Description
本開示は、眼鏡フレームに関するものである。 The present disclosure relates to spectacle frames.
従来、眼鏡フレームとして、レンズを支持するフロント部と、フロント部の両端部に蝶番を介して連結されたテンプルと、を備えたものがよく知られている。また、眼鏡フレームでは、眼鏡の装着のためにテンプルを広げた際に、フロント部が変形するとレンズに無理な応力が作用するおそれがあるため、フロント部を強固に形成し、弾性変形する部分をテンプル側に設けることが知られている（例えば、特許文献１参照）。 Conventionally, a well-known spectacle frame is provided with a front portion that supports a lens and temples that are connected to both ends of the front portion via hinges. Further, in the spectacle frame, when the temple is opened for wearing spectacles, if the front part is deformed, an unreasonable stress may be applied to the lens. Therefore, the front part is firmly formed and the elastically deformed part is formed. It is known to be provided on the temple side (see, for example, Patent Document 1).
この従来技術では、眼鏡の装着時などにテンプルの左右方向の間隔を広げることを可能とするために弾性変形を行う機能を有する部位である弾性変形部が、テンプルを支持する鎧部に設けられている。 In this conventional technique, an elastically deformed portion, which is a portion having a function of elastically deforming in order to make it possible to widen the distance between the temples in the left-right direction when wearing eyeglasses, is provided on the armor portion supporting the temple. ing.
しかしながら、上述の従来技術のように、弾性変形を行う機能を有する部位が外観に現れていると、テンプルやフロント部のデザインも、その機能部位である弾性変形部と一体性のある外観にする必要があり、その分、デザインの自由度に制約を受ける。また、弾性変形部が外観に現れることで、弾性変形部が外観に現れないものと比較して、複雑な形状の外観となる。 However, when a part having a function of elastically deforming appears in the appearance as in the above-mentioned conventional technique, the design of the temple and the front part also has an appearance integrated with the elastically deformed part which is the functional part. It is necessary, and the degree of freedom in design is restricted accordingly. Further, since the elastically deformed portion appears in the appearance, the appearance becomes a complicated shape as compared with the case where the elastically deformed portion does not appear in the appearance.
そこで、本開示は、必要な弾性機能を確保しつつ、シンプルな外観で、しかも、デザインの自由度を向上可能な眼鏡フレームを提供することを目的としている。 Therefore, an object of the present disclosure is to provide an spectacle frame having a simple appearance and an ability to improve the degree of freedom in design while ensuring the necessary elastic function.
本開示の眼鏡フレームは、レンズを支持するフロント部と、前記フロント部の左右方向端部に設けられた鎧部に蝶番を介して回動可能に連結されたテンプルと、前記蝶番の前記鎧部側の鎧部側蝶片に設けられた弾性変形部と、前記鎧部に設けられ、前記弾性変形部を収容するとともに、前記弾性変形部の弾性変形を許容する収容部と、前記鎧部側蝶片に設けられ、前記弾性変形部を覆い隠すカバー部と、を備える眼鏡フレームとした。 The spectacle frame of the present disclosure includes a front portion that supports a lens, a temple that is rotatably connected to an armor portion provided at the left-right end of the front portion via a hinge, and the armor portion of the hinge. An elastically deformed portion provided on a butterfly piece on the side of the armor portion, an accommodating portion provided on the armor portion to accommodate the elastically deformed portion and to allow elastic deformation of the elastically deformed portion, and the armor portion side. The spectacle frame was provided with a cover portion provided on the butterfly piece to cover the elastically deformed portion.
本開示の眼鏡フレームでは、弾性変形部により必要な弾性を確保可能としつつ、この機能性を有した部位である弾性変形部が収容部に収容されて外観に表れないため、シンプルな外観を得ることができる。また、弾性変形部が外観に現れないため、テンプルなどの他の部位のデザインを、弾性変形部と協調可能なデザインとする必要が無くなり、デザインの自由度が向上する。 In the spectacle frame of the present disclosure, while the required elasticity can be secured by the elastically deformed portion, the elastically deformed portion, which is a portion having this functionality, is accommodated in the accommodating portion and does not appear in the appearance, so that a simple appearance is obtained. be able to. Further, since the elastically deformed portion does not appear in the appearance, it is not necessary to design the other part such as the temple so as to be able to cooperate with the elastically deformed portion, and the degree of freedom in design is improved.

