Description
本発明は、眼鏡フレームのテンプルの改良、詳しくは、板バネ材の張り出しを抑えつつ眼鏡を装着した際の頭部に対するフィット感を一層向上させることができ、また構造的にも丈夫で曲げ変形や捻り変形が起き難く、しかも、製造時において難度の高い加工も不要な眼鏡フレームの弾性テンプルに関するものである。 The present invention improves the temple of the spectacle frame, more specifically, can further improve the fit to the head when wearing spectacles while suppressing the overhang of the leaf spring material, and is also structurally strong and bending deformed The present invention relates to an elastic temple for an eyeglass frame that is difficult to cause twisting deformation and that does not require processing that is difficult at the time of manufacture.
周知のとおり、フィット感に優れた眼鏡フレームとして、左右のテンプルを拡開した際に内側に向かって付勢力が働くバネ蝶番式の眼鏡フレームが知られているが、一般的にバネ蝶番は小型のコイルバネや板バネを使用しているため、バネ蝶番から遠い耳掛け部側の付勢力が小さくなって良好なフィット感が得られ難い。 As is well known, a spring hinge type eyeglass frame is known as an eyeglass frame that has an excellent fit, and that exerts an urging force toward the inside when the left and right temples are expanded. Since the coil spring and leaf spring are used, the urging force on the side of the ear hook part far from the spring hinge is reduced, and it is difficult to obtain a good fit.
そこで、従来においては、メタル枠に長尺の板バネ材を固定してテンプルの基端部を構成することにより、テンプルを過拡開(ヒンジの可動範囲を超えて拡開すること)したときに、メタル枠と一緒に板バネ材を弾性変形させて内向きの付勢力が得られるようにした眼鏡フレームも公知となっている(特許文献１〜３参照)。 Therefore, in the past, when the temple plate was over-expanded (expanded beyond the movable range of the hinge) by forming a base end portion of the temple by fixing a long leaf spring material to the metal frame In addition, a spectacle frame in which a leaf spring material is elastically deformed together with a metal frame so as to obtain an inward biasing force is also known (see Patent Documents 1 to 3).
しかし、上記従来の眼鏡フレームは、湾曲させた板バネ材の両端をテンプル側面に単純に固定するだけの構造であったため、顔面に物がぶつかった際に、テンプル内側に大きく張り出した板バネ材がこめかみに当たって怪我をしたり、またテンプル外側に大きく張り出した板バネ材に物が接触して眼鏡が外れたりする問題が生じ易かった。 However, the conventional spectacle frame has a structure in which both ends of a curved leaf spring material are simply fixed to the temple side surface. Therefore, when an object hits the face, the leaf spring material that protrudes greatly inside the temple. However, it was easy to get injured by hitting the temple, and the glasses would come off due to the object coming into contact with the leaf spring material that protruded greatly outside the temple.
一方、従来においては、テンプルの基端部を、長さ方向および縦幅方向に並べた弾性線材によって構成した眼鏡フレームも公知となっているが(特許文献４参照)、この眼鏡フレームについては、テンプル自体が脆弱な弾性線材から構成されていたため、曲げ方向や捻り方向の負荷ですぐにテンプルが変形してしまう等、強度面の欠点があった。 On the other hand, in the related art, a spectacle frame constituted by elastic wire rods in which the base end portion of the temple is arranged in the length direction and the vertical width direction is also known (see Patent Document 4). Since the temple itself was made of a fragile elastic wire, there was a drawback in strength, such as the temple being deformed immediately by a load in the bending direction or twisting direction.
また、上記文献４に係る眼鏡フレームについては、製造を行うに弾性線材(βチタン線材)の端部と玉状の連結部材とを溶接する必要があったが、接触面積が非常に小さい点接触の状態で両者を溶着する作業には、難度の高いレーザ加工を必要としたため、新規の設備投資や専門技術者の確保を前提としなければならなかった。 In addition, for the spectacle frame according to the above-mentioned document 4, it is necessary to weld the end of the elastic wire (β titanium wire) and the ball-shaped connecting member for manufacturing, but the contact area has a very small contact area. In order to weld the two in this state, laser processing with a high degree of difficulty was required, so it had to be premised on investment in new facilities and securing specialist engineers.
