Description

本発明は、眼鏡のテンプル連結構造及び眼鏡フレームに関し、詳しくは、簡単にがたつき無く連結することができる眼鏡のテンプル連結構造及び眼鏡フレームに関する。   The present invention relates to a temple connecting structure for eyeglasses and an eyeglass frame, and more particularly to a temple connecting structure for eyeglasses and an eyeglass frame that can be easily connected without rattling.

眼鏡のフィット感を向上するために、弾性体を用いてテンプルが開いた状態から外方向へ僅かに押し開くことができるテンプル連結構造がある。特に近年では、簡単な構成とすることができ組み込みや修理を容易に行うことができる板バネを用いたテンプル連結構造が種々提案されている。このようなテンプル連結構造は、少なくとも板バネの一端をテンプル及びヨロイのいずれか一方に固定し、板バネの他端をテンプル又はヨロイのいずれか他方に当接又は固定している。そして、テンプルが開いた状態のときに更にテンプルを外方向に押し開くと、板バネが弾性変形して装着者の顔側面から頭部にかけてテンプルがフィットする構成である。   In order to improve the fit of the glasses, there is a temple connection structure that can be slightly pushed outward from the state where the temple is opened using an elastic body. Particularly in recent years, various temple connection structures using leaf springs have been proposed that can be simply configured and can be easily assembled and repaired. In such a temple connection structure, at least one end of the leaf spring is fixed to one of the temple and the alloy, and the other end of the leaf spring is in contact with or fixed to either the temple or the alloy. When the temple is further opened in the open state, the leaf spring is elastically deformed to fit the temple from the wearer's face side to the head.

板バネをヨロイ又はテンプルに固定する方法としては、例えば図11に示すように、ヨロイ101に形成された空間102に板バネ103の一部を挿入し、板バネ103一端に形成されたネジ孔にネジ101を挿入して固定するもの(例えば特許文献1)が挙げられる。また、例えば図12に示すように、予めヨロイ101の端部に板バネ103を一体成形したもの(例えば特許文献2)が挙げられる。

As a method for fixing the leaf spring to the armor or temple, for example, as shown in FIG. 11, a part of the leaf spring 103 is inserted into a space 102 formed in the armor 101 and a screw hole formed at one end of the leaf spring 103. (For example, patent document 1) which inserts and fixes the screw | thread 101 to this is mentioned. Further, for example, as shown in FIG. 12, a member in which a leaf spring 103 is integrally formed in advance on the end portion of the end piece 101 (for example, Patent Document 2) may be used.
JP 2007-74540 A JP 2006-217545 A

しかし、ヨロイに設けられた空間に板バネを挿入してネジで固定する構成の場合、ネジで一箇所固定するだけであると、空間内で板バネがネジ軸と垂直方向にがたつく虞がある。一方、ネジで複数箇所固定する場合には、余分なスペースが必要となるので眼鏡フレームのデザインが制限される。また、テンプル又はヨロイの端部に板バネを一体成形した場合には、板バネが故障したような場合に板バネのみを取り替えることができないので、修理や部品交換が困難となる。   However, in the case of a configuration in which a leaf spring is inserted into a space provided in the armor and is fixed with a screw, if the plate spring is only fixed at one place, the leaf spring may rattle in the direction perpendicular to the screw shaft in the space. . On the other hand, when a plurality of positions are fixed with screws, an extra space is required, which limits the design of the spectacle frame. Further, when a leaf spring is integrally formed at the end of the temple or armor, only the leaf spring cannot be replaced in the event that the leaf spring breaks down, making it difficult to repair or replace parts.

そこで、本発明は板バネががたつくこと無く固定することができ、容易に板バネのみを交換することができる眼鏡のテンプル連結構造及び眼鏡フレームを提供することを目的とする。   Therefore, an object of the present invention is to provide a temple connecting structure for eyeglasses and an eyeglass frame in which the leaf spring can be fixed without rattling, and only the leaf spring can be easily replaced.

