Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an eyeglass frame, and more specifically, to an eyeglass frame that can be suitably used for bifocal eyeglasses.

[Problems to be solved by the prior art and the invention] Bifocals are so-called bifocals in which, for example, the upper half of the lens can be used as a myopic lens part and the lower half can be used as a presbyopia lens part in a spectacle frame. The lens is attached.

Usually, when using these bifocals, both the perspective and the perspective can be clearly seen by simply directing the line of sight to the focal points of the perspective without moving the head.

However, there is a limit to changing the line of sight depending on the position of the object to be seen. For example, if you look at the lens part for presbyopia in the lower half while looking down on your face and then try to look at a distance in front of you, you must change the angle of inclination of your face in order to drastically change the viewing angle. There was an inconvenience that it would not happen.

Therefore, as shown in FIG. 5, in order to eliminate the inconvenience,
A step 13 is formed in the middle of both legs supporting the nose pad 2.
There is proposed a spectacle frame which is provided with a substantially U-shaped nose pad support member 11 having a guide and a guide 12 for guiding the nose pad support member 11 on the lens frame 3.

Bifocals using the spectacle frame, when using the desired focus of the bifocal lens, slide the nose pad support member 11 up and down through the guide 12, and at the step 13, raise the glasses up. It was proposed to suppress the movement of the line of sight as much as possible by fixing it in the position or the lower position.

However, the glasses that enable the vertical movement are
Since the vertical movement is a slide type, the glasses are removed to perform the vertical movement, and the nose pad support member 11 is slid through the guide 12 to change the lens to a desired position. However, it has the trouble of wearing the glasses again, and the nose pad support member 11 and the guide 12 are worn by repeated use, and as a result, the plating of the nose pad support member 11 and the guide 12 is peeled off. There is an inconvenience that the eyeglasses cannot be rusted or that the step 13 disappears and the glasses cannot be fixed at a desired position.

Further, the slide type spectacle frame has a disadvantage that the spectacle frame is relatively heavy because the accessory members such as the nose pad support member 11 and the guide 12 are specially provided.

This invention was made in consideration of the above circumstances.

An object of the present invention is to provide a spectacle frame in which a desired focusing lens can be used semi-automatically without undue movement of the line of sight and without removing the spectacles and which has a long service life. .