本発明は、従来技術に上記問題があったことに鑑みて為されたものであり、その目的とするところは、板バネ材の張り出しを抑えつつ優れたフィット感を得ることができ、また構造的にも丈夫で曲げ方向や捻り方向の負荷にも耐えることができ、しかも、製造面でも困難が伴わない眼鏡フレームの弾性テンプルを提供することにある。 The present invention was made in view of the above-described problems in the prior art, and the object of the present invention is to obtain an excellent fit while suppressing the overhang of the leaf spring material. An object of the present invention is to provide an elastic temple for a spectacle frame that is durable and can withstand loads in the bending direction and twisting direction, and that is not difficult in terms of manufacturing.
本発明者が上記技術的課題を解決するために採用した手段を、添付図面を参照して説明すれば、次のとおりである。 Means employed by the present inventor for solving the above technical problem will be described with reference to the accompanying drawings.
即ち、本発明は、可動端側に耳掛け部Ｍを有し、かつ、基端側がフロント枠Ｆに連結される眼鏡フレームの弾性テンプル１において、
少なくとも前記基端側から中央までの部位を、側面に長手方向に並設された複数の窓部11b・11bを有する薄板状のメタル枠11から構成すると共に、このメタル枠11に対し、前記窓部11b・11bに挿入可能な複数の湾曲部12a・12aを有する板バネ材12の両端を、湾曲部12a・12a間の谷部Ｂをメタル枠11内側に配置した状態で、かつ、各湾曲部12a・12aの頂部Ｔをメタル枠11外側に配置した状態で固定して構成した点に特徴がある。
That is, in the elastic temple 1 of the spectacle frame which has the ear hooking portion M on the movable end side and the base end side is connected to the front frame F,
At least a portion from the base end side to the center is composed of a thin plate-like metal frame 11 having a plurality of window portions 11b and 11b arranged side by side in the longitudinal direction on the side surface. With both ends of the leaf spring material 12 having a plurality of curved portions 12a and 12a that can be inserted into the portions 11b and 11b, with the valley portions B between the curved portions 12a and 12a being arranged inside the metal frame 11, and each curved shape A feature is that the top portions T of the portions 12a and 12a are fixed in a state of being arranged outside the metal frame 11.
なお、上記弾性テンプル１の板バネ材12に関しては、側面に孔部12b・12b…を設けることによって弾性反発力を調節することもできる。また、上記メタル枠11及び板バネ材12の両方には、充分な強度および付勢力を得るためにβチタン材料を使用するのが好ましい。 In addition, regarding the leaf spring material 12 of the elastic temple 1, the elastic repulsive force can be adjusted by providing holes 12b, 12b. Further, it is preferable to use a β-titanium material for both the metal frame 11 and the leaf spring material 12 in order to obtain sufficient strength and urging force.
また本発明では、上記板バネ材12の固着部を保護するために、耳掛け部Ｍの表面部を構成する合成樹脂製またはエラストマー製の鞘状モダン部材13を、耳掛け部Ｍの芯部を構成するメタル枠11の先端部11cに、板バネ材12の端部を覆うように取着することができる。 Further, in the present invention, in order to protect the fixing portion of the leaf spring material 12, the sheath-like modern member 13 made of synthetic resin or elastomer constituting the surface portion of the ear hook portion M is used as the core portion of the ear hook portion M. Can be attached so as to cover the end portion of the leaf spring material 12.
また更に、本発明においては、曲げ方向や捻り方向の負荷に対する強度を確保するために、メタル枠11の本体部と板バネ材12の形状を、両方共にテンプル基部側からテンプル可動端側にかけて幅が狭くなる近似のテーパ形状とするのが好ましい。 Furthermore, in the present invention, in order to ensure the strength against the load in the bending direction and the twisting direction, both the shape of the main body portion of the metal frame 11 and the leaf spring material 12 have a width from the temple base side to the temple movable end side. It is preferable that the taper has an approximate taper shape that narrows.
他方また、本発明では、上記板バネ材12の各湾曲部12a・12aの側面に、窓部12c・12cを設ける一方、この板バネ材12よりもサイズが一回り小さく、かつ、湾曲部14aが形成された補助板バネ材14の両端を、前記板バネ材12の窓部12c・12cに湾曲部14aを挿入された状態でメタル枠11に固定して付勢力を高めることもできる。 On the other hand, in the present invention, the window portions 12c and 12c are provided on the side surfaces of the curved portions 12a and 12a of the leaf spring material 12, while the size is slightly smaller than the leaf spring material 12, and the curved portion 14a. The urging force can also be increased by fixing both ends of the auxiliary leaf spring material 14 formed with the metal frame 11 with the curved portion 14a inserted into the window portions 12c and 12c of the leaf spring material 12.