上記目的を達成するために、請求項1に記載の眼鏡のテンプル連結構造は、レンズを嵌め込んだフロントフレームの両側に形成され、一方に開口したヨロイ溝がそれぞれ形成されたヨロイと、前記ヨロイ溝に一部が収納されて前記ヨロイ溝の奥の壁部に当接する板バネと、前記板バネに回動可能に連結されたテンプルと、開口端がテーパー状に尖って形成されており、前記ヨロイに形成されたバネ止め孔に挿入される前記バネ止め孔の内径と略同一の外径の袋ナットと、該袋ナットに螺合して、前記バネ止め孔に挿入されるボルトと、を備え、前記板バネは前記ヨロイに収納される部分に前記ボルトが挿通される係止孔を有しており、前記板バネを前記ヨロイ溝に収納したときに、前記係止孔の軸芯は前記バネ止め孔の軸芯よりも前記壁部と反対方向にずれて位置し、前記板バネは前記袋ナットに当接して固定されることを特徴としている。   In order to achieve the above object, a temple connecting structure for eyeglasses according to claim 1 is formed on both sides of a front frame into which a lens is fitted, and an armor in which armored grooves opened on one side are respectively formed, A leaf spring that is partly housed in the groove and abuts against the wall portion at the back of the Yoroi groove, a temple that is rotatably connected to the leaf spring, and an opening end that is tapered and formed, A cap nut having an outer diameter substantially the same as the inner diameter of the spring stop hole inserted into the spring stop hole formed in the armor, a bolt inserted into the cap nut and inserted into the spring stop hole; The leaf spring has a latching hole through which the bolt is inserted in a portion accommodated in the armor, and when the leaf spring is accommodated in the armored groove, the shaft core of the latching hole is provided. Is the wall portion rather than the axial center of the spring retaining hole. Located displaced in pairs direction, the plate spring is characterized by being fixed in contact with the cap nut.

請求項2に記載の眼鏡のテンプル連結構造は、一端がテーパー状に尖った円筒状であって、前記ボルトが挿通されるワッシャーを更に備え、前記ヨロイには2つのヨロイ溝が形成されるとともに、前記2つのヨロイ溝にそれぞれ前記板バネの一部が収納され、前記板バネを前記2つのヨロイ溝にそれぞれ収納したときに、各板バネに形成された係止孔の軸芯は前記バネ止め孔の軸芯よりも前記壁部と反対方向にずれて位置し、前記2枚の板バネは前記袋ナットと前記ワッシャーとで挟着されることを特徴としている。   The temple connecting structure for eyeglasses according to claim 2 is a cylindrical shape with one end tapered, and further comprises a washer through which the bolt is inserted, and the armor is formed with two armored grooves. A part of the leaf spring is housed in each of the two armature grooves, and when the leaf spring is housed in each of the two armor grooves, the axis of the locking hole formed in each leaf spring is the spring. The two leaf springs are sandwiched between the cap nut and the washer, and are positioned so as to be shifted in the opposite direction to the wall portion with respect to the axial center of the retaining hole.

請求項3に記載の眼鏡のテンプル連結構造は、前記板バネは、前記ヨロイ溝に収納されて前記ヨロイにネジ固定される係止孔を有する基部と、前記基部から延びるとともに前記ヨロイ溝奥の壁部に当接する当接部と、前記基部から延びて前記テンプルの端部に回動可能に連結されるとともに所定範囲で弾性変形可能な弾性部と、により構成され、前記弾性部は、眼鏡の外側方向に弾性変形した状態で、その先端が前記当接部の先端に掛止されることを特徴としている。   The temple connecting structure for eyeglasses according to claim 3, wherein the leaf spring is housed in the armored groove and has a base part having a locking hole that is screwed to the armory, and extends from the base part and at the back of the armored groove. An abutting portion that abuts against the wall portion, and an elastic portion that extends from the base portion and is rotatably connected to an end portion of the temple and is elastically deformable within a predetermined range. The front end of the contact portion is hooked to the front end of the abutting portion in a state of being elastically deformed in the outward direction.

請求項4に記載の眼鏡フレームは、請求項1から請求項3のいずれかに記載の眼鏡のテンプル連結構造を用いたことを特徴としている。   According to a fourth aspect of the present invention, the eyeglass frame uses the temple connecting structure for eyeglasses according to any one of the first to third aspects.

