DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to dustproof glasses for protecting eyes from dust, splash, wind pressure, and the like.

[0002]

2. Description of the Related Art Conventionally, this kind of dustproof eyeglasses is often composed of an eyeglass body surrounding the front of an eye and a telescopic band attached to the eyeglass body. When wearing the dustproof glasses, the band is stretched while pressing the glasses body against the face and fitted to the head. Generally, the eyeglass body is a pair of eyeglasses positioned at an interval in front of the eye, left and right side plate portions extending rearward from left and right side edges of the eyeglass portion and abutting on the sides of the eye, and rearward from the upper edge of the eyeglass portion. And a bottom plate portion extending rearward from the lower edge of the eyeglass portion and abutting below the eye, and the like.

However, in the conventional dustproof glasses, the band is stretched while the spectacle body is pressed against the face and fitted to the head, so that there is a problem that the wearing is not easy. Furthermore, dustproof glasses are often worn simultaneously with the head protection helmet.If the dustproof glasses are worn before the helmet, the dustproof glasses may come into contact with the helmet when it is attached or slipped off, or the dustproof glasses may be removed. Since the helmet's ear straps are in the way, you will not be able to remove the dust-proof glasses without removing the helmet. Conversely, when the helmet is worn first, it is troublesome to carry the dust-proof glasses band to the back of the head so that the helmet larger than the head is fumbled.

[0004] When the dust-proof glasses become unnecessary after insertion, it is common to pull the main body of the glasses toward the front of the helmet and shift them so that they are fixed near the front of the helmet by the contraction force of the band. However, the eyeglass body slips toward the top at any time, which is both annoying and dangerous. In order to prevent this displacement, there is also known a method of fixing the band by attaching a pair of left and right dustproof spectacle band fixing brackets to the helmet, but in this case, since the brackets bulge out of the helmet, for example, construction work When passing through a narrow passageway in the middle of the site, there is a danger that the metal fittings may get stuck, and the cost and weight of the metal fittings are added to the helmet.

Further, in the ordinary dustproof glasses, since the left and right side plates of the glasses extend rearward, the ear hooks cannot be folded, and it is not easy to easily store them in pockets or the like.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide dust-proof glasses that can be easily mounted and stored.

[0007]

According to a first aspect of the present invention, there is provided a dustproof spectacles for protecting an eye by being worn on a face, and having flexibility and surrounding the front of the eye.