一方、本発明においては、上記眼鏡フレームのテンプル構成を採用する代わりに、少なくとも前記基端側から中央までの部位を、薄板状のメタル枠11から構成すると共に、このメタル枠11に対し、長手方向に複数の湾曲部12a・12aを有し、かつ、各湾曲部12a・12aに前記メタル枠11を挿通可能な窓部12c・12cが設けられた板バネ材12の両端を、隣り合う湾曲部12a・12a間の谷部Ｂをメタル枠11内側に配置した状態で、かつ、各湾曲部12a・12aの頂部Ｔをメタル枠11外側に配置した状態で固定する構成を採用することもできる。 On the other hand, in the present invention, instead of adopting the temple structure of the above spectacle frame, at least a portion from the base end side to the center is formed of a thin plate-like metal frame 11, and the metal frame 11 is elongated. Adjacent bends at both ends of the leaf spring material 12 having a plurality of curved portions 12a and 12a in the direction and provided with windows 12c and 12c through which the metal frame 11 can be inserted into the curved portions 12a and 12a. It is also possible to adopt a configuration in which the valley portion B between the portions 12a and 12a is fixed in a state where the valley portion B is disposed inside the metal frame 11 and the top portion T of each curved portion 12a and 12a is disposed outside the metal frame 11. .
本発明では、複数の窓部が長さ方向に並設された薄板状のメタル枠に対して、複数の湾曲部が形成された板バネ材の両端を、窓部に湾曲部を挿入した状態で固定して弾性テンプルを構成したことにより、テンプル内外の一方に対する張り出しを抑制することができるため、顔面に物がぶつかった際に弾性部材で怪我をしたり、弾性部材に物が接触して眼鏡が落下したりするような心配を軽減できる。 In the present invention, with respect to a thin plate-like metal frame in which a plurality of window portions are arranged in the length direction, both ends of a leaf spring material in which a plurality of curved portions are formed are inserted into the window portions. By fixing the elastic temple with the elastic temple, it is possible to suppress overhanging of the inside and outside of the temple, so that when an object hits the face, the elastic member may be injured or the elastic member You can reduce the worry of falling glasses.
しかも、本発明では、テンプルの基端側から中央までの長さを有する板バネ材を弾性部材として使用することによって、板バネ材の端部と耳掛け部との距離を縮めることができるため、テンプルを過拡開した際に適度な付勢力を発揮させることができ、これによって良好なフィット感を実現できる。 Moreover, in the present invention, the leaf spring material having a length from the base end side to the center of the temple is used as the elastic member, so that the distance between the end portion of the leaf spring material and the ear hooking portion can be reduced. When the temple is over-expanded, an appropriate urging force can be exerted, thereby realizing a good fit.
しかも、本発明では、テンプルの基端側を薄板状のメタル枠から構成しているため、弾性線材のように強度が低下する心配もなく、曲げ方向や捻り方向の負荷によってテンプルが簡単に変形してしまうこともない。また、製造面に関しても、メタル枠と板バネ材を面接触させた状態で固着すればよいため、一般的なロウ付けや溶接法で対応できる。 In addition, in the present invention, since the base end side of the temple is formed of a thin plate-like metal frame, there is no risk of the strength being lowered like an elastic wire, and the temple is easily deformed by a load in the bending direction or the twisting direction. There is no end to it. Further, regarding the manufacturing surface, it is only necessary to fix the metal frame and the leaf spring material in surface contact with each other, so that it can be handled by a general brazing or welding method.
したがって、本発明により、眼鏡フレームを装着した際のフィット感を向上できるだけでなく、弾性部材の張り出しやテンプルの強度低下による使用上の問題も防止することができ、しかも、製造面のハードルを下げることもできる眼鏡フレームの弾性テンプルを提供できることから、本発明の実用的価値は頗る高い。 Therefore, according to the present invention, not only can the fitting feeling when wearing the spectacle frame be improved, but also problems in use due to the overhang of the elastic member and the decrease in the strength of the temple can be prevented, and the hurdle on the manufacturing surface is lowered. Since the elastic temple of the spectacle frame can be provided, the practical value of the present invention is very high.