本発明の請求項1によると、袋ナットの外径はバネ止め孔の内径と略同一であるので、袋ナットをバネ止め孔に挿入したときに袋ナットの軸芯とバネ止め孔の軸芯はほぼ同一となる。そして、係止孔の軸芯はバネ止め孔の軸芯よりも壁部と反対方向にずれて位置しているので、バネ止め孔に挿入された袋ナットはテーパー状に尖った端部の壁部方向側が係止孔に当接する。したがって、袋ナットにボルトを螺合させて板バネを挟持するとき袋ナットのボルト方向への力は係止孔の壁部方向の力に変換される。したがって、板バネは、ヨロイ溝の奥の壁部に当接されているので、このような係止孔の壁部方向の力により、板バネはより強固に壁部に当接されることとなり、板バネがヨロイに強固に固定されることになる。したがって、板バネがヨロイに対してがたつくことを抑制することができる。   According to the first aspect of the present invention, since the outer diameter of the cap nut is substantially the same as the inner diameter of the spring retaining hole, the shaft core of the cap nut and the shaft center of the spring retaining hole when the cap nut is inserted into the spring retaining hole. Are almost identical. Since the shaft core of the locking hole is located in a direction opposite to the wall portion with respect to the shaft core of the spring retaining hole, the cap nut inserted into the spring retaining hole has a tapered end wall. The part direction side comes into contact with the locking hole. Therefore, when the bolt is screwed into the cap nut and the leaf spring is clamped, the force of the cap nut in the bolt direction is converted into the force in the direction of the wall portion of the locking hole. Therefore, since the leaf spring is in contact with the wall portion at the back of the yoro groove, the leaf spring is more firmly in contact with the wall portion due to the force in the wall portion direction of the locking hole. The leaf spring is firmly fixed to the armor. Therefore, it can suppress that a leaf | plate spring rattles with respect to an armor.

請求項2によると、ヨロイに2つの溝が形成されるとともに、2つの溝にそれぞれ板バネの一部が収納され、2枚の板バネはボルトに螺合する袋ナットとボルトが挿通されるワッシャーとにより挟着される。係止孔の軸芯はバネ止め孔の軸芯よりも壁部と反対方向にずれて位置しているので、バネ止め孔に挿入された袋ナット及びワッシャーはテーパー状に尖った端部の壁部方向が係止孔に当接する。したがって、袋ナット及びワッシャーにボルトを螺合させて板バネを挟持するとき袋ナットのボルト方向への力は係止孔の眼鏡の壁部方向の力に変換される。板バネは、ヨロイ溝の奥の壁部に当接されているので、このような係止孔の壁部方向の力により、板バネはより強固に壁部に当接されて、ヨロイに強固に固定されることになる。したがって、板バネがヨロイに対してがたつくことを抑制することができる。   According to the second aspect of the present invention, two grooves are formed in the armor and a part of the leaf spring is accommodated in each of the two grooves, and the two leaf springs are inserted with a cap nut and a bolt that are screwed into the bolt. It is clamped by a washer. Since the shaft core of the locking hole is located in a direction opposite to the wall portion than the shaft core of the spring retaining hole, the cap nut and washer inserted into the spring retaining hole have a tapered end wall. The part direction contacts the locking hole. Therefore, when the bolt is screwed onto the cap nut and the washer to clamp the leaf spring, the force of the cap nut in the bolt direction is converted to the force of the locking hole in the direction of the wall of the glasses. Since the leaf spring is in contact with the wall portion at the back of the armored groove, the force in the direction of the wall portion of the locking hole causes the leaf spring to be in contact with the wall portion more firmly and strongly against the armor. It will be fixed to. Therefore, it can suppress that a leaf | plate spring rattles with respect to an armor.

本願の請求項3に記載の発明によると、板バネは基部と当接部と弾性部とにより構成されており、基部に設けられた係止孔でヨロイにネジ固定されるとともに、当接部がヨロイ溝奥の壁部に当接する。このように弾性変形する弾性部とは別に当接部を設けたことで、眼鏡のテンプルを押し広げて板バネを弾性変形させたときでも、当接部がヨロイ溝奥の壁部に当接した状態を保つことができるので、板バネがヨロイに対してがたつくことを更に抑制できる。   According to the invention described in claim 3 of the present application, the leaf spring is configured by the base portion, the contact portion, and the elastic portion, and is screwed to the armor by the locking hole provided in the base portion, and the contact portion. Comes into contact with the wall at the back of the groove. By providing an abutting portion separately from the elastic portion that is elastically deformed in this way, the abutting portion abuts against the wall portion at the back of the yoro groove, even when the temples of the glasses are expanded and the leaf spring is elastically deformed. Therefore, it is possible to further suppress the leaf spring from rattling against the armor.

