Description

【技術分野】
【０００１】
本発明は眼鏡に係り、特に装着時に眼鏡と接する部分の皮膚に局所的にかかる装着ストレスを緩和させることができるように軽量化した眼鏡に関する。
【背景技術】
【０００２】
眼鏡を装着するときに、耳にかけるツルや鼻当部分の皮膚に力が加わり、ストレスが生じる。特に、長時間にわたる装着や激しい運動などによって装着ストレスは耐え難いものになる。眼鏡の装着ストレスを減らす有効な方法の一つは、眼鏡（サングラスを含む）の軽量化である。これまで様々な軽量化の努力がなされてきたが、より一層の軽量化を行うには、眼鏡の形状の大幅な変更と装着方法の工夫が必要である。
【０００３】
このような課題を考慮して装着方法を工夫し、粘着剤を用いて眼鏡を直接顔面の皮膚に貼り付けるアイデアは既に出願されている（例えば、特許文献１、特許文献２参照）。しかし、粘着剤を用いて直接眼鏡を顔面に貼り付ける場合、装着位置の微調整や眼鏡の掛け外しを繰り返すことによって粘着面が汗や皮脂で汚れ、粘着力が急速に低下する。そのため特許文献２では一時的な装着に限定している。
【０００４】
また、鼻の皮膚に磁性体を貼り付け、これに鼻あてに取り付けた磁石を付着させることによって眼鏡のずり落ちを防止させるアイデアが既に出願されている（例えば特許文献３）。しかし、この眼鏡は、鼻を挟み込むようにして眼鏡を固定する鼻当部分を用いるから、装着時に鼻当部分が当る鼻部分に装着ストレスが生じる。

【発明の開示】
【発明が解決しようとする課題】
【０００５】
本発明は、眼鏡を小型軽量化し、顔面へ装着するときに皮膚にかかる装着ストレスを緩和させることができる眼鏡を提供することを目的とする。
【課題を解決するための手段】
【０００６】
請求項１の発明は、レンズと、このレンズに設けた複数の脚部と、この脚部の先端側に設けた一方の着脱手段と、この一方の着脱手段と着脱可能な他方の着脱手段を備えた取付部材と、この取付部材に設けられた皮膚粘着面とを備えるものである。
【０００７】
また、請求項２の発明は、前記一方と他方の着脱手段が永久磁石と永久磁石、あるいは永久磁石と磁性体、あるいは磁性体と永久磁石である。
【０００８】
また、請求項３の発明は、左右の前記レンズを備え、これら左右のレンズを連結したものである。
【０００９】
また、請求項４の発明は、連結した前記左右のレンズを、前額側面、こめかみ、両眼の外側、頬などの皮膚に付着させた前記取付部材で支え、耳と鼻の皮膚に装着ストレスを加えないものである。
【００１０】
また、請求項５の発明は、前記一方と他方の着脱手段が並列磁石と並列磁石、あるいは並列磁石と磁性体、あるいは磁性体と並列磁石であり、前記並列磁石は、二個の永久磁石の極性を逆転させて並列させ、磁力線の拡散を防ぐものである。
【００１１】
また、請求項６の発明は、前記一方と他方の着脱手段が、前記脚部の先端側に設けた係止突起と前記取付部材に設けた突起係合部、もしくは前記脚部の先端側に設けた突起係止部と前記取付部材に設けた係止突起であり、前記係止突起と前記突起係止部が係脱可能なものである。
【００１２】
また、請求項７の発明は、前記一方と他方の着脱手段がねじ受部である。
【００１３】
また、請求項８の発明は、前記レンズ面の一部にフレネルレンズ様の段差を有する。
【発明の効果】
【００１４】
請求項１の構成によれば、眼の外側周囲の適宜位置に、粘着面により取付部材を取り付け、その取付部材の着脱手段と脚部の着脱手段とによりレンズを眼の前に装着する。この眼鏡は枠やツルがなく、軽量なものとなり、複数の取付部材が接するだけであるから、装着ストレスが少ない。このように剛体として一体性を持つ眼鏡を小型軽量化することができ、この小型軽量化によって皮膚と眼鏡との間に生ずる力が減少する。また、不要の場合は、着脱手段により、レンズと脚部のみを簡便に取り外することができる。
【００１５】
さらに取付部材と眼鏡本体を一体として使用することもできる。この場合、眼鏡の掛け外しを繰り返すことによって粘着面が汗や皮脂で汚れ、取付部材の皮膚面に対する粘着力が低下したときには、取付部材と脚部の着脱手段を利用して、新たな取付部材を眼鏡本体に付け替えることが可能である。
【００１６】
また、請求項２の構成によれば、着脱手段に磁石を用いることにより、掛け外しを非常に容易に行うことができる。
【００１７】
また、請求項３の構成によれば、左右のレンズを連結することにより、眼鏡の装着時の利便性が向上する。
【００１８】
そして、前額部や両眼の外側などの眼周囲の皮膚二カ所に、粘着面により取付部材を取り付け、その取付部材の着脱手段と脚部の着脱手段とにより連結した左右一対の薄型レンズを眼の前に装着する。二枚の薄型レンズの連結部分を鼻に接触させ、レンズの位置を安定させることができる。さらに、連結部分にスポンジ、ゴム、ゲル状物質などの緩衝材を付着させ、この緩衝材を介して鼻に接触させることもできる。通常、眼鏡の重量は１０から２０グラム程度であるが、例えば、１．５Ｄの屈折力を持つ凸レンズ、もしくは凹レンズを、十分な機械的強度と耐衝撃性を持つプラスチック素材を用いて薄型に成形した場合、取付部材を含む眼鏡の重量は数分の一程度まで軽量化することが可能である。この大幅な軽量化によって皮膚と眼鏡との間に生ずる力を減少させ、装着ストレスを緩和する。さらに、眼鏡と接する皮膚にシート状の取付部材をあてて保護することによって、装着ストレスを和らげる。眼鏡が不要の場合は、着脱手段により、連結したレンズと脚部のみを簡便に取り外しすることができる。さらに、前額部に取付部材を取り付けた場合は眼鏡を裏返しにして前額に装着させ、視界を妨げないように保持することも可能である。
【００１９】
また、請求項４の構成によれば、連結した左右のレンズからなる眼鏡本体に左右各二本ずつの脚部を介して四個の取付部材を取り付ける。この眼鏡を顔面に装着するときは、まず本体のレンズの連結部分に取り付けた鼻当を鼻に接触させ、眼鏡本体の位置を概略定める。次に左右一個ずつの取付部材を前額側面部又はこめかみの左右の皮膚二カ所に付着させ、眼鏡本体の位置を概略固定する。さらに残った左右一個ずつの取付部材を両眼の外側又は頬などの左右の皮膚二カ所に位置を選びながら付着させ、眼鏡本体の角度を微調整することによって、鼻当が鼻から浮いた状態で眼鏡本体の位置を最終的に固定する。このように請求項４の眼鏡では、眼鏡本体を前額側面やこめかみ、両眼の外側、頬などの皮膚に取り付けた四個の取付部材で支え、装着ストレスに高い感受性を有する耳や鼻の皮膚に持続的な力が加わらない状態で眼鏡位置を保持することができる。
【００２０】
現在、耳に掛けるツルを有する眼鏡が一般的であるが、従来からツルの先端部分をこめかみ部分や側頭部に押しつけることによって装着位置を保つ眼鏡が使用されてきた。最近このデザインを改変した耳に掛けるツルを持たない眼鏡が何種類か市販されている。しかし、これらの眼鏡は、鼻当で眼鏡本体の重量を概略支えるので、鼻の皮膚に加わる装着ストレスは減少しない。請求項４の眼鏡は取付部材の皮膚に対する面に粘着性を持たせ、取付部材と皮膚との付着力を増加させている。従って複数の取付部材を前額側面部やこめかみ、両眼の外側、頬などの皮膚に付着させるのみで眼鏡位置を安定に保持することが可能であり、耳だけでなく、鼻の皮膚にも持続的な装着ストレスが加わらない。この点、請求項４の眼鏡は、従来の耳に掛けるツルを持たない眼鏡とは全く異なる発明である。
【００２１】
また、請求項５の構成によれば、眼鏡脚部と取付部材との着脱手段に永久磁石を用いるが、二個の永久磁石の極性を逆転させて並列させて用いる。並列させたそれぞれの磁石から発する磁力線が遠距離ではお互いにキャンセルするため、磁力線の拡散を防ぎ、ペースメーカーなどの電子機器に悪影響を及ぼす可能性を減じることができる。
【００２２】
また、請求項６の構成によれば、眼鏡脚部と取付部材との着脱手段に係脱可能な係止突起と係止孔を用い、係止突起を左右横方向に設定することにより、左右一対の係止突起が回転中心となって眼鏡を上下方向に回転することができる。従って、眼鏡が不要になったら係止突起を中心に回転させて眼鏡を前額上に裏返した状態で保持することが容易にできる。
【００２３】
また、請求項７の構成によれば、眼鏡脚部と取付部材との着脱手段にねじを用いるが、ねじを左右横方向に設定することにより、左右一対のねじが回転中心となって眼鏡を上下方向に回転することができる。従って、眼鏡が不要になったらねじを中心に回転させて眼鏡を前額上に裏返した状態で保持することが容易にできる。
【００２４】
また、請求項８の構成によれば、レンズ面に段差を設けて厚みを減少させたレンズを用いる。屈折力が強く広い視野をカバーする大口径の凸レンズや凹レンズは厚みが増え、重量が増加する。一方、同心円状に多数の段差を持つフレネルレンズはシート状に薄くすることができるが、光学的な性能が良くない。請求項８の段差面を持つレンズでは良好な光学性能を必要とする視野の中心部分に小口径のレンズ部を配し、視野の周辺部分に何本かの段差面を設けたレンズを配することで、視野の中心部分の良好な光学性能と広い視野の両方を確保しながら、屈折力の強いレンズを軽量化できる。
【発明を実施するための最良の形態】
【００２５】
本発明における好適な実施の形態について、添付図面を参照しながら詳細に説明する。なお、以下に説明する実施の形態は、特許請求の範囲に記載された本発明の内容を限定するものではない。また、以下に説明される構成の全てが、本発明の必須要件であるとは限らない。各実施例では、従来とは異なる新規な眼鏡を採用することにより、従来にない眼鏡が得られ、その眼鏡について記述する。
【実施例１】
【００２６】
以下、本発明の実施例を添付図面を参照して説明する。図１〜図２は本発明の実施例１を示し、同図に示すように、眼鏡１は、左右のレンズ２，２の少なくとも一方を備え、そのレンズ２は、視力を矯正するレンズや光の透過率を調整するサングラスのレンズなどが用いられ、装着者の眼101に対応した形状を有する。尚、この例では、左右のレンズ２，２を別体で備える。
【００２７】
前記レンズ２の周囲側には、複数の脚部３が設けられ、この脚部３は、基端側をレンズ２に連結した線材４と、この線材４の先端に設けた永久磁石５とからなり、この一方の着脱手段である永久磁石５は、先端側に平面状の吸着面５Ｈを有する。そして、この例では、レンズ２に対し、脚部３は、装着者の眼101の外側部分の上下に対応した外側上下の二カ所と、鼻102の側面に対応した内側の下に対応した一カ所とに設けられている。
【００２８】
前記線材４は、合成樹脂製糸やワイヤなどの可撓性を有し、且つ所定の保形性を有するものが用いられ、レンズ２の縁側に一対の孔６，６Ａを近接して穿設し、前記線材４の基端をレンズ２の裏面側から、外側の孔６に挿通し、その挿通した基端をレンズ２の表面側から中央側の孔６Ａに挿通し、その裏面側に挿通した基端に、径大な抜止め部４Ａを形成してレンズ２に連結されている。また、線材４は、基端側４Ｋと先端側４Ｓとが略Ｌ字状に屈曲されており、屈曲された線材４の前記先端側４Ｓは、略前後方向（レンズ２の表裏方向）に向いている。
【００２９】
また、線材４の先端には、合成樹脂などにより、先端に向って拡大する拡大部７を設け、この拡大部７の先端面に前記永久磁石５が設けられ、この永久磁石５の先端に、平面状の前記吸着面５Ｈが配置されている。尚、前記永久磁石５は前記拡大部７内に埋設され、露出していない。そして、脚部３は、装着状態で、レンズ２と皮膚との間に間隔を保つ程度の保形性を備える。
【００３０】