The direction along the arrow RR is rearward, the direction along the arrow UP is upward, and the direction along the arrow DN is downward.
鎧部１３には、左右方向の両端部に、収容部１３１が形成され、この収容部１３１にテンプル２０の基端部が連結されている。以下に、この連結構造について説明する。 The armor portion 13 is formed with accommodating portions 131 at both ends in the left-right direction, and the base end portions of the temple 20 are connected to the accommodating portions 131. This connection structure will be described below.
図３の断面図に示すように、収容部１３１は、鎧部１３の左右方向の端縁部と、前縁部から水平方向の内側に凹状に略Ｌ字状に形成され、前後方向の中間には、支持壁１３２が立設されている。 As shown in the cross-sectional view of FIG. 3, the accommodating portion 131 is formed in a substantially L-shape in a concave shape inward in the horizontal direction from the left-right end edge portion of the armor portion 13 and the front edge portion, and is intermediate in the front-rear direction. A support wall 132 is erected in the building.
支持壁１３２は、図３に示すように、収容部１３１を前後に仕切って左右方向に延びる縦壁状に形成され、前面にボス部嵌合溝１３３が形成され、後面に座金嵌合溝１３４が形成されている。ボス部嵌合溝１３３は、後述する弾性変形部３１２のボス部３１２ｃを嵌め合わせ可能に、正面から見て円形の穴状に形成されている。座金嵌合溝１３４は、後述する平座金４１を嵌め合わせ可能な左右に延びる浅い溝状に形成されている。 As shown in FIG. 3, the support wall 132 is formed in the shape of a vertical wall extending in the left-right direction by partitioning the accommodating portion 131 back and forth, the boss portion fitting groove 133 is formed on the front surface, and the washer fitting groove 134 is formed on the rear surface. Is formed. The boss portion fitting groove 133 is formed in a circular hole shape when viewed from the front so that the boss portion 312c of the elastically deformed portion 312 described later can be fitted. The washer fitting groove 134 is formed in a shallow groove shape extending to the left and right so that the flat washer 41 described later can be fitted.
次に、テンプル２０および蝶番３０について説明する。
テンプル２０は、金属製（例えば、純チタン製）であり、周知のように棒状に形成され、フロント部１０側の基端部が、蝶番３０を介して収容部１３１の支持壁１３２に連結されている。
Next, the temple 20 and the hinge 30 will be described.
The temple 20 is made of metal (for example, made of pure titanium), is formed in a rod shape as is well known, and the base end portion on the front portion 10 side is connected to the support wall 132 of the accommodating portion 131 via a hinge 30. ing.
蝶番３０は、テンプル２０が折り畳まれた状態と、図１Ａに示すように、左右に間隔を空けて開いた状態（装着時の状態）とに回転変位可能に、テンプル２０をフロント部１０に連結するもので、鎧部側蝶片３１と、テンプル側蝶片３２と、回転軸３３とを備える。 The hinge 30 connects the temple 20 to the front portion 10 so that the temple 20 can be rotationally displaced between the folded state and the open state (when mounted) with a space between the left and right sides as shown in FIG. 1A. The hinge piece 31 on the armor side, the hinge piece 32 on the temple side, and the rotation shaft 33 are provided.
鎧部側蝶片３１は、詳細は後述するが、鎧部１３に取り付けられており、回転軸３３を挿し通す管状部が内側に突出して形成されている。テンプル側蝶片３２は、テンプル２０の棒状の本体２１と一体に形成され、回転軸３３を挿し通す管状部が内側に突出して形成されている。すなわち、回転軸３３は、鎧部側蝶片３１の管状部と、テンプル側蝶片３２の管状部とに挿通されて、両者の相対回転を可能に連結する。 Although the details of the butterfly piece 31 on the armor portion side will be described later, the butterfly piece 31 is attached to the armor portion 13, and a tubular portion through which the rotation shaft 33 is inserted protrudes inward. The temple-side butterfly piece 32 is integrally formed with the rod-shaped main body 21 of the temple 20, and a tubular portion through which the rotating shaft 33 is inserted protrudes inward. That is, the rotation shaft 33 is inserted through the tubular portion of the armor side butterfly piece 31 and the tubular portion of the temple side butterfly piece 32 to enable relative rotation of both.
