Abstract

PURPOSE:To suppress the generation of a trouble and to handle easily the titled lens frame by sliding a lens frame vertically without fixing the lens frame to sidepieces and automatically providing the lens frame with a proper inclined angle. CONSTITUTION:The lens frame 1 is fixed to the sidepieces 2. A magnet 9 is arranged on the lower part of an inclined-V shape-like body 5 or the lower part of the inside of an engaging groove 7 and one end or the whole of a cylindrical supporting body 6 or a tongue-like supporting body 8 of the other sidepiece is formed by a magnet. When the lens frame 1 is pushed up without removing the glasses from the face, the lens frame 1 can be smoothly moved because there exists play in the connection between the lens frame 1 and the sidepieces 2. Since the whole lenses 1 are moved in the glass frame without the movement of fine parts such as the movement of a noise piece or the sidepieces, the generation of troubles is suppressed and the handling can be made easy.

にした眼鏡枠に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bifocal eyeglass frame having a continuous focus lens, and in particular, the lens frame (1) is slid up and down to adjust the lens portion according to the distance of the object to be viewed. The present invention relates to a spectacle frame which is easy to use and which allows bifocal glasses to be used without inconvenience by setting the lens frame (1) at an appropriate inclination angle with respect to the eyes.

にくいという不便さを免れなかった。Generally, with progressive multifocal lenses, the upper part of the lens is for distance vision, and the lower part is for near vision, but because the lens is fixed, the relationship between the lens and the line of sight means that while distance vision is easy to see, near vision is difficult to see. I couldn't escape the inconvenience.

た時に眼鏡の重みが鼻当てに集中してかかるため、鼻梁
を圧迫し装着感が不快である、等の欠点があった。Conventionally, in order to improve this problem, some attempts have been made to adjust the glasses frame by moving the nose pad and bending the temples. However, this type of eyeglass frame is not only expensive to manufacture due to its delicate structure, but also prone to failure; ■ requires some experience and is cumbersome to operate; and the θ lens has several ranges of movement. However, when the O-lens is moved upward, the weight of the glasses is concentrated on the nose pad, which presses the bridge of the nose and makes it uncomfortable to wear.

本発明はこれ等の欠点を解消し、簡単か？気持よく使用
できる眼鏡枠を提供するものである。Does the present invention solve these drawbacks and is it simple? To provide an eyeglass frame that can be comfortably used.

本発明の構造は、眼鏡枠を大きく二つの部分に分け、一
つはレンズ枠（１）の部分と、もう一つは左右のつる（
２）をブリッジ（３）にて連結した部分でありそのブリ
ッジ（３）からクリングス（４）を出している。The structure of the present invention is to divide the eyeglass frame into two parts, one being the lens frame (1) and the other being the left and right temples (
2) are connected by a bridge (3), and the clings (4) come out from the bridge (3).

6). Alternatively, fitting grooves (7) are provided at both ends of the lens frame (1), into which the tongue-shaped support (8) protruding from the end of the temple (2) is fitted.

又は磁石が吸着して落下せず、眼に最適の位置を保つこ
とができる。Since the present invention has the above-mentioned configuration, when viewing objects for near purposes, that is, using the lower part of the lens, the lens frame (
1) Push up. Since there is play in the connection between the lens frame (1) and the temple (2), lens # (1) can move smoothly. The pushed-up lens frame is moved by the magnet (
9) and the iron pieces or magnets of the cylindrical support (6) or the tongue-shaped support (8) are attracted and do not fall, and the optimal position for the eye can be maintained.

着力はほどほどであって、押し下げることによりレンズ
粁（（１）は落下して、遠用に適した位置となる。For distance viewing, that is, when viewing through the upper part of the lens, push up the lens frame (1) while wearing the glasses. The attraction force of the magnet (9) is moderate, and by pushing down, the lens cap ((1)) falls to a position suitable for distance use.

なおレンズの下部を使用する時は、手近下方の物を視る

枠（１）が前に１００位倒れ、自動的に最適の傾斜が得
られ−るようになっている。When using the lower part of the lens, it is necessary to bring the lower part of the lens closer to the eye in order to see things near and below, so the lens is tilted 10' closer to the vertical than for distance vision, which improves the visibility. must pass through the optical center of the lens correctly. Therefore, in the present invention, the 7-shaped body (5
) or at the bottom of the insertion groove (7), the lens frame (1) will tilt forward by 106 degrees as the lens frame (1) is pushed up, automatically achieving the optimal inclination. It is becoming more and more popular.

ある。As explained above, the spectacle frame for progressive multifocal lenses of the present invention has a structure in which the entire lens frame (1) is moved, and minute parts such as those used to operate the nose pads are not moved. It has the following advantages: it is less likely to occur, it is easy to operate, it has a wide range of vertical movement, and there is no discomfort when wearing it.