また、前記眼鏡１は、前記脚部３に対応して、複数の取付部材11を備える。この取付部材11は、透明又は皮膚に近い色を有するシート12を略円形に形成し、そのシート12の表面中央に、他方の着脱手段である永久磁石13を設け、この永久磁石13はシート12内に埋設されるか、或いは表面に樹脂コーティングなどを施して外部に露出せずに設けられている。また、シート12の裏面は略平坦に形成され、その裏面に粘着剤を塗布するか粘着性の両面テープを貼り付けるなどして皮膚粘着面14を形成する。尚、永久磁石５，13は略円板状をなす。また、シート12は略円形で、最大寸法で１０ｍｍ〜２０ｍｍ程度である。
【００３１】
次に、前記眼鏡１の使用方法について説明すると、粘着面14により取付部材11を眼101の外側部分の二カ所と鼻102の側面の一カ所に接着する。そして、対応する脚部３の永久磁石５を、取付部材11の永久磁石13に吸着することにより、眼の前にレンズ２を配置し、眼鏡１を装着する。
【００３２】
また、レンズ２を使わない場合は、永久磁石５，13同士を引き離して、取付部材11を残してレンズ２を取り外す。この状態でも、小さな取付部材11は殆ど目立たず、そのままでも違和感が少なく、眼鏡１が不要な作業などを行うことができる。そして、スポーツや読書などで眼鏡１が必要になったら、レンズ２を再び装着することができる。
【００３３】
このように本実施例では、請求項１に対応して、レンズ２，２と、このレンズ２，２に設けた複数の脚部３，３と、この脚部３，３の先端側に設けた一方の着脱手段たる永久磁石５と、この永久磁石５と着脱可能な他方の着脱手段たる永久磁石13を備えた取付部材11と、この取付部材11に設けられた皮膚粘着面14とを備えるから、眼101の外側周囲の適宜位置に、粘着面14により取付部材11を複数取り付け、その取付部材11の永久磁石13と脚部３の永久磁石５とによりレンズ２を眼101の前に装着する。この眼鏡１は枠やツルがなく、軽量なものとなり、複数の取付部材11が接するだけであるから、装着ストレスが少ない。このように剛体として一体性を持つ眼鏡１を小型軽量化することができ、この小型軽量化によって皮膚と眼鏡１との間に生ずる力が減少する。また、不要の場合は、永久磁石５，13により、レンズ２と脚部３を簡便に取り外することができる。
【００３４】
また、取付部材11の取り付け部位については特に限定するものではないが、眼101の外側部分に二カ所と鼻102の側面に一カ所という選択が可能である。
【００３５】
また、本発明では皮膚に直接貼り付けるのは眼鏡・サングラスの本体ではなく取付部材11のみであり、また、装着位置の微調整や眼鏡１の掛け外しを磁石などの機能によって行うため、粘着力の低下は生じない。
【００３６】
本実施例では、一方と他方の着脱手段が永久磁石５，13であるから、掛け外しを非常に容易に行うことができる。尚、一方の着脱手段を永久磁石５とし、他方の着脱手段を前記永久磁石５が吸着する磁性体とし、この磁性体を前記取付部材11に設け、あるいは一方の着脱手段を前記永久磁石13が吸着する磁性体とし、この磁性体を前記脚部３に設け、他方の着脱手段を永久磁石13としてもよい。
【００３７】
上述したように、本実施例では、眼鏡の左右のレンズ２，２を分離し、それぞれのレンズ２，２に数本の脚部３を取り付け、この脚部３を介してレンズ２を眼101に装着させる。通常型の縁なし眼鏡のツルの両端を伸ばそうとすると、テコの原理でレンズ２の接合部に大きな力がかかるが、本発明のレンズ２と脚部３の接合部にかかる力は小さい。従ってレンズ２を薄くし、また脚部３を細く軽くして、一層軽量化することが可能である。
【００３８】
また、眼鏡１を装着させる部位の皮膚に、シート状の取付部材11を粘着剤によって貼り付け、皮膚を保護している。また、取付部材11と脚部３との取り付け部分には局所的な力が加わるが、取付部材11により皮膚の広い範囲に力が分散される。
【００３９】
本発明では、このように永久磁石13，５により着脱手段を構成したが、永久磁石５，13がペースメーカーなどの機器に悪影響を及ぼすと懸念される場合は、永久磁石の代わりに面ファスナーにより着脱手段を構成してもよい。この場合、雄型面ファスナーとこれに着脱自在に雌型面ファスナーを取付部材11又は脚部３に設ければよい。
【００４０】
また、表情の変化などによって皮膚の変位やゆがみが生ずるが、脚部３の一部にテグスなど柔軟に変形する線材４を設けて変位やゆがみを吸収することができる。
【実施例２】
【００４１】
図３及び図４は、本発明の実施例２を示し、上記実施例１と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例の眼鏡１は、レンズ２Ａが着色などされたサングラスを示している。また、装着状態でレンズ２Ａにより前記脚部３と取付部材11とが略隠れるように構成され、実施例１に比べてレンズ２Ａは大きく形成されている。また、脚部３は線材４の基端側４Ｋをレンズ２Ａの裏面に沿わせ、その基端側４Ｋを接着などにより固定している。尚、この例では、線材４の基端側４Ｋを小径な筒部材21に挿入して固定し、その筒部材21をレンズ２Ａの裏面に接着している。尚、レンズ２Ａは各種の方法で着色することができ、例えば、着色シートを接着したものでもよいし、或いはレンズ２Ａは、偏光レンズとしてもよい。
【００４２】
また、シート12の中央の突出部12Ａに前記永久磁石13を埋設し、これにより永久磁石13の位置が分かり易くなる。
【００４３】
このように本実施例では、眼鏡１は、レンズ２Ａが着色などされたサングラスであり、上記実施例１と同様な作用・効果を奏し、また、この例では、着色されたレンズ２Ａの裏面側に脚部３と取付部材11とが略隠れるから、前面側からは取付構造が視認されず、あたかもレンズ２Ａのみが単独で装着された外観となり、意匠的にも面白みに優れたものとなり、高い商品価値が得られる。
【実施例３】
【００４４】
図５は、本発明の実施例３を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では、レンズ２，２同士を紐などの連結部材31により連結している。
【００４５】
このように本実施例では、上記実施例１と同様な作用・効果を奏し、また、このように本実施例では、請求項３に対応して、左右のレンズ２，２を備え、これら左右のレンズ２，２を連結したから、眼鏡１の装着時及び格納時の利便性が向上する。例えば、連結する部材31を紐などの折曲可能な線状部材にすれば、左右のレンズ２，２の力学的な独立性が損なわれない。そして、左右のレンズ２，２を連結することにより眼鏡１の顔面への装着や格納が便利になる。
【実施例４】
【００４６】
図６は、本発明の実施例４を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では、レンズ２の上側で外側と内側に脚部３をそれぞれ設け、この脚部３Ａは、線材４の基端側４Ｋが上側に向き、眉103の上の額にまで延設されている。
【００４７】
したがって、眉103の上に取付部材11を接着し、その永久磁石５，13により取付部材11に脚部３を取り付け、このようにしてレンズ２の上側が脚部３により上方で固定されるため、脚部３によりレンズ２を吊下げた状態で装着することができ、安定性に優れたものとなる。
【実施例５】
【００４８】
図７〜図１０は、本発明の実施例５を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、眼鏡１は、二枚の薄型レンズ２，２を備え、そのレンズ２は、視力を矯正するレンズや光の透過率を調整するサングラスのレンズなどが用いられ、図７に示すように、装着者の眼101に対応した形状を有する。左右のレンズ２，２は連結部材31で連結される。なお、連結部材31は、略Ｕ字状に屈曲された、ワイヤなどの可撓性を有し、且つ所定の保形性を有する線材などからなり、Ｕ字状の底部で鼻102に接する部分には、スポンジやゴム、ゲル状物質などの緩衝材32を取り付けることができる。連結部材31は両端を屈曲させるか膨大部を設け、屈曲したあるいは膨大した連結部材31の両端をレンズ２の縁側裏面に付着させた合成樹脂33などに埋没させて、レンズ２に連結されている。
【００４９】
前記の連結したレンズ２の周囲側には、前記脚部３が設けられ、この脚部３は、基端側をレンズ２に連結した前記線材４と、この線材４の先端に設けた並列磁石５Ａ，５Ｂとからなる。この一方の着脱手段である並列磁石５Ａ，５Ｂは吸着面の磁石の極性が異なる。すなわち、並列磁石とは、永久磁石５Ａ，５Ｂを並べて配置してなり、一方の面において並列磁石５Ａ，５ＢはＳ極，Ｎ極又はＮ極，Ｓ極をなし、他方の面において並列磁石５Ａ，５ＢはＮ極，Ｓ極又はＳ極，Ｎ極をなす。
【００５０】
そして、この実施例５では、レンズ２に対し、脚部３は、装着者の左右の眼101の上側部分に対応した二カ所に設けられ、眼鏡１を吊った状態で装着可能とするものである。線材４は、ワイヤなどの可撓性を有し、且つ所定の保形性を有するものが用いられ、屈曲したあるいは膨大した線材４の先端をレンズ２の縁側に付着させた合成樹脂33などに埋没させて、レンズ２に連結されている。
【００５１】
また、線材４の先端には、吸着面の磁石の極性が異なる並列磁石５Ａ，５Ｂが取り付けられている。前記線材４には、その先端をかぎ状に屈曲した折返し部４Ｂを形成し、この折返し部４Ｂ内に並んで前記並列磁石５Ａ，５Ｂを配置し、これら折返し部４Ｂと前記並列磁石５Ａ，５Ｂとを、合成樹脂33Ａで固めて一体化し、図８（Ａ）に示すように、並列磁石５Ａ，５Ｂの吸着面は両面とも吸着面として機能するよう、露出され、前記合成樹脂33Ａはシート状に形成する。脚部３は、装着状態で、レンズ２，２と眼101との間に間隔を保つ程度の保形性を備える。
【００５２】
また、前記眼鏡１は、前記二個の脚部３に対応して、二個の取付部材11を備える。この取付部材11は、透明又は皮膚に近い色を有するシート12を略楕円形に形成し、そのシート12の表面に、他方の着脱手段である吸着面の磁石の極性が異なる並列磁石13Ａ，13Ｂが取り付けられている。この並列磁石13Ａ，13Ｂはシート12内に埋設されるか、或いは表面に貼り付けられている。また、シート12は皮膚面のカーブに合わせた曲面に形成されている。シート12の裏面には粘着剤を塗布するか、粘着性の両面テープを貼り付けるなどして皮膚粘着面14が形成されている。また、略楕円形のシート12の寸法は、短径と長径がそれぞれ１０ｍｍと２０ｍｍ程度である。尚、並列磁石５Ａ，５Ｂ及び並列磁石13Ａ，13Ｂは、上下方向に並設されている。
【００５３】
次に、前記眼鏡１の使用方法について説明すると、粘着面14により取付部材11を左右の眉103の上の前額104の皮膚二カ所に接着する。そして、対応する脚部３の並列磁石５Ａ，５Ｂを、取付部材11の並列磁石13Ａ，13Ｂに吸着することにより、眼101の前に連結したレンズ２，２を配置し、眼鏡１を装着する。このとき、脚部３の弾性により、左右のレンズ２，２を連結する連結部材31が直接、あるいは緩衝材32を介して鼻102に接し、レンズ２，２の位置が安定して保たれる。
【００５４】
また、眼鏡１を使わない場合は、並列磁石５Ａ，５Ｂと並列磁石13Ａ，13Ｂを引き離して、取付部材11を残して連結レンズ２，２を取り外す。この状態でも、小さな取付部材11は殆ど目立たず、そのままでも違和感が少なく、眼鏡１が不要な作業などを行うことができる。そして、読書などで眼鏡１が必要になったら、再び連結レンズ２，２を装着することができる。
【００５５】
さらに、図１０（Ｂ）に示すように、取り外した眼鏡１を裏返し、その状態で脚部３の並列磁石５Ａ，５Ｂを、取付部材11の並列磁石13Ｂ，13Ａに吸着させることにより前額104上に眼鏡１を保持し、視野を妨げない形で眼鏡１を装着し続けることも可能である。
【００５６】