鎧部側蝶片３１は、図３に示すように、蝶片本体３１１と、蝶片本体３１１から装着時の頭部の方向に分岐して突出された弾性変形片３１２と、蝶片本体３１１を延長し、図３において内側に湾曲されたカバー部３１３と、を備える。 As shown in FIG. 3, the armor-side butterfly piece 31 includes a butterfly piece main body 311, an elastic deformed piece 312 branched from the butterfly piece main body 311 toward the head when attached, and a butterfly piece main body 311. Is provided with a cover portion 313 that is curved inward in FIG.
また、蝶片本体３１１には、回転軸３３の近傍にフロント側ストッパ面３１１ｓが形成されている。このフロント側ストッパ面３１１ｓは、テンプル２０を、折り畳み状態から開いた際に、テンプル側蝶片３２に形成されたテンプル側ストッパ面３２ｓと突き当たり状態となってテンプル２０が図１Ａの位置からさらに外側に回転するのを規制する。 Further, the butterfly piece main body 311 is formed with a front stopper surface 311s in the vicinity of the rotation shaft 33. When the temple 20 is opened from the folded state, the front stopper surface 311s comes into contact with the temple side stopper surface 32s formed on the temple side butterfly piece 32, and the temple 20 is further outside from the position of FIG. 1A. Regulate the rotation to.
弾性変形片３１２は、弾性変形部として設けられたもので、蝶片本体３１１に結合された基部３１２ａと、基部３１２ａから湾曲状に延びる湾曲部３１２ｂと、湾曲部３１２ｂの先端に湾曲の内側方向に凸状に突出されたボス部３１２ｃとを備える。 The elastically deformed piece 312 is provided as an elastically deformed part, and has a base portion 312a coupled to the butterfly piece main body 311, a curved portion 312b extending in a curved shape from the base portion 312a, and a curved inward direction at the tip of the curved portion 312b. It is provided with a boss portion 312c protruding in a convex shape.
湾曲部３１２ｂは、蝶片本体３１１との間に間隔を空けて配置され、かつ、湾曲の内周を装着時に頭部の方向となる内側に向けた湾曲状に形成されている。この湾曲部３１２ｂは、テンプル２０を、両ストッパ面３２ｓ、３１１ｓにより開き方向の回転を規制された状態からさらにテンプル２０、２０の間隔を広げた際に弾性変形を行う部位である。そして、湾曲部３１２ｂは、この湾曲部３１２ｂの材質、厚さ、長さ、湾曲度等に基づいて、あらかじめ設定された適切な弾性が与えられている。なお、弾性変形を行う部位を湾曲形状の湾曲部３１２ｂとしたことにより、弾性変形を行う部位を直線状に形成した場合よりも、左右方向や前後方向に必要な寸法を抑えることができる。 The curved portion 312b is arranged at a distance from the butterfly piece main body 311 and is formed in a curved shape with the inner circumference of the curved portion facing inward toward the head when worn. The curved portion 312b is a portion that elastically deforms the temple 20 when the distance between the temples 20 and 20 is further widened from the state in which the rotation in the opening direction is restricted by the stopper surfaces 32s and 311s. The curved portion 312b is given appropriate elasticity set in advance based on the material, thickness, length, degree of curvature, and the like of the curved portion 312b. Since the portion to be elastically deformed is the curved portion 312b having a curved shape, it is possible to suppress the required dimensions in the left-right direction and the front-back direction as compared with the case where the portion to be elastically deformed is formed in a straight line.
