[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in sunglasses, and more particularly to an improvement in goggle type sunglasses in which light is prevented from entering between the sunglasses and the forehead.

[0002]

2. Description of the Related Art Sunglasses are practical products for preventing glare in dazzling outdoors. The prevention of glare is achieved by a dark-colored lens with low translucency, and the use of a lens with low translucency reduces the light transmitted through the lens, so that a high anti-glare effect can be expected. However, in sunglasses that reduce the amount of transmitted light, if strong light enters the back of the sunglasses from the gap between the sunglasses and the face, the light inserted from the gap directly enters the eyes or is reflected by the lens and enters the eyes. There was a phenomenon in which the view behind the weakened lens became difficult to see. It is a contradiction that the higher the sun's intensity, the higher the need for glare prevention, but the higher the sun's intensity, the stronger the light entering the backside of the sunglasses, and the more the sunglasses with a strong antiglare effect cannot be used.

[0003] For this reason, sunglasses have been sold which take the periphery of the sunglasses backwards in a cylindrical shape and attempt to close the gap with the face like underwater glasses. But,
Since the cylinder brought out behind such sunglasses was often made of a hard resin, the cylinder could not respond to individual differences in the shape of the face, leaving a gap between the face and the sunglasses, The light entering the back could not be completely shut out.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is a technical object of the present invention to prevent light from entering the back of the sunglasses beyond the individual difference in the shape of the face.

[0005]

The means employed in the present invention for solving the above problems will be described below. The sunshade base is brought out to the upper rear of the front supporting the lens in front of the eyes, and a predetermined flexibility is provided. The fitting bar provided is connected to the sunshade base only at both ends while overlapping the sunshade base, so that the fit bar is flexed so that the center of the bar can move forward and backward with respect to the base. is there.

In the present invention, light is blocked by the sunshade base and the fit bar. The bar moves forward and backward while the sunshade base and the fit bar overlap, thereby making it possible to cope with a change in the shape of the face. That is, the retractable fit bar closes the gap between the face and the sunshade base. In normal use, light entering the back of the sunglasses shines from above, so it is sufficient that the sunshade base and the fit bar extend at least to the rear of the upper part of the sunglasses.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.

A front 1 is obtained by molding a nylon resin. This front 1 has a rim 11
The monocular lens 3 whose central portion in the lateral direction is confined can be fitted to the rim 11. The rear part of the rim 11 is extended in a predetermined shape, and two holes are provided on both sides of the rear part of the rim 11 in the up and down direction of the extending part to form the temples 13 and 13.
・ Because 4 can be pivoted, a bridge 14 is provided at the lower rear of the rim 11 so that it sits on the nose when wearing sunglasses.
Is arranged. Further, a sunshade base 12 having a curved shape with a central portion advanced in a planar shape is extended from a rear upper portion of the rim 11 so as to follow the face to some extent. These sunshade bases 12, 13 and 13, and bridge 14 are formed so as to be smoothly continuous (see FIG. 1).

The fit bar 2 is connected to a sunshade base 12 located at the upper rear part of the rim 11 of the front 1. The fitting bar 2 is a resin bar having a U-shaped cross section, and is curved in accordance with the curve of the sunshade base 12. Both ends of the bar are sunshade with the sunshade base 12 being sandwiched inside the U-shape. Connected to base 12. Further, a convex portion 21 is provided inside the U-shape in the center of the fit bar 2, and concave portions 15, 15... Are arranged in front and rear at corresponding portions of the sunshade base 12.
Are fitted in any one of the recesses 15, 15,..., So that the center portion of the fit bar 2 is fixed. And
When this fitting is changed, the position of the center portion of the fit bar 2 changes back and forth, the bending state of the fit bar 2 changes, and the distance of the center portion of the fit bar 2 from the rim 11 changes. As a result, the light blocking member taken out behind the upper part of the rim of the sunglasses can correspond to various face shapes (see FIGS. 2 to 4). In order to effectively block light, the material of the sunshade base and the fit bar should be opaque, and there should be no gap between the two even if the fit bar moves back and forth. For this reason, they should be arranged in an overlapping manner. In this embodiment, the overlapping is realized by sandwiching the sunshade base between the U-shaped fit bars. Also, in order to bend the U-shaped fitting bar straight, a material that is not so hard should be used for the fitting bar. Keep this in mind as the force fixing the part is weakened. Furthermore, since the sunshade base needs to have a predetermined curvature in a planar shape and also to be curved in a frontal shape in conformity with the shape of the upper edge of the rim, the curve of the fit bar is set accordingly.

[0010] The movement of the fit bar exerts an adjustment function when the forehead and the sunglasses are too far apart, or when the forehead and the sunglasses do not match.

[0011]

[Effects of the Invention] As described above, according to the present invention, the adoption of the retractable fit bar enables adjustment of the light shielding member according to the wearer's face, thereby preventing light from entering the back of the sunglasses. Can be prevented. For this reason, sunglasses having both a glare prevention effect and forward visibility can be realized, and have high practical value.