このように本実施例では、請求項３に対応して、レンズ２と、このレンズ２に設けた脚部３と、この脚部３の先端側に設けた一方の着脱手段たる並列磁石５Ａ，５Ｂと、この並列磁石５Ａ，５Ｂと着脱可能な他方の着脱手段たる並列磁石13Ａ，13Ｂを備えた取付部材11と、この取付部材11に設けられた皮膚粘着面14とを備え、左右のレンズ２，２を備え、これら左右のレンズ２を連結したから、例えば眉103の上の前額104上の適宜位置に、粘着面14により取付部材11を二個取り付け、その取付部材11の並列磁石13Ａ，13Ｂと脚部３の並列磁石５Ａ，５Ｂとによりレンズ２，２を眼101の前に装着する。この眼鏡１は枠や耳に掛けるツルがなく、軽量なものとなる。また、皮膚には二個の取付部材11と、連結部材31が直接、あるいはスポンジやゴム、ゲル状物質などの緩衝材32を介して接するだけであるから、装着ストレスが少ない。眼鏡１を軽量化することによって皮膚と眼鏡１との間に生ずる力は減少する。また、眼鏡１が不要の場合は、並列磁石５Ａ，５Ｂと並列磁石13Ａ，13Ｂを引き離し、連結レンズ２，２のみを簡便に取り外することができる。または眼鏡１を裏返し、視野を妨げない前額上に装着させることもできる。
【００５７】
連結したレンズ２，２に取り付ける脚部３の数は特に限定するものではないが、装着の簡便性を考慮すると左右合わせて二本とするのが合理的である。また、取付部材11の取り付け部位についても特に限定するものではないが、本実施例に示すように、眼101の上側である前額104の二カ所、左右の眼101の外側部分の二カ所、あるいはこめかみ部分の二カ所などの選択が合理的である。
【００５８】
また、従来のように、粘着剤や粘着性の両面テープを用いて直接眼鏡を顔面に貼り付ける場合、装着位置の微調整や眼鏡のかけはずしを繰り返すことによって粘着面が汗や皮脂で汚れ、粘着力が急速に低下する。これに対して、本発明では皮膚に直接貼り付けるのは眼鏡・サングラスの本体ではなく取付部材11のみであり、また、眼鏡１の掛け外しを永久磁石などの吸着・引きはがしを何度繰り返しても吸着力が低下しない着脱手段によって行うため、粘着力の低下は生じない。また、予備の取付部材11を何組か用意しておけば、粘着力が低下したした場合に速やかに交換することができる。
【００５９】
また、本実施例では、一方と他方の着脱手段が並列磁石５Ａ，５Ｂと並列磁石13Ａ，13Ｂであるから、良好な固定状態が得られると共に、掛け外しを非常に容易に行うことができる。また、並列させたそれぞれの磁石から発する磁力線が遠距離ではお互いにキャンセルするため、磁力線の拡散を防ぎ、ペースメーカーなどの電子機器に悪影響を及ぼす可能性を減じることができる。尚、一方の着脱手段を並列磁石５Ａ，５Ｂとし、他方の着脱手段を前記並列磁石５Ａ，５Ｂが吸着する磁性体とし、この磁性体を前記取付部材11に設け、あるいは一方の着脱手段を前記並列磁石13Ａ，13Ｂが吸着する磁性体とし、この磁性体を前記脚部３に設け、他方の着脱手段を並列磁石13Ａ，13Ｂとしてもよい。
【００６０】
本実施例では磁力線の遠距離への拡散を防いだ並列磁石５Ａ，５Ｂと並列磁石13Ａ，13Ｂを用いたが、磁力線の拡散を気にしない場合は請求項２のように単独の永久磁石と永久磁石、または単独の永久磁石と磁性体、または磁性体と単独の永久磁石をそれぞれ脚部５と取付部材11に取り付け、着脱手段としてもよい。
【００６１】
本発明の眼鏡１は軽量化することができる。例えば、１．５Ｄの屈折力を持つ凸レンズ、もしくは凹レンズを、十分な機械的強度と耐衝撃性を持つプラスチック素材を用いて薄型に成形した場合、取付部材を含む眼鏡の重量は数グラム程度にすることが可能である。この軽量化によって皮膚と眼鏡１との間に生ずる力が減少する。また、眼鏡１と接する部分にシート状の取付部材１１をあてて皮膚を保護することによって装着ストレスをさらに緩和できる。
【００６２】
実施例５に示す本発明の眼鏡１は、眼鏡の装着ストレスを不快に感じながらも長時間の装着を余儀なくされている人のための眼鏡としての用途が考えられる。また、脚部３と取付部材11に取り付ける適切な着脱手段用いた場合は、眼鏡１を裏返しても脚部３を取付部材11に取り付けることが可能であり、この場合、視野を妨げない形で眼鏡１を前額104に装着させることができるので、頻繁な眼鏡の掛け外しを必要とする人のための眼鏡としての用途も考えられる。
【実施例６】
【００６３】
図１１〜図１２は、本発明の実施例６を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、同図は、一方と他方の着脱手段の変形例を示し、一方の着脱手段は、着脱手段本体34に設けた係止突起35又は突起係止部たる係止孔36であり、他方の着脱手段は、着脱手段本体34に設けた係止孔36又は係止突起35であり、前記係止孔36に前記係止突起35が弾発的に係脱する。例えば、一方の着脱手段は雄スナップリングであり、他方の着脱手段は雌スナップリングである。
【００６４】
このように本実施例では、請求項６に対応して、一方と他方の着脱手段が、脚部３の先端側に設けた係止突起35と取付部材11に設けた突起係止部たる係止孔36、もしくは前記脚部の先端側に設けた突起係止部たる係止孔36と取付部材11に設けた係止突起35であり、係止突起35と係止孔36が係脱可能であるから、係止突起35を左右横方向に設定することにより、左右一対の係止突起35が回転中心となって眼鏡１を上下方向に回転することができる。従って、眼鏡１が不要になったら係止孔36を中心に回転させて眼鏡１を前額104上に裏返した状態で保持することが容易にできる。
【実施例７】
【００６５】
図１３は、本発明の実施例７を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、同図は、一方と他方の着脱手段の変形例を示し、一方の着脱手段はねじ受部たる透孔37又はねじ受部たるねじ孔38であり、他方の着脱手段がねじ孔38又は透孔37であり、この透孔37に挿通したねじ39を前記ねじ孔38に螺合することにより、透孔37とねじ孔38を設けた脚部３と取付部材11とを着脱自在に構成している。尚、前記透孔37とねじ孔38は着脱手段本体34Ａに形成され、この着脱手段本体34Ａが脚部３と取付部材11に設けられている。尚、着脱手段本体34Ａは略筒状をなす。
【００６６】
このように本実施例では、請求項７に対応して、一方と他方の着脱手段がねじ受部である透孔37とねじ孔38であるから、ねじ39を用い、装着状態でねじ39の向きを左右横方向に設定するように構成することにより、左右一対のねじ39が回転中心となって眼鏡１を上下方向に回転することができる。従って、眼鏡１が不要になったらねじ39を中心に回転させて眼鏡１を前額104上に裏返した状態で保持することが容易にできる。
【実施例８】
【００６７】
図１４は、本発明の実施例８を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例の眼鏡１はサングラスとしての用途を持ち、左右のレンズ２Ａ，２Ａとその連結部材31Ａ、脚部３Ａ，３Ａが、合成樹脂製などからなるレンズシート41で形成されたものである（図１４参照）。このレンズシート41には、着色させたりハーフミラー機能や偏光フィルターとしての機能、反射防止機能などを与えることができる。連結部材31Ａの裏面には緩衝材32Ａが設けられ、脚部３Ａの裏面には前記並列磁石５Ａ，５Ｂが取り付けられている。略円状の形状を持つ取付部材11Ａには別の並列磁石13Ａ，13Ｂが取り付けられ、眼101の外側の皮膚二カ所に粘着面14で付着させてある。装着状態で眼鏡１により前記取付部材11Ａが略隠れるように構成されている。また、緩衝材32Ａは鼻に接し、眼鏡１の位置を安定化させている。
【００６８】
なお、本実施例８では並列磁石５Ａ，５Ｂ及び並列磁石13Ａ，13Ｂの各磁石間の距離を増加させた例を示している。このように必要に応じて並列させた磁石間の距離を増加させれば、磁力線の拡散範囲も増加するので、眼鏡１の装着を容易にすることができる。
【００６９】
本実施例では、眼鏡１は、レンズ２Ａ，２Ａが着色などされたサングラスであり、上記各実施例と同様な作用・効果を奏し、また、この例では、着色などされた眼鏡１の裏面側に取付部材11Ａが略隠れるから、前面側からは取付構造が視認されず、あたかも眼鏡１のみが単独で装着された外観となり、意匠的にも面白みに優れたものとなり、高い商品価値が得られる。
【００７０】
また、眼鏡１を軽くて丈夫なレンズシート41によって形成すれば、激しい運動を行っても眼鏡１の質量が小さいので慣性力による装着ストレスが生じにくく、顔面からはずれにくいので、直射日光の下でスポーツなどを行うときに眼101を保護するためのサングラスとしての用途もある。
【実施例９】
【００７１】
図１５及び図１６は、本発明の実施例９を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では、前記レンズ２Ａと脚部３Ａとの間に、前後方向の段差部42を設けており、レンズ２Ａより脚部３Ａが裏面側に位置する。
【００７２】
したがって、装着時にレンズ２Ａの両端側と顔面と間に前記段差部42に対応した隙間が得られる。
【実施例１０】
【００７３】
図１７及び図１８は、本発明の実施例１０を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例ではレンズ面の一部にフレネルレンズ様の段差を有するレンズ２Ｂ，２Ｂを用いる以外は実施例５と共通である（図１７参照）。
【００７４】
このように本実施例では、上記各実施例と同様な作用・効果を奏するが、さらに、請求項８に対応して、左右のフレネルレンズ様の段差面を有するレンズ２Ｂ，２Ｂを備え、これらのレンズを軽量化することによって、眼鏡１を装着したときの装着ストレスが減ずる。
【００７５】
フレネルレンズ様の段差面を有するレンズを形成する場合、レンズの耐久性を増すため、なるべく鋭利なエッジを造らないように段差面の形状を考えねばならない。また段差面を通過する光束がなるべく眼に入射しないように段差面の角度を考慮しなければならない。これらの理由から凸レンズにおいては眼101と反対にあるレンズの外表面に同心円上に段差面51Ａを設け、凹レンズにおいては眼と同側にあるレンズの内表面に段差面51Ｂを設け、これら段差面51Ａ、もしくは51Ｂを、眼101を頂点とする円錐面の一部として形成するのが合理的である（図１７参照）。ただし、これらの原則から外れた段差面51Ａ，51Ｂでもレンズの厚さを減ずることは可能である。本実施例11では２本の同心円状の軌道に沿って段差面51Ａ，51Ｂを設けているが、段差面の面数については特に定めるものではない。尚、通常は51Ａを有する凸レンズ２Ｂか、段差面51Ｂを有する凹レンズ２Ｂのいずれか一種類を用いればよい。
【００７６】
屈折力が強く、広い視野をカバーするレンズは、凸レンズ、凹レンズにかかわらず厚みが増え、重量が増加する。一方、同心円状に多数の段差を持つフレネルレンズはシート状に薄くすることができるが、光学的な性能が良くない。しかし、人間の眼において良好な視力を有するのは視野の中心部のわずかな範囲であり、この部分にのみ良好な光学性能を必要とする小口径の薄いレンズ部２Ｃを配し、視力が劣る視野の周辺部分には段差面を設けて薄くしたレンズを配すれば、視野の中心部分の良好な光学性能と広い視野とを両立させながら、屈折力の強いレンズを必要とする眼鏡１を軽量化できる。
【００７７】