ボス部３１２ｃは、中心軸を前後方向に向けた円柱状に形成され、かつ、フロント部１０の収容部１３１に設けられた支持壁１３２のボス部嵌合溝１３３に嵌り合う直径寸法に形成され、かつ、後側の端面に開口を有するねじ穴（図示省略）が設けられている。このねじ穴は、蝶番３０を固定するねじ４０を締結可能に形成されている。 The boss portion 312c is formed in a columnar shape with the central axis directed in the front-rear direction, and has a diameter dimension that fits into the boss portion fitting groove 133 of the support wall 132 provided in the accommodating portion 131 of the front portion 10. In addition, a screw hole (not shown) having an opening is provided on the rear end surface. This screw hole is formed so that a screw 40 for fixing the hinge 30 can be fastened.
また、湾曲部３１２ｂおよびボス部３１２ｃの上下方向の寸法は、収容部１３１の上下方向寸法よりも僅かに小さな寸法に形成され、図４Ａにも示すように、収容部１３１に収容され、ボス部３１２ｃが収容部１３１に固定されている。 Further, the vertical dimensions of the curved portion 312b and the boss portion 312c are formed to be slightly smaller than the vertical dimensions of the accommodating portion 131, and as shown in FIG. 4A, they are accommodated in the accommodating portion 131 and the boss portion. The 312c is fixed to the accommodating portion 131.
この弾性変形片３１２の固定構造を図３により説明すると、ボス部３１２ｃを収容部１３１の支持壁１３２の前面に形成されたボス部嵌合溝１３３に嵌合させる。そして、支持壁１３２の後面に形成された座金嵌合溝１３４に平座金４１を嵌め合わせた状態として、ねじ４０を平座金４１の後方から、平座金４１および支持壁１３２を貫通させて、ボス部３１２ｃのねじ穴に締結して固定されている（図４Ａ参照）。 Explaining the fixing structure of the elastic deformed piece 312 with reference to FIG. 3, the boss portion 312c is fitted into the boss portion fitting groove 133 formed on the front surface of the support wall 132 of the accommodating portion 131. Then, with the flat washer 41 fitted in the washer fitting groove 134 formed on the rear surface of the support wall 132, the screw 40 is passed through the flat washer 41 and the support wall 132 from behind the flat washer 41 to boss. It is fastened and fixed to the screw hole of the portion 312c (see FIG. 4A).
カバー部３１３は、弾性変形片３１２の湾曲部３１２ｂに対し、装着時に前方となる方向に間隔を空けて配置され、かつ、湾曲部３１２ｂに沿うように湾曲されている。そして、カバー部３１３は、眼鏡フレームＡを前方から見た際に、弾性変形片３１２がカバー部３１３に隠れるように、その上下方向寸法が弾性変形片３１２の上下方向寸法以上の寸法に形成されている。さらに、カバー部３１３の上下方向寸法は、収容部１３１の上下方向寸法よりも、僅かに小さな寸法に形成されており、後述するようにカバー部３１３が収容部１３１に進入可能に形成されている。加えて、カバー部３１３を含む鎧部側蝶片３１は、テンプル側蝶片３２およびテンプル２０の本体２１と一体的な外観を成すように形成されている。 The cover portion 313 is arranged with a space in the direction toward the front when mounted with respect to the curved portion 312b of the elastic deformed piece 312, and is curved along the curved portion 312b. The cover portion 313 is formed so that the elastically deformed piece 312 is hidden behind the cover portion 313 when the eyeglass frame A is viewed from the front, and the vertical dimension thereof is equal to or larger than the vertical dimension of the elastically deformed piece 312. ing. Further, the vertical dimension of the cover portion 313 is formed to be slightly smaller than the vertical dimension of the accommodating portion 131, and the cover portion 313 is formed so as to be able to enter the accommodating portion 131 as described later. .. In addition, the armor side butterfly piece 31 including the cover part 313 is formed so as to form an integral appearance with the temple side butterfly piece 32 and the main body 21 of the temple 20.
（実施の形態１の作用）
次に、実施の形態１の作用を説明する。
実施の形態１の眼鏡フレームＡを装着する際には、テンプル２０、２０を耳に掛けるが、この際、テンプル２０、２０同士の間隔を水平方向に一旦広げる場合がある。この場合、蝶番３０の湾曲部３１２ｂを弾性変形させることで、テンプル２０がボス部３１２ｃを支点として、左右方向に変位して相互の間隔を広げる。図１Ｂは、このようにテンプル２０、２０の間隔を左右方向に広げた状態を示しており、テンプル２０、２０の本体２１、２１を殆ど弾性変形することなく、相互の間隔を広げることができる。
(Action of Embodiment 1)
Next, the operation of the first embodiment will be described.