『実施例１』
本発明の実施例１について、図１〜図４に基いて説明する。なお同図において、符号Ｇで指示するものは、眼鏡フレームであり、符号Ｆで指示するものは、フロント枠である。また符号１で指示するものは、弾性テンプルであり、符号Ｍで指示するものは、耳掛け部である。
“Example 1”
A first embodiment of the present invention will be described with reference to FIGS. In the figure, what is indicated by the symbol G is a spectacle frame, and what is indicated by the symbol F is a front frame. Also, what is indicated by reference numeral 1 is an elastic temple, and what is indicated by reference numeral M is an ear hook.
まず実施例１では、眼鏡フレームＧのフロント枠Ｆの両側に取着する左右の弾性テンプル１・１について、弾性テンプル１の可動端に耳掛け部Ｍを設けると共に、基端側から中央までの部位を薄板状(厚さ:0.6mm)のメタル枠11で構成して、このメタル枠11の基端部にフロント枠Ｆの曲げ智にヒンジ連結するヒンジ片11aを突成している(図１、図２参照)。 First, in the first embodiment, the left and right elastic temples 1 and 1 attached to both sides of the front frame F of the spectacle frame G are provided with ear hooking portions M at the movable ends of the elastic temples 1 and from the base end side to the center. The portion is composed of a thin plate-like (thickness: 0.6 mm) metal frame 11, and a hinge piece 11a is formed at the base end portion of the metal frame 11 to be hinged to the bending force of the front frame F (see FIG. 1, see FIG.
また、上記弾性テンプル１のメタル枠11の側面には、長手方向に二つの窓部11b・11bを並設すると共に、このメタル枠11に、前記窓部11b・11bに挿入可能な二つの湾曲部12a・12aを有する板バネ材12(厚さ:0.6mm)の両端を、湾曲部12a・12a間の谷部Ｂをメタル枠11内側に配置した状態で、かつ、各湾曲部12a・12aの頂部Ｔをメタル枠11外側に配置した状態で固着して構成している。 Further, on the side surface of the metal frame 11 of the elastic temple 1, two windows 11b and 11b are juxtaposed in the longitudinal direction, and the metal frame 11 has two curves that can be inserted into the windows 11b and 11b. In a state where both ends of the leaf spring material 12 (thickness: 0.6 mm) having the portions 12a and 12a are arranged with the valley portion B between the curved portions 12a and 12a inside the metal frame 11, and the curved portions 12a and 12a The top part T is fixed and configured in a state of being arranged outside the metal frame 11.
これにより、上記構成から成る弾性テンプル１・１を図３に示すように過拡開した際、メタル枠11と一緒に板バネ材12を変形させることができるため、テンプル内側に所定大きさの付勢力を働かせることができる。そして、その付勢力は、板バネ材12の近傍に位置する耳掛け部Ｍでも充分に発揮されるため、装着時に適度なフィット感が得られる。 As a result, when the elastic temples 1 and 1 having the above-described structure are over-expanded as shown in FIG. 3, the leaf spring material 12 can be deformed together with the metal frame 11, so that a predetermined size is formed inside the temple. Energizing force can be applied. And since the biasing force is sufficiently exhibited even in the ear hooking portion M located in the vicinity of the leaf spring material 12, a suitable fit can be obtained at the time of wearing.
また、上記構成を採用することによって、図４に示すように板バネ材12の湾曲部12a・12aがメタル枠11の内側または外側方向に張り出す大きさＰを、板バネ材12の湾曲部12aの幅Ｑの約半分程度に抑えることができるため、張り出した板バネ材12によって眼鏡装着時に様々な不都合が生じることもない。 In addition, by adopting the above configuration, the size P of the bent portions 12a and 12a of the leaf spring material 12 projecting inward or outward of the metal frame 11 as shown in FIG. Since it can be suppressed to about half of the width Q of 12a, the protruding leaf spring material 12 does not cause various inconveniences when wearing glasses.
