【考案の詳細な説明】
本考案は眼鏡フレーム、サングラスフレームに関し、レ
ンズに歪を与えないためのレンズ保持構造を提供するも
のである。[Detailed Description of the Invention] The present invention relates to eyeglass frames and sunglass frames, and provides a lens holding structure for preventing distortion from being applied to the lenses.
眼鏡あるいはサングラスにおいてレンズに歪みが存在す
る場合には使用者の眼に極めて有害であり、視力を劣化
させる原因になる。When lenses of glasses or sunglasses are distorted, it is extremely harmful to the user's eyes and causes deterioration of visual acuity.
このために本考案はレンズ保持に係わる新たな構造を提
供することによりレンズに歪を与えず、従って使用者の
眼に対し何ら害を与えず本来の眼鏡の役割を得るもので
ある。For this reason, the present invention provides a new structure for holding lenses so that the lenses do not become distorted, thereby causing no harm to the user's eyes and achieving the original role of eyeglasses.
本考案について一実施例を図に基き説明する。An embodiment of the present invention will be explained based on the drawings.
第１図において、１はフレーム（図示せず）のツムに相
当し、２はレンズ、３はレンズ保持部材である。In FIG. 1, 1 corresponds to a knob of a frame (not shown), 2 is a lens, and 3 is a lens holding member.
リム１の内面には凹部が配設され該凹部にレンズ保持部
材３の凸部４が嵌合固着している。A concave portion is provided on the inner surface of the rim 1, and a convex portion 4 of the lens holding member 3 is fitted and fixed in the concave portion.
またレンズ２の端面側にも凹部が配設されレンズ保持部
材３の凸部５が嵌合しレンズを保持している。Further, a concave portion is provided on the end surface side of the lens 2, and a convex portion 5 of the lens holding member 3 is fitted into the concave portion to hold the lens.
さらにレンズ保持部材３はリム１の内面とレンズ２の端
面の間にツバ部６を有しており、ツムにレンズが取付け
られた状態で該ツバ部６においてレンズ端面を受けた状
態でレンズ２を支えている。Further, the lens holding member 3 has a collar portion 6 between the inner surface of the rim 1 and the end surface of the lens 2, and when the lens is attached to the tab, the lens end surface is received at the collar portion 6. supporting.
レンズ保持部材３は軟かい弾力性に富んだプラスチック
、例えばポリアミド樹脂、ポリプロピレン樹脂あるいは
ゴムからなり、保持されたレンズは直接金属製のリムに
接触せずに上記のプラスチックあるいはゴムに接触して
いるためリムへの取付による圧力に対してもレンズ保持
部材が緩衝材となって作用レンズに歪みを与えることを
防止している。The lens holding member 3 is made of soft and highly elastic plastic, such as polyamide resin, polypropylene resin, or rubber, and the held lens does not come into direct contact with the metal rim, but contacts the plastic or rubber mentioned above. Therefore, the lens holding member acts as a buffer material against the pressure caused by attachment to the rim, and prevents distortion from being applied to the working lens.
より完全に歪みを防止するためにはレンズ保持部材の材
質選択とツバ部の厚さによって解決をはかれば充分可能
である。In order to more completely prevent distortion, it is possible to solve the problem by selecting the material of the lens holding member and the thickness of the flange.
例としてはレンズ保持部材にナイロン樹脂を用いツバ部
６の厚さを０．２〜０．４ｍｍとすれば眼鏡使用者に対
し全く安全な水準の歪の範囲を得ることができる。For example, if the lens holding member is made of nylon resin and the thickness of the collar 6 is set to 0.2 to 0.4 mm, it is possible to obtain a distortion range that is completely safe for eyeglass users.
また図示した形状のレンズ保持部材の製造も延伸加工技
術の水準より極めて容易に安価に得ることができるもの
であり実用上も問題がない。Furthermore, the lens holding member having the shape shown in the drawings can be manufactured very easily and inexpensively compared to the level of stretching technology, and there is no problem in practical use.
次に別の実施例について述べる。Next, another example will be described.
近年フレームの軽量化および視野の増大等の要求が強く
なり、フレームの形態としてリムレスフレームとよばれ
るフレームばある。In recent years, there has been a strong demand for lighter frames and increased field of view, and a frame called a rimless frame is now available.
このリムレスフレームの１つとしてレンズ周縁の一部に
リムを用い、他の部分は細い線材、例えばプラスチック
の線あるいは金属線を用いレンズを取付ける構造のフレ
ームがある。One type of rimless frame has a structure in which a rim is used for a part of the lens periphery, and the lens is attached to the other part using a thin wire, such as a plastic wire or a metal wire.
第２図において１′はリム、２′はレンズ、３′はレン
ズ保持部材であり、７はレンズ吊り線である。In FIG. 2, 1' is a rim, 2' is a lens, 3' is a lens holding member, and 7 is a lens hanging line.
従ってリムとレンズとレンズ保持部材の関係については
前記実施例と全く同一である。Therefore, the relationship between the rim, lens, and lens holding member is exactly the same as in the previous embodiment.