When wearing the spectacle frame A of the first embodiment, the temples 20 and 20 are hung on the ears, and at this time, the distance between the temples 20 and 20 may be temporarily widened in the horizontal direction. In this case, by elastically deforming the curved portion 312b of the hinge 30, the temple 20 is displaced in the left-right direction with the boss portion 312c as a fulcrum to widen the mutual distance. FIG. 1B shows a state in which the distance between the temples 20 and 20 is widened in the left-right direction, and the distance between the temples 20 and 20 can be widened with almost no elastic deformation. ..
このように、テンプル２０を外側に広げた際の湾曲部３１２ｂおよびカバー部３１３の動きについて、図４Ａ、図４Ｂに基づいて説明する。 As described above, the movements of the curved portion 312b and the cover portion 313 when the temple 20 is expanded outward will be described with reference to FIGS. 4A and 4B.
図４Ａは、図１Ａに示すように、テンプル２０、２０を装着時の状態であって、両ストッパ面３１１ｓ、３２ｓにより回動規制されるまで開いたときの蝶番３０付近の構造を示す。この状態からさらにテンプル２０を外側に広げる際に弾性変形する湾曲部３１２ｂは、収容部１３１に収容されており、外観に殆ど現れない。また、収容部１３１の開口部分である収容部１３１の前方の開口および左右方向の開口は、図２に示すようにカバー部３１３に覆い隠されている。 As shown in FIG. 1A, FIG. 4A shows a structure in the vicinity of the hinge 30 when the temples 20 and 20 are mounted and opened until rotation is restricted by both stopper surfaces 311s and 32s. The curved portion 312b, which elastically deforms when the temple 20 is further expanded outward from this state, is housed in the housing portion 131 and hardly appears in the appearance. Further, the front opening and the left-right opening of the accommodating portion 131, which is the opening portion of the accommodating portion 131, are covered by the cover portion 313 as shown in FIG.
したがって、弾性変形部である弾性変形片３１２が外観に現れる場合と比較して、すっきりしてシンプルな外観を得ることができる。また、テンプル２０のデザインも、弾性変形片３１２とマッチするようなデザインに制約されることがなく、高い設計自由度を得ることができる。 Therefore, a neat and simple appearance can be obtained as compared with the case where the elastically deformed piece 312, which is the elastically deformed portion, appears in the appearance. Further, the design of the temple 20 is not restricted to a design that matches the elastic deformed piece 312, and a high degree of design freedom can be obtained.
次に、図４Ｂは、湾曲部３１２ｂをテンプル２０、２０の間隔を外側に広げた場合（図１Ｂに示す状態）の蝶番３０を示す。テンプル２０、２０の間隔を外側に広げた場合、テンプル２０は、図４Ａの状態から、弾性変形片３１２の湾曲部３１２ｂがその湾曲の弧を広げるように弾性変形し、この湾曲部３１２ｂを中心に、時計回り方向に回転変位する。そして、テンプル２０が変位するのに伴い、カバー部３１３が鎧部１３と干渉することなく収容部１３１に進入する。なお、テンプル２０およびカバー部３１３の変位は、カバー部３１３の先端部が弾性変形片３１２のボス部３１２ｃに突き当たると、それ以上の変位が規制される。なお、図４Ａ、図４Ｂは、フロント部１０の左側端部を示しているが、フロント部１０の右側端部も、図４Ａ、図４Ｂと左右対称の動きとなる。 Next, FIG. 4B shows the hinge 30 when the curved portion 312b is widened outward from the temples 20 and 20 (the state shown in FIG. 1B). When the distance between the temples 20 and 20 is widened outward, the temple 20 is elastically deformed from the state of FIG. 4A so that the curved portion 312b of the elastically deformed piece 312 widens the arc of the curvature, and the temple 20 is centered on the curved portion 312b. In addition, it is rotationally displaced in the clockwise direction. Then, as the temple 20 is displaced, the cover portion 313 enters the accommodating portion 131 without interfering with the armor portion 13. As for the displacement of the temple 20 and the cover portion 313, further displacement is restricted when the tip portion of the cover portion 313 abuts on the boss portion 312c of the elastic deformation piece 312. Although FIGS. 4A and 4B show the left end portion of the front portion 10, the right end portion of the front portion 10 also moves symmetrically with FIGS. 4A and 4B.