また更に、上記弾性テンプル１の基部から中央を構成する薄板状のメタル枠11については、側面に孔を開けて複数の窓部11b・11bを形成しているものの、外枠や窓部11b・11b間の仕切り部によって板材としての強度が充分に保持されているため、弾性テンプル１に曲げ方向や捻り方向の負荷がかかった場合でもメタル枠11が簡単に変形する心配はない。 Further, the thin metal frame 11 constituting the center from the base portion of the elastic temple 1 has a plurality of window portions 11b and 11b formed by making holes in the side surface, but the outer frame and the window portion 11b Since the strength as a plate material is sufficiently held by the partition portion between 11b, there is no fear that the metal frame 11 is easily deformed even when a load in the bending direction or the twisting direction is applied to the elastic temple 1.
また本実施例では、上記メタル枠11と板バネ材12の形状を、両方共にテンプル基部側からテンプル可動端側にかけて幅が狭くなる近似のテーパ形状とすることによって、弾性テンプル１の強度をより向上させている。 Further, in this embodiment, the shape of the metal frame 11 and the leaf spring material 12 is both an approximate taper shape in which the width becomes narrower from the temple base side to the temple movable end side, thereby further increasing the strength of the elastic temple 1. It is improving.
そしてまた、本実施例では、上記弾性テンプル１のメタル枠11及び板バネ材12に、βチタン材料を使用して充分なテンプル強度および付勢力が得られるようにしている。なお本実施例では、上記メタル枠11に板バネ材12を固着させる手段として、ロウ付けを採用しているが、ＴＩＧ溶接やレーザ溶接などの各種溶接法を採用することもできる。 In this embodiment, a β-titanium material is used for the metal frame 11 and the leaf spring material 12 of the elastic temple 1 so that sufficient temple strength and biasing force can be obtained. In the present embodiment, brazing is adopted as means for fixing the leaf spring material 12 to the metal frame 11, but various welding methods such as TIG welding and laser welding can also be adopted.
また更に、本実施例においては、上記弾性テンプル１の板バネ材12の側面に複数の孔部12b・12b…を設けることによって、弾性テンプル１・１を過拡開した際の弾性反発力を調節している。また、上記板バネ材12の孔部12b・12b…については、形状や配置を工夫して模様を形成することにより、眼鏡フレームＧの装飾性を高めることもできる。 Furthermore, in this embodiment, by providing a plurality of holes 12b, 12b ... on the side surface of the leaf spring material 12 of the elastic temple 1, the elastic repulsive force when the elastic temples 1, 1 are over-expanded is provided. It is adjusting. Moreover, about the hole 12b * 12b ... of the said leaf | plate spring material 12, the decorativeness of the spectacles frame G can also be improved by devising shape and arrangement | positioning and forming a pattern.
他方また、本実施例では、上記メタル枠11と板バネ材12のテンプル可動端側の固着部を保護するために、耳掛け部Ｍの表面部を構成する合成樹脂製の鞘状モダン部材13を、耳掛け部Ｍの芯部を構成するメタル枠11の先端部11cに、板バネ材12の端部を覆うように取着している。これにより、板バネ材12がメタル枠11から外れ難くなる。 On the other hand, in this embodiment, in order to protect the fixed portion of the metal frame 11 and the leaf spring material 12 on the temple movable end side, a sheath-like modern member 13 made of a synthetic resin constituting the surface portion of the ear hook portion M is used. Is attached to the tip end portion 11c of the metal frame 11 constituting the core portion of the ear hook portion M so as to cover the end portion of the leaf spring material 12. As a result, the leaf spring material 12 is unlikely to come off the metal frame 11.
また本実施例では、上記板バネ材12の端部をメタル枠のテンプル基端に固着させる際、メタル枠11の外側面に板バネ材12を固着させて、その裏側にあたるメタル枠11の内側面にヒンジ片11aを突成しているため、メタル枠11のテンプル基端側の外枠を細く形成して、窓部11bのスペースを広くとることができる。 Further, in this embodiment, when the end portion of the plate spring material 12 is fixed to the temple base end of the metal frame, the plate spring material 12 is fixed to the outer surface of the metal frame 11, and the inner side of the metal frame 11 corresponding to the back side is fixed. Since the hinge piece 11a protrudes on the side surface, the outer frame on the temple base end side of the metal frame 11 can be formed thin, and the space of the window portion 11b can be widened.
