Description

本考案は、眼鏡フレームのテンプルが折り畳みできるように用いられる丁番部の構造に関する。 The present invention relates to a structure of a hinge portion used so that a temple of a spectacle frame can be folded.

一般の眼鏡フレームのテンプルは小さな丁番を介して折り畳みとその開閉を可能に連結されている。しかしテンプル開閉を繰り返すことにより小さな丁番はその軸ネジが緩んだり、摺動面が磨耗したりしてガタ付き、その結果テンプル開閉の安定性が損なわれ、時には開閉を維持できない状態になることも多い。その問題を解決するために特許文献１で示すような構造をもった商品も知られている。 A temple of a general spectacle frame is connected through a small hinge so that it can be folded and opened and closed. However, by repeatedly opening and closing the temple, the small hinge will loosen its shaft screw and the sliding surface will wear, resulting in the stability of the temple opening and closing, and sometimes the opening and closing cannot be maintained. There are also many. In order to solve the problem, a product having a structure as shown in Patent Document 1 is also known.

上記のように長期的に眼鏡フレームのテンプル開閉の安定性を損なわない構造商品には、開閉時の心地よいトルク感を追及した商品は少ない。この心地よいトルク感は消費者の個々の感覚であるため調整ができることが求められるが、丁番ネジなどが緩まない構造を追及していることにより調整ができる機能には殆んどなっていない。また、摺動面の滑らかさと万が一の磨耗部品の交換の容易性を備えた構造であることも必要である。 As described above, there are few products that pursue a comfortable torque feeling at the time of opening and closing in the structure products that do not impair the stability of the opening and closing of the temples of the eyeglass frame over the long term. Although this comfortable torque feeling is an individual sense of the consumer, it is required to be adjustable, but there are few functions that can be adjusted by pursuing a structure in which the hinge screw or the like is not loosened. It is also necessary to have a structure with smooth sliding surfaces and easy replacement of worn parts.

本考案は、眼鏡フレームのテンプル開閉に求められる上記機能を全て備え、かつ開閉時の滑らかな心地よいトルク感の他に心地よいクリック感の開閉への変更可能な機能を備えた丁番構造を提供するものである。 The present invention provides a hinge structure having all the functions required for opening and closing a temple of a spectacle frame, and a function that can be changed to open and close a comfortable click feeling in addition to a smooth and comfortable torque feeling at the time of opening and closing. Is.

本考案は、眼鏡フレームのフロントフレームとテンプルを繋ぐヨロイに設けられた円形の貫通孔に、テンプルに設けられた円柱形凸シリンダーの切り込み部に回転摺動面になる樹脂部品を確り固定する様に組み込んだ形で差込み、ヨロイの側面から貫通孔までに施した貫通ネジ穴に押さえ部品とスプリングを順次進入し、止めネジで締め付けることを特徴とする。 In the present invention, a resin part that becomes a rotational sliding surface is securely fixed to a circular through hole provided in an armor connecting a front frame of a spectacle frame and a temple to a cut portion of a cylindrical convex cylinder provided in the temple. It is characterized in that it is inserted in a shape that is inserted into the armor, and the holding part and the spring are sequentially inserted into the through screw holes formed from the side surface of the armor to the through hole, and tightened with a set screw.

上述したように本考案は、ヨロイとテンプルの回転摺動面をスプリングを解してネジ締めする構造のため、回転摺動面に常に一定に近い圧力を掛けることが可能となり安定したトルクの開閉が実現する。 As described above, the present invention has a structure in which the rotational sliding surface of the armor and temple is screwed by releasing the spring, so that it is possible to always apply a constant pressure to the rotational sliding surface, and stable torque opening and closing. Is realized.

同時に止めネジによる締め付け具合で開閉のトルク調整も可能である。 At the same time, the opening and closing torque can be adjusted by tightening with a set screw.

また、スプリングを解してのネジ締めにより止めネジには常にスプリングの圧力がかかっているためネジ緩みが起こり難い。 Further, since the spring pressure is always applied to the set screw by tightening the screw with the spring unscrewed, it is difficult for the screw to loosen.

ヨロイ側の回転摺動面に金属製の押さえ部品と滑り的に相性の良いポリアセタール樹脂材を使用することで、滑らかで心地良い回転開閉を実現する。 By using a polyacetal resin material that is slidably compatible with metal holding parts on the rotating sliding surface on the side of the armor, a smooth and comfortable rotational opening and closing is realized.

ヨロイ側の回転摺動面がはめ込み式部品構造のため、万が一に回転摺動面の部品が磨耗した時には部品交換が可能である。 Since the rotary sliding surface on the side of the armor is fitted, the parts can be replaced when the components on the rotary sliding surface wear out.

また、樹脂部品の回転摺動面に一定間隔に凹溝などを施した別部品と交換することで、開閉時に心地よいクリック感のある回転開閉に変更が可能である。 In addition, by replacing with a rotating part of the resin part that is provided with a concave groove or the like at regular intervals, it can be changed to a rotational opening and closing with a comfortable click feeling when opening and closing.

The resin part 7 is inserted so as to be securely fixed, and the holding part 9 and the spring 10 are sequentially entered into the through screw hole 8 formed from one surface of the armor 3 to the through hole 4 to form a rotational sliding surface. It is possible to fold and open and close the temple 2 without pulling the temple 2 up and down by unscrewing the spring 10 at the tip of the R shape of the resin part 7 and tightening it with the set screw 11. Can be linked.