以上のように、湾曲部３１２ｂを覆い隠すカバー部３１３をフロント部１０の鎧部１３の外周縁に沿うように配置していても、フロント部１０と干渉することなく収容部１３１に進入するため、テンプル２０の回転変位を円滑に行うことができる。また、このカバー部３１３の移動量は僅か（例えば、１〜２ｍｍ程度）であり、かつ、カバー部３１３と収容部１３１の上下縁との寸法差が僅か（０．１〜０．２ｍｍ程度）であるため、カバー部３１３の移動が、装着者に違和感を与えることも無い。 As described above, even if the cover portion 313 that covers the curved portion 312b is arranged along the outer peripheral edge of the armor portion 13 of the front portion 10, it enters the accommodating portion 131 without interfering with the front portion 10. , The rotational displacement of the temple 20 can be smoothly performed. Further, the amount of movement of the cover portion 313 is small (for example, about 1 to 2 mm), and the dimensional difference between the cover portion 313 and the upper and lower edges of the accommodating portion 131 is small (about 0.1 to 0.2 mm). Therefore, the movement of the cover portion 313 does not give a sense of discomfort to the wearer.
以下に、実施の形態１の眼鏡フレームＡの効果を列挙する。
（１）実施の形態１の眼鏡フレームＡは、レンズ１００、１００を支持するフロント部１０と、フロント部１０の左右方向端部に設けられた鎧部１３に蝶番３０を介して回動可能に連結されたテンプル２０と、を備える。さらに、蝶番３０の鎧部側の鎧部側蝶片３１に設けられた弾性変形片３１２と、鎧部１３に設けられ、弾性変形片３１２を収容するとともに、弾性変形片３１２の弾性変形を許容する収容部１３１と、鎧部側蝶片３１に設けられ、弾性変形片３１２を覆い隠すカバー部３１３と、を備える。
The effects of the spectacle frame A of the first embodiment are listed below.
(1) The spectacle frame A of the first embodiment can be rotated through a hinge 30 to a front portion 10 that supports the lenses 100, 100 and an armor portion 13 provided at the left-right end portion of the front portion 10. It includes a connected temple 20 and.

（５）実施の形態１の眼鏡フレームＡは、フロント部１０の鎧部１３が樹脂製である。
したがって、金属製のものと比較して収容部１３１の加工を容易に行うことができる。
(5) In the spectacle frame A of the first embodiment, the armor portion 13 of the front portion 10 is made of resin.
Therefore, the processing of the accommodating portion 131 can be easily performed as compared with the metal one.
（６）実施の形態１の眼鏡フレームＡは、蝶番３０およびテンプル２０が金属製である。
したがって、テンプル２０を回転が規制された状態から外側に広げる際に、テンプル２０への入力を蝶番３０の弾性変形片３１２に確実に伝達して、弾性変形片３１２を弾性変形させることができる。また、蝶番３０およびテンプル２０を金属製とし、上記（５）のようにフロント部１０を樹脂製としたものでも、上記（２）のようにカバー部３１３が収容部１３１に進入して鎧部１３等と干渉しないため、樹脂製の鎧部１３が傷付いたり破損したりすることがない。
(6) In the spectacle frame A of the first embodiment, the hinge 30 and the temple 20 are made of metal.
Therefore, when the temple 20 is expanded outward from the state where the rotation is restricted, the input to the temple 20 can be reliably transmitted to the elastically deformed piece 312 of the hinge 30, and the elastically deformed piece 312 can be elastically deformed. Further, even if the hinge 30 and the temple 20 are made of metal and the front portion 10 is made of resin as in (5) above, the cover portion 313 enters the accommodating portion 131 as in (2) above and the armor portion. Since it does not interfere with the 13 and the like, the resin armor 13 is not damaged or damaged.
