Abstract

PROBLEM TO BE SOLVED: To enable a glare-preventive shading lens to be firmly fixed on a correction lens so as not to be detached in outdoor activities or sports as well in which a highly-curved frame with highly-curved lenses attached is frequently used.SOLUTION: Overlap lens spectacles include: a main lens (10) processed such that a step-like protrusion (16) is provided on the peripheral edge in the outer surface side of a lens over the whole circumference thereof, and the peripheral edge in the inner surface side of the lens is formed to be a stepped-down shape (19) over the whole circumference thereof; and a sub-lens (30) having a rear face with the same curvature as the outer surface of the main lens and with a congruent shape so as to be brought into close contact with the whole outer surface of the main lens. With both of them overlapped, the step-like protrusion part of the main lens and the peripheral part of the sub-lens as overlapped each other are, in the state of being both brought into close contact, inserted and fit into a recessed step groove (42) provided on the inner side of a rim (40) of the spectacles, and both the lenses are firmly fixed on a spectacle frame by closing the rim.

Description

本発明は、二枚以上のレンズを重ねた重ねレンズ眼鏡に関する。好ましくは、アウトドアー活動、スポーツ等で使用される中又は高カーブフレームに対応する中・高カーブレンズ（矯正レンズ）と遮光レンズとの重ねレンズ眼鏡に関し、特に好ましくは高（ハイ）カーブフレーム及びそれに対応する高（ハイ）カーブレンズと高（ハイ）カーブ遮光レンズとの重ねレンズ眼鏡に関する。The present invention relates to a stacked lens spectacle in which two or more lenses are stacked. Preferably, the present invention relates to a high-high curve frame and a high-high curve frame, particularly for a middle / high curve lens (correction lens) and a light-shielding lens corresponding to a medium or high curve frame used in outdoor activities or sports. The present invention relates to a superposed lens spectacle of a corresponding high (high) curve lens and a high (high) curve light-shielding lens.

従来、主レンズである矯正レンズを掛けた際の眩しさ除けや、日除けの為に、主レンズ前方に遮光レンズを設ける事は行われてきた。その様な技術としては、例えば、特開平０７−１２８６２０の様にマグネットで眼鏡フレームにサングラス等の補助レンズフレームを付けた技術が提案されている。Conventionally, a shading lens has been provided in front of the main lens in order to avoid glare when the correction lens, which is the main lens, is applied, and to avoid the sun. As such a technique, for example, a technique in which an auxiliary lens frame such as sunglasses is attached to a spectacle frame with a magnet has been proposed as disclosed in JP-A-07-128620.

特開平０７−１２８６２０JP 07-128620 A

しかしながら、図１に示された上記特開平０７−１２８６２０の様にサングラスレンズフレームをマグネット等で眼鏡フレームに係止する技術は確かに取り外しには便利であるが、上記した様なアウトドアー活動、スポーツで動き回る際には外れ易くフロント部分が重く、前屈みになるだけで眼鏡がずれて来る事になる。又、従来の一般的な眼鏡に於いても、通常はレンズを保持するのに図２の様にリム１でレンズ縁の薬研２をリムの薬研溝３に嵌め込んで留めているのが殆どである。その為、図３の様なアウトドアー活動向けやスポーツで多く使用されるカーブの大きい高（ハイ）カーブのフレーム１１に嵌め込むのに適している図４の様なハイカーブレンズ２１の使用に於いては、主レンズを主フレーム薬研溝に薬研をレンズ全周にわたり嵌め込むのは困難である。そして、嵌まった場合でも非常に外れ易く、ましてや、補助フレームや副レンズを付けることは困難であった。それに加えて最近は度付きのハイカーブレンズが多くなってきており、その様な眼鏡に遮光具を付けるのは更に困難であった。However, the technique of locking the sunglasses lens frame to the spectacle frame with a magnet or the like as in the above-mentioned Japanese Patent Application Laid-Open No. 07-128620 shown in FIG. 1 is certainly convenient for removal, but the outdoor activities and sports as described above. When moving around, the front part is easy to come off and the front part is heavy, and the glasses will be displaced just by bending forward. Further, even in conventional general spectacles, in general, in order to hold the lens, the lens edge 2 on the lens edge is usually fitted into the edge 3 on the rim 1 as shown in FIG. It is. For this reason, in the use of the high curve lens 21 as shown in FIG. 4 which is suitable for fitting into a high curve frame 11 having a large curve which is often used for outdoor activities and sports as shown in FIG. It is difficult to fit Yakuken into the main frame Yakuken groove all around the lens. And even if it is fitted, it is very easy to come off, and it is difficult to attach an auxiliary frame or a sub lens. In addition, the number of high-curve lenses with a degree has increased recently, and it has been more difficult to attach a shading device to such glasses.

