DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for molding a spectacle frame using a hard synthetic resin as a material, in which fixed upper and lower end portions of left and right lens frames into which lenses are fitted are fixed. After the connecting bridge is integrally swelled and formed at intervals, a buffer made of a soft synthetic resin is press-fitted and welded so as to surround the connecting bridge and conform to the shape of the face, and the wind passing through the outer surface of the sunglasses Is not caught in the inner surface of the sunglasses by the buffer that swells up and down inside the spectacle frame, effectively protecting the wind without directly hitting the eyes, and preventing dust floating in the air from entering the eyes The present invention relates to a method for integrally manufacturing sunglasses with a cushion to protect the sunglasses.

2. Description of the Related Art In recent years, various types of sunglasses having many fashion elements have been marketed, and the main purpose of wearing the sunglasses is to protect eyes from ultraviolet rays caused by direct sunlight in summer. Although it was used, it was used all year round, ignoring the original meaning of use due to the sense of fashion, and it has been moving or active at a considerable speed outdoors in skiing, cycling, motorcycles, etc. Goggles or goggles are used to prevent direct exposure of the eyeballs to the wind and to protect dust that floats in the air from entering the eyes, especially in indoors including factories that generate dust, such as dynamic outdoor sports. They are wearing sunglasses.

[0003] In fashionable sunglasses, a windproof effect can be obtained in a sense. On the other hand, in view of the dustproof effect, air containing dust enters from the gap between the periphery of the spectacle frame and the face. Often, there is a concern that dust floating in the air may get into the eyes.In order to prevent this, in order to eliminate the gap between the surroundings of the spectacle frame and the face, place the synthetic leather hood on the spectacle frame. It is connected to the rim and the eyeglass vines on both sides to prevent this, or similarly, a dustproof hood made of hard synthetic resin is adhered to the upper edge and the both sides of the eyeglass frame via an adhesive to prevent dust. Is trying to get.

However, in this case, in the former dust hood made of synthetic leather, since soft synthetic leather is attached to the upper edge of the spectacle frame and the vines on both side edges thereof by attaching studs, the spectacle and the face are not connected to each other. Since the gap cannot be covered properly, air containing dust is often apt to flow in. In addition, sometimes the hood is so flexible that it obstructs the field of view. When it is bonded, it takes a considerable amount of time to beautifully bond them, and furthermore, there is a fear that the solvent of the adhesive discolors not only the eyeglass frame but also the synthetic resin lens. At the same time, peeling is likely to occur due to long-term use, and furthermore, when colliding with others during exercise, etc., the periphery of the hard synthetic resin dustproof hood directly collides around the eye socket around the eyes. Those having a possibility that allowed to damage the peel.

In goggles which are effective for wind and dust protection, a spectacle frame and a hood surrounding the eyeglass frame are integrally formed large and firmly, and a peripheral portion on the face is a thick sponge-like buffer. Is attached to protect the eyes, so from the viewpoint of windproof and dustproof, it sufficiently fulfills its function, but the goggles themselves are too large and move,
Due to the inconvenience of storage, it is currently avoided that only specific skiers use it in other off-season or in workplaces where wind and dust protection are effective.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a spectacle frame made of a hard synthetic resin is provided with a buffer made of a soft synthetic resin that eliminates a gap between the face and the inner upper end and the inner lower end of the lens frame. Pressing and welding along the shape of the face so that the eyes are not directly exposed to the wind and floating dust does not enter the eyes.Furthermore, even if the spectacle user collides with others, the soft synthetic resin buffer An object of the present invention is to provide an integrated manufacturing method of sunglasses that can function as original protective glasses without damaging the periphery of the orbit.

[0007]

According to the present invention, there is provided a lens for fitting left and right lenses when molding a spectacle frame made of a hard synthetic resin in order to combine different materials. After forming a narrow connecting bridge integrally with the inner upper end of the frame and at a fixed interval from the inner lower end of each lens frame by a plurality of connecting bodies, the connecting bridge is formed. A buffer body surrounding and conforming to the shape of the face is press-fitted and welded with a different soft synthetic resin to form an integrated sunglass with a different material, thereby achieving the object.

[0008]

According to the present invention, when combining different materials having different properties, no solvent such as an adhesive is used at all. The spectacle frame is molded from a hard synthetic resin with low specific gravity, excellent impact resistance, weather resistance and chemical resistance, and good deformability so that the solvent does not diverge and the buffer is not peeled off by the soft synthetic resin. First, as a first step, a narrow connecting bridge is integrally formed by a large number of connecting bodies at a fixed interval between the inner upper end and the lower end of the lens frame in which the lens is fitted, and the lens frame is formed. After molding, as a second step, surrounding the connecting bridge of the lens frame, and having excellent elasticity over the lens groove for fitting the lens, a cushion of soft synthetic resin having excellent heat resistance and weather resistance is applied to the face. Press-fit welding along the shape In each of these steps, the cushioning body efficiently covers the gap between the spectacle frame and the face to prevent the ingress of floating dust, since these steps are formed by molding means using a mold or the like. At the same time, the spectacle frame and the buffer are press-fitted so as to surround the connecting bridge integrally bulging on the inner surface of the lens frame as described above. Since there is no fear of damaging the face with a soft synthetic resin buffer, the sunglasses can be used with an extremely fashionable feeling, unlike conventional sunglasses.