また、弾性部は、眼鏡の外側方向に弾性変形した状態でその先端が前記当接部の先端に掛止されるので、弾性部には常に眼鏡の内側方向への復元力が維持されたまま当接部先端に掛止されることとなる。このように構成されることで、弾性部に眼鏡の外側方向への所定未満の弱い力が加わったとしても内側方向への復元力があるので外側方向に弾性変形することはない。そして、弾性部は、内側方向への復元力以上の力が外側方向に加わった場合のみ弾性変形することができる。したがって、板バネが不必要に弾性変形することを防ぐことができ、テンプルが不必要に揺れることを防ぐことができる。   Further, since the elastic portion is elastically deformed in the outer direction of the glasses, the tip thereof is hooked on the tip of the contact portion, so that the restoring force in the inner direction of the glasses is always maintained in the elastic portion. It will be hooked at the tip of the contact part. By being configured in this manner, even if a less than predetermined weak force in the outer direction of the spectacles is applied to the elastic portion, there is a restoring force in the inner direction, so that it does not elastically deform in the outer direction. The elastic portion can be elastically deformed only when a force equal to or greater than the restoring force in the inner direction is applied in the outer direction. Therefore, the leaf spring can be prevented from elastically deforming unnecessarily, and the temple can be prevented from unnecessarily shaking.

本願の請求項4に記載のメガネフレームは、請求項1から請求項3のいずれかに記載の眼鏡テンプル連結構造を用いているので、上述のいずれかの効果を有する眼鏡フレームとすることができる。   The eyeglass frame according to claim 4 of the present application uses the eyeglass temple connecting structure according to any one of claims 1 to 3, and therefore can be an eyeglass frame having any of the above-described effects. .

以下、本発明に係る眼鏡のテンプル連結構造1及び眼鏡フレーム2の最良の実施形態について、図面を参照しつつ説明する。   BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, best embodiments of a temple connecting structure 1 and a spectacle frame 2 according to the present invention will be described with reference to the drawings.

眼鏡フレーム2は、図1に示すように、眼鏡の前面であるフロントフレーム3と、フロントフレーム3の両端にフロントフレーム3と一体に形成されるヨロイ4と、フロントフレーム3に折り畳み可能なテンプル5と、ヨロイ4にテンプルを連結する板バネ6と、を含む構成である。   As shown in FIG. 1, the spectacle frame 2 includes a front frame 3 that is the front surface of spectacles, an armor 4 formed integrally with the front frame 3 at both ends of the front frame 3, and a temple 5 that can be folded on the front frame 3. And a leaf spring 6 for connecting the temple to the armor 4.

フロントフレーム3は、例えばアセテート等の合成樹脂により形成されており、その両端にはヨロイ4が一体形成されている。なお、フロントフレーム3の材質は合成樹脂に限られるものではなく、例えばチタン等の金属で形成されても良い。ヨロイ4は、図2に示すように、内側に開口する2本のヨロイ溝41が形成されており、このヨロイ溝41には板バネ6が一部をテンプル5側に突出させた状態で収納される。また、図示されていないがヨロイ4下側には板バネ6をネジ固定することができるように、バネ止め孔42が開けられている。   The front frame 3 is formed of a synthetic resin such as acetate, for example, and the end piece 4 is integrally formed at both ends thereof. The material of the front frame 3 is not limited to synthetic resin, and may be formed of a metal such as titanium. As shown in FIG. 2, the armor 4 is formed with two armor grooves 41 that open to the inside, and the leaf spring 6 is stored in the armor groove 41 with a part of the leaf spring 6 protruding toward the temple 5. Is done. Although not shown, a spring retaining hole 42 is formed below the armor 4 so that the leaf spring 6 can be screwed.

なお、本実施形態において、内側とは眼鏡を装着したときに眼鏡の装着者側となる方向をいい、外側とは眼鏡を装着したときに眼鏡の装着者と反対側となる方向をいう。   In the present embodiment, the inner side refers to the direction on the side of the spectacles wearer when wearing spectacles, and the outer side refers to the direction on the side opposite to the spectacles wearer when wearing spectacles.