上記課題を解決する為に、本発明に於いては、レンズ外側表面の外周縁が全周にわたり段状突起が設けられ、そして、レンズ内側表面の外周縁が全周にわたり段落ちとなるように加工された主レンズと、該主レンズの外側表面全体に密着する様に主レンズ外側表面と同じ曲率で合同形の裏面を有する副レンズとを、重ね合わせて、眼鏡のリムの内側に設けられた凹型の段溝に、重ね合わされた前記主レンズ段状突起部と前記副レンズ縁部との両方が密着した状態で挿入嵌合され、そしてリムを閉じる事により両レンズが眼鏡フレームにしっかり固定された事を特徴とする重ねレンズ眼鏡により解決手段の提供を図った。In order to solve the above problems, in the present invention, the outer peripheral edge of the lens outer surface is provided with stepped protrusions over the entire periphery, and the outer peripheral edge of the lens inner surface is stepped down over the entire periphery. And a secondary lens having a congruent back surface with the same curvature as the outer surface of the main lens so as to be in close contact with the entire outer surface of the main lens, and provided inside the rim of the glasses. Inserted and fitted into the concave step groove with both the primary lens step projection and the secondary lens edge in close contact with each other, and by closing the rim, both lenses are firmly fixed to the spectacle frame. The solution was provided by the overlapping lens glasses characterized by

上記手段を採る事により、先ず高（ハイ）カーブフレームに高（ハイ）カーブの矯正用レンズである高（ハイ）カーブの主レンズがしっかり嵌り、更に、高（ハイ）カーブの遮光レンズである高（ハイ）カーブの副レンズが主レンズに密着し、眼鏡の凹型のリムに両方がしっかり保持される事によりガタツキガ無く、余分な留め金具の必要が無く軽く、アウトドアー活動、スポーツを楽しむ事が可能となった。By adopting the above means, first, a high (high) curve main lens, which is a high (high) curve correction lens, is firmly fitted in a high (high) curve frame, and further, a high (high) curve light-shielding lens. The high-curve sub-lens is in close contact with the main lens, and both are firmly held by the concave rim of the glasses. It has become possible.

In this embodiment, a description will be given based on an embodiment manufactured using a high (high) curve frame using a high (high) curve (6-8 curve) lens. Of course, in the present invention, the present invention can be carried out even with a medium curve lens. As described above, FIG. 1, FIG. 2, FIG. 3, and FIG. In FIG. 5, the outer peripheral edge 14 of the lens outer surface 12 of the main lens 10 extends over the entire circumference, and stepped protrusions 16 are provided in a direction diffusing in parallel from the lens center to the outer surface, and the lens inner surface 17 of the main lens 10. The main lens 10 processed so that the outer peripheral edge 18 thereof is stepped 19 over the entire periphery, and the outer surface of the main lens so as to be in close contact with the entire outer surface of the main lens (including stepped protrusions in this case) 6 is a state before superimposing with the secondary lens 30 having the same curvature and the back surface 32 of the congruent shape, and FIG. 6 shows the rim of the high curve frame by superimposing the main lens 10 and the secondary lens 30. It is a partial cross-sectional plan view of the present invention in a state where it is inserted and fitted, and even when it is largely curved to secure a field of view, it stably holds the overlapping lens and is easy to hang lightly and hang on a cap Also when placing Do not care do not become magic.

図７は本発明の重ねレンズ眼鏡の背面図であり、この実施例の場合はリムを分離又は結合する手段はブリッジ部に設けてあるが、これは智又はヨロイ部分であっても勿論構わない。FIG. 7 is a rear view of the superposed lens glasses according to the present invention. In this embodiment, the means for separating or connecting the rim is provided in the bridge portion, but it may of course be the wisdom or armor portion. .

図８は図７のＡ−Ａ断面拡大図であり、リム４０の凹型の段溝４２に高（ハイ）カーブの主レンズ（度付き、矯正）１０の外周縁の１４の段状突起１６部と、該主レンズの外側表面全体に密着する様に主レンズ外側表面と同じ曲率で合同形の裏面３２を有する高（ハイ）カーブの副レンズ（遮光）３０、例えば、サングラスレンズ、偏光レンズ、調光レンズ等、の外周縁３４の両方をしっかり嵌合し保持する。最近のサングラスレンズや偏光レンズ等は薄く性能の良い製品があるので、こちらの副レンズの縁は段状突起や段落ち加工をしなくても良い。FIG. 8 is an enlarged cross-sectional view taken along the line AA of FIG. 7. A high-curve sub-lens (light-shielding) 30 having a congruent back surface 32 with the same curvature as the main lens outer surface so as to be in close contact with the entire outer surface of the main lens, for example, a sunglasses lens, a polarizing lens, Both the outer peripheral edges 34 of the light control lens and the like are firmly fitted and held. Since recent sunglasses lenses and polarizing lenses are thin and have good performance, the edge of this secondary lens does not have to be stepped or stepped.
