The inner surface contact portion 3 is made up of a front contact portion 3b and a rear contact portion 3c through a viewing window 3a, and the outer surface contact portion 4 faces the viewing window 3a of the inner surface contact portion 3. . Note that the viewing window 3a may not be provided.

A plurality of longitudinal ribs 6 are formed on the front contact portion 3b and the rear contact portion 3c of the inner surface contact portion 3, and the longitudinal ribs 6 contact the inner surface Ti of the temple T. A plurality of longitudinal ribs 7 are formed in contact with the outer surface To of the T. The longitudinal rib 6 protrudes toward the outer surface contact portion 4 from the center line SL of the insertion hole 5 of the mounting body 1, and the longitudinal rib 7 protrudes from the center line SL of the insertion hole 5 of the mounting body 1 toward the inner surface contact portion 3. It sticks out to the side. Although these vertically long ribs 6 and 7 have a substantially triangular horizontal cross-sectional shape in the illustrated example, they may have a rectangular shape, a circular arc shape, or the like.

An insertion groove 8 for the temple T is formed in each of the plurality of longitudinal ribs 6 formed on the front contact part 3b and the rear contact part 3c of the inner surface contact part 3. In the illustration, these insertion grooves 8 are formed at the center of each of the longitudinal ribs 6, but they may be formed at positions slightly shifted vertically from the center. Furthermore, although the insertion groove 8 is shown as having a triangular shape, it may be square or arcuate.

A plurality of longitudinal ribs 7 formed on the outer surface contact portion 4 are provided with grooves 9 at a plurality of locations to divide each of the longitudinal ribs 7. In the illustration, these grooves 9 are formed at two places on each longitudinal rib 7 in order to divide each of the longitudinal ribs 7 into three, but the grooves 9 are not limited to dividing into three. It may be divided, or it may be divided into more than three parts. Furthermore, although the cut groove 9 is shown as having a triangular shape, it can also be made into a square shape, a circular arc shape, or the like.

The locking part 2 includes an insertion part 2a of the side part of the shield S provided at the rear end of the outer surface contact part 4, and an insertion part 2a of the side part of the shield S provided at the front end of the outer surface contact part 4. A protrusion 2b that fits into a stopper hole Sa provided near the side of the holder. Although the insertion portion 2a is formed as a gap between the outer surface contact portion 4 and the bent piece 10 protruding from the outer surface contact portion 4, the insertion portion 2a is not limited to being formed in this way. The fitting protrusion 2b has a substantially conical shape to facilitate fitting into the stopper hole Sa of the shield S, but is not limited to such a shape.

The shield S covers the front, upper and lower sides, and both sides of the lenses L of the glasses G, and has an approximately inverted V-shaped cutout on the lower side to prevent the user's nose from touching the lens L when wearing the glasses. A portion Sb may be provided, or a notch Sc into which the insertion portion 2a of the locking portion 2 enters may be provided at the side portion, and the stop hole Sa may be provided near the side portion. In the illustrated embodiment, the shield S covers the upper part of the user's face, but it may cover the entire face of the user.

Furthermore, the shield S is made of a bendable and elastic transparent synthetic resin sheet made of polycarbonate, polyethylene terephthalate, polyester, polyamide, polypropylene, etc., and is treated with anti-fog, anti-reflection, and scratch-resistant treatments. It can be made into a sheet or an anti-glare sheet such as a smoke-colored sheet or a polarizing sheet.

The glasses G have a shape in which the frame F is fitted around the entire periphery of the lens L, but it may also be fitted in a shape from the top edge of the lens L to both side edges, or a shape in which the frame F is fitted only to the top edge of the lens L, or a lens The shape of the glasses G is not limited, such as fixing the temple T directly to the L with a screw. The frame F is preferably made of a metal material such as titanium alloy or stainless steel, or synthetic resin, and a nose pad P is attached to the frame F. Although the lens L is a two-lens lens, it may be a single lens. Alternatively, it may be possible to have only the frame F and no lens L. In addition, when the lens L is a single lens, the nose pad P may be attached to this lens L.

The nose pad P is made of a soft elastic material such as elastomer or elastic rubber, or the same material as the frame F, and has a substantially inverted V shape, and when the entire periphery of the lens L is fitted into the frame F, It is attached to a substantially inverted V-shaped cut portion formed at the center of the lower side of the frame F. Further, when the lens L is a single lens, it may be attached to a substantially inverted V-shaped cut portion formed at the center of the lower side of the lens L.

The temple T is an elongated plate-like member or rod-like member, and is made of a metal material such as titanium alloy or stainless steel, like the frame F. It is preferably made of synthetic resin or the like, and is designed to elastically support the wearer's region from the side of the head to the back of the head. Moreover, although the crane T is made foldable via a hinge between it and the frame F, it may not be able to be folded together with the frame F.

Attaching a shield to eyeglasses using the eyeglass shield attachment of the present invention configured as described above is carried out as follows.