テンプル5は、フロントフレーム3と同様に例えばアセテート等の合成樹脂で形成された長尺の部材であり、連結側端部に設けられた突片51が連結軸7に外嵌して板バネ6に回動可能に係着することができる。なお、テンプル5の材質は合成樹脂に限られるものではなく、例えばチタン等の金属で形成されても良い。板バネ6は、図3に示すように、係止孔61が設けられた基部62と、基部62から伸びておりヨロイ溝41に収納されたときにヨロイ溝41の奥の壁部43に当接する当接部63と、基部62から延びる平面視略Z字状の弾性部64とを具備する。この弾性部64の先端には、当接部63の先端に形成された被掛止部65に掛止される掛止部66が形成されている。また、弾性部64の先端寄りには連結軸7が挿通される軸孔67が設けられている。   The temple 5 is a long member formed of a synthetic resin such as acetate, for example, like the front frame 3, and the projecting piece 51 provided at the end on the connection side is externally fitted to the connection shaft 7 and is fixed to the leaf spring 6. Can be pivotally attached to each other. The material of the temple 5 is not limited to synthetic resin, and may be formed of a metal such as titanium. As shown in FIG. 3, the leaf spring 6 extends from the base portion 62 provided with the locking hole 61 and contacts the wall portion 43 at the back of the armor groove 41 when the leaf spring 6 is housed in the armor groove 41. The contact part 63 which contacts, and the elastic part 64 of planar view substantially Z shape extended from the base 62 are comprised. At the distal end of the elastic portion 64, a latching portion 66 that is latched by the latched portion 65 formed at the distal end of the contact portion 63 is formed. A shaft hole 67 through which the connecting shaft 7 is inserted is provided near the tip of the elastic portion 64.

この板バネ6を製作するときには、図3(A)に示すように、被掛止部65に掛止部66は掛止されていない状態で製作される。このときには板バネ6は殆ど弾性変形していない。そして、この板バネ6を用いてヨロイ4にテンプル5を連結させるときには、図3(B)に示すように、被掛止部65に掛止部66を掛止させる。これにより弾性部64は、当接部63方向にやや弾性変形された状態を維持される。開いた状態のテンプル5を更に外側方向に押し広げたときには、図3(C)に示すように、弾性部64が弾性変形して当接部63との間の間隙及び弾性部64内の間隙が狭まって、テンプル5を軸支する連結軸7の位置が外側方向に移動する。なおこのとき、当接部63は殆ど弾性変形していない。   When this leaf spring 6 is manufactured, as shown in FIG. 3A, the leaf spring 6 is manufactured in a state where the hook portion 66 is not hooked to the hook portion 65. At this time, the leaf spring 6 is hardly elastically deformed. When the temple 5 is connected to the armor 4 using the leaf spring 6, the latching portion 66 is latched to the latched portion 65 as shown in FIG. As a result, the elastic portion 64 is maintained in a state where it is slightly elastically deformed toward the contact portion 63. When the temple 5 in the opened state is further spread outward, the elastic part 64 is elastically deformed and the gap between the contact part 63 and the gap in the elastic part 64 as shown in FIG. Narrows and the position of the connecting shaft 7 that pivotally supports the temple 5 moves outward. At this time, the contact portion 63 is hardly elastically deformed.

このように掛止部66に被掛止部65を掛止させることで、弾性部64は掛止部66の移動にともなって外側方向に弾性変形した状態を維持する。そして、弾性部64の復元力により掛止部66は内側方向に力がかかった状態で被掛止部65に掛止される。このように掛止部66は被掛止部65に掛止されることで、内側方向に力が加わっても内側方向に移動することなくその状態を維持する。また、常に内側方向に力が加わっているので、外側方向に所定未満の小さな力が加わった場合にも外側方向に移動することなくその状態を維持する。したがって、少しの力が加わっただけでは板バネ6は弾性変形せずそのままの状態を維持するので、テンプル5が不必要に揺れることを防ぐことを抑制できる。   As described above, the hooked portion 66 is hooked on the hooking portion 66, so that the elastic portion 64 is maintained in a state of being elastically deformed outward as the hooking portion 66 moves. And the latching | locking part 66 is latched by the to-be-latched part 65 in the state in which the force was applied to the inner direction with the restoring force of the elastic part 64. FIG. Thus, the latching part 66 is latched by the latched part 65, and even if force is applied to the inner side, the state is maintained without moving inward. Further, since the force is always applied in the inner direction, even when a small force less than a predetermined value is applied in the outer direction, the state is maintained without moving in the outer direction. Therefore, since the leaf spring 6 is not elastically deformed and is maintained as it is by applying a little force, it is possible to prevent the temple 5 from being unnecessarily shaken.