本発明の最も重要な工夫は軽量化した眼鏡１を用いることで装着ストレスを減ずることにある。実施例５では１．５Ｄの凸レンズや凹レンズを用いた場合、通常の眼鏡と比較して、数分の一程度まで重量を減ずることができる。しかし、視力矯正をするためにより強い屈折力を持つレンズを要する人の場合、そのままではレンズが厚く重くなってしまい、装着ストレスを効率的に減ずることができない。そのような屈折力が強いレンズを要する人でも、本実施例１０のようにレンズ２Ｂに何面かの段差を設けることでレンズを薄型にできるので、本発明の眼鏡１を効率的に軽量化し、装着ストレスを少なくした状態で使用することが可能となる。
【００７８】
なお、本発明は、前記実施例に限定されるものではなく、種々の変形実施が可能である。例えば、レンズに設ける脚部の数や配置、レンズを連結する部材の材料などは適宜選定可能である。また、シート12は皮膚面のカーブに沿う柔軟性を有するものを用いることができる。
【実施例１１】
【００７９】
図１９〜図２１は、本発明の実施例１１を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述すると、この例では請求項４の眼鏡に対応し、眼鏡１を前額側面やこめかみ、両眼の外側、頬などの皮膚に付着させた取付部材11Ｕ，11Ｌを用いて顔面に装着させる（図１９）。この実施例の場合、取付部材11Ｕ，11Ｌを付着させる顔面の皮膚部位は頭部側面に位置し、左右それぞれ少なくとも１本、この例では合計四本の脚部３Ｕ，３Ｌと合計四個の取付部材11Ｕ，11Ｌで頭部をはさむ様にし、少ない粘着力で安定した眼鏡１の保持を可能とする。このとき脚部３Ｕ, ３Ｌの機能として、一定の弱い圧力（皮膚に押し付ける力）を取付部材11Ｕ，11Ｌに加え続けることによって皮膚粘着面14の粘着力を補うが、ニッケルチタン合金等の超弾性を有する線材４で脚部３Ｕ，３Ｌを作製することによってこの目的を果たすことできる。すなわち、装着前における左右の取付部材11Ｕ，11Ｌの間隔に比べて、装着状態では左右の取付部材11Ｕ，11Ｌが広がるため、弾性を有する線材４の弾性復元力により、取付部材11Ｕ，11Ｌを皮膚の押し付ける力が得られる。また、線材４の超弾性によって取付部材11Ｕ，11Ｌの皮膚に対する粘着力が補われるため、皮膚粘着面14の粘着力がある程度低下しても安定した眼鏡１の保持ができる。従って、眼鏡１の掛けはずしのたびに取付部材11Ｕ，11Ｌを眼鏡１本体と一体のものとして顔面から取り除いても、眼鏡１を繰り返し装着し続けることが可能である。
【００８０】
取付部材11Ｕ，11Ｌと眼鏡１本体を一体として使用する場合、取付部材11Ｕ, 11Ｌと脚部３Ｕ，３Ｌの着脱手段は、取付部材11Ｕ，11Ｌの皮膚粘着面14を洗浄したり、新たな取付部材11Ｕ，11Ｌと交換するときのみに使用するだけで良い。従って必ずしも磁石などの着脱が容易な手段を使用する必要がなく、請求項７のねじや粘着性両面テープなど、多彩な着脱手段を用いることが可能である。
【００８１】
実施例１１では脚部３Ｕ, ３Ｌの先端に柔軟性を有する筒部材21Ａを取り付け、この中に取付部材11Ｕ，11Ｌに設けた突起15をはめ込むことで脚部３Ｕ，３Ｌと取付部材11Ｕ，11Ｌの着脱手段としている（図２０（Ａ））。この筒部材21Ａにはめ込んだ取付部材11Ｕ，11Ｌは自由に回転させることができ、また筒部材21Ａ自体に柔軟性があるので、取付部材11Ｕ，11Ｌの皮膚粘着14とこれを付着させる皮膚とが概略平行になるように取付部材11Ｕ，11Ｌの角度調節を行うことができる。
【００８２】
すなわち、この例では、脚部３Ｕ，３Ｌの先端にはめ込んだ筒部材21Ａが、一方の着脱手段、前記突起１５が他方の着脱手段となり、あるいは脚部３Ｕ，３Ｌの先端が一方の着脱手段、前記突起１５にはめ込んだ前記筒部材２１Ａが他方の着脱手段となり、それら着脱手段により眼鏡１の取付部材１１Ｕ，１１Ｌを交換可能に構成している。この場合、筒部材２１Ａに、線材状をなす突起１５を挿入して取り付けるため、筒部２１Ａに対し、突起１５を中心として、取付部材１１Ｕ，１１Ｌを回転することにより、その向きを調整することもできる。
［００８３］
近年シリコンゲルやウレタンゲルなど、適度の粘着性と柔軟性、衝撃吸収作用を併せ持つ粘着性ゲルが開発され、市販されている。実施例１１の眼鏡１の場合、取付部材１１Ｕ，１１Ｌと皮膚面の間に脚部３Ｕ，３Ｌの超弾性による力が加わる。従って取付部材１１Ｕ，１１Ｌの本体を粘着性ゲルによって作製すれば、取付部材１１Ｕ，１１Ｌと皮膚との間に生ずる力を粘着性ゲル１６によって分散・緩和することができる（図２０（Ａ））。また、取付部材１１Ｕ，１１Ｌの本体は、粘着性ゲルより強い力学的な強度を有する、粘着性エラストマーで作製してもよい。一般に粘着物が付着面から剥がれるときには、粘着面の一部に応力が集中し、この部分が剥がれることによって徐々に付着面積が減少し、一定の限界を超えると一気に剥がれ落ちてしまう。しかし、柔軟性の強い粘着性ゲル１６で取付部材１１Ｕ，１１Ｌの本体を作製し、しかもこれを脚部３Ｕ，３Ｌの超弾性によって一定の弱い力で常に皮膚面に押しつけ続けると、応力の集中や付着面積が徐々に減少する現象を未然に防止することができる。従って皮膚面１４の粘着力が眼鏡１を何度も掛け外しすることによって減少しても、眼鏡１を安定して顔面に装着し続けることができる。また皮膚粘着面１４を洗浄することによって容易に粘着性を回復させ、繰り返し使用することができる。従って粘着性ゲルで取付部材１１Ｕ，１１Ｌの本体を作製し、脚部３Ｕ，３Ｌの超弾性をも利用して皮膚に付着させることにより、取付部材１１Ｕ，１１Ｌの耐用性が増す。また粘着性ゲル１６に合成樹脂３３Ｂを付着させ、この合成樹脂３３に、線材からなる突起１５を埋め込み、この突起１５を筒状部材２１Ａにはめ込むことによって取付部材１１Ｕ，１１Ｌと脚部３Ｕ，３Ｌの着脱手段とすることができる。
［００８４］
脚部と眼鏡本体との取り付け方法には様々な手段が考えられるが、実施例１１ではレンズ２の外側に一対の孔６，６を近接して穿設し、これら孔６，６に予め変形させた超弾性合金の線材４からなる脚部３Ｕ，３Ｌを挿入するという方法を用いている（図２０（Ｂ））。線材４の屈曲部が二個の孔６，６の位置に来るところまで挿入されると、線材４の弾性により孔６，６の周辺部に線材４が押しつけられ、脚部３Ｕ，３Ｌの位置が自動的に安定する。すなわち、図２１に示すように、線材４を、予めその先端側が開くように略Ｖ字状に屈曲しておく。この取り付け方法はねじや接着剤を要しないので信頼性が高く、また脚部３Ｕ，３Ｌの取り外しが簡単にできるので、脚部３Ｕ，３Ｌの形状を使用者の顔面に合わせて調整することが容易である。
【００８５】
実施例１１の眼鏡１の装着方法について説明すると、まず鼻当61を鼻102に当てることによって、眼鏡１の位置を概略定める。次にこの位置を固定するため、脚部３Ｕの先の取付部材11Ｕを前額側面やこめかみに付着させ、眼鏡１の位置を概略固定する（図２１（Ａ））。この状態では敏感な鼻102の皮膚に鼻当61を介してストレスが加わるため、本発明の目的を十分に達成することができない。そこで脚部３Ｌの先の取付部材 11Ｌを目の外側や頬の部分の皮膚に付着させ、鼻当61が鼻102から浮いた状態で眼鏡１の位置を最終的に固定する（図２１（Ｂ））。このような装着方法を用いることにより、そもそも装着ストレスに高い感受性を有する耳や鼻の皮膚に外力を掛けないようにすることができる。
【００８６】
実施例１１ではレンズの連結部分に鼻当61を有する（図１９）。この鼻当61は眼鏡１を顔面に装着する場合の位置決めのときに用いるので、位置決めが行いやすい様に鼻102の曲面に合わせたプラスチック板で作製している。このプラスチック板の鼻102に対する面にスポンジや軟らかいゲルを貼り付け、鼻102に加わる力を緩和させても良い。眼鏡１が顔面に装着された状態で、鼻当61は鼻102から浮き上がるが、眼鏡１に大きな外力が加わった場合には外力を受け止め、眼鏡１が眼101に接触することを防止するストッパーとしても機能する。
【００８７】
眼鏡１は超弾性を有する脚部３Ｕ，３Ｌによって顔面に装着されているため、眼鏡使用者が頭を動かすと眼鏡１の慣性質量によって眼鏡１本体の振動が生ずる可能性がある。この様な振動は、粘着性ゲル16の力学的な緩衝作用によって吸収し、ある程度抑え込むことができる。さらに眼鏡１の振動を完全に防止するためには鼻当61を鼻102に再び接触させればよい。従って眼鏡１の使用者は、事務作業や読書など頭を殆ど動かさないときは鼻当61を鼻102から浮き上がらせて鼻102に加わる持続的装着ストレスを無くし（図２１Ｂ）、運動などで頭を動かさざるを得ないときは鼻当61を鼻102に接触させて眼鏡１の装着を安定させ（図２１（Ａ））、状況に応じて眼鏡１の装着方法を選択することができる。
【００８８】
このように本実施例では、レンズ２，２と、このレンズ２，２に設けた複数の脚部３Ｕ，３Ｌと、この脚部３Ｕ，３Ｌの先端側に設けた一方の着脱手段たる筒部材21Ａと、この筒部材２１Ａと着脱可能な他方の着脱手段たる突起15を備えた取付部材11Ｕ，11Ｌと、この取付部材11Ｕ，11Ｌに設けられた皮膚粘着面14とを備えるから、適宜位置に、粘着面14により取付部材11を複数取り付け、レンズ２を眼101の前に装着することができる。
【００８９】
また、この例では、眼鏡１の左右に配置した取付部材11Ｕ，11Ｌにより、頭部をはさむ様にして装着するため、線材４の弾性復元力により取付部材11Ｕ，11Ｌに押し当て、少ない粘着力で安定した眼鏡１の保持が可能となる。
【産業上の利用可能性】
【００９０】
人体に直接使用できる刺激性が低い粘着剤や粘着性と衝撃緩衝作用を併せ持つ粘着性ゲル、小型でも十分強力な永久磁石、十分な機械的強度と耐衝撃性を持つレンズ用プラスチック素材、ニッケルチタン合金等の超弾性合金などの材料は既に市販されている。従って本発明の眼鏡１は工業的に量産することが可能であり、産業上の利用可能性を有する。また、取付部材11の粘着力は剥離・再接着を繰り返すことによって低下するが、皮膚粘着面14を洗浄する、両面テープ状に加工した粘着剤を張り替える、あるいは予備の取付部材11と交換することで解決可能である。また、本発明の眼鏡１は使用者の顔面の形状に合わせて調整することが望ましいが、この目的のためには模擬レンズと取付部材11を針金などの変形できる脚部でつないだ型取り専用部品を利用することができる。

The present invention relates to eyeglasses, and more particularly, to eyeglasses that are reduced in weight so as to be able to relieve wearing stress locally applied to the skin in a portion that comes into contact with the eyeglasses when worn.
[Background]
[0002]
When wearing eyeglasses, stress is applied to the vines on the ears and the skin on the nose pads. In particular, wearing stress becomes unbearable due to wearing for a long time or intense exercise. One effective method for reducing the wearing stress of spectacles is to reduce the weight of spectacles (including sunglasses). Various efforts have been made to reduce the weight, but in order to further reduce the weight, it is necessary to drastically change the shape of the glasses and to devise a wearing method.