『実施例２』
本発明の実施例２について、図５及び図６に基いて説明する。この実施例２では、弾性テンプル１の板バネ材12の各湾曲部12a・12aの側面に、複数の窓部12c・12cを設け、更にこの板バネ材12よりもサイズが一回り小さく、かつ、湾曲部14aが形成された補助板バネ材14の両端を、板バネ材12の窓部12c・12cに湾曲部14aを挿入した状態でメタル枠11に固定して構成している。
“Example 2”
A second embodiment of the present invention will be described with reference to FIGS. In Example 2, a plurality of window portions 12c and 12c are provided on the side surfaces of the curved portions 12a and 12a of the leaf spring material 12 of the elastic temple 1, and the size is slightly smaller than the leaf spring material 12, and In addition, both ends of the auxiliary leaf spring material 14 on which the curved portion 14a is formed are configured to be fixed to the metal frame 11 with the curved portion 14a being inserted into the window portions 12c and 12c of the leaf spring material 12.
これにより、弾性テンプル１のメタル枠11に対して板バネ材12及び補助板バネ材13を入れ子状に取り付けることが可能となるため、テンプル拡開時の付勢力をより高めることができる。また、入れ子状となった板バネ材12と補助板バネ材13によって立体的で複雑なデザインを形成することができるため、眼鏡フレームＧの装飾性も高まる。 Accordingly, the leaf spring material 12 and the auxiliary leaf spring material 13 can be nested and attached to the metal frame 11 of the elastic temple 1, so that the urging force when the temple is expanded can be further increased. Further, since the three-dimensional and complicated design can be formed by the nested leaf spring material 12 and the auxiliary leaf spring material 13, the decorativeness of the spectacle frame G is enhanced.
『実施例３』
本発明の実施例３について、図７及び図８に基いて説明する。この実施例３では、前記基端側から中央までの部位を、比較的縦幅が小さい薄板状のメタル枠11から構成すると共に、このメタル枠11に対して、長手方向に複数の湾曲部12a・12aを有し、かつ、各湾曲部12a・12aに前記メタル枠11を挿通可能な窓部12c・12cが設けられた板バネ材12を固定して弾性テンプル１を構成している。
“Example 3”
A third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, the portion from the base end side to the center is composed of a thin metal frame 11 having a relatively small vertical width, and a plurality of curved portions 12a in the longitudinal direction with respect to the metal frame 11. The elastic temple 1 is configured by fixing a leaf spring material 12 having 12a and provided with windows 12c and 12c through which the metal frame 11 can be inserted into the curved portions 12a and 12a.
また、上記板バネ材12については、板バネ材12の両端を、隣り合う湾曲部12a・12a間の谷部Ｂをメタル枠11内側に配置した状態で、かつ、各湾曲部12a・12aの頂部Ｔをメタル枠11外側に配置した状態でメタル枠11に固定している。また本実施例では、メタル枠11に所定形状の孔部11d・11d…を設けて、模様を形成すると共にメタル枠11の弾性反発力を調整している。 Further, with respect to the leaf spring material 12, both ends of the leaf spring material 12 are arranged in a state where the valley B between the adjacent curved portions 12a and 12a is disposed inside the metal frame 11, and each of the curved portions 12a and 12a. The top portion T is fixed to the metal frame 11 in a state of being arranged outside the metal frame 11. In this embodiment, the metal frame 11 is provided with holes 11d, 11d,... Having a predetermined shape to form a pattern and to adjust the elastic repulsion force of the metal frame 11.
本発明は、概ね上記のように構成されるが、実施例に限定されるものではなく、「特許請求の範囲」の記載内において種々の変更が可能であって、例えば、弾性テンプル１のメタル枠11や板バネ材12の材料には、所定の強度および弾性反発力を有する金属材料であればβチタン以外の材料を使用することができ、具体的には、ステンレス等の鉄系合金や洋白、純チタン、α-βチタン等を採用できる。 The present invention is generally configured as described above. However, the present invention is not limited to the embodiments, and various modifications can be made within the description of “Claims”. As the material of the frame 11 and the leaf spring material 12, a material other than β titanium can be used as long as it is a metal material having a predetermined strength and elastic repulsion force. Western white, pure titanium, α-β titanium, etc. can be used.