テンプル5に対して外側方向の所定以上の大きな力が加わった場合には、弾性部64が弾性変形して掛止部66及び連結軸7が外側方向に移動する。したがって、テンプル5を外側方向に押し広げることができる。このとき当接部63は殆ど弾性変形しないので、ヨロイ溝41の奥の壁部43に当接した状態を維持することとなる。このように当接部63がヨロイ溝41の奥の壁部43に当接した状態を維持することで、板バネ6がヨロイ4に対してがたつくことを抑制することができる。   When a large force greater than a predetermined value is applied to the temple 5 in the outward direction, the elastic portion 64 is elastically deformed and the latching portion 66 and the connecting shaft 7 move in the outward direction. Therefore, the temple 5 can be spread outward. At this time, since the contact portion 63 hardly undergoes elastic deformation, the state in which the contact portion 63 is in contact with the wall portion 43 at the back of the end groove 41 is maintained. Thus, by maintaining the state in which the contact portion 63 is in contact with the inner wall portion 43 of the armor groove 41, it is possible to suppress the leaf spring 6 from rattling against the armor 4.

次に、ヨロイ4に板バネ6を固定する構造について図4から図6を参照しつつ説明する。なお、図5は、板バネ6をヨロイ4に固定する構造を説明する斜視図であるが、説明の都合上ヨロイ4の構成を省略している。ヨロイ4に板バネ6を固定するときには、ボルト81と、ボルト81が挿通されるワッシャー82と、ボルト81に螺合される袋ナット83と、を用いる。ボルト81は、ヨロイ4に下側から掘られたバネ止め孔42に挿入できる大きさであり、ワッシャー82に嵌挿した状態で袋ナット83と螺合できる長さのものである。また、ワッシャー82はバネ止め孔42の内周面の径よりやや小さな外径の円筒状の部材であって、一端側がテーパー状に尖っている。袋ナット83は、ワッシャー82とほぼ同じ外径であって、内周面にボルト81と螺合する雌ネジを有し、開口端がテーパー状に尖って形成されている。   Next, a structure for fixing the leaf spring 6 to the alloy 4 will be described with reference to FIGS. FIG. 5 is a perspective view illustrating a structure for fixing the leaf spring 6 to the armor 4, but the structure of the armor 4 is omitted for convenience of explanation. When fixing the leaf spring 6 to the armor 4, a bolt 81, a washer 82 through which the bolt 81 is inserted, and a cap nut 83 that is screwed into the bolt 81 are used. The bolt 81 is of a size that can be inserted into the spring retaining hole 42 dug into the armor 4 from below, and has a length that can be screwed into the cap nut 83 in a state of being fitted into the washer 82. Further, the washer 82 is a cylindrical member having an outer diameter slightly smaller than the diameter of the inner peripheral surface of the spring retaining hole 42, and one end side is pointed in a tapered shape. The cap nut 83 has substantially the same outer diameter as the washer 82, has an internal thread that engages with the bolt 81 on the inner peripheral surface, and has an open end that is tapered.

以上のような構成を用いてヨロイ4に板バネ6を固定するときには、図6によく表れているように、まず、バネ止め孔42に袋ナット83を袋ナット83の開口していない側の端部から挿入する。そして、袋ナット83が挿入された状態で、ヨロイ4に形成された2つのヨロイ溝41にそれぞれ板バネ6を挿入し、板バネ6の当接部63をヨロイ溝41の奥の壁部43に当接させる。ここで、板バネ6の係止孔61は当接部63をヨロイ溝41の奥の壁部43に当接させたときに、その軸芯がヨロイ4のバネ止め孔42の軸芯よりもやや眼鏡内側方向にずれて位置するように形成されている。すなわち、係止孔61の軸芯はバネ止め孔42の軸芯よりも壁部43と反対方向にずれるように形成されている。次に、ワッシャー82を尖った端部からバネ止め孔42に挿入する。そしてボルト81をバネ止め孔42に挿入し、ワッシャー82及び2つの板バネ6の係止孔61を嵌挿させつつ袋ナット83に螺合させる。   When the leaf spring 6 is fixed to the armor 4 using the above-described configuration, as shown in FIG. 6, first, the cap nut 83 is inserted into the spring retaining hole 42 on the side where the cap nut 83 is not open. Insert from the end. Then, in the state where the cap nut 83 is inserted, the leaf spring 6 is inserted into each of the two armor grooves 41 formed in the armor 4, and the contact portion 63 of the leaf spring 6 is connected to the wall part 43 at the back of the armor groove 41. Abut. Here, the locking hole 61 of the leaf spring 6 has an axial center that is greater than the axial center of the spring retaining hole 42 of the armor 4 when the abutting part 63 is brought into contact with the inner wall 43 of the armor groove 41. It is formed so as to be slightly shifted inward of the glasses. That is, the axial center of the locking hole 61 is formed so as to be displaced in the direction opposite to the wall 43 from the axial center of the spring retaining hole 42. Next, the washer 82 is inserted into the spring retaining hole 42 from the sharp end. Then, the bolt 81 is inserted into the spring retaining hole 42 and screwed into the cap nut 83 while the washer 82 and the locking hole 61 of the two leaf springs 6 are inserted.