[0003]
The idea of attaching the spectacles directly to the skin of the face using an adhesive by devising the wearing method in consideration of such problems has already been filed (see, for example, Patent Document 1 and Patent Document 2). However, when the glasses are directly attached to the face using an adhesive, the adhesive surface is soiled with sweat or sebum by repeating fine adjustment of the wearing position and wearing / removing of the glasses, and the adhesive strength rapidly decreases. Therefore, in patent document 2, it restricts to temporary mounting | wearing.
[0004]
Further, an idea has been already filed for an idea of preventing spectacles from slipping off by attaching a magnetic substance to the skin of the nose and attaching a magnet attached to the nose to the nose (for example, Patent Document 3). However, since this spectacle uses a nose pad portion that fixes the spectacles so as to sandwich the nose, mounting stress occurs in the nose portion where the nose pad portion hits during mounting.

DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0005]
An object of the present invention is to provide spectacles that can reduce the size and weight of the spectacles and reduce the stress applied to the skin when the spectacles are applied to the face.
[Means for Solving the Problems]
[0006]
The invention of claim 1 includes a lens, a plurality of legs provided on the lens, one attachment / detachment means provided on the distal end side of the legs, and the other attachment / detachment means detachable from the one attachment / detachment means. The attachment member provided and the skin adhesive surface provided on the attachment member are provided.
[0007]
According to a second aspect of the present invention, the one and the other attachment / detachment means are a permanent magnet and a permanent magnet, or a permanent magnet and a magnetic body, or a magnetic body and a permanent magnet.
[0008]
According to a third aspect of the present invention, the left and right lenses are provided, and the left and right lenses are connected.
[0009]
According to a fourth aspect of the present invention, the connected left and right lenses are supported by the attachment members attached to the skin such as the forehead side surface, the temple, the outer sides of both eyes, and the cheeks, and the wearing stress is applied to the ear and nose skin. Is not added.
[0010]
According to a fifth aspect of the present invention, the one and the other attaching / detaching means are a parallel magnet and a parallel magnet, or a parallel magnet and a magnetic body, or a magnetic body and a parallel magnet, and the parallel magnet is composed of two permanent magnets. The polarities are reversed and arranged in parallel to prevent the magnetic field lines from diffusing.
[0011]
According to a sixth aspect of the present invention, the one and the other attaching / detaching means are provided on the engaging protrusion provided on the tip end side of the leg portion and the protrusion engaging portion provided on the mounting member, or on the tip end side of the leg portion. A protrusion locking portion provided and a locking protrusion provided on the mounting member, wherein the locking protrusion and the protrusion locking portion are detachable.
[0012]

【The invention's effect】
[0014]
According to the configuration of the first aspect, the attachment member is attached to the appropriate position around the outside of the eye by the adhesive surface, and the lens is attached to the front of the eye by the attachment member attaching / detaching means and the leg attaching / detaching means. This spectacle does not have a frame or a vine and is lightweight, and only a plurality of attachment members are in contact with each other, so that the wearing stress is small. Thus, it is possible to reduce the size and weight of the eyeglasses that are integrated as a rigid body, and the force generated between the skin and the glasses is reduced by the reduction in size and weight. Further, when unnecessary, only the lens and the leg can be easily detached by the attaching / detaching means.
[0015]
Furthermore, the mounting member and the spectacle body can be used as a unit. In this case, when the adhesive surface is soiled with sweat or sebum by repeatedly removing and attaching the glasses, and the adhesive force of the mounting member to the skin surface is reduced, a new mounting member is attached by using the mounting member and the leg part attaching / detaching means. Can be replaced with the main body of the glasses.
[0016]
Moreover, according to the structure of Claim 2, by using a magnet for an attachment or detachment means, it can carry out very easily.
[0017]
According to the third aspect of the present invention, the convenience when wearing glasses is improved by connecting the left and right lenses.