また、弾性テンプル１のメタル枠11に形成する窓部11b・11b、及び板バネ材12に形成する窓部12c・12cの形状については、台形型や矩形型、多角形型、楕円型、異形型等から選んで自由に設計することができる。加えて、板バネ材12や補助板バネ材14の湾曲部12a・14aの形状についても同様である。 In addition, the shapes of the window portions 11b and 11b formed on the metal frame 11 of the elastic temple 1 and the window portions 12c and 12c formed on the leaf spring material 12 are trapezoidal, rectangular, polygonal, elliptical, and irregular shapes. You can design freely by selecting from molds. In addition, the same applies to the shapes of the curved portions 12a and 14a of the leaf spring material 12 and the auxiliary leaf spring material 14.
そしてまた、上記窓部11b・11bや湾曲部12a・14aの数についても、それぞれ自由に変更することができる。なお、窓部11b・11bと湾曲部12a・14aの数については、必ずしも一致させる必要はない。また、上記板バネ材12の湾曲部12a・12a間に形成される谷部Ｂは、必ずしもＶ字型の折曲げ形状である必要はなく、コ字型形状や湾曲形状であってもよい。 Further, the numbers of the window portions 11b and 11b and the curved portions 12a and 14a can be freely changed. Note that the numbers of the window portions 11b and 11b and the curved portions 12a and 14a are not necessarily matched. Further, the trough B formed between the curved portions 12a and 12a of the leaf spring material 12 does not necessarily have a V-shaped bent shape, and may have a U-shaped shape or a curved shape.
また更に、上記板バネ材12の湾曲部12a・12aに関しては、適度な付勢力を得るためにテンプル基端側の湾曲部12aの曲率を、テンプル可動端側の湾曲部12aの曲率よりも大きくすることが望ましいが、全て曲率が同じ湾曲部12a・12aを形成したり、全て曲率が異なる３以上の湾曲部を形成したりすることもできる。 Furthermore, with respect to the curved portions 12a and 12a of the leaf spring material 12, the curvature of the curved portion 12a on the temple base end side is larger than the curvature of the curved portion 12a on the temple movable end side in order to obtain an appropriate biasing force. However, it is also possible to form curved portions 12a and 12a having the same curvature, or to form three or more curved portions having different curvatures.
また、弾性テンプル１のメタル枠11については、テンプル基部側からテンプル可動端側までを全てメタル枠11によって構成することもできる。また更に、弾性テンプル１の耳掛け部Ｍについても、モダン部材Ｍを使用せずに構成することもでき、またエラストマー製のモダン部材Ｍを使用して構成することもできる。 Further, the metal frame 11 of the elastic temple 1 can be entirely constituted by the metal frame 11 from the temple base side to the temple movable end side. Furthermore, the ear hooking portion M of the elastic temple 1 can also be configured without using the modern member M, or can be configured using the elastomeric modern member M.
他方また、弾性テンプル１の補助板バネ材14に関しては、メタル枠11や板バネ材12に複数取り付けることもでき、具体的には、補助板バネ材14に更に窓部を設けて、より小型の補助板バネ材を、湾曲部を補助板バネ材14の窓部に挿入した状態で入れ子状に取り付けることもできる。 On the other hand, a plurality of auxiliary leaf spring members 14 of the elastic temple 1 can be attached to the metal frame 11 or the leaf spring member 12, and more specifically, the auxiliary leaf spring member 14 is further provided with a window portion to make it smaller. The auxiliary leaf spring material can be attached in a nested manner with the curved portion inserted into the window portion of the auxiliary leaf spring material.
また、弾性テンプル１のメタル枠11の基端部は、必ずしもフロント枠Ｆの曲げ智にヒンジ連結する必要はなく、フロント枠Ｆの両端に直接固定することもでき、その場合にはメタル枠11のヒンジ片11aを省略した構成を採用することもでき、上記何れのものも本発明の技術的範囲に属する。 Further, the base end portion of the metal frame 11 of the elastic temple 1 does not necessarily have to be hinged to the bending edge of the front frame F, and can be directly fixed to both ends of the front frame F. In this case, the metal frame 11 It is also possible to adopt a configuration in which the hinge piece 11a is omitted, and any of the above belongs to the technical scope of the present invention.
近年、眼鏡業界では、装着感とデザイン性に優れた眼鏡フレームが求められている。そのような中で、本発明の眼鏡フレームの弾性テンプルは、フレームの強度を保持したまま優れたフィット感と独創的で立体的なデザインを実現できる有用な技術であるため、その産業上の利用価値は非常に高い。 In recent years, the eyeglass industry has demanded eyeglass frames with excellent wearing feeling and design.
