can be achieved. Strength is improved.
[0069]
And the anti-blade glove according to this embodiment manufactured through the above-described steps has a cutting edge even if a Japanese sword is grasped with a palm because the chain R is inserted as described above. This portion is reliably stopped by the first layer material 10 made of aramid fibers in the main arrangement chain group R1 and the auxiliary arrangement chain group R2 of the palm or above. In particular, since the chain R is disposed along the side surfaces of the thumb and forefinger, and the fourth layer material 4 is disposed on the surface, the most incision occurs when the blade is ergonomically grasped. It is possible to reliably stop the cutting blade even in a part that is easily received.
[0070]
Further, in the case of the blade-proof glove according to this embodiment, a plurality of chains are arranged in the lateral direction on the back of the back of the hand, and the entire back of the hand is composed of the first layer material 1 made of aramid fiber. Therefore, even if the blade hits by mistake, it will not be damaged so much.
[0071]
In addition, since the chains are arranged in a zigzag shape at the cowse portion, even if the cutting blade hits the wrist portion where the blood vessel is close to the epidermis, it does not receive a large cut.
[0072]
Furthermore, since the multiple strands arranged on the back of the hand are covered from the inside by the attachment fabric including the sponge, the unevenness of the chains is not transmitted to the skin, so it is extremely comfortable to wear. It is a good blade-proof glove.
[0073]
By the way, in the said Example, leather may be used as a 4th layer material, and since there is little possibility that it will contact | abut a cutting blade when grasping a cutter as far as the back of the hand is concerned, In order to improve ease of use, leather may be used as the first layer material 1.
[0074]
Further, a stretchable rubber-knitted fabric (rubber-containing rubber knitted fabric) may be used for the cous part.
[0075]
The chain may be a chain formed of another metal (for example, titanium, carbon steel, aluminum, or the like) or a carbon fiber-based material instead of the stainless steel one.
[0076]
If necessary, in the above embodiment, the back part of the hand can be configured in four layers like the palm part. In this case, the chain is similar to the palm, from the tip of the finger to the wrist side. It may be extended, but in such a case, when the hand is closed, the chain will be extended, so the chain is arranged according to this dimension, or the zigzag is arranged. It is desirable.
[0077]
Alternatively, if the comfort is sacrificed to some extent, the first layer material 10 may be formed into a single bill shape like the first layer material 1.
[0078]
Further, the third layer material 30 may be disposed on the innermost side on the back side of the hand.
[0079]
In addition, the order of the steps of the above embodiment can be changed, for example, the cowse portion of each layer material is previously sewn into a belt shape, and this is attached to the base portion. Can be implemented. Needless to say, various processes can be changed within the range that does not interfere with manufacturing.
[0080]
【The invention's effect】
Thus, according to the present invention, it is possible to supply a large amount of blade-proof gloves that are higher in blade resistance than conventional ones and that are easy to use and have no sense of incongruity in use at low cost. In addition, the chain can be easily and quickly fixed accurately in place.