First, when the attachment body 1 is pinched and pressed by placing one's fingers on the top and bottom of the attachment body 1, the insertion hole 5 between the inner surface contact portion 3 and the outer surface contact portion 4 is expanded as shown in FIG. . In this case, since the plurality of longitudinal ribs 7 of the outer surface contact portion 4 are formed with a plurality of cut grooves 9 that divide each of them, when the mounting body 1 is pinched and pressed, these cut grooves 9 are narrowed. The outer surface contact portion 4 is easily curved along these cut grooves 9, and the insertion hole 5 is easily expanded.

Next, with the insertion hole 5 of the mounting body 1 widened, insert it into the temple T of the glasses G from the rear end, and when you stop pressing the mounting body 1 after inserting it, the insertion hole 5 returns to its original state. , the inner surface contact portion 3 of the mounting body 1 contacts the inner surface Ti of the temple T, and the outer surface contact portion 4 of the mounting body 1 contacts the outer surface To of the temple T. Then, in this state, the mounting body 1 is slid with fingers toward the front end of the temple T. In this case, since the front contact part 3b and the rear contact part 3c of the inner surface contact part 3 are visible from the outside of the temple T, it becomes easy to slide the inner surface Ti of the temple T onto the inner surface contact part 3. In addition, when the temple T is a thin rod-shaped member, if the temple T is inserted into the insertion groove 8 of the inner surface contact portion 3 and then slid with a finger toward the front end of the temple T, it will not move vertically. You can slide it smoothly without any trouble.

Then, by stopping the mounting body 1 at an appropriate position on the front end of the temple T of the glasses G, the glasses can be provided with the shield mounting tool of the present invention.

Therefore, both ends of the shield S are bent inward as shown in FIG. 9, and one side (the notch Sc) is inserted into the insertion part 2a of the locking part 2 of the mounting body 1. At the same time, the fitting protrusion 2b of the locking part 2 of the mounting body 1 is fitted into the locking hole Sa near one side, and the other side (the notch Sc) is fitted into the locking hole Sa of the mounting body 1. If the insertion part 2a of the attachment part 2 is inserted into the insertion part 2a, and the fitting protrusion 2b of the locking part 2 of the mounting body 1 is fitted into the stopper hole Sa near the other side of the insertion part 2a, as shown in FIG. The shield S can be attached to the attachment body 1 which is stopped at an appropriate position on the front end of the crane T of G. It is also possible to attach a plurality of shields S to the attachment body 1 by repeating the same operation after attaching the shield S. In this way, if the shield S becomes dirty due to adhesion of droplets, etc., the dirty outermost shield S can be removed without removing the attachment body 1 from the glasses G or removing the glasses G from the face. This makes it convenient, as well as excellent in terms of safety and hygiene.

By wearing the glasses G to which the shield S is attached in this manner, the shield S can cover the user's face. In this case, as described above, the shield S has both sides (notches Sc) inserted into the insertion part 2a of the locking part 2 of the mounting body 1, and the shield S is inserted into the stopper hole Sa near both sides. Since the fitting protrusion 2b of the locking portion 2 of the mounting body 1 is fitted, the mounting body 1 can be stably and reliably attached to the mounting body 1. Furthermore, in the mounting body 1, the longitudinal ribs 6 of the front contact part 3b and the rear contact part 3c of the inner surface contact part 3 and the longitudinal ribs 7 of the outer surface contact part 4 are arranged on the inner surface Ti and the outer surface of the temple T of the glasses G, respectively. Contact To. In this case, if the temple T is a plate-like member, its plate-like surface is pressed by the vertically long ribs 6 and 7, so that it can be reliably attached to the temple T in a stable state. In addition, if the said vine T is a plate-shaped member, even if it bends or bends to some extent, it will be reliably attached to this vine T in a stable state. Furthermore, even if the temple T is a thin rod-like member, if the temple T is inserted into the insertion groove 8 of the inner surface contact portion 3, it can be stably attached to the mounting body 1 without wobbling. You can keep it.

In addition, when the user's face is covered with the shield S, if the position of the shield S is too close to the user's face and the tip of the nose gets stuck in the shield S, the mounting body 1 should be attached to the temple T of the glasses G. When pushed further toward the front end with a finger, the attachment body 1 slides forward, so that the shield S is also pushed forward, and the shield S no longer gets stuck on the tip of the user's nose. In addition, when the position of the shield S is too far from the user's face and there is too much gap between the user's face and the shield S, the mounting body 1 can be moved toward the rear end of the temple T of the glasses G with a finger. When pushed back, the attachment body 1 slides backward, so that the shield S is also pushed back, making it possible to create an appropriate gap between the shield S and the user's face.

Therefore, as mentioned above, with the eyeglass shield attachment of the present invention, the shield S can be easily attached to the face and can be attached stably.

Furthermore, the eyeglass shield attachment of the present invention allows the attachment position of the shield S on the face to be adjusted to an appropriate position depending on the user.