このようにボルト81を袋ナット83に螺合させたときに、袋ナット83及びワッシャー82の尖った端部は互いに対向し、ボルト81を更に締めると袋ナット83及びワッシャー82は互いに近づく方向に移動する。したがって、袋ナット83に螺合したボルト81を更に締めると、袋ナット83とワッシャー82との間に挟まれている2枚の板バネ6のそれぞれの係止孔61に袋ナット83又はワッシャー82が当接する。係止孔61はバネ止め孔42に対して内側方向にずれているので、袋ナット83及びワッシャー82のテーパー状に尖った端部の眼鏡外方向側がバネ止め孔42に当接される。そして、ボルト81を更に締めようとすると、袋ナット83及びワッシャー82の双方が互いに接近する方向に力が加わり、それぞれの係止孔61に当接する部分を介して板バネ6に眼鏡外方向側の力が加わる。したがって、板バネ6の当接部63はヨロイ4のヨロイ溝41の奥の壁部43に押し付けられるので、板バネ6をがたつくことなくヨロイ4に固定することができる。   When the bolt 81 is screwed to the cap nut 83 in this way, the sharp ends of the cap nut 83 and the washer 82 are opposed to each other, and when the bolt 81 is further tightened, the cap nut 83 and the washer 82 approach each other. Moving. Therefore, when the bolt 81 screwed to the cap nut 83 is further tightened, the cap nut 83 or the washer 82 is inserted into the respective locking holes 61 of the two leaf springs 6 sandwiched between the cap nut 83 and the washer 82. Abut. Since the locking hole 61 is displaced inwardly with respect to the spring retaining hole 42, the eyeglass outer direction side of the tapered end portions of the cap nut 83 and the washer 82 is brought into contact with the spring retaining hole 42. When the bolt 81 is further tightened, a force is applied in a direction in which both the cap nut 83 and the washer 82 approach each other. The power of. Accordingly, the abutting portion 63 of the leaf spring 6 is pressed against the wall 43 at the back of the armor groove 41 of the armor 4 so that the leaf spring 6 can be fixed to the armor 4 without rattling.

次に、以上のような眼鏡を装着するときの眼鏡のテンプル連結構造の動きについて、図7から図9を参照しつつ説明する。板バネ6の弾性部64に形成された軸孔67とテンプル5の突片51に設けられた図示しない回動孔とには、互いに整合した状態で連結軸7が挿入されており、テンプル5は板バネ6に対して回動可能となっている。ここで、テンプル5は開いた状態及び閉じた状態のときに板バネ6と当接するように形成されており、テンプル5の板バネ6に対する回動範囲を例えば90度に規制している。   Next, the movement of the temple connecting structure of the glasses when wearing the above glasses will be described with reference to FIGS. A connecting shaft 7 is inserted into a shaft hole 67 formed in the elastic portion 64 of the leaf spring 6 and a rotation hole (not shown) provided in the protruding piece 51 of the temple 5 so as to be aligned with each other. Is rotatable with respect to the leaf spring 6. Here, the temple 5 is formed so as to come into contact with the leaf spring 6 in the open state and the closed state, and the rotation range of the temple 5 with respect to the leaf spring 6 is restricted to 90 degrees, for example.