[0018]
Then, a pair of left and right thin lenses are attached to two skins around the eyes, such as the forehead and the outside of both eyes, by attaching an attachment member with an adhesive surface and connected by means of attaching / detaching the attachment member and means for attaching / detaching the leg. Wear in front of eyes. The connecting portion of the two thin lenses can be brought into contact with the nose to stabilize the lens position. Furthermore, a buffer material such as sponge, rubber, or gel substance can be attached to the connecting portion, and the nose can be contacted through the buffer material. Usually, the weight of glasses is about 10 to 20 grams. For example, a convex lens or a concave lens having a refractive power of 1.5D is formed into a thin shape using a plastic material having sufficient mechanical strength and impact resistance. In this case, the weight of the glasses including the attachment member can be reduced to about a fraction of the weight. This significant weight reduction reduces the force generated between the skin and the glasses and relieves wearing stress. Furthermore, by attaching a sheet-like attachment member to the skin in contact with the glasses for protection, the mounting stress is reduced. When glasses are not required, only the connected lens and legs can be easily removed by the attaching / detaching means. Further, when the attachment member is attached to the forehead portion, the glasses can be turned over and attached to the forehead, and can be held so as not to obstruct the field of view.
[0019]
According to the fourth aspect of the present invention, the four attachment members are attached to the spectacle body comprising the connected left and right lenses via the left and right legs. When wearing the spectacles on the face, first, the nosepiece attached to the lens connecting portion of the main body is brought into contact with the nose to roughly determine the position of the spectacle main body. Next, one attachment member on each of the left and right sides is attached to the side surface of the forehead or the left and right skins of the temple, and the position of the spectacle body is roughly fixed. In addition, the left and right mounting members are attached to the left and right skins such as the cheeks and other left and right positions, and the nosepiece is lifted from the nose by finely adjusting the angle of the glasses body. Finally fix the position of the glasses body. As described above, in the eyeglasses according to the fourth aspect, the eyeglass body is supported by the four attachment members attached to the skin such as the forehead side surface, the temple, the outer sides of both eyes, and the cheeks, and the ear and nose have high sensitivity to wearing stress. The eyeglass position can be maintained in a state where no continuous force is applied to the skin.
[0020]
At present, spectacles having a vine to be worn on the ear are generally used. Conventionally, spectacles that keep the wearing position by pressing the tip portion of the vine against the temple portion or the temporal region have been used. There are several types of glasses that are recently modified from this design and that do not have vines on the ear. However, since these glasses generally support the weight of the glasses body with a nosepiece, the wearing stress applied to the skin of the nose is not reduced. According to the fourth aspect of the present invention, the surface of the attachment member with respect to the skin is made sticky to increase the adhesion between the attachment member and the skin. Therefore, it is possible to stably hold the position of the glasses by simply attaching a plurality of mounting members to the skin on the side of the forehead, the temple, the outside of both eyes, the cheeks, etc. Sustainable wearing stress is not applied. In this regard, the eyeglasses of claim 4 are completely different from the conventional eyeglasses that do not have a vine to be worn on the ear.
[0021]
According to the fifth aspect of the present invention, the permanent magnet is used for the attachment / detachment means between the spectacle leg and the mounting member, but the two permanent magnets are used by reversing the polarity. Since the magnetic lines of force generated from the magnets arranged in parallel cancel each other at a long distance, it is possible to prevent the magnetic field lines from spreading and reduce the possibility of adverse effects on electronic devices such as pacemakers.
[0022]
Further, according to the configuration of the sixth aspect, by using the locking projection and the locking hole that can be attached and detached to the attaching / detaching means of the spectacle leg portion and the mounting member, The pair of locking projections can be used as the center of rotation to rotate the glasses up and down. Therefore, when the spectacles are no longer needed, the spectacles can be easily held upside down on the forehead by rotating around the locking projection.
[0023]
Further, according to the configuration of the seventh aspect, the screw is used for the attachment / detachment means between the spectacle leg portion and the mounting member. However, by setting the screw in the horizontal direction, the pair of left and right screws are used as the center of rotation. Can rotate in the vertical direction. Therefore, when the spectacles are no longer needed, the spectacles can be easily held on the forehead by rotating them around the screw.
[0024]
According to the eighth aspect of the present invention, a lens is used in which a step is provided on the lens surface to reduce the thickness. A large-diameter convex lens or concave lens that has a strong refractive power and covers a wide field of view increases in thickness and weight. On the other hand, a Fresnel lens having many steps concentrically can be thinned into a sheet, but its optical performance is not good. The lens having a stepped surface according to claim 8 is provided with a small-diameter lens portion at a central portion of a visual field that requires good optical performance, and a lens having several stepped surfaces at a peripheral portion of the visual field. Thus, it is possible to reduce the weight of the lens having strong refractive power while ensuring both good optical performance at the center of the field of view and a wide field of view.

The lens 2 can be mounted in a state of being suspended by the legs 3, and the stability is excellent.
[Example 5]
[0048]
FIGS. 7-10 shows Example 5 of this invention, attaches | subjects the same code | symbol to the same part as each said Example, and abbreviate | omits the detailed description, and spectacles 1 are two thin-shaped. Lenses 2 and 2 are used, and the lens 2 is a lens that corrects visual acuity or a lens of sunglasses that adjusts the light transmittance, and has a shape corresponding to the eye 101 of the wearer as shown in FIG. Have. The left and right lenses 2 and 2 are connected by a connecting member 31. The connecting member 31 is made of a wire such as a wire bent in a substantially U shape and having a predetermined shape retaining property, and is a portion that contacts the nose 102 at the bottom of the U shape. Can be provided with a cushioning material 32 such as sponge, rubber or gel-like substance. The connecting member 31 is connected to the lens 2 by bending both ends or providing enormous portions, and burying both ends of the bent or enlarging connecting member 31 in a synthetic resin 33 or the like attached to the rear surface on the edge side of the lens 2. .
[0049]
The leg portion 3 is provided on the peripheral side of the connected lens 2, and the leg portion 3 includes the wire 4 having a base end connected to the lens 2 and a parallel magnet provided at the tip of the wire 4. 5A and 5B. The parallel magnets 5A and 5B, which are one of the attachment / detachment means, have different magnet polarities on the attracting surface. That is, the parallel magnet is formed by arranging the permanent magnets 5A and 5B side by side, and the parallel magnets 5A and 5B form S pole, N pole or N pole and S pole on one surface, and the parallel magnet 5A on the other surface. , 5B form N pole, S pole or S pole, N pole.
[0050]
And in this Example 5, the leg part 3 is provided with respect to the lens 2 at two places corresponding to the upper part of the left and right eyes 101 of the wearer so that the eyeglasses 1 can be worn while being suspended. is there. The wire 4 is made of a flexible material such as a wire and having a predetermined shape-retaining property, and is attached to a synthetic resin 33 having a bent or enormous tip of the wire 4 attached to the edge side of the lens 2. It is buried and connected to the lens 2.
[0051]
Further, parallel magnets 5A and 5B having different polarities of the magnets on the attracting surface are attached to the tip of the wire rod 4. The wire rod 4 is formed with a folded portion 4B whose tip is bent like a hook, and the parallel magnets 5A and 5B are arranged in the folded portion 4B, and the folded portion 4B and the parallel magnets 5A and 5B are arranged. And the synthetic resin 33A are solidified and integrated, and as shown in FIG. 8A, the adsorption surfaces of the parallel magnets 5A and 5B are exposed so that both surfaces function as adsorption surfaces. To form. The leg part 3 is provided with a shape-retaining property that keeps a distance between the lenses 2 and 2 and the eye 101 in the mounted state.
[0052]
Further, the glasses 1 include two attachment members 11 corresponding to the two legs 3. This attachment member 11 is formed by forming a sheet 12 having a color that is transparent or close to the skin into a substantially oval shape, and on the surface of the sheet 12, parallel magnets 13A and 13B having different polarities of the magnets of the adsorption surface as the other attaching / detaching means. Is attached. These parallel magnets 13A and 13B are embedded in the sheet 12 or attached to the surface. The sheet 12 is formed in a curved surface that matches the curve of the skin surface. A skin adhesive surface 14 is formed on the back surface of the sheet 12 by applying an adhesive or attaching an adhesive double-sided tape. Further, the dimension of the substantially elliptical sheet 12 is about 10 mm and 20 mm in the minor axis and the major axis, respectively. The parallel magnets 5A and 5B and the parallel magnets 13A and 13B are arranged in parallel in the vertical direction.
[0053]
Next, a method of using the glasses 1 will be described. The attachment member 11 is bonded to two skins of the forehead 104 on the left and right eyebrows 103 by the adhesive surface 14. Then, the parallel magnets 5A and 5B of the corresponding leg 3 are attracted to the parallel magnets 13A and 13B of the mounting member 11, so that the lenses 2 and 2 connected in front of the eye 101 are arranged and the glasses 1 are worn. . At this time, due to the elasticity of the leg 3, the connecting member 31 that connects the left and right lenses 2 and 2 is in contact with the nose 102 directly or via the cushioning material 32, so that the positions of the lenses 2 and 2 are stably maintained. .
[0054]
When the glasses 1 are not used, the parallel magnets 5A and 5B and the parallel magnets 13A and 13B are pulled apart, and the connecting lenses 2 and 2 are removed leaving the attachment member 11. Even in this state, the small mounting member 11 is hardly conspicuous, and even if it is as it is, there is little uncomfortable feeling, and an operation that does not require the glasses 1 can be performed. When the glasses 1 are needed for reading or the like, the connecting lenses 2 and 2 can be attached again.
[0055]
Further, as shown in FIG. 10 (B), the removed glasses 1 are turned over, and the parallel magnets 5A and 5B of the leg 3 are attracted to the parallel magnets 13B and 13A of the mounting member 11 in that state. It is also possible to hold the glasses 1 on and keep wearing the glasses 1 in a form that does not obstruct the field of view.
[0056]
Thus, in this embodiment, in correspondence with claim 3, the lens 2, the leg 3 provided on the lens 2, and the parallel magnet 5A as one of the attaching / detaching means provided on the distal end side of the leg 3 are provided. 5B, a mounting member 11 provided with parallel magnets 13A and 13B as other attaching / detaching means that can be attached to and detached from the parallel magnets 5A and 5B, and a skin adhesive surface 14 provided on the mounting member 11; 2 and 2 and these left and right lenses 2 are connected. For example, two attachment members 11 are attached to the front forehead 104 on the eyebrow 103 by an adhesive surface 14 at an appropriate position. The lenses 2 and 2 are mounted in front of the eye 101 by 13A and 13B and the parallel magnets 5A and 5B of the leg 3. The eyeglasses 1 have no frame or vine hooks and are lightweight. Further, since the two attachment members 11 and the connecting member 31 are in contact with the skin directly or only through a cushioning material 32 such as a sponge, rubber, or gel material, the mounting stress is small. By reducing the weight of the glasses 1, the force generated between the skin and the glasses 1 is reduced. When the glasses 1 are unnecessary, the parallel magnets 5A and 5B and the parallel magnets 13A and 13B can be pulled apart, and only the connecting lenses 2 and 2 can be easily removed. Alternatively, the eyeglasses 1 can be turned over and mounted on the forehead that does not obstruct the field of view.
