Definitions
- the present invention relates to a bifocal frame that can be used for different types of lenses.
- near-distance spectacles have an upper part of one lens for hyperopia and a lower part for near-sightedness.
- the spectacle wearer changes the direction of the eyeball and changes the viewing angle.
- the current situation is that when looking at things, they are looking at them using their lower eyes.
- FIG. 16A since the line of sight looks at the object from the horizontal position downward, it is natural to look straight at the object (view with a line of sight where the center of the lens matches the eye height).
- the line of sight when looking at a nearby object in particular, tends to be unreasonable due to an unnatural way of viewing and unnatural usage, and easily induces eye fatigue.
- spectacles that reverse the spectacles themselves
- spectacles that bring the height of the spectacles close to the eye position by adjusting the height of the nose pad position.
- a proposal for reversing the spectacles itself is, for example, Japanese Patent Laid-Open No. 7-199126, which reverses the vine so that the spectacles can be reversed and moves the earpiece up and down.
- the nose pad is moved up and down so that the eyes are positioned near the center of the far-medium vision part or the near vision part.
- the eyeglasses that invert the eyeglasses themselves have a vine attachment at the center height outside the eyeglass frame, so even if the eyeglasses are inverted, the line of sight comes to the boundary between the upper and lower lenses, making it difficult to see.
- the height of the nose pad must be adjusted. It is necessary to adjust the vertical height by moving the nose pad up and down after the glasses are turned upside down, and it is cumbersome and the fine adjustment to move the nose pad up and down is quite accurate. It is difficult.
- the line of sight at this time is as shown in FIG. 16C, and the eye height is deviated, and the entire lens is tilted as shown in the figure, so that eye fatigue cannot be eliminated. It was.
- Japanese Patent Application Laid-Open No. 7-159733 are simply integrated in the shape of the upper and lower ear pads, so that it looks bad and uncomfortable. It was lacking.

Abstract
Description
本発明の別の目的は、レンズの上下を反転して異種類のレンズなどを簡単に使い分け出来ると共に、レンズなどの中心と目の高さを合致させて眼精疲労が軽減され、且つ、レンズなどの交換が出来る遠近両用眼鏡状のフレームを提供することにある。
又、吊下軸に多角形状の柱を或いは一対の軸を用い、一対の軸を用いる時には、各軸の下端に抜け止め部を設ける。またスライド手段として、吊下軸に挿入してスライドするスライド軸受と、該スライド軸受を吊下軸の所定の位置に保持とする保持部材と、吊下軸の端部に設けた抜け防止具と、を備えたものとしても良い。更に保持機構として、1)スライド軸受に取付けた係止片と、該係止片を吊下軸に押圧するためのバネ材とから構成する係止方式のもの、2)吊下軸に挟持可能にするための弾性を有する挟持本体と、該挟持本体の端部を開くためのツマミ部と、を備えたダブルクリップ状のもの及びその変形したもの、3)吊下軸の上下端部に固着する磁石と、スライド軸受の上下端部に取付けた鉄板とから構成する着磁方式のもの、4)スライド軸受の表面に2つ設けた掛止溝と、該掛止溝に掛止すると共に吊下軸の上下端部に設ける掛止片と、を備えた掛止め方式のもの、などの構造とするのが好ましい。
また挟持部材として、吊下軸へ挟持するための弾性を有する挟持本体と、該挟持本体の端部を開くためのツマミ部と、を備えたものとしても良い。コの字状の軸を用いる時には、挟持部材として、吊下軸に挿入して配置する一対の挿入部と、該挿入部に先端を固着した略三角形状の板バネと、その板バネを開いて挿入部の間隔を広げるための操作ツマミと、を備えたものとしても良い。
尚、第2実施形態以降の説明にあたって、第1実施形態と同じ構成には、第1実施形態と同一の符号を付し、それらの説明を省略または簡略化する。
本発明の第1実施形態を図1、図2に基づいて説明する。
1は先端が折畳み可能に取付けられた一対のツルであり、該ツル1の後端部には耳当部11が形成されている。
又、レンズA,Bが傾斜するようにレンズ保持枠6を、図8に示すように折曲(傾斜)させたものとしても良い。この時のツル1と後述するブリッジ7の最大高低差を、レンズAの中心とレンズBの中心との間隔相当の距離にすると良く、吊下軸3を連結杆2に設ける際、レンズ保持枠6の上部の傾斜に合せて平行移動するように傾斜を付けたものとしても良いが、直角に設けたものとしても良い。尚、図中の一点鎖線は目の高さを示す。
又、レンズAとしてサングラスを使用し、レンズBとして凸レンズを使用する際、特に運転席のカーナビやオーディオ機器等を操作した後、直ぐにサングラスに変えて見れば、前方がボケたり或いは距離感に異常を感じることが防止可能となると共に眩しさに対応できるものとなる。更に、レンズAとしてウェアラブル端末グラスを使用し、レンズBとして凸レンズを使用すると、眼鏡としてレンズBを使用しながら、一々眼鏡を外さなくてもウェアラブル端末が使用できるものとなるのである。
このように、本発明品を用いれば、眼鏡を掛け変えなくても簡単に2種類のレンズA,Bがそれぞれ単独状態で使用できるものとなるのである。
本発明の第2実施形態を図10、図11に基づいて説明する。
吊下軸3Eは連結杆2よりも若干前方へ突出させ(図11、図14Aから図14C参照)、四角柱などの多角柱に形成している。また前記吊下軸3Eの下端には鍔状の落下防止部34が一体に成形されている。尚、支持棒42の上端部は吊下軸3Eに固着せず、連結杆2に固着させたものとしても良い。
又、レンズA,Bが傾斜するようにレンズ保持枠6を図示しないが、前後方向へ折曲(傾斜)させたものとしても良い。
尚、前記レンズ保持枠6に上下に異種類のレンズA,Bを分けずに、1つのレンズだけを保持させ、それを交換するものとしても良い。例えば、凸レンズを使用したもの、サングラスを使用したもの、などを複数個用意し、用途によって、それらを交換させるようにしたものとしても良い。
本発明の第3実施形態を図15に基づいて説明する。
ツル1は、段差部12を備えている。段差部12は、蝶番8よりも連結杆2側に設けられ、蝶番8側から連結杆2側をみたときに下向きの段差を構成する。段差部12の先端には、連結杆2の折曲部21が接続されている。
振れ防止部61は、連結杆2の折曲部21に着脱可能に係止される係止部611を備えている。係止部611は、ゴム等の弾性部材で構成され、側面に軸方向のスリット612が形成された円筒状に形成されている。
例えば、挟持本体91を吊下軸3Hから外し、レンズ保持枠6を上下に反転させた後、再び吊下軸3Hへ挟持本体91を挟持させることで、レンズA、Bのどちらに対しても、その中心を目の高さに合致させることができる。
また、挟持部材9を上下移動させることで、レンズ保持枠6が上下移動するため、この場合でも、レンズA、Bのどちらに対しても、その中心を目の高さに合致させることができる。