まず、両側の閉じられた状態のテンプル5をそれぞれ回動範囲で開く。そして、更に板バネ6を弾性変形させてテンプル5を外側に押し広げる。このとき板バネ6の当接部63はヨロイ4のヨロイ溝41の奥の壁部43に当接しているので、当接部63は弾性変形せずに壁部43に押し付けられる。そして、弾性部64が弾性変形してテンプル5と連結している連結軸7を外方向に移動させることで、テンプル5を外側方向に押し広げる。弾性部64が外側方向に弾性変形すると弾性部64の先端に形成された掛止部66がヨロイ4と当接するので、弾性部64は掛止部66が被掛止部65に掛止された状態からヨロイ4と当接する状態の範囲で弾性変形する。このように弾性部64の変形範囲が限られているので、板バネ6が塑性変形することを防ぐことができる。そして、テンプル5を押し広げた状態で眼鏡をかけると、板バネ6の復元力により眼鏡装着者の顔側面から頭部にテンプル5がフィットする。   First, the temples 5 in the closed state on both sides are each opened in the rotation range. Then, the leaf spring 6 is further elastically deformed to push the temple 5 outward. At this time, the contact portion 63 of the leaf spring 6 is in contact with the wall portion 43 at the back of the armature groove 41 of the armor 4, so that the contact portion 63 is pressed against the wall portion 43 without elastic deformation. Then, the elastic portion 64 is elastically deformed and the connecting shaft 7 connected to the temple 5 is moved outward, thereby pushing the temple 5 outward. When the elastic portion 64 is elastically deformed outward, the latching portion 66 formed at the tip of the elastic portion 64 contacts the armor 4, so that the latching portion 66 of the elastic portion 64 is latched by the latched portion 65. It is elastically deformed in a range from the state to the state in contact with the armor 4. As described above, since the deformation range of the elastic portion 64 is limited, the plate spring 6 can be prevented from being plastically deformed. When the eyeglasses are put on with the temples 5 being spread out, the temples 5 are fitted from the side face of the eyeglass wearer to the head by the restoring force of the leaf springs 6.

本発明の実施の形態は上述の形態に限ることなく、本発明の思想の範囲を逸脱しない範囲で適宜変更することができる。   The embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

本実施形態においては、ヨロイ4のヨロイ溝41が2つ形成されておりそれぞれのヨロイ溝41に板バネ6を収納する構成であった。このように2つの板バネを用いてヨロイ4とテンプル5を連結することで、テンプルが開閉方向以外に揺れることを抑制する顕著な効果を有するものであるが、本発明の実施形態はこれに限定されるものではなく、例えばヨロイ4に2以上のヨロイ溝41を形成するスペースがない場合には、図10に示すように、ヨロイ4にヨロイ溝41を1つのみ形成し板バネ6を収納する構成とすることもできる。この場合には、ボルト81を端部がテーパー状に尖ったワッシャー82に挿通させなくても、袋ナット83のテーパー状に尖った端部で、板バネ6の係止孔61を固定することができる。なお、このときボルトは、平たい円筒状の座金84に挿通しておくことで、ナットに容易に締着することができる。   In the present embodiment, two armor grooves 41 of the armor 4 are formed, and the leaf spring 6 is accommodated in each of the armor grooves 41. Thus, by connecting the armor 4 and the temple 5 by using two leaf springs, it has a remarkable effect of suppressing the temple from swinging in directions other than the opening / closing direction. For example, when there is no space for forming two or more alloy grooves 41 in the alloy 4, as shown in FIG. 10, only one alloy groove 41 is formed in the alloy 4 and the leaf spring 6 is formed. It can also be set as the structure accommodated. In this case, the locking hole 61 of the leaf spring 6 is fixed by the tapered end of the cap nut 83 without inserting the bolt 81 into the washer 82 having the tapered end. Can do. At this time, the bolt can be easily fastened to the nut by being inserted through the flat cylindrical washer 84.

また、本実施形態においてはヨロイ溝41はヨロイ4の内側を開口し、ヨロイ4の外側に壁部43が形成される構成であるが、本発明の実施形態はこれに限定されるものではなく、例えばヨロイ溝41がヨロイ4の外側を開口し、ヨロイ4の内側には壁部43が形成される構成であってもよい。この場合、板バネ6が壁部43に当接したとき、板バネ6の係止孔61はバネ止め孔42に対して外側にずれるように構成すればよい。   Further, in the present embodiment, the armor groove 41 is configured to open the inner side of the armor 4 and the wall part 43 is formed on the outer side of the armor 4, but the embodiment of the present invention is not limited to this. For example, the configuration may be such that the armor groove 41 opens the outer side of the armor 4 and the wall 43 is formed inside the armor 4. In this case, when the leaf spring 6 comes into contact with the wall portion 43, the locking hole 61 of the leaf spring 6 may be configured to be shifted outward with respect to the spring retaining hole 42.

本発明は、眼鏡のヨロイ4とテンプル5とを連結する構造及び眼鏡フレーム2に好適に適用することができる。   The present invention can be suitably applied to a structure for connecting the eyeglass armor 4 and the temple 5 to the eyeglass frame 2.