[0057]
The number of leg portions 3 attached to the connected lenses 2 and 2 is not particularly limited. However, considering the ease of wearing, it is reasonable to use two legs in total. Further, although the attachment site of the attachment member 11 is not particularly limited, as shown in the present embodiment, two places on the forehead 104 above the eye 101, two places on the outer part of the left and right eyes 101, Alternatively, it is reasonable to select two temples.
[0058]
In addition, when pasting glasses directly on the face using an adhesive or adhesive double-sided tape as in the past, the adhesive surface becomes soiled with sweat or sebum by repeating fine adjustment of the wearing position and wearing of the glasses, Adhesive strength decreases rapidly. In contrast, in the present invention, only the attachment member 11 is attached directly to the skin, not the main body of the glasses / sunglasses, and the eyeglasses 1 are repeatedly attached and detached repeatedly by attracting and peeling with a permanent magnet or the like. However, since the attachment / detachment means does not reduce the adsorption force, the adhesive force does not decrease. Further, if several sets of spare mounting members 11 are prepared, they can be quickly replaced when the adhesive force is reduced.
[0059]
In this embodiment, since the one and the other attaching / detaching means are the parallel magnets 5A, 5B and the parallel magnets 13A, 13B, a good fixed state can be obtained and the hooking and unloading can be performed very easily. In addition, since the magnetic lines of force generated from the magnets arranged in parallel cancel each other at a long distance, it is possible to prevent the magnetic field lines from spreading and reduce the possibility of adverse effects on electronic devices such as pacemakers. One attachment / detachment means is the parallel magnets 5A, 5B, and the other attachment / detachment means is a magnetic body that is adsorbed by the parallel magnets 5A, 5B, and this magnetic body is provided on the attachment member 11, or one attachment / detachment means is the above-described attachment / detachment means. The parallel magnets 13A and 13B may be magnetic bodies that are attracted, the magnetic body may be provided on the leg 3, and the other attaching / detaching means may be the parallel magnets 13A and 13B.
[0060]
In the present embodiment, the parallel magnets 5A and 5B and the parallel magnets 13A and 13B that prevent the magnetic field lines from diffusing to a long distance are used. However, if the magnetic field lines are not considered to be diffused, a single permanent magnet can be used. A permanent magnet, or a single permanent magnet and a magnetic body, or a magnetic body and a single permanent magnet may be attached to the leg 5 and the attachment member 11, respectively, as attachment / detachment means.
[0061]
The glasses 1 of the present invention can be reduced in weight. For example, when a convex lens or concave lens having a refractive power of 1.5D is molded thinly using a plastic material having sufficient mechanical strength and impact resistance, the weight of the glasses including the mounting member is about several grams. Is possible. This weight reduction reduces the force generated between the skin and the glasses 1. Further, by attaching a sheet-like attachment member 11 to a portion in contact with the glasses 1 to protect the skin, the mounting stress can be further reduced.
[0062]
The spectacles 1 of the present invention shown in Example 5 can be used as spectacles for a person who is forced to wear for a long time while feeling uncomfortable with the stress of wearing the spectacles. In addition, when an appropriate attachment / detachment means for attaching to the leg portion 3 and the attachment member 11 is used, the leg portion 3 can be attached to the attachment member 11 even if the eyeglasses 1 are turned over. In this case, the visual field is not obstructed. Since the spectacles 1 can be attached to the forehead 104, it can be used as spectacles for people who need frequent wearing of the spectacles.

Therefore, by setting the locking projections 35 in the left and right lateral directions, the glasses 1 can be rotated in the vertical direction with the pair of left and right locking projections 35 as the rotation center. Therefore, when the spectacles 1 are no longer needed, the spectacles 1 can be easily held upside down on the forehead 104 by rotating around the locking hole 36.
[Example 7]
[0065]
FIG. 13 shows a seventh embodiment of the present invention. The same reference numerals are given to the same parts as those of the above-mentioned embodiments, and detailed description thereof is omitted. A modification is shown, and one attaching / detaching means is a through hole 37 as a screw receiving part or a screw hole 38 as a screw receiving part, and the other attaching / detaching means is a screw hole 38 or a through hole 37, and is inserted into the through hole 37. By screwing the screw 39 into the screw hole 38, the leg portion 3 provided with the through hole 37 and the screw hole 38 and the mounting member 11 are configured to be detachable. The through hole 37 and the screw hole 38 are formed in the attaching / detaching means main body 34 </ b> A, and the attaching / detaching means main body 34 </ b> A is provided in the leg portion 3 and the attachment member 11. The attaching / detaching means main body 34A has a substantially cylindrical shape.
[0066]
Thus, in this embodiment, corresponding to claim 7, one and the other attachment / detachment means are the through-hole 37 and the screw hole 38 which are screw receiving portions, so the screw 39 is used and the screw 39 is attached in the mounted state. By configuring the direction to be set in the horizontal direction, the glasses 1 can be rotated in the vertical direction with the pair of left and right screws 39 serving as the rotation center. Therefore, when the spectacles 1 are no longer needed, the spectacles 1 can be easily held on the front forehead 104 by being rotated around the screw 39.
[Example 8]
[0067]
FIG. 14 shows an eighth embodiment of the present invention. The same reference numerals are given to the same parts as those of the above-mentioned embodiments, and detailed description thereof is omitted. The spectacles 1 of this example is used as sunglasses. The left and right lenses 2A, 2A, their connecting members 31A, and legs 3A, 3A are formed of a lens sheet 41 made of synthetic resin or the like (see FIG. 14). The lens sheet 41 can be colored or provided with a half mirror function, a function as a polarizing filter, an antireflection function, or the like. A buffer material 32A is provided on the back surface of the connecting member 31A, and the parallel magnets 5A and 5B are attached to the back surface of the leg 3A. Separate parallel magnets 13A and 13B are attached to the attachment member 11A having a substantially circular shape, and are attached to two skins on the outside of the eye 101 with an adhesive surface. The attachment member 11A is configured to be substantially hidden by the glasses 1 in the mounted state. The buffer material 32A is in contact with the nose and stabilizes the position of the glasses 1.
[0068]
In the eighth embodiment, an example is shown in which the distances between the parallel magnets 5A and 5B and the parallel magnets 13A and 13B are increased. Thus, if the distance between the magnets arranged in parallel is increased as necessary, the diffusion range of the lines of magnetic force is also increased, so that the glasses 1 can be easily attached.
[0069]
In the present embodiment, the glasses 1 are sunglasses in which the lenses 2A and 2A are colored, and have the same functions and effects as those in the above embodiments. In this example, the back surface of the colored glasses 1 is used. Since the mounting member 11A is substantially hidden from the front, the mounting structure is not visually recognized from the front side, and the appearance is as if only the glasses 1 were mounted alone, and the design is also interesting and high commercial value is obtained. .
[0070]
Further, if the spectacles 1 are formed by the light and durable lens sheet 41, the mass of the spectacles 1 is small even when exercising vigorously, so that stress due to inertia is less likely to occur and it is difficult to be detached from the face. It can also be used as sunglasses to protect the eye 101 when performing sports or the like.

The same reference numerals are assigned to the same parts as those in the above-described embodiments, and detailed description thereof is omitted. In this example, the lens 2A and A step part 42 in the front-rear direction is provided between the leg part 3A and the leg part 3A is located on the back side of the lens 2A.
[0072]
Accordingly, a gap corresponding to the stepped portion 42 is obtained between the both end sides of the lens 2A and the face when worn.
[Example 10]
[0073]
FIGS. 17 and 18 show Embodiment 10 of the present invention. The same reference numerals are given to the same portions as those in the above-described embodiments, and detailed description thereof will be omitted. In this example, a part of the lens surface is shown. The second embodiment is the same as the fifth embodiment except that lenses 2B and 2B having a Fresnel lens-like step are used (see FIG. 17).
[0074]
As described above, the present embodiment provides the same operations and effects as the above embodiments, but further includes lenses 2B and 2B having left and right Fresnel lens-like stepped surfaces, corresponding to claim 8, By reducing the weight of the lens, the wearing stress when wearing the glasses 1 is reduced.
[0075]
When forming a lens having a stepped surface like a Fresnel lens, in order to increase the durability of the lens, the shape of the stepped surface must be considered so as not to create as sharp an edge as possible. Further, the angle of the step surface must be considered so that the light beam passing through the step surface is not incident on the eye as much as possible. For these reasons, a convex lens has a step surface 51A on a concentric circle on the outer surface of the lens opposite to the eye 101, and a concave lens has a step surface 51B on the inner surface of the lens on the same side as the eye. It is reasonable to form 51A or 51B as a part of a conical surface having the eye 101 as a vertex (see FIG. 17). However, it is possible to reduce the lens thickness even on the step surfaces 51A and 51B that deviate from these principles. In the eleventh embodiment, the step surfaces 51A and 51B are provided along two concentric circular tracks, but the number of step surfaces is not particularly defined. In general, any one of a convex lens 2B having 51A and a concave lens 2B having a step surface 51B may be used.
[0076]
A lens that has a strong refractive power and covers a wide field of view increases in thickness and weight regardless of whether it is a convex lens or a concave lens. On the other hand, a Fresnel lens having many steps concentrically can be thinned into a sheet, but its optical performance is not good. However, the human eye has a good visual acuity in a small range at the center of the visual field, and a small-diameter thin lens portion 2C that requires a good optical performance is disposed only in this portion, resulting in poor visual acuity. By providing a thin lens with a stepped surface at the periphery of the field of view, the eyeglasses 1 that require a lens with a strong refractive power can be reduced while achieving both good optical performance at the center of the field of view and a wide field of view. Can be
[0077]
The most important contrivance of the present invention is to reduce the wearing stress by using the glasses 1 reduced in weight. In Example 5, when a 1.5D convex lens or concave lens is used, the weight can be reduced to a fraction of that of normal glasses. However, in the case of a person who requires a lens having a stronger refractive power for correcting vision, the lens becomes thick and heavy as it is, and the mounting stress cannot be reduced efficiently. Even a person requiring such a lens having a strong refractive power can reduce the thickness of the lens 2B by providing several steps on the lens 2B as in the tenth embodiment. , It can be used in a state where the mounting stress is reduced.
