(イ) 考案の分野
この考案は、例えば遠視の人が視力を矯正する
ために用いるような眼鏡に関する。[Detailed description of the invention] (a) Field of the invention This invention relates to glasses used, for example, by people with farsightedness to correct their visual acuity.
(ロ) 考案の背景
従来、上述例の眼鏡としては例えば、左右のレ
ンズの下部を老眼用の凸レンズに形成した眼鏡が
ある。(B) Background of the Invention Conventionally, as the above-mentioned glasses, for example, there are glasses in which the lower portions of the left and right lenses are formed into convex lenses for presbyopia.
しかし、眼鏡を着用する使用者の左右の瞳孔間
距離には個人差があるが、上述の眼鏡はレンズを
保持するフレームに、凸レンズが固定されている
関係上、この凸レンズの向きを可変することは困
難であり、この結果、使用者の左右の瞳孔間距離
に対応した凸レンズの光軸調整ができない問題点
があつた。 However, there are individual differences in the distance between the left and right pupils of a user who wears glasses, but since the above-mentioned glasses have a convex lens fixed to the frame that holds the lens, it is not possible to change the direction of this convex lens. As a result, there was a problem in that the optical axis of the convex lens could not be adjusted in accordance with the distance between the left and right pupils of the user.
この問題点について具体例をあげて更に説明す
ると、例えば瞳孔間距離の標準の人に合わせて凸
レンズの向きを設定すると、瞳孔間距離が標準よ

孔に至る入射光線が凸レンズに入射する角度は直
角よりも狭い鋭角となり、文字等の目視対象が左
右方向に変形したり、ぼやけたり或は歪んだ状態
となる問題点を有していた。 To further explain this problem by giving a specific example, for example, if the direction of a convex lens is set to match a person with a standard pupillary distance, a person with a wider than standard pupillary distance will be able to see objects at close range through the convex lens. When viewing, the angle at which the incident light ray from the visual object to the pupil of the above-mentioned person enters the convex lens is an acute angle narrower than a right angle, causing the visual object such as letters to be deformed in the horizontal direction, blurred, or distorted. It had the following problems.
(ハ) 考案の目的
この考案は、使用者の左右の瞳孔間距離に対応
して光軸調整を行なうことができる眼鏡の提供を
目的とする。(c) Purpose of the invention The purpose of this invention is to provide eyeglasses that can adjust the optical axis according to the distance between the left and right pupils of the user.
(ニ) 考案の要約
この考案は、左右のレンズ下部に形成した各凸
レンズの一側をレンズフレームに枢着する枢着手
段と、この枢着手段を回動中心として左右の各凸

た眼鏡であることを特徴とする。(d) Summary of the invention This invention consists of a pivoting means for pivotally attaching one side of each convex lens formed at the lower part of the left and right lenses to a lens frame, and a pivoting means for pivotally attaching one side of each convex lens formed at the bottom of the left and right lenses to the lens frame, and a pivoting means for pivoting the other side of each of the left and right convex lenses around this pivoting means as a rotation center. The eyeglasses are characterized by being equipped with an optical axis adjusting means that rotates and fixes.
(ホ) 考案の効果
この考案によれば、凸レンズの一側を上述の枢
着手段で枢着すると共に、凸レンズの他側を光軸
調整手段により回動固定自在に構成しているの
で、上述の枢着手段を回動中心として凸レンズの
向きを可変することができる。(e) Effects of the invention According to this invention, one side of the convex lens is pivotally connected by the above-mentioned pivoting means, and the other side of the convex lens is configured to be rotatable and fixed by the optical axis adjusting means. The direction of the convex lens can be changed using the pivot means as the center of rotation.
この結果、使用者の左右の瞳孔間距離に対応し

