A recess 24 is formed in front of the support shaft 23 and parallel to the axis B of the support shaft 23 on both side surfaces.

Continuing from the slider portion 22, a stem portion 25 constructed so that the slider portion 22 can be moved back and forth by a predetermined distance L and swung by a predetermined front inclination angle θ within a front end portion 26 thereof. It is connected. Front and upper and lower end surfaces of the front end portion 26 are opened so that the slider portion 22 can be moved in and out and swung, and both end portions of the support shaft 22 penetrate through both side surfaces to slide the predetermined distance L. A guided stem slot 27 is transparently provided.

A pair of click projections corresponding to the pair of recesses 24 are formed on both inner side surfaces of the front end portion 26 near the front end surface.
28 are projected. Since there is no opening like the stem slot 27 in the inner part of the front end 26, and the cross section is surrounded by a hollow shape, the slider part 22 is allowed to slide only and cannot swivel. Has been The pull-out distance at which the slider 22 can be swung is about 1/2 of the total distance L, but the pull-out distance is not limited to this.

Further, the stem portion 25 is provided with an ear pad portion 29 at the rear thereof, and the ear pad portion 29 has an elastic lower ear so that the slot 30 is provided correspondingly to a portion contacting the ear. The pad portion 29a is formed. The lower ear pad 29a
In order to soften the contact with the ears, it is preferable to use rubber or a plastic material, but the upper ear pad portion 29b that does not directly contact the ears is not limited to the plastic material and may be a metal material.

The glasses 20 of the present invention configured as above
When observing a relatively distant place through the spectacle lenses 11 and 12 in a normal state, is used in a frame state in which it is fixed at a fixed point similar to the conventional spectacles 10, but when desk work, the slide part 22 is moved forward. A predetermined distance L is pulled out, the front inclination angle θ is further inclined to a predetermined front inclination angle θ, and the front inclination angle θ is fixed by the click means composed of the click protrusion 28 and the concave portion 24.

The front inclination angle θ is usually set within the range of 40 ° to 50 °, but is not necessarily limited to this angle. Compared to the fixed type like the conventional glasses 10, when looking at a close drawing through the glasses lenses 11 and 12 which are tilted forward like this, compared to the fixed type like the conventional glasses 10, in a comfortable posture, only the line of sight S is tilted forward. By adjusting to θ, desk work can be performed. Further, when it is necessary to look at a distant place, if only the line of sight S is returned to be substantially horizontal, there is no frame that blocks the line of sight S at the upper edge peripheral portions 11a, 12a of the spectacle lenses 11, 12, so that it is easy. It will be possible to observe a long distance.

Further, in the earpiece 29, at least the lower earpiece 29a which comes into direct contact with the ear is formed relatively thin, so that the flexibility is increased and the eyeglasses 20 are easily deformed. Even if the user pulls out forward and tilts forward while wearing the earphones on the ears, the contact with the ears is softened and the fit is enhanced.

Even if the sliding of the slide portion 22 by the predetermined distance L is eliminated and only the turning motion of the predetermined front inclination angle θ is possible, the switching between the perspective and the perspective is possible. .