[0078]
In addition, this invention is not limited to the said Example, A various deformation | transformation implementation is possible. For example, the number and arrangement of the leg portions provided on the lens, the material of the member connecting the lenses, and the like can be selected as appropriate. Further, the sheet 12 may be a sheet having flexibility along the curve of the skin surface.
Example 11
[0079]
19 to 21 show an eleventh embodiment of the present invention. The same reference numerals are given to the same parts as those of the above-mentioned embodiments, and detailed description thereof will be omitted. , The eyeglasses 1 are attached to the face using attachment members 11U and 11L attached to the skin such as the forehead side, the temple, the outside of both eyes, and the cheeks (FIG. 19). In the case of this embodiment, the skin part of the face to which the attachment members 11U and 11L are attached is located on the side of the head, at least one each on the left and right, in this example, a total of four legs 3U and 3L and a total of four attachments. The heads are sandwiched between the members 11U and 11L, and the glasses 1 can be stably held with a small adhesive force. At this time, as a function of the legs 3U, 3L, the adhesive force of the skin adhesive surface 14 is supplemented by continuously applying a certain weak pressure (force to press against the skin) to the attachment members 11U, 11L. This object can be achieved by producing the leg portions 3U, 3L with the wire 4 having the following. That is, since the left and right mounting members 11U and 11L spread in the mounted state as compared with the interval between the left and right mounting members 11U and 11L before mounting, the mounting members 11U and 11L are attached to the skin by the elastic restoring force of the elastic wire 4. The pressing force can be obtained. Further, since the adhesive force of the attachment members 11U and 11L to the skin is supplemented by the superelasticity of the wire rod 4, the glasses 1 can be stably held even if the adhesive force of the skin adhesive surface 14 is reduced to some extent. Therefore, even if the attachment members 11U and 11L are removed from the face as an integral part of the main body of the spectacles 1 each time the spectacles 1 are detached, the spectacles 1 can be repeatedly worn.
[0080]
When the mounting members 11U and 11L and the spectacle 1 main body are used as a unit, the attaching and detaching means of the mounting members 11U and 11L and the legs 3U and 3L cleans the skin adhesive surface 14 of the mounting members 11U and 11L or newly attaches them. It only needs to be used when replacing the members 11U and 11L. Therefore, it is not always necessary to use a means such as a magnet that can be easily attached and detached, and various attaching and detaching means such as a screw and an adhesive double-sided tape according to claim 7 can be used.
[0081]
In the eleventh embodiment, a flexible cylindrical member 21A is attached to the distal ends of the leg portions 3U, 3L, and the projections 15 provided on the attachment members 11U, 11L are fitted therein to thereby fit the leg portions 3U, 3L and the attachment members 11U, 11L. (FIG. 20A). The attachment members 11U and 11L fitted in the cylinder member 21A can be freely rotated, and the cylinder member 21A itself has flexibility, so that the skin adhesive 14 of the attachment members 11U and 11L and the skin to which it is attached are attached. The angle of the attachment members 11U and 11L can be adjusted so as to be approximately parallel.
[0082]
That is, in this example, the cylindrical member 21A fitted to the tips of the legs 3U, 3L is one attaching / detaching means, and the projection 15 is the other attaching / detaching means, or the tips of the legs 3U, 3L are one attaching / detaching means, The cylindrical member 21A fitted into the protrusion 15 serves as the other attachment / detachment means, and the attachment members 11U and 11L of the glasses 1 are configured to be exchangeable by the attachment / detachment means. In this case, in order to insert and attach the wire-like projection 15 to the cylindrical member 21A, the orientation of the cylindrical member 21A is adjusted by rotating the attachment members 11U and 11L around the projection 15. You can also.
[0083]
In recent years, adhesive gels such as silicon gel and urethane gel, which have moderate adhesiveness, flexibility, and shock absorbing action, have been developed and marketed. In the case of the glasses 1 of Example 11, force due to superelasticity of the legs 3U, 3L is applied between the attachment members 11U, 11L and the skin surface. Therefore, if the main body of the attachment members 11U and 11L is made of an adhesive gel, the force generated between the attachment members 11U and 11L and the skin can be dispersed and alleviated by the adhesive gel 16 (FIG. 20A). . Moreover, you may produce the main body of the attachment members 11U and 11L with the adhesive elastomer which has stronger mechanical strength than an adhesive gel. In general, when the adhesive is peeled off from the adhesion surface, stress is concentrated on a part of the adhesion surface, and the adhesion area is gradually reduced by peeling off this part, and when it exceeds a certain limit, it peels off at once. However, when the main body of the attachment members 11U and 11L is made of the adhesive gel 16 having a high flexibility, and it is constantly pressed against the skin surface with a certain weak force by the superelasticity of the legs 3U and 3L, the stress concentration In addition, the phenomenon in which the adhesion area gradually decreases can be prevented. Therefore, even if the adhesive force of the skin surface 14 is reduced by putting the glasses 1 on and off many times, the glasses 1 can be stably worn on the face. Further, the adhesiveness can be easily recovered by washing the skin adhesive surface 14 and can be used repeatedly. Therefore, the durability of the mounting members 11U and 11L is increased by producing the main body of the mounting members 11U and 11L with an adhesive gel and attaching them to the skin using the superelasticity of the legs 3U and 3L. Further, a synthetic resin 33B is attached to the adhesive gel 16, and a protrusion 15 made of a wire is embedded in the synthetic resin 33, and the protrusion 15 is fitted into the cylindrical member 21A, thereby attaching the mounting members 11U and 11L and the legs 3U and 3L. The attachment / detachment means can be used.
[0084]
Various means are conceivable for attaching the leg portion and the spectacle body. In Example 11, a pair of holes 6 and 6 are formed close to the outside of the lens 2, and the holes 6 and 6 are deformed in advance. A method of inserting the leg portions 3U and 3L made of the superelastic alloy wire 4 is used (FIG. 20B). When the bent portion of the wire rod 4 is inserted to the position of the two holes 6 and 6, the wire rod 4 is pressed against the periphery of the holes 6 and 6 by the elasticity of the wire rod 4, and the positions of the legs 3U and 3L Is automatically stabilized. That is, as shown in FIG. 21, the wire 4 is bent in a substantially V shape in advance so that the tip end side is opened. Since this attachment method does not require screws or adhesives, it is highly reliable, and the legs 3U and 3L can be easily removed. Therefore, the shape of the legs 3U and 3L can be adjusted to the user's face. Easy.
[0085]
The wearing method of the glasses 1 according to the eleventh embodiment will be described. First, the position of the glasses 1 is roughly determined by placing the nosepiece 61 against the nose 102. Next, in order to fix this position, the attachment member 11U at the end of the leg 3U is attached to the forehead side surface or the temple, and the position of the glasses 1 is roughly fixed (FIG. 21A). In this state, stress is applied to the skin of the sensitive nose 102 via the nose pads 61, so that the object of the present invention cannot be sufficiently achieved. Therefore, the attachment member 11L at the end of the leg 3L is attached to the skin of the outside of the eye or the cheek, and the position of the glasses 1 is finally fixed in a state where the nose 61 is lifted from the nose 102 (FIG. 21B )). By using such a mounting method, it is possible to prevent external force from being applied to the ear and nose skin that is highly sensitive to mounting stress in the first place.
[0086]
In Example 11, a nosepiece 61 is provided at the connecting portion of the lens (FIG. 19). Since the nose 61 is used for positioning when the spectacles 1 are attached to the face, the nose 61 is made of a plastic plate that matches the curved surface of the nose 102 so that positioning can be easily performed. A sponge or soft gel may be attached to the surface of the plastic plate with respect to the nose 102 to relieve the force applied to the nose 102. The nose 61 is lifted from the nose 102 with the glasses 1 mounted on the face. However, when a large external force is applied to the glasses 1, the nose 61 receives the external force and prevents the glasses 1 from coming into contact with the eyes 101. Also works.
[0087]
Since the spectacles 1 are attached to the face by the legs 3U and 3L having super elasticity, if the spectacles user moves his / her head, the glasses 1 may vibrate due to the inertial mass of the spectacles 1. Such vibration is absorbed by the mechanical buffering action of the adhesive gel 16 and can be suppressed to some extent. Further, in order to completely prevent the glasses 1 from vibrating, the nosepiece 61 may be brought into contact with the nose 102 again. Therefore, the user of the glasses 1 lifts the nose 61 from the nose 102 when office work or reading hardly moves, thereby eliminating the persistent wearing stress applied to the nose 102 (FIG. 21B), and exercising. When it must be moved, the nose 61 is brought into contact with the nose 102 to stabilize the wearing of the glasses 1 (FIG. 21A), and the wearing method of the glasses 1 can be selected according to the situation.
[0088]
As described above, in this embodiment, the lenses 2 and 2, the plurality of legs 3 U and 3 L provided on the lenses 2 and 2, and the cylindrical member that is one of the attaching / detaching means provided on the distal end side of the legs 3 U and 3 L. 21A, the attachment member 11U, 11L provided with the projection 15 as the other attachment / detachment means detachable from the cylindrical member 21A, and the skin adhesive surface 14 provided on the attachment member 11U, 11L. A plurality of attachment members 11 can be attached by the adhesive surface 14 and the lens 2 can be attached in front of the eye 101.
[0089]
Further, in this example, the mounting members 11U and 11L arranged on the left and right sides of the glasses 1 are mounted so as to sandwich the head, so that they are pressed against the mounting members 11U and 11L by the elastic restoring force of the wire 4 and have a small adhesive force. Thus, the glasses 1 can be held stably.
[Industrial applicability]
[0090]
Low-irritant pressure-sensitive adhesive that can be used directly on the human body, adhesive gel that has both adhesiveness and shock-absorbing action, small but sufficiently strong permanent magnet, plastic material for lenses with sufficient mechanical strength and impact resistance, nickel titanium Materials such as superelastic alloys such as alloys are already commercially available. Therefore, the glasses 1 of the present invention can be industrially mass-produced and have industrial applicability. In addition, the adhesive strength of the mounting member 11 decreases with repeated peeling and re-adhesion, but the skin adhesive surface 14 is washed, the adhesive processed into a double-sided tape is replaced, or the spare mounting member 11 is replaced. This can be solved. The glasses 1 of the present invention are preferably adjusted in accordance with the shape of the user's face. For this purpose, the model lens and the mounting member 11 are connected exclusively by a deformable leg portion such as a wire. Parts can be used.