いる。 That is, the above-mentioned optical axis adjusting means 13
1 Concave groove 1 formed in the hook 12 facing the lower surface
4, a spring 15 and a ball 16 disposed in the concave groove 14, and a plurality of, for example, two, ball engaging grooves 17 and 18 formed on the lower surface of the above-mentioned protrusion 11. 16 is selectively engaged and held in a plurality of ball engagement grooves 17 and 18, so that the outer side of the convex lens 3 is fixedly rotated about the aforementioned pivot threaded rod 10 as a rotation center.
なお、上述の各レンズ２，３としてはガラスや
透明合成樹脂を、また上述のフレーム４〜９とし
ては合成樹脂、べつこう、金属等を用いる。 The lenses 2 and 3 described above are made of glass or transparent synthetic resin, and the frames 4 to 9 are made of synthetic resin, plastic, metal, or the like.
図示実施例は上記の如く構成するものとして、
以下作用を説明する。 The illustrated embodiment is configured as described above.
The action will be explained below.
いま前述のボール１６が第５図に示す如く一方

想線で示す位置に配設される。 Therefore, when the lower lens frame 9 is rotated about the aforementioned pivot threaded rod 10 in the direction of the arrow in FIG. After sinking into the concave groove 14 against the force of 15, the force of the spring 15 causes the ball to protrude again at the opposing position of the other ball engaging groove 18 and engage the ball engaging groove 18, so that the left and right convex lenses 3, 3 is disposed at the position shown by the imaginary line in FIG.
このように凸レンズ３，３の内側を枢支ネジ棒
１０で枢着すると共に、凸レンズ３，３の外側を
光軸調整手段１３により、回動固定自在に構成し
ているので、上述の枢支ねじ棒１０を回動中心と
して凸レンズ３，３の向きを可変することができ
る。 In this way, the inner sides of the convex lenses 3, 3 are pivotally connected by the pivot threaded rod 10, and the outer sides of the convex lenses 3, 3 are configured to be rotatable and fixed by the optical axis adjustment means 13, so that the above-mentioned pivot support can be achieved. The orientation of the convex lenses 3, 3 can be varied with the threaded rod 10 as the center of rotation.
このため、例えば左右の瞳孔間距離L1が第７
図に示す標準の人の場合には、凸レンズ３，３を
同図の実線位置に設定し、また瞳孔間距離L2が
標準より広い人の場合には、凸レンズ３，３を同
図の仮想線位置に設定することで、使用者の左右
の瞳孔間距離L1，L2に対応した凸レンズ３，３
の光軸調整を行なうことができる効果がある。 For this reason, for example, the distance between the left and right pupils L 1 is the 7th
In the case of the standard person shown in the figure, the convex lenses 3, 3 are set at the solid line position in the figure, and in the case of a person whose interpupillary distance L2 is wider than the standard, the convex lenses 3, 3 are set in the virtual position shown in the figure. The convex lenses 3, 3 corresponding to the user's left and right pupillary distances L 1 and L 2 can be set in the linear position.
This has the effect of making it possible to adjust the optical axis.
この結果、使用者が至近距離の目視対象Ａを見
る場合、目視対象Ａから使用者の瞳孔B1，B2に
至る入射光線C1，C2は、瞳孔間距離L1，L2の大
小にかかわらず、凸レンズ３に対して略直角に入
射するので、文字等の目視対象が左右方向に変形
したり、ぼやけたり或は歪んだ状態となるのを防
止することができる。 As a result, when the user looks at the visual object A at a close distance, the incident light rays C 1 and C 2 from the visual object A to the user's pupils B 1 and B 2 are determined by the size of the interpupillary distance L 1 and L 2 Regardless, since the light enters the convex lens 3 at a substantially right angle, it is possible to prevent objects to be viewed, such as characters, from being deformed in the left-right direction, blurred, or distorted.
以上要するに、この実施例によれば、使用者の
左右の瞳孔間距離に対応した凸レンズ３の光軸調
整を行なうことができる効果がある。 In summary, this embodiment has the advantage that the optical axis of the convex lens 3 can be adjusted in accordance with the distance between the left and right pupils of the user.
